Description

Stretcher trolley

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a stretcher trolley.

Background

The medical stretcher trolley is generally composed of a stretcher trolley body (composed of a stainless steel or aluminum alloy main frame), casters, a detachable stretcher and other main parts and accessories (such as a brake, a lifting infusion frame and the like). The shape of the stretcher is required to be neat, and the surface of the stretcher is free from defects such as sharp edges, burrs, scars and the like. The cooperation of the stretcher vehicle requires that the stretcher vehicle and the stretcher should be convenient to assemble and disassemble. After the stretcher is assembled with the stretcher, the stretcher should be firmly fixed and not loosened. In addition, ambulance stretchers, which also have casters, are required to be able to transfer and transport patients on flat ground and to be pushed or lifted directly onto the ambulance, and to be able to fix the stretcher onto the ambulance.

The stretcher trolley in the prior art has various types and different structures. But the structure generally has the problem of unidirectional operation. I.e., the vehicle body must be adjusted to the longitudinal direction of the vehicle body structure and pushed from the rear to the front when pushing the vehicle body. The emergency rescue device is not flexible and convenient to use, and is not beneficial to carrying and rescuing critical patients in emergency. In addition, because the stretcher is fixedly placed in the longitudinal direction of the stretcher body structure, when the stretcher needs to be pushed or lifted on an ambulance, the stretcher body structure also needs to be longitudinally adjusted to be opposite to the ambulance and then the door is opened, and certain inconvenience is brought to operation.

Disclosure of Invention

The slide way, the slip ring and the stretcher seat can be locked by a locking device. The stretcher is arranged on the stretcher seat.

Further, the outer side of the vehicle body is connected with an annular push handle through a connecting rod.

Further, the lower side of the slideway is connected with a plurality of vertical rods, the bottoms of the vertical rods are connected with casters, and reinforcing rings are arranged between the vertical rods; the casters are provided with braking devices which are operable on the periphery of the vehicle body.

Further, a fixed plate is arranged at the bottom of the stretcher seat and is fixedly connected to the upper part of the slip ring; the upper part of the fixed plate is fixedly connected with two stretcher seat plates, and the stretcher is placed on the stretcher seat plates.

Further, the locking device comprises a fixed hinge support and a clamping groove which are connected to the outer side of the stretcher seat plate; the fixed hinge support is connected with a support rod through a movable hinge, and the support rod can be clamped in the clamping groove; the outer end of the supporting rod is fixedly connected with a locking ring and a handle; the slideway and the slip ring are respectively provided with an arc slideway lock hole and a slip ring lock hole which can be mutually communicated; the locking ring can be inserted into the through circular arc-shaped slideway lock hole and the slip ring lock hole in a rotating way through the movable hinge.

The beneficial effects of adopting above-mentioned scheme are: the stretcher trolley comprises a trolley body and a stretcher, wherein a circular slideway is arranged at the upper part of the trolley body, a sliding ring is arranged at the upper part of the slideway, and the upper part of the sliding ring is fixedly connected with a stretcher seat. The slide way, the slip ring and the stretcher seat can be locked by a locking device. The stretcher is arranged on the stretcher seat. Solves the problem that the stretcher trolley structure in the prior art generally has unidirectional operation. The stretcher trolley can be pushed in multiple directions, so that the stretcher trolley is flexible and convenient to use. The emergency treatment device is beneficial to the transportation and rescue of critical patients. When the stretcher is required to be pushed or lifted to be placed on the ambulance, the direction of the stretcher can be flexibly rotated and adjusted to be opposite to the back door of the ambulance according to the moving requirement of the stretcher after the vehicle body is braked. Brings great convenience to operation.
