Abstract

The utility model relates to a disposable injector needle disfiguring device and belongs to the technical field of medical appliances; the device is characterized in that: one end of a case body has an opening, and a drawing box which is suitable for the inner cavity of the case body is sheathed in the case body, a sleeve pipe which is communicated with the inner cavity of the case body and the cross section of which is rectangle is arranged in the middle of an upper plate surface of the case body, and the upper end surface of the sleeve pipe is opened with an through hole; a pressure plate is connected with the upper end of a supporting pole, and the lower end of the supporting pole penetrates through the through hole at the upper end surface of the sleeve pipe for connecting a limit plate with a cutting knife in the sleeve pipe, and a supporting spring is sheathed on the supporting pole between the pressure plate and the upper end surface of the sleeve pipe; a square beam with a cutting groove which is suitable for the cutting knife is connected between the left and right pipe walls at the inner part of the sleeve pipe, a needle head inserting hole corresponding to the square beam is opened on the pipe wall at the rear part of the sleeve pipe, and a downward-pointing triangle needle head separating bayonet is opened at the lower part of the needle head inserting hole. The disfiguring device has simple structure, convenient and safe usage, easy clean and sterilization, and long service life; when medical personnel manually carry out needle head disfigurement, the hand skin can not be punctured.

Description

The disposable syringe syringe needle device that unmakes

Technical field

This utility model belongs to technical field of medical instruments, specifically the disposable syringe syringe needle device that unmakes.

Background technology

According to country to hospital's management expectancy of protecting from infection, should unmake, sterilize syringe needle and syringe immediately after disposable syringe is finished using,, prevent that especially illegal businessman from reclaiming used syringe to prevent nosocomial infection, use for secondary, cause very big harm to people.The present disposable syringe syringe needle device that unmakes is made up of metallic element mostly, because this device precise structure complexity of unmaking, and the syringe needle after using is stained with liquid glucose more, often causes the corrosion of metallic element, has a strong impact on the service life of the device that unmakes; And the price of having unmake is higher, and the self-disinfection difficulty is so be difficult to apply in hospital.The medical personnel that also have are unmake to syringe needle is manual with instruments such as shears, pliers, but syringe needle is easy to stab hand skin, and medical personnel's health is caused very major injury.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, safe and convenient to use, and syringe needle unmakes and is easy to the disposable syringe syringe needle device that unmakes.

The purpose of this utility model is achieved in that this disposable syringe syringe needle device that unmakes is made up of casing, drawing box, cutting knife, pressing plate, casing one end is uncovered, inside is with the drawing box that adapts with cabinets cavity, being provided with the cross section that communicates with cabinets cavity in the middle of the casing upper face is rectangular sleeve pipe, the sleeve pipe upper surface has through hole, post upper is connected with pressing plate, the limiting plate that has cutting knife above the lower end is passed in through hole and the sleeve pipe on the sleeve pipe upper surface links to each other, and is with support spring on the support bar between pressing plate and the sleeve pipe upper surface; Be connected with the square beam that has grooving above adapting with cutting knife between the tube wall of the inside pipe casing left and right sides, have on the tube wall of sleeve pipe back and the corresponding needle insertion hole of square beam, the syringe needle that has the inverted triangle shape in the needle insertion hole bottom breaks away from bayonet socket.

During use, left hand is held syringe, syringe needle is inserted from needle insertion hole and is placed on the crossbeam that has grooving, and the right hand is pushed pressing plate, and cutting knife can cut off syringe needle, the syringe needle that cuts off is fallen in the drawing box that fills disinfectant solution, the syringe that just has the half syringe needle then inserts syringe needle and breaks away from the bayonet socket, moves down, and makes the disengaging bayonet socket block the syringe needle root, the pulling syringe, syringe needle can be shed in the drawing box.

Advantage of the present utility model: simple in structure, safe and convenient to use, be easy to cleaning and sterilizing, long service life when medical personnel carry out craft and unmake syringe needle, can not stabbed hand skin, stops disposable aspiration needle and recycles.
