In modern medical treatment, the syringe is the medical instrument that medical personnel are indispensable, the wide frequency of application range is high, syringe needle and nipple's connected mode mainly has two kinds, one kind is the cooperation of nipple's conical surface and the taper hole of syringe needle, the syringe needle directly cartridge is on the nipple, the nipple is provided with the external screw thread in addition, be provided with the internal thread on the syringe needle, through inside and outside screw-thread fit, screw the syringe needle on the nipple, because the connection of the latter is more firm, so more commonly used, when the syringe is used up, medical personnel need disassemble the syringe, take off the syringe needle, put into sharp machine box, the syringe needle that leans on the cooperation of nipple's conical surface and the taper hole of syringe needle can directly pull out in the process of taking off the syringe needle, but the syringe that fixes through screw-thread fit needs medical personnel to screw off the syringe needle with the hand, medical personnel probably pricked when screwing the syringe needle with the hand, since needles are used and may carry blood or other body fluids from the patient, which increases the risk of infection to the medical staff, there is a need for a device that will not allow the medical staff to remove the needle by directly contacting the needle with their hands.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the background art and provide a syringe needle collecting device.

A syringe needle collecting device comprises a collecting barrel and a collecting barrel cover, wherein the collecting barrel cover is arranged on the collecting barrel;

the collecting barrel cover comprises a collecting barrel cover main body, a sliding block, a push handle, a cover plate rotating shaft and a return spring, wherein the sliding block is arranged on the collecting barrel cover main body through a sliding groove;

the upper surface of the collecting barrel cover main body is provided with a triangular opening, the top end of the triangular opening is in arc transition, and the side surface of the triangular opening is provided with a first anti-skid protrusion;

rectangular bulges are arranged on two sides of the sliding block, and a second anti-skid bulge is arranged on the front part of the sliding block;

the rectangular bulge is matched with the sliding groove for use, and the sliding block can freely slide in the sliding groove through the rectangular bulge;

specifically, the cover plate horizontally rotates by taking the cover plate rotating shaft as a shaft;

specifically, the cover plate can completely cover the triangular opening on the collecting barrel cover main body;

the outer side wall of the collecting barrel is provided with a hook;

the hook is hinged on the outer side wall of the collecting barrel through a hinge shaft.

The working principle and the process of the invention are as follows:

when the syringe is used, a medical worker opens the cover plate, inverts the used syringe, inserts the needle into the triangular opening on the collection barrel cover body, tightly attaches the connection part of the syringe nipple and the needle to the arc transition area at the top end of the triangular opening, presses the push handle with fingers to push the push handle forwards, the push handle and the slide block move forwards along the sliding groove, the front end of the slide block is tightly attached to the connection part of the syringe nipple and the needle, the first anti-slip bulge and the second anti-slip bulge play a role in increasing friction force, then the medical worker presses the push handle with one hand, twists the syringe needle cylinder with the other hand, releases the push handle until the syringe needle is separated from the syringe needle cylinder, then restores the initial position of the slide block under the action of the reset spring, the needle falls into the collection barrel, and covers the cover plate for next.

The utility model has the advantages that:

the utility model has the advantages of being simple in structure and convenient in operation, safe and reliable makes medical personnel when disassembling the syringe needle, and hand and syringe needle do not take place direct contact to avoided the syringe needle to stab medical personnel, reduced medical personnel's the risk of being infected, protected medical personnel's personal safety, improved medical personnel's work efficiency, be fit for extensive popularization and application.
