Multifunctional wounded and sick person conveying device and using method thereof

Abstract

The invention relates to a multifunctional wounded and sick person conveying device and a using method thereof. An upper plate, a middle plate and a lower plate of the device are sequentially articulated. The upper ends of a front support leg and a rear support leg of a bracket are fixedly connected to the lower plate and the upper plate respectively; the front support leg and the rear support leg are provided with side connecting rods which are articulated; a transverse rod is fixedly connected with the two side connecting rods; slideways are arranged on a left slide frame and a right slide frame of the lower plate, and both ends of a slide rod are embedded into the slideways; a front traveling wheel is installed at the front end of the lower plate; a motor is fixedly installed at the bottom of the middle plate, and a swinging rod installed on the motor is articulated with the slide rod by a pull rod; a rear wheel rod, the bottom end of which is provided with a rear traveling wheel, is articulated to the front side of the middle plate; and a rear wheel pull rod is articulated with the slide rod and the rear wheel rod. In the using method, the three plates are parallel, the swinging rod trends to the front, the rear traveling wheel is raised, and the bracket supports the three plates to form a stretcher. The swinging rod is swung to be vertical, and the rear traveling wheel is supported to form a cart. The swinging rod is backwards swung, the upper plate upwards rotates to form a backrest, the lower plate is downwards folded, and the front traveling wheel and the rear traveling wheel support the three plates to form a wheel chair. The invention realizes the reversible deformation in a state of the stretcher, the cart and the wheel chair, is suitable for different road conditions to convey wounded and sick persons in a rapid and labor-saving way, and has convenient operation.

Description

(1) Technical field [0001] The invention relates to a device for transporting the wounded or patients during first aid, in particular to a multi-functional transporting device for the wounded and sick which can be transformed into a stretcher, cart or wheelchair and its application method. (2) Background technology [0002] On the battlefield or in emergency rescue situations, stretchers are an indispensable tool for transporting the wounded or sick. Existing stretchers or simple folding stretchers on the market can only be carried by two people to walk the wounded and sick, and the physical exertion of transporting personnel is large. In addition, when running into narrow turns, it is more difficult to carry. [0003] In order to facilitate transportation, some multi-purpose transport devices for the wounded and sick have appeared, such as stretchers equipped with walking wheels, some of which also have a deformation function, which can allow patients to lie or lean on the...

AI Technical Summary

Problems solved by technology

However, in order to achieve multi-function and multi-purpose, the existing transport devices for the sick and the sick have complex structures and heavy weights, which affect their use as stretchers; and the deformation can only be controlled manually, and it is difficult to deform when the sick and wounded are lying on the stretcher

The other four walking wheels are used for support and cannot be stowed away. They are suitable for use on flat road conditions, but difficult to use on poor road conditions.
