Abstract
The utility model discloses an anti -return peritoneal dialysis pipe, including dislysate ascending pipe, dialysis waste liquid discharge pipe and back -flow preventer, back -flow preventer concatenates with dialysis waste liquid discharge pipe, and both ends all keep unobstructed, be provided with rotatable shell fragment in the back -flow preventer, the periphery of shell fragment and the laminating of back -flow preventer's inner wall, the shell fragment include stiff end and expansion end, length between stiff end and the expansion end is greater than back -flow preventer inner wall diameter, stiff end and back -flow preventer in the wall connection, the expansion end can rotate around the stiff end. The utility model discloses thereby avoided peritoneal dialysis patient to lead to infecting in the backward flow of treatment in -process dialysis waste liquid, had simple structure, with low costs, advantage that the facilitate promotion was used.
Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of anti-return peritoneal dialysis catheter.
Background technology
Renal failure and poor kidney can be treated by dialysis, and dialysis is discharged from human body at refuse, toxin and unnecessary water in body.Two kinds of essential therapeutic arsenals of hemodialysis and the current middle end stage renal patient of peritoneal dialysis.Because the patient of Blood Dialyzing Center at different levels is gradually saturated, and the cost of hemodialysis is higher, and peritoneal dialysis can retain the renal function of patient remnants to greatest extent, and treatment cost is lower, therefore peritoneal dialysis just adopt by increasing patient.
But, Patients With Kidney Diseases when carrying out peritoneal dialysis because many factors likely causes bacteriological infection, severe patient and then cause peritonitis, thus cause patient cannot continue to adopt peritoneal dialysis mode to treat, cause very large injury to patient, increase the financial burden of patient.And cause the factor of bacteriological infection one of them be dialyse waste liquid be expelled to external from abdominal cavity of patients time, antibacterial along with dialysis waste liquid backflow enter human abdominal cavity; This phenomenon more easily occurs in automated peritoneal dialysis.
Utility model content
The purpose of this utility model is to provide a kind of anti-return peritoneal dialysis catheter preventing dialysis waste reflux from entering human abdominal cavity.
The technical scheme realizing this utility model object is: a kind of anti-return peritoneal dialysis catheter, comprises dialysis solution ascending pipe, dialysis waste liquid discharge pipe and back-flow preventer;
Described back-flow preventer is connected in series with dialysis waste liquid discharge pipe, and two ends all keep clear; Rotating shell fragment is provided with in back-flow preventer, the periphery of shell fragment and the inwall of back-flow preventer are fitted, described shell fragment comprises stiff end and movable end, length between stiff end and movable end is greater than back-flow preventer inner diameter, described stiff end is connected with back-flow preventer inwall, and movable end can rotate around stiff end.
Compared with prior art, its remarkable result is this utility model:
This utility model is connected in series back-flow preventer in dialysis waste liquid discharge pipe, by arranging rotating shell fragment to prevent dialysis waste reflux, avoid patients undergoing peritoneal dialysis to occur over the course for the treatment of infecting, there is the advantage that structure is simple, cost is low, easy to utilize.
Accompanying drawing explanation
Fig. 1 is anti-return peritoneal dialysis catheter schematic diagram of the present utility model.
Detailed description of the invention
Composition graphs 1, a kind of anti-return peritoneal dialysis catheter of the present utility model, comprises dialysis solution ascending pipe 1, dialysis waste liquid discharge pipe 2 and back-flow preventer 3;
Described back-flow preventer 3 is connected in series with dialysis waste liquid discharge pipe 2, and two ends all keep clear; Rotating shell fragment 4 is provided with in back-flow preventer 3, the periphery of shell fragment and the inwall of back-flow preventer 3 are fitted, described shell fragment 4 comprises stiff end and movable end, length between stiff end and movable end is greater than back-flow preventer 3 inner diameter, described stiff end is connected with back-flow preventer 3 inwall, and movable end can rotate around stiff end.
Further, the cross section of inboard wall of described back-flow preventer 3 is circular.
Further, the stiff end of shell fragment 4 and back-flow preventer 3 inwall are rotationally connected; Or the stiff end of shell fragment 4 adopts flexible material, and under fluid impact, movable end can rotate around stiff end.
Dialysis solution ascending pipe one end can connect peritoneal dialysis solution, and the other end can connect the conduit of being inserted human abdominal cavity by operation, and peritoneal dialysis solution enters human abdominal cavity by dialysis solution ascending pipe; Dialysis solution discharge pipe one end connects the conduit of human abdominal cavity, and the other end is communicated with the container for holding peritoneal dialysis waste liquid.
When waste liquid of dialysing flows to from human abdominal cavity the container holding dialysis waste liquid, shell fragment 4 moves downward, and path is opened; Otherwise, if dialysis waste reflux; shell fragment 4 moves upward, shell fragment movable end also with back-flow preventer contact internal walls, formed sealing, thus reach control dialysis waste reflux object.
Claims (4)
