In crossing and landing operations, how to safely and efficiently transport the wounded beachhead onto landing craft, and then go to the rear of the successful treatment is a further problem facing the health service work.

As we all know, from the beach to the landing craft is usually 5m ~ 30m, water depth generally about the distance of 1.3m ~ 2.5m, and even deeper, while the sea waves are big, smooth ordinary floating equipment difficult to control. And I found that the most commonly used tool is moving stretcher. Generally do not have floating stretcher function, and general self-floating anti-wave equipment performance is poor. If you re-create a new floating stretcher, will need to spend a lot of manpower and material resources, the author to be modified on the basis of existing stretcher, can be turned into a stretcher landing operations can be adapted for use. Analysis is now as follows:

1 breakwater portable folding stretcher Features

(1) low price: just a small modification to the original stretcher on the basis of costs only 30 yuan.

(2) Anti-waves, good stability, buoyancy: The stretcher contact with seawater area from 1.8mx0.5m = 0.9m², increased 1.8mx1.5m = 2.7m², wounded floating on the stretcher when the sea is not easy to turn over the sea.

(3) create a simple, easy to operate: general repair unit can be produced, the stretcher Expand only about 25s, people would not need special training to use.

2 Materials

materials needed:

(1) Retractable Collar (trumpet) 4; water pipes under the clip (trumpet) 4; 8 sets of deduction.

(2) rigid stainless steel pipe: diameter 2.5cm, length 55cm, 2-gen; diameter 2.2cm, length 55cm, 4-gen; diameter 1.8cm, length 55cm, 4 roots.

(3) Individual lifebuoy 4.

3 Production Method

(1) The retractable ferrule welded to the lower pipe clamps, angle of 90 °.

(2) Then take the tube clamp on a stretcher in the middle.

(3) stainless steel tube sets by size each other well, the same principle as the automatic umbrella rod contraction.

(4) stainless steel tube were then set in scalable ferrule, while the man with life buoy jacket buckle fixed at both ends.

(5) after the completion of fixed stretcher in turn can make use of floating stretcher.
