Description

Cassette full-automatic injecting pen

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of cassette full-automatic injecting pen.

Background technology

In medical institutions, finished often for patient infusion by medical personnel, the operating process of its injection is numerous and diverse, and the time spent is longer, but in some first aid field, the time often is exactly life, so, automatic inserting needle and the injection technique that automatically pushes away medicine is arisen at the historic moment." automatic injection technology " refer to without medical personnel operation or instruct, by non-medical staff such as soldier in the battlefield, patient's injection technique of inside and outside hospital, injecting voluntarily.Automatic injecting needle is equipped in a few countries such as Sweden, the U.S., France, Russia small lot and is engaged in the specialized force that anti-chemical, bacteriological protection, protection against atomic weapons kill and wound, and is used for the interim first aid in battlefield.Be applied to the injection that also is only limited to insulin or polypeptide drug of common medical field, because the structural limitations of this syringe, it is confined to dosage less than the micro-injection of 0.5ml, so the scope of application of this syringe is limited greatly, be applicable to minority medicine and local field, and the structure of this automatic injecting needle is very complicated, and production cost is very high, and the home sale price of an automatic injecting needle is at 200～500 yuans.Existing automatic injecting needle because its structure is too complicated, is difficult to processing and manufacturing, and it is also not too convenient to use, and similarly syringe can't the mold manufacturing in actual production is made; In addition, the very important point is that similar syringe also may inject human body with micro-air remaining in the injection needle, forms aeroembolism, the infringement human body.

Summary of the invention

The purpose of this utility model provides a kind of cassette full-automatic injecting pen, and it is too complicated to have solved the structural design that exists in the prior art, is difficult to processing and manufacturing; Also micro-air remaining in the injection needle may be injected human body, the problem of infringement health.

The technical scheme that this utility model adopts is, a kind of cassette full-automatic injecting pen comprises a body and pin oversheath, and a body and pin oversheath are threaded connection, and in the body bottom through hole button are installed; The pin oversheath is equipped with the pastille clamped bottle with a body internal cavities, and pastille clamped bottle bottleneck end is equipped with the twolip injection needle, and twolip injection needle periphery is set with the aerofluxus needle guard, and the top of pin oversheath is provided with helmet;

Body bottom inner surface has annular ridge, and the port internal diameter of button is consistent with the annular ridge internal diameter; Body internal cavities is equipped with hook and lock push rod, and the hook lower end is hinged with the lock push rod, and the lock push rod is connected with the plug of pastille clamped bottle bottom, is provided with button spring between button and the annular ridge, locks between push rod and the annular ridge to be provided with the lock push rod spring.

The beneficial effects of the utility model are, are used for the intramuscular injection medicinal liquid, have realized the multiple injection use, and designs simplification is made easily, can discharge micro-air in the needle tubing, use safer, conveniently.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a cassette full-automatic injecting structure of the present utility model is, comprises a body 5 of the upper half and the pin oversheath 9 of lower half, and a body 5 and pin oversheath 9 are threaded connection, in the body 5 bottom through holes button 1 is installed, surface, outer, a body 5 bottom is equipped with pen hanging 4; Pin oversheath 9 is equipped with pastille clamped bottle 8 with a body 5 internal cavities, pastille clamped bottle 8 tops (bottleneck end) are equipped with twolip injection needle 10, twolip injection needle 10 peripheries are set with aerofluxus needle guard 11, twolip injection needle 10 does not pierce through pastille clamped bottle 8 bottleneck plugs before the injection, compressing aerofluxus needle guard 11 is just so that twolip injection needle 10 pierces through pastille clamped bottle 8 bottleneck plugs during injection, the top of pin oversheath 9 is provided with helmet 13, and helmet 13 is provided with cushion pad 12 with the contact surface of aerofluxus needle guard 11;

Body 5 bottom inner surface are provided with an annular ridge, are used for the hook location to linking up with 3, and the port internal diameter of button 1 is consistent with the annular ridge internal diameter; Body 5 internal cavities are equipped with hook 3 and lock push rod 7, the hook-type projection of linking up with outer, 3 upper end can be hooked on the annular ridge, it is hinged with lock push rod 7 to link up with 3 lower ends, lock push rod 7 is used for being connected with the plug 14 of pastille clamped bottle 8 bottoms, be provided with button spring 2 between button 1 and the annular ridge, be provided with lock push rod spring 6 between lock push rod 7 and the annular ridge.

The hook-type projection of hook 3 outer, upper end before injection is hooked on the annular ridge, and the hook-type projection of hook 3 and annular ridge are thrown off during injection.

The lower end of lock push rod 7 is connected by spiral way with pastille clamped bottle 8 bottom plugs.

Button 1 and a body 5 bottoms are by locating slot installation site socket as required, i.e. opening groove position and latching slot position, and opening groove and latching slot UNICOM, but the position is different, and different from the control effect of a body 5 to button 1.

Cassette full-automatic injecting pen of the present utility model is threaded to opening with button 1 during use, and syringe needle perpendicular alignmnet injection site keeps stable.Press the button 1, after lock push rod 7 syringe needles inject human body, after the assurance medicinal liquid all injects human body, extract twolip injection needle 10, can automatically finish inserting needle and injection.It is simple to reset when reusing, and the pastille clamped bottle is easy to loading and unloading.

Aerofluxus needle guard 11 promotes aerofluxus needle guard 11 with degassing function, can drive twolip injection needle 10 and pierce through plug, and medicinal liquid can be extruded with micro-pressure the air of trace in the needle tubing, has avoided air to enter human body to the injury of human body.

The using method of cassette full-automatic injecting pen of the present utility model is:

One, preparation: be ready to following article before the injection: cassette full-automatic injecting pen, the pastille clamped bottle of dimension, the aseptic twolip injection needle of disposable use.

Two, cassette full-automatic injecting pen is installed:
