Abstract
Description
Technical Field
[0001] This utility model relates to the field of mattress technology, and in particular to a medical airbag mattress. Background Technology
[0002] A medical bed consists of a rigid bed frame and a bed panel. The bed panel is composed of three parts: a backrest, a seat, and a footrest. It is very suitable for patients who are not easy to move to lie down and receive treatment. The bed can be raised and lowered and can be remotely controlled to allow patients to take care of themselves.
[0003] Chinese utility model patent CN102525768B discloses a medical inflatable mattress that uses a cone-shaped airbag design for the main body airbags. When the odd-numbered rows of airbags and the even-numbered rows of airbags are inflated alternately, a first tilt angle can be provided. With the addition of tilt airbags, when all the main body airbags are inflated and the two tilt airbags are inflated alternately, a second tilt angle can be provided. When the odd-numbered rows of airbags and the even-numbered rows of airbags are inflated alternately and the two tilt airbags are inflated synchronously from left to right, a third tilt angle can be provided. The tilt angle at this time is the sum of the two, which is the maximum tilt angle. In this way, not only can the provided tilt angle be increased, but also a variety of tilt angle combinations can be formed.
[0004] However, the above-mentioned mattress still has some drawbacks:
[0005] The main airbags of the mattress consist of several interconnected airbags forming an airbag row. If this mattress is used on an adjustable medical bed, the airbag row will bend when the backrest, seat, and footrest are raised. During the bending process, the airbag row is prone to relative movement with the bed board, which creates friction and affects the lifespan of the airbags.
[0006] The mattress's airbags are directly encased between the upper and lower covers. The top and bottom surfaces of the airbag array are wavy, creating a strong unevenness when lying on it, resulting in poor comfort. Furthermore, when the body compresses the airbag array, the connection between the airbags is prone to tearing, which also affects the lifespan of the mattress.
[0007] Therefore, this utility model proposes a medical airbag mattress to solve the above problems. Utility Model Content
[0008] The technical problem to be solved by this utility model is to provide a medical airbag mattress that reduces the feeling of unevenness, improves comfort, reduces airbag friction, and extends service life.
[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is: a medical airbag mattress, the innovation of which is: including a top layer of sponge, an airbag support layer and a bottom layer of sponge arranged from top to bottom;
[0010] The airbag support layer includes a sponge assembly, non-woven fabric, several airbags, and felt. The sponge assembly includes a central sponge and two side sponge bodies. Several airbag slots are formed along the length of the top surface of the central sponge. The two side sponge bodies are located on both sides of the width of the central sponge and cover both ends of each airbag slot. The non-woven fabric is flatly attached to the top surface of the central sponge and the surface of each airbag slot. Several airbags are sequentially arranged in the airbag slots along the length of the central sponge to form an airbag support area. At least one airbag is correspondingly arranged in each airbag slot. Each airbag is pressed against the top surface of the non-woven fabric at the corresponding airbag slot, and felt covers the top surface of each airbag.
[0011] Furthermore, the airbag support area is divided into a neck support area, a back support area, a waist support area, a hip support area, a thigh support area, and a calf support area along the length of the central sponge.
[0012] The bottom depth of the airbag grooves in the waist support area, thigh support area, and calf support area is the same, which is H. The bottom depth of the airbag grooves in the neck support area, back support area, and buttock support area is the same, which is h, and H < h.
[0013] Furthermore, the thigh support area has one airbag channel and two corresponding airbags.
[0014] Furthermore, the airbag support layer also includes air tubes connecting each airbag;
[0015] An air tube groove is opened on one side of the top surface of the middle sponge along the width direction. The air tube groove connects to the air bag groove. Non-woven fabric is flatly attached to the surface of the air tube groove. The air tube is connected to the bottom of the air bag. The air tube is set in the air tube groove and pressed against the top surface of the non-woven fabric at the air tube groove.
[0016] Furthermore, a gap is left between the adjacent airbag channels.
[0017] The advantages of this utility model are:
[0018] This invention features sponge layers on both the top and bottom sides of the airbag layer, with each airbag embedded within the airbag groove of the central sponge. Compared to simply laying sponge layers above or below the airbags, this design allows the mattress to achieve superior softness and comfort within a limited thickness range. The felt layer above the airbags keeps the mattress surface flat, further enhancing comfort. The non-woven fabric, flat against the surface of the central sponge and within the airbag grooves, strengthens the support for each airbag at the grooves, effectively preventing excessive compression of the central sponge by the airbags, thus avoiding the loss of their original firmness-adjusting effect. Furthermore, the non-woven fabric successfully isolates the airbags from the central sponge, preventing friction that could affect the mattress's lifespan.
[0019] This invention rationally designs the depth of the airbag grooves in each support area of the airbag support region. The airbag grooves in the waist, thigh, and calf support areas are shallower, while the corresponding airbag height is higher. In conjunction with the airbags in other support areas, the top surface of the airbag support region is more ergonomic, meeting the support needs of the human body and effectively improving comfort.
[0020] The present invention has one airbag channel in the thigh support area and two corresponding airbags, which enhances the support strength of the thigh support area.
[0021] This invention places the air tube below the airbag, which does not affect the comfort of the mattress. Furthermore, when the air tube is placed in the air tube groove, the non-woven fabric is used to enhance the structural strength of the air tube groove, preventing excessive compression of the middle sponge when the air tube is under pressure, thus avoiding affecting the service life of the middle sponge.
[0022] This invention improves the support strength of the gaps between airbags by leaving a gap between each pair of adjacent airbag slots, and also provides sufficient space for airbag deformation to prevent the airbags from overlapping under pressure. Attached Figure Description
[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Figure 2 This is a side view of the intermediate sponge body of this utility model. Detailed Implementation
[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0027] Example
[0028] This embodiment provides a medical airbag mattress, comprising, from top to bottom, a top layer of foam 1, an airbag support layer, and a bottom layer of foam 7, as shown below. Figure 1 As shown;
[0029] The airbag support layer includes a sponge assembly, non-woven fabric 4, ten airbags 3, felt 2, and air tubes 8 connecting each airbag 3.
[0030] The sponge assembly includes a central sponge 5 and two side sponge bodies 6. The top surface of the central sponge 5 has nine airbag channels 51 along its length. The top surface of the central sponge 5 has an air tube channel 52 along its width, which connects to each airbag channel 51. The two side sponge bodies 6 are located on both sides of the central sponge 5 in the width direction and cover both ends of each airbag channel 51. The central sponge 5 and the side sponge bodies 6 are both attached to the top surface of the sponge bottom layer 7 with hot melt adhesive. The non-woven fabric 4 is flatly attached to the top surface of the central sponge 5 and the surfaces of each airbag channel 51 and air tube channel 52 with hot melt adhesive.
[0031] Ten airbags 3 are sequentially arranged along the length of the central sponge body 5 within the airbag receiving groove 51 to form an airbag support area. Each airbag 3 is pressed against the top surface of the non-woven fabric at its corresponding airbag passage 51, and the sides of the airbags 3 are limited by the side wing sponge bodies 6. To ensure that the air tubes 8 do not affect the comfort of the mattress, the air tubes 8 are located below the airbags 3, within the air tube passage 52, and pressed against the top surface of the non-woven fabric at the air tube passage 52. The felt 2 is adhered to the top surface of each airbag using hot melt adhesive to keep the top surface of the mattress as flat as possible, and the top layer of sponge 1 is adhered to the top surface of the felt 2 using hot melt adhesive.
[0032] In this embodiment, as Figure 2 As shown, the airbag support area is divided into the following sections along the length of the central sponge 5: neck support area A, back support area B, waist support area C, hip support area D, thigh support area E, and calf support area F. There are three airbag channels at hip support area D, two airbag channels at back support area B, and one airbag channel at each of the other support areas. Two airbags are correspondingly installed in the airbag channel at thigh support area E to enhance the support strength of the thigh support area.
[0033] The bottom depth of the airbag channels in the lumbar support area C, thigh support area E, and calf support area F is the same, H. The bottom depth of the airbag channels in the neck support area A, back support area B, and hip support area D is the same, h, and H < h. In this embodiment, the bottom depth H of the airbag channels in the lumbar support area C, thigh support area E, and calf support area F is 30 mm, and the bottom depth h of the airbag channels in the neck support area A, back support area B, and hip support area D is 40 mm. The airbag channel depths in each support area are rationally designed. The airbag channels in the lumbar, thigh, and calf support areas are shallower, and the corresponding airbag heights are higher. Combined with the airbags in other support areas, this makes the top surface of the airbag support area more ergonomic, meeting the body's support needs and effectively improving comfort.
[0034] In this embodiment, a gap is left between adjacent airbag through slots 51, so that the top surface between two adjacent airbag through slots of the middle sponge remains flat. On the one hand, this improves the support strength at the gap between airbags, and on the other hand, it leaves enough space for airbag deformation to prevent the airbags from overlapping under pressure deformation.
[0035] The medical airbag mattress features foam layers on both the top and bottom of the airbag layer, with each airbag embedded within the airbag grooves of the central foam body. Compared to simply placing foam layers above or below the airbags, this design allows the mattress to achieve superior softness and comfort within a limited thickness range. A felt layer above the airbags keeps the mattress surface flat, further enhancing comfort. Non-woven fabric, applied flat to the surface of the central foam body and within the airbag grooves, strengthens the support for each airbag at the grooves, effectively preventing excessive compression of the central foam body by the airbags, thus avoiding the loss of their original firmness-adjusting effect. Furthermore, the non-woven fabric successfully isolates the airbags from the central foam body, preventing friction that could affect the mattress's lifespan.
[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
