Description

Special needle of vaccination subcutaneous intramuscular injection

Technical Field

The utility model relates to the technical field of hypodermic injection and intramuscular injection, in particular to a special needle for vaccination subcutaneous intramuscular injection.

Background

The children vaccination in China is comprehensively popularized, and the daily vaccination is very high in addition to the popularization of the new crown vaccine in recent years, the current domestic vaccination modes are mainly three modes of oral administration, subcutaneous injection and intramuscular injection, the specification of an injector generally used for the subcutaneous injection and the intramuscular injection is 1 ml, and the depth of inserting a needle head into a human body is 1\2-2\3 of the needle stalk, because the depth is not easy to control, the specification of the injector is small, some children are afraid of not matching when inoculating the needle, most of medical staff pricks all the needle heads into the vaccination part when performing the vaccination, the vaccination mode is inaccurate, the effect or absorption of the medicine is influenced, for example, the subcutaneous injection is performed on the premise of holding the correct needle inserting angle, and the subcutaneous tissue is just reached if the needle inserting depth is 1\2-2\3 of the needle head, if the needle head is completely inserted, the needle head can possibly enter the muscle tissue;

sometimes, an inoculator is not matched, or medical staff often pulls out the needle or advances deeply again when blood is pumped back and medicine is pushed, so that liquid medicine is seeped back, and scars, edema, induration and the like appear at an injection part;

the needle breakage may occur during subcutaneous injection or intramuscular injection, and most of the needle breakage is caused by the fact that the needle stalk is completely punctured into the skin, the needle is not easy to take out by hands or tweezers after the needle breakage, the skin needs to be cut by a scalpel to take out, and the pain is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a safe, accurate and efficient injection device, which can ensure the injection depth, avoid more accidents during injection and solve the problems in the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a special needle of vaccination subcutaneous intramuscular injection, includes syringe body (1), syringe needle body (2), needle cover (4), shock insulator (3), its characterized in that: one end of the needle head body (2) with the needle head is provided with a spacer (3) and is packaged through a needle sleeve (4), and the other end of the needle head body is movably arranged on the injector body (1);

the spacer (3) is made of PTFE material and is fixedly arranged at the position 2\3 away from the outer surface of the needle stem of the needle head body (2).

The spacer (3) can be in the shape of a water drop, a square, a circle or an ellipse, the width of the spacer is less than or equal to the inner diameter of the needle sleeve (4), and the length of the spacer is less than the needle stalk which is 1/3 of the length away from the needle head body.

The outer surface of the needle sleeve (4) is provided with friction patterns which can be a frosted surface, a striped surface or a groove surface.

Compared with the prior art, the utility model only adds a water drop-shaped PTFE material pad at 2/3 of the outer surface of the needle stalk of the injector, prevents the needle head from being injected completely, has simple manufacture and low cost, can ensure the insertion depth of the needle stalk, effectively avoids the over-deep or over-shallow insertion during the vaccination, and provides reliable guarantee for the right way of vaccinating people.

The utility model can accurately control the injection depth of the needle stem and avoid incorrect injection mode; the needle is easy to fix when in injection, and the needle cannot be pulled out or deepened again; after the broken needle is broken, the spacer can be pinched to easily pull out the broken needle; when in medicine adding, the needle can be accurately inserted into the ampoule bottle or the self-sealing bottle due to the relatively large reference object; has the advantages of low manufacturing cost, convenient and safe use and the like.
