Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an automatic sensing rotation support device for the head of a patient undergoing ventilation in a prone position. Background Art

[0002] Prone ventilation is an effective treatment method that places the patient in a prone position and uses the effect of gravity to improve the patient's ventilation function, increase the functional residual capacity of the lungs, and improve oxygenation. Prone ventilation has a significant therapeutic effect on patients with ARDS, severe lung respiratory diseases, etc., and can reduce mortality and improve treatment effects. However, when implementing prone ventilation, the patient's head needs to be outside the treatment bed and lacks support, resulting in the patient's head hanging in the air, causing severe discomfort, and increasing the workload of medical staff. In addition, the fixation of the patient's head position also requires manual adjustment by medical staff, which is cumbersome and difficult to achieve precise control, affecting the treatment effect.

[0003] Existing prone ventilation equipment generally has some defects. First, the adjustment of the patient's head position relies on manual operation by medical staff, which is cumbersome and prone to errors. Secondly, the patient's head lacks support, and the suspended state reduces the patient's comfort and increases the patient's pain. Thirdly, the existing equipment cannot automatically control the opening and closing of the front neck support plate and the back neck support plate, which is inconvenient to operate and increases the workload of medical staff. In addition, when adjusting the patient's head position, it is difficult to achieve precise control because the head is not supported by manual rotation by medical staff. Therefore, there is a need for a prone ventilation device that can accurately adjust the patient's head position to improve the patient's comfort, reduce the workload of medical staff, and improve the treatment effect.

[0033] See also Figure 3 In the embodiment of the present invention, the neck support frame 2 includes a back neck support plate 21 and a front neck support plate 22. One end of the back neck support plate 21 is hinged to one end of the front neck support plate 22. A rotation sensing mechanism 23 is further provided on the back neck support plate 21. A groove 24 is provided on the inner top side of the back neck support plate 21.

[0034] See also Figure 3-Figure 4 In the embodiment of the present invention, the rotation sensing mechanism 23 includes a T-shaped shaft 231 that slides longitudinally through the upper part of the back neck support plate 21, and an arc-shaped plate 232 corresponding to the groove 24 is provided at the lower end of the T-shaped shaft 231. A rack 233 is provided on one side of the T-shaped shaft 231. The rotation sensing mechanism 23 also includes a limit seat 234 provided on the upper part of the back neck support plate 21, and a gear 235 is rotatably provided on one side of the limit seat 234. The gear 235 is meshed with the rack 233, and An eccentric rod 236 is hinged on one side of the gear 235 near the edge, and an arc rod 237 that matches the curvature of the back neck support plate 21 is hinged on the end of the eccentric rod 236 away from its hinge point. The arc rod 237 is slidably set on the outer side of the back neck support plate 21, and the end of the arc rod 237 away from the eccentric rod 236 is hinged on a connecting rod 238, one end of the connecting rod 238 is connected to a limiting strip 239, and one end of the limiting strip 239 is connected to the side of one end of the front neck support plate 22.

[0035] See also Figure 5-Figure 6 In this embodiment of the present invention, the clamping portion includes a slot 211 provided at one end of the rear neck support plate 21, and a clamping slot 212 is provided on both sides of the interior of the slot 211. An electromagnet 213 is provided on the inner side of the clamping slot 212. The clamping portion also includes an insert block 221 provided at one end of the front neck support plate 22. The insert block 221 is adapted to the slot 211, and a limiting slot 222 is provided on both sides of the insert block 221. An iron block 223 is slidably provided on the inner side of the limiting slot 222, and the iron block 223 is connected to the inner side of the limiting slot 222 by a spring 224.

[0036] See also Figure 2 In the embodiment of the present invention, the lifting assembly 3 includes a stepper motor 31 installed on the front side of the bed 12, the output shaft of the stepper motor 31 is connected to a threaded rod 33, the outside of the threaded rod 33 is screwed with an L-shaped rod 32 by a thread, one end of the L-shaped rod 32 is fixedly set on one side of the back neck support plate 21, and the lifting assembly 3 also includes a limit sleeve 34 provided on the front side of the bed 12, and the other end of the L-shaped rod 32 slides longitudinally and is inserted into the limit sleeve 34.

[0037] In the above scheme: the stepping motor 31 drives the threaded rod 33 to rotate, and the threaded rod 33 drives the L-shaped rod 32 to move downward, and the L-shaped rod 32 will drive the neck support frame 2 to move downward, so that the back neck support plate 21 moves toward the back of the patient's neck and is stuck to the back of the patient's neck to support the back of the patient's neck. When the back neck support plate 21 moves downward, the curved plate 232 will contact the back of the neck. After contact, the back neck support plate 21 continues to move downward, and the back neck will generate a reaction force on the curved plate 232, so that the curved plate 232 drives the T-shaped shaft 231 to move upward, and the rack 233 on one side of the T-shaped shaft 231 will drive the gear 235 meshing with it to rotate clockwise, and the gear 235 will drive the eccentric rod 236 to do eccentric movement, and the eccentric rod 236 will drive the curved rod 237 to slide clockwise on the back neck support plate 21. The connecting rod 238 at one end of the arc-shaped rod 237 will cause the limit bar 239 to drive the front neck support plate 22 to rotate toward the front neck direction. When the arc plate 232 moves into the groove 24, the plug 221 at one end of the front neck support plate 22 is just completely inserted into the slot 211 on the back neck support plate 21. At this time, the iron block 223 just corresponds to the card slot 212 in the slot 211, and the electromagnet 213 that is powered on has magnetism and adsorbs the iron block 223. Under the elasticity of the spring 224, the iron block 223 will move toward the position of the electromagnet 213 until it is stuck in the card slot 212 and adsorbed on the electromagnet 213, so that the front neck support plate 22 can be fixed, which plays a supporting role on the front neck, ensuring that the patient's neck posture is constant, which is beneficial to the effect of the patient's supine ventilation treatment.

[0038] When the front neck support plate 22 needs to be opened, the power supply of the electromagnet 213 is turned off first, and the electromagnet 213 releases the adsorption of the iron block 223, and the spring 224 resets the iron block 223 and moves it into the limit groove 222. Then, the stepper motor 31 is operated again, and the threaded rod 33 drives the L-shaped rod 32 to move upward, thereby driving the neck support frame 2 to move upward, so that the arc plate 232 no longer presses against the back of the patient's neck. At this time, under the gravity of the arc plate 232, the T-shaped shaft 231 will move downward, and the rack 233 on one side of the T-shaped shaft 231 will drive the gear 235 to rotate counterclockwise, thereby causing the eccentric rod 236 to drive the arc rod 237 to rotate counterclockwise around the back neck support plate 21, so that the second connecting rod 238 will cause the limit bar 239 to drive the front neck support plate 22 to open, so that the plug block 221 at one end of the front neck support plate 22 will be disengaged from the slot 211. When the arc plate 232 completely leaves the back neck, the front neck support plate 22 will be completely opened.

[0039] For further information, see Figure 3-Figure 4In the embodiment of the present invention, a T-shaped block 2310 is provided on the inner side of the arc rod 237, and a T-shaped slot 25 that is compatible with the T-shaped block 2310 is provided on the outer side of the back neck support plate 21. One end of the T-shaped block 2310 is slidably provided in the T-shaped slot 25. When the arc rod 237 slides on the back neck support plate 21, the T-shaped block 2310 will slide in the T-shaped slot 25, thereby guiding the arc rod 237.

[0040] For further information, see Figure 3-Figure 4 In the embodiment of the present invention, the back neck support plate 21 and the front neck support plate 22 are both semicircular, and when combined, they form a circle that fits the neck. The back neck support plate 21 and the front neck support plate 22 are both made of rubber material, and their elasticity adapts to necks of different sizes. The back neck support plate 21 and the front neck support plate 22 are connected by a clamping part after being combined.

[0041] For further information, see Figure 3-Figure 4 In this embodiment of the present invention, after the back neck support plate 21 and the front neck support plate 22 are merged, the insert block 221 is completely inserted into the slot 211, and at this time the iron block 223 corresponds to the card slot 212. After the arc plate 232 moves into the groove 24, the back neck support plate 21 and the front neck support plate 22 are just merged.

[0042] The second embodiment differs from the first embodiment in that:

[0043] See also Figure 3 and Figure 7 In an embodiment of the present invention, the automatic sensing rotation support device for the head of a patient undergoing prone ventilation also includes a positioning mechanism 6, which includes an airbag cushion 62 arranged on both sides of the back neck support plate 21 and a tube body 61 on the front side thereof, and the inner sides of both ends of the tube body 61 are connected to the airbag cushion 62 through a branch pipe 63.

[0044] See also Figure 2 In the embodiment of the present invention, an air pump 4 is installed at the bottom of the adjustable base 1, the output end of the air pump 4 is connected to a delivery pipe 5, and the other end of the delivery pipe 5 is connected to the outer side of the tube body 61.

[0045] In the above scheme: when the head position needs to be adjusted, according to the above method, as long as the front neck support plate 22 is opened a little bit and no longer supports the front neck, the upward movement of the back neck support plate 21 is stopped, and the air pump 4 is started at this time. The air pump 4 inflates the two airbag cushions 62 through the delivery tube 5, the tube body 61 and the branch tube 63. The airbag cushions 62 inflate to clamp the two sides of the patient's neck, keeping the patient's neck motionless. Then the medical staff holds the patient's head and gently rotates it.

[0046] The third embodiment differs from the first embodiment in that:

[0047] See also Figure 2 and Figure 8 In the embodiment of the present invention, the adjustable base 1 includes an adjusting seat 11, one side of the adjusting seat 11 is hinged to a horizontal plate 12, and a cavity 13 is provided inside the adjusting seat 11, a screw 14 is rotatably provided in the cavity 13, and a servo motor 15 for driving the screw 14 to rotate is installed on the other side of the adjusting seat 11, and a moving seat 16 is screwed to the outside of the screw 14 through a thread, and a connecting rod 17 is hinged to the upper part of the moving seat 16, and the other end of the connecting rod 17 is hinged to the bottom of the horizontal plate 12, and a strip groove is provided on the upper part of the adjusting seat 11, and the connecting rod 17 passes through the strip groove.

[0048] In the above scheme: the patient lies on the bed 12, and the servo motor 15 drives the screw 14 to rotate, the screw 14 drives the movable seat 16 to move, the movable seat 16 drives the connecting rod 17 to move, and the connecting rod 17 drives the bed 12 to rotate, adjust the angle of the bed 12, and adjust the patient's lying position to a suitable angle according to needs.

[0049] Working principle: The patient lies on the bed 12, and the servo motor 15 drives the screw 14 to rotate, the screw 14 drives the moving seat 16 to move, the moving seat 16 drives the connecting rod 17 to move, and the connecting rod 17 drives the bed 12 to rotate, and adjust the angle of the bed 12. According to the needs, the patient's lying position is adjusted to a suitable angle;

[0050] Then, the power supply of the electromagnet 213 in the card slot 212 is turned on first, and then the stepping motor 31 drives the threaded rod 33 to rotate, and the threaded rod 33 drives the L-shaped rod 32 to move downward, and the L-shaped rod 32 will drive the neck support frame 2 to move downward, so that the back neck support plate 21 moves toward the back of the patient's neck and is stuck to the back of the patient's neck to support the back of the patient's neck. When the back neck support plate 21 moves downward, the curved plate 232 will contact the back of the neck. After contact, the back neck support plate 21 continues to move downward, and the back of the neck will generate a reaction force on the curved plate 232, so that the curved plate 232 drives the T-shaped shaft 231 to move upward, and the rack 233 on one side of the T-shaped shaft 231 will drive the gear 235 meshing with it to rotate clockwise, and the gear 235 will drive the eccentric rod 236 to do eccentric movement, and the eccentric rod 236 will drive the curved rod 237 to move on the back neck support plate When the front neck support plate 22 is rotated in the direction of the front neck, the arc plate 232 moves into the groove 24, and the plug 221 at one end of the front neck support plate 22 is completely inserted into the slot 211 on the back neck support plate 21. At this time, the iron block 223 corresponds to the slot 212 in the slot 211, and the electromagnet 213 connected to the power supply has magnetism and attracts the iron block 223. Under the elasticity of the spring 224, the iron block 223 moves toward the position of the electromagnet 213 until it is stuck in the slot 212 and is attracted to the electromagnet 213, thereby fixing the front neck support plate 22, supporting the front neck, ensuring the constant posture of the patient's neck, and facilitating the effect of the patient's supine ventilation treatment.

[0051] When the front neck support plate 22 needs to be opened, the power supply of the electromagnet 213 is turned off first, and the electromagnet 213 releases the adsorption of the iron block 223, and the spring 224 resets the iron block 223 and moves it into the limit groove 222. Then, the stepper motor 31 is operated again, and the threaded rod 33 drives the L-shaped rod 32 to move upward, thereby driving the neck support frame 2 to move upward, so that the arc plate 232 no longer presses against the back of the patient's neck. At this time, under the gravity of the arc plate 232, the T-shaped shaft 231 will move downward, and the rack 233 on one side of the T-shaped shaft 231 will drive the gear 235 to rotate counterclockwise, thereby causing the eccentric rod 236 to drive the curved rod 237 to rotate counterclockwise around the back neck support plate 21. In this way, the second connecting rod 238 will cause the limit bar 239 to drive the front neck support plate 22 to open, so that the insert 221 at one end of the front neck support plate 22 is disengaged from the slot 211. When the curved plate 232 completely leaves the back neck, the front neck support plate 22 will be completely opened;

[0052] When the head position needs to be adjusted, according to the above method, as long as the front neck support plate 22 is opened a little bit and no longer supports the front neck, the upward movement of the back neck support plate 21 is stopped, and the air pump 4 is started at this time. The air pump 4 inflates the two airbag cushions 62 through the delivery tube 5, the tube body 61 and the branch tube 63. The airbag cushions 62 inflate to clamp the two sides of the patient's neck, keeping the patient's neck motionless. Then the medical staff holds the patient's head and gently rotates it.
