Description

Medical and sanitary tent capable of being rapidly unfolded

Technical Field

The invention relates to a field rescue facility, in particular to a medical and sanitary tent capable of being unfolded quickly.

Background

At present, the condition of an injury and illness occurring on the sea is mainly to send the injured and sick person to land for treatment, and ship transportation or air transportation is selected according to the condition of the illness, and the condition is not generally treated for a long time. The reason is that the sick and wounded are not fulminantly produced on the sea on weekdays, the benefit of establishing the special offshore treatment platform is not good, and the requirement in the civil field is low. For offshore military operations, the occurrence of sick and wounded has obvious batch and complexity, critical severe cases requiring urgent internal and external treatment are more, and the sick and wounded cannot be sent for treatment in a short time, so that a maritime sick and wounded treatment platform is developed, and most of the platforms represent various hospital ships. The specialized hospital ship is usually low in service reserve due to high cost, meanwhile, the standing construction time of the domestic hospital ship in all countries in the world is generally earlier, the accommodation capacity cannot meet the requirement of treating a large number of wounded persons on the sea, and other hospital ships such as modular hospital ships (additionally provided with medical containers and expansion modules, usually civil ships) are required to be supplemented and extended when participating in military operations.

The modularized hospital ship is easy to aim at due to the defects of large volume, slow movement, weak protection, less cooperative training and the like. The proposal also brings about the key contradiction of planning and using the internal space of the military offshore platform, because the modular hospital ship basically adopts sanitary container modules, and additionally assembled containers and modules need to be pre-arranged on the offshore platform in advance, the internal space and carrying capacity of the ship can be occupied to different degrees, and the occupation is irreversible, so that the modification of part of military platforms into the modular hospital ship only has theoretical possibility, and the difficulty is higher when the modification is realized.

The medical operation tent is usually applied to the field or under the emergency condition, plays an important role in the emergency relief and even the military operation, solves the emergency treatment requirements of internal and external departments of a batch of sick and wounded under the extreme condition, integrates the experiences obtained by the major war and the non-war military operation (such as new crown epidemic situation and earthquake relief) of a field medical treatment place, and is more critical to timely develop the medical treatment and treatment power of the tent at one line, so that the research on fire and heat in the field of the current medical treatment and health tent is basically blank in the independent research on the marine tent and the related research on the marine reformation of the land-based tent in view of the essential difference of the marine environment, and has lower referential property and mainly has the following reasons:

1. the tent has high space requirement, the occupied area of the field medical tent used at home and abroad at present is not less than 45 square meters, the construction cost and the operation benefit of ships and other offshore platforms are considered, and most offshore platforms do not support the space condition for the expansion of the tent;

2. the requirement on the operation environment is high, the requirement on the corrosion resistance of tent materials and instruments and equipment is high in the marine high-salt high-humidity environment, and a large amount of secondary pollution pathogenic microorganisms existing in the high-humidity closed environment in the cabin are easy to cause secondary infection of wounds, so that the requirements on isolation and clean conditions for marine operations are high;

3. the sea condition adaptation requirement of the medical apparatus is high, the ship sways, not only causes little challenge to the physical and mental quality of an operation team, but also puts higher requirements on the fixation of operation related apparatus and equipment, and besides the tent needs to be improved in design, related operation equipment needs to be adapted to ships and sea conditions;

4. tent support is fixed to require differently, and land-based tent mainly leans on the ground nail external fixation except that self skeleton texture provides the support, and marine space is limited and narrower usually, and the internal pipeline is complicated and complicated, can't reach the ground nail fixed condition, and this is also not little challenge to the selection of tent fixed mode. Therefore, no matter a novel marine operation tent is independently designed or the conversion from a land-based operation tent to a marine operation tent is realized, the design is improved or even redesigned from the aspects of materials, structures and the like.

By combining the situations and the current development situation of the current marine medical service team, the marine medical and health tent which is suitable for the offshore platform (dual-purpose for military and civil use), can be rapidly unfolded, has high space utilization rate, good sterile conditions and stability, can greatly improve the capability of handling the marine injuries and has great practical significance is researched and designed.
