Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a fixed teeth pad for endotracheal intubation. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal tube through the mouth or nasal cavity and into the trachea or bronchus via the glottis, providing optimal conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure to rescue patients with respiratory dysfunction.

[0003] However, existing endotracheal tube holders have some shortcomings. For example, existing endotracheal tubes require a bite block to protect them from deformation caused by the patient's teeth. The bite block is fixed to the patient's head via a holder. The existing bite block and holder are integrated into one structure, requiring replacement if contaminated, resulting in high costs for the patient. Furthermore, the bite block cannot be moved relative to the holder, making regular decompression inconvenient. Furthermore, existing bite blocks can only be used to secure the endotracheal tube; a suction tube is also required during actual treatment, and there is no mechanism to secure the tube.

[0004] To this end, the utility model provides a tracheal intubation fixing teeth pad. Utility Model Content

[0015] 3.Beneficial effects:

[0016] The dental pad of this utility model can simultaneously fix the endotracheal tube and the sputum suction tube, and can simultaneously suck oral secretions while providing ventilation and oxygen, thus preventing invisible aspiration. In addition, the dental pad is movably and detachably mounted on the retainer, and can be fixed at any point on the front frame, so that the retaining sleeve bitten by the teeth can be translated and repositioned, and decompression can be performed regularly. The detachable design allows the dental pad to be separated from the retainer when contaminated and replaced separately, thus reducing the patient's medical expenses. At the same time, by improving the contact position between the retaining sleeve and the teeth to a flexible decompression dressing, pressure injuries to the oral mucosa can be prevented.

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] As attached Figure 1 To the attached Figure 4 ,

[0023] Example 1:

[0024] like Figure 1-3 The tracheal tube 3 is fixed with the first clamping plate 5 and the first clamping plate 6 on the fixing sleeve 2. The first clamping plate 5 is hinged on the first clamping plate 4 and the first clamping plate 6 is engaged with the first clamping block 6 on the fixing sleeve 2. The first clamping plate 5 and the first clamping block 6 cooperate to engage with each other, thereby fixing the tracheal tube 3 in the first limiting groove; the other side of the fixing sleeve 2 relative to the opening is provided with a second limiting groove, and the second limiting groove can accommodate a sputum suction tube 7. The outer side of the second limiting groove is provided with a hinged second pressing plate 8, and the end of the second pressing plate 8 is provided with a second clamping groove 9, which is engaged with the second clamping block 10 on the fixing sleeve 2. The second clamping groove 9 and the second clamping block 10 cooperate to engage, thereby fixing the sputum suction tube 7 in the second limiting groove. The first pressing plate 4 and the second pressing plate 8 are respectively located on both sides of the fixed sleeve 2. When in use, the fixed sleeve 2 is inserted into the patient's mouth, and the patient's teeth bite the top and bottom of the fixed sleeve 2. Flexible decompression dressings are provided on the top and bottom of the fixed sleeve 2. This embodiment improves the structure of the tooth pad, and an endotracheal tube 3 and a sputum suction tube 7 can be installed at the same time. Oral secretions can be sucked while ventilation and oxygen supply are being performed to prevent invisible aspiration. The sputum suction tube 7 can be used to attract subglottic secretions. In addition, the position where the fixed sleeve contacts the teeth is improved to be a flexible decompression dressing, which can prevent pressure damage to the oral mucosa.

[0025] Example 2:

[0026] like Figure 1-2 The fixer 1 includes a front frame 11 made of flexible plastic material. Both ends of the front frame 11 are provided with connecting holes, and a fixing belt 12 is connected in the connecting hole.

[0027] The connecting member 13 includes an arc-shaped support plate 15 arranged on the inner side of the front frame 11, a flexible pad 16 is provided behind the support plate 15, an L-shaped connecting plate 17 is fixed to the front end of the support plate 15, a through groove is formed between the L-shaped connecting plate 17 and the support plate 15, the front frame 11 is movably fixed in the through groove, the connecting plate 17 is fixedly connected to the fixing sleeve 2, and an extension plate 21 is provided at the top front end of the fixing sleeve 2, the extension plate 21 is fixedly connected to the support plate 22, and the support plate 22 is fixedly connected to the connecting plate 17.

[0028] During use, the flexible pad 16 rests between the patient's mouth and nose, the fixed sleeve 2 is inserted into the patient's mouth and held by the patient's upper and lower teeth, the face patch 14 is attached to the sides of the patient's face, and the fixed strap 12 wraps around the patient's head to secure the device. Because the front frame 11 is movably fixed in the slot, the fixed sleeve 2 can be moved around the patient's mouth to change position and provide regular decompression.

[0029] Example 3:

[0030] like Figure 2 The front end of the connecting plate 17 is provided with a threaded hole, and a fixing bolt 18 is threadedly connected to the threaded hole. The fixing bolt 18 squeezes the front frame 11 and fixes it. The connecting plate 17 can be fixed to any position of the front frame 11 by the fixing bolt 18. When disassembling or adjusting the position, just loosen the fixing bolt 18.

[0031] Example 4:

[0032] like Figure 4 Two clamping pieces 19 are symmetrically hinged on either side of the front end of the connecting plate 17. The hinges of the clamping pieces 19 are equipped with torsion springs. The front end of the front frame 11 is provided with a series of evenly spaced protruding teeth 20. The two clamping pieces 19 clamp onto the outermost edges of a plurality of adjacent protruding teeth 20. The protruding teeth 20 are clamped and secured by the two clamping pieces 19. Grooves are also provided on either side of the protruding teeth 20 for easy clamping. The ends of the clamping pieces 19 are clamped into the grooves and prevent them from falling out.
