Description

Technical Field

[0001] This application relates to the field of medical supplies technology, and more specifically, to a medical testing pad. Background Technology

[0002] In related technologies, sensors are typically integrated into the mat. After the patient lies on the mat, the sensors detect and acquire some indicators of the human body, such as using pressure sensors to detect the pressure of the human body on the mat, or using temperature sensors to detect the human body temperature, which are used as a basis for subsequent judgment of the patient's weight, body temperature, etc.

[0003] Some medical testing pads obtain human body parameters by distributing multiple sensors on the pad. For patients with different body types and conditions, some sensors are too far away from the patient to be of practical use, but the testing pad still needs to be cleaned and maintained, which is inconvenient to use.

[0067] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0068] like Figures 1 to 7 As shown, the medical testing pad 100 of this application is intended to solve the technical problems mentioned in the background section above.

[0069] like Figure 1 As shown, some embodiments of this application provide a medical testing pad 100, including: a sensor assembly 110 and a pad body unit 120.

[0070] The sensor component 110 is used to detect human body parameters, which serve as the basis for subsequent assessments of the user's physical indicators such as weight, body temperature, and water content. Figure 5 As shown, the pad unit 120 forms an inner cavity 121 for mounting the sensor assembly 110. The portion of the sensor assembly 110 located in the inner cavity 121 is isolated from the outside by the solidity of the pad unit 120 forming the inner cavity 121 to provide protection.

[0071] like Figure 3 As shown, the pad unit 120, as a basic unit equipped with the sensor assembly 110, has a first connecting portion 122 and a second connecting portion 123 on opposite sides. Specifically, the first connecting portion 122 of the pad unit 120 is adapted to form a detachable fixed connection with the second connecting portion 123 of another pad unit 120, so that at least two pad units 120 can be combined to form a pad array. That is, the pad units 120 can be combined to form a pad array with a certain surface area. During use, different sizes of pad arrays can be selected and combined according to the user's body size or the patient's different conditions for the patient to lie down or sit. After use, some pad units 120 can be removed for focused cleaning or maintenance, while the rest can be cleaned and disinfected routinely, making maintenance relatively convenient.

[0072] Using the above solution, the modularly installed pad units 120 can be integrated into a pad array, making it easy to perform local maintenance and local testing on patients with the medical testing pad 100.

[0073] like Figure 2 As shown, the size of the pad unit 120 is not limited, and at least some of the pad units 120 in the pad array can also be of different sizes to accommodate different body types of patients. Pad units 120 of different sizes can be used to form the pad array. Of course, the shape and size of each pad unit 120 can also be the same.

[0074] As a specific plan, the body indicators include: skin pressure index parameters; correspondingly, such as... Figure 5As shown, the sensor assembly 110 includes multiple pressure sensors 111. The pressure sensors 111 are used to acquire skin pressure index parameters. When in use, the patient lies on the pad unit 120. Due to the different weights of the patients, the pressure on the pressure sensors 111 also varies, and the patient's weight information can be obtained accordingly.

[0075] To facilitate the acquisition of skin pressure index parameters obtained from pressure sensor 111 at pad unit 120, pad unit 120 is provided with a connection terminal 124. The connection terminal 124 is electrically connected to pressure sensor 111.

[0076] Specifically, such as Figure 3 and Figure 5 As shown, the pad unit 120 is provided with multiple connection terminals 124, including a first terminal 124a and a second terminal 124b. The first terminal 124a and the second terminal 124b are respectively disposed on opposite sides of the pad unit 120. When two pad units 120 are combined, the first terminal 124a of one pad unit 120 is connected to the second terminal 124b of the other pad unit 120. This method allows the connection terminals 124 to transmit electrical signals. After the pad units 120 are combined into a pad array, they can be connected to external electronic devices such as computers through the connection terminals 124 of the outermost pad units 120 of the pad array. Thus, the electronic devices can receive skin pressure index parameters acquired by the pressure sensor 111. The first terminal 124a and the second terminal 124b are conductors. The specific connection method between them can be achieved by magnetic attraction, nesting, plugging, etc., to achieve mutual contact and thus transmit electrical signals.

[0077] More specifically, such as Figure 4 As shown, at least two first connecting portions 122 are spaced apart on one side of the pad unit 120, and a first terminal 124a is located between two adjacent first connecting portions 122. Similarly, multiple second connecting portions 123 can be spaced apart on one side of the pad unit 120, and a second terminal 124b is located between two adjacent second connecting portions 123. This method, on the one hand, enhances the connection strength between the pad units 120 by increasing the number of connecting portions between adjacent pad units 120, and on the other hand, by placing the first connecting portions 122 and the second connecting portions 123 around the connecting terminals 124, the connection between the connecting terminals 124 is less likely to loosen, ensuring the stability of electrical signal transmission.

[0078] In one embodiment, such as Figure 6As shown, the pressure sensor 111 includes a first electrode 111a, a pressure-sensitive unit 111b, and a second electrode 111c stacked together. The pressure-sensitive unit 111b is electrically connected to the first electrode 111a and the second electrode 111c. The first electrode 111a and the second electrode 111c can be made of materials such as copper or conductive cloth. The pressure-sensitive unit 111b is made of a pressure-sensitive material. When the pressure-sensitive unit 111b is subjected to pressure, its resistance changes. After the pressure-sensitive unit 111b is connected to the circuit through the first electrode 111a and the second electrode 111c, the pressure on the corresponding area of ​​the medical detection pad 100 can be measured by the change in the resistance of the pressure-sensitive unit 111b. In this way, the weight of the patient lying on the pad unit 120 can be calculated.

[0079] In one embodiment, such as Figure 5 and Figure 6 As shown, the medical testing pad 100 also includes a positioning member 130. The positioning member 130 is installed in the inner cavity 121 and has a first positioning groove 131 and a second positioning groove 132. At least a portion of the first electrode 111a is embedded in the first positioning groove 131, and at least a portion of the second electrode 111c is embedded in the second positioning groove 132. This arrangement utilizes the first positioning groove 131 and the second positioning groove 132 to position and install the first electrode 111a and the second electrode 111c, reducing the shaking of the first electrode 111a and the second electrode 111c relative to the medical testing pad 100 body during movement and use, thus reducing the possibility of damage to the first electrode 111a and the second electrode 111c.

[0080] Specifically, such as Figure 5 As shown, the medical testing pad 100 also includes a circuit board 140. The circuit board 140 is electrically connected to the first electrode 111a and the second electrode 111c, respectively, to receive skin pressure index parameters acquired by the pressure sensor 111. The circuit board 140 can be, for example, a flexible circuit board 140, which can be bent when under pressure, making it more suitable for use in the pad unit 120. Circuit board 140 is electrically connected to the first terminal 124a and the second terminal 124b to realize the electrical connection between pressure sensor 111, the first terminal 124a, and the second terminal 124b. Specifically, circuit board 140 is used to realize the electrical connection between the first terminal 124a and the second terminal 124b and the pressure sensor 111, so that the pressure sensor 111, which is composed of the first electrode 111a, the pressure-sensitive unit 111b, and the second electrode 111c, can be connected to the first terminal 124a and the second terminal 124b through circuit board 140. It can be understood that the first terminal 124a and the second terminal 124b can be connected to the positive and negative terminals of the external power supply, respectively. After the first terminal 124a and the second terminal 124b are connected to the power supply, they can supply power to the pressure sensor 111.

[0081] Multiple pressure sensors 111 can be installed in the inner cavity 121 of the pad unit 120. The pressure-sensitive units 111b of each pressure sensor 111 are distributed at intervals, for example, in a matrix distribution. This allows the pressure on multiple parts of the pad unit 120 to be obtained through more pressure sensors 111. Subsequently, the average pressure on the pad unit 120 can be determined by taking the average value as the basic parameter for calculating the patient's weight, which can reduce measurement errors.

[0082] As a specific solution, such as Figure 5 As shown, the medical testing pad 100 also includes: a first connector 150 and a second connector 160.

[0083] The plurality of first connectors 150 are electrically connected to the circuit board 140. The plurality of second connectors 160 are electrically connected to the first terminal 124a or the second terminal 124b.

[0084] In this design, one of the first connector 150 and the second connector 160 serves as an interface for electrical connection, and the other serves as a connector for electrical connection. Multiple first connectors 150 are connected one-to-one to multiple second connectors 160, enabling electrical connection between the circuit board 140 and the first terminal 124a or the second terminal 124b. The first connectors 150 and their corresponding second connectors 160 form a detachable fixed connection, such as a plug-in or threaded connection. Through the cooperation of the first connectors 150 and the second connectors 160, the surface of the pad unit 120 can be connected to the internal circuit board 140. Furthermore, when it is necessary to repair or replace a damaged sensor assembly 110, the first connectors 150 and the second connectors 160 can be separated, facilitating the subsequent removal of the circuit board 140 and the sensor assembly 110 from the pad unit 120.

[0085] As a specific solution, such as Figure 3 As shown, the pad unit 120 includes a body portion 125 and a side skirt portion 126. The body portion 125 forms the aforementioned inner cavity 121, and the periphery of the body portion 125 has an opening communicating with the inner cavity 121. The circuit board 140, sensor assembly 110, etc. can be inserted into the inner cavity 121 through the opening, or the inner cavity 121 can be removed from the opening, which facilitates the repair and replacement of the sensor assembly 110 and the circuit board 140.

[0086] The side skirt 126 protrudes from the periphery of the main body 125. The first terminal 124a and the second terminal 124b can be disposed at the side skirt 126, so that the first terminal 124a and the second terminal 124b are located outside the inner cavity 121, which facilitates connection with another pad unit 120 or an external electronic device. When the first terminals 124a and the second terminals 124b of two adjacent pad units 120 are combined, the side skirt 126 that is disposed of to cover the first terminals 124a and the second terminals 124b can prevent the patient's body from contacting the first terminals 124a and the second terminals 124b during use, thus ensuring electrical safety.

[0087] Among them, such as Figure 4 As shown, one of the outer periphery of the main body 125 and the side skirt 126 is provided with a protruding strip 126a, and the other of the outer periphery of the main body 125 and the side skirt 126 is provided with a fitting groove 125a. The protruding strip 126a and the fitting groove 125a are located outside the opening. The protruding strip 126a is fitted into the fitting groove 125a to close the opening. The fitting of the protruding strip 126a and the fitting groove 125a can close the opening and ensure the sealing of the inner cavity 121. Alternatively, the protruding strip 126a and the fitting groove 125a can be separated to allow the opening to be opened, which facilitates the maintenance and replacement of the sensor assembly 110 and the circuit board 140.

[0088] In one embodiment, the body parameters also include skin temperature parameters, meaning that the sensor assembly 110 can also be used to detect the patient's body temperature, thus enriching the functionality of the medical detection pad 100.

[0089] Specifically, such as Figure 7 As shown, the sensor assembly 110 also includes a temperature sensor 112.

[0090] Temperature sensor 112 is used to acquire skin temperature parameters, and is connected to circuit board 140 so that the electrical signal containing the patient's body temperature information acquired by temperature sensor 112 can be transmitted through circuit board 140 to the first terminal 124a or the second terminal 124b, facilitating the acquisition or calculation of the patient's body temperature by external devices. Temperature sensor 112 can specifically be a thermistor, infrared temperature sensor, etc.

[0091] The pad unit 120 has a perforation 127 that communicates with the inner cavity 121. The temperature sensor 112 is at least partially embedded in the perforation 127. When using the medical test pad, this setting allows the temperature sensor 112 to be closer to the patient's body surface, thereby ensuring the accuracy of body temperature detection.

[0092] In one embodiment, the body index parameters also include: body surface impedance index parameters, that is, the medical test pad can also be used to detect the patient's bioimpedance, and the water content of the patient's body surface can be calculated accordingly.

[0093] As a specific solution, such as Figure 7 As shown, the sensor assembly 110 also includes a reference electrode 113 and test electrodes 114. The reference electrode 113 and multiple test electrodes 114 are respectively connected to the circuit board 140, and the multiple test electrodes 114 are disposed around the reference electrode 113. The pad unit 120 should have corresponding openings for the reference electrode 113 and test electrodes 114 to protrude from the inner cavity 121. When the reference electrode 113 and test electrodes 114 are energized, the patient's body surface contacts the reference electrode 113 and test electrodes 114. The body impedance of the patient's body surface can be obtained by detecting the current between the reference electrode 113 and test electrodes 114. Because the bioimpedance changes accordingly with different water content in the human body, the water content of a portion of the patient's body surface can be estimated. It is understood that a current sensor or similar device needs to be installed on the circuit containing the reference electrode 113 and test electrodes 114 to detect changes in current. The current sensor can be integrated into the inner cavity 121.

[0094] In a more specific configuration, the distance between multiple test electrodes 113 and reference electrodes 114 is equal, meaning the multiple test electrodes 114 are arranged in a circle, with the reference electrode 113 located at the center. This setup allows for the separate measurement of bioimpedance of the patient's body surface regions located between the reference electrode 113 and each test electrode 114.

[0095] In one embodiment, such as Figure 7 As shown, there can be multiple circuit boards 140, such as a first circuit board 141 and a second circuit board 142 arranged in layers. The pressure sensor 111 is connected to the first circuit board 141, and the temperature sensor 112, the detection electrode 114 and the reference electrode 113 are connected to the second circuit board 142. Accordingly, the pressure sensor 111 can be arranged on one layer, while the temperature sensor 112, the detection electrode 114 and the reference electrode 113 can be arranged on another layer. The layered design allows the pad unit 120 to integrate multiple sensors in a small surface area.

[0096] As an example of the specific connection method between the pad units 120, such as Figure 4As shown, the first connecting part 122 is configured as a hook and loop fastener 122a, and the second connecting part 123 is configured as a hook and loop fastener fiber 123a, meaning that the pad units 120 are connected by hook and loop fasteners. Specifically, for the pad array, the hook and loop fastener 122a of the pad unit 120 is attached to the hook and loop fastener fiber 123a of the adjacent pad unit 120. This connection method ensures stable connection between adjacent pad units 120. Considering that the pad unit 120 needs to contact the patient's skin, it needs to be made of soft materials such as leather or silicone. The connection method of attaching the hook and loop fastener 122a to the hook and loop fastener fiber 123a can separate the first connecting part 122, the second connecting part 123, and the patient's skin, allowing the surface of the pad unit 120 that contacts the patient's skin to be set to a relatively flat surface, ensuring a better user experience and preventing discomfort caused by direct contact with the first connecting part 122 and the second connecting part 123.

[0097] In actual use, the first connecting part 122 and the second connecting part 123 can also be configured as a zipper, strap, or other specific connection form, and this application does not impose any specific restrictions on this.
