Description

Technical Field

[0001] This invention belongs to the field of hemostatic device technology, specifically relating to a hemostatic auxiliary compression device. Background Technology

[0002] In the cardiology department, medical staff need to perform CAG and PCI surgery through the patient's radial artery. Compared with the femoral artery approach, it has the advantages of convenient hemostasis, patients can get out of bed and move around in the early stage, less damage, faster recovery, and shorter hospital stay. After the coronary angiography is completed, the patient needs to wear a compression hemostat to compress the puncture site and avoid bleeding at the puncture site.

[0003] Conventional hemostatic devices adjust the tightness and pressure by adjusting the height of the bandage and pad. Users can determine the pad's position and thus the tightness and pressure by adjusting the height of the lever. However, the applicant discovered a flaw in the device during use. Because different patients have different arm sizes and radial artery depths, judging the pad's position and pressure solely by adjusting the lever is inaccurate. Medical staff cannot accurately determine the pressure of the pad on the patient's arm, requiring multiple adjustments to achieve the appropriate pressure range for hemostasis, which is quite cumbersome. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a hemostatic auxiliary compression device to solve the problem that medical staff cannot obtain the working pressure of existing hemostatic devices, which leads to the need for medical staff to frequently adjust the adjustment rod of the hemostatic device.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A hemostatic auxiliary compression device, comprising:

[0007] Mounting housing, on which mounting blocks and mounting rods are connected, a strap is connected to the mounting rod and a Velcro strap is connected to the strap, and a first cover plate is connected to the mounting housing;

[0008] A sliding cylinder is slidably connected to the mounting shell, and an annular plate is fixedly connected to the upper end of the sliding cylinder. A threaded cylinder is rotatably connected to the annular plate, and the threaded cylinder is threadedly connected to the first cover plate.

[0009] A pressure feedback assembly is connected to the ring plate, and a force-sensitive resistor sheet that contacts the pressure feedback assembly is connected to the first cover plate. A pressure feedback device that is electrically connected to the force-sensitive resistor sheet is also connected to the first cover plate.

[0010] A rubber sheet is connected to the end of the slide cylinder, and an adjustment component is provided inside the slide cylinder to adjust the height of the protrusion at the end of the rubber sheet.

[0011] Preferably, the pressure feedback assembly includes an outer cylinder fixedly connected to the ring plate, a slide rod slidably connected to the end of the outer cylinder, and a second spring disposed inside the outer cylinder. The end of the slide rod is connected to the force-sensitive resistor sheet, and the second spring is pre-compressed, that is, one end of the second spring abuts against the inner wall of the outer cylinder and the other end abuts against the end of the slide rod.

[0012] Preferably, a first spring is sleeved on the outside of the slide cylinder, with one end of the first spring abutting against the ring plate and the other end abutting against the inner wall of the mounting shell.

[0013] Preferably, the pressure feedback device has a display screen on its surface for displaying the pressure value of the slide.

[0014] Preferably, the adjusting assembly includes a mounting bracket fixedly connected to the inner wall of the slide cylinder, a threaded rod threadedly connected to the mounting bracket, and a second cover plate snapped onto the threaded cylinder. The upper end of the threaded rod extends out of the second cover plate, and a pressure plate is rotatably connected to the end of the threaded rod. The pressure plate is fixedly connected to the rubber sheet.

[0015] Preferably, the inner wall of the slide cylinder is fixedly connected with a plurality of end blocks arranged in a circular array at equal intervals. A first connecting block is hinged to the end block, and a second connecting block is slidably connected to the end of the first connecting block. The end of the second connecting block is hinged to the pressure plate, and both the first connecting block and the second connecting block abut against the rubber sheet.

[0016] Preferably, a stop block is fixedly connected to the end block, and the stop block is attached to the upper side of the first connecting block.

[0017] Preferably, the lower end of the rubber sheet is provided with a protrusion.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention incorporates a pressure feedback component, a force-sensitive resistor, and a pressure feedback device. After the patient wears the mounting shell via straps and Velcro, the rubber sheet is aligned with the area near the puncture site, applying pressure to the skin near the radial artery to limit bleeding. The pressure of the patient's limb on the rubber sheet is transmitted to the pressure feedback component via a sliding cylinder, which then applies pressure to the force-sensitive resistor. The resistance value of the force-sensitive resistor changes according to the applied pressure, thereby altering the current value read by the pressure feedback device. The pressure feedback device converts the current value into a pressure value and displays it. Users can monitor the pressure between the rubber sheet and the patient's skin in real time through the pressure feedback device, allowing medical staff to adjust the hemostatic pressure value to an appropriate range.

[0020] By setting a first spring and a second spring, when the patient's arm muscles or blood vessels swell, the first spring and the second spring can be compressed and shortened, thereby slightly increasing the space for movement of the patient's arm and blood vessels, and avoiding excessive restraint force from the tether on the patient's arm, which could lead to tissue damage.

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-6 As shown, a hemostatic auxiliary compression device includes:

[0031] Mounting housing 1, mounting block 2 and mounting rod 3 are connected to mounting housing 1, strap 4 is connected to mounting rod 3 and Velcro 5 is connected to strap 4, and first cover plate 6 is connected to mounting housing 1.

[0032] The slide cylinder 7 is slidably connected to the mounting shell 1, and the upper end of the slide cylinder 7 is fixedly connected to the ring plate 8. The ring plate 8 is rotatably connected to the threaded cylinder 9, and the threaded cylinder 9 is threadedly connected to the first cover plate 6.

[0033] A pressure feedback component 11 is connected to the ring plate 8, and a force-sensitive resistor 12 that contacts the pressure feedback component 11 is connected to the first cover plate 6. A pressure feedback device 13 that is electrically connected to the force-sensitive resistor 12 is also connected to the first cover plate 6.

[0034] A rubber sheet 17 is attached to the end of the slide cylinder 7.

[0035] As can be seen from the above, by setting up the pressure feedback component 11, the force-sensitive resistor 12, and the pressure feedback device 13, after the patient wears the mounting shell 1 through the strap 4 and Velcro 5, the rubber sheet 17 is aligned with the vicinity of the puncture site, applying pressure to the skin near the radial artery to limit radial artery bleeding. The pressure of the patient's limb on the rubber sheet 17 is transmitted to the pressure feedback component 11 through the slide cylinder 7, and then the pressure feedback component 11 applies pressure to the force-sensitive resistor 12. The resistance value of the force-sensitive resistor 12 changes according to the pressure, which in turn causes the current value read by the pressure feedback device 13 to change. The pressure feedback device 13 converts the current value into a pressure value and displays it. The user can use the pressure feedback device 13 to understand the pressure between the rubber sheet 17 and the patient's skin in real time, which makes it easier for medical staff to adjust the hemostasis pressure value to an appropriate range.

[0036] Please see Figures 4-6 As shown, the pressure feedback assembly 11 includes an outer cylinder 111 fixedly connected to the ring plate 8, a slide rod 112 slidably connected to the end of the outer cylinder 111, and a second spring 113 disposed inside the outer cylinder 111. The end of the slide rod 112 is connected to the force-sensitive resistor 12, and the second spring 113 is pre-compressed, that is, one end of the second spring 113 abuts against the inner wall of the outer cylinder 111, and the other end abuts against the end of the slide rod 112.

[0037] As can be seen from the above, the pressure between the patient's limb and the rubber sheet 17 is transmitted to the ring plate 8 through the slide cylinder 7. After the ring plate 8 is subjected to force, it moves upward to compress the second spring 113. After the second spring 113 is compressed, it feeds back the force to the slide rod 112, causing the pressure value of the slide rod 112 on the force-sensitive resistor 12 to change. This, in turn, causes the resistance value of the force-sensitive resistor 12 to change, resulting in a change in the current value of the internal circuit of the pressure feedback device 13. According to conventional circuit knowledge, the change in resistance value is calculated from the current value, and then the change in resistance value is calculated. Thus, the pressure value between the rubber sheet 17 and the patient's limb can be obtained. The pressure feedback device 13 is provided with a display screen on its surface for displaying the pressure value of the slide cylinder 7. The pressure value can be displayed on the display screen in real time.

[0038] Please see Figures 5-6 As shown, a first spring 10 is sleeved on the outside of the slide cylinder 7. One end of the first spring 10 abuts against the ring plate 8 and the other end abuts against the inner wall of the mounting shell 1. The first spring 10 can provide pressure to the ring plate 8, so that the second spring 113 is in a pre-compressed state, which facilitates the timely feedback of the deformation of the second spring 113 to the slide rod 112, making the pressure signal received by the force-sensitive resistor 12 more accurate.

[0039] To increase the accuracy and force of the rubber sheet 17 in applying pressure to the patient's puncture site, the lower end of the rubber sheet 17 is protruding. The rubber sheet 17 can be adhered to the end of the slide cylinder 7, making it convenient for users to replace the used rubber sheet 17.

[0040] Example 2:

[0041] Please see Figures 1-6 As shown, a hemostatic auxiliary compression device includes:

[0042] Mounting housing 1, mounting block 2 and mounting rod 3 are connected to mounting housing 1, strap 4 is connected to mounting rod 3 and Velcro 5 is connected to strap 4, and first cover plate 6 is connected to mounting housing 1.

[0043] The slide cylinder 7 is slidably connected to the mounting shell 1, and the upper end of the slide cylinder 7 is fixedly connected to the ring plate 8. The ring plate 8 is rotatably connected to the threaded cylinder 9, and the threaded cylinder 9 is threadedly connected to the first cover plate 6.

[0044] A pressure feedback component 11 is connected to the ring plate 8, and a force-sensitive resistor 12 that contacts the pressure feedback component 11 is connected to the first cover plate 6. A pressure feedback device 13 that is electrically connected to the force-sensitive resistor 12 is also connected to the first cover plate 6.

[0045] A rubber sheet 17 is connected to the end of the slide cylinder 7, and an adjustment component is provided inside the slide cylinder 7 to adjust the height of the protrusion at the end of the rubber sheet 17.

[0046] As can be seen from the above, by setting up the pressure feedback component 11, the force-sensitive resistor 12, and the pressure feedback device 13, after the patient wears the mounting shell 1 through the strap 4 and Velcro 5, the rubber sheet 17 is aligned with the vicinity of the puncture site, applying pressure to the skin near the radial artery to limit radial artery bleeding. The pressure of the patient's limb on the rubber sheet 17 is transmitted to the pressure feedback component 11 through the slide cylinder 7, and then the pressure feedback component 11 applies pressure to the force-sensitive resistor 12. The resistance value of the force-sensitive resistor 12 changes according to the pressure, which in turn causes the current value read by the pressure feedback device 13 to change. The pressure feedback device 13 converts the current value into a pressure value and displays it. The user can use the pressure feedback device 13 to understand the pressure between the rubber sheet 17 and the patient's skin in real time, which makes it easier for medical staff to adjust the hemostasis pressure value to an appropriate range.

[0047] Please see Figures 4-6 As shown, the pressure feedback assembly 11 includes an outer cylinder 111 fixedly connected to the ring plate 8, a slide rod 112 slidably connected to the end of the outer cylinder 111, and a second spring 113 disposed inside the outer cylinder 111. The end of the slide rod 112 is connected to the force-sensitive resistor 12, and the second spring 113 is pre-compressed, that is, one end of the second spring 113 abuts against the inner wall of the outer cylinder 111, and the other end abuts against the end of the slide rod 112.

[0048] As can be seen from the above, the pressure between the patient's limb and the rubber sheet 17 is transmitted to the ring plate 8 through the slide cylinder 7. After the ring plate 8 is subjected to force, it moves upward to compress the second spring 113. After the second spring 113 is compressed, it feeds back the force to the slide rod 112, causing the pressure value of the slide rod 112 on the force-sensitive resistor 12 to change. This, in turn, causes the resistance value of the force-sensitive resistor 12 to change, resulting in a change in the current value of the internal circuit of the pressure feedback device 13. According to conventional circuit knowledge, the change in resistance value is calculated from the current value, and then the change in resistance value is calculated. Thus, the pressure value between the rubber sheet 17 and the patient's limb can be obtained. The pressure feedback device 13 is provided with a display screen on its surface for displaying the pressure value of the slide cylinder 7. The pressure value can be displayed on the display screen in real time.

[0049] Please see Figures 5-6 As shown, a first spring 10 is sleeved on the outside of the slide cylinder 7. One end of the first spring 10 abuts against the ring plate 8 and the other end abuts against the inner wall of the mounting shell 1. The first spring 10 can provide pressure to the ring plate 8, so that the second spring 113 is in a pre-compressed state, which facilitates the timely feedback of the deformation of the second spring 113 to the slide rod 112, making the pressure signal received by the force-sensitive resistor 12 more accurate.

[0050] The adjustment assembly includes a mounting bracket 14 fixedly connected to the inner wall of the slide cylinder 7, a threaded rod 15 threadedly connected to the mounting bracket 14, and a second cover plate 16 snapped onto the threaded cylinder 9. The upper end of the threaded rod 15 extends out of the second cover plate 16, and a pressure plate 22 is rotatably connected to the end of the threaded rod 15. The pressure plate 22 is fixedly connected to the rubber sheet 17.

[0051] The inner wall of the slide cylinder 7 is fixedly connected to a plurality of end blocks 18 arranged in a circular array at equal intervals. A first connecting block 20 is hinged to the end block 18. A second connecting block 21 is slidably connected to the end of the first connecting block 20. The end of the second connecting block 21 is hinged to the pressure plate 22. Both the first connecting block 20 and the second connecting block 21 abut against the rubber sheet 17.

[0052] As can be seen from the above, when medical staff need to perform hemostasis on patients with relatively slender limbs, in order not to affect the flow of other blood vessels inside the patient's limb, it is necessary to reduce the pressure area of ​​the rubber sheet 17 on the patient's limb. At this time, the threaded rod 15 can be rotated to move it downward. The downward movement of the threaded rod 15 drives the pressure plate 22 to move downward. The pressure plate 22 pushes the rubber sheet 17 downward, making the lower end of the rubber sheet 17 more prominent, and at the same time reducing the area of ​​the lower end of the rubber sheet 17, so that the pressure area of ​​the rubber sheet 17 on the patient's limb is smaller. At the same time, the downward movement of the pressure plate 22 will drive the end of the first connecting block 20 to move downward. The first connecting block 20 then drives the end of the second connecting block 21 to move downward, so that both the first connecting block 20 and the second connecting block 21 are tilted and extended. The first connecting block 20 and the second connecting block 21 abut against the inside of the rubber sheet 17, avoiding the appearance of depression on the outside of the rubber sheet 17, which would reduce the pressure on the patient's skin.

[0053] A stop block 19 is fixedly connected to the end block 18. The stop block 19 is attached to the upper side of the first connecting block 20. The stop block 19 can prevent the first connecting block 20 from rotating upward, so that the first connecting block 20 and the second connecting block 21 can only rotate upward to a horizontal position at most. This ensures that the first connecting block 20 and the second connecting block 21 can limit the upward deformation of the rubber sheet 17 and prevent the rubber sheet 17 from being recessed into the slide cylinder 7.

[0054] To increase the accuracy and pressure of the rubber sheet 17 on the patient's puncture site, the lower end of the rubber sheet 17 is provided with a protrusion.

[0055] In actual use, although the hemostatic pressure of the radial artery varies with gender, age, and other factors, it generally falls within a range of 1 to 5. When using the device, medical personnel can first adjust the pressure to 3 and observe if bleeding stops. If bleeding does not stop, adjust the pressure to 4 and observe again if bleeding stops at the puncture site. Each adjustment increases the pressure by half until bleeding stops at the puncture site. If bleeding stops at the puncture site when the pressure is adjusted to 3, and the patient experiences pain, the pressure can be adjusted to 2. Observe if bleeding stops. If bleeding occurs at the puncture site, increase the pressure to 2.5. If there is no bleeding, adjust to 1.5, and so on. This approach ensures no bleeding at the puncture site while also considering the patient's comfort.
