[0025] As Figures 1 to 4 shown, a thrombus prevention system based on adaptive closed-loop control of patient body temperature includes a thrombus pump main body 1, a temperature control module, and a leg sleeve 2 with a temperature adjustment function. A leg sleeve interface 3 is provided at a position close to the hand-held part of the thrombus pump housing 1-1, and it is connected to the leg sleeve 2 with a temperature adjustment function through a corresponding tracheal joint.

[0026] Specifically, assembly holes 1-14 are provided on the left and right sides of the leg sleeve interface 3, and contact placement holes 1-16 are provided on the upper and lower sides; a first connector 3-1 is provided in the middle of the leg sleeve interface 3, and the first connector 3-1 can pass through the circular through-hole 1-12.

[0027] It further includes a second connector 3-2 for cooperative use. The first connector 3-1 and the second connector 3-2 are detachably matched. Contacts 1-9 are cooperatively provided on the first connector 3-1 and the second connector 3-2, and the contacts 1-9 are made of a conductive material. A power supply device 3-3 connected to the contacts 1-9 is provided on the first connector 3-1 and / or the second connector 3-2. The contacts 1-9 achieve conductive heating by introducing current and utilizing the resistance heating effect.

[0028] Specifically, a power supply device 3-3 connected to the contact 1-9 is provided on the first connector 3-1 and / or the second connector 3-2. The contact 1-9 conducts electric heating by introducing current and utilizing the resistance heating effect. Through the conductive contact 1-9 and the power supply device 3-3, the tracheal connector can conduct electric heating on the introduced gas by itself, and can also supply power for heating the corresponding leg sleeve 2 with a temperature adjustment function connected thereto.

[0029] Preferably, the first connector 3-1 and the second connector 3-2 are made of a heat-conducting material, so that after the contact 1-9 is electrically heated, the heat can be quickly transferred to all parts of the first connector 3-1 and the second connector 3-2, so that the first connector 3-1 and the second connector 3-2 themselves can also be better used in a low-temperature environment, and the gas flow is more stable.

[0030] The contact 1-9 is made of a magnetic material. When the first connector 3-1 and the second connector 3-2 are close to each other, the magnetic interaction between the contacts 1-9 will help them fit together more tightly, which can not only reduce the errors and misalignments during the connection process, but also improve the stability of the tracheal connector during operation, and prevent accidental disconnection caused by vibration or external force as much as possible. Magnetic materials usually have good electrical conductivity, and current can flow more smoothly between the contacts 1-9. When current is introduced, the contact 1-9 can more effectively convert electrical energy into heat energy, so as to achieve rapid and uniform heating. Magnetic materials usually also have good heat conduction performance. When the contact 1-9 generates heat through the resistance heating effect, these heats can be transferred to other parts of the tracheal connector more quickly, so as to achieve more uniform and efficient heating.

[0031] As Figure 5 shown, the leg sleeve 2 includes a leg sleeve body 2-1 and an electric heating film 2-6, and the electric heating film 2-6 is provided on the side of the airbag 2-4 close to the leg.

To improve the binding effect of the leg sleeve 2, it is not easy to fall off, and the corresponding treatment effect can be better achieved.

[0032] At least two sections of airbags 2-4 are provided on the other side of the leg sleeve 2, and generally three sections of airbags 2-4 are provided. And the provided airbags 2-4 gradually become larger from bottom to top, which is more in line with the shape of the human leg and has a better binding effect and pressing effect.

[0033] The outlet of the ventilation pipeline 2-5 of the airbag 2-4 is arranged between the magic tape 2-3 and the airbag 2-4 of the leg sleeve 2; the ventilation pipe is connected to the second connecting pipe 3-222 of the corresponding joint. This design makes full use of the corresponding space and reduces the volume of the product. An electrothermal film 2-6 is arranged on the side of the airbag 2-4 close to the leg. So as to better heat the leg sleeve 2. Naturally, the electrothermal film 2-6 is generally a low-temperature electrothermal film 2-6, so that the patient will not feel too high temperature and has an excellent use experience in a low-temperature environment.

[0034] An external circuit 2-7 of the electrothermal film 2-6 is arranged between the airbag 2-4 and the magic tape 2-3; the external circuit 2-7 is connected to the contact 1-9 of the second connector 3-2. That is, when designing accordingly, a separate circuit can be designed to be connected to the second connector 3-2, or it can be integrated with the design of the airbag 2-4. The external circuit 2-7 is attached to the ventilation pipeline 2-5 for wiring, effectively reducing the volume of the product. Overall, the power supply and heating requirements are realized through the second connector 3-2. Embodiment
