[0035] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application.

[0036] The inventors have discovered that current clinical solutions to problems such as contaminated ward environments, cross-infection, lack of splash protection, and absence of automatic switching functionality require pressing the ventilator's "standby" button to pause ventilation before operation. However, this method carries significant risks, as operators often forget to press the "start ventilation" button when reconnecting to the artificial airway, leading to suffocation. Furthermore, this method has a low execution rate and poor manual switching efficiency. Another approach is to use a closed suction catheter, but this method only addresses splashing during suctioning and does not solve the splashing problem when disconnected from the artificial airway. It is also expensive and lacks adaptability.

[0037] In view of this, see Figures 1-3 , Figure 1 A schematic diagram of the external structure of a splash-proof ventilator extension tube provided in an embodiment of this application; Figure 2 A cross-sectional view of the internal structure of a splash-proof ventilator extension tube provided in an embodiment of this application; Figure 3 This application provides a schematic diagram of a one-way valve structure for an extension tube of a splash-proof ventilator, which includes a sealing device 10, an elastic element 20, a sleeve 30, an air intake assembly 40, an air passage 50, a one-way valve structure 60, and a connector 70.

[0038] Among them, the elastic element 20 can be connected to the sealing device 10, the sleeve 30 is sleeved on the outside of the elastic element 20, one end of the sleeve 30 is connected to the sealing device 10, the air intake assembly 40 is connected to the outside of the sleeve 30, the air passage 50 is connected to the inside of the sleeve 30 and is connected to the elastic element 20, the one-way valve structure 60 is connected to the inner side wall of the end of the air passage 50 near the elastic element 20, the one-way valve structure 60 is provided with a through hole 601, which is used to connect the sealing device 10, the elastic element 20 and the air passage 50 to form a first passage, and the connector 70 can be a cylindrical structure with one end open. The cylindrical structure of the connector 70 is provided with a receiving groove inside, and the connector is sleeved on the outside of the air passage 50 through the receiving groove, and the open end face of the connector 70 is connected to the sleeve 30.

[0039] The above-mentioned features, through the installation of the sealing device 10 and the one-way valve structure 60, can prevent the splashing of contaminants during endotracheal intubation, ensuring airtightness during endotracheal intubation. While ensuring the normal operation of suctioning and fiberoptic bronchoscopy, it prevents the splashing of condensate containing pathogenic microorganisms in the ventilator tubing, ensuring the safety and accuracy of the surgery and effectively avoiding cross-infection.

[0040] In this embodiment, connector 70 can be a detachable oxygen connector, and the top of the detachable oxygen connector can have a detachable threaded connection. Specifically, the threaded connection method can be:

[0041] The detachable oxygen connector has a protruding first thread. The sleeve 30 has a hollow structure. The bottom side of the inner wall of the sleeve 30 has a second thread that matches the first thread. The detachable oxygen connector is inserted into the sleeve 30 and rotated. The detachable oxygen connector and the sleeve 30 are detachably threaded together by the first thread and the second thread.

[0042] The standard endotracheal intubation interface 701 is located inside the detachable oxygen connector 70. Its inner wall has a spiral groove structure and is screwed onto the outside of the lower section of the ventilation tube 50. It is used to connect to the artificial airway connector and acts as an adapter.

[0043] In the embodiments of this application, see also Figure 2 The upper inner wall of the detachable oxygen connector is equipped with a ventilation line limiting ring 703. When the sleeve 30 and the connector 70 are connected, the ventilation line limiting ring 703 locks the ventilation line 50, thereby preventing the ventilation line 50 from coming out, limiting the maximum vertical movement of the ventilation line 50, and preventing gas from escaping.

[0044] The sealing device 10 may include a cap 101 and a flip-top plug 102. The cap 101 may have a channel, and the flip-top plug 102 can be movably inserted into the channel. Opening the flip-top plug 102 allows for operations such as sputum suction and fiberoptic bronchoscopy.

[0045] Furthermore, as a crucial component, the cap 101 offers flexibility in material selection. It can be made of either silicone rubber or polyurethane. Silicone rubber is renowned for its excellent resistance to high and low temperatures, good flexibility, and sealing properties, ensuring that the cap 101 maintains stable performance in various environments. Polyurethane, on the other hand, possesses high strength, wear resistance, and excellent elasticity, allowing the cap 101 to withstand greater pressure and friction during use, thus extending its service life.

[0046] In this embodiment, an elastic element limiting ring 301 is connected to the inner wall of the sleeve 30. One end of the elastic element limiting ring 301 is connected to the flip-top plug 102, and the other end of the elastic element limiting ring 301 is connected to the elastic element 20. The elastic element 20 is engaged with the elastic element limiting ring 301 on the upper inner wall of the sleeve 30 and the top of the ventilation pipe 50. After the artificial airway is connected, the ventilation pipe 50 is squeezed and moves upward, the elastic element 20 contracts, and the vent hole 502 of the ventilation pipe 50 communicates with the air intake assembly 40, and mechanical ventilation begins. When the connection with the artificial airway is disconnected, the elastic element 20, due to its recovery characteristics, drives the ventilation pipe 50 downward with elastic recoil force, forming a misalignment for sealing. Therefore, the elastic element 20 provides power for the automatic switching of this utility model and provides space for the compression and movement of the ventilation pipe 50.

[0047] In view of this, the inner wall of the sleeve 30 is also connected to two protruding fixing strips 302 parallel to the ventilation pipe 50, and the two protruding fixing strips 302 are symmetrically positioned, cleverly forming a stable support structure for the ventilation pipe 50. A fixing groove 501 is also provided on the outer wall of the ventilation pipe 50 at a position corresponding to the protruding fixing strips 302, which connects with the corresponding protruding fixing strips 302 on the inner wall of the sleeve 30. After connection, the ventilation hole 502 of the ventilation pipe 50 can be aligned with the oxygen channel 401, thus fixing its position and preventing displacement.

[0048] In addition, the air intake assembly 40 includes an oxygen channel 401, a connecting tube 402, and an oxygen source connector 403. The connecting tube 402 can be a spiral connecting hose. One end of the spiral connecting hose is connected to the side wall of the inner sleeve 30 via the oxygen channel 401 and is internally connected. One end of the spiral connecting hose is connected to the Y-shaped connector of the ventilator tubing via the oxygen source connector 403, which allows mechanical ventilation and oxygen therapy to be carried out smoothly. At the same time, the branch design of the Y-shaped connector also facilitates the simultaneous connection of other medical devices or the provision of multiple oxygen supplies, improving the flexibility and efficiency of medical operations.

[0049] In this embodiment, the ventilation pipe 50 has a ventilation hole 502 on its side wall to connect the ventilation pipe 50 with the air intake component 40 to form a second passage. At the same time, the top of the ventilation pipe 50 has a groove to hold a one-way valve structure 60. When connected to an artificial airway, if it is necessary to open the flip-top plug 102 on the cap 101 for suctioning, fiberoptic bronchoscopy, etc., the connecting pipe 403 is connected to the ventilation hole 502, and the gas can be sprayed from the top of the ventilation pipe 50 at the position of the flip-top plug 102. The through hole 601 in the one-way valve structure 60 is a cross-shaped structure. The one-way valve structure 60 is located at the top of the ventilation pipe 50 to prevent such spraying.

[0050] A grip 702 is specially designed on the outer side of the connector 70. This grip 702 not only provides the user with a stable grip point, but also cleverly incorporates several anti-slip grooves 7021. The presence of these anti-slip grooves 7021 greatly increases the friction between the user's hand and the grip 702, ensuring that the user can easily and stably grip the connector 70 even in wet or oily environments. The main function of the grip 702 is to facilitate the user in unscrewing the connector 70, whether for connection or disassembly.
