Description

Technical Field

[0001] The present application relates to the technical field of waste liquid treatment, and in particular to a portable waste liquid collection bag. Background Art

[0002] During surgery or rehabilitation treatment in a hospital, a large amount of waste fluid such as blood and tissue fluid will be generated. A waste liquid collection device is needed to recycle these waste fluids for centralized treatment. The use of a waste liquid collection device helps reduce cross-infection and the spread of infectious diseases, and minimizes harm to patients' families and medical staff, and endangers public health safety.

[0003] A portable waste liquid collection bag is designed in the related art, and its structure mainly includes a soft bag body, on which a liquid inlet pipe and a liquid outlet pipe are connected. When in use, the liquid inlet pipe is connected to a catheter on the patient's body, and the waste blood or tissue fluid is absorbed into the bag body through the liquid inlet pipe by a portable negative pressure device.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: after blood or tissue fluid enters the bag, due to the fluidity and gravity of the liquid, the waste liquid will concentrate at the lowest point in the bag, and the outer wall of the bag is easily pulled by the waste liquid and deformed, making it difficult to fill the bag with liquid, which can easily cause waste of space inside the bag and low bag utilization. Summary of the invention

[0005] In order to improve the utilization rate of the bag body and reduce the waste of the internal space of the bag body, the present application provides a portable waste liquid collection bag.

[0006] The portable waste liquid collection bag provided in this application adopts the following technical solution: A portable waste liquid collection bag comprises a connector, on which a bag body is fixedly arranged, and the bag body is connected to two conduits, one of which is used to guide waste liquid to flow into the bag body, and the other is used to guide waste liquid to flow out of the bag body, one side wall of the bag body is a first side wall, and the other side wall of the bag body is a second side wall, a protective body is arranged at the center of the inner side of the first side wall, the edge of the protective body is fixedly connected to the inner side of the first side wall, a water-absorbing factor filler is filled between the protective body and the first side wall, the water-absorbing factor filler is used to absorb liquid to become a jelly-like state, the outer side of the protective body can be against the second side wall, and a guide groove is arranged on the inner side of the first side wall, one end of the guide groove is close to the end of the conduit, and the other end of the guide groove extends between the protective body and the first side wall.

[0007] By adopting the above technical scheme, when the waste liquid enters the bag body through the catheter, part of the waste liquid directly enters the inside of the bag body, while the other part of the waste liquid will flow along the guide groove to the inside of the protective body, and the two parts of the waste liquid are separated by the protective body. The water-absorbing factor filler in the protective body absorbs the waste liquid and converts it into a jelly-like state. The volume of the water-absorbing factor filler expands accordingly, thereby propping up the protective body. The outside of the protective body can lift up the center of the second side wall, thereby propping up the center of the inner side of the bag body and increasing the internal space of the bag body; wherein the protective body has a limiting and isolating effect on the water-absorbing factor filler, limits the expansion position of the water-absorbing factor filler, and isolates the water-absorbing factor filler from the waste liquid outside the protective body, ensuring that the water-absorbing factor filler is stably located in the center of the bag body, effectively improving the utilization rate of the bag body, reducing the waste of internal space, and also ensuring the stability of the bag body structure.

[0008] Preferably, a plurality of support bodies are fixedly disposed inside the protective body, and the support bodies are spaced apart from each other.

[0009] By adopting the above technical scheme, when waste liquid is not introduced, the support body can support the protective body. At this time, the gap between the support bodies acts as a channel, which is convenient for the dispersion and transmission of waste liquid. When the water-absorbing factor filler begins to expand, it preferentially expands toward the intervals between the protective bodies, so that the force on the inner side of the protective body is more uniform, preventing the protective body from excessive deformation, which is conducive to better exerting the role of the water-absorbing factor filler and further improving the utilization rate and use effect of the bag body.

[0010] Preferably, the support body is arranged in a long strip shape, the length direction of the support body is perpendicular to the central axis direction of the liquid inlet pipe, and a gap is left between the end of the support body and the edge of the protective body.

[0011] By adopting the above technical scheme, the long strip support body plays the role of a rib, avoiding local bulges of the protection body as much as possible, and further improving the uniformity of the force on the inner side of the protection body. The support body is arranged in a direction perpendicular to the central axis of the liquid inlet pipe, which helps to support the protection body more evenly, and a gap is left between the end of the support body and the edge of the protection body, which provides a certain space for the adjustment of waste liquid between the intervals of each support body, so that the water-absorbing factor filler can play a role more smoothly and fully during the expansion process. In summary, the use effect of the bag body and the utilization rate of space are further improved, and it is also beneficial to maintain the integrity and stability of the protection body structure.

[0012] Preferably, the support body is made of ABS material.

[0013] By adopting the above technical solution, the ABS material has good strength and toughness, can provide reliable and lasting support for the protector, ensure the stability of the protector structure during storage or use, and maintain good performance even when the filler expands due to water absorption factors, further improving the overall quality and durability of the portable waste liquid collection bag. At the same time, the cost of ABS material is relatively reasonable, which is conducive to controlling the cost of the product.

[0014] Preferably, several bag bodies are arranged on the connector, and all the bag bodies are arranged at intervals along the same straight line direction on the connector; the conduit includes a liquid inlet pipe, a liquid outlet pipe, and a connecting pipe, the liquid inlet pipe is fixedly arranged at one end of the connector, and the liquid outlet pipe is fixedly arranged at the other end of the connector, the bag body closest to the liquid inlet pipe is directly connected to the liquid inlet pipe, the bag body closest to the liquid outlet pipe is directly connected to the liquid outlet pipe, and adjacent bag bodies are connected to each other through connecting pipes.

[0015] By adopting the above technical solution, the liquid inlet pipe and the liquid outlet pipe are respectively located at both ends of the connecting body, which facilitates the entry and discharge of waste liquid. The connecting pipe connects adjacent bag bodies, ensuring the connectivity between the bag bodies and the continuity of waste liquid collection. The bag bodies are set to be several and arranged at intervals along the same straight line direction. The waste liquid can flow through each bag body in turn, realizing the orderly collection and transmission of the waste liquid. On the one hand, the collection capacity of the waste liquid is increased to meet the needs of different waste liquid volumes. On the other hand, the side wall area of ​​the bag body required to be supported by a single protective body is reduced, thereby reducing the support strength borne by a single protective body.

[0016] Preferably, both the liquid inlet pipe and the liquid outlet pipe are provided with a blocking clamp, and the blocking clamp is used to block the flow of liquid in the liquid inlet pipe or the liquid outlet pipe.

[0017] By adopting the above technical solution, when it is necessary to suspend waste liquid collection or perform other operations, the flow of liquid in the liquid inlet pipe or the liquid outlet pipe can be conveniently blocked by the blocking clamp, thereby increasing the flexibility and controllability of the waste liquid collection operation process and improving the convenience and safety of using the portable waste liquid collection bag.

[0018] Preferably, a hanging ring is provided on the connector, and the hanging ring is located at one end of the connector close to the liquid inlet pipe.

[0019] By adopting the above technical solution, the setting of the hanging ring makes it convenient to hang the entire portable waste liquid collection bag, which is convenient for placement and fixation during use. Especially when it needs to be fixed in a specific position for waste liquid collection, a convenient hanging point is provided, which increases the convenience and adaptability of use. The hanging ring is located at one end of the connector close to the liquid inlet pipe, which facilitates the waste liquid to flow downward from the liquid inlet pipe into the bag body during the hanging process, thereby facilitating the guidance of the waste liquid into the bag.

[0020] Preferably, the connector is also provided with a docking buckle, which includes a sub-buckle and a mother buckle. A connecting belt is fixedly provided at one end of the connector, the sub-buckle is fixed on the connecting belt, and the mother buckle is fixed at the other end of the connector, and the sub-mouth and the mother buckle can dock with each other.

[0021] By adopting the above technical solution, when the patient needs to move and walk, the sub-opening on the connecting belt at one end of the connector can be engaged with the female buckle at the other end of the connector to achieve a quick and stable connection. The connector can be bent to reduce its length and avoid the connector being dragged to the ground when the patient moves. The flexibility of the collection bag is enhanced to meet the diverse needs for waste liquid collection in different scenarios. At the same time, when collecting large quantities of waste liquid, it is convenient to connect the sub-buckles and female buckles of different storage bags, which facilitates the centralized storage and processing of the collection bags.

[0022] Preferably, the conduits are extended and extend into the interior of the bag body, and the conduits are fixedly connected to the first side wall inside the bag body.

[0023] By adopting the above technical solution, the catheter is extended and extends into the interior of the bag body and is fixedly connected to the first side wall, so that the waste liquid is more stable and smooth when entering and flowing out of the bag body, and one end of the guide groove is close to the end of the catheter. When the waste liquid enters and flows out of the bag body, it is easier to enter the interior of the protective body along the guide groove due to the capillary effect of the waste liquid, further improving the use effect and reliability of the portable waste liquid collection bag, and is also beneficial to the control and guidance of the waste liquid.

[0024] Preferably, the bag body is made of PVC material.

[0025] By adopting the above technical solution, PVC material has good flexibility, corrosion resistance and durability. Using it to make the bag body can ensure that the bag body is not easily damaged during use, can adapt to different use environments and conditions, and can better maintain its shape, which is conducive to the collection and storage of waste liquid. At the same time, the cost of PVC material is relatively low, which is also conducive to reducing the overall production cost of portable waste liquid collection bags.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up the protective body, water-absorbing factor filler and diversion groove, after the waste liquid enters the bag body, the water-absorbing factor filler absorbs the waste liquid and converts it into a jelly-like colloid to expand its volume, thereby supporting the center of the bag body, effectively improving the utilization rate of the bag body, reducing the waste of internal space, and also ensuring the stability of the bag body structure; 2. By setting the support body, it plays a supporting role for the protection body when the waste liquid is not introduced. When the water-absorbing factor filler expands, the force on the inside of the protection body is more uniform, which prevents the protection body from excessive deformation, is conducive to better play the role of the water-absorbing factor filler, and further improves the utilization rate and use effect of the bag body; 3. By setting up multiple bag bodies, the orderly collection and transmission of waste liquid can be achieved, the collection capacity is increased, the blocking clip is set to increase the operational flexibility, the hanging ring is convenient for hanging, and the docking buckle is convenient for use in special scenes and centralized storage, which improves the practicality of the portable waste liquid collection bag as a whole.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a portable waste liquid collection bag. Figure 1 , which comprises a connector 1, on which a bag body 2 made of PVC material is arranged. Each bag body 2 is provided with two conduits 21 connected thereto, one of which is used to introduce waste liquid into the bag body 2, and the other conduit 21 is responsible for leading the waste liquid out of the bag body 2.

[0033] Reference Figure 2, one side wall of the bag body 2 is the first side wall 22, and the other side wall of the bag body 2 is the second side wall 23. A protective body 24 is provided at the center of the inner side of the first side wall 22. The protective body 24 is a soft film structure, and the edge of the protective body 24 is fixedly connected to the inner side of the first side wall 22. A water-absorbing factor filler 27 is filled between the protective body 24 and the first side wall 22. The water-absorbing factor filler 27 is used to absorb liquid and become a jelly gelatinous state, which can be specifically a hydrogel. The outer side of the protective body 24 can be against the second side wall 23. All the conduits 21 are extended and extend into the interior of the bag body 2. The conduits 21 are fixedly connected to the first side wall 22 inside the bag body 2. A guide groove 25 is provided on the inner side of the first side wall 22, and one end of the guide groove 25 is close to the end of the conduit 21, and the other end extends into the protective body 24.

[0034] Reference Figure 1 and Figure 2 When the waste liquid enters the bag body 2 through the conduit 21, part of the waste liquid directly enters the bag body 2, while the other part of the waste liquid will flow along the guide groove 25 to the inside of the protective body 24 due to the capillary phenomenon of the liquid. The water-absorbing factor filler 27 in the protective body 24 absorbs the waste liquid and converts it into a jelly-like state, and its volume expands accordingly, thereby propping up the protective body 24, thereby propping up the center of the second side wall 23, thereby propping up the center of the inner side of the bag body 2, preventing the bag body 2 from deforming with the flow of waste liquid, increasing the internal space of the bag body 2, and improving the utilization rate of the bag body 2.

[0035] In order to make the protective body 24 more reliably support the bag body 2, refer to Figure 2 and Figure 3 A plurality of support bodies 241 made of ABS material are fixedly arranged inside the protection body 24, and the support bodies 241 are arranged in a long strip shape. The length direction of the support body 241 is perpendicular to the central axis direction of the liquid inlet pipe 211, and there is a gap between the end of the support body 241 and the edge of the protection body 24, and the support bodies 241 are spaced apart from each other. Before the water-absorbing factor filler 27 absorbs water or the degree of water absorption is insufficient, the support body 241 can support the protection body 24. After the water-absorbing factor filler 27 does not absorb water, the support body 241 plays the role of a rib, which helps to support the protection body 24 more evenly, so that the protection body 24 can more reliably support the center of the bag body 2.

[0036] In order to increase the waste collection capacity and reduce the frequency of waste treatment, refer to Figure 1, three bags 2 are arranged on the connector 1, and all bags 2 are arranged at intervals along the same straight line direction on the connector 1. The conduit 21 is specifically divided into a liquid inlet pipe 211, a liquid outlet pipe 212, and a connecting pipe 213. The liquid inlet pipe 211 is fixedly arranged at one end of the connector 1, and the liquid outlet pipe 212 is fixedly arranged at the other end of the connector 1. The bag 2 closest to the liquid inlet pipe 211 is directly connected to the liquid inlet pipe 211, and the bag 2 closest to the liquid outlet pipe 212 is directly connected to the liquid outlet pipe 212. Adjacent bags 2 are connected to each other through the connecting pipe 213. Blocking clips 26 are arranged on both the liquid inlet pipe 211 and the liquid outlet pipe 212, and the blocking clips 26 are used to block the flow of liquid in the liquid inlet pipe 211 or the liquid outlet pipe 212.

[0037] Reference Figure 1 When collecting waste liquid, the liquid inlet pipe 211 is connected to the catheter 21 on the patient, and the waste liquid can flow through each bag body 2 in sequence, increasing the collection capacity of the waste liquid and meeting the needs of different waste liquid volumes. When processing the waste liquid, the liquid outlet pipe 212 is connected to other waste liquid processing equipment or pipelines to achieve continuous processing and transfer of the waste liquid. At the same time, the blocking clamp 26 can be used to flexibly block the flow of liquid in the liquid inlet pipe 211 or the liquid outlet pipe 212, thereby improving the safety of the entire collection system and reducing the possibility of risks caused by accidental leakage of waste liquid.

[0038] In order to improve the convenience of waste liquid collection bags, refer to Figure 1 , a hanging ring 11 is provided on the connector 1, and the hanging ring 11 is located at one end of the connector 1 close to the liquid inlet pipe 211. A docking buckle is also provided on the connector 1, and the docking buckle includes a sub-buckle 121 and a mother buckle 13. A connecting belt 12 is fixedly provided at one end of the connector 1, and the sub-buckle 121 is fixedly provided on the connecting belt 12. The mother buckle 13 is fixedly provided at the other end of the connector 1, and the sub-mouth and the mother buckle 13 can be docked with each other. The hanging ring 11 can hang the entire portable waste liquid collection bag, which is convenient for the placement and fixation of the collection bag during use. When the patient needs to move and carry the collection bag, the connector 1 can be bent by docking the sub-buckle 121 and the mother buckle 13, thereby reducing its overall length and facilitating the patient to move and carry.

[0039] The implementation principle of a portable waste liquid collection bag in the embodiment of the present application is as follows: when collecting waste liquid, the entire collection bag is hung up by the hanging ring 11. The liquid inlet pipe 211 is connected to the catheter 21 on the patient, and a negative pressure source is generated by a portable negative pressure device to guide the waste liquid from the liquid inlet pipe 211 into the bag body 2, and is guided to each bag body 2 in sequence by the connecting pipe 213. After the waste liquid enters the bag body 2, part of the waste liquid directly enters the inside of the bag body 2, while the other part of the waste liquid will flow along the guide groove 25 to the inside of the protective body 24 due to the capillary phenomenon of the liquid. The water-absorbing factor filler 27 in the protective body 24 absorbs the waste liquid and converts it into a jelly-like colloid state, and the volume expands accordingly, thereby propping up the protective body 24, thereby lifting up the center of the second side wall 23, thereby propping up the center of the inner side of the bag body 2, preventing the bag body 2 from deforming with the flow of waste liquid, and increasing the internal space of the bag body 2, so as to improve the utilization rate of the bag body 2.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
