AI Technical Summary

Problems solved by technology

However, this method has high requirements on the performance of the car, and due to the large number of equipment in the entire shelter system and the heavy weight, the car appears cumbersome and has poor maneuverability when moving.
On the other hand, in order to meet the needs of flexible and mobile use, the body length and load capacity of the carrying vehicle must be limited, and this limitation makes the vehicle unable to carry the weight of the entire fixed inspection room, so this is a problem in the prior art. a pair of contradictions
On the other hand, it can be considered to reduce the number of equipment in the cabin. However, a smaller number of equipment will reduce the medical service capacity of the entire medical shelter, that is, the medical service capacity will become low and cannot meet the needs of field medical treatment needs

Embodiment 1

[0030] see figure 1 , which shows the vehicle status of the medical shelter used in the field environment according to the preferred embodiment of the present invention. see Figure 4 , which shows a schematic diagram of the unfolded internal layout of the medical shelter for field environments according to a preferred embodiment of the present invention. The medical shelter is a large panel cabin with a flap type double expansion structure. The inside of the shelter includes a CT control room 31 and a CT scanning room. The CT control room is located at the front of the shelter, and a CT device is installed in the CT scanning room. 34.

[0031] In order to enable the medical shelter to be used in the field, the present invention proposes a radiation graded protection method for the medical shelter in the field environment. The method includes the following steps: 1) Obtain the scattered radiation dose distribution curve of the CT device 34, see figure 2 , which shows a CT...

Embodiment 2

[0047] Another preferred embodiment of the present invention will be described in more detail below in order to more fully demonstrate the above-mentioned advantages and beneficial effects of the present invention.

[0048] Such as Figure 4 As shown, the internal layout of the CT shelter in the unfolded state can be further set as follows: the CT control room 31 is located at the front of the whole cabin (along the forward direction of transportation), the CT scanning room is located at the rear of the whole cabin, and a scanning bed 33 and a CT device 34 are arranged. , CT damping bracket 35, cabin partition 37, control room partition 38 and control room observation window 39. For example, the internal dimensions of the CT shelter in expanded state are 3900(L)x5800(W)x1950(H)(mm). It can be understood that these specific structures and parameters can be adjusted, and should not be regarded as any limitation to the present invention. Preferably, regarding the structure of t...

Abstract

A radiation grading protection method of a medical shelter for a field environment includes the steps: acquiring a scattered radiation dose distribution curve of a CT (computerized tomography) device; dividing the shelter into a plurality of sub-regions; determining the thickness H of a lead plate needed to be arranged on the inner wall of each sub-region of the shelter according to a particular formula; and arranging the lead plate with the thickness H on the inner wall of each sub-region of the shelter as a shield, wherein the lead plates arranged on the inner wall of the shelter are different in thickness. By the radiation grading protection method of the medical shelter for the field environment, the overall weight of the medical shelter is greatly reduced on the premise of safety radiation protection, the medical service capacity of the medical shelter is high, maneuverability is fine, and cost is reduced.

Description

technical field [0001] The invention relates to a radiation classification protection method for a medical shelter used in the field environment, in particular to a radiation classification protection method for a vehicle-mounted medical shelter. More specifically, it relates to a conformal radiation classification protection method for a CT (Computed Tomography, computerized tomography imaging) workplace working in a shelter. Background technique [0002] CT equipment is a computer-aided imaging equipment that uses X-rays as the transmission energy of human body tomography. It has become a popular medical equipment for inspection and diagnosis in hospitals. Surgery provides the most valuable instructional information. my country is a country with frequent natural disasters. In recent years, natural disasters such as earthquakes, floods, and mudslides have occurred frequently. The field medical clinics and shelter hospital systems have played an important role in earthquake...
