Problems solved by technology

With age, the toxic and side effects of drugs will become more obvious; Surgical treatment: The operation is traumatic, the process is more painful, and the postoperative care is more cumbersome; there may be sequelae such as dry nose, nasal pain, hyposmia or loss of smell, three years. The probability of recurrence is about 40%, and the probability of recurrence after five years is even greater; desensitization therapy: due to the need for continuous injections, complications of multiple dermatitis are prone to occur; treatment costs are high, and the course of treatment is long. For three years, patients often cannot adhere to complete the full course of treatment

Abstract

The invention discloses a rhinitis phototherapy instrument including a power supply battery, a start switch, a single-chip microprocessor and two LEDs. The power supply battery is connected with the start switch and provides power supply. The rhinitis phototherapy instrument also includes a differentiating circuit, a self-locking electronic switch, a voltage reducing circuit and a constant current drive circuit. The output terminal of the differentiating circuit is connected with a triggering terminal of the self-locking electronic switch. The output terminal of the self-locking electronic switch is connected with the voltage reducing circuit and a working power terminal of the constant current drive circuit. The output terminal of the voltage reducing circuit is connected with a power port of the single-chip microprocessor. The single-chip microprocessor outputs self-locking maintaining signals and LED drive signals separately. The self-locking maintaining signals are also connected with the triggering terminal of the self-locking electronic switch. The LED drive signals are connected with a drive input terminal of the constant current drive circuit. A drive output terminal of the constant current drive circuit with the two LEDs. The single-chip microprocessor is in a sleep mode during a treatment process, so that the power consumption of the whole phototherapy instrument is reduced substantially. The constant current drive circuit maintains constant current output, so that the output optical power of the two LEDs is maintained at a constant state and the treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a phototherapy instrument for rhinitis. Background technique [0002] Allergic rhinitis refers to the inflammation of the nasal mucosa and submucosal tissue caused by the body's allergy to certain substances, manifested as congestion or edema, which can cause nasal congestion, runny nose, sneezing, nasal itching and other symptoms. The main pathogenesis is that inhaled allergens, such as pollen particles, dust and other allergens, cause the body to produce type 1 allergy. Traditional treatment methods for allergic rhinitis include drug therapy, surgical therapy, and desensitization therapy. However, drug therapy: antihistamines have different degrees of central nervous system inhibition and cause dizziness, drowsiness and other symptoms. Commonly used drugs can have adverse effects on the liver, especially in children, and long-term use is prone to drug resistance. And ...
