Description

Technical Field

[0001] This utility model relates to the field of blood perfusion device technology, specifically a blood perfusion device connecting tube that allows for waste liquid recycling. Background Technology

[0002] The hemoperfusion device connecting tubing is an indispensable component in the hemoperfusion treatment process. It is mainly used to connect the hemoperfusion device to other extracorporeal circulation equipment, such as hemodialysis machines.

[0003] Existing hemoperfusion device connectors are typically connected to the arterial end of the dialysis tubing. After the dialysis tubing is installed into the dialysis machine, saline solution is used to pre-flush the arterial end of the tubing under gravity. Once the dialysis machine has completed the pre-flush of the entire dialysis tubing, the two sets of dialysis tubing need to be connected via a connector. This method of connecting the tubing can easily cause saline solution to spill onto the ground, resulting in saline solution loss. It also makes the ground slippery, increasing the risk of pedestrians falling and increasing the risk of contamination at the tubing interfaces. Utility Model Content

[0004] The purpose of this invention is to provide a blood perfusion device connecting tube that can recycle waste liquid, so as to solve the problem mentioned in the background art that the existing blood perfusion device connecting tubes need to be connected by connecting tubes, which is prone to pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blood perfusion device connecting tube with recyclable waste liquid, comprising: an arterial end pipe a and a waste liquid collection bag, a venous end pipe b is provided on one side of the arterial end pipe a, pipe c is fixedly connected to the top of both the arterial end pipe a and the venous end pipe b, the top of each pipe c is connected to the bottom of the waste liquid collection bag, a switch clamp a is engaged on the outside of the pipe c, a pipe interface is fixedly connected to the middle of both the arterial end pipe a and the venous end pipe b, and a switch clamp c is engaged at the end of the arterial end pipe a near the pipe interface.

[0006] Preferably, the end of the arterial end conduit a away from the switch clamp c is engaged with a switch clamp b, and the end of the venous end conduit b near the conduit c is engaged with a switch clamp d.

[0007] Preferably, the end of the venous end conduit b away from the switch clamp d is engaged with the switch clamp e, and the arterial end conduit a, the venous end conduit b and the conduit c together form a "Y" shape.

[0008] Preferably, the bottom of the arterial end conduit a is fixedly connected to a connecting block a via a ring, and a connecting rod is fixedly connected to one side of the connecting block a.

[0009] Preferably, one end of the connecting rod is fixedly connected to two sets of protrusions, the protrusions are made of rubber, and one side of the connecting block a is fixedly connected to a limit clamp a.

[0010] Preferably, the bottom of the venous end conduit b is fixedly connected to a connecting block b by a ring, and the connecting block b has a through hole inside that matches the connecting rod.

[0011] Preferably, a limiting clamp b is fixedly connected to one side of the connecting block b, and a rubber sleeve is fixedly connected to one side of the arterial end conduit a.

[0012] Compared with existing technologies, the advantages of this waste fluid recyclable blood perfusion device connecting tube are:

[0013] 1. Under normal conditions, all four switch clamps (a, b, c, d, and e) of the hemoperfusion device connecting tubing are open. After the tubing is installed, the arterial end tubing (a) can be filled with saline solution. Then, switch clamp (c) is closed, and the venous end tubing (b) and dialyzer are pre-flushed. After pre-flushing, switch clamp (a) is closed and switch clamp (c) is opened to begin the cyclic pre-flushing process. Waste liquid generated during the operation can be collected through a waste liquid collection bag. This process facilitates a sealed pre-flushing operation of the hemoperfusion device connecting tubing.

[0014] 2. The hemoperfusion device connecting tube with waste liquid recovery is connected by aligning the connecting rod on one side of the connecting block a at the bottom of the arterial end tube a with the through hole in the connecting block b at the bottom of the venous end tube b. When the rubber protrusion enters the through hole, it will deform. When the protrusion passes through the through hole, it will return to its original position, thereby locking the connecting rod with the connecting block b, completing the connection between the arterial end tube a and the venous end tube b. Subsequently, the limiting clamps a and b on one side of the connecting blocks a and b can be inserted into the rubber sleeve on one side of the tube c to complete the storage of the arterial end tube a, the venous end tube b, and the waste liquid collection bag. In this way, the tube of the hemoperfusion device connecting tube can be easily stored. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a blood perfusion device connecting tube with recyclable waste liquid, including: an arterial end pipe a1 and a waste liquid collection bag 4. A venous end pipe b2 is provided on one side of the arterial end pipe a1. The top of both the arterial end pipe a1 and the venous end pipe b2 are fixedly connected to pipes c3. The top of each pipe c3 is connected to the bottom of the waste liquid collection bag 4. A switch clamp a5 is engaged on the outside of pipe c3. A pipe interface 8 is fixedly connected in the middle of both the arterial end pipe a1 and the venous end pipe b2. A switch clamp c7 is engaged at the end of the arterial end pipe a1 near the pipe interface 8.

[0022] The end of arterial conduit a1 away from switch clamp c7 is engaged with switch clamp b6, and the end of venous conduit b2 near conduit c3 is engaged with switch clamp d9; the end of venous conduit b2 away from switch clamp d9 is engaged with switch clamp e10. Arterial conduit a1, venous conduit b2 and conduit c3 together form a "Y" shape.

[0023] In practice, under normal conditions, all four switch clamps (a5, b6, c7, d9, and e10) of the recyclable hemoperfusion device connecting tubing are in the open position. After the tubing is installed, the arterial end tubing (a1) can be filled with saline solution. Then, switch clamp (c7) is closed, and the venous end tubing (b2) and dialyzer are pre-flushed. After pre-flushing, switch clamp (a5) is closed and switch clamp (c7) is opened to begin the circulation pre-flushing process. The above operation is suitable for the following situations: when there is no heparin circulation tubing, the heparin-free tubing does not circulate but requires thorough humidification. When the blood perfusion device is in the pre-flushing device, after connecting the tubing and simulating the starting point, since the arterial end tubing a1, the venous end tubing b2, and the tubing c3 are in a closed state, no other tubing connection is required. Therefore, aseptic operation can be performed. The heparin-free circulation is completed by switching multiple sets of switch clamps, simultaneously simulating the starting point and the pre-flushing process. Furthermore, no tubing is exposed during the operation, which reduces the risk of contamination and saves saline. Waste liquid during the operation can be collected through waste liquid collection bag 4. Thus, the above operation facilitates a sealed pre-flushing operation on the blood perfusion device connecting tubing.

[0024] The bottom of the arterial end conduit a1 is fixedly connected to a connecting block a11 via a ring, and a connecting rod 12 is fixedly connected to one side of the connecting block a11; one end of the connecting rod 12 is fixedly connected to two sets of protrusions 13, which are made of rubber, and a limiting clamp a14 is fixedly connected to one side of the connecting block a11; the bottom of the venous end conduit b2 is fixedly connected to a connecting block b15 via a ring, and a through hole 16 matching the connecting rod 12 is opened inside the connecting block b15; a limiting clamp b18 is fixedly connected to one side of the connecting block b15, and a rubber sleeve 17 is fixedly connected to one side of the arterial end conduit a1.

[0025] In specific implementation, when storing the arterial end tube a1, venous end tube b2, and tube c3 of the recyclable hemoperfusion device, the connecting rod 12 on one side of the bottom connecting block a11 of the arterial end tube a1 is aligned with the through hole 16 in the bottom connecting block b15 of the venous end tube b2. When the rubber protrusion 13 enters the through hole 16, it will deform. When the protrusion 13 passes through the through hole 16, it will return to its original position, thereby engaging the connecting rod 12 with the connecting block b15 and completing the connection between the arterial end tube a1 and the venous end tube b2. Subsequently, the limiting clamps a14 and b18 on one side of the connecting block a11 and the connecting block b15 can be inserted into the rubber sleeve 17 on the side of the tube c3 to limit the arterial end tube a1, the venous end tube b2, and the waste collection bag 4, preventing the hemoperfusion device connecting tube from becoming scattered. In this way, the hemoperfusion device connecting tube can be easily stored.

[0026] In summary: When using a hemoperfusion device connecting tube with recyclable waste liquid, first install the arterial end tubing a1 and the venous end tubing b2 of the hemoperfusion device connecting tube onto the dialysis machine, and then pre-flush the hemoperfusion device connecting tube. The contents not described in detail in this instruction are prior art known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
