TECHNICAL FIELD
[0001] The utility model belongs to the art of artificial airway equipment field, concretely relates to a tracheal tube with tooth pad. BACKGROUND
[0002] Tracheal tube is a first-aid technique, which is used for establishing artificial airway, and is usually inserted into trachea through oral cavity or nasal cavity. This technique is very important for patients who need mechanical ventilation, respiratory tract suction, prevention of aspiration or maintenance of respiratory tract patency.
[0003] Human airway has more mucus, so the inner wall of human airway is relatively slippery. After the tracheal tube is inserted, the tracheal tube will slowly slide out of the human body due to poor compliance of the patient, which leads to poor ventilation effect of the tracheal tube. In order to prevent the tracheal tube from sliding outwards, the tracheal tube on the market currently is provided with a tooth pad at the middle segment of the tracheal tube, which is convenient for the patient to press and prevent the tracheal tube from sliding out. However, such tooth pad is usually in a cylindrical shape, or only a limiting protrusion is arranged on the tooth pad, and such design has great defects. When the patient does not bite the tooth pad or slides out from the limiting protrusion, it is easy to cause large displacement of the tracheal tube. In order to solve the above problems, the utility model hopes to provide a tracheal tube with tooth pad. SUMMARY
[0004] The utility model aims at providing a tracheal tube with tooth pad to solve the problems in the above background.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0006] A tracheal tube with tooth pad, comprising a main tube, a tooth pad is arranged on the outer wall of the main tube, the cross section of the tooth pad is in an oval shape, a plurality of fixed teeth one is arranged on the front surface of the tooth pad, and a plurality of fixed teeth two is arranged on the back surface of the tooth pad.
[0007] Preferably, a spring piece is arranged in the tube wall of the main tube, the spring piece is embedded in the tube wall of the main tube, and the axis of the spring piece coincides with the axis of the main tube.
[0008] Preferably, the tooth pad is located in the middle and upper half segment of the main tube.
[0009] Preferably, an inflatable bag is arranged on the outer wall of the main tube, an inflatable side branch is arranged on the main tube, the inflatable side branch is connected with the inflatable bag, and the inflatable bag is located in the lower half segment of the main tube.
[0010] Preferably, a connecting tube port is arranged on the head of the main tube.
[0011] Preferably, a wedge-shaped tube port is arranged on the tail of the main tube, and the wedge-shaped tube port is curved in the shape of an eagle's beak.
[0012] Preferably, the inner part of the dental pad is provided with a mounting hole, and the main tube is fixed through the mounting hole.
[0013] Compared with the prior art, the utility model has the beneficial effects that:
[0014] (1) the tracheal tube with dental pad has a plurality of fixed teeth one on the front surface of the dental pad and a plurality of fixed teeth two on the back surface of the dental pad, and is designed as multi-stage fixed teeth one and fixed teeth; when a patient does not bite the previous pair of fixed teeth one and fixed teeth two, the patient can still bite the next pair of fixed teeth one and fixed teeth two, and the tracheal tube cannot be withdrawn from the human body by a large length;
[0015] (2) the tracheal tube with dental pad has an oval cross section of the dental pad, which can avoid the tracheal tube from being twisted in the human body, and the tracheal tube twisting can cause the lumen to be smaller;
[0016] (3) the tracheal tube with dental pad has an inflation bag on the outer wall of the main tube, which is fixed in the airway after inflation and expansion, and can prevent the tracheal tube from sliding out. BRIEF DESCRIPTION OF DRAWINGS

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] A tracheal tube with a bite block, comprising a main tube 1. In the wall of the main tube 1, a spring member 2 is embedded, the axis of the spring member 2 coincides with the axis of the main tube 1, and the spring member 2 can prevent the lumen of the main tube 1 from being crushed. The head of the main tube 1 is provided with a connecting tube port 3, which can be used to connect external instruments. The tail of the main tube 1 is provided with a wedge-shaped tube port 4, which is designed to greatly increase the smoothness of the introduction into the main tube 1. At the same time, in order to prevent the wedge-shaped tube port 4 from injuring the inner wall of the airway, the wedge-shaped tube port 4 is curved like a beak.
[0023] In order to fix the tracheal tube inserted into the airway, an inflatable bag 5 is arranged on the outer wall of the main tube 1, and the inflatable bag 5 is located in the lower half of the main tube 1. At the same time, an inflatable side branch 6 is arranged on the main tube 1, the inflatable side branch 6 is connected to the inflatable bag 5, and the inflatable side branch 6 inflates the inflatable bag 5. When the tracheal tube is placed in the target position, the inflatable bag 5 is inflated, so that the inflatable bag 5 is filled and swollen, and is fixed in the airway.
[0024] In order to prevent the tracheal tube from sliding out, a bite block 7 is arranged on the outer wall of the main tube 2, the inside of the bite block 7 is provided with a mounting hole 8, and the main tube 1 is fixed through the mounting hole 8. The cross section of the bite block 7 is oval, and the whole bite block 7 is flat, and the bite block 7 in this shape can effectively avoid the twisting of the main tube 1 in the human body. If the twisting occurs, the lumen of the main tube 1 will be greatly reduced, which is not conducive to the ventilation of the patient. A plurality of fixed teeth one 9 are arranged on the front surface of the bite block 7, and a plurality of fixed teeth two 10 are arranged on the back surface of the bite block 7. A plurality of groups of fixed teeth one 9 and fixed teeth two 10 can effectively deal with the sliding of the bite block 7. When the teeth of the patient slide out of the fixed teeth one 9 and the fixed teeth two 10, they can slide to the adjacent group of fixed teeth one 9 and fixed teeth two 10, effectively preventing the main tube 1 from sliding out a long distance.
[0025] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
