Foot switch mistaken stepping prevention method and foot switch capable of preventing mistaken stepping

Abstract

The invention discloses a foot switch mistaken stepping prevention method and a foot switch capable of preventing mistaken stepping, a trigger device is arranged on the foot switch, the trigger device detects whether the foot of an operator reaches a trigger position, and when the trigger device detects that the foot of the operator does not reach the trigger position, the trigger device sends a signal to a control device, and the control device controls the foot switch not to work. Due to the fact that mistaken stepping is a casual behavior, an operator cannot be deliberately placed at the triggering position, the operator can consciously step to the triggering position as long as needed, and therefore according to the pedal switch mistaken stepping prevention method, the triggering device is arranged to detect whether the foot reaches the triggering position or not, the trigger device is in signal connection with the control device, so that when the feet of an operator do not enter a trigger position to trigger the trigger device but step on a pedal of the foot switch, the control device controls the foot switch not to work, and mistaken stepping and triggering are avoided.

Description

technical field [0001] The invention relates to the technical field of foot switches, in particular to a method for preventing false stepping on a foot switch and an anti-misstepping foot switch. Background technique [0002] The foot switch operates the on-off of the circuit or air circuit through the foot to cooperate with the hands to perform multi-task operations, and is widely used in medical equipment and processing equipment. [0003] The basic function of the foot switch is circuit or air circuit switch control. The more prominent problem in use is accidental activation caused by accidental stepping or object collision. [0004] Personal injuries and economic losses caused by wrong start of medical equipment and processing equipment have been reported at home and abroad. Safety foot switches with protective covers can reduce accidents caused by accidents, especially collisions, but cannot completely eliminate them. Accidents of accidentally stepping on occur, especi...

Problems solved by technology

[0003] The basic function of the foot switch is circuit or air circuit switch control. The more prominent problem in use is accidental activation caused by accidental stepping or object collision.

[0004] Personal injuries and economic losses caused by wrong start of medical equipment and processing equipment have been reported at home and abroad. Safety foot switches with protective covers can reduce accidents caused by accidents, especially collisions, but cannot completely eliminate them. Accidents of accidentally stepping on occur, especially in special environments that require a high degree of concentration. For example, in the process of laser surgery, the doctor's hands manipulate the endoscope to find lesions and inject drugs, and the foot stays above the foot switch to start the laser at the right time During the operation, the medical staff are highly concentrated, and inadvertent foot touches will mistakenly activate the laser beam, resulting in personal injury

[0005] Similarly, the unexpected start-up of large-scale mechanical processing equipment will not only cause economic losses but may also cause accidental injuries
