Description

Technical Field

[0001] The invention relates to the field of emergency equipment, and in particular to an emergency equipment for coronary heart disease used in cardiovascular medicine. Background Art

[0002] Cardiovascular disease, especially coronary heart disease, is one of the leading causes of death and disability worldwide. Coronary heart disease is a heart disease caused by insufficient blood supply to the coronary arteries, leading to myocardial ischemia, hypoxia or necrosis. Its clinical manifestations are diverse, including angina pectoris, myocardial infarction, arrhythmia and heart failure. In the event of an acute attack of coronary heart disease, timely emergency measures are of great significance to saving patients' lives and reducing complications.

[0003] Traditional emergency treatment for coronary heart disease mainly relies on manual operation of medical staff and emergency equipment in hospitals. However, in practical applications, this method has many shortcomings. For example, when a patient suddenly develops coronary heart disease, if medical staff cannot arrive at the scene in time, or the hospital's emergency equipment is insufficient, the best time for patient treatment may be delayed. In addition, manual emergency operation requires high professional skills and physical strength of medical staff. During chest compressions on patients, each compression should cause the chest to be pressed down 5-6cm. Too shallow compression cannot guarantee cardiac output, and too deep compression will cause damage to the sternum and ribs. Manual chest compression cannot ensure that the patient's chest is pressed down within the optimal range each time. Therefore, there is an urgent need for a first aid device that can perform stable and standard compressions. Summary of the invention

[0004] The present invention aims to provide a coronary heart disease first aid device for cardiovascular medicine, which solves the problem of easy fatigue and substandard pressing during manual first aid.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: A coronary heart disease emergency rescue device for cardiovascular medicine, comprising a box body with an opening at the top, a cover plate rotatably connected to the opening of the box body, a rotating shaft and a driving assembly rotatably connected to the box body with one end located outside the box body, the driving assembly can drive the rotating shaft to intermittently rotate forward or reverse, and a first screw rod located outside the box body is also integrally formed on the rotating shaft, a pressing tube is threadedly connected to the first screw, and a plurality of limit grooves are circumferentially opened on the side wall of the pressing tube, a limit rod that can interfere with the limit groove is rotatably connected to the bottom of the box body, a pressing head is fixedly connected to the pressing tube, and four support rods are symmetrically arranged at the bottom of the box body, and a pad is detachably connected between two of the support rods located on the same side.

[0006] Furthermore, the driving assembly includes a driving motor, a turning handle is fixedly connected to the output shaft of the driving motor, a connecting rod is provided on the turning handle, a rack is rotatably connected to the connecting rod, the rack is meshed with a gear arranged on the rotating shaft, and the rack is also in contact with a supporting member for supporting the rack, and the supporting member is rotatably connected to the rotating shaft.

[0007] Through the above arrangement, the driving motor can drive the handle and the connecting rod to rotate. After the connecting rod rotates, it can drive the gear to intermittently rotate forward and reverse through the rack. After the gear rotates, it can drive the rotating shaft to rotate, so that the pressing tube and the pressing head can reciprocate to rise or fall under the action of the limit rod, so as to perform standard cardiopulmonary resuscitation operations on the patient. Driving by the driving motor can greatly save the labor intensity of medical staff. At the same time, since the height of the pressing head rising or falling is the same, it is more conducive to improving the standard of the pressing operation and improving the effect of cardiopulmonary resuscitation.

[0008] Furthermore, the rack is provided with a plurality of limiting holes, the connecting rod is rotatably connected in the limiting holes, and the rotating handle is provided with a sliding groove for the connecting rod to slide.

[0009] Through the above arrangement, after the rack is moved upward, the pressing amplitude of the pressing tube and the pressing head can be adjusted up and down by placing the connecting rod in different limit holes, thereby facilitating timely adjustment according to the cardiopulmonary resuscitation situation.

[0010] Furthermore, the pressing head is composed of an upper pressing plate, a lower pressing plate and an elastic cover connected between the upper pressing plate and the lower pressing plate, and an adjusting bolt is threadedly connected to the upper pressing plate, and the adjusting bolt is rotatably connected to the lower pressing plate.

[0011] Through the above arrangement, the distance between the upper pressing plate and the lower pressing plate on one side can be adjusted by means of the adjusting bolt, so that the contact point between the lower pressing plate and the patient changes during the pressing process, thereby being suitable for patients in different conditions.

[0012] Furthermore, a pressing rod is ball-connected on the lower pressing plate, the other end of the upper pressing plate is ball-connected with the lower pressing plate, and the pressing rod and the adjusting bolt are respectively arranged on both sides of the upper pressing plate.

[0013] Through the above arrangement, the adjustment of the pressing force direction of the lower pressing plate and the patient can be achieved by means of the adjusting bolt and the pressing rod.

[0014] Furthermore, a distance sensor is provided on the upper pressing plate, and the distance sensor is electrically connected to a display screen, and the display screen is provided on the box body.

[0015] Through the above settings, the distance that the compression head descends can be monitored in real time with the help of the distance sensor and the display screen, which is convenient for medical staff to adjust the compression distance in time according to the compression situation, which is conducive to improving the effect of ensuring cardiopulmonary resuscitation.

[0016] Furthermore, a plurality of pressure sensors are embedded on the lower pressing plate, and all of the pressure sensors are electrically connected to the display screen respectively.

[0017] Through the above settings, the pressing effect is determined by utilizing the pressure values ​​monitored by each pressure sensor, which is conducive to timely adjustment according to the conditions of different groups of people.

[0018] Furthermore, a counterweight is placed in the box.

[0019] Through the above arrangement, the overall weight of the box can be increased with the help of the counterweight block, which is conducive to maintaining the stability of the first aid process.

[0020] Compared with the prior art, this solution has the following beneficial effects:

[0021] This solution can realize automatic cardiopulmonary resuscitation operation, reduce the labor intensity of medical staff, and provide patients with more standardized and effective first aid measures. At the same time, by adjusting the compression depth, this solution can perform cardiopulmonary resuscitation operation at the first time and adjust the compression depth during the compression process. Compared with traditional cardiopulmonary resuscitation devices, this method can perform first aid and then standardize the actions, shortening the time for precise adjustment in the early stage.

[0031] Example

[0032] like Figures 1 to 7 As shown, a coronary heart disease emergency device for cardiovascular medicine comprises a box body 1 with an opening at the top, and placement grooves are provided on both the front and rear sides of the box body 1, and counterweight blocks 2 are placed in the placement grooves. The counterweight blocks 2 can increase the weight of the box body 1, thereby maintaining the stability of cardiopulmonary resuscitation. A cover plate 3 is rotatably connected to the opening of the box body 1. A rotating shaft 4 with one end located outside the box body 1 and a driving assembly are rotatably connected in the box body 1, and a rotating hole for the rotating shaft 4 to rotate is provided in the box body 1. The driving assembly can drive the rotating shaft 4 to intermittently rotate forward or reversely. The driving assembly includes a driving motor 5, which is bolted into the housing 1. A rotating handle 6 is fixedly connected to the output shaft of the driving motor 5. A sliding groove 7 is provided on the upper surface of the rotating handle 6. A connecting rod 8 is slidably connected in the sliding groove 7. A limiting block 9 is integrally formed on the connecting rod 8. The size of the limiting block 9 is larger than the inner diameter of the limiting hole 11. A rack 10 is rotatably connected to the connecting rod 8. A plurality of spaced limiting holes 11 are provided on the rack 10. The connecting rod 8 is rotatably connected in the limiting hole 11. A gear 12 arranged on the rotating shaft 4 is meshed on one side of the rack 10. The rack 10 also abuts against a support member for supporting the rack 10. In this embodiment, the support member includes a rotating ring 13 and a support block 14. The rotating ring 13 is rotatably connected to the rotating shaft 4. The shape of the support block 14 is U-shaped. The inner side of the support block 14 supports the rack 10. The thickness of the rack 10 is less than the height of the opening of the support block 14.

[0033] The lower side of the rotating shaft 4 is also integrally formed with a first screw 15 located outside the box body 1, and a pressing tube 16 is threadedly connected to the first screw 15. A plurality of limiting grooves 17 are circumferentially provided on the side wall of the pressing tube 16. A limiting rod 18 that can interfere with the limiting groove 17 is rotatably connected to the bottom of the box body 1, and a pressing head is fixedly connected to the bottom of the pressing tube 16. In this embodiment, the pressing head is composed of an upper pressing plate 19, a lower pressing plate 21, and an elastic cover 20 connected between the upper pressing plate 19 and the lower pressing plate 21. A threaded hole is provided on the right side of the upper pressing plate 19, and an adjusting bolt 22 is threadedly connected in the threaded hole. The bottom of the adjusting bolt 22 is rotatably connected to the lower pressing plate 21. The left side of the lower pressing plate 21 is ball-connected with a pressing rod 23 located in the elastic cover 20, and the lower end of the pressing rod 23 is ball-connected with the lower pressing plate 21. The pressing rod 23 and the adjusting bolt 22 are respectively arranged on both sides of the upper pressing plate 19, so that the pressing force angle can be adjusted by means of the pressing rod 23 and the adjusting bolt 22. A distance sensor 24 is embedded in the upper pressing plate 19, and the distance sensor 24 is horizontally arranged on the top of the upper pressing plate 19. The distance sensor 24 is electrically connected to a display screen 25, and the display screen 25 is bolted to the front side wall of the box body 1. A plurality of pressure sensors 26 are embedded in the lower pressing plate 21, and all the pressure sensors 26 are electrically connected to the display screen 25.

[0034] Two grooves are symmetrically provided on the front and rear sides of the bottom of the box body 1, and two support rods 27 are rotatably connected in each groove. A second screw rod 28 is rotatably connected to the lower side of each support rod 27, and a pad 29 is threadedly connected between the two second screw rods 28 located on the same side. When the device is not in use, the pad 29 can be removed and placed in the box body 1 to reduce the volume of the device, which is conducive to carrying and transporting the device.

[0035] The working process of this embodiment:

[0036] When the patient needs cardiopulmonary resuscitation, first take out the two pads 29 from the box 1 and lay them under the patient's back, then turn the support rod 27 out of the groove, and use the second screw 28 on the two support rods 27 on the same side to connect with the pad 29. At this time, start the drive motor 5. After the drive motor 5 is started, it drives one end of the rack 10 to move through the handle 6 and the connecting rod 8. After the rack 10 moves, it can drive the gear 12 to rotate. During the movement of the rack 10, it will drive the support block 14 and the rotating ring 13 to rotate relative to the rotating shaft 4, and the support block 14 will support the rack 10. Because the rack 10 will move back and forth under the drive of the connecting rod 8, all racks 10 can drive the gear 12 to rotate forward and reverse intermittently.

[0037] When performing cardiopulmonary resuscitation, first turn on the drive motor 5 to drive at a slower speed. At this time, by observing the changes in the pressure value on the display and the value change of the distance sensor 24, it is possible to accurately see the pressure of the lower pressing plate 21 on the patient's chest and the depth of the pressing (i.e., the value of the distance sensor 24 changes when the pressure value reaches the maximum from zero), so that the right end of the rack 10 is tilted up according to the actual value, so that the connecting rod 8 quickly moves into the corresponding limit hole 11, thereby adjusting the pressing depth. This method is simple and easy to operate. At the same time, according to the values ​​displayed by different pressure sensors 26, the spacing between the upper pressing plate 19 and the lower pressing plate 21 can be changed by adjusting the bolt 22, so that the force angle of the lower pressing plate 21 on the pressing point occurs during pressing, which is more suitable for different patients. When the connecting rod 8 and the adjusting bolt 22 are adjusted, the drive motor 5 is restored to normal speed.

[0038] During the process of the compression head performing cardiopulmonary resuscitation on the patient, the patient's body is pressed on the two pads 29, which keeps the height of the box 1 stable. At the same time, the weight of the box 1 can be increased by using the counterweight 2, so that the compression head will not move relative to the patient during cardiopulmonary resuscitation, thereby maintaining the reliability of first aid.

[0039] The above are only embodiments of the present invention, and the common knowledge such as the known specific structures and / or characteristics in the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
