Patient transferring bed and chassis device thereof

Abstract

The invention relates to a medical auxiliary bed, in particular to a patient transferring bed and a chassis device thereof. The transferring bed comprises a bed body, a chassis, brake devices and a guiding device. Brake devices comprise brake rods. The guiding device comprises guiding wheels and wheel frames which are used for assembling the guiding wheels. A transmission arm is fixedly assembled on each brake rod and is intersected with an corresponding brake rod, the transmission arms located on the two brake rods correspond to each other, the adjacent ends of the mutual-corresponding transmission arms are both extend inwards, a rotatable center control shaft which extends forwards and backwards is assembled on the chassis, the center control shaft enables the adjacent ends of the mutual-corresponding transmission arms to be synchronically connected together in an equidirectional and transmission mode through two connecting levers arranged at two ends of the center control shaft, at least one brake rod is connected with an operation handle which is used for driving the brake rod to rotate around an axis, and a cam mechanism which is used for being in press fit with the wheel frames and controlling the heights of the guiding wheels is arranged on the center control shaft. The patient transferring bed and the chassis device thereof solve the problem that an existing patient transferring bed cannot be simultaneously operated for braking and guiding.

Description

technical field [0001] The invention relates to a medical auxiliary bed, in particular to a patient transfer bed and its chassis device. Background technique [0002] In the prior art, four casters are provided on the chassis of the patient transfer bed, and the caster wheels are universal wheels, which are used to provide convenience for patient transfer. However, since the four casters are universal wheels, it is very easy to cause the bed to collide with the wall or the surrounding people due to factors such as inertia during the moving process, especially when turning. The casters also need to be locked to prevent them from slipping automatically. Aiming at the problem that the hospital bed will automatically slide, the Chinese patent application No. 2001201153966 discloses a caster brake device for the hospital bed. It extends in the direction and is respectively driven and connected with brake actuators at both ends. The brake actuators include eccentric devices corr...
