An automated tonometer is an advanced medical device used to measure a person's intraocular pressure either non-contact or contact to help diagnose and monitor diseases such as glaucoma. Below is a brief introduction to automated tonometers and an analysis of why touchscreens are competent interactive interfaces for automated tonometer instruments:
There are two main types of tonometers: non-contact and contact:
Non-contact tonometer: Utilizes optical measurement technology to obtain intraocular pressure data contactlessly by scanning the anterior surface of the cornea. When used, it will produce a gentle jet of air waves, through the air waves hit the cornea and then reflected back to the pressure value, so as to determine the level of intraocular pressure. It is convenient, safe and hygienic, but relatively expensive.
Contact tonometer: through the pressure needle directly in contact with the patient's eye, through the depth of the cornea after the application of pressure to measure the patient's intraocular pressure value. This method measures accurately and has clinical accuracy, and is currently the most accurate measurement method. However, improper use can easily cause infection, and the patient must be ordered with anesthetic, which has certain side effects on the body.
Touch screen as the interactive interface of the automatic tonometer has the following advantages:
Intuitive and easy to use: touch screen interfaces are usually designed to be intuitive and easy to understand, allowing users to complete the IOP measurement process through simple touch operations without the need for complex training or guidance.
Improved measurement efficiency: Touchscreens improve measurement efficiency by quickly responding to user commands and reducing waiting time during the measurement process.
Reduces cross-contamination: Using a touch screen in an automated tonometer avoids the risk of cross-contamination that may be associated with traditional buttons or knobs, especially during epidemics such as pinkeye, making the use of touch screens safer.
Enhanced user experience: Touch screen interfaces often have user-friendly graphical interfaces and animations, which can provide a more pleasant measurement experience for the user. In addition, touchscreens can be personalized to meet the needs of different users.
In summary, the touch screen is capable of being the interactive interface of the tonometer instrument due to its advantages of being intuitive and easy to use, improving measurement efficiency, reducing cross-infection, and enhancing user experience.
