Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a detachable anesthesia intubation cannula anti-bite dental pad. Background Technology

[0002] A endotracheal intubation bite block is attached to the teeth in the mouth along with the endotracheal tube. Endotracheal intubation is a method of inserting a tube into the trachea or bronchus to provide oxygen and keep the airway open. The purpose of the bite block is to prevent the patient from biting the tube. The tube is placed in the center of the mouth, and the bite block is placed between the upper and lower molars and secured to the tube with adhesive tape.

[0003] A search of Chinese patents revealed publication number CN209848069U, which describes a tracheal intubation mouthguard. However, this mouthguard lacks a fixing function. Typically, mouthguards require the patient to hold them in their mouth for fixation before intubation. During intubation, the tube irritates the patient's throat, causing discomfort and making it difficult to hold the mouthguard stably, leading to it falling off and affecting usability. It is inconvenient to use, as mouthguards are generally fixed in size and cannot be adjusted according to the size of the patient's mouth, reducing practicality and applicability. Furthermore, mouthguards cannot be replaced, as they are usually integrated with the fixing tube; if the mouthguard is damaged, the entire device must be discarded, increasing usage costs and further reducing practicality. To address these problems, we propose a detachable anesthesia intubation anti-biting mouthguard. Utility Model Content

Furthermore, the bidirectional toothed rod 8 is slidably connected to the inner wall of the fixing head 4, and the surface of the second fixing band 3 is embedded with a snap-fit ​​toothed rod 9, which is adapted to the snap-fit ​​plate 5. By placing the fixing tube 1 in the patient's mouth, the dental pad 15 supports the teeth. Then, the second fixing band 3 is inserted into the fixing head 4 and the required tightness is adjusted. Under the action of the spring, the transmission toothed rod 6 drives the snap-fit ​​plate 5 to snap-fit ​​with the snap-fit ​​toothed rod 9, thus fixing them. This method can achieve the purpose of fixing, improve stability, and facilitate use.

[0030] refer to Figure 1 and Figure 5 One end of the bidirectional rack 8 is bolted with a pressing block 20, which facilitates the movement of the bidirectional rack 8.

[0031] refer to Figure 1 and Figure 3 A square ring 22 is fitted on the surface of the first fixing band 2. The square ring 22 is used to fix the second fixing band 3 for easy use. Example 2

[0032] refer to Figure 1 and Figure 2A threaded cylinder 10 is threadedly connected to the surface of the fixed tube 1. A fixed ring 11 is rotatably sleeved on the surface of the threaded cylinder 10, and the surface of the fixed ring 11 is bolted to the first fixed band 2 and the second fixed band 3. A support rod 12 is hinged to both the surface of the fixed ring 11 and the surface of the fixed tube 1. A support plate 13 is hinged to the other end of the support rod 12. By rotating the threaded cylinder 10, the threaded cylinder 10 moves. The movement of the threaded cylinder 10 drives the fixed ring 11 to move the support rod 12. The movement of the support rod 12 drives the support plate 13 to move the tooth pads 15. This changes the distance between the tooth pads 15, thereby achieving the purpose of size adjustment, reducing the cost of use, and improving practicality and applicability.

[0033] refer to Figure 1 and Figure 2 The surface of the fixed tube 1 is printed with scale lines 19, which facilitates size adjustment.

[0034] refer to Figure 3 The surface of the threaded cylinder 10 is provided with anti-slip texture 21. By setting the anti-slip texture 21, the hand slips and the operation is facilitated. Example 3

[0038] Brief description of usage: Insert the fixing tube 1 into the patient's mouth, placing the patient's teeth on the dental pad 15. The dental pad 15 supports the teeth and prevents biting. Then, insert the second fixing strap 3 into the fixing head 4 and adjust the second fixing strap 3 to the required tightness. Since the teeth on the locking rack 9 and the locking plate 5 are unidirectional, the locking rack 9 can only be inserted into the fixing head 4 from one side. After adjusting the tightness, the transmission rack 6, under the action of the second spring 24, drives the locking plate 5 to engage with the locking rack 9, thus fixing it in place. To disassemble, press the pressing block 20 to move the bidirectional rack 8. The movement of the bidirectional rack 8 drives the gear 7 to rotate, which in turn causes the transmission rack 6 to move the locking plate 5, disengaging the locking plate 5 from the locking rack 9 and opening it, thus achieving the purpose of fixing. The threaded cylinder 10 rotates, causing it to move. This movement of the threaded cylinder 10 moves the fixed ring 11, which in turn moves the support rod 12. The support rod 12 then moves the support plate 13, which in turn moves the toothed pad 15. This movement of the toothed pad 15 changes its support position, thus achieving the purpose of adjusting the size. Moving the toothed pad 15 causes the mounting rod 14 to move, which in turn moves the limiting head 16. The limiting head 16 retracts under the pressure of the inner wall of the limiting hole 18 and disengages from the limiting hole 18, allowing the toothed pad 15 to be removed and replaced. The mounting rod 14 on the new toothed pad 15 is then inserted into the support plate 13. The limiting head 16 engages with the limiting hole 18 under the action of the first spring 17, fixing it in place, thus achieving the purpose of replacing the toothed pad 15.
