YH-QX-236 intermediate frequency therapeutic instrument

Intermediate-frequency therapeutic apparatus is a kind of physical therapy equipment that stimulates human tissues through intermediate-frequency current (1-10kHz). Its main functions include relieving pain, promoting local blood circulation, relaxing muscle spasm, accelerating tissue repair, etc. It is suitable for adjuvant treatment of chronic diseases such as muscle strain, arthritis and neuralgia.

YH-A9 polysomnography system

Polysomnography system is a medical device used in sleep medicine to diagnose sleep disorders. It is regarded as the "gold standard" to diagnose sleep apnea syndrome and other diseases by synchronously recording more than ten physiological parameters, such as EEG, EMG, ECG, oral and nasal airflow and oxygen saturation. The system consists of a host, a sensor and a collection box. It can set special leads to monitor periodic leg movement, abnormal REM sleep behavior and other diseases. It is clinically suitable for sleep evaluation of patients with insomnia, drowsiness, nocturnal behavior disorder and chronic diseases such as hypertension/diabetes.

Home-use ventilator

A home-use ventilator is a Class II medical device, mainly used to assist or replace spontaneous breathing. Its core functions include improving ventilation, correcting hypoxemia, providing respiratory support, reducing respiratory work, and enhancing sleep quality. It is suitable for patients with sleep apnea syndrome, chronic obstructive pulmonary disease (COPD), and other conditions. It can be safely used at home, but operation should be under the guidance of a doctor to avoid potential side effects.  1. Core Functions and Effects  Improving ventilation function: Maintaining airway patency through positive pressure ventilation, increasing alveolar ventilation volume, and promoting gas exchange, which is suitable for patients with COPD and other conditions.Correcting hypoxemia: Regulating the concentration of inhaled oxygen and end-expiratory positive pressure to increase blood oxygen saturation and reduce nocturnal hypoxia.Providing respiratory support: Offering ventilation support to patients with weak respiratory muscles or acute attacks (such as asthma) to prevent respiratory failure.Reducing respiratory work: Lowering the load on respiratory muscles, avoiding diaphragm fatigue, which is particularly beneficial for elderly or chronically ill patients.Improving sleep quality: Preventing sleep apnea through continuous positive airway pressure (CPAP), reducing nocturnal awakenings, and improving sleep structure.  2. Applicable Scenarios and PrecautionsApplicable Population: Those requiring long-term ventilation support, such as patients with obstructive sleep apnea, COPD, and chronic respiratory failure. Side effects: May cause ventilator dependence or bacterial infection. Regular cleaning and disinfection are required, and breathing exercises should be done in conjunction.Usage advice: Professional sleep monitoring and pressure titration tests are mandatory. Do not adjust parameters by yourself.
