Description

Technical Field

[0001] The present invention belongs to the field of medical assistance technology, and in particular relates to an exoskeleton assistive device. Background Art

[0002] Cardiopulmonary resuscitation is a vital first aid technique specifically used to respond to emergencies of cardiac arrest and respiratory arrest. This technology simulates the heart's pumping function by performing rhythmic compressions on the chest, thereby forming a temporary artificial circulatory system. The purpose of this is to maintain blood circulation and ensure that oxygen and nutrients can continue to be delivered to the body's vital organs, especially the brain and heart. In general, cardiopulmonary resuscitation is a comprehensive first aid measure that covers a variety of techniques and methods, aimed at saving lives as much as possible and reducing the serious consequences caused by cardiac and respiratory arrest.

[0003] Currently, most of the common CPR assisted compression devices on the market rely on electricity. Although this design can provide relatively convenient compression force in most cases, it will become unusable in the event of power outages or unstable power supply. This will affect the scope of application in emergency situations, and its practicality is insufficient and needs to be improved.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and an exoskeleton assistive device is provided in order to achieve the purpose of having more practical value. Summary of the Invention

[0005] The present invention mainly aims to solve the technical problems existing in the above-mentioned prior art and provides an exoskeleton assistive device.

[0006] The above technical problem of the present invention is mainly solved by the following technical solution: an exoskeleton assistive device includes a first base and a second base, wherein a protective pad is fixedly installed between the first base and the second base;

[0007] An alarm mechanism is fixedly mounted on the surface of the first base;

[0008] The alarm mechanism includes a blood oxygen detection device, a patch is provided on the surface of the blood oxygen detection device, a control and power supply unit is provided on the side wall of the first base, a first alarm indicator light is fixedly installed on the upper end of the first base, and a second alarm indicator light is fixedly installed on the upper end of the second base. First damping ball hinges are symmetrically fixedly installed on the opposite end faces of the first base and the second base, a gas pressure strut is fixedly installed at the hinge joint of each of the first damping ball hinges, a second damping ball hinge is fixedly installed at the piston of each of the gas pressure struts, and a fixing plate is fixedly installed between the hinge joints of the two groups of the second damping ball hinges, a friction plate is fixedly installed on the upper end of the fixing plate, and a silicone layer is fixedly installed on the lower end of the fixing plate.

[0009] Preferably, limiting grooves are provided inside the two first bases and the second base, and screw rods are rotatably installed inside the two limiting grooves. Both screw rods are partially exposed above the first base and the second base, and first transmission blocks are slidably installed inside the two limiting grooves.

[0010] Preferably, a through slot is provided inside each of the two first transmission blocks, the diameter of each of the through slots is larger than the thread diameter of the screw rod, connecting rods are fixedly mounted on the side walls of each of the two first transmission blocks, and the two connecting rods are located on both sides of the fixed plate.

[0011] Preferably, the two connecting rods are fixedly installed on the fixed plate, the second transmission blocks are slidably installed inside the two limit grooves, the two second transmission blocks are located below the first transmission block, the two second transmission blocks are threadedly installed on the screw rod, and the two second transmission blocks are embedded with limit switches, and the two limit switches are spring-pressed type.

[0012] Preferably, both of the second transmission blocks are partially exposed outside the second transmission block, and both of the side walls of the second transmission blocks are fixedly mounted with pointers, and both of the opposite end faces of the first base and the second base are fixedly mounted with scales, and both of the pointers are adapted to the scales, and the blood oxygen detection device is adapted to the second alarm indicator light.

[0013] Preferably, the limit switch is adapted to the first alarm indicator light, and the first transmission block is adapted to the limit switch.

[0014] The present invention has the beneficial effects:

[0015] In the present invention, by pressing the friction plate downward, the friction plate generates a radial force on the fixed plate to drive the silicone layer to move downward toward the patient's chest cavity. When the fixed plate is squeezed downward, the radial force generated will cause the hinge joint of the second damping ball hinge to adaptively rotate on the second damping ball hinge. At the same time, the piston of the gas pressure strut will adaptively extend according to the amplitude of the downward movement of the fixed plate, and the hinge joint of the first damping ball hinge will also adaptively rotate within the first damping ball hinge, thereby completing auxiliary pressing of the patient. Since the chest cavity is an irregular arc surface, by making the friction plate into a plane, it can achieve a more labor-saving effect compared to indirect pressing of the staff's chest cavity, reduce the labor burden and improve practicality.

[0016] In the present invention, by arranging the first transmission block and the connecting rod on both sides of the fixed plate, and limiting the first transmission block by the limiting groove, when the staff presses the fixed plate, the first transmission block will be driven by the connecting rod to slide inside the limiting groove, so that the fixed plate will perform linear movement up and down in the vertical direction to assist cardiopulmonary resuscitation pressing on the patient's chest cavity, thereby improving stability.

[0017] In the present invention, by arranging a second transmission block on the screw rod and adjusting it in advance, when the staff presses the friction plate to drive the fixed plate to perform cardiopulmonary resuscitation on the chest cavity of the person being resuscitated, the staff can use full force to press each time, avoiding the worry of excessive pressing causing damage to the patient's chest cavity and ineffective pressing caused by too little force, helping the staff to keep the force and depth of each compression consistent, ensuring that each compression is effective; in surgery or some interventional operations, it can eliminate small muscle tremors, reduce shaking, increase the precision of cardiopulmonary resuscitation operations, improve the success rate of cardiopulmonary resuscitation, increase the precision of other clinical operations, and improve practicality.

[0018] In the present invention, a screw rod is arranged inside the limit groove, so that the staff can first rotate the screw rod according to the chest thickness of the person undergoing cardiopulmonary resuscitation and the required chest compression depth, so that the two screw rods rotate in the limit groove and undergo threaded transmission with the second transmission block, thereby causing the two second transmission blocks to move upward on the screw rod, thereby driving the data pointed to by the pointer on the scale to change steplessly. When the pointer moves to the end of the compression depth of the chest cavity of the person undergoing cardiopulmonary resuscitation, the staff can stop rotating the screw rod, so that the device can adapt to patients with different chest cavity thicknesses, thereby improving the overall applicability of the device.

[0019] In the present invention, when the staff presses multiple times, the blood oxygen saturation in the staff's body will change. When performing physical activities, the body's demand for oxygen increases. If the blood oxygen saturation decreases, it may indicate that the body cannot meet the current oxygen demand and is in a state of fatigue or hypoxia. Therefore, when the blood oxygen saturation drops to a certain level, the blood oxygen detection device will send a signal to control the second alarm indicator light to flash, which can facilitate the staff to adjust their status or change people in time, improve the continuity of work, and further improve the rescue efficiency.

[0020] In summary, the present invention has various application scenarios and can be applied to various other surgical operations to improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0031] Example: An exoskeleton assistive device, such as Figures 1-8 As shown, it includes a first base 11 and a second base 12, and a pad 13 is fixedly installed between the first base 11 and the second base 12;

[0032] An alarm mechanism is fixedly mounted on the surface of the first base 11;

[0033] The alarm mechanism includes a blood oxygen detection device 14, a patch is provided on the surface of the blood oxygen detection device 14, and a control and power supply unit 15 is provided on the side wall of the first base 11. When the staff presses it multiple times, the blood oxygen saturation in the staff's body will change. When performing physical activities, the body's demand for oxygen increases. If the blood oxygen saturation decreases, it may indicate that the body cannot meet the current oxygen demand and is in a state of fatigue or hypoxia. Therefore, when the blood oxygen saturation drops to a certain level, the blood oxygen detection device 14 will send a signal to control the second alarm indicator light 17 to flash, which can facilitate the staff to adjust their status or change people in time, improve the continuity of work, and further improve the rescue efficiency.

[0034] A first alarm indicator light 16 is fixedly installed on the upper end of the first base 11, a second alarm indicator light 17 is fixedly installed on the upper end of the second base 12, and first damping ball hinges 18 are symmetrically fixedly installed on the opposite end surfaces of the first base 11 and the second base 12. A gas pressure strut 19 is fixedly installed at the hinge joint of each first damping ball hinge 18, and a second damping ball hinge 21 is fixedly installed at the piston of each gas pressure strut 19. A fixing plate 22 is fixedly installed between the hinge joints of the two groups of second damping ball hinges 21, a friction plate 23 is fixedly installed on the upper end of the fixing plate 22, and a silicone layer 24 is fixedly installed on the lower end of the fixing plate 22. By pressing the friction plate 23 downward, the friction plate 23 produces a friction on the fixing plate 22. A radial force drives the silicone layer 24 to move downward toward the patient's chest cavity. When the fixing plate 22 is squeezed downward, the radial force generated will cause the hinge joint of the second damping ball hinge 21 to adaptively rotate on the second damping ball hinge 21. At the same time, the piston of the gas pressure strut 19 will be adaptively extended according to the amplitude of the downward movement of the fixing plate 22, and the hinge joint of the first damping ball hinge 18 will also be adaptively rotated within the first damping ball hinge 18, thereby completing the auxiliary compression of the patient. Since the chest cavity is an irregular arc surface, by making the friction plate 23 a plane, it can achieve a more labor-saving effect compared to indirect compression of the staff's chest cavity, reduce the labor burden and improve practicality.

[0035] A limiting groove 25 is provided inside the two first bases 11 and the second base 12, and a screw rod 26 is rotatably installed inside the two limiting grooves 25. The two screw rods 26 are partially exposed above the first base 11 and the second base 12, and a first transmission block 27 is slidably installed inside the two limiting grooves 25. A through groove 28 is provided inside the two first transmission blocks 27, and the diameter of the two through grooves 28 is larger than the thread diameter of the screw rod 26. A connecting rod 29 is fixedly installed on the side walls of the two first transmission blocks 27, and the two connecting rods 29 are located on both sides of the fixed plate 22. By arranging the first transmission blocks 27 and the connecting rod 29 on both sides of the fixed plate 22, and limiting the first transmission blocks 27 by the limiting groove 25, when the staff presses the fixed plate 22, the first transmission blocks 27 will be driven by the connecting rod 29 to slide inside the limiting groove 25, so that the fixed plate 22 will perform linear movement up and down in the vertical direction to assist cardiopulmonary resuscitation compression on the patient's chest cavity, thereby improving stability.

[0036] The two connecting rods 29 are fixedly installed on the fixed plate 22, and the second transmission blocks 31 are slidably installed inside the two limit grooves 25. The two second transmission blocks 31 are located below the first transmission block 27, and the two second transmission blocks 31 are threadedly installed with the screw rod 26. By arranging the screw rod 26 inside the limit groove 25, the staff can first rotate the screw rod 26 according to the chest thickness of the person undergoing cardiopulmonary resuscitation and the required chest compression depth, so that the two screw rods 26 rotate in the limit groove 25 and are threadedly transmitted with the second transmission block 31, thereby causing the two second transmission blocks 31 to move upward on the screw rod 26, thereby driving the data pointed to by the pointer 33 on the scale 34 to change steplessly. When the pointer 33 moves to the end of the compression depth of the chest of the person undergoing cardiopulmonary resuscitation, the staff can stop rotating the screw rod 26, so that the device can adapt to patients with different chest thicknesses, thereby improving the overall applicability of the device.

[0037] The two second transmission blocks 31 are both embedded with limit switches 32. The two limit switches 32 (limit switches 32 are a commonly used electrical control component, mainly used to detect the movement position of mechanical equipment and send signals at specific positions to control the operation of the equipment) are all spring-pressed. The two second transmission blocks 31 are partially exposed outside the second transmission blocks 31. Pointers 33 are fixedly installed on the side walls of the two second transmission blocks 31. Scales 34 are fixedly installed on the opposite end surfaces of the first base 11 and the second base 12. The two pointers 33 are adapted to the scales 34. By setting a The second transmission block 31 is set and adjusted in advance so that when the staff presses the friction plate 23 to drive the fixed plate 22 to perform cardiopulmonary resuscitation on the chest of the person being pressed by cardiopulmonary resuscitation, the staff can use full force each time to press, avoiding the worry that excessive pressing may cause damage to the patient's chest cavity and ineffective pressing caused by insufficient force, helping the staff to keep the force and depth of each compression consistent, ensuring that each compression is effective. In surgery or some interventional operations, it can eliminate small muscle tremors, reduce shaking, increase the precision of cardiopulmonary resuscitation operations, improve the success rate of cardiopulmonary resuscitation, and improve practicality.

[0038] The blood oxygen detection device 14 is adapted to the second alarm indicator light 17, the limit switch 32 is adapted to the first alarm indicator light 16, and the first transmission block 27 is adapted to the limit switch 32. By setting the first alarm indicator light 16, after the staff presses into place, the first alarm indicator light 16 can emit light in time, so that the staff can timely contact the pressure on the friction plate 23 to reset the pneumatic strut 19, which is beneficial to the repeatability of cardiopulmonary resuscitation pressing and further improves practicality.

[0039] Principle of the present invention:

[0040] In the first step, when the device needs to be used for assisted cardiopulmonary resuscitation, the staff can first adjust the second transmission block 31 according to the chest thickness of the person undergoing cardiopulmonary resuscitation and the required chest compression depth. The staff can first synchronously rotate the screw rod 26, so that the two screw rods 26 rotate in the limit groove 25 and transmit threaded transmission to the second transmission block 31, thereby causing the two second transmission blocks 31 to move upward on the screw rod 26. The movement of the second transmission block 31 will actively slide with the limit groove 25, thereby causing the data pointed by the pointer 33 on the scale 34 to change. When the pointer 33 moves to the end of the chest compression depth of the person undergoing cardiopulmonary resuscitation, the staff can stop rotating the screw rod 26.

[0041] In the second step, the staff can then turn on the control and power supply unit 15 so that the control and power supply unit 15 can power the blood oxygen detection device 14. After the power supply is completed, the staff can turn on the blood oxygen detection device 14 and stick the patch of the blood oxygen detection device 14 on the staff's wrist. Then the staff can put both hands on the friction plate 23 and press down, so that the friction plate 23 generates a radial force on the fixed plate 22 to drive the silicone layer 24 to move downward toward the patient's chest cavity. At the same time, due to the limitation of the first transmission block 27 and the connecting rod 29 on the fixed plate 22, the fixed plate 22 will perform linear movement up and down in the vertical direction. Moreover, when the fixed plate 22 is squeezed downward, the radial force generated will cause the second resistance The hinged joint of the damping ball hinge 21 adaptively rotates on the second damping ball hinge 21. At the same time, the piston of the gas strut 19 (the gas strut 19, also known as the gas spring, is an elastic element using gas as the working medium and can reset itself without an air pump) will adaptively extend according to the downward movement of the fixed plate 22. Moreover, the hinged joint of the first damping ball hinge 18 (the first damping ball hinge 18 and the second damping ball hinge 21 are connecting components with a damping function, mainly used to achieve multi-angle connection and relative movement between two objects, and provide a certain resistance during movement to control the speed and stability of the movement) will also adaptively rotate within the first damping ball hinge 18.

[0042] In the third step, when the fixing plate 22 moves toward the patient's chest compression position, it will drive the first transmission block 27 and the connecting rod 29 to move, so that the first transmission block 27 slides inside the limit groove 25. When the bottom surface of the first transmission block 27 is pressed against the limit switch 32 inside the limit groove 25, the fixing plate 22 cannot be pressed down due to the limitation of the second transmission block 31 by the thread of the screw rod 26. At the same time, the silicone layer 24 will accurately press the patient's chest. When the first transmission block 27 contacts the limit switch 32, the limit switch 32 is squeezed by the first transmission block 27. At this time, the limit switch 32 will send a signal to the first alarm indicator light 16, so that the first alarm indicator light 16 emits a light, so that the staff can release the pressure on the friction plate 23 after observation. At the same time, the piston of the gas pressure strut 19 will automatically reset due to lack of pressure, so that the piston of the gas pressure strut 19 drives the fixing plate 22 to reset to its original position.

[0043] In the fourth step, after the staff presses multiple times, the blood oxygen saturation in the staff's body will change. When performing physical activities, the body's demand for oxygen increases. If the blood oxygen saturation decreases, it may indicate that the body cannot meet the current oxygen demand and is in a state of fatigue or hypoxia. Therefore, when the blood oxygen saturation drops to a certain level, the blood oxygen detection device 14 (the blood oxygen detection device 14 uses optical technology to measure blood oxygen saturation. It uses two different wavelengths of light (generally red light and infrared light) to irradiate specific parts of the human body. Since the oxygenated hemoglobin and reduced hemoglobin in the blood have different absorption characteristics for these two types of light, by detecting the intensity change of the transmitted or reflected light, the ratio of oxygenated hemoglobin to total hemoglobin in the blood can be calculated, thereby obtaining the blood oxygen saturation value) will send a signal to control the second alarm indicator light 17 to flash, which can facilitate the staff to adjust the status in time.

[0044] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention are deemed to fall within the scope of protection of the present invention.
