Description

Wheelchair weighing scale with limiting function

Technical Field

The utility model relates to the technical field of medical appliances, in particular to wheelchair personal weighing scale with limit function.

Background

The wheelchair weighing scale is generally mainly composed of a bearing system (such as a scale pan and a scale body), a force transmission conversion system (such as a lever force transmission system and a sensor) and a value indicating system (such as a dial and an electronic display instrument), and is generally used for weighing the old, the patient or the disabled who are inconvenient to move when sitting on a wheelchair. When the human body is on the scale, the measured data can be read out from the electronic display instrument. In the practical utility model, when weighing, patients with severe symptoms such as hemodialysis generally need medical staff or family members to push the wheelchair weighing scale on the wheelchair for weighing. During the weighing process, the medical personnel or family members will not contact the wheelchair. The inclination or movement of the critically ill patient can cause the wheelchair to slide or topple, and further cause unsafe events such as falling of the critically ill patient.

For example: a comparison document I (a Chinese patent with the publication number of CN 216717580U) discloses a wheelchair weighing scale, which comprises a first weighing seat, a telescopic rod, a second weighing seat, a processor, a display, a zero clearing key, an on-off key, a first foot pad, a first signal wire, a second foot pad, a second signal wire, a third signal wire, a first weighing sensor, a second weighing sensor and an accommodating groove; the processor is arranged in the first weighing seat, the upper surface of the first weighing seat is provided with an accommodating groove, a display is arranged in the accommodating groove, the first weighing seat is provided with a zero clearing key and an on-off key, each corner of the first weighing seat is provided with a first foot pad, the bottom of the first foot pad is provided with a first weighing sensor, the first weighing sensor is connected with the processor through a first signal line, the processor is connected with the display through a third signal line, the lower surface of the first weighing seat is fixedly provided with a telescopic rod, and a wire passing channel extending along the axis direction of the telescopic rod is arranged in the telescopic rod; the other end of the telescopic rod is fixed with the lower surface of the second scale seat, a second foot pad is arranged at each corner of the second scale seat, a second weighing sensor is arranged at the bottom of the second foot pad and connected with one end of a second signal wire, the other end of the second signal wire penetrates through a wire passing channel in the telescopic rod and then is connected with the processor, and the upper surface of the second scale seat is flush with the upper surface of the first scale seat.

Although above-mentioned comparison file is convenient for accomodate, in the actual operation in-process, its first title seat is higher, and inconvenient patient goes up first title seat, and simultaneously, measures such as protection are not established to first title seat, lead to the wheelchair to slide or empty easily, and then the unsafe incident such as the severe patient tumbles that easily leads to takes place.

A second comparison document (chinese patent publication No. CN 204740063U) discloses an electronic scale convenient for wheelchair weighing, which includes a scale body, a sensor arranged inside the scale body, an electronic display arranged outside the scale body, two inclined plates and an armrest device, wherein the inclined plates are respectively arranged at the left and right sides of the scale body, and one end of each inclined plate is connected with the scale body while the other end thereof rotates around the left/right side edges of the scale body, and is attached to the upper surface of the scale body or contacts with the ground; the armrest device is arranged on the rear side edge of the scale body, and the electronic display is arranged above the armrest device and used for a weigher to check measurement data.

Although the above-mentioned comparison document enables the person of weighing to stabilize the body shape through handrail setting, has solved the drawback in comparison document one, the serious disease patient such as hemodialysis generally does not have strength to grasp, and this comparison document in actual use can not make this kind of serious patient carry out the effect of stabilizing the body shape.

Therefore, the wheelchair weighing scale with the limiting function meets the requirement.
