Description

Medical flapper-type transfusion tee T

This utility model relates to a kind ofly to be imported medium in the human body or is passed to infusion apparatus on the human body, particularly a kind of medical flapper-type transfusion tee T.

CN2091160Y discloses a kind of pressurizing infusion set, it be by a tee T and up and down each check valve constitute, the tee T side pipe can connect syringe, and with the bolt sealing, the check valve controlling liquid makes the maintenance downflow direction up and down at ordinary times, when needing pressure transfusion, it is connected between former transfusion device lower end nipple and the intravenous needle, and the tee T side pipe connects syringe, under the control of check valve, liquid suction syringe, pressurization is injected into vein again.There is following weak point in this pressurizing infusion set: 1. complex structure, and part is more; 2. poor reliability; 3. sealing is poor.

The purpose of this utility model provides a kind of medical flapper-type transfusion tee T, it has simplified described prior art constructions design, reduced part and replaced check valve with the flap valve structure, overcome described the deficiencies in the prior art part effectively, the shape of this product, structure or its are in conjunction with having proposed a kind of practical new technical scheme that is suitable for.

The concrete formation that can realize this utility model above-mentioned purpose is, medical flapper-type transfusion tee T, form by tee T, unidirectional flap valve and elasticity plug, the difference that goes out of itself and prior art is: the upper and lower end of tee T respectively is connected to a unidirectional flap valve, the upper end of tee T is shaped on the lobe lower cover of unidirectional flap valve, the lower end of tee T is shaped on the lobe loam cake of unidirectional flap valve, and the elasticity plug is connected on the side pipe termination.Unidirectional flap valve is made up of lobe loam cake and lobe lower cover and the valve that floats on wherein, and the elasticity plug is the automatic blocking switch.

Accompanying drawing 1 is a structure principle chart of the present utility model;

Accompanying drawing 2 is the sketch map of dentation valve;

Accompanying drawing 3 is the structural representation of elasticity plug, among the figure:

The unidirectional flap valve 3--of 1--tee T 2--lobe loam cake

4--lobe lower cover 5--side pipe 6--elasticity plug

7--dentation valve

Accompanying drawing

1,2 and 3 constitutes a complete embodiment of the present utility model, below in conjunction with drawings and Examples in detail this utility model is described in detail: medical flapper-type transfusion tee T, form by tee T (1), unidirectional flap valve (2) and elasticity plug (6), the outstanding difference of itself and prior art is: the upper and lower end of tee T (1) respectively is connected to a unidirectional flap valve (2), the upper end of tee T (1) is shaped on the lobe lower cover (4) of unidirectional flap valve (2), the lower end of tee T (1) is shaped on the lobe loam cake (3) of unidirectional flap valve (2), and elasticity plug (6) is connected on side pipe (5) termination.Unidirectional flap valve (2) is made up of lobe loam cake (3) and lobe lower cover (4) and the valve (7) that floats on wherein, elasticity plug (6) is the automatic blocking switch, when the needle tubing of syringe props up the elasticity plug from the right center partly the time, the compression spring, operator are pushing syringe simultaneously, and the medicinal liquid in the syringe is entered in the side pipe.

Using method of the present utility model is the lower end that the unidirectional flap valve of medical flapper-type transfusion tee T upper end is connected to existing general infusion set, the unidirectional flap valve of medical flapper-type transfusion tee T lower end connects intravenous needle, during pressure transfusion, the needle tubing of another syringe is inserted the elasticity plug, in the process of injection liquid, under the effect of pressure, flap valve in the unidirectional flap valve in upper end upwards floats, seal the unidirectional flap valve in upper end, flap valve in the unidirectional flap valve in lower end floats downwards, open the unidirectional flap valve in lower end, medicinal liquid is gone into intravenous needle by side pipe is laggard; During drawing liquid, under the effect of negative pressure, the switching of two unidirectional flap valves is just in time opposite with above-mentioned action, and the liquid in the transfusion device enters syringe behind the side pipe of this tee T.Use of the present utility model, can reach under the integral asepsis condition blood or medicinal liquid are pressurizeed in the input patient body fast, automatically preventing from effectively the to pressurize backflow and the medicinal liquid of blood transfusion or loading liquid process medium-sized vein blood upwards flows along liquid-transport pipe-line, the patient is implemented effective rescue as early as possible, win the treatment opportunity of success.

To sum up state, the utility model is compared with aforementioned prior art, have simple in structure, the design Rationally, easy to operate, treatment fast, reliability and sealing be the advantage such as good all.
