Description

Multifunctional physiotherapy bed

Technical Field

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

Background

In hospitals and physiotherapy rehabilitation places, some treatments require patients to lie on the bed and make various actions to complete the change of body posture, so that the physiotherapy bed is widely applied to the places.

As shown in the chinese patent of patent No. 201010298466.6, it discloses a multidirectional physiotherapy bed, including a bed body and a base, the bed body includes head supporting part, chest supporting part, shank supporting part, foot supporting part, and the shank handle is linked at foot supporting part rear portion, articulates in proper order between each part and forms, is connected with the well accuse part between chest supporting part and the shank supporting part. Although the physiotherapy couch has the lifting function, the backward bed body part of the leg support piece 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 can not completely meet the use requirement when a patient needs specific physiotherapy.

In order to improve comfort and functionality, the conventional physiotherapy couch is generally provided with corresponding armrest parts at two sides of the couch body, and the armrest parts can help patients get on and off the couch or sit up, but most armrests are detachably mounted at two sides of the physiotherapy couch in a sleeving manner 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 couch is inconvenient to use. The Chinese patent of 201020550682.0 discloses a physiotherapy couch armrest part, which comprises a support frame and an armrest pad connected with the support frame, wherein the support frame is of a connecting rod structure, and a locking device is arranged for locking an adjusting angle. The locking device mainly comprises a latch, a rotating clamp, a spring and other structures, and the angle locking is realized through cooperation of the latch, the rotating clamp, the spring and the like. The above locking device, although it performs the function of locking the angle, has the following drawbacks: 1. the structure is complex, and the assembly is complex and complicated; 2. during the use process, the sound of the engagement of the latch teeth is generated, and the noise is high; 3. after a period of use, latch wearing and tearing are serious, and the spring can also become invalid, influence normal use.

In addition, most of physiotherapy beds on the market are not provided with safety protection devices like the physiotherapy beds, when the whole bed descends, a patient is prone to lie on the bed body, hands are prone to hang down, the hands are easy to touch the metal frame of the bed body, and the whole bed cannot react and continuously descends to squeeze the hands to cause the patient to be injured.

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