Description

Technical Field

[0001] This utility model relates to the field of body temperature measurement technology, and in particular to a temperature display anti-fall-off body temperature patch. Background Technology

[0002] In recent years, disposable temperature patches have been introduced into clinical practice to achieve continuous monitoring. Compared with traditional intermittent temperature measurement (such as axillary thermometers and forehead thermometers), disposable temperature patches can provide a continuous and real-time flow of body temperature data, which helps medical staff to detect abnormal temperature trends earlier (such as postoperative fever or drug reaction). They are especially suitable for critically ill patients, newborns and scenarios that require close temperature monitoring.

[0003] However, traditional body temperature patches rely on pressure-sensitive adhesive (PSA) layers for fixation, which has significant drawbacks: when the skin sweats or joints move, the adhesive layer's adhesion decreases, easily causing the edges to lift and creating gaps between the temperature-sensing element and the skin. This makes the measured temperature susceptible to interference from ambient airflow, leading to inaccuracies. Furthermore, if the rigid temperature-sensing module does not match the skin's curvature, it can create localized pressure points, reducing comfort and increasing the risk of adhesive detachment. In addition, disposable patches, for hygiene and safety reasons, cannot be repeatedly repositioned and adjusted, resulting in loss of monitoring function if poorly applied initially (especially in areas with many skin folds, such as the armpit and neck). Existing methods to improve stability by thickening the adhesive layer or increasing the area often lead to reduced breathability and skin irritation, making them unsuitable for long-term monitoring.

[0004] CN215952817U discloses a disposable passive body temperature patch based on RFID technology. The body temperature patch forms a ring-shaped fixing structure by combining an adhesive layer with an elastic nylon fixing strap and a magic mother-daughter patch, which can reduce the risk of falling off in sports or humid environments.

[0005] However, this patented temperature patch has a significant drawback: when attaching the patch to the user's test site, the device relies solely on the adhesive tape to hold it in place, neglecting the fact that the annular tape creates a cavity between the skin and the temperature sensor, failing to expel the air from this cavity. This trapped air layer reduces the actual contact area between the tape and the skin, leading to uneven adhesion. During limb movement or when the skin sweats, the edges are prone to stress concentration and peeling off first. This gradual delamination causes the entire temperature patch to loosen. Furthermore, the rigid temperature patch body has poor adaptability to skin curvature, easily causing the edges to lift up in uneven areas such as joints or armpits due to insufficient adhesion, making it difficult to meet the continuous monitoring needs of postoperative patients.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0007] To address the shortcomings of existing technologies, this application proposes a body temperature patch, a body temperature patch that displays temperature, and in particular a body temperature patch that displays temperature in real time and prevents it from falling off, aiming to solve one or more technical problems in the prior art.

[0008] This utility model relates to a temperature-displaying, non-detachable body temperature patch, comprising: an adhesive part that adheres to the skin surface, the surface of which is distributed with a plurality of breathable grooves; a temperature measuring part that is detachably installed on the adhesive part, the temperature measuring part having a temperature measuring head, and vents around the temperature measuring head corresponding to the positions of the breathable grooves; when the temperature measuring part is installed on the adhesive part, the temperature measuring head extends into the temperature measuring cavity formed between the adhesive part and the skin surface, and each vent is connected to the corresponding breathable groove to form an exhaust channel; when the temperature measuring part is rotated at a set angle relative to the adhesive part, the vents and the breathable grooves are misaligned and blocked, thereby sealing the temperature measuring cavity.

[0009] When the temperature measuring unit is installed onto the adhesive part, the temperature probe enters the temperature measuring chamber, compressing the existing air inside and forcing some of the gas to escape through the ventilation channel (vent groove and vent port). Subsequently, rotating the temperature measuring unit to a set angle causes the vent port and vent groove to completely seal the ventilation channel. At this point, the increased air volume inside the temperature measuring chamber prevents backflow, creating a localized negative pressure. This negative pressure is evenly transmitted to the skin contact surface through the flexible substrate of the adhesive part, maintaining a close fit between the device and the skin while significantly enhancing overall adhesion. Furthermore, the misalignment formed by the vent port and vent groove quickly seals the temperature measuring chamber, effectively isolating the temperature probe from external temperature fluctuations and ensuring the accuracy of body temperature data.

[0010] According to a preferred embodiment, the adhesive part and the temperature measuring part are detachably connected by a fixing assembly. The fixing assembly includes several positioning holes distributed on the upper surface of the adhesive part, each positioning hole connected to a rotating groove. The lower surface of the temperature measuring part is provided with several connectors corresponding to the positions of the positioning holes. When a connector is inserted into a corresponding positioning hole, the connector can move along the rotating groove, causing the temperature measuring part to rotate relative to the adhesive part in a predetermined direction. When the connector is inserted into the positioning hole, its path constraint with the rotating groove forms a physical guide, ensuring that the temperature measuring part can only rotate in the preset direction, avoiding sealing failure or structural misalignment problems caused by deflection angle deviation.

[0011] According to a preferred embodiment, the inner wall of the end of the rotating groove is provided with a recess, and the side wall of the connector is provided with a protrusion corresponding to the recess. When the connector rotates to the end of the rotating groove, the protrusion engages with the corresponding recess to form a circumferential limit, keeping the temperature measuring unit at its current rotation angle. When the connector rotates to the end of the rotating groove, the mechanical resistance generated by the protrusion engaging with the recess provides clear feedback, indicating to the operator through touch or a slight sound that the rotation has been completed, ensuring that the misalignment and blockage between the vent and the vent groove achieve a preset sealing state. In addition, the embedded engagement of the protrusion and the recess creates circumferential contact constraint, effectively resisting accidental rotation of the temperature measuring unit caused by external vibration or skin movement, and preventing negative pressure leakage or accidental connection of the exhaust channel due to angular deviation.

[0012] According to a preferred embodiment, the connector includes a vertically arranged rod and a spherical head at the end of the rod, the diameter of the spherical head being larger than the diameter of the rod to form a mushroom-shaped snap-fit ​​structure. The inner wall of the rotating groove is provided with a guide slope extending from the inner edge of the positioning hole into the rotating groove. When the connector is inserted into the positioning hole, its surface contacts the guide slope and slides along it, thus automatically sliding into the rotating groove under the guidance of the guide slope. When the connector is inserted into the positioning hole, the inclined contact surface between its surface and the guide slope generates a lateral guiding force, forcing the connector to adaptively adjust the insertion angle along the slope direction, eliminating the problem of axial misalignment between the connector and the rotating groove caused by manual operation deviations. The continuous transition structure of the guide slope extending from the inner edge of the positioning hole to the rotating groove allows the connector to automatically calibrate its path by sliding along the slope even if it is not perfectly aligned, reducing the dependence of assembly operations on precision.

[0013] According to a preferred embodiment, the concave hole has an annular elastic layer on its wall, and the protrusion is a spherical boss adapted to the elastic layer. The thickness of the elastic layer gradually decreases from the opening end of the concave hole to the bottom, forming a self-locking engagement between the concave hole and the protrusion. When the protrusion is inserted into the concave hole, the thickness of the elastic layer exhibits an inverted conical cross-sectional characteristic, thicker at the opening and thinner at the bottom. This causes significant radial compression deformation of the elastic layer in the opening region due to its greater thickness during axial pressing, while the deformation gradually decreases in the bottom region. The wedge-tightening effect generated when the protrusion and concave hole engage effectively prevents the protrusion from disengaging from the concave hole.

[0014] According to a preferred embodiment, the upper surface of the adhesive part is provided with a receiving hole that fits closely to the temperature measuring head. The depth of the receiving hole is less than the height of the temperature measuring head, so that when the temperature measuring head passes through the receiving hole into the temperature measuring cavity, its bottom surface protrudes from the bottom surface of the adhesive part and forms surface contact with the skin. When the temperature measuring head passes through the receiving hole, its bottom surface protrudes from the bottom surface of the adhesive part due to the insufficient depth of the receiving hole, directly forming a stable surface contact with the skin. The micro-pressure effect generated by the protruding structure on the skin contact surface causes the temperature measuring head to slightly embed into the superficial layer of the epidermis, increasing the effective contact area and reducing measurement interference caused by local sweat or hair.

[0015] According to a preferred embodiment, the adhesive part includes a base, a portion of which is raised to form a temperature measuring cavity. A receiving hole and a venting groove are formed at the top of the raised area of ​​the base. A fixing component is disposed on the surface of a non-raised area of ​​the base surrounding the raised area. The temperature measuring cavity formed by the raised base concentrates the temperature measuring head and its surrounding venting structure in a locally elevated area, spatially separating the heat conduction path inside the temperature measuring cavity from the heat exchange interface with the external environment, effectively reducing interference from external structures such as the fixing component on the temperature field of the temperature measuring cavity. The receiving hole and venting groove, located at the top of the raised area, allow for the full expulsion of air from the temperature measuring cavity when the temperature measuring part and the adhesive part are engaged, creating a negative pressure effect.

[0016] According to a preferred embodiment, the bottom surface of the adhesive part is provided with several elongated limiting grooves, into which the adhesive tape can be detachably embedded. After embedding, the adhesive surface of the bottom of the adhesive tape is coplanar with the bottom surface of the adhesive part. The geometric constraint of the elongated limiting grooves effectively restricts the lateral displacement of the adhesive tape under shear force. At the same time, its open groove structure allows for quick replacement or local adjustment of the tape length to adapt to the fitting needs of different skin curvatures. The coplanarity of the adhesive surface of the tape and the bottom surface of the adhesive part after embedding ensures uniform pressure distribution when the device comes into contact with the skin, avoiding edge lifting or stress concentration caused by local height differences, thus improving adhesion stability and reducing the pressure sensation during long-term wear.

[0017] According to a preferred embodiment, the top of the temperature measuring unit is provided with a cover plate for mounting a temperature measuring head. A display screen is integrated on the surface of the cover plate and is electrically connected to the temperature measuring head to display the real-time body temperature measured by the head. By integrating the display screen onto the surface of the cover plate and forming an electrical connection with the temperature measuring head, real-time visual feedback of body temperature data is achieved. The cover plate, as an integrated carrier, significantly optimizes the structural compactness of the device while ensuring the stability of the temperature measuring head installation, avoiding the space redundancy problems caused by traditional external display modules.

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] This embodiment relates to a temperature-displaying, non-detachable body temperature patch, such as... Figure 1 , Figure 2 As shown, it mainly consists of two parts: a temperature measuring unit 100 and an adhesive unit 200, which can be detachably connected by plugging and rotating. The adhesive unit 200 is a flat structure that comes into direct contact with the skin. Its main body is a base 210 made of flexible material. The bottom surface of the base 210 can be fitted with a medical-grade adhesive tape 240 to adhere to the temperature measurement point on the user's skin (e.g., underarm, chest, forehead, etc.). The temperature measuring unit 100 includes a circular cover plate 110. A columnar temperature measuring head 120 is vertically mounted at the center of the lower surface of the cover plate 110. The bottom of the temperature measuring head 120 is the temperature measuring end face that contacts the skin, and the top is integrated with a temperature sensor within the cover plate 110.

[0028] like Figure 1 , Figure 2As shown, the central area of ​​the base 210 of the adhesive part 200 is raised, thus forming a temperature measuring cavity 230 with the skin surface. A receiving hole 211 for the temperature measuring head 120 to enter the temperature measuring cavity 230 is provided at the center of the top of the base 210. Multiple venting grooves 212 are evenly distributed around the receiving hole 211 outwards, and the spacing between each venting groove 212 is preferably equal. The lower surface of the cover plate 110 is also provided with annularly distributed vents 112. The number of vents 112 is the same as the number of venting grooves 212 in the adhesive part 200, and their positions correspond. Each vent 112 is a long, arc-shaped through hole penetrating the upper and lower surfaces of the cover plate 110. Preferably, the upper surface edge of the cover plate 110 is also provided with two symmetrically distributed recesses 113. The inner wall of the recesses 113 is processed with dense transverse anti-slip textures, the depth of which is moderate to facilitate finger gripping and application of force.

[0029] Based on the elastic properties of skin, and since the base 210 can also be made of a flexible material with elastic deformation capabilities, such as silicone rubber or synthetic rubber, the volume of the temperature measuring cavity 230 can change when the temperature measuring part 100 and the adhesive part 200 are rotated together. This change generates negative pressure, thereby enhancing the adhesion of the body temperature patch. First, when the temperature measuring part 100 and the adhesive part 200 are inserted and fitted, the operator applies pressure to the cover plate 110 covering the base 210. This pressure causes the top of the temperature measuring head 120 and the flexible raised area of ​​the base 210 to move closer to the skin, causing the volume of the temperature measuring cavity 230 to shrink. At this time, some of the air inside the temperature measuring cavity 230 is discharged through the channel formed by the vent groove 212 and the vent 112. Subsequently, during the rotation and fixing process of the temperature measuring part 100 and the adhesive part 200, the vent 112 of the cover plate 110 and the vent groove 212 of the base 210 are completely misaligned, blocking the gas exchange inside and outside the temperature measuring cavity 230. After the operator releases the pressure on the cover plate 110, the skin's elasticity pushes the temperature measuring head 120 and the cover plate 110 away from the skin, thereby causing the flexible raised area of ​​the base 210 to return to a flat state, and the volume of the temperature measuring cavity 230 expands accordingly. The expansion of the volume creates negative pressure inside the temperature measuring cavity 230, thereby enhancing the adhesion of the body temperature patch and improving its wearing stability.

[0030] like Figure 1 As shown, the temperature measuring unit 100 includes a cover plate 110 disposed on the upper surface of the base 210. Multiple fixing components 220 are distributed in the portion of the base 210 corresponding to the outer peripheral area of ​​the cover plate 110. Each fixing component 220 includes a positioning hole 221 and a rotating groove 222. The positioning hole 221 is a circular through hole located on the non-protruding surface of the receiving hole 211 of the base 210. The rotating groove 222 is an arc-shaped groove, with one end communicating with the positioning hole 221 and the other end extending clockwise (or counterclockwise) to form an arc trajectory.

[0031] like Figure 1 , Figure 2As shown, the lower surface of the cover plate 110 near the edge is provided with multiple plug-in pieces 111. The positions of the plug-in pieces 111 correspond one-to-one with the positioning holes 221 of the base 210 of the adhesive part 200. Each plug-in piece 111 includes a vertical rod and a spherical head at the end of the rod. The diameter of the spherical head is larger than the diameter of the rod to form a mushroom-shaped snap-fit ​​structure. Figure 3 As shown, the side wall of the connector 111 is machined with a spherical protrusion 111.1. The position of the protrusion 111.1 corresponds to the concave hole 223 at the end of the rotating groove 222 of the adhesive part 200. Its diameter is slightly smaller than the opening size of the concave hole 223, so that the two can be detachably fixedly connected by aligning and engaging the protrusion 111.1 on the cover plate 110 with the concave hole 223 of the base 210.

[0032] like Figure 4 As shown, the inner wall of the rotating groove 222 is provided with a guide slope, which slopes from the inner edge of the positioning hole 221 toward the end of the rotating groove 222, thereby forming a transition surface from shallow to deep. Those skilled in the art can optimize the parameters of the guide slope using conventional engineering methods to ensure reliable sliding. The slope angle is typically selected in the range of 20° to 30°. In addition, a radius of R0.2 to R0.5 can be provided at the end of the slope to reduce the risk of jamming when the connector 111 is inserted.

[0033] The inner wall of the end of the rotating groove 222 is machined with a recess 223, the opening of which faces the center of the positioning hole 221. An annular elastic layer is provided at the edge of the hole opening. The elastic layer is made of silicone or another material with a Shore hardness range similar to silicone, and its thickness gradually decreases from the opening end of the recess 223 to the bottom, forming a tapered constriction structure. Through the cooperation between the protrusion 111.1 and the recess 223, the base 210 and the cover plate 110 can be detachably connected by relative rotation along the arc trajectory of the rotating groove 222. To ensure a relatively stable fit between the base 210 and the cover plate 110, the diameter of the protrusion 111.1 and the opening of the recess 223 have an interference fit of, for example, -0.3 mm to -0.1 mm.

[0034] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6During installation, the operator first removes the protective film from the bottom surface of the base 210 of the adhesive part 200 and attaches the base 210 to the skin surface. At this time, a sealed temperature measuring cavity 230 is formed between the bottom surface of the annular protrusion 111.1 structure and the skin. Next, the connector 111 below the cover plate 110 of the temperature measuring part 100 is aligned with the positioning hole 221 of the base 210 of the adhesive part 200 and pressed vertically down. After the spherical head of the connector 111 contacts the guide slope in the rotating groove 222, it moves in a direction and slides into the starting end of the rotating groove 222 along the slope. After the connection is completed, the operator grasps the notch 113 and rotates the cover plate 110 clockwise. The connector 111 moves along the arc trajectory of the rotating groove 222, causing the entire temperature measuring part 100 to rotate relative to the adhesive part 200. When rotated to the set angle, the protrusion 111.1 on the side wall of the connector 111 aligns with the recess 223 at the end of the rotating groove 222. Under the action of elastic restoring force, the protrusion 111.1 is embedded in the recess 223. At this time, the elastic layer inside the recess 223 is compressed and deformed, and a self-locking effect is generated through the conical closing structure, so that the cover plate 110 remains at a fixed angle and cannot rotate on its own. During this rotation, the end plane of the temperature measuring head 120, which passes through the receiving hole 211 and enters the temperature measuring chamber 230, always maintains surface contact with the skin surface. At the same time, the overlapping area of ​​the vent 112 and the vent groove 212 gradually decreases, and eventually completely misaligns to form a shield, thereby sealing the communication channel between the temperature measuring chamber 230 and the outside world.

[0035] Those skilled in the art can determine the preferred rotation angle based on the number and distribution of the vent 112 and the vent groove 212 to improve the sealing effect of the temperature measuring chamber 230. For example, as... Figure 5 As shown, when there are three vents 112 and three vent grooves 212, and they are evenly distributed circumferentially on the cover plate 110 and the base 210 respectively, and the circumferential interval between adjacent vents 112 or vent grooves 212 is 120°, the rotation angle can be set to 60°. After rotation, the vent 112 will precisely move to the non-grooved area between two adjacent vent grooves 212, forming a staggered obstruction. Furthermore, although not shown in the figure, those skilled in the art will readily understand that when there are four evenly distributed vents 112 and four vent grooves 212, the preferred rotation angle can be set to 45°, simply ensuring that the vents 112 and vent grooves 212 are completely staggered. After staggering, there is no airflow path between the vent 112 and the vent groove 212 (the theoretical value of the through-hole area is zero), achieving a contact seal. Preferably, as... Figure 5 , Figure 6As shown, the exhaust channel formed by the vent groove 212 and the vent 112 is fully connected in the initial installation state. At this time, the air inside the temperature measuring chamber 230 can be discharged through the radially arranged vent grooves 212 and the vent 112, preventing the edge of the adhesive part 200 from lifting due to air accumulation. After the exhaust is completed, rotate the cover plate 110 to the locked position, and the vent 112 is blocked by the solid area between the vent grooves 212, forming a sealed space to maintain temperature measurement stability. The bottom edge of the base 210 of the adhesive part 200 is provided with two long strip-shaped limiting grooves 250. The limiting grooves 250 are arranged in parallel and open at both ends. A strip-shaped adhesive tape 240 with a matching shape and area can be inserted into the groove. The surface of the adhesive tape 240 is covered with a peelable protective film, and the bottom surface of the adhesive tape 240 is coated with an adhesive layer. After being inserted into the limiting groove 250 and the protective film is removed, its adhesive surface is flush with the bottom surface of the base 210.

[0036] Preferably, the sum of the depth of the receiving hole 211 and the thickness of the temperature measuring cavity 230 is less than the height of the temperature measuring head 120, ensuring that the bottom of the temperature measuring head 120 protrudes from the bottom surface of the base 210 after insertion, thereby directly contacting the skin surface for efficient temperature measurement. The protrusion height of the temperature measuring head 120 needs to adapt to different skin curvatures to ensure sufficient contact pressure at all wearing locations to meet measurement accuracy requirements. A preferred height range is 0.5–1.5 mm, suitable for measurements on areas such as the forehead or armpit.

[0037] Preferably, the temperature sensor integrated in the temperature measuring head 120 is connected via a wire to a wireless transmission module (such as Bluetooth, Wi-Fi, or RF) inside the temperature measuring section 100 (or cover plate 110). Temperature data is transmitted wirelessly to an external device, such as a smartphone or tablet, in real time. Wireless transmission is existing technology and will not be described further here. According to another preferred embodiment, an electronic display screen can be integrated on the top of the cover plate 110 of the temperature measuring section 100. A thin-film temperature sensor is embedded in the temperature measuring end face of the temperature measuring head 120, and its signal output pin extends upward along the inner wall of the temperature measuring head 120 to the inner layer of the cover plate 110 via a flexible FPC cable. This cable can bypass the mounting position of the vent 112 and finally connect to the display driver board integrated on the top of the cover plate 110. A button battery is embedded in the inner layer of the cover plate 110, and its positive and negative terminals are connected to the power input terminal of the display driver board through a stamped metal spring. The display area and the notch 113 are spatially offset, which avoids obstructing the area where fingers apply pressure while enabling visualization of temperature data. After the user rotates the cover 110 to complete the negative pressure seal, the body temperature value can be read directly through the screen without relying on external devices, which is especially suitable for patients with limited mobility or who cannot operate smart terminals.

[0038] Preferably, if the temperature measuring part 100 needs to be replaced or its position adjusted during use, the cover plate 110 can be rotated in the reverse direction to disengage the protrusion 111.1 from the recess 223, allowing the connector 111 to move in the reverse direction along the rotating groove 222 to the positioning hole 221 and then be pulled out vertically. The adhesive part 200 can be left alone on the skin surface, maintaining local breathability through the ventilation groove 212 to avoid skin discomfort caused by long-term adhesion. When rotating the cover plate 110, the user applies torque by pinching the anti-slip texture at the recess 113 with their fingers. The frictional resistance generated by the texture prevents slippage and ensures precise and controllable rotation. When disassembling the mushroom-head snap-fit ​​structure between the connector 111 and the rotating groove 222, a vertical pulling force needs to be applied. At this time, the spherical head is squeezed and deformed, allowing it to come out from the positioning hole 221, achieving quick separation without damaging the components. The strip design of the adhesive tape 240 allows for selection of the number and position of installations as needed. The guiding action of the limiting groove 250 ensures that the adhesive tape 240 is aligned with the edge of the base 210, maintaining the flatness of the overall structure.

[0039] In this embodiment, the temperature patch achieves the dual functions of opening and closing the exhaust channel and mechanical locking through the rotation linkage mechanism between the cover plate 110 and the base 210. The sliding path of the connector 111 within the rotating groove 222 precisely limits the rotation angle, and the self-locking engagement of the protrusion 111.1 and the recess 223 provides clear feedback upon positioning. The closed state of the temperature measuring chamber 230 effectively isolates the external environment from affecting the temperature measuring accuracy, while maintaining adequate breathability between the adhesive part 200 and the skin. The modular design allows the cover plate 110 of the temperature measuring part 100 to be reused, while the adhesive tape 240 of the adhesive part 200 can be replaced separately as a consumable, reducing usage costs.
