Deep-vein thrombus-prevention massaging instrument

Abstract

The invention relates to a deep-vein thrombus-prevention massaging instrument. The deep-vein thrombus-prevention massaging instrument is characterized by comprising a host, a multi-cavity airbag and agas connecting pipe, wherein a control circuit, an input module, an output module, a power supply module, an air pump and an electromagnetic valve group are arranged in the host; the input module, the output module, the power supply module, the air pump and the electromagnetic valve group are connected with the control circuit; and the host is provided with an indication lamp, a touch display device, an air guiding pipe socket, an external power supply plug and a power supply switch; and the air pump is connected with the multi-cavity inflation airbag through the electromagnetic valve group,and each airbag is connected with an electromagnetic valve. A gas pressure sensor is mounted on the control circuit, and a pressure value collected by the gas pressure sensor is corrected, so that theaccurate maintenance problem of a pressure numerical value is solved; working modes are selected according to the requirements, so that the requests of different patients on the treatment modes are solved; by utilizing a touch control manner, the operation is relatively simple and convenient; by utilizing a tearing design, the multi-cavity airbags can be conveniently fixed to limbs of a patient;and the deep-vein thrombus-prevention massaging instrument is small in volume, convenient to carry and low in cost.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a deep vein antithrombotic massager. Background technique [0002] Deep vein thrombosis refers to the abnormal coagulation of blood in the venous system, blocking a certain deep vein, resulting in venous return obstruction caused by thrombus, causing blood stasis and limb swelling. The incidence and mortality rate of deep vein thrombosis is high, second only to ischemic heart disease and stroke. 50% to 80% of patients have no early clinical manifestations. After the formation of deep vein thrombosis, it will cause tissue necrosis and local edema. If the thrombus falls off, it will easily cause fatal pulmonary embolism, which seriously threatens the life of the patient.

AI Technical Summary

Problems solved by technology

[0003] In traditional air wave therapy instruments, the air inlet and outlet of each airbag cavity are controlled by series-connected solenoid valves. Each solenoid valve has only two independent states of air intake and air outlet. When the next airbag is inflated, the previous airbag will be deflated first. Then inflate again, and finally reach the same air pressure as the current inflatable bag, and the air pressure cannot be accurately maintained during this process

In addition, the above-mentioned therapeutic apparatuses all have a single working mode, and cannot precisely adjust the working intensity.
