Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an endotracheal cannula with a secretion cleaning function. Background Art

[0002] Endotracheal intubation is a crucial and effective rescue device in clinical emergency treatment. It ensures the patient's breathing safety during surgery and is connected to a ventilator for assisted breathing. In critically ill patients, for those who are unable to breathe spontaneously or whose spontaneous breathing is difficult to maintain, endotracheal intubation is connected to a ventilator for assisted breathing, ensuring the patient's most basic breathing needs.

[0003] After the tracheal intubation, the existing tracheal tubes mostly have only one breathing cavity for breathing support. When the secretions near the tracheal tube need to be cleaned, it is usually necessary to insert the suction tube directly into the breathing cavity and then clean the secretions as a whole. After the suction tube is inserted, it is easy to cause the overall narrowing of the breathing cavity. The overall operation is relatively cumbersome and cannot well meet the overall working requirements of the tracheal intubation. Therefore, the present application provides a tracheal intubation with a secretion cleaning function to meet the needs. Utility Model Content

[0033] like Figure 1 and Figure 2 As shown, the embodiment of the present utility model provides an endotracheal intubation with a secretion cleaning function, including an endotracheal intubation body 1, wherein an air guide cavity 14 and a sputum suction channel 13 are respectively opened inside the endotracheal intubation body 1 from top to bottom, a protruding block 141 is provided at the bottom of one end of the endotracheal intubation body 1, one end of the sputum suction channel 13 is arranged at the protruding block 141, and three sputum suction channels 13 are equidistantly provided. A guiding tube 11 is slidingly provided inside the sputum suction channel 13 in the middle, and a sputum suction seat 12 is fixed at one end of the guiding tube 11, and a first sputum suction port 121 and a second sputum suction port 122 are opened on the sputum suction seat 12. A fixing seat 4 is installed at the end of the endotracheal intubation body 1 away from the air guide cavity 14, and a protruding seat 7 is provided at the outer edge of one end of the endotracheal intubation body 1 corresponding to the fixing seat 4, and a clamping seat 9 is installed on one protruding seat 7, and the end of the guiding tube 11 away from the sputum suction seat 12 extends through the clamping seat 9, and a sputum suction tube 10 is installed at the end of the guiding tube 11 passing through the clamping seat 9.

[0034] By cooperating between the sputum suction channel 13 provided at the bottom of the endotracheal tube body 1 and the retractable guiding tube 11 and the sputum suction seat 12, a separate channel for the passage of sputum can be provided during operation. During subsequent sputum suction work, the sputum suction device pipe can be prevented from being extended into the respiratory cavity for suction, thereby affecting the respiratory work and causing the overall narrowing of the respiratory cavity. By means of the retractable guiding tube 11, the sputum suction seat 12 can be extended into the sputum position for suction when the sputum is still a certain distance away from one end of the endotracheal tube body 1, thereby preventing the sputum from being blocked at the corresponding position of the trachea and unable to be effectively sucked out, thereby improving the overall practicality of the device.

[0035] There are several first suction ports 121, and the several first suction ports 121 are arranged in a circular array with the center of the suction seat 12 as the center. There are several second suction ports 122, and the several second suction ports 122 are arranged in a circular array at the end of the suction seat 12 with the axis of the suction seat 12 as the center.

[0036] By coordinating the first suction port 121 and the second suction port 122, etc., the suction seat 12 can effectively absorb and clean sputum in different directions during operation, and try to avoid the situation where some sputum positions are not fully absorbed.

[0037] The outer edge of the endotracheal tube body 1 is engraved with scale lines 16, and the zero scale of the scale lines 16 is located at the end of the endotracheal tube body 1 close to the airbag 2. The scale lines 16 provided on the endotracheal tube body 1 can facilitate the effective determination of the overall insertion of the endotracheal tube body 1 during operation through the scales thereon, thereby avoiding problems such as the inability to effectively determine the overall position of the endotracheal tube body 1.

[0038] like Figure 1 and Figure 3 As shown, a camera 15 is installed at the inner top of the air guide cavity 14, and a wire 151 is installed on a protruding seat 7. The wire 151 is electrically connected to the camera 15. Through the set camera 15, the overall situation at the corresponding position of the tracheal tube body 1 can be effectively visually observed during operation.

[0039] The end of the endotracheal tube body 1 away from the protruding block 141 is provided with a mounting seat 3, a threaded connection seat 6 is threadedly installed on the mounting seat 3, a protruding plate 5 is fixed to the end of the threaded connection seat 6 away from the mounting seat 3, and a fixing seat 4 is fixed to the end of the protruding plate 5 away from the threaded connection seat 6. The fixing seat 4 is connected to the threaded connection seat 6, and a through hole is opened on the protruding plate 5, and two through holes are symmetrically opened.

[0040] By providing the fixing seat 4, it can be conveniently connected to the ventilator as a whole during operation, thereby ensuring that the endotracheal tube body 1 can stably provide breathing during subsequent operation.

[0041] like Figure 1 and Figure 4 As shown, the endotracheal tube body 1 has an airbag 2 mounted on the outer edge of one end near the protruding block 141. An inflation cavity 21 is reserved between the endotracheal tube body 1 and the airbag 2. An air inlet pipe 22 is provided on the endotracheal tube body 1 corresponding to the inflation cavity 21. An inflation tube 8 is mounted inside the endotracheal tube body 1. A protruding seat 7 extends from one end of the inflation tube 8, and the inflation tube 8 communicates with the air inlet pipe 22. A plurality of air inlet pipes 22 are provided, and are evenly spaced within the inflation cavity 21.

[0042] By providing the airbag 2 , the airbag 2 can be expanded as a whole during operation, and then the airbag 2 is snap-fitted and installed at the corresponding trachea, thereby completing the overall preliminary positioning process of the tracheal tube body 1 .

[0043] The working principle of the technical solution provided by this utility model is as follows:

[0044] During operation, the endotracheal tube is inserted and installed in the corresponding patient's trachea, and is supported as a whole inside the inflation tube 8, and one end of the airbag 2 is clamped and installed in the corresponding trachea, thereby completing the overall preliminary positioning of the endotracheal tube body 1.

[0045] The camera 15 is used to effectively understand the overall tracheal condition of the patient. When suction is required, the suction device is connected to the suction tube 10, and the sputum is cleared through the overall suction at the suction channel 13. When the sputum is still some distance away from the air guide cavity 14, the connector 9 is removed, and the suction tube 10 continues to be pushed inward to move the guide tube 11 as a whole and extend it, and then the sputum at the corresponding position is suctioned through the first suction port 121 and the second suction port 122 thereon to avoid insufficient suction. The tracheal condition at the air guide cavity 14 is detected through the camera 15, and the fixing seat 4 is connected to the ventilator to assist the patient in breathing during operation.

[0046] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
