Abstract

The utility model provides a medical blood sampler, comprising a tube body and a piston which can be slid along the tube body. The utility model is characterized in that the front end of the tube body is inserted with a plug provided with a central through hole, the front end of the plug is inserted with an injecting needle, and the end of the plug is sheathed with a latex bubble. When the piston is pumped, the blood can be pumped into the latex bubble. The utility model has the advantages of simple structure, convenient operation and low cost. The medical blood sampler is disposable.

Description

Medical hemostix

This utility model relates to a kind of medical hemostix, and it belongs to a kind of medical apparatus and instruments.

Medical institutions are when doing the pathology inspection to the patient at present, often need to take patient's blood, find out disease by blood testing, and the general general syringe of apparatus of blood sampling, though syringe after using each time, all carries out conscientious sterilization, but the restriction of carelessness or condition unexpectedly, cause potential possibility still for the cross infection of virus, and the sterilization of syringe, the especially sterilization after blood sampling are a kind of work of utmost point trouble.The disposable syringe that present all-plastic is made also comes into operation on a small quantity, but its price is higher, and particularly there is lack of raw materials at present, uses and once just throwing away the too waste that seems.

It is a kind of both convenient that the purpose of this utility model is to provide, cheap again, and can stop the medical hemostix of crowd's virus cross infection.

The purpose of this utility model is to realize like this.It comprises cylindrical shell and along the piston that slides in the cylindrical shell, its principal character is the plug that has central through hole of front end grafting at cylindrical shell, and the front end of plug can be pegged graft with the injection syringe needle, latex bubble of the end cover of plug.Twitch piston, just blood can be extracted in the latex bubble.

The raw material that constitutes plug portion can be nontoxic rigid plastics, also can be nontoxic hard rubber or glass or sterile-processed timber.

This utility model has following characteristics: 1, because the plug that is installed in barrel front end can be pegged graft easily and be dialled down, and adopt raw material less, therefore can be used as disposable use.Avoided the cross infection of crowd's virus.2, because cylindrical shell does not contact with blood with piston, therefore need not to carry out disinfection, alleviated nurse's workload greatly.And the type of glass that cylindrical shell and piston adopted can relax greatly, and for easy processing, more cheap glass all can adopt, thereby can reduce manufacturing cost.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is this utility model structural representation.

Fig. 1 is an embodiment of the present utility model, it is by cylindrical shell 1, piston 2, plug 3, latex bubble 4, rubber cushion 5, pressure cap 6 is formed, piston 2 can be along sliding in the cylindrical shell 1, plug 3 is plugged on the front end of cylindrical shell 1, plug 3 is provided with the ring-type rubber cushion 5 that seals usefulness with the junction of cylindrical shell 1, plug 3 has central through hole, usefulness 0 of end cover of plug 3,1-0, the latex bubble 4 that the high-quality latex that 2mm is thick is made, the round table-like jut of the plug 3 front ends medical needle of can pegging graft, also hollow needle directly can be embedded in plug head, use the back to destroy with plug, pressure cap 6 is main with fixing or compressing rubber cushion 5, it is connected as spiral with cylindrical shell 1, also can make can firmly lay the groove of rubber cushion 5 and save pressure cap in cylindrical shell.Plug 3 middle part thicker parts divide also can make hollow, and material is utilized transparent material, and, adopt blood wherein during operation with scale the outside, and do not enter the latex bubble.

Claims

1, a kind of medical hemostix, it comprises cylindrical shell and along the piston that slides in the cylindrical shell, it is characterized in that: at plug that has central through hole of front end grafting of cylindrical shell, the front end of plug can with injection syringe needle peg graft (perhaps hollow needle directly being embedded in plug head), latex bubble of the end cover of plug, the junction of plug and cylindrical shell is provided with the ring-type rubber cushion of sealing usefulness.

2, by the described medical hemostix of claim 1, the material that it is characterized in that constituting plug portion can be nontoxic rigid plastics, also can be nontoxic hard rubber or glass or sterile-processed timber.

3, by the described hemostix of claim 1, it is characterized in that described plug intermediate portion can make hollow, material is utilized transparent or semitransparent material, and outside with scale.
