Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this specification are within the protection scope of this utility model.

[0027] Furthermore, in the embodiments of this specification, when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present.

[0028] Please see Figure 1-2 This embodiment provides a temperature-controlled medical liquid heating device, which includes a heating shell 1, a first groove 11 for accommodating a mannitol bottle, a plurality of second grooves 12 for accommodating syringes, and a plurality of third grooves 13 for accommodating bagged saline; and a heating assembly 2, which includes a plurality of heating elements, three displays 21, and three controllers. The heating elements are respectively arranged in the first groove 11, each of the second grooves 12, and each of the third grooves 13. The three displays 21 are electrically connected to the three controllers, and the three controllers are electrically connected to the heating elements in the first groove 11, the second groove 12, and the third groove 13.

[0029] Specifically, the device can heat the mannitol bottle, syringe, and medication bag separately. Before injection, the medication needs to be heated to maintain a temperature close to the patient's body temperature, reducing injection discomfort. The mannitol bottle is placed in the first groove 11, and a first controller connected to the heating element in the first groove 11 controls the heating element to heat the mannitol bottle within the first groove 11. The second groove 12 is shaped to fit the syringe. After the syringe is filled with medication, it is inserted into the second groove 12. A second controller connected to the heating element in the second groove 12 controls the heating element to heat the syringe within the second groove 12. Multiple second grooves 12 can simultaneously heat multiple syringes. A syringe is heated, and a drug bag is placed in the third groove 13. A third controller connected to the heating element in the third groove 13 controls the heating element to heat the drug bag in the third groove 13. Multiple third grooves 13 can heat multiple drug bags simultaneously. Three displays 21 can display the on / off status of the three sets of heating elements. This device can independently heat different drug containers to meet the heating needs of different drugs. For example, the drugs used in gastric lavage and nasal lavage have different packaging methods and can be heated using this device. At the same time, except for mannitol bottles, multiple syringes and drug bags can be heated simultaneously, improving heating efficiency, reducing the workload of medical staff, and reducing patient discomfort during injection. For mannitol bottles, the heating element in the first recess 11 usually needs to be heated to 45°C, and its controller is set to maintain 45°C. For nasal irrigation, the heating element in the second recess 12 needs to be maintained at around 37°C. For gastric lavage, the heating element in the third recess 13 needs to be maintained at 38°C. In actual clinical practice, the temperature of the heating element can be controlled by the controller.

[0030] In some possible embodiments, the heating housing 1 is a rectangular body, the first groove 11 is a cylindrical groove, the second groove 12 is a cylindrical groove, the bottom of the second groove 12 is provided with a bottom groove 121 adapted to the injection head of the syringe, and the third groove 13 is a rectangular groove. The first groove 11 is arranged in the middle of the upper surface of the heating housing 1, a plurality of second grooves 12 are arranged along the circumference of the first groove 11, a plurality of third grooves 13 are respectively arranged on both sides of the upper surface of the heating housing 1, and three displays 21 are spaced apart on one side of the heating housing 1.

[0031] Specifically, the mannitol bottle is cylindrical, and the first groove 11 is adapted to its shape, allowing the mannitol bottle to be placed vertically inside. The second groove 12 is a cylinder adapted to the syringe. After the syringe draws up the liquid, the syringe head is covered and the syringe is placed vertically into the second groove 12. The liquid bag is tilted and stands obliquely in the rectangular third groove 13. The first groove 11, the second groove 12, and the third groove 13 are arranged according to their size, resulting in a reasonable and aesthetically pleasing layout that improves space utilization within a certain space.

[0032] In some possible implementations, the heating assembly 2 also includes three sets of control buttons 22, which are electrically connected to three controllers respectively, and are arranged below the three displays 21 respectively.

[0033] Specifically, the heating components 2 in the first groove 11, the second groove 12 and the third groove 13 are controlled by three sets of control buttons 22, which change the heating temperature of the heating components 2 according to different usage scenarios.

[0034] In some possible implementations, the heating element includes a PTC ceramic heating element, and several groups of PTC ceramic heating elements are arranged along the inner sidewalls of the first groove 11, the second groove 12 and the third groove 13 respectively. The inner sidewalls of the first groove 11, the second groove 12 and the third groove 13 are respectively covered with insulating pads 14.

[0035] Specifically, the PCT ceramic heating element has a fast heating speed, high thermal efficiency and no risk of combustion. The insulating pad 14 conducts heat to the liquid medicine in the groove. The insulating pad 14 is relatively soft and will not cause wear to the medicine bottle or medicine bag due to friction.

[0036] In some possible implementations, a temperature sensor is provided on the inner side of each insulating pad 14, and the temperature sensors in the first groove 11, the second groove 12 and the third groove 13 are electrically connected to the corresponding three controllers.

[0037] Specifically, the temperature sensor is located inside the insulating pad 14 and is in contact with the medicine bottle, syringe or medicine bag to monitor the temperature of the medicine in real time. The temperature is displayed on the display 21 by the controller. At the same time, the controller controls the heating element in real time according to the temperature monitored by the temperature sensor to ensure that the temperature of the medicine reaches the required level and remains constant.

[0038] In some possible implementations, a pressure sensor is provided at the bottom of each second groove 12 and each third groove 13, and the pressure sensor in the second groove 12 and the pressure sensor in the third groove 13 are electrically connected to two corresponding controllers.

[0039] Specifically, there are multiple second grooves 12 and third grooves 13. The amount of medicine to be heated varies each time it is used, so only a few second grooves 12 or third grooves 13 may be used. However, multiple second grooves 12 or third grooves 13 are controlled by a single controller. If all grooves of the same type are working when only a few are in use, it will lead to waste, as some grooves will remain unused and continue to generate heat. Pressure sensors are installed in the second grooves 12 and third grooves 13. Each pressure sensor is electrically connected to the controller that controls the heating element in the groove. When medicine is placed in the groove, the pressure sensor transmits a signal to the controller, which then controls the heating element in the groove corresponding to the pressure sensor to work, thereby improving utilization.

[0040] In some possible implementations, an anti-slip pad 15 is provided at the bottom of the first groove 11. A power cord 3 is connected to the heating housing 1, and several PTC ceramic heating elements and three displays 21 are electrically connected to the power cord 3, which is connected to an external power source for power supply.

[0041] Specifically, the anti-slip pad 15 at the bottom of the first groove 11 further restricts the position of the mannitol bottle; each electrical component of the device is powered by an external power source connected to the power cord 3, resulting in a large overall power demand. By using an external power source, the overall size of the device can be reduced, the need for batteries can be reduced, and costs can be lowered.

[0042] In some possible implementations, the heating housing 1 is made of medical-grade engineering plastic.

[0043] Specifically, medical-grade engineering plastics are high-performance engineering plastics designed specifically for the medical field, possessing excellent biocompatibility, chemical resistance, and mechanical strength. The material is lightweight and chemically stable, and will not be damaged by heating elements.

[0044] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this utility model; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
