Description
Technical field
This utility model relates to infusion bag opener, particularly a kind of highly reliable residual few flip-shell infusion bag opener.
Background technology
Transfusion bag is by bag and infusion bag opener are welded together to form an entirety, in welding process, by the restriction of joint geometry or welding procedure, may cause be welded with residue and residual stay in transfusion bag or welded seal poor.In use, medical personnel need to be thrust in transfusion bag by transfusion needle and liquid could be derived, under existing technical conditions, the mouth of pipe majority of tube for transfusion is equipped with aluminium-plastic combined cover, then need aluminum material to tear before using, syringe needle could be thrust in plastic plug, but aluminum material may tear and causes producing irregular opening in the process of tearing, easy scuffing medical personnel, also can produce some plastic residues and be mixed in medicinal liquid and pollute medicinal liquid when punctures plastic plug.
And tube for transfusion syringe needle is when penetrating in transfusion bag, sometimes can exceed certain length, when medicinal liquid liquid level is lower than tube for transfusion needle, medicinal liquid cannot flow out, thus cause waste or lessen the curative effect.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides highly reliable residual few flip-shell infusion bag opener that a kind of structure is simple, easy to use, this device good seal, reliable clamping and can reduce liquid residual in transfusion bag.
The purpose of this utility model is achieved through the following technical solutions: a kind of highly reliable residual few flip-shell infusion bag opener, it comprises welding base, tube for transfusion and seal cover, tube for transfusion is arranged on welding base, seal cover is arranged on tube for transfusion, welding base bottom has conduction hole, and welding base and tube for transfusion junction have shoulder hole, and conduction hole is communicated with shoulder hole, in the macropore of shoulder hole, sealing ring is installed, in sealing ring, is provided with pilot hole.
Described welding base is rounded diamond, has several grooves at four sides.
Described sealing ring is arranged in the macropore of shoulder hole by interference fit.
Described pilot hole is tapered blind hole, and its outside diameter is greater than the diameter of tube for transfusion syringe needle, and its central diameter is less than the diameter of tube for transfusion syringe needle.
Described seal cover has a slot cover, slot cover both sides have rotary axis groove, and be provided with rotation cover by interference fits in slot cover, rotation cover and rotary axis groove corresponding position are provided with rotating shaft.
Distance bottom described seal cover top to shoulder hole macropore is less than tube for transfusion syringe needle and penetrates into length in sealing ring, and the distance bottom seal cover top to shoulder hole aperture is greater than tube for transfusion syringe needle and penetrates into length in sealing ring
This utility model has the following advantages: of the present utility model.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of highly reliable residual few flip-shell infusion bag opener;
Fig. 2 is seal cover front sectional view.
In figure, 1-welds base, 2-tube for transfusion, 3-sealing ring, 4-pilot hole, 5-seal cover, 6-rotating shaft, 7-rotation cover, 8-groove, 9-conduction hole, 10-shoulder hole, 11-slot cover, 12-rotary axis groove.
Detailed description of the invention
Be further described this utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of highly reliable residual few flip-shell infusion bag opener, it comprises welding base 1, tube for transfusion 2 and seal cover 5, tube for transfusion 2 is arranged on welding base 1, in the present embodiment, described welding base 1 is rounded diamond, several grooves 8 are had at four sides, seal cover 5 is arranged on tube for transfusion 2, in the present embodiment, described seal cover 5 has a slot cover 11, slot cover 11 both sides have rotary axis groove 12, by interference fits, rotation cover 7 is installed in slot cover 11, rotation cover 7 and rotary axis groove 12 corresponding position are provided with rotating shaft 6, conduction hole 9 is had bottom welding base 1, welding base 1 has shoulder hole 10 with tube for transfusion 2 junction, conduction hole 9 is communicated with shoulder hole 10, sealing ring 3 is installed in the macropore of shoulder hole 10, in the present embodiment, described sealing ring 3 is arranged on by interference fit in the macropore of shoulder hole 10, pilot hole 4 is provided with in sealing ring 3, pilot hole 4 is tapered blind hole, its outside diameter is greater than the diameter of tube for transfusion syringe needle, its central diameter is less than the diameter of tube for transfusion syringe needle, in the present embodiment, distance bottom described seal cover 5 top to shoulder hole 10 macropore is less than tube for transfusion syringe needle and penetrates into length in sealing ring 3, distance bottom seal cover 5 top to shoulder hole 10 aperture is greater than tube for transfusion syringe needle and penetrates into length in sealing ring 3.
Work process of the present utility model is as follows: coordinated with transfusion bag by welding base 1 and weld together, the welding base 1 of rounded diamond shape can make welding base 1 contact with transfusion bag well, groove 8 can reduce welding base 1 and the contact area of transfusion bag, avoids transfusion bag because causing failure welding too greatly by heat transition contraction or solder side thus affect sealing.
When needs are infused, exerting a force upward to rotation cover 7 makes it 6 rotate to expose pilot hole 4 around the shaft, then tube for transfusion syringe needle is penetrated in transfusion bag by pilot hole 4, due to thin bottom pilot hole 4, transfusion needle can be easy to puncture sealing ring 3 and avoid producing residue, because pilot hole 4 outside diameter is greater than the diameter of tube for transfusion syringe needle, central diameter is less than the diameter of tube for transfusion syringe needle, can ensure that tube for transfusion syringe needle can easily thrust sealing ring 3 and avoid producing residue, and tube for transfusion syringe needle can be good to be clamped in pilot hole 4 and can to ensure that medicinal liquid is not subject to air pollution and can not reveals, due to the restriction of tube for transfusion 2 length, tube for transfusion needle can only be positioned at shoulder hole 10 aperture, after tube for transfusion syringe needle installs by transfusion bag hang upside down aloft to infuse, when medicinal liquid is soon totally lost, medicinal liquid in bag can be collected by conduction hole 9, to reduce the medicinal liquid remained in bag.
