Description
Technical Field
[0001] The present invention relates to the field of medical devices, and particularly to a spiral compression hemostat capable of indicating the compression force. Background Art
[0002] In today's society, with the improvement of living conditions and the change of working methods, coronary heart disease has become a major killer of humans, attracting more and more attention. Percutaneous transluminal coronary angioplasty (PTCA) has become one of the main means for the treatment of coronary heart disease. There are two puncture approaches: the femoral artery and the radial artery. Femoral artery puncture has many inconveniences and drawbacks, while the effect of radial artery puncture is better. Interventional treatment via the radial artery is becoming more and more popular. In recent years, the hemostasis technology for the radial artery puncture site has developed.
[0003] At present, the hemostats on the market mainly include balloon compression type, spiral compression type, and direct compression type. The existing spiral compression hemostat adjusts the magnitude of the compression force by rotating the position of the threaded mechanism. However, in the actual use process, since most of the knobs for adjusting the compression force in the spiral compression hemostat are designed as symmetric structures, it is difficult for medical staff to identify the number of rotation turns during the process of rotating the adjustment knob, resulting in the inability to accurately adjust the magnitude of the compression force. Medical staff can only rely on the feel of rotating the knob to sense the magnitude of the compression force, and cannot clearly display the compression force, which increases the difficulty of adjustment and requires higher skills and experience in using instruments for medical staff. Once the compression force is too large, it will lead to a decrease in the comfort of the patient, and even cause harm to the patient's body.
[0004] Aiming at the problems of large adjustment difficulty, inability to clearly indicate the magnitude of the compression force, and poor patient experience in the related art of spiral compression hemostats, there is currently no effective solution.
[0005] Therefore, based on the experience and practice of being engaged in the relevant industry for many years, the inventor of the present invention proposes a spiral compression hemostat capable of indicating the compression force to overcome the defects of the prior art. Summary of the Invention

[0047] For a clearer understanding of the technical features, objectives and effects of the present invention, the detailed implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0048] As Figures 1 to 8 shown, the present invention provides a spiral compression hemostat capable of indicating the compression force. The spiral compression hemostat capable of indicating the compression force includes a compression plate 4, a slider 3, a mounting plate 1 and a fixing band 5. The compression plate 4 is used to compress the puncture position. The slider 3 is used to adjust the magnitude of the compression force of the compression plate 4 on the puncture position. The mounting plate 1 and the fixing band 5 cooperate to fix the slider 3 at the wrist of the patient. Among them: An adjustment knob 2 is sleeved on the outer side of the slider 3, and the adjustment knob 2 is threadedly connected to the slider 3. An indicating boss 201 for indicating the rotation angle of the adjustment knob 2 is provided on the outer wall of the adjustment knob 2; A mounting hole 102 is provided on the mounting plate 1. The slider 3 is slidably arranged in the mounting hole 102. Above the mounting hole 102, a limiting groove 103 is circumferentially arranged along the circumference of the mounting hole 102 on the outer side of the mounting hole 102. A circumferential first limiting boss 203 cooperating with the limiting groove 103 is arranged on the bottom of the adjustment knob 2 along the circumference of the adjustment knob 2. The first limiting boss 203 is embedded in the limiting groove 103 so that the adjustment knob 2 and the mounting plate 1 are rotatably connected. A marking portion for indicating the change of the compression force is provided on the mounting plate 1. The compression plate 4 is located below the mounting plate 1 and is connected to the bottom of the slider 3. Both ends of the fixing band 5 are respectively connected to the mounting plate 1.
[0049] The present invention has mounting holes 102 formed in the mounting plate 1. The bottom edge of the adjusting knob 2 is rotatably fixed to the inner wall of the mounting hole 102. The adjusting knob 2 is sleeved outside the slider 3, and the adjusting knob 2 is threadedly connected to the slider 3. A pressing plate 4 is provided at the bottom of the slider 3. By rotating the adjusting knob 2, the slider 3 moves up and down in the mounting hole 102, so as to ensure that the pressing plate 4 can apply a pressing force to the puncture position of the patient, ensuring the hemostatic effect. Moreover, an indicating boss 201 for indicating the rotation angle of the adjusting knob 2 is provided on the outer wall of the adjusting knob 2, and a marking portion for indicating the tightening direction is provided on the mounting plate 1. During the process of rotating and adjusting the adjusting knob 2, the rotation angle and direction can be clearly indicated, enabling a more accurate pressing force to be applied to the puncture position, greatly facilitating the observation and operation of medical staff, and improving the operation accuracy and the comfort of the patient.
[0050] Further, as Figure 5 、 Figure 6 shown, the marking portion includes a first marking portion 106 for indicating an increase in the pressing force and a second marking portion 107 for indicating a decrease in the pressing force. The first marking portion 106 and the second marking portion 107 are respectively provided at the top of the mounting plate 1 and are respectively located on both sides of the mounting hole 102. The rotation direction of the adjusting knob 2 can be clearly shown through the first marking portion 106 and the second marking portion 107. Medical staff can directly know whether to increase or decrease the pressing force during the operation, making the adjustment of the pressing force more accurate.
[0051] Further, as Figure 5 、 Figure 6 shown, the first marking portion 106 can be, but is not limited to, an arrow pointing in the clockwise direction and a "+" sign; the second marking portion 107 can be, but is not limited to, an arrow pointing in the counterclockwise direction and a "-" sign.
[0052] Further, as Figures 1 to 4 shown, the slider 3 is a cylindrical structure with an open top and a closed bottom arranged in the vertical direction. The adjusting knob 2 is a cylindrical structure with an open top and an open bottom arranged in the vertical direction. An external thread 301 is provided on the outer wall of the slider 3, and an internal thread 204 is provided on the lower inner wall of the adjusting knob 2. The adjusting knob 2 and the slider 3 are connected by the cooperation of the internal thread 204 and the external thread 301. Since the adjusting knob 2 is rotatably connected to the mounting plate 1, when the adjusting knob 2 is rotated, the adjusting knob 2 cannot move in the vertical direction. The adjusting knob 2 drives the slider 3 to move up and down in the vertical direction through the threaded connection structure, so as to adjust the position of the slider 3 in the mounting hole 102 and ensure that the pressing plate 4 can apply a pressing force to the puncture position.
[0053] In an alternative embodiment of the present invention, as Figure 2 、 Figure 4 、Figure 6 As shown, at least one guiding boss 302 for restricting the rotation of the sliding block 3 relative to the mounting plate 1 is provided on the outer wall of the sliding block 3. The guiding boss 302 is a strip-shaped structure arranged along the length direction of the sliding block 3. At least one guiding groove 108 matching with the guiding boss 302 is provided on the inner wall of the mounting hole 102. The guiding boss 302 can be slidably inserted into the guiding groove 108. By the cooperation of the guiding boss 302 and the guiding groove 108, a limiting effect is exerted on the sliding block 3, ensuring that when the adjusting knob 2 is rotated, the sliding block 3 does not rotate with the adjusting knob 2 but moves up and down in the vertical direction.
[0054] Further, as Figure 2 shown, a cut surface is arranged on the outer wall of the sliding block 3 along the length direction of the sliding block 3. The distance from the central position of the sliding block 3 to the cut surface is less than the outer diameter of the sliding block 3. The guiding boss 302 is arranged on the cut surface, and the radial distance between the axis position of the sliding block 3 and the outer wall of the guiding boss 302 is less than the outer diameter of the sliding block 3, so as to leave a gap between the guiding boss 302 and the inner wall of the adjusting knob 2, ensuring that while the guiding boss 302 limits the rotation of the sliding block 3, it does not hinder the rotation of the adjusting knob 2 on the sliding block 3.
[0055] In this embodiment, the number of the guiding bosses 302 is two, and the two guiding bosses 302 are symmetrically arranged along the radial direction of the sliding block 3.
[0056] In an alternative embodiment of the present invention, as Figure 2 、 Figure 4 、 Figure 5 shown, a retaining ring 7 is fixedly sleeved on the top of the sliding block 3. The retaining ring 7 is a circular ring-shaped structure arranged along the horizontal direction. A circular ring-shaped second limiting boss 205 is arranged on the inner wall of the adjusting knob 2 along the circumferential direction of the adjusting knob 2. The moving position of the sliding block 3 is limited by the retaining ring 7. When the sliding block 3 moves to the lowest position, the bottom of the retaining ring 7 abuts against the top of the second limiting boss 205, thus avoiding the situation that the sliding block 3 is separated from the mounting plate 1.
[0057] In an alternative embodiment of the present invention, as Figures 1 to 3 shown, a first connecting ring 101 is arranged at one end of the mounting plate 1, and a second connecting ring 105 is arranged at the other end of the mounting plate 1 opposite to the first connecting ring 101. Two ends of the fixing belt 5 are respectively connected with the first connecting ring 101 and the second connecting ring 105.
[0058] Further, the mounting plate 1 and the first connecting ring 101 can be, but are not limited to, integrally formed, and the mounting plate 1 and the second connecting ring 105 can be, but are not limited to, integrally formed.
[0059] In an alternative embodiment of the present invention, as Figures 1 to 8As shown in the figure, the fixing band 5 includes a first wristband 501, a second wristband 502, and an elastic band 503. Both the first wristband 501 and the second wristband 502 are made of flexible and non-stretchable materials, and the elastic band 503 is made of flexible and stretchable materials. One end of the first wristband 501 is connected to one end of the second wristband 502 through the elastic band 503. The other end of the second wristband 502 forms a ring structure and is sleeved on the first connecting ring 101. A hook-and-loop fastener rough surface 504 and a hook-and-loop fastener hook surface 505 are provided on the first wristband 501. The other end of the first wristband 501 is inserted into the second connecting ring 105 and folded to the position where the hook-and-loop fastener rough surface 504 is bonded to the hook-and-loop fastener hook surface 505, so that the fixing band 5 forms a ring structure. During use, as the rotation adjustment knob 2 is rotated, the pressing plate 4 increases the pressing force on the puncture position. Under the action of the pressure, the elastic band 503 gradually elongates, and the distance between the connection positions of the first wristband 501 and the second wristband 502 gradually increases. With different pressing forces, the length of the elastic band 503 is different, and the distance between the connection positions of the first wristband 501 and the second wristband 502 is also different. The magnitude of the pressing force has a linear relationship with the distance between the connection positions of the first wristband 501 and the second wristband 502 (that is, the distance between the connection positions of the first wristband 501 and the second wristband 502 increases with the increase of the pressing force and decreases with the decrease of the pressing force). Therefore, when adjusting the pressing force on the puncture position, the length of the elastic band 503 or the distance between the connection positions of the first wristband 501 and the second wristband 502 can be observed in real time, so as to indicate the magnitude of the pressing force, which can assist medical staff in judging the magnitude of the pressing force, reduce the operation difficulty of the hemostat, improve the comfort of the patient, and ensure the safe and normal use of the hemostat by the patient.
[0060] In an alternative embodiment of the present invention, as Figures 1 to 3 , Figure 5 shown, anti-slip patterns 202 are provided on the outer wall of the adjustment knob 2. The anti-slip patterns 202 are a plurality of ribs arranged vertically on the outer wall of the adjustment knob 2, and the ribs are evenly arranged on the outer wall of the adjustment knob 2 along the circumferential direction of the adjustment knob 2. The friction force of the outer wall of the adjustment knob 2 is increased through the anti-slip patterns 202, which is convenient for medical staff to screw the adjustment knob 2 and facilitates the adjustment of the position of the slider 3.
[0061] The working principle of the spiral compression hemostat capable of indicating the compression force of the present invention is as follows: The slider 3 is fixed at the puncture position of the patient through the cooperation of the fixing band 5 and the mounting plate 1. The medical staff adjusts the vertical movement position of the slider 3 by screwing the adjustment knob 2, so that the compression plate 4 located at the bottom of the slider 3 applies an appropriate compression force to the puncture position, achieving the effect of hemostasis on the puncture position. During the screwing process by the medical staff, the first marking portion 106 and the second marking portion 107 can be used to determine the rotation direction of the adjustment knob 2, thereby determining whether to increase or decrease the compression force on the puncture position, and the position of the indicating boss 201 on the adjustment knob 2 is used to determine the rotation angle of the adjustment knob 2, so that the compression force applied to the puncture position can be more accurate. It can not only meet the requirements for hemostasis of the puncture position, but also facilitate the observation and operation of the medical staff, improve the comfort of the patient, and is suitable for hemostasis of the radial artery puncture site.
[0062] The characteristics and advantages of the spiral compression hemostat capable of indicating the compression force of the present invention are as follows:
[0063] 1. The spiral compression hemostat capable of indicating the compression force moves the slider 3 up and down in the mounting hole 102 of the mounting plate 1 by rotating the adjustment knob 2, so as to ensure that the compression plate 4 can apply a compression force to the puncture position of the patient, ensuring accurate and stable application of the compression force to the puncture position and achieving the effect of effective hemostasis.
[0064] 2. The spiral compression hemostat capable of indicating the compression force is provided with an indicating boss 201 on the outer wall of the adjustment knob 2 to indicate the rotation angle of the adjustment knob 2, and a marking portion for indicating the tightening direction is provided on the mounting plate 1. During the rotation adjustment process of the adjustment knob 2, the rotation angle and direction can be clearly indicated, enabling more accurate application of the compression force to the puncture position, greatly facilitating the observation and operation of the medical staff, and improving the accuracy of the operation and the comfort of the patient.
[0065] 3. In the spiral compression hemostat capable of indicating the compression force, the distance between the connection positions of the first wristband 501 and the second wristband 502 on the fixing band 5 can be used to indicate the magnitude of the compression force, thereby assisting the medical staff in judging the magnitude of the compression force. The medical staff no longer needs to judge by the feel of screwing the adjustment knob 2, reducing the control difficulty of the hemostat, improving the comfort of the patient, ensuring the safe and normal use of the hemostat by the patient, and greatly reducing the probability of the patient's comfort decline or even physical injury caused by excessive compression force.
[0066] The above are only illustrative specific embodiments of the present invention and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention.
