Nasal catheter fixation device for use with neonatal cpap ventilator

Abstract

The invention discloses a nasal congestion catheter fixing device used in conjunction with a neonatal CPAP ventilator. Oxygen mixing valve seat, the invention realizes the use of nasal plug intubation plate and liquid oxygen mixing valve seat to cooperate, and the gas circuit of pure oxygen gas storage tank and humidification tank liquid are connected by using the curved recoil pipe of the liquid oxygen mixing valve seat to connect the cover cap Road treatment to ensure that the water vapor stays in the airway tube and the nasal plug board to the minimum pressure, and at the same time, the recoil force rotates to filter the condensed liquid state of the tidal volume, ensuring that the water vapor is sufficiently mixed with oxygen to achieve the moisturizing effect of oxygen supply, so that the expansion of the alveoli is affected Water vapor adhesion can be alleviated, the continuous drying of the lung can be adjusted, the respiratory muscles can be relaxed, lubricated and elastic, the functional residual capacity can be increased, the lung compliance can be improved, and the breathing regularity of newborns can be improved, so that the equipment can independently cooperate with the physical needs of children to achieve micro-adjustment of mixing. The effect of strong oxygen adaptability.

Description

technical field [0001] The invention relates to a nasal congestion catheter fixing device used in conjunction with a neonatal CPAP ventilator, and belongs to the field of medical equipment. Background technique [0002] CPAP is continuous positive airway pressure, which uses a mask to send continuous positive airflow into the airway. The machine that uses this method to supply oxygen is called CPAP ventilator. The respiratory care of newborns is equipped with a nasal catheter for non-invasive breathing, which is convenient for the airway in the equipment to directly supply oxygen and breathe anti-infection, and avoid contact with the external dust environment. The current technology is common The disadvantages to be optimized are: [0003] It is a non-invasive ventilator that sends a continuous positive pressure air-oxygen mixture into the patient's airway through nasal congestion. This type of equipment prevents infection and facilitates timely disassembly and ventilation ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a nasal catheter fixing device used in conjunction with the neonatal CPAP ventilator, so as to solve the problem of sending continuous positive pressure air-oxygen mixture into the patient's airway through nasal congestion. This type of equipment prevents infection for the oxygen supply breathing operation of newborns and facilitates timely disassembly and ventilation to the outside world. However, the non-invasive oxygen supply for premature infants requires a mixed tidal volume, which increases the water vapor in the airway of the mask and the hydraulic pressure. When the air pressure is increased, the air pressure is retracted and lowered, causing lung respiratory collapse, resulting in a large range of alveolar respiratory contraction in newborns, resulting in sudden respiratory arrest and irregular heart rate oxygen supply, which greatly threatens the fragile body functions of newborns. Minor deviations in volume and tidal volume can have serious late effects and pose potential chronic dyspnea problems for neonatal medical care
