Abstract

The invention provides a disposable syringe. The disposable syringe comprises a sleeve, a push rod, a syringe needle and a piston, wherein the piston is connected to the lower end of the push rod, and is arranged in the sleeve together with the push rod in a sleeving way; the front end of the sleeve protrudes to form a medicinal liquid supply port; the syringe needle is separately combined with the medicinal liquid supply port; the bottom of the push rod is provided with a cavity of which the shape and size correspond to the syringe needle. After use, the syringe needle can be pressed into the corresponding cavity in the bottom of the push rod, so that the syringe needle is prevented from being taken out easily, repeated use of the disposable syringe can be prevented effectively, and the health of patients is protected effectively; meanwhile, potential harm due to random placement of the syringe needle after use is avoided.

Description

A kind of disposable syringe

Technical field

The present invention relates to a kind of syringe, relate in particular to a kind of disposable syringe.

Background technology

Syringe is a kind of quite common medical supplies, and it is that drug injection is entered in patient body, to reach treatment effect. Generally speaking, healthcare givers first introduces medicine in syringe, and then by the syringe needle on syringe, this drug injection is entered in patient body.

With regard to the aspect using with regard to reality, traditional syringe has many potential risk factors. In by improper use, it will cause very serious injury and bad impact on patient's health.

Wherein, a main problem is, traditional syringe and easily there is reusable problem, its reason is, traditional syringe structurally and cannot avoid reusing, therefore still reuse syringe easily of personage intentionally.

For instance, when in injector to inject medicine to patient body, this patient's blood, residual medicine, bacterium, virus or other morbid substances all likely remain on syringe or its syringe needle. In the time that same syringe is used again at second patient, therefore second patient may infect to last position patient's germ.

If first patient infected by virus, second patient may be because share syringe with first patient so, and infect to identical virus, or second patient also likely therefore and the medicine that first patient used produces allergic reaction.

Further, if simple with regard to the outward appearance of syringe, healthcare givers be difficult to judge its be whether one by used syringe.

Summary of the invention

The object of the invention is to overcome the defect of prior art, a kind of disposable syringe of security is provided, after using, can, by syringe needle by compressing into the corresponding cavity in push rod bottom, make it be difficult for taking out, effectively avoid thus syringe to be reused.

For achieving the above object, the invention provides a kind of disposable syringe, comprise sleeve, push rod, syringe needle and piston, described piston is connected to the lower end of push rod, be contained in described sleeve with pushing rod sleeve, the outstanding liquid supply opening that forms of described barrel forward end, described syringe needle is incorporated into described liquid supply opening place separably, and described push rod bottom is provided with a shape, size and the corresponding cavity of described syringe needle.

Further, described syringe needle is made up of needle body and needle hub; To two ends, its internal diameter diminishes the middle body of described needle hub gradually.

Further, described sleeve subscript is marked with scale, for confirming the capacity of liquid medicine injection.

Beneficial effect of the present invention: disposable syringe of the present invention; simple in structure; be easy to produce; can be by syringe needle by compressing into the corresponding cavity in push rod bottom after using; make it be difficult for taking out, can effectively prevent reusing of disposable syringe, effectively protect sufferer health; also avoided using syringe needle later arbitrarily to place, caused potential harm simultaneously.

Brief description of the drawings

Fig. 1 is the cutaway view of disposable syringe of the present invention;

Fig. 2 is the structural representation of syringe needle.

Detailed description of the invention

Describe mechanism of the present invention and operation principle in detail below in conjunction with accompanying drawing. For better explanation the present embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable. The corresponding same or analogous parts of same or analogous label.

Shown in Fig. 1-2, the invention provides a kind of disposable syringe, comprise sleeve 1, push rod 2, syringe needle 3 and piston 4, described piston 4 is connected to the lower end of push rod 2, be sleeved in described sleeve 1 with push rod 2, the outstanding liquid supply opening 5 that forms of described sleeve 1 front end, described syringe needle 3 is incorporated into described liquid supply opening 5 places separably, and described push rod 2 bottoms are provided with a shape, size and the corresponding cavity 6 of described syringe needle 3. Described syringe needle 3 is made up of needle body 31 and needle hub 32, to two ends, its internal diameter diminishes the middle body of described needle hub 32 gradually, liquid supply opening 5 and needle hub 32 are made up of the plastics or the resin that possess certain elastic force, can make liquid supply opening 5 and needle hub 32 mutually combine closely and maintain air-tightness. In addition, described sleeve 1 subscript is marked with scale, for confirming the capacity of liquid medicine injection. Using after syringe and the syringe needle 3 that is placed in syringe front end can taken off, by syringe needle 3 by the cavity 6 of compressing into push rod 2 bottoms, make it be difficult for taking out, thereby can effectively prevent reusing of disposable syringe, also avoided using syringe needle later arbitrarily to place, caused potential harm simultaneously.

Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without also giving exhaustive to all embodiments. All any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in the protection domain of the claims in the present invention.
