Description

Multi-modal weight scale

The present invention relates to a weight scale for measuring body weight, in particular a weight scale that can change shape according to different situations, allowing the user to measure weight in a sitting, lying or standing position, and is convenient to store and carry.

Weight is a basic physiological condition that must be assessed when visiting a hospital. Weight data is also an important indicator for assessing the patient's medication dosage and nutritional status. If the error in measuring weight is too large, it will lead to inaccurate medication dosage, which may cause the accumulation of drugs in the patient's body and increase the probability of side effects. If the wrong anesthesia dose is given during surgery, severe cases may even endanger life. In addition, cancer patients will have weight differences during cancer, chemotherapy, radiotherapy, etc., so it is necessary to constantly assess weight changes, because weight loss will not only affect the treatment effect, but also directly affect the prognosis of resistance and survival.

Commonly used weight measurement equipment in hospitals include upright height and weight scales, bed scales, bed hanging scales, sitting scales and floor scales. These weight measurement equipment have their own applicable scenarios and objects.

Generally, upright height and weight scales available on the market have almost no handrails for support. Elderly people with slow movements, insufficient lower limb muscle endurance, and unstable gait are more likely to lose their balance and fall when stepping on the height and weight scale.

Although bed scales, bed hanging scales, sitting scales and floor scales solve the problem of the elderly using upright height and weight scales, for bedridden patients, in the process of moving the patient from the bed or wheelchair to the bed hanging scale, bed scale or sitting scale for weight measurement, in addition to increasing the labor burden of medical staff, it may also cause secondary injuries to patients and occupational injuries to medical staff.

Bed scales, bed hanging scales, sitting scales and floor scales are special measuring equipment, and they are all relatively expensive. If every ward area is fully equipped with these devices, it will be a considerable burden on the hospital budget. On the other hand, bed hanging scales, sitting scales or floor scales are relatively large in size and require a certain amount of space to place, which will also limit or affect the placement space of other equipment in the same ward area.

In the patent application No. 082208805 of the Republic of China, the inventor proposed a "body weight device that can be used in different standing, sitting and lying postures", but it still has many shortcomings. For example, when measuring body weight in different postures, it is necessary to install or remove additional components (chair board, bed frame), and the measurement results must deduct the weight of the components installed for different postures. It is inconvenient to use and may cause measurement errors. In addition, the storage and preservation of components is also a problem for medical staff and hospitals.

Therefore, there is a great need for a weight scale that can adapt to different situations, allowing users to measure their weight in different postures such as sitting, lying or standing, and can be folded into a small size for easy storage and portability, and does not require the installation or removal of additional components.

The purpose of the present invention is to provide a weight scale that can change shape according to different situations, allowing users to measure their weight in different postures such as sitting, lying or standing.

Another purpose of the present invention is to provide a multi-modal weight scale that provides armrest support when the user measures weight in a sitting or standing position to prevent the user from falling due to instability.

Another object of the present invention is to provide a multi-form weight scale that can be folded into a small size for easy storage and portability.

To achieve the above-mentioned purpose, the present invention provides a multi-form weight scale, comprising: a load-bearing platform, the load-bearing platform comprising a plurality of plates, the plates being in a hinged relationship, and the shape of the load-bearing platform can be changed to allow the user to sit, lie or stand on the load-bearing platform; a base, equipped with at least one weight sensor for obtaining measurement results; a support structure, comprising a first support part and a second support part, the first support part and the second support part being respectively connected to the load-bearing platform; On the two opposite sides of the load-bearing platform and the base, the first support part and the second support part each include an upper support member and a lower support member, and the load-bearing platform and the upper support members, the upper support members and the lower support members, and the lower support members and the base are all in a pivotal relationship; a telescopic rod, one end of which is pivoted to the base and the other end is pivoted to the support structure on the opposite side, is used to drive the support structure to expand or fold, and change the distance between the load-bearing platform and the base.

Preferably, the plates include: a first plate and two second plates, the two opposite sides of the first plate are respectively pivoted to one side of the two second plates, and the second plates can be horizontal, vertical and/or overlapped relative to the first plates. The plates can further include two third plates, one side of the two third plates is respectively pivoted to the other side of the two second plates relative to the first plates, and the third plates can be horizontal, vertical and/or overlapped relative to the second plates.

Preferably, the multi-modal weight scale further includes a wheel seat disposed on the base, and the wheel seat is equipped with a plurality of rollers.

Preferably, the multi-modal weight scale also includes a display device, which includes a display and a connector, and the two opposite sides of the connector are respectively connected to the wheel base and the display, and the display is used to receive and display the measurement results.

Preferably, the base includes a first base rod, a second base rod and a connecting rod between the first base rod and the second base rod.

Preferably, the telescopic rod is connected between the first base rod or the second base rod and the lower support member on the opposite side.

Preferably, the base includes a handle.

Preferably, the telescopic rod is a pneumatic rod, a hydraulic rod or a screw rod.

Preferably, the multi-modal weight scale also includes a transmission unit to transmit the measurement results to other devices in a wired or wireless manner.

The multi-morphological weight scale provided by the present invention can change its shape according to different situations, allowing users to measure their weight in different postures such as sitting, lying or standing, and providing users with support and auxiliary handrails when measuring their weight, thereby reducing the probability of falling. For hospitals, there is no need to purchase bed scales, sitting scales, upright weight scales and other equipment at the same time, and it can also avoid limiting the placement space of other equipment in the same ward area. In addition, the multi-morphological weight scale of the present invention can be folded into a small size, which is convenient for storage and mobile carrying, reducing the waste of space.

In summary, the present invention provides an innovative multi-position weight scale that can change its position according to different situations, allowing users to measure their weight in different positions such as sitting, lying or standing. For bedridden patients, the weight measurement can be completed without changing the bed or moving the patient. The elderly and the disabled can measure their weight in a sitting or lying position, and ordinary people can also measure their weight in a standing position. When measuring weight in a sitting or standing position, handrails are provided to support and assist, preventing the user from falling due to instability, thereby improving the work efficiency of medical staff and reducing the labor burden and psychological pressure of the patient's family and caregivers. For hospitals, there is no need to spend money on purchasing bed scales, sitting scales, upright weight scales and other equipment at the same time, and it can also avoid limiting the placement space of other equipment in the same ward area. In addition, the multi-form weight scale of the present invention can be folded into a small size, which is convenient for storage and mobile carrying, reducing the waste of space.

The above-mentioned embodiments only express the preferred implementation of the present invention, and the description is relatively specific and detailed, but it should not be understood as limiting the patent scope of the present invention. It should be pointed out that ordinary technicians in this field can make several changes and improvements without departing from the concept of the present invention, which are all within the protection scope of the present invention.
