Description
Technical field
This utility model relates to a kind of dialysis remaining needle, belongs to the medical device technical field.
Background technology
In hemodialysis, vascular access is the life line of hemodialysis patients, also is new " organ " that the patient depends on for existence.Set up and safeguard that a reliable vascular access is the prerequisite that carries out hemodialysis.Use the venous detaining needle direct arteriovenous puncture and replace central vein intubate, femoral venous catheter, have very large practicality and novelty.
At present dialysis mainly comprises two kinds with remaining needle: metal dialysis needle and straight type dialysis remaining needle.Wherein the metal dialysis needle is trapped in the patient body, causes the patient constantly to need careful draw point injury blood vessel in the dialysis overall process, and the patient must guarantee to leave standstill arm.Metal needle is larger to vascular stimulation simultaneously, and the common metal remaining needle lacks the needle point protective measure.Straight type dialysis is adopted rigid straight type pin operation technique with remaining needle, does not meet Chinese medical personnel's maneuver, needs to use specific purpose tool to blind off a line in operating process, does not generally also have the needle point protective measure.
The utility model content
The purpose of this utility model is to provide a kind of dialysis remaining needle, makes things convenient for medical personnel to operate, and improves patient's comfortableness.This remaining needle has the needle point protector, can effectively protect the operator in operating process with in the waste treatment process.
For achieving the above object, this utility model is by the following technical solutions:
A kind of dialysis remaining needle, comprise metal needle, remaining needle, draw shank, extension tube and protective casing, wherein, one end of remaining needle is the reducing expanding end, this reducing expanding end inserts an end of extension tube and tight interference fit with it, the extension tube outside in remaining needle and extension tube junction is assembled with the remaining needle base, and the other end of extension tube is with female Luer; One end of protective casing has female Luer, and this protective casing is placed in the extension tube outside and is connected with the female Luer of extension tube by this female Luer; Be provided with fish mouth shape device in this female Luer; draw shank to be located in extension tube inside by the Yu Zui hole of this fish mouth shape device; this draws shank is plastic cement material; the one end inserts in the metal needle; and stamp out a flat part in the position that is connected with metal needle and be used for the fixing metal pin; this draws the other end of shank to place the outside of protective casing, and is provided with handle at this end.
Described remaining needle base is provided with the wing lever of butterfly, is used for the scalp needle puncture maneuver that cooperates domestic medical personnel to be familiar with.
The utility model has the advantage of:
1, this utility model is fit to the operating habit of Chinese medical personnel's scalp acupuncture, can keep the relative position of metal needle and remaining needle to fix in piercing process, guarantees the puncture effect.
2, whole dialysis of the present utility model is pliable and tough, flexible with the remaining needle needle body, and staying in the patient vessel is the pip of soft macromolecule material.Can not avoid traditional puncture needle pin hole to paste the phenomenon that blood vessel wall causes Insufficience of blood flow to the blood vessel injury, the movement of patient body can not cause the unexpected variation of blood flow in the dialysis procedure, does not worry the punctures blood vessel yet.Patient's comfortableness and safety have greatly been improved.
3, the utlity model has the needle point protective measure.After puncture finishes, can quickly and easily metal needle be extracted out and be inserted in the protective casing.In operating process with in the waste treatment process, can effectively protect operator's safety.
4, the indwelling needle tail end reducing expands and the extension tube tight interference fit, and path is inner level and smooth, hinders the damaged probability of reduction blood cell in the blood transfusion process thereby reduce path.

The specific embodiment
Shown in Fig. 1～3, dialysis remaining needle of the present utility model comprises metal needle 1, remaining needle 2, draws shank 3, extension tube 4 and protective casing 5 that wherein, the material of remaining needle is flexible macromolecule material; Extension tube is the silica gel material, one end of remaining needle 2 is the reducing expanding end, this reducing expanding end inserts an end of extension tube 4 and tight interference fit with it, the extension tube outside in remaining needle 2 and extension tube 4 junctions is assembled with remaining needle base 6, this remaining needle base is provided with the wing lever 7 of butterfly, and the other end of extension tube 4 is with female Luer 8; One end of protective casing 5 has female Luer 9, and this protective casing 5 is placed in extension tube 4 outsides and is connected with the female Luer 8 of extension tube 4 by this female Luer 9; Be provided with fish mouth shape device 10 in this female Luer 9, as shown in Figure 4, this fish mouth device is the silica gel material, is made of fish mouth fixture 11 and fish mouth 12, offers Yu Zui hole 13 on the fish mouth 12; Draw shank 3 to be located in extension tube 4 inside by the Yu Zui hole 13 of this fish mouth shape device 10; this draws shank 3 to be plastic cement material; in conjunction with as shown in Figure 5; the one end inserts in the metal needle 1; and stamp out a flat part 14 in the position that is connected with metal needle 1; this draws the other end of shank 3 to place the outside of protective casing 5, and is provided with handle 15 at this end.
In the process of utilizing this utility model to puncture; medical personnel pinch the wing lever 7 clamping remaining needles 2 of butterfly and metal needle 1 with hands; the fish mouth shape device of female Luer 9 inside of protective casing closely cooperates and draws shank 3; assurance draws shank to maintain static; thereby having guaranteed in the piercing process that the relative remaining needle of metal needle is fixing is not moved, and guarantees in the piercing process safe and reliable.Remaining needle enters in the patient vessel with metal needle, and operating grip 15 will draw shank 3 to drive metal needle 1 extraction after the puncture, and flexible remaining needle 2 is stayed in the patient vessel.The movement of patient body can not cause the unexpected variation of blood flow in the dialysis procedure, does not worry the punctures blood vessel, make the patient can be in dialysis procedure the relieved comfortable posture of adjustment health and needn't worry that dialysis needle is to the injury of health and blood vessel.Simultaneously, with respect to metal needle, the biocompatibility of remaining needle is also better, reduces discomfort and the actual bodily harm of patient in the dialysis procedure.Therefore, this utility model makes things convenient for medical personnel to operate, and has greatly improved patient's comfortableness and safety.
As shown in Figure 6, after puncture finished, metal needle 1 was with drawing shank 3 to be pulled to the position of protective casing 5, and separate female Luer 8 this moment with the female Luer 9 of protective casing 5, and metal needle 1 is just stayed in the protective casing 5.Owing to draw shank 3 and flat part 14 diameters of metal needle 1 coupling part after punching press to increase, be stuck in the female Luer 9, guarantee that simultaneously metal needle 1 shrinks in the protective casing 5, effectively avoid the nurse in operating process, the risk of being stabbed by needle point.
Owing to be provided with fish mouth shape device 10 in the female Luer 9; can guarantee in the process of drawing shank 3 to pull out with metal needle 1; draw the blood of being infected with on the shank 3 when drawing shank 3 to pass through the fish mouth shape device at female Luer 9 places; be collected in the protective casing 5; can do not taken out of so that draw on the shank blood or the inner blood of extension tube thereupon; in operation and waste treatment process, can effectively protect operator's safety, simultaneously environmental contamination reduction and medical personnel's infection risk.
