Technical field
This utility model relates to medicine and hygiene fields, the transfusion device that uses when more specifically relating to a kind of the transfusion.
Background technology
At medicine and hygiene fields, transfusion is the conventional means in the medical treatment at present, is extensive use of disposable infusion set the patient is carried out venous transfusion, have the vein medicine easy to operate, improve curative effect, prevent the positive role of cross infection.Current general infusion set has following drawback, first, the used transfusion device of infusing adopts packed or bottled form mostly, and transfusion set does not possess self closing device, therefore in transfusion, medical personnel will nurse the decline situation of the medicinal liquid of transfusion device inside at any time, in order to avoid because of the medicinal liquid deficiency, in time do not change dressings or stop injection and cause accident.The second, the inconvenient two kinds of medicinal liquids of current general infusion set are infused jointly or are dripped medicinal liquid midway.The 3rd, current general infusion set filter can not the filtering medicinal liquid and air in the following insoluble microparticle of 10 μ m and pathogenic bacteria, and enter the infant blood circulation greater than the microgranule that the microgranule of 6-8 μ m enters adult's blood circulation or 3 μ m, will cause adverse consequences.These insoluble microparticles in blood vessel of hiding stop up in the blood vessel of internal organs such as the heart, brain, lung, kidney, liver, eye, deposit, and can cause in various degree tissue necrosis and pathological changes; The thrombosis that microgranule forms affects microcirculation in human body again, makes several years or cardiovascular and cerebrovascular diseases such as apoplexy, thromboembolism may occur after decades, so that cause sickness rate height and the rejuvenation of present cardiovascular and cerebrovascular disease.
The utility model content
This utility model proposes a kind of safe transfusion device that makes things convenient for liquid feeding at the deficiencies in the prior art.
According to an aspect of the present utility model, a kind of liquid precision filter infusion set that ends automatically is provided, comprise the perforator that connects successively by infusion tube, liquid-feeding tube, actuator, accurate filter and puncture needle, infusion tube between perforator and the liquid-feeding tube is provided with parking lamp, the top of liquid-feeding tube is provided with dropper, the cross section of liquid-feeding tube is provided with and only rises bank, only rise bank and liquid-feeding tube the bottom the space in be provided with floating plug, the bottom of floating plug is inlaid with latex ring medicated cap, latex ring medicated cap is provided with the annulus of latex thin film for one side, the bottom of liquid-feeding tube is provided with drain pipe, and it is relative with drain pipe that latex ring medicated cap is provided with the one side of latex thin film.
When the liquid-feeding tube, can close parking lamp and control transfusion by opening, need not to regulate by actuator; When another set of transfusion device is communicated with liquid-feeding tube, when carrying out second kind of medicinal liquid infusion simultaneously in parallel, can control the infusion of first kind of medicinal liquid according to practical situation by parking lamp; In case of emergency, in time close the generation that parking lamp can be avoided fortuitous event.Medicinal liquid enters liquid-feeding tube by perforator
In.Only rising the bank middle part is an annulus, and annulus is horizontally disposed with, and annulus is connected with the ring wall of liquid-feeding tube by three plastics barred bodies, and it is fixing within the specific limits with floating plug only to rise bank, and the position is too high with the rising of medicinal liquid liquid level to prevent floating plug; Floating plug is gear-like, and one side is convex surface, and one side is concave surface; Be provided with latex ring medicated cap in the concave surface of floating plug, latex ring medicated cap is for simultaneously being provided with the latex annulus of latex thin film, and the whole plug of latex ring medicated cap is in the concave surface of floating plug, and the latex thin film of latex ring medicated cap is over against the liquid outlet of liquid-feeding tube bottom.In infusion process, because medicinal liquid is to the buoyancy of floating plug, floating plug can not touch liquid outlet, and when medicinal liquid will be failed to the greatest extent, floating plug was not subjected to the buoyancy of medicinal liquid, latex ring medicated cap in the floating plug contacts with the liquid outlet of liquid-feeding tube, the latex thin film is close to liquid outlet, thereby the sealing liquid outlet makes air not enter into tube for transfusion under the liquid outlet, thereby prevent the air admission human body, realize safe infusion.Actuator is used for regulating the speed that medicinal liquid is carried.Accurate filter filters medicinal liquid, by puncture needle the patient is carried out intravenous injection at last.
In some embodiments, the oblique upper of liquid-feeding tube is provided with filling opening.The convenient two kinds of medicinal liquids of filling opening are infused simultaneously, perhaps increase the transfusion medicinal liquid midway.
In some embodiments, perforator is provided with steam vent, and the upper end of steam vent is provided with baffle plate.Baffle plate is bigger, when medical personnel infuse in reality, operates more conveniently, can easier perforator be injected in the infusion bottle.
In some embodiments, floating plug is gear-like.The floating plug of gear-like makes things convenient for passing through of medicinal liquid.
In some embodiments, only rising the bank middle part is an annulus, and annulus is horizontally disposed with, and annulus is connected with the ring wall of liquid-feeding tube by three plastics barred bodies.
In some embodiments, be Long Circle when parking lamp is in closure state, the top of parking lamp is provided with through hole, and the bottom of parking lamp is provided with lower through-hole, and the inside of parking lamp is provided with first fixation clamp and second fixation clamp.
In some embodiments, the external diameter of floating plug is less than the internal diameter of liquid-feeding tube.Make floating plug can be in liquid-feeding tube free floating.
