[0002] Heart failure is also called left heart failure. Acute left heart failure refers to acute left heart failure, which is mainly caused by the damage, decline and failure of left ventricular function. After the left ventricular function is damaged and fails, it will cause congestion in the pulmonary circulation, which is called pulmonary congestion. The symptoms often manifest are symptoms of pulmonary edema, including shortness of breath, inability to lie flat, need for semi-recumbent or sitting position, cyanosis of lips, inability to lie flat at night, patients cough, wheeze, sputum, mainly thin sputum, severe patients may have pink foamy sputum, which contains a certain amount of blood, which is the main symptom of the lungs.

[0003] The bed surface of the cardiopulmonary resuscitation rescue bed used in existing hospitals is flat. When needed, the backboard can be adjusted to raise the patient's back. However, in the rescue of patients with acute left heart failure, sitting can quickly reduce the amount of blood returning to the heart, which is a necessary position for rescuing such patients. The rescue beds currently used cannot put the patient in a sitting position well, which is not conducive to the smooth flow of the patient's airway during rescue. They are inconvenient to use and have poor practicality. Utility Model Content

[0028] The control device includes a control threaded rod 7, which is rotatably connected to the mounting frame 2. The mounting frame 2 is connected to a second motor 13, and the output shaft of the second motor 13 is connected to the control threaded rod 7. The control threaded rod 7 is threadedly connected to a moving block 12, and the moving block 12 is in contact with the bottom of the mounting frame 2. The moving block 12 is rotationally limited by the mounting frame 2. The moving block 12 is hinged with a support rod 8, and the free end of the support rod 8 is hinged with a back plate 10. The moving block 12 is connected to two groups of support rods 8, and the two groups of support rods 8 are symmetrically arranged front and back about the center line of the moving block 12.

[0029] The bottom of the leg board 15 is connected with a protection frame 20, which contacts the main bed board 1. The leg board 15 is provided with a limit groove 17, and the foot board 18 is slidably connected with the limit groove 17. The foot board 18 can only slide left and right along the limit groove 17. The protection frame 20 is rotatably connected with an adjustment threaded rod 19. The protection frame 20 is connected with a third motor 16, and the output shaft of the third motor 16 is connected with the adjustment threaded rod 19. The foot board 18 is threadedly connected with the adjustment threaded rod 19. The main bed board 1 is connected with a collection box 21, and the collection box 21 is connected with a collection drawer 22. The protection frame 20 contacts the collection box 21, so that the leg board 15 can be placed stably.

[0031] The second motor 13 drives the control threaded rod 7 to rotate, and the mounting frame 2 acts as a rotation limiter for the moving block 12. Therefore, as the rotating rod 4 of the control threaded rod 7 moves, the moving block 12 moves left or right along the threaded rod, thereby driving the support rod 8 to move. Since the hip plate 14 is fixedly connected to the mounting frame 2, the back plate 10 can rotate relative to the hip plate 14 at this time to complete the adjustment of the angle of the back plate 10.

[0032] The adjusting threaded rod 19 is driven to rotate by the third motor 16, and the limiting groove 17 has a rotation limiting effect on the foot plate 18. Therefore, as the adjusting threaded rod 19 rotates, the foot plate 18 moves leftward or rightward along the adjusting threaded rod 19, thereby completing the adjustment of the position of the foot plate 18.

[0033] The specific implementation process is as follows:

[0034] When using Figure 1 As shown, at this time, the protection frame 20 is in conflict with the collection box 21, and the backboard 10 is not rotated. At this time, the patient can lie flat on the bed, and the second motor 13 can be controlled to drive the backboard 10 to rotate so that the patient can lie on the bed with his back propped up. When the patient needs to be in a sitting position, the backboard 10 is first rotated so that the backboard 10 and the hip board 14 have a certain angle to facilitate the patient to lean back, and then the first motor 6 is started. The first motor 6 drives the worm 24 to rotate and then drives the worm wheel 5 and the rotating rod 4 to rotate. The rotating rod 4 rotates to drive the installation The frame 2 rotates, causing the mounting frame 2 to rotate ninety degrees, thereby causing the leg board 15 to rotate away from the upper side of the collection box 21. The leg board 15 can be rotated downward relative to the hip board 14 after no longer being resisted by the collection box 21, until the push board resists the edge of the main bed board 1. At this time, the push boards form a ninety-degree angle with each other, and the leg board 15, the hip board 14 and the back board 10 form a chair structure, allowing the patient to maintain a sitting posture. During this period, the third motor 16 can be controlled to adjust the position of the foot board 18 to facilitate the patient to put his feet; when restoring the original state, the reverse operation can be performed.

[0035] The technical solution is to respectively set a hip board 14, a back board 10 and a leg board 15 on the main bed board 1 to support different parts of the human body respectively. The angle between the back board 10 and the hip board 14 can be adjusted by the control device later to improve the patient's lying posture. At the same time, the first motor 6 can be driven to rotate, thereby quickly adjusting the positions of the hip board 14, the back board 10 and the leg board 15, so that the leg board 15 can be quickly lowered relative to the hip board 14, so that the patient can quickly change to a sitting position, keep the patient's airway unobstructed, and improve the rescue effect; the transmission method of the worm gear 5 and the worm 24 is simple in structure, easy to operate, and has a reverse self-locking function, so that the connection between the installation frame 2 and the main bed body can be more stable and easy to use; the back board 10 can be driven to rotate by controlling the second motor 13 to drive the control threaded rod 7 to rotate, which has a simple structure, convenient adjustment, and is also easy to maintain later; The foot plate 18 provides a fulcrum for the patient's feet, avoiding congestion caused by the patient's feet being suspended in the air when the patient is in a sitting position, thereby improving the use effect; the position of the foot plate 18 can be adjusted by the third motor 16 to drive the adjusting threaded rod 19 to rotate, so that it is suitable for patients of different heights and body shapes, thereby improving the practicality and applicability of the device; rescue tools can be stored in the collection box 21 and the collection drawer 22 for timely use, thereby improving the rescue effect of the device; the support effect of the back plate 10 is improved by multiple groups of support rods 8, and the use stability of the back plate 10 is improved; a fixed frame 3 is provided to facilitate the protection of the first motor 6; the inspection door 25 facilitates the maintenance of the first motor 6; the protective plate 11 can protect the patient; the protective plate 11 is installed by sliding connection with the card frame 23, and the protective plate 11 can be taken out for desktop use later, thereby further improving the practicality of the device.
