technical field

The invention relates to a multifunctional nursing bed, in particular to a multifunctional wheelchair bed which can realize the function of wearing and taking off pants while sitting.

Background technique

Nursing beds are mainly used for the care of disabled and semi-disabled people such as the elderly, disabled patients, bedridden patients, etc. A wheelchair bed is a special nursing bed that combines a bed and a wheelchair, combining the functions of a nursing bed and a wheelchair. The chair separation function expands the living space of the care recipients. Nursing beds in existing markets at home and abroad, especially wheelchair beds, have similar functions and a single structure, and are already in a bottleneck period. More new functions are needed to break this bottleneck and meet the higher-level needs of such people.

The Chinese invention patent application with publication number CN110693653A discloses an auxiliary device for putting on and taking off pants, which can realize the function of assisting putting on and taking off pants, but it realizes the function of assisting wearing and taking off pants while standing. For bedridden patients, its applicable ability is poor.

SUMMARY OF THE INVENTION

In view of the deficiencies in the prior art, the present invention provides a wheelchair bed that can realize the function of wearing and taking off pants while sitting. In addition to the second stool treatment and auxiliary nursing, the function of sitting on and taking off pants can be realized.

In order to achieve the above purpose, the present invention provides the following technical solution: a wheelchair bed that can realize the function of putting on and taking off pants. It includes a bed body, a wheelchair, a bed board, a waste disposal device, an auxiliary device for putting on and taking off trousers, a synchronous translation device, and a separation structure for people and chairs. The wheelchair part can be separated from the bed body, and each bed board can be hinged to realize the posture change of back up and side body. The second stool treatment device adopts an inflatable hip plate, which is completely within the wheelchair frame, which can effectively carry out the second stool treatment; auxiliary The device for putting on and taking off pants is connected to the bed body through micro slides and distributed on both sides of the middle part, so that the function of putting on and taking off pants while sitting can be realized.

Further design, the bed body needs to be divided into three parts, one part needs to be combined and separated from the wheelchair, one part needs to be connected with the auxiliary bed trousers removing device, and the other part needs to be connected with each bed board.

Further, the central fixed bed board is fixedly connected with the bed body, the central transition bed board is hinged with the fixed bed board, the left and right back bed boards are hinged with the center transition bed board, the left and right side body bed boards are hinged with the central fixed bed board, and finally the left and right back bed boards are connected with the left and right side body boards. The bed boards are connected separately.

Further, the tail of the electric actuator with a stroke of 200mm of the model LX600 is fixed on the bed body, the head and the side bed are connected through the electric actuator bracket, and there is an electric actuator on the left and right sides.

Further, the tail of the electric actuator of model LX600 stroke 250 is fixed on the bed body on one side of the central fixed bed, and the head is connected with the central transition bed.

With this design, the posture changes of back up and sideways can be realized.

Further design, the bed body needs to be combined and separated from the wheelchair. The bed body is combined and separated from the wheelchair through the drawer guide rail, and is equipped with an electromagnet with a suction force of 60KG. When the power is turned on, the wheelchair is fixed on the bed body. Bed and chair separation is possible.

In a further design, the auxiliary bed trousers removing device is installed on the bed body through a micro slideway, which can slide on the bed body, and a pair of auxiliary bed trousers removing devices are distributed on both sides of the left and right middle bed boards.

Further, the synchronous translation device includes a positive and negative screw, a screw nut, a nut conversion seat, a hand wheel, a connecting rod, and a bearing seat. The pair of bearing seats are symmetrically fixed on the bed, and the positive and negative screw Fixed on the bearing seat, a pair of screw nuts and the nut conversion seat are symmetrically connected to the positive and negative screw rods, and a pair of connecting rods are respectively connected with the auxiliary wearing and taking off devices on both sides and the nut conversion seat on both sides, and the handwheel is fixed.
