Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a structure for preventing the dislodgement of a general anesthesia tube. Background Technology

[0002] A general anesthesia tube is a special tube used to connect the anesthesia machine to the patient's trachea during general anesthesia. Its main purpose is to ensure that the patient can be effectively ventilated under anesthesia, maintain oxygen balance, protect the airway, and reduce the risks of respiratory depression and aspiration.

[0003] In existing techniques, after exposing the patient's glottis with a laryngoscope, the laryngoscope blade is inserted into the right side of the patient's mouth and gradually moved to the center of the mouth. The tongue is pressed to the left, and the laryngoscope is raised and lowered at a 45-degree angle. After the vocal cords are seen, the endotracheal tube is inserted into the trachea through the mouth under direct vision. The position is usually about 2 cm below the vocal cords. After intubation, the correct position of the tube is confirmed by auscultating breath sounds in both lungs and observing the carbon dioxide monitor. At the same time, the markings on the tube are observed to ensure that the insertion depth is appropriate (about 22-24 cm for men and about 20-22 cm for women). Finally, the tube is fixed to the patient's mouth and nose with adhesive tape to prevent displacement.

[0004] However, in the existing technology, when fixing the catheter, adhesive tape is usually used. In order to ensure stability, a lot of adhesive tape is needed for fixation. This fixation is not only easy to fall off, but also may cause skin tearing or epidermal peeling when removing the tape in some patients with thin or sensitive skin. Therefore, the catheter needs to be fixed quickly.

[0005] Therefore, it is necessary to provide a structure to prevent the general anesthesia tube from slipping out in order to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figures 1-3 As shown, this application provides a structure to prevent the dislodgement of a general anesthesia catheter, including an anesthesia catheter 1, on which an occlusive component 2 is provided. The occlusive component 2 is used by the patient to bite down, specifically:

[0029] The occlusive assembly 2 includes a connecting tube 22 slidably disposed on the anesthesia catheter 1. One end of the connecting tube 22 is provided with an elastic clamp 24. The elastic clamp 24 is composed of multiple sets of elastic plates and forms a circle suitable for the anesthesia catheter 1 to pass through, so that the anesthesia catheter 1 can pass through the interior of the elastic clamp 24. Under the action of external force, the multiple sets of elastic clamps 24 can move closer to each other to clamp the anesthesia catheter 1.

[0030] A sleeve 23 is threaded onto the connecting tube 22. One end of the sleeve 23 has a conical portion 231. The conical portion 231 is fitted onto the outside of the elastic clamp 24. The diameter of the conical portion 231 gradually decreases as it approaches the elastic clamp 24, so that the knob 38 can rotate the sleeve 23 to move the conical portion 231 closer to or away from the elastic clamp 24. When it approaches the elastic clamp 24, it contracts to clamp the anesthesia catheter 1.

[0031] Two sets of connecting blocks 25 are fixedly installed on the connecting tube 22. A first biting block 21 and a second biting block 201 are slidably installed on the connecting block 25, so that the patient can bite the first biting block 21 and the second biting block 201. Both the first biting block 21 and the second biting block 201 have a brim, so that after the patient bites, the brim rests against the outside of the lips or teeth to restrict the two sets of biting blocks.

[0032] Continue to refer to Figure 3 Two sets of inserts 26 are fixedly installed on the second occlusal block 201. These inserts 26 are slidably disposed inside the first occlusal block 21 to allow adjustment of their position within the first occlusal block 21 according to the patient's oral cavity size. Two sets of locking bolts 27 are threaded onto the first occlusal block 21. One end of each locking bolt 27 extends into the first occlusal block 21 and abuts against the inserts 26 to secure them. Figure 3 (Installation and locking state);

[0033] Meanwhile, an anti-dislodgement component 3 is provided on the first occlusal block 21. The anti-dislodgement component 3 prevents the occlusal component 2 from dislodging from the oral cavity. It should be noted that the second occlusal block 201 has the same anti-dislodgement component 3. For ease of explanation, the first occlusal block 21 will be used as an example below.

[0034] like Figures 3-5 As shown, the anti-detachment component 3 includes two sets of rotating rods 32 rotatably installed inside the first biting block 21. The two sets of rotating rods 32 are arranged vertically opposite each other. A knob 38 is fixedly installed at one end of the rotating rod 32 so that rotating the knob 38 can drive the rotating rod 32 to rotate. A disc 33 is fixedly installed at the other end of the rotating rod 32. A cavity 36 adapted to the disc 33 is opened inside the first biting block 21 so that when the rotating rod 32 rotates, it synchronously drives the disc 33 to rotate.

[0035] The disc 33 has an arc groove 34. The end of the arc groove 34 near the rotating rod 32 is the initial end, which is close to the center of the disc 33. At the same time, the end away from the rotating rod 32 is the final end, which is away from the center of the disc 33.

[0036] Furthermore, a round rod (not shown in the figure) is slidably provided inside the end point. A top block 35 is fixedly installed on the round rod. A locking block 31 is provided on the top of the top block 35. A groove 37 adapted to the locking block 31 is provided on the first engaging block 21 so that when the disc 33 rotates, the round rod moves from the end point to the beginning point in the arc groove 34. With the cooperation of the locking block 31 and the groove 37, the locking block 31 retracts into the groove 37.

[0037] It should be noted that in the initial state, the round rod is located at the initial end of the arc groove 34. At this time, the locking block 31 is inside the groove 37, and the locking block 31, the first biting block 21 and the second biting block 201 are all made of elastic material to avoid damaging the patient's oral cavity.

[0038] In summary, during use, after the anesthesia catheter 1 is inserted into the patient's mouth and positioned, rotate the sleeve 23 to move its conical part 231 away from the elastic clamp 24, thus releasing the anesthesia catheter 1. Move the occlusal assembly 2 into the patient's mouth until the brim touches the outside of the lips. At this time, the patient's upper and lower teeth are against the upper and lower surfaces of the two sets of occlusal blocks. Rotate the sleeve 23 again so that the conical part 231 approaches the elastic clamp 24 to clamp and fix the anesthesia catheter 1, thereby preventing the anesthesia catheter 1 from moving inward.

[0039] Then, turn the knob 38 to rotate the rod 32, which in turn moves the rod in the arc groove 34 to the end of the arc groove 34 away from the center of the disc 33. This causes the locking block 31 to extend out of the groove 37 through the fixing block, so that it is located inside the upper and lower teeth. During the operation, when the patient is moved, the locking block 31 can hold against the inside of the upper and lower teeth to prevent the anesthesia catheter 1 from falling out.

[0040] like Figure 3 and Figure 5 As shown, a pin 39 is provided through multiple sets of knobs 38. The pin 39 has threads, and a threaded insertion hole (not shown in the figure) adapted to the pin 39 is opened inside the first engagement block 21. This allows the pin 39 to be inserted into the threaded insertion hole after the locking block 31 extends out of the groove 37, and the knob 38 is fixed by the threads to prevent the knob 38 from rotating accidentally and the pin 39 from coming out when the patient is moved.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
