The fixing component includes a velvet tape arranged at the end of each branch of the airbag on one side of the airbag body and a branch end of each airbag on the other side of the airbag body for sticking and fixing with the velvet tape the hook belt;

The inflatable assembly includes a pressure gauge and a balloon air pump, the pressure gauge is connected to the airbag body through a first air guide tube, the balloon air pump is connected to the air bag body through a second air guide tube, Wherein the connection between the second airway tube and the balloon air pump is provided with an air valve.

Preferably, the length of the suede is greater than the length of the branches of the airbag.

Preferably, the fleece is provided with an extension section.

Preferably, the material of the fleece is nylon.

Preferably, the hook strap is made of nylon.

The airbag device used in the present invention can be conveniently adjusted according to the size and shape of the knee joints of different patients, so as to ensure the best extrusion effect and use comfort. The operator can complete the required inflation and deflation work with one hand, and the air pressure value can be displayed to ensure that the air pressure is within a safe range and avoid excessive pressure causing damage to the patient. If the present invention can be applied in a large amount clinically, it will reduce the waste of human resources in medical treatment, improve the efficiency of medical work, improve the efficiency of knee joint fluid pumping operation, and reduce the incidence of complications.

Detailed ways

The present invention will be further described below in conjunction with specific examples, so as to better understand the present invention.

Example

The present invention provides an airbag device for assisting knee joint cavity pumping fluid, as shown in Figure 1 and Figure 2, comprising an airbag assembly, a fixing assembly and an inflatable assembly, wherein,

The airbag assembly includes an airbag body 9 and a first airbag branch 5, a second airbag branch 6, a third airbag branch 7, and a fourth airbag branch 8. The first airbag branch 5 and the second airbag branch 6 are located on one side of the airbag body 9 , the third airbag branch 7 and the fourth airbag branch 8 are located on the other side of the airbag body 9, the third airbag branch 7, the fourth airbag branch 8 and the first airbag branch 5 and the second airbag branch 6 are formed along the airbag body The central axis of 9 is in a mirror image arrangement position corresponding to each other. The airbag body 9 and all airbag branches are on the same plane. The above-mentioned airbag branches are all flat airbag structures, and form an H-shaped airbag together with the airbag body 9.

The fixing assembly includes the first nylon velvet tape 1 and the second nylon velvet tape 2 that are located at the ends of the first air bag branch 5 and the second air bag branch 6, and are used at the ends of the third air bag branch 7 and the fourth air bag branch 8. Based on the fixed first nylon hook strip 3 and the second nylon hook strip 4, the first nylon velvet belt 1 and the second nylon velvet belt 2 have longer extensions than the first airbag branch 5 and the second airbag branch 6, In order to adjust the tightness when using the present invention, the first nylon velvet tape 1, the second nylon velvet tape 2, the first nylon hook tape 3, and the second nylon hook tape 4 can be pasted and fixed.

The inflatable assembly includes a pressure gauge 12 and a balloon air pump 14. The pressure gauge 12 is connected to the airbag body 9 through the first air guide tube 10, and the balloon air pump 14 is connected to the air bag body 9 through the second air guide tube 11, wherein the second air guide tube 11 is connected to the air bag body 9 through the second air guide tube 11. An air valve 13 is provided at the connection of the balloon air pump 9 . The two sides of the balloon air pump 14 are provided with one-way pistons, which can be squeezed to inflate the airbag body 9 through the second air guide tube 11, so that the "H" shaped airbag is inflated. The air valve 13 is a deflation switch, by opening the air valve 13, the second air guide tube 11 can be used to deflate the "H" shaped air bag.

The present invention is installed on the patient's knee joint when performing a liquid pumping operation. The back side of pressure gauge air guide pipe 10, air pump air guide pipe 11 is the inner surface of " H " shape air bag. Put the inner surface of the "H" shaped airbag close to the patient's skin, the airbag body 9 is located in the popliteal fossa of the patient, the first airbag branch 5, the second airbag branch 6, the third airbag branch 7, and the fourth airbag branch 8 are respectively along the patient's knee The inner and outer sides of the joint are fixed above and below the patella.
