CN203029734U - Limiting injector - Google Patents

Abstract

The utility model discloses a limiting injector which comprises an injector body and a needle head. The injector body is provided with a piston. The needle head is provided with a needle head seat. A needle head is connected at the top end of the injector body through the needle head seat in a sleeved mode. The limiting injector is characterized in that a limiting device is arranged outside the needle head, the limiting device is a rubber ring or a plastic ring, the outer diameter of the rubber ring or the plastic ring is tangential with the outer diameter of the needle head, and the limiting device is movably arranged outside the needle head. Compared with the prior art, due to the fact that the limiting device is arranged outside the needle head, a user can conveniently master an injection depth of the needle head, and the limiting injector is safe and practical.

Description

Spacing syringe

Technical field

This utility model relates to a kind of being convenient to the spacing syringe of control injection depth.

Background technology

Conventional injector comprises the syringe body that has piston and the syringe needle that has needle holder, syringe needle is socketed in the top of syringe body by needle holder, doctor or nurse determine the degree of depth of injecting by rule of thumb, but there is nurse's working experience of a lot of youths also to be short of, be difficult to the degree of depth of control injection, particularly the child is when carrying out the buttocks intramuscular injection, it is dark excessively that medicated pillow is pricked, bundle arrives the shank nerve easily, cause deformity, also some patient needs injection voluntarily, but they did not accept regular training, so the degree of depth of injection is difficult to control concerning them.

The utility model content

The problems referred to above that this utility model need solve are at above-mentioned the deficiencies in the prior art, are convenient to the spacing syringe of control injection depth and provide a kind of.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of spacing syringe comprises the syringe body that has piston and the syringe needle that has needle holder, and syringe needle is socketed in the top of syringe body by needle holder, it is characterized in that: in the syringe needle outer setting one stopping means is arranged.

Described stopping means is rubber ring or the plastic ring tangent with the syringe needle external diameter.

Described stopping means is movably arranged on the syringe needle outside.

Compared with prior art, spacing syringe of the present utility model has a stopping means in the syringe needle outer setting, is convenient to user the injection depth of control syringe needle, and is safe and practical.

Description of drawings

Fig. 1 is the structural representation of utility model;

Wherein, 1, syringe body, 2, syringe needle, 3, stopping means.

The specific embodiment

Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of spacing syringe comprises the syringe body 1 that has piston and has the syringe needle 2 of needle holder, and syringe needle 2 is socketed in the top of syringe body 1 by needle holder, in syringe needle 2 outer setting one stopping means 3 is arranged.

Stopping means 3 is rubber ring or the plastic ring tangent with syringe needle 1 external diameter.

Stopping means 3 is movably arranged on syringe needle 2 outsides.

Spacing syringe of the present utility model can be accurately the control injection depth at the stopping means 3 of syringe needle 2 outer setting, no matter be doctor, nurse or patient all the same safe readies that operates; Stopping means 3 can also be according to its fixed position on syringe needle 2 of fat or thin regulated at will of people, and convenience is easy to operate.

Claims (3)
