Description

  The present invention relates to a synthetic resin bathtub wheelchair for use in a hospital with a wheelchair slope facility, a nursing facility, a pool in a hotel or leisure facility, and a large bath in a hot spring inn.

  As a conventional method of bathing a care recipient who needs care, a lift device or a hydraulic device is used to lift or move the body of the care recipient, which is accompanied by the caregiver. Helping you to bathe by helping and operating in a wet state. However, the operation of these devices requires skilled operation techniques and careful consideration for the caregiver, while the psychological burden that the care recipient needs to be lifted and moved by the machine should be limited. He was very anxious about the dangers.

  Moreover, as a method for safely bathing an elderly person who is bedridden, a suspension type moving device that moves an inconvenient body with an auxiliary device such as a belt or an arm is provided, but the device itself is large and expensive. In addition, there is a problem that the bathroom itself has to be remodeled in order to secure a space where the suspension type moving device can be operated.

  Conventionally, care devices and wheelchairs that attempt to solve such problems have been proposed. For example, an elderly person who is bedridden, etc. who needs a caregiver whose neck has become unstable can be safely bathed with the assistance of one person, is inexpensive, easy to handle, and does not require remodeling of the bathroom. A “bathing assistance device” (Patent Document 1) for a person is proposed and has become a publicly known technique.

  However, the proposal of the “bathing assistance device” is composed of a neck support device that is placed under the neck of a bather who needs care, such as a bedridden elderly person, and a fixing device that is fixed at the back of the bather. The device is formed by covering an air float formed in a U-shape for fitting a neck under the chin with a cloth bag in consideration of the touch. The fixing device is placed behind the bather (care recipient) and consists of an adsorbing anti-slip mat placed on the inner surface of the bathtub and a connecting material. A proposal of an auxiliary device that is connected to a neck support floating device arranged underneath so as to be adjustable in length, and the proposal is based on a bather who needs care such as a bedridden elderly person while taking a bath. However, there are problems that the bedridden elderly cannot move before and after bathing, and that the rehabilitation exercise cannot be performed by the bather himself during bathing.

  In addition, a “wheelchair bathtub” (Patent Document 2) that can be easily prepared by a person using a wheelchair as easily as possible while taking a bath as much as possible has been proposed and has become a publicly known technique.

  However, the proposal of the “wheelchair bathtub” is that a rectangular bottom plate is provided, and the waterproof sheet is spread so as to cover the bottom plate and its periphery around the bottom plate, and the sheet on the bottom plate is expanded. Mount the wheelchair, lift the four corners of the seat, and assemble side frames upright on the four edges of the bottom plate, around the seat with the corners lifted, and assemble the outer frame integrated with the bottom plate A space on the sheet that is formed by a sheet that is freely formed and that is configured to hang the sheet by suspending the edge of the sheet to a locking portion provided on the upper portion of the outer frame, and suspending the edge. A proposal for a bathtub that can be bathed in a wheelchair with hot water inside, and the proposal is simply a proposal for a bathtub in which an existing wheelchair can be entered, so that the structure of the wheelchair can be immersed in hot water With Rather than shall, malfunction during wheelchair flooding safety, rust was achieved, there are many problems in terms of Mentenasu management.

  In addition, when there is a physical activity disorder such as the elderly and it is difficult to take a normal bath, the hard work of the assistant and the pain of the sensitive nerves caused by the existing mechanical means and actions to enter the bathtub, and the fear of the disabled "Chair Bath" (Patent Document 3) is proposed that can improve the bathing environment by eliminating labor and improving labor efficiency and efficiency in facilities, etc., and also improving the current difficult state even at home bathing It is a known technique.

  However, the proposal of the “chair bath” is a mechanism in which a bathtub is rotatably supported by a support shaft on a movable carriage, and the upper surface of the bathtub can be fixed horizontally and in an angle range of about 45 ° forward tilt angle. And a chair bath provided with a guide groove or a guide rail inside the bathtub so that the seat is pulled out forward when the vehicle is moved forward. Because it is a proposal for a chair bath specializing in bathing specifications rather than in the specifications of the bath, it can be used for the cost burden of the introduction price, the pool of hospitals, nursing homes, hotels and leisure facilities, and large baths of hot spring inns It does not have an appropriate structure, and there is a problem that a dedicated space or a troublesome transportation means is required for storage and transportation means. It was.

  The present applicant pays attention to the structure of the wheelchair for bathing and the bathing means in the above, and is based on the idea that it is not possible to provide a wheelchair in which a care recipient can enjoy bathing for bathing or rehabilitation exercise. Developed a synthetic resin bathtub wheelchair for use in hospitals with wheelchair slope facilities, nursing facilities, hotel and leisure facilities pools, and large baths in hot spring inns. It leads to.
