Description

Technical Field

[0001] This utility model relates to the field of ventilator tubing equipment, specifically a filterable and splash-proof ventilator extension tube. Background Technology

[0002] Currently, the ventilator extension tubes used in the market only have an extension tube, allowing the tube port to function as a suction inlet. When the connection to the endotracheal tube is disconnected or the rubber stopper of the suction inlet is opened, the positive pressure causes condensate containing pathogenic microorganisms inside the ventilator tubing to splash out, contaminating the operator. Some of the splashes form aerosols that remain suspended in the air, polluting the ward environment, leading to cross-infection and the spread of infectious diseases. Therefore, they not only lack splash prevention but also do not have an automatic switching function. Currently, closed suction tubes are commonly used in clinical practice to address this problem, but this method only solves the splashing problem during suctioning and does not solve the splashing problem when disconnected from the artificial airway. Furthermore, it is expensive and lacks adaptability.

[0003] Therefore, how to solve the problems of pollutant splashing, environmental pollution and damage to ventilators during operation is an urgent issue to be addressed in the field of ventilator tubing equipment. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] The inventors have discovered that current clinical solutions to problems such as aerosol formation from splashes, which suspend air, contaminate the ward environment, and cause cross-infection, require pausing ventilation by pressing the ventilator's "standby" button before operation. However, this method carries significant risks, as operators often forget to restart ventilation when reconnecting 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 or the resulting gas pollution. It is also expensive and lacks adaptability.

[0040] In view of this, see Figure 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 a splash-proof ventilator extension tube according to an embodiment of the present application; the present application provides a filterable splash-proof ventilator extension tube, including a sealing device 10, an elastic element 20, a sleeve 30, a filter device 40, an air intake assembly 50, an air passage 60, a one-way valve structure 70, and a connector 80.

[0041] Among them, one end of 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 filter device 40 is connected to one side of the sleeve 30, the air intake assembly 50 is connected to the other side of the sleeve 30, the air passage 60 is located inside the sleeve 30 and is connected to the other end of the elastic element 20, and the one-way valve structure 70 is connected to the air passage 60; the connector 80 can be a cylindrical structure with one end open, the cylindrical structure of the connector 80 is provided with a receiving groove, the connector 80 is sleeved on the outside of the air passage 60 through the receiving groove, and the open end face of the connector 80 is connected to the sleeve 30.

[0042] Beneficial effects: By setting up a sealing device 10, a filtering device 40, and a one-way valve structure 70, this application can avoid the splashing of contaminants during endotracheal intubation and the problem of air pollution and damage to the ventilator caused by gases released during operation. It ensures airtightness during endotracheal intubation and prevents the splashing of condensate containing pathogenic microorganisms in the ventilator tubing while ensuring the normal functioning of suctioning and fiberoptic bronchoscopy. This ensures the safety and accuracy of the operation and effectively avoids cross-infection.

[0043] In this embodiment, connector 80 can be a detachable oxygen connector, and the top of the detachable oxygen connector can be a detachable threaded connection. Specifically, the threaded connection method can be:

[0044] 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.

[0045] The upper outer wall of the detachable oxygen connector has a gripping part 802. When the connector 80 needs to be disassembled, the gripping part 802 is rotated to easily unscrew the detachable oxygen connector. The standard endotracheal tube interface 801 is located inside the detachable oxygen connector. Its inner wall has a spiral groove structure and is screwed onto the outside of the lower section of the ventilation tube 60. It is used to connect to the artificial airway connector and acts as an adapter.

[0046] In this embodiment, a ventilation pipe limiting ring 803 is provided on the upper inner side wall of the detachable oxygen connector. When the sleeve 30 and the connector 80 are connected, the ventilation pipe limiting ring 803 locks the ventilation pipe 60, thereby preventing the ventilation pipe 60 from coming out, limiting the maximum vertical movement of the ventilation pipe 60, and preventing gas from escaping.

[0047] 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. In addition, as an important component, the cap 101 has flexibility in material selection. It can be made of either silicone rubber or polyurethane.

[0048] To prevent the gas released from the ventilator tubing from polluting the environment, a filter device 40 is also provided. The filter device 40 may include a filter 401 and a splash buffer channel 402. One end of the splash buffer channel 402 is connected to the sleeve 30, and the other end of the splash buffer channel 402 is connected to the filter 401. The gas in the ventilator tubing is discharged into the atmosphere through the filter 401, which neither pollutes the environment nor damages the ventilator. It has the functions of depressurization, filtration, and splash prevention.

[0049] In addition, you can refer to Figure 2 The inner wall of the sleeve 30 is connected to an elastic element limiting ring 301. One end of the elastic element limiting ring 301 is connected to the flip-top plug 102, and the other end is connected to an elastic element 20. The elastic element 20 is engaged between the elastic element limiting ring 301 on the upper inner wall of the sleeve 30 and the top of the ventilation pipe 60. After connecting to the artificial airway, the ventilation pipe 60 is compressed and moves upward, the elastic element 20 contracts, and the second vent 603 of the ventilation pipe 60 communicates with the air intake assembly 50, and mechanical ventilation begins. When the connection with the artificial airway is disconnected, the elastic element 20, due to its restorative properties, drives the ventilation pipe 60 downward with its elastic recoil force, forming a misalignment for sealing. The first vent 602 of the ventilation pipe 60 is connected to the splash buffer channel 402, and the released gas is discharged into the atmosphere through the filter 401. Therefore, the elastic element 20 provides power for the automatic switching of this utility model and provides compression and movement space for the ventilation pipe 60. In addition, since the elastic element 20 and the ventilation line 60 are both modularly designed, they can be cleaned and replaced after unscrewing the detachable oxygen connector. At the same time, the detachable oxygen connector is the main inlet for connecting the artificial airway connector.

[0050] In view of this, the inner wall of the sleeve 30 can also be connected with two protruding fixing strips 302 parallel to the ventilation pipe 60, and the two protruding fixing strips 302 are symmetrically positioned, cleverly forming a stable support structure for the ventilation pipe 60. A fixing groove 601 is also provided on the outer wall of the ventilation pipe 60 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 first vent hole 602 and the second vent hole 603 of the ventilation pipe 60 can correspond to the oxygen channel 501, and the symmetrical side holes of the first vent hole 602 can correspond to the splash buffer channel 402, thus fixing the position and preventing displacement.

[0051] In addition, the air intake assembly 50 may include an oxygen channel 501, a connecting tube 502, and an oxygen source connector 503. The connecting tube 502 may be a spiral connecting hose. One end of the spiral connecting hose is connected to the side wall of the inner tube 30 via the oxygen channel 501 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 503, so that mechanical ventilation and oxygen therapy can be carried out smoothly. At the same time, the branch design of the Y-shaped connector also makes it easy to connect other medical devices at the same time or to provide multiple oxygen supplies, improving the flexibility and efficiency of medical operations.

[0052] In the embodiments of this application, reference is made to Figure 2-3 The ventilation pipe 60 has two side holes on one side, which can be the first ventilation hole 602 and the second ventilation hole 603 from top to bottom. The other side also has a side hole that is symmetrical to the first ventilation hole 602 and corresponds to the splash buffer channel 402. At the same time, there are slots at the top of the ventilation pipe 60 and between the first ventilation hole 602 and the second ventilation hole 603, in which the first one-way valve structure 701 and the second one-way valve structure 702 are installed in sequence. When the connection with the artificial airway is disconnected and the flip-top plug 102 on the cap 101 is opened, the connecting pipe is connected to the first ventilation hole 602, and the gas can be splashed from the top of the ventilation pipe 60 at the position of the flip-top plug 102. Furthermore, the one-way valve structure 70 includes a first one-way valve structure 701 and a second one-way valve structure 702. The first one-way valve structure 701 is a cross-shaped one-way valve structure located at the top of the ventilation pipe 60 to prevent such splashing. The second one-way valve structure is also a cross-shaped one-way valve structure located between the first vent hole 602 and the first vent hole 602. When the artificial airway is disconnected, the ventilation pipe 60 moves downward, and the first vent hole 602 communicates with the splash buffer channel 402. At this time, the second one-way valve structure 702 can prevent a portion of the gas from splashing downward from the ventilation pipe 60 through the first vent hole 602.
