Abstract
Description
Technical Field
[0001] This invention relates to the field of medical assistive device technology, specifically to a medical hand heating device and its control method. Background Technology
[0002] In medical practice, especially in low-temperature operating rooms, emergency rooms, or during prolonged precision procedures (such as microscopic surgery and catheter-based interventions), healthcare workers' hands often suffer from poor blood circulation due to the cold environment or prolonged inactivity, leading to cold, stiff, and reduced dexterity. This not only affects the operator's comfort but can also impact the accuracy and efficiency of the surgery. Furthermore, in cold environments, most patients requiring intravenous puncture are prone to significant vasoconstriction due to low hand temperature, increasing the difficulty of the puncture.
[0003] Current technologies typically use electric hand warmers and chemical hand warmers to heat the hands. These methods only heat specific areas of the hands, and the temperature is difficult to control. Electric hand warmers, due to their simple on / off temperature control, experience large temperature fluctuations. Using a hand warmer that has been turned off can lead to localized overheating and burns, failing to meet medical safety standards. Furthermore, most electric hand warmers have a rectangular structure, which prevents them from effectively heating all parts of the hand, especially areas with poor peripheral circulation such as the fingertips and knuckles, resulting in poor heating performance. Summary of the Invention
[0004] In order to solve the technical problems of existing technologies that cannot heat different parts of the hand in sections and that the heating temperature is difficult to control, the present invention provides a medical hand heating device.
[0005] This invention employs the following technical solution: a medical hand heating device, comprising a base, a cover, and a controller. The base has at least one heating groove with the same shape as the hand. Multiple independently heated units are evenly distributed around the heating groove. Each heating unit includes a heating element and a temperature sensor. The temperature sensor is used to acquire the temperature of a localized area of the hand within the heating groove, and the heating element is used to heat that localized area. The cover includes a cover body and an elastic element. The cover body is mounted on the base and forms a sealed cavity with an entrance between it and the base. The elastic element is disposed within the sealed cavity and fixed to the base on all sides. An inflation cavity is formed between the elastic element and the cover body. The base also has a pair of blowers for inflating and deflating the inflation cavity. The inflation and deflating of the inflation cavity drives the elastic element to wrap or loosen the hand located within the heating groove. The controller acquires the temperature of each temperature sensor and activates the corresponding heating element when the temperature is below a set temperature threshold. The controller is also used to start the blower when more than half of the temperature sensors' temperatures are below a set temperature threshold one, and to shut off the blower when more than half of the temperature sensors' temperatures are above a set temperature threshold two. The controller is also used to shut off the corresponding heating element when the temperature exceeds a set temperature threshold three.
[0006] As a further improvement of the present invention, the heating groove includes a palm heating area and multiple finger heating areas, and a heating cavity covering the heating groove is formed between the elastic member and the base. The elastic member is fixed to the base by multiple fixing members, which are used to divide the elastic member into cavity one and multiple cavity two communicating with cavity one. The number of cavity two is the same as the number of finger heating areas, and each cavity two is connected to each finger heating area. Cavity one is connected to the palm heating area.
[0007] As a further improvement of the present invention, the side of the elastic element facing the heating groove is coated with a heat insulation layer.
[0008] As a further improvement of the present invention, the medical hand heating device also includes a power supply for supplying power to the controller, the heating unit and the blower respectively.
[0009] As a further improvement of the present invention, the base is also provided with a mounting groove, which is located below the heating groove and separated from the heating groove by a flexible fabric layer. A massage component is installed in the mounting groove, which is used to massage the hand placed in the heating groove.
[0010] As a further improvement of the present invention, the medical hand heating device also includes an external terminal. The controller is equipped with a data communication module, which communicates with the external terminal and is used to transmit the collected data to the external terminal.
[0011] As a further improvement of the present invention, a mounting component is provided on the base for fixing the base.
[0012] As a further improvement of the present invention, the heating mode of the heating unit includes a constant temperature heating mode and a cyclic pulse heating mode.
[0013] As a further improvement of the present invention, the heating units are installed inside the side wall of the heating tank, and multiple heating units are distributed at intervals inside the side wall of the heating tank. A heat-conducting layer and an antibacterial layer are sequentially coated on the side wall of the heating tank.
[0014] The present invention also includes a control method for a medical hand heating device, which employs the medical hand heating device as described above. The control method includes: acquiring the temperature of each temperature sensor and making the following judgments: if the temperature of a certain temperature sensor is less than a set temperature threshold one, then activating the heating element corresponding to that temperature sensor and deactivating the heating element when the temperature is higher than a temperature threshold three; acquiring the number of temperature sensors with temperatures lower than the set temperature threshold one and activating a blower when the number is greater than half of the total number of temperature sensors; acquiring the number of temperature sensors with temperatures higher than a set temperature threshold two and deactivating the blower when the number is greater than half of the total number of temperature sensors.
[0015] The present invention also includes a computer program product comprising a computer program that, when executed by a processor, implements the steps of the control method for the medical hand heating device described above, thereby achieving zoned heating of different areas of the hand.
[0016] The present invention also includes a storage medium storing a computer program, which, when executed by a processor, implements the steps of the control method for the medical hand heating device as described above.
[0017] The technical solution provided by this invention has the following beneficial effects: (1) The medical hand heating device provided in this solution firstly sets up multiple independent heating units in different areas of the hand, each of which is independently controlled by the controller, thus enabling zoned heating of different areas of the hand. Furthermore, the controller of this solution performs different operations by acquiring the temperature of each temperature sensor and the number of temperature sensors within different temperature threshold ranges. For example, when the overall temperature of the hand is very low, it uses a coordinated operation of elastic wrapping and heating to increase the heating speed; it can also remove the elastic wrapping and use only the heating to reduce the heating rate when the overall temperature of the hand is moderate, so as to avoid burning the hand due to excessive heating. Therefore, the medical hand heating device provided in this solution, through the sensing of temperature sensors, the decision of the controller, and the execution of the heating, enables the medical hand heating device provided in this solution to effectively achieve independent and precise temperature control of multiple areas of the hand. This design can effectively heat different areas of the hand in zones while also protecting the hand during the heating process.
[0018] (2) The medical hand heating device provided in this solution can achieve uniform heating of different parts of the hand by distributing multiple heating elements at equal intervals in the side wall of the heating tank. Combined with the control of the controller, the overall heating is more intelligent. It can heat different areas of the hand in sections, and can also heat different areas of the hand evenly, avoiding local overheating and burns to the hand. Attached Figure Description

For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.
[0026] Example 1 This embodiment provides a medical hand heating device; please refer to [reference needed]. Figures 1 to 3The device includes a base 1, a housing, a controller, and a power supply. The base 1 has at least one heating groove 11 with the same shape as a hand. Multiple heating units are evenly distributed around the heating groove 11, allowing for independent heating of the hand within the heating groove 11 in designated areas. Each heating unit includes a heating element and a temperature sensor. The temperature sensor acquires the temperature of a localized area of the hand within the heating groove 11, and the heating element heats that localized area. The housing includes a housing body 21 and an elastic element 22. The housing body 21 is fixed to the base 1 and forms a sealed cavity with an entrance, which communicates with the heating groove 11. In actual use, the hand can be inserted into the heating groove 11 through the entrance. The sealed cavity with the entrance effectively encloses the heating groove 11, reducing heat loss during heating and improving its heating efficiency. The elastic element 22 is disposed within the sealed cavity and fixed to the base 1 on all sides. One side of the elastic element 22 forms an inflation cavity 23 with the housing body 21, and the other side of the elastic element 22 forms a heating cavity 24 covering the heating groove 11. The base 1 is also equipped with a blower communicating with the inflation cavity 23. The blower is used to inflate the inflation cavity 23, driving the elastic element 22 towards the heating groove 11 to wrap the hand inside the heating groove 11. Alternatively, the blower can deflate the inflation cavity 23, driving the elastic element 22 away from the heating groove 11 to release the hand inside the heating groove 11. In practical applications, the area of the hand exposed can be changed by wrapping or releasing the hand with the elastic element 22, thereby altering the heating efficiency. Power is supplied to the blower, temperature sensor, and heating element respectively. The power source can be a high-density lithium battery, which can be installed on the base 1, and the power source can also be equipped with a USB-C interface for charging. The controller is used to acquire the temperature of each temperature sensor, and after acquiring the temperature of each temperature sensor, it performs the following operations: The controller is used to activate the heating element corresponding to any temperature sensor when the temperature of any temperature sensor is lower than threshold one, and the controller also acquires the number of temperature sensors with temperatures lower than threshold one. When the number of temperature sensors with temperatures lower than threshold one exceeds half of the total number of temperature sensors, the blower is activated to inflate the air chamber 23, so that the elastic element 22 can work in conjunction with the heating groove 11 to wrap the hand. The controller is also used to turn off the blower when more than half of the temperature sensors detect a temperature value higher than a set temperature threshold two. At this time, the elastic element 22 will move away from the hand, thereby releasing the hand. The controller is also used to turn off the heating element corresponding to the temperature sensor when the temperature is higher than a set temperature threshold three. In this scheme, the value of temperature threshold one is less than the value of temperature threshold two, and the value of temperature threshold two is less than the value of temperature threshold three. The value of temperature threshold three can be 40℃-42℃.In this solution, multiple independent heating units are first set up in different areas of the hand, each controlled independently by a controller, thus enabling zoned heating of different areas of the hand. Furthermore, the controller performs different operations by acquiring the temperature of each temperature sensor and the number of temperature sensors within different temperature threshold ranges. This design effectively acquires the temperature of different areas of the hand in zones while also combining the temperatures acquired by different heating units to understand the overall temperature of the hand. For example, if more than half of the temperature sensors detect temperatures below the first temperature threshold, it indicates that the overall temperature of the hand is low. Therefore, the blower and corresponding heating elements can be activated to heat the hand. The elastic element 22 and the heating elements work together to improve overall heating efficiency. For example, when the number of temperature sensors detecting temperatures higher than the second temperature threshold exceeds half of the total number of temperature sensors, it indicates that the overall hand temperature is relatively moderate. In this case, the blower can be turned off, but the corresponding heating element continues heating. The purpose of this design is that when the hand temperature is moderate, if the elastic element 22 is used for wrapping and the heating element for coordinated heating, the temperature may rise too quickly, causing burns. Therefore, in this solution, by turning off the blower and only activating the heating element, a slow heating process can be achieved, avoiding burns caused by excessively rapid heating. Furthermore, in actual use, the maximum heating temperature can be set between 40℃ and 42℃ to prevent burns due to excessively high heating temperatures. This entire control logic effectively achieves rapid and stable heating of the hand while protecting it during the heating process. Through temperature sensor sensing, controller decision-making, and heating element execution, the medical hand heating device provided in this solution can effectively achieve independent and precise temperature control of multiple areas of the hand.
[0027] In this solution, the specific position of the hand corresponding to each temperature sensor can be obtained by constructing a coordinate mapping relationship between the temperature sensor and the hand position, so that the controller can identify the real-time temperature corresponding to the position by obtaining the position corresponding to each temperature sensor.
[0028] The heating unit can offer two heating modes: constant temperature heating and cyclic pulse heating. In constant temperature heating mode, the controller heats the hands at a set constant temperature. In cyclic pulse mode, the hands are heated intermittently, with the duration of each intermittent heating session adjustable. In actual use, the user can select the appropriate heating mode based on the specific needs of their hands.
[0029] Heating units can be installed inside the side wall of the heating tank 11, with multiple heating units evenly distributed within the side wall of the heating tank 11. Each heating element faces the heating tank 11. By setting up the heating tank 11 and installing heating elements within its side wall, the hand located within the heating tank 11 can be effectively heated. The evenly distributed heating elements within the side wall of the heating tank 11 ensure uniform heating of different areas of the hand. Combined with controller control, the overall heating process becomes more intelligent, enabling both zoned heating of different areas of the hand and uniform heating of different areas, preventing localized overheating and burns.
[0030] The sidewalls of the heating tank 11 are sequentially coated with a heat-conducting layer and an antibacterial layer. The heat-conducting layer can be a graphene coating, and the antibacterial layer can be a zinc oxide coating or a titanium dioxide coating. The heat-conducting layer effectively transfers the heat generated by the heating element to the hand, thereby increasing the heating speed and reducing heat loss during the heating process. The antibacterial layer improves the overall antibacterial performance, thus meeting the needs of the medical field.
[0031] Please refer to Figure 4 As shown, the heating groove 11 includes a palm heating area 111 and multiple finger heating areas 112, the shape of which can be the same as the shape of a person's five fingers. An elastic element 22 can be fixed to the base 1 by multiple fixing members, which divide the elastic element 22 into a cavity 1 and multiple cavities 2 connected to the cavity 1. Cavity 1 is aligned with the palm heating area 111, and each cavity 2 is aligned with each finger heating area 112. The cross-section of cavity 2 can be an inverted U-shaped structure, forming a ring structure between cavity 2 and the finger heating area 112, thus facilitating the wrapping of the finger after insertion, thereby preventing heat loss during the heating process and improving its heating effect. Combined with the heating element, it can effectively and quickly heat various parts of the hand. Furthermore, in this solution, each heating unit is independently controlled by a controller, so different areas of the hand can be heated in different zones during actual use. This zoned heating method can target different areas of the hand, achieving the purpose of heating the hand without wasting energy. In addition, this zoned heating method can provide localized heating to specific areas of the hand (such as the fingertips and knuckles) of people with poor peripheral circulation, thereby improving the overall practicality of the hand heating device.
[0032] In this solution, a high-precision miniature temperature sensor, such as an NTC thermistor, can be used as the temperature sensor, which can provide real-time feedback on the temperature of a localized area of the hand. The heating element can be a heating film or a heating wire.
[0033] The elastic element 22 can be made of medical-grade flexible materials, such as silver ion fiber fabric, hemp fiber fabric, or graphene / silver composite fiber fabric. Flexible electrothermal materials such as carbon fiber heating wires can also be integrated within the elastic element 22. The carbon fiber heating wires can be woven into the flexible material and divided into multiple independent heating zones within the elastic element 22. In actual use, the power supply can also provide power to the carbon fiber heating wires, and the controller can control the power supply to turn the carbon fiber heating wires on and off. In actual use, when the elastic element 22 is wrapped around the hand, the controller can activate each carbon fiber heating wire, enabling the carbon fiber heating wires within the elastic element 22 to heat the back of the hand, thereby further improving heating efficiency. An insulation layer can also be coated on the side of the elastic element 22 facing the heating groove 11. The insulation layer material can be a polyurethane elastomer composite material. Coating with an insulation layer can lock in the temperature within the heating cavity 24, further improving the overall heating effect.
[0034] in, Figure 4 The diagram in the middle shows the structure of the mounting slot 12 on the base when the door is not installed. Please refer to it. Figure 4 The base 1 also has a mounting slot 12, which is located below the heating tank 11 and is separated from the heating tank 11 by a flexible fabric layer. The mounting slot 12 may have an openable door, which allows the mounting slot 12 to be closed or opened. The flexible fabric can be a common medical antibacterial fabric in the prior art, such as silver ion fiber fabric, hemp fiber fabric, or graphene / silver composite fiber fabric. A massage component is installed in the mounting slot 12 to massage the hand placed in the heating tank 11. In this solution, by setting the massage component below the heating tank 11, the hand can be heated and massaged at the same time. The massage component can be a common ball bearing massager in the prior art, which can be directly and integrally installed in the mounting slot 12 and controlled to start or stop by a controller. This solution incorporates a massage component that heats and massages the hand simultaneously, promoting blood circulation. The massage component also allows surgeons to massage their hands after surgery, alleviating finger spasms and fatigue caused by prolonged fine motor operations, thus enhancing the overall practicality of the medical hand heating device.
[0035] The base 1 may also be equipped with a mounting component (not shown in the figure), which is used to fix the medical hand heating device to the base 1. The mounting component may be a rope with a buckle, a magnetic component, or other existing common fixing devices that can fix the base 1. By setting the mounting component, the medical hand heating device can be fixed, improving its stability during use.
[0036] The medical hand heating device may also include an external terminal. The controller is equipped with a data communication module that communicates with the external terminal. The data communication module is used to transmit the data collected by the controller to the external terminal. The external terminal is also equipped with a display that displays the data collected by the controller, so that people can intuitively understand the internal situation of the medical hand heating device.
[0037] The medical hand heating device can also be equipped with an alarm. The alarm will sound when the power supply is below 10% or when the temperature of any temperature sensor exceeds the safety threshold of 45°C. At the same time, the controller will immediately cut off the circuit of the heating unit. This feature can also prevent burns caused by excessive heating and improve the safety of the entire medical hand heating device during use.
[0038] Example 2 This embodiment provides a control method for a medical heating device based on the medical hand heating device provided in Embodiment 1. The method includes the following steps: acquiring the temperature of each temperature sensor and making the following judgment: if the temperature of a certain temperature sensor is less than a set temperature threshold one, then the heating element corresponding to that temperature sensor is activated; and if the temperature of the temperature sensor is higher than a temperature threshold three, the corresponding heating element is deactivated. This setting enables zoned heating of different parts of the hand, effectively solving the problem of inability to achieve zoned heating in existing technologies. Furthermore, by setting temperature threshold one and temperature threshold three, the heating temperature range of the heating element can be effectively controlled, effectively solving the problem of easy burns to the hand due to excessively high heating temperatures in existing technologies.
[0039] The system acquires the number of temperature sensors whose temperatures are below a set temperature threshold, and activates the blower when the number of temperature sensors whose temperatures are below the set temperature threshold exceeds half the total number of temperature sensors. This operation enables the coordinated use of elastic wrapping and heating elements to improve overall heating efficiency when the overall hand temperature is low.
[0040] The system acquires the number of temperature sensors whose temperatures exceed a set temperature threshold of two, and shuts off the blower when the number of temperature sensors whose temperatures exceed the set temperature threshold of two is greater than half of the total number of temperature sensors. This setting allows the heating rate to be slowed down after the hand has been heated and the elastic element has been removed, preventing burns caused by excessively rapid heating.
[0041] Example 3 This embodiment provides a computer program product, which includes a computer program. When the computer program is executed by a processor, it implements the control method of the medical heating device as described in Embodiment 2, thereby achieving zoned heating of different areas of the hand.
