The invention relates to a protective warning device, in particular to a protective warning device for protecting a patient from falling or arbitrarily leaving the bed.

Referring to Annex 1-3, according to the statistics of the Health Department of the Executive Yuan and the Hospital Appraisal and Medical Quality Policy Committee, the proportion of accidents in medical institutions has increased year by year. Among them, the fall event in 201115207 For the event, the number of incidents was reported several times in the year, and the most common fall event was due to the shift of the bed and bed. If the bed is strengthened, it will help reduce the chance of a fall event.

Referring to FIG. 1, the warning device 1 of the Republic of China Patent No. M400627 is mainly installed on a wall surface adjacent to one end of a hospital bed 2, and has an infrared light sensing unit 11 that emits infrared rays in the direction of the straight line L, and An alert unit 12 that generates a warning signal. Thereby, when the patient sits up, the infrared rays may cause a change in the amount of reflection due to being projected on the patient, thereby triggering the warning unit 12 to generate a warning message to remind the family or the medical staff.

However, as shown in the third line of the last page on page 6 of the M400627 case, the angle of travel of the infrared rays is almost linear, so when the patient turns over When the body is not in the center of the hospital bed 2, and moves to the side of the hospital bed 2, it will deviate from the path of the infrared rays traveling, and there is a feeling of failure, which not only easily forms a dead angle of sensing, but also fails to achieve an effective protective effect. And the warning device 1 is fixed on the wall surface of the ward, and in addition to being difficult to disassemble and install, and in the case where the mobility is insufficient and cannot be selectively installed, if the warning device 1 is installed on the wall surface of all the beds 2, There are disadvantages such as high cost, and the fact that the patient does not need protection and is ineffective, which does not meet the actual use requirements.

In addition, since the foregoing warning device 1 can only generate a warning message by sound, without the function of remote message notification or immediate monitoring from the video, if there is no medical staff or family members at the scene, it is easy to miss the warning message and lose the warning. effect.

Accordingly, it is an object of the present invention to provide a guard alert device that can enhance the sensing range and enhance the protective effect of the hospital bed.

Therefore, the bed has a front surface supporting a human body, a front end portion adjacent to a head of the human body, and a rear end portion adjacent to a foot portion of the human body. The protective warning device of the present invention comprises a vehicle and a light sensor. Unit, and an alarm unit. The vehicle is placed in the hospital bed. The light sensing unit is mounted on the carrier and forms a height difference with the bed surface of the hospital bed, and receives light in a sensing range not longer than the length of the short side of the hospital bed in a short side direction of the hospital bed. The alarm unit is electrically connected to the light sensing unit, and generates a warning message when the light within the sensing range is mutated.

The invention has the beneficial effects of using the light along the short side of the bed to limit the sensing range to the short side of the bed, which can not only make The sensing range extends to the entire bed to reduce dead angles and enhances the protective effect during sensing.
