Disposable sterile syringe comprising protection sleeve tube

Abstract

The invention belongs to the field of medical equipment and discloses a disposable sterile syringe comprising a protection sleeve tube. The disposable sterile syringe comprises a handle, a push rod, a syringe, the protection sleeve, a needle and a sleeve needle cap. The disposable sterile syringe is characterized in that the needle and the syringe are integrated and cannot be separated; the outer sleeve tube is located outside the syringe; the outer sleeve tube is pushed towards the direction of the needle so as to cover the integral needle when the suction of the medicine liquid is achieved. According to the disposable sterile syringe comprising the protection sleeve tube, the structure is simple, the use is convenient, the needle puncture caused by needle cap back sleeving can be effectively avoided, the aseptic condition of the needle can be convenient to maintain before injection, the needle puncture caused by the needle separation can be avoided after the injection, and the certain application value is achieved.

Description

[0001] technical field [0002] The invention belongs to the field of medical equipment and relates to a disposable aseptic syringe including a sheath tube; the invention also relates to a sheath tube and a preparation method thereof. [0003] Background technique [0004] Needlestick injury is one of the occupational diseases in medical and nursing work, which can cause a variety of blood-borne diseases. Nurses are the group with the highest incidence of needlestick injuries in hospitals. Therefore, how to avoid frequent needlestick injuries has important clinical significance. [0005] The main causes of needlestick injuries are: After the nurse finishes a certain operation, she fails to return the syringe needle to the needle cap, and puts it aside at will, resulting in stabbing herself or others during the next operation; When returning the needle cap, it is more casual, not enough attention is paid, and the finger is stabbed; The used syringe needle was not immedi...

AI Technical Summary

Problems solved by technology

But the problem that exists at present is: in the clinical nursing work process, the syringe is often placed in the treatment tray temporarily after the medicinal liquid is sucked, and the injection can only be performed after the patient is helped to take the correct body position and the skin is disinfected. Nurses are likely to contaminate or be stabbed by needles during the process of recapping. If the needle cap is not recapped, needle exposure cannot be avoided. Long-term exposure of needles will lead to two consequences. One is that the originally sterile needle is contaminated , the second is an accidental needle stick injury

In order to avoid the contamination and needle stick injury caused by returning the needle cap, the current clinical nursing practice has prohibited returning the needle cap at this time, which cannot solve the problem of prolonged exposure of the needle before injection

In addition, the performance stability of the retraction technology of the syringe is poor during use, and problems such as premature excitation of the needle, incomplete excitation, or liquid leakage often occur during use.
