When used specifically, the hematoma compression arm sleeve 1 is first put on the arm of the patient with hematoma, and a suitable strip airbag 1.3 for pressurization is selected according to the location of the hematoma, and then the selected strip airbags 1.3 are connected in series in a head-to-tail manner using a transition connecting tube 3, and the air inlet and outlet 1.4 on one of the strip airbags 1.3 (usually the middle one) is connected to the inflation pressurization tube 4, and the terminal air inlet and outlet 1.4 on the end strip airbag 1.3 is blocked with a sealing cover. In this way, the forearm hematoma can be accurately positioned and compressed, and the force is relatively concentrated locally, and can be adjusted according to the dissipation of the patient's hematoma and the comfort level.

Then, the pressure value and time of the pressurization are set by the display adjustment module 2.2 of the pressurization host 2, and the processor 2.1 controls the air pump 2.3 to perform inflation and pressurization. The pressure information in the hematoma pressurization arm sleeve 1 is output to the processor 2.1 in real time and displayed by the display adjustment module 2.2; during the pressurization process, if the hematoma expands, the air pump 2.3 can be controlled by the processor 2.1 to increase the inflation volume, so as to achieve the effect of dissipating the hematoma. If the patient's limbs and back of the hand are obviously swollen, the air can be appropriately deflated and decompressed, and there is no need to re-bind and bandage during the whole process. If the hematoma does not expand, the principle is to maximize the comfort of the patient.

As shown in FIG4 , in this embodiment, the pressurization host 2 further includes a pneumatic pressure switch 2.5, which is arranged on the inflation and pressurization tube 4, and is connected to the processor 2.1.
