It is integrally formed with syringe, the boss side is equipped with push rod, and described push rod one end is equipped with pressing plate, and pressing plate is located at outside syringe
Portion, the other end are equipped with bulb, and push rod, pressing plate, bulb are integrally formed, and the push rod side is equipped with rubber stopper, rubber stopper and needle
Cylinder inner wall is fitted close, and the rubber stopper side is equipped with the spherical groove cooperated with bulb, and push rod is living by bulb and rubber stopper
Dynamic connection, the rubber stopper side are equipped with connecting rod, and the connecting rod and rubber stopper are integrally formed, and side fixation is set outside the connecting rod
There are several cards in umbrella distribution, card is made of elastoplastic；Side is equipped with puncture needle, the puncture outside the needle stand
Side is equipped with protective case outside needle.
Preferably, described connecting rod one end is equipped with the plug of truncated cone-shaped, and drug injection is more thorough when plug to inject, and avoids
The waste of drug, improves the utilization rate of drug.
It preferably, is infundibulate on the inside of the boss, funnel shaped boss is conducive to card and passes through, and it is unexpected to reduce card
Impact is formed after boss, ensure that the safety of injection.
Preferably, the syringe side is equipped with limited block, and limited block is stuck on the outside of push rod, described limited block one end and handle
Contact, the other end are contacted with pressing plate, and limited block avoids medical staff's maloperation and causes to inject by card push-in boss side
Device cancels.
Beneficial effect is shown the present invention compared with prior art:
1) after syringe use, rubber stopper is locked can not extract inside syringe, can not then reuse,
Infection caused by avoiding because of syringe secondary use ensure that the safety of injection；
2) connecting rod one end is equipped with the plug of truncated cone-shaped, and drug injection is more thorough when plug to inject, and avoids drug
Waste, improves the utilization rate of drug；
It 3) is infundibulate on the inside of boss, funnel shaped boss is conducive to card and passes through, reduces card and pass through boss suddenly
Impact is formed afterwards, ensure that the safety of injection；
4) syringe side is equipped with limited block, and limited block is stuck on the outside of push rod, and described limited block one end is contacted with handle, another
End is contacted with pressing plate, and limited block avoids medical staff's maloperation and causes syringe to cancel card push-in boss side.
