The utility model discloses a design into the structure that is less than the edge on the cavity opening of lag with the connecting sleeve up end, when the needle tubing pours into human skin tissue into, the protective sleeve up end can paste flat skin tissue, forms a plane protection to can prevent effectively that the closed angle of connecting sleeve upper end from pricking into in the skin tissue and the secondary damage that causes.
Description
Technical Field
The utility model belongs to the technical field of medical instrument technique and specifically relates to an insulin syringe needle.
Background
Exogenous insulin is mainly used for treating diabetes, and liquid medicine is injected into human tissues in an injection mode to achieve the purpose of reducing and regulating blood sugar.
The connecting sleeve end part between the injection needle tube and the needle body of the existing needle head structure for insulin injection is in a pointed cone shape, when the injection needle tube is pricked into the skin tissue of a human body, the sharp corner at the end part of the connecting sleeve is easy to prick into the tissue of the human body to stab the skin of the human body, which is equivalent to two injuries to the wound of the human body.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides an insulin injection needle which can effectively prevent the skin of a human body from being injured twice when in use.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an insulin syringe needle, has needle body, needle tubing and adapter sleeve, the integrative setting of adapter sleeve in the needle body upper end, the lower extreme runs through the adapter sleeve on the needle tubing, needle body up end be equipped with the lag, the lag has upper end open-ended cavity, the link sleeve up end is less than the opening up edge face of cavity.
Preferably, the upper end face of the connecting sleeve is 0.5-1.5 mm lower than the upper edge face of the opening of the concave cavity.
In order to facilitate the molding and manufacturing, the protective sleeve, the needle body and the connecting sleeve are of an integral structure formed by injection molding.
Furthermore, the outer diameter of the protecting sleeve is the same as that of the needle body.
Furthermore, the opening of the concave cavity is provided with a chamfer angle of 0.5-1.5 mm.
The beneficial effects of the utility model are that: the utility model discloses a design into the structure that is less than the edge on the cavity opening of lag with the connecting sleeve up end, when the needle tubing pours into human skin tissue into, the protective sleeve up end can paste flat skin tissue, forms a plane protection to can prevent effectively that the closed angle of connecting sleeve upper end from pricking into in the skin tissue and the secondary damage that causes.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the needle body, 2 needle tubes, 3 connecting sleeves, 4 protecting sleeves, 5 cavities and 6 skin tissues.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The insulin injection needle shown in fig. 1 comprises a needle body 1, a needle tube 2 and a connecting sleeve 3, wherein the connecting sleeve 3 is arranged on the upper end surface of the needle body 1, and the upper end and the lower end of the needle tube 2 penetrate through the connecting sleeve 3.
The utility model discloses a needle body, including the needle body 1, the lag 4, the body structure of lag 4, needle body 1, adapter sleeve 3 for injection moulding, the lag 4 the same with needle body 1 external diameter.
The protecting sleeve 4 is provided with a concave cavity 5 with an opening at the upper end, the opening of the concave cavity 5 is provided with a chamfer angle of 1mm, and the upper end face of the connecting sleeve 3 protruding out of the needle body 1 is positioned in the concave cavity and is 1mm lower than the upper edge face of the opening of the concave cavity 5.
According to the injection needle with the structure, the upper end face of the connecting sleeve 3 is lower than the opening upper edge face of the cavity 5 of the protecting sleeve 4, when the needle tube is injected into the skin tissue 6 of a human body, the upper end face of the protecting sleeve 4 can be flatly attached to the skin tissue 6 to form a plane protection, and therefore secondary damage caused by the fact that the sharp corner at the upper end of the connecting sleeve 3 is pricked into the skin tissue 6 can be effectively prevented.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
