AI Technical Summary
The existing portable medical imaging detectors have reduced performance or damaged due to problems caused by high pressure and thermal energy during long-term work, and cannot work continuously for a long time, which limits their application in field first aid and disaster rescue.

The insulating oil expands by heat when the X-ray tube works and overflows to the liquid-swelling soft bubbles. The soft bubbles buffer the expansion of the insulating oil, thereby avoiding damage to the X-ray tube and high-pressure packs and achieving long-term stable work.
Through the design of the liquid shell and liquid-swelling soft bubble, the problem of X-ray tube damage due to thermal expansion is solved, and the long-term work of the portable medical image detector is realized, which improves the detection efficiency and practicality.

Abstract
Description
Technical Field
[0001] The invention relates to a medical image detection technology, in particular to a portable medical image detection instrument. Background Art
[0002] With the continuous advancement of medical technology and the growing demand for medical services, medical imaging detection equipment plays an increasingly important role in clinical diagnosis and disaster relief. Traditional indoor medical imaging detectors are usually large and heavy and need to be installed in fixed rooms, which limits their application in special environments such as field emergency and disaster relief. In addition, traditional equipment has poor mobility and flexibility, making it difficult to meet the needs of rapid response and timely diagnosis. In addition, the radiation intensity of the equipment is high, requiring special protective measures, which increases the difficulty and cost of use.
[0003] Portable medical imaging detectors are small and light in size, easy to carry and move, and can quickly reach any place where they are needed to meet the needs of special environments such as field first aid and disaster relief. They are suitable for various departments within the hospital and can also play a role in special occasions such as field first aid and disaster relief, which can improve the flexibility of medical services and diagnostic efficiency.
[0004] However, since the core component X-ray tube has special high voltage when working, heat energy is generated when working for a long time, which leads to the performance degradation of the X-ray tube and even damage to the X-ray tube. The cooling device of the prior art can only provide short-term cooling and heat dissipation, which leads to the X-ray tube cannot work continuously for a long time. If it works for a long time, the expansion of the coolant and the expansion of the X-ray tube will squeeze each other and damage the X-ray tube and the shielding layer. Therefore, in order to avoid damage to the X-ray tube, the prior art uses it for a period of time and then pauses for a period of time before continuing to use it. It cannot work continuously for a long time, so that the detection efficiency of the portable medical image detector is low and the practicality is not high. Especially in the field rescue and disaster relief detection, the detection speed and efficiency cannot keep up with the needs of disaster relief. Therefore, there is a great need for a portable medical image detector that can be used continuously for a long time. Summary of the invention
