Abstract
The utility model relates to an infusion apparatus stopper puncture outfit. A steel needle sleeve is arranged on a puncture outfit base; both sides of the front end of the steel needle sleeve are respectively provided with an air inlet hole and a liquid inlet hole, the elliptic edges of which are sunken; an air inlet tube and an air inlet end connected with the air inlet tube are arranged in the steel needle sleeve and on the puncture outfit base; the puncture outfit base also comprises a liquid inlet end; a liquid inlet tube which is arranged on the puncture outfit base and in the steel needle sleeve is connected with the liquid inlet end; and the upper ends of the air inlet tube and the liquid inlet tube respectively correspond to the air inlet hole and the liquid inlet hole. The utility model has the following advantages: firstly, the structure is simple, the fabrication technique is simple, the puncturing resistance is low, no cutting force is applied on a rubber stopper, rubber particles are prevented from coming off to cause pollution, the needle hole cannot be easily blocked, use is convenient, and the performance is reliable; secondly, the glue used for bonding is effectively prevented from being contacted with liquid during infusion in a patient.
Description
Technical field
This utility model relates to a kind of transfusion device bottle plug puncture unit, relates in particular to the structure of feed tube, draw point cover and perforator seat in this transfusion device bottle plug puncture unit.
Background technology
Infusion techn is in a kind of method of clinical treatment widespread usage, especially improves now at medical level, and the safety of disposable infusion product and human oriented design more are subjected to paying close attention to widely.
Generally adopting the transfusion device sting device in the past is two each self-separation stainless steel tubes, is respectively an air inlet, a feed liquor, adopts earlier during use and inserts the feed liquor pin, injects air tube again, the very trouble that operates, and easily produce the plug exfoliation and produce pipeline blockage.
Recent most of manufacturer adopts the Plastic bottle plug perforator of injection moulding disposal molding that the two function of front and structure are united two into one, feed liquor and air inlet are in structure, though do not need to repeat to insert bottle, but because diameter is thicker, need exert oneself to puncture, perforator sharp-pointed portion rust easily takes place during puncture or fracture, infusion process is produced certain influence, cutting force to bottle closure of rubber is also big, is easy to generate rubber grain and comes off and the needle point obstruction, uses inconvenience.
Summary of the invention
This utility model technical issues that need to address have provided a kind of transfusion device bottle plug puncture unit, are intended to solve the above problems.
In order to solve the problems of the technologies described above, this utility model is achieved through the following technical solutions:
This utility model comprises: a draw point cover that is placed on the perforator seat; Draw point cover front end both sides have air inlet and the inlet opening that elliptical edge caves in; In draw point cover, the inlet end that air inlet pipe arranged and link to each other on the perforator seat with air inlet pipe; The perforator seat also comprises: a liquid feeding end; A feed tube that is placed on the perforator seat, in the draw point cover links to each other with liquid feeding end; The upper end of described air inlet pipe and feed tube is corresponding respectively with air inlet and inlet opening.
Compared with prior art, the beneficial effects of the utility model are: the first, and simple in structure, processing technology is easy, and it is little to insert the bottle resistance, and bottle closure of rubber is not had cutting force, has avoided rubber grain pollutions that come off, and pin hole is difficult for obstruction, and is easy to use, dependable performance; The second, the glue of effectively having avoided using in the bonding process contacts with the liquid of patient when infusing.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:
As seen from Figure 1: this utility model comprises: a draw point cover 1 that is placed on the perforator seat 2; Draw point overlaps 1 front end both sides and has air inlet 11 and the inlet opening 12 that elliptical edge caves in; In draw point cover 1, the inlet end 23 that air inlet pipe 21 arranged on the perforator seat 2 and link to each other with air inlet pipe 21; Perforator seat 2 also comprises: a liquid feeding end 24; A feed tube 22 that is placed on the perforator seat 2, in draw point cover 1 links to each other with liquid feeding end 24; The upper end of described air inlet pipe 21 and feed tube 22 is corresponding respectively with air inlet 11 and inlet opening 12;
Described air inlet 11 is higher than inlet opening 12;
Described draw point cover 1 is placed on the perforator seat 2 and is: the gum box 25 that draw point cover 1 inserts on the perforator seat 2.
This utility model adopt air inlet feed liquor integral type plastic construction to be placed on the perforator seat and one forwardly both sides have the cave in draw point cover of edge hole of ellipse and form.Draw point cover lower end is positioned at the draw point gum box of perforator seat, and the position cooperates closely.
Perforator seat in this utility model adopts the Environmental Safety designing technique, the perforator seat is provided with draw point cover gum box, owing to extend into the distance of trachea and feed tube liquid phase pair and draw point gum box, the medicinal liquid of patient's transfusion and contacting of binding part glue can have effectively been avoided after the overall package bonding, meet the basic demand of country to the medical device product supervision, guaranteeing under the prerequisite that product quality and performances meet clinical needs, by structure Design having been realized in process of production to binding agent, the technology controlling and process of solvent, thereby improved environmental protection, safety and effective has guaranteed that the public uses tool safety.
