Abstract
The utility model relates to medical instruments and discloses a pressure injection instrument, which comprises an injection needle and a needle cylinder, wherein the injection needle comprises a needle head and a needle head holder for fixing the needle head; the needle cylinder comprises an anti-drop needle cylinder connector, an injection barrel body and an injection push handle, wherein the injection barrel body and the injection push handle are sleeved with each other in a sliding manner; and one end of the anti-drop needle cylinder connector is in threaded connection with the needle head holder of the injection needle, while the other end is fixedly connected with the injection barrel body. The pressure injection surgical instrument of the utility model is obviously improved in safety for preventing the injection needle cylinder from dropping due to pressure, in uniformity of medicine injection force and in therapeutic effect and injection safety, avoids medicine loss caused by the falling operation of the injection needle cylinder, raises the working efficiency of injector remarkably, enhances the utilization rate of injected medicines, simultaneously reduces the risk that the moment the injection needle is separated from the needle cylinder, the injection needle slides to wrongly puncture into normal tissues, and provides essential condition for pressure injection treatment of patients.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of pressure injection apparatus.
Background technology
Injecting apparatus, be a kind of clinical in therapeutic device commonly used, be applicable to that injection of drug, local anesthesia administration, diseased region directly inject treatment etc.But at integumentary musculature during the injection of the higher position of more plentiful and pressure; Usually because injection tube internal feedback hypertonia; Cause entry needle and syringe to come off, medicine leaks in addition because entry needle and syringe come off moment slide to miss and thrust normal structure, cause damage, consequence is serious.
Injecting apparatus comes off because of pressure causes entry needle and syringe, usually occurs in entry needle and syringe connecting portion, because of connecting portion is the shiny surface contact, can not bear the syringe internal pressure.So when pressure was injected than large part, it was usually excessive because of pressure to execute the patient, cause that entry needle and syringe come off, medicinal liquid leaks, medicinal liquid all can cause damage to executing patient and patient.Simultaneously because worrying pressure injection pin and syringe comes off, execute the patient and dare not excessively exert pressure and inject medicine, finally cause medicine and can not inject therapentic part, influence is treated.Develop a kind of pressure position injection for curing apparatus for this reason and become the clinical problem of being badly in need of solution.
At present domesticly still adopt conventional entry needle to be connected with syringe; Be that connecting portion is shiny surface contact, in order to prevent that entry needle and syringe from coming off, execute the patient and dare not excessively exert pressure and inject medicine during the operation of pressure position; Medicine can not inject therapentic part, does not reach the treatment requirement.If excessive because of pressure, cause that entry needle and syringe come off, medicinal liquid leaks, medicinal liquid all can cause damage to executing patient and patient, and consequence is serious.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, and a kind of new pressure injection apparatus is provided.
This utility model has adopted following technical proposals:
A kind of pressure injection apparatus; Comprise entry needle and syringe, said entry needle comprises syringe needle and the needle holder that is used for fixing syringe needle, and said syringe comprises that anticreep syringe union joint, injection ladle body and injection push away handle; Wherein, Injection ladle body and injection push away handle slip socket, and said anticreep syringe connects first end and is threaded with the needle holder of entry needle, and the other end is fixedly connected with the injection ladle body.
Further, said anticreep syringe union joint is provided with external screw thread, and the needle holder of said entry needle is provided with female thread.
Further, said injection ladle body is provided with anti-skidding stricture of vagina.
The capacity of this utility model pressure injection apparatus is general capacity.
This utility model has taken into full account the technical essential of pressure injection in design; Adopt entry needle to embed through screw thread rotation with anticreep syringe union joint and be connected, the even dynamics that medicine injects when having guaranteed pressure injection has had obvious improvement on the uniformity of safety and dynamics during to pressure injection; Therapeutic effect is significantly increased; And if avoided because of excessive because of pressure, causing that entry needle and syringe come off, medicinal liquid leaks, medicinal liquid all can cause damage to executing patient and patient; Prevented that also the come off moment mistake of sliding of entry needle and syringe from thrusting normal structure; For patient's art treatment provides good guarantee, and this utility model coupling syringe capacity is general capacity, is easy to popularize.

The specific embodiment
Pressure injection apparatus as shown in Figure 1; Comprise entry needle and syringe; Said entry needle comprises syringe needle 1 and the needle holder 2 that is used for fixing syringe needle, and said syringe comprises that anticreep syringe union joint 3, injection ladle body 4 and injection push away handle 5, and injection ladle body 4 pushes away handle 5 slip sockets with injection; Said anticreep syringe union joint 3 one ends are threaded with the needle holder 2 of entry needle, and the other end is fixedly connected with injection ladle body 4.
Further, said anticreep syringe union joint 3 is provided with external screw thread, and the needle holder 2 of said entry needle is provided with female thread.
Further, said injection ladle body 4 is provided with anti-skidding stricture of vagina.
Claims (3)
1. a pressure injection apparatus comprises entry needle and syringe, and said entry needle comprises syringe needle and the needle holder that is used for fixing syringe needle; Said syringe comprises that anticreep syringe union joint, injection ladle body and injection push away handle; Wherein, injection ladle body and injection push away handle slip socket, it is characterized in that; Said anticreep syringe connects first end and is threaded with the needle holder of entry needle, and the other end is fixedly connected with the injection ladle body.
2. pressure injection apparatus according to claim 1 is characterized in that said anticreep syringe union joint is provided with external screw thread, and the needle holder of said entry needle is provided with female thread.
