Description

Connecting device for breathing machine and user

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a connecting device that is used for between breathing machine and the user.

Background

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a sleep respiratory disorder of unknown etiology with the clinical manifestations of nocturnal snoring with apnea and daytime sleepiness. Repeated nighttime hypoxia and hypercapnia caused by apnea can cause hypertension, coronary heart disease, diabetes, cerebrovascular disease and other complications and traffic accidents, and even sudden death at night. The direct pathogenesis is stenosis and obstruction of the upper airway, but its pathogenesis is not simple airway obstruction, actually upper airway collapse, and accompanying respiratory central nervous system regulator disorder. The home ventilator therapy is the only effective method for treating the sleep apnea syndrome in the world, and the method can achieve more than 95 percent of the sleep apnea syndrome without side effects. The principle is that the upper respiratory tract of a patient is opened by continuous positive air pressure, so that the blocked airway is kept smooth, the occurrence of blockage can be prevented, and good sleep quality is ensured. The household respirator consists of a small air compressor, a sensor, a power supply, a control circuit, a pipeline and a mask. The system identifies the characteristic points of the respiratory cycle by collecting and processing flow and pressure parameters to regulate and output airflow with certain level of positive pressure and flow.

As shown in fig. 1, the ventilator is generally placed on a bedside table, and one end of the pipeline (including the ordinary pipeline and the pipeline with functions such as heating) is connected to the air outlet of the ventilator, and the other end is connected to the ventilation mask. The length of the air path is generally 1.5m to 2m, and in the actual use process, the following inconveniences exist:

(1) when sleeping, a long pipe is connected to the breathing machine from the mouth and nose parts, the visual effect of the family is poor, the family feels uncomfortable, and a user is easy to touch the pipeline during sleeping, so that the situations of air leakage of the mask and the like are easy to occur, and the sleeping quality is also influenced. And when the respirator needs to be operated when the mask is worn for sleep, the operation is inconvenient. When a user needs to wear the blood oxygen probe for monitoring, the length of a cable of the probe is about 2 meters generally, and the cable and the air pipe are connected to the user from the host, so that more discomfort is increased.

(2) The sensor for detecting the pressure and the flow of the air path is positioned in the host, and because the pipeline is long, when the pressure and the flow of the inhaled or exhaled air of a user are changed, the sensor lags behind by about 5.3ms (the propagation speed of the wave in the air is calculated according to 340m/s, and for the air path with the length of 1.8m, the propagation time needs 5.3 ms) to sense.

(3) The pressure and flow sensors of the breathing machine are high in price, and account for high cost ratio of the whole machine.

(4) It is inconvenient to access other physiological parameter information and the breathing condition of the user cannot be known more comprehensively. And the oxygen access port is not available, and the oxygen therapy cannot be carried out when the oxygen therapy is needed.

(5) The air heating function is not available, the air temperature in the pipeline cannot be adjusted, and when the weather is cold, the breathing of cold air is harmful to the body, especially for the old.
