Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to an orthopedic operation anti-falling bed.
Background
The hospital bed can also be called a medical bed, a nursing bed and the like, is used when patients are in rest, and is mainly used in various hospitals, health hospitals, community health service centers and the like.
Sickbeds are classified into ABS sickbeds, all-stainless steel sickbeds, semi-stainless steel sickbeds, all-steel plastic-sprayed sickbeds and the like according to the material. The hospital beds can be classified into medical hospital beds and household hospital beds according to purposes. Sickbeds are classified into electric sickbeds and manual sickbeds according to functions, wherein the electric sickbeds can be classified into five-function electric sickbeds, three-function electric sickbeds and the like, and the manual sickbeds can be classified into double-rocking sickbeds, single-rocking sickbeds and flat-plate sickbeds.
For patients waiting for treatment or receiving treatment in hospital departments, hospital beds are the main activity places of the patients, and hospital management parties and patient families hope that the patients can lie stably on the hospital beds for rest or receive treatment, so that the patients can normally live through a treatment period and a rehabilitation period on the hospital beds to wait for the arrival of treatment ending dates.
For example, after the orthopedic surgery, a patient needs to lie in bed for a long time to rest, if the patient falls from a sickbed carelessly, the injury to the patient cannot be measured, the condition of the patient is aggravated, the secondary injury occurs at the bone surgery part, and the operation needs to be performed again; it is also possible that some patients fall under the bed during observation, while in case of a fall they are physically carrying a medical device, such as a breathing mask, etc., and if they fall they are likely to be in an extremely dangerous situation because the medical device falls off.
Generally, a patient can have a rest or receive treatment safely on a hospital bed, on one hand, medical staff can carry out medical work uninterruptedly, or family members of the patient can take care of the patient for a long time, even at night, special nursing staff can be arranged to take care of the patient, unattended time of the patient is shortened, on the other hand, some patients have certain mobility, self-regulation is carried out on the patients, and probability of falling from the bed is reduced. However, medical staff, patient family members and even paid nursing staff are not only manually nursed but also have the time of eating and resting, and the patients cannot be cared for 24 hours without interruption, so that the patients still have certain unattended time, and some patients have complete incapacity of moving, and the patients are likely to have a fall-off event due to an unintentional turn-over.
In order to avoid the occurrence of a patient falling from the bed, in the prior art, a hospital management party also takes a lot of active measures, for example, a border-crossing alarm device and an emergency call device are arranged on a bed body of a hospital bed to reduce the possibility of falling from the bed of the patient, a triggering device, a sensing device, a judging device, a protecting device and the like for falling from the bed and alarming are arranged on the bed body, and the occurrence of the patient falling from the bed is reduced to a certain extent by the modified hospital bed device. Meanwhile, the hospital management side also takes measures, such as increasing interaction and communication with the family members of the patients, so as to reduce the time that the patients are unattended.
However, the transformation mechanism of the existing sickbed bodies is too complex, because the patient falls down to the bed and the interval is short, the sensing device judging device can hardly make judgment in a very short time and control the protection device to protect the patient, and most importantly, the bed body provided with the sensing device, the judging device and the protection device is complex in structure and extremely high in cost.
Therefore, a new technical scheme for preventing falling of hospital bed is needed, which can effectively protect patients and is convenient for popularization with low manufacturing cost, so as to effectively avoid the patients from being injured by collision.
