Description

Apparatus for purifying blood extracorporeal circulation vein loop
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of apparatus for purifying blood extracorporeal circulation vein loop that is used for hemodialysis.
Background technology
Normally adopt blood dialysis in the method for medically treating person having renal failure.Hemodialysis is according to the membrane equilibrium principle, blood samples of patients is guided to external, gets back in the body after the effect through dialysis apparatus and dialysis solution, reaches and removes harmful substance in the body, the purpose of the interior desired substance of added body.As the path of blood in extracorporeal circulation, the safety in extracorporeal circulation blood circuit loop and the adaptability important that seems.The extracorporeal circulation vein loop of existing apparatus for purifying blood; Mainly form by parts such as dialysate connector, sampling joint, little flow-stopping clip, lock-on connection, lock-on connection lid, dropping funnel, big flow-stopping clip, swivel joint seat, swivel joints; Use such loop owing to prevent counter-flow designs preferably, therefore the safety to patient has certain hidden danger all the time.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned existence, provide a kind of simple in structure, safety good, easy to operate apparatus for purifying blood extracorporeal circulation vein loop.
The technical scheme that this utility model is adopted in order to achieve the above object is: a kind of apparatus for purifying blood extracorporeal circulation vein loop; It comprises dialysate connector, sampling joint, little flow-stopping clip, lock-on connection, dropping funnel, big flow-stopping clip, swivel joint seat and swivel joint; Wherein dialysate connector connects the dropping funnel with threeway lid through upper conduit; On this upper conduit, also be connected to the sampling joint, other two interfaces of said threeway lid all are connected with lock-on connection through conduit, and between lock-on connection and threeway lid, are provided with little flow-stopping clip; Dropping funnel connects the swivel joint seat through downcomer; Also be provided with big flow-stopping clip on this downcomer, the swivel joint seat is provided with swivel joint, it is characterized in that also being provided with on the said upper conduit anti-backflow device.
According to the apparatus for purifying blood extracorporeal circulation vein loop described in this utility model, it is characterized in that said each lock-on connection is stamped the lock-on connection lid; The swivel joint lid is stamped in said swivel joint top; Said anti-backflow device is located on the upper conduit that adopts between joint and the dialysate connector; Said anti-backflow device is the check valve that medical silica-gel or medical macromolecular materials are processed.
Therefore this utility model makes the blood in the whole loop can not flow backwards in dialysis apparatus through between dialysate connector and employing joint, setting up an anti-backflow device, has more effectively protected patient's safety, reaches the purpose of safety dialysis.So the utlity model has advantages such as simple in structure, with low cost, reasonable in design, easy to operate, that safety is good, have market prospect preferably.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure: the 1-dialysate connector; The 2-anti-backflow device; The 3-upper conduit; The 4-joint of sampling; The little flow-stopping clip of 5-; The 6-lock-on connection; 7-lock-on connection lid; 8-threeway lid; The 9-dropping funnel; The big flow-stopping clip of 10-; The 11-downcomer; 12-swivel joint seat; The 13-swivel joint; 14-swivel joint lid.
The specific embodiment
To combine accompanying drawing that the technical scheme of this utility model is further specified below, but this utility model is not limited in following embodiment.
As shown in Figure 1: apparatus for purifying blood extracorporeal circulation vein loop, it comprises dialysate connector 1, sampling joint 4, little flow-stopping clip 5, lock-on connection 6, dropping funnel 9, big flow-stopping clip 10, swivel joint seat 12 and swivel joint 13.Wherein dialysate connector 1 connects the dropping funnel 9 with threeway lid 8 through upper conduit 3; On this upper conduit 3, also be connected to sampling joint 4 and anti-backflow device 2 with forward unlatching, reverse closing function; The wherein check valve of anti-backflow device for adopting medical silica-gel or medical macromolecular materials to process, and this check valve adopting between joint 4 and the dialysate connector 1.Other two interfaces of said threeway lid 8 all are connected with lock-on connection 6 through conduit, all are covered with lock-on connection lid 7 on each lock-on connection 6, and between lock-on connection 6 and threeway lid 8, are provided with little flow-stopping clip 5.The lower end of dropping funnel 9 connects swivel joint seat 12 through downcomer 11, also is provided with big flow-stopping clip 10 on this downcomer 11, and swivel joint seat 12 is provided with swivel joint 13, is stamped swivel joint lid 14 on the swivel joint 13.This loop prevents effectively that through between sampling joint 4 and dialysate connector 1, setting up a check valve of being processed by medical silica-gel or medical macromolecular materials blood is back in the dialysis apparatus, has guaranteed safe dialysis, makes patient's safety guarantee be improved.Secondly the operational approach of this utility model is consistent with general circuit operation method, and is therefore easy to operate.
