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

Embodiment 1

[0027] A disposable sterile syringe containing a protective sleeve, which includes a handle 1, a push rod 2, a syringe 3, a protective sleeve 4, a needle 5 and a trocar cap 6; the needle 5 is integrated with the syringe 3 and cannot be separated. This can avoid needle stick injuries caused during the process of separating the needle; the outer sleeve 4 is located outside the syringe 3; when the liquid is sucked, the needle cap does not need to be returned to protect the needle, but the outer sleeve is pushed toward the needle , Push it until it can cover the entire needle. After the nurse prepares the patient’s position and skin disinfection, perform the injection. At this time, you only need to push the outer tube in the opposite direction until the needle is completely exposed. This is good for protection The needle is in a sterile state before the injection, which helps to prevent the nurse from directly touching the needle during the process of returning the needle cap to ca...

Embodiment 2

[0030] An outer casing, which is prepared from the following parts by weight of raw materials: 20 parts of polybutylene succinate, 15 parts of polyvinyl alcohol, 8 parts of hydroxymethyl cellulose, 7 parts of polyglycolic acid, and chitosan 6 parts, 4 parts of polylactic acid, 3 parts of barium stearate, 2 parts of mica powder, 2 parts of corn starch, 1 part of sodium succinate and 1 part of silica gel. The pore volume of the silica gel is 0.60—0.85ml / g, on average The pore diameter is 4.5-7.0nm, the specific surface is 450-650m 2 / g; The particle sizes of the hydroxymethyl cellulose, chitosan, barium stearate, mica powder, corn starch and sodium succinate are all controlled at 100 mesh.

[0031] The preparation method of the above-mentioned outer sleeve includes the following steps: weigh each raw material in parts by weight for use; first, add each raw material into the agitator one by one, centrifuge at 1000 rpm for 3 minutes, and then stand for 12 hours to obtain a mixture; T...

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...
