Description
Technical field
The invention belongs to technical field of medical equipment, and in particular to a kind of anti-falling from bed of bone surgery.
Background technology
Sick bed is alternatively referred to as medical bed, care bed etc., is the sick bed that patient uses in recuperation, and main use occasion has respectively
Large hospital, commune hospital, community medical service center etc..
Sick bed can be divided into ABS sick beds, all steel sick bed, semi-stainless steel sick bed, all-steel plastic-spraying sick bed by material point
Deng.Sick bed can be divided into medical hospital bed, household sick bed by purposes point.Sick bed can be divided into electric hospital bed and manual disease by function point
Bed, wherein electric hospital bed and can be divided into that five-function is electric hospital bed and three functional electric sick beds etc., manual sick bed can be divided into again pair to be shaken
Sick bed singly shakes sick bed, tablet sick bed.
For to be treated in hospital department etc. or reception treatment patient, sick bed is their main activities field
Institute, hospital management side and families of patients wish that patient can restfully lie down 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 for terminate treatment date to facing.
After bone surgery, patient needs long-time laid up, if patient falls from sick bed accidentally, gives patient
The injury brought can not be estimated, and the state of an illness of itself is exacerbated, and lead to occur secondary damage at osseous surgery, need hand again
Art；It is also possible to some patients are fallen during observation under sick bed, medical care device, example are also carried on body when falling
Such as breathing mask, if fallen, probably because medical care device falls off and patient is caused to be in the boundary being in extreme danger.
Under normal circumstances, patient is safely can to rest or receive on one's sick bed treatment, is on the one hand because uninterrupted
Ground has medical staff and carries out medical and nursing work, or has families of patients and look after for a long time, even if at night, it is also possible to arrange special
The nursing staff of door retains one's original salary and is nursed to patient, 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, oneself also has the time had a meal, rested, can not be right
Patient carries out uninterrupted, 24 hours nurses, and therefore, patient still has certain unmanned nurse time, meanwhile, more also
Patient is to completely lose ability to act, for these patients, it is likely to once unintentionally turn 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
It applies, for example, some geofence equipment and emergence call equipment are arranged in sick bed bed body, to reduce the possibility of patient's falling from bed
Property, trigger device, sensing device, judgment means and the protective device etc. that falling from bed is alarmed are set in bed body, these are improved
Sick bed equipment reduces the generation of patient's falling from bed event to a certain extent.Meanwhile hospital management side also takes some measures,
Such as the interaction and communication of increase and families of patients, to reduce the time of the unmanned nurse of patient.
But to make mechanism excessively complicated for these existing hospital bed structural reforms, and since patient's falling from bed duration intervals are very of short duration, sense
It is difficult to be judged in very short time and control protective unit protects patient to answer device judgment means, most importantly,
The bed structure that sensing device, judgment means and protective device is arranged is complicated, and cost is high.
Therefore, it is necessary to a kind of new technical solutions with hospital bed fall arrest, can effectively be protected to patient, together
When manufacturing cost it is low convenient for universal bed body, avoid patient from being injured by hitting with effect.
Invention content
