Description

Getting up and side protecting linkage type medical nursing bed

Technical Field

The application relates to a medical nursing bed with the function of assisting nursing for the treatment of a patient lying in bed, in particular to an improved mechanism for changing the posture of the patient lying in bed for the patient with weak body.

Background

The medical care bed can assist the bedridden patients to change postures of rising, sitting, leg lifting or double-side recumbent and the like, move the patients or facilitate medical operation of medical care personnel. Most of the existing nursing beds adopt the upper half bed surface to integrally turn over to assist patients to sit up, and for some patients with weak bodies or pain and difficulty in self-holding, the bodies of the patients can sideslip and incline along the upper half bed surface in the sitting up process, so that further physical injuries are easily caused.

Patent document CN206261759U discloses a solution, in which the upper bed plate is divided into a main plate and a two-side plate splicing structure, and when the main plate is turned up, two drivers respectively drive the two side plates to turn upwards symmetrically relative to the main plate, so as to prevent the body from sliding sideways when the patient gets up. The driving structure is complex, the cost is high, and the maintenance cost is high.

Disclosure of Invention

The invention aims to simplify the structure, realize the simultaneous completion of rising and lateral protection linkage by only using single driving power and avoid the lateral slipping of a patient, and provides a rising and lateral protection linkage type medical care bed.

The application provides a get-up side-protection coordinated type medical care bed technical scheme, its main technical content is: a side-protection linked medical nursing bed for getting up comprises an upper bed surface hinged with a lower bed surface, wherein the upper bed surface is composed of a main bed plate and side bed plate hinges at two sides of the main bed plate; the side-turning linkage mechanism comprises a rolling arm, a rolling rail and a supporting crank of the rolling rail, wherein the rolling arm is a cantilever with an outer end provided with a roller, the inner end of the cantilever is fixed on the lower bed surface, and the roller end extends towards the lower part of the main bed plate; the support crank is fixedly installed on the bottom surface of the side bed plate and extends to the lower part of the main bed plate, the outer end of the support crank is fixed by the rolling rail, and when the main bed plate is turned over, the upper roller of the rolling arm presses and pushes the side bed plate to synchronously turn over relative to the main bed plate when the rolling rail runs.

Preferably, in the above-mentioned whole technical scheme, the rolling rail is arranged in a manner that one end of the rolling rail, which is far away from the side bed plate, is inclined from high to low compared with the end of the rolling rail, which is close to the side bed plate.

The utility model discloses a side of standing up protects coordinated type medical care bed technical scheme has realized only by the main bed board of single drive power linkage drive, fall the upset, the side bed board is synchronous to be turned up, the technical purpose who falls back, the side bed board is turned on one's side at further big corner in the main bed board upwards overturns to having blockked the disease and having stood up and sideslipped, the contained angle that forms between side bed board and the main bed board becomes disease side direction lean on the back in addition, can let the disease state of standing up more comfortable. Compared with the prior art, the technical scheme has the advantages that the whole structure is simplified, and the manufacturing cost and the operation cost are lower.

Detailed Description

The following description is given by way of example of a specific configuration for better understanding of the technical solution of the present patent application, and the scope of protection of the present patent application is not limited by the present embodiment.

The lifting side-protection linkage type medical care bed comprises a bed surface supporting frame 1, and an upper bed surface 3 and a lower bed surface 2 which are connected through hinges are laid on the bed surface supporting frame 1 to form an integral bed surface.

The upper bed surface 3 is formed by a main bed plate 30 and side bed plates 31 at two sides of the main bed plate 30 which are connected through hinges. The rising driver 20 adopts a pneumatic push rod, one end of the pneumatic push rod is hinged on the bottom frame of the lower bed surface 2, and the end of the push rod is hinged on the bottom frame of the main bed plate 30 and is used as the driving power for the main bed plate 30 to rise and fall and turn over in a reciprocating manner.

As shown in fig. 2, the side turning linkage mechanisms are arranged at the splicing positions of the main bed plate 30, the lower bed surface 2 and the side bed plates 31, and the side turning linkage mechanisms of the two side bed plates 31 are symmetrical.

The side-turning linkage mechanism comprises a rolling arm 4, a rolling rail 6 and a supporting crank 5 which extends from a side bed plate 31 to the lower part of a main bed plate 30.

The rolling arm 4 is a cantilever with an outer end provided with a roller 40, the inner end of the rolling arm is fixed on the lower bed surface 2, and the roller end extends to the lower part of the main bed plate 30.

The supporting crank 5 is fixedly installed on the bottom surface of the side bed plate 31 and extends to the lower part of the main bed plate 30, the rolling rail 6 fixes the outer end of the main bed plate, and when the main bed plate 30 is turned over, the rolling rail 6 on the main bed plate 4 is a running guide rail of a roller 40 of the rolling arm 4 and is a guide rail which is pressed by the rolling arm 4 to push the side bed plate 31 to synchronously turn over or fall back relative to the main bed plate 30. As shown in fig. 1, at the moment when the rising actuator 20 pushes the main bed board 30 to turn upwards, the side bed board 31 also starts to turn upwards along with the main bed board 30, the rolling arm 4 is reversed on the lower bed board 2 relative to the side bed board 31 which is turned upwards, the roller 40 follows the rolling rail 6 and presses the rolling rail 6 and the supporting crank 5, so that the side bed board 31 turns upwards relative to the main bed board 30 by the hinge shaft 32 with the main bed board 30, as shown in the dotted line state of fig. 3, the side bed board 31 becomes a guard board for the incremental turning of the two sides of the main bed board 30, thereby preventing the patient from sideslipping; when the rising driver 20 reversely drives the main bed plate 30 to turn back, the rollers 40 reversely move along the roller rails 6, and the side bed plate 31 also rotates along with the rollers until the main bed plate 30 is on the same water surface. The roller rail 6 is a guide rail of the roller 40 in this motion.

The distance between the fixed point of the supporting crank 5 and the hinge shaft 32 is designed according to the lever principle so as to meet the requirement of proper side bed plate overturning moment.

In practical design, in order to enable the side bed board 31 to be overturned in an increased range when the main bed board 30 is overturned at the same speed, the end a of the rolling rail 6 far away from the side bed board 31 is inclined from high to low compared with the end B close to the side bed board 31.
