Description

Technical Field

[0001] The utility model relates to a peritoneal dialysis tube, in particular to a peritoneal dialysis tube. Background Art

[0002] The peritoneal dialysis tube uses the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through the catheter by gravity. Due to the concentration gradient difference of the solutes on both sides of the peritoneum, the solutes on the high-concentration side move to the low-concentration side (diffusion effect); and the water moves from the hypotonic side to the hypertonic side (osmotic effect). The peritoneal dialysis fluid is continuously replaced to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance.

[0003] For example, the authorization announcement number is CN211068329U, which is a peritoneal dialysis tube. The above document can prevent the greater omentum fiber cords and other tissues in the abdominal cavity from completely wrapping around the dialysis tube from the outside and causing blockage of the dialysis holes by setting a protrusion. However, during the use of the peritoneal dialysis tube in the above document, the volume of the waste fluid in the patient's abdominal cavity accommodated by the drainage bag at the bottom is relatively single, so that the recovery volume of the drainage bag at the bottom of the peritoneal dialysis tube in the above document cannot be adjusted, resulting in that when a large amount of waste fluid is discharged from the patient's abdominal cavity, the drainage bag cannot be further recovered after it is full, and the peritoneal dialysis tube needs to be replaced, which easily causes the waste fluid in the user's abdominal cavity to flow out during the replacement process, making the peritoneal dialysis tube inconvenient to use. Summary of the invention

[0004] The utility model aims to solve the problem that the above-mentioned prior art cannot adjust the recovery volume of the drainage bag, and provides a peritoneal dialysis tube to achieve the specific function and effect of a peritoneal dialysis tube.

[0005] The utility model solves the technical problem by adopting a technical solution: the peritoneal dialysis tube

[0006] For further improvement, a peritoneal dialysis tube includes an intra-abdominal tube, the right end of the intra-abdominal tube is fixedly connected to a first connecting tube, the right side of the first connecting tube is connected to a second connecting tube, the right top of the second connecting tube is fixedly connected to a drug feed bag, a limiting component is provided at the bottom of the right end of the second connecting tube, the bottom end of the limiting component is fixedly connected to a drainage bag, the right top of the drainage bag is fixedly connected to a sampling port, and an auxiliary structure is provided at the bottom of the drainage bag.

[0007] To be further improved, the auxiliary structure includes a fixed rod, the end of the fixed rod is fixedly connected to the drainage bag, the two sides of the fixed rod are respectively threadedly connected to the screws on both sides, the inner end of the screw is rotatably connected to the guide block, the outer walls of the guide blocks on both sides are slidably connected to the fixed rod, the top of the guide block is fixedly connected to the wedge block, the top of the wedge block is tightly pressed against the limit rod, the two sides of the limit rod are respectively connected to the left ends of the support rods on both sides through pins, and the bottom ends of multiple support rods are fixedly connected to the fixed rod.

[0008] Further improvement, the bottom ends of the limit rods on both sides are tightly pressed against the drainage bag.

[0009] Further improvement, the outer wall of the fixing rod is intertwined with the drainage bag.

[0010] For further improvement, the top end of the medicine feeding bag is fixedly connected to the injection port.

[0011] Further improvement, the left end of the intra-abdominal tube is fixedly connected to the dialysis head.

[0012] The beneficial effect of the utility model is as follows: the utility model drives the guide block to move along the threaded groove of the fixed rod while rotating the screw rods on both sides, and at the same time, the guide block is restricted by the sliding groove of the fixed rod so that the screw rod rotates along the guide block, and the guide block drives the wedge block to move. During the outward movement of the wedge block, the wedge block and the limit rod are released from the tight contact, so that the limit rod can rotate outward along the support rod, so that the limit rod and the bottom of the drainage bag are released from the tight contact, so that the drainage bag is unfolded, thereby increasing the volume of waste liquid recovered by the drainage bag, and then realizing the adjustment of the recovery volume of the drainage bag, avoiding the situation that the original drainage bag cannot continue to recover after it is full and the peritoneal dialysis tube needs to be replaced, and the waste liquid is prone to outflow during the replacement process.

DETAILED DESCRIPTION

[0019] Embodiment 1: refer to the attached Figure 1-4 In the present embodiment, a peritoneal dialysis tube comprises an intra-abdominal tube 1, the right end of the intra-abdominal tube 1 is fixedly connected to a first connecting tube 3, the right side of the first connecting tube 3 is connected to a second connecting tube 5, the right top of the second connecting tube 5 is fixedly connected to a drug feed bag 6, a limiting component 8 is arranged at the right bottom of the second connecting tube 5, the limiting component 8 is a prior art, and the specific authorization announcement number is CN211068329U, the bottom end of the limiting component 8 is fixedly connected to a drainage bag 9, the right top of the drainage bag 9 is fixedly connected to a sampling port 10, and an auxiliary structure 4 is arranged at the bottom of the drainage bag 9.

[0020] The auxiliary structure 4 includes a fixed rod 4a1, the ends of which are fixedly connected to the drainage bag 9. The user rotates the screw rods 4a2 on both sides, and the screw rods 4a2 press the threaded grooves on both sides of the fixed rod 4a1 to rotate while driving the guide block 4a3 to move along the threaded groove of the fixed rod 4a1. At the same time, the guide block 4a3 is restricted by the sliding groove of the fixed rod 4a1 so that the screw rod 4a2 rotates along the guide block 4a3, and the guide block 4a3 drives the wedge block 4a4 to move. During the outward movement of the wedge block 4a4, the wedge block 4a4 and the limit rod 4a5 are released from the tight contact, so that the limit rod 4a5 can rotate outward along the support rod 4a6, so that the limit rod 4a5 and the bottom of the drainage bag 9 are released from the tight contact, thereby the drainage bag 9 is unfolded, thereby increasing the drainage bag 9. The volume of waste liquid is recovered, the two sides of the fixed rod 4a1 are respectively threadedly connected with the screw rods 4a2 on both sides, the inner end of the screw rod 4a2 is rotatably connected with the guide block 4a3, the outer walls of the guide blocks 4a3 on both sides are slidably connected with the fixed rod 4a1, the top of the guide block 4a3 is fixedly connected with the wedge block 4a4, the top of the wedge block 4a4 is tightly pressed against the limiting rod 4a5, the two sides of the limiting rod 4a5 are respectively connected with the left ends of the support rods 4a6 on both sides through pins, the bottom ends of multiple support rods 4a6 are fixedly connected with the fixed rod 4a1, the bottom ends of the limiting rods 4a5 on both sides are tightly pressed against the drainage bag 9, the outer wall of the fixed rod 4a1 is entangled with the drainage bag 9, the top of the medicine feed bag 6 is fixedly connected with the injection port 7, and the left end of the intra-abdominal tube 1 is fixedly connected with the dialysis head 2.

[0021] Working principle: the intra-abdominal tube 1 and the first connecting tube 3 are left in the patient's abdominal cavity. When dialysis is required, the first connecting tube 3 and the second connecting tube 5 are connected and fixed together. The dialysate in the liquid inlet bag 6 enters the intra-abdominal tube 1 through the liquid inlet tube and the second connecting tube 5, and then enters the patient's abdominal cavity through the dialyzer head 2, so as to perform dialysis. After a certain period of dialysis, the limit assembly 8 is rotated so that the waste liquid in the abdominal cavity enters the drainage bag 9 through the first connecting tube 3 and the second tube 5;

[0022] When the waste liquid inside the drainage bag 9 is filled, the user rotates the screw rods 4a2 on both sides. The screw rods 4a2 press the threaded grooves on both sides of the fixing rod 4a1 to rotate while driving the guide blocks 4a3 to move along the threaded grooves of the fixing rod 4a1. At the same time, the guide blocks 4a3 are restricted by the sliding grooves of the fixing rod 4a1, so that the screw rods 4a2 rotate along the guide blocks 4a3, and the guide blocks 4a3 drive the wedge blocks 4a4 to move. During the outward movement of the wedge blocks 4a4, the wedge blocks 4a4 and the limiting rods 4a5 are released from the tight contact, so that the limiting rods 4a5 can rotate outward along the supporting rods 4a6, so that the limiting rods 4a5 and the bottom of the drainage bag 9 are released from the tight contact, thereby unfolding the drainage bag 9, thereby increasing the volume of waste liquid recovered by the drainage bag 9, and then realizing the adjustment of the recovery volume of the drainage bag 9, avoiding the situation that the original drainage bag cannot continue to recover after it is full and needs to replace the peritoneal dialysis tube, which is prone to waste liquid outflow during the replacement process.

[0023] Example 2: Refer to the attached Figure 1-4 In the present embodiment, a peritoneal dialysis tube is provided, wherein the auxiliary structure 4 may further include a torsion spring 4b1, wherein the two ends of the torsion spring 4b1 are fixedly connected to the limit rod 4a5 and the support rod 4a6 respectively, and the elastic coefficient of the torsion spring 4b1 may be limited according to actual usage conditions. When the limit rod 4a5 is pressed against the drainage bag 9, the torsion spring 4b1 is in a deformed state, and when the limit rod 4a5 is released from the wedge block 4a4, the elastic force of the torsion spring 4b1 drives the limit rods 4a5 on both sides to rotate, so that the user can unfold the drainage bag more easily.

[0024] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
