Description

Multifunctional physiotherapy couch

Technical Field

The utility model relates to the field of medical mechanical equipment, in particular to a physiotherapy bed with safety protection function.

Background

In hospitals and physiotherapy rehabilitation places, some treatments require patients to lie on beds and make various actions to complete the change of body postures, so that the physiotherapy beds are widely applied in the places.

As shown in 201010298466.6's the chinese utility model patent, it discloses a diversified physiotherapy bed, including the bed body and base, the bed body includes head support component, chest support component, shank support component, foot support component, and the shank handle has been linked at foot support component rear portion, articulates in proper order between each part and forms, is connected with well accuse part between chest support component and the shank support component. Although the physiotherapy couch has the lifting function, the backward bed body part of the leg supporting part of the physiotherapy couch can only swing up and down and cannot be correspondingly rotated and adjusted. The existing physiotherapy couch has a certain adjusting function, but has incomplete functions, and cannot completely meet the use requirement when a patient needs specific physiotherapy.

In order to improve comfort and functionality, the existing physiotherapy bed is generally provided with corresponding armrest parts on two sides of a bed body, the armrest parts can help a patient to get on or off the bed or sit up, but most of armrests are detachably mounted on two sides of the physiotherapy bed in a sleeved mode at present, and although the armrests can be detached, the height, the angle and the like of the armrests cannot be adjusted, so that the physiotherapy bed is inconvenient to use. The chinese utility model patent of patent number 201020550682.0 has solved above problem, and it discloses a physiotherapy bed handrail part, including support frame and the handrail pad that is connected with the support frame, the support frame is link structure, sets up locking device simultaneously and is used for angle regulation's locking. The locking device mainly comprises a latch, a rotating clamp, a spring and other structures, and the locking of the angle is realized through the cooperation of the latch, the rotating clamp, the spring and the like. Although the locking device realizes the angle locking function, the locking device has the following disadvantages: 1. the structure is complex, and the assembly is complex and tedious; 2. the sound of the occlusion of the latch exists in the use process, and the noise is high; 3. after the spring is used for a period of time, the clamping teeth are seriously abraded, and the spring can also lose efficacy, so that the normal use is influenced.

In addition, most physiotherapy beds on the market are the same as above-mentioned physiotherapy bed and do not all be provided with safety device, when whole bed descends, the patient pronates on the bed body, and both hands hang down, and the metal frame of the bed body is touched to the hand very easily, and whole bed can not react and continue to descend and extrude the hand and make the patient receive the injury.

In summary, the current physiotherapy couch has limited functions and also has larger improvement space.

SUMMERY OF THE UTILITY MODEL
