Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to an oral secretion clearing device. Background Art

[0002] In the modern medical field, bronchoscopy is an important means of diagnosis and treatment of respiratory diseases, and its safety and efficiency have always been the focus of clinicians. However, during bronchoscopy, a large amount of secretions are often produced in the patient's mouth. These secretions not only affect the doctor's visual clarity, but also may increase the difficulty of operation and the patient's discomfort, and even cause risks such as aspiration. Traditional secretion removal methods often rely on manual operations by medical staff, such as using a suction device with a tongue depressor and other tools, but this method has problems such as inconvenient operation, limited field of view, low removal efficiency, and possible increase in patient pain.

[0003] With the continuous advancement of medical technology and the improvement of patients' requirements for the quality of medical services, it is particularly important to develop an integrated, efficient and comfortable oral secretion removal device.

[0004] The disclosure (announcement) number is (CN 117796941 A), which is a saliva drainage mechanism and cleaning device for clinical examination in the oral department, belonging to the technical field of oral medical devices. It includes a mask assembly, a moving cylinder assembly, a cardboard component, a saliva suction assembly, a negative pressure drive rod assembly, a negative pressure locking component and a cleaning component. The whole is worn on the patient's face through the mask assembly. After the negative pressure pump generates negative pressure, the moving cylinder can be driven by the transmission mechanism in the negative pressure drive rod assembly to move inward, so that the symmetrically distributed cardboards can form an opening action to open the patient's mouth; and synchronously, the saliva suction head can be extended into the patient's mouth, and the negative pressure pump can form a negative pressure adsorption force on the saliva suction head, so that the saliva and other secretions in the mouth are sucked and collected into the re-suction bucket; and through the combined action of the negative pressure locking component, the guide rod can form a stable and safe support for the moving adjustment position of the moving cylinder, and the cleaning seat can be opened with the opening of the cardboard to fully disinfect and clean the oral cavity.

[0005] However, the position of the saliva suction head in the oral cavity cannot be adjusted, making it impossible to fully remove the secretions in the oral cavity; and when the secretions are removed, the tongue may move around, interfering with the removal of the secretions and affecting the efficiency of removing the oral secretions.

[0037] For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] During the bronchoscopy operation, a large amount of secretions are often produced in the patient's mouth, which not only affects the doctor's visual clarity, but also may increase the difficulty of operation and the patient's discomfort, and even cause risks such as aspiration. Traditional secretion removal methods often rely on manual operations by medical staff, such as using a suction device with tools such as a tongue depressor, but this method has problems such as inconvenient operation, limited visual field, low removal efficiency, and possible increase in patient pain.

[0039] In order to solve the above problems, the present application discloses an oral secretion removal device. Figure 1-Figure 11The device specifically includes a mouthpiece, which includes an upper alveolar socket 1 and a lower alveolar socket 2, and also includes a cleaning device arranged between the upper alveolar socket 1 and the lower alveolar socket 2. The cleaning device includes a sliding support structure arranged between the upper alveolar socket 1 and the lower alveolar socket 2, a suction structure inserted in the support structure, a movable tongue depressor structure connected to one end of the suction structure, and a collection structure connected to the other end of the suction structure.

[0040] The two ends of the upper alveolar socket 1 and the lower alveolar socket 2 are fixedly connected, and both the upper alveolar socket 1 and the lower alveolar socket 2 are made of medical silicone, and a lace 7 is hinged at the connection between the upper alveolar socket 1 and the lower alveolar socket 2, which is used to hang on the neck and fix the upper alveolar socket 1 and the lower alveolar socket 2. When in use, first hang the lace 7 on the patient's neck, then place the upper teeth in the upper alveolar socket 1, and the lower teeth in the lower alveolar socket 2 and fix them.

[0041] In order to better remove oral secretions, the present application is also provided with a sliding support structure for slidingly supporting the suction tube 5, so that the suction tube 5 can slide between the upper alveolar 1 and the lower alveolar 2, and can attract oral secretions in a wider range. Specifically, the sliding support structure includes a fixing seat arranged between the upper alveolar 1 and the lower alveolar 2 and matching the inner circumference of the upper alveolar 1 and the lower alveolar 2. The fixing seat includes an upper top plate 3 arranged below the upper alveolar and a lower top plate 4 located above the lower alveolar. Both the upper top plate 3 and the lower top plate 4 are made of medical silicone. A groove 10 is provided on the opposite side of the upper top plate 3 and the lower top plate 4. A sliding block 13 is provided in the groove 10, and a suction structure is provided inside the sliding block 13.

[0042] The upper part of the sliding block 13 is sleeved in the slot 10 of the upper top plate 3, and the lower part is sleeved in the slot 10 of the lower top plate 4. The suction structure includes a suction tube 5 inserted in the sliding block 13, and an elastic component located between the suction tube 5 and the sliding block 13 for controlling the displacement of the suction tube 5. The movement of the suction tube 5 is manually controlled by medical staff, so that the movement of the suction tube 5 drives the sliding block 13 to move in the slot 10.

[0043] It should be noted that the suction tube 5 is a medical device used to absorb secretions, blood and other substances in the human body to maintain the patency of the respiratory tract and the patient's respiratory function. The suction tube is made of medical soft plastic and can be selected in appropriate size and length according to different use occasions and needs.

[0044] Specifically, the suction tube 5 includes a suction head located at one end of the suction tube, facing the tongue side, and the suction head is usually conical, which can better absorb and absorb body fluids. The other end of the suction tube 5 is connected to a collection structure located outside the oral cavity, and the collection structure includes a collection bucket 8 connected to the other end of the suction tube 5, and a negative pressure pump 9 electrically connected to the collection bucket 8. The negative pressure pump 9 generates negative pressure to absorb secretions in the oral cavity or respiratory tract, which is simple to operate and highly efficient. In addition, a suction tube valve is also provided inside the suction tube 5 to prevent the body fluid in the suction tube 5 from flowing back, so as to keep the tube clean.

[0045] The elastic component includes a fixing member sleeved on the suction tube 5, a spring 18 located below the fixing member, one end of the spring 18 is connected to the fixing member, and the other end is connected to the inside of the sliding block. It should be noted that the outer diameter of the suction tube 5 is smaller than the space inside the sliding block 13, so that the suction tube 5 can be adjusted in the up, down, left and right directions inside the sliding block 13. By manually pressing the suction tube 5 located outside the oral cavity, the suction head inside the oral cavity can be displaced up and down by the force generated by pressing, which is convenient for suction of oral secretions in different parts. After the pressing force is canceled, the suction tube 5 can be restored to its original position by the elastic force of the spring 18, which is convenient to use.

[0046] When the suction tube 5 is suctioning, the tongue needs to be limited in order to better suction the oral secretions. Therefore, the present application also has a movable tongue depressor structure, which can not only depress different parts of the tongue, but also control the tip of the tongue to prevent the tip of the tongue from moving around. Specifically, the movable tongue depressor structure includes a tongue depressor 12 connected to one end of the suction tube, and a movable adjustment component connected to the tongue depressor 12 for adjusting the position of the tongue depressor.

[0047] The movable adjustment assembly includes a movable sleeve 6 sleeved in the lower top plate 4, and the movable sleeve 6 is located below the inner end of the lower top plate 4 and is connected to a movable part, and the movable part is connected to a tongue depressor 12. It should be noted that the movable sleeve 6 can also be used as a bronchoscope operation port, and the bronchoscope is inserted into the oral cavity through the movable sleeve 6.

[0048] It should be noted that the bronchoscope is suitable for observation of lesions in lobes, segments and subsegments of the bronchi, biopsy sampling, bacteriology and cytology examinations, and can be used with a TV system for photography, teaching and dynamic recording. The bronchoscope is equipped with a biopsy sampling structure, which can help discover early lesions and can carry out internal surgical operations such as polypectomy. It is a good precision instrument for bronchial and lung disease research and postoperative examinations. When in use, the doctor will insert the bronchoscope through the movable sleeve 6 into the patient's mouth, and guide the bronchoscope downward into the trachea through the throat for subsequent observation, sampling, treatment and other operations.

[0049] Specifically, a hole is provided in the lower top plate 4, and a movable sleeve 6 matching the inner diameter thereof is sleeved in the hole. In the absence of external interference, the movable sleeve 6 and the hole remain relatively still. In the case of external force pushing and pulling the movable sleeve 6, the movable sleeve 6 can be displaced in the hole. When the movable sleeve 6 is displaced, the movable part connected to the movable sleeve 6 will also be displaced, and then the tongue depressor 12 connected to the movable part will also be displaced inside the oral cavity. Since the movable part includes a connecting block fixedly connected to the movable sleeve 6 and a movable ring 17 movably connected to the connecting block, and the outer wall of the movable ring 17 is fixedly connected to the tongue depressor 12, the tongue depressor 12 can be moved on the tongue inside the oral cavity through the movable ring 17, which is convenient for pressing different parts of the tongue, and then it is convenient for the suction tube 5 to attract secretions from different parts of the tongue.

[0050] A tongue tip placement frame 15 is also fixedly connected to the bottom of the tongue depressor 12 for placing the tongue tip therein so that the tongue tip will not move around under the tongue depressor 12. A plurality of small suction cups 11 are also provided at the bottom of the tongue depressor 12 to suck the tongue, so that the tongue depressor 12 has a better effect of suppressing the tongue and is easy to operate.

[0051] When in use, first guide the patient to put the tip of the tongue into the tongue tip placement frame 15, then use the tongue depressor 12 to press the tongue, and then use the small suction cup 11 to suck the tongue to prevent the tongue from moving. After pressing, the medical staff manually controls the suction tube 5 to rotate in the up, down, left and right directions inside the oral cavity, so that the suction tube 5 can suck the oral secretions around the pressed part. When the position of the tongue depressor 12 inside the oral cavity needs to be changed, the medical staff manually controls the sliding block 13 outside the oral cavity to move, so that the suction tube 5 inside the oral cavity moves accordingly, and then the tongue depressor 12 is driven to move inside the oral cavity through the connecting tube of the suction tube 5, thereby achieving the purpose of changing the position of the tongue depressor 12 inside the oral cavity.

[0052] Preferably, since the length of the suction tube 5 inside the oral cavity is fixed, in order to coordinate the tongue depressor to move forward or backward under the guidance of the movable sleeve 6, the present application also provides a slide groove 16 with the same length as the movable sleeve 6 on the tongue depressor 12 for adjusting the distance of the suction tube 5 on the tongue depressor 12. The slide groove 16 is specifically provided at the connection between the tongue depressor and the suction tube 5. The tongue depressor 12 and the suction tube 5 are connected through a connecting tube 14. One end of the connecting tube 14 is sleeved on the outer wall of the suction tube 5, and the other end is clamped in the slide groove 16. When the movable sleeve 6 is displaced, the tongue depressor 12 is also displaced, so that the connecting tube 14 moves a corresponding distance in the slide groove 16 provided on the tongue depressor 12, while the distance of the suction tube 5 inside the oral cavity remains relatively unchanged.

[0053] When in use, the tongue depressor 12 is used to more deeply press the tongue, and the movable sleeve 6 can be pushed to move the movable sleeve 6 toward the inside of the oral cavity, thereby causing the movable sleeve 6 to drive the tongue depressor 12 connected thereto to move a corresponding distance. Example 1

[0054] During the bronchoscope operation, a large amount of secretions are often produced in the patient's mouth. These secretions not only affect the doctor's visual clarity, but also may increase the difficulty of operation and the patient's discomfort, and even cause risks such as aspiration. Therefore, the use of the oral secretion removal device of the present application can effectively solve the above problems. When using it, first put the lace hanger on the patient's neck, and then let the patient place the upper teeth in the upper alveolar 1 and the lower teeth in the lower alveolar 2 and fix them. Then the medical staff will insert the bronchoscope into the patient's mouth through the movable sleeve according to the operating specifications, and then perform a bronchoscope examination. During the bronchoscope examination, the patient's oral secretions need to be cleared in time. Therefore, the oral secretion removal device of the present application is used for cleaning. When using it, first guide the patient to put the tip of the tongue into the tongue tip placement frame 15, and then use the tongue depressor 12 to suppress it. The tongue is sucked by a small suction cup 11 to prevent the tongue from moving. After the pressing is done, the medical staff manually controls the suction tube 5 to rotate in the up, down, left and right directions inside the oral cavity, so that the suction tube 5 can suck the oral secretions around the pressing part. When the position of the tongue depressor 12 inside the oral cavity needs to be changed, the medical staff manually controls the sliding block 13 outside the oral cavity to move, so that the suction tube 5 inside the oral cavity moves accordingly, and then the tongue depressor 12 is driven to move inside the oral cavity through the connecting tube of the suction tube 5, thereby achieving the purpose of changing the position of the tongue depressor 12 inside the oral cavity. Example 2

[0055] The use process and method of this embodiment are the same as those of Embodiment 1, with the only difference being that in this embodiment, by manually pressing the suction tube 5 located outside the oral cavity, the suction head inside the oral cavity can be displaced up and down by the force generated by the pressing, thereby facilitating the suction of oral secretions from different parts. After the pressing force is cancelled, the suction tube 5 can be restored to its original position by the elastic force of the spring 18. Example 3

[0056] The use process and method of this embodiment are the same as those of Embodiment 1. The only difference is that in this embodiment, the tongue can be pressed more deeply and comprehensively by moving the tongue depressor 12. When it is necessary to change the position of the tongue depressor 12 so that the tongue depressor 12 can press other parts of the tongue, the movable sleeve 6 can be pushed to move the movable sleeve 6 toward the inside of the oral cavity, thereby causing the movable sleeve 6 to drive the tongue depressor 12 connected thereto to move a corresponding distance.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
