Description

This utility model relates to weight scales, and in particular to types of ambulatory mobile weight scales that enable fast and accurate weighing of bedridden patients or patients with disorientation (disorientation) or confusion.

The dosage of many drugs depends on the weight of the patient. If the wrong dose is given, the efficacy of the drug is reduced and the risk of side effects is increased.

At admission, many patients are unable to support their own weight due to unconsciousness or suspected injury, especially back injury, neck injury, or leg injury. Furthermore, if a patient is admitted with chest pain or dyspnea, the hospital's allowance for such patients is to remain in a lying or sitting position. Such patients cannot be weighed with conventional scales, because conventional scales require the patient to stand. Whilst weighing devices such as hoists are available in the hospital, these involve placing the patient in the hoist and lifting the patient from the bed/stretcher (wheeled stretcher) to weigh. This is time consuming, requires the patient to be hung, and has consequent safety issues, for example the hoist may fall if not properly used. Alternatively, a floor scale can be used that weighs the patient and stretcher together. Floor scales tend to be quite heavy and are therefore not portable and require sufficient size to accommodate a stretcher. Both of the methods described above require a significant amount of space and are often very expensive in hospital emergency areas.

If the patient is bedridden for an extended period of time, the medical staff (workers) must regularly weigh the patient in order to estimate the medication to be administered. In an emergency, the patient may be unconscious or injured, impeding standing and making it impossible for the patient to stand for weighing.

For example, if the patient is a child, or if the patient is confused, drunk, and/or uncooperative, and the patient dislikes to remain still during the weighing procedure, Is difficult to measure.

In such a situation, the weighing operation may be very inconvenient and may require the assistance of a large number of medical personnel. In addition, if the patient is unable to maintain an immobile posture, the risk of weighing errors increases, which can cause errors in the amount of drug administered.
