[0002] Peritoneal dialysis is a treatment method that replaces kidney function. It uses the surface of the peritoneal cavity membrane to perform dialysis to expel waste and excess water from the human body. This method injects dialysate into the abdominal cavity to exchange the dialysate with the blood in the peritoneal cavity, thereby achieving the purpose of removing toxins and excess water from the blood.

[0003] Currently, there is no special switch on the infusion tube of the double-linked double bag peritoneal dialysis fluid device for containing peritoneal dialysis fluid. Therefore, when patients undergo peritoneal dialysis, they need to be equipped with a clamp to clamp the infusion tube in the device. When the clamp is clamped on the infusion tube, the liquid in the infusion tube will stop flowing directly, and the flow rate of the liquid in the infusion tube cannot be controlled according to demand. At the same time, the clamp is easily damaged during use, and if the clamping position of the clamp is incorrect, the liquid in the infusion tube will leak. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] The embodiment of the utility model provides a peritoneal dialysis infusion regulator, comprising an infusion bag 1 and an infusion tube 2 connected to a liquid outlet, the infusion tube 2 is sleeved with a sleeve 3 on the outside, a clamping piece 4 is fixedly arranged on both sides of the top of the sleeve 3, and the bottoms of the two clamping pieces 4 are fixedly connected to the top of the sleeve 3, and the two clamping pieces 4 are close to each other on one side to form a space for the infusion tube 2 to pass through, and the sleeve 3 is provided with a flow rate regulating member 5 that can squeeze the two clamping pieces 4;

[0025] When it is necessary to adjust the flow rate of the dialysate in the infusion tube 2, the medical staff can manually operate the flow rate adjusting member 5 on the sleeve 3, and the distance between the two clamping pieces 4 set on the sleeve 3 can be adjusted by the flow rate adjusting member 5. When the medical staff manipulates the flow rate adjusting member 5 to gradually move upward on the sleeve 3, the two clamping pieces 4 will be gradually squeezed, so that the front ends of the two clamping pieces 4 will gradually squeeze the infusion tube 2, so that the flow channel in the infusion tube 2 gradually becomes smaller, thereby gradually reducing the flow rate of the dialysate in the infusion tube 2. When the two clamping pieces 4 are squeezed to the specified position, the position where the infusion tube 2 is clamped is When the flow rate adjusting member 5 is set, the flow channel inside it will be completely closed, so that the dialysate in the infusion tube 2 will stop flowing. When the medical staff manipulates the flow rate adjusting member 5 to gradually move downward on the sleeve 3, the two clamping pieces 4 will gradually release the squeezing of the infusion tube 2 due to their own elasticity, so that the flow channel in the infusion tube 2 will slowly open to allow the dialysate to flow. Through the cooperation of the sleeve 3, the clamping pieces 4 and the flow rate adjusting member 5, the effect of controlling the opening and closing of the flow channel in the infusion tube 2 is achieved. At the same time, the size of the flow channel in the infusion tube 2 can be adjusted according to needs, thereby adjusting the flow rate of the dialysate.

[0026] In a further embodiment, the flow rate regulating member 5 includes a rotating tube 51 and a holding portion 52, wherein the rotating tube 51 is movably arranged outside the sleeve 3, and the holding portion 52 is sleeved outside the sleeve 3 and located below the rotating tube 51, and the inner wall of the holding portion 52 is fixedly connected to the outer wall of the sleeve 3;

[0027] When using the flow rate adjusting member 5, the medical staff can hold the holding portion 52 on the sleeve 3 with one hand, and then use the other hand to operate the rotating tube 51 to rotate upward on the sleeve 3, thereby squeezing the two clamping pieces 4 at the upper end of the sleeve 3 from bottom to top, thereby changing the distance between the clamping ends of the two clamping pieces 4, thereby adjusting the size of the flow channel in the infusion tube 2.

[0028] In a further embodiment, the outer wall of the upper half of the sleeve 3 is provided with an external thread 31, and the interior of the rotating tube 51 is provided with an internal thread 53 that cooperates with the external thread 31 provided on the outer wall of the sleeve 3;

[0029] When the medical staff rotates the rotating tube 51 on the sleeve 3, the internal thread 53 set in the rotating tube 51 and the external thread 31 set on the outer wall of the sleeve 3 cooperate to enable the rotating tube 51 to move up and down on the sleeve 3, and when the rotating tube 51 does not need to be rotated anymore, the rotating tube 51 will not move randomly on the sleeve 3 due to the cooperation between the internal thread 53 and the external thread 31.

[0030] In a further embodiment, the outer cross section of the rotating tube 51 is triangular, and each outer corner is rounded;

[0031] When medical personnel use the device, by setting the rotating tube 51 with a triangular outer shape, when the medical personnel holds other things in one hand and only the other hand can be used, the medical personnel uses the free hand to hold the grip 52, and then uses the thumb, index finger and middle finger of the hand to respectively press against the three surfaces of the rotating tube 51 with a triangular shape, and then uses the thumb, index finger and middle finger to simultaneously exert force to move the rotating tube 51, so that the rotating tube 51 can be moved up and down on the sleeve 3, thereby squeezing or releasing the squeezing of the two clamping pieces 4 on the sleeve 3. Therefore, the device can also be operated with one hand, which can avoid the problem that the medical personnel cannot adjust the device when both hands cannot be used at the same time.

[0032] In a further embodiment, a stopper 41 is fixedly provided on the outer wall of the upper ends of the two clamping pieces 4, and a ring-shaped gasket 54 is fixedly provided on the outer wall of one end of the holding portion 52 close to the rotating tube 51;

[0033] By setting the stopper 41, after the rotating tube 51 moves upward to the specified position, the top of the rotating tube 51 will abut against the stopper 41 set on the two clamping pieces 4. At this time, it means that the rotating tube 51 has moved up to the limit position, thereby prompting the medical staff that they can no longer control the rotating tube 51 to move upward. At the same time, when the top of the rotating tube 51 abuts against the stopper 41 on the two clamping pieces 4, the clamping of the two clamping pieces 4 on the infusion tube 2 also reaches the limit, which means that the dialysate in the infusion tube 2 will stop flowing. When the medical staff controls the rotating tube 51 to move downward to the specified position, the bottom of the rotating tube 51 will abut against the gasket 54 at the top of the holding portion 52, so that the rotating tube 51 can no longer move downward, thereby preventing the rotating tube 51 from directly detaching from the sleeve 3.

[0034] In a further embodiment, a clamping strip 42 is fixedly provided on the upper end of one side of the two clamping pieces 4 abutting against the infusion tube 2, and the length of the clamping strip 42 is greater than the diameter of the infusion tube 2, and the two clamping strips 42 are both horizontally placed on the two corresponding clamping pieces 4;

[0035] When the two clamping pieces 4 are squeezed close to each other, the clamping strips 42 on the upper ends of the two clamping pieces 4 will squeeze the clamping parts of the infusion tube 2. When the two clamping pieces 4 are squeezed to the limit, the two clamping strips 42 will tightly fit the inner walls of the clamping parts of the infusion tube 2 together, thereby ensuring that the flow channel in the infusion tube 2 will not leak.

[0036] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
