Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] Refer to Figures 1 to 5As shown in the figure, an embodiment of the present utility model provides a thrombus pump 10, which includes a main machine device 100, an airbag device 200 and a connection component 300; the main machine device 100 is provided with an inflation hole 121; the airbag device 200 is detachably connected to the inflation hole 121; the connection component 300 includes a first magnetic component 310 and a second magnetic component 320. The first magnetic component 310 is arranged inside the main machine device 100, and the second magnetic component 320 is connected to the airbag device 200. The airbag device 200 is detachably connected to the main machine device 100 through the magnetic attraction cooperation between the first magnetic component 310 and the second magnetic component 320.

[0032] When using the thrombus pump 10 of this embodiment, first, the airbag device 200 is sleeved on the patient's arm, and then the airbag device 200 is connected to the main machine device 100. At this time, the airbag device 200 is communicated with the inflation hole 121, and the airbag device 200 and the main machine device 100 are magnetically matched through the first magnetic component 310 and the second magnetic component 320. The main machine device 100 can inflate the airbag device 200 through the inflation hole 121; after use, the airbag device 200 can be conveniently separated from the main machine device 100.

[0033] In the thrombus pump 10 of this embodiment, the connection component 300 can realize the detachable connection between the airbag device 200 and the main machine device 100, thereby facilitating the separation of the airbag device 200 and the main machine device 100. The structure is simple and the use is convenient.

[0034] Specifically, the main machine device 100 includes an upper cover 110, a bottom shell 120, a sealing member 130 and an inflation component. The upper cover 110 and the bottom shell 120 enclose an installation space. The inflation component is arranged in the installation space. The sealing member 130 is arranged between the inflation hole 121 and the inflation component. The inflation hole 121 is arranged on the bottom shell 120, and the sealing member 130 is used to seal between the airbag device 200 and the inflation hole 121.

[0035] In this embodiment, after the inflation device is assembled with the upper cover 110 and the bottom case 120, the main device 100 forms a modular structure, which is convenient for separation and connection with the airbag device 200; after the airbag device 200 is connected to the main device 100, the inflation assembly can inflate the airbag device 200 through the inflation hole 121 to make the airbag device 200 expand to achieve the compression function. During the connection process between the airbag device 200 and the main device 100, the seal 130 can be hermetically connected to the airbag device 200 and the inflation hole 121 respectively to ensure the inflation airtightness of the main device 100. In one embodiment, the seal 130 is a rubber sealing ring. During the connection process between the airbag device 200 and the inflation hole 121, the seal 130 can deform and fill the gap between the airbag device 200 and the inflation hole 121, thereby improving the airtightness between the airbag device 200 and the inflation hole 121, avoiding air leakage, and maintaining the internal air pressure of the airbag device 200.

[0036] In one embodiment, the inflation assembly includes an air pump 141 and at least one air valve 142. The air pump 141 is connected to the air valve 142, and the air valve 142 is connected to the inflation hole 121.

[0037] In this embodiment, by arranging an air valve 142 between the air pump 141 and the airbag device 200, the air valve 142 can control the inflation of the airbag device 200. When the number of air valves 142 is multiple, the multiple air valves 142 are respectively connected to the air pump 141. At this time, the airbag device 200 can be connected to at least one air valve 142; when the airbag device 200 is respectively connected to the multiple air valves 142, by controlling the inflation of the airbag device 200 through different air valves 142, the inflation part of the airbag device 200 can be controlled. For example, multiple cavities are provided in the airbag device 200, and the multiple cavities are respectively connected to different air valves 142. By controlling the air valve 142 to deliver gas to different cavities, the adjustment function can be achieved.

[0038] It should be noted that the host device 100 further includes a control module. The signal of the control module is located in the installation space and is connected to the air pump 141 and the air valve 142. The control module is used to control the start and stop of the air pump 141 and the air valve 142. Specifically, the control module can be, but is not limited to, various PLCs (Programmable Logic Controllers, with the full name Programmable Logic Controller), STM32 (STM32 microcontrollers, which are 32-bit microcontrollers with an ARM Cortex-M core), single-chip microcomputers, FPGAs (Field Programmable Gate Arrays, with the full name Field Programmable Gate Array), ARMs (ARM processors, with the full name Advanced RISC Machine), etc. It is set inside the host device 100 and is used to directly control the device and obtain the operating status of the device.

[0039] In one embodiment, the inflation assembly further includes a battery 143, and the battery 143 is electrically connected to the air pump 141 and the air valve 142.

[0040] By arranging the battery 143 inside the host device 100, the battery 143 can supply power to the air pump 141 and the air valve 142, and the thrombus pump 10 can inflate the balloon device 200 in a state without an external power supply, and the use effect is good. Specifically, the battery 143 is preferably a rechargeable battery. During use, the battery 143 can be charged to achieve the energy storage function, which is convenient for improving the portability and use convenience of the thrombus pump 10. Of course, in some embodiments, the battery 143 can also be a dry battery. At this time, the battery 143 in the inflation assembly is preferably detachable, which is convenient for users to replace the new battery after the energy of the battery 143 is consumed.

[0041] Furthermore, the bottom case 120 is further provided with a first installation groove 122, and the first installation groove 122 is located in the installation space, and the first magnetic member 310 is embedded in the first installation groove 122.

[0042] In this embodiment, by arranging the first magnetic member 310 in the first installation groove 122, the combined structure of the first magnetic member 310 and the bottom case 120 can be made compact and the overall thickness can be reduced.

[0043] Specifically, the balloon device 200 includes a balloon body 210 and a fixed bottom plate 220. The fixed bottom plate 220 is connected to one side of the balloon body 210, and the second magnetic member 320 is connected to the fixed bottom plate 220.

[0044] In this embodiment, the airbag body 210 is a flexible structure and can realize the functions of expansion and contraction. The fixed bottom plate 220 is a rigid structure to ensure the stability when the airbag device 200 is connected to the host device 100. When the airbag device 200 is connected to the host device 100, the fixed bottom plate 220 is located between the airbag body 210 and the bottom case 120 to ensure that the fixed bottom plate 220 can be stably attached to the bottom case 120. Specifically, the airbag body 210 and the fixed bottom plate 220 can be fixedly combined by means such as bonding and snap connection.

[0045] Specifically, at least one nozzle 211 is connected to the airbag body 210. The fixed bottom plate 220 is provided with a connection hole 221. The nozzle 211 passes through the connection hole 221 and protrudes outward from the fixed bottom plate 220. The nozzle 211 is used to connect with the inflation hole 121.

[0046] With this setting, when the airbag body 210 and the fixed bottom plate 220 are assembled and positioned, the nozzle 211 of the airbag body 210 can be passed through the connection hole 221, and then the airbag body 210 and the fixed bottom plate 220 are attached and fixed. When the airbag device 200 is connected to the host device 100, the fixed bottom plate 220 is attached to the bottom case 120, and the part of the nozzle 211 protruding from the connection hole 221 is inserted into the inflation hole 121. In this way, the connection stability between the airbag device 200 and the host device 100 can be ensured. When the nozzle 211 is inserted into the inflation hole 121, the seal 130 can be sleeved on the nozzle 211 and hoop on the outer wall of the nozzle 211 under the elastic action. The seal 130 can seal between the inner wall of the inflation hole 121 and the nozzle 211. At the same time, the seal 130 can also assist in fixing the nozzle 211 and the host device 100 under the elastic action and is convenient for disassembly and assembly. After the nozzle 211 is connected to the seal 130, the airtightness between the airbag device 200 and the host device 100 can be ensured. Specifically, the first magnetic member 310 and the second magnetic member 320 are preferably circular magnets, and the first magnetic member 310 and the second magnetic member 320 are coaxially arranged. Since the circular magnets have N poles and S poles at the opposite ends in the axial direction, during the assembly process of the thrombus pump 10, the first magnetic member 310 and the second magnetic member 320 can be installed without complicated positioning, with a simple structure and improved installation convenience. Of course, the first magnetic member 310 and the second magnetic member 320 can also be bar magnets. At this time, the number of the first magnetic member 310 and the second magnetic member 320 is preferably multiple groups, and the multiple groups of the first magnetic member 310 and the second magnetic member 320 can be arranged at intervals along the wearing direction of the airbag body 210. By connecting the multiple groups of the first magnetic member 310 and the second magnetic member 320, the connection firmness between the host device 100 and the airbag device 200 can be effectively improved.

[0047] Further, the fixed bottom plate 220 is provided with a second installation groove 222, and the second installation groove 222 is arranged on the side of the fixed bottom plate 220 away from the host device 100, and the second magnetic member 320 is embedded in the second installation groove 222.

[0048] In this embodiment, by providing the second installation groove 222 on the side of the fixed bottom plate 220 away from the host device 100, after the second magnetic member 320 is connected to the second installation groove 222, the combined structure of the fixed bottom plate 220 and the second magnetic member 320 can be made compact. At the same time, when the first installation groove 122 is arranged on the side of the bottom case 120 away from the fixed bottom plate 220, and the second installation groove 222 is arranged on the side of the fixed bottom plate 220 away from the bottom case 120, the first magnetic member 310 and the second magnetic member 320 can be spaced and supported by the bottom case 120 and the fixed bottom plate 220 to prevent the first magnetic member 310 and the second magnetic member 320 from accidentally disengaging from the first installation groove 122 and the second installation groove 222; in addition, by arranging the opening of the first installation groove 122 on the side of the bottom case 120 away from the fixed plate 220, and arranging the second installation groove 222 on the side of the fixed bottom plate 220 away from the bottom case 120, when the first magnetic member 310 and the second magnetic member 320 are installed in place, the bottoms of the first installation groove 122 and the second installation groove 222 are then thin-walled structures, so that the distance between the first magnetic member 310 and the second magnetic member 320 is smaller, thereby effectively improving the magnetic attraction performance between the first magnetic member 310 and the second magnetic member 320, and further improving the connection firmness between the host device 100 and the airbag device 200.

[0049] In one embodiment, the number of the connection components 300 is multiple groups, and the multiple groups of connection components 300 are arranged at intervals along the extension direction of the airbag device 200.

[0050] It should be noted that in this embodiment, when the airbag device 200 is worn on the human arm, the extension direction of the airbag device 200 can be defined as the length direction of the arm wearing part, as Figure 2 shown, that is, the horizontal direction in the figure. At this time, by arranging the multiple groups of connection components 300 along the extension direction of the airbag device 200, a stable adsorption fixing force can be provided between the airbag device 200 and the host device 100 in the extension direction of the airbag device 200, so as to improve the connection strength between the airbag device 200 and the host device 100 and prevent the host device 100 from accidentally detaching, and the use effect is good.
