Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, and in particular to a non-destructive protective bite. Background Art

[0002] In the process of diagnosing and treating gastric or lung diseases, endoscopic examination is a routine and important task, which uses an endoscope to directly observe and evaluate the human stomach or lungs. Although endoscopic examination can efficiently and deeply explore the patient's internal conditions, during the examination, medical staff need to operate the endoscope to swing left and right and extend and retract it forward and backward. Since the endoscope enters the patient's mouth, it is easy to collide with the patient's teeth, which may not only damage the endoscope, but also cause the patient's teeth to fall out. There is a risk that the fallen teeth will fall into the human body and cause medical accidents.

[0003] like Fig.14 The figure shows a common bite mouth on the market. When using the above bite mouth to perform endoscopic examination on patients, there are at least the following technical problems: 1) It is easy to knock out the patient's real teeth; among the patients undergoing endoscopic examination, some have dentures, usually one or more dentures. In order to prevent the dentures from falling off and falling into the human body, the dentures need to be removed before the endoscopic examination; after the dentures are removed and placed in the bite mouth, the dentures are in direct contact with the harder outer wall of the bite mouth. When the medical staff operates the endoscope to swing left and right and extend and retract forward and backward, some real teeth that have lost the support of the dentures are at risk of being shaken or shaken out. When the real teeth are shaken or shaken out, it is easy to cause medical disputes, and the shaken dentures are easy to fall into the patient's body and cause medical accidents; 2) The bite mouth is difficult to insert under anesthesia; usually, the bite mouth is inserted before the patient is anesthetized, and complex endoscopic surgeries (such as gastrointestinal mucosal resection, ERCP, small intestine endoscopy, etc.) require endotracheal intubation and general anesthesia. The bite mouth is inserted after the patient is anesthetized to avoid Interference with anesthesia operation; after the patient is anesthetized, the whole body is in an unconscious state. Common bite mouthpieces on the market require the patient's mouth to open a certain size before they can be inserted, and the anesthetized patient needs to use other tools to pry open his mouth, which makes it more difficult to insert the bite mouth; 3) Oral secretions are not easy to clean; after anesthesia, the patient cannot control oral secretions, and the protective reflex is weakened by the influence of anesthesia and muscle relaxants, which can easily cause airway obstruction, tongue prolapse, insufficient ventilation, vomiting and aspiration, and unstable circulatory function; the existing bite mouth structure is not convenient for cleaning oral secretions, generally to control the patient's position. After the patient's examination, there is often a large amount of oral secretions on the examination bed, which requires secondary cleaning; 4) The arc-shaped baffle of the existing bite mouth is easy to damage teeth or gums; in order to prevent the bite mouth from falling into the mouth, a circle of arc-shaped baffles is formed on the outer wall of the front end of the bite mouth. When the bite mouth is placed in the patient's mouth, the hard arc-shaped baffle sometimes rests on the patient's outer gums, and continuous hard friction with the gum root damages the gums.

[0014] As a preferred technical solution, it also includes a guide locking structure, and the guide locking structure includes: a first locking tooth formed on the first guide member and located opposite to the first guide slope; A first locking groove is formed on the end surface of the bite pipe, opposite to the first locking tooth, and is used for matching with the first locking tooth; a second locking tooth formed on the second guide member and located opposite to the second guide slope; A second locking groove is formed on the end surface of the bite pipe, opposite to the second locking tooth, and is used for matching with the second locking tooth.

[0015] As a preferred technical solution, the bite guide is a pair-mounted structure of upper and lower halves, which are detachably fixed by bolts.

[0016] The technical solution provided by the present invention has the following advantages: 1. The damage-free protective bite of the present invention comprises a bite pipe, an arc-shaped baffle, a blocking flange, a fixed slot, a fixing component and a silicone protective cover; wherein the bite pipe is hollow; the arc-shaped baffle is integrally formed on the outer wall of one end of the bite pipe, and the blocking flange is integrally formed on the outer wall of the other end of the bite pipe; there is at least one fixing slot, which is provided on the arc-shaped baffle; the fixing slot has a slot opening connected to the outside; the fixing component is installed inside the fixing slot for fixing the pipe passing through the fixing slot; the silicone protective cover is sleeved on the outer surfaces of the bite pipe and the arc-shaped baffle.

[0017] When using the non-destructive protective bite of the present invention, first put the silicone protective cover on the bite pipe and the arc-shaped baffle, and use the blocking flange to stabilize its position to prevent it from falling off; then gently put the front end of the bite into the patient's mouth, and the patient's teeth naturally bite on the bite pipe covered by the silicone protective cover; finally, accurately install the suction tube in the fixed card slot and lock it with the fixed component to ensure that the pipeline is stable and unobstructed. The non-destructive protective bite of the present invention, the silicone protective cover can effectively buffer the contact between the teeth and the bite pipe, reduce the risk of some real teeth being shaken or shaken off due to the operation of the endoscope, and protect the patient's teeth; the silicone protective cover wraps the arc-shaped baffle to avoid continuous hard friction between the harder arc-shaped baffle and the root of the patient's gums, which can effectively reduce gum damage and improve the safety of use.

[0018] 2. The damage-free protective bite of the present invention has a trapezoidal recess formed on one side of the fixed slot facing the bite pipe, and a protruding block is formed on the arc-shaped baffle opposite to the trapezoidal recess, and the protruding block has a rectangular through hole; the fixing component includes a movable pin that can be movably mounted on the protruding block, a fixed block fixed at one end of the movable pin, and an elastic member sleeved on the movable pin. Through the above structural arrangement, it is possible to directly fix a sputum suction tube on the arc-shaped baffle of the bite. After the sputum suction tube is fixedly mounted on the bite, medical staff can use the sputum suction tube to immediately and effectively clean the secretions in the patient's mouth, thereby avoiding the accumulation of secretions in the mouth, reducing the risk of airway obstruction, tongue prolapse, etc. caused by excessive secretions, and ensuring the smoothness of the patient's respiratory tract.

[0019] 3. The damage-free protective bite of the present invention has a protective sleeve opening on the baffle wrapping section of the silicone protective sleeve, which is opposite to the fixed slot. The design of the protective sleeve opening makes the silicone protective sleeve of the present application compatible with other medical devices, allowing a suction tube or oropharyngeal ventilation tube to be installed in the fixed slot and locked using a fixing component. This design of the present application not only improves the versatility of the bite, but also facilitates medical staff to operate quickly in emergency situations.

The damage-free protective bite of the present invention is also provided with an inner sleeve on the silicone protective sleeve, which is in the shape of a trumpet, with the large end extending toward the direction of the baffle wrapping section, and forming a gap between the inner sleeve and the pipe wrapping section. When the damage-free protective bite of the present application is correctly worn in the patient's mouth, the inner sleeve will naturally unfold in the oral cavity and cover the inside of the teeth. Teeth that accidentally fall out due to surgical operations can be accommodated in the gap between the inner sleeve and the pipe wrapping section, thereby preventing the fallen teeth from falling into the patient's body and avoiding potential medical accidents; this design not only reduces the pressure on medical staff during the operation, but also provides patients with a more secure and comfortable medical experience; By using the non-destructive protective bite with the silicone protective cover added to the present invention, the patient can be prevented from taking out one or more dentures during endoscopic examination, so that the real teeth are supported by the dentures and are not easily shaken or shaken off. Even if the dentures are shaken off during the operation, they will be blocked by the inner stopper and will not fall into the patient's body.

[0021] 5. The non-destructive protective bite of the present invention also includes a bite guide, which includes a guide body, an inverted V-shaped tip and a blocking piece; after the guide body is installed into the inside of the bite pipe, the blocking flange abuts against one end of the bite pipe, and the inverted V-shaped tip can extend from the other end of the bite pipe. The bite guide limits the insertion depth through the blocking piece, and is matched with the bite pipe through the guide locking structure, ensuring the stability of the bite guide during use. The inverted V-shaped tip and guide bevel design of the bite guide adopt a smooth transition, which can more easily penetrate the gap between the patient's lips and teeth and bring the bite into the patient's mouth. Even when the patient is under anesthesia and unconscious, the bite can be smoothly placed, avoiding the risk of damaging the patient's lips and teeth when placing the bite. The design of the bite guide reduces the resistance and difficulty when placing the bite, and improves the efficiency of medical operations. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

[0041] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] This embodiment provides a non-destructive protective bite, such as Figure 1-4 As shown, it includes: a bite pipe 1, an arc-shaped baffle 2, a blocking flange 3, a fixed slot 4, a fixing component and a silicone protective cover 5; wherein the bite pipe 1 is hollow; the arc-shaped baffle 2 is integrally formed on the outer wall of one end of the bite pipe 1; the blocking flange 3 is integrally formed on the outer wall of the other end of the bite pipe 1; there is at least one fixing slot 4, which is opened on the arc-shaped baffle 2; the fixing slot 4 has a slot opening 040 connected to the outside; the fixing component is installed inside the fixing slot 4, and is used to fix the pipe passing through the fixing slot 4; the silicone protective cover 5 is sleeved on the outer surfaces of the bite pipe 1 and the arc-shaped baffle 2.

[0043] When using the non-destructive protective bite of this embodiment, first put the silicone protective cover 5 on the bite pipe 1 and the arc-shaped baffle 2, and use the blocking flange 3 to stabilize its position to prevent it from falling off; then gently put the front end of the bite into the patient's mouth, and the patient's teeth naturally bite on the bite pipe 1 covered by the silicone protective cover 5; finally, accurately install the sputum suction tube in the fixed card slot 4, and lock it with the fixed component to ensure that the pipeline is stable and unobstructed. In the non-destructive protective bite of the present invention, the silicone protective cover 5 can effectively buffer the contact between the teeth and the bite pipe 1, reduce the risk of some real teeth being shaken or shaken off due to the operation of the endoscope, and protect the patient's teeth; the silicone protective cover 5 wraps the arc-shaped baffle 2, avoiding the continuous hard friction between the harder arc-shaped baffle and the root of the patient's gums, which can effectively reduce the risk of gum damage and improve the safety of use.

[0044] like Figure 5 and Figure 6 As shown, a trapezoidal recess 041 is formed on the side of the fixed slot 4 facing the bite pipe 1, and a protruding block 021 is formed on the arc-shaped baffle 2 opposite to the trapezoidal recess 041, and the protruding block 021 has a rectangular through hole 022; the fixing assembly includes: a movable bayonet 6, a fixed block 061 and an elastic member 064; wherein, the movable bayonet 6 is movably installed inside the rectangular through hole 022, and one end located outside the fixed slot 4 has a bayonet stopper 060; the part of the movable bayonet 6 located inside the rectangular through hole 022 is rectangular; the fixed block 061 is fixed to one end of the movable bayonet 6 located inside the fixed slot 4, and has an arc-shaped notch 062 that can match the trapezoidal recess 041; the elastic member 064 is sleeved on the movable bayonet 6, one end of which abuts against the fixed block 061, and the other end abuts against the inner side surface of the protruding block 021.

[0045] When an external force is used to pull the pin stopper 060 outward, the elastic member 064 is compressed, the movable pin 6 moves outward, and the arc-shaped notch 062 of the fixed block 061 moves in a direction away from the trapezoidal recess 041; after the external force disappears, the elastic member 064 stretches, driving the fixed block 061 to move in a direction close to the trapezoidal recess 041, thereby fixing the pipeline between the arc-shaped notch 062 and the trapezoidal recess 041.

[0046] The above structural setting can realize the direct installation of the suction tube on the arc-shaped baffle of the bite mouth. After the suction tube is installed on the bite mouth, the medical staff can use the suction tube to immediately and effectively clean the secretions in the patient's mouth, thereby avoiding the accumulation of secretions in the mouth, reducing the risks of airway obstruction and tongue prolapse caused by excessive secretions, and ensuring the smoothness of the patient's respiratory tract.

[0047] Preferably, an anti-slip texture is provided on the inner side surface of the arc-shaped notch 062, and an anti-slip texture is also provided on the inner side surface of the trapezoidal recess 041 opposite to the arc-shaped notch 062, so that the pipeline can be fixed more firmly.

[0048] A rectangular groove 023 that can match the fixed block 061 is formed on one side of the protruding block 021 facing the fixed slot 4; a section of the rectangular through hole 022 facing the fixed slot 4 is formed as a circular hole 024 for installing the elastic member 064. The design of the rectangular groove 023 and the circular hole 024 allows part of the fixed block 061 to enter the rectangular groove 023 when the pipeline is installed downward from the slot opening 040, leaving the slot opening 040 as far as possible to facilitate pipeline installation; preferably, the two ends of the arc-shaped notch 062 on the fixed block 061 form an arc transition, which can also facilitate the pipeline to enter from this position.

[0049] like Figure 7 and Figure 8 As shown, the silicone protective cover 5 includes: a pipe wrapping section 050 and a baffle wrapping section 051; wherein the pipe wrapping section 050 is suitable for being sleeved and wrapped around the outside of the bite pipe 1; the baffle wrapping section 051 is integrally connected with one end of the pipe wrapping section 050, suitable for being sleeved and wrapped around the outside of the arc-shaped baffle 2, and is provided with a protective cover opening 052 opposite to the fixed card slot 4, and a protective cover through hole 053 opposite to the rectangular through hole 022; the baffle wrapping section 051 includes a wrapping sheet 054 that is in contact with the inner side surface of the arc-shaped baffle 2 and a flexible edging 055 formed on the edge of the wrapping sheet 054 and suitable for wrapping the edge of the arc-shaped baffle 2. A protective cover opening 052 is provided on the baffle wrapping section 051 of the silicone protective cover 5; the design of the protective cover opening 052 enables the silicone protective cover 5 of the present application to be compatible with other medical devices, allowing a suction tube or an oropharyngeal ventilation tube to be accurately installed in the fixed card slot 4, and locked with a fixed component to ensure stability; this design of the present application not only improves the versatility of the bite, but also facilitates quick operation by medical staff in emergency situations.

[0050] like Figure 7 and Figure 8As shown, the silicone protective sleeve 5 also includes an inner stop sleeve 056, which is in a bell-mouth shape. The small end of the inner stop sleeve 056 is integrally formed with the end of the pipe wrapping section 050 that contacts the inner side of the blocking flange 3, and the large end extends toward the blocking piece wrapping section 051, and a gap is formed between the inner stop sleeve 056 and the pipe wrapping section 050. When the damage-free protective bite of the present application is correctly worn in the patient's mouth, the inner stopper 056 will naturally unfold in the oral cavity and cover the inside of the teeth. Teeth accidentally falling out due to surgical operations can be accommodated in the gap between the inner stopper 056 and the pipe wrapping section 050, thereby preventing the fallen teeth from falling into the patient's body and avoiding potential medical accidents. This design not only reduces the pressure on medical staff during the operation, but also provides patients with a more secure and comfortable medical experience. When using the damage-free protective bite with a silicone protective cover 5 added to the present invention, the patient can be prevented from removing one or more dentures during endoscopic examination. In this way, the real teeth are supported by the dentures and are not easily shaken or shaken off. Even if the dentures are shaken off during the operation, they will be blocked by the inner stopper and will not fall into the patient's body.
