Description

Technical Field

[0001] The present invention relates to the technical field of pet products, and in particular to a constant temperature circulation pet post-operative rehabilitation therapy pad and a use method thereof. Background Art

[0002] With the continuous advancement of pet healthcare, postoperative rehabilitation care has become a crucial component of pet health management. Traditional pet postoperative care pads typically utilize resistance wire heating technology, which suffers from slow heating rates, large temperature fluctuations, and high energy consumption. This makes it difficult to meet the precise constant temperature requirements of pets after surgery. Furthermore, pets often experience frequent changes in body position due to pain, anxiety, and other behaviors, further complicating temperature control.

[0003] Traditional electric heating pads are inconvenient to use. After a few normal uses, the resistance wire will break and the heating effect will be lost. The regulation is not accurate. When heated for a short time, the temperature will rise too high and burn the pet's skin, resulting in hair loss that is difficult to heal.

[0004] In recent years, the integration of new material technologies and intelligent control technologies has provided a new path for innovation in pet medical equipment. Graphene, a two-dimensional carbon nanomaterial, has gradually been used in the field of medical heating due to its excellent electrothermal properties (excellent electrothermal conversion efficiency), flexibility, and biocompatibility. However, a single graphene heating layer still faces the problem of temperature fluctuations and needs to be combined with heat storage technology to achieve precise heat regulation. Semiconductor phase change materials (PCMs) absorb or release large amounts of latent heat through the solid-liquid phase transition process, becoming a key technology for maintaining temperature stability. Integrated applications based on heating systems are still a blank in the field of pet medicine. Summary of the Invention

[0005] The main purpose of the present invention is to provide a constant temperature circulation pet postoperative rehabilitation therapy pad that can effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A constant temperature circulation pet postoperative rehabilitation therapy pad, comprising a therapy pad body, a protective shell, a PID control module, and a data cable. The therapy pad body is wrapped with a protective shell, a PID control module is disposed at a corner of the protective shell, a temperature sensor is disposed next to the PID control module, a sensor probe is disposed at the front end of the temperature sensor, the sensor probe passes through the protective shell and is inserted into the therapy pad body, and a calming aromatherapy box is disposed in the middle of the side of the protective shell.

[0008] The surface of the main body of the physiotherapy pad is provided with an antibacterial silicone pad, the antibacterial silicone pad is tightly attached to the graphene heating layer, a PCM heat storage layer is provided at the lower end of the graphene heating layer, a honeycomb heat storage structure is provided in the middle of the PCM heat storage layer, a pressure sensing pad is provided at the lower end of the PCM heat storage layer, and the side of the pressure sensing pad is connected to the PID control module via a data cable;

[0009] The sensor probes cover the entire area of the main body of the physiotherapy pad, and the internal sensor probes are spaced 5 centimeters apart. The internal sensor probes transmit the collected temperature information back to the temperature sensor via a data line.

[0010] Preferably, the rear end of the PID control module is connected to the positive and negative electrodes of the graphene heating layer through wires passing through the protective shell, the side of the PID control module is connected to the temperature sensor through a data line, and the front end of the PID control module is connected to the power connector through wires.

[0011] Preferably, the calming aromatherapy box comprises a storage box, a porous plate is provided at the upper end of the storage box, and an aromatherapy liquid filling port is provided at one corner of the porous plate.

[0012] Preferably, the storage box can be filled with different sedatives from the aromatherapy liquid filling port as needed.

[0013] Preferably, a layer of insulation protection is provided between the outer layer of the graphene heating layer and the connection position of the wires, and hexagonal patterns are provided on the surface of the antibacterial silicone pad.

[0014] Preferably, the PID control module can be remotely connected to set the temperature threshold.

[0015] Preferably, the customized composite PCM used in the PCM heat storage layer has a phase change temperature of 38°C.

[0016] Preferably, when the temperature of the main body of the therapy pad continues to drop below the temperature threshold of 2° C. and the data sent back by the pressure sensing pad remains stable, the PID control module energizes the graphene heating layer again.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention uses a pressure sensing mat to sense pressure changes and transmits the data to a PID control module. The PID control module energizes the graphene heating layer via wires, and a temperature sensor collects temperature changes in the therapy mat. When the temperature reaches a threshold set in the PID control module, the PID control module stops supplying power to the graphene heating layer. When the temperature of the main body of the therapy mat reaches a threshold of 2 degrees, heating is resumed, achieving intelligent control.

[0019] The present invention sets up a PCM heat storage layer. The PCM heat storage layer uses a customized composite PCM with a phase change temperature of 38°C and a honeycomb structure design to absorb excess heat. When the graphene heating layer stops heating, the PCM phase change dissipates heat to maintain a constant temperature, thereby realizing heat recycling.

[0020] The stable properties of the graphene heating layer provided in the present invention ensure its safe use. The PID control module and temperature sensor provided at the same time will further limit the temperature of the graphene heating layer from exceeding the temperature threshold, thereby ensuring its safety. As a result, its use is further expanded, and it can be used as a heating pad on an operating table, as a postoperative rehabilitation pad, as a pad for young pets, and for many other purposes as needed.

[0031] Example

[0032] See also Figure 1-6 , the present invention provides a technical solution:

[0033] The present invention discloses a constant temperature circulation pet postoperative rehabilitation therapy pad, comprising a therapy pad body, a protective shell, a PID control module, and a data cable. The outer layer of the therapy pad body is wrapped with the protective shell, the PID control module is arranged at a corner of the protective shell, a temperature sensor is arranged next to the PID control module, a sensor probe is arranged at the front end of the temperature sensor, the sensor probe passes through the protective shell and is inserted into the therapy pad body, and a calming aromatherapy box is arranged in the middle of the side of the protective shell;

[0034] The surface of the main body of the physiotherapy pad is provided with an antibacterial silicone pad, the antibacterial silicone pad is tightly attached to the graphene heating layer, a PCM heat storage layer is provided at the lower end of the graphene heating layer, a honeycomb heat storage structure is provided in the middle of the PCM heat storage layer, a pressure sensing pad is provided at the lower end of the PCM heat storage layer, and the side of the pressure sensing pad is connected to the PID control module via a data cable;

[0035] The sensor probes cover the entire area of the main body of the physiotherapy pad, and the internal sensor probes are spaced 5 centimeters apart. The internal sensor probes transmit the collected temperature information back to the temperature sensor via a data line.

[0036] In this embodiment, the rear end of the PID control module is connected to the positive and negative electrodes of the graphene heating layer through wires passing through the protective shell, the side of the PID control module is connected to the temperature sensor through a data line, and the front end of the PID control module is connected to the power connector through wires. The PID control module directly controls the current on and off of the graphene heating layer, and the wires pass through the protective shell to prevent short circuits caused by pets chewing. The temperature sensor samples data at a frequency of 10Hz and transmits it to the PID control module via the data line to ensure that the temperature fluctuation is <±0.5℃.

[0037] In this embodiment, the calming aromatherapy box includes a storage box, a porous plate is provided on the upper end of the storage box, and an aromatherapy liquid filling port is provided at a corner of the porous plate. The uniform volatilization of the sedative is utilized to reduce the activity of the pet after surgery, achieve physical rest, and accelerate recovery.

[0038] In this embodiment, the storage box can be filled with different sedatives from the aromatherapy liquid filling port as needed, such as catnip (Feline-friendly), dog lavender essential oil, etc., but the type and use of the sedative must be selected by the veterinarian through professional knowledge.

[0039] In this embodiment, a layer of insulation protection is provided between the outer layer of the graphene heating layer and the connection position of the wires. The surface of the antibacterial silicone pad is provided with hexagonal patterns. The insulation protection adopts Parylene nano-coating with an insulation strength of >5kV / mm to prevent leakage caused by pets licking. The setting of the hexagonal patterns ensures air circulation at the contact position when the pet lies on the antibacterial silicone pad.

[0040] In this embodiment, the PID control module can remotely connect to set the temperature threshold, and connect to the mobile phone APP via Bluetooth 5.0 or Wi-Fi, so that the user can adjust the temperature in real time.

[0041] In this embodiment, the customized composite PCM used in the PCM heat storage layer has a phase change temperature of 38°C.

[0042] In this embodiment, when the temperature of the main body of the therapy pad continues to drop below the temperature threshold of 2° C. and the data sent back by the pressure sensing pad remains stable, the PID control module energizes the graphene heating layer again.

[0043] Specific implementation process

[0044] Step 1: Before Use: Inspect the device's integrity, ensuring the protective housing is intact and all components are securely connected. Clean the antibacterial silicone pad with pet wipes to avoid chemical residue. Open the Calming Aromatherapy Diffuser's storage container and fill it with a veterinarian-recommended sedative (such as catnip or lavender essential oil for dogs) through the aromatherapy liquid filling port, not exceeding 80% of the capacity.

[0045] Step 2: Connect Power and Initialize Settings: Plug the power connector into a standard power outlet. Pair the PID control module with the mobile app via Bluetooth 5.0 or Wi-Fi. Set the target temperature threshold in the app (recommended initial value: 38°C, consistent with the phase transition temperature of the PCM heat storage layer). Confirm the PID parameters: temperature fluctuation tolerance ±0.3°C, and set the heating layer response time delay to 3 seconds (to prevent frequent starts and stops).

[0046] Step 3: After the device is powered on, the pressure sensor pad reports a pressure change, energizing the graphene heating layer and allowing the PCM heat storage layer to absorb heat. The temperature sensor samples data at a 10Hz frequency, and the data is transmitted in real time to the PID control module via a data cable. When the heat storage layer temperature reaches 38°C, the PID control module enters a constant temperature maintenance state.

[0047] Step 4: Pet Use Phase: Guide or place the pet on the therapy mat. Once the pressure sensing pad detects a continuous pressure signal (5N), the PID control module activates the heating function of the graphene heating layer. Simultaneously, the aromatherapy molecules in the calming aromatherapy box diffuse evenly through the porous plate, creating a constant temperature environment that reduces the pet's stress response and minimizes post-operative activity. The PCM heat storage layer achieves a bidirectional thermal cycle through its honeycomb structure: it absorbs heat when the surface temperature is above 38°C and releases heat when it is below 36.7°C, maintaining a stable surface temperature. Aromatherapy liquids must be selected under veterinary guidance, and mixing different types of sedatives is prohibited.

[0048] Step 5: Intelligent temperature control operation When the pet moves and causes the local temperature to drop: the temperature sensor detects that the temperature in a certain area is 0.5℃ lower than the set value. The PID control module calculates the temperature difference change rate and dynamically adjusts the current intensity of the graphene heating layer. The heating layer prioritizes local compensatory heating of the low-temperature area. When the overall temperature continues to drop by more than 2℃ and the pressure sensor pad data is stable (fluctuation <10%): the PID control module automatically restarts the graphene heating layer to heat the PCM heat storage layer at full power and synchronously releases stored heat to assist in warming. When the overall temperature continues to drop by more than 2℃ and the pressure sensor pad data approaches zero, the PID control module disconnects the power supply of the graphene heating layer and stops working.

[0049] Step 6: Post-use maintenance: Disconnect the power supply and wipe the surface after the device cools down. To clean the aromatherapy box: Pour any remaining liquid into a designated container. Wipe the inside of the storage box with 75% medical alcohol. Keep the porous plate dry to prevent clogging. Check the integrity of the graphene heating layer insulation coating monthly. Contact after-sales service immediately if any damage is found.

[0050] The present invention discloses a constant temperature circulation pet postoperative rehabilitation therapy pad. The pressure sensing pad senses the pet's body pressure to trigger the PID control module, driving the graphene heating layer and the PCM heat storage layer to work together, and uses the honeycomb structure of the customized phase change material of 38°C to realize a two-way thermal cycle - when the temperature reaches the threshold, the heat storage layer absorbs heat and stores energy, and releases heat to maintain a constant temperature when the temperature drops by 2°C. At the same time, combined with the veterinary-guided calming aromatherapy diffusion function, coordinated with 10Hz high-frequency temperature sampling and ±0.5°C precise temperature control algorithm, the heating current is dynamically adjusted when the pet's activity causes a local temperature difference, and a 3-second response delay is set to prevent frequent start and stop. Before use, the integrity of the equipment needs to be checked, the antibacterial surface needs to be cleaned, and the specified aromatherapy liquid needs to be injected. After use, the aromatherapy box needs to be disinfected with alcohol and the insulation layer of the heating layer needs to be tested monthly, forming a rehabilitation nursing pad that integrates intelligent temperature control, stress relief, and postoperative care.
