Description

Technical Field

[0001] This invention relates to the field of medical testing technology, specifically to a cardiovascular disease testing device. Background Technology

[0002] Cardiovascular disease is a serious threat to people's health and life. It mainly includes coronary heart disease, stroke and peripheral vascular disease. Cardiovascular disease is the number one killer of human health and the number one health killer in China. Among many physiological signals, electrocardiogram (ECG) signals are an important means of detecting heart disease, especially cardiovascular diseases that are sudden and random. The morphology, intensity and rate of the pulse wave reflect important physiological and pathological information of the human cardiovascular system.

[0003] However, existing cardiovascular disease detection devices do not have the function of assisting patients' breathing, cannot provide oxygen when patients have cardiovascular disease symptoms, cannot use the weight of the patient's arm to help lift the base of the tongue to keep the airway open, the devices are difficult to use, have poor cushioning capacity, and cannot avoid abrading the patient's mouth when using the devices. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: A cardiovascular disease detection device according to this invention includes a strip-shaped flexible body and a pulse acquisition device disposed on one side of the strip-shaped flexible body. One side of the strip-shaped flexible body is provided with:

[0005] A hemispherical block, and an anti-slip groove formed on the outer side of the hemispherical block, wherein pressure sensors are uniformly installed on one side of the inner wall of the anti-slip groove;

[0006] A ventilation channel is provided on one side of the hemispherical block and extends through the hemispherical block. A partition plate is provided inside the ventilation channel. An air pump is fixedly connected to the side of the partition plate near the strip-shaped flexible body. The output end of the air pump extends through the partition plate and to the outside of the partition plate. A processor is fixedly connected to the top of the inner side of the ventilation channel. The pressure sensor and the air pump are electrically connected to the processor through wires. This can assist in supplying air when the patient has cardiovascular disease symptoms, so as to prevent the patient from not being able to breathe normally and get enough oxygen.

[0007] An extension plate is installed inside the ventilation slot, and a storage slot is opened on the top of the extension plate. A fiber rope is fixedly connected to one side of the inner wall of the storage slot. The end of the fiber rope away from the extension plate passes through the partition plate and is fixedly connected to the strip-shaped flexible body. A guide rod is fixedly connected between the two sides of the inner wall of the ventilation slot at the end away from the strip-shaped flexible body. The fiber rope is slidably connected to the guide rod.

[0008] Preferably, the hemispherical block has symmetrically inclined grooves on one side near the strip-shaped flexible body. An electrically controlled telescopic rod is fixedly connected to one side of the inner wall of the inclined groove. The electrically controlled telescopic rod is electrically connected to the processor through a wire. A circular groove adapted to the electrically controlled telescopic rod is formed on one side of the strip-shaped flexible body. This allows for the control of the separation and splicing of equipment components as needed, improving the flexibility of equipment use. It can utilize the grooves in the equipment structure and control the separation of equipment components during pulling to prevent the hemispherical block from being pulled away from the patient's mouth, ensuring that the equipment can assist breathing through the patient's mouth and lift the base of the tongue to ensure the patient's airway is unobstructed, thus improving the reliability of the equipment.

[0009] Preferably, an extension groove is provided on one side of the extension plate, and a buffer plate is installed inside the extension groove. One end of the buffer plate extends to the outside of the extension groove, which can use the patient's own arm weight to help lift the patient's tongue base to keep the airway open without the need for conscious control by the patient, thus reducing the difficulty of using the device.

[0010] Preferably, a slider is slidably connected to the bottom inner side of the extension groove, the buffer plate is fixedly connected to the slider, a buffer spring is fixedly connected to the side of the slider away from the buffer plate, and the end of the buffer spring away from the slider is fixedly connected to the inner wall of the extension groove, which improves the buffering capacity of the device and can prevent the device from rubbing the patient's oral cavity when lifting the patient's tongue root.

[0011] Preferably, a control groove is formed on the side of the strip-shaped flexible body near the hemispherical block. An arc-shaped plate is fixedly connected to the middle of the bottom of the inner side of the control groove. Extended arc plates are installed on both sides of the arc-shaped plate inside the control groove. A first protrusion is fixedly connected to both ends of the arc-shaped plate. A slot is formed on the side of the extended arc plate near the arc plate. A second protrusion is fixedly connected to the side of the extended arc plate away from the arc plate. A traction rope is installed on one side of the arc plate. The traction rope passes through the arc plate and is connected to the extended arc plate. A motor is fixedly connected to the outer side of the strip-shaped flexible body near the control groove. The traction rope is fixedly connected to the output end of the motor. An elastic rope is fixedly connected to the side of the extended arc plate away from the arc plate. The end of the elastic rope away from the extended arc plate is fixedly connected to the inner wall of the control groove. This allows the rigidity of the strip-shaped flexible body to be controlled as needed, making it convenient to wear the device on the patient's wrist and fix it, thus improving the ease of use of the device.

[0012] This invention provides a cardiovascular disease detection device. It has the following beneficial effects:

[0013] 1. This cardiovascular disease detection device is worn on the patient's wrist via a flexible strip-shaped body. A pulse acquisition device performs real-time detection of cardiovascular diseases. When the patient feels unwell, they place the hemispherical block in their mouth, biting down with their teeth into the anti-slip groove. As the hemispherical block moves towards the patient's mouth, the arm is raised. Due to the weight of the arm, the hemispherical block is pulled away from the patient. During this pulling process, the teeth compress the inner wall of the anti-slip groove and the pressure sensor. After the pressure sensor is compressed, the signal is transmitted to the processor. The processor controls the air pump to expel air, and fresh air continuously flows through the ventilation slot into the patient's mouth. This can assist in supplying air when the patient experiences cardiovascular disease symptoms, preventing the patient from being unable to breathe normally and receiving sufficient oxygen.

[0014] 2. This cardiovascular disease detection device extends into a circular groove via an electrically controlled telescopic rod. The hemispherical block and the strip-shaped flexible body are fixed in place by the telescopic rod. When the teeth press against the inner wall of the anti-slip groove and the pressure sensor, the pressure sensor transmits a signal to the processor. The processor controls the telescopic rod to retract. Once the telescopic rod is fully inside the inclined groove, it no longer holds the strip-shaped flexible body. The patient's arm weight causes the strip-shaped flexible body to move towards the ground. As the patient's arm moves, the strip-shaped flexible body moves along with the extension plate via a fiber rope. The extension plate is pulled towards the patient's mouth by the fiber rope until it enters the patient's mouth and lifts the base of the tongue. This device utilizes the patient's arm weight to assist in lifting the base of the tongue and maintain an open airway, without requiring conscious control from the patient, thus reducing the difficulty of using the device.

[0015] 3. When the cardiovascular disease detection device is moved towards the patient's mouth by the extension plate being pulled by the fiber rope, the buffer plate first contacts the patient's tongue. After being blocked by the patient's tongue, the buffer plate pushes the slider to squeeze the buffer spring for cushioning. Then, the buffer plate lifts the patient's tongue to keep the patient's airway open, which improves the device's cushioning capacity and can prevent the device from rubbing the patient's oral cavity when lifting the base of the tongue.

[0016] 4. This cardiovascular disease detection device extends into the circular groove via an electrically controlled telescopic rod. The hemispherical block and the strip-shaped flexible body are fixed in place by the telescopic rod. After the teeth squeeze the inner wall of the anti-slip groove and the pressure sensor, the pressure sensor transmits a signal to the processor. The processor controls the telescopic rod to retract. Once the telescopic rod is fully inside the inclined groove, it no longer holds the strip-shaped flexible body. At this point, the strip-shaped flexible body and the hemispherical block separate. This allows for the control of the separation and splicing of equipment components as needed, improving the flexibility of equipment use.

[0017] 5. This cardiovascular disease detection device works by having the patient place a hemispherical block in their mouth, with their teeth biting into the anti-slip groove. As the arm moves towards the patient's mouth, it is raised, and the arm's own weight pulls the hemispherical block away from the patient. During this pulling process, the teeth compress the inner wall of the anti-slip groove and the pressure sensor. The processor controls the retraction of the electrically controlled telescopic rod. Once the electrically controlled telescopic rod is fully inside the inclined groove, it no longer jams the strip-shaped flexible body. At this point, the strip-shaped flexible body and the hemispherical block separate. The patient's own weight then moves the strip-shaped flexible body towards the ground, and the weight of the patient's arm no longer pulls on the hemispherical block. By utilizing the grooves in the device structure and controlling the separation of device components during pulling, the hemispherical block is prevented from being pulled out of the patient's mouth. This ensures that the device can assist breathing through the patient's mouth and lift the base of the tongue to ensure an unobstructed airway, thus improving the reliability of the device.

[0018] 6. This cardiovascular disease detection device uses an elastic rope to pull an extension arc plate away from the curved plate. A gap exists between the extension arc plate and the curved plate. The strip-shaped flexible body, positioned in this gap, can be twisted and deformed to change its shape. When the strip-shaped flexible body is twisted and placed on the patient's wrist, the motor starts and winds the traction rope. The traction rope is pulled away from the curved plate, pulling the extension arc plate closer to it. The elastic rope is stretched and deformed by the extension arc plate, causing the first and second protrusions to engage in the slots. At this point, the curved plate and the extension arc plate are joined together as a single unit. The strip-shaped flexible body is restricted in its position by the curved plate and the extension arc plate and cannot be twisted or deformed. The strip-shaped flexible body is thus secured to the patient's wrist and cannot be removed. The device's rigidity can be controlled as needed, facilitating its placement and fixation on the patient's wrist, thus improving ease of use. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] Example 1

[0030] Please see Figures 1-5 The present invention provides a technical solution: a cardiovascular disease detection device, comprising a strip-shaped flexible body 1, and a pulse acquisition device 2 disposed on one side of the strip-shaped flexible body 1, wherein one side of the strip-shaped flexible body 1 is provided with:

[0031] The hemispherical block 3 and the anti-slip groove 4 opened on the outside of the hemispherical block 3, with pressure sensors 5 evenly installed on one side of the inner wall of the anti-slip groove 4;

[0032] Ventilation slot 6 is located on one side of hemispherical block 3 and extends through hemispherical block 3. A partition plate 7 is located inside ventilation slot 6. An air pump 8 is fixedly connected to the side of partition plate 7 near the strip-shaped flexible body 1. The output end of air pump 8 extends through partition plate 7 and to the outside of partition plate 7. A processor 9 is fixedly connected to the top of the inner side of ventilation slot 6. Pressure sensor 5 and air pump 8 are both electrically connected to processor 9 through wire 10.

[0033] An extension plate 11 is installed inside the ventilation slot 6, and a storage slot 12 is opened on the top of the extension plate 11. A fiber rope 13 is fixedly connected to one side of the inner wall of the storage slot 12. The end of the fiber rope 13 away from the extension plate 11 passes through the partition plate 7 and is fixedly connected to the strip-shaped flexible body 1. A guide rod 14 is fixedly connected between the two sides of the inner wall of the ventilation slot 6 at the end away from the strip-shaped flexible body 1. The fiber rope 13 is slidably connected to the guide rod 14.

[0034] The hemispherical block 3 has symmetrically opened inclined grooves 15 on one side near the strip-shaped flexible body 1. An electrically controlled telescopic rod 16 is fixedly connected to one side of the inner wall of the inclined groove 15. The electrically controlled telescopic rod 16 is electrically connected to the processor 9 through the wire 10. A circular groove 17 adapted to the electrically controlled telescopic rod 16 is opened on one side of the strip-shaped flexible body 1.

[0035] In use, the flexible strip 1 is worn on the patient's wrist, and the pulse acquisition device 2 performs real-time detection of cardiovascular diseases. When the patient feels unwell, the patient puts the hemispherical block 3 into their mouth, and their teeth bite into the anti-slip groove 4. As the hemispherical block 3 moves towards the patient's mouth, the arm is raised. Due to the weight of the arm itself, the hemispherical block 3 is pulled away from the patient. During the pulling process, the teeth squeeze the inner wall of the anti-slip groove 4 and the pressure sensor 5. After the pressure sensor 5 is squeezed, the signal is transmitted to the processor 9. The processor 9 controls the air pump 8 to spray air, and fresh air continuously moves into the patient's mouth through the ventilation groove 6. This can assist in supplying air when the patient has symptoms of cardiovascular disease, preventing the patient from being unable to breathe normally and getting enough oxygen.

[0036] After the electrically controlled telescopic rod 16 extends into the circular groove 17, the hemispherical block 3 and the strip-shaped flexible body 1 are fixed in place by the electrically controlled telescopic rod 16 as a whole. After the teeth squeeze the inner wall of the anti-slip groove 4 and the pressure sensor 5, the pressure sensor 5 transmits the signal to the processor 9. The processor 9 controls the electrically controlled telescopic rod 16 to retract. After the electrically controlled telescopic rod 16 is fully inserted into the inclined groove 15, it no longer holds the strip-shaped flexible body 1. At this time, the strip-shaped flexible body 1 and the hemispherical block 3 separate. It can control the separation and splicing between equipment components as needed, which improves the flexibility of equipment use. Due to the weight of the patient's arm, the strip-shaped flexible body 1 moves towards the ground. As the patient's arm moves, the strip-shaped flexible body 1 moves through the fiber rope 13 to pull the extension plate 11. The extension plate 11 is pulled by the fiber rope 13 towards the patient's mouth until the extension plate 11 enters the patient's mouth and lifts the patient's tongue root. It can use the weight of the patient's arm to help lift the patient's tongue root and keep the airway open. It does not require the patient's conscious control and reduces the difficulty of using the equipment.

[0038] Please see Figures 1-8The present invention provides a technical solution: based on embodiment 1, an extension groove 18 is provided on one side of the extension plate 11, a buffer plate 19 is installed inside the extension groove 18, and one end of the buffer plate 19 extends to the outside of the extension groove 18.

[0039] A slider 20 is slidably connected to the bottom inner side of the extension groove 18. A buffer plate 19 is fixedly connected to the slider 20. A buffer spring 21 is fixedly connected to the side of the slider 20 away from the buffer plate 19. The end of the buffer spring 21 away from the slider 20 is fixedly connected to the inner wall of the extension groove 18.

[0040] A control groove 22 is provided on one side of the strip-shaped flexible body 1 near the hemispherical block 3. An arc plate 23 is fixedly connected to the middle position of the bottom of the inner side of the control groove 22. Extended arc plates 24 are installed on both sides of the arc plate 23 inside the control groove 22.

[0041] Both ends of the arc plate 23 are fixedly connected with a first protrusion 25, and the side of the extended arc plate 24 near the arc plate 23 is provided with a slot 26, and the side of the extended arc plate 24 away from the arc plate 23 is fixedly connected with a second protrusion 27.

[0042] A traction rope 28 is installed on one side of the arc plate 23. The traction rope 28 passes through the arc plate 23 and is connected to the extension arc plate 24.

[0043] A motor 29 is fixedly connected to the outer side of the strip-shaped flexible body 1 near the control groove 22, and the traction rope 28 is fixedly connected to the output end of the motor 29.

[0044] An elastic rope 30 is fixedly connected to the side of the extended arc plate 24 away from the arc plate 23, and the end of the elastic rope 30 away from the extended arc plate 24 is fixedly connected to the inner wall of the control groove 22.

[0045] After passing through the arc-shaped plate 23, the traction rope 28 is fixedly connected to the extended arc plate 24 that is furthest away from the arc-shaped plate 23. The extended arc plate 24 that is furthest away from the arc-shaped plate 23 and the extended arc plate 24 between the arc-shaped plate 23 are passed through by the traction rope 28 and are slidably connected to the traction rope 28.

[0046] When in use, when the extension plate 11 is pulled towards the patient's mouth by the fiber rope 13, the buffer plate 19 first contacts the patient's tongue. After the buffer plate 19 is blocked by the patient's tongue, it pushes the slider 20 to squeeze the buffer spring 21 for cushioning. Then the buffer plate 19 lifts the patient's tongue to keep the patient's airway open, which improves the buffering capacity of the device and can prevent the device from scratching the patient's oral cavity when lifting the base of the tongue.

[0047] The elastic rope 30 pulls the extension arc plate 24 away from the arc plate 23. There is a gap between the extension arc plate 24 and the arc plate 23. The strip-shaped flexible body 1, located at the gap between the arc plate 23 and the extension arc plate 24, can be twisted and deformed to change its shape. At this time, the strip-shaped flexible body 1 is twisted and placed on the patient's wrist. After the motor 29 starts, it winds the traction rope 28. The traction rope 28 is pulled away from the arc plate 23 and then pulls the extension arc plate 24 closer to the arc plate 23. The elastic rope 30 is stretched and deformed by the extension arc plate 24. The first protrusion 25 and the second protrusion 27 are inserted into the slot 26. At this time, the arc plate 23 and the extension arc plate 24 are spliced ​​into a whole. The strip-shaped flexible body 1 is restricted in position by the arc plate 23 and the extension arc plate 24 and cannot be twisted and deformed. At this time, the strip-shaped flexible body 1 is stuck on the patient's wrist and cannot be removed. The softness and hardness of the strip-shaped flexible body 1 can be controlled as needed, making it convenient to wear the device on the patient's wrist and fix it, thus improving the ease of use of the device.
