Abstract

The utility model relates to a disposable pipe-washing-free vesica-type negative pressure venous indwelling needle which is a disposable venous indwelling needle capable of utilizing a negative pressure to achieve the effects of improving the puncture success rate and reducing the pain of a patient and utilizing liquid in a vesica to wash a pipe so as to save hygienic materials and reduce the infection opportunity. The elastic vesica is added on a hose of the original indwelling needle, so that blood is rapid to return when the indwelling needle is used for carrying out venipuncture, a blood vessel is prevented from being pierced, the puncture success rate is improved and the pain of the patient is reduced. A micro clip is designed into a hand hay cutter shape, so that the sealing performance of the disposable pipe-washing-free vesica-type negative pressure venous indwelling needle is strengthened. The liquid in the vesica is utilized to wash the pipe, so that the complex degree of the nursing operation is reduced, the nursing operation is simplified and the hygienic materials are saved.

Description

The disposable washing pipe vesicle formula negative pressure venous detaining needle of exempting from
Technical field
This utility model is a kind ofly can simplify the nursing technique operating process, alleviates less patient suffering, practices thrift medical and health, saves the medical material of nurses manpower.
Background technology:
At present; The used venous detaining needle of health service unit is disposable vein remaining needle (like a Figure of description 1), and this remaining needle exists blood back to be prone to piercing blood vessel slowly when carrying out venipuncture, causes the low shortcoming of puncture success rate; If can not puncture successfully by a pin; Need to change remaining needle and puncture once more, and need repeatedly washing pipe during keeping somewhere, increased infection chance in case hemostasis-coagulation blocks syringe needle; It is unimpeded in the process that keeps remaining needle, will to use a plurality of syringes to come washing pipe to keep, and causes the waste of medical material.
Summary of the invention
In order to improve puncture success rate, former disposable remaining needle (like Figure of description 1) improvement is the disposable washing pipe vesicle formula negative pressure venous detaining needle (like Figure of description 2) of exempting from present, this remaining needle overcomes the deficiency that existing remaining needle blood back when venipuncture is prone to piercing blood vessel slowly; Increased the vesicle of operability generation negative pressure; Through improving micro clip, increase the closed performance of micro clip, a GPRS correct operating methods; Success rate of venous puncture will significantly improve; And can utilize the interior liquid of vesicle to carry out washing pipe, and practice thrift medical and health, simplify NP.
The technical scheme that its technical problem that solves this utility model (like Figure of description 2) adopts is:
(1) before former disposable remaining needle Y-piece, add the oval vesicle (like Figure of description 2-1) of a diameter 1cm on the connection tube, vesicle is connected inner wall smooth with the remaining needle flexible pipe is streamlined; The vesicle material can be identical or different with flexible pipe; Elasticity is good, and inner capacities is 1.5-2ml, can operate the generation negative pressure; The remaining needle flexible pipe comprises that vesicle prolongs 3cm, total length 10-11cm at the hose length of the former disposable remaining needle of internal ratio;
(2) micro clip to former disposable remaining needle improves; Increase the closed performance of micro clip; Be designed to chopper shape (like Figure of description 2-2), edge interlock place is designed to the sawtooth pattern projection in the opposite direction of interlock each other, can operate to make behind the micro clip closed hose difficult drop-off loosening; Make the closed performance of micro clip good, thoroughly block flowing of the interior liquid of flexible pipe.
The beneficial effect of this utility model is:
The easily success of venipuncture of the pediatric patient of the volume depletion that 1, uses this utility model venous detaining needle can make a variety of causes to cause, the patient of blood vessel elasticity difference, serious dehydration.Be particularly useful for infantile scalp vein puncture.
2, the patient who uses this novel venous indwelling to be directed to the damaged patient of epidermis that a variety of causes causes, suffers from the patient of contagious disease and need promptly set up venous access because of a variety of causes directly puncture of back of sterilizing; Also easily success; Remove from separate, be the loaded down with trivial details of tourniquet; Strive for rescue time, avoid cross infection.
3, can gently press vesicle check syringe needle whether to deviate from the infusion process from blood vessel.
4, transfusion end back is full of heparin in sealing liquid or physiological saline solution in vesicle, during stopping transfusion, can push after liquid comes Syringe needle Irrigator in the vesicle micro clip to be clamped, and can prevent effectively that syringe needle is by thrombus obstruction.The pollution of having avoided original washing pipe method to be caused, and practiced thrift disposable syringe.
Description of drawings
Figure of description 1 is the disposable vein remaining needle pictorial diagram that present health service unit generally uses; Figure of description 2 is the disposable washing pipe vesicle formula negative pressure venous detaining needle design drawinies of exempting from, the 1st, can produce the vesicle of negative pressure, and the 2nd, be designed to the micro clip of chopper shape.
The specific embodiment:
This disposable washing pipe vesicle formula negative pressure remaining needle method for using of exempting from is:
1, it is subsequent use directly to pour physiological saline solution, notices that aerofluxus is thorough.
2, carry out the Strict aseptic operation by general venipuncture step.
The hand thumb forefinger is held the remaining needle needle core handle when 3, puncturing, right ring finger and centre of the palm extruding vesicle, and needle slope unclamps vesicle and forms negative pressure when getting into skin fully; When the syringe needle intravasation; The general remaining needle of blood back is rapid, and falls through sense obviously, presses down the parallel inserting needle 2mm with skin of needle handle after seeing blood back; Send into sleeve pipe, extract draw point out.
4, by conventional method paste fixing after, connect transfusion device and infuse.
5, transfusion finishes, and separates disposable transfusion device, with 5ml heparin in sealing liquid or normal saline malleation tube sealing; Open micro clip after 6-8 hour, liquid in the vesicle is extruded a part of Syringe needle Irrigator, before unclamping vesicle, micro clip is fastened hose clip; Prevent that blood from refluxing, and unclamps vesicle then.

Claims (2)

1. disposable washing pipe vesicle formula negative pressure venous detaining needle of exempting from; There is an operability to produce means for applying negative, it is characterized in that: disposable remaining needle, the Y-piece end connects an elasticity vesicle on the remaining needle flexible pipe; Inner capacities 1.5-2ml; Vesicle is connected with the remaining needle flexible pipe is streamlined, and inner wall smooth, remaining needle flexible pipe comprise that vesicle length is prolonging about 3cm on the existing remaining needle flexible pipe basis.
2. the disposable washing pipe vesicle formula negative pressure venous detaining needle of exempting from according to claim 1; The device that liquid flow in the one operability blocking-up remaining needle flexible pipe is arranged; It is characterized in that: the micro clip on the remaining needle flexible pipe is designed to chopper shape, and edge interlock place is designed to the sawtooth pattern projection in the opposite direction of interlock each other.
