Abstract

The present utility model relates to a syringe, aiming to solve problems that a drug delivery apparatus of the prior art has a complicated structure, delivery pipes that immediately contacts with human bodies has no pipe body protections and can be polluted easily, making the delivery pipes unhealthful. The syringe of the utility model comprises a piston rod, a piston head and a pipe body, the piston rod and the piston head are integrated in to a whole through a one-shot forming or adhesive bonding mode, the top end of the pipe body has a drug outlet hole, the syringe also comprises a push cavity and a pipe sleeve, the push cavity has a pipe chase, and the push cavity is connected with the pipe body which cooperates with the pipe sleeve. The syringe adopting the design above has simple structure and is sanitary and easy to use.

Description

A kind of syringe

Technical field

This utility model relates to the field of injector for medical purpose, particularly a kind of gynecological, anorectal administration injector for medical purpose.

Background technology

Shortcomings the such as at present gynecological that uses of some hospitals, anorectal administration apparatus need winch to eminence with the medicinal liquid bottle during use, and be connected with the injection head by long rubber tube as hanging bottle type, and there is inconvenient operation in this administering mode, and formulation rate is wayward; Also have a kind of doser, the dispenser pipe by being threaded io injection device, is utilized the administration of direct injection mode; solved the uppity shortcoming of formulation rate, but this doser is complicated, and does not have body protection with dispenser pipe that human body directly contacts; vulnerable to pollution, unhygienic.

Summary of the invention

It is a kind of simple in structure that the technical problems to be solved in the utility model is to provide, and uses healthy and convenient syringe.

For addressing the above problem, the technical solution of the utility model is: a kind of syringe, comprise piston rod, piston head and body, piston rod and piston head connect as one with one-shot forming or bonding mode, the body top has medicine outlet hole, syringe also includes push chamber and pipe box, and push chamber is provided with tube seat; Body matches with pipe box; Push chamber can connect as one in one-time formed mode with body and be connected.

In use, earlier pipe box is taken off from body, the tube seat on push chamber extracts piston, makes body draw medicinal liquid by the medicine outlet hole place.During dispenser, pipe box is put into push chamber, and body is placed required dispenser place, promote pipe box, pipe box is acted on the piston rod, finally promote piston medicinal liquid is injected to required dispenser place by the medicine outlet hole place.Dispenser finishes, and cleans administration apparatus, entangles body with pipe box and gets final product.The design of above-mentioned administration injection device simple in structure used healthy and convenient.

As a kind of improvement to technique scheme, described body top is semicircle, and this structural drag is less, helps body to enter the focus dispenser.

Improve as the another kind to technique scheme, described pipe box inboard is provided with projection, and projection matches with the medicine outlet hole of body.This design can make the sleeve pipe that has projection can be fastened on the body difficult drop-off.Simultaneously, medicine outlet hole can be subjected to projection protection, not vulnerable to pollution.

As to further improvement in the technical proposal, described pipe box is provided with the waveform mouth of pipe, and push chamber also is provided with the waveform shading, and the mouth of pipe and push chamber are suitable.By this structure, pipe box when body takes off, only need be rotated pipe box gently, pipe box just separates from push chamber, and is very convenient.

To sum up, adopt above-mentioned design and improvement, syringe construction is simple, and health is easy to use.

The specific embodiment

Come specific embodiment of the utility model is described below in conjunction with accompanying drawing.

Please refer to shown in Figure 1ly, described syringe construction comprises body 1, piston rod 12 and piston head 14, pipe box 2 and push chamber 3.

Body 1 top is set to hemisphere, and the center is provided with medicine outlet hole 16.Piston rod 12 and piston head 14 connect as one in one-time formed mode, and both can do the piston motion in body 1.

Pipe box 2 has the bottom of the corrugated mouth of pipe 22 and sealing, and the bottom of the mouth of pipe is provided with projection 24, and projection 24 can match with medicine outlet hole 16.

Push chamber 3 open tops, bottom and body 1 connect as one in one-time formed mode, and the bottom is provided with corrugated shading 32, and shading 32 can closely contact with the corrugated mouth of pipe 22 and match; Also be provided with 2 relative tube seats 34 on the push chamber 3, can act on piston rod 12 by tube seat 34 and in push chamber 3, move back and forth.

In use, rotate pipe box 2 gently, the mouth of pipe 22 with ripple glaze acts on mutually with shading 32, makes the mouth of pipe 22 disengagings that closely contacts with body 1 and is removed.Tube seat 34 on push chamber 3 extracts piston rod 12, makes body 1 draw medicinal liquid by medicine outlet hole 16.During dispenser, pipe box 2 is put into push chamber 3, and body 1 is inserted required dispenser place, promote pipe box 2, pipe box 2 just acts on piston rod 12, finally drives piston head 14 medicinal liquid is injected to required dispenser place by medicine outlet hole 16 places.After dispenser finishes, clean administration apparatus, entangle body 1, make the projection 24 on the pipe box 2 snap in medicine hole 16, simultaneously the mouth of pipe 22 is matched with shading 32, pipe box 2 is immobilizated on the body 1 with pipe box 2.The design of above-mentioned administration injection device simple in structure used healthy and convenient.

Above-described only is principle of the present utility model and preferred embodiment.Should be pointed out that for the person of ordinary skill of the art, on the basis of this utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
