Description

Transfer stretcher

Technical Field

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

Background

Transport stretchers are commonly used for outdoor emergency use, such as in use scenarios from a fire scene onto an ambulance, from a car accident scene onto an ambulance, from a geological disaster area onto a rescue vehicle, and the like.

Present transportation stretcher mainly adopts the integral type structure, after transporting wounded, stretcher surface cushion can bond blood with wounded contact site, can't wash it or change, long-time back cushion of using easily breeds the bacterium, influence its safety in utilization, when long distance (the long distance here indicates more than or equal to 80 meters) lifts the transportation wounded, easily make the staff tired, although current transportation stretcher also has walking function a little, running gear and stretcher main part structure as an organic whole, lead to whole volume great, storage when not being convenient for idle is accomodate, consequently, need make corresponding improvement to the above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a transport stretcher to the inconvenient dismantlement that provides among the above-mentioned background art of solution is washd the cushion, and the difficult problem of accomodating of transfer device.

The utility model provides a transport stretcher, which comprises a bracket, the bracing piece is equidistant to be fixed on the support, the bracing piece up end is provided with the cushion, the support inboard still equidistant be fixed with the link, the cushion edge is connected with the couple through the stretch cord, couple and link lock joint each other, the fixed plate symmetry is fixed in the support left and right sides, still be fixed with the anti-skidding handle on the fixed plate, still be connected with the slide bar that can slide from top to bottom on the fixed plate, the terminal surface has rotatable bull stick through the cylindrical axle connection under the slide bar, the bull stick other end passes through cylindrical axle swivelling joint on the gag lever post, first spring cup joints on the slide bar, first spring upper end links firmly with terminal surface under the fixed plate, first spring lower extreme is contradicted on slide bar middle part boss, gag lever post sliding connection is at the support lower extreme, still be fixed with being used for spacing dog on the gag lever post, the gear passes through cylindrical axle swivelling joint under the support terminal surface, gear and dog meshing, gear and elasticity telescopic link head end fixed connection, the terminal fixedly connected with universal wheel of elasticity telescopic link, still be provided with the torsion spring between gear and the support, and torsion spring is the central line is symmetric distribution about the gear central line.

The utility model has the advantages that:

elastic telescopic rod can overturn, both can make things convenient for device's storage, and convenient again to wounded's transportation, elastic telescopic rod can realize certain cushioning effect simultaneously, guarantees wounded's stability in the transportation, causes the secondary injury to wounded when avoiding transporting, cooperates the detachable cushion, makes things convenient for the later stage to wash the change to the cushion, avoids bacterial growing to influence the safe in utilization of cushion.

Detailed Description

Referring to fig. 1-5, a transfer stretcher includes a support 1, side rails 2 are symmetrically fixed on the upper end surface of the support 1, vertical bars 3 are fixed on the side rails 2 at equal intervals, the lower ends of the vertical bars 3 are fixed on the support 1, support bars 4 are fixed on the support 1 at equal intervals, a cushion 12 is arranged on the upper end surface of each support bar 4, hanging rings 13 are further fixed on the inner side of the support 1 at equal intervals, the edges of the cushion 12 are connected with hooks 1202 through elastic ropes 1201, the hooks 1202 and the hanging rings 13 are fastened with each other, a fixing plate 5 is symmetrically fixed on the left side and the right side of the support 1, an anti-slip handle 6 is further fixed on the fixing plate 5, a slide bar 7 capable of sliding up and down is further connected on the fixing plate 5, a rotatable rotating bar 8 is connected on the lower end surface of the slide bar 7 through a cylindrical shaft, the other end of the rotating bar 8 is rotatably connected on a limiting bar 9 through a cylindrical shaft, a first spring 701 is sleeved on the slide bar 7, the upper end surface of the first spring 701 is fixedly connected with the lower end surface of the fixing plate 5, the lower end surface of the first spring 701 is abutted on a boss of the slide bar 7, the lower end surface of the support 1 is connected with a torsion gear 1002, a universal gear 1002, and a universal gear 1002 is connected with a universal gear 1002, and a universal gear 1002 are connected between the end surface of the telescopic rod 1002, and a universal gear 1002.

The working principle is as follows: as shown in fig. 1-5, before use, firstly, the clean cushion 12 is installed, the cushion 12 is placed on the upper end surface of the support rod 4, the position of the hook 1202 is adjusted through the elastic action of the elastic rope 1201 until the hook 1202 and the hanging ring 13 are fastened with each other, so that the installation of the cushion 12 is realized, the disassembly of the cushion 12 can be realized according to the principle, and the cushion 12 is convenient to clean at the later stage;

when the stretcher is used, the stretcher is moved to the side of the wounded, the wounded is lifted to the soft cushion 12, and the wounded can be limited by the side rails 2 and the vertical rods 3, so that the wounded is prevented from sliding off;

when transporting the wounded, if the road surface is comparatively level, at first hold anti-skidding handle 6, will wounded and support 1 lift a distance (here distance is greater than the length of elastic telescopic rod 10), use the thumb to press slide bar 7, slide bar 7 moves down, bull stick 8 can carry out the upset of certain angle, it slides to the outside to drive gag lever post 9 when bull stick 8 overturns, make dog 901 and gear 1002 separate, at this moment under torsion spring 11's effect, make gear 1002 and elastic telescopic rod 10 rotatory 90 to vertical state, the staff loosens slide bar 7, slide bar 7 slides up under the effect of first spring 701, resume the normal position, according to above-mentioned principle, gag lever post 9 resumes the normal position and carries out the block with gear 1002, guarantee the stability of elastic telescopic rod 10, thereby make whole device launch, cooperate the effect of universal wheel 1001, conveniently realize the wounded and transport, and in the transportation, and through the elastic damping effect of elastic telescopic rod 10, can realize the buffering shock attenuation, avoid causing the secondary injury to the wounded, elastic telescopic rod 10 is the structure known in the prior art, it includes sleeve and sets up the damping pole in the sleeve inside.

If the road surface is uneven or steps exist, a worker can directly hold the anti-skid handle 6 to assist in lifting and transporting the wounded, and the elastic telescopic rod 10 does not need to be rotated to be in a vertical state.
