Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a liquid leakage alarm patch. Background Technology

[0002] Wound dressings are a new type of medical dressing that incorporates sensors and a microprocessor to monitor the temperature, humidity, and swelling around the wound, issuing alarms when abnormalities occur. During wound healing, swelling can occur due to fluid accumulation and leakage, which can even lead to skin necrosis in severe cases. Wound dressings can monitor the wound's condition in real time, ensuring that swelling remains within a specified range. If swelling exceeds this range, an alarm is triggered to alert doctors for timely intervention, thereby improving the patient's treatment outcome and quality. However, due to the different types of wounds, some wounds may experience fluid leakage during swelling, leading to contamination of the dressing. Since the sensors and microprocessor are adhered to the dressing, they are difficult to separate clinically, requiring replacement of the entire dressing. For example, Chinese patent CN208809228U discloses a liquid extravasation dressing alarm device, including a dressing body and an alarm device. A hemostatic pad is located in the middle of the lower surface of the dressing body. The alarm device includes a shell, a probe, a wire, an LED warning light, a PCB board, and an alarm buzzer. The probe is respectively located on both sides of the hemostatic pad. One end of the wire is electrically connected to the PCB board, and the other end passes through the upper surface of the dressing body to the lower surface and is electrically connected to the probe. This patent features a medical pressure sensor on one side of the hemostatic pad of the dressing body. When liquid extravasation causes skin swelling, or when liquid leaks to both sides of the hemostatic pad during intravenous infusion, an alarm is triggered by the LED warning light and the alarm buzzer, promptly alerting those nearby to the liquid extravasation and allowing for timely intervention. However, due to the long wound healing time, the medical pressure sensor located on one side of the hemostatic pad is still at risk of contamination during continuous liquid extravasation, leading to frequent replacement of the entire dressing device, increased costs, and reduced effectiveness.

[0003] Therefore, it is necessary for those skilled in the art to provide a liquid leakage alarm dressing that absorbs the fluid that seeps out during wound swelling, reduces the contamination of the pressure sensing area by the fluid, and extends the service life of the device. Utility Model Content

[0004] The purpose of this invention is to provide a liquid leakage alarm dressing to solve the technical problem in the prior art where fluid seeps out during wound swelling, contaminating the dressing and its sensor, resulting in a short dressing lifespan.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a liquid leakage alarm patch, including a patch body, a power supply part and a connecting wire for connecting the patch body and the power supply part. The patch body has a groove in the middle, and a sensor and a liquid-absorbing layer are provided in the groove. The liquid-absorbing layer is ring-shaped and sleeved on the outside of the sensor. An elastic film is provided on the inner ring of the liquid-absorbing layer. A gap is left between the elastic film and the sensor. The sensor is sealed in the inner ring of the liquid-absorbing layer.

[0006] Furthermore, the elastic film is made of silicone film with a thickness of less than 0.1 mm.

[0007] Furthermore, the thickness of the liquid-absorbing layer is greater than the thickness of the sensor.

[0008] Furthermore, the absorbent layer is made of diatomaceous earth, and the surface of the absorbent layer facing the wound has protrusions, which are multiple and evenly distributed on the absorbent layer.

[0009] Furthermore, the absorbent layer has a composite structure, comprising a contact layer and an elastic layer.

[0010] Furthermore, the contact layer is made of diatomaceous earth, and the elastic layer is made of rubber.

[0011] Furthermore, the absorbent layer has a composite structure, comprising a contact layer and a flexible layer.

[0012] Furthermore, the contact layer is made of diatomaceous earth, and the flexible layer is made of tin.

[0013] Furthermore, the power supply unit includes a battery and a buzzer, with the battery electrically connected to the buzzer.

[0014] The beneficial effects of this invention are as follows: An elastic film is added to the dressing body to isolate exudate from the sensor, thus preventing sensor contamination and extending the lifespan of the invention. Simultaneously, an ointment is applied to the surface of the elastic film that contacts the wound to aid healing. When exudate occurs from a wound, it mixes with the ointment. Because the elastic film has a smooth surface, it can be reused simply by wiping away the contaminated ointment and applying new ointment, greatly improving wound healing.

[0018] The components in the attached diagram are labeled as follows: 10, Adhesive body; 11, Sensor; 12, Liquid-absorbing layer; 13, Protrusion; 14, Elastic film; 20, Power supply; 21, Connecting wire. Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please see Figure 1 This utility model provides a leak-proof alarm patch, including a patch body 10, a power supply unit 20, and a connecting wire 21 for electrically connecting the patch body 10 and the power supply unit 20. The patch body 10 includes a sensor 11 and a patch. The surface of the patch facing the human body is coated with adhesive, and the sensor 11 is attached to the human body using the patch to ensure stable adhesion. The power supply unit 20 includes a battery, a controller, and a buzzer. The battery is electrically connected to the controller, and the buzzer and sensor 11 are respectively electrically connected to the controller to control the sensor 11.

[0021] Further, please refer to Figure 2 , Figure 3 The dressing body 10 has a groove 15 in the middle, and a sensor 11 and an absorbent layer 12 are arranged in the groove 15. The absorbent layer 12 is annular and fits around the sensor 11. The thickness of the absorbent layer 12 is greater than the thickness of the sensor 11. Thus, when in use, the sensor 11 is recessed in the absorbent layer 12. When the absorbent layer 12 is attached to the human body, the swollen part of the wound is directly facing the sensor 11. Since the wound itself has a certain degree of swelling, the sensor 11 recessed in the absorbent layer 12 can effectively avoid direct contact with the wound during installation, prevent accidental activation, and improve the accuracy of detection.

[0022] In this embodiment, the sensor 11 is a commercially available flexible thin-film pressure-sensitive sensor. This sensor is a type of flexible thin-film sensor whose resistance decreases as the pressure applied to the sensing area increases. It is composed of a polyester film with excellent overall mechanical properties, a highly conductive material, and a nanoscale pressure-sensitive material. The top layer consists of a flexible thin film and a pressure-sensitive layer laminated thereon, while the bottom layer consists of a flexible thin film and conductive circuitry laminated thereon. When the flexible thin-film pressure-sensitive sensor operates under pressure, it functions as a two-port variable resistor whose resistance is controlled by pressure. The changing resistance value needs to be converted into a voltage signal that can be recognized by the processor.

[0023] Furthermore, an elastic film 14 is provided on the inner ring of the absorbent layer 12. The elastic film 14 includes, but is not limited to, a silicone film. The silicone film has a thickness of less than 0.1 mm and has good air permeability and elasticity. A gap is left between the elastic film 14 and the sensor 11, sealing the sensor 11 in the inner ring of the absorbent layer 12. In use, the elastic film 14 is attached to the wound on the human body. When the wound swells, the elastic film 14 is squeezed and bulges along with the wound, finally abutting against the sensor 11 to realize signal transmission. When the human wound oozes fluid, the elastic film 14 is used to isolate the exudate outside the sensor 11, thereby preventing the sensor 11 from being directly contaminated and improving the service life of this utility model.

[0024] In this embodiment, the surface of the elastic film 14 that contacts the wound is coated with ointment to help the wound heal and greatly improve the wound healing effect.

[0025] Furthermore, the material of the absorbent layer 12 includes, but is not limited to, diatomaceous earth. The absorbent layer 12 has good liquid absorption function and also has a certain antibacterial effect, ensuring that wound exudate cannot flow out and reducing contamination. The surface of the absorbent layer 12 facing the wound has protrusions 13. Multiple protrusions 13 are evenly distributed on the absorbent layer 12. The protrusions 13 are used to ensure ventilation of the wound, reduce bacterial growth, and increase the coefficient of friction between the absorbent layer 12 and the human body, preventing it from falling off.

[0026] In another embodiment, the absorbent layer 12 has a composite structure, comprising a contact layer and an elastic layer. The contact layer is made of a material with good absorbency, such as diatomaceous earth, to contact and absorb exudate. The elastic layer is made of rubber, which gives the absorbent layer 12 a certain degree of elasticity, ensuring that the absorbent layer 12 can better conform to the human body under the action of the dressing.

[0027] In other embodiments, the absorbent layer 12 has a composite structure, comprising a contact layer and a flexible layer. The contact layer is made of a material with good absorbency, such as diatomaceous earth, to contact and absorb exudate. The flexible layer is made of a material that cannot return to its original shape after the force is lost, such as tin. This allows the contact layer and the flexible layer to deform and maintain their deformed state after the absorbent layer 12 is pressed onto the wound. After the dressing is removed, the contact layer can still maintain contact with the wound under the action of the flexible layer, thereby improving stability and ensuring the dressing effect.

[0028] The specific operation method of this utility model is as follows: apply the ointment to the elastic film 14 on the dressing body 10, then attach the dressing body 10 to the wound, press the dressing body 10 tightly and connect it to the power supply part 20, adjust the dressing body 10, and complete the installation.

[0029] This invention adds an elastic film 14 to the dressing body 10. The elastic film 14 isolates exudate from the sensor 11, thus preventing contamination and extending the lifespan of the invention. Simultaneously, an ointment is applied to the surface of the elastic film 14 that contacts the wound to aid healing. When exudate occurs from the wound, it mixes with the ointment. Because the elastic film 14 has a smooth surface, it can be reused simply by wiping away the contaminated ointment and applying new ointment, greatly improving wound healing.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
