Background

Stroke is also known as stroke and cerebrovascular accident. Is an acute cerebrovascular disease, which is a group of diseases causing brain tissue damage due to sudden rupture of cerebral vessels or failure of blood flow into the brain due to vessel occlusion, including ischemic and hemorrhagic stroke. The stroke emergency bed generally has a weighing function, and venous thrombolysis in a stroke time window needs to be determined according to the weight of a patient; the patient of apoplexy is the hemiplegia in many, and some are poor from the nature in addition, and unwilling complex condition takes place occasionally, need drag to the CT platform of lying on lying from the sick bed when doing inspection such as CT, not only very inconvenient, appear scotch easily moreover, jolt too big etc. be unfavorable for the patient's condition.

Disclosure of Invention

The invention aims to provide a stroke emergency cot convenient for transferring patients, aiming at the problems in the prior art, and the technical problem to be solved by the invention is how to enable a bed board to be capable of offsetting and lifting and to be convenient for transferring the patients.

The purpose of the invention can be realized by the following technical scheme: a stroke first-aid bed convenient for a patient to transfer is characterized by comprising a bed frame, a bed board and a transfer board, wherein the transfer board is arranged on the bed board, a plurality of cylinders are arranged between the lower surface of the bed board and the bed frame, each cylinder comprises a cylinder body and a push rod, hinge structures are respectively arranged between the cylinder body and the bed frame and between the push rods and the bed board, each hinge structure comprises a hinge ball, a hinge bowl and a guide control assembly, the hinge ball is rotatably connected with the hinge bowl to form a ball hinge pair, the guide control assembly comprises four limiting rods, four guide grooves arranged along the inner wall surface of the hinge bowl and electromagnetic valves for controlling the expansion and contraction of the limiting rods, four guide sliding holes respectively corresponding to the four limiting rods one by one are formed in the hinge ball, the four limiting rods are distributed in a cross shape, the inner ends of the two limiting rods on the same straight line are respectively hinged with a connecting rod, the inner ends of two connecting rods for connecting two limiting rods on the same straight line are hinged to a pressing block, an interval is reserved between the two pressing blocks, the two pressing blocks are fixedly connected through a pull rod, and the moving part of the electromagnetic valve is fixed on the pull rod.

Furthermore, a mounting cavity is formed in the hinged ball, a fixing piece of the electromagnetic valve is fixed on the inner wall of the mounting cavity, a moving piece of the electromagnetic valve is connected in the mounting cavity in a sliding mode along the axial direction of the pull rod, and the pull rod is perpendicular to the limiting rod.

Furthermore, the bed board is formed by two half boards hinged together, and two cylinders are arranged between each half board and the bed frame.

Furthermore, two limiting rods which are positioned on the same straight line are arranged along the length direction of the bed plate.

Furthermore, both sides of the bed frame are respectively provided with a notch, the edge part of the bed board is hinged with a guard plate corresponding to the notch, the two ends of the guard plate along the length direction of the bed board are respectively hinged with an extension plate, and the extension plates can be superposed with the guard plates.

Furthermore, the front end and the rear end of the bed frame are respectively provided with a guardrail.

Further, the lower surface of the transfer plate is provided with a plurality of rollers.

Further, bed board and transfer board are the fretwork board, the board that shifts includes the hard layer of bottom and the soft layer of hard layer top, and the gyro wheel rotates to be connected on the hard layer.

The bedstead is provided with a sink step, the bed board and the transfer board can be arranged in the sink step, and at the moment, the transfer board is limited by the peripheral cross rod.

The push rod of the air cylinder is connected with the cylinder body through a spline, can be drawn and can not rotate relatively, and the allowed swinging direction of the hinge can be controlled through a hinge structure, or the hinge is locked, for example: when the bed plate is swung to be L-shaped relative to the other end close to the head part so as to facilitate a patient to sit, the half plate in the horizontal state is hinged and limited, namely, the cylinder body of the cylinder is not allowed to swing relative to the bed frame, the bed plate is not allowed to swing relative to the push rod of the cylinder, and only the turning half body is allowed to swing around the turning direction.

When the four limiting rods extend out of the hinge ball, the ends of the limiting rods are respectively inserted into the corresponding guide grooves, so that the hinge ball and the hinge bowl cannot relatively slide, namely, are locked.

This emergency cot can realize the bed board to the one side translation of bedstead, raise the bed board promptly, then promote the bed board to bed board one side translation to the bed board shelve steadily to lean on the bedstead, this deformation can pull out the patient on the bed board to open bedstead one side in more space, has more open space in the operation process such as patient shifts, patient emergency operation, ties up and ties up, patient's head and shank also have better operating space because of the restriction that breaks away from the guardrail at bedstead both ends.

In the first aid process of the patient, the two half bodies of the bed plate do not have the requirement of overturning, so the transfer plate can be a hard plate.

When a patient is transferred to a lying plane of other medical equipment such as a CT (computed tomography) bed, the extension plates on the two sides of the guard plate are unfolded, the guard plate and the extension plates are swung, so that the extension plates serve as transition plates between the bed plate and other platforms, the height of the bed plate can be controlled, the transfer plates can be slid to other platforms, the patient is not directly contacted with the bed plate and the guard plates, and the patient is prevented from being scratched.

When the extension plate is unfolded, the guard plate can be in a state of being vertical to the bed board under the limiting action of the bed frame on the two sides of the notch, and when the extension plate is folded to be superposed with the guard plate, the guard plate can swing to droop.

In the rehabilitation period of the patient, the transfer plate can be taken away, and the folding of the bed plate can be realized, so that the patient is in a sitting posture.

The offset of the bed board can assist the transfer of the patient, so that the operation is more convenient, and the extension range of the bed board is larger.

Therefore, the emergency cot can realize the functions of lifting the cot plate, turning the cot plate to a sitting and standing state, shifting the cot plate, transferring a patient without damage and the like.
