Abstract

The utility model relates to a disposable pressurizing apparatus for blood transfusion and infusion, belonging to a clinical medical instrument. The three openings of a three-way pipe (2) are respectively sheathed with a needle head (1), an air inlet pipe (3), and a sealing sleeve (5); an air filter (7) and an air driving sac (8) are connected with the lower part of the sealing sleeve (5); an air inlet port (9) is arranged on the surface of the air driving sac (8); the end opening of the air filter (7) extending into the chamber of the sealing sleeve (5) is sheathed with a one-way valve (6); a disinfecting cotton ball and filtering sponge are respectively arranged in the air inlet pipe (3) and the air filter (7); the whole apparatus is arranged in a sealing plastic bag after disinfected. The utility model has the advantages of disposable use, convenient pressurizing in fast blood transfusion and infusion, small size, convenient operation, and no restriction by place, and can effectively prevent cross infection.

Description

Disposable pressurizing apparatus for blood transfusion and infusion

This utility model belongs to a kind of clinical treatment apparatus.

In clinical practice, usually need to rescue, as treatments such as major operation, hemorrhagic shock, neurocranial surgery, dehydrations, need import blood or liquid apace, reach the purpose of rescuing and treating.Existing technological means is sphygomanometer balloon pressurization blood transfusion.Need sterilization earlier during use, the interface linking does not match, uses repeatedly easy cross infection again.Push tube for transfusion, waste time and energy, be subjected to place restriction etc. with hands during transfusion.

The purpose of this utility model is that manufacturing is a kind of simple in structure, easy to operate, cheap, disposable pressurization blood transfusion and infusion device.

Realize that above purpose is such; It mainly is the syringe needle in the socket air inlet suitable for reading of tee T, the side muzzle taps into trachea, the air inlet pipe another port is plugged with cap sleeve, be plugged with sterilized cotton ball in it, the end opening socket sealing shroud of tee T, sealing shroud lower end socket air strainer, air strainer lower end are socketed with the purging capsule.The upper port that air strainer stretches into the sealing shroud intracavity is connected to check valve, and the sealing shroud intracavity is equipped with the filtration sponge, and purging capsule surface has an air inlet.Whole device is sealed in the plastic bag after sterilization.

Advantage of the present utility model is; Clinical disposable use, fast pressurization is convenient during blood transfusion and infusion, volume is little, easy to operate, take, be not subjected to condition restriction such as place at any time, make easy, cheap, of many uses, meet hygienic requirements, can effectively prevent cross infection.

This utility model is realized by accompanying drawing and following embodiment.

Accompanying drawing is a structural representation.

The available non-toxic plastic of whole device is made, syringe needle (1) is the available metal syringe needle also, syringe needle (1) that tee T (2) upward overlaps and air inlet pipe (3) and sealing shroud (5) all are tight fits, cap sleeve (4) clogs air inlet pipe (3) another port, the available one section valve inside of check valve (6) of air strainer (7) upper end entangles, upper port is shut, and uses to such an extent that sharp sword cuts a pocket knife seam with the valve inside side.Purging capsule (8) is a spherical shell and flexible.When using this device, unpack, syringe needle (1) is vertically passed bottle stopper, block air inlet (9) extruding purging capsule (8) with thumb, gas passes through air strainer (7), the effect of check valve (6), gas does not reflux.Block extruding again after decontroling air inlet (9) slightly, so repeatedly, pressure of the inside of a bottle constantly increases, and reaches till the required flow.As not pressurizeing, open end cap cover (4) but natural inflow, after finishing, abandon.

Claims

Disposable use pressurization blood transfusion and infusion device belongs to a kind of clinical treatment apparatus, it is characterized in that; Socket syringe needle suitable for reading (1) at tee T (2), the side muzzle taps into trachea (3), air inlet pipe (3) another port is plugged with cap sleeve (4), be plugged with sterilized cotton ball in it, the end opening socket sealing shroud (5) of tee T (2), sealing shroud (5) lower port socket air strainer (7), it is socketed with purging capsule (8) down again, the upper port that air strainer (7) stretches into sealing shroud (5) intracavity is with check valve (6), purging capsule (8) surface has an air inlet (9), and whole device is sealed in the plastic bag after sterilization.
