Abstract
The utility model discloses a disposable directly syringing ampoule, belonging to a medical syringe. The disposable directly syringing ampoule is composed of an ampoule part and a pushing part. The main body of the ampoule part is a hollow cylinder body filled with injection. A pushing piston is arranged inside the tail end of the hollow cylinder body, and the front end of the hollow cylinder body is provided with an injecting papilla. A needle storing chamber of the cylindrical pushing part is provided with an injecting needle head. The front end of the pushing part is a pushing post. The injecting papilla is inserted to the injecting needle head to pull out the pushing post. After the cooperation of the outer screw thread of the pushing post and the inner screw thread of the pushing piston, the injection is oppressed by the pushing piston into human body through the injecting needle head. The utility model is provided with injection packaging function and the function of syringes. The utility model is convenient to be transported and carried, reduces the medical persons' operating processes and avoid the injection being polluted.
Description
This utility model belongs to a kind of injector for medical purpose.
Existing ampoule is a kind of seal glass small jar of adorning injection.During use, the bottleneck upper end must be staved, injection is drawn in the syringe by syringe needle, by propeller injection is injected in the patient body by syringe needle more then with syringe.In recent years, though the syringe made with non-toxic plastic occurred, ampoule remains and adopts glass to make.Like this, when medical personnel give patient injection with syringe, not only will be with whole syringe thorough disinfection, and ampoule bottleneck end must be staved, so operation sequence bothers, medical personnel's labor intensity is big, particularly glass ampule damages easily.
The purpose of this utility model is a kind of therapeutic medical, device with packing injection and function of injection of design, and replacing present injector for medical purpose, thereby the simplification injecting program alleviates medical personnel's labor intensity.
For this reason, this utility model is taked following technical scheme:
It is made up of ampoule portion and promotion part.Ampoule portion main body is that hollow a, sectional area is circular cylindrical shell, it is the ampoule cylindrical shell, its hollow interior is used for the splendid attire injection, one propelling piston is housed in barrel tip, it and cylinder inboard wall be sealed sliding movingly, terminal outer a seal cover is housed also at this, an approximate ellipsoidal pull handle is arranged outside being positioned at seal cover the place ahead, cylindrical shell.There is the cylindrical boss of a hollow at ampoule barrel front end end face middle part, and this boss is consolidated with the tubular injection nipple of a hollow little than its diameter, injects nipple and is with a sealing cap outward; One conical storage pin chamber is arranged in the tubular promotion part.The entry needle that can take out is housed, at the outstanding cylindrical propelling post of promotion part front end in it.
Entry needle in the promotion part comprises syringe needle and needle holder, and syringe needle is fixed on the needle holder.One cylindrical space is arranged in the needle holder, can insert in it for above-mentioned injection nipple.In addition, the propelling post surface of promotion part front end has an external screw thread, and after seal cover was taken off from the ampoule barrel tip, above-mentioned propelling post can match with female thread in the propelling piston space in it.
When this utility model is used for clinical injection, to inject Supramammillary sealing cap earlier takes off, to inject nipple then and insert in the space of needle holder in the end of promotion part,, just entry needle can be taken out from the taper shape storage pin chamber of promotion part by the frictional resistance that is produced because of extruding between them.At this moment, seal cover with ampoule portion end takes off again, and the propelling post external screw thread of promotion part front end is matched with female thread in its interior propelling piston space, then syringe needle is penetrated in the human body skin, reuse forefinger, middle finger block pull handle, slowly affact the promotion part end with thumb.Propelling piston in the ampoule barrel tip is slowly advanced along cylinder inboard wall, and injection slowly is expelled in the human body by syringe needle in it thereby make.
This utility model can be packed injection, is again syringe, is convenient to transportation and carries, and reduces medical worker's operation sequence, reduces labor intensity, and has stopped traditional type simultaneously and has inhaled the pollution to medicinal liquid that may cause in the medicine process.Because be disposable use, also can prevent the mutual infection of sick body again.Because main body is that plastics are made, so cost reduces greatly.
