BODY BAG ARRANGEMENT AND VALVE THEREFOR

Field of the Invention

[1 ] The present invention relates to bag arrangement, and in particular to a bag arrangement for storage and transport of dead bodies.

[2] The invention has been developed primarily for use in/with human bodies and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.

Background of the Invention

[3] Many large-scale disasters, such as earthquakes, tsunamis or cyclones result in large-scale loss of both human and animal lives. In the immediate aftermath of such disasters, resources such as electricity cannot be relied upon. Places like morgues or hospitals may be overwhelmed, with priority being given to doing what can be done for those still alive. Further, removal of dead bodies may not be possible due to blockages of roads.

[4] Further, in disaster zones, bodies may be laid out for convenient identification by families of the deceased. Any shelter that is available may be reserved for makeshift hospitals, or refuges for displaced living people.

[5] For this reason, many dead bodies may often be wrapped in stored in unsheltered areas, subject to environmental conditions. This can lead to unhygienic and unsafe conditions in which diseases can develop and spread. Furthermore, once natural decay sets in, the smell emanating from such bodies can be bad.

[6] The present invention seeks to provide a bag, which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.

[7] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.

Description of Embodiments

[149] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.

[150] A bag arrangement according to a first aspect of the invention is generally indicated by the numeral 1000.

[151 ] In one embodiment now described, there is provided a bag arrangement 1000 suitable for the storage and/or transport of deceased human bodies. In a preferred embodiment, the bag arrangement will be suitable for the storage and/or transport of adult human bodies, however it is also envisaged that the bag arrangement 1000 may be suitable for storage and/or transport of smaller bodies, such as children, infants or animals.

[152] In the embodiment shown, the bag arrangement 1000 comprises a flexible bag 1 100, a sealing arrangement 1200 and an extraction passage 1600 through which air in the bag can be evacuated.

[153] In preferred embodiments shown in figures 4 and 11 , the extraction passage 1600 is defined by an extraction valve 1300 in order to ensure that area evacuated from the flexible bag 1 100 does not return into the flexible bag via the extraction passage 1600. In the embodiment shown the extraction valve 1300 comprises a one way valve arrangement 1305 comprising a valve body 1360, a closure 1340 and a bias in the form of a spring 1330. The closure 1340 is biased by spring 1330 towards a sealing seat 1342 defined by the valve body 1360, to seal the extraction passage 1600. As a vacuum is created on the outside of the valve, the closure 1340 is moved away from the sealing seat 1342 against the bias of a spring 1330. Once the vacuum is removed from outside the valve, the spring 1330 will move the closure 1340 back into position against the sealing seat 1342.

[154] In the embodiment shown in figure 11 , the extraction valve 1300 comprises a nozzle portion 1370 configured for engagement with a vacuum extraction device (not shown), and a filter portion 1380 for at least partially containing the filter arrangement 1320. The nozzle portion 1370 and the filter portion 1380 are preferably configured to sealingly engage with each other. In this regard, a seal 1395 is provided for sealing the interface between the nozzle portion 1370 and the filter portion 1380. [155] A filter arrangement 1320 is contained within the filter portion 1380, and is preferably located inside the flexible bag 1 100.

[156] The nozzle portion 1370 is preferably configured for being welded to the flexible bag 1 100, although it is envisaged that the filter portion 1380 could also or alternately be welded to the flexible bag 1 100.

[157] Engaging formations 1350 in the form of snap fit type formations are provided for engaging the nozzle portion 1370 with the filter portion 1380, however in alternative embodiments (not shown) it is envisaged that the engaging formations 1350 could be a wide variety of shapes and configurations, including a bayonet -type arrangement, a threaded formation, or the like. It is also envisaged that the nozzle portion 1370 may be removably engageable with the filter portion 1380, however this is not preferred in the interests of safety.

[158] As shown in figure 11 , the one way valve arrangement 1305 is disposed within the nozzle portion 1380, although this need not necessarily be the case.

[159] The valve closure 1340 shown in figure 11 is preferably composed of a resilient material such as silicone, and in use when suction is applied to the nozzle portion by a vacuum extraction device, the valve closure 1340 will be moved to its open position away from the sealing seat 1342 in order to allow fluids to move through the extraction passage 1600. In the embodiment of the extraction valve 1300 shown in figure 11 , no spring or other biasing formation is provided. Once sufficient fluid has been removed from within the flexible bag 1 100, a negative pressure will exist within the flexible bag. This will have the effect of pulling the valve closure 1340 back against the sealing seat 1342 to prevent ingress of air into the flexible bag 1 100.

[160] In addition, the extraction valve 1300 comprises a valve cap 1390 configured for closing the flow of fluid through the extraction passage 1600. The valve cap 1390 is preferably used to ensure that the extraction valve 1300 remain is closed once the flexible bag 1 100 is evacuated, as this may result in the unwanted spread of bacteria and/or other pathogens. In this regard, it is envisaged that in another embodiment (not shown) the extraction valve 1300 can include locking formations (not shown), such as a ratchet type formation, for locking the valve cap 1390 in place and preventing its removal once it has been applied to the nozzle portion 1382 closed the extraction passage 1600.

[161 ] In the embodiment shown in figure 1 1 , the valve cap 1390 serves to push the closure 1340 against the sealing seat 1342 when it has been applied to the nozzle portion 1382 close the extraction passage 1600. This has the additional benefit of sealing the extraction passage 1600 securely.

[162] In one embodiment (not shown) the valve cap is tethered to the valve body 1360 by a tether (not shown).

[163] The flexible bag 1 100 defines a bag opening 1 1 10. The bag opening 1 1 10 is configured for receiving a body through the bag opening, so that the body can be fully encapsulated by the flexible bag 1 100.

[164] The flexible bag 1 100 further preferably comprises a rectangular front layer 1 140 and a rectangular back layer 1 150, that are preferably attached to each other, either by being integrally formed with each other, or by being sealed to each other by a sealing process, such as heat welding, ultrasonic welding or the like.

[165] The front layer is further comprised of two flap portions 1 142, which are separable from each other (as indicated by arrow A in figure 3) to create the bag opening 1 1 10. The sealing arrangement 1200 is configured for engaging the flap portions with each other to move the flexible bag 1 100 between an open configuration and a closed configuration.

[166] The sealing arrangement 1200 is preferably in the form of an elongate plastic zipper arrangement 1210 comprising a pair of beads that engage with each other along their length, such as those commonly known under the trade name Ziploc®, or a similar sealing arrangement 1200. In one embodiment, the zipper arrangement 1210 can preferably be composed of plastic, and comprises a first engaging bead 1212a associated with a first flap portion 1 142 a and a second engaging bead 1212b associated with a second flap portion 1 142b. The first engaging bead 1212a and the second engaging bead 1212b can be moved between an engaged configuration and a disengaged configuration, preferably by a bead engaging formation 1214 that is configured to draw the first engaging bead and second engaging beads 1212 a&b towards each other to engage with each other in a sealing fashion.

[167] In another preferred embodiment, the zipper arrangement 1210 is a watertight zipper arrangement such as one of those sold for use in industrial protective clothing or dry suits by Dynat™,. In such an arrangement, the zipper arrangement 1200 comprises two sets of interengaging zip teeth 1216 that are configured to engage with each other. The sets of interengaging zip teeth 1216 are drawn towards each other and engaged with each other by a zipper pull 1218. Each of the sets of zip teeth 1216 is associated with a sealing lining 1220, which are configured so that engagement of the sets of zip teeth 1216 with each other causes the sealing linings 1222 abut with, and seal against, each other. The abutment of the sealing linings when the sets of zip teeth 1216 engage with each other seals the first flap arrangement to the second flap arrangement for encapsulating a body in operation.

[168] In either of the embodiments of the sealing arrangement 1200 described above, it is envisaged that the zip arrangement 1210 further comprises complementary sealing engaging formations 1222 as shown in figure 5 that are disposed towards at least one end of the zip arrangement 1210, and preferably at both ends.

[169] The complementary sealing engaging formations 1222 are preferably in the form of a set complementary of castellated formations that are configured to engage with each other to act as a type of labyrinth seal to seal one or both of the ends of the zip arrangement 1210 as the zip arrangement 1210 is moved to its engaged configuration.

[170] In one preferred embodiment as shown in figure 6, the sealing arrangement 1200 can include a locking formation 1230, for example in the form of a loop moulded into an end of the sealing arrangement 1200 that allows for the zipper pull 1218 or the bead engaging formation 1214 to be secured to it, for example by a cable tie 5000 or the like, to ensure that the sealing arrangement 1200 remains in its engaged configuration. Such a feature would be critical where, for example, bodies of victims of exceptionally pathogenic diseases were being stored in the bag arrangement 1000.

[171 ] The sealing arrangement 1200 as shown in figures 1 - 3 is configurable between a disengaged configuration in which the flap portions 1 142 movable away from each other and in which a body is placeable into or onto the flexible bag; and a closed configuration in which the flap portions 1 142 are engaged with each other to enclose a body in the flexible bag 1 100 in operation.

[172] When the sealing arrangement 1200 is in its engaged configuration, the first engaging bead 1212a and the second engaging bead 1212b are in their engaged configuration substantially along the full length of the sealing arrangement 1200.

[173] When the sealing arrangement 1200 is in its disengaged configuration, the first engaging bead 1212a and the second engaging bead 1212b will be in their disengaged configuration substantially along the full length of the sealing arrangement 1200, allowing sufficient space for the placement within the flexible bag 1 100 of a deceased body. [174] Further, the flap portions 1 142 of the flexible bag 1 100 are configurable in an open figuration corresponding to the open configuration of the sealing arrangement 1200, and a closed configuration corresponding to the close configuration of the sealing arrangement.

[175] In this way, the flexible bag can be configured in an open configuration, and a deceased body can be placed within the flexible bag 1 100. Subsequent to this, the flexible bag can be configured in a closed configuration, with the sealing arrangement sealing the bag opening 1 100 to encapsulate the body.

[176] As shown in figure 4, the bag arrangement 1000 comprises a fitting nozzle 1310, which is preferably co-located with the extraction valve 1300 and the extraction passage 1600. The fitting nozzle 1310 is configured for sealing engagement with a vacuum extraction device (not shown).

[177] Also preferably co-located with the extraction valve 1300 and the fitting nozzle 1310 is a filter arrangement 1320. The filter arrangement 1320 is configured for filtering air being evacuated from the flexible bag 1 100 by the vacuum extraction device, and to this end, the filter arrangement 1320 is preferably configured for filtering microbes, such as bacteria and viruses, from the air as it is evacuated or extracted from the flexible bag 1 100. In other embodiments, it is envisaged that the filter arrangement 1320 may be configured for filtering particle small enough to prevent smells from escaping the flexible bag 1 100.

[178] It is envisaged that the vacuum extraction device can be of a wide variety of configurations and work on a wide variety of principles. In one embodiment, for example the vacuum extraction device could be a normal vacuum cleaner found in homes. This would ensure the increased availability of a suitable vacuum extraction device in the event of a disaster occurring.

[179] In another embodiment (not shown), it is envisaged that the vacuum extraction device could be in the nature of a foot pump or hand pump, or be a purpose-built impeller arrangement. It is further envisaged that the vacuum extraction device could be powered electrically via an electrical motor, for example from a generator, a power outlet or stored electric power pack such as a battery, or by a prime mover such as an internal combustion engine. It is further envisaged that the vacuum extraction device could include its own filter arrangement having a configuration similar to the filter arrangement 1320 described herein.

[180] In order to further reduce the spread of diseases and/or smells, the bag arrangement 1000 further comprises an antibacterial lining 1 120, preferably on the inside of the flexible bag. It is envisaged that the antibacterial lining 1 120 can be coated on an inner surface of the flexible bag 1 100, or can be an additional inner layer of the flexible bag. To this end, it is envisaged that the flexible bag 1 100 can be comprised of multiple layers of different materials. As an example, and outer layer of the flexible bag can be composed of woven polyethylene or another suitably strong material, while an inner layer can be a waterproof and/or airtight flexible plastic material, which can in addition have antiseptic or antibacterial properties.

[181 ] In another embodiment, it is envisaged that the bag arrangement can comprise, or be configured for receiving a quantity of embalming agent (not shown), for the purposes of slowing or preventing rotting of the body. To this end, an inlet (not shown) can be provided specifically for this purpose, or alternatively the embalming agent may be introduced into the bag 1 100 via the bag opening 1 1 10.

[182] In the embodiment shown in the figure, the bag arrangement 1000 further comprises a moisture absorbent layer located on the back layer 1 150 of the flexible bag 1 100. The moisture absorbent layer is preferably composed of silica crystals and/or silica gel, although it is envisaged that it could be composed of any suitable material that is effective in absorbing excess moisture. It is unlikely that any such layer will be able to absorb all of the liquid in a human body, but it is anticipated that it may assist in restricting the onset of rotting for a longer time period.

[183] In order to assist in the identification of bodies, it is envisaged that the front layer 1 140, or at least a portion of it, for example a viewing window 1 190, will be composed of a transparent material. If a window portion is provided, it is envisaged that the window portion will be provided at or towards an end of the flexible bag that would allow identification of the body by viewing its face. It is envisaged that this feature will allow bodies to be identified without having to open the sealing arrangement, which could then necessitate the re-evacuation of air from the flexible bag 1 100.

[184] In the embodiment shown in the figures, the bag arrangement 1000 further comprises a covering flap 1400 configured for covering the front layer of the flexible bag. The covering flap 1400 is for preserving the dignity of the bodies within the flexible bag 1 100, which may be visible through the front layer 1 140.

[185] The covering flap 1400 is movable between a covering position in which the front layer 1 140 of the flexible bag 1 100 is substantially covered to prevent the contents of the flexible bag 1 100 being viewed, and a displaying position in which the front layer 1 140 of the flexible bag is clearly visible. The covering flap 1400 is preferably composed of an opaque flexible material, such as woven polypropylene.

[186] In the embodiments shown, the bag arrangement 1000 includes engaging formations 1410 for engaging the covering flap to hold it in place in its covering position. It is envisaged that the engaging formations will comprise complementary hook formations and loop formations (not shown), such as those sold under the trade name Velcro®, wherein one selected from the hook formations and the loop formations will be attached to an internal face of the covering flap 1400, and the other one selected from the hook formations and the loop formations will be attached to either an outer face of the front layer 1 140, or an outer face of the back layer 1 150.

[187] In order to facilitate the moving of bodies, which is likely a requirement where such bodies are being processed at a disaster zone, the bag arrangement 1000 is provided with slinging formations 1500, which are configured for facilitating the lifting of the bag. In one preferred embodiment, the slinging formations comprise strong flexible loops 1510 that are arranged at regular intervals along the length of the flexible bag 1 100. It is envisaged that such loops 1510 will be composed of a strong, cheap material such as woven polyethylene plastic, and each loop 1510 will be dimensioned to receive a sturdy pole 5000 therethrough, to allow multiple carriers to lift a pole 5000 extending along the length of, and on either side of the bag arrangement 1000. In another embodiment (not shown) it is envisaged that the slinging formations may be configured to allow for movement of bodies by, for example, truck mounted cranes, pulley systems, or the like. This is advantageous where the availability of able bodied persons for picking up and moving dead bodies is low in disaster areas.

[188] It is envisaged that once a body has been received within the flexible bag 1 100, and the sealing arrangement 1200 moved to its closed configuration, the air within the flexible bag 1 100 can be evacuated by engaging a vacuum extraction device with the fitting nozzle 1310, and switched on in order to extract air from within the flexible bag. Air extracted from inside the flexible bag 1 100 via the extraction passage and through the extraction valve 1300 is prevented from flowing back into the flexible bag. The flexible bag 1 100 will be sucked up against the body, creating a more rigid package than if the body was lying in an un- evacuated bag. This aspect, together with the provision of the slinging formations 1500 will facilitate handling of bodies. [189] In the embodiments shown in figures 5 - 8, the flexible bag 1 100 comprises a first flap arrangement 1 160 and a second flap arrangement 1 170 connected to each other.

[190] The first flap arrangement 1 160 and the second flap arrangement 1 170 are movable between an open configuration as shown in figure 8, in which a body is able to be placed on one or more selected from the first flap arrangement and the second flap arrangement, and a closed configuration as shown in figure 7 in which the body is enclosed or encloseable, preferably in a sealed manner.

[191 ] As may be seen in figure 8, the first flap arrangement 1 160 and the second flap arrangement 1 170 are configured so that when the first flap arrangement 1 160 and the second flap arrangement 1 170 are in their open configuration, each of them forms a shallow container suitable for holding bodily fluids to prevent the bodily fluids from running off of the bag arrangement 1000.

[192] In the embodiments of the bag arrangement 1000 shown in figures 5 - 8, the first flap arrangement 1 160 is defined by a front layer 1 162 and a side face 1 164 of flexible material, while the second flap arrangement 1 170 is defined by a back layer 1 172 and a side face 1 174 of flexible material. The side faces 1 164, 1 174 form a container lip that prevents bodily fluids from running off the first flap arrangement and the second flap arrangement when they are in their open configuration.

[193] It is been found through investigation that during movement of a body on to prior art body bags, that the leakage of bodily fluids from the body onto an exterior surface of the body bags may then require that the body bag be inserted into another body bag in order to increase hygiene and prevent the spread of disease. This would be especially important if the body was a victim of exceptionally pathogenic disease. Naturally, the re-bagging or double bagging of bodies would require additional manpower and time, and is not desirable.

[194] By having the first flap arrangement 1 160 and the second flap arrangement 1 170 in a configuration that acts as a shallow container, to hold bodily fluids and prevent their run-off, this increases the usability of the bag arrangement 1000.

[195] In the embodiments of the bag arrangement 1000 shown in figures 7 and 8, the bag arrangement 1000 is substantially rectangular, with the side layers 1 164, 1 174 extending between the front layer 1 162 and the back layer 1 172 along at least three edges of the rectangular shape. [196] The front layer 1 162 and the back layer 1 172 are preferably attached to each other along at least one edge to allow for pivotally movement of the front layer 1 162 relative to the back layer 1 172.

[197] When the first flap arrangement 1 160 and the second flap arrangement 1 170 are in their closed configuration, adjacent edges of the side faces 1 164 and 1 174 are sealable to each other by a sealing arrangement 1200, preferably in the form of a zipper arrangement 1210 as shown in figures 5 and 6 and as described above.

[198] This particular configuration for the first flap arrangement 1 160 and the second flap arrangement 1 170 is advantageous in that it allows the zipper arrangement 1210 to be utilised such that it is only bent in a plane that is at right angles to a plane extending between the teeth or beading of the zipper arrangement. In this way, accidental opening of the sealing arrangement, or the exertion of forces on the sealing arrangement 1200 in undesirable directions that may result in the opening of the sealing arrangement is reduced.

[199] Also, as described above, the zipper arrangement 1210 is movable between an engaged configuration in which the first flap arrangement and second flap arrangement are movable to their open configuration, and a disengaged configuration in which the first flap arrangement 1 160 and the second flap arrangement 1 170 are sealed to each other.
