Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of peritoneal dialysis, and particularly relates to a peritoneal dialysate double connection system. BACKGROUND

[0002] Peritoneal dialysis is to use the peritoneum as a semi-permeable membrane, and to pour prepared dialysate into the peritoneal cavity of a patient through a catheter by gravity, so that metabolic products, toxic substances in the body can be removed, and water and electrolyte balance disorders can be corrected by constantly replacing the dialysate in the abdominal cavity.

[0003] In the current peritoneal dialysis system, the inflow pipe and the outflow pipe of the peritoneal dialysate double connection system are both straight pipes connected from a dialysate bag and a waste liquid bag to form a Y-shaped pipe, and medical staff cannot intuitively monitor the flow of the dialysate and the waste liquid, which will lead to the failure to timely discover and handle abnormal conditions, such as poor liquid flow, liquid flow rate, and whether the waste liquid is completely discharged. CONTENT OF THE INVENTION

[0004] In order to improve the problem that the flow of the dialysate and the waste liquid cannot be intuitively monitored in the current peritoneal dialysate double connection system, the present application provides a peritoneal dialysate double connection system.

[0006] The peritoneal dialysate double connection system comprises a dialysate bag and a waste liquid bag, the dialysate bag is connected with an inflow pipe, the waste liquid bag is connected with an outflow pipe, a Y-shaped pipe is connected between the free ends of the inflow pipe and the outflow pipe, and a Murphy's dropping tube is fixedly connected on the inflow pipe and the outflow pipe.

[0007] Furthermore, a reverse flow preventer is fixedly connected on the connection between the outflow pipe and the waste liquid bag, and the reverse flow preventer only allows liquid to flow from the outflow pipe to the waste liquid bag.

[0008] Furthermore, the reverse flow preventer comprises:

[0009] a pipe sleeve connected between the outflow pipe and the waste liquid bag;

[0012] Furthermore, the plurality of reverse flow flaps are integrally enclosed in a conical shape.

[0013] Furthermore, a medicine adding pipe is fixedly connected on the bottom of the outer wall of the dialysate bag, and a pipe cap one is connected on the pipe opening of the medicine adding pipe.

[0016] Further, the outer wall of the liquid outlet pipe and / or the liquid inlet pipe is sleeved with a medical catheter clamp.

[0017] Further, the medical catheter clamp is located between the Mohr dropper and the Y-shaped pipe.

[0018] Further, the outer wall of the dialysis liquid bag is fixedly connected with a hook at the top.

DETAILED DESCRIPTION

[0030] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] With reference to Figure 1 , the present application discloses a peritoneal dialysis liquid double connection system, which comprises a dialysate bag 1 and a waste liquid bag 2. The dialysate bag 1 is provided with a hook fixedly connected to the top of the outer wall, so as to facilitate hooking the dialysate bag 1 on a liquid infusion support. The dialysate bag 1 is provided with a liquid outlet fixedly communicated with a liquid inlet tube 4, and the waste liquid bag 2 is provided with a liquid inlet fixedly communicated with a liquid outlet tube 5. The liquid inlet tube 4 and the liquid outlet tube 5 are provided with a Y-shaped tube 3 therebetween. The upper ends of the Y-shaped tube 3 are fixedly communicated with the liquid inlet tube 4 and the liquid outlet tube 5, respectively. The liquid inlet tube 4 and the liquid outlet tube 5 are both provided with a Mohr's dropper 6 fixedly communicated therewith.

[0032] Thus, by arranging the Mohr's dropper 6 on the liquid inlet tube 4 and the liquid outlet tube 5, medical staff can intuitively monitor the flow of dialysate and waste liquid, and timely discover and handle abnormal conditions such as poor liquid flow, liquid flow rate, and whether the waste liquid is completely discharged, so as to ensure the smooth progress of dialysis.

[0033] Further, considering that in the dialysis process, a patient with poor cooperation may cause the pressure of the waste liquid bag 2 to change with the patient's activity and body position change, which may cause the waste liquid in the waste liquid bag 2 to flow back to the dialysis pipeline, or even back to the patient's abdomen. This not only affects the dialysis effect, but also causes the risk of peritonitis to the patient.

[0034] Therefore, with reference to Figure 2 and Figure 3A reverse flow preventer 7 is fixedly connected at the connection between the liquid outlet pipe 5 and the waste liquid bag 2, and the reverse flow preventer 7 only allows liquid to flow from the liquid outlet pipe 5 to the waste liquid bag 2. The reverse flow preventer 7 comprises a pipe sleeve 15 connected between the liquid outlet pipe 5 and the waste liquid bag 2, and a fixing ring 13 is fixedly connected to the inner wall of the pipe sleeve 15 away from the waste liquid bag 2. A plurality of reverse flow petals 14 are fixedly connected to the surface of the fixing ring 13, and the plurality of reverse flow petals 14 are distributed in an equidistant circumferential array along the central axis of the fixing ring 13. The plurality of reverse flow petals 14 extend towards the waste liquid bag 2, and the plurality of reverse flow petals 14 as a whole have a conical shape.

[0035] Therefore, by limiting the flow direction of the waste liquid in the liquid outlet pipe 5 through the reverse flow preventer 7, the waste liquid in the liquid outlet pipe 5 can only flow from the liquid outlet pipe 5 to the waste liquid bag 2, and the phenomenon of backflow of the waste liquid in the waste liquid bag 2 can be effectively avoided, thereby ensuring the dialysis effect.

[0036] In addition, when a patient needs to be subjected to a peritoneal dialysis balance test in the clinic, medical staff need to extract a sample from the waste liquid bag 2 for laboratory examination. There is no sampling structure when sampling, and the medical staff can only directly take the peritoneal dialysis liquid from the pipe opening of the waste liquid bag 2. This operation is not only inconvenient but also increases the risk of needle stick injury, and there is also a risk of contamination of the peritoneal dialysis liquid sample, which may lead to incorrect test results.

[0037] Therefore, with reference to the above Figure 1 A medicine adding pipe 9 is fixedly connected to the outer wall of the dialysis liquid bag 1, and a pipe cap one 10 is threadedly connected to the pipe opening of the medicine adding pipe 9. A sampling pipe 11 is fixedly connected to the outer wall of the waste liquid bag 2, and a pipe cap two 12 is threadedly connected to the pipe opening of the sampling pipe 11. Specifically, the pipe cap one 10 and the pipe cap two 12 can be cap bodies with medical rubber plugs, and medicine adding or sampling can be directly performed without leakage.

[0038] Therefore, the medical staff only need to pierce the pipe cap two 12 on the sampling pipe 11 with a sampling needle to directly sample the waste liquid in the waste liquid bag 2, without causing contamination and interfering with the normal dialysis.

[0039] Further, with reference to the above Figure 1 Medical catheter clamps 8 are sleeved on the outer walls of the liquid inlet pipe 4 and the liquid outlet pipe 5, and the two medical catheter clamps 8 are respectively located at one end of the two Mohr's droppers 6 close to the Y-shaped pipe 3. Therefore, the flow speed of the liquid in the liquid inlet pipe 4 and the liquid outlet pipe 5 can be controlled or even stopped by the medical catheter clamps 8, which greatly facilitates the operation of the medical staff.

[0040] The implementation principle of the peritoneal dialysis liquid double connection system according to the embodiment of the present application is as follows:

[0041] The peritoneal dialysis fluid double connection system of the present application is used in the following way: firstly, the medical staff ensures that the dialysis fluid bag 1 contains sufficient peritoneal dialysis fluid, and the waste fluid bag 2 is empty or ready to receive waste fluid. At this time, the pipe cap 1 10 on the medicine adding pipe 9 and the pipe cap 2 12 on the sampling pipe 11 are both in a tightly closed state to prevent external contamination.

[0042] When starting dialysis, the medical staff opens the medical catheter clamp 8 on the inflow pipe 4 to allow peritoneal dialysis fluid to flow from the dialysis fluid bag 1 through the inflow pipe 4 into the Y-shaped pipe 3. When the peritoneal dialysis fluid flows through the Mohr's dropping tube 6, the medical staff can directly observe the flow rate of the fluid and whether there are any abnormalities.

[0043] The peritoneal dialysis fluid continues to flow through the Y-shaped pipe 3 into the outflow pipe 5 and again passes through the Mohr's dropping tube 6 on the outflow pipe 5 for observation. The peritoneal dialysis fluid finally flows into the waste fluid bag 2, completing a dialysis cycle.

[0044] During the dialysis process, the pressure in the waste fluid bag 2 can change, but the anti-backflow device 7 can effectively prevent the waste fluid from flowing back to the outflow pipe 5 due to pressure changes, ensuring the unidirectional flow of the system.

[0045] When it is necessary to add medicine to the dialysis fluid, the medical staff can unscrew the pipe cap 1 10, inject medicine into the dialysis fluid bag 1 through the medicine adding pipe 9, and then re-tighten the pipe cap 1 10.

[0046] In order to monitor the dialysis effect or the composition of the waste fluid, the medical staff can unscrew the pipe cap 2 12, extract a small amount of waste fluid from the waste fluid bag 2 through the sampling pipe 11 for analysis, and then re-tighten the pipe cap 2 12.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacements to some of the technical features. Such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
