Description

Technical Field

[0001] This invention relates to a constant temperature heating device, specifically to the field of medical technology. Background Technology

[0002] With the rapid advancement of medical technology, clinical medicine is placing increasingly stringent requirements on the operating environment of medical equipment, while also prioritizing patient comfort. Existing medical irrigation solutions are exposed to air during the pouring process from their original packaging into the heating device, leading to contamination and increased surgical risks. Furthermore, current irrigation solutions have low heating efficiency and unstable temperatures, resulting in poor patient comfort. A new constant-temperature heating device provides sterile, constant-temperature irrigation, significantly improving patient comfort. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems and shortcomings of the existing technology by designing a constant temperature heating device that features rapid heating, precise temperature control, and prevents bacterial contamination of the rinsing solution.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A constant temperature heating device includes a housing, a touch screen, operation buttons, a heating and temperature control chamber, a temperature sensor, a flushing fluid sensor, an infrared heating lamp, a cooling fan, a main control board, and a flushing fluid holder. The housing has a one-sided door with a handle that automatically locks when closed. A touch screen is installed at the front of the housing, allowing direct parameter adjustment. Operation buttons are located below the touch screen, also allowing direct parameter adjustment. A flushing fluid holder is located inside the heating and temperature control chamber, fixed to the bottom of the housing at a 45- to 90-degree angle. The flushing fluid holder has at least one compartment and a device for securing a flushing fluid bottle or bag. The bottom of each compartment has a groove to prevent flushing fluid from slipping out. A temperature sensor and a flushing fluid sensor are installed. When flushing fluid is placed on the flushing fluid support chamber simultaneously, at least one infrared heating lamp is installed on the rear wall of the box behind each flushing fluid support. The main control board is placed above the flushing fluid support via a bracket. When the main control board receives instructions from the flushing fluid sensor and the temperature sensor that rapid heating of the current flushing fluid is required, the main control board controls the infrared heating lamp to operate at a higher power. When the current heating chamber needs to be kept at a constant temperature, the main control board controls the infrared heating lamp to operate at a lower power. When multiple bottles of flushing fluid are placed simultaneously, the main control board determines whether the flushing fluid in each constant temperature chamber needs rapid heating or constant temperature based on the temperature data measured by the temperature sensors below each chamber. Based on the determination result, the main control board controls the power of the infrared heating lamp in the constant temperature chamber to adjust the flushing fluid temperature.

[0006] The touch screen or operation buttons control the power of the infrared heating lamps via the main control board to generate heat for heating or maintaining the temperature of the flushing fluid. The temperature sensor monitors the temperature of the flushing fluid in the chamber in real time and feeds the data back to the main control board. The main control board has data analysis and adjustment settings, and dynamically adjusts the infrared heating lamps based on the data from the temperature sensor. Once the flushing fluid temperature reaches the target temperature, the main control board controls the infrared heating lamps to enter a constant temperature mode with a lower power. In addition, the flushing fluid sensor controlled by the main board can detect whether there is flushing fluid in the heating chamber. The heating lamps cannot be turned on when there is no flushing fluid, thus ensuring the safety of the heating system. The cooling fan is located on one side of the chamber. When the temperature inside the heating constant temperature chamber is too high, the cooling fan controlled by the main control board turns on in cooling mode to extend the equipment life.

[0007] The aforementioned constant temperature heating device can complete the heating work without direct contact with the rinsing liquid, and has the functions of rapid heating and constant temperature. It uses an infrared heat source to heat the rinsing liquid, and adopts closed-loop feedback control and human-machine interaction through a touch screen or operation buttons.

[0008] The beneficial effects achieved by this invention are as follows:

[0009] The flushing fluid holder has an angled design and a device to secure the flushing fluid bottle or bag, preventing it from slipping.

[0010] Infrared light carries a high energy density and heats up quickly.

[0011] It offers two operation methods: touch screen and operation buttons, making it more user-friendly.

[0012] The control circuit adopts closed-loop control and is equipped with an automatic locking device when the handle is closed, which ensures safety and more precise temperature control.

[0013] The bottom of the flushing fluid support compartment has a groove to prevent the flushing fluid from slipping out.

[0014] It has both rapid heating and constant temperature functions, which can meet a variety of usage scenarios.

[0015] The heated constant temperature chamber can heat multiple bottles of rinsing solution simultaneously, improving work efficiency and meeting the needs of scenarios with large usage volumes.

[0016] Cooling fans can significantly reduce the surface temperature of circuits during operation, thus extending the lifespan of the equipment. Attached Figure Description

[0022] The invention will now be further described with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the invention and should not be construed as limiting the scope of protection of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] according to Figure 1 - 4, a constant temperature heating device, including a housing 1, a touch screen 2, operation buttons 3, a heating constant temperature chamber 4, a temperature sensor 5, a rinsing fluid sensor 6, an infrared heating lamp 7, a cooling fan 8, a main control board 9, and a rinsing fluid bracket 10.

[0024] Specifically, the chamber 1 adopts a side-opening door design, with a handle on one side of the door. Pulling the handle opens and closes the door to lock it in place or retrieve the flushing fluid. A touchscreen 2 is installed on the front surface of the chamber 1, displaying the real-time temperature of the internal flushing fluid. Below the touchscreen 2 are operation buttons 3, which can be used to adjust parameters. A flushing fluid holder 10 is located inside the heating and temperature control chamber 4, fixed to the bottom of the chamber at an angle of 45 to 90 degrees to the bottom. The support frame has at least one compartment. The flushing fluid support frame has a device for securing flushing fluid bottles or bags. The bottom of the flushing fluid support compartment has a groove to prevent flushing fluid from slipping. The flushing fluid to be heated is placed on the flushing fluid support frame 10. Multiple bottles of flushing fluid can be placed on the flushing fluid support frame 10 simultaneously. A flushing fluid sensor 6 is installed in the flushing fluid support frame 10 compartment to detect whether flushing fluid has been added. Subsequent heating can only proceed if flushing fluid is detected. A temperature sensor 5 is installed in the flushing fluid support frame 10 compartment to monitor the flushing fluid temperature in real time and send the data to the main control unit. An infrared heating lamp 7 is installed behind the flushing fluid holder 10 and board 9. When flushing fluid is placed in and needs rapid heating, the main control board 9 automatically controls the infrared heating lamp 7 to work, rapidly heating the flushing fluid at maximum power. When the main control board 9 receives flushing fluid temperature data from the temperature sensor 5 that equals the target temperature, the main control board 9 automatically controls the infrared heating lamp 7. For example, when heating and keeping three bottles of flushing fluid warm, each bottle is equipped with an infrared heating lamp 7. When three bottles of flushing fluid are placed in the heating device, the corresponding infrared heating lamp 7 operates at higher power when one bottle of flushing fluid is being heated. When both bottles of rinsing fluid are kept warm, the corresponding infrared heating lamp 7 operates at a lower power. When there is no heating and both are in the keep-warm state, the infrared heating lamp 7 automatically enters the constant temperature mode, i.e., the lower power mode, to maintain the constant temperature of the rinsing fluid. When the main control board 9 receives the rinsing fluid temperature data from the temperature sensor 5, which is lower than the target temperature, the main control board 9 automatically controls the corresponding infrared heating lamp 7 to increase its power, and this cycle continues. When the temperature inside the heating constant temperature chamber is higher than the set temperature, the main control board 9 controls the cooling fan 8 to start the cooling mode, so that it works in the optimal temperature environment and extends the overall service life of the equipment.

[0025] To ensure the sterility and safety of the rinsing solution, in this embodiment, an infrared heating method is preferably used, which avoids direct contact with the rinsing solution and prevents the rinsing solution from being exposed to air.

[0026] To improve heating efficiency and rapidly raise the temperature of the rinsing fluid, in this embodiment, multiple infrared heating lamps are preferably used simultaneously and can be controlled individually.

[0027] To ensure accurate temperature of the rinsing fluid, in this embodiment, it is preferable to use closed-loop control with real-time temperature information acquisition.

[0028] This invention is simple to operate:

[0029] Pull the handle on the front door of the equipment to open the door to the side.

[0030] Place the flushing fluid on the flushing fluid holder, ensuring it is securely positioned directly above the flushing fluid sensor.

[0031] Close and lock the equipment door.

[0032] Set the target heating temperature via the touchscreen or operation buttons.

[0033] After confirming that everything is correct, click the "Start Heating" button, and the device will begin working.

[0034] After heating is complete, repeat step 1 above when using the rinsing solution. Open the front door to retrieve the rinsing solution. If it is not needed for the time being, the equipment will automatically enter the constant temperature mode. You can then retrieve the solution directly when needed.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
