Detailed description of the invention
Embodiment to the blood purification multi-angle regulation care bed of the present invention below with reference to accompanying drawings
It is described in detail.
Within the hospital, if patient falls accidentally from sick bed, then the injury brought to patient is cannot
Estimate, this is because the state of an illness of some patients itself is easy to bring secondary injury because falling, example
Such as some patients, itself be subject to is the damaging, if fallen again under sick bed, then of muscle or muscles and bones
Exacerbate the state of an illness of self, it is also possible to some patients fall during treating under sick bed,
Also with medical care device, such as breathing mask etc. on health when falling, if fallen, then be likely to because of
Patient is caused to be in the boundary being in extreme danger for medical care device comes off.
Generally, patient is can to have a rest or receive treatment the most safely, is on the one hand
Because having medical personnel incessantly to carry out medical and nursing work, or have families of patients and look after for a long time,
Even if at night, it is also possible to arrange special nursing staff to retain one's original salary to patient and nurse, shorten
The unmanned nurse time of patient, on the other hand also in that some patients still have certain action energy
Power, to oneself having carried out self-specification, reduces the probability fallen from the bed.But, medical personnel,
Families of patients or even the nursing staff retained one's original salary are artificial nurse after all, oneself also have a meal, have a rest time
Between, it is impossible to carrying out patient uninterruptedly, the nurse of 24 hours, therefore, patient still exists certain
The unmanned nurse time, meanwhile, also having some patients is to completely lose ability to act, for these patients,
It is likely to stand up the generation resulting in pendant bed event the most unintentionally.
In order to avoid patient falls the generation of an event, in prior art, hospital management side also takes very
The most positive measure, such as, transforms sick bed bed body, increases the height of guardrail, and in disease
In bed bed body, some geofence equipment and emergence call equipments are set, fall the possibility of bed reducing patient
Property, providing the pendant triggering device that bed is reported to the police for patient, these improved sick bed equipment are to a certain degree
On decrease patient and fall the generation of an event.Meanwhile, hospital management side also takes some measures, example
As increased the interaction with families of patients and communication, to reduce the time of the unmanned nurse of patient.
But, it is excessively simple that these hospital bed structural reforms existing make mechanism, owing to patient falls between bed continues
Every the ofest short duration, above-mentioned detection and warning device accuracy of detection is the highest, detection efficiency is low, guardrail is high
The increase of degree and the increase of nurse time can only reduce patient and fall the probability of bed, and cannot be avoided pendant bed
Event occurs, and most importantly, lacks the fast reaction measure that patient falls an event in prior art
With fast reaction equipment, it is impossible to an event that falls patient carries out fast reaction, it is impossible in time to patient's body
Body quickly supports, and causes the ill effect that patient cannot be avoided to fall bed.
In order to overcome above-mentioned deficiency, the present invention has built a kind of blood purification multi-angle regulation care bed,
The pendant bed event of patient can be detected accurately and efficiently, it is possible to quickly report to the police, additionally it is possible to make
With some emergency reaction equipment, patient is given first aid to, thus be prevented effectively from patient and injured by shock.
