Cartridge for testing an in particular biological sample

The present invention relates to a cartridge for analysing and/or testing an in particular biological sample according to the preamble of claim 1 .

Preferably, the present invention deals with analysing and testing a sample, in particular from a human or animal, particularly preferably for analytics and diagnostics, for example with regard to the presence of diseases and/or pathogens and/or for determining blood counts, antibodies, hormones, steroids or the like. Therefore, the present invention is in particular within the field of bioanalytics. A food sample, environmental sample or another sample may optionally also be tested, in particular for environmental analytics or food safety and/or for detecting other substances.

Preferably, at least one analyte (target analyte) of a sample can be determined, identified or detected by means of the cartridge. In particular, the sample can be tested for qualitatively or quantitatively determining at least one analyte, for example in order for it to be possible to detect or identify a disease and/or pathogen. Within the meaning of the present invention, analytes are in particular nucleic-acid sequences, in particular DNA sequences and/or RNA sequences, or proteins, in particular antigens and/or antibodies. In particular, by means of the present invention, nucleic-acid sequences can be determined, identified or detected as analytes of a sample, or proteins can be determined, identified or detected as analytes of the sample. More particularly preferably, the present invention deals with systems, devices and other apparatuses for carrying out a nucleic-acid assay for detecting or identifying a nucleic-acid sequence or a protein assay for detecting or identifying a protein. The present invention deals in particular with what are known as point-of-care systems, i.e. those with the option of carrying out tests on site and/or independently from a central laboratory or the like. Preferably, point-of-care systems can be operated autonomously and/or independently of a mains network for supplying electrical power.

US 5,096,669 discloses a point-of-care system for testing a biological sample, in particular a blood sample. The system comprises a single-use cartridge and an analysis device. The cartridge comprises a receptacle for the sample, it being pos- sible for the receptacle to be closed by a cap once the sample has been received. The cartridge is then inserted into the analysis device in order to carry out the test. The cartridge comprises a microfluidic system and a sensor apparatus comprising electrodes, which apparatus is calibrated by means of a calibration liquid and is then used to test the sample. A waste cavity for receiving liquids is fluidically connected to the sensor apparatus.

Furthermore, WO 2006/125767 A1 discloses a point-of-care system for integrated and automated DNA or protein analysis, comprising a single-use cartridge, an analysis device comprising a control device and comprising means for receiving and processing signals, the control device being designed to fully automatically process and evaluate molecular-diagnostic analyses using the single-use cartridge.

US 201 1/0120580 A1 discloses a device in the form of a flat plate which is em- ployed in the detection and analysis of blood antigens. Channels of the device can be blocked by actuation of a flexible cover plate made of four layers which are shown to have similar thicknesses.

US 2005/0266582 A1 discloses a microfluidic chip for performing assays. The de- vice comprises a valve which can be closed by pressing to the bottom of a channel a gas-permeable membrane and an optional bonding layer covering said channel.

US 2005/0031494 A1 discloses a device for thermal processing of multiple samples at the same time. The device may comprise seal structures for occlusion of con- duits which are formed by an adhesive on one side of the conduit that can be adhered to the opposite site of the conduit, thereby closing the conduit. Subsequent opening of the conduit is not mentioned. These seal structures do not constitute valves, in particular in the sense of the present invention. Valves arranged on or in the cartridge are used to control the flow rate or fluid flow of the sample and/or another fluid in point-of-care systems of this type. These valves may for example be arranged upstream and/or downstream of a measuring or metering cavity, mixing cavity, treatment or reaction cavity and/or sensor apparatus of the cartridge, in particular in order to control and/or influence the reactions and/or measurements as desired.

For example, WO 2010/136298 A1 discloses a method for controlling an instrument comprising an array of valves that each control a fluid flow in an associated flow channel. The valves are each actuated by applying a compressive force, exerted in particular by at least one actuator, a valve being open and it being possible for a fluid to flow in an associated flow channel when no compressive force is applied, and the valve being closed and the fluid flow being stopped in the associated flow channel when compressive force is applied to the valve.

The problem addressed by the present invention is to provide an improved cartridge for testing and/or analysing an in particular biological sample, a compact and/or cost-effective construction or design, reliable, gentle, hygienic and/or simple testing of the sample and/or improved, in particular reliable, simple and/or rapid, control of the fluid flow preferably being made possible, facilitated or supported.

The above problem is solved by a cartridge according to claim 1 . Advantageous developments are the subject of the dependent claims.

The cartridge preferably comprises at least one valve comprising a preferably cylindrical valve seat, the valve seat projecting into a valve chamber of the valve, preferably centrally. Preferably, a wall of the valve that is flexible at least in part can be pressed against the valve seat, in particular in order to close the valve. The preferably centrally arranged valve seat makes it possible to rapidly control the fluid flow through the valve chamber. In particular, the required deflection of the wall is reduced by the valve seat in order to close the valve. In this way, the load on the wall or the material fatigue of the wall is reduced or slowed. One aspect of the present invention is that the cartridge comprises a preferably elastically deformable and/or planar cover or layer, the cover or layer covering and/or reinforcing the valve or the wall of the valve on a side remote from the valve chamber and/or towards the outside. Preferably, the cover or layer is designed to distribute a force acting on the valve when the valve is actuated and/or to transmit said force over the wall in a distributed manner, preferably evenly and/or such that the valve seat is sealed evenly and/or completely by means of the wall. In this way, the risk of damage to the wall is reduced and/or reliable sealing is made possible or facilitated.

Preferably, the cover or layer is designed to reduce the force required to (completely) actuate the valve and/or to compensate for any asperities or surface roughness on the cartridge, in particular the wall, in particular such that the force required is reduced.

Particularly preferably, the cover or layer is designed to increase the restoring force of the wall and/or to move the wall away from the valve seat once actuation of the valve is complete, in particular such that the valve automatically reopens once actuation is complete.

Preferably, the valve seat comprises, preferably on an end face and/or on a side facing the wall, a first opening or inlet opening, through which a fluid can flow into the valve chamber. Advantageously, when the valve and/or the wall is actuated, the opening is thus directly and/or immediately closed, and therefore no fluid can flow into the valve chamber. Particularly preferably, the valve seat comprises a preferably circular contact surface or bearing surface for the wall on an end face and/or on a side facing the wall, the contact surface or bearing surface preferably delimiting or defining the first opening or the inlet of the valve at the sides. In particular, the valve seat comprises a preferably peripheral projection on an end face and/or on a side facing the wall. In this way, the distance between the valve seat and the wall is reduced when the valve is unactuated, and therefore the valve is closed even when the wall is slightly deflected. The term "cartridge" is preferably understood to mean a structural apparatus or unit designed to receive, to store, to physically, chemically and/or biologically treat and/or to measure a preferably biological sample. A cartridge within the meaning of the present invention preferably comprises a fluidic system or fluid system having a plurality of channels, cavities and/or valves for controlling the flow through the channels and/or cavities. In particular, within the meaning of the present invention, a cartridge is designed to be at least substantially planar, flat and/or card-like, in particular is designed as a fluidic card and/or is designed as a support and/or container for the sample that can be inserted and/or plugged into the proposed analysis device.

The term "analysis device" is preferably understood to mean a structural apparatus designed to chemically, biologically and/or physically test and/or analyse a sample or analysis sample or a component thereof, in particular in order for it to be possible to directly and/or indirectly detect or identify a disease and/or pathogen. An analysis device within the meaning of the present invention is in particular a portable or mobile device designed in particular to directly test and/or analyse the sample, in particular on site and/or in the vicinity of the sampling site and/or away from a central laboratory.

However, other structural solutions are also possible.

Fig. 2 is a highly schematic partial section through the cartridge 100 in the region of the receptacle or receiving cavity 104.

Preferably, the cartridge 100, in particular the support or main body 101 , comprises a depression 104H, in particular forming the receiving cavity 104, which is covered by the film or cover 102 in this case. Additionally or alternatively, the film or cover 102 forms the receiving cavity 104 and/or depression 104H, preferably so as to be raised from the support or main body 101 or the surface thereof. The receptacle or receiving cavity 104 preferably comprises a connection 104A for receiving the sample P. In particular, a transfer apparatus 320, in this case preferably comprising a connection 323, in particular a connecting tip, can be connected to the receptacle or receiving cavity 104 or the connection 104A thereof, as shown schematically in Fig. 2, in order to fill the receptacle or receiving cavity 104 with the sample P.

In the example shown, the receptacle or receiving cavity 104 preferably comprises a closure element 130 for this purpose, which in this case is designed in particular as a latched, screwed or hinged lid.

Once the sample P has been received, the transfer apparatus 320 is removed from the receptacle or receiving cavity 104 or the connection 104A and the receptacle or receiving cavity 104 or the connection 104A thereof is closed by the closure element 130.

The fluid system 103 is preferably connected to the receptacle or receiving cavity 104 and/or the depression 104H by means of a connection channel or outlet 104C for receiving and/or discharging the sample P, as shown schematically in Fig. 1 and 2, the fluid system 103 being shown only in part in Fig. 2.

Furthermore, the fluid system 103 is preferably connected to the receptacle or receiving cavity 104 or the depression 104H thereof via a ventilation channel or inlet 104B and/or flushing channel or intermediate connection 104D, such that the sample P or at least a component thereof can be conveyed out of the receptacle or re- ceiving cavity 104 or depression 104H, in particular via the channel or outlet 104C, in particular without a (relevant) vacuum developing in the receptacle or receiving cavity 104.

The analysis device 200 preferably comprises a retaining element 246, which is assigned to the receptacle or receiving cavity 104, connection 104A and/or closure element 130 in order to keep the receptacle or receiving cavity 104, the connection 104A thereof and/or the closure element 130 closed and/or to secure them in the closed position when the cartridge 100 is received, as shown merely schematically in Fig. 3. The analysis device 200 preferably comprises one or more sensors 206, in particular for monitoring or controlling the test sequence, as shown schematically in Fig. 3. For example, a liquid front or the presence of liquid in a channel or cavity can be detected, for example optically or capacitively, by means of a sensor 206. The sensors 206 may be provided in addition to or as an alternative to the sensors 1 16 arranged on the cartridge 100.

In the following, a preferred sequence of a test using the proposed cartridge 100 and/or the proposed analysis device 200 and/or analysis system 1 and/or in ac- cordance with the proposed method is explained in greater detail.

Preferably, a test is carried out on site, i.e. independently from a central laboratory or the like, for example by a veterinarian or another doctor. Preferably, the present invention is thus used as a point-of-care system.

A sample P is preferably received by the receptacle or receiving cavity 104 of the cartridge 100. For this purpose, the receptacle or receiving cavity 104 or the closure element 130 thereof is preferably first opened. The sample P is then preferably manually introduced or inserted into the receptacle or receiving cavity 104 or placed therein, in particular by means of the transfer apparatus 320.

Once the sample P has been received, the receptacle or receiving cavity 104 or the connection 104A thereof, as well as the vent 104E, if provided, are fluidically closed by the closure element 130, in particular in a liquid-tight and gas-tight manner.

The cartridge 100 is (then) preferably connected to the analysis device 200, in particular is inserted or slid into said analysis device 200.

Preferably, the cartridge 100 is moved towards the pump head 202B, or vice versa, in particular such that said pump head 202B rests on the cartridge 100, in particular on the pump chamber 1 12C and/or wall 1 12D, at least in part. In particular, the cartridge 100 and/or the pump head 202B is moved far enough that the pump head 202B is elastically deformed and/or is adapted at least in part to the surface of the cartridge 100 and/or to the pump chamber 1 12C. The pump is then activated and/or the pump head 202B is driven or rotated, in particular in order to start the test or analysis of the sample P.

Preferably, some or all of the actuation elements 205D of the actuators or actuation apparatuses 205 are simultaneously, previously or subsequently moved from the first position into the second position and/or are pressed against or into the cartridge 100 and/or the cartridge 100 is moved towards one or more actuation elements 205D, in particular in order to open and/or close the assigned valves 1 15.

Preferably, the first group 153 and the second group 154 are actuated from differ- ent sides 100A, 100B of the cartridge 100, preferably by means of the actuators 205 and/or actuation elements 205D.

Preferably, the first group 153 is actuated, in particular opened, from the front 100A and/or in the first actuation direction B2.

Particularly preferably, at least one valve 1 15 of the valves 1 15 and/or the first group 153 is irreversibly opened.

In particular, the storage cavity 108, measuring or metering cavity 105, mixing cavi- ty 107, treatment or reaction cavity 109 and/or collection cavity 1 1 1 is/are opened and/or fluidically connected to a preferably directly adjacent channel 1 14 and/or is/are interconnected, preferably in succession and/or simultaneously and/or in a predefined order, by actuating or opening the preferably upstream and/or downstream valves 1 15 in particular of the first group 153.

In particular, the storage cavity/cavities 108 or the reagent or reagents, in particular liquid reagent(s) F, therein is/are released, preferably simultaneously, by opening the first group 153 or the assigned valves 1 15, and/or is/are provided for reactions with the sample P or a component of the sample P.

Particularly preferably, a plurality of valves 1 15, in particular some or all of the valves 1 15 in the first group 153, are simultaneously actuated, in particular opened, by means of an assigned actuator 205 of the actuators 205 and/or by means of assigned actuation elements 205D.

Particularly preferably, the valves 1 15 of the first valve type 151 and/or in the first group 153 are actuated in such a way that the associated seal or separation elements 151 G are destroyed and in particular remain permanently open.

In particular, the actuation elements 205D penetrate the assigned through holes 151 E from the front 100A, preferably such that the valves 1 15 of the first valve type 151 and/or in the first group 153 are opened on the back 100B.

Preferably, the valves 1 15 of the second valve type 152 and/or in the second group 154 are previously, simultaneously or subsequently actuated, in particular closed and/or opened in the desired or required manner or order.

In particular, the valves 1 15 of the second valve type 152 and/or in the second group 154 are actuated, in particular closed, from the back 100B, preferably by elastic deformation or compression of the flexible wall 1 15D and/or 152D. Following or together with the actuation of a valve 1 15 or of the first or second group 153, 154 and/or together with the activation of the pump, the test on the sample P is carried out in the cartridge 100 in the analysis device 200, preferably at least largely in an automated manner or automatically or self-actingly. The sample P is removed from the receptacle or receiving cavity 104 or depression 104H at least in part, in this case via the connecting channel or outlet 104C.

In order to cause said sample P to be removed and/or to prevent negative pressure from building up in the receptacle or receiving cavity 104, a fluid, in particular air or another gas or a liquid, such as a flushing liquid or the like, is fed to the receptacle or receiving cavity 104, in particular via the ventilation channel or inlet 104B and/or flushing channel or intermediate connection 104D, preferably by means of the pump, the pump apparatus 1 12 and/or the pump drive 202. In order to convey the sample P out of the receptacle or receiving cavity 104, the pump or pump apparatus 1 12 can generate negative pressure on the outlet side and/or overpressure in the receptacle or receiving cavity 104 on the inlet side, in particular via the ventilation channel or inlet 104B and/or flushing channel or inter- mediate connection 104D. Here, if required, the relatively large collection cavity 1 1 1 can be used as a pressure storage means for applying pressure to the receptacle or receiving cavity 104 and/or for equalising the pressure. The sample P is treated, prepared and/or metered and/or added to or mixed with reagents, in particular liquid reagents F, in the desired or required manner in the cartridge 100.

For example, the sample P is first fed to the measuring or metering cavity 105 for metering, preferably by means of the pump, the pump apparatus 1 12 and/or the pump drive 202.

The sample P is then preferably fed to a mixing cavity 107 and mixed with a reagent or a plurality of reagents, in particular a liquid reagent F or a plurality of liquid reagents F, for example in order to dilute the sample P, to adjust the pH, to lyse cells and/or to carry out other reactions, preferably by means of the pump, the pump apparatus 1 12 and/or the pump drive 202.

The reagents may also be provided or introduced as dry reagents if required.

The sample P is then preferably fed to at least one treatment or reaction cavity 109, for example in order for a PCR or other treatment to be carried out therein, preferably by means of the pump, the pump apparatus 1 12 and/or the pump drive 202. Here too, corresponding reagents, in particular liquid reagents F, may again be added or mixed in if required.

The PCR or other treatment may take place or be carried out at specified temperatures. The cartridge 100, the analysis device 200 and/or the proposed analysis system 1 is preferably designed such that the desired temperatures or temperature profiles for the sample P are achieved, maintained or passed through in the respective cavities and channels. In particular, corresponding temperature control or regulation is provided or implemented.

The method sequence, in particular the flow and conveying of the liquids, the mix- ing and the like, is/are controlled by the analysis device 200 and/or the control apparatus 207, in particular by accordingly activating or actuating the pump drive 202 or pump apparatus 1 12 and the valves 1 15. The analysis device 200 and/or the control apparatus 207 thereof can detect liquid states, for example a liquid front or the presence of liquid, in particular by means of the sensors 1 16 and/or 206, and can accordingly take this into account for the control.

Additionally or alternatively, also optical detection or measurement can be carried out, for example for the presence of liquid, the fill level of a cavity or the like.

The collection cavity 1 1 1 is used in particular to receive excess or used liquids, such as the sample P, reagents F or the like. Alternatively or additionally, the collection cavity 1 1 1 is optionally also used for pressure equalisation, since, after the receptacle or receiving cavity 104 has been closed, a fluidically completely closed circuit is preferably formed on or in the cartridge 100. The collection cavity 1 1 1 preferably comprises a flexible or elastically deformable wall, which is in particular formed by the film or cover 102 or the like, in particular in order to make the above-mentioned pressure equalisation possible. However, other structural solutions are also possible. The prepared sample P or components thereof, for example amplified DNA sequences, is/are lastly fed to the sensor apparatus 1 13, preferably by means of the pump, the pump apparatus 1 12 and/or the pump drive 202.

Preferably, the sample P is then in particular electrochemically measured, for ex- ample for the presence of at least one desired target analyte.

The preferably electrical measurement is controlled by the analysis device 200 or the control apparatus 207 and/or the sensor apparatus 1 13. The test results or measurement results are in particular electrically transmitted to the analysis device 200 or the control apparatus 207 thereof, and are accordingly prepared, analysed, stored and/or displayed, in particular by the display apparatus 209.

After the test has been carried out, the cartridge 100 is removed from the analysis device 200 again and is preferably disposed of.

The fluid system 103 is preferably designed as a microfluidic system. The same preferably also applies to the cartridge 100, which is in particular designed as a microfluidic cartridge. In the present invention, the term "microfluidic" is preferably understood to mean volumes of less than 1 ml, particularly preferably less than 0.5 ml, in individual cavities or channels or in a plurality of or all of said cavities or channels.

Preferably, no external liquids have to be fed in or provided while the test is being carried out. This minimises the risk of inadvertent contamination of the surroundings or the analysis device 200. At the same time, the sensitivity to external disturbances is reduced, since no additional substances need to be introduced in addi- tion to the sample P.

Preferably, the storage cavities 108 are closed by mechanically actuated valves 1 15, and not by what are known as capillary stops or the like. This also increases the robustness of the cartridge 100 and maintains its functionality.

The cartridge 100 and/or the support or main body 101 is preferably produced in an injection-moulding process, particularly preferably from polypropylene, in particular with the depressions, which are preferably only made on one side and are intended to form the cavities and channels, preferably being covered by the film or cover 102 only on one side, or on both sides if required, and said cavities and channels being formed in a desired manner as a result. However, other structural solutions are also possible.

Particularly preferably, a plurality of or different closed (gas-tight) circuits are formed on or in the cartridge 100 for different fluids, liquids, reagents F and/or for the sample P, depending on the state of the valves 1 15 of the fluid system 103, for example a circuit for conveying the sample (receptacle or receiving cavity 104, connection channel or outlet 104C, cavity 105, channel 1 14, cavity 107, channel 1 14, pump apparatus 1 12, channel 1 14 and back to the receptacle or receiving cavity 104 via the ventilation channel or inlet 104B) and a circuit for conveying the reagents (a cavity 108, channel 1 14, cavity 107, channel 1 14, pump apparatus 1 12 and channel 1 14 back to the cavity 108).

A plurality or all of the circuits can preferably be operated by the same pump appa- ratus 1 12. One or more circuits are in particular formed by the fluid system 103 together with the receptacle or receiving cavity 104, in order to transfer the sample P from the receptacle or receiving cavity 104 into the fluid system 103. One or more circuits are preferably formed without the receptacle or receiving cavity 104, i.e. only in the fluid system 103.

The different circuits are used for example to convey the sample P, to treat the sample P with one or more reagents, in particular liquid reagents F, to feed the treated sample P to the sensor apparatus 1 13, to flush one or more cavities, or the like.

In particular, the present invention relates also to any one of the following aspects which can be realized independently or in any combination, also in combination with any aspects described above or in the claims:
