Abstract

The utility model discloses a disposable infusion drainage device. The utility model provides with a transparent elastic ball; the two ends of the transparent elastic ball are provided with two one-way valves which are at the same direction and are provided moveable valves which can rotate around a central shaft; the two one-way valves are respectively connected with a puncture needle and a liquid bottle. When the elastic ball is extruded, the utility model can perform the quick infusion, drainage and blood changing; under the action of the one-way valves, the utility model can control the phenomenon of back flow, which can reduce the retrograde infection. The utility model has the advantages of simple operation, time saving, labor saving, simple structure and easy fabrication.

Description

Medical disposable infusion drainage apparatus

This utility model is a kind of disposable medical transfusion drainage system.

Existing disposable transfusion device only is used for transfusion, can not directly quicken transfusion, if by the transfusion fast of pressurizeing to the air-tight bottle injecting compressed air, then can may be pressed into human body because of Compressed Gas causes aeroembolism to cause death, and such complicated operation, take to carve and note gas-liquid face position in the liquid bottle.Existing breast, intraperitoneal drainage breast, ascites or air, the tricorn drainage of cerebrospinal fluid is that puncture needle is connected with one section rubber tube, is allowed to condition under the effect of natural pressure to flow out voluntarily.The drain site pressure is often less, carry out under strict aseptic condition by syringe gradation suction.Simultaneously, there is the hidden danger of retrograde infection in complicated operation like this.

The purpose of this utility model is a kind of transfusion drainage system of design, can be used for transfusion, transfusion fast, drain and exchange transfusion.

The purpose of this utility model is achieved in that this device is a transparent elastic force ball, elastic force ball two ends connect liquid bottle and puncture needle after a check valve is installed in the same way, check valve is made up of union joint, flap valve, axle, union joint internal fixation flap valve, and flap valve rotates around axle.

The new elastic force ball control ball internal pressure that adopts of this practicality, outwards press juice (gas) body aspirates liquid (gas) body at infusion bottle or drain position, a kind of design has multiple use, and is easy and simple to handle, reduces and infects, this apparatus structure is simple simultaneously, and is cheap, is easy to apply.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is a structure chart of the present utility model.

In conjunction with the accompanying drawings, the concrete condition of this utility model is described, the elastic force ball ［ 1 ］ of this transfusion drainage system is made by transparent non-toxic plastics, has elastic force, has graduation mark to indicate a milliliter number above, elastic force ball ［ 1 ］ one end has union joint ［ 2 ］, union joint ［ 2 ］ and elastic force ball ［ 1 ］ are tightly connected, and the close elastic force pommel of union joint ［ 2 ］ inwall is flap valve ［ 3 ］ fixedly, and flap valve ［ 3 ］ rotates around axle ［ 4 ］, slewing area constitutes a check valve in 45 °; Elastic force ball ［ 1 ］ other end is union joint ［ 7 ］, also is tightly connected with the elastic force ball, and its inwall leans on fixedly flap valve ［ 5 ］ of elastic force pommel, and flap valve ［ 5 ］ rotates around axle ［ 6 ］, and slewing area constitutes another check valve in 45 °.During use, with hands extruding elastic force ball, the ball internal pressure raises, flap valve ［ 5 ］ is closed, flap valve ［ 3 ］ is open, and liquid (gas) body extrudes the removal external force of loosing one's grip in the ball from union joint ［ 2 ］, negative pressure in the ball, flap valve ［ 5 ］ is open, and flap valve ［ 3 ］ is closed, and outside liquid (gas) body enters from union joint ［ 7 ］, liquid (gas) body of union joint ［ 2 ］ outer end is hindered by flap valve ［ 5 ］, can't backflow.

When this utility model was used to infuse, union joint ［ 7 ］ connected the medicinal liquid bottle after connecting Murphy's burette, and union joint ［ 2 ］ connects syringe needle, when needing transfusion fast, as long as can carry out with hands extruding elastic force ball, can accurately learn amount of infusion by the ball high scale.

When this utility model is used for drain, union joint ［ 7 ］ is connected thoracic-puncture needle, peritoneo-puncture needle or tricorn drainage needle, union joint ［ 2 ］ connects the liquid bottle, can carry out ascites pleural fluid, the tricorn drain, constantly extruding elastic force ball just connects sucking-off with breast, ascites, owing to stopping of flap valve ［ 3 ］, breast, ascites can't be backflowed, and the retrograde infection chance reduces.

When this utility model is used for the vein exchange transfusion, one cover transfusion drainage system union joint ［ 7 ］ is connected venipuncture needle, and union joint ［ 2 ］ connects the liquid bottle, extracts venous blood continuously out, another set of transfusion drainage system union joint ［ 2 ］ is connected intravenous needle, union joint ［ 7 ］ connects transfusion bottle, blood imported in the body, on one side blood drawing, blood transfusion on one side, equivalent is carried out, and a people can operate, and the contaminated probability of blood is also extremely low.

Claims

1, a kind of disposable medical transfusion drainage system, this device has a transparent elastic force ball, and elastic force ball two ends connect liquid bottle and puncture needle respectively, it is characterized in that elastic force ball two ends install a check valve in the same way; Check valve is by union joint, flap valve, and axle is formed, union joint internal fixation flap valve, flap valve rotates around axle.
