Abstract
It is a kind of to improve the narrow disposable wearing pricker of internal arteriovenous fistula, including canula puncture needle (2)；Equipped with sacculus needle tubing (1), the needle tubing part (3) of sacculus needle tubing can pass through the needle tubing of canula puncture needle (2), two sides of pin hole (4) setting of sacculus needle tubing in syringe needle (5), sacculus (6) is arranged in pin hole (4) afterwards, rear end setting fill port (7) of sacculus needle tubing and row blood port (8), fill port (7) is connected to sacculus (6) by the channel in sacculus needle tubing, and row blood port (8) is connected to pin hole (4) by another channel in sacculus needle tubing；The syringe needle (5) of sacculus needle tubing is round end.The utility model can reach narrow positions sacculus water filling expansion narrow positions from puncture needle head by sacculus, and intervention internal arteriovenous fistula is narrow, and the maintenance of the adequacy and internal arteriovenous fistula that are conducive to dialysis uses.
Description
Technical field
The utility model relates to medical instruments, in particular to disposable wearing pricker.
Background technique
Drainage haemodialysis uses when general puncture of internal arteriovenous fistula needle only has hemodialysis.General patient's internal arteriovenous fistula
It cannot intervene in time there is a situation where narrow, blood flow is bad, when dialysis-effect is undesirable, uses internal fistula reluctantly, causes internal fistula blood
Pipe inner membrance is impaired to be aggravated, and narrow get worse is made.
Summary of the invention
Improve the narrow disposable wearing pricker of internal arteriovenous fistula the purpose of this utility model is to provide a kind of,.
A used technical solution is the utility model in order to achieve the above objectives: a kind of improvement internal arteriovenous fistula is narrow
Disposable wearing pricker, including canula puncture needle；Equipped with sacculus needle tubing, the needle tubing part of sacculus needle tubing can pass through canula puncture needle
Needle tubing, the two sides of syringe needle are arranged in the pin hole of sacculus needle tubing, and sacculus is arranged after pin hole, and water injection end is arranged in the rear end of sacculus needle tubing
Mouth and row blood port, fill port are connected to sacculus by the channel in sacculus needle tubing, and row blood port and pin hole pass through sacculus
Another channel connection in needle tubing；The syringe needle of sacculus needle tubing is round end.
Further, the fill port and syringe injection port cooperate.
Further, the central axis of the fill port is overlapped with the central axis of needle tubing.
Further, the sacculus needle tubing is equipped with the needle wing.
The utility model can reach narrow positions sacculus water filling expansion narrow positions from puncture needle head by sacculus, do
Pre- internal arteriovenous fistula is narrow, and the maintenance of the adequacy and internal arteriovenous fistula that are conducive to dialysis uses.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model preferred embodiment；
Fig. 2 is the schematic diagram of the utility model preferred embodiment.
Specific embodiment
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of improve the narrow disposable wearing pricker of internal arteriovenous fistula, including canula puncture needle 2；Equipped with ball
The needle tubing part 3 of capsule needle tubing 1, sacculus needle tubing can be arranged by the needle tubing of canula puncture needle 2, the pin hole 4 of sacculus needle tubing in syringe needle 5
Two sides, sacculus 6, the rear end setting fill port 7 and row blood port 8, fill port 7 and ball of sacculus needle tubing are set after pin hole 4
Capsule 6 is connected to pin hole 4 by another channel in sacculus needle tubing by the channel connection in sacculus needle tubing, row blood port 8；Ball
The syringe needle 5 of capsule needle tubing is round end, reduces accidental injury of the sacculus needle tubing to blood vessel.
The fill port 7 cooperates with syringe injection port, can be filled the water or be drawn water to sacculus 6 by syringe.
The central axis of the fill port 7 is overlapped with the central axis of needle tubing 3, and the two is that a straight line is convenient for pushing away after putting on syringe
The operation such as needle, water filling.
As shown in Fig. 2, the sacculus needle tubing 1 is equipped with the needle wing 9, the needle wing 9 operates sacculus needle tubing 1 convenient for operator.
In use, punctured by the syringe needle of canula puncture needle 2 in internal arteriovenous fistula narrow positions front end, then sacculus needle tubing
1 enters arrival narrow positions by canula puncture needle 2, is slowly injected by fill port 7 toward sacculus needle tubing 1 with 5ml syringe
Sterile saline makes narrow positions blood vessel dilatation by the expansion of sacculus 6, stops 30~60 seconds and sterile saline is extracted out,
Sacculus 6, which is shunk, to restore, and then sacculus needle tubing 1 is slowly extracted out, internal fistula can be used at once.
By using the utility model narrow part can be expanded, is changed to reach with early intervention narrow positions, sacculus water-filling
The maintenance of kind stenosis blood flow, the adequacy and internal arteriovenous fistula that are conducive to patients with hemodialysis uses.
