Problems solved by technology

[0007] (1) If the pressure is small, air leakage is prone to occur; but if the pressure is too high and the compression time is too long, the airway mucosa will have serious consequences of ischemic necrosis
At present, most of the clinical use relies on the doctor's clinical experience to evaluate the pressure of the airbag, and the accuracy is poor; even if professional pressure detection equipment is used for detection, it is difficult to determine the optimal value and change law of the pressure, and the process is cumbersome. The airway pressure often changes constantly, and the pressure in the cuff is difficult to be accurately grasped
[0008] (2) There is an opening on the dorsal side above the air bag of the tracheotomy sleeve, which communicates with the outside through a pipeline along the tube wall. The secretion on the dorsal side of the tube is called "subglottic suction". This subglottic suction method has the problem that if the negative pressure is small, it cannot be sucked, and if the negative pressure is large, the tracheal mucosa will be sucked to the opening, causing airway mucosal damage.

Embodiment 1

[0058] Embodiment one: figure 1 As shown, a double-layer balloon tracheotomy sleeve includes a cannula 1, and the insertion end of the cannula 1 is provided with two double-layer airbags 2 at intervals. The airbag 20 and the fixed airbag 21 outside the tube 1.

[0059] The safety airbag 20 and the intubation tube 1 are surrounded to form a safety air chamber, which communicates with the inner hole of the intubation tube 1 .

[0060] The fixed airbag 21 is surrounded by the intubation tube 1 and the safety airbag 20 to form a fixed air chamber, which is connected with the gas injection tube 3 .

[0061] Adjacent to the upper edge of the fixed balloon 21 , a set of suction holes is provided on the tube wall of the intubation tube 1 , consisting of 3 to 5 suction holes 10 on the back side of the cannula 1 . Wherein, 3 to 5 of the suction holes 10 are located on the same cross section, taking the dorsal line of the cannula as the center line, and radially distributed within 30° ...

Embodiment 2

[0091] Embodiment 2: Embodiment 2 of the present invention prepares such as by following method figure 1 For the double-layer balloon tracheostomy tube shown, the steps are as follows:

[0092] (1) 3000g medical-grade polyethylene, 60g zinc-based antibacterial agent, 90g aminoglycoside, 1200g diisononyl phthalate, 150g barium stearate, 90g rare earth stabilizer and 600g chlorinated polyethylene fat are mixed in proportion Mix evenly in a high-speed mixer to make composite materials;

Abstract

The invention discloses a tracheotomy sleeve with double-layer air bags and a preparation and use method thereof. The tracheotomy sleeve comprises an inserting tube, wherein the inserted end of the inserting tube is provided with 1-2 double-layer air bags at interval; each double-layer air bag comprises a safety air bag and a fixed air bag which are sheathed outside the inserting tube in sequence; a safety air chamber is enclosed by each safety air bag and the corresponding inserting tube and is communicated with an inner hole of the inserting tube; each fixed air chamber is enclosed by each fixed air bag, the inserting tube and the corresponding safety air bag and is connected with an air injecting tube. The tracheotomy sleeve disclosed by the invention has the advantages that the inserted end of the inserting tube is provided with the double-layer air bags, so that the opportunity that the same part is pressed for a long time to influence local blood circulation and cause necrosis of the airway mucosa is reduced; simultaneously, due to the double-layer air bags, the whole airway can be in a sealed state all the time, and normal mechanical ventilation is maintained.

Description

technical field [0001] The invention relates to a clinical medical device, in particular to a double-layer air bag tracheotomy sleeve and a preparation and use method thereof. Background technique [0002] Mechanical ventilation is an important life-saving technology in modern medical technology. The ventilator is connected to the patient through tracheal intubation or tracheostomy tube, especially for patients who need to use the ventilator for a long time, because the time for tracheal intubation is generally It should not exceed one week. Clinically, a tracheostomy tube is usually used instead of the tracheal intubation to reduce the patient's discomfort and reduce the chance of laryngeal edema during tracheal intubation and extubation. [0003] At present, the tracheostomy sleeve has the following problems in use: [0004] Adverse effects on patients when the inflatable air bag is inflated and deflated: In order to prevent air leakage from the gap between the tracheosto...
