Abstract
Description
[0001] TREATMENT TABLE WITH INTEGRATED BATHTUB
[0002] TECHNICAL FIELD OF THE INVENTION
[0003] The present invention relates to the technical field of mechanical engineering, electronics, health care and more specifically nursing, since it provides a stretcher with an integrated bathtub.
[0004] BACKGROUND OF THE INVENTION
[0005] The operational challenges inherent in managing and maintaining the hygiene of patients with reduced mobility in hospital and healthcare settings are significant. Personal hygiene and bathing for these patients are fundamental to preserving their health and well-being. However, traditional bathing methods often require repeatedly moving the patient, which can be uncomfortable and stressful for them, as well as laborious and time-consuming for healthcare staff. The use of water-resistant and durable materials, such as stainless steel, high-strength plastics, and waterproof finishes, has been key in the development of these bathing beds. Ergonomic and adjustable designs improve user comfort and therapist efficiency.
[0006] The evolution of treatment tables with integrated bathtubs reflects the growing demand for wellness treatments and the integration of technologies in the health sector.
[0007] In the mid-20th century, advances in materials and industrial design led to the integration of different functions into healthcare equipment. The emergence of modern hydrotherapy spurred the creation of devices that combined water therapy with the comfort of a treatment table. In recent decades, the growing demand for personalized rehabilitation, health, and wellness treatments has driven the development of treatment tables with integrated bathtubs. These devices offer a comprehensive treatment experience, combining massage, hydrotherapy, and other services in a single unit.
[0008] Modern treatment tables can include a variety of additional features such as hydromassage systems, water heating, electronic controls, and automatic table position adjustments. These advancements allow for personalized treatments tailored to each patient's specific needs.
[0009] Today, treatment tables with integrated bathtubs are common in health centers and physiotherapy clinics. They offer a comprehensive solution for wellness treatments, combining the relaxation and therapeutic benefits of water with other therapies. These tables represent the intersection of health, wellness, and technology, providing complete solutions for modern treatments.
[0010] A prior art search was conducted for stretchers with integrated bathtubs, revealing that various stretchers have been developed for this purpose, as mentioned in United States Patent Application No. US3755830 (11), dated September 4, 1973, entitled "PORTABLE BATHTUB," which describes a portable bathtub having a frame portion, a lining portion, and leg portions that facilitate the use of the bathtub on a carrier surface, such as a stretcher. The frame includes a horizontally arranged open center member formed by a plurality of telescopic parts. The dimensions of the open center of the frame are larger than the carrier surface.The legs are pivotally attached to the frame, and at least two of the legs are contoured so that, by turning them, the lower support end can be placed in different lateral positions. Thus, by placing the legs inwards, the tub can rest on a stretcher, and by placing the legs outwards, the frame can be lowered below the carrier surface with its lining, covering the carrier surface and the frame and leg parts hanging off the sides, thus providing a flush surface over the carrier to facilitate the movement of patients over the carrier surface.
[0011] The document cited above refers to a portable bathtub, but shows no evidence of having wheels integrated into the structure itself, which would allow it to be moved without the need for any additional element, nor does it describe having a door which is hinged, which allows the user to enter without difficulty.
[0012] The aforementioned document does not show evidence of having a lifting mechanism which allows adjustment to the user's height to facilitate entry and subsequently adjust to the height of the person responsible for assistance during bathing.
[0013] Also found was a document from a publication on a website which refers to "SHOWER AND BATH CARTS" that allows for safe and easy showering and patient transfers with the Pacific Electric Hi Lo shower cart, which describes a bathtub that features fully electric controls, a load capacity of up to 200 kg, sides of the bathtub that lower to be level with the patient platform, high-performance LINAK and TENTE components with 125 mm wheels which are corrosion resistant, height adjustment for work performance, a unique seamless deep bathtub design that is easy to clean and allows for a soft-touch fabric immersion bath, a 24 VDC system with a wall-mounted remote battery charger, a low battery warning light, a waterproof pillow, handles on both ends, a connection plug option for different regions, and optional safety rails.
[0014] The documents cited above do not describe having a backrest with restraint straps to prevent risky movements in the user, nor do they show evidence of having a tilting mechanism in the backrest to position the user at the desired height when inside the bathtub.
[0015] They also do not provide evidence of having installed pipes for the use of water by means of a shower, as well as a container for the subsequent disposal of wastewater.
[0016] OBJECT OF THE INVENTION
[0017] The present invention has as its object to provide a stretcher with an integrated bathtub, which has wheels integrated into its structure for its movement.
[0018] Another object of the present invention is to provide a stretcher with an integrated bathtub, which has a hinged door to facilitate user access. A further object of the present invention is to provide a stretcher with an integrated bathtub, which incorporates a lifting mechanism that allows it to be adjusted to the user's height to facilitate access and subsequently adjusted to the height of the person responsible for assistance during the bath.
[0019] Another object of the present invention is to provide a stretcher with an integrated bathtub, which has a backrest with restraint straps that allow the user to be secured to prevent slipping.
[0020] An additional object of the present invention is to provide a stretcher with an integrated bathtub, which incorporates an adjustment mechanism in the backrest that allows the user's inclination to be adjusted when inside the bathtub.
[0021] Another object of the present invention is to provide a stretcher with an integrated bathtub, which has connections for the supply of water by means of a shower.
