Abstract

The utility model relates to the technical field of a medical apparatus, namely a digital control double air sacs trachea sleeve tube. The utility model improves the existing single air sac trachea sleeve tube into a double air sacs trachea sleeve tube, after the air sac is aerated, the gap between the trachea sleeve tube and the inner wall of the trachea is closed, the air sac can be alternately used, the time that the air sac compresses the local trachea mucosa is shortened, thereby the complication such as ischemia, blister and necrotize of a trachea mucosa or tracheal stenosis which is caused by compressing the inner wall of the trachea for a long time can be prevented or reduced. The digital control air sac pressure monitoring instrument is utilized to control press and time, which can alternately charge and discharge air for the double air sac in a certain time, and maintain the pressure in the air sac in a stable value.

Description

A kind of numerically controlled double air bag tracheal tube

technical field

The utility model relates to the technical field of medical equipment, which is a numerically controlled double-airbag tracheal tube.

Background technique

Clinically, patients undergoing tracheotomy often need to be placed with a tracheal tube to keep the airway open. Existing tracheal tubes include two parts, an outer tube and a tube core. Wherein the outer casing is composed of a casing, an indicating balloon, an inflation tube, an inflation valve, a fixed wing, and an air bag. The fixed wing is located on the outer wall of the proximal end of the cannula, and the air bag is located on the outer wall of the far end of the cannula. One end of the inflatable tube passes through the connection between the fixed wing and the cannula, extends along the tube wall of the cannula and is connected with the air bag, and the other end of the inflatable tube In order to indicate the balloon and inflation valve, the tube core is placed in the outer sleeve, and the proximal end is two square sheets, which cover the proximal nozzle of the outer sleeve, and the distal end is conical, just protruding from the distal nozzle of the outer sleeve. The function is to prevent the secretions in the trachea from entering the outer tube when inserting the trachea, and on the other hand, the smooth conical surface can prevent damage to the inner wall of the trachea. When in use, insert the outer cannula together with the stylet through the opening of the trachea and fix it with the fixed wings, pull out the stylet, connect the inflation valve with the syringe to inflate the airbag through the inflation tube, and make the airbag close the gap between the outer wall of the outer tube and the inner wall of the trachea This will not only prevent air leakage during mechanical ventilation, but also prevent oropharyngeal secretions or the contents of the nasogastric tube from entering the lower respiratory tract.

However, the above-mentioned tracheal tube has the following disadvantages: 1. The outer tube only has one air bag, and the long-term compression of the air bag on the tracheal wall is prone to mucosal ischemia, erosion, necrosis or granuloma and then causes symptoms such as tracheal stenosis. In 1969, Cooper and Grillo confirmed that only 48 hours after the balloon inflation of the tracheal tube, the tracheal mucosa was ulcerated. In 1984, Wited confirmed that the occurrence of tracheal stenosis was related to the length of intubation time. Among patients who were intubated for more than 11 days, 12% developed gas The airway is narrow, and the usual time of use is 2 to 3 weeks, so the incidence of the above symptoms is relatively high; 2. The airbag is inflated by a syringe, and the amount of inflation is difficult to control. If the airbag is inflated too much, the pressure of the airbag is too high to compress the tracheal wall, which will easily cause mucosal defect. Blood, erosion, and necrosis; air leakage occurs during mechanical ventilation if the air bag pressure is too low. This is a problem that the existing tracheal tubes are difficult to solve.

Invention content:

The purpose of this utility model is to provide a kind of numerical control double-airbag tracheal tube, which changes the existing tracheal tube from a single airbag to a double-airbag, that is, the outer wall at the far end of the outer tube is provided with two airbags, which are respectively connected with the respective inflatable tubes. Connected to make alternate inflation and deflation, to prevent tracheal mucosal ischemia, erosion, necrosis and other symptoms due to long-term pressure on the inner wall of the trachea. The inflation pressure and the time for the two airbags to inflate and deflate alternately. Thereby, the technical problems existing in the existing tracheal tube can be overcome.

The utility model includes two parts, an outer casing 1 and a tube core 2. The outer casing 1 is composed of a casing 1.1, a fixed wing 1.2, an airbag 1.3, an inflatable tube 1.4, an inflatable valve 1.5 and an indicating balloon 1.6. It is characterized in that there are two airbags , two inflation tubes, two inflation valves and two indicator balloons. It can also include an airbag pressure monitor 3, and two inflation valves 1.5 are respectively connected with two inflation and deflation pipes 3.1 of the airbag pressure monitor 3. The balloon pressure monitor is similar to that of commercially available digitally controlled pneumatic tourniquets used in extremity surgery.

The utility model shortens the compression time of the local tracheal mucous membrane due to the alternate use of double airbags, thereby reducing complications. Due to the use of a numerically controlled airbag pressure monitor, it can not only inflate and deflate the double airbags alternately at regular intervals, but also automatically measure and maintain the pressure. , making the operation more scientific and convenient. Of course, if the numerical control airbag pressure monitor is not used, the double airbags can be inflated and deflated alternately by hand.
