Description
Technical field
This utility model relates to a kind of transfusion bag, is specifically related to a kind of transfusion be applicable to medical procedure, belongs to medical field.
Background technology
Transfusion is a kind of common treatment means, the one-time infusion tube that for Mu Qian, major part medical institutions are used is all to need manually regulation and stop, so, at serious symptom coma patient, infant patient, or time patient falls asleep unconscious through long-term infusion, transfusion bag is at the state of no supervision in fact, once medicine is totally lost, when nobody is in time with changing transfusion bag or extracting syringe needle again, will produce blood back phenomenon, serious meeting causes air to enter vein, cause thromboembolism, jeopardize patient vitals；
And prior art is provided can the transfusion bag of automatic stopping infusion, although really and truly can play self-braking effect, but, himself structure complexity very, not only for manufacturing difficulty for medical apparatus and instruments factory, exploitation, manufacturing cost big, simultaneously, once using, the cost of patient fluid infusion will be greatly increased, so can not be widely adopted, and in a kettle of transfusion bag, put into this one of buoy be automatically stopped method, for Mu Qian relatively simple for structure, not only convenient manufacture, the increase of cost simultaneously is not too many；
nullBut，The buoy automatic stopping infusion bag of prior art，Still there is a series of problem，Such as disclosed in Chinese patent 200920140045.3，It it is a kind of ball float，And the such structure of ball-type is and instability in actual use，Can not very ensure stopping infusion，Anti-return blood and the generation of thromboembolism，The most also change the original structure dripping kettle，Add enterprise development cost，Therefore itself and be unfavorable for actually used，And the buoy structure disclosed in Chinese patent 200820017454.X，Although have employed lower thin and upper thick taper，But buoy itself easily rocks in a liquid，Therefore when liquid is fewer and feweri，Can not ensure that buoy can be directed at the liquid outlet dripping kettle equally，Still it is unfavorable for actually used，And the buoy structure disclosed in Chinese patent 201310410166.6，Although bottom adds center of gravity bar，Can ensure that alignment drips the liquid outlet of kettle，But in actually used，It is the heaviest and affect buoyancy that buoy is likely to be due to again center of gravity bar，Simultaneously，Smaller owing to dripping the volume of kettle itself，Raising the nose above water to breathe and a medicine for easily stop droplet kettle inlet instillation of buoy，Have influence on whole transfusion bag and go out the speed of liquid，This point embodies particularly evident when infusion suspension (having little granule medicament in liquid).
Summary of the invention
The purpose of this utility model is, it is provided that a kind of rational in infrastructure, and reliable stopping infusion does not affect the automatic stopping infusion bag of transfusion speed, to overcome the deficiency of prior art simultaneously.
This utility model realizes the technical scheme of its purpose:
A kind of automatic stopping infusion bag it include transfusion bottle, tube for transfusion and air inlet pipe are connected with transfusion bottle, have on tube for transfusion and drip kettle, it is additionally provided with backstop buoy in dripping kettle, described backstop buoy has buoyancy pallet, and the lower end of buoyancy pallet is taper tappet, and the end of taper tappet is balancing gravity block, taper tappet has hollow cavity, and the card of buoyancy pallet has some groups of netted open-end holes positioned opposite.
The periphery of described taper tappet has annular shirt rim.
Angle α between described annular shirt rim and taper tappet is 10 ° ~ 60 °.
The periphery of described buoyancy pallet is evenly distributed with some backstop pins.
Described tube for transfusion is positioned to drip and has, below kettle, the vent branch communicated therewith, and vent branch has plug.
After using structure of the present utility model, kettle is dripped owing to having on tube for transfusion, it is additionally provided with backstop buoy in dripping kettle, described backstop buoy has buoyancy pallet, and the lower end of buoyancy pallet is taper tappet, and the end of taper tappet is balancing gravity block, buoyancy pallet ensure that buoy is suspended in when liquid abundance and drips in kettle, balancing gravity block ensure that the taper tappet moment vertically downward simultaneously, it is not easy to rocks, and facilitates taper tappet and coordinating of dripping kettle liquid outlet.
nullDue to taper tappet, there is hollow cavity again，The card of buoyancy pallet has some groups of netted open-end holes positioned opposite，This spline structure is advantageous in that，Taper tappet is owing to being hollow structure，The buoyancy of the most whole backstop buoy is considerably improved，And buoyancy pallet has some groups of netted open-end holes，So，Drip the medicine that kettle inlet enters，Just directly card from buoyancy pallet can enter directly into the inner chamber dripping kettle，Kettle inner chamber is dripped without entering into from buoy and the gap dripped between kettle as the transfusion bag of conventional buoy structure，Thus do not interfere with the transfusion speed of whole transfusion bag，Ensure that the therapeutic effect of entirety，That particularly embodies when infusion suspension is particularly evident，Simultaneously，Owing to buoyancy pallet does not interferes with transfusion speed，The most just can be when reality manufactures，Buoyancy pallet must be accomplished as far as possible close to dripping kettle inner chamber，So，Buoyancy and the stability of whole buoy are strengthened the most further.
nullAnd the periphery of taper tappet has annular shirt rim，Angle α between described annular shirt rim and taper tappet is 10 ° ~ 60 °，This spline structure is advantageous in that，Relative to the simple liquid outlet relying on taper tappet to block a kettle，After having installed annular shirt rim additional，The effect of closure can become apparent from，Stopping infusion can be completely secured，The flowing of air can also be stopped，Simultaneously，Owing to there is angle between annular shirt rim and taper tappet，So when taper tappet slides into the liquid outlet dripping kettle，Annular shirt rim can preferably be fitted liquid outlet，Sealing effectiveness is more preferable，And when running into external force，Annular shirt rim can play certain self-locking action，Prevent taper tappet from skidding off，Ensure stopping infusion and the flowing of air，Further ensure that the safety of patient，The material of annular shirt rim can be medical silica-gel or medical grade rubber etc.，The most both will not hinder to slip at taper tappet and drip kettle liquid outlet，Can preferably fit liquid outlet inwall simultaneously，Realize maximum sealing effectiveness.
And the periphery of described buoyancy pallet is evenly distributed with some backstop pins; this spline structure is advantageous in that, in the case of reality is infused, patient often walks about with infusion bottle; so; drip kettle certainly will also can be driven, cause the backstop buoy of inside to rock, under this state; taper tappet is to be not easy to match with the liquid outlet dripping kettle; therefore, backstop pin can be when rocking
No matter all angles can prop up the inwall dripping kettle, substantially reduce rocking of backstop buoy, it is ensured that using effect of the present utility model.
Meanwhile, described tube for transfusion is positioned to drip and has, below kettle, the vent branch communicated therewith, and vent branch has plug, when transfusion will be complete, after taper tappet blocks the liquid outlet dripping kettle, plug can be extracted so that vent branch and ft connection, so, the liquid that tube for transfusion is positioned at below a kettle just can continue in the patient, can either reduce drug waste, remains too much liquid in it also avoid tube for transfusion simultaneously, when medical personnel collect recovery, liquid drips everywhere, brings inconvenience.
After have employed said structure, this utility model is for the transfusion bag of conventional structure, have greatly improved, both have employed simplest structure, the most do not change the structure of original transfusion bag, reach again good using effect, saved enterprise development manufacturing cost, also patient will not be constituted economic pressures simultaneously.
