Description

Medical nursing bed

Technical Field

The invention relates to the technical field of nursing, in particular to a medical nursing bed.

Background

Medical care beds, which are divided into electric care beds and manual care beds, are hospital beds used for patients with mobility disabilities in hospitalization or at home. The main purpose is to facilitate nursing of nursing staff and recovery of patients.

The existing medical care bed only adjusts the angle of the backrest of the care bed, but the existing care bed has certain defects, such as: the lying-in woman in caesarean section has a wound on the body, and the caring personnel can help the turning over and move to easily perform secondary injury on the wound, so that the lying-in woman needs to turn over by himself, and the lying-in woman in caesarean section is in a completely weak state at the moment and is difficult to turn over by himself. Meanwhile, when the backrest rises, the human body easily slides downwards, and the lying-in woman can move towards the backrest for comfort and is difficult to move.

Disclosure of Invention

The invention aims to provide a medical care bed to solve the problem that a weak caesarean section parturient is difficult to move and turn over.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a medical care bed, includes rectangular skeleton and lathe bed and rotates the back of being connected with the lathe bed, and the lathe bed is installed on the skeleton, and the lathe bed constitutes the bed body with the back, still including the elevating system who is used for the lift back, its characterized in that: a driving mechanism for driving the bed body to incline is arranged below the bed body, and a labor-saving mechanism driven by the lifting mechanism is arranged on the framework; the lifting mechanism comprises a rotating shaft, a pushing shaft and a first hydraulic cylinder, one end of the rotating shaft abuts against the backrest, the other end of the rotating shaft is hinged to the fixed shaft, the first hydraulic cylinder is fixed on the fixed shaft, and the pushing shaft which abuts against the rotating shaft is fixed on an output shaft of the first hydraulic cylinder.

The principle and the beneficial effects of the invention are as follows:

(1) under the condition that the lying-in woman is weak and difficult to climb to the bed, the driving mechanism can be started, and the driving mechanism drives the bed body to incline downwards, so that the height of the bed body is reduced, the lying-in woman can be enabled to sit on the nursing bed, and the physical consumption of the lying-in woman can be reduced. Therefore, a lying-in woman in caesarean section can be carried to the nursing bed without a nursing staff, so as to avoid secondary injury to the wound. When the lying-in woman needs to turn over, the bed body can be driven to incline through the driving mechanism, so that the lying-in woman is assisted in turning over, and the aim of saving labor is fulfilled.

(2) When needing to adjust the back, start elevating system, elevating system can drive the back and rotate towards the top, reaches the purpose of adjusting, and the back makes the lying-in woman slide towards one side of lathe bed this moment, need move towards one side of back for comfortable lying-in woman, because the lying-in woman of this moment is too weak, can't oneself remove. When the backrest is lifted, the labor-saving mechanism can be held by a puerpera, and the lifting mechanism can push the puerpera to move towards one side of the backrest, so that the aim of saving labor of the puerpera is fulfilled.

To sum up, the rotation of back can be realized to traditional nursing bed, can not help the weak patient of physical strength to stand up or remove because the reason of design, and this application comes laborsaving to patient through actuating mechanism, laborsaving mechanism, especially just dissects lying-in woman of gynaecology, can also avoid causing the secondary damage to their wound.

Further, be provided with the fixed axle on the skeleton, elevating system includes pivot, promotes axle and first pneumatic cylinder, and pivot one end offsets with the back, and the pivot other end is articulated with the fixed axle, and first pneumatic cylinder is fixed on the fixed axle, is fixed with the promotion axle that offsets with the pivot on the output shaft of first pneumatic cylinder.

Further, the bottom of the lathe bed is also provided with a telescopic shaft, and the fixed shaft is fixed on the telescopic shaft. The telescopic shaft can well support the bed body so as to stabilize the bed body in the tilting process. The fixed shaft is stably fixed on the telescopic shaft so as to achieve the purpose of fixedly supporting the first hydraulic cylinder.

Furthermore, the framework is rotatably connected with a first roller shaft, a driving gear is fixed on the first roller shaft, and a rack meshed with the driving gear is arranged on the pushing shaft. The rack can be driven to move upwards in the process of pushing the shaft to slide upwards, so that the rack can drive the driving gear to rotate, and the resistance formed between the driving gear and the rack enables the first hydraulic cylinder to slowly push the rotating shaft.

Further, laborsaving mechanism includes three handles, and the bottom of one of them handle is provided with the pinion, and the pinion below is provided with rotates the second roller of being connected with the skeleton, is fixed with the driven gear with pinion meshing on the second roller, and the winding has the drive line between first roller and the second roller, and three handle upper ends are connected with the connecting rod to two other handles rotate with the skeleton and are connected. The driving gear can drive first roller and rotate when rotating, and first roller can the winding drive line, and the drive line can drive the second roller and rotate, and the driven gear rotation is driven to the second roller, and driven gear drives pinion rotation to pinion drives the handle and moves towards the back, so promotes the user and moves towards the back, reaches laborsaving purpose.

Furthermore, sliding connection has the drive block on the skeleton, is provided with the push rod between drive block and the first roller, is provided with the elastic component between first roller and the telescopic shaft, the one end and the telescopic shaft fixed connection of elastic component, the other end and the first roller rotation of elastic component are connected. When the driving gear is required to be meshed with the rack, a user pushes the driving block, the driving block drives the push rod to extrude the first roller shaft, and the first roller shaft drives the driving gear to be meshed with the rack; when the driving gear is not required to be meshed with the rack, the elastic piece can pull the first roller shaft to be far away from the rack, so that the driving gear is separated from the rack.

Further, actuating mechanism includes the second hydraulic cylinder and fixes the fossil fragments on the skeleton, and the second hydraulic cylinder is fixed on the fossil fragments to the output shaft of second hydraulic cylinder is towards ground. When the second hydraulic cylinder works, the output shaft of the second hydraulic cylinder is abutted to the ground, the reaction force on the ground pushes the lathe bed to turn upwards, and the telescopic distance of the output shaft of the second hydraulic cylinder is manually adjusted, so that the turning degree of the lathe bed is adjusted.

Furthermore, an extension rod is fixed on an output shaft of the second hydraulic cylinder, and an anti-skid block used for preventing the framework from skidding is arranged at the bottom of the extension rod. The extension rod prolongs the stroke of the output shaft of the second hydraulic cylinder, and the antiskid block prevents the framework from skidding.
