Description

Antiskid sickbed

Technical Field

The utility model belongs to the technical field of medical instrument, a antiskid sick bed is related to.

Background

Sickbeds are also called medical beds and nursing beds, are used when patients are in rest, and are mainly used in various hospitals, village and town health hospitals, community service centers and the like. For inpatients or patients who need to be bedridden for a long time, if the patients lie down or keep a fixed position for a long time, the patients feel uncomfortable, the bed surfaces of most hospital beds are fixed and invariable, even if the bed head parts of the bed surfaces can be lifted, the patients can unconsciously move downwards due to the fact that the legs and the feet do not bear any weight when the patients sit up along with the lifting of the bed head, and therefore the patients need to move bodies from time to time when needed, and great troubles are caused to the patients. And in the process of moving the body of a patient or changing the height of the bed head of the bed, the mattress on the bed body can slide and shift, which is not beneficial to leaning and lying of the patient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an antiskid sick bed prevents that the patient's health from sliding when the head of a bed is raised.

In order to achieve the above object, the basic scheme of the utility model is: an anti-skidding sickbed comprises a bedstead, a headboard, a footboard fixedly installed on the bedstead, a bed frame hinged to one side of the headboard close to the footboard, mattresses arranged on the headboard and the footboard, and an anti-skidding mechanism, wherein the anti-skidding mechanism comprises a groove, a baffle plate and a piston cylinder;

the groove is arranged on the mattress and is opposite to the hip of the patient, and a baffle is connected in the groove in a sealing and sliding manner;

the piston cylinder is arranged on the bedstead and positioned below the headboard, a transverse piston plate is connected in the piston cylinder in a sealing and sliding manner, a piston rod is fixedly connected to the top of the piston plate, the top of the piston rod extends out of the piston cylinder, the end part of the piston rod is hinged with a sliding block, a sliding groove extending from the head of the bed to one side close to the footboard is arranged at the bottom of the headboard, and the sliding block is connected with the sliding groove in a sliding manner;

the bottom of the piston cylinder is communicated with the groove, the communicated space is a closed space, gas is filled in the closed space, and when the piston plate is positioned at the bottom of the piston cylinder, the upper surface of the baffle is flush with the upper surface of the mattress.

The working principle and the beneficial effects of the basic scheme are as follows: the headboard can swing relative to the bed frame, so that the requirements of leaning and sitting of a patient are met, and the structure is simple. The anti-slip mechanism is provided with the groove and the baffle plate, when the baffle plate retracts into the groove, the hip of a patient can fall into the groove on the mattress, and the groove is utilized to prevent the patient from sliding downwards. When the baffle was arranged groove notch in, the upper surface of baffle flushed with the mattress upper surface, avoided the mattress unevenness and influenced patient's use.

Simultaneously set up the piston cylinder structure in the below of headboard, linear motion about the top of piston rod can carry out along with the swing of headboard, drives patient and sits up like headboard upwards swing, and through slider and spout structure, the slider slides in the spout and guarantees that the piston rod is vertical state, indirectly drives the piston rod along with headboard rebound. The piston rod drives the piston plate to move upwards synchronously, at the moment, the space between the bottom of the piston cylinder and the piston plate is increased to form negative pressure, and gas in the groove is sucked into the piston cylinder, so that negative pressure is formed in the groove, and the baffle is driven to retract automatically to enter the groove. Therefore, according to the swinging angle of the headboard, the depth between the baffle and the groove notch is controlled, the larger the upward swinging angle of the headboard is, the larger the acting force which is required to slide downwards and is applied to a patient is, so that the downward moving distance of the baffle is longer, the sunken depth between the baffle and the groove notch is larger, more parts of the hip of the patient can be placed in the sunken part, and the anti-skid performance is enhanced.
