Description

A disposable endotracheal tube with built-in dental pad

Technical Field

The utility model relates to the technical field of medical instruments, and more specifically to a disposable endotracheal tube built-in teeth pad.

Background Art

Tracheal intubation is a surgical procedure that inserts a special endotracheal tube into the trachea through the glottis. Tracheal intubation is also an important technology in the medical field and one of the most widely used, quickest and most effective means of airway management. Tracheal intubation is the most commonly used medical device in clinical emergency resuscitation, rescue of patients with respiratory arrest, surgical anesthesia and airway opening. The endotracheal tube is inserted into the patient's trachea through the mouth or nose. The safe fixation of the endotracheal tube during use is an important guarantee for the success of the operation.

The existing disposable dental pads have poor integration with the endotracheal tube, and can be easily pushed out of the patient's teeth, flattening the endotracheal tube and failing to fix it. At the same time, the fixation method between the endotracheal tube and the disposable dental pad is complicated and easily displaced, causing the endotracheal tube to fall out.

Utility Model Content

The technical problem to be solved by the utility model is to provide a disposable endotracheal tube built-in teeth pad in view of the above-mentioned defects of the prior art.

The technical solution adopted by the utility model to solve its technical problems is:

A disposable endotracheal tube built-in bite block is constructed, comprising a bite block outer tube and a fixed inner tube fixedly arranged inside the bite block outer tube; the left end of the bite block outer tube protrudes more than the left end of the fixed inner tube, the right end of the bite block outer tube is provided with two oppositely arranged limiting wings, the limiting wings are provided with fixing holes, the right end of the fixed inner tube is connected with an extension handle for installing an endotracheal tube, an outer tube adjustment groove is axially provided on the tube wall of the bite block outer tube, an inner tube adjustment groove is axially provided on the tube wall of the fixed inner tube, and the inner tube adjustment groove is arranged directly opposite to the outer tube adjustment groove.

Preferably, the width of the outer tube adjustment groove is 20% of the outer circumference of the outer tube of the bite block.

Preferably, the width of the inner tube adjustment groove is 20% of the outer circumference of the fixed inner tube.

Preferably, the cross section of the extension handle is in the shape of a quarter of a circle.

Preferably, the extension handle and the fixed inner tube are an integrally formed structure.

Preferably, it further comprises an endotracheal tube, wherein the endotracheal tube is connected to the extension handle via adhesive tape.

The beneficial effects of the utility model are:

The utility model discloses a disposable endotracheal tube with a built-in dental pad. The outer tube of the dental pad and the fixed inner tube are both designed in an open form (80% circular ring) and can be directly clamped on the outside of the endotracheal tube, occupying a small area of the oral cavity and facilitating oral care. At the same time, the fixed inner tube is provided with an extension handle fixedly connected with the endotracheal tube to prevent the endotracheal tube from moving inside and outside and causing the tube to fall out. The outer tube of the dental pad is provided with a soft rubber limiting wing with a hole, which can be used to connect the fixing belt. By providing the built-in dental pad, the patient's comfort can be improved, and the endotracheal tube can be protected from being bitten by the front teeth.
