Description
Technical field
The present invention relates to medical care equipment field, particularly relate to a kind of care bed for department of cardiology.
Background technology
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.
Accordingly, it would be desirable to the technical scheme of a kind of new hospital bed fall arrest, it is possible to accurately and efficiently
Detect the pendant bed event of patient, it is possible to quickly report to the police, additionally it is possible to use some emergency reactions to set
For patient is given first aid to, thus it is prevented effectively from patient and is injured by shock.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of care bed for department of cardiology, in existing hospital
Introduce weight detection equipment, image detecting apparatus and ray detector in sick bed bed body patient is fallen
Bed event accurately judges, introduces some sources of early warning and reports to the police accordingly, it is often more important that,
The patient body fallen effectively is supported by the urgent rescue equipment targetedly that also introduces, it is to avoid
Patient because pendant bed and by actual bodily harm, thus indirectly maintain the therapeutic effect of hospital.

Armarium improves constantly the primary condition of medical science level, is also up-to-dateness
Important symbol, armarium has become a key areas of modern medical service.The development of medical treatment is the biggest
Depending on the development of instrument in degree, even in medical industry develops, its breakthrough bottleneck also plays
Conclusive effect.
Medical apparatus and instruments refer to be used alone or in combination the instrument in human body, equipment, utensil, material or
Other article of person, also include required software.For body surface and internal therapeutic effect it is not
Obtained by the means of pharmacology, immunology or metabolism, but medical device product serves one
Fixed assosting effect.During use, it is intended to reach following expection purpose: prevention of disease, examine
Break, treat, guard, alleviate；To damage or the diagnosis of deformity, treat, guard, alleviate, mend
Repay；To dissecting or the research of physiological process, substituting, regulate；Gestation controls.
Armarium can be divided into 10 classes: ward nursing equipment (sick bed, go-cart, oxygen cylinder, gastric lavage
Machine, needleless injector etc.)；Surgical apparatus (operation table, luminaire, operating theater instruments and various,
Frame, stool, cabinet, also include microsurgical equipment)；Radiotherapy equipment (contact apparatus, shallow-layer
Therapy apparatus, degree of depth therapy apparatus, accelerator, 60 Co60 radiotherapy unit 60s, radium or 137 caesium intracavitary therapies and after fill
Device treatment etc.)；Nuclear medicine treatments equipment-Therapeutic Method has internal-radiation therapy, application therapy and colloid
Treat three kinds；Physics and chemistry equipment (can be generally divided into phototherapy commercial affairs, electrotherapy apparatus, ultrasonic therapeutic and sulfur

Treatment equipment, the most also can be separately divided into a class.
Sick bed is armarium most basic in hospital, modal, the medical time of most patients and
The nurse time tides over the most on one's sick bed, but, due to reason and the unmanned nursing of sick bed structure itself
The existence of time, patient falls an event and happens occasionally, and causes bigger injury to patient, except band
Serve outside the pain of injury on shock, also likely expand the state of an illness of patient, to the recovery of patient and
Treatment adversely affects.
Currently, hospital management side the most actively take some measures patient is fallen an event carry out prevention and
Avoid, such as, reinforce bed body, increase source of early warning, reduce the unmanned nursing time, but, on the one hand
These measures and equipment are excessively simple, and detection and early warning are inefficient, on the other hand, lack patient
Hold up the urgent rescue equipment of patient body during pendant bed, fall an event also cannot keep away even if having detected patient
Exempt from patient and fall the consequence that bed causes, do not provide any help in practice for patient.
In order to overcome above-mentioned deficiency, the present invention has built a kind of care bed for department of cardiology, utilizes existing doctor
Institute's sick bed bed body, carries out structure of modification and upgrading to it, adds various detection equipment and source of early warning
Patient falls an event accurately identify, particularly critical, also add effective emergency reaction
Equipment carries out urgent rescue when patient falls bed, thus avoids the secondary that pendant bed event causes to patient
Injury occurs.
