An anti-decubitus mattress

Abstract

The invention relates to the technical field of mattresses, in particular to an anti-decubitus mattress for medical care and daily household care, including a base pad, on which a back air cushion positioning groove and a buttock air cushion positioning groove are opened, and the back air cushion positioning groove A back air cushion is provided inside, and a buttock air cushion is provided in the buttock air cushion positioning groove. The area of ​​the back air cushion positioning groove and the buttock air cushion positioning groove is surrounded by the remaining area of ​​the base pad, and the remaining area is partly used as the base pad. The cushion area of ​​the base cushion is divided into the head and neck cushion area, the back cushion area, the buttocks cushion area and the leg and foot cushion area successively from the head of the bed to the end of the bed along the direction of the bed. The back air cushion and the buttocks air cushion are connected with The control device has a firm structure, durability, comfort and better anti-decubitus effect.

Description

technical field [0001] The invention relates to the technical field of mattresses, in particular to an anti-decubitus mattress for medical treatment and household daily care. Background technique [0002] Bed sores, that is, pressure ulcers and pressure sores, are due to the long-term pressure on the local tissues of the patient, which affects blood circulation, resulting in continuous ischemia, hypoxia, and malnutrition in the local skin and subcutaneous tissue, resulting in tissue ulceration and necrosis. It is a common problem in treatment and nursing. Clinical manifestations include erythema, numbness, pain, ulceration, necrosis, and ulceration in the compressed area. Some of them have systemic symptoms or even sepsis due to local infection. Patients who need to stay in bed for a long time or those who are humid, high fever, and obese are prone to bed sores. It is difficult for ordinary mattresses to prevent these people from giving birth to bedsores, and it requires...

Problems solved by technology

[0008] In the above technical solution, by slotting the base cushion at the middle position, the back air cushion and the buttocks air cushion are at the middle position, the overall structure of the base cushion is less affected, and the strength and stretch can be guaranteed. At the same time, because the air cushion Installed in the groove, in fact, it is not easy to cause problems such as translocation between the various layers in the base cushion. In addition, this structure can release more gas in the air cushion when the mattress is not in use. Just keep a small amount, which can effectively solve the problem that the air cushion is in a relatively full expansion state for a long time due to the long-term effect of more gas inflated in the air cushion, which will cause premature fatigue of the air cushion and affect the later use effect. When a child Or when guests or people are tired and sit directly on the bed or lie on the bed and other sudden use situations occur, due to the four peripheral areas of the head and neck cushion area, the back cushion area, the buttocks cushion area and the leg and foot cushion area, it can Effectively play the role of cushioning the large initial impact force and the pressure sharing during the down-pressing process, avoiding damage to the internal structure of the air cushion that is not filled with enough air and the friction and shearing forces on the human body. However, the upper part of the general base pad is basically a combination of flexible and elastic material layers such as sponge layers, and the human body will still sink. Through the control of the control device, such as a pressure sensor, when it reaches a certain level The pressure value, the air pump can automatically inflate, so that the air cushion is filled with an appropriate amount of gas, so that the human body can lie comfortably on it. If you want to be more comfortable and anti-decubitus, you must control the air cushion and the posture of the human body to complete it. Of course, this process The optimal realization is based on the fact that the highest position of the air cushion in the initial state is lower than the highest positions of the head and neck cushion area, the back cushion area, the hip cushion area and the leg and foot cushion areas, so as to achieve better cushioning and Due to the effect of partial pressure, the head and neck cushion area, back cushion area, buttock cushion area and leg and foot cushion area are essentially connected together as a whole, with good flatness, and because the initial position of the air cushion is lower, when After the base cushion is covered with a bed cover or one side of the fabric layer is sewn, it still looks like a relatively flat mattress structure, which is beautiful and practical. Although the cushion area and the leg and foot cushion area are raised to a certain height when the air cushion is inflated, as long as the original height is sufficient, part of it can still be divided. Here mainly refers to the head and neck cushion area and the leg and foot cushion area, while the back and buttocks It is the air cushion support of the backrest air cushion positioning groove and the hip air cushion positioning groove. The force is basically on the air cushion. The back cushion area and the buttock cushion area are located on both sides of the human body in normal use, and the effect is small. Only the outer positions on both sides will have the pressure-bearing effect. In addition, ordinary mattresses, whole bed air mattresses or mattresses with more air cushions in the prior art, due to the curve of the human body itself, in fact, when people When lying flat, the main supporting parts are the buttocks and most of the back. The head is mainly supported by the pillow, and the legs and feet are less supported. Moreover, these two parts are unlikely to develop bedsores. Therefore, there are problems such as unreasonable air cushion design in existing mattresses, failure to achieve better comfort, and inability to effectively prevent bedsores. Of course, it can be improved by increasing the height of the head and tail of the bed, consuming air cushions, etc., but these methods are harmful to the bed. The structure, integrity, and aesthetics of the mattress will have a great impact, which is not conducive to production, sales, and use. The head and neck cushion area and the leg and foot cushion area of ​​the mattress structure are combined with flexible and elastic materials. When forming a soft layer, through the cooperation with the positional relationship of the air cushion, it can achieve the comfort of the head, neck, legs and feet and a certain partial pressure effect, and can also improve the comfort of the back and buttocks and effectively prevent the problem of long bedsores
