Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent compression hemostat for puncture points based on unmanned treatment. Background Technology

[0002] After the puncture, it is generally necessary to stop the bleeding at the puncture site. The traditional method of hemostasis is for the patient to use the non-puncture side hand to press directly on the gauze covering the puncture site to apply pressure for hemostasis. This process usually needs to last for about 20 minutes to achieve effective hemostasis. For patients with coagulation disorders, the pressure application time may need to be extended depending on the situation.

[0003] Patent CN214907541U discloses a pressure-based hemostasis device for radial artery puncture sites, including an upper clamp and a lower clamp. A round rod is disposed between one end of the upper clamp and one end of the lower clamp, and the upper and lower clamps are movably connected by the round rod. A torsion spring is disposed on one side of the round rod, and the top and bottom ends of the torsion spring are fixedly connected to the upper and lower clamps, respectively. By incorporating a rotating rod and a clamping plate, compared with the prior art, the rotating rod is threadedly connected to the fixed block, allowing the bottom pressure plate to move downwards or upwards to adjust the pressure force. Then, the clamping plate is merged with the upper clamp, causing the sleeve to move upwards through the threaded rod, further adjusting the pressure force.

[0004] The aforementioned patents all rely on manual pressure control for hemostasis after puncture. Manual pressure control cannot precisely meet the needs of wound healing, thus affecting the patient's wound healing effect. Therefore, they do not meet the existing requirements. In response, we have proposed an intelligent compression hemostasis device for puncture points based on unmanned treatment. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent compression hemostat for puncture points based on unmanned treatment. This device allows for adjustment of the position of the hemostat components, enabling precise positioning of the puncture point and ensuring accurate compression hemostasis. It determines whether the compression pressure of the compression block is too high or too low based on the amount of bleeding at the puncture point captured by a high-definition camera. Based on this determination, a pressure sensor is set to detect the pressure of the compression block. When the pressure sensor detects that the pressure of the compression block has reached the set pressure, the lifting component stops working, achieving intelligent compression hemostasis at the puncture point without manual operation. This makes it more convenient to use and improves hemostasis efficiency, thus solving the problems mentioned in the background art.

[0015] The high-definition camera transmits the captured photos of the puncture point location to the control unit in real time. The control unit is equipped with an image processing module, which is used to preprocess the collected photos of the puncture point location. By performing grayscale processing, noise reduction processing, and edge enhancement processing on the photos of the puncture point location, the difference between the bleeding area of ​​the puncture point and the surrounding skin is highlighted, forming a processed image of the bleeding area of ​​the puncture point.

[0016] A semantic segmentation model is constructed. The processed image of the bleeding area at the puncture point is input into the semantic segmentation model, and the bleeding area in the image of the bleeding area at the puncture point is segmented. The pixel area of ​​the bleeding area is calculated and converted into the physical area S of the bleeding area by combining the camera calibration parameters.

[0017] Based on the correspondence between bleeding volume, blood area, and blood thickness in clinical statistics, a preset empirical value for blood thickness is obtained.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention utilizes a movable component to allow the hemostatic component to move back and forth, enabling position adjustment. Connecting rods on both sides of the lead screw ensure the stability of the moving block's movement. A rotating component drives an adjusting component, which in turn adjusts the position of the moving plate, thereby adjusting the position of the hemostatic component to locate the puncture point and ensure accurate compression hemostasis. When the compression block contacts the puncture point, it continues to move downwards, applying pressure under spring compression. The pressure is determined based on the amount of bleeding at the puncture point captured by a high-definition camera; higher bleeding requires higher pressure, and lower bleeding requires lower pressure. A pressure sensor detects the pressure of the compression block based on this determination. When the pressure sensor detects that the pressure has reached the set level, the lifting component stops operating, achieving intelligent compression hemostasis at the puncture point without manual operation. This makes it more convenient and efficient, ensuring better wound healing for the patient. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To address the issue that existing technologies rely on manual pressure control of hemostatic devices after puncture, which cannot precisely regulate pressure to meet wound healing needs and thus negatively impact patient wound healing outcomes, please refer to [the relevant documentation / reference]. Figures 1-9 This embodiment provides the following technical solution:

[0034] The intelligent compression hemostat for puncture points based on unmanned treatment includes a main board 1, a display screen 2, and straps 3. The display screen 2 is installed on the upper surface of the main board 1, and straps 3 are fixed on both sides of the lower surface of the main board 1. A moving component 4 is installed on the lower surface of the main board 1, a driving component 5 is installed on the moving component 4, and a hemostatic component 6 is installed on the driving component 5.

[0035] The movable component 4 includes a connecting rod 41, a movable block 42, a lead screw 43, a first motor 44, and a mounting plate 45. The connecting rod 41 is located on both sides of the lead screw 43, and one end of the connecting rod 41 and the lead screw 43 is fixedly mounted on the lower surface of the main board 1, while the other end is mounted on the mounting plate 45. The mounting plate 45 is fixed to the lower surface of the main board 1, and the first motor 44 is mounted on the outer side of the mounting plate 45. The output end of the first motor 44 passes through the mounting plate 45 and is connected to the lead screw 43. The movable block 42 is movably mounted on the connecting rod 41 and the lead screw 43. By starting the first motor 44, the lead screw 43 rotates, thereby driving the movable block 42 to move back and forth along the lead screw 43 and the connecting rod 41, thereby enabling the hemostatic component 6 to move back and forth and adjust the position of the hemostatic component 6. The connecting rod 41 is located on both sides of the lead screw 43 to ensure the stability of the movement of the movable block 42.

[0036] The drive assembly 5 includes a mounting frame 51, a rotating assembly 52, a moving plate 53, and an adjusting assembly 54. The mounting frame 51 is fixedly mounted on the moving block 42. The rotating assembly 52 is used to drive the adjusting assembly 54. The adjusting assembly 54 is used to adjust the position of the moving plate 53, thereby adjusting the position of the hemostasis assembly 6, locating the puncture point, and ensuring the accuracy of the compression hemostasis position. The rotating assembly 52 is installed inside the mounting frame 51. The rotating assembly 52 passes through the mounting frame 51 and is connected to the adjusting assembly 54. The adjusting assembly 54 is rotatably mounted on the moving plate 53.

[0037] The rotating assembly 52 includes a second motor 521, a first driving gear 522, and a first driven gear 523. The output end of the second motor 521 is connected to the first driving gear 522. The first driving gear 522 meshes with the first driven gear 523. By starting the second motor 521, the first driving gear 522 is rotated, which in turn drives the first driven gear 523 meshing with the first driving gear 522 to rotate.

[0038] The adjustment assembly 54 includes a second driving gear 541, a driving shaft 542, a rotating shaft 543, a third driven gear 544, a second driven gear 545, and a driven shaft 546. The driving shaft 542 is fixedly mounted on the second driving gear 541. The second driving gear 541 meshes with the third driven gear 544. The third driven gear 544 is fixed on the rotating shaft 543. The end of the third driven gear 544 away from the second driving gear 541 meshes with the second driven gear 545. The second driven gear 545 is fixedly mounted on the driven shaft 546.

[0039] One end of the drive shaft 542 away from the second drive gear 541 is fixed to the first drive gear 522. The rotating shaft 543 is rotatably mounted on the movable plate 53. One end of the driven shaft 546 away from the second driven gear 545 is fixed to the first driven gear 523. The second drive gear 541 and the second driven gear 545 are half-gear structures, and their directions of movement are opposite. The second drive gear 541 drives the third driven gear 544 to rotate clockwise, and the second driven gear 545 drives the third driven gear 544 to rotate counterclockwise. Therefore, the rotating shaft 543 rotates 180° clockwise and then immediately rotates 180° counterclockwise. This starts the second motor 521, causing the drive shaft 542 to rotate, which in turn drives the first drive gear 522 and the second drive gear 541 to rotate. The rotation of the first drive gear 522 drives the first driven gear 523 to rotate, which in turn drives the driven shaft 546 and the second driven gear 545. The rotation of the second driving gear 541 and the second driven gear 545 drives the third driven gear 544 to move left and right, thereby enabling the high-definition camera 613 to capture images around the puncture point and accurately locate the puncture point. When the location of the puncture point is determined, the third motor 611 is started to rotate the connecting shaft 614, rotating the rotating base plate 612 to a position away from the installation sleeve 63. Then, the fourth motor 651 is started to rotate the threaded rod 652, causing the compression component 62 to move downward and the compression block 625 to the puncture point for intelligent compression hemostasis. The compression block 625 is equipped with a pressure sensor to monitor the pressure of the compression block 625. When the pressure exceeds the set pressure value, the fourth motor 651 reverses, driving the compression block 625 to move upward until the compression block 625 reaches the set pressure value. This enables real-time monitoring and adjustment of the hemostasis pressure, ensuring the effectiveness of compression hemostasis.

[0040] The hemostatic assembly 6 includes a base plate assembly 61, a compression assembly 62, an installation sleeve 63, an installation groove 64, and a lifting assembly 65. The base plate assembly 61 is located at the bottom of the installation sleeve 63. The installation sleeve 63 has installation grooves 64 on both sides inside. The lifting assembly 65 is located in the installation groove 64. The compression assembly 62 is movably mounted on the lifting assembly 65.

[0041] The base plate assembly 61 includes a third motor 611, a rotating base plate 612, a high-definition camera 613, and a connecting shaft 614. The output end of the third motor 611 is connected to the connecting shaft 614. The connecting shaft 614 passes through the rotating base plate 612 and is rotatably mounted on the mounting sleeve 63. The high-definition camera 613 is located at the center of the rotating base plate 612. The high-definition camera 613 is used to acquire images of the puncture site, thereby determining the specific location of the puncture point. This allows the compression assembly 62 to accurately compress and stop bleeding at the puncture point without manual operation, ensuring the efficiency and accuracy of compression hemostasis.

[0042] The compression assembly 62 includes an outer sleeve 621, a spring 622, a slot 623, an inner sleeve 624, a compression block 625, and a locking block 626. Slots 623 are formed on the inner walls of both sides of the outer sleeve 621. A locking block 626 is movably installed within each slot 623 and is fixed to the inner sleeve 624. The inner sleeve 624 and the outer sleeve 621 are connected by the spring 622. A connecting block 627 is fixedly installed at the bottom of the inner sleeve 624. A compression block 625 is located at the bottom of the connecting block 627, and a pressure sensor is installed on the compression block 625. The spring 622 provides the compression block 625 with a certain elasticity, thereby enabling... The device compresses the puncture site to stop bleeding and adjusts the position of the compression block 625 via the lifting assembly 65. When the compression block 625 contacts the puncture site, it continues to be adjusted downwards. Under the compression of the spring 622, the compression block 625 has a certain pressure. The compression pressure of the compression block 625 is judged based on the amount of bleeding at the puncture site captured by the high-definition camera 613. If the amount of bleeding is large, the pressure is large; if the amount of bleeding is small, the pressure is small. Based on the judgment result, a pressure sensor is set to sense the pressure of the compression block 625. When the pressure sensor senses that the pressure of the compression block 625 has reached the set pressure, the lifting assembly 65 stops working.

[0043] Specifically, in order to control the compression pressure of the compression block 625, the technical solution of this application also includes a control unit. The control unit is electrically connected to the high-definition camera 613, the lifting assembly, and the pressure sensor, and controls the pressure of the puncture point for hemostasis through the following steps:

[0044] The high-definition camera 613 transmits the captured images of the puncture point location to the control unit in real time. The control unit is equipped with an image processing module for preprocessing the captured images of the puncture point location. By performing grayscale processing, noise reduction processing, and edge enhancement processing on the images of the puncture point location, the difference between the bleeding area at the puncture point and the surrounding skin is highlighted, forming a processed image of the bleeding area at the puncture point. The processed image of the bleeding area at the puncture point can clearly define the location and shape of the bleeding area. The high-definition camera 613 can be a medical-grade CCD / CMOS camera to improve the clarity of the captured images. The high-definition camera is installed at an appropriate height above the puncture area to ensure that the shooting angle is vertically aligned with the puncture point and that the lighting is uniform without obvious shadows.

[0045] A semantic segmentation model is constructed. The processed image of the bleeding area at the puncture point is input into the semantic segmentation model, which segments the bleeding region in the image. The pixel area of ​​the bleeding region is calculated and converted into the physical area S of the bleeding region based on camera calibration parameters. The semantic segmentation model adopts the UNet model or other deep learning models. The UNet model is a neural network model for medical image segmentation. It captures contextual information and accurately locates the bleeding region by using shrinking and expanding paths. By training on a labeled medical image dataset of 'bleeding region-skin background', the semantic segmentation model can accurately segment the bleeding region of the puncture point in the image. The output can be a binary segmentation map, with the bleeding region outputting 1 and the skin background outputting 0. The camera calibration parameters, such as camera focal length and object distance, can be converted into the physical area S of the bleeding region based on the pixel area of ​​the bleeding region using perspective transformation formulas.

[0046] Based on the correlation between bleeding volume, blood area, and blood thickness obtained from clinical statistics, a preset empirical value for blood thickness is obtained. The bleeding physical area S is multiplied by the empirical value for blood thickness to calculate the estimated bleeding volume at the puncture point. The correlation between bleeding volume, blood area, and blood thickness can be determined by combining a large amount of clinical data, because the location of the puncture point and the bleeding volume under normal circumstances are within the analyzable range in clinical practice. Through statistical principles, the bleeding volume, blood area, and blood thickness after each puncture are recorded, and after summarizing, an approximate correlation between bleeding volume, blood area, and blood thickness can be obtained. Therefore, based on the previously obtained bleeding physical area S, the empirical value for blood thickness can be derived, thereby further obtaining the estimated bleeding volume.

[0047] Based on the correlation between blood loss and effective compression force established through clinical statistics, the effective compression force is obtained by estimating the blood loss at the puncture point. The control unit then controls the lifting assembly to move the compression block 625 to compress the puncture point based on the obtained effective compression force. When the pressure sensor detects that the pressure value has reached the effective compression force, the lifting assembly stops compressing. The mapping relationship between blood loss and effective compression force can be obtained through in vitro simulation experiments or clinical trials. For example, in in vitro simulations, fresh blood and simulated skin are used. Under controlled conditions, a quantitative amount of blood is dripped to simulate different blood loss volumes. Different pressures are applied using a hemostat (pressure is recorded in real time by a pressure sensor), and the hemostatic effect is observed. The time of bleeding cessation and the amount of oozing are recorded, and the corresponding data of blood loss and effective compression force are recorded. After obtaining the estimated blood loss, the effective compression force can be obtained based on this correlation. Then, the control unit controls the movement of the lifting assembly, which moves the compression component 62, thereby moving the compression block 625 to compress the puncture point. The compression force is recorded in real time during the compression process. When the pressure sensor detects that the pressure value has reached the preset effective compression force, it indicates that the required compression purpose has been basically achieved, and compression is stopped at this point.

[0048] The above technical solution, through the comprehensive analysis of the control unit, can make a general judgment on the bleeding situation at the puncture point, and then adjust the squeezing force of the compression component accordingly. The pressure is higher for large bleeding and lower for small bleeding, which can target the puncture point and thus improve the hemostasis effect.

[0049] The lifting assembly 65 includes a fourth motor 651, a threaded rod 652, a slider 653, a slide bar 654, and a fixed rod 655. The output end of the fourth motor 651 is connected to the threaded rod 652. The threaded rod 652 is rotatably installed in one of the mounting slots 64, and the slide bar 654 is fixedly installed in the other mounting slot 64. The slide bar 654 and the threaded rod 652 are positioned correspondingly. The slider 653 is movably installed on both the slide bar 654 and the threaded rod 652. The fixed rod 655 is fixedly installed on the slider 653. The fixed rod 655 is fixedly installed on the outer sleeve 621. By starting the fourth motor 651, the threaded rod 652 is rotated, which causes the slider 653 to move along the slide bar 654 and the threaded rod 652, thereby moving the compression assembly 62 to the puncture point so that the compression assembly 62 can apply pressure to the puncture point to stop bleeding.

[0050] The extrusion block 625 is detachably connected to the connecting block 627 via a connecting assembly. The connecting assembly includes a mounting cavity within the connecting block 627. A mounting hole 661 is provided at the lower end of the connecting block 627, communicating with the mounting cavity. A connecting post 662 is provided within the mounting hole 661. The lower end of the connecting post 662 is fixedly connected to the upper surface of the extrusion block 625. The upper end of the connecting post 662 extends into the mounting cavity and is provided with a connecting head 663. The connecting head 663 is hemispherical, and its diameter is larger than the diameter of the connecting post 662. A sliding joint is provided on the sidewall of the connecting block 627. The moving hole and sliding hole communicate with the mounting cavity. A limiting plate 664 is slidably installed inside the sliding hole. The upper surface of the limiting plate 664 contacts the lower surface of the connector 663. One end of the limiting plate 664 extends to the outside of the connecting block 627 and is provided with a driving plate 666. A first return spring 665 is sleeved on the outside of the limiting plate 664. One end of the first return spring 665 is connected to the driving plate 666, and the other end of the first return spring 665 is connected to the outer wall of the connecting block 627. A positioning plate 667 is provided directly above the connecting post 662. The front and rear sides of the positioning plate 667 are aligned with the front and rear inner walls of the mounting cavity. The upper surface of the positioning plate 667 is connected to the top wall of the mounting cavity via several connecting springs 668. A positioning groove is provided on the lower surface of the positioning plate 667. The upper surface of the connector 663 contacts the inner wall of the positioning groove. Two clamping plates 669 are slidably arranged on the bottom wall of the mounting cavity, symmetrically positioned about the center of the connecting post 662. The bottom of the clamping plates 669 is slidably connected to the bottom wall of the mounting cavity. A second return spring 670 is provided on one side of each clamping plate 669 away from the clamping plate 669. The end of the second return spring 670 away from the clamping plate 669 is connected to the inner wall of the mounting cavity. The wall connection is provided with fixed pulleys 671 on the front and rear inner walls of the mounting cavity. The two fixed pulleys 671 are centrally symmetrical about the center of the connecting column 662. The clamping plate 669 is provided with through holes 672. The two through holes 672 are centrally symmetrical about the center of the connecting column 662. One end of the through hole 672 is aligned with the fixed pulley 671. A connecting rope 673 is slidably installed in the through hole 672. One end of the connecting rope 673 extends to the outside of the clamping plate 669 and is connected to the side wall of the other clamping plate 669. The other end of the connecting rope 673 passes around the fixed pulley 671 and is connected to the positioning plate 667.

[0051] Initially, the upper surface of the limiting plate 664 contacts the lower surface of the connector 663, while the end of the limiting plate 664 contacts the connecting post 662. The upper surface of the connector 663 contacts the inner wall of the positioning groove of the positioning plate 667. Under the joint clamping of the two clamping plates 669, the connecting post 662 is stably held in the center position of the mounting hole 661, thereby causing the upper surface of the extrusion block 625 to contact the lower surface of the connecting block 627. The extrusion block 625 is stably connected to the connecting block 627 through the connecting assembly, allowing the extrusion block 625 to stably compress the hemostatic position and improve the hemostatic effect. After hemostasis is completed, in order to facilitate the cleaning of the extrusion block 625, the extrusion block 625 is... 25 is detachably connected to the connecting block 627 via the connecting assembly. Pulling the drive plate 666 outward can cause the limiting plate 664 to slide outward, compressing the first return spring 665. Under the action of the connecting spring 668, the positioning plate 667 slides downward and pushes the connector 663 to move outward from the connecting block 627. Under the action of the second return spring 670, the two clamping plates 669 move away from the connecting post 662. Then, the connecting post 662 and the connector 663 can be removed from the mounting hole 661, thereby disinfecting and sterilizing the extrusion block 625, improving the cleanliness of the extrusion block 625, and facilitating its next hemostasis use. Block 625 prevents infection at the user's puncture site, improving safety. To install the compression block 625, simply insert the connector 663 upwards into the mounting hole 661, then push the compression block 625 upwards. The compression block 625, through the connecting post 662, drives the connector 663 upwards. After contacting the limiting plate 664, the connector 663 first pushes the limiting plate 664 outwards via its curved surface. Once the connector 663 passes the limiting plate 664, under the elastic force of the first return spring 665, the limiting plate 664 slides to the lower surface of the connector 663. Simultaneously, during the upward movement of the connector 663, the connector 663 is positioned on the positioning plate 667. Within the positioning groove, the connector 663 is prevented from wobbling left and right. The connector 663 can drive the positioning plate 667 to slide upward. The positioning plate 667 can pull the clamping plate 669 to slide closer to the connecting post 662 via the connecting rope 673. When the limiting plate 664 contacts the lower surface of the connector 663, both clamping plates 669 are in contact with the connecting post 662, thereby preventing the connecting post 662 from wobbling within the mounting hole 661. This improves the stability of the compression block 625, thereby enabling stable compression and hemostasis at the puncture point and improving the hemostasis effect. By setting the connecting component, the disassembly and assembly speed of the compression block 625 can also be improved, facilitating the periodic replacement of the compression block 625.

[0052] Working principle: When using the intelligent compression hemostat for puncture points based on unmanned treatment of this invention, according to... Figures 1-9 This includes the following steps:

[0053] Step 1: Use the strap 3 to fix the intelligent compression hemostat at the puncture site of the patient, and then start the first motor 44 to make the lead screw 43 rotate, which in turn drives the moving block 42 to move back and forth along the lead screw 43 and the connecting rod 41, thereby enabling the hemostatic component 6 to move back and forth to adjust the position of the hemostatic component 6.

[0054] Step 2: Simultaneously start the second motor 521 to rotate the drive shaft 542, which drives the first drive gear 522 and the second drive gear 541 to rotate. The rotation of the first drive gear 522 drives the first driven gear 523 to rotate, which in turn drives the driven shaft 546 and the second driven gear 545 to rotate. The rotation of the second drive gear 541 and the second driven gear 545 drives the third driven gear 544 to move left and right, which in turn enables the high-definition camera 613 to capture images around the puncture point.

[0055] Step 3: When the location of the puncture point is determined, start the third motor 611 to rotate the connecting shaft 614, rotate the rotating base plate 612 to a position away from the installation sleeve 63, and then start the fourth motor 651 to rotate the threaded rod 652, causing the compression component 62 to move downward, move the compression block 625 to the puncture point, and perform intelligent compression hemostasis on the puncture point.

[0056] Step 4: When the squeezing block 625 contacts the puncture point, continue to adjust the squeezing block 625 downwards. Under the compression of the spring 622, the squeezing block 625 has a certain pressure. Based on the amount of bleeding at the puncture point captured by the high-definition camera 613, determine whether the squeezing pressure of the squeezing block 625 is too high or too low. If the amount of bleeding is high, the pressure is high; if the amount of bleeding is low, the pressure is low. Based on the judgment result, set the pressure sensor to sense the pressure of the squeezing block 625. When the pressure sensor senses that the pressure of the squeezing block 625 has reached the set pressure, the lifting component 65 stops working.

[0057] Step 5: When the pressure exceeds the set pressure value, the fourth motor 651 reverses, driving the extrusion block 625 to move upward until the extrusion block 625 reaches the set pressure value.

[0058] In summary, the intelligent compression hemostat for puncture points based on unmanned treatment of the present invention, by activating the first motor 44, causes the lead screw 43 to rotate, thereby driving the moving block 42 to move back and forth along the lead screw 43 and the connecting rod 41, thus enabling the hemostasis component 6 to move back and forth, achieving adjustment of the position of the hemostasis component 6. The connecting rod 41 is set on both sides of the lead screw 43 to ensure the stability of the movement of the moving block 42. The set rotation component 52 is used to drive the adjustment component 54, which is used to adjust the position of the moving plate 53, thereby adjusting the position of the hemostasis component 6, locating the puncture point, and ensuring the accuracy of the compression hemostasis position. When the compression block 62 5. When in contact with the puncture point, continue to adjust the compression block 625 downwards. Under the compression of the spring 622, the compression block 625 has a certain pressure. Based on the amount of bleeding at the puncture point captured by the high-definition camera 613, determine whether the compression pressure of the compression block 625 is too high or too low. If the amount of bleeding is high, the pressure is high; if the amount of bleeding is low, the pressure is low. Based on the judgment result, the pressure sensor is set to sense the pressure of the compression block 625. When the pressure sensor senses that the pressure of the compression block 625 has reached the set pressure, the lifting component 65 stops working, realizing intelligent compression hemostasis at the puncture point without manual operation. It is more convenient to use and has higher hemostasis efficiency, ensuring the healing effect of the patient's wound.
