Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to an adjustable tracheal cannula fixing device. Background Art

[0002] Endotracheal intubation is a common medical procedure, mainly used to ensure the patency of the patient's airway, especially in surgical anesthesia, intensive care, and emergency rescue. The fixation of the endotracheal tube has always been one of the clinical problems. An unstable intubation may cause tracheal damage, tube position movement or even fall off, and in severe cases may cause suffocation of the patient.

[0003] The traditional method of fixing the endotracheal tube mainly relies on tape or bandage. This method is easy to operate, but has many shortcomings. The adjustability of this fixation method is poor. Once the position of the tube needs to be adjusted, it often needs to be re-fixed, which brings inconvenience to clinical operations. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an adjustable endotracheal tube fixing device, which effectively solves the problem that the existing endotracheal tube fixing method has poor adjustability and often needs to be re-fixed once the tube position needs to be adjusted, causing inconvenience to clinical operations.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model comprises an arc-shaped silicone part, a dental cap fixed in the middle of the inner side of the silicone part, and fixing belts arranged at both ends of the silicone part, and also comprises a connecting block and an adjusting mechanism, wherein the outer side of the silicone part is provided with a connecting block, and the outer side of the connecting block is provided with an adjusting mechanism;

[0006] The adjusting mechanism comprises a transverse plate, an adjusting rod, a sleeve, a fixing bolt, a moving block, an elastic sleeve, a fixing screw, a buffer spring, a through hole and a threaded hole. The transverse plate is fixed to the outer side of the connecting block. Two parallel adjusting rods are fixed to the outer side of the transverse plate. Four sleeves are sleeved on the adjusting rod. Fixing bolts are screwed on the outer edge of the sleeve. A moving block is fixed on the outer side of the sleeve. An elastic sleeve is arranged in the middle of the outer side of the moving block. Several fixing screws are screwed on the elastic sleeve. The fixing screws are located on the inner side of the elastic sleeve and are sleeved with buffer springs.

[0007] Preferably, a through hole is formed in the sleeve at a position corresponding to the adjusting rod.

[0008] Preferably, the elastic jacket is made of plastic, and the inner surface is provided with anti-slip grooves.

[0009] Preferably, a threaded hole is provided on the sleeve at a position corresponding to the fixing bolt.

[0010] Preferably, the elastic sleeve is provided with an insertion hole at a position corresponding to the fixing screw.

[0011] Preferably, the number of the fixing screws is at least two.

[0012] Beneficial effect: When the utility model is used, the braces are placed on the patient's mouth, and then the silicone part is fixed on both sides of the patient's mouth by the fixing belt. After the fixation is completed, the nasal tracheal tube is passed through the elastic jacket. After passing through, the fixing screw is tightened so that the elastic jacket clamps the tracheal tube. The buffer spring is used for buffering. At this time, the fixation of the tracheal tube can be completed. When the position of the tracheal tube needs to be adjusted, the fixing bolt is loosened. After loosening, the moving block is pushed. The moving block drives the sleeve to move on the adjusting rod. The movement of the moving block drives the elastic jacket to move, and the purpose of adjusting the position of the tracheal tube can be achieved. It is convenient to adjust when observing or intubating the trachea, and has strong applicability. The utility model has a novel structure and an ingenious conception. It is convenient to fix the nasal tracheal tube, has a good fixing effect, and is convenient to adjust when observing or intubating the trachea, and has strong applicability.
