Description

A handheld ultrasound system with temperature control function Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a handheld ultrasound system with a temperature control function. Background Art

[0002] Compared to traditional wired ultrasound probes, wireless ultrasound probes are more portable, smaller, and more convenient for users to perform ultrasound examinations, making them a growing option for medical ultrasound examinations. However, wireless ultrasound probes generate heat during operation. The higher the probe's performance, the higher its power consumption and the greater the heat generated. Excessive heat not only affects the operation of the probe's internal electronic components but also easily causes the probe housing to heat up, causing significant discomfort to the user. Due to heat dissipation issues, some wireless ultrasound probes can only maintain power consumption around 2W, resulting in poor performance and an inability to meet the increasingly complex demands of ultrasound testing. Other wireless ultrasound probes utilize full or partial metal housings, increasing the housing area to dissipate heat, thereby improving performance and reducing power consumption to over 4W. However, these probes are bulky, which conflicts with the miniaturization requirements of wireless ultrasound probes. Wireless ultrasound probes are small and compact, resulting in limited heat dissipation space and high circuit power consumption, which can lead to increased housing temperature and shortened device life. To address these technical issues, the following technical approaches have been adopted: 1. Adding heat dissipation holes to the housing. Disadvantages: (1) There are gaps, which are not dustproof or waterproof, and are difficult to clean; (2) If the opening is small, the heat dissipation effect is poor, and if the opening is large, the integrity and stability of the whole machine will be affected. 2. Built-in fan and increased heat dissipation holes for heat dissipation. Disadvantages: (1) Noisy; (2) The fan is easy to break. 3. Solid-solid energy storage material is injected into the casing. Disadvantages: (1) Inconvenient to produce and maintain; (2) Due to the limited size of the machine, it is impossible to use too much energy storage material, so after a period of time, the temperature of the machine casing will rise rapidly.

The solid-liquid energy storage material and the motherboard 11 form a heat transfer structure to absorb heat emitted by the motherboard 11 and convert it into internal energy. When the solid-liquid energy storage material absorbs a certain amount of heat, the heat-absorbing solid-liquid energy storage material is separated from the motherboard 11 by replacing the battery module 7, thereby removing the heat.
