Abstract
The utility model discloses a needle for inserting a bottle for infusion. The needle comprises a needle stand (1), an infusion needle (2) and an air needle (3), wherein a liquid inlet (4) is arranged on the side wall of the infusion needle (2); a liquid outlet (6) is arranged on the lower end of the infusion needle (2); an air outlet (7) is arranged on the side wall of the air needle (3); projections (5) are arranged on the surfaces of both the infusion needle (2) and the air needle (3); an air inlet (8) is arranged at the lower end of the infusion needle (2); and the liquid inlet (4) is lower than the air outlet (7). The utility model has the beneficial effects that: the frequency of operation by medical staff is reduced, and the bottle inserting resistance is small; projections are arranged on the surfaces of the needle bodies, so that accidental falling of the inserting needle can be prevented; the contour lines on the needle bodies are all smooth fillet surfaces and can not cause falling of particles; and the height of the liquid inlet of the infusion needle is lower than that of the air outlet of the air needle, so that bubbles entering through the air needle can not enter the liquid inlet of the infusion needle.
Description
Technical field
This utility model relates to medical instruments field, and needle for inserting bottle is used in particularly a kind of transfusion.
Background technology
Existing needle for inserting bottle comprises split type and monoblock type, and split type is that transfusion needle, air needle are independent separately, non-integrative-structure; Because transfusion needle, the air needle product degree of split type transfusion device needle for inserting bottle are identical; So during clinical practice, can transfusion needle occur and air needle is positioned at sustained height, easily get into transfusion needle mouth by the bubble that air needle gets into this moment; Make water in the tube for transfusion, gas with advancing; Cause the interior liquid level of Murphy type burette of transfusion device to drop to nothing, cause air embolism, if observe untimely meeting crisis patient life security.Monoblock type is the form that transfusion needle, air needle are fixed together, and is a kind of channel structure arranged side by side that uses, and promptly transfusion needle and air needle are compound is one, to reduce cost, reduces the operation of medical workers number of times.But this monoblock type external diameter is bigger, and needle body is thick, and needle point is difficult to sharp, and it is big to insert the bottle resistance.
Existing needle for inserting bottle meets accident easily and comes off, and pollutes, also maybe delay treatment.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of and can reduce medical worker's number of operations, and it is little again to insert the bottle resistance, and can prevent that the transfusion of accidental from using needle for inserting bottle.
The purpose of this utility model realizes through following technical scheme:
Needle for inserting bottle is used in a kind of transfusion, and it comprises needle stand, transfusion needle and air needle, and transfusion needle and air needle are arranged at the left and right sides of needle stand respectively; The sidewall of transfusion needle is provided with inlet, and the surface of transfusion needle is provided with protuberance, and the lower end of transfusion needle is provided with liquid outlet; The sidewall of air needle is provided with the gas outlet; The surface of air needle also is provided with protuberance, and the lower end of transfusion needle is provided with air inlet, and the height of transfusion needle inlet is lower than the height of air needle gas outlet.
The edge of described inlet, gas outlet is smooth fillet.
Described protuberance outer surface is a smooth surface, and protuberance and junction, needle body surface are smooth fillet.
The utlity model has following advantage:
This utility model is a monolithic construction, and transfusion needle and air needle are separate, both less medical worker's number of operations, and it is little again to insert the bottle resistance; The needle body surface is provided with protuberance, can prevent the accidental of contact pin; Contour line on the needle body all is slick fillet surface, can not produce and compare particulate coming off; The height of transfusion needle inlet is lower than the height of air needle gas outlet, and has certain distance between two pins, can not produce the phenomenon of the bubble entering transfusion needle mouth of air needle entering.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is done further description:
As shown in Figure 1, needle for inserting bottle is used in a kind of transfusion, and it comprises needle stand 1, transfusion needle 2 and air needle 3; Transfusion needle 2 and air needle 3 are arranged at the left and right sides of needle stand 1 respectively; The sidewall of transfusion needle 2 is provided with inlet 4, and the surface of transfusion needle 2 is provided with protuberance 5, and the lower end of transfusion needle 2 is provided with liquid outlet 6; The sidewall of air needle 3 is provided with gas outlet 7; The surface of air needle 3 also is provided with protuberance 5, and the lower end of transfusion needle 2 is provided with air inlet 8, and the height of transfusion needle 2 inlets 4 is lower than the height of air needle 3 gas outlets 7.
The edge of described inlet 4, gas outlet 7 is smooth fillet.
Described protuberance 5 outer surfaces are smooth surface, and protuberance 5 is smooth fillet with junction, needle body surface.
