Description

Technical Field

[0001] This invention relates to the field of surgical instruments for femoral artery puncture, specifically to an intelligent sensor-based automatic protector for the femoral artery puncture site. Background Technology

[0002] Extensive searching revealed a Chinese invention patent with publication number CN114699133A, which discloses a multi-angle femoral artery puncture site compression device. This device includes a U-shaped frame composed of a crossbar and a support rod, and a base rotatably connected to the U-shaped frame. The compression device also includes a compression assembly sleeved on the crossbar. This compression assembly includes a connector for sleeved on the crossbar, a connecting rod, a compression rod located at the lower end of the connecting rod, and a negative pressure suction disc. The lower end of the negative pressure suction disc has a hollow interlayer, which is externally connected to a negative pressure pump via a pipe. The device is simple to operate, has high compression accuracy and speed, and effectively avoids the problem of blood splattering due to insufficient compression after the puncture tube is removed.

[0003] Therefore, based on the above search and combined with existing data, in actual use, most patients are in a supine position, which stabilizes blood pressure. However, sitting or standing can cause leg stretching and lower limb congestion, which is not conducive to wound hemostasis. Furthermore, the femoral artery is mostly located on the inner thigh. If the direction of pressure is tilted towards the leg, it can push the skin open, causing tearing of the femoral artery puncture site. In severe cases, it can lead to deterioration of the femoral artery puncture site. At the same time, the wound healing time is longer due to the pressure method. Therefore, we propose a multi-angle femoral artery puncture site compression device. Summary of the Invention

This protector adjusts according to the thickness of the leg and the location of the femoral artery, while accelerating the healing of the femoral artery puncture site.

[0031] 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.

[0032] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an intelligent sensing automatic protector for the femoral artery puncture site.

[0033] Example 1, such as Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, a smart sensor-based automatic protector for femoral artery puncture sites includes...

[0034] The limiting mechanism 1 is used to fix the area around the wound to prevent the wound from tearing due to leg movement and rubbing when applying pressure to stop bleeding, thus slowing down the wound healing speed.

[0035] The protector housing 2 includes a lower housing 3, and an upper housing 4 is hinged to one side of the lower housing 3 for fixing the limiting mechanism 1. Specifically, both the lower housing 3 and the upper housing 4 are arranged at an angle. Since the femoral artery is located on the inner thigh, the upper housing 4 can cover a large area of ​​the inner thigh to facilitate subsequent hemostasis and pressure.

[0036] An angle adjustment mechanism 5 is located inside the upper housing 4. The angle adjustment mechanism 5 includes a movable block 7 that can slide inside the upper housing 4. Specifically, sliding frames 6 are fixedly connected to both sides of the inner wall of the upper housing 4, and the movable block 7 can slide inside the sliding frames 6. An angle fixing mechanism 12 that can fix the movable block 7 is installed on the outside of the movable block 7. A pressing mechanism 8 for pressing the wound to stop bleeding and promote healing is fixedly connected to the bottom of the movable block 7. The pressing mechanism 8 includes a pneumatic telescopic rod 9 that communicates with the outside of the movable block 7. A mounting plate 10 is fixedly connected to the output end of the pneumatic telescopic rod 9. A pressing auxiliary mechanism 11 that can accelerate wound healing and control the pressing pressure according to whether there is bleeding is fixedly connected to the bottom of the mounting plate 10. Specifically, when it is necessary to press the femoral artery puncture site to stop bleeding, the protector housing 2 is moved to the outside of the leg where the femoral artery puncture was performed, and the hinge end of the lower housing 3 and the upper housing 4 is brought close to the other leg, so that the upper housing 4 can cover the inner side of the thigh. Move the protective housing 2 and the upper housing 4 to the top of the femoral artery puncture site. At this time, the angle adjustment mechanism 5 can be adjusted to align the pressing auxiliary mechanism 11 with the position of the femoral artery puncture site. At this time, the angle fixing mechanism 12 and the pneumatic telescopic rod 9 are activated simultaneously. When the pressing mechanism 8 is about to press the femoral artery puncture site to stop bleeding, the angle fixing mechanism 12 fixes the angle adjustment mechanism 5. It can adjust the angle and position of the pressing auxiliary mechanism 11 as it gradually approaches the femoral artery puncture site, so that the pressing position is more accurate. During the pressing of the pressing auxiliary mechanism 11 on the femoral artery puncture site, the middle part of the pressing auxiliary mechanism 11 heats the femoral artery puncture site to accelerate the wound healing speed. The outer periphery of the pressing auxiliary mechanism 11 cools the area around the femoral artery puncture site, so that the blood vessels constrict and the amount of bleeding is reduced. When bleeding is detected, the pressing mechanism 8 is pressurized to increase the pressing force and prevent rebleeding.

[0037] Ventilation mechanism 13 is used to dissipate heat inside the protector housing 2, preventing the body from sweating and growing bacteria due to overheating inside the protector housing 2. Limiting mechanism 1, angle adjustment mechanism 5, angle fixing mechanism 12, pressing mechanism 8, and pressing auxiliary mechanism 11 are linked with ventilation mechanism 13 to achieve pressing on the femoral artery puncture site and assist in the rapid healing of the femoral artery puncture site.

[0038] like Figure 7 and Figure 8 The pressing auxiliary mechanism 11 shown includes a first pressing housing 17 fixedly connected to the bottom of the mounting plate 10. The interior of the first pressing housing 17 is filled with liquid, which is water. An isolation sleeve 18 is fixedly sleeved on the outside of the first pressing housing 17. A semiconductor cooling chip 19 is fixedly installed on the outside of the isolation sleeve 18. The heating surface of the semiconductor cooling chip 19 is in contact with one side of the first pressing housing 17. A second pressing housing 20 is fixedly sleeved on the outside of the isolation sleeve 18. The interior of the second pressing housing 20 is filled with liquid, which is water. The top of the second pressing housing 20 is in contact with the cooling surface of the first pressing housing 17. The bottom of the first pressing housing 17 is flush with the bottom of the second pressing housing 20. A mounting groove 49 is formed on the bottom of the semiconductor cooling chip 19. A patch-type temperature sensor 21 is fixedly installed inside the mounting groove 49. A sealing groove 22 is formed on the bottom of the semiconductor cooling chip 19.

[0039] like Figure 7 As shown, the angle adjustment mechanism 5 also includes sliding rods 15 connected to both ends of the moving block 7. Sliding grooves 16 are provided on both sides of the inner wall of the sliding frame 6. The two sliding rods 15 are slidably connected to the inside of the corresponding sliding grooves 16. An arc-shaped sliding groove 14 is provided on the top of the sliding frame 6. The moving block 7 is arranged in an elliptical shape. The moving block 7 is slidably connected to the bottom of the arc-shaped sliding groove 14, so that the pressing mechanism 8 can be moved along the trajectory of the arc-shaped sliding groove 14 according to the position of the femoral artery puncture site, and moved to the required pressing position. At the same time, rotating the moving block 7 can adjust the pressing angle of the pressing auxiliary mechanism 11 according to the angle of the femoral artery puncture site and the thickness of the leg, so that the pressing position is more secure and avoids the pressing mechanism 8 from pushing the skin open when pressing due to deviation of the pressing angle, which would cause tearing of the femoral artery puncture site and serious deterioration of the femoral artery puncture site.

[0040] like Figure 4 , Figure 7 and Figure 8As shown, the angle fixing mechanism 12 includes a pressing air pump 23 fixedly installed on the top of the inner wall of the upper housing 4. The output end of the pressing air pump 23 is connected to a first telescopic air pipe 50. One end of the first telescopic air pipe 50 is connected to the outside of the moving block 7. The outside of the moving block 7 is connected to two angle fixing airbags 24. The interior of each of the two sliding rods 15 is slidably connected to a limit rod 25. The interior of each of the two sliding rods 15 is airtightly connected to the corresponding limit rod 25. One end of each of the two limit rods 25 is adapted to one side of the corresponding sliding groove 16. Specifically, when the pressing position and angle of the pressing mechanism 8 are adjusted, the pressing air pump 23 is started, and the pressing air pump 23 pressurizes the pressure. The pressure inside the moving block 7 is increased through the first telescopic air tube 50. The limiting rods 25 inside the two sliding rods 15 extend outward and abut against one side of the corresponding sliding groove 16. At the same time, the two angle-fixing airbags 24 outside the moving block 7 gradually expand and abut against the bottom of the arc-shaped sliding groove 14, thus initially fixing the pneumatic telescopic rod 9. During the gradual fitting process, due to the insufficient pressure inside the two angle-fixing airbags 24 and the insufficient thrust of the two limiting rods 25, the position of the compression assist mechanism 11 can be adjusted as the bottom of the compression assist mechanism 11 gradually fits against the femoral artery puncture site, making the compression position more accurate.

[0041] like Figure 4-6As shown, the limiting mechanism 1 includes a limiting air pump 26 fixedly installed on the top of the inner wall of the lower housing 3. Two first fixing airbags 29 are fixedly connected to the outer wall of the lower housing 3, and two second fixing airbags 30 are fixedly connected to the outer wall of the upper housing 4. The limiting air pump 26 can inflate the first fixing airbags 29 and the second fixing airbags 30. The output end of the limiting air pump 26 is connected to a first air pipe 27, and the outside of the first air pipe 27 is connected to a second air pipe 28. The two first fixing airbags 29 are respectively connected to both ends of the second air pipe 28. The two second fixing airbags 30 are connected to the same third air pipe 31 on opposite sides. The bottom of the third air pipe 31 is connected to a fourth air pipe 32. One end of the fourth air pipe 32 is connected to a second telescopic air pipe 33, and one end of the second telescopic air pipe 33 is connected to one end of the first air pipe 27. Specifically, through... The second telescopic air tube 33 is designed so that when the hinged upper housing 4 is opened, the second telescopic air tube 33 extends without causing tensile damage to the first air tube 27 and the fourth air tube 32, thus improving the service life of the limiting mechanism 1. More specifically, when pressure is applied to the femoral artery puncture site, the limiting air pump 26 is activated. The output end of the limiting air pump 26 applies pressure to the inside of the first air tube 27, causing gas to enter the inside of the two first fixing air bags 29 through the second air tube 28. At the same time, gas enters the inside of the fourth air tube 32 through the second telescopic air tube 33, and enters the inside of the two second fixing air bags 30 through the pressing air pump 23 and the third air tube 31. This causes the two first fixing air bags 29 and the two second fixing air bags 30 to expand and limit and fix the protector housing 2 to the leg, preventing the leg from moving during the hemostasis process and causing a change in the pressing position.

[0042] A first limiting frame 34 is fixedly sleeved on the outside of the first air tube 27. The bottom of the first limiting frame 34 is fixedly connected to the bottom of the inner wall of the lower housing 3. A second limiting frame 35 is fixedly connected to the outside of the fourth air tube 32. A limiting groove 36 is formed at the bottom of the inner wall of the lower housing 3. The second limiting frame 35 is slidably connected inside the limiting groove 36. A driven rod 37 is fixedly connected to both sides of the inner wall of the upper housing 4 near the side that is hinged to the lower housing 3. A driven block 38 is rotatably connected to the outside of the driven rod 37. One end of the driven block 38 is fixedly connected to one side of the second limiting frame 35. Specifically, when the limiting air pump 26 is started to pressurize the inside of the second telescopic air tube 33, the second telescopic air tube 33 will be affected by the pressure. Excessive extension reduces the fixation speed of the legs. The aforementioned components ensure that when the hinged upper housing 4 is opened, the driven rod 37 moves, which in turn moves the driven block 38. The driven block 38 then moves the second limiting frame 35 within the limiting groove 36. The movement of the second limiting frame 35 extends the second telescopic air tube 33, thus not affecting the hinge opening between the lower housing 3 and the upper housing 4. Simultaneously, when the limiting air pump 26 is activated to apply pressure to the inside of the second telescopic air tube 33, the first limiting frame 34, the second limiting frame 35, the driven rod 37, and the driven block 38 prevent the second telescopic air tube 33 from extending, thereby increasing the fixation speed of the legs by the limiting mechanism 1.

[0043] Example 2, as Figure 2-4 As shown, a smart sensor-operated automatic protector for femoral artery puncture site, based on Embodiment 1, includes a ventilation mechanism 13 comprising an avoidance groove 39 on one side of the lower housing 3, a clamping plate 40 hinged to one side of the avoidance groove 39, and ventilation grooves 41 on one side of both the avoidance groove 39 and the clamping plate 40. The ventilation grooves 41 allow ventilation of the interior of the protector housing 2. A placement groove 42 is provided on one side of the clamping plate 40 for placing a filter cloth. Supporting cloths 43 are fixedly connected to opposite sides of the two first fixing airbags 29. Specifically, given the large number of bacteria in the air, the ventilation mechanism 13 prevents bacteria from contacting the femoral artery puncture site when pressure is applied, reducing the risk of infection. More specifically, when the two first fixing airbags 29 are fixed to the leg, the pressure on the skin caused by the two first fixing airbags 29 can cause discomfort and impaired blood flow. The supporting cloths 43 support the skin between the two first fixing airbags 29, making the patient more comfortable and ensuring smooth blood flow.

[0044] like Figure 1 As shown, an elastic cloth 48 is fixedly connected to the side where the lower shell 3 is hinged to the upper shell 4. This ensures that when the leg is placed on top of the lower shell 3 and the upper shell 4 is about to be closed, the elastic cloth 48 prevents the leg muscles from being pinched during the process of closing the lower shell 3 and the upper shell 4, thus improving the safety of the protector shell 2.

[0045] like Figure 1-3 As shown, a fixing clip 44 is fixedly connected to one side of the upper housing 4. The fixing clip 44 is made of plastic, and a fixing slot 45 is provided on one side of the fixing clip 44. A fixing block 46 is fixedly connected to one side of the lower housing 3. The fixing slot 45 and the fixing block 46 are adapted to each other. A buckle plate 47 is fixedly connected to one side of the fixing clip 44. One side of the fixing clip 44 is adapted to one side of the clamping plate 40. When the upper housing 4 and the lower housing 3 are closed, because the fixing clip 44 is made of plastic, one side of the fixing clip 44... When the side passes through the top of the fixing block 46, it deforms. When the fixing block 46 passes through the fixing slot 45, the fixing card 44 returns to its original position, fixing the upper housing 4 and the lower housing 3. At the same time, the filter cloth is placed inside the placement slot 42 and the clamping plate 40 is covered. When the lower housing 3 and the upper housing 4 are fixed, one side of the fixing card 44 fits against the clamping plate 40 to fix the clamping plate 40. When the lower housing 3 and the upper housing 4 are opened by the buckle plate 47, the clamping plate 40 opens automatically so that the used filter cloth can be discarded.

[0046] The working principle of this invention is as follows: When it is necessary to compress and stop bleeding at the femoral artery puncture site, the lower shell 3 and the upper shell 4 are connected to the patient's thigh, so that the upper shell 4 is at the top of the femoral artery puncture site.

[0047] After the lower housing 3 and the upper housing 4 are connected to the thigh, the pneumatic telescopic rod 9 is manually moved according to the position of the femoral artery puncture site, so that the moving block 7 slides at the bottom of the arc-shaped groove 14, and the two sliding rods 15 slide inside the corresponding sliding grooves 16. When the pneumatic telescopic rod 9 slides to the required position, the position of the compression auxiliary mechanism 11 is adjusted according to the angle of the femoral artery puncture site and the thickness of the leg, so that the moving block 7 rotates at the bottom of the arc-shaped groove 14, and the two sliding rods 15 rotate inside the corresponding sliding grooves 16. After the angle adjustment is completed, the compression air pump 23 is started to initially fix the pneumatic telescopic rod 9. At the same time, the pressure inside the moving block 7 drives the output end of the pneumatic telescopic rod 9 to extend, so that the bottom of the compression auxiliary mechanism 11 gradually fits with the femoral artery puncture site.

[0048] By activating the semiconductor cooling chip 19 inside the pressing assist mechanism 11, heat is dissipated from the top of the semiconductor cooling chip 19. The heat is then transferred to the bottom of the first pressing housing 17, which is in contact with the top of the semiconductor cooling chip 19, through the liquid inside the first pressing housing 17. This promotes local blood circulation at the femoral artery puncture site, increases local nutrient supply, increases local metabolism, and promotes local tissue regeneration and repair, thereby aiding in wound healing.

[0049] Simultaneously, the bottom of the semiconductor cooling chip 19 is cooled, which cools the second pressing housing 20 and the liquid inside the second pressing housing 20 that are in contact with the bottom of the semiconductor cooling chip 19, and transmits the cooling to the area around the femoral artery puncture site. Since the femoral artery puncture is performed at an angle, the skin wound and the femoral artery wound are at a certain angle. This allows the second pressing housing 20 outside the first pressing housing 17 to cool the femoral artery wound while promoting the healing of the skin wound, causing the blood vessels to constrict, reducing bleeding, and accelerating the healing of the femoral artery wound.

[0050] Since the healing process is lengthy, and the leg cannot remain stationary throughout, the limiting air pump 26 is activated. The output of the limiting air pump 26 pressurizes the inside of the first air tube 27, allowing gas to enter the two first fixing airbags 29 through the second air tube 28. Simultaneously, gas enters the fourth air tube 32 through the second telescopic air tube 33, and then enters the two second fixing airbags 30 through the pressing air pump 23 and the third air tube 31. This causes the two first fixing airbags 29 and the two second fixing airbags 30 to expand, fixing the protector housing 2 to the leg and preventing movement of the leg during hemostasis. Furthermore, when the two first fixing airbags 29 are fixing the leg, the pressure on the skin can cause discomfort and impaired blood flow. The support cloth 43 supports the skin between the two first fixing airbags 29, making the patient more comfortable and ensuring smooth blood flow.

[0051] Specifically, during the hemostasis process, when blood flows out of the femoral artery puncture wound, the first pressing housing 17 heats the skin and blood around the femoral artery puncture wound, resulting in a higher temperature for the flowing blood. When the blood comes into contact with the patch-type temperature sensor 21, the patch-type temperature sensor 21 detects a sudden increase in temperature. At this time, the pressing mechanism 8 increases the pressing force to apply pressure to the femoral artery puncture wound. When the temperature decreases, the pressure is stopped to ensure that the femoral artery puncture wound stops bleeding. At the same time, the flowing blood flows into the interior of the sealing groove 22, further sealing the area around the femoral artery puncture wound to prevent bacteria from entering before the wound has healed and to avoid the femoral artery puncture wound from worsening. After the hemostasis is completed, the lower housing 3 and the upper housing 4 are opened by snapping on the buckle 47, and one side of the clamp 40 separates from the side of the fixing card 44. The clamp 40 opens automatically, allowing the used filter cloth to be discarded.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
