[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1

[0030] like Figure 3-5 As shown, the regulator includes an adjusting ring 101, a spring 104, an adjusting seat 102, and an adjusting rod 103; the adjusting ring 101 is symmetrically arranged inside the housing 1 and is slidably connected to the housing 1, a groove is arranged at the end of the adjusting ring 101, and the two ends of the groove are movably connected to the adjusting seat 102; a spring 104 is arranged in the middle of the adjusting seat 102, and an adjusting rod 103 is arranged on the adjusting seat 102; slide grooves 105 are respectively arranged on the housing 1 at positions corresponding to the adjusting rod 103; a plurality of card slots are arranged on both sides of the slide groove 105; the regulator is symmetrically arranged on both sides, a groove is opened in the middle of the adjusting ring 101 on one side and is slidably connected to the adjusting ring 101 on the other side, and a circular hole is formed at the intersection of the two adjusting rings 101;

[0031] In this embodiment, when the regulator is in use, the adjusting rod 103 is pressed to clamp the spring 104 between the two adjusting seats 102 and 102, and the adjusting rods 103 symmetrically arranged at both ends are pulled to slide along the slide groove 105. According to the size of the puncture site of the patient, the cross position of the two adjusting rings 101 is adjusted to a suitable size, and the adjusting rod 103 is released. Under the reset action of the spring 104, the adjusting seat 102 is pushed to both ends, thereby driving the adjusting rod 103 to be clamped into the clamping grooves at both ends of the slide groove 105, and the two adjusting rings 101 are fixed;

[0032] In this embodiment, the regulator can accurately control the area covered by the pressing device through the cooperation of the adjusting ring 101 and the adjusting rod 103, ensuring that only the puncture site is pressed to avoid unnecessary pressure on the surrounding tissues. By accurately controlling the shape and size of the memory foam 207, the regulator helps to improve the pressing effect and reduce the risk of postoperative bleeding and hematoma. Compared with the prior art, the present invention accurately controls the pressing range through the regulator, thereby solving the problem of poor pressing accuracy in the prior art. By providing uniform and appropriate pressing strength, the present invention helps to reduce postoperative complications and promote rapid recovery of patients.

[0033] Example 2

[0034] like Figure 1 , 2As shown, the adjuster is symmetrically arranged on both sides, a groove is provided in the middle of the adjusting ring 101 on one side and is slidably connected to the adjusting ring 101 on the other side, and a circular hole is formed at the intersection position between the two adjusting rings 101; the shell 1 is semicircular, a groove is provided in the middle of the shell 1, a cavity is provided at the inner ring position of the shell 1 to flexibly connect the adjuster, a circular hole is provided at the bottom of the groove, horizontal circular holes are provided on the two side walls of the groove, vertical circular holes are provided on the shell 1 on both sides of the groove, and the end of the shell 1 is rotatably connected to the tightening belt 3; the pressing device includes a pressing shell, a pressing head 206, a pressing rod 205, a pressing plate 204, and a memory foam 207; the pressing shell is flexibly connected to the groove of the shell 1, the bottom of the pressing shell corresponds to the center of the adjusting ring 101, and circular holes are provided on both sides and the top of the pressing shell , the top circular hole is threadedly connected to the pressing rod 205; a pressing head 206 is arranged on the top of the pressing rod 205, and a pressing plate 204 is arranged at the bottom; a memory foam 207 is arranged below the pressing plate 204; a clamping mechanism is symmetrically arranged on both sides of the pressing device; the clamping mechanism includes a knob 208, a gear 203, and a screw 202; the screw 202 is movably connected to the circular holes on both sides of the groove; the knob 208 is movably connected to the vertical circular hole of the shell 1, and a gear 203 is arranged at the lower end of the knob 208 to engage the screw 202; a hole is opened in the middle of the knob 208 and connected to the cavity at the inner ring of the shell 1, and a delivery port is arranged on the top of the knob 208; a soft patch 5 is arranged at the position of the circular hole inside the shell 1; a hemostatic pad 4 is arranged below the soft patch 5;

[0035] In this embodiment, when the device is in use, the hemostatic pad 4 is first pasted on the soft patch 5, and the device is fixed to the patient's pressing part by the tightening belt 3. Then, according to the range adjusted by the adjustment ring 101, the pressing device is inserted into the groove of the shell 1, and the knobs 208 at both ends are rotated to drive the gear 203 to rotate. The rotation of the gear 203 drives the meshing screw 202 to slide, and the screw 202 slides into the holes on both sides of the pressing shell to fix the pressing shell. After the fixing is completed, the pressing head 206 is rotated to drive the pressing rod 205 to rotate.

The locking mechanism fixes the pressing device in an appropriate position through the cooperation of the knob 208, the gear 203 and the screw 202 to ensure the stability of the pressing force. When the puncture site needs to be observed or treated, the locking mechanism allows the pressing device to be quickly disassembled, thereby improving the convenience of nursing. Compared with the prior art, the pressing mechanism 2 of the present invention provides a more accurate pressing range and force through the combination of the adjusting ring 101 and the memory foam 207, thereby solving the problem of poor pressing accuracy in the prior art.

[0037] In this embodiment, delivering cold air to the inner ring of the device through knob 208 can quickly reduce blood flow at the puncture site, help stop bleeding and reduce postoperative swelling, and the application of cold air can be used as an auxiliary treatment method to improve the patient's recovery quality; at the same time, the design of knob 208 cleverly integrates the functions of delivering cold air and fixing the pressing shell, which not only saves space but also improves the versatility of the device. The structural design of delivering cold air to the inner ring of the device through knob 208 not only improves the treatment effect and the patient's comfort, but also achieves multi-functional integration and ease of operation through clever mechanical design.

[0038] In summary, the present invention arranges an adjustment ring 101 at the inner ring of the housing 1, and pulls the adjustment rod 103 to move along the slide groove 105 on the housing 1, thereby controlling the size of the circular hole formed in the center of the adjustment ring 101, and can control the size and shape of the memory foam 207 connected thereto, so as to ensure that the pressing device can accurately align and press the puncture point, so as to achieve effective hemostasis;

[0039] At the same time, a pressing device is movably connected in the middle of the shell 1, and the clamping mechanism arranged on both sides of the groove of the shell 1 allows the screw 202 of the clamping mechanism to be inserted into the holes on both sides of the pressing shell, so as to limit and fix the pressing shell, so that the pressing mechanism 2 can be quickly removed when observation is needed after pressing the puncture site of the patient, and the hemostatic pad 4 can be pushed aside to observe the pressed site, and the knobs 208 on both sides of the pressing device can be used to deliver cold air to the inner ring of the device through the cavity in the center of the knob 208 to slow down the patient's blood flow rate, and in the later stage of recovery, gases of different temperatures can be delivered as needed to improve the patient's comfort.
