Problems solved by technology

Large-scale equipment is expensive and has a large operating space, and it needs to be equipped with professionals. It is difficult to popularize most dry eye patients
When doctors use known large-scale intense pulsed light equipment, they usually need to conduct experimental treatment in the preauricular area with lower energy, and observe the immediate response of the skin, and adjust relevant parameters according to the patient's tolerance and comfort. The treatment process inevitably increases the medical risk accordingly, as well as the clinical difficulty for novice doctors

Embodiment 1

[0039] refer to figure 1, provides a hand-held phototherapy device for dry eye syndrome, including a housing 1, the housing 1 is provided with a light outlet 10, and a pulsed light generating device 22 is provided inside the housing 1 close to the light outlet 10, and the housing 1 1 is also provided with a controller 20 for driving the pulsed light generating device 22 and a power supply 21 for powering the controller 20 and the pulsed light generating device 22. The controller 20 includes a light control terminal 4 and a power receiving terminal 9. The light control terminal 4 contains a control circuit, the pulsed light generating device 22 is coupled to the light control terminal 4 through the control circuit, and the power supply 21 is coupled to the power receiving terminal 9; the pulsed light generating device 22 is controlled by the light control terminal 4 to generate light A pulse train with an energy density of 1 J / cm² to 25 J / cm², said pulse train consisting of a p...

Embodiment 2

[0080] A phototherapy method for dry eye syndrome is provided, which is applied to any one of the hand-held phototherapy equipment for dry eye syndrome in the first embodiment above, and specifically includes the following steps:

[0081] The intelligent detection device receives the reflected light reflected from the skin, generates a Lab value according to the light intensity and spectral distribution of the reflected light, and sends the Lab value as a skin detection signal to the skin detection signal receiving end;

[0082] After the skin detection signal receiving end receives the skin detection signal, the controller judges whether it touches the skin according to the preset value. If it touches the skin, it classifies the skin type according to the Fitzpatrick skin classification system;

[0083] According to the classification category, the pulsed light generation device generates short pulses at intervals of 0.1ms to 50ms through the control circuit, so that it forms ...

Abstract

The invention discloses a hand-held xerophthalmia phototherapy device and a xerophthalmia phototherapy method. The hand-held xerophthalmia phototherapy device comprises a shell, a light emitting portis formed in the shell, and a pulse light generating device is arranged at the position, near the light emitting port, inside the shell; a controller for driving the pulse light generating device anda power source for supplying power to the controller and the pulse light generating device are further arranged in the shell; the controller includes a light control end and an electric energy receiving end, the light control end includes a control circuit, the pulse light generating device is coupled with the light control end through the control circuit, and the power source is coupled with theelectric energy receiving end; the pulse light generating device generates a pulse string with a light energy density of 1 J / cm<2> to 25 J / cm<2> through the control circuit connected to the light control end, the pulse string is composed of a plurality of short pulses, each short pulse is intermittently generated at time intervals of 0.1 ms to 50 ms; and a light filter module is arranged between the pulse light generating device and the light emitting port, the light filter module is used for generating a spectrum capable of effectively treating xerophthalmia, and the spectrum includes a yellow red light spectrum and a near infrared light spectrum. The hand-held xerophthalmia phototherapy device can produce a high energy density pulse that meets xerophthalmia phototherapy for a user to safely complete xerophthalmia improvement and treatment operations.

Description

technical field [0001] The invention relates to the field of ophthalmic medical technology, in particular to a hand-held phototherapy device for dry eye syndrome and a phototherapy method for dry eye syndrome. Background technique [0002] Dry eye syndrome refers to the general term for various diseases caused by abnormal tear quality or quantity or dynamics caused by any reason, resulting in decreased tear film stability, accompanied by ocular discomfort and / or ocular surface tissue lesions. Also known as keratoconjunctival sicca. Common symptoms include dry eyes, easy fatigue, itchy eyes, foreign body sensation, burning sensation, sticky secretions, fear of wind, photophobia, and sensitivity to external stimuli; sometimes the eyes are too dry, and there is basically insufficient tear fluid, which stimulates the reflex In severe cases, the eyes will be red and swollen, congested, keratinized, and the corneal epithelium is broken and there are filaments adhered. This kind...
