Abstract
The utility model discloses a valve-shaped infusion device capable of stopping blood from flowing back, which comprises a Murphy's dropper, an infusion tube and one-way valves. The hemispherical valve (4) is mounted in the Murphy's dropper (1), and each spherical surface consists of a trisect valve block (5) capable of being separated under pressure. The valve-shaped infusion device overcomes the shortcoming of easy flowing back of blood of existing infusion devices, and has the advantages of simple structure and production technique, low cost, remarkable effect and capabilities of being widely applied to blood infusion and liquid infusion, relieving psychological burden of patients, and reducing labor intensity of nursing staff.
Description
Technical field
This utility model relates to field of medical products, a kind of more precisely device that is used for preventing at venous transfusion backflow of blood.
Background technology
Transfusion, blood transfusion are important and commonly used methods in the hospital clinical treatment.The present method that adopts: liquid is through Mo Feishishi dropper, tube for transfusion, syringe needle, the afferent veins blood vessel.The blood back phenomenon can not appear generally speaking, but necessary sometimes carry out blood pressure measurement on the transfusion limbs simultaneously, when the sphygomanometer cuff is tied up above transfusion; The liquid person is holding bottle when going to toilet; When liquid is totally lost, in time do not pull up syringe needle, at this moment the blood back phenomenon will occur, the lighter causes stress to the patient, and blood back forms thrombosis, blocks tube for transfusion.Weight person if thrombosis comes off, enters blood circulation, causes serious malpractice.Though have the patent of anti-return, anti-backflow transfusion device to occur at present successively: in Maufee type dropper, to add and put ball float, pin type valve, all, do not see enforcement so far because of reasons such as technical sophistication, production difficulties.
Summary of the invention,
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of structure, simple, the obvious results valve shape non-return blood infusion set of production technology are provided.
The purpose of this utility model adopts following technical measures to realize: well-known, the valve practical function of human heart li is a check valve, and this utility model is as design starting point.A kind of valve shape non-return blood infusion set, form by Mo Feishishi dropper, tube for transfusion, one-way valve, it is characterized in that: the Maufee type dropper upper end is liquid input tube, the lower end is an outlet tube, and the 1-5 one-way valve is housed in the Maufee type dropper, and valve is made hemispherical with nontoxic, rubber-like rubber or plastic sheeting, sphere becomes the discerptible valve block of trisection pressurized, the bottom is shaped on oval funnel in the dropper, and funnel top and dropper fuse, and funnel tube is in outlet tube.
Remarkable result of the present utility model: structure, production technology are simple, with low cost, and effect is remarkable, can extensive use in blood transfusion, transfusion, alleviate outpatients mental state burden and nursing staff's labor intensity.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structure chart of this utility model valve.
Below in conjunction with accompanying drawing this utility model is further elaborated.
The specific embodiment
Referring to figure, Maufee type dropper 1 upper end is a liquid input tube 2, the lower end is an outlet tube 3,1-5 one-way valve 4 is housed in the Maufee type dropper, valve is made hemispherical with nontoxic, rubber-like rubber or plastic sheeting, and sphere becomes the discerptible valve block 5 of trisection pressurized, and the bottom is shaped on oval funnel 6 in the dropper, funnel top 7 fuses with dropper, and funnel tube 8 is in outlet tube.
