[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a visible light stick cannula tooth pad. Background Art

[0002] For beginners and inexperienced doctors, when using the visible light stick for intubation, the lens of the visible light stick is easily contaminated by the saliva of the patient's tongue, resulting in the lens being unable to clearly and accurately see the position of the visible light stick and the lens, making it inconvenient to intubate the patient. Utility Model Content

[0003] The utility model aims to provide a visible light stick cannulation dental pad to solve the technical problem that beginners or inexperienced doctors cannot accurately cannulate with a visible light stick.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] The utility model discloses a visible light stick cannula tooth pad, comprising:

[0006] A tooth pad assembly, wherein the tooth pad assembly is provided with a bite portion for the patient's teeth to bite, and the bite portion is hollow to form a guide cavity for the visible light rod to be inserted;

[0007] A tongue depressor assembly is connected to the occlusal portion, the tongue depressor assembly is provided with a guide groove opening upward, the guide groove receives and conducts the guide cavity, and the tongue depressor assembly extends downward in an arc shape away from the occlusal portion so that when the patient bites on the occlusal portion, the tongue depressor assembly is inserted in front of the patient's epiglottis.

[0008] The utility model has at least the following beneficial effects: the visible light stick cannula tooth pad is inserted into the oropharynx of the patient, and the tooth pad assembly includes a bite portion, so that the patient bites on the bite portion and keeps the bite open, which facilitates the insertion of the visible light stick and the cannula into the guide cavity and avoids the visible light stick from contacting the patient's teeth and contaminating the lens of the visible light stick.

[0009] The tongue depressor assembly is connected to the occlusal part so that the upward opening guide groove on the tongue depressor assembly receives and conducts the guide cavity, allowing the visible light rod to enter the guide groove along the guide cavity to prevent the visible light rod from contacting the patient's tongue, thereby causing the lens of the visible light rod to be contaminated by saliva. The visible light rod reaches the front of the patient's epiglottis along the guide groove, making it convenient for the doctor to perform tracheal intubation according to the epiglottis position of the lens. The tongue depressor assembly is also used to depress the tongue to prevent the tongue from falling back in anesthetized patients or comatose patients due to relaxation of the floor of the mouth and pharyngeal muscles.

[0010] As a further improvement of the above technical solution, the guide cavity is funnel-shaped and gradually decreases toward the tongue depressor assembly.

[0011] Through the above-mentioned arrangement, one end of the funnel-shaped guide cavity has a large opening, which is convenient for the doctor to quickly insert the endotracheal tube and the visible light stick inside it into the guide cavity; the end of the guide cavity facing the tongue depressor assembly has a small opening to reduce and limit the insertion position of the visible light stick, so that the visible light stick and the endotracheal tube can be accurately inserted into the patient's oropharynx, avoiding the deviation of the visible light stick and the endotracheal tube, and saving insertion and adjustment time.

[0012] As a further improvement of the above technical solution, the guide cavity is provided with a limiting hole for connecting with the guide groove, and the limiting hole is located in the middle of the end of the bite portion connected to the tongue depressing assembly.

[0013] Through the above arrangement, the visible light rod can accurately enter the guide groove through the limiting hole. The limiting hole is located in the middle of the occlusal portion connected to one end of the tongue depressor assembly, so that the visible light rod can be accurately inserted from the midline of the patient's oropharynx.

[0014] As a further improvement of the above technical solution, the limiting hole is a circular hole with a diameter of 11 mm.

[0015] Through the above arrangement, the limiting hole can allow endotracheal tubes of various specifications to pass through, thereby improving the applicability of the visible light stick intubation tooth pad.

[0016] As a further improvement of the above technical solution, the guide groove is a semicircular groove with an inner diameter of 12 mm, so that the guide groove receives and semi-surrounds the lower end of the limiting hole.

[0017] Through the above arrangement, the guide groove is a semicircular groove with the opening facing upward, so that when the guide groove receives the guide cavity, it can half-surround the lower end of the limiting hole, so that the visible light rod passed through the tracheal tube can continue to be inserted into the oropharynx of the patient along the guide groove. The semicircular guide groove can further prevent the visible light rod and the tracheal tube from being offset during the insertion process.

[0018] As a further improvement of the above technical solution, the tongue depressing assembly is flat, and the guide groove is arranged in the middle of the upper end of the tongue depressing assembly.

[0019] Through the above arrangement, the flat tongue depressor assembly can increase its contact area with the tongue, allowing it to better depress the tongue. The guide groove is located in the middle of the upper end of the tongue depressor assembly, so that the visible light stick can be accurately inserted into the patient's oropharyngeal midline when inserted along the guide groove.

[0020] As a further improvement of the above technical solution, the arc-shaped extension length of the tongue depressor assembly is between 6 cm and 8 cm.

[0021] Through the above arrangement, it is ensured that the extension length of the tongue depressor assembly is sufficient to allow the visible light rod and the tracheal cannula to be inserted along the guide groove to the front of the patient's epiglottis.

[0022] As a further improvement of the above technical solution, the tooth pad assembly is provided with a baffle, and the baffle is connected to an end of the occlusal portion away from the tongue depressor assembly.

[0023] Through the above arrangement, the baffle is used to abut against the patient's lips to limit the insertion depth of the visible light stick insertion tooth pad, thereby preventing the visible light stick insertion tooth pad from being inserted too deeply into the patient's oropharynx, causing discomfort to the patient.

[0024] As a further improvement of the above technical solution, the guide cavity is provided with an insertion hole for penetrating the baffle, and the insertion hole extends in a horizontal direction perpendicular to the guide cavity.

[0025] Through the above arrangement, the visible light stick and the endotracheal tube can be inserted into the guide cavity through the insertion hole. The insertion hole extends in a horizontal direction perpendicular to the guide cavity so that the insertion hole extends along the patient's oral cleft to enlarge the insertion hole, making it easier for doctors to quickly insert the visible light stick and the endotracheal tube into the guide cavity.

[0026] As a further improvement of the above technical solution, the baffle is provided with connecting holes at two opposite ends along the extension direction of the insertion hole, and the two connecting holes are connected with elastic bands through ropes.

[0027] Through the above arrangement, the baffle is connected to an elastic band through the connecting hole, and the elastic band is wrapped around the patient's head and neck to ensure that the visible light stick insertion tooth pad is stably inserted into the patient to prevent the visible light stick insertion tooth pad from falling out.

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] Reference Figures 1 to 4 , several embodiments of the visible light stick intubation tooth pad of the utility model are given below.

[0046] like Figures 1 to 4As shown, the visible light stick intubation tooth pad 100 of the embodiment of the utility model includes a tooth pad component and a tongue depressor component 300 which are connected to each other.

[0047] It can be understood that the tooth pad assembly is provided with a bite portion 200, such as Figures 2 to 4 As shown, the patient's teeth bite the occlusal part 200 and keep the mouth open. The occlusal part 200 is hollow and has a guide cavity 210 to guide the visible light rod to be inserted into the cavity of the hole 610 from the outside to the inside. Figure 1 , Figure 2 and Figure 4 shown.

[0048] It is understandable that the tongue depressor assembly 300 is provided with a guide groove 310 opening upwards, such as Figures 2 to 4 As shown. Since the tooth pad assembly and the tongue depressor assembly 300 are connected, the guide groove 310 receives and conducts the guide cavity 210, so that the inserted visible light rod enters the guide groove 310 from the guide cavity 210. The tongue depressor assembly 300 extends downward in an arc in a direction away from the occlusal portion 200, and the arc curve of the tongue depressor assembly 300 matches the arc curve of the human throat, so that when the patient bites the occlusal portion 200, the tongue depressor assembly 300 is inserted in front of the patient's epiglottis, so that the visible light rod directly enters in front of the epiglottis along the guide cavity 210 and the guide groove 310, helping the doctor to quickly find the epiglottis and quickly perform intubation, and preventing the visible light rod from contacting the tongue and getting stained with saliva, resulting in the lens of the visible light rod being contaminated, and the doctor cannot see the patient's throat clearly.

[0049] It is understandable that the tongue depressor assembly 300 can also depress the tongue to prevent it from falling back, thus avoiding the situation in which anesthetized patients or comatose patients fall into the posterior pharyngeal wall due to relaxation of the floor of the mouth and pharyngeal muscles that support the tongue to maintain a patent upper airway, thereby causing upper airway obstruction.

[0050] In this embodiment, the rear end of the tooth pad assembly and the front end of the tongue depressor assembly 300 are connected, that is, the rear end of the occlusal portion 200 and the front end of the tongue depressor assembly 300 are connected, the rear end of the guide cavity 210 and the front end of the guide groove 310 are connected, the guide groove 310 bends and extends backward and downward, and the visible light stick is inserted into the visible light stick insertion tube tooth pad 100 from front to back.

[0051] It can be understood that the guide cavity 210 is funnel-shaped and gradually decreases toward the tongue depressor assembly 300. Figure 2 and Figure 4As shown, the guide cavity 210 is a cavity with a large front end and a small rear end. The front end opening of the guide cavity 210 is large and connected to the front end surface of the bite portion 200, which facilitates the rapid insertion of the visible light stick into the guide cavity 210. The rear end opening of the guide cavity 210 is small and connected to the rear end surface of the bite portion 200, which facilitates the precise limitation of the position of the visible light stick extending out of the guide cavity 210, ensuring that the visible light stick can be accurately received by the guide groove 310, and avoiding the visible light stick from being offset during the insertion process.

[0052] In some embodiments, the bite portion 200 may be a rectangular parallelepiped extending forward and backward, and the funnel-shaped guide cavity 210 is located at the center of the bite portion 200, so that the visible light stick and the cannula can be accurately inserted from the center of the patient's throat. Specifically, the upper end surface of the bite portion 200 is respectively rounded with the left end surface and the right end surface, and the lower end surface of the bite portion 200 is respectively rounded with the left end surface and the right end surface, so that the patient can bite the bite portion 200 more comfortably and avoid the edges and corners of the rectangular bite portion 200 from blocking the patient's oral cavity.

[0053] In this embodiment, the engaging portion 200 extends forward and backward and corresponds to the guide cavity 210, which is a funnel-shaped structure with a large front end and a small rear end. Figure 2 and Figure 4 As shown, the material of the occlusal portion 200 is saved, and the manufacturing cost of the visible light stick intubation tooth pad 100 is reduced.

[0054] It is understandable that the guide cavity 210 is provided with a limiting hole 400 for communicating with the guide groove 310. Figures 2 to 4 As shown, the rear end opening of the guiding cavity 210 is a limiting hole 400 , and the visible light rod leaves the guiding cavity 210 from the limiting hole 400 and enters the guiding groove 310 .

[0055] It can be understood that the limiting hole 400 is located in the middle of one end of the occlusal portion 200 connected to the tongue depressor assembly 300, that is, the limiting hole 400 is arranged in the middle of the rear end surface of the occlusal portion 200, so that the visible light rod can be accurately inserted from the midline of the patient's oropharynx through the guide cavity 210.

[0056] Furthermore, in terms of projection in the front-to-back direction, the limiting hole 400 is located at the center of the guide cavity 210 .

[0057] In some embodiments, the front end opening of the guide cavity 210 gradually shrinks in both the vertical and horizontal directions toward the limiting hole 400 to limit the insertion position of the visible light stick from both the vertical and horizontal directions to prevent the visible light stick from being offset.

[0058] In this embodiment, the front opening of the guide cavity 210 gradually narrows leftward and rightward toward the limiting hole 400. Since most visible light sticks have a lens at one end that is bent up and down, it is only necessary to prevent the visible light stick from shifting leftward and rightward, so that the structure of the bite portion 200 and the internal guide cavity 210 is simple and easy to manufacture.

[0059] It is understandable that the aperture of the limiting hole 400 corresponds to the diameter of the endotracheal tube used for anesthesia. Specifically, the type of endotracheal tube depends on the inner diameter of the trachea, and the endotracheal tube with an inner diameter of 7.0 mm, 7.5 mm or 8.0 mm is suitable for most adults.

[0060] In this embodiment, the aperture of the limiting hole 400 can accommodate an endotracheal tube with an inner diameter of 8.0 mm. The outer diameter of an endotracheal tube with a standard inner diameter of 8.0 mm is greater than 10.5 mm. Correspondingly, the limiting hole 400 is a round hole with an aperture of 11 mm, so that endotracheal tubes of various specifications can extend from the limiting hole 400 into the guide groove 310, thereby improving the applicability of the visible light stick intubation tooth pad 100.

[0061] It can be understood that the guide groove 310 is a semicircular groove. Figure 2 As shown, when the guide groove 310 receives the guide cavity 210, the semicircular guide groove 310 can semi-enclose the lower end of the limiting hole 400, so that the visible light rod inserted into the endotracheal tube can continue to bend and insert into the patient's oropharynx along the semi-enclosed guide groove 310 to avoid left and right deviation.

[0062] In some embodiments, since the aperture of the limiting hole 400 is 11 mm, the inner diameter of the semicircular guide groove 310 is correspondingly 11 mm, so that the guide cavity 210 and the guide groove 310 are directly connected, making the connection between the tooth pad assembly and the tongue depressor assembly 300 easier and more stable.

[0063] In this embodiment, the inner diameter of the semicircular guide groove 310 is 12 mm, so that the guide groove 310 is slightly larger than the limiting hole 400, so that when the visible light rod extends from the limiting hole 400 and continues to be inserted along the guide groove 310, the contact area between the tracheal tube and the guide groove 310 is reduced, thereby reducing the sliding friction between the two.

[0064] It can be understood that the tongue depressor assembly 300 is flat. Figure 1 and Figure 2 As shown, the contact area between the tongue depressor assembly 300 and the tongue is increased to better depress the tongue and prevent the tongue from falling back. The guide groove 310 is provided at the middle of the upper end of the tongue depressor assembly 300 so that the visible light stick can be inserted accurately into the midline of the patient's oropharynx when it is bent and inserted along the guide groove 310.

[0065] It can be understood that the arc extension length of the tongue depressor assembly 300 is between 6 cm and 8 cm, so that the length of the tongue depressor assembly 300 is sufficient to allow one end of the tongue depressor assembly 300 away from the dental pad assembly to be inserted in front of the patient's epiglottis, ensuring that the visible light rod can be inserted in front of the patient's epiglottis along the guide cavity 210 and the guide groove 310.

[0066] It can be understood that the tooth pad assembly is provided with a baffle 600, and the end of the occlusal portion 200 away from the tongue depressor assembly 300 is connected to the baffle 600. Figures 1 to 4 When the visible light stick intubation tooth pad 100 is inserted, the side of the baffle 600 close to the occlusal portion 200 abuts against the patient's lips, that is, the rear end surface of the baffle 600 abuts against the patient's lips, so as to limit the insertion depth and insertion range of the visible light stick intubation tooth pad 100, and prevent the visible light stick intubation tooth pad 100 from being inserted too deeply into the patient's throat, causing discomfort to the patient's throat.

[0067] It can be understood that the left and right ends of the baffle 600 are bent backwards so that the shape of the baffle 600 can better fit the patient's lips, making the contact area between the baffle 600 and the patient's lips larger and better limiting the insertion position of the bite portion 200 and the tongue depressor assembly 300.

[0068] It is understood that the guide cavity 210 is provided with an insertion hole 610 for penetrating the baffle 600, such as Figure 1 , Figure 3 and Figure 4 As shown, the front end opening of the guide cavity 210 is an insertion hole 610, and the insertion hole 610 penetrates the front end surface and the rear end surface of the baffle 600 along the front-to-back direction. The visible light rod enters the guide cavity 210 through the insertion hole 610 from front to back.

[0069] It can be understood that the insertion hole 610 extends in a horizontal direction perpendicular to the guide cavity 210, that is, the insertion hole 610 extends in a left-right direction. Figure 1 As shown, the insertion hole 610 is extended along the direction of the patient's oral fissure to enlarge the insertion hole 610, thereby facilitating the insertion of the visible light rod.

[0070] It can be understood that, viewed from the projection in the front-to-back direction, the limiting hole 400 is located at the center of the insertion hole 610 .

[0071] It can be understood that the baffle 600 has connecting holes 500 at both ends along the extending direction of the insertion hole 610, that is, the left end and the right end of the baffle 600 each have a connecting hole 500, and the two connecting holes 500 are connected with elastic bands 510 through ropes, such as Figure 1 and Figure 2When the visible light stick intubation tooth pad 100 is used, the elastic band 510 is sleeved on the patient's head and neck, and the tightness is adjusted to further firmly connect the visible light stick intubation tooth pad 100 to the patient to prevent the patient's teeth from loosening and causing the visible light stick intubation tooth pad 100 to fall off.

[0072] In this embodiment, the dental pad assembly and the tongue depressor assembly 300 are integrally formed so that the dental pad assembly and the tongue depressor assembly 300 are structurally coherent. The visible light stick cannulated dental pad 100 is a disposable plastic product, which makes the visible light stick cannulated dental pad 100 have the advantages of low cost and strong installation, and is very suitable for the manufacture and production of the visible light stick cannulated dental pad 100.

[0073] The preferred implementation methods of the utility model are described in detail above, but the invention of the utility model is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the utility model. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
