technical field

The invention relates to the field of medical devices, in particular to a deep vein antithrombotic massager.

Background technique

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.

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 re-inflate, 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. Aiming at the problems existing in the prior art, the present invention provides a deep vein antithrombotic preventive treatment that can display the pressure value more accurately, adopt touch control, set the working mode, and adjust the working intensity. At the same time, the multi-chamber airbag adopts a unique tear-off design, which is convenient to fix on the patient's limb.

Detailed ways

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the present invention will be further described in detail below in conjunction with the drawings in the embodiments of the invention. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts relevant to the present invention are shown in the accompanying drawings but not all content.

The embodiments of the present invention help to prevent the formation of thrombus and limb edema, and can directly or indirectly treat many diseases related to blood and lymph circulation.

A kind of deep vein antithrombotic prevention treatment instrument provided by the embodiment of the present invention, as shown in Figure 1, Figure 2, Figure 3, comprises:

Main engine 1, multi-chamber airbag 3 and gas connection pipe 2, described main engine 1 is connected with described multi-chamber airbag 3 by described gas connection pipe 2 as a whole.

The host 1 is provided with a control circuit 107, an input module 109, an output module 110, a power supply module 111, an air pump 106 and a solenoid valve group 108; All are connected to the control circuit 107; the host 1 is provided with an indicator light 103, a touch display device 101, an airway socket 102, an external power plug 105 and a power switch 104.

The multi-chamber airbag 3 is set to a shape suitable for the lower limbs of the human body, and a hook and loop is provided at the interface of the multi-chamber airbag 3, and the multi-chamber airbag 3 is designed as a tear-off type, so that the multi-chamber airbag 3 can be fixed more conveniently. in the human body.

The touch display device 101 is specifically a TFT liquid crystal color touch screen. Through the touch display device 101, the massage mode, massage pressure value, and massage time can be set according to the patient's needs, and the massage pressure value can be accurately displayed at the same time.

The control circuit 107 adopts a single-chip microcomputer circuit. There are single-chip microcomputer 10701, amplification circuit 10702, isolation circuit 10703, gas pressure sensor 10704 on the described control circuit. Amplifying circuit 10702 and isolation circuit 10703 are all connected to single chip microcomputer 10701.
