Description

a nursing bed

technical field

The invention relates to the field of nursing beds, in particular to a nursing bed.

Background technique

In recent years, with the sharp increase in the number of elderly people, more and more elderly people are unable to take care of themselves completely. The number of disabled people due to disasters and diseases is also increasing, and they have different degrees of disability. Traditional nursing beds can no longer fully meet these requirements. For the needs of people's daily life, for the patients, the elderly, the disabled and other long-term bedridden people, it is very inconvenient to move, and they are basically unable to take care of themselves in daily life. It brings a lot of inconvenience and trouble to nursing work; most nursing beds on the market currently use the manual fecal collection function, that is, when the bedridden goes to the toilet, the nursing staff needs to move the mattress more or less manually. On the one hand, the work intensity of nursing staff is high, and on the other hand, it will cause great pain to the bedridden, and the bedpan currently used is only an ordinary basin, which is inconvenient to use, so patients often wet the bed sheet Dirty, which brings great trouble to the cleaning and nursing staff.

As shown in Figures 1-8, in the initial state, the flip-up concealed bisected mattress 2 is located on the bedpan placement port 11, and the urine-proof mobile bedpan device 3 is located below the bedpan placement port 11. When the bedridden needs to go to the toilet , the flip-up hidden split-type supplementary mattress 2 is contracted by the push rod end of the first push rod mechanism 24, so that the linkage rod 231 moves to the right, and at the same time drives the first swing rod 232 and the second swing rod 235 to move to the left, As a result, the first connecting rod 233 is moved to the left, so that the first supplementary mattress bracket 234 is turned downward, the first swing rod 232 is moved to the left, and the second connecting rod 236 is moved to the left, thereby driving the third swing. The rod 237 moves to the right, thereby driving the third connecting rod 238 to move to the left, so that the second supplementary mattress bracket 239 is flipped downward to realize the first supplementary mattress body 21 and the second supplementary mattress body 22 Turn down, while turning the concealed folio supplementary mattress 2 to turn over, the splash-proof bedpan 33 on the bedpan bracket 32 drives the rotation of the rotating shaft 335 through the contraction of the second push rod mechanism 333, thereby driving the cover The plate 332 is opened, and the first baffle 51 and the second baffle 52 are folded in half through the sliding of the pulley 53 on the chute 55. The bedpan 33 moves down along the vertical sliding table 311 to the bedpan placing port 11 , and after moving to a suitable position, the bedridden goes to the toilet. After use, the splash-proof bedpan 33 moves down along the vertical sliding table 311 and leaves the bedpan placing port 11 . Afterwards, the second push rod mechanism 333 extends to drive the cover back to its original position. At the same time, the first push rod mechanism 24 extends to move to the left with the linkage rod 231 and drives the first swing rod 232 and the second swing rod 235 at the same time. Move to the right, so that the first connecting rod 233 moves to the right, so that the first supplementary mattress bracket 234 is turned up and returned to the position, the first swing rod 232 moves to the right, and drives the second connecting rod 236 to move to the right, Therefore, the third swing rod 237 is driven to move to the left, thereby driving the third connecting rod 238 to move to the right, so that the second supplementary mattress bracket 239 is turned up and returned to the original position, so that the nursing bed can be restored to its original state, and no manual operation is required during use. Move the supplementary mattress and bedpan, and at the same time, through the urine-proof mobile bedpan device, the patient can reduce the wetness and soiling of the bed sheet to reduce the difficulty of nursing during the toileting process of the bedridden, thereby reducing the work intensity of the nursing staff and the pain of the bedridden It has the characteristics of simple structure, convenient operation, safety and reliability, etc.
