Description
Technical field
The present invention relates in medical instrument, a kind of hospital bed with rotation function
Background technique
Hospitals at Present treatment acute respiratory distress syndrome and patient bedridden in long term lead to hypostatic pulmonary infection, atelectasis
The mode of general therapeutic has assisted mechanical ventilator, prone-position ventilation, deep breathing method, claps back-packing, lash method and atomization eliminating the phlegm.
In hospital ward abundant expectoration caused by and pulmonary infection comprehensive to acute respiratory distress, atelectasis treatment usually with
Prone-position ventilation method.Prone-position ventilation implementation method in clinical at present: must be by 3-4 trained health care professionals
Implement external treatment.When converting prone position, patient, which is now translated bed side, makes patient lying-on-side to hospital bed to side to overturn, then will
Prone position is passed to after buttocks, shoulder.It is amesiality, it is fixed with head circle；The soft pillow of both shoulders underlay, the soft pillow of lower part of the body pad, does not make abdomen
Portion is pressurized, and arm is stretched out, and guarantees that each tracheal catheter, ventilator pipe and other drainage tubes etc. are unimpeded.
It can be seen that the patient of long-term bed by the case where above treatment method, will generate leads to hypostatic lung
Infection, lobar collapse atelectasis, and a large amount of sputum will be generated, sputum cannot exclude by itself, using the above deep breathing method, clap
Back-packing, lash method method effect are very unsatisfactory, finally use prone-position ventilation method, and drawback is also more: it needs more people to move
Patient easily causes the displacement of various pipelines and falls off, lead to the generation of adverse events, or even jeopardizes patients ' lives.Do not close
Suitable mattress gives strong support when being patients underwent prone-position ventilation, external to be easy displacement, Head And Face, both shoulders, pelvic support
Point part is since by gravity, long-time local pressure is easy to produce pressure sore.Only lifting medical hospital bed at present, translation, side
The function of position and the padded head of a bed, tailstock is unfavorable for postural drainage expectoration and the treatment of row prone-position ventilation, brings many pains to patient
Hardship is also easy to other organs of injured patients, brings many complication, can make patient sb.'s illness took a turn for the worse aggravation, can not eradicate disease
Source.
