Description

Mattress with dynamically-adjusted supporting position

Technical Field

The utility model belongs to the technical field of mattresses, and particularly relates to a mattress with a dynamically-adjusted supporting position.

Background

Mattresses are an important component of the sleeping environment of a person, and particularly for patients who are bedridden or physically weak, comfortable mattresses not only promote their sleep but also prevent the occurrence of stress injuries. The existing mattresses are generally simple in function, are large in thickness and are limited in deformation range, and the functions of assisting turning over of a patient lying in bed for a long time are difficult to achieve.

The bedridden patients with inconvenient movement or physical weakness can cause the long-term compression of local tissues to block the blood circulation and the continuous ischemia, hypoxia and malnutrition to cause the ulceration and necrosis of the tissues due to the continuous acting pressure and the incapacity of self-effective local decompression because of the long-term keeping of the same bedridden posture. Thus, a person lying in bed for a long period of time needs a caretaker to help him to turn over on a regular basis. It has been shown that intermittent pressure maintains blood perfusion in human tissue, reduces tissue damage, and reduces the probability of pressure damage by periodically changing the amount of pressure applied to the body part.

The first airbag strips 2-2 and the second airbag strips 2-3 are alternately arranged in sequence along the length direction of the mattress body 1. The first air bag strip 2-2 and the second air bag strip 2-3 are respectively connected with the first air pump 2-1 through independent electromagnetic reversing valves. The first air pump 2-1 is installed at a side portion of the mattress body 1.

In some embodiments, the auxiliary gesture adjustment module further comprises an auxiliary module 3; the supplementary module 3 and the adjustment module 2 are mounted on opposite sides of the mattress body 1, respectively. The auxiliary module 3 comprises a second air pump 3-2 and six air bag blocks 3-1; the six airbag blocks 3-1 are arranged in a matrix of 2×3.

The second air pump 3-2 is installed at a side portion of the mattress body 1.

As shown in fig. 2, in some embodiments, the mattress body 1 includes a body elastic layer 4 and a pressure distribution measurement module that are stacked from bottom to top. The main body elastic layer 4 plays a role of supporting and protecting an internal structure, and comprises six elastic blocks which are arranged in a 2×3 matrix shape; the adjacent elastic blocks are in rotary connection through cloth pieces; each elastic block comprises a sponge layer and a latex layer positioned above the sponge layer. The pressure distribution measuring module comprises six film pressure sensors 5; six membrane pressure sensors 5 are provided on the main body elastic layer 4 and aligned with the six airbag blocks 3-1, respectively.

The vital sign acquisition module comprises six vibration sensor groups 6; six vibrating sensor groups 6 are mounted in the sponge layer and aligned with the six airbag blocks 3-1, respectively. The vibration sensor group 6 includes four vibration sensors arranged in a matrix of 2×2. The model of the vibration sensor is SLPTT-50; the vibration sensor is used for collecting micro-motion signals of a bedridden person so as to obtain heart rate, pulse and respiratory rate data of the bedridden person lying on the mattress.

In some embodiments, the first controller 7 employs a single-chip microcomputer. Each membrane pressure sensor 5, as well as the vibration sensor, is connected to a first controller 7 via a signal processing module.
