Background
Peritoneal dialysis is an alternative to hemodialysis, which uses a dialysate to dialyze through the abundant capillaries in the patient's peritoneal cavity, removing excess water and metabolic waste from the blood, and exchanging some of the nutrients into the blood. Compared with hemodialysis, peritoneal dialysis is more simple and easy to implement, and the cost of required equipment is lower.
A commonly used device for peritoneal dialysis is a peritoneal dialysis tube, which is inserted into the abdominal cavity and then the dialysate is infused or aspirated out of the abdominal cavity. Among the prior art, peritoneal dialysis pipe needs to sew up to patient's skin through the mounting that sets up the hole, and this kind of fixed mode can increase patient's misery, is unfavorable for the postoperative to be resumeed. Peritoneal dialysis pipe often does not possess velocity of flow control function, and the dislysate flows out very fast and can lead to patient's intra-abdominal cavity to form the negative pressure, leads to nethike embrane or other organs to be adsorbed on the dialysis hole and causes the jam of dialysis hole.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
In a specific embodiment of the present invention, an anti-drop peritoneal dialysis catheter, as shown in fig. 1 and 2, comprises: the inflatable air bag comprises a main pipe 1, an inflatable interlayer 2, an air bag 3, a connecting valve 4 and an inflatable joint 9; the main body tube 1 comprises a dialysis end 5 and a connecting end 6, wherein the dialysis end 5 is provided with a plurality of dialysis holes 7; the main body pipe 1 is arranged in the inflatable interlayer 2, the connecting end 6 is communicated with the connecting valve 4, and the inflatable interlayer 2 is communicated with the inflatable joint 9; the air bag 3 is fixed to the outside of the connecting end 6 and is communicated with the inflation connector 9.
In this embodiment, the device as a whole may use medical grade rubber as a material for placement in the abdominal cavity of a patient for dialysis. The inflatable interlayer 2 is attached to the outer wall of the main pipe 1, and the inflatable joint 9, the inflatable interlayer 2 and the air bag 3 are communicated. When the inflatable interlayer 2 is not inflated, the dialysis tube and the air bag 3 have smaller volumes and are easy to extend into the body of a patient. After the dialysis tube is inserted into the body of the patient, the inflatable interlayer 2 and the air bag 3 are inflated through the inflation connector 9, so that the inflatable interlayer 2 and the air bag 3 are expanded. In the main tube 1 is a fluid path for infusion and exchange of dialysate. The type of connection valve 4 can be chosen according to the type of external dialysate infusion and collection device. The air bag 3 is positioned on the inner side of the abdominal cavity of the patient, and the inner side of the abdominal cavity of the patient is clamped after expansion, so that the dialysis tube is prevented from being pulled out from the abdominal cavity of the patient. The air bag 3 can be set to be oval, and force can be uniformly dispersed on the inner side of the skin of a patient, so that the comfort of the patient is improved. The air bag 3 has simple structure, basically no harm to human body, safety and reliability. The device has simple integral structure and low cost, and is beneficial to batch production.
In a preferred embodiment, as shown in fig. 1 and 2, the dialysis tip 5 is provided with a curvature. Dialysis end 5 crooked setting, the dialysis hole 7 that is located dialysis end 5 inboard is difficult to be sheltered from by the nethike embrane, and the reliability is higher.
In a preferred embodiment, the anti-drop peritoneal dialysis catheter, as shown in fig. 1, further comprises a weight 10, wherein the weight 10 is fixed to the dialysis end 5. The counterweight 10 can be fixed to the dialysis end 5 by using a structure of internally-arranged metal and externally-wrapped medical rubber, so that the dialysis end 5 sinks into the dialysate to be beneficial to the outflow of the dialysate.
