The skin prick test slope pushing block elastic pin needle comprises a needle head, a needle seat, a slope pushing rod and a shell. A transverse hole and a vertical hole which are formed at a certain angle and communicated with each other are formed in the shell. The needle seat is arranged in the vertical hole. The slope pushing rod is arranged in the transverse hole. A slope is arranged at the tail of the needle seat. A dovetail groove is formed in the slope and matched with a protrusion of the slope pushing rod, the protrusion can only slide in the dovetail groove, thus, the slope pushing rod moves in the transverse hole to make the needle seat move in the vertical hole, the tail of the slope pushing rod stretches out of the shell and is provided with a pushing disc, a thick spring is arranged between the pushing disc and the shell, the thick spring can be compressed by pushing the pushing disc, and the thick spring can automatically rebound after the pushing disc is released.
Description
Technical field
The present invention relates to a kind of pin, particularly relate to a kind of skin prick experiment inclined-plane pushing block bullet pin.
Background technology
The test of existing human body skin allergy, mainly tested by skin prick and obtain desired data, what mainly adopt clinically at present is skin prick anaphylactogen---sterilization patient bilateral forearm, inner forearm anaphylactogen medicinal liquid (about 20 kinds) on 3-5cm drips, and drip have Skin prick testing and normal saline negative control, in the medicinal liquid central authorities vertical prick skin of disposable aspiration needle to subcutaneous, observe 20 minutes, comparing with histamine group and saline group, there is position and size in record welt.But for operator, especially abecedarian, syringe needle thrusts degree of depth Chang Buneng to be held, and thrusts shallow, and skin can not be punctured, and may cause false-negative result.Thrust dark, pain is strong, thrusts skin corium, causes hemorrhage, will affect test result, thus operator be can not let go when operating, and makes detection efficiency excessively slow.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and thrust the skin prick experiment inclined-plane pushing block bullet pin that skin depth is easily held, pain is few, test result is accurate, detection efficiency is high.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of skin prick experiment inclined-plane pushing block bullet pin, comprise syringe needle, needle stand, surface push-rod and housing, be provided with in housing be in certain angle and the cross-drilled hole be interconnected and vertical core, needle stand is provided with in vertical core, surface push-rod is provided with in cross-drilled hole, needle stand afterbody is provided with an inclined-plane, inclined-plane has dovetail groove, matching with the projection of surface push-rod makes projection can only slide in dovetail groove, the movement in cross-drilled hole of such surface push-rod can make needle stand move in vertical core, surface push-rod afterbody stretches out housing and is provided with push-plate, be provided with bulky spring between push-plate and housing to make to promote can automatically rebound after push-plate can compress bulky spring relieving push-plate,
Needle stand head is provided with a hole and is provided with syringe needle, the movement of needle stand can make syringe needle stretch out or retraction housing, vertically with the hole that syringe needle is installed be provided with a pin-and-hole, a resilient key is provided with in pin-and-hole, resilient key comprises head pin and end pin, be provided with hairspring between head pin and end pin and make distance variable between head pin and end pin, during syringe needle retraction housing, hairspring is pressed in end pin on housing by compressing head pin and is pressed in and syringe needle makes syringe needle can follow needle stand move together, housing side is also provided with is reduced end pin in the hairspring pusher head pin access aperture compressed when a hole makes syringe needle move to certain position with needle stand and under gravity or vibrating state, is departed from needle stand by syringe needle to the pressure of syringe needle, needle stand is extremely made entirety not can be movable relatively by lock simultaneously,
In case side face, be also provided with one push away post, pushing away post to be connected with housing by spring, can end pin to be pressed in the head pin introduction hole in hole when post moves in hole to put on the syringe needle of needle stand needle stand simultaneously to unlock to move syringe needle can be shunk back housing under bulky spring effect by pushing away.
The beneficial effect that the invention provides a kind of skin prick experiment inclined-plane pushing block bullet pin is: design like this, promotion surface push-rod easily can promote syringe needle slowly and thrust skin, user is made to have more comfortable experience, the effect that inclined-plane plays increases rise makes more easily to control the speed and strength of pin, what needle stand was designed to changeable type can change syringe needle very easily, different people can be avoided like this to use and to cause cross infection, spring is used to reply, easy to use, and the pressure being subject to spring increases the degree of depth and dynamics that feel can control pin so very easily greatly, improve the comfort level of user.
Further, as preferably, surface push-rod is with to push away post vertical, and can be expressed to that two parts cause like this can not be locked simultaneously.
Further, end pin is inclined-plane near syringe needle face, so conveniently syringe needle is put into needle stand.
