Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and specifically relates to a mouthpiece suitable for bronchoscopy. Background Technology

[0002] A bronchoscopy is a device used to observe organs such as the lungs. It allows for the analysis of organ samples and can also be equipped with a display screen for direct observation and imaging of organs. The use of a bronchoscopy facilitates the observation and diagnosis of early organ lesions and allows for postoperative organ examination. Currently, during bronchoscopic procedures, the patient needs to bite down on the mouthpiece to fix and protect the bronchoscope. However, prolonged biting of the mouthpiece can easily cause tooth fatigue.

[0003] Existing bronchoscopy mouthpieces, such as the one disclosed in utility model patent CN211355372U, include a channel tube, a shielding panel, an occlusal pad, and a scope tube. An occlusal pad is fixedly installed on the outer side of the channel tube, and an occlusal groove is formed on the outer wall of the occlusal pad. A reservoir cotton is fixedly installed on the side of the occlusal pad, and two reinforcing filter rings are set inside the channel tube. This solves the problems of tooth fatigue, discomfort, and mouthpiece slippage that can easily occur when patients bite down on the bronchoscopy mouthpiece for a long time.

[0004] However, the aforementioned patent still has some defects. Although the bronchoscopy mouthpiece is equipped with a reservoir cotton and a reinforced filter ring to absorb the patient's saliva and prevent it from spraying out, during use, the reservoir cotton is located inside the patient's mouth, and the patient's saliva still accumulates inside the bronchoscopy. Moreover, after a period of time, the more saliva the reservoir cotton absorbs, the more likely it is to overflow, affecting the hygiene and patient comfort during the use of the bronchoscopy. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mouthpiece that is simple in structure, easy to use, and suitable for bronchoscopy.

[0006] The present invention adopts the following technical solution: A mouthpiece suitable for bronchoscopy includes an air intake and a suction mechanism. The air intake includes a baffle that can be fixed to the outside of a patient's mouth, an occlusal tube extending through the baffle, and a fixing strap on the baffle. The suction mechanism is located on the baffle and can be connected to an external negative pressure device to suction saliva out of the patient's mouth. It includes two suction tubes movably mounted on the baffle and located on both sides of the occlusal tube, and two adjusting components mounted on the baffle for adjusting the length and direction of the two suction tubes extending into the patient's mouth. The suction tube includes a connecting section that can be connected to the baffle and a bent section that can extend into the side of the patient's mouth, with the connecting section and the bent section forming an L-shaped bend.

[0007] Furthermore, the suction tube also includes a connector that is detachably connected to the negative pressure device in the connecting section, a spherical head that is located at the end of the bent section and contacts the inner wall of the patient's oral cavity, and multiple side holes on the spherical head.

[0008] Furthermore, the adjustment assembly includes a guide sleeve that passes through the baffle and a rotating buckle that is rotatably disposed on the outside of the baffle adjacent to the guide sleeve. The guide sleeve has an opening section on its side that corresponds to the position of the rotating buckle. The suction tube passes through the guide sleeve, and one side of the rotating buckle abuts against the side of the suction tube exposed in the opening section, so that the suction tube is fixedly connected to the guide sleeve.

[0009] Furthermore, the rotating buckle includes a rotating block that can abut against the side of the suction tube and an arc-shaped groove section provided on the side of the rotating block that is adapted to the outer periphery of the suction tube. The arc-shaped groove section can fit against the outer periphery of the suction tube, so that the suction tube can move back and forth and rotate within the guide sleeve.

[0010] Furthermore, the baffle includes two airbags positioned opposite each other on the inner side of the baffle so as to come into contact with the patient's face, and the airbags are provided with one-way air delivery tubes.

[0011] Furthermore, the occlusal tube includes a connecting part and an occlusal part respectively disposed on the outer and inner sides of the baffle, an occlusal pad disposed on the outer periphery of the occlusal part, and a tongue depressor disposed on the end of the occlusal part and extending outward for fixing the patient's tongue.

[0012] Furthermore, the ventilation mouthpiece also includes an oxygen supply component formed within the occlusal tube. The oxygen supply component includes an annular fixing plate extending from the inner wall of the occlusal tube toward the side near the patient's mouth, an annular groove formed between the annular fixing plate and the inner wall of the occlusal tube, and an air vent disposed on the side of the occlusal tube and communicating with the annular groove. The opening of the annular groove can be opposite to the patient's oral cavity.

[0013] Furthermore, the inner wall of the occlusal tube is provided with a plurality of support columns that are fixedly connected to the annular fixing plate, and the plurality of support columns are located on the side of the annular groove close to the patient's mouth.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, by defining the specific structure of the mouthpiece, adds a suction mechanism to the ventilation mouthpiece. In use, the two suction tubes are fixed to the ventilation mouthpiece through an adjustment mechanism. When the patient bites down on the ventilation mouthpiece, one end of each suction tube can be inserted into the patient's oral cavity, positioned opposite each other on both sides of the oral cavity, and the other end is connected to the negative pressure device. This allows saliva secreted in the patient's oral cavity to be drained into the negative pressure device, preventing saliva from accumulating in the oral cavity and improving the efficiency of bronchoscopy. Hygiene and patient comfort during examination are considered. Specifically, by defining the specific structure of the suction tube, an L-shaped connecting section and a bent section are designed so that when the patient's mouth is opened by the mouthpiece, the two bent sections extend into both sides of the mouth, adapting to the shape of the mouth when the patient is biting. Simultaneously, defining the specific structure of the ventilation mouthpiece allows the baffle and the mouthpiece to be fixed to the patient's head with a fixing strap, ensuring the mouthpiece is stably positioned within the patient's mouth. The bronchoscope is then inserted through the mouthpiece into the patient's body to prevent the patient from biting and damaging the bronchoscope during the examination. By setting a spherical head at the end of the bent section that contacts the inner wall of the patient's mouth, it is possible to avoid puncturing the patient's mouth. By using two airbags that are positioned opposite each other on the inner side of the baffle so that they can contact the patient's face, the two airbags can distribute the force and reduce the pressure of the baffle on the patient's mouth, thus improving the patient's comfort when using the mouthpiece. By using an oxygen supply component formed within the occlusal canal, the ventilation port is connected to the oxygen supply device during the examination, and oxygen is inhaled by the patient through the annular groove, thereby improving the safety of bronchoscopy.

[0022] The present invention will be further described below through specific embodiments.

[0023] like Figures 1 to 6 As shown, this embodiment provides a mouthpiece suitable for bronchoscopy, including an air intake 1 and a suction mechanism 2.

[0024] The ventilation mouthpiece 1 includes a baffle 11 that can be fixed to the outside of the patient's mouth, an occlusal tube 12 that passes through the baffle 11, and a fixing strap 13 that is set on the baffle 11. The fixing strap 13 is an adjustable strap of existing technology with adjustable length, allowing the ventilation mouthpiece 1 to be fitted onto the head of patients of different sizes. Its specific structure will not be further described here. Specifically, in use, the patient first bites down on the occlusal tube 12, and then the fixing strap 13 is used to secure the occlusal tube 12 to the patient's head, ensuring the occlusal tube 12 is stably positioned inside the patient's mouth. A bronchoscope is then inserted into the patient's body through the occlusal tube 12 to prevent the patient from biting and damaging the trachea during the examination. Furthermore, the baffle 11 includes two air cushions 111 disposed opposite to each other on the inner side of the baffle 11 and capable of contacting the patient's face. A one-way air delivery tube 112 is provided on each air cushion 111. When the patient bites down on the mouthpiece, the two air cushions 111 abut against the sides of the patient's cheeks, distributing the force and reducing the pressure of the baffle 11 on the patient's mouth, improving the patient's comfort when using the mouthpiece. The air cushions 111 can be made of flexible material, providing good softness and better protection for the patient. Furthermore, the occlusal tube 12 includes a connecting portion 121 and an occlusal portion 122 respectively disposed on the outer and inner sides of the baffle 11, and a portion disposed outside the occlusal portion 122. The bite pad 123 and the tongue depressor 124 extending outward from the end of the bite portion 122 to fix the patient's tongue are provided. By providing the bite pad 123, the patient can bite more softly, improve the comfort when the teeth contact and bite, and reduce damage to the teeth. Furthermore, the ventilation mouthpiece 1 also includes an oxygen supply component 14 formed in the bite tube 12. The oxygen supply component 14 includes an annular fixing plate 15 extending from the inner wall of the bite tube 12 towards the side near the patient's mouth, an annular groove 16 formed between the annular fixing plate 15 and the inner wall of the bite tube 12, and a groove 16 provided on the side of the bite tube 12 and the annular groove 16. The vent 17 is connected to the patient's mouth, and the opening of the annular groove 16 can be opposite the patient's mouth. During the examination, the vent 17 is connected to the oxygen supply equipment, and oxygen is inhaled by the patient through the annular groove 16, thereby providing oxygen and improving the safety of bronchoscopy. Furthermore, the inner wall of the occlusal tube 12 is provided with multiple support columns 18 that are fixedly connected to the annular fixing plate 15. The multiple support columns 18 are located on the side of the annular groove 16 near the patient's mouth, and the support of the occlusal tube 12 is strengthened by setting multiple support columns 18. Furthermore, the occlusal tube 12, the annular fixing plate 15, the vent 17 and the multiple support columns 18 are integrally formed.

[0025] The suction mechanism 2, mounted on the baffle 11, can be connected to an external negative pressure device to suction saliva out of the patient's mouth. It includes two suction tubes 21 movably mounted on the baffle 11 on either side of the bite tube 12, and two adjusting components 22 mounted on the baffle 11 to adjust the length and direction of the suction tubes 21 extending into the patient's mouth. Each suction tube 21 includes a connecting section 23 that connects to the baffle 11 and a bent section 24 that extends into the side of the patient's mouth, with an L-shaped bend between the connecting section 23 and the bent section 24. When the patient bites down on the ventilation mouthpiece 1, the two suction tubes 21 enter the patient's mouth, and the two bent sections 24 extend into the sides of the mouth. The suction tube 21 is designed to adapt to the shape of the patient's mouth while they are biting down. The connecting section 23 of the suction tube 21 is then connected to a negative pressure device to drain saliva secreted in the patient's mouth into the negative pressure device, preventing saliva buildup and improving hygiene and patient comfort during bronchoscopy. Specifically, the suction tube 21 also includes a detachable connector 25 that connects the connecting section 23 to the negative pressure device, a spherical head 26 at the end of the bent section 24 that contacts the inner wall of the patient's mouth, and multiple side holes 27 on the spherical head 26. The spherical head 26 prevents the suction tube 21 from puncturing the patient's mouth. Furthermore, the adjustment... The segment assembly 22 includes a guide sleeve 28 that passes through the baffle 11 and a rotating buckle 29 that is rotatably disposed on the outside of the baffle 11 adjacent to the guide sleeve 28. The guide sleeve 28 has an opening section 281 on its side that corresponds to the position of the rotating buckle 29. The suction tube 21 passes through the guide sleeve 28, and one side of the rotating buckle 29 abuts against the side of the suction tube 21 exposed in the opening section 281, so that the suction tube 21 is fixedly connected to the guide sleeve 28. Through the cooperation of the guide sleeve 28 and the rotating buckle 29, the length of the suction tube 21 extending into the oral cavity and the position of the bend section 24 can be adjusted to adapt to the oral cavities of different patients. The position improves the practicality of this utility model; further, the rotating buckle 29 includes a rotating block 291 that can abut against the side of the suction tube 21 and an arc-shaped groove section 292 provided on the side of the rotating block 291 that is adapted to the outer periphery of the suction tube 21. Rotating the rotating buckle 29 makes the arc-shaped groove section 292 fit against the outer periphery of the suction tube 21. At this time, the suction tube 21 can move back and forth and rotate within the guide sleeve 28. When the suction tube 21 is fixed within the guide sleeve 28, rotating the rotating buckle 29 makes the side of the rotating block 291 abut against the side wall of the suction tube 21 located in the opening section 281. At this time, the suction tube 21 is fixed within the guide sleeve 28.

[0026] In summary, by utilizing the above-mentioned technical solutions of this utility model, this application, through defining the specific structure of the mouthpiece, adds a suction mechanism 2 to the ventilation mouthpiece 1, which can drain the saliva secreted in the patient's oral cavity into the negative pressure device, avoiding the accumulation of saliva in the oral cavity, thus improving the hygiene and patient comfort during bronchoscopy. Furthermore, by defining the specific structure of the suction tube 21, the suction tube 21, through the L-shaped connecting section 23 and the bent section 24, extends into both sides of the oral cavity when the patient's oral cavity is opened by the mouthpiece, adapting to the shape of the oral cavity when the patient is biting down. Additionally, by defining the specific structure of the ventilation mouthpiece 1, the baffle 11 and the occlusal tube 12 are fixed to the patient's head by the fixing strap 13, thereby ensuring the stability of the occlusal tube 12. Positioned inside the patient's mouth, the bronchoscope is inserted through the bite tube 12 to prevent the patient from biting and damaging the bronchoscope during the examination. Additionally, the spherical head 26, located at the end of the bend 24 and in contact with the inner wall of the patient's mouth, prevents puncture wounds. Furthermore, the two airbags 111, positioned opposite each other on the inner side of the baffle 11 and in contact with the patient's face, distribute pressure and reduce the pressure of the baffle 11 on the patient's mouth, improving comfort when using the mouthpiece. Finally, the oxygen supply component 14, formed within the bite tube 12, connects the ventilation port 17 to an oxygen supply device during the examination, allowing oxygen to be inhaled by the patient through the annular groove 16, thus improving the safety of the bronchoscopy.

[0027] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
