Description

Technical Field

[0001] The invention relates to the field of respiratory medicine, in particular to a tongue-depressing multi-purpose intracavity lighting mouth opener for aerosol drug delivery in the oral and nasal cavities and upper respiratory tract. Background Art

[0002] A mouth opener is an essential medical device for transesophageal or transtracheal surgery.

[0003] In the clinical practice of respiratory medicine, mouth openers are used in large quantities. At the same time, another way to treat the upper respiratory tract, including the nasal cavity, upper bronchi and throat, is nebulization. The specific principle is that the atomized drug is directly absorbed by the human body.

[0004] Currently, most nebulization methods involve having the patient directly hold an nebulizer nozzle in their mouth and then undergoing nebulization treatment.

[0005] In practice, the mouth opener has the following technical problems:

[0006] Nebulizers act directly on the oral cavity, so only a small amount of the drug will enter the lungs, and most of it will enter the esophagus;

[0007] Current atomizer nozzles do not take into account that people actually breathe. Specifically, when people exhale, the medicine is still coming out, so a lot of medicine is blown out again.

[0008] The mouth gag does not have the function of pumping oxygen. Many people who need surgery need oxygen supply, so the oxygen tube needs to be re-taped on the patient to fix it; the current mouth gag does not have a fixing function;

[0009] Current mouth openers do not have the function of fixing the tongue. Patients may bite their tongues randomly under anesthesia, but tongue movements can pose risks to ongoing transesophageal or transtracheal procedures.

[0010] Once something is put into a person's mouth, the mouth will secrete saliva. After the mouth opener is placed, the saliva secreted by the person will be concentrated in the throat. The patient will be unable to stand up and swallow unconsciously, which may cause the risk of choking.

[0011] Current mouth openers cannot directly deliver drugs to the nasal and oral cavities simultaneously; nor can they cleverly utilize human breathing to fully utilize drugs for simultaneous delivery.

[0012] Currently, oral lighting is provided by doctors wearing a lamp on their heads. However, doctors sometimes hold a large number of instruments in their hands, which may be blocked in the narrow oral space, posing a certain risk of blind spots.

[0019] Purpose of the invention: To provide a tongue-depressing multi-purpose intracavitary lighting opener for aerosol drug delivery in the oral and nasal cavities and upper respiratory tract with better effect. The specific purpose can be seen in the multiple substantial technical effects in the specific implementation part.

[0020] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0021] The multi-purpose tongue-pressing intracavity lighting mouth opener for oral, nasal and upper respiratory tract aerosol drug delivery is characterized by:

[0022] The mouth opener comprises a mouth opener body 2, which comprises a bite portion 3, which is a protruding structure. A tongue depressor plate 4 is arranged in the middle of the protruding structure. The tongue depressor plate 4 divides the interior of the bite portion 3 into two parts, the lower part being a tongue space 6 and the upper part being an operating space.

[0023] The bite part 3 is made of medical grade plastic;

[0024] A waterproof tracheal oral lamp 5 is arranged on the tongue depressor soft plate 4, and the tracheal oral lamp 5 is integrally fixed with screws or glued to the tongue depressor soft plate 4;

[0025] A switch 8 is arranged on one side of the tongue depressor soft plate 4;

[0026] The tongue depressor 4 is a medical grade latex layer or rubber layer;

[0027] An oblique nostril guide tube 1 is also arranged on the opener body 2, and an oxygen tube can be inserted into the oblique nostril guide tube 1 and guided to the nose;

[0028] A clamping ring 13 is arranged on the tongue depressor 4 , and a saliva suction tube 14 is clamped on the clamping ring 13 .

[0029] A further technical solution of the present invention is that it also includes a one-way valve atomizer connecting port tube 11, which is connected to the bite part 3, and a one-way valve is arranged in the one-way valve atomizer connecting port tube 11, and the atomizer pipeline can be connected to the one-way valve atomizer connecting port tube 11.

[0030] A further technical solution of the present invention is that a nasal medication tube 10 is arranged upward on the occlusal portion 3, and the nasal medication tube 10 leads to the inclined oxygen tube 9; the nasal medication tube 10 can be used to divert medicine from the oral cavity to the nasal cavity.

[0031] A further technical solution of the present invention is that the clamping ring 13 is an elastic clamping structure, and the saliva suction tube 14 clamped by it is connected to an intermittent suction pump and a container.

[0032] A further technical solution of the present invention is that the oblique nostril guide tubes 1 include two and the nasal medication tubes 10 also include two.

[0033] A further technical solution of the present invention is that it further comprises a direct connection tube 15 , which directly connects the one-way valve atomizer connecting mouth tube 11 and the nasal medication tube 10 .

[0034] A further technical solution of the present invention is that the four walls of the bite part 3 are made of hard plastic, and the four walls are connected as a whole by a connecting corner 12; the connecting corner 12 is hard or soft, and when it is soft, the size of the bite part 3 can be fine-tuned according to the size of the tongue.

[0035] A further technical solution of the present invention is that the one-way valve is a medical one-way valve.

[0036] A further technical solution of the present invention is that the nasal medication tube 10 is connected to the inclined oxygen tube 9 and the two are integrated into one pipeline, and the pipeline is connected to a hose that can directly pass into the nostrils. Beneficial effects

[0037] To address the shortcomings of existing technologies, such as the lack of oxygen pumping function in mouth gags, which many patients undergoing surgery require, the oxygen tube must be taped to the patient for securement. Current mouth gags lack a secure fixation function. This patent pioneers the use of mouth gags to assist in securing the oxygen tube during surgery, reducing the clutter of tubing in the surgical area.

[0038] In response to the defects of the existing technology, "the current tongue openers do not have the function of fixing the tongue. The patient may bite randomly under anesthesia, but the movement of the tongue will pose a risk to the ongoing transesophageal or transtracheal operation." This patent pioneered the use of a medical-grade latex or rubber layer of a tongue depressor 4 to cover or relatively limit the tongue, leaving the space above for surgical operations.

[0039] In response to the defect of the existing technology that "once an object is put into the human mouth, the mouth will secrete saliva. After the mouth opener is placed, the saliva secreted by the person will be concentrated in the throat. The patient cannot get up and swallows unconsciously, which may cause the risk of choking." This patent innovatively uses a saliva suction tube 14 to regularly extract various liquids secreted in the patient's mouth due to the placement of the mouth opener, thereby preventing the patient from choking, especially when the patient is unconscious.

[0040] In response to the defects of the existing technology, "Current oral lighting is performed by doctors wearing a lamp on their heads, but sometimes they hold a large number of instruments in their hands, which may be blocked in the narrow oral space, posing a certain risk of blind spots." This patent pioneered the use of a tracheal oral lamp 5 to illuminate the oral cavity directly without any obstruction, so that even various surgical forceps and irrigation tubes will not affect the surgical field.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0053] This patent provides multiple parallel solutions. The differences in descriptions are improvements or parallel solutions based on the basic solution. Each solution has its own unique characteristics. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described in this article can be any fixing method such as threaded fixing, bolt fixing, or gluing.

[0054] This patent has two basic structures as a whole. The first is the basic structure, which is the structure shown in Example 1. The rest are structures in which the mouth opener has an atomizing port for administering medicine to the nasal cavity and mouth at the same time. You can refer to the other embodiments except Example 1.

[0055] Example 1: Combination Figure 1 and Figure 7 A multi-purpose tongue-depressing intracavitary lighting mouth opener for aerosol drug delivery in the oral and nasal cavities and upper respiratory tract, characterized in that:

[0056] The mouth opener comprises a mouth opener body 2, which comprises a bite portion 3, which is a protruding structure. A tongue depressor plate 4 is arranged in the middle of the protruding structure. The tongue depressor plate 4 divides the interior of the bite portion 3 into two parts, the lower part being a tongue space 6 and the upper part being an operating space.

[0057] The bite part 3 is made of medical grade plastic;

[0058] A waterproof tracheal oral lamp 5 is arranged on the tongue depressor soft plate 4, and the tracheal oral lamp 5 is integrally fixed with screws or glued to the tongue depressor soft plate 4;

[0059] A switch 8 is arranged on one side of the tongue depressor soft plate 4;

[0060] The tongue depressor 4 is a medical grade latex layer or rubber layer;

[0061] An oblique nostril guide tube 1 is also arranged on the opener body 2, and an oxygen tube can be inserted into the oblique nostril guide tube 1 and guided to the nose;

[0062] A clamping ring 13 is arranged on the tongue depressor 4 , and a saliva suction tube 14 is clamped on the clamping ring 13 .

[0063] The substantial technical effects and implementation process of this technical solution, i.e., the basic functions, are as follows:

[0064] To address the shortcomings of existing technologies, such as the lack of oxygen pumping function in mouth gags, which many patients undergoing surgery require, the oxygen tube must be taped to the patient for securement. Current mouth gags lack a secure fixation function. This patent pioneers the use of mouth gags to assist in securing the oxygen tube during surgery, reducing the clutter of tubing in the surgical area.

[0065] In response to the defects of the existing technology, "the current tongue openers do not have the function of fixing the tongue. The patient may bite randomly under anesthesia, but the movement of the tongue will pose a risk to the ongoing transesophageal or transtracheal operation." This patent pioneered the use of a medical-grade latex or rubber layer of a tongue depressor 4 to cover or relatively limit the tongue, leaving the space above for surgical operations.

[0066] In response to the defect of the existing technology that "once an object is put into the human mouth, the mouth will secrete saliva. After the mouth opener is placed, the saliva secreted by the person will be concentrated in the throat. The patient cannot get up and swallows unconsciously, which may cause the risk of choking." This patent innovatively uses a saliva suction tube 14 to regularly extract various liquids secreted in the patient's mouth due to the placement of the mouth opener, thereby preventing the patient from choking, especially when the patient is unconscious.

[0067] In response to the defects of the existing technology, "Current oral lighting is performed by doctors wearing a lamp on their heads, but sometimes they hold a large number of instruments in their hands, which may be blocked in the narrow oral space, posing a certain risk of blind spots." This patent pioneered the use of a tracheal oral lamp 5 to illuminate the oral cavity directly without any obstruction, so that even various surgical forceps and irrigation tubes will not affect the surgical field.

[0068] Embodiment 2: As a further improved solution, a parallel solution, or an optional independent solution, this embodiment further includes a one-way valve atomizer connecting port tube 11, which is connected to the bite portion 3 and has a one-way valve disposed therein. The atomizer pipe can be connected to the one-way valve atomizer connecting port tube 11. The substantial technical effect of this technical solution and its implementation process are as follows: a groundbreaking atomizing nozzle with an opening function is provided.

[0069] Example 3: As a further improved solution, a parallel solution, or an optional independent solution, a nasal medication tube 10 is arranged upward on the occlusal portion 3, and the nasal medication tube 10 is connected to the inclined oxygen tube 9. The nasal medication tube 10 can be used to divert medication from the oral cavity to the nasal cavity. The substantial technical effects and implementation process of this technical solution are as follows:

[0070] In response to the defect of the existing technology that "openers act directly on the oral cavity, so only a small part of the medicine will enter the lungs, and most of it will enter the esophagus;" this patent pioneered the transformation of the nebulizer into one that can receive atomized medicine in both the oral cavity and the nasal cavity, solving the problem of the current nebulizer's atomized medicine droplets directly entering the esophagus.

[0071] In response to the shortcomings of existing technologies, "Current atomizer nozzles do not take into account that people actually breathe. Specifically, when people exhale, the medicine continues to be discharged, so a lot of medicine is blown out again." This patent innovatively sets a one-way valve. When people exhale, the exhaled gas will not impact the incoming atomized droplets, causing droplet waste. This patent innovatively allows the oral and nasal cavities to receive medicine at the same time.

[0072] This embodiment also has a significant feature, that is, the mixed supply of oxygen and medicine. This fills the gap in this field, see Figure 3 and Figure 5 .

[0073] Example 4: As a further improved, parallel, or independent solution, the clamping ring 13 is a resilient clamping structure, which holds a saliva suction tube 14 connected to an intermittent suction pump and container. The substantial technical effect of this technical solution and its implementation process are as follows: It pioneers the use of a fixed tube within the mouthpiece to extract saliva and other fluids.

[0074] Example 5: As a further improved solution, a parallel solution, or an optional independent solution, two oblique nostril guide tubes 1 are included; two nasal medication tubes 10 are also included. The substantial technical effect and implementation process of this technical solution are as follows: Alternatively, one tube may be included, i.e., suitable for single-nostril medication and oxygen supply.

[0075] Example 6: As a further improved solution or a parallel solution or an optional independent solution, it also includes a direct connection tube 15, which directly connects the one-way valve nebulizer to the mouth tube 11 and the nasal drug delivery tube 10. The actual technical effect of the technical solution here and its implementation process are as follows: that is, when a person exhales outward from the mouth, the one-way valve blocks the exhaled air and lets it out from the gap between the teeth, without washing away the medicine; at this time, the medicine will be partially gathered near the nasal cavity through the nasal drug delivery tube 10. It is preferred that a one-way valve is also arranged there, or there may be no one-way valve, because the main breathing method is the mouth, and the nose is auxiliary, and the atomized medicine can be directly supplied to the nose at the same time. Since the mouth carries a large amount of atomized medicine, the medicine delivered to the nose is also appropriate, which is better than the existing technology that does not deliver the medicine to the nose at all, and can directly reach the nasal cavity, upper bronchi and lungs of the upper respiratory tract.

[0076] Example 7: As a further improved, parallel, or independent solution, the four walls of the bite portion 3 are made of hard plastic, connected as a whole by connecting corners 12. Connecting corners 12 can be hard or soft. When soft, the size of the bite portion 3 can be finely adjusted to the size of the tongue. The substantial technical effect of this technical solution and its implementation process are as follows: It primarily adapts to the varying sizes and shapes of different tongues.

[0077] Example 8: As a further improved solution, a parallel solution, or an optional independent solution, the one-way valve is a medical one-way valve. A nasal medication tube 10 is connected to an inclined oxygen tube 9, and the two are combined into a single pipeline. This pipeline is connected to a flexible tube that can be directly inserted into the nostrils. The substantial technical effect and implementation process of this technical solution are as follows: The medical one-way valve is readily available technology, and a check valve can be used. Examples include a micro air negative pressure check valve, a micro plastic one-way valve, and a medical stop valve. These are all commonly used medical plastic components.

[0078] It should be noted that the solution in this paragraph is at least a new type of multi-purpose medical device, which is an individual that can be sold independently, and the solutions in the following paragraphs are parallel solutions or improved solutions.

[0079] Innovatively, each of the above effects exists independently, and a set of structures can be used to combine the above results.

[0080] It should be noted that the multiple solutions provided by this patent include the basic solutions themselves, are independent of each other, and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.

[0081] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications are intended to fall within the scope of the claims.
