Abstract
The invention discloses a needleless medicine adding part which comprises a body and a rubber plug. A body inner tube is arranged on the body, one end of the body inner tube is used for being communicated with an infusion tube of an infusion device, a needle body is arranged at the other end of the body inner tube, a needle body inner tube is arranged in the needle body, and the needle body inner tube is communicated with the body inner tube. One end of the rubber plug is sealed, the other end of the rubber plug is opened, and the needle body is sleeved with the rubber plug. According to the needleless medicine adding part, one end of the rubber plug is of a sealing structure, the needle body is sleeved with the rubber plug, therefore, a pipe of the body is sealed, and liquid medicine in a pipe of the infusion device cannot flow out of the medicine adding part even under large pressure. Therefore, the needleless medicine adding part is stable in sealing effect.
Description
Technical field
The present invention relates to a kind of Needleless dosing part, belong to field of medical article technology.
Background technology
In clinical transfusion, there will be in prolonged and repeated transfusion or single transfusion the situation of medicine in liquid-transport pipe-line of repeatedly temporarily annotating, 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, the designated port closure, thus make the liquid of tube for transfusion not outflow.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 the dosing part to tube for transfusion, needs syringe needle during due to dosing, therefore generally is called pin dosing part is arranged.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
The object of the invention is to provide a kind of Needleless dosing part.
For achieving the above object, the technical solution used in the present invention is: a kind of Needleless dosing part, comprise body and plug, and this body is provided with the 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 the needle body inner tube in this needle body, and this needle body inner tube is communicated with described body inner tube; Described plug one end sealing, 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, the present invention compared with prior art has following advantages and effect:
The present invention adopts the plug that an end is hermetically-sealed construction to be set on needle body, thereby seals the pipeline of body, even make medicinal liquid in the pipeline of infusion set under larger pressure, can not outflow from the dosing part.Therefore sealing effectiveness of the present invention is more stable.

Notice, appended graphic the illustrated structure of this description, ratio, size etc., equal contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, 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 purpose 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 ", D score, " left side ", " right side ", " centre " reach the term of " " 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 also being considered as the enforceable category of the present invention.
Embodiment: a kind of Needleless dosing part
A kind of Needleless dosing part, comprise 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.Described plug one end sealing, 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 ends with that end of opening and is set on needle body 6, 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 an end of needle body 6 is the pin hole tip, porose on it.
Described body 5 can be one of the forming with the assembling mode of described needle body 6.Can be also 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.
Described protective sleeve and described body are integrally formed.Also can adopt and be threaded or mode that buckle connects.
In use, can use the syringe of needleless, with the sealed end of the head conflict plug 3 of syringe, when applying certain pressure, plug 3 can generation be dodged action and move down, and needle body 6 punctures plug 3, thereby make the medicinal liquid in syringe enter in needle body 6, flow to tube for transfusion 2.When protective sleeve is arranged, the head of the syringe of needleless enters in protective sleeve from medicine feeding hole, and makes head conflict plug 3.In another embodiment, described syringe needle is draw point, and this draw point and described body are pegged graft and be shaped.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that spirit is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
