Abstract
A disposable safe hypodynia blood taking needle relates to appliances in the technical field of medical treatment. One end of a shell is detachably connected with a protecting cap while the other end of the shell is connected with a tail cap, a steel needle seat is disposed in the shell, one end of the steel needle seat is fixedly connected with a steel needle, two grooves are symmetrically arranged in the middle of the steel needle seat, a spring is connected between the steel needle seat and a tail seat, the tail seat is connected with two clamping jaws, free ends of the two clamping jaws are respectively disposed in the two grooves in the middle of the steel needle seat, a push triggering device is slidably sleeved in the shell, one end of the push triggering device extends out of an end of the shell facing towards the protecting cap, two conical pushing sheets facing towards the two clamping jaws are disposed at the other end of the push triggering device, a cavity with the inner diameter larger than the outer diameter of the steel needle seat is disposed in the push triggering device, and a steel needle hole is arranged at the bottom of the push triggering device facing towards the protecting cap. A steel needle tip is always concealed, and the possibility that medical staff is infected during blood taking operation is avoided to the greatest extent.
Description
Technical field
This utility model relates to the technical field of structures of the utensil part, particularly blood taking needle of field of medical technology.
Background technology
Widely used blood taking needle still is old-fashioned reusable type at present, and its potential threat will be the haze that medical personnel and user can't get rid of.Accidentally injure the operator and be to be difficult to the problem avoided in the global range always, so the defective of old product is obvious the fatal courses of infection of secondary user.
Summary of the invention
This utility model order is to design and a kind ofly can effectively prevents reusable disposable hypodynia safety blood taking pin.
This utility model comprises housing, and at the end detached type connection protective cap of housing, the other end connects tail-hood; The draw point seat is set in the housing between protective cap and tail-hood; End at said draw point seat is fixedly connected a draw point, it is characterized in that being symmetrical set two grooves at the middle part of said draw point seat, between said draw point seat and tailstock, connects spring; On said tailstock, connect two jaws, the free end of said two jaws is separately positioned in said two grooves at draw point seat middle part; Be nested with one at said housing inner sliding type and push away a device; The said end of sending out device that pushes away stretches out in the shell end towards protective cap; The other end is provided with two taper push jacks towards said two jaws; Said pushing away in the device cavity of internal diameter greater than draw point seat external diameter is set, steel pinhole is set in a device bottom that pushes away towards protective cap.
When needs were taken a blood sample, as long as remove protective cap, a hand-held housing was pushed a device that pushes away that is exposed to housing towards the blood sampling point a little, recalls immediately then, just accomplishes and takes a blood sample.Send out device when contacting skin owing to push away, moved to the tail-hood direction by the effect of counteracting force, two taper push jacks on it are pushed to two jaws; The free end of two jaws is opened laterally, cause two jaw free ends to leave two grooves at draw point seat middle part, at this moment; At the spring release pressure; Make the draw point seat drive draw point and prolong and push away the shell ends motion to former connection protective cap of the cavity of sending out device, push away a steel pinhole of sending out the device bottom owing to be subject to, the draw point seat can not stretch out to push away sends out a device; Send out a device and have only draw point head on it to stretch out in to push away, promptly realized blood sampling.Because the two ends of spring are connected on draw point seat and the tailstock, and spring returns by fast contraction after discharging elastic force, drive is withdrawn again to push away by draw point seat drive draw point and is sent out device again.
This utility model structure is ingenious; Easy and simple to handle; Needle point remains stealthy design, can not cause the feared state of mind, makes medical personnel to operate like a cork; Can avoid medical and nursing work person's infected probability in the operation of blood sample collection to greatest extent, like the danger of diseases such as HIV, hepatitis.Because the design of ultrashort triggering pressing type combines extra small, sharp syringe needle, pierce rapidly can reduce patient's pain significantly.Because once use, draw point will be lockable, and make blood taking needle can only use once, can guarantee the safety of user, prevent cross infection.
Be fixing spring easily; This utility model also on the said draw point seat of tail-hood, fixedly installing a quarter butt, is provided with a bulge loop on quarter butt, at the tail-hood inner bottom one horizontal brace is set; Said spring one end is nested with outside said quarter butt, and the other end is hooked on the said horizontal brace.
In addition, for the needle point that prevents draw point receives germ contamination, this utility model is plug in the connection of the inboard of said protective cap is fungi-proofing also.
Description of drawings
Fig. 1 is a kind of structural representation of this utility model.
The specific embodiment
As shown in Figure 1, this utility model is provided with the housing 1 of arc human engineering principle design, and at the end detached type connection protective cap 2 of housing 1, the other end connects tail-hood 3.
In the housing 1 between protective cap 2 and tail-hood 3 draw point seat 4 is set, the draw point 5 of end fixed connection at draw point seat 4 is symmetrical set two groove 4-1 and 4-2 at the middle part of draw point seat 4.
On the draw point seat 4 of tail-hood 3, fixedly installing a quarter butt 6; One bulge loop 6-1 is set on quarter butt 6; At tail-hood 3 inner bottom one horizontal brace 7 is set, between draw point seat 4 and tailstock 3, spring 8 is set, spring 8 one ends are nested with outside quarter butt 6; And be connected with draw point seat 4 through bulge loop 6-1, the other end is hooked on the horizontal brace 7.
Be separately positioned at the free end that connects 9,10, two jaws 9,10 of two jaws on the tailstock 3 in two the groove 4-1 and 4-2 at draw point seat 4 middle parts.
Be nested with one at housing 1 inner sliding type and push away a device 11; Push away an end of sending out device 11 and stretch out in outer end towards the housing 1 of protective cap 2; The other end is provided with two taper push jacks 12 towards two jaws 9,10; In pushing away a device 11, the cavity 11-1 of internal diameter greater than draw point seat 4 external diameters is set, steel pinhole 11-2 is set in device 11 bottom that push away towards protective cap 2.
