Description

A transfer car for the paralyzed elderly to take a bath

technical field

The utility model relates to a medical nursing device, in particular to a transfer vehicle for the paralyzed elderly before taking a bath, which can be used together with a transfer stretcher and a bathtub.

Background technique

At present, whether it is in a hospital or a nursing home, the elderly who have been paralyzed in bed for a long time must be bathed regularly. However, it is very inconvenient to transfer and bathe these bedridden patients. Most of them can only use body scrubbing instead of bathing, but this is far from satisfactory For the basic needs of elderly skin cleansing. In order to solve the problem of difficulty in taking a bath for the disabled elderly, some new bathing beds and bathing carts have been developed, but the existing bathing carts do not have a lifting mechanism, or cannot realize the transfer function from the nursing bed to the bathroom. The process of disabled elderly is relatively complicated, which not only brings great pain to disabled elderly, but also increases the risk of accidental injury of disabled elderly, and also increases the workload of nursing staff.

Utility model content

According to the technical problems raised above, a transfer vehicle for bathing the paralyzed elderly is provided. The utility model utilizes a support device with a lifting function, which can be pushed from the bathroom to the nursing bed, and then from the nursing bed to the bathroom, realizing long-distance seamless docking; the utility model mainly uses the scissor-type lifting part , with a linear motor as the power, the limit switch of the travel can make the lifting part rise and fall to the required height, and only one nursing staff can complete the transfer work of the disabled elderly in the whole process, so that the disabled elderly It is more convenient to carry and reduce the workload of nursing staff.

The technical means adopted in the utility model are as follows:

A transfer vehicle for the paralyzed old man to take a bath, comprising a base frame, a lifting part set on the base frame part, a support part set on the upper end of the lifting part, and a support part set on the lower end of the support part for controlling the lifting A control unit for the movement of the unit, characterized in that:

The underframe part includes a bottom frame for supporting the overall structure and universal casters fixed at the lower end of the bottom frame, one end of the lifting scissors of the lifting part is connected with the scissor roller slideway arranged inside the bottom frame The other end of the lifting scissors is connected to the support part, the upper end of the support part is provided with a detachable docking guide rail, and the upper end of the support part is also provided with a docking lock locked with the upper external device.

The lifting part is an electric lifting mechanism, which abandons the hydraulic cylinder commonly used in the scissor lifting platform as the power lifting method, and selects the special silent linear motor for medical rehabilitation equipment as the power, which can reduce the noise in the process of rising and falling. Controlled by the control unit, it can be charged repeatedly and used for many times. The required power supply is 24V, which ensures the safety of use. The control part includes a linear motor, a control box, a battery and a control handle. Wherein in order to ensure the safety of the circuit, the battery and the control box are all installed inside the power box, the power box is installed on the upper bracket, and there is a hook outside the power box to facilitate the suspension of the control handle. The installation position of the motor is optimized, the original conventional motor installation position is abandoned, and a new installation position is boldly tried, so that it can be lowered to the lowest position under the basic height requirement of the transfer device, which is convenient for the disabled elderly Transfer of a nursing bed to a transport stretcher.
