TECHNICAL FIELD

The invention relates to the field of medical instruments, particularly to a support device

for nursing bandaging.

BACKGROUND

In the emergency department of hospitals, patients with traumatic arms or legs and feet

are often encountered, and patients' wounds need to be disinfected and bandaged. In the

process of receiving patients from ambulances, patients need to be transported to hospital

beds by stretchers. However, due to the heavy weight of adults, it is often necessary for

many doctors to cooperate to transport patients from stretchers to hospital beds. Patients

need to be bandaged after they are transported to hospital beds. Because of injuries to

patients' legs and arms during bandaging, there are many inconveniences for patients to

move their postures. There is no device in the existing medical instruments to assist the

emergency department in treating injuries to patients' arms or legs and feet.

DESCRIPTION OF THE INVENTION

The technical scheme in the embodiments of the present invention will be described

clearly and completely with reference to the drawings in the embodiments of the present

invention. Obviously, the described embodiments are only part of the embodiments of the

present invention, not all of them. Based on the embodiments of the present invention, all

other embodiments obtained by ordinary technicians in the field without creative labor

belong to the scope of protection of the present invention.

In order to make the above objects, features and advantages of the present invention more

obvious and easy to understand, the present invention will be further explained in detail

with reference to the drawings and specific embodiments.

Embodiment 1

Referening to figures 1-4, this embodiment provides a support device for nursing

bandaging. It comprises a support plate 1. The bottom of the support plate 1 is rotatably

connected with walking wheels 7. Two parallel groove slide rails 102 are movably

connected above the support plate 1 in an up-and-down manner. One end of the groove

slide rail 102 is hinged with an inclined groove slide rail 3. Lifting support components

are arranged between the two groove slide rails 102. The lifting support components are

located between the support plate 1 and the groove slide rails 102. A storage box 6 is fixedly connected to the top of the support plate 1. Pulling parts are arranged outside the ends of the two groove slide rails 102. The pulling parts are detachably connected to a stretcher 8 through a first steel wire 5.

In the invention, pulling parts are arranged outside the groove slide rails 102. The pulling

parts pull the first steel wire rope 5, and then the first steel wire rope 5 pulls the stretcher

8, so that the stretcher 8 is moved above the groove slide rails 102 along the inclined

groove slide rails 3. The groove slide rails 102 are set in a lifting mode. When the

stretcher 8 moves to the top of the groove slide rails 102, the inclined groove slide rails 3

can be naturally vertical under the action of gravity by raising the groove slide rails 102.

Therefore the occupied space of the whole device is reduced. In addition, lifting support

components are arranged between the groove slide rails 102. The lifting support

components are used for supporting patients, thus facilitating the medical staff to bandage

the patients.

In a further optimization scheme, four support hydraulic cylinders 101 are fixedly

connected to the top of the support plate 1, and they are vertically arranged. The top of

each support hydraulic cylinder 101 is fixedly connected with the bottom of a groove

slide rail 102.

By controlling the lifting of the support hydraulic cylinders 101, the lifting function of the

groove slide rails 102 is realized, thereby facilitating the folding of the inclined groove

slide rails 3.

In the further optimization scheme, the lifting support components comprise a lifting

plate 2 which is movably arranged on the top of the support plate 1 in an up-and-down

manner. A plurality of lifting hydraulic cylinders 203 are fixedly connected to the top of the lifting plate 2, and they are vertically arranged. The top ends of the lifting hydraulic cylinders 203 are fixedly connected with support blocks 204. The support blocks 204 are used to support the human body. By controlling the lifting of the lifting hydraulic cylinders 203, the support blocks 204 are driven to lift. The lifting of the support blocks

204 can support the movement of the legs and arms of the human body, thus facilitating

the medical staff to bandage the patient.

In the further optimization scheme, the four corners of the lifting plate 2 are threaded

with ball screws 202. The bottom ends of the ball screws 202 are axially connected with

the output shafts of lifting motors 201. The lifting motors 201 are fixedly connected with

the support plate 1. By controlling the rotation of the lifting motors 201, the lifting motors

drive the ball screws 202 to rotate, therefore move the support plate 1 up and down.

In the further optimization scheme, the number of support blocks 204 is at least six,

which respectively correspond to the arms, back, hips and legs of the human body.

In the further optimization scheme, a pulling part comprises a first guide wheel 103

rotatably connected to the outer side of one end of the groove slide rail 102 and a second

guide wheel 104 rotatably connected to the outer side of the other end of the groove slide

rail 102. The second guide wheel 104 is located at one side close to the inclined groove

slide rail 3. A biaxial motor 106 isfixedly connected below the groove slide rails 102.

The biaxial motor 106 is located below the second guide wheel 104, and it is axially

connected with the winding wheel 105. One end of the first steel wire rope 5 is fixedly

connected with the winding wheel 105. The first steel wire rope 5 sequentially passes

around the first guide wheel 103 and the second guide wheel 104. The other end of the

first steel wire rope 5 is fixedly connected with the hook 9. By controlling the rotation of the biaxial motor 106, the biaxial motor 106 drives the winding wheel 105 to rotate. The winding wheel 105 winds the first steel wire rope 5 to pull the first steel wire rope 5, thereby pulling the hook 9 to move.

In the further optimization scheme, one end of the support rod of stretcher 8 is fixedly

connected with hook ring 801. The bottom of the support rod of stretcher 8 is rotatably

connected with four rollers. The groove bottoms of groove slide rails 102 are provided

with braking grooves 1021. The width of the braking groove 1021 is matched with the

width of the roller, and the length of braking groove 1021 is smaller than the diameter of

the roller.

After the stretcher 8 moves to the groove slide rails 102, the rollers move in the groove

slide rails 102 along with the movement of the stretcher 8. When the rollers move to the

braking grooves 1021, a part of the rollers fall into the braking grooves 1021 to realize

the position locking of the stretcher 8.

In the further optimization scheme, the storage box 6 has a multi-grid structure with a

door body. The medical supplies are stored in the multi-grid structure.

The working process of this embodiment is as follows.

First, put the patient on the stretcher 8, open the inclined groove slide rails 3. Control the

support hydraulic cylinders 101 to descend to make the groove slide rails 102 descend.

The inclined groove slide rails 3 realize docking with a docking surface (vehicle cabin or

ground, etc.). Then, sequentially pass the first steel wire rope 5 around the first guide

wheel 103 and the second guide wheel 104. Hook the hook 9 with the hook ring 801 on

the stretcher 8, and control the biaxial motor 106 to rotate. The biaxial motor 106 drives

the winding wheel 105 to rotate, and the winding wheel 105 winds the first steel wire rope 5 to pull the first steel wire rope 5. Therefore, the hook 9 is pulled to move, and the hook 9 is pulled to pull the stretcher 8. Move the stretcher 8 above the groove slide rails

102 along the inclined groove slide rails 3. After the stretcher 8 is moved onto the groove

slide rails 102, the rollers move in the groove slide rails 102 along with the movement of

the stretcher 8. When the rollers move to the braking grooves 1021, a part of the rollers

fall into the braking grooves 1021 to lock the position of the stretcher 8. At this time, the

support hydraulic cylinders 101 are controlled to rise, and the groove slide rails 102 also

rise. The inclined groove slide rails 3 are naturally vertical under the action of gravity,

thus reducing the occupied space of the whole device. Then, the lifting motors 201 are

controlled to rotate. The lifting motors 201 drive the ball screws 202 to make the support

plate 1 move upwards. Therefore all the support blocks 204 contact with the patient. At

this time, the cloth on the stretcher 8 can be detached from the stretcher 8 (detachable

stretcher structure can be selected). If the patient's leg needs to be bandaged, but the angle

of the patient's leg is inappropriate, the corresponding lifting hydraulic cylinders 203 are

controlled to drive the support blocks 204 to move up or down. Therefore, the adjustment

of the patient's leg can be realized to facilitate the medical staff to bandage the patient.

Embodiment 2

Referening to figures 5-11, the support device of this embodiment differs from the first

embodiment as follows.

Vertical chutes are provided on the top surface of the support plate 1. Stoppers 4 are

slidably connected in the vertical chutes. A spring 402 is fixedly connected between the

bottom surface of a stopper 4 and a vertical chute. One end of the inclined groove slide

rail 3 far away from the groove slide rail 102 is provided with an inclined surface, on which first stop teeth 301 are fixedly connected. The upper surface of the stopper 4 is fixedly connected with second stop teeth 401. The first stop teeth 301 are matched with the second stop teeth 401. Through the mutual cooperation between the first stop teeth

301 and the second stop teeth 401, the inclined groove slide rails 3 will stop when they

sag under the action of gravity. The inclined groove slide rails 3 will be prevented from

shaking during the transfer process of the hospital bed, thus injuring the medical staff.

The first stop teeth 301 also have anti-skid function. When the inclined groove slide rails

3 are placed obliquely, the first stop teeth 301 contact with the transverse surface. This

has a certain anti-skid function and prevents the inclined groove slide rails 3 from moving

relatively.

A rotating shaft 205 is fixedly connected to the top surface of the lifting hydraulic

cylinder 203. The bottom of the support block 204 is rotatably connected with the

rotating shaft 205. A torsion spring 206 is sleeved outside the rotating shaft 205. One end

of the torsion spring 206 is fixedly connected with the support block 204 and the other

end is fixedly connected with the rotating shaft 205. By arranging the rotating shaft 205

and the torsion spring 206, when the support block 204 contacts with the patient, the

lifting hydraulic cylinder 203 can be controlled during lifting process to ensure that the

support block 204 and the legs and arms of the patient are in a good contact. This can also

prevent the edge of the support block 204 from hurting the patient.

The support rod of the stretcher 8 includes a first connecting block 802, a plurality of

second connecting blocks 803 and a third connecting block 804 which are arranged in

sequence. Steel wire rope through holes are provided at the center of the first connecting

block 802, a plurality of second connecting blocks 803 and the third connecting block

804. The end of the first connecting block 802 close to the second connecting block 803

is provided with a clamping groove. The end surface of the second connecting block 803

close to the first connecting block 802 is provided with a clamping protrusion. The

clamping groove and the clamping protrusion are mutually matched. The end surface of

the second connecting block 803 away from the first connecting block 802 is provided

with a clamping groove. The end surface of the third connecting block 804 close to the

second connecting block 803 is provided with a clamping protrusion. The steel wire rope

through hole is penetrated with a second steel wire rope. One end of the second steel wire

rope is fixedly connected to the first connecting block 802. The steel wire rope through

hole of the third connecting block 804 far away from the second connecting block 803 is

threaded with a bifurcation screw 805. The bifurcation screw 805 is a screw with a gap on

the end side wall (its structure is similar to that of an expansion bolt). The second steel

wire rope passes through the bifurcated screw 805. The first connecting block 802, a

plurality of second connecting blocks 803 and a third connecting block 804 can form a

rod shape with a fixed structure by tightening the second steel wire rope. Then, by

tightening the branching screw 805, the end gap of the branching screw 805 gradually

becomes smaller, therefore the other end of the second steel wire rope is fixed for

carrying patients. When the stretcher 8 is transported to the groove slide rail 102 and

fixed, the branching screw 805 is loosened. At this time, the support rod of the stretcher 8

becomes a flexible structure, therefore assisting the operation of the support block 204.

Two inverter blocks 1022 are rotatably connected in a braking groove 1021. Stop pins

1023 are arranged below the inverter blocks 1022. They are fixedly connected with the

braking groove 1021. When the rollers of the stretcher 8 pass through the inverter blocks

1022, the inverter blocks 1022 are kept stationary due to the action of the stop pins 1023.

Therefore the rollers can move smoothly. As the rollers continue to travel, when the

rollers travel to the middle position of the two inverter blocks 1022, the inverter blocks

1022 turn over. Therefore the rollers fall a certain distance, and the position of the

stretcher 8 is locked.
