Description

Technical Field

[0001] The utility model relates to a trailer, in particular to a comprehensive support trailer for a field operation vehicle, belonging to the technical field of field medical equipment. Background Art

[0002] In modern warfare, the variety of war forms, the number of casualties, injuries, time, and region are all extremely uncertain. How to carry out surgical treatment more flexibly, quickly, and effectively is particularly critical. Due to the limitations of the field environment and the equipment carried, the field surgical vehicles and supporting deployment plans currently distributed by the military have basically achieved the level of rapid construction and operation of operating rooms under field conditions, but in the implementation of actual combat exercises, they still show the characteristics of "time-consuming and labor-intensive": (such as the medical staff's washing, disinfection, changing clothes and other materials must be unloaded from the truck and deployed in the preparation area tent). This restricts the mobility of the field medical team and the surgical team and the timeliness of the operation.

[0003] In recent years, research has only made optimizations in method flow and module construction. For example, a medical surgical vehicle disclosed by announcement number CN211493794U is only equipped with medical equipment in the vehicle, which can perform ordinary surgical operations on a daily basis and reduce the pressure on surrounding hospitals. A field surgical vehicle disclosed by announcement number CN117159286A has a double-sided expansion cabin with a folded state and an unfolded state, realizing the change of the surgical operation area from the surgical vehicle to the surgical cabin, from the operation on the vehicle to the operation under the vehicle, integrating the surgical equipment unit and the efficacy guarantee unit. A medical surgical vehicle disclosed by announcement number CN217835469U can perform surgical treatment on the patient during the transfer, so as to timely control the patient's condition, but the existing technology does not fundamentally solve the problem of time-consuming and laborious mobile deployment of the surgical team of the field medical team; in addition, especially in the extremely cold temperature environment in northern my country in winter, the carried supporting medicines are easy to freeze, which affects the safety and timeliness of the medicines, and thus seriously affects the timeliness of the operation.
