Abstract
The utility model relates to a disposable transfusion apparatus, belonging to the technical field of inputting medium into the human body or the instrument acting on the human, comprising a terminal filter, a Y type pipe, a transfusion pipe and a sealing cover, which is characterized in that: the Y type pipe is arranged above the terminal filter; the lower opening of the Y type pipe is communicated with the terminal filter form into a whole body; a upper opening is communicated with the transfusion pipe and form into a whole body; the other opening is an intravenous drugs inlet; the sealing cover is arranged on the intravenous drugs inlet. The purpose of the arrangement of the Y type pipe is that: when fast or additionally feeding drugs are needed, the drugs can be directly pushed through the opening of the Y type pipe by the injector; the drugs enter the vein through the terminal filter, thus the fine particle pollution of the mainline drugs are effectively prevented. Using the utility model in the transfusion can make all the drugs, which need to enter the vein, go through the terminal filter to insure the drugs enter to the human vein safely and steadily. The utility model has the advantages of reasonable structure, simple use, safe and steady drugs, effectively preventing the fine particle pollution and other advantages.
Description
(1) technical field
This utility model relates to a kind of disposable transfusion device, belongs to import medium in the human body or be passed to technique with the apparatus field on the human body.
(2) background technology
Transfusion particle is meant the non-metabolism granule foreign that enters human body in infusion process.Its diameter generally has only 1-25um, also can be 50-300um or larger particle.Naked eyes can only be seen the microgranule that 50um is above.The source of particle contamination: the influence of (1) medicine material: injection and infusion solution raw material, because production technology is unreasonable, sneak into impurity, make microgranule enter medicinal liquid; (2) water for injection is impure; (3) production process is polluted; (4) air-polluting influence; (5) solution bottle, rubber closure influence: rubber closure strips off and microgranule is arranged; (6) influence of transfusion operation: comprise cutting ampoule, feeding operations etc.The harm of particle contamination: when the injection that contains microgranule injects Venous system, enter right atrium, behind heart, blood is pressed into pulmonary artery, the continuous branch of tremulous pulse, caliber dwindles gradually, forms the huge blood capillary piping of pulmonary, bigger microgranule just may rest in the blood capillary piping, causes obstruction.The most predispose to damage is positions such as lung, brain, liver, kidney.Cause following pathological change (1) occluding vascular, cause blood supply insufficiency, tissue ischemia, anoxia, even tissue necrosis.(2) foreign body rests in the tissue of a certain position, is surrounded and propagation and form granuloma by macrophage, and the lung internal granuloma is the most common.(3) because erythrocyte is collected on the microgranule, form thrombosis, cause blood vessel embolism and phlebitis.(4) thrombocytopenia and anaphylaxis appear; (5) some microgranule can also be because of stimulating tissue to be inflamed and lump etc.The disposable transfusion device that uses in the present venous transfusion, because the end-filtration net has been installed, significantly reduced the pollution of microgranule, but venous transfusion only is one of method of intravenously administrable, and in many cases, need direct intravenous injection medicine, be about to medicine and directly inject vein, as when giving emergency treatment to a patient, need performance drug effect rapidly, win when rescuing, the perhaps requirement of some Therapeutic Method, perhaps some diagnostic test needs vein to inject medicine or the like, when carrying out above operation, need to separate tube for transfusion and syringe needle (scalp acupuncture), connect empty needle and inject medicine.Make medicinal liquid directly enter vein owing to separate, increased the risk of particle contamination greatly by the ultimate filter on the tube for transfusion.
(3) summary of the invention
This utility model is for remedying the deficiencies in the prior art, provide a kind of rational in infrastructure, use simply, can effectively prevent the medicine of particle contamination to enter the novel transfusion device of vena systemica.
This utility model is finished by following technical measures:
Above the ultimate filter of transfusion device Y tube is set, the Y tube under shed communicates with ultimate filter and is that one, a upper shed communicate with tube for transfusion and is one, and another opening is the intravenous pharmacy inlet, which is provided with capping.
Transfusion device is a disposable transfusion device.
Transfusion device is made up of tube for transfusion, hair Fei Shi dropper, adjustable clamp, ultimate filter.
This utility model is provided with Y tube on ultimate filter top, its objective is, when the quick administration of need or when adding medicinal liquid in addition, can be with the opening of syringe by Y tube, directly medicinal liquid is advanced, enter vein, effectively prevented the particle contamination of intravenous drug by ultimate filter.Using this utility model can make all need enter the venous medicinal liquid in transfusion all passes through ultimate filter, has guaranteed that medicinal liquid enters human vein with security and stability.
The utlity model has rational in infrastructurely, use simply, it is complete stable and effectively prevent advantage such as particle contamination that medicinal liquid is sent out.

(5) specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Structure as shown in drawings, 4 centimeters are provided with Y tube on ultimate filter 4 tops of transfusion device 1, under shed communicates with ultimate filter and for one, a upper shed communicates with tube for transfusion and is one, another opening is an intravenous pharmacy inlet 6, and capping 7 is arranged on it.Transfusion device is a disposable transfusion device.Transfusion device is made up of tube for transfusion 1, hair Fei Shi dropper 2, adjustable clamp 3, ultimate filter 4.During clinical use, medicinal liquid enters human vein by transfusion device, when need are given the quick dosing of patient, takes off the capping on the Y tube, and syringe makes medicinal liquid enter human vein with security and stability by ultimate filter by intravenous pharmacy inlet injection liquid.
Claims (1)
1, a kind of novel transfusion device is characterized in that, on the ultimate filter top of transfusion device Y tube is set, the Y tube under shed communicates with ultimate filter and is one, one upper shed communicates with tube for transfusion and is one, and another opening is the intravenous pharmacy inlet, which is provided with capping.
