Adhesive pieces are provided on both sides of the endless belt body. Realize bundling on the affected part by bonding parts.

The adhesive is Velcro. It is easy and convenient to use the Velcro. It can be adjusted according to the size of the patient's knee.

The inflatable part is a manual air pump with a pressure indicator. Control the stable pressure without causing reflux of effusion. It can be used to display the inflation volume in real time to prevent product damage and personal injury caused by over-inflation. The safety range is marked on the indicator, and the over-inflation range is specially marked in red, which is safe and convenient to use. The air pump is ergonomically designed, easy to use, easy to press, and fast to inflate.

As one of the preferred modes of the present invention, the manual air pump is connected to the endless belt body through a rubber air tube. When not in use, the rubber air tube is detachable, small in size and easy to carry. It is made of medical rubber material and has a length of 20cm.

As one of the preferred modes of the present invention, the body of the annular belt is provided with a copper interface, and the copper interface is connected to the rubber air pipe.

A valve is set on the copper interface. Insert the rubber air tube directly when inflating, loosen the valve when deflated, and the gas will be released automatically and at a constant speed.

The outer surface of the endless belt body is a PU leather surface. It has good wear resistance and elasticity, and plays the role of shock absorption, anti-friction, impact resistance and tensile resistance.

The inner surface of the endless belt body is a pure cotton surface. It has little friction with the skin and is comfortable to use.

A plurality of ventilation holes are arranged on the endless belt body. Good air permeability, comfortable to use.

Compared with the prior art, the present invention has the following advantages: the present invention has good airtightness, good air permeability, wear resistance and impact resistance, and is comfortable to use; small in size, easy to disassemble and easy to carry; simple to operate; quick manual inflation, environmentally friendly and economical; automatic indication High pressure, explosion-proof, safe to use; automatic and uniform deflation; lasting and stable squeezing effect of effusion without causing effusion reflux, safe and reliable; effectively assisting surgeons in extraction of knee joint effusion and efficient use of medical human resources.

detailed description

The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

As shown in Figures 1 and 2, this embodiment includes an endless belt body 1 with a hollowed out part, an inflator, and a telescopic airbag layer 2; the telescopic airbag layer 2 includes a plurality of transverse airbags 4 and a plurality of longitudinal airbags 3, so The plurality of longitudinal airbags 3 are longitudinally arranged on the outer surface of the annular belt body 1 in turn, the transverse airbags 4 are elastically connected to two adjacent longitudinal airbags 3, and the longitudinal airbags 3 protrude outward after being inflated. The endless belt body 1 communicates with the stretchable air bag layer 2 , and the inflatable body is connected to the endless belt body 1 .

The stretchable airbag layer 2 can generate a reverse C-shaped extrusion force after being inflated, and can squeeze the knee joint effusion into the suprapatellar pouch in multiple directions, and the stretchable airbag layer 2 has good sealing performance, can generate stable pressure, and does not cause effusion backflow.

The size of the hollow part is 5cm×5cm, and it does not cover the position between the patella and the femoral condyle when used, and is used for the surgeon to extract the effusion.

The outer surface 7 of the endless belt body 1 is a PU leather surface. It has good wear resistance and elasticity, and plays the role of shock absorption, anti-friction, impact resistance and tensile resistance.

The inner surface 6 of the endless belt body 1 is a pure cotton surface. It has little friction with the skin and is comfortable to use.
