Description
The present invention be Application No. 201610349781.4, the applying date be on May 24th, 2016, it is entitled " a kind of
The divisional application of the patent of Ultrasonography examination couch ".
Technical field
The present invention relates to source of early warning field, more particularly to a kind of Ultrasonography operation table.
Background technology
For to be treated in hospital department etc. or receive the patient for the treatment of, sick bed is their main activities field
Institute, hospital management side and families of patients wish that patient can restfully couch and rest or receive treatment on one's sick bed, ensure patient
Treatment phase and convalescence can normally be tided on one's sick bed, with wait terminate treatment date to facing.
However, if patient falls from sick bed accidentally, can not estimate to the injury that patient brings, because
The state of an illness of some patients in itself is easy to because fall and bring secondary injury, such as some patients, itself be subject to be muscle 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 during treatment
Fall under sick bed, also carry medical care device on body when falling, such as breathing mask etc., if fallen, be likely to
Patient is caused to be in the boundary being in extreme danger because medical care device comes off.
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.
Therefore, it is necessary to which a kind of new technical scheme with hospital bed fall arrest, can accurately and efficiently detect disease
The falling from bed event of people, can quickly be alarmed, additionally it is possible to patient be given first aid to using some emergency reaction equipment, so as to have
Effect avoids patient from being improved the intelligent level of sick bed by injury is hit, maintain the medical care effect of hospital.
The content of the invention
In order to solve the above problems, the invention provides a kind of Ultrasonography operation table, by transforming existing hospital's disease
Bed bed body, weight detection equipment, image detecting apparatus and ray detector pair are introduced in existing hospital bed bed body
Patient's falling from bed event carries out accurate judgement, introduces some sources of early warning and is alarmed accordingly, it is often more important that, also introduce
Targetedly urgent rescue equipment is effectively supported to the patient body to fall, so as to improve the security performance of sick bed.
