specific Embodiment 1

[0063] Specific embodiment 1: one-person consignment mode of towed stretcher

[0064] In the case of non-soft ground, one-person consignment mode of towed stretcher can be carried out, such as Figure 11 shown.

[0065] Since one end of the towing stretcher is provided with two moving wheel assemblies (8), when hauling the wounded, the moving wheel assembly can be used as a supporting end, which reduces the force on the hauling personnel, reduces physical exertion, and speeds up the hauling speed. Rescue buys time. Moving wheel assembly (8) comprises wheel frame (81) and moving wheel (82), is provided with space between described moving wheel and wheel frame; Described moving wheel (82) adopts two steel core rubber wheels, and its wheel The diameter is 76mm. The moving wheel assembly is arranged on the end face of the stretcher, which simplifies the structural size and reduces the weight of the moving wheel assembly. There is enough space between the tread of the moving whe...

specific Embodiment 2

[0068] Specific embodiment 2: Two people carry mode of towing type stretcher

[0069] In the two-person lifting mode of the towed stretcher, two people lift the front and rear ends of the towed stretcher respectively. Tie the shoulder straps to the safety fixing rings of the front support frame and the rear support frame respectively, and at the same time put the shoulder straps on the shoulders of the lifter. Rubber handles are installed on the stretcher longitudinal bars at both ends of the stretcher, which have the effects of anti-slip, heat insulation, and cushioning, and improve the comfort of the hands of the carriers.

[0070] In addition, in the two-person lifting mode of the towed stretcher, attention should be paid to the balance of the stretcher.

specific Embodiment 3

[0071] Specific embodiment 3: full-body hoisting mode on towed stretcher

[0072] In the full-body lifting mode of the towed stretcher, if Figure 12 As shown, when the tow sling is lifting the whole body, the braided belt of the stretcher is lifted. The two ends of the tow sling are fixed on the safety rings of the front and rear support frames by suspension rings 91, and the middle part of the tow sling is sewed with a limit ring 92 to avoid the change of the lifting position and cause the stretcher center of gravity to be unstable. Shoulder straps are soft straps that hang over the shoulders on both sides of the porter during hauling and lifting. It can not only reduce the fatigue of the arm, but also prevent the carrier from slipping, causing the danger of the stretcher and the wounded rollover.

Abstract

A towed stretcher comprises a front supporting frame, a front self-locking joint, a middle supporting frame, a rear self-locking joint, supporting fabric, a safety fixing ring, a rear supporting frameand a moving wheel assembly. The front supporting frame is connected with the middle support frame through the front self-locking joint; the rear support frame is connected to the middle support frame through the rear self-locking joint; the moving wheel assembly is installed at the tail end of the rear supporting frame. A lifting belt comprises a binding belt, a main lifting belt, a chest auxiliary belt, a chest auxiliary belt lock catch, a waist fixing belt and a waist fixing belt lock catch. A wounded person lifting appliance comprises the towed stretcher and / or the lifting belt. The towedstretcher and the wounded lifting appliance have multiple functions of wounded vertical lifting, helicopter lifting rescue, manual lifting and the like, the wounded person lifting appliance is composed of a towed stretcher body and a lifting belt, and the towed stretcher body is used for towed lifting and lifting of the wounded; the lifting belt is used for tank wounded person cabin-exiting lifting, underground rescue, narrow gap rescue and the like.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, relates to a towed stretcher and a sling for the wounded. Background technique [0002] Stretchers are widely used in war or disaster rescue activities as the most basic rescue tool for transporting wounded and sick people. However, the existing stretchers have a single function and are difficult to meet the multiple requirements of rescue in different situations. In addition, the spreader is also widely used in the rescue process. [0003] But conventional ordinary rescue spreader and stretcher function are all relatively single, do not possess the integrated function of lifting and stretcher. Contents of the invention [0004] (1) Technical issues [0005] Therefore, how to solve the problem that the conventional ordinary rescue spreader and stretcher in the prior art have single functions and do not have the comprehensive function of lifting and stretcher ...
