Abstract
This utility model relates to a kind of novel transfusion bag dosing mouth composite cover, it comprises transfusion bag (1), tube for transfusion (2) and air deflector (3), transfusion bag (1) top is provided with tube for transfusion (2), the lower end of tube for transfusion (2) is provided with connection tube (4), connection tube (4) lower end is plugged in transfusion bag (1), the upper end of tube for transfusion (2) is provided with air deflector (3), air deflector (3) comprises sheath body (7), check valve diaphragm (8) and inner cap (5), sheath body (7) is fixedly installed on the upper surface of tube for transfusion (2), inner cap (5) is set in the inner side of sheath body (7), check valve diaphragm (8) is arranged between sheath body (7) and inner cap (5).This utility model, by adopting air deflector, makes transfusion conveniently to enter in transfusion bag, and transfusion can be avoided to flow backwards transfusion bag, causes transfusion and extraneous contact to pollute and infuses, ensure that the safety and hygiene of transfusion.
Description
Technical field
This utility model relates to medical infusion bags, particularly a kind of novel transfusion bag dosing mouth composite cover.
Background technology
At present, the transfusion device that domestic market uses is most for only can carry out unidirectional transfusion, and when infusing inadequate, then directly change transfusion bag, the use amount causing transfusion bag is very large.Not only increase the cost of medical infusion to a certain extent, increase pollution risk simultaneously.Therefore, realize toward transfusion bag in, carry out increase medicinal liquid and become widespread demand in market.
And conventional combination lid product of the prior art, comprise enclosing cover, rubber cushion and inner cap.Rubber cushion is arranged between enclosing cover and inner cap.When assembling, rubber cushion is placed on the inside of enclosing cover, then puts into inner cap, inner cap is fixed together by the buckle structure between inner cap external annulus and enclosing cover internal ring wall and outer cover latch, thus is fixed in enclosing cover by rubber cushion buckle.And the composite cover of this structure is higher to requirement on machining accuracy on the one hand, guarantee that medicinal liquid is not high with the difficulty of extraneous contact in use procedure, substantially cannot realize the function increasing medicinal liquid on the other hand, more cannot ensure to increase in medicinal liquid process, medicinal liquid does not reflux out.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of structure is simple, dosing and the novel easily transfusion bag dosing mouth composite cover of transfusion.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel transfusion bag dosing mouth composite cover, it comprises transfusion bag, tube for transfusion and air deflector, tube for transfusion is provided with above described transfusion bag, the lower end of described tube for transfusion is provided with connection tube, connection tube lower end is plugged in transfusion bag, connection tube is connected with transfusion bag inside, the upper end of described tube for transfusion is provided with air deflector, described air deflector comprises sheath body, check valve diaphragm and inner cap, sheath body is fixedly installed on the upper surface of tube for transfusion, inner cap is set in the inner side of sheath body, check valve diaphragm is arranged between sheath body and inner cap.
The upper surface of described sheath body is also provided with seal membrane, and described seal membrane is sealed plastic film or aluminum thin film.
The cross section of described connection tube assumes diamond in shape, square, oval or circular configuration.
Described inner cap is the hollow cover body structure supported by flake aluminum.
This utility model has the following advantages:
1, by adopting tube for transfusion to install air deflector additional, can realize directly increasing transfusion directly in transfusion bag, reducing the use amount of transfusion bag, economical environment-protective.
2, by adopting air deflector, what it is such that medicinal liquid can be unidirectional inputs medicinal liquid from transfusion bag toward human body in, and can avoid infusing causes the phenomenon of backflow because of reasons such as height, ensure that the safety and hygiene of transfusion.
3, by adopting air deflector can the principle of positive and negative dress, medicinal liquid conveniently can be entered in transfusion bag, and transfusion can be avoided to flow backwards transfusion bag, cause transfusion and extraneous contact to pollute and infuse, effectively ensure that the quality of transfusion, facilitate easy to operate.
4, the cross section of connection tube assume diamond in shape, square, oval or circular configuration, the material usage of connection tube reduces, and reduces the bonding area with transfusion bag simultaneously, reduces production cost further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of tube for transfusion of the present utility model;
In figure: 1-transfusion bag, 2-tube for transfusion, 3-air deflector, 4-connection tube, 5-inner cap, 6-seal membrane, 7-sheath body, 8-check valve diaphragm.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As Fig. 1, shown in Fig. 2, a kind of novel transfusion bag dosing mouth composite cover, it comprises transfusion bag 1, tube for transfusion 2 and air deflector 3, tube for transfusion 2 is provided with above described transfusion bag 1, the lower end of described tube for transfusion 2 is provided with connection tube 4, connection tube 4 lower end is plugged in transfusion bag 1, connection tube 4 is connected with transfusion bag 1 inside, the upper end of described tube for transfusion 2 is provided with air deflector 3, described air deflector 3 comprises sheath body 7, check valve diaphragm 8 and inner cap 5, sheath body 7 is fixedly installed on the upper surface of tube for transfusion 2, inner cap 5 is set in the inner side of sheath body 7, check valve diaphragm 8 is arranged between sheath body 7 and inner cap 5, air deflector 3 can prevent medicinal liquid from flowing backwards outside transfusion bag 1, effectively avoid the contaminated problem of medicinal liquid, ensure that the safety and sanitation of transfusion, the port of described air deflector 3 is also provided with seal membrane 6, described seal membrane 6 is sealed plastic film or aluminum thin film.Wherein, seal membrane 6 traditional sealing means can be adopted directly to weld or spiral-lock in the feed liquor port of air deflector 3, also can adopt can connect open simply paste method.By arranging seal membrane 6, further avoid environmental contaminants and entering in transfusion bag 1.
Further, the upper surface of described sheath body 7 is also provided with seal membrane 6, and described seal membrane 6 is sealed plastic film or aluminum thin film.
Further, the cross section of described connection tube 4 assumes diamond in shape, square, oval or circular configuration, and the material usage of connection tube 4 reduces, and reduces the bonding area with transfusion bag 1 simultaneously, reduces production cost further.
Further, described inner cap 5 is the hollow cover body structure supported by flake aluminum, is convenient to spike pierces, thus can more easily, conducting quickly.
