System for washing and inspecting medical equipment.

FIELD

The invention relates to a system for washing and inspecting medical equip- ment, to a method for controlling a system for washing and inspecting medical equipment, a computer readable medium to implement a method for control- ling a system for washing and inspecting medical equipment, and to a use of the system for washing and inspecting medical equipment.

BACKGROUND

Systems for washing and inspecting used medical equipment are widely known in hospital environments.

Used medical equipment in hospitals, clinics or the like have to be washed and inspected after a medical procedure before they can be used again.

The washing and inspection of medical equipment such as surgical equip- ment is typically done in a centralized system or facility within a hospital. Be- fore being washed, sterilized and packed to be reused, the medical equip- ment is typically manually pre-washed/ roughly washed and inspected by a staff member.

These systems usually comprise a washing table with a working position for a human operator, the used dirty medical equipment is placed in trays or con- tainers, and transported with trolleys to the washing table, to be washed and inspected. However, many of the steps/processes in these systems are rather repetitive and inefficient. Staff members are monitoring or performing many of the pro- cesses manually, making them time- and labor-consuming.

Another problem arising is that many of the processes may stand still for a period of time whereby the stations are in standby.

A solution to that may be to automate some processes performed in the washing and inspection stations, whereby the efficiency of such systems may be improved.

An example of a system for washing and inspecting medical equipment where automated processes are implemented is disclosed in WO2017077073. The station comprises a dirty area and a clean area, a washing table with two washing sides, washers, and an unmanned vehicle for loading, unloading, and transporting of medical equipment in baskets, where the unmanned vehi- cle can adjust in the vertical and horizontal direction. The station further corn- prises control devices for communication with the unmanned vehicles. The unmanned vehicles can be monitored to travel to specific pick-up points at the washing tables.

Nevertheless, many of the processes involved in the washing and inspection of medical equipment can still be improved in the above system.

Thus, it remains a problem to provide a more efficient system for washing and inspecting medical equipment. SUMMARY

According to a first aspect, the invention relates to a system for washing and inspecting medical equipment comprising:

• a washing station for washing and inspecting medical equipment,

the washing station comprising a first working position for a human op- erator

• a transport vehicle for transporting medical equipment to the washing station,

• a control unit

• a receiving element arranged in connection with the washing station, the receiving element being configured to receive a container compris- ing medical equipment transported by the transport vehicle to be washed and inspected, the receiving element being movable between a receiving position at a first height and a working position at a second height, wherein the receiving element is configured to receive the con- tainer at the receiving positon and subsequently move to the working position wherein the control unit is configured to receive first user information related to the human operator working at the first working position and in response thereto to control the system based on the first user information.

By having a control unit configured to control the system based on first user information, the system may function in a more efficient and automated way.

The medical equipment may be stored in a centralized storage before being transported to the system for washing and inspection. The medical equipment may be sorted at the storage. The storage may be controlled by the system. The medical equipment may be transported from the storage to the system by a transport vehicle of the system. The medical equipment may be any type of equipment used in relation with a hospital or clinic, that prior to be reused need to be washed and inspected e.g. surgical instruments. The medical equiment may be transported to the system in a container. The medical equipment may be sorted before being put in a container.

The washing station may comprise e.g. a table, a sink, a washing and flush- ing arrangement, an inspection arrangement as a magnifying glass, a blowing or air gun, a water gun, and/or a trash receptacle.

The table of the washing station may be height adjustable. The control unit may control the height of the table based on the first user information.

The transport vehicle may be an automated or semi-automated vehicle. The transport vehicle may comprise a drive mechanism and travelling means such as wheels or chain-wheels. The transport vehicle may comprise navigation means such as sensors and/or cameras for navigation in order to orientate itself and such that it doesn’t collide with any other object. The transport vehi- cle may be guided with guiding means such as floor stripes e.g. colored stripes or magnetic stripes. The guiding means may also be vision, or laser means.

The transport vehicle may follow markers or wires in the floor, lasers or any other guiding means for navigation. The transport vehicle may also be fully configured to travel without any guiding means e.g. by having a pre- programmed travelling path or by having a map of the navigation area for de- termining the travelling path based on the map and the navigation means.

The transport vehicle may comprise a motorized roller, belt, or chain conveyor for delivering medical equipment.

The control unit may be operatively connected to the different elements of the system, e.g. the transport vehicle, the washing station, the receiving element, or any other element of the system. The control unit may be wirelessly con- nected to the different elements of the system. Furthermore, the control unit may be connected to an external network, where the network may e.g. be a network within a hospital or a global network such as the internet.

The control unit may be configured to receive an input e.g. the first user in- formation. The control unit may be further configured to send an output e.g. a control signal to the different elements of the system. The first user information may be data pre-stored on a data storage unit. Alternatively the first user information may be received at the control unit e.g. from a sensor or a camera.

The control unit may have access to the storage database to access the first user information.

By having a receiving element in connection with the washing station, the re- ceiving element being movable between a receiving position at a first height and a working position at a second height, wherein the receiving element is configured to receive a container at the receiving position and subsequently move to the working position, the receiving element may be adjusted to the height of the transport vehicle. The height of the transport vehicle may there- fore be lowered, whereby a simpler and more stable transport vehicle may be provided. The transport vehicle may furthermore be provided without height adjustment capabilities. A further advantage of having a receiving element according to the invention is that the working area around the user working at the washing station is kept more secure, because the transport vehicle is kept substantially away from the user. This is in contrast to known systems, where transport vehicles drive up to the washing station and may interfere with a user, and may collide with the user and possibly injure said user. The receiv- ing element provides therefore a much more secure system by keeping the elements of the system at a substantially constant distance from the user, which thereby do not have to worry about e.g. the transport vehicle driving around him.

The receiving element may comprise a motorized roller, belt, or chain con- veyor for receiving a container with medical equipment from a transport vehi- cle and/or for delivering an empty container to a transport vehicle. A container may be transferred e.g. by the conveyor of the transport vehicle, by the con- veyor of the receiving element, or by the combination of the conveyor of the transport vehicle and the conveyor of the receiving element. The receiving element may be able to communicate with the washing station and the transport vehicle independently from the control unit. This communi- cation may be done wirelessly.

The receiving positon may be at a constant height i.e. if the transport vehicle has a constant height.

The receiving element may also deliver a container to a transport vehicle when the container is empty.

The receiving element may further be movable in the horizontal direction e.g. to compensate for a spacing between the receiving element and the transport vehicle.

In some embodiments the system comprises a user input unit operatively connectable to the control unit, and the control unit is configured to receive control signals from the user input unit and control said system based on said control signals.

A human operator working at the first working position may indicate at the user input unit when he/she has finished washing and inspecting medical equipment. Further a human operator may indicate at the user input unit when he/she is ready to receive medical equipment to be washed and in- spected. The human operator may also indicate the working position of the receiving element at the user input unit.

The user input unit may e.g. have a keyboard, a touch screen or the like, whereby the human operator at the first working position may receive instruc- tions, give instructions, and/or provide feedback to the system.

In some embodiments the control unit is configured to set the working position of the receiving element.

In some embodiments the control unit is configured to set the working position of the receiving element based on the first user information.

By setting the working position of the receiving element based on the first us- er information, it may be possible to customize the working position of the receiving element to e.g. the height of the user in order to provide a more comfortable working position for the user. A more comfortable working posi- tion for the user may avoid the user of getting back pain, and it may ensure that the user has the container and its content within reach.

In some embodiments the control unit is configured to set the working position of the receiving element based on the type of medical equipment in the con- tainer.

In some situations, the medical equipment and/or the container may have dimensions that exceed e.g. the working position height, and it may therefore be advantageous to set the working position of the receiving element based on the type of medical equipment in the container. The user may thereby have an improved working position for medical equipment and/or containers having e.g. an unusual and cumbersome size e.g. the working position may be lower for long elongated types of medical equipment than for shorter types of medical equipment.

In some embodiments the control unit has access to a plurality of user profiles for human operators of the system, and the control unit is configured to re- ceive first user information related to the human operator working at the first working position by receiving a user profile related to said human operator working at the first working position.

The control unit may therefore control the system based on the user profile of the human operator working at the first working position. The control unit may thereby control the system in an efficient and automatic way e.g. by transport- ing medical equipment matching to a user profile or by adjusting the height of the table based on the user profile.

A user profile for a human operator may comprise information e.g. the height, the age, the gender, the position, the experience, and/or the medical equip- ment preferences of the human operator. A user profile of a human operator may be updated with new information related to the human operator. The up- date of a user profile may be performed automatically by the control unit or manually by a human operator.

The human operator may e.g. login at the user input unit when starting to work at the first working position and logout when finishing to work.

In some embodiments the system is configured to wash and inspect a plurali ty of different classes of medical equipment, each class requires a specific user authorization to inspect and wash medical equipment of said class, each of the plurality of user profiles specifies the user authorizations of the respec- tive human operator, wherein the control unit is configured to control the sys- tem so that the transport vehicle only transports to the washing station medi- cal equipment of classes which the human operator working at the first work- ing position has user authorization for.

By only transporting to the washing station medical equipment of classes that the human operator working at the first working position has user authoriza- tion for, the human operator does not have to assess or decide which medical equipment he/she has user authorization to wash and inspect. The system may therefore be further automated, and be able to function more inde- pendently. Furthermore, the system may not be dependent on an order or a monitoring from a human operator or a staff member, to choose or transport medical equipment to be washed and inspected by a human operator working at the first working position. Additionally, errors in the washing and inspection due to human operators lacking user authorization for washing and inspecting certain classes of medical equipment may be avoided. This may provide a better quality for the washing and inspection.

A class of medical equipment may comprise or consist of different types of medical equipment e.g. medical equipment of different sizes or medical equipment of substantially the same size but having other different character- istics. A class of medical equipment may consist of a specific type of medical equipment e.g. surgical equipment of a specific kind, such as cutters, retrac- tors, or graspers. Different characteristics may be medical equipment of a different kind.

As an example, a class of medical equipment may comprise or consist of substantially small medical equipment of mixed kind, but may for example also comprise or consist of surgical equipment which may have both substan- tially small and substantially big equipment. The control unit may be config- ured to control the system such that the transport vehicle transports medical equipment of different classes to the washing station, as long as the human operator working at the first working position has user authorization to wash and inspect the medical equipment.

In some embodiments each user profile of the plurality of user profiles corn- prises information about working preferences of the human operators.

In some embodiments the working preferences comprise one or more items selected from the list comprising:

working height preferences and/or medical equipment preferences.

By having information about the working preferences of the human operators, the control unit may be configured to control the system such that the washing station may be adjusted based on the working preferences of the human operator working at the first working position. Further, the control unit may control the system such that the transport vehicle transports medical equipment based on the medical equipment preferences of the human operator working at the first working position to the washing station. The washing station may be pre-adjusted for a human operator and when a new human operator is to work at the washing station the control unit may change the adjustment of the washing station and the medical equipment transported by the transport vehicle to the washing station in an automatic way. The system may therefore be more efficient and function in a more automatic way without having to perform manual adjustment and/or receive orders from a human operator. In some embodiments the control unit sets the working position of the receiv- ing element based on the user profile of the user.

In some embodiments the receiving element has a first and a second area, where the first area is configured to receive a container with medical equip- ment transported by the transport vehicle to be washed and inspected and the second area is configured to deliver an empty container to the transport vehicle.

By having a receiving element with a first and a second area, the transport vehicle may transport to the washing station, the next container with medical equipment to be washed and inspected before the previous container has been emptied. The human operator may therefore when having emptied a container with medical equipment to be washed and inspected, immediately pick from the next container with medical equipment to be washed and in- spected without having to wait on the transport vehicle removing the empty container and delivering the next container. The transport vehicle may there- by also remove the empty container while the human operator has started with the next container and so on. The first and second area may both be configured to receive and deliver containers. The first and the second area may be configured to transfer containers to each other if one of the areas is empty of containers. The first and the second area may both be configured to receive containers with medical equipment from the transport vehicle and may both be configured to deliver empty containers to the transport vehicle.

The containers comprising medical equipment may be of different kind e.g. have different sizes i.e. depending on the classes of medical equipment or the type of medical equipment. The containers used with the receiving element and the containers used with the outgoing element may be different containers.

In some embodiments the system further comprises an outgoing element ar- ranged in connection with the washing station, the outgoing element being configured to deliver a container comprising medical equipment that have been washed and inspected, to the transport vehicle, the outgoing element being adjustable in height, and wherein the control unit is further configured to control the outgoing element, the outgoing element being movable between a working position at a first height and an outgoing position at a second height, said working position being adjustable in height, and wherein the outgoing element is configured to be at the working position while the human operator is washing and inspecting the medical equipment, and subsequently move to the outgoing position to deliver the container to the transport vehicle.

By having an outgoing element in connection with the washing station, the outgoing element being adjustable in height, the outgoing element may be adjusted to the height of the transport vehicle. The height of the transport ve- hicle may therefore be constant, whereby a simpler transport vehicle may be provided. The outgoing element may comprise a roller, belt, or chain convey- or for delivering a container with washed and inspected medical equipment to a transport vehicle and/or for receiving an empty container from a transport vehicle. A container may be transferred by the conveyor of the outgoing ele- ment, the conveyor of the transport vehicle or by the combination of the con- veyor of the transport vehicle and the conveyor of the outgoing element.

The outgoing element may be able to communicate with the washing station and the transport vehicle independently from the control unit. This communi- cation may be done wirelessly.

The outgoing positon may be at a constant height i.e. if the transport vehicle has a constant height.

The outgoing element may also deliver a container to a transport vehicle when the container is empty.

The outgoing element may further be movable in the horizontal direction e.g. to compensate for a spacing between the outgoing element and the transport vehicle. The transport vehicles transporting to and from the receiving element and to and from the outgoing element may be different transport vehicles e.g. dirty transport vehicles for the receiving element and clean transport vehicles for the outgoing element.

In some embodiments the working position of the outgoing element is set by the control unit based on the first user information.

The working position may e.g. be set based on the, user profiles, the working preferences, the class of medical equipment, and/or the medical equipment in a container. The working position of the receiving element and the outgoing element may be the same but may also be different. By having the working position set by the control unit based on the first user information, the human operator working at the first working position may be put in the most optimal conditions to perform the washing and inspection of medical equipment, whereby the efficiency of the system may be improved.

In some embodiments the control unit is configured to control the washing station, the transport vehicle, the receiving element, and/or the outgoing ele- ment based on the first user information.

In some embodiments the control unit has access to first user information such as scheduling information of the human operators of said system, and wherein the control unit is configured to control the system so that the transport vehicle transports medical equipment to the washing station based on the scheduling information of the human operators.

The control unit may be configured to schedule the washing and inspection of a class or type of medical equipment based on the scheduling information of the human operators. For example, a human operator being the only one hav- ing user authorization for a class of medical equipment may be away or occu- pied one week, and in response thereto the control unit may prioritize to transport the class or type of medical equipment to that specific human opera- tor before said week. The washing and inspection of medical equipment may therefore be optimized based on the scheduling information of the human op- erators of the system.

The scheduling information of the human operators may e.g. be calendars comprising information about the tasks, the working hours, the shifts and/or the vacations.

In some embodiments the first user information comprises data log infor- mation of events in the system, such as data log information related to the washing and the inspection.

In some embodiments the control unit is configured to control the system based on the data log information so that the transport vehicle transports medical equipment to the washing station based on the data log information of events in the system.

The data log information may e.g. be washing and inspection times of a class or a type of medical equipment or of the medical equipment in a container, by a human operator.

The control unit may e.g. be configured to optimize the washing and inspection times of the system, so that the transport vehicle transports a class or a type of medical equipment to the human operator having the fastest washing and inspection times for said class or type of medical equipment.

In some embodiments the transport vehicle is selected from the following types of vehicles:

an AGV (automated guided vehicle), AGC (automated guided cart), LGV (la- ser guided vehicle), an UGV (unmanned ground vehicle), and/or a drone.
