The following disclosure provides many different embodiments, or examples, for implementing different features of the utility model. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the utility model.

Embodiments of the utility model are described in detail below with reference to the accompanying drawings.

In order to adapt to the monitoring of sleeping in different groups (such as adult and child, the size of the adult is obviously larger than that of the child), or in different demands (the importance degree of the monitoring of the patient is larger than that of the healthy person, namely important monitoring is needed), and meanwhile, the corresponding size can be adjusted according to the size of the bed, the inventor designs a sleeping monitoring device based on a flexible pressure sensor. The sleep monitoring device comprises a flexible carrier blanket 1, a flexible pressure sensor 2 and a controller (not shown in the figures). Wherein the flexible carrier blanket 1 is a fixed substrate of the flexible pressure sensor 2, which is flexible and may be folded or tiled arbitrarily to form a monitoring area with a preset area. For example, the original length and width dimensions of the flexible carrying blanket 1 are 200cm by 200cm, the length and width dimensions of the bed are 200cm by 200cm, and the flexible carrying blanket 1 can be tiled to form a monitoring area of 200cm by 200 cm. For another example, the original length-width dimension of the flexible carrier blanket 1 is 200cm×200cm, and the length-width dimension of the bed is 200cm×100cm, and then the flexible carrier blanket 1 may be folded along the length direction, so as to form a monitoring area of 200cm×100cm, as shown in fig. 2. For another example, the original length-width dimension of the flexible carrier blanket 1 is 200cm by 200cm, and in order to obtain a monitoring area of 100cm by 100cm, the flexible carrier blanket 1 may be folded along the length direction and then folded along the width direction. The folded flexible carrier blanket 1 will form an overlapping multi-layer structure that also combines the cushioning protection. Thus, flexible carrier blanket 1 may accommodate the size of multiple beds or sleep monitoring needs of different populations. The flexible pressure sensors 2 are arranged in the flexible bearing blanket 1 part in the monitoring area according to a preset arrangement rule and are detachably connected with the flexible bearing blanket 1 to form a pressure monitoring layer so as to test the pressure of a user lying on the flexible bearing blanket 1. For example, when the original length and width dimensions of the flexible carrying blanket 1 are 200cm by 200cm, and the monitoring area is 200cm by 200cm when the flexible carrying blanket 1 is completely tiled, a plurality of flexible pressure sensors 2 are arranged on the whole flexible carrying blanket 1 according to a preset arrangement rule. If the original length and width dimensions of the flexible carrier blanket 1 are 200cm by 200cm, a monitoring area of 200cm by 100cm is formed after folding (i.e. a two-layer structure is formed by folding), and a plurality of flexible pressure sensors 2 are arranged on the flexible carrier blanket 1 part of the monitoring area of 200cm by 100cm according to a preset arrangement rule (i.e. on any one layer of the two-layer structure). Therefore, the flexible pressure sensor 2 can be arranged according to different groups and different requirements, and the utilization rate of the flexible pressure sensor 2 is greatly improved. The controller is electrically connected to the plurality of flexible pressure sensors 2 to record and store the continuously sensed pressures of each flexible pressure sensor 2 over a continuous period of time. And in the later stage, the sleeping behavior of the user is analyzed by reading the pressure-time data in the controller, so that the sleeping situation of the user can be indirectly analyzed. The monitoring area of the sleep monitoring device based on the flexible pressure sensor is large, a user only needs to lie down naturally to sleep, other parts are not loaded, constraint is avoided, and experience is good.

Specifically, the flexible carrier blanket 1 is integrally formed by sewing dense woven fabrics or mesh fabrics made of cotton, chemical fiber and the like, and has a relatively thin thickness of about 1-2 mm, as shown in fig. 1. Flexible carrier blanket 1 includes a base layer 11 and a plurality of strap facings 12. The sum of the areas of the plurality of stripe cover layers 12 after being tiled is substantially identical to the area of the bottom layer 11. Each strip surface layer 12 is flatly paved on the bottom layer 11 one by one and then sewn in a crisscross manner, so that a plurality of storage bags 13 which are regularly arranged are formed on the bottom layer 11. Each pocket 13 has an opening. The flexible pressure sensor 2 can thus be inserted into the storage bag 13 through this opening and spread out, as shown in fig. 3. As shown in fig. 1, the bottom layer 11 and the tiled 5 strip surface layers 12 are sewn and combined to form 25 storage bags with the same area. The 25 storage bags 13 are arranged in a rectangular array mode, and 25 flexible pressure sensors 2 can be arranged in total.

In this embodiment, in order to facilitate the fixation of the flexible carrying blanket 1 and to indicate the size of the monitoring area formed after folding, a plurality of binding bands 14 are provided at the peripheral edge of the flexible carrying blanket 1. The binding by the binding 14 can enhance the fixing reliability of the flexible carrying blanket 1, and the approximate area of the monitoring area can be determined by the exposed binding 14.

In this embodiment, in order to prevent the flexible carrier blanket 1 from slipping during use, a plurality of silica gel point protrusions 15 are distributed on one side (i.e. the non-shielded side of the bottom layer 11 or the non-shielded side of the strip surface layer 12) or both sides of the flexible carrier blanket 1 in a dot shape. The silicone dot protrusions 15 can have the effect of increasing the friction between the flexible carrier blanket 1 and the mattress or the like, as well as between the interiors of the overlapping multilayer structures of the flexible carrier blanket 1.

A flexible pressure sensor 2, which employs a thin film pressure sensor. The flexible pressure sensors 2 are tiled in each storage bag 13 one by one, and the area of the flexible pressure sensors is slightly smaller than or equal to the area of the corresponding storage bag 13. When a user acts on the flexible pressure sensor 2 in the storage bag 13, a corresponding pressure is detected by the flexible pressure sensor 2.

In this embodiment, in order to reduce the shift in the position of the flexible pressure sensor 2 caused by the physical movement of the user during sleep, an auxiliary connection structure 21 is provided between the flexible pressure sensor 2 and the bottom layer 11. The auxiliary connection structure 21 comprises a hair surface layer 211 and a hook surface layer 212, and the hair surface layer 211 and the hook surface layer 212 form a glue-free magic tape structure. If the batt layer 211 is attached to the base layer 11, the hook layer 212 is attached to the flexible pressure sensor 2. Conversely, if the matte layer 211 is connected to the flexible pressure sensor 2, the hook layer 212 is connected to the base layer 11.

In this embodiment, in order to ensure the bonding strength, the area of the matted surface layer 211 or the matted surface layer 212 connected to the flexible pressure sensor 2 is the same as the area of the flexible pressure sensor 2, and is slightly smaller than or equal to the corresponding area of the matted surface layer 212 or the matted surface layer 211 connected to the bottom layer 11.

In this embodiment, in order to reduce the processing difficulty, the hook surface layer 212 or the rough surface layer 211 connected to the bottom layer 11 is directly sewn with the bottom layer 11 in a high-density crisscross manner by adopting a piece of hook surface layer 212 or rough surface layer 211 with the same area as the bottom layer 11. Thus, the flexible carrier blanket 1 is composed of the tape surface layer 12, the hook surface layer 212 or the rough surface layer 211, and the bottom layer 11 from top to bottom.

A controller is electrically connected to each flexible pressure sensor 22. In this embodiment, the controller is not designed with any improvement, and the technology known in the prior art is adopted.

When the sleep monitoring device based on the flexible pressure sensor in the embodiment is used, an adult is used for comprehensively detecting a monitored object, the length and width of the bed are considered to meet the requirement that the flexible carrying blanket 1 is completely paved, the flexible carrying blanket 1 is paved and fixed on the bed, and the whole flexible carrying blanket 1 is a larger monitoring area. The flexible pressure sensor 2 is horizontally laid in each storage bag 13, and unique numbers A1, A2, an are set one by one. Before the monitoring object lies down, the necessary quilt is put on, the flexible pressure sensor 2 is initially set to zero, and then the monitoring object normally lies down to sleep. The controller records pressure data of A1, A2, & gtA & gtan & lt, & gt, an after lying down from the post-monitor subject. After the monitoring object wakes up, the pressure-time data in the controller is read, and the sleeping situation of the monitoring object can be indirectly analyzed by analyzing the sleeping behavior of the monitoring object. For example, 22: 00-23: 00 All of A1 to An have pressure data reflecting that the monitored subject rolls over the opposite side, may not fall asleep or is treating light sleep. 23: 00-6 days: 00 A10 to A20 have relatively stable pressure data, reflecting that the subject has fallen asleep and is in deep sleep.
