Non-contact input keyboard

Abstract

The invention discloses a non-contact input keyboard which comprises an input detection module, an STM32F407 single chip microcomputer, an LCD display screen and an HC05 Bluetooth module. According tothe invention, an induction coil is arranged on a capacitor plate; through input detection of a first chip and a second chip is carried out, a gesture instruction of a doctor is received and converted into digital information; the STM32F407 single-chip microcomputer is adopted for real-time data processing, the processed information is in Bluetooth connection with a terminal of an external medical instrument through the HC05 Bluetooth module so as to control the medical instrument to carry out surgical operation on a patient, and a control instruction is displayed to a doctor at any time through an LCD display screen. According to the invention, a doctor only needs to place a hand at the induction coil position arranged on the capacitor plate, sends out different instructions through gesture conversion of the doctor, and sends the instructions to the terminal of the medical instrument through the Bluetooth, so that surgical operations with different programs are implemented. The induction coil arranged on the capacitance plate can receive static gestures or dynamic gestures of doctors, has the advantages of being easy to manufacture and convenient to use, and meets the requirementof medical treatment for non-contact input.

Description

technical field [0001] The invention relates to the field of sensor technology, and is aimed at a sensor device for which a doctor cannot directly touch an instrument keyboard by hand during an operation, in particular a non-contact input keyboard. Background technique [0002] With the continuous development of medical technology and the continuous improvement of the level of medical operations, it is inevitable for doctors to perform operations with advanced medical equipment. The problem is that doctors during operations need to pay great attention to the cleaning of their hands to prevent the infection of the wound by microorganisms. If the application of sensor technology can be used to design a low-power, sensitive and accurate non-contact input keyboard at the front of the medical device, the doctor's gestures will issue instructions, and the instructions will be received, edited and passed by the input keyboard in a contactless manner. Bluetooth wireless transmission...

The problem is that doctors during operations need to pay great attention to the cleaning of their hands to prevent the infection of the wound by microorganisms. If the application of sensor technology can be used to design a low-power, sensitive and accurate non-contact input keyboard at the front of the medical device, the doctor's gestures will issue instructions, and the instructions will be received, edited and passed by the input keyboard in a contactless manner. Bluetooth wirelessly sends to medical devices, and it will be very necessary to finally control the medical devices to complete the operation
