Description

But lung ventilation unit of automatically regulated flow

Technical Field

The utility model relates to a lung ventilation device especially relates to a but lung ventilation device of automatically regulated flow.

Background

The alveoli are gas exchange parts, and the total number of the adult alveoli is 3-4 hundred million, so that a sufficient area is provided for gas exchange. There are two types of alveolar epithelial cells, one responsible for gas dispersion; another type can form a liquid film on the surface of the alveoli to reduce the surface tension of the alveoli and keep the alveoli expanded without collapsing at the end of expiration.

Data show that the incidence of atelectasis in anaesthesia-induced patients is more than 90%. During and after anesthesia, because various analgesics and sedatives are used to inhibit the sputum excretion function of the respiratory tract, viscous secretion is not capable of being coughed out, and small bronchus can be blocked. If the two lungs are not fully inflated after the operation, the postoperative analgesia is incomplete, the patient cannot breathe with strength, the expansion of the lungs is limited, and the pulmonary alveoli are atelectasis.

When pulmonary atelectasis occurs in the alveoli, the pulmonary atelectasis method is needed to realize the atelectasis of the collapsed alveoli. Pulmonary remodeling is the process of applying intermittently a pressure or volume above the normal mean airway pressure and maintaining it for a period of time during mechanical ventilation to remodel the collapsed alveoli.

However, during lung refolding process, if the fluctuation of the hemodynamic parameter is too large, the lung refolding operation needs to be terminated, and the existing device with the lung refolding function (such as an anesthesia machine) usually needs to realize the lung refolding by manually adjusting the ventilation mode setting parameter of the respirator. But has the following disadvantages: the replacement of the human breath by compression of a special resuscitation balloon or inflation balloon, either by mechanical operation of the lung ventilator or by manual operation of the operating subject, must be in contact with the respiratory system of the patient, either by adhesion to the face or by a special mask of the tube (usually the trachea), the connection tube between the resuscitation balloon or inflation balloon and any device to which it is connected is universal, whereas the lung capacity varies according to age group, sex, weight, height, respiratory diseases, in particular with obvious differences between adult patients, children, newborns, it is necessary to provide connection tubes of various sizes, and it is also necessary for the operator to have a certain experience due to the manual ventilation. If the volume of air/oxygen/gas is insufflated in an amount greater than the person's lung volume and pressure applied, significant and potentially serious traumatic consequences to the patient's respiratory system can result. In addition, the setting parameters can not be changed in time in emergency, resulting in the situations of treatment delay and the like.
