Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a wrist temperature measuring device for magnetic resonance imaging. Background Technology

[0002] Magnetic Resonance (MR) is a medical examination method that uses the magnetic resonance phenomenon to generate magnetic resonance signals to form images. MR examinations are non-radioactive and safer than X-rays and CT scans; however, magnetic metal objects can generate heat during MR examinations, potentially causing burns to the patient. Therefore, temperature monitoring of the areas containing metal objects is necessary.

[0003] In existing technologies, temperature probes are often fixed to the area to be measured, and the temperature signal is input to the magnetic resonance instrument through a circuit. This has the following technical problems: 1. It is inconvenient to wear. The temperature probe needs to be glued to the area to be measured every time it is used. If it is not glued tightly, it may lead to inaccurate temperature detection. If it is glued too loosely, the temperature probe may fall off. 2. The circuit connection is inconvenient. The temperature probe is connected to the magnetic resonance instrument through a circuit. The connection is troublesome and the circuit poses a safety hazard of tripping over people.

Detailed Implementation

[0021] The present invention will now be described in further detail.

[0022] A wrist-based temperature measurement device for magnetic resonance imaging (MRI) includes a temperature measurement component 1 with an external anti-magnetic device. The component comprises a wristband 3, a temperature sensor 6, a processor 9, a first wireless communication module, and a battery. The component is battery-powered. The temperature sensor and the first wireless communication module are electrically connected to the processor. The temperature sensor, mounted on the inside of the wristband, detects the temperature of the subject's wrist and sends the temperature information to the processor. The processor processes the temperature information from the sensor and transmits it to an external device via the first wireless communication module. This device outputs temperature information via the first wireless communication module, eliminating the need for a long wire to connect the temperature measurement component to the MRI machine, making it easy to wear and use.

[0023] The wristband features a quick-release mechanism, which is a Velcro strap.

[0024] There are multiple temperature sensors arranged along the length of the wristband.

[0025] The temperature measurement component also includes a cooling pad 7, which is fitted to the inside of the wristband. The cooling pad has multiple clearance holes 5, within which the temperature sensor is located. These clearance holes allow the temperature sensor to directly contact the wrist. The cooling pad helps to lower the temperature during the magnetic resonance imaging (MRI) examination, reducing the risk of burns to the patient's wrist. The clearance holes ensure direct contact between the temperature sensor and the wrist, resulting in more accurate temperature readings. In this embodiment, the cooling pad is secured to the wristband with Velcro.

[0026] The cooling pad incorporates phase change materials. Compared to ordinary thermally conductive materials, cooling pads made from phase change materials can dissipate heat more quickly, improving the safety of the magnetic resonance imaging (MRI) examination process.

[0027] It also includes a monitoring component 2, which is separately configured from the temperature measurement component. The monitoring component includes a second wireless communication module, an alarm 11, and a power supply. The second wireless communication module is electrically connected to the alarm and is used to communicate with the first wireless communication module. The power supply provides power to the monitoring component. In this embodiment, the power supply can be a battery or an external power source.

[0028] During an MRI scan, the patient undergoes the examination in the examination room, while medical staff control the MRI machine from the control room. The temperature measurement and monitoring components are separate, allowing medical staff in the control room to obtain the patient's wrist temperature information. This device uses a second wireless communication module in the monitoring component to receive the patient's wrist temperature information, eliminating the need to input the temperature information into the MRI machine. Therefore, there are no compatibility issues to consider, making it easy to use.

[0029] The battery used is a removable lithium battery. If the battery in the temperature sensing component is found to be low, the battery can be replaced by removing the low-charge battery and replacing it with a charged battery.

[0030] The monitoring component also includes a charging dock 12, to which the lithium battery is fitted. The battery removed from the temperature sensing component can be charged via the monitoring component's charging dock.

[0031] The monitoring component also includes a display screen 10, which is electrically connected to a second wireless communication module. The display screen shows temperature information detected by the temperature sensor. During an MRI scan, the settings of the MRI equipment can be adjusted by observing the temperature information on the display screen to prevent burns to the patient.

[0032] Both the first and second wireless communication modules are Bluetooth modules.

[0033] This device can be used for magnetic resonance imaging (MRI) examinations and features advantages such as wrist temperature measurement, wrist cooling, high-temperature alarm, visual temperature information, and reusable battery. During use, the patient secures the wristband to their wrist with Velcro. A cooling pad on the inside of the wristband helps lower the wrist temperature, while a temperature sensor inside the wristband monitors the patient's wrist temperature in real time. The temperature data detected by the sensor is processed by a processor and transmitted to the monitoring component via Bluetooth. The measured temperature is then displayed on the screen. If the patient's wrist temperature is too high, an alarm in the monitoring component will sound to alert medical personnel.

[0034] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
