Description

Adjustable positioning and support cool aid

The invention relates to an assistive device, in particular to a cool-sensing assistive device which can adjust the user's limbs, support position and cool down during use.

"Assistive devices" are assistive devices used to improve, monitor, or maintain personal medical status; excluding assistive devices that can only be used by health care professionals. Assistive devices include home assistive devices, personal mobility aids, personal medical aids, personal care and protection aids, orthotics and prosthetics, visually impaired assistive devices, hearing impaired assistive devices, and many more. With more and more cases of long-term or chronic illness in bed, for long-term bedridden patients, medical staff, caregivers or family members need to flip the patient's limbs at any time for treatment or treatment. When turning over a patient, an assistive device will be placed on the side of the patient to support the patient's limbs. Most of these assistive devices are pillows or cushions. Please refer to Figure 1, a user 11 is lying on a bed 12 On the side of the user 11, a pillow-like assistive device 13 is placed. When the user 11 is to turn over or turn him on his side, the assistive device 13 is placed on the side of the user 11 to The assistive device 13 is used as a center to turn the user 11 away from one side of the user 11 away from the assistive device 13. At this time, the assistive device 13 bears against the chest of the user 11 and supports the hands and feet of the user 11. Allow medical personnel or caregivers to perform actions such as medical treatment, physical therapy, massage or wiping.

"Position", English position, that is, "position". The main role of correct positioning is to improve the distribution of body weight, reduce the occurrence of pressure ulcers, promote the relaxation of spasm muscles, and Patients with damage are a kind of tension control treatment, and correct bad posture to avoid deformity and secondary injury. In order to avoid complications in bedridden patients and to promote physical function recovery, doctors will specifically instruct patients to set up a specific position. For patients with neuromuscular system damage or third-degree burns, they cannot maintain their position autonomously, so external support is needed to achieve the effect of pulling, and positioning aids can help achieve this. Features.

In addition to the aforementioned patients, healthy people will also adjust their posture through the positioning aids, such as placing the positioning aids on the tail spine when lying down to sleep, to reduce the pressure on the lumbar spine, etc .; The positioning aids are separated so that the legs extend parallel to the hip joint and reduce the twist of the hip joint.

However, most of the aforementioned aids are general pillows or cushions, and these materials are mostly cotton, linen, or synthetic fibers. These materials do not have the function of cooling and ventilating, and will accumulate body temperature over a long period of time. If they are used for users with mobility difficulties or unable to move autonomously, they may sweat for a long time, which may cause sweat rash or rash.

In addition, it is known that the overall hardness of the assistive device is the same. If the medical staff wants to raise a certain part of the device properly, it is necessary to increase the number of the assistive device at a relative position, or to place other harder material under the assistive device to lift the device. The height of the corresponding limb is high, and the positioning cannot be accurately achieved, which is inconvenient.

For this reason, therefore, how to solve the above problems is the subject that the industry-related players are eager to study.

The purpose of the present invention is to provide an assistive device that can adjust the position or support the height of the user's abutting position, and can use different supporting surfaces of the assistive device according to the use environment temperature, so that the user feels comfortable.

In order to achieve the above purpose, the technical means is that the assistive device has a multilayer stacked symmetrical structure, which includes: a cool feeling layer, a hard layer and a soft layer, wherein the cool feeling layer has the functions of cooling, anti-sliding and pulling, When a user's limb is placed on the cool feeling layer of the assistive device, the cooling effect will be achieved through the cool feeling layer; when the user's limb is placed on the soft layer, the hardness of the soft layer is lower than the hard layer Therefore, the position of the limb will be lower than that placed on the cool-sensing layer, so that the medical staff can adjust the use surface of the assistive device according to the purpose.

Another object of the present invention is to increase the support and elasticity of the assistive device. By providing a C-shaped frame in the assistive device, the internal stress of the C-shaped frame is used to support the user's limb, and the C-shaped frame is supported by the C-shaped frame. The frame has an open end that expands elastically, and increases the elasticity of the support of the assistive device when the limb is pressed down, further achieving the functions of adjusting limbs, fixing, supporting the limbs, avoiding wounds, and making it easy for medical staff to clear sores.

Still another object of the present invention is to provide the assistive device for fixing limbs and strengthening the supporting function. The technical method is to set a plurality of accommodation spaces in the assistive device. When the user's limbs are pressed on the accommodation spaces, the The inner fillings of the assistive device, such as the cool-sensing layer, hard layer or soft layer, are pressed into the accommodating spaces by the pressure of the lower limbs, and are supported by the edge of the accommodating space to fix the limbs. Further, a filler having a hardness greater than that of the hard layer may be built into the accommodating spaces to support the lowered limb to achieve the function of strengthening support.
