Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, in particular to a prone ventilation treatment bed. Background Art
[0002] Prone position therapy refers to placing the patient in a face-down prone position, using the effects of gravity and body position for treatment. By changing the patient's position, the collapsed alveoli can be re-expanded, the residual lung capacity can be increased, the drainage of secretions can be facilitated, oxygenation can be improved, and multiple organ dysfunction and mortality caused by oxygenation disorders can be reduced. Taking prone cardiopulmonary resuscitation as an example, the patient is first placed in a prone position (face down), and then cardiopulmonary resuscitation is performed. Compared with traditional supine cardiopulmonary resuscitation, prone cardiopulmonary resuscitation has the following advantages: 1. It effectively prevents the tongue from sliding backwards and keeps the airway open; 2. It helps the heart re-perfuse blood through gravity, which is conducive to maintaining cerebral perfusion pressure; 3. Vomit and body fluids can flow out naturally with gravity, reducing the risk of drowning and suffocation, etc.
[0003] Currently, due to limitations of medical equipment, the beds used in hospitals only have the function of flipping the head and legs up and down. When the patient needs to flip to a prone position, a nurse is required to assist in the operation, such as assisting the patient to flip to a prone position, placing a pillow under the patient's forehead, placing a pillow under the patient's chest or abdomen, adjusting the trachea to avoid compressing the face, etc. If the patient is awake, he or she can adjust himself or herself and communicate with the nurse. However, if the patient is in a coma, such as a patient who has drowned or suffered from aspiration pneumonia, the patient himself or herself may be in a coma, and flipping into a prone position requires the cooperation of multiple nurses. The workload is very large, which results in a long time required for prone flipping, which is not conducive to rescuing the patient as soon as possible. Summary of the invention

[0014] Furthermore, a fourth spring is provided between the first vertical rod and the second vertical rod.
[0015] Furthermore, the slide plate is provided with a draw cord extending to the patient placement area.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. When the patient needs to be turned over to the prone position, the patient is first placed in the patient placement area outside the dotted line of the upper bed board, and then several fixing belts are successively retracted to make them contact with the patient's head, chest, thigh and calf respectively, and the locking part provided at the end of the fixing belt passes through the buckle, and the locking part is limited by the limiting blocks symmetrically provided on the buckle, so as to fix the patient's head, chest, thigh and calf, and fix the patient on the upper bed board, so as to prevent the patient from falling off the upper bed board during the turning process, thereby ensuring the safety of the patient during the turning process;
[0018] 2. The medical staff is at the head of the bed and slides the upper bed board to the left on the lower bed board. The lower bed board is prevented from falling off from the upper bed board through the limit of several bumps and slots, further ensuring the safety of the patient during the turning process;
[0019] When the support block provided on the support plate moves to the end of the slot, the support block is restricted from continuing to move on the limit block through the cooperation between the protrusion, the slot, the first spring, the support rod and the first groove. With the weight of the upper bed board, the support plate, the support rod and the support block constitute a transfer point connecting the upper bed board and the lower bed board. Then the upper bed board is flipped upward to form a 150-degree angle with the lower bed board and gradually approach the lower bed board, while driving the patient to flip together. Then the limiting effect of the limit block on the lock part is released, so that the lock part falls off from the buckle, thereby loosening the fixing belt, allowing the patient to fall on the lower bed board, and flipping the unconscious patient to a prone position. During the flipping process, one side of the upper bed board is supported by the lower bed board, and the medical staff only needs to support the other side of the upper bed board, thereby greatly reducing the workload of the medical staff in flipping the unconscious patient and improving the efficiency of flipping the patient to a prone position, so as to facilitate the subsequent rescue of the patient as soon as possible.
[0020] 3. After placing the patient in the prone position, move the patient slightly so that the patient's mouth, nose, neck and chest are aligned with the mouth and nose protection cavity, neck protection cavity and chest protection cavity provided on the lower bed board, so that the endotracheal intubation tube, tracheostomy tube and diversion tube pass through the lower bed board respectively and connect with the patient's mouth, nose, neck and chest, so as to facilitate the rescue of the patient in the prone position;
[0021] 4. When the patient needs to be turned over to the prone position, a force greater than the rebound force of the first spring is applied to the upper bed board, and the first inclined surface contacts the second groove. The generated force drives the two support rods to move inward and compresses the first spring, so that the limit block slides out of the second groove smoothly, and the upper bed board moves relative to the lower bed board, which is convenient for the subsequent turning of the patient to the prone position without complicated release steps, thereby improving the efficiency of rescuing the patient;
[0022] When the support block moves to the end of the slot, the first spring drives the support rod to move toward both sides, so that the support rod enters the first groove and contacts the stopper provided on the first groove. The resistance generated by the contact between the two will further limit the up and down movement of the support block on the lower bed board during the flipping process, thereby improving the overall stability of the treatment bed during the flipping process and preventing the patient from being injured.
[0023] After the patient is turned over, the upper bed board can be moved upward. When the external force applied to the upper bed board is too large, the first inclined surface contacts the stopper, and the force generated drives the two support rods to move inward, compressing the first spring, so that the support block slides out of the slot smoothly, and the upper bed board is removed from the lower bed board, thereby reducing the workload of medical staff and facilitating subsequent treatment of the patient.
[0024] 5. When the patient needs to be fixed on the upper bed board, the patient is first placed in the patient placement area outside the dotted line of the upper bed board. Through the cooperation among the fixing belt, the locking part, the buckle, the limiting block, the first protrusion, the second inclined surface and the limiting groove, the limiting block is driven to slide on the buckle, so that the locking part passes through the buckle smoothly, and the fixing belt is further tightened to fix the patient's head, chest, thigh and calf, and fix patients of different body shapes on the upper bed board to prevent patients of different body shapes from falling off the upper bed board during the turning process, thereby ensuring the safety of patients of different body shapes during the turning process;
[0025] After the patient is fixed on the upper bed board, the first protrusion, the first plane, and the limiting groove cooperate to limit the sliding of the lock part relative to the buckle, so that the lock part can only move in one direction on the buckle and cannot slide in the opposite direction to loosen the fixing belt, so as to avoid the external force driving the lock part to move in the opposite direction on the buckle during the flipping process, causing the fixing belt to loosen, so as to avoid the patient falling off the upper bed board during the flipping process, thereby ensuring the safety of the patient during the flipping process;
[0026] 6. When the patient needs to be released from the upper bed board, the slide plate, the second protrusion, the limit block, the wedge, and the third inclined plane cooperate to drive several limit blocks to slide toward both sides at the same time, thereby releasing the fixation of the limit blocks to the lock part, loosening the fixing belt, releasing the fixation of the patient on the upper bed board, and then placing the patient on the lower bed board, without releasing the restrictions of several limit blocks on the lock part one by one, thereby improving the efficiency of turning the patient to the prone position, and facilitating the subsequent rescue of the patient as soon as possible;
[0027] In addition, when the slide plate is pressed down, the first vertical rod will be driven to move down together, and the fixing block will be driven to move to both sides through the cooperation among the third protrusion, the fifth inclined surface, the fixing block and the fourth inclined surface, so that the slide plate can move down smoothly. Then, after the fixing of the locking part by the limit block is released, the upward movement of the slide plate is limited through the cooperation among the third protrusion, the second plane and the fixing block, thereby releasing the fixing of the locking part on the buckle for a long time, making it easy for the locking part to be detached from the buckle, and there is no need for medical staff to press the slide plate for a long time, thereby improving the efficiency of turning the patient to the prone position, and facilitating the subsequent rescue of the patient as soon as possible.
[0028] 7. After loosening the fixing belt, the third protrusion and the fourth protrusion cooperate with each other before the fixing block is reset, so as to realize the reset of the slide board, and drive the limit block to reset under the action of the rebound force of the second spring, and re-limit the unidirectional sliding of the lock plate on the buckle, so as to facilitate the subsequent fixation of the patient and improve the efficiency of turning the patient to the prone position.

[0049] The bottom of the support plate 4 and the upper bed board 2 are respectively provided with a support block 9 and a plurality of protrusions 10, the lower bed board 1 is symmetrically provided with a slot 11 that is in sliding contact with the support block 9 and the protrusion 10, and the two sides of the slot 11 are respectively provided with a first groove 12, and the support block 9 is symmetrically provided with a support rod 13, the side surfaces of the support rod 13 are respectively in contact with the first groove 12, and limit the limit block 8 from sliding in the slot 11, and a first spring 1 is provided between two adjacent support rods 13. 4. The medical staff is located at the head of the bed and slides the upper bed board 2 to the left on the lower bed board 1. The lower bed board 1 is prevented from falling off from the upper bed board 2 by the limiting of a plurality of protrusions 10 and the slots 11, thereby further ensuring the safety of the patient during the turning process. When the support block 9 provided on the support plate 4 moves to the end of the slot 11, a plurality of protrusions 10 have slid out from one side of the slot 11, and at the same time, under the action of the rebound force of the first spring 14, the two support rods 13 are driven to slide out to both sides so that they enter the slots. The first grooves 12 on both sides of 11 are in contact with the first grooves 12 through the side of the support rod 13, and the generated resistance will limit the support block 9 from continuing to move on the limit block 8. With the weight of the upper bed board 2, the support board 4, the support rod 13 and the support block 9 constitute the transfer point connecting the upper bed board 2 and the lower bed board 1. Then the upper bed board 2 is flipped upward to form an angle of 150 degrees with the lower bed board 1 and gradually approach the lower bed board 1, while driving the patient to flip together. Then the limiting effect of the limit block 8 on the lock part 5 is released, so that the lock part 5 falls off from the buckle 7, thereby loosening the fixing belt 3, allowing the patient to fall on the lower bed board 1, and flipping the patient in a coma to a prone position. During the flipping process, one side of the upper bed board 2 is supported by the lower bed board 1, and the medical staff only needs to support the other side of the upper bed board 2, thereby greatly reducing the workload of the medical staff in flipping the patient in a coma, and improving the efficiency of flipping the patient to a prone position, so as to facilitate the subsequent rescue of the patient as soon as possible.

[0061] The present invention provides a prone position ventilation treatment bed, such as Figure 1-Figure 5 As shown, when the bed is in the standby state, the lower bed board 1 and the upper bed board 2 are placed together. At this time, the resistance generated by the sliding contact between the protrusion 10, the support block 9 and the slot 11 limits the relative rotation of the upper bed board 2 and the lower bed board 1, ensuring normal use of the bed when the patient lies flat;
[0062] When the patient needs to be turned over to the prone position, the patient is first placed in the patient placement area 6 outside the dotted line of the upper bed board 2, and then several fixing belts 3 are successively retracted to make them contact with the patient's head, chest, thigh and calf respectively, and the locking portion 5 provided at the end of the fixing belt 3 passes through the buckle 7, and the locking portion 5 is limited by the limiting blocks 8 symmetrically provided on the buckle 7, so as to fix the patient's head, chest, thigh and calf, and fix the patient on the upper bed board 2, so as to prevent the patient from falling off the upper bed board 2 during the turning process, thereby ensuring the safety of the patient during the turning process;
[0063] Then the medical staff is located at the head of the bed and slides the upper bed board 2 to the left on the lower bed board 1. The lower bed board 1 is prevented from falling off from the upper bed board 2 by the limiting of several protrusions 10 and the slots 11, further ensuring the safety of the patient during the turning process; when the support block 9 provided on the support plate 4 moves to the end of the slot 11, several protrusions 10 have slid out from one side of the slot 11, and at the same time, under the action of the rebound force of the first spring 14, the two support rods 13 are driven to slide out to both sides, so that they enter the first grooves 12 provided on both sides of the slot 11. The side of the support rod 13 contacts the first groove 12, and the resistance generated will limit the support block 9 from continuing to move on the limit block 8, and cooperate with the own weight of the upper bed board 2, so that the support plate 4 and the support rod 13 and the support block 9 constitute the transfer point connecting the upper bed board 2 and the lower bed board 1, then flip the upper bed board 2 upwards to make it form an angle of 150 degrees with the lower bed board 1, and gradually approach the lower bed board 1, while driving the patient to flip together, then release the limiting effect of the limit block 8 on the lock part 5, so that the lock part 5 falls off from the buckle 7, thereby loosening the fixing belt 3, allowing the patient to fall on the lower bed board 1, and flip the patient in a coma to a prone position. During the flipping process, one side of the upper bed board 2 is supported by the lower bed board 1, and the medical staff only needs to support the other side of the upper bed board 2, thereby greatly reducing the workload of the medical staff in flipping the patient in a coma, and improving the efficiency of flipping the patient to the prone position, so as to facilitate the subsequent rescue of the patient as soon as possible;
[0064] After placing the patient in the prone position, the patient is moved slightly so that the patient's mouth, nose, neck and chest are aligned with the mouth and nose protection cavity 15, neck protection cavity 16 and chest protection cavity 17 provided on the lower bed board 1, so that the endotracheal tube, tracheostomy tube and diversion tube are respectively passed through the lower bed board 1 and connected to the patient's mouth, nose, neck and chest, so as to facilitate the rescue of the patient in the prone position.
[0065] Example 2
[0066] On the basis of Example 1, Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, when the bed is in the standby state, the first inclined surface 20 contacts the second groove 21, and the resistance generated will limit the relative movement of the upper bed board 2 and the lower bed board 1, ensuring normal use of the bed in a lying state;
[0067] When the patient needs to be turned over to the prone position, a force greater than the rebound force of the first spring 14 is applied to the upper bed board 2, and the first inclined surface 20 contacts the second groove 21. The generated force drives the two support rods 13 to move inward and compresses the first spring 14, so that the limit block 8 can slide out of the second groove 21 smoothly, so that the upper bed board 2 moves relative to the lower bed board 1, which is convenient for the subsequent turning of the patient to the prone position without the need for cumbersome release steps, thereby improving the efficiency of rescuing the patient;
[0068] Then, the roller 22 contacts the slot 11 to reduce the friction between the support block 9 and the protrusion 10 and the slot 11, making it easier for the support block 9 and the protrusion 10 to slide on the slot 11, thereby reducing the workload required for medical staff to push the upper bed board 2 and improving the efficiency of rescuing the patient; when the support block 9 moves to the end of the slot 11, the first spring 14 drives the support rod 13 to move toward both sides, so that the support rod 13 enters the first groove 12 and contacts with the stopper 19 provided on the first groove 12. The resistance generated by the contact between the two will further limit the support block 9 from moving up and down on the lower bed board 1 during the flipping process, thereby improving the overall stability of the flipping process of the treatment bed and preventing the patient from being injured; at the same time, a hinge 23 is provided between the support plate 4 and the upper bed board 2, so that the upper bed board 2 can rotate more smoothly relative to the support plate 4, thereby preventing the patient from falling off the upper bed board 2 during the flipping process, thereby ensuring the safety of the patient during the flipping process;
[0069] After the patient is flipped over, the upper bed board 2 can be moved upward. When the external force applied to the upper bed board 2 is too large, the first inclined surface 20 contacts the block 19, and the force generated will drive the two support rods 13 to move inward, compressing the first spring 14, so that the support block 9 can slide out of the groove 18 smoothly, and the upper bed board 2 can be removed from the lower bed board 1, thereby reducing the workload of medical staff and facilitating subsequent treatment of the patient.
[0070] Example 3
[0071] On the basis of Example 1, Figure 8 and Fig. 9As shown, when the patient needs to be fixed on the upper bed board 2, the patient is first placed in the patient placement area 6 outside the dotted line of the upper bed board 2, and then a plurality of fixing belts 3 are successively retracted to make them contact with the patient's head, chest, thigh and calf respectively, and the locking portion 5 provided at the end of the fixing belt 3 passes through the buckle 7, so that the first protrusion 24 provided on the limiting block 8 contacts with the locking portion 5, and when the locking portion 5 is moved forward to tighten the fixing belt 3, the second inclined surface 26 provided on one side of the first protrusion 24 contacts with one side of the limiting groove 25 provided on the locking portion 5, and the generated component force drives the limiting block 8 to slide on the buckle 7, so that the locking portion 5 passes through the buckle 7 smoothly, and the fixing belt 3 is further tightened, so as to fix the patient's head, chest, thigh and calf, and fix patients of different body shapes on the upper bed board 2, so as to prevent patients of different body shapes from falling off from the upper bed board 2 during the turning process, thereby ensuring the safety of patients of different body shapes during the turning process;
[0072] When the patient is fixed on the upper bed board 2, the first plane 27 provided on the other side of the first protrusion 24 contacts the other side of the limiting groove 25, and the generated resistance will limit the sliding of the lock part 5 relative to the buckle 7, so that the lock part 5 can only move in one direction on the buckle 7, and cannot slide in the opposite direction to loosen the fixing belt 3, so as to avoid that the external force drives the lock part 5 to move in the opposite direction on the buckle 7 during the flipping process, causing the fixing belt 3 to loosen, thereby preventing the patient from falling off the upper bed board 2 during the flipping process, thereby ensuring the safety of the patient during the flipping process.
[0073] Example 4
[0074] On the basis of Example 3, Figure 8 and Fig.10 As shown, when the patient needs to be released from the upper bed board 2, the slide plate 29 is pressed down to make the slide plate 29 slide on the upper bed board 2, so that the several second protrusions 30 provided at the bottom of the slide plate 29 respectively contact the wedge blocks 31 provided on the top of the limit block 8, and further contact the wedge blocks 31 through the third inclined surface 32 provided on one side of the second protrusion 30. The generated force will drive the several limit blocks 8 to slide toward both sides at the same time, thereby releasing the fixation of the limit blocks 8 to the lock part 5, realizing the loosening of the fixing belt 3, releasing the fixation of the patient on the upper bed board 2, and then placing the patient on the lower bed board 1, without releasing the restrictions of the several limit blocks 8 on the lock part 5 one by one, thereby improving the efficiency of turning the patient to the prone position, and facilitating the subsequent rescue of the patient as soon as possible;
[0075] In addition, when the slide plate 29 is pressed down, the first vertical rod 33 is driven to move downward together, and the fifth inclined surface 38 provided on the third protrusion 34 contacts the fourth inclined surface 36 provided on the upper side of the fixing block 35, driving the fixing block 35 to move toward both sides, so that the slide plate 29 moves downward smoothly, and then after the fixing of the locking portion 5 by the limiting block 8 is released, the second plane 37 provided on the upper side of the third protrusion 34 contacts the fixing block 35, and the slide plate 29 is restricted from moving upward, thereby releasing the fixing of the locking portion 5 on the buckle 7 for a long time, making it easy for the locking portion 5 to detach from the buckle 7, and there is no need for medical staff to press the slide plate 29 for a long time, thereby improving the efficiency of turning the patient to the prone position, and facilitating the subsequent rescue of the patient as soon as possible;
[0076] After the fixing belt 3 is loosened, the second vertical rod 40 is pressed to make the second vertical rod 40 slide downward on the first vertical rod 33, so that the fourth protrusion 41 contacts the fourth inclined surface 36 provided on the upper side of the fixing block 35, and the fixing block 35 is driven to move toward both sides, so that the fourth protrusion 41 passes through the fixing block 35 smoothly, until the fourth protrusion 41 contacts the second flat surface 37 provided on the upper side of the third protrusion 34, and the fixing block 35 is reset under the action of the rebound force of the third spring 39, and then the slide plate 29 is pushed upward, driving the first vertical rod 33 and the second The vertical rod 40 moves upward together, contacts the fixing block 35 through the sixth inclined surface 42 provided on the upper side of the fourth protrusion 41, and the generated force drives the fixing block 35 to move to both sides again, and before the fixing block 35 is reset, the third protrusion 34 and the fourth protrusion 41 pass through the fixing block 35 together to realize the reset of the slide plate 29, and under the action of the rebound force of the second spring 28, drive the limit block 8 to reset, and re-limit the unidirectional sliding of the lock plate on the buckle 7, so as to facilitate the subsequent fixation of the patient and improve the efficiency of turning the patient to the prone position.
