Abstract
The utility model provides a self-destructing type disposable aseptic transfusion device, comprising a main needle head composed of the head part and the tail part of the main needle head and the, a transfusion tube connected with the tail part of the main needle head and a dripping kettle connected with the transfusion tube. Plug-in connection is arranged between the head part and the tail part of the main needle head, and the head part and the tail part are separable. An expansion plug with a hole is arranged in the lower kettle neck of the dripping kettle. On the moment the main needle head is extracted from a medical liquid bottle, via a resistance between a cone at the head part of the main needle head and the stopper of the medical liquid bottle, the head part of the main needle head is discarded in the medical liquid bottle, and the needle head can not be used repeatedly. Further since the expansion plug is arranged in the dripping kettle, the hole in the expansion plug is blocked due to the result that expansion plug absorbs water and expands when a plurality of medical liquid is transfused, the entire transfusion device is ineffective, and the aim of disposable use is really obtained.
Description
Technical field
This utility model relates to a kind of medical Transfusion device, particularly relates to a kind of for preventing that disposable transfusion device is repeated to use the self-destructed disposable that causes cross infection to use abacterial transfusion system.
Background technology
At present the disposable transfusion device that generally uses of China is purchased, is peddled and reusable phenomenon is very serious.Though the national parties concerned have taked many measures, but for the low lower medical personnel of hospital, clinic and quality of management, the incident of reusing disposable transfusion device in order to try to gain our unit or individual interest in a large number still remains incessant after repeated prohibition, the used disposable transfusion device of a large amount of collections of particularly illegal businessman is sold through simple process, repacking back, causes very big harm to society.The phenomenon of vast rural area and undeveloped country's repeated use disposable transfusion device is commonplace, the problem of cross infection happens occasionally, increased propagation undoubtedly, greatly damaged and reduced people's body constitution as multiple communicate illnesss such as SARS virus, bird flu virus, HIV (human immunodeficiency virus) (Human Immunodeficiency Virus).
The utility model content
It is a kind of for preventing that disposable transfusion device is repeated to use the self-destructed disposable that causes cross infection to use abacterial transfusion system that the purpose of this utility model is to provide.
For achieving the above object, the technical scheme that this utility model adopted is: this utility model comprise the main syringe needle of forming by main syringe needle head 2 and afterbody 1, the tube for transfusion 4 that is connected with main syringe needle afterbody 1, be connected with tube for transfusion 4 drip kettle 5, it is characterized in that: described main syringe needle head 2 is connected for plug-in type with afterbody 1 and is separable, is provided with the expansible stopper 6 that wherein has hole 8 in the following kettle neck 7 of described kettle 5.
Described main syringe needle head 2 is cone 3 structures.
This utility model compared with prior art has the following advantages: the one, and main syringe needle is extracted the moment of medicinal liquid bottle, utilizes the forecone of main syringe needle and the resistance of medicinal liquid bottle stopper, and the head of main syringe needle is discarded in the medicinal liquid bottle, and main syringe needle can not be reused; The 2nd, owing to insert an expansible stopper in dripping kettle, behind several bottle liquid medicines of being totally lost, because the result of expansible stopper imbibition, the hole in the expansible stopper is blocked, and makes the transfusion device global failure, really reaches disposable purpose.

Fig. 2 is the cutaway view of this utility model master syringe needle.
Fig. 3 is the cutaway view of this utility model master syringe needle afterbody.
Fig. 4 is the cutaway view of this utility model master syringe needle head.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model and operation principle are described further.
With reference to accompanying drawing, this utility model comprises main syringe needle, the tube for transfusion 4 that is connected with main syringe needle afterbody 1, a kettle 5 that is connected with tube for transfusion 4, described main syringe needle is made up of the head 2 of main syringe needle and afterbody 1 two parts of main syringe needle, its head 2 is connected for plug-in type with afterbody 1 and is separable, main syringe needle head 2 is cone 3 structures, be provided with the expansible stopper 6 that wherein has hole 8 in the following kettle neck 7 of described kettle 5, expansible stopper 6 adopts the health fiber, water-absorbing resin or expanded rubber etc. meet the material of health care standard and make, its may command speed of expansion makes expansible stopper 6 at 12 hours rear enclosed medicine liquid channels.
During use, main syringe needle is inserted the transfusion of medicinal liquid bottle, after medicinal liquid is totally lost, extract main syringe needle, utilize the frictional resistance of cone 3 and medicinal liquid bottle plug of the head 2 of main syringe needle, the head 2 of main syringe needle is discarded in the medicine bottle, main syringe needle can not be reused, the afterbody 1 of remaining main syringe needle can't insert the medicinal liquid bottle again.Need continuously defeated many bottle liquid medicines as patient, the head 2 that the main syringe needle afterbody of pulling up 1 is connected again standby main syringe needle continues to use.Drip in the kettle 5 when medicinal liquid enters, expansible stopper 6 is invaded medicinal liquid and is begun slowly to expand, behind several bottle liquid medicines of being totally lost, because the result of expansible stopper 6 imbibitions, the hole 8 in the expansible stopper 6 is blocked, and makes the transfusion device global failure, can't continue again to use, really reach disposable purpose.
Claims (2)
1, a kind of self-destructed disposable uses abacterial transfusion system, comprise the main syringe needle of forming by main syringe needle head (2) and afterbody (1), the tube for transfusion (4) that is connected with main syringe needle afterbody (1), be connected with tube for transfusion (4) drip kettle (5), it is characterized in that: described main syringe needle head (2) is connected for plug-in type with afterbody (1) and is separable, is provided with the expansible stopper (6) that wherein has hole (8) in the following kettle neck (7) of described kettle (5).
