Description

Adjustable length stretcher

This utility model relates to a kind of stretcher.The technical field that belongs to hospital's apparatus.

As everyone knows, existing cot construction is simple, function singleness, and majority is being lifted carrying patient by the people.Along with the urbanization of society, the high-rise building emerge in multitude, for saving the space, their used lift spaces are all very little, fail to lay down existing stretcher.Hold high-rise critical patient and when rescuing, only carry, lifting downstairs, or on the corridor, go downstairs with stretcher by the people.Be unfavorable for so very much the state of an illness, more incured loss through delay the opportune time that gives emergency treatment to a patient.

The purpose of this utility model is the shortcoming that overcomes existing stretcher bad adaptability, designs a kind of variable-length, the conventional lift and be convenient to the stretcher of corridor up and down of coming in and going out.For more convenient, transport patient more efficiently, with stretcher supporting have one can fold rapidly and have wheel, and have the pallet of vibroshock.

The purpose of this utility model is achieved in that it and overlaps hinge means with one and connect and lock along a bed frame length direction, be divided into two sections or three sections according to the position of human body upper body, thigh, shank bending by one, and it can be stretched and bend to Or

Shape, the stretcher that the variable-length that angle of bend can be regulated as required is short makes it can pass in and out conventional lift.For quick and easy the personnel selection lifted, with the bed frame supporting a pallet arranged.It is isolating with the bed frame structurally or lumps together, and it is a pedestal with four vibroshocks framework that to be column be welded into the four directions with rod member on every side; The principal post lower end connects two groups of footposts that have wheel with hinge.Retractable mechanism by the operation footpost gets off from rescue, and footpost puts down, and packs up during last ambulance to be folded in below the pedestal.

Below in conjunction with drawings and Examples this utility model is further specified.

Embodiment 1:

Fig. 1,2,3,4, the 5th, the structure diagram of present embodiment.

Above-mentioned adjustable length bed frame, shown in Fig. 1,2,3,4,5: it is knockdown by " n " type member 1,

joint

13,14, support bar 8 and straight-bar are formed the main frame of a sealing." n " type member 5.Be connected with main frame by the hinge means that constitutes by joint 11,13, pin 2.When " n " type spare 5 when axle 2 forwards horizontal level to, hole 4 is concentric with hole 3.When pin is inserted into hole 3, hole 4, make " n " type spare 5 be fixed on horizontal level, reach the variable purpose of a frame length.Bed frame inboard is provided with a collection of hook 6.Be used for hanging along the bed length direction and be divided into some fritter bed drawer.Like this to the patient that do not allow to move as long as stretcher is placed on the operating-table, fritter bed drawer is taken from the bed frame, and patient " is leaked down " from the bed frame, and then one one is extracted out fritter bed drawer down from patient's body.Fritter bed drawer structure is standardized feasible exchange, can equally with clothing of hospital etc. sterilize and circulate.

The cabinet base 9 that can insert damping device is housed on joint 13,14.For the ease of inserting, cabinet base will have certain tapering.

With the supporting pallet of bed frame, shown in Fig. 1,2,3,4,5.It is a column with four vibroshocks and rod member on every side is welded into tetragonal rigid frame as pedestal.With four lower limbs 16, connecting rod 18, form quadric chain jointly.Utilize locating slot 20 and gag lever post 17 on the fixed pedestal to control fixing of quadric chain or swing.

Stretcher is placed on the pallet of motion or all can be subjected to more intensive vibration on ambulance.For vibration damping, four spring cushions are arranged on the pallet.When pushing to ambulance, stretcher, auxiliary wheel 22 is housed under two dampings in front for reducing vibrations and advancing car quickly.

Embodiment 2:

Fig. 6,7,8, the 9th, the structure diagram of present embodiment.

This adjustable length stretcher is shown in Fig. 6,7,8,9.It is by the square box 1,5,11 of 3 sealings; On the pallet that is connected and fixed by

axle

2,3,4,7,8.When with wrench rotating screw bolt 23, make slide block 22 drive axle 3,4 and move up and down, thus the angle of change frame 1,5.But the angle of this adjusting is limited, and is too small to special patient or elevator, corridor, in order to increase adjusting angle, regulates with bracing frame 32.One end of bracing frame is connected with frame 1 with hinge 34.There are several minor axises 35 its both sides, when they enter the position of axle 2 successively, different angles have just been arranged.These two kinds of angle regulators can have simultaneously or select for use a kind of.Part 36 is the active briquettings of energy, and it can push down the minor axis 35 on axle 2 and the bracing frame, and frame 1 is fixed.When frame 11 when axle 8 forwards horizontal level to, hole 10 is concentric with hole 9.Be inserted in hole 10, the hole 9 with pin, make frame 11 fixed level positions, reach adjustable length purpose.

Be connected front and

back footpost

18,21 on the pedestal by axle,, constitute leg-of-mutton bar linkage structure with pedestal respectively with gag lever post 16,19.Part 30,31 and pedestal have been formed quadric chain.When carriage release lever 31, bar 30 is stirred locating shaft 28, controls the fixing or swing of two groups of footposts.Because two groups of footposts directly do not connect, their folding and unfoldings simultaneously or folding and unfolding separately.Downstairs the time, can only will pack up from stair when stretcher, and make the gradient of the difference in height of auxiliary wheel and another footpost wheel and stair approaching, front and back wheel can both be landed, and be convenient to go downstairs near the footpost of head.

Embodiment 3:

As shown in figure 10: the bed frame is divided into two at length direction, porose or special-shaped groove on; One section and above-mentioned hole are arranged, the bar that can insert that special-shaped groove matches on another.Change the length of a frame with the depth of inserting.There is a collection of hook that is used for hanging a drawer inboard of bed frame.Length according to the bed frame increases, reduces the piece number of piece bed drawer.

For weight reduction, the rod member of forming stretcher are to make with the composite that contains glass fibre or shapings such as carbon fiber, resin.
