Description

Temperature control intraocular pressure induction eye heating electrothermal film with intraocular pressure sensor

Technical Field

The invention relates to a temperature-controlled electrothermal film with a pressure sensor, in particular to a pressure-controlled electrothermal film for treating functional meibomian gland dysfunction.

Background

Dry eye may result from a condition known as Meibomian Gland Dysfunction (MGD), which is a chronic abnormality of meibomian gland function characterized by obstruction of the meibomian gland ducts or abnormalities in the amount or amount of secreted material. Known Meibomian Gland Dysfunction (MGD) treatments typically apply significant heat to melt loose or soften obstructions or occlusions in the meibomian glands.

One type of prior art applicator treats dry eye by monitoring and adjusting the electrical signal using an electrical signal requiring the use of a thermocouple and a complex feedback control system to maintain the heat between 43-47 c for 1-10 minutes to apply heat to the eye. While such heaters apply pressure on the eye using screws to adjust the pressure on the eye, since such heater treatment requires adjustment of the pressure by means of a threaded shaft or screw, and requires the use of an electrical signal from a thermocouple to control the elevated heat, and furthermore requires independent control of the heating temperature and treatment time, precise thermal adjustment of the actual temperature and pressure on the eye must be given and monitored by a medical physician or technician to avoid burning the eyelids or damaging the eye itself.

The prior art also has another heater that uses a battery operated surgical heater that heats a compression similar to an eye mask for a post-ophthalmic patient, the heater being strapped to a surgical compressor that applies heat to the patient's eye orbit, since the heater is one of molded plastic that is not integral with the compressor, two battery operated, three using wiring for the heating element, four heats the compression rather than the eyelid, which results in an uncomfortable, uncontrolled heat source whose treatment process does not carefully control the temperature to the eyelid itself. Due to these factors, the treatment time, the actual temperature and the pressure on the eye must also be administered and monitored by a medical physician or technician to avoid burning the eyelids or damaging the eye itself.

In addition, most human eyes can cause intraocular pressure to rise when being heated for a long time, and when the intraocular pressure exceeds a certain millimeter mercury, injury can be caused.

Therefore, it is urgent to provide an electric heating film which has accurate control precision, can flexibly control the heating temperature, is adaptive to the intraocular pressure of a user and gives an alarm when the intraocular pressure is increased.
