[0038] A pressing adjustment component 3 and a reset spring component 4 are installed on the fixed plate 1. The pressing adjustment component 3 includes an external threaded column 31 rotatably connected to the fixed plate 1. The lower end of the external threaded column 31 is threadedly connected to a movable sleeve 32. The bottom end of the movable sleeve 32 is clamped with a pressing block 34. The lower end of the fixed plate 1 is fixedly connected to a transparent limit cylinder 33 that slides relatively with the movable sleeve 32. A plurality of limit groups are equidistantly installed on the inner wall of the transparent limit cylinder 33. The limit groups include two pairs of electromagnetic telescopic columns 6.

[0040] A plurality of guide grooves are provided on the side wall of the movable sleeve 32, and a slide bar matching the guide grooves is fixedly connected to the inner wall of the transparent limit cylinder 33, and the slide bar is located between two horizontally adjacent electromagnetic telescopic columns 6;

[0041] The reset spring assembly 4 includes a housing 41, a movable platform 42 is slidably mounted in the housing 41, and a spring is mounted on the movable platform 42. A suitable spring is selected by a person skilled in the art for installation;

[0042] The bottom end of the housing 41 is rotatably connected with a lower rotating shaft 43, and the middle part of the movable platform 42 is rotatably connected with a docking rotating shaft 421 matching with the lower rotating shaft 43. The bottom end of the docking rotating shaft 421 is provided with a docking groove matching with the top end of the lower rotating shaft 43, and a frosted surface is provided in the docking groove. The top end of the lower rotating shaft 43 is provided with a hexagonal docking block matching with the docking groove. The docking rotating shaft 421 and the lower rotating shaft 43 can only be docked when the movable sleeve 32 is fully reset; when the movable sleeve 32 is fully reset, its top end is in contact with the lower end of the fixed plate 1;

[0043] The docking shaft 421 is fixedly connected to the middle of the clockwork spring, a driven gear 44 is installed at one end of the housing 41 located in the fixed plate 1, a rotating wheel 311 is installed at one end of the external threaded column 31 located in the fixed plate 1, and a tooth groove matching the driven gear 44 is provided at the outer end of the rotating wheel 311; a sliding hole with a built-in damping layer is provided in the middle of the top of the housing 41, an adjusting rod 422 is slidably connected in the sliding hole, and the bottom end of the adjusting rod 422 is rotatably connected to the top of the docking shaft 421;

[0044] When the spring is restored, the external threaded column 31 can be rotated through the lower rotating shaft 43, the docking rotating shaft 421 and the driven gear 44;

[0045] An adjusting cover 312 is installed at the top end of the external thread column 31 . The adjusting cover 312 is provided with a receiving groove matching the pressing block 34 . The pressing block 34 is made of medical resin.

[0046] The bottom end of the movable sleeve 32 is provided with a snap-fitting groove matching the upper part of the pressing block 34 , and the top end of the movable sleeve 32 is provided with a buffer groove matching the electromagnetic telescopic column 6 , and pressure sensors are installed in both the buffer groove and the snap-fitting groove.

[0047] It also includes an auxiliary working system, which includes a single chip microcomputer installed on the fixed plate 1, and the single chip microcomputer is connected to a timing module, a control module, a display module, a communication module and a power storage module; the power storage module is used for power supply, and a charging port matching the power storage module is provided on the fixed plate;

[0048] The timing module is used to record the pressing time and countdown. The side end of the fixing plate 1 is provided with an operation button for setting the timing time; the operation button can be used for countdown setting, mode selection of the control module and decompression confirmation;

[0049] The communication module is connected to a wireless communication module and an audible and visual alarm, and the wireless communication module is used for wireless connection with a user terminal; the user terminal includes an application program on a mobile terminal;

[0050] The control module is used to control the operation of the electromagnetic telescopic column 6; the monitoring module is used to collect monitoring data of the pressure sensor;

[0051] The display module is connected to the display screen and is used to display the timing of the timing module, the mode selection of the graded decompression mode and the comprehensive decompression mode, and the pressure data collected by the monitoring module.

[0052] Before using this solution, remove the pressing block 34 from the adjusting cover 312 and install it on the bottom of the movable sleeve 32; then, according to the usage scenario, select one or a combination of the strap 2, the Z-shaped bracket or the C-shaped bracket to fix the fixing plate 1 to the use position; the strap 2, the Z-shaped bracket, the C-shaped bracket, and the pressing block 34 must be disinfected before use;

[0053] After the fixing plate 1 is fixed, the pressing adjustment component 3 is adjusted to set the pressing pressure;

[0054] When adjusting the pressing adjustment component 3, the user rotates the external threaded column 31 to move the movable sleeve 32 downward, thereby applying pressure to the pressing part. During the pressurization process, the pressure data at the pressing block 34 collected by the pressure sensor is displayed on the display screen on the fixed plate 1;

[0055] When the pressure data reaches the required requirement, stop rotating the external threaded column 31 to complete the pressing setting;

[0056] Optionally, the user can set the device to automatically reduce pressure after a set time as needed;

[0057] When setting the automatic decompression, the user needs to press the adjustment rod 422 before adjusting the pressing adjustment component 3, so that the docking shaft 421 docks with the lower shaft 43, and then adjust the pressing adjustment component 3; during the adjustment process of the pressing adjustment component 3, the external threaded column 31 drives the driven gear 44 to rotate through the rotating wheel 311, thereby causing the docking shaft 421 to drive the spring spring to tighten, that is, after the pressing adjustment component 3 completes the pressing setting, the spring spring is tightened; when the spring spring recovers, it drives the driven gear 44 and the external threaded column 31 to rotate in the opposite direction, thereby resetting the movable sleeve 32;

[0058] The timing is set by using the operating button at the side end of the fixed plate 1. When the timing is turned on, the control module controls all electromagnetic telescopic columns 6 to turn on, and the magnetic slide column 62 extends in. Since the magnetic slide column 62 at the side end of the movable sleeve 32 is provided with a damping block, a plurality of magnetic slide columns 62 that are blocked by the movable sleeve 32 and not extended hold the movable sleeve 32 tightly and fix it, thereby limiting the movable sleeve 32 and making it difficult for the movable sleeve 32 to reset;

[0059] After the timing setting is completed, the timing module starts the countdown. After the countdown ends, the control module cuts off the power to the electromagnetic telescopic column 6; then the magnetic slide column 62 shrinks and resets, at which time the limit of the movable sleeve 32 is released, and the movable sleeve 32 is reset under the action of the clockwork spring;

[0060] This solution facilitates pressure adjustment and can automatically reset and reduce pressure after the countdown, so that medical staff do not need to provide real-time care. It is also easy to disassemble and store to meet different compression needs.

[0061] The third implementation method:

[0062] Figure 3 - Figure 5 It is shown that the control module is provided with a graded decompression mode and a full decompression mode; both the full decompression mode and the graded decompression mode can be selected when the lower rotating shaft 43 is docked with the docking rotating shaft 421, and a push switch is installed at the top of the lower rotating shaft 43; after the push switch is triggered, the graded decompression mode and the full decompression mode can be selected;

[0063] In the graded decompression mode, the electromagnetic telescopic columns 6 located on the upper side of the movable sleeve 32 are all opened and extended. When the movable sleeve 32 is reset to the position of the limit group, the communication module sends a message to the wirelessly connected user end whether to confirm the decompression. After the user end confirms the decompression (the user end can send a confirmation signal to the communication module to confirm the decompression or use the operation button to confirm the decompression), the control module controls the corresponding electromagnetic telescopic column 6 to cut off the power, so that the magnetic slide column 62 shrinks, and the movable sleeve 32 continues to reset. Repeat the above steps until the movable sleeve 32 is completely reset;

[0064] Optionally, the graded decompression mode can also be set as follows: each time the movable sleeve 32 is reset to a limit group, the timing module starts the timing setting time. After the timing is completed, the electromagnetic telescopic column 6 at this position is powered off, and the movable sleeve 32 continues to reset. The above steps are repeated until the movable sleeve 32 is completely reset, and the pressure is completely reduced.

[0065] In the full decompression mode, when the timing module counts to the set time, all electromagnetic telescopic columns 6 are powered off, the magnetic slide columns 62 are all retracted into the limit slide grooves, and the movable sleeve 32 is gradually fully reset under the action of the reset spring assembly 4.

[0066] This solution realizes flexible switching between the graded decompression mode and the comprehensive decompression mode to adapt to different medical scenarios and patient needs. In the graded decompression mode, by controlling the orderly power-off of the electromagnetic telescopic column 6, the movable sleeve 32 is reset in stages, which facilitates the gradual release of pressure by the pressing block 34, thereby avoiding the problem of blood reflux caused by sudden decompression. This mode is particularly suitable for patients who need slow decompression to ensure their safety and comfort. The comprehensive decompression mode is suitable for emergency situations or specific medical procedures, such as rapid hemostasis after surgery. In this mode, the movable sleeve 32 will quickly complete the reset after the set time, thereby achieving rapid decompression. This mode can effectively reduce the time for hemostasis and improve medical efficiency.

[0067] This solution also has an intelligent monitoring function. The monitoring module can collect data from the pressure sensor in real time and provide accurate compression pressure information to medical staff through the display screen. This helps medical staff to adjust the compression force in time to ensure the hemostasis effect.

[0068] In actual applications, medical staff can connect to the patient's end device through the wireless communication module, monitor the patient's condition in real time, and remotely adjust the decompression mode as needed. This remote control function greatly improves the flexibility and convenience of medical operations.

[0069] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
