Abstract
The utility model provides a needleless drug feeding component, comprising a body and a rubber plug, wherein the body is provided with a body internal tube; one end of the body internal tube is used for communication with a transfusion tube of a transfusion device; the other end of the body internal tube is provided with a needle body; a needle body internal tube is arranged in the needle body; the needle body internal tube is communicated with the body internal tube; one end of the rubber plug is sealed; the other end of the rubber plug is provided with an opening; the rubber plug is sheathed on the needle body. According to the needleless drug feeding component, the rubber plug of which one end is of a seal structure is sheathed on the needle body, so that the pipeline of the body is sealed; in such a way, even when being under greater pressure, no liquid drug in the pipeline of the transfusion device flows outward from the drug feeding component; therefore, the needleless drug feeding component has a more stable sealing effect.
Description
Technical field
This utility model relates to a kind of Needleless dosing part, belongs to field of medical article technology.
Background technology
In clinical transfusion, there will be the situation of medicine in liquid-transport pipe-line of repeatedly temporarily annotating in the transfusion of prolonged and repeated transfusion or single, therefore on the tube for transfusion 2 of infusion set, meeting is other connects dosing part 1, shown in accompanying drawing 1.Existing dosing part structure comprises a pipeline, and this pipeline is communicated with the tube for transfusion of described infusion set, establishes a plug in described pipeline, this plug is provided with designated port, when not from the dosing of dosing part, relies on the elasticity of plug material itself, designated port is closed, thereby the liquid of tube for transfusion is not outflowed.When from the dosing of dosing part, syringe needle (for example syringe needle of syringe) is through designated port, and additional medicinal liquid flows from dosing part to tube for transfusion, needs syringe needle during due to dosing, is therefore generally called and has pin dosing part.The shortcoming of this technology is: utilize enclosed elastic dosing part of plug material itself to make sealing effect unstable, and the pressure of the medicinal liquid in tube for transfusion is when larger, the medicinal liquid of tube for transfusion easily flows out from the designated port of plug.
Summary of the invention
This utility model provides a kind of Needleless dosing part.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Needleless dosing part, comprise body and plug, and this body is provided with body inner tube; One end of described body inner tube is in order to be communicated with the tube for transfusion of infusion set, and the other end is provided with a needle body, is provided with needle body inner tube in this needle body, and this needle body inner tube is communicated with described body inner tube; The sealing of described plug one end, an end opening; Described plug is set on described needle body.
Preferred technical scheme is: described body and described needle body are integrally formed.
Preferred technical scheme is: also comprise a protective sleeve, described protective sleeve is set in outside described plug and is tightly connected with described body, and described protective sleeve is provided with medicine feeding hole.
Preferred technical scheme is: described protective sleeve and described body are integrally formed.
Preferred technical scheme is: described syringe needle is draw point, and this draw point and described body are pegged graft and be shaped.
Because technique scheme is used, this utility model compared with prior art has following advantages:
This utility model adopts the plug that one end is hermetically-sealed construction to be set on needle body, thereby seals the pipeline of body, even if make medicinal liquid in the pipeline of infusion set under larger pressure, can not outflow from dosing part.Therefore sealing effectiveness of the present invention is more stable.

The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further described:
Notice, appended graphic the illustrated structure of this description, ratio, size etc., equal contents in order to coordinate description to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the present invention, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under the effect that the present invention can produce and the object that can reach, all should still drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the present invention.
Embodiment: a kind of Needleless dosing part
A Needleless dosing part, comprises body 5 and plug 3, and this body 5 is provided with body inner tube 7; One end of described body inner tube 7 is communicated with in order to the tube for transfusion 2 with infusion set, the other end is provided with a needle body 6, in this needle body 6, is provided with needle body inner tube 8, and this needle body inner tube 8 is communicated with described body inner tube 7, medicinal liquid just can think that body inner tube 7 flows from needle body inner tube 8 like this, until flow in tube for transfusion 2.The sealing of described plug one end, an end opening; Described plug is set on described needle body 6, and plug 3 can be the soft rubber stopper that medical grade rubber is made, and aims at needle body 6 one end be set on needle body 6 with that one end of opening, can be tightly connected with needle body 6, for example, with glue, plug 3 is fixed on needle body 6.Needle body 6 can be plastic spike or the metal needle that common injector for medical purpose is used, and its structure is prior art, and one end of needle body 6 is pin hole tip, porose on it.
Described body 5 can be one of the forming with the assembling mode of described needle body 6.Also can be entry needle to be inserted to body 5 form, but must guarantee that body inner tube 7 and needle body inner tube 8 are communicated with.
Because plug 3 is that rubber is made, so it is softer, therefore need to be at the outer sheathed protective sleeve 4 of plug 3, and described protective sleeve 4 is tightly connected with described body 5, and described protective sleeve is provided with medicine feeding hole.
