Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology and relates to a mattress. Background Technology

[0002] With the increasing aging of the population, the health care of the elderly is receiving growing attention. Elderly people who are bedridden for extended periods are prone to complications such as pressure sores due to limited physical activity. Mattresses equipped with pressure monitoring functions (the mattress itself plus a corresponding controller) can promptly detect changes in the elderly person's position and abnormal pressure distribution. Caregivers can adjust the elderly person's position immediately based on the detected pressure anomalies to prevent pressure sores and other complications.

[0003] For example, patent application number CN201910132957.4 discloses a smart health and wellness mattress based on a flexible pressure sensor array. It includes a sensing layer (composed of a flexible pressure sensor array to detect pressure signals on the upper surface), a support layer (supporting the human body), an execution layer (adjusting shape), and a controller (connecting the sensing layer and the execution layer to control monitoring and deformation). It can change its surface shape according to pressure distribution, allowing the user to maintain a healthy pressure distribution in any sleeping position. However, such mattresses are often multi-layered composite structures formed by bonding different layers of fabric. Because each layer of the mattress has different tensile properties, the mattress is prone to delamination during use, causing the sensors on the mattress to shift and resulting in inaccurate pressure monitoring results.

[0004] Therefore, it is necessary to propose a mattress to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and to propose a mattress.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mattress is made of spaced fabric, comprising, from top to bottom, a surface knitted layer, a middle support layer and a bottom knitted layer. The surface knitted layer consists of a non-pressure sensing area and a pressure sensing area. The pressure sensing area is woven together with conductive yarn and insulating yarn, and the non-pressure sensing area is woven with insulating yarn.

[0008] When a person lies on a mattress and comes into contact with the pressure sensing area, the coil made of conductive yarn in the pressure sensing area deforms under pressure, causing the coil's resistance to change. The greater the rate of change in the coil's resistance, the greater the pressure the coil experiences.

[0009] As a preferred technical solution:

[0010] As described above, the conductive yarn is silver-plated nylon multifilament, and the insulating yarn is one or more of polyester multifilament, nylon multifilament, and spandex multifilament.

[0011] As described above, the conductive yarn has a count of 44-77 dtex, and the insulating yarn has a count of 90-150 dtex.

[0012] In the mattress described above, the conductive yarns in the surface knitted layer are woven into a warp satin weave, a warp plain weave, or a warp twill weave, while the insulating yarns are woven into a double warp plain weave, a warp pile plain weave, or a warp twill plain weave.

[0013] In one type of mattress as described above, the ends of the conductive yarns are hidden within a non-pressure sensing area.

[0014] As described above, in a mattress, all pressure-sensing areas are distributed on the contact areas between the head, shoulders, back, waist, hips, thighs, calves, and heels of the body when the body lies flat on the mattress.

[0015] As described above, the middle support layer of this mattress is woven from spacer yarns, which are polyester monofilaments with a count of 30-50 dtex.

[0016] As described above, the bottom knitted layer of this mattress has a mesh structure. Existing mattresses, due to limitations in the sensor structure itself, have poor breathability, easily causing localized stuffiness and discomfort, which actually increases the risk of pressure sores. The mattress of this invention has an overall woven structure, with a mesh knitted layer at the bottom, providing excellent breathability and reducing the likelihood of localized stuffiness and discomfort, thus lowering the risk of pressure sores.

[0017] In one type of mattress as described above, the bottom knitted layer is woven from the insulating yarn.

[0018] The mattress described above has a thickness of 3-5cm.

[0019] The mattress of this invention can be connected to controllers in the prior art. These controllers have different functional modules and can perform different functions based on pressure monitoring. For example, they can issue an alarm message after the pressure exceeds a certain value or the pressure duration exceeds a certain duration; they can also generate personalized pressure maps based on historical pressure information to help optimize care plans.

[0020] Beneficial effects:

[0021] The mattress of this invention has an integral woven structure, and the pressure sensing area (sensor) on the mattress will not shift, thus avoiding the problem of inaccurate pressure monitoring caused by sensor displacement. Attached Figure Description

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0027] A type of mattress, made of spacer fabric, such as Figures 1-3 As shown, from top to bottom, it includes a surface knitted layer 1, a middle support layer 2, and a bottom knitted layer 3;

[0028] The surface knitted layer 1 consists of a non-pressure sensing area 4 and a pressure sensing area 5.

[0029] The pressure sensing area 5 is woven together by conductive yarn 6 and insulating yarn 7, and the non-pressure sensing area 4 is woven by insulating yarn 7; wherein, the conductive yarn 6 is woven into a warp satin structure, a warp plain structure, or a warp twill structure; the insulating yarn 7 is woven into a double warp plain structure, a warp pile plain structure, or a warp twill plain structure.

[0030] The end of the conductive yarn 6 is hidden in the non-pressure sensing area 4; all the pressure sensing areas 5 are distributed in the contact areas between the head, shoulders, back, waist, buttocks, thighs, calves and heels and the mattress after the human body lies flat on the mattress.
