Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a neurology nursing bed. Background Art

[0002] Critically ill patients in neurology generally require long periods of bed rest for treatment. Existing nursing beds are generally only used to allow patients to lie flat on them. Since patients have difficulty in moving and are unable to turn over on their own, in order to prevent bedsores and even muscle atrophy caused by patients lying flat or maintaining the same posture for a long time, nurses are required to position and massage patients to turn them over. Existing nursing beds are generally made of a whole bed board. When turning patients over, for critically ill patients with weak mobility, nurses have to rely entirely on the nurses to move the patients' bodies to turn them over. This method makes the nurses very tired, and the entire turning process is time-consuming and laborious, and also makes the patients feel uncomfortable. In addition, in the process of manual turning, it is easy to cause some injuries to the patients due to incorrect force, which is not conducive to their treatment.

[0003] So we need a neurology nursing bed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a neurology nursing bed to solve the problem of difficulty in turning over for neurology patients raised in the above background technology.

[0007] Furthermore, the drive assembly includes a left transmission shaft arranged below the left bed board along the length direction of the bed frame, a right transmission shaft arranged below the right bed board along the length direction of the bed frame, and a drive shaft arranged along the center line of the length direction of the bed frame. The drive shaft is used to drive the left transmission shaft or the right transmission shaft to rotate, and the left transmission shaft drives the left screw to rotate through the left transmission member, and the right transmission shaft drives the right screw to rotate through the right transmission member.

[0008] Furthermore, the left transmission member includes a left driven bevel gear arranged on the left screw and a left driving bevel gear arranged on the left transmission shaft and meshing with the left driven bevel gear, and the right transmission member includes a right driven bevel gear arranged on the right screw and a right driving bevel gear arranged on the right transmission shaft and meshing with the right driven bevel gear.

[0014] Furthermore, the lower movable support group includes a lower screw rod arranged along the length direction of the bed frame, a lower nut seat that cooperates with the lower screw rod for threaded transmission, a lower driven gear arranged on the lower screw rod, and a lower support rod with one end hinged to the lower nut seat and the other end hinged to the rear upper base plate.

[0015] Furthermore, the lower driven gear, the left driven gear and the right driven gear are not arranged in the same plane, and a handle for rotating the drive shaft is provided at one end of the drive shaft close to the tail support.

[0016] In the above scheme, when the patient is lying flat, when the driving shaft is slid to engage the active gear with the left driven gear, the driving shaft is rotated by turning the handle to drive the left driven gear to rotate, and then the left front transmission shaft and the left rear transmission shaft rotate synchronously, so that the left screw rods under the left front bed board and the left rear bed board rotate synchronously, and the corresponding left nut seat moves away from the driving shaft and the left front bed board and the left rear bed board are synchronously flipped to a certain angle through the left support rod to assist the patient lying on the bed board assembly to turn over to the right side; similarly, when the patient is lying flat, the driving shaft can be slid to engage the active gear with the right driven gear and the handle can be turned to drive the driving shaft to drive the right driven gear to rotate, so that the right front bed board and the right rear bed board are synchronously flipped to a certain angle to achieve the purpose of assisting the patient lying on the bed board assembly to turn over to the left side.

[0017] Alternatively, the drive shaft can be slid to engage the driving gear with the lower driven gear, and then the drive shaft can be rotated to move the lower nut seat, thereby forcing the rear upper base plate to flip to a certain angle through the lower support rod, so that the patient is in a backward leaning state on the bed.

[0018] Compared with the existing technology, the neurology nursing bed of this solution has at least the following beneficial effects:

[0019] In this solution, by rotating the drive shaft when it is at different positions along its axial direction, the patient can be assisted to turn over to the left or right side or to be in a resting state leaning back, which is simple and convenient to operate. In this solution, the power source for driving the patient to turn over to the left or right side or to lean back is derived from a single drive shaft. Due to the small number of power sources, the structure of this solution is simple and compact. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 12 As shown, the corresponding left nut seat 4012 moves away from the driving shaft 4033 and synchronously flips the left front bed board 2011 and the left rear bed board 2012 to a certain angle through the left support rod 4013 to assist the patient lying on the bed board assembly to turn over to the right side; similarly, when the patient is lying flat, as shown in FIG. Figure 11 As shown, the slidable drive shaft 4033 enables the driving gear 40331 to mesh with the right driven gear 504 and by rotating the handle 80, the drive shaft 4033 drives the right driven gear 504 to rotate, so that the right front bed board 2021 and the right rear bed board 2022 are synchronously flipped to a certain angle to achieve the purpose of assisting the patient lying on the bed board assembly to turn over to the left.

[0061] The drive shaft 4033 can also be slid to engage the driving gear 40331 with the lower driven gear 406, and then the drive shaft 4033 is rotated to move the lower nut seat 4052 and force the rear upper base plate 302 to flip a certain angle through the lower support rod 4053, so that the patient is in a backward leaning position on the bed.

[0062] Compared with the existing technology, the neurology nursing bed of this solution has at least the following beneficial effects:

[0063] In this solution, by rotating the drive shaft when it is at different positions along its axial direction, the patient can be assisted to turn over to the left or right side or to be in a resting state leaning back, which is simple and convenient to operate. In this solution, the power source for driving the patient to turn over to the left or right side or to lean back is derived from a single drive shaft. Due to the small number of power sources, the structure of this solution is simple and compact.

[0064] The above are only embodiments of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection 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.
