Abstract

The utility model discloses a go up and down type stretcher with wheels, comprising a cushion, a stretcher, guide wheels, a transfusion stand, a telescopic locking supporting bar, a bracket, supporting rods, an upper strut beam, a lower strut beam, a connecting rod, a rocking handle, road wheels, an inner coil and a screw rod. The utility model is characterized in that the supporting rods are supported when the screw rod in the inner coil screws outwards and the supporting rods retract when the screw rod screws inwards. The supporting rods can also be supported when the screw rod in the inner coil screws inwards and the supporting rods can retract when the screw rod screws outwards with the position of the supporting rods changing. The cushion on the stretcher can be pulled, and used for lifting patients as well. The stretcher has three segments, and the front and the back two segments are mobile type.

Description

A kind of lift stretcher

This utility model relates to a kind of stretcher that can lifting.

Stretcher is used to transport the sick and wounded, but the stretcher that uses at present lacks vibrationproof, lacks elevating function, lacks drip stand, and patient's ambulance up and down needs four or five people to carry on to move down, and stair activity is also inconvenient.

The purpose of this utility model is the deficiency that will overcome above-mentioned prior art, and provide a kind of can be as required lifting arbitrarily, vibrationproof, drip stand, the stretcher of the stair activity of especially convenient upper and lower ambulance be equipped with.

The purpose of this utility model can take following measure to reach:

A kind of lift stretcher, comprise cushion, stretcher, directive wheel, drip stand, retractility lock support bar, carriage, strut, go up strutbeam, following strutbeam, connecting rod, rocking handle, road wheel, interior screwed pipe, screw rod, road wheel is connected with stretcher by the bridge-type lifter before and after it is characterized in that.

Because this utility model has been taked abovementioned technology, making it to contrast prior art has following advantage:

1, easy to use:

Patient is ambulance up and down, and go downstairs and need not lift, and operating-table or sick bed up and down easily.

2, simple in structure:

Adopt the bridge-type lifting structure, simple and practical, stability and self-locking performance are good, and it is low to have minimum point, the advantage that pure rise is big.

The drawing of accompanying drawing is described as follows:

The utility model is described in further detail below in conjunction with accompanying drawing:

This utility model comprises the ring that has available hands to grab on cushion (1), the cushion (1), can lift or drag cushion.Stretcher (2) is made up of framework and canvas or nylon cloth or plastic wire bed surface.Front end at stretcher (2) has a pair of directive wheel (3), and directive wheel (3) is mainly used in ambulance up and down.Two retractility lock support bars (4) are equipped with in stretcher (2) rear end, and retractility lock support bar (4) is socketed to form by inside and outside two bars, and its length can regulate and lock, and road wheel is equipped with in the lower end.Stretcher (2) is gone up and is equipped with drip stand ready for using (14), props up during use.Carriage (5) is the connector of stretcher (2) and strut (6).Strut (6) is subjected to screw rod (12) control, can open or draw in.Strut (6) can be made into shock reducing type.Last strutbeam (7) is the connector of last lower supporting rod.Following strutbeam (8) connection connecting rod (9), road wheel (11), road wheel (11) can be made into shock reducing type, screw rod (13) in interior screwed pipe (12) is rotatablely moved outward by interior, strut (6) is opened outward by interior, as Fig. 2, Fig. 3, wheel base can reach more than the 130cm, stretcher is special steady, belongs to the outer formula of opening.Change the position of strut (6), screw rod (13) ecto-entad in interior screwed pipe (12) revolves and opens strut (6), draws strut in to external rotation.As Fig. 4, Fig. 5, belong to internal expanding type.Rear walking wheel (11) can be made universal wheeled, is convenient to turn to.(18) for connecting plate, prevent to squeeze in the stretcher.

Stretcher (2) can be made into three sections, and front and back two sections (15), (17) are movable, and stage casing (16) connect lifter, and back segment (17) can be made backrest or seat or face upward.

During use, ambulance up and down for example only need shake handle (10) stretcher is elevated to the height of automobile, and the directive wheel (3) with the stretcher front end advances in the car earlier, put down support bar (4) and support the rear end of stretcher, thereafter shake handle (10) in the other direction, strut (6) is drawn in, carry on the road wheel, walked in the wheel pushing vehicle in front and back, buttress the stretcher rear end, pack up support bar (4), more whole lift truck is advanced in the car.Then opposite during following ambulance with above-mentioned steps.It is laborsaving again so promptly to economize the people.
