Embodiment
The embodiment of the blood purification multi-angle regulation operation table of the present invention is carried out specifically below with reference to accompanying drawings
It is bright.
Within the hospital, if patient falls from sick bed accidentally, can not estimate to the injury that patient brings, this is
Because the state of an illness of some patients in itself is easy to bring secondary injury because falling, such as some patients, what is itself be subject to is flesh
Meat or the damage of muscles and bones, if fallen under sick bed again, exacerbate the state of an illness of itself, it is also possible to which some patients are to treat
Period falls under sick bed, also carries medical care device on body when falling, such as breathing mask etc., if fallen, very
Probably due to medical care device comes off and causes patient to be in the boundary being in extreme danger.
Generally, patient is safely can to rest or receive on one's sick bed treatment, is on the one hand because uninterrupted
Ground has medical personnel and carries out medical and nursing work, or has families of patients and look after for a long time, even in night, it is also possible to arranges special
The nursing staff of door retains one's original salary patient is nursed, and shortens the unmanned nurse time of patient, on the other hand also in that some
Patient still has certain ability to act, to oneself having carried out self specification, reduces the probability to fall from the bed.But medical care
Personnel, families of patients or even the nursing staff that retains one's original salary are manually to nurse after all, and oneself also has the time had a meal, rested, can not be right
Patient carries out the uninterrupted, nurse of 24 hours, and therefore, patient still has certain unmanned nurse time, meanwhile, also have
Patient is to completely lose ability to act, for these patients, it is likely to once unintentionally turns over the hair for resulting in falling from bed event
It is raw.
In order to avoid the generation of patient's falling from bed event, in the prior art, hospital management side also takes much positive arrange
Apply, for example, transforming sick bed bed body, increase the height of guardrail, and set some geofences to set in sick bed bed body
Standby and emergence call equipment, to reduce the possibility of patient's falling from bed, the trigger device of falling from bed alarm is provided for patient, these transformations
Sick bed equipment afterwards reduces the generation of patient's falling from bed event to a certain extent.Meanwhile hospital management side also takes
Measure, such as increase and the interaction and communication of families of patients, to reduce the time of the unmanned nurse of patient.
But to make mechanism excessively simple for these existing hospital bed structural reforms, because patient's falling from bed duration intervals are very of short duration, on
The detection and warning device accuracy of detection stated be not high, detection efficiency is low, the increase of guardrail height and nurses the increase of time only
The probability of patient's falling from bed can be reduced, without being avoided that the event of falling from bed occurs, most importantly, is lacked in the prior art to patient
The fast reaction measure of falling from bed event and fast reaction equipment, fast reaction can not be carried out to patient's falling from bed event, can not be timely
Patient body is quickly supported, leads to not the ill effect for avoiding patient's falling from bed.
In order to overcome above-mentioned deficiency, the present invention has built a kind of blood purification multi-angle regulation operation table, can accurately, it is high
The falling from bed event of patient is detected to effect, can quickly be alarmed, additionally it is possible to patient is entered using some emergency reaction equipment
Row rescue, so as to effectively avoid patient from being injured by shock.
