A charging port 18 for supplementing power of the energy storage battery is reserved on the pressure regulating panel 17. Through the built-in energy storage battery, the continuous power supply of the device is ensured, and the power can be supplemented through the charging port 18, avoiding the inconvenience and energy waste caused by the traditional power cord.

[0034] Although the massage bag 2 can directly contact the patient's skin, in order to improve the comfort of the patient, a velvet layer is arranged on the surface of the fixing belt 1. The edge of the velvet layer is fixedly connected with the fixing belt 1, and the massage bag 2 is arranged between the velvet layer and the fixing belt 1. The edge of the velvet layer and the fixing belt 1 can be directly fixedly sutured, and can also be detachably connected by means of a zipper, adhesion, snap fastener and the like, so as to be easily disassembled and washed and maintained. In this way, the velvet layer not only improves the comfort of the patient, but also is convenient to disassemble and wash, maintains the hygiene and cleanliness of the device, and reduces the risk of cross infection.

[0035] Working principle: the utility model discloses a PICC catheterization post -use pressure -generating device for preventing venous thrombosis, when using, first, the fixing band 1 is set on the arm of patient, and is fixed through magic son 15 and magic mother 16 cooperation;Then through the pressure regulating panel 17 on pressure regulating box 4 set up the working pressure of inflation pump 5, massage time and massage program, the controller sends control signal according to the set program combination input parameter, first air inlet valve 8 opens, inflation pump 5 is inflated to two inflatable bags 3 in the same massage bag 2, make the massage bag 2 towards the patient arm direction and rise, extrude the arm of patient, deflate after keeping a period of time;Then first air inlet valve 8 is closed, and second air inlet valve 9 is opened, and inflation pump 5 is inflated to two inflatable bags 3 in the other massage bag 2, so that the massage bag 2 rises to the arm of patient, deflate after keeping a period of time;The above steps reciprocating cycle, the arm of patient is periodically pressurized and relaxed massage, so as to reach the effect of extruding blood of limbs and preventing venous thrombosis.

[0036] [example 2]

[0037] Please refer to Figures 6-7 The difference between the embodiment and example 1 is that the layout of the massage bag 2 and the inflation pipeline is different in this embodiment to realize various massage requirements. Specifically, the massage bag 2 in the embodiment is provided with two rows of massage bags, each row is provided with two massage bags 2, forming a layout of two rows and two columns, i.e. four massage bags. One inflatable bag 3 is arranged in each massage bag 2, and one of the inflatable bags 3 in each row is communicated with the first air inlet pipe 6 through the first branch pipe 10, and the other inflatable bag 3 in each row is communicated with the second air inlet pipe 7 through the second branch pipe 11. The end of the first air inlet pipe 6 is provided with a first three-way valve 13, and the other two ways of the first three-way valve 13 are communicated with the two first branch pipes 10 respectively; the end of the second air inlet pipe 7 is provided with a second three-way valve 14, and the other two ways of the second three-way valve 14 are communicated with the two second branch pipes 11 respectively, and the first three-way valve 13 and the second three-way valve 14 are electrically connected with the controller.

[0038] When the first three-way valve 13 and the second three-way valve 14 simultaneously guide gas to the two inflatable bags 3 in the respective row, the massage effect of the synchronous rising of the massage bags 2 in the same row can be realized, and the arm of the patient is uniformly extruded and relaxed as described in example 1; when the controller switches the communication ports of the three-way valves to alternately inflate one inflatable bag 3 in the first row and one inflatable bag 3 in the second row, the massage effect of the alternate rising of the two massage bags 2 in opposite directions can be realized, the interest and interactivity of the massage are improved, and better relaxation effect and blood circulation promoting effect are achieved.

[0039] Obviously, the described embodiments are part of the embodiments of the present application, not all. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
