Single-cavity double-sac tracheal catheter
Technical Field
The utility model belongs to the technical field of medical instrument.
Background
Endotracheal intubation refers to a technique in which a special endotracheal tube is placed into the trachea through the glottis and assisted breathing is provided by a ventilator. The technology can provide optimal conditions for airway smoothness, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like. In order to meet the requirements for ventilation and isolation of the lung lobes, a physician typically performs an endotracheal intubation on a patient during a pulmonary or esophageal procedure on the patient to ensure patient safety and to establish appropriate conditions for successful operation.
In one lung operation, when a doctor operates on the lung lobe or the esophagus on one side of a patient, the healthy lung lobe of the patient needs to be kept to be independently ventilated; or when the esophagus operation is carried out, one healthy lung lobe is required to be collapsed, so that the operation visual field is convenient to expose. During surgery on the lobes of the lungs or esophagus by a physician, it is necessary to keep the healthy lobes ventilated while the operative side lobes are ventilated. In the course of a surgery, need to satisfy and ventilate for one side healthy lobe alone, still need to satisfy and ventilate simultaneously two lobes, the condition of ventilating needs to carry out many times to switch when necessary.
In the single-cavity tracheal intubation in the prior art, when the tracheal intubation is performed, the diameter of the single-cavity tracheal intubation is small, the intubation can be performed by means of a visible laryngoscope, the intubation operation is very simple and convenient, and the error is not easy to occur. However, when ventilation is needed to the lung lobes on the other side in the operation process, the patient needs to be intubated again, so that the injury to the patient is very large, and the trachea of the lung is easily damaged.

Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the sputum aspirating device comprises a catheter 1, a connector 2, an air outlet 3, a first air bag 4, a second air bag 5, a first inflation valve 6, a second inflation valve 7, a first inflation tube 8, a second inflation tube 9, an air tube 10, a bronchus 11, a sputum aspirating port 12 and a sputum guiding channel 13.
Example one
Substantially as shown in figure 1: the single-cavity double-sac trachea 10 catheter 1 comprises a catheter 1 with an arc-shaped structure, and the catheter 1 is made of polyvinyl chloride; the upper end of the conduit 1 is coaxially and fixedly communicated with a connector 2, the connector 2 can be connected with a breathing machine in the prior art, and the lower end of the conduit 1 is provided with an air outlet 3. The outer contour of the lower end of the guide pipe 1 is a wedge-shaped structure.
The catheter 1 is provided with a first air bag 4 for blocking the trachea 10 and a second air bag 5 for blocking the bronchus 11 in sequence from top to bottom. The first air bag 4 and the second air bag 5 are mutually attached to the outer wall of the catheter 1, the first air bag 4 and the second air bag 5 are annular, and the side walls of the annular inner rings of the first air bag 4 and the second air bag 5 are fixedly adhered to the outer wall of the catheter 1.
The first air bag 4 is communicated with a first inflation tube 8, and the second air bag 5 is communicated with a second inflation tube 9. And the left end of the first inflation tube 8 is fixedly communicated with a first inflation valve 6, and the left end of the second inflation tube 9 is fixedly communicated with a second inflation valve 7.
The specific implementation process is as follows: before lung surgery is performed on a patient, a common trachea 10 intubation method can be used for performing trachea 10 intubation on the patient. In performing intubation of the trachea 10, the bottom end of the catheter 1 in this embodiment is first inserted into the bronchus 11 of the right healthy lung side, and the second balloon 5 is also positioned inside the bronchus 11 of the right healthy lung.
Then the operator inflates the first air bag 4 through the first inflation valve 6, and the air passes through the first inflation tube 8 through the first inflation valve 6, and finally reaches the effect of inflating the first air bag 4 in the first air bag 4. The first balloon 4 is inflated until the outer wall of the first balloon 4 is tightly attached to the inner wall of the trachea 10, and finally the purpose of fixing the position of the catheter 1 by the first balloon 4 is achieved. As shown in fig. 1, in this state, the second air cell 5 is in a contracted state, and after the gas is exhausted from the end of the bottom of the catheter 1, a part of the gas enters the right lung through the right bronchus 11, and the rest of the gas enters the left bronchus 11 along the gap between the right bronchus 11 and the catheter 1, and enters the left lung through the left bronchus 11, thereby achieving the technical effect of double lung ventilation.
When it is desired to perform an oxygen supply only to the right healthy lung, as shown in fig. 2, it is only necessary to inflate the first balloon 4 and also the second balloon 5. The principle of inflation of the second bladder 5 is the same as that of inflation of the first bladder 4. The second balloon 5 is inflated to expand the outer wall of the second balloon 5 to abut against the inner wall of the right bronchus 11. In this state, due to the blockage of the second air bag 5 after inflation, the gas discharged from the air duct 10 can only enter the right healthy lung, and finally the technical effect of single lung ventilation is realized. The ventilation operation of the bilateral lungs and the ventilation operation of the unilateral lungs are switched, and the condition that the trachea 10 of the lungs is damaged due to repeated movement of the catheter 1 is avoided.
Example two
The difference between the embodiment and the first embodiment is that as shown in fig. 3 and fig. 4, a sputum suction port 12 is formed on the outer wall of the catheter 1, the sputum suction port 12 is located between the first air bag 4 and the second air bag 5, a sputum guide channel 13 communicated with the sputum suction port 12 is formed on the side wall of the catheter 1, and one end of the sputum guide channel 13 far away from the sputum suction port 12 is communicated with the outside of the catheter 1.
The specific implementation process is as follows: when the patient has the phlegm accumulation in the trachea 10, the medical staff only needs to butt the instrument for absorbing the phlegm at the top of the phlegm guide channel 13, the instrument sucks the accumulated phlegm accumulated in the trachea 10 through the phlegm absorbing port 12, and finally the technical effect of eliminating the phlegm is achieved.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be pointed out that to those skilled in the art, without departing from the structure of the present invention, a plurality of modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the utility of the present invention.
