Problems solved by technology

[0002] In clinical practice, one or two assistants are usually required to squeeze the patient's knee joint capsule, patella, and popliteal fossa with bare hands when performing knee joint cavity pumping treatment. The squeezing efficiency is not high and labor costs are wasted
Moreover, the assistant cannot accurately achieve the required extrusion pressure during the operation: if the extrusion pressure is too small, the fluid pumping will not be complete; Security risks
At present, medical institutions generally lack this kind of knee joint cavity pumping airbag device

Abstract

The invention provides an auxiliary knee joint cavity liquid-pumping gasbag device. The auxiliary knee joint cavity liquid-pumping gasbag device comprises a gasbag assembly, a fixed assembly and an inflation assembly. The gasbag device can be conveniently adjusted according to the sizes and shapes of knee joints of different patients to guarantee the optimal squeezing effect and using comfort. Anoperator can complete needed inflation and deflation work simply with one hand; meanwhile, air pressure values can be displayed to guarantee that the air pressure is within a safe range, and a patientis prevented from being injured due to excessive pressure. If the auxiliary knee joint cavity liquid-pumping gasbag device can be applied clinically on a large scale, the waste of labor resources medically can be reduced, the efficiency of medical work is improved, the efficiency of the knee joint liquid-pumping operation is improved, and the occurrence rate of complications is reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an airbag device for assisting knee joint cavity pumping. Background technique [0002] Clinically, when performing knee joint cavity pumping treatment, one or two assistants are generally required to squeeze the patient's knee joint capsule, patella, and popliteal fossa with bare hands. The squeezing efficiency is not high, and labor costs are wasted. Moreover, the assistant cannot accurately achieve the required extrusion pressure during the operation: if the extrusion pressure is too small, the fluid pumping will not be complete; Security risks. Medical institutions generally lack this knee joint cavity pumping air bag device at present. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides an auxiliary knee joint cavity pumping airbag device, which can effectively complete the ...
