[0002] In the field of medical care, compression hemostasis for arterial bleeding has always been an important operation. Traditional compression hemostasis methods often rely on the experience and manual operation of medical staff, lacking precise positioning and pressure control. For example, when using ordinary compression tools or relying solely on manual compression, it is difficult to ensure that the compression position is accurately aligned with the artery, which can easily lead to hemostasis failure or delay, posing risks to the patient's health.

[0003] Moreover, the traditional method lacks a precise adjustment mechanism for adjusting the pressure. Medical staff cannot accurately control the pressure and depth according to individual differences of patients, such as the thickness of blood vessels and the severity of bleeding. Excessive pressure may cause unnecessary damage to surrounding tissues, while insufficient pressure will lead to incomplete hemostasis. These problems often occur in the actual medical care process.

The stable sliding of the guide block in the long guide groove not only provides precise guidance for the movement of the core functional shell, but also allows the pressing pad to flexibly adjust its position according to actual needs, thereby ensuring precise pressure on the arterial blood vessels, greatly improving the success rate and effect of hemostasis, and effectively reducing the failure or delay of hemostasis caused by inaccurate pressing position.

[0031] Comfort and safety: The design of the adjustable strap fully considers the patient's comfort and the stability of the device. By fixing its two ends on the side connection ears and flexibly adjusting them according to the actual situation of the patient's limbs, it can ensure that the device is firmly fixed on the limbs during use to prevent displacement from affecting the hemostasis effect, and avoid unnecessary pressure and discomfort on the patient's limbs due to excessive binding, effectively improving the patient's comfort and tolerance during the hemostasis process, and helping patients to better cooperate with treatment.

[0032] The structural design of the annular connecting plate, especially the arc-shaped elastic plate and rubber ring on the lower side of the transverse part, significantly improves the patient's experience while ensuring the pressing effect. The arc-shaped elastic plate can better fit the curve of the limb, evenly disperse the pressure, and reduce the local pressure concentration point; the rubber ring further increases the softness and friction of the contact with the skin, preventing the pressing pad from sliding during use, thereby improving the stability and comfort of the pressing, and reducing the pain and discomfort of the patient during the hemostasis process.

[0033] Pressure visualization and controllability: The electrical connection between the pressure display and the annular pressure sensor provides medical staff with intuitive and real-time pressure data. During the entire hemostasis process, medical staff can accurately understand the pressure of the pressing part at any time according to the value on the pressure display, so as to adjust the operation of the handle screw in a timely and accurate manner to achieve precise control of the pressing pressure. This visual pressure monitoring system not only improves the safety of the operation, but also makes the hemostasis process more scientific and standardized, greatly reducing the risk of complications caused by improper pressure, such as local tissue ischemia and congestion.

The pressure display 37 and the battery 38 are electrically connected, and the pressure display 37 and the annular pressure sensor 23 are electrically connected.

[0055] It also includes an adjustable strap 39 , both ends of which are fixed on the side connecting ears 3 .

[0056] Device preparation and initial fixation:

[0057] The medical staff first fixes the two ends of the adjustable restraint belt 39 to the side connecting ears 3 on both sides of the upper annular frame 2 of the core pressing mechanism 1 to ensure a firm connection.

[0058] Place the device next to the limb part of the patient that needs to stop bleeding, adjust the position so that the annular outer elastic pressing pad 27 and the inner elastic pressing pad 28 of the annular connecting plate body 24 are roughly aligned above the patient's arterial blood vessels. At this time, attention should be paid to the appropriate direction and position of the upper annular frame 2 so that subsequent operations can proceed smoothly.

[0059] Fixation of the device on the limb:

[0060] Pick up the adjustable strap 39, wrap it around the patient's limbs, and appropriately adjust the tightness of the strap according to the thickness of the patient's limbs and actual conditions so that the device can be firmly fixed on the limbs. At the same time, ensure the patient's comfort and avoid unnecessary pressure on the limbs due to excessive tightness.

[0061] Initial adjustment of the core pressing mechanism:

[0062] The medical staff gently presses the upper pressing pad 36 on the handle 35 of the core pressing mechanism 1 to make it move initially in the space formed by the upper annular frame 2 and the sliding track 4. At this time, the guide block 13 on the outer wall 9 of the core function housing 8 will slide in the long guide groove 5 on the inner side of the sliding track 4, playing a guiding role, ensuring that the core function housing 8 moves smoothly and in the right direction, and at the same time, you can also feel the smoothness of the movement and the coordination between the various components.

[0063] During the movement, pay attention to the relative position relationship between the entire core functional shell 8 and the annular outer elastic pressing pad 27 and the inner elastic pressing pad 28 and the patient's limb arteries, and roughly adjust them to the appropriate height to prepare for subsequent precise pressing.

[0064] Fitting operation of the annular outer elastic pressure pad:

[0065] The user places a finger on the upper pressing pad 36 on the upper part of the handle portion 35 of the handle screw 32 and gently presses downward. During the pressing process, the core function housing 8 gradually moves downward in the space formed by the upper annular frame 2 and the sliding track 4, and the guide block 13 continues to slide in the long guide groove 5 to ensure the stability of the moving direction.

[0066] As the core function shell 8 moves downward, the annular outer elastic pressure pad 27 of the annular connecting plate body 24 will gradually approach and stick to the artery of the patient's limb. When you feel that the annular outer elastic pressure pad 27 is in contact with the skin and has a certain degree of fit, stop pressing. At this time, you should ensure that the annular outer elastic pressure pad 27 can cover the surrounding area of ​​the artery and contact the skin evenly to avoid excessive or insufficient local pressure. When observed or with the help of other detection means, such as the value change of the pressure display 37. The limiting tooth 12 is embedded in the limiting tooth groove 6 provided in the long guide groove 5 to play a limiting role.

[0067] Precise compression with inner elastic compression pad:

[0068] The user holds the core function housing 8 with one hand to prevent it from moving, and holds the handle portion 35 of the handle screw 32 with the other hand, and slowly rotates the handle portion 35. As the handle portion 35 rotates, the stud portion 33 of the handle screw 32 rotates in the nut 31 and moves downward, because a pressing block 34 is provided at the lower part of the stud portion 33, and the pressing block 34 abuts against the upper middle part of the inner elastic pressing pad 28, so the pressing block 34 pushes the middle part of the inner elastic pressing pad 28 to bulge downward as the stud portion 33 moves downward.

[0069] In the process of rotating the handle 35, the protrusion degree of the inner elastic pressing pad 28 and the pressing effect on the artery should be closely observed. At the same time, since the stud part 33 of the handle screw 32 penetrates the tension spring 16 and the middle part of the traction plate 14, and the lower part of the tension spring 16 abuts against the middle part of the lower wall 17 of the core function shell 8, and the pulling auxiliary frame 18 is fixed on the upper side of the middle part of the traction plate 14, when the stud part 33 moves, it will have a certain impact on these components, but will not affect the overall pressing operation. After confirming that the inner elastic pressing pad 28 has accurately and effectively pressed the artery of the patient's limb, stop rotating the handle 35.

[0070] Pressure monitoring and adjustment:

[0071] During the process of pressing to stop bleeding, the annular pressure sensor 23 at the lower edge of the upper wall 19 of the core functional housing 8 monitors the pressure of the pressing part in real time. The annular pressure sensor 23 converts the pressure signal into an electrical signal and transmits it to the pressure display 37 electrically connected thereto.

[0072] Medical staff can observe the pressure value displayed on the pressure display 37 at any time, and judge whether the current pressing pressure is appropriate according to actual needs and the specific conditions of the patient. If the pressure is too high, it may cause damage to the patient's limbs. At this time, the handle portion 35 of the handle screw 32 can be appropriately rotated in the opposite direction to reduce the pressure of the pressing block 34 on the inner elastic pressing pad 28, thereby reducing the pressing pressure; if the pressure is too low and the hemostasis effect cannot be achieved, the handle portion 35 can be slowly rotated to increase the pressing pressure until the pressure value displayed on the pressure display 37 is within an appropriate range, ensuring the hemostasis effect while ensuring the safety and comfort of the patient.

[0073] Device removal after hemostasis procedure:

[0074] When the hemostasis operation is completed, the medical staff needs to remove the device from the patient's limb. First, hold the auxiliary pull frame 18 with one hand and slowly pull it upward. As the auxiliary pull frame 18 moves upward, the traction plate 14 will be driven to move upward, and the ends of the side wing plates 15 on the traction plate 14 are fixedly connected to the lower inner side of the vertical elastic plate body 11, so the vertical elastic plate body 11 will be deformed, and the auxiliary spring 22 will also be deformed and compressed due to the tension.

[0075] In this process, the limiting teeth 12 at the lower outer part of the vertical elastic plate body 11 will gradually disengage from the limiting tooth groove 6 provided in the long guide groove 5. When the limiting teeth 12 are completely disengaged from the limiting tooth groove 6, the pulling auxiliary frame 18 is continuously pulled, and the core function housing 8 can move outward relatively freely in the space formed by the upper annular frame 2 and the sliding track 4, driving the lower part of the annular outer elastic pressing pad 27 of the annular connecting plate body 24 and the inner elastic pressing pad 28 to gradually disengage from the artery of the patient's limb.

[0076] Finally, the connection between the adjustable strap 39 and the side connecting ear 3 is untied, and the device is removed from the patient's limb to complete the entire use process.

[0077] Cleaning and maintenance of the device:

[0078] In order to ensure the hygiene and performance of the device when it is used next time, the device needs to be cleaned after use. Since the outer side of the vertical portion 25 of the annular connecting plate body 24 and the inner side of the annular pressure sensor 23 are fixedly connected by threaded connection, the annular connecting plate body 24 can be easily removed from the core function housing 8.

[0079] The disassembled annular connecting plate body 24, the annular outer elastic pressing pad 27, the inner elastic pressing pad 28 and other parts are cleaned and disinfected with appropriate detergents and disinfection tools to remove the contaminants such as blood, stains and bacteria remaining thereon. After cleaning, air dry the parts or wipe them with a clean towel, and then reinstall the annular connecting plate body 24 on the core function housing 8 according to the correct installation method to ensure that the parts are firmly connected and ready for the next use. At the same time, other parts of the device can also be visually inspected and simply cleaned, such as the upper annular frame 2, the sliding track 4, the core function housing 8, etc., to ensure the overall integrity and good performance of the device.

[0080] Through the above detailed specific implementation methods and usage steps, the function of the nursing compression hemostasis device can be fully utilized to effectively perform compression hemostasis operations on the patient's limbs, while ensuring the accuracy, safety and comfort of the operation, and facilitating the cleaning and maintenance of the device, providing convenience for the work of medical staff.

[0081] Precise positioning and pressure: The ingenious design of the upper annular frame 2, the sliding track 4 and the core functional shell 8 in the core pressing mechanism 1 ensures that the annular outer elastic pressing pad 27 and the inner elastic pressing pad 28 can be accurately aligned with the patient's arterial blood vessels. The stable sliding of the guide block 13 in the long guide groove 5 not only provides precise guidance for the movement of the core functional shell 8, but also allows the pressing pad to flexibly adjust its position according to actual needs, thereby ensuring accurate pressure on the arterial blood vessels, greatly improving the success rate and effect of hemostasis, and effectively reducing the failure or delay of hemostasis caused by inaccurate pressing position.

[0082] The inner elastic pressing pad 28 can achieve precise central pressing of the artery through fine adjustment of the handle screw 32. The screw thread of the stud part 33 of the handle screw 32 cooperates with the nut 31, and the pressing block 34 precisely acts on the inner elastic pressing pad 28, so that medical staff can accurately control the pressing force and depth according to the patient's specific conditions, such as the thickness of the blood vessels, the degree of bleeding, etc., to avoid excessive pressure causing damage to surrounding tissues, and also prevent the problem of incomplete hemostasis caused by insufficient pressure.

[0083] Comfort and safety: The design of the adjustable strap 39 fully considers the comfort of the patient and the stability of the device. By fixing its two ends on the side connecting ears 3 and flexibly adjusting it according to the actual situation of the patient's limbs, it can ensure that the device is firmly fixed on the limbs during use to prevent displacement from affecting the hemostasis effect, and avoid unnecessary pressure and discomfort on the patient's limbs due to over-tightening, effectively improving the patient's comfort and tolerance during the hemostasis process, and helping the patient to better cooperate with the treatment.

[0084] The structural design of the annular connecting plate 24, especially the arc-shaped elastic plate 30 and the rubber ring 29 on the lower side of the transverse portion 26, significantly improves the patient's experience while ensuring the pressing effect. The arc-shaped elastic plate 30 can better fit the curve of the limb, evenly disperse the pressure, and reduce the local pressure concentration point; the rubber ring 29 further increases the softness and friction of contact with the skin, preventing the pressing pad from sliding during use, thereby improving the stability and comfort of pressing, and reducing the pain and discomfort of the patient during the hemostasis process.

[0085] Pressure visualization and controllability: The electrical connection between the pressure display 37 and the annular pressure sensor 23 provides medical staff with intuitive and real-time pressure data. During the entire hemostasis process, medical staff can accurately understand the pressure of the pressing part at any time according to the value on the pressure display 37, so as to timely and accurately adjust the operation of the handle screw 32 to achieve precise control of the pressing pressure. This visual pressure monitoring system not only improves the safety of the operation, but also makes the hemostasis process more scientific and standardized, greatly reducing the risk of complications caused by improper pressure, such as local tissue ischemia, congestion, etc.

[0086] Convenience of cleaning and maintenance: The threaded connection between the annular connecting plate 24 and the annular pressure sensor 23 provides great convenience for cleaning and maintenance of the device. After use, medical staff can easily disassemble the annular connecting plate 24 and its attached pressure pad for comprehensive and thorough cleaning and disinfection, effectively removing residual blood, stains and bacteria, ensuring that the sanitary condition of the device meets medical standards and reducing the risk of cross infection. At the same time, this easy-to-disassemble design is also conducive to regular inspection and maintenance of various components, timely detection and replacement of parts that may be worn or damaged, extending the service life of the device and improving the reliability and economy of the equipment.

[0087] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
