Abstract

The utility model relates to an intramuscular syringe needle with a single cavity and two holes. A small round hole is arranged on the back side of the inclined hole of an existing general intramuscular needle for human bodies at the point which is 4 mm from a needle tip, and the diameter of the small round hole is 0.5 mm. Spraying and bidirectional shunt functions are formed on partial tissue when physic liquor is injected into muscle, so that the concentration of drug in the partial tissue is reduced, irritation is reduced, and the physic liquor is convenient to absorb. Pain during muscle injection is alleviated, and scleroma is not easily formed after the muscle injection. The utility model has the advantages of simple operation, labor saving and time saving.

Description

Single chamber diplopore intramuscular injection syringe needle

This utility model relates to a kind of technological improvement of medical needle, specifically is a kind of single chamber diplopore intramuscular injection syringe needle.

At present, the injection needle of medical various models, because tip portion all has the limitation of a pin hole, when causing intramuscular injection, medicinal liquid can only spread to in-vivo tissue to direction of veutro of needle point by the pin chamber., medicinal liquid is assembled in local organization, concentration is too high relatively, zest is stronger, the pain when easily causing intramuscular injection＜especially the inject stronger medicine of zest 〉, and absorb slowlyer, intramuscular injection is local hardens easily.

The purpose of this utility model at the deficiencies in the prior art part, provides a kind of pain can alleviate intramuscular injection the time, can prevent single chamber diplopore intramuscular injection syringe needle of intramuscular injection scleroma again.

To achieve these goals, the technical scheme that this utility model solves is at existing human body intramuscular injetion needle inclined hole dorsal part commonly used, apart from needle point 4mm place, and the spray hole that to be provided with a diameter be 0.5mm＜do not connect 〉.

Adopt the syringe needle of this structure, utilize the principle of pressurization spray and bidirectional shunt, make the medicine of intramuscular injection can be simultaneously to two different direction hydrojets and diffusion is rapidly quickened to absorb, reduce medicine and the stimulation of local organization reached the purpose of hardening after pain when alleviating intramuscular injection and the intramuscular injection.

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with accompanying drawing this utility model embodiment is described in detail.

By shown in Figure 1, in existing human body intramuscular injetion needle commonly used＜1〉inclined hole＜2 dorsal part, apart from needle point 4mm place, hydrojet small sircle hole＜3 that to be provided with a diameter be 0.5mm 〉.During intramuscular injection, medicine can be simultaneously to the portalling hydrojet of both direction and diffusion is rapidly quickened to absorb, reduce the stimulation of medicine, thereby reach pain when alleviating intramuscular injection and the scleroma after the intramuscular injection local organization.

Advantage of the present utility model, the one, rational in infrastructure, to make easily, cost is low; The 2nd, pain is light or do not have pain during intramuscular injection; The 3rd, medicine is inhaled after the intramuscular injection Receive comparatively fast, and be difficult for forming scleroma; The 4th, easy and simple to handle, laborsaving saving time can be big Extenuate greatly user's labour intensity.

Claims

1, this utility model relates to a kind of single chamber diplopore intramuscular injection syringe needle, it is characterized in that: in existing human body intramuscular injetion needle commonly used＜1〉inclined hole＜2 dorsal part, apart from needle point 4mm place, small sircle hole＜3 that to be provided with a diameter be 0.5mm 〉.
