Description
Technical Field
The application relates to the field of medical equipment, in particular to an airway intubation device for drowners for intensive care and a use method thereof.
Background
When the patient suddenly suffers from respiratory arrest, cardiac arrest, respiratory tract obstruction and the like, a respiratory channel is established for the patient, and ventilation and oxygen supply are carried out on the patient, so that oxygen required by the body of the patient is maintained, and the life and the health of the patient can be effectively saved in time; meanwhile, when general anesthesia operation is performed, because the patient cannot breathe spontaneously, ventilation and oxygen supply can be performed on the patient in a trachea cannula mode, so that oxygen in the patient is ensured to be supplied in the operation process; and secondly, the tracheal cannula can timely suck out secretion or foreign matters in the respiratory tract, prevent the foreign matters from entering the respiratory tract, keep the respiratory tract unobstructed, perform effective artificial or mechanical ventilation and prevent hypoxia or carbon dioxide retention of a patient.
The tracheal intubation technology realizes the effect of ventilation and oxygen supply to the lung of a patient by a mode of putting a special catheter into the trachea of the patient through the oral cavity or the nasal cavity of the patient and then through the glottis of the patient, wherein the mode of entering through the oral cavity is simpler and faster to operate and wider to use than the mode of entering through the nasal cavity. When ventilation and oxygen supply are performed, in order to timely perform sufficient oxygen supply on a patient, an intubation tube matched with the diameter of the trachea of the patient is adopted to perform oxygen supply, meanwhile, the existing trachea intubation tube is hard in material, the trachea of a human body is always positioned in the human body, and the inner wall of the trachea is very tender and fragile, so that excessive friction occurs between the outer wall of the intubation tube and the inner wall of the trachea when the trachea intubation is performed, and the patient can feel that foreign matter friction pain is hard to endure; the patient cannot bear the trachea cannula when the patient wakes up, so that most of trachea cannulas are operated after anesthesia, but even if the trachea cannula is operated during anesthesia, the cardiovascular system and the human physiology of the patient can be obviously changed, and in the anesthesia recovery period, the patient can feel foreign bodies, choking cough is generated, and the wound can be torn when serious; the foreign body sensation can also lead the patient to involuntarily want to pull out the inserted cannula, so that the patient needs to be bound, and the patient is inconvenient to move.
When the trachea cannula is operated, whether the insertion position of the trachea cannula is proper or not needs to be ensured, if the trachea cannula is inserted too deeply, the trachea cannula enters a bronchus of one side lung, and the lung can be caused to be not stretched, so that one side lung lobe is caused to be not breathed, and ventilation of the lung lobe is influenced; if the intubation tube is inserted too shallow, the intubation tube is easy to deviate from and leak air, so that the lower end of the intubation tube is placed at a position which is more than two centimeters away from the junction of the trachea and the left bronchus and right bronchus to ensure that the intubation tube can smoothly ventilate. However, because the body condition of each person is different, the insertion depth of the insertion tube is also different, in order to smoothly ventilate and supply oxygen to different persons, scale marks are arranged on the insertion tube, the depth range of the insertion tube is summarized according to the length of the trachea of most persons, and meanwhile, after the insertion is finished, a stethoscope is used for listening to ventilation sounds of two lungs of a patient to determine whether the insertion tube is proper or not. When the operation mode is used for emergency treatment, medical staff is required to have a great deal of intubation experience to ensure that the patient can be timely supplied with oxygen just by being inserted properly at one time, and if the insertion position is improper, the catheter is required to be adjusted, so that the rescuing time of the patient is delayed, and the life and the health of the patient are endangered.
Based on the problems, the design of the airway intubation device for the drowner for intensive care and the use method thereof are needed, when the trachea intubation is carried out, the intubation can be conveniently carried out, the airway intubation device can be matched with the inner diameter of the trachea of a patient after the intubation is carried out, and the patient can be fully ventilated and supplied with oxygen; meanwhile, the foreign body sensation of a patient can be reduced after the intubation tube enters the intubation tube, so that the uncomfortable response of the patient is reduced, and the patient can be treated stably; meanwhile, the intubation tube can be directly inserted into a proper position after entering, the intubation tube does not need to be adjusted for multiple times, the emergency patient is timely ventilated and supplied with oxygen, and the life safety of the patient is guaranteed.

Detailed Description
The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. Further, it will be understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the application, and equivalents thereof fall within the scope of the application as defined by the claims.
When rescuing a patient suffering from respiratory disturbance and incapable of spontaneous breathing, the patient is ventilated and supplied with oxygen by adopting an endotracheal intubation mode, so that the life safety of the patient is ensured, but when the tracheal intubation is performed, the patient can obtain sufficient oxygen, the catheter 1 matched with the patient is adopted for use, when the adult patient is intubated, the catheter 1 with the inner diameter of 7mm, 7.5mm and 8mm and the outer diameter of 9.5mm, 10.2mm and 10.9mm is adopted, but when the adult patient is intubated, the adopted catheter 1 is required to be calculated according to the width of the small finger tips of the child and the height of the child. This results in the need to calculate in advance the catheter 1 required by the patient when rescuing; simultaneously when carrying out the intubate, because pipe 1 external diameter and patient's internal diameter trachea looks adaptation, will lead to pipe 1 to appear rubbing with patient's trachea to pipe 1 material is harder, and patient's trachea inner wall is in human inside all the time simultaneously, therefore makes the trachea inner wall surface tender fragile, just leads to too much friction when carrying out the intubate and makes the patient can feel obvious foreign matter friction pain sense and cause the patient to be intolerable.
The application relates to an airway intubation device for drowners for intensive care, as shown in figure 1, a main structure comprises a catheter 1, the catheter 1 is placed in a patient's trachea for ventilation and oxygen supply, the device is specially arranged for the catheter 1, the catheter 1 is made of soft deformable materials, and the catheter 1 is made of rubber materials specifically, so as to cope with a self-expanding bracket 2 arranged in the middle catheter 1, because the outer layer of the catheter 1 can be always adhered to the self-expanding bracket 2 for movement when the self-expanding action force of the self-expanding bracket 2 is expanded or when the catheter 1 is compressed by a middle pressure holding structure, and meanwhile, friction injury to the patient's trachea can be reduced after the catheter 1 enters the patient's trachea by adopting the soft materials.
