Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to a weighted, sustainable suction dental pad. Background Technology
[0002] In clinical medicine, airway management has always been a challenging and crucial issue in intensive care units (ICUs), and a hot topic of research and discussion among scholars both domestically and internationally. Prospective studies on the major complications of airway management in ICUs have been conducted both domestically and internationally, and the data indicate that the quality of airway management is not satisfactory, including the oral hygiene care of critically ill patients.
[0003] Patients with endotracheal intubation are unable to eat orally, have limited swallowing function, and experience a decline in the oral cavity's self-cleaning ability, leading to the accumulation of secretions and increased bacterial colonization, which in turn causes oral infections and bad breath. More seriously, the epiglottis may not close completely during intubation, allowing oral secretions to easily descend into the airway and induce ventilator-associated pneumonia.
[0004] Currently, there is no dedicated equipment for intraoral suction in clinical practice. In clinical practice, the suction catheter is often fixed to the bite block for continuous suction, which can easily irritate the oral mucosa and pharynx, and may cause nausea, vomiting, oral mucosal damage, pain, or even infection.
[0005] Theoretically speaking, oral secretions are secreted constantly, and the location where oral secretions accumulate changes with body position, leading to poor suction accuracy.
[0006] Therefore, it is essential to improve the aspiration efficiency of oral secretions in patients. Utility Model Content

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution. Example 1
[0031] like Figures 1 to 2 The embodiment of this application shows a sustainable suction mouthguard with counterweight, comprising: a cylindrical mouthguard body 1 and a suction tube 2 with a counterweight 3 at one end; the mouthguard body 1 has a hollow first channel 11, the diameter of the first channel 11 being larger than the diameter of the suction tube 2; the suction tube 2 passes through the first channel 11 and is detachably fixed to the mouthguard body 1; the counterweight 3 has a second channel 31 passing through the counterweight 3; one end of the second channel 31 is connected to the suction tube 2, and the other end of the second channel 31 is connected to the outside atmosphere.
[0032] Preferably, in the embodiments provided in this application, the dental pad body 1 is made of dental pads commonly used in hospitals. The outer shell of the dental pad body 1 is provided with an occlusal wing 13. The dental pad body 1 is provided with a hollow first channel 11. The suction tube 2 is a flexible tube made of medical silicone. The length of the suction tube 2 is between 4 and 8 centimeters, and the length of the suction tube 2 must be greater than the length of the dental pad body 1. The suction tube 2 is set inside the first channel 11, and both ends of the suction tube 2 are located outside the first channel 11.
[0033] The counterweight 3 is made of a solid material with a certain weight, such as "medical stainless steel, medical silicone". The counterweight 3 is cylindrical in shape. A second channel 31 is provided through the axis of the counterweight 3. A protective shell 4 is provided on one end of the suction tube 2. The protective shell 4 is made of the same material as the suction tube 2. The counterweight 3 is wrapped by the protective shell 4 and fixed to one end of the suction tube 2. One end of the second channel 31 is connected to the suction tube 2, and the other end is connected to the outside atmosphere through the first opening 422.
[0034] The protective shell 4 is composed of a first shell 41 and a second shell 42. The first shell 41 is integrally formed with the suction tube 2. The first opening 422 is provided on the second shell 42. Both the first shell 41 and the second shell 42 are provided with openings suitable for the installation of the counterweight 3. The first protrusion 421 is circumferentially arranged around the opening of the second shell 42 on the outer surface of the second shell 42. The first groove 411 is circumferentially arranged around the opening of the first shell 41 on the inner surface of the first shell 41. During installation, the second shell 42 is fitted onto the counterweight 3, and the opening of the second channel 31 is aligned with the first opening 422. Then, the other part of the counterweight 3 is embedded into the first shell 41, and the installation of the counterweight 3 is completed by the cooperation of the first protrusion 421 and the first groove 411.
[0035] The suction tube 2, without the counterweight 3, has a pluggable adapter 21 at one end. The adapter 21 is a clinically common type. One end of the adapter 21 is inserted into the suction tube 2 for fixation, and the other end connects to the negative pressure suction device. A relatively convex disc structure is located in the middle of the adapter 21, and a first connector 211 is located on this disc structure. The first connector 211 is a flat silicone soft body with an embedded first strong magnet 51. A second connector is located on the shell at one end of the dental pad body 1. 12. The second connector 12 is a flat plastic structure with a second strong magnet 52 embedded in it. The first connector 211 and the second connector 12 are magnetically connected by the first strong magnet 51 and the second strong magnet 52. During installation, after the counterweight 3 is installed in the protective shell 4, the end of the suction tube 2 without the counterweight 3 is passed through the first channel 11 and the adapter 21 is inserted into the suction tube 2. The suction tube 2 is fixed to the dental pad body 1 by the magnetic connection between the strong magnets on the first connector 211 and the second connector 12.
[0036] During the use of the mouthguard, when the patient changes position, oral secretions will accumulate at the lowest point of gravity. At this time, the counterweight 3 on the suction tube 2 will also be at the lowest point of gravity under the action of gravity, so that the accumulated oral secretions can be accurately and effectively suctioned.
[0037] In this embodiment, by setting a counterweight on the suction tube 2, the suction port of the suction tube 2 is always located where the patient's oral secretions accumulate, thus improving the accuracy of suctioning oral secretions. Example 2
[0038] More preferably, based on the above embodiments, such as Figure 3 The difference is that the first connector 211 on the adapter 21 is a plug that protrudes and extends relative to the disc structure, while the second connector 12 on the dental pad body 1 is a slot suitable for plug insertion.
[0039] It should be noted that the order of the embodiments described above is merely for descriptive purposes and does not represent the superiority or inferiority of the embodiments. Furthermore, specific embodiments have been described above. Other embodiments are within the scope of the appended claims.
