Description

Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and in particular to a wearable monitor for the radial artery. Background Art

[0002] After surgery, timely evaluation of the radial artery's function, blood flow status, and related physiological parameters is crucial for the patient's surgical limb safety and complication prevention, and can reduce the incidence of postoperative surgical limb complications.

[0003] Currently, postoperative radial artery monitoring typically relies on traditional equipment and manual detection methods, such as blood oxygen saturation monitors, pulse monitors, and thermometers. However, while these devices can provide certain physiological parameter data, they also have some shortcomings: First, these devices usually require patients to stay still and cooperate, but patients often find it difficult to undergo continuous monitoring due to limited limb movement or pain after surgery. Secondly, most traditional monitoring devices are non-wearable, which makes it impossible for patients to monitor their physiological parameters around the clock during their recovery period.

[0004] To solve the above problems, the invention patent with Chinese patent publication number: CN104188636B provides a pulse wave signal monitoring watch that can manually locate the radial artery. Its wearable design facilitates the monitoring of physiological information such as pulse signals.

[0005] However, in actual applications, we found that the above-mentioned wearable monitor still has certain areas that can be optimized.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: See also Figures 1-6 , a wearable monitor for radial artery, comprising a monitoring body 1, such as Figure 1 As shown, one side of the monitoring body 1 is connected to a fixing belt 1 2, and the other side is connected to a fixing belt 2 3. The end of the fixing belt 2 3 is fixedly connected to a connecting ring 4. After the end of the fixing belt 1 2 passes through the connecting ring 4, it is reversely pasted on itself, so that the monitoring body 1 can be worn and fixed on the radial artery. This design is convenient for quick wearing and simple operation, and can be stably and comfortably fixed on the patient's wrist.

[0024] like Figure 2and Figure 3 As shown, a floating groove 5 is provided at the bottom of the monitoring body 1, and a floating block 6 with a monitoring sensor integrated therein is movably arranged in the floating groove 5. The bottom surface of the floating block 6 is attached to the radial artery, so that the patient's physiological information can be monitored. In this embodiment, the monitoring sensor may include a temperature sensor, an oxygen saturation sensor, a pulse sensor, etc., which are used to monitor the patient's limb temperature, oxygen saturation, pulse rate and strength and other physiological information.

[0025] like Figure 3 As shown, a lower support spring 7 is provided between the top of the floating block 6 and the inner top wall of the floating groove 5, which is used to support the floating block 6 downward so that the bottom surface of the floating block 6 is attached to the radial artery.

[0026] Through the design of the floating groove 5 and the floating block 6, the monitor can ensure that the sensor is always in close contact with the radial artery, ensuring the accuracy of the monitoring data. At the same time, the floating block 6 is supported by the lower support spring 7, which also ensures stability and comfort when worn.

[0027] In order to effectively stop bleeding in the radial artery, the present invention further provides a rod receiving groove 12 and a rod receiving groove 13 on both sides of the inner wall of the floating groove 5. The ends of the rod receiving groove 12 and the rod receiving groove 13 are connected by a side groove 11 provided on the inner wall of the floating groove 5. like Figure 5 and Figure 6 As shown, the slide bar 14 is slidably arranged in the rod receiving groove 12, the side groove 11 and the rod receiving groove 2 13, and is connected to a bandage 15 on one side and a pull rope 19 on the other side. Specifically, the bandage 15 is wound on a winding roller 16, and the winding roller 16 is mounted on a polygonal prism 17. The polygonal prism 17 is rotatably mounted in a roller groove 18. The roller groove 18 is opened inside the monitoring body 1 and is adjacent to the rod receiving groove 12; The pull rope 19 passes through the side groove 11 and the second rod groove 13 and around the guide wheel 20, and is wound on the winding roller 21, which is driven to rotate by the motor 22; In addition, both sides of the bottom of the floating block 6 are formed with arc-shaped surfaces, and the opening positions of the rod receiving groove 12 and the rod receiving groove 2 13 correspond to the positions of the arc-shaped surfaces; Thus, when the motor 22 drives the winding roller 21 to rotate to reel in the drawstring 19, the drawstring 19 pulls the slide bar 14 to move and pull out the bandage 15; when the slide bar 14 first starts to move, it squeezes the curved surface, pushing the floating block 6 upward, thereby causing the pulled bandage 15 to be located at the bottom of the floating block 6. As the bandage 15 is gradually pulled out, it gradually covers the bottom of the floating block 6 until the slide bar 14 moves into the second drawstring slot 13; By covering the bottom surface of the floating block 6 with the bandage 15 and then using the floating block 6 to press on the radial artery, it is possible to achieve the effect of pressing to stop bleeding. When bleeding occurs, the floating block 6 is prevented from directly contacting the bleeding point, which significantly improves the efficiency and safety of stopping bleeding and avoids the risk of infection.

[0028] In the present invention, the guide wheel 20 and the winding roller 21 are rotatably installed in their corresponding inner cavities.

[0029] In order to facilitate the replacement of the bloodstained bandage 15, in the present invention, as Figure 6 As shown, the end of the bandage 15 is connected with a T-shaped plug plate, and the slide rod 14 is provided with a T-shaped slot corresponding to the T-shaped plug plate. In addition, a cover plate can be detachably installed at the side of the monitoring body at a position corresponding to the floating groove 5, the rod-collecting groove 12 and the roller groove 18. When the cover plate is opened, the floating groove 5, the rod-collecting groove 12 and the roller groove 18 can be exposed, so that the winding roller 16 and the bandage 15 can be removed for replacement. The convenient bandage replacement structure greatly improves the convenience and hygiene of equipment maintenance, reduces the risk of infection, and optimizes the user experience.

[0030] Therefore, in this embodiment, not only the real-time and accurate physiological monitoring function is realized, but also an automatic and efficient hemostasis solution is provided. It has multiple advantages such as simple structure, comfortable wearing, high degree of automation, and convenient maintenance. It is particularly suitable for real-time monitoring and rapid hemostasis treatment after radial artery surgery, which improves the quality and efficiency of medical monitoring and nursing, and has good application prospects and significant clinical value.

[0031] Example 2: See also Figure 3 Based on the first embodiment, in this embodiment, the bottom of the monitoring body 1 is further provided with two bottom grooves 23 on both sides of the floating groove 5. Water-absorbing and swellable cotton 24 is provided in the bottom groove 23. A pressure plate 25 is provided on the top of the water-absorbing and swellable cotton 24. An air bag 26 is provided on the top of the pressure plate 25. A force-sensitive sensor 27 is also installed on the inner top wall of the bottom groove 23. The output end of the force-sensitive sensor 27 is electrically connected to the main control board, and the output end of the main control board is electrically connected to the input end of the motor 22. When bleeding occurs at the puncture site, the water-absorbent expandable cotton 24 absorbs blood and expands, and then pushes up the pressure plate 25, and uses the pressure plate 25 to squeeze the airbag 26. The airbag 26 is squeezed and transmits the pressure to the force-sensitive sensor 27. The force-sensitive sensor 27 senses the pressure and transmits the signal to the motor 22 through the main control board to control the operation of the motor 22. Therefore, when bleeding occurs, the bandage 15 can be automatically covered on the bottom of the floating block 6, so as to achieve the purpose of using the bandage 15 to press and stop bleeding when bleeding occurs.

[0032] Further, such as Figure 2As shown, the airbag 26 is connected to the vertical slot 9 on the inner top wall of the floating slot 5 through the air pipe 28 and the connecting pipe 29. A movable plate 8 is movably arranged in the vertical slot 9. Two support springs 10 are fixedly arranged between the top of the movable plate 8 and the inner top wall of the vertical slot 9, and the top end of the lower support spring 7 is arranged at the bottom of the movable plate 8. In this way, the floating block 6 is supported downward by the lower support spring 7 and the second support spring 10 at the same time; when bleeding occurs and the airbag 26 is squeezed, the gas therein will be filled into the vertical groove 9 through the trachea 28 and the connecting pipe 29, and push the movable plate 8 downward. By utilizing the downward pressure of the movable plate 8, the downward pressure of the floating block 6 can be further increased to achieve more effective compression to stop bleeding.

[0033] Example 3: See also Figure 1-Figure 3 、 Figure 7 On the basis of the first or second embodiment, in this embodiment, side grooves are further provided on both sides of the bottom of the monitoring body 1, and a piston plate 31 is movably provided in the side groove. An adhesive pad 32 is fixedly installed at the bottom of the piston plate 31, and a support spring 35 is provided between the top of the piston plate 31 and the inner top wall of the side groove. In addition, a connecting rope 30 is further connected to the top of the piston plate 31, and the end of the connecting rope 30 extends to the outside of the monitoring body 1 and is connected to the fixing belt; In addition, a force sensitive sensor 2 37 is fixedly mounted on the inner top wall of the side groove; The monitoring body 1 can be attached and fixed to the radial artery using the adhesive pad 32, and the monitoring body 1 can be further tied and fixed to the radial artery using the fixing belt 1 2 and the fixing belt 2 3; When a limb swells, the limb will tighten the fixing belt 1 2 and the fixing belt 2 3, and then the fixing belt 1 2 and the fixing belt 2 3 will pull the piston plate 31 through the connecting rope 30. When the piston plate 31 is pulled, the adhesive pad 32 will be separated from the skin, and the support spring 35 will be compressed, and the force-sensitive sensor 2 37 will be triggered. The pressure monitored by the force-sensitive sensor 2 37 can be used to determine the degree of limb swelling; by separating the adhesive pad 32 from the skin, the monitoring body 1 can better adapt to the swollen limb.

[0034] In this embodiment, Figure 7 As shown, an annular support plate 33 is fixedly mounted on the inner wall of the side groove, an electromagnet 1 34 is fixedly mounted on the annular support plate 33, and an electromagnet 2 36 is fixedly mounted on the inner top wall of the side groove; In the normal wearing state, the electromagnet 2 36 is energized to enable the piston plate 31 to move upward to expand the entire fixing band. Conversely, the electromagnet 2 36 is de-energized to restore the entire fixing band to its original size. When the limb is swollen, the electromagnet 34 is energized to make the piston plate 31 move downward actively to reduce the size of the entire fixing band. On the contrary, the electromagnet 34 is de-energized to restore the entire fixing band to its original size. Thus, by changing the size of the fixing strap, the wrist can be hugged cyclically, forming a controllable pressure fluctuation around the wrist, promoting the return of blood and lymph, and avoiding or reducing swelling; this pressure fluctuation control can be performed intermittently during normal wear, or cyclically when the limb is swollen.

[0035] Further, such as Figure 3 and Figure 7 As shown, one side of the side groove is connected to an air inlet pipe 38, on which a one-way air inlet valve is provided, and the other side of the side groove is connected to an exhaust pipe 39, on which a one-way air outlet valve is provided, and the end of the exhaust pipe 39 is open on the inner bottom wall of the monitoring body 1; When the piston plate 31 moves downward, external air can be inhaled through the air inlet pipe 38; when the piston plate 31 moves upward, air can be discharged through the exhaust pipe 39, and the discharged air flows out from the inner bottom wall of the monitoring body 1, thereby accelerating the air circulation at the wearing point of the monitoring body 1 and improving the patient's comfort.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
