The head and neck pillow plate 3 moves upward to synchronously support and protect the patient's head and neck, while making the patient's turning process more comfortable, avoiding the situation in which the head and neck have no support point during the turning process, resulting in slower blood flow in the neck, numbness and discomfort; At the same time, reference Figure 2 The first rotating shaft 27 on the right side rotates to drive the second gear 41 on the right side to rotate, and the second gear 41 on the right side rotates to drive the moving rod 42 on the left side to move rightward, and the moving rod 42 on the left side moves rightward to drive the third rotating rod 43 on the left side to move rightward, and the third rotating rod 43 on the left side moves rightward to drive the protective plate 4 on the left side to move upward, and the protective plate 4 on the left side moves upward to protect the patient when turning over, making the turning process more convenient, avoiding the situation where the patient turns over too much and falls under the bed, and improving the safety of the device; At the same time, reference Figure 3 and Figure 7 The second rotating shaft 212 on the right side rotates to drive the first bevel gear 51 on the right side to rotate, the first bevel gear 51 on the right side rotates to drive the second bevel gear 52 on the right side to rotate, the second bevel gear 52 on the right side rotates to drive the fifth rotating shaft 53 on the right side to rotate, the fifth rotating shaft 53 on the right side rotates to drive the turntable 54 on the right side to rotate, the turntable 54 on the right side rotates to drive the rotating column 55 on the right side to rotate, the rotating column 55 on the right side rotates to drive the dial rod 56 on the right side to move back and forth left and right, the dial rod 56 on the right side moves back and forth left and right to drive the third movable plate 57 on the right side to move back and forth left and right, the third movable plate 57 on the right side moves back and forth left and right to drive the rolling massage head 5 on the right side to move back and forth left and right, the rolling massage head 5 on the right side moves back and forth to perform reciprocating rolling massage on the patient's back, preventing the patient from feeling uncomfortable due to slow blood circulation in the back caused by lying flat on the bed for a long time.

[0020] The present invention realizes the rotation of the right side body position conversion plate by setting a rotation mechanism, thereby realizing the turning of the patient on one side to realize the body position conversion, preventing the patient from being heavy and often requiring the cooperation of several nurses or family members to complete the work, which is more time-consuming and labor-intensive, and facilitating the examination or dressing change of the patient; similarly, when the driving member rotates in the opposite direction to drive the threaded rod to rotate, at this time, the tooth plate is meshed and connected with the first gear on the left, and the tooth plate is not meshed and connected with the first gear on the right, thereby causing the left side body position conversion plate to rotate around the third rotating shaft, thereby realizing the turning of the other side of the patient to realize the body position conversion, therefore, when the patient needs to turn over, he can adjust according to demand. The turning direction increases the practicability of the device; by setting up a moving mechanism, the right side body position conversion plate is rotated to realize turning the patient on one side to realize body position conversion, preventing the patient's heavy weight, which often requires several nurses or family members to work together to complete, which is time-consuming and labor-intensive. It is convenient for checking the patient or changing the dressing, while the head and neck pillow moves upward to synchronously support and protect the patient's head and neck, making the patient's turning process more comfortable, and avoiding the situation that the blood flow rate in the neck slows down due to the lack of a support point during the turning process, resulting in numbness and discomfort; by setting up a protective mechanism, the right side body position conversion plate is realized The position conversion plate rotates to realize turning the patient over on one side to realize position conversion, to prevent the patient's heavy weight from often requiring the cooperation of several nurses or family members to complete, which is time-consuming and labor-intensive, and is convenient for examining or changing the patient's dressing, and the head and neck pillow moves upward to synchronously support and protect the patient's head and neck. At the same time, the protective plate on the left moves upward to realize protection for the patient when turning over, making the turning process more convenient, avoiding the situation where the patient turns over too much and falls under the bed, and improving the safety of the device; by setting up a massage mechanism, the position conversion plate on the right is rotated to realize turning the patient over on one side to realize The body position change can prevent the patient from being overweight, which often requires the cooperation of several nurses or family members to complete, which is time-consuming and labor-intensive. It is convenient for examining or changing the dressing on the patient, and the head and neck pillow moves upward to support and protect the patient's head and neck synchronously. The protective plate on the left moves upward to protect the patient when turning over. At the same time, the rolling massage head on the right moves back and forth to perform a reciprocating rolling massage on the patient's back, preventing the patient from feeling uncomfortable due to slow blood circulation in the back caused by lying flat on the bed for a long time. The present invention has a simple and reliable structure, a good auxiliary effect on the patient's body position change, is easy to control, and is suitable for promotion.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
