Description

Technical Field

[0001] This invention relates to the field of medical bite plate technology, and in particular to a non-loosening double-port endoscope bite plate compatible with high-flow oxygen therapy. Background Technology

[0002] In clinical practice, endoscope bites are indispensable auxiliary instruments during endoscopic procedures such as bronchoscopy and gastroscopy. Their core functions are to maintain an open mouth, secure the endoscopic catheter, prevent the patient from biting and damaging the endoscopic instruments, and ensure a clear access route. Current endoscopic bites are mostly of a single structural design with limited functionality, making them unsuitable for the clinical need to simultaneously perform high-flow oxygen therapy and endoscopic procedures. When patients require high-flow oxygen therapy during endoscopic procedures, traditional bites cannot achieve a proper layout of the oxygen tubing and endoscopic catheter, easily leading to tubing entanglement, interference with the procedure, and compromising the effectiveness of oxygen supply. In bronchoscopy procedures, existing techniques have two significant drawbacks in insertion methods: Nasal insertion, due to the thin nasal mucosa and dense capillaries, easily causes mucosal friction damage and bleeding during insertion and movement of the bronchoscope catheter. In severe cases, it can lead to nasal edema and infection, increasing patient suffering and the risk of clinical complications. Oral insertion, due to the vast space and complex structure of the oral cavity, traditional bite blocks lack effective endoscopic fixation structures, failing to securely limit the bronchoscope catheter. The catheter is prone to displacement and wobbling, affecting operational accuracy and potentially leading to errors and delays in treatment. Furthermore, patients often require anesthesia during endoscopic procedures. After anesthesia, the tongue base is prone to posterior displacement, compressing the airway and causing upper airway obstruction. Even with high-flow nasal cannula oxygenation, oxygen cannot effectively pass through the obstructed airway to reach the lungs, failing to maintain adequate blood oxygen saturation and easily leading to serious clinical risks such as hypoxia and asphyxia.

[0003] Furthermore, during high-flow oxygen therapy, traditional equipment lacks effective flow regulation and pressure relief mechanisms. When large-flow oxygen is directly infused into the patient's lungs and stomach, it can easily lead to lung overinflation and gastric bloating. In severe cases, it may even cause respiratory alkalosis, threatening the patient's life. Moreover, traditional oxygen therapy equipment cannot monitor the patient's respiratory status in real time. When a patient loses spontaneous breathing under high-flow oxygen therapy, medical staff may find it difficult to detect quickly, which can easily lead to missed diagnoses and serious medical safety accidents.

[0004] Existing invention patent CN 114984391 A discloses a high-flow ventilator for preventing and treating hyperventilation, comprising an installation body, on which a ventilator body is mounted. The ventilator body's air inlet is connected to an air source, a high-pressure oxygen source, and a carbon dioxide source, and the ventilator body's air outlet is connected to a face mask. This invention addresses the technical problem of hyperventilation (excessive carbon dioxide exhalation) frequently occurring during patient use with existing high-flow ventilators, which can cause symptoms such as chest tightness, chest pain, palpitations, and tachycardia.

[0005] Meanwhile, an invention patent with publication number WO2018152661A1 discloses a medical mouthpiece, which is integrally molded for the user to bite and insert into the user's mouth. The mouthpiece includes a through channel, an upper occlusal groove, and a lower occlusal groove. The mouthpiece is inserted through the through channel, which has an entrance opening at one end and an oral cavity opening at the other end for connecting to the user's oral cavity. The upper occlusal groove is recessed on the upper surface of the mouthpiece, and the lower occlusal groove is recessed on the lower surface of the mouthpiece. The lower occlusal groove is for the lower teeth to bite, and the upper occlusal groove is for the upper teeth to bite. The distance between the lower occlusal groove and the oral cavity opening is greater than the distance between the upper occlusal groove and the oral cavity opening, so the user's lower jaw can be extended forward and the user's upper jaw and lower jaw are misaligned.

[0006] However, because the aforementioned bite plate adopts a fixed one-piece design, it cannot be adaptively adjusted according to the needs of patients of different ages and oral sizes. Adults and children, as well as patients with large differences in body size, need to be equipped with bite plates of different sizes, which increases the cost of clinical equipment reserves and management difficulty. At the same time, the aforementioned exhalation device has a complex structure, occupies a large area, and is not easy to operate. Furthermore, the fixed bite plate cannot form a stable engagement with the patient's oral cavity wall and teeth. During operation, the bite plate is prone to fall off due to the patient's unconscious movements, requiring medical staff to make repeated adjustments, which increases the workload of medical staff and also affects the efficiency of operation. Summary of the Invention

Detailed Implementation

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] Reference Figure 1-8 This is the first embodiment of the present invention, which provides a non-loosening double-port endoscope bite that is compatible with high-flow oxygen therapy, and includes cost savings.

[0043] Specifically, it includes: a bite plate 100, which is used to be inserted into and engage with the patient's mouth; the bite plate 100 has at least two through holes 101, and a knob 102 is detachably installed inside each through hole 101; and,

[0044] The oropharyngeal tube 200 and the airway tube 201 are detachably disposed inside the through hole 101 via the knob 102.

[0045] The airway tube 201 is a liquid silicone tube used to simulate the internal environment of the nasal cavity. When the knob 102 is rotated, the airway tube 201 is compressed.

[0046] It also includes a high-flow oxygen tube 300, one end of which is provided with a nasal inlet 301. The outer wall of the high-flow oxygen tube 300 is also provided with a branch tube 302, which is used to divert oxygen to the glottis. When high-flow oxygen is delivered, the oropharyngeal tube 200 is used to push open the tongue root and relieve airway obstruction.

[0047] In the prior art, a bronchoscope is inserted through the nasal cavity, passes through the glottis, and enters the trachea. However, the nasal cavity wall is rich in capillaries, which can easily cause tissue damage and bleeding. If it is inserted through the oral cavity, it is difficult to stably fix the bronchoscope due to the large space in the oral cavity. In this invention, the airway tube 201 and the oropharyngeal tube 200 can be detachably set on the through hole 101 by the knob 102, so as to match the application scenarios of gastroscopy and bronchoscope respectively according to the needs of the site.

[0048] The airway tube 201 is made of medical silicone, which is relatively soft. After the bronchoscope is inserted into the airway tube 201, compressing the airway tube 201 can simulate the shape inside the nasal cavity and fix the bronchoscope at the same time. The adaptive fixation adjustment can be achieved by rotating the knob 102.

[0049] Preferably, in this embodiment, the through hole 101 and the knob 102 are detachably connected by a snap fastener. In other embodiments, the through hole 101 and the knob 102 can also be connected by a thread (not shown in the figure). The inner wall of the knob 102 is provided with three elastically deformable plastic claws arranged in a circumferential array. The inner wall of the through hole 101 is provided with a chamfer. When the knob 102 gradually screws into the through hole 101, it also moves forward continuously. At this time, the three plastic claws slide along the chamfer and are forced to move towards the axis of the through hole 101, thereby abutting against the inner wall of the airway tube 201 and deforming it, thereby simulating the internal space of the nasal cavity of patients of different ages, and realizing the adaptive adjustment and fastening of the airway tube 201, which is compatible with multiple usage scenarios.

[0050] Even better, when the patient's tongue may fall back after anesthesia, causing upper airway obstruction, even if high-flow nasal cannula oxygen is administered, oxygen cannot be inhaled. The oropharyngeal tube 200 in this invention is an oropharyngeal airway. When it is inserted into the oropharyngeal region, it can pry open the fallen tongue, thereby relieving airway obstruction and ensuring normal oxygen supply from the high-flow oxygen tube 300.

[0051] In this invention, the branch pipe 302 is connected to the high-flow oxygen pipe 300 and the oropharyngeal tube 200 respectively. At the same time, the inner diameter of the branch pipe 302 is much smaller than that of the high-flow oxygen pipe 300, so that a small portion of the oxygen flow can enter the glottis of the oropharyngeal region through the branch pipe 302 and the oropharyngeal tube 200, thereby improving the oxygen supply efficiency.

[0052] Even better, when the high-flow oxygen tube 300 is supplying oxygen at a high flow rate, it may cause a large flow of oxygen to enter the lungs or stomach, causing personal injury. In this case, the branch tube 302 and the oropharyngeal tube 200 can serve as backup air outlet channels to relieve pressure and avoid secondary injury.

[0053] Furthermore, while high-flow oxygen therapy can effectively maintain the patient's blood oxygen saturation and prevent a drop in blood oxygen, this intervention can easily lead to missed diagnoses if the patient loses spontaneous breathing. If only oxygen therapy is used to maintain normal blood oxygen levels while the patient has no spontaneous breathing for a long period of time, it will cause serious clinical risks. This invention can monitor the exhaled carbon dioxide concentration at the glottis through an oropharyngeal tube 200, providing doctors with real-time data references and avoiding symptoms such as respiratory alkalosis.

[0054] This technical solution, through a modular design that integrates the bite plate 100, oropharyngeal tube 200, airway tube 201, and high-flow oxygen tubing 300, addresses several technical challenges in clinical bronchoscopy and high-flow oxygen therapy. It also enhances clinical safety monitoring during oxygen therapy, comprehensively improving operational adaptability, oxygen supply effectiveness, and clinical application safety. Specific beneficial effects are as follows:

[0055] ①. Achieving flexible adaptation and stable instrument fixation for multiple clinical scenarios, avoiding nasal cavity operation injuries, the through hole 101 on the bite 100, together with the detachable knob 102, allows for flexible assembly and disassembly of the oropharyngeal tube 200 and airway tube 201 according to different application needs of gastroscopy and bronchoscopy. The airway tube 201 is made of medical-grade liquid silicone material, which can be adaptively compressed by rotating the knob 102 to simulate the internal space of the nasal cavity of patients of different ages. This not only achieves a tight fixation of the bronchoscope, solving the problem of unstable instrument fixation when inserting the endoscope through the mouth, but also avoids the clinical drawbacks of traditional nasal insertion of the bronchoscope, which can easily cause mucosal capillary damage and bleeding. Furthermore, the connection method between the knob 102 and the through hole 101, combined with the structural design of the elastic plastic claw on the inner wall of the knob 102, allows for precise adjustment and stable fixation of the airway tube 201, compatible with the usage needs of multiple ages and operating scenarios.

[0056] ②. Relieve upper airway obstruction and ensure the patency of the high-flow oxygen therapy channel. The oropharyngeal tube 200 can effectively push open the tongue base of the patient after anesthesia, relieve the upper airway obstruction problem, and avoid the oxygen supply failure caused by airway obstruction when using traditional high-flow nasal cannula oxygen delivery. It establishes a smooth airway for the oxygen supply operation of the high-flow oxygen tube 300 and ensures the effective implementation of high-flow oxygen therapy.

[0057] ③. Optimize oxygen supply efficiency and construct a pressure relief protection mechanism to prevent secondary injury. The high-flow oxygen tube 300 has a branch tube 302 on its outer wall, which is connected to the oropharyngeal tube 200. The branch tube 302 can divert oxygen to the glottis, effectively improving the overall oxygen supply efficiency. At the same time, the branch tube 302 and the oropharyngeal tube 200 form a backup air outlet channel, which can effectively release the excess pressure when the high-flow oxygen tube 300 supplies oxygen at high flow rate, avoiding personal injury caused by the direct infusion of large flow oxygen into the patient's lungs and stomach. Structurally, it avoids the risk of secondary injury during the oxygen supply process.

[0058] ④ By adding respiratory-related clinical monitoring dimensions, hidden clinical risks during oxygen therapy are avoided. The oropharyngeal tube 200 can monitor the exhaled carbon dioxide concentration at the glottis in real time, providing accurate respiratory status data for clinical reference. It can effectively identify the hidden situation of patients losing spontaneous breathing under oxygen therapy with high-flow oxygen tube 300. It solves the technical problems of traditional high-flow oxygen therapy, which can only maintain blood oxygen saturation and is prone to missing patients without spontaneous breathing. It not only avoids the serious clinical risk of patients not breathing spontaneously for a long time and relying solely on oxygen therapy to maintain blood oxygen, but also effectively prevents the occurrence of respiratory alkalosis and other related diseases, thus improving the clinical safety of high-flow oxygen therapy.

[0059] ⑤. The overall structure adopts a modular and detachable design, which improves the convenience of clinical operation. The bite 100, knob 102, oropharyngeal tube 200 and airway tube 201 are all detachable. Each component can be quickly selected, disassembled and adjusted according to clinical needs. The operation is simple and highly adaptable, which can effectively improve the efficiency of clinical operation and reduce the operation difficulty for medical staff.

[0060] Example 2

[0061] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that people of different ages have different oral cavity volumes and need to adapt to different sizes of tracheas. In this embodiment, the bite plate 400 can swing according to the size of the oral cavity to achieve adaptive adjustment and fixation of the bite and trachea.

[0062] Specifically, a bite tube 401 and a bite plate 400 are respectively provided on one side of the bite opening 100. There are two bite plates 400, which are symmetrically arranged on both sides of the bite tube 401. An arc plate 402 is slidably provided on the bite plate 400. The bite plate 400 is rotatably set on the bite opening 100. After the patient's lips and teeth are engaged in the bite opening 100, they push the arc plate 402 to move. When the arc plate 402 slides, it drives the bite plate 400 to swing synchronously.

[0063] The biting tube 401 penetrates the biting opening 100 and is hollow inside, allowing a lighting lamp or suction tube to be inserted. The biting plate 400 is symmetrically arranged on both sides of the biting tube 401. In the prior art, the biting plate 400 is fixedly arranged, while in this embodiment, the biting plate 400 is rotatably arranged on the outer wall of the biting opening 100.

[0064] Among them, such as Figure 4 As shown, a groove 4001 is provided on the bite plate 400, and a slide table 4002 is slidably provided on the outer wall of the bite tube 401. A connecting rod 4003 is provided on the upper end face of the slide table 4002. The connecting rod 4003 slidably passes through the groove 4001 and is connected to the bottom surface of the arc plate 402.

[0065] Even better, a slope 4004 is fixedly provided on the outer wall of the biting plate 400 away from the arc plate 402, and a roller 4005 is rotatably provided inside the connecting rod 4003, with rollers 4006 provided on both sides of the roller 4005.

[0066] Furthermore, such as Figure 5 As shown, the roller 4006 is slidably attached to the outer wall of the slope 4004. The slope 4004 is an inclined slope. The side of the slope 4004 closer to the bite 100 is close to the bite tube 401, and the side of the slope 4004 away from the bite 100 is away from the bite tube 401. As a result, when the roller 4006 moves towards the bite 100, it also moves upward along the slope 4004 at the same time, which eventually drives the bite plate 400 to swing upward, causing the two bite plates 400 to expand outward and open the mouth.

[0067] The biting plates 400 are symmetrically arranged on the upper and lower sides of the bite tube 401, respectively contacting the upper and lower lips and teeth of the patient's mouth. In the initial state, the two biting plates 400 are close to each other on the side away from the bite opening 100, so as to facilitate the patient to insert the bite opening.

[0068] More preferably, a limiting groove 4007 is provided on the bite plate 400. The limiting groove 4007 is a parallelogram and is inclined towards the bite 100. The limiting groove 4007 engages with the patient's teeth when the bite plate 400 is parallel.

[0069] Among them, such as Figure 6 As shown, when the bite plate 400 is in the initial tilted state, the teeth can slide across the limiting groove 4007 and move closer to the bite 100. When the bite plate 400 swings and expands to the horizontal state, one side of the outer wall of the limiting groove 4007 engages with the inner wall of the teeth to prevent the bite 100 from falling off and to ensure the fixation effect.

[0070] Preferably, a chamber 4008 is also fixedly provided on the bite plate 400, a slide plate 4009 is slidably provided inside the chamber 4008, and a slide rod 4011 is provided on the outer wall of the slide plate 4009;

[0071] A limiting plate 4012 is provided between the arc plate 402 and the cabin 4008. A first elastic element 4013 is provided between the limiting plate 4012 and the slide 4009. An indicator rod 4014 is also provided at one end of the slide 4009. An indicator code is provided at one end of the indicator rod 4014 that extends through to the outside of the bite 100.

[0072] The first elastic element 4013 is a spring that constantly pushes the slide plate 4009 to move away from the bite plate 100, thereby allowing the arc plate 402 and bite plate 400 to automatically return to their initial state. The indicator rod 4014 consists of two rods connected by a universal joint. The outer wall of the end of the indicator rod 4014 that extends to the outside of the bite plate 100 is marked with "S", "X", and "XL", representing small, medium, and large oral cavity spaces, respectively. The appropriate size bronchoscope tube is selected according to the markings. The greater the travel of the arc plate 402 and the indicator rod 4014, the larger the oral cavity space, and the larger the size of the selected bronchoscope tube can be.

[0073] In use, the bite plates 400, which are symmetrically arranged on both sides of the bite tube 401, are close to each other in the initial state, so as to facilitate insertion into the oral cavity. The roller 4006 is in contact with the initial position of the slide 4004, and the indicator rod 4014 does not display the initial mark at this time. After the bite 100 is inserted into the patient's oral cavity, the patient's lips and teeth push the arc plate 402 to move axially, which drives the connecting rod 4003 to slide along the slide groove 4001. The roller 4006 moves along the slope of the slide 4004 towards the bite 100 and moves upward, pulling the upper and lower bite plates 400 to swing outward to a horizontal state, thus completing the adaptive opening of the patient's oral cavity.

[0074] At this time, the parallelogram limiting groove 4007 on the bite plate 400 engages with the inner wall of the patient's teeth, thus fixing the bite 100 and preventing it from falling out. At the same time, the movement of the arc plate 402 drives the slide plate 4009 and the indicator rod 4014 to move synchronously. Medical staff can determine the patient's oral cavity space specifications and select the appropriate bronchoscope tube according to the "S", "X" and "XL" markings on the outside of the indicator rod 4014.

[0075] In summary, this invention significantly improves the convenience, stability, and fitting accuracy of the bite plate in clinical applications, meeting the needs of clinical scenarios such as bronchoscopy. It enables convenient insertion of the bite plate into the patient's oral cavity, effectively reducing the difficulty of bite plate fitting and improving the efficiency of the initial clinical procedures. The patient's own movements allow for adaptive opening of the oral cavity, eliminating the need for manual adjustment by medical staff, greatly simplifying the oral cavity opening process and reducing the workload for medical personnel. Simultaneously, it ensures a secure fixation between the bite plate and the patient's oral cavity, effectively preventing bite plate dislodgement during clinical procedures and providing a stable foundation for subsequent operations. Furthermore, it allows for precise visual determination of the patient's oral cavity dimensions, providing an intuitive reference for selecting the appropriate bronchoscopy tube size, achieving precise fitting between the instrument and the patient's oral cavity conditions, avoiding oral tissue damage caused by incompatible instrument sizes, and significantly improving the safety of clinical procedures and the accuracy of instrument selection.

[0076] Example 3

[0077] Reference Figure 1-8 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the flow rate of high-flow oxygen can also be adjusted synchronously.

[0078] Specifically, the chamber 4008 is slidably sealed with the indicator rod 4014 and the slide plate 4009. The chamber 4008 is filled with a medium, and the outer wall of the chamber 4008 is also connected to a pressure-balancing pipe 4015.

[0079] Among them, a spherical bag 3001 is provided at the air inlet end of the high flow oxygen tube 300, and an adjusting barrel 3002 is slidably provided on the inner wall of the high flow oxygen tube 300. An air groove 3003 is provided on the adjusting barrel 3002. When the adjusting barrel 3002 moves, it causes the air groove 3003 and the area connected to the spherical bag 3001 to change synchronously.

[0080] Furthermore, the regulating barrel 3002 is closed at one end inside the spherical bag 3001 and open at the other end inside the high-flow oxygen tube 300. The greater the range of movement of the regulating barrel 3002, the larger the area of ​​the gas trough 3003 entering the spherical bag 3001, and the greater the gas flow rate that can pass through.

[0081] The regulating tank 3002 can be equipped with a heater to compensate for the temperature drop caused during the transmission process, so that the high-speed oxygen flow can maintain the optimal temperature.

[0082] More preferably, one end of the adjusting barrel 3002 is provided with a transmission plate 3004, an adjusting rod 3005 is provided through the spherical bladder 3001, an adjusting column 3006 is provided on the outer wall of the adjusting rod 3005, and an adjusting groove 3007 is provided on the transmission plate 3004.

[0083] The adjusting column 3006 is located inside the spherical capsule 3001, which is made of rigid plastic. One end of the spherical capsule 3001 is connected to the high-flow oxygen tube 300, and the other end is connected to the oxygen supply tube. The adjusting column 3006 slides through the spherical capsule 3001 and is slidably located inside the adjusting groove 3007.

[0084] Preferably, such as Figure 8 As shown, when the adjusting column 3006 slides downward, it pushes the transmission plate 3004 to slide to the right, thereby increasing the gas flow rate.

[0085] More preferably, the adjusting rod 3005 has a sealing plate 3008 at one end that passes through the spherical bladder 3001, and a sealing cavity 3009 is fixedly provided on the outer wall of the spherical bladder 3001, with the sealing plate 3008 slidably disposed on the inner wall of the sealing cavity 3009.

[0086] One end of the pressure-regulating tube 4015 is connected to the sealed cavity 3009, and the other end of the adjusting rod 3005, which passes through the spherical bladder 3001, is provided with a dial 3011, which is used to characterize the oxygen flow rate.

[0087] The constant pressure tube 4015 has a much smaller diameter than the high-flow oxygen tube. The medium filled inside the chamber 4008 can be incompressible media such as water or oil. When the chamber 4008 is compressed by the moving slide plate 4009, the medium enters the sealing cavity 3009 along the constant pressure tube 4015 and pushes the sealing plate 3008 downward. At the same time, the transmission plate 3004 is displaced by the adjusting column 3006, thereby adjusting the oxygen intake. Meanwhile, the scale 3011 moves outward synchronously with the same amplitude. The more the scale 3011 extends beyond the spherical bag 3001, the larger the scale value, indicating a larger oxygen flow. This realizes the function of automatically matching the recent oxygen flow based on the size of the patient's mouth and trachea, avoiding respiratory alkalosis caused by high-flow oxygen.

[0088] In other embodiments, the adjusting column 3006 can be controlled by a cylinder that adjusts its stroke according to the glottic carbon dioxide concentration collected by the oropharyngeal airway, thereby detecting in real time whether the patient has a long-term lack of spontaneous breathing.
