Description

Technical Field

[0001] This utility model belongs to the field of intelligent mattress technology, and in particular relates to a flexible fiber pressure anti-bedsore sensor mattress. Background Technology

[0002] With socio-economic development and the accelerated pace of life, people are paying increasing attention to their health. Sleep health is a crucial component of overall well-being, yet most people are unaware of its importance. We spend one-third of our lives sleeping, and good sleep is vital for restoring physical strength, enhancing cognitive function, and ensuring overall sleep health. Therefore, how to objectively present sleep patterns through monitoring devices, allowing people to clearly understand their sleep status, is receiving increasing attention from researchers.

[0003] Currently, most monitoring methods used by various institutions are cameras, infrared monitoring, thin-film sensors, or smartwatches. However, these methods involve personal facial information, raising concerns about data leakage. Furthermore, they suffer from limited detection distance, poor breathability, and a feeling of constraint.

[0004] In view of the above problems, our company has developed a flexible fiber pressure-resistant mattress to prevent bedsores. Utility Model Content

[0008] In some exemplary embodiments, the first encapsulation layer and the second encapsulation layer are made of fabric.

[0009] In some exemplary embodiments, the first data acquisition layer consists of multiple longitudinal transmission lines arranged vertically on the pressure value acquisition layer; the second data acquisition layer consists of multiple transverse transmission lines arranged horizontally below the pressure value acquisition layer; all the longitudinal transmission lines and all the transverse transmission lines are electrically connected to the circuit board module; all the longitudinal transmission lines and all the transverse transmission lines are arranged to cross each other, and the crossing position is a pressure sensing point.

[0010] In some exemplary embodiments, the first data acquisition layer consists of multiple horizontal transmission lines arranged horizontally below the pressure value acquisition layer; the second data acquisition layer consists of multiple vertical transmission lines arranged vertically above the pressure value acquisition layer; all the vertical transmission lines and all the horizontal transmission lines are electrically connected to the circuit board module; all the vertical transmission lines and all the horizontal transmission lines are arranged to cross each other, and the crossing point is a pressure sensing point.

[0011] In some exemplary embodiments, the pressure data acquisition layer is a pressure data acquisition layer made of multiple flexible fiber pressure sensors processed according to textile technology.

[0012] Compared with existing technologies, the beneficial effects of this patented technology, which adopts the above technical solution, are as follows:

[0013] The pressure data acquisition layer of this invention is made by fabricating multiple flexible fiber pressure sensors into a fabric shape according to textile technology. It works in conjunction with the cross-arranged transmission lines in the first and second data acquisition layers to collect changes in human body pressure and specific pressure values. The data is finally transmitted to the circuit board for data acquisition and processing.

[0014] The product of this utility model is manufactured using textile technology.

[0021] Preferred embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0022] Example

[0023] like Figure 1-3 As shown, a flexible fiber pressure anti-bedsore sensor mattress includes, from top to bottom: a first encapsulation layer 1; a first data acquisition layer 2; a pressure value acquisition layer 3; a second data acquisition layer 4; a second encapsulation layer 5; and a circuit board module 6.

[0024] The first encapsulation layer 1 and the second encapsulation layer 5 are made of fabric. There are various options for the fabric; it can be a fabric with one or more functions such as antistatic, water-repellent, oil-repellent, fold-resistant, breathable, and antibacterial. The choice of fabric is modified according to market and customer needs during actual production. In addition, other materials such as films and leather that can achieve the functions of fabric are also within the scope of protection of this utility model.

[0025] The first data acquisition layer 2 and the second data acquisition layer 4 are electrically connected respectively to acquire data collected by all the sensors for data processing.

[0026] The first data acquisition layer 2 and the second data acquisition layer 4 are respectively located on the upper and lower sides of the pressure value acquisition layer 3, and there are two implementation methods.

[0027] The first implementation is as follows: The first data acquisition layer 2 consists of multiple vertical transmission lines arranged vertically on the pressure value acquisition layer 3. The second data acquisition layer 4 consists of multiple horizontal transmission lines arranged horizontally below the pressure value acquisition layer 3. All the vertical and horizontal transmission lines are electrically connected to the circuit board module 6. All the vertical and horizontal transmission lines are arranged to cross each other, and the crossing points are pressure sensing points.

[0028] The second implementation is as follows: The first data acquisition layer 2 consists of multiple horizontal transmission lines arranged horizontally below the pressure value acquisition layer 3. The second data acquisition layer 4 consists of multiple vertical transmission lines arranged vertically on the pressure value acquisition layer 3. All vertical and horizontal transmission lines are electrically connected to the circuit board module 6. All vertical and horizontal transmission lines are arranged intersectingly, and the intersection points are pressure sensing points.

[0029] The pressure data acquisition layer 3 is a pressure data acquisition layer made of multiple flexible fiber pressure sensors processed according to textile technology.

[0030] Circuit board module 6 acquires data collected by all the sensors, processes the data, and transmits the data to the backend server.

[0031] During operation, the flexible fiber pressure sensor changes its resistance due to pressure applied from both the top and bottom surfaces, thus affecting the output current. The current is inversely proportional to the applied pressure; the higher the pressure, the lower the current. Taking a configuration of 32 transverse and 32 longitudinal transmission lines as an example, this results in 1024 relatively independent pressure sensing points. When a person lies on the mattress, the system detects the current changes at these corresponding points based on this principle, monitoring the pressure values ​​of various parts of the body below the head in real time. Based on these pressure changes, the system identifies bodily characteristics such as whether the user is on or off the bed, their sleeping posture, body movement, and breathing, providing reliable feedback on changes in body pressure without the user even noticing.

[0032] The product of this utility model is manufactured using textile technology. It can be laid on bed sheets for testing, and can even be laid on soft mattresses with a thickness of less than 3cm, still allowing for the monitoring of pressure changes. Furthermore, this utility model product has advantages such as breathability, foldability, and reusability after washing, and is also low in cost, giving it a significant advantage over other products.

[0033] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention herein. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art that are not covered by the invention. The specification and examples are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the appended claims.

[0034] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
