Description

The convenient transfusion device of disposable one-way

Technical field:

This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of disposable transfusion device.

Background technology:

Disposable transfusion device is the intravenously administrable gravity tubulature passage that extensive use is gone up in medical treatment.Being applied as treatment and giving emergency treatment to a patient of it plays an important role.Ensure people's health and lives safety, in the past, the present and the future had in long period of time can not substituted superiority.The disposable transfusion device that uses at present has two kinds: a kind of is to add exhaust manifolds in addition as the hole perforator; Another kind is the diplopore transfusion device, and exhaust manifolds are one with perforator mutually.Make up a prescription all by syringe puncture once more or repeatedly dosing of liquid bottle stopper or pressurization.This dosing form causes medicine to be infected by antibacterial or other pollutant at the rubber closure that repeatedly punctures easily, also can cause medicinal liquid excessive from air inlet sometimes.The needle handle of existing transfusion device all is flat plastic, and the success rate of disposable acupuncture treatment is not very high always, and particularly the nurse is under the situation that hands wets, and needle handle can be very sliding, uses also very inconvenient.General disposable transfusion device carries out vein when pushing away medicine at needs, joint need be pulled up, and pushes away medicine with syringe then, and the chance and the one man operation that can increase infection when carrying out the plug of joint are constant.

The utility model content:

This utility model has designed the convenient transfusion device of a kind of disposable one-way, and it has medicinal liquid can be not excessive, infection chance is few, the advantage easily of having an acupuncture treatment.This utility model is made up of perforator 1, tube for transfusion 2, funnel 3, acupuncture treatment pipe 4, and the lower end of perforator 1 is connected with the upper end of tube for transfusion 2, and the other end of tube for transfusion 2 is connected with the upper end of acupuncture treatment pipe 4, and funnel 3 is arranged on the middle part of tube for transfusion.

Described perforator 1 is provided with three ducts, the duct of promptly infusing, air inlet duct, dosing pressurization duct, and except that infusion hole was kept straight on, all the other two holes were all drawn by hard plastic tube with the right angle; Also be provided with chemical feed pipe 1-3, exhaustor 1-2 on the perforator 1, air inlet pipe is by perforator hard plastic tube 6 and filter plastic conduit 7, and flexible plastic tube 8 are formed, the inner of filter plastic conduit 7 is provided with the unidirectional flap valve of a membrane type, the plastic conduit cecum is flat solid, there is an aciculiform aperture at/3rd places outside central point, and cecum is with a thin film cover outward, and positive center also is provided with a pin sample aperture; The lower end of filter plastic conduit 7 is provided with filter 5, is provided with two layers of filter paper 5-1 and active carbon layer 5-2 in the filter 5, and active carbon layer 5-2 is arranged between the two layers of filter paper 5-1.

Described chemical feed pipe 1-3 is made up of plastic conduit, valve inside formula plastic conduit and flexible plastic tube outside the dosing duct, wherein the valve inside plastic conduit has the opening that is connected with syringe outward, there are a rubber closure 10 and plug loop 11 to be connected in the inner slightly thin cecum that is of plastic conduit of opening chemical feed pipe outward, the hard plastic tube sidewall has a pin sample aperture, has an elastic film ring set to press lip on aperture outward.In dosing and when pressurization, washed ring set open by external force, and medicine and gas are washed ring set open by external force, and medicine is closed by self elastic force, and the medicinal liquid outflow is obstructed.

This utility model has been added a chemical feed pipe 1-3 than existing general infusion set, chemical feed pipe 1-3 is used for dosing and pressurization, and do not need direct rubber closure to carry out once more or multiple punching to medicine bottle, reduced bottle contaminated probability of interior medicine, and be provided with a unidirectional flap valve 9 in this chemical feed pipe 1-3, make that chemical feed pipe 1-3 is one-way flow, and can not allow medicine flow backwards, medicine is overflowed.Increased active carbon layer 5-2 in this utility model in the filter of exhaustor 1-2, active carbon has the moisture absorption, sterilization, fungi-proofing effect, and the air that enters medicine bottle is filtered, and has purified the air that enters medicine bottle, has reduced contaminated probability.The utlity model has the advantage that contaminated probability is low, medicine can not overflow.
