Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a nasal suction-assisted mirror. Background Art
[0002] In the actual clinical process, many patients with poor sputum drainage need to have sputum suctioned. Clinically, there is already a method of suctioning sputum through a fiberoptic bronchoscope. This method is cumbersome to operate, has a relatively high risk, and there are few doctors who can perform the operation. However, patients may need sputum suction at any time. Comparatively speaking, the method of nasal suction is more convenient and fast. Conventional nasal suction is to insert a sterile sputum suction tube through the nasal cavity to the glottis under aseptic operation, enter the airway through the glottis, and then turn on the negative pressure to aspirate sputum. However, in many patients, the cough reflex is weakened. Nurses rely entirely on experience to insert the sputum suction tube into the airway through the glottis. During intubation, due to the curved intubation path, even if the sputum suction tube is made of flexible material, it is very difficult to easily insert it into the airway, and sometimes it simply cannot enter the airway, resulting in a significant reduction in the sputum suction effect. Content of the Utility Model
[0003] The purpose of the utility model is to provide a nasal suction-assisted mirror, which can be equipped with a camera at the end cap of the insertion tube and cooperate with a display screen, so as to directly observe the glottis, thereby facilitating the operation of inserting the insertion tube into the airway.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0023] Please refer to Figure 1 and Figure 2 , a nasal suction-assisted mirror shown in a preferred embodiment of the present application includes an insertion tube 1, a suction tube 2, an optical fiber 3, and at least two light guide beams 4. An end cap 11 is provided at the end of the insertion tube 1, and a plurality of balls 12 are provided along the circumferential edge of the side of the end cap 11 away from the insertion tube 1. The suction tube 2 is disposed inside the insertion tube 1, and the end of the suction tube 2 passes through the end cap 11 and extends outward. The optical fiber 3 is disposed inside the insertion tube 1, a camera 31 is provided at one end of the optical fiber 3, a display screen is provided at the other end of the optical fiber 3, and the camera 31 passes through the end cap 11 and extends outward. The at least two light guide beams 4 are disposed inside the insertion tube 1, and the ends of the light guide beams 4 pass through the end cap 11 and extend outward.
[0024] In the actual clinical process, many patients with poor expectoration need to have their sputum suctioned. Clinically, there is already a method of suctioning sputum through a fiberoptic bronchoscope. This method is cumbersome to operate, has a relatively high risk, and there are fewer doctors who can perform the operation. However, patients may need sputum suctioning at any time. Comparatively speaking, the method of nasal suction is more convenient and fast. Conventional nasal suction is to insert a sterile suction tube 2 through the nasal cavity to the glottis under aseptic operation, enter the airway through the glottis, and then turn on the negative pressure to aspirate the sputum. However, in many patients, the cough reflex is weakened. Nurses rely entirely on experience to insert the suction tube 2 through the glottis into the airway. However, due to the curved intubation path during intubation, even if the suction tube 2 is made of a flexible tube material, it is very difficult to easily insert it into the airway, and sometimes it simply cannot enter the airway, resulting in a significant reduction in the sputum suction effect.
[0025] Therefore, according to the solution of the embodiment of the present utility model, by arranging the camera 31 at the end cap 11 of the insertion tube 1 in cooperation with the display screen, the glottis can be directly observed, so as to facilitate the operation of inserting the insertion tube 1 into the airway. At the same time, the designed ball 12 on the end cap 11 can guide during the insertion process of the insertion tube 1, making the intubation process more convenient and fast.
[0026] The following will be described in detail with specific embodiments:
[0027] Please refer to Figure 2 , an arc chamfer 13 is provided at the edge of the side of the end cap 11 away from the insertion tube 1, and the cross-sectional area of the end cap 11 gradually increases from the side away from the insertion tube 1 to the other side. By arranging the arc chamfer 13, the insertion tube 1 can be guided to a certain extent, so as to guide during the insertion of the insertion tube 1 into the nasal cavity.
[0028] Please refer to Figure 1 , a plurality of grooves 14 are provided at intervals along the circumferential direction at the junction of the arc chamfer 13 and the side of the end cap 11 away from the insertion tube 1, and balls 12 are arranged in the grooves 14. The balls 12 are arranged at the junction of the arc chamfer 13 and the edge of the end cap 11 can increase the movement range of the balls 12, so as to cooperate with the arc chamfer 13 to guide the end of the insertion tube 1, so that the suction tube 2 can smoothly enter the airway from the glottis.
[0029] A buffer pad is arranged on the surface of the end cap 11, which can buffer during the process of inserting the insertion tube 1 into the nasal cavity, and prevent the surface of the end cap 11 from causing harm or discomfort to the inside of the patient's nasal cavity. Please refer to Figure 1 , the end of the light guide beam 4 is located near the camera 31. Such a setting can better provide light, facilitate the camera 31 to collect the position at the glottis, and facilitate guiding the adjustment of the insertion position of the insertion tube 1 so that the suction tube 2 can smoothly perform airway suction. The suction tube 2 is connected to a negative pressure aspirator. After the suction tube 2 smoothly enters the airway, the negative pressure aspirator is turned on to suck sputum, and the sputum suction effect is better.
[0030] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0031] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
