Abstract
The utility model provides a disposable transfusion system, is including the bottle plug puncture assembly that connects gradually, dropping funnel subassembly and infusion pipeline, bottle plug puncture assembly includes needle cover, sheath, and the needle is sheathe in and is equipped with the pjncture needle, the sheath cover is established outside the needle cover, and it is protruding that needle cover afterbody is equipped with a hemisphere, and the sheath afterbody is equipped with a corresponding hemisphere recess, the protruding and hemisphere groove phase gomphosis of hemisphere, the sheath divide into canned paragraph and segregation section, the canned paragraph is equipped with plastic fastening piece with the segregation section junction, plastic fastening piece respectively with canned paragraph and segregation section fixed connection, segregation section and needle cover pass through threaded connection. The beneficial effects of the utility model are that destroy plastic fastening piece hard when using, unscrew the segregation section of sheath again, could be with pjncture needle use that come out, so during the secondary use, the doctor will discover obviously there is destroyed vestige, has avoided medical malpractice's emergence.
Description
Technical field
This utility model relates to field of medical technology, is specifically related to a kind of disposable infusion set.
Background technology
General its structure of disposable transfusion device of commercially selling is all fairly simple, and each parts are socketed to form mutually, again to be turned one's head by used disposable transfusion device utilization, cause more malpractice thus so there are some lawless persons; In addition, when infusion-completed, need timely syringe needle to be extracted, otherwise air enters into patient's intravenous, entail dangers to life time serious.
Utility model content
The purpose of this utility model is to provide a kind of disposable infusion set, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of disposable infusion set, comprise the bottle stopper puncture assembly connected successively, dropper component and infusion pipeline, described bottle stopper puncture assembly comprises needle guard, sheath, needle guard is provided with puncture needle, described sheath is set in outside needle guard, it is protruding that needle guard afterbody is provided with a hemisphere, sheath afterbody is provided with a corresponding hemisphere groove, hemisphere projection and hemisphere groove tabling, described sheath is divided into canned paragraph and segregation section, described canned paragraph and segregation section junction are provided with plastic fastening, described plastic fastening is fixedly connected with segregation section with canned paragraph respectively, segregation section and needle guard are threaded connection, described dropper component comprises dropping funnel and liquid outlet, also comprises gear-like floating plug, and gear-like floating plug is positioned at dropping funnel, is provided with a cylinder plug below gear-like floating plug.
The further effect of this utility model is: the diameter of described cylinder plug is equal with the diameter of liquid outlet.
This utility model further effect is: also comprise flow regulator and transfusion needle.
This utility model further effect is: described dropping funnel also comprises inlet.
The beneficial effects of the utility model firmly destroy plastic fastening in use, turned on by the segregation section of sheath, could come out puncture needle use again, so when secondary uses, doctor will find that there is obviously destroyed vestige, avoids the generation of malpractice; In addition, when transfusion completes, gear-like floating plug is under gravity and atmospheric pressure effect, and cylinder plug tightly can block liquid outlet, air is entered less than in the infusion pipeline under liquid outlet, thus prevents air from entering human body, achieve safe infusion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model bottle stopper puncture assembly.
In figure: 1-bottle stopper puncture assembly, 2-inlet, 3-dropping funnel, 4-gear-like floating plug, 5-cylinder plug, 6-liquid outlet, 7-infusion pipeline, 8-flow regulator, 9-transfusion needle, 101-puncture needle, 102-needle guard, 103-sheath, 104-plastic fastening, 1031-segregation section, 1032-canned paragraph.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making under creative work prerequisite
The every other embodiment obtained, all belongs to the scope of this utility model protection.
Refer to Fig. 1 and Fig. 2, in this utility model embodiment, a kind of disposable infusion set, comprise the bottle stopper puncture assembly 1 connected successively, dropper component and infusion pipeline 7, described bottle stopper puncture assembly 1 comprises needle guard 102, sheath 103, needle guard 102 is provided with puncture needle 101, described sheath 103 is set in outside needle guard 102, it is protruding that needle guard 102 afterbody is provided with a hemisphere, sheath afterbody is provided with a corresponding hemisphere groove, hemisphere projection and hemisphere groove tabling, described sheath 103 is divided into canned paragraph 1032 and segregation section 1031, described canned paragraph 1032 is provided with plastic fastening 104 with segregation section 1031 junction, described plastic fastening 104 is fixedly connected with segregation section 1031 with canned paragraph 1032 respectively, segregation section 1031 and needle guard 102 are threaded connection, firmly destroy plastic fastening 104 in use, again the segregation section 1031 of sheath 103 is turned on, could be come out puncture needle 101 use, so when secondary uses, doctor will find that there is obviously destroyed vestige, avoid the generation of malpractice.
Described dropper component comprises dropping funnel 3 and liquid outlet 6, also comprise gear-like floating plug 4, gear-like floating plug 4 is positioned at dropping funnel 3, be provided with a cylinder plug 5 below gear-like floating plug 4, during not enabled, cylinder plug 5 blocks liquid outlet 6, when medicinal liquid drips in dropping funnel 3, along with the liquid level of medicinal liquid rises, gear-like floating plug 4 floats under the effect of buoyancy, automatically opens liquid outlet 6; When medicinal liquid is totally lost, gear-like floating plug 4 is under gravity and atmospheric pressure effect, and cylinder plug 5 can tightly block liquid outlet 6, air is entered less than in the infusion pipeline 7 under liquid outlet 6, thus prevents air from entering human body, achieve safe infusion.
The diameter of described cylinder plug 5 is equal with the diameter of liquid outlet 6.
Also comprise flow regulator 8 and transfusion needle 9.Described dropping funnel 3 also comprises inlet 2.
To those skilled in the art, obvious this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or basic feature, can realize this utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in this utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
