Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a spiral compression hemostat with a safety lock. Background Art

[0002] In today's society, with the improvement of living conditions and changes in working methods, coronary heart disease has become a major killer of human beings, attracting more and more attention from people. Percutaneous transluminal coronary angioplasty (PTCA) has become one of the main means of treating coronary heart disease. There are two puncture routes: femoral artery and radial artery. Femoral artery puncture has many inconveniences and disadvantages, while radial artery puncture has better effects. Interventional treatment via radial artery is becoming more and more popular. After interventional surgery, the hemostasis technology of radial artery puncture site has developed in recent years.

[0003] At present, the hemostats on the market mainly include balloon compression type, spiral compression type and direct compression type. However, due to the limitation of structural principle, the existing spiral compression type hemostats will block the puncture point after compressing it, and it is not convenient to observe whether the puncture point is bleeding or not. Therefore, even if the puncture point is already in a state of slight bleeding, medical staff cannot make an accurate judgment quickly. Usually, they need to wait until the amount of bleeding reaches a certain level before they can see the bleeding, which reduces the work efficiency of medical staff and the user experience of patients. In addition, the spiral compression type hemostats have the feature of convenient adjustment of the compression force. Although this feature can facilitate medical staff to improve their work efficiency, it also allows patients to easily adjust the compression force, which greatly increases the probability of misoperation, causing great hidden dangers to the patient's life safety, and causing medical staff to need to continuously check whether the compression force of the hemostats on the puncture point is within the appropriate range, which greatly increases the workload of medical staff.

[0004] There is no effective solution to the problem that the spiral compression hemostat in the related art cannot be locked in the working state and is prone to misoperation, resulting in low safety in use.

[0005] Therefore, the inventor, relying on his many years of experience and practice in related industries, proposes a spiral compression hemostat with a safety lock to overcome the defects of the prior art. Summary of the invention

[0058] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0059] like Figures 1 to 15As shown, the present invention provides a spiral compression hemostat with a safety lock, which includes a compression plate 4, a slider 3, a buckle 8, a mounting plate 1 and a fixing belt 5, wherein the compression plate 4 is used to compress the puncture position, the slider 3 is used to adjust the compression force of the compression plate 4 on the puncture position, the buckle 8 is used to lock the slider 3, and the mounting plate 1 and the fixing belt 5 cooperate to fix the slider 3 to the patient's wrist, wherein: an adjusting knob 2 is sleeved on the outer side of the slider 3, and the adjusting knob 2 and the slider 3 are connected by threads; a mounting hole 101 is opened on the mounting plate 1, and the slider 3 can be slidably arranged in the mounting hole 101 up and down, and a limiting ring is arranged on the outer side of the mounting hole 101 above the mounting hole 101 along the circumference of the mounting hole 101. The bottom of the adjusting knob 2 is provided with a first annular limiting boss 204 matching the limiting slot 102 along the circumference of the adjusting knob 2, and the first limiting boss 204 is embedded in the limiting slot 102 so that the adjusting knob 2 can be rotatably connected to the mounting plate 1. A notch connected to the limiting slot 102 is provided at the edge of the mounting plate 1, and the buckle 8 can be detachably arranged at the notch. A plurality of first positioning teeth 803 are provided on the buckle 8. The bottom of the adjusting knob 2 is located below the first limiting boss 204 and is provided with a plurality of second positioning teeth 203. Each second positioning tooth 203 can mesh with the corresponding first positioning teeth 803. 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 belt 5 are respectively connected to the mounting plate 1.

[0060] In the present invention, a mounting hole 101 is provided on the mounting plate 1, and the bottom edge of the adjusting knob 2 can be rotatably fixed on the inner wall of the mounting hole 101. The adjusting knob 2 is sleeved on the outer side of the slider 3, and the adjusting knob 2 and the slider 3 are threadedly connected. A compression plate 4 is provided at the bottom of the slider 3. The slider 3 can be adjusted to move up and down in the mounting hole 101 by rotating the adjusting knob 2, so as to control the compression plate 4 at the bottom of the slider 3 to apply compression force to the perforation position of the patient, thereby ensuring the hemostasis effect. In addition, a limit screw is provided on the edge of the mounting plate 1. The notch connected to the card slot 102 has a buckle 8 detachably provided at the notch. After the compression plate 4 is adjusted to apply appropriate pressure to the patient's puncture position, the position of the compression plate 4 can be positioned by meshing the multiple first positioning teeth 803 on the buckle 8 with the multiple second positioning teeth 203 on the adjusting knob 2, thereby preventing the patient's misoperation from causing excessive pressure on the puncture position. At the same time, it can also avoid the situation where the hemostat loosens and causes the pressure to decrease, thereby ensuring a good hemostatic effect on the puncture position.

[0061] Further, such as Figures 1 to 6As shown, the slider 3 is a cylindrical structure with an opening at the top and a sealing at the bottom arranged in the vertical direction, the adjusting knob 2 is a cylindrical structure with an opening at the top and an opening at the bottom arranged in the vertical direction, an external thread 301 is arranged on the outer wall of the slider 3, an internal thread 201 is arranged on the lower inner wall of the adjusting knob 2, and the adjusting knob 2 and the slider 3 are connected by the internal thread 201 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, and the adjusting knob 2 drives the slider 3 to move up and down in the vertical direction through the threaded connection structure, thereby adjusting the position of the slider 3 in the mounting hole 101, ensuring that the compression plate 4 can apply compression force to the puncture position.

[0062] In an optional embodiment of the present invention, Figure 2 , Figure 4 , Figure 6 As shown, at least one guide boss 302 is provided on the outer wall of the slider 3 to limit the rotation of the slider 3 relative to the mounting plate 1. The guide boss 302 is a strip-shaped structure provided along the length direction of the slider 3. The inner wall of the mounting hole 101 is provided with at least one first guide groove 103 matched with the guide boss 302. The guide boss 302 can be slidably embedded in the first guide groove 103. The guide boss 302 cooperates with the first guide groove 103 to limit the slider 3, ensuring that when the adjusting knob 2 is turned, the slider 3 does not rotate with the adjusting knob 2, but moves up and down in the vertical direction.

[0063] Further, such as Figure 2 , Figure 4 As shown, a section is provided on the outer wall of the slider 3 along the length direction of the slider 3, the distance between the center position of the slider 3 and the section is smaller than the outer diameter of the slider 3, the guide boss 302 is provided on the section, and the radial distance between the axial position of the slider 3 and the outer wall of the guide boss 302 is smaller than the outer diameter of the slider 3, so that a gap is left between the guide boss 302 and the inner wall of the adjusting knob 2, ensuring that the guide boss 302 will not hinder the rotation of the adjusting knob 2 on the slider 3 while limiting the rotation of the slider 3.

[0064] In this embodiment, the number of the guide bosses 302 is two, and the two guide bosses 302 are symmetrically arranged along the radial direction of the slider 3 .

[0065] In an optional embodiment of the present invention, Figure 2 , Figure 4 , Figure 6As shown, the top fixed sleeve of the slider 3 is provided with a retaining ring 7, and the retaining ring 7 is a circular ring structure arranged in the horizontal direction. The middle part of the retaining ring 7 is provided with an observation port 701 connected with the inside of the slider 3, and the inner wall of the adjusting knob 2 is provided with a circular ring-shaped second limiting boss 205 along the circumference of the adjusting knob 2. The moving position of the slider 3 is limited by the retaining ring 7. When the slider 3 moves to the lowest position, the bottom of the retaining ring 7 abuts against the top of the second limiting boss 205, thereby preventing the slider 3 from being separated from the mounting plate 1.

[0066] In an optional embodiment of the present invention, the slider 3 is made of a transparent hard material, and the compression plate 4 is made of a transparent flexible material. The observation port 701 on the retaining ring 7, the interior of the slider 3 and the compression plate 4 form an observation channel for viewing the patient's puncture position. Medical staff can observe the puncture position through the observation port 701 when the compression plate 4 applies pressure to the puncture position, ensuring that the compression plate 4 accurately applies pressure to the puncture position. At the same time, it is convenient to understand in real time whether there is bleeding at the puncture position, which is convenient for the operation of medical staff and greatly improves the work efficiency of medical staff.

[0067] In an optional embodiment of the present invention, Figure 7 , Figure 8 As shown, the buckle 8 includes a buckle body 801 and an elongated clip arm 802 arranged on both sides of the buckle body 801, and first clip holes 105 are respectively opened on the inner walls of the limiting clip slot 102 located on both sides of the notch and close to the notch, and a first clip boss 8021 matching the first clip hole 105 is arranged on the outer wall of each clip arm 802 at a position corresponding to the first clip hole 105, and each clip arm 802 is respectively inserted into the limiting clip slot 102 along the limiting clip slot 102 from both sides of the notch, and the first clip boss 8021 on each clip arm 802 is embedded in the corresponding first clip hole 105, and the buckle 8 is fixed by the first clip boss 8021 on the clip arm 802 matching with the first clip hole 105 on the inner wall of the limiting clip slot 102, which can not only limit the maximum stroke of the buckle 8, but also ensure that the buckle 8 is stably connected to the mounting plate 1.

[0068] In this embodiment, if Figures 7 to 10 As shown, each first positioning tooth 803 is arranged side by side in the horizontal direction on the outer wall of the buckle body 801 close to the notch, and each second positioning tooth 203 is arranged at the bottom of the adjusting knob 2 along the circumference of the adjusting knob 2. The adjusting knob 2 is positioned by the engagement of each first positioning tooth 803 with each second positioning tooth 203, and then the slider 3 is locked to ensure that the position of the slider 3 does not change, thereby improving the safety of the hemostat.

[0069] Further, such as Figure 7 , Figure 8 , Fig.11 As shown, at least one guide rod 804 is provided at the bottom of the buckle body 801 in the horizontal direction, one end of the guide rod 804 is connected to the buckle body 801, and the extension direction of the other end of the guide rod 804 is the same as the extension direction of each clamping arm 802. At least one second guide groove 104 connected to the notch and corresponding to the position of the guide rod 804 is provided on the mounting plate 1, and the guide rod 804 is inserted into the corresponding second guide groove 104. When the buckle 8 is clamped at the notch position, the guide rod 804 plays a guiding role, and the guide rod 804 cooperates with the second guide groove 104 to limit the buckle 8, further improving the stability of the connection between the buckle 8 and the mounting plate 1.

[0070] Further, such as Figure 12 to Figure 14 As shown, a through hole 8011 is provided on the buckle body 801, which passes through the top and bottom surfaces of the buckle body 801. A "U"-shaped spring sheet 805 is horizontally arranged in the through hole 8011. The sealed end of the spring sheet 805 is connected to the inner wall of the through hole 8011 on one side close to each first positioning tooth 803. At least one second clamping boss 8051 is provided at the bottom of the spring sheet 805. At least one second clamping hole 106 is provided on the mounting plate 1, and the second clamping boss 8051 is embedded in the second clamping hole 106. When unlocking the hemostat, the two ends of the spring sheet 805 can be pressed to separate the second snap-fitting boss 8051 on the spring sheet 805 from the second snap-fitting hole 106, and the buckle 8 can be pulled away from the notch to separate the first positioning tooth 803 on the buckle 8 from the second positioning tooth 203 on the adjusting knob 2, and the adjusting knob 2 and the slider 3 can resume a freely rotatable state, so that the position of the compression plate 4 and the compression force applied to the puncture position can be adjusted.

[0071] In an optional embodiment of the present invention, Figure 1 , Figure 2 , Figure 5 As shown, arc-shaped support bosses 6 are respectively provided at the bottom of the mounting plate 1 on two opposite sides of the mounting hole 101. The support bosses 6 abut against the patient's arm, thereby supporting the mounting plate 1, facilitating the matching with the patient's wrist, improving the wearing comfort, and leaving a certain space between the bottom of the mounting plate 1 and the patient's arm, facilitating the adjustment of the position of the slider 3.

[0072] In an optional embodiment of the present invention, Figures 1 to 3 , Figure 5 , Fig. 9As shown, anti-slip patterns 202 are provided on the outer wall of the adjusting knob 2. The anti-slip patterns 202 are multiple convex ribs provided on the outer wall of the adjusting knob 2 along the vertical direction. The convex ribs are evenly arranged on the outer wall of the adjusting knob 2 along the circumference of the upper adjusting knob 2. The anti-slip patterns 202 increase the friction force of the outer wall of the adjusting knob 2, making it convenient for medical staff to screw the adjusting knob 2 and to adjust the position of the slider 3.

[0073] In an optional embodiment of the present invention, Figure 2 As shown, the two ends of the fixing belt 5 are respectively connected to the two opposite edges of the mounting plate 1 , and a Velcro 9 is provided on the fixing belt 5 , so that it can be fixedly worn on the wrists of different patients, and has a wider applicability.

[0074] The working principle of the spiral compression hemostat with a safety lock of the present invention is: the slider 3 is fixed at the patient's puncture position by cooperating with the fixing belt 5 and the mounting plate 1, and the medical staff adjusts the up and down movement position of the slider 3 by turning the adjusting knob 2, so that the compression plate 4 located at the bottom of the slider 3 applies appropriate compression force to the puncture position, thereby achieving a hemostatic effect on the puncture position. When the adjusting knob 2 is screwed, the first positioning teeth 803 on the buckle 8 are separated from the second positioning teeth 203 on the adjusting knob 2, and the buckle 8 will not lock the slider 3 and the adjusting knob 2; after the pressure force of the compression plate 4 on the puncture position is adjusted, the buckle 8 is pressed toward the notch, so that the clamping arm 802 is inserted into the limiting clamping groove 102 along the limiting clamping groove 102, and the first clamping boss 8021 on the clamping arm 802 is embedded in the first clamping hole 105, and the first positioning teeth 803 on the buckle 8 are meshed with the second positioning teeth 203 on the adjusting knob 2, thereby locking the slider 3 and the adjusting knob 2. At this time, the guide rod 804 on the buckle 8 is inserted into the corresponding second guide groove 104 on the mounting plate 1, and the second clamping boss 8051 on the spring sheet 805 is embedded in the second clamping hole 106 on the mounting plate 1, thereby limiting and fixing the buckle 8. When the hemostat needs to be unlocked, the two ends of the spring sheet 805 are pressed to separate the second snap-fitting boss 8051 on the spring sheet 805 from the second snap-fitting hole 106 on the mounting plate 1, and the buckle 8 is pulled away from the notch, and the first positioning tooth 803 on the buckle 8 is separated from the second positioning tooth 203 on the adjusting knob 2, thereby releasing the lock on the adjusting knob 2 and the slider 3, and the adjusting knob 2 and the slider 3 resume a freely rotatable state.

[0075] The characteristics and advantages of the spiral compression hemostat with a safety lock of the present invention are:

[0076] 1. The spiral compression hemostat with a safety lock moves the slider 3 up and down in the mounting hole 101 of the mounting plate 1 by rotating the adjusting knob 2, thereby ensuring that the compression plate 4 can apply compression force to the patient's puncture position, ensuring that the compression force is applied to the puncture position accurately and stably, and ensuring that an effective hemostasis effect is achieved.

[0077] 2. The spiral compression hemostat with a safety lock is provided with a detachable buckle 8 on the mounting plate 1. After the compression plate 4 is adjusted to apply appropriate compression force to the patient's puncture position, the adjustment knob 2 and the slider 3 are locked by the buckle 8, thereby positioning the compression plate 4 to prevent the patient's misoperation from causing excessive compression force on the puncture position. At the same time, it can also prevent the hemostat from loosening and causing a reduction in compression force, thereby ensuring a good hemostatic effect on the puncture position.

[0078] 3. In the spiral compression hemostat with a safety lock, the slider 3 and the compression plate 4 are both made of transparent materials, and an observation port 701 is provided on the retaining ring 7. An observation channel for viewing the patient's puncture position is formed through the observation port 701 of the retaining ring 7, the interior of the slider 3 and the compression plate 4. Medical staff can observe the puncture position through the observation port 701 to ensure that the compression plate 4 accurately applies pressure to the puncture position. At the same time, it is convenient to understand in real time whether there is bleeding at the puncture position, which is convenient for medical staff to operate and greatly improves the work efficiency of medical staff.

[0079] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
