Description

Technical Field

[0001] The invention relates to compression hemostasis, in particular to a nursing compression hemostasis device. Background Art

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

[0003] Furthermore, traditional methods lack a precise adjustment mechanism for pressure. Medical staff are unable to accurately control the force and depth of compression based on individual patient differences, such as varying blood vessel thickness and bleeding severity. Excessive pressure can cause unnecessary damage to surrounding tissue, while insufficient pressure can lead to incomplete hemostasis. These problems often occur in real-world medical care.

[0004] In view of these current situations, it is necessary to develop a nursing compression hemostasis device that can accurately position and apply pressure. Summary of the Invention

The stable sliding of the guide block within the long guide groove not only provides precise guidance for the movement of the core functional housing, but also allows the pressing pad to be flexibly adjusted according to actual needs, thereby ensuring precise pressure on the arteries, greatly improving the success rate and effectiveness of hemostasis, and effectively reducing hemostasis failures or delays caused by inaccurate pressing positions.

[0030] The inner elastic pressure pad achieves precise, central compression of the artery through fine adjustment of the handle screw. The screw's stud engages the nut's threads, and the precise action of the pressure block on the inner elastic pressure pad allows medical staff to precisely control the force and depth of compression based on the patient's specific condition, such as vessel thickness and bleeding severity. This prevents excessive pressure that could damage surrounding tissue, while also preventing incomplete hemostasis due to insufficient pressure.

[0031] Comfort and safety are both important: The adjustable strap is designed with patient comfort and device stability in mind. By securing both ends to the side attachment ears and allowing for flexible adjustment based on the patient's limb's specific needs, the device is securely fastened to the limb during use, preventing displacement that could affect hemostasis. It also avoids unnecessary pressure and discomfort on the patient's limb due to overly tight restraints, effectively improving patient comfort and tolerance during hemostasis and helping them better cooperate with treatment.

[0032] The structural design of the annular connecting plate, particularly the curved elastic plate and rubber ring on the lower side of the transverse section, significantly enhances the patient experience while ensuring effective compression. The curved elastic plate better conforms to the curves of the limb, evenly distributing pressure and reducing localized pressure points. The rubber ring further increases the softness and friction of the contact pad with the skin, preventing it from slipping during use. This improves compression stability and comfort, reducing pain and discomfort during hemostasis.

[0033] Pressure Visualization and Controllability: The electrical connection between the pressure display and the annular pressure sensor provides medical staff with intuitive, real-time pressure data. Throughout the hemostasis process, medical staff can accurately monitor the pressure at the site of application based on the value displayed on the pressure display, enabling timely and accurate adjustment of the handle screw for precise control of compression pressure. This visual pressure monitoring system not only improves operational safety but also makes the hemostasis process more scientific and standardized, significantly reducing the risk of complications caused by improper pressure, such as localized tissue ischemia and congestion.

[0054] A pressure display 37 is fixed on the upper side of the upper wall 19 of the core function shell 8, and a battery 38 is fixed on the lower side of the upper wall 19 of the core function shell 8. 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] The device further comprises an adjustable strap 39 , both ends of which are fixed to the side connecting ears 3 .

[0056] Device preparation and initial fixation:

[0057] The medical staff first fixes the two ends of the adjustable strap 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 patient's limb where hemostasis is required, and adjust the position so that the annular outer elastic pressing pad 27 and the inner elastic pressing pad 28 of the annular connecting plate 24 are roughly aligned above the patient's artery. At this time, attention should be paid to the direction and position of the upper annular frame 2 to ensure that subsequent operations proceed smoothly.

[0059] Fixation of the device on the limb:

[0060] Pick up the adjustable strap 39 and wrap it around the patient's limb. According to the thickness of the patient's limb and the actual situation, adjust the tightness of the strap appropriately so that it can firmly fix the device on the limb. At the same time, ensure the patient's comfort and avoid excessive tightness that causes unnecessary pressure on the limb.

[0061] Initial adjustment of the core pressing mechanism:

[0062] The medical staff gently presses the upper pressing pad 36 provided on the handle 35 of the core pressing mechanism 1, causing it to initially move within the space formed by the upper annular frame 2 and the sliding track 4. At this point, the guide block 13 on the outer wall 9 of the core functional housing 8 slides within the long guide groove 5 on the inner side of the sliding track 4, providing guidance and ensuring smooth and accurate movement of the core functional housing 8. The medical staff also experiences the smoothness of movement and the coordination between the various components.

[0063] During the movement, pay attention to the relative position relationship between the core functional shell 8 as a whole, the annular outer elastic pressing pad 27, 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 their finger on the upper pressing pad 36 above the handle portion 35 of the handle screw 32 and gently presses downward. During this pressing process, the core functional housing 8 gradually moves downward within the space formed by the upper annular frame 2 and the sliding track 4, while the guide block 13 continues to slide within the long guide groove 5, ensuring the stability of the movement direction.

[0066] As the core functional 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 is in uniform contact with the skin to avoid excessive or insufficient local pressure. When observed or with the help of other detection means, such as the numerical changes 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 pressure from the inner elastic pressure pad:

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

[0069] While rotating the handle 35, closely observe the degree of protrusion of the inner elastic pressure pad 28 and the effect of pressure on the artery. Furthermore, since the stud portion 33 of the handle screw 32 penetrates the tension spring 16 and the middle portion of the traction plate 14, and the lower portion of the tension spring 16 abuts the middle portion of the lower wall 17 of the core functional housing 8, and the auxiliary pulling frame 18 is fixed to the upper middle portion of the traction plate 14, the movement of the stud portion 33 will have a certain impact on these components, but will not affect the overall pressing operation. Once you are sure that the inner elastic pressure pad 28 is accurately and effectively pressing the artery of the patient's limb, stop rotating the handle 35.

[0070] Pressure monitoring and adjustment:

[0071] During the hemostasis process, the annular pressure sensor 23 at the lower edge of the upper wall 19 of the core functional housing 8 monitors the pressure at the pressing site 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 to it.

[0072] Medical staff can observe the pressure value displayed on the pressure display 37 at any time and judge whether the current compression pressure is appropriate based on actual needs and the patient's specific situation. If the pressure is too high, it may cause damage to the patient's limbs. In this case, the handle portion 35 of the handle screw 32 can be rotated in the opposite direction to reduce the pressure of the pressing block 34 on the inner elastic pressing pad 28, thereby reducing the compression 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 compression pressure until the pressure value displayed on the pressure display 37 is within the appropriate range, ensuring hemostasis while ensuring the safety and comfort of the patient.

[0073] Device removal after hemostasis:

[0074] Once the hemostasis procedure is complete, the medical professional needs to remove the device from the patient's limb. First, grasp the auxiliary pull frame 18 with one hand and slowly pull it upward. As the auxiliary pull frame 18 moves upward, it drives the traction plate 14 upward. The ends of the side panels 15 on the traction plate 14 are fixedly connected to the lower inner side of the vertical elastic plate 11, causing the vertical elastic plate 11 to deform. Simultaneously, the auxiliary spring 22 is deformed and compressed due to the tension.

[0075] During this process, the limiting teeth 12 on the lower outer portion of the vertical elastic plate 11 gradually disengage from the limiting tooth groove 6 provided in the elongated guide groove 5. After the limiting teeth 12 are completely disengaged from the limiting tooth groove 6, the auxiliary puller 18 is continuously pulled, and the core functional housing 8 can now move relatively freely outward within the space formed by the upper annular frame 2 and the sliding track 4, driving the lower portion of the annular outer elastic pressing pad 27 and the inner elastic pressing pad 28 of the annular connecting plate 24 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] To ensure the hygiene and performance of the device the next time it is used, the device needs to be cleaned after use. Since the outer side of the vertical portion 25 of the annular connecting plate 24 and the inner side of the annular pressure sensor 23 are fixedly connected by a threaded connection, the annular connecting plate 24 can be easily removed from the core functional housing 8.

[0079] The disassembled annular connecting plate body 24 and the annular outer elastic pressing pad 27 and the inner elastic pressing pad 28 and other components are cleaned and disinfected with appropriate detergents and disinfecting tools to remove the remaining blood, stains, bacteria and other contaminants. After cleaning, the components are dried in the air or wiped dry with a clean towel, and then the annular connecting plate body 24 is reinstalled on the core function shell 8 according to the correct installation method to ensure that the components are firmly connected and ready for the next use. At the same time, the other components 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 shell 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 Application: The ingenious design of the upper annular frame 2, sliding track 4, and core functional housing 8 within the core pressing mechanism 1 ensures that the annular outer elastic pressing pad 27 and inner elastic pressing pad 28 are precisely aligned with the patient's arteries. The stable sliding of the guide block 13 within the elongated guide groove 5 not only provides precise guidance for the movement of the core functional housing 8, but also allows the pressing pads to be flexibly adjusted according to actual needs, thereby ensuring precise pressure on the arteries. This significantly improves the success rate and effectiveness of hemostasis and effectively reduces hemostasis failures or delays caused by inaccurate pressure placement.

[0082] The inner elastic pressure pad 28 achieves precise, central compression of the artery through fine adjustment of the handle screw 32. The threaded engagement of the stud portion 33 of the handle screw 32 with the nut 31, along with the precise action of the pressure block 34 on the inner elastic pressure pad 28, allows medical personnel to precisely control the force and depth of compression based on the patient's specific condition, such as vessel thickness and bleeding severity. This prevents damage to surrounding tissues caused by excessive pressure and prevents incomplete hemostasis caused by insufficient pressure.

[0083] Comfort and safety are both important: The adjustable strap 39 is designed with patient comfort and device stability in mind. By securing its ends to the side connecting ears 3 and allowing for flexible adjustment based on the patient's limb's specific position, the device is securely fastened to the limb during use, preventing displacement that could affect hemostasis. It also avoids unnecessary pressure and discomfort on the patient's limb due to overtightening, effectively improving patient comfort and tolerance during hemostasis and helping them better cooperate with treatment.

[0084] The structural design of the annular connecting plate 24, particularly the curved elastic plate 30 and rubber ring 29 on the underside of the transverse portion 26, significantly enhances the patient experience while ensuring effective compression. The curved elastic plate 30 better conforms to the curves of the limb, evenly distributing pressure and reducing localized pressure points. The rubber ring 29 further increases the softness and friction of the contact pad with the skin, preventing it from slipping during use. This improves compression stability and comfort, reducing pain and discomfort during hemostasis.

[0085] Pressure Visualization and Controllability: The electrical connection between the pressure display 37 and the annular pressure sensor 23 provides medical staff with intuitive, real-time pressure data. Throughout the hemostasis process, medical staff can accurately monitor the pressure at the site of application based on the value displayed on the pressure display 37, enabling timely and accurate adjustments to the handle screw 32 for precise control of pressure. This visual pressure monitoring system not only improves operational safety but also makes the hemostasis process more scientific and standardized, significantly reducing the risk of complications caused by improper pressure, such as localized tissue ischemia and congestion.

[0086] Easy Cleaning and Maintenance: The threaded connection between the annular connecting plate 24 and the annular pressure sensor 23 greatly facilitates cleaning and maintenance of the device. After use, medical personnel can easily remove the annular connecting plate 24 and its attached pressure pad for comprehensive and thorough cleaning and disinfection, effectively removing any residual blood, stains, and bacteria, ensuring the device's sanitary condition meets medical standards and reducing the risk of cross-infection. This easily disassembled design also facilitates regular inspection and maintenance of various components, allowing for the timely identification and replacement of potentially worn or damaged parts, extending the device's service life and improving its reliability and cost-effectiveness.
