Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ventilator pipelines, and particularly relates to an extension tube for a ventilator. Background Technique
[0002] A ventilator is a medical device that can send air containing oxygen into the lungs and discharge the gas containing carbon dioxide out of the body, helping the respiratory system to complete ventilation. It mainly applies pressure directly at the opening of the respiratory tract. When inhaling, the gas is pressurized and pressed into the alveoli, and when exhaling, the gas is discharged out of the body passively with the chest and lungs recovered. According to the way of switching from inhalation to exhalation, it can be divided into three categories: pressure switching, volume switching, and time switching. In modern medicine, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia during surgery, respiratory management, respiratory support treatment, and first aid resuscitation, and occupy a very important position in the medical field. Ventilator extension tubes are commonly used in the mechanical ventilation of invasive patients. As long as a patient admitted for invasive ventilation is treated, a ventilator extension tube will be prepared for him.
[0003] When the existing extension tubes are connected, the connection method is mostly insertion connection. With a single insertion connection structure, its resistance to external forces is not good. When external forces act on the extension tube accidentally, the connection part of the extension tube is prone to separation and disconnection, affecting the normal working state of the ventilator. When inserting a suction tube, there is likely to be a gap between the suction tube and the suction port, affecting the airtightness of the extension tube airway. Content of the Utility Model

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: an extension tube for a ventilator, including an extension pipeline 1, the extension pipeline 1 can freely stretch and bend, one end of the extension pipeline 1 is provided with a connector 2, the other end of the extension pipeline 1 is provided with a socket 3, one end of the socket 3 is provided with a sputum suction port 4, a manual valve 7 is arranged at the sputum suction port 4, the other end of the socket 3 is provided with a socket 5, a cap 6 is arranged on the sputum suction port 4, an adjusting sleeve 21 is sleeved on the connector 2 in a threaded manner, an elastic reinforcement strip 22 is arranged on the connector 2, an elastic cloth 41 is arranged on the inner side surface of the sputum suction port 4, and an elastic ring 42 is arranged inside the elastic cloth 41.
[0025] Among them, one end of the socket 3 is connected to one end of the extension pipeline 1, one end of the socket 3 is connected to the sputum suction port 4, one end of the socket 3 is connected to the socket 5. When the sputum suction pipeline is not plugged in, the sputum suction port 4 is blocked by the cap 6. The socket 3 is rotatably connected to the extension pipeline 1, and the socket 5 is rotatably connected to the socket 3. The socket 3 can rotate 360 degrees relative to one end of the extension pipeline 1, and the socket 5 can rotate 360 degrees relative to one end of the socket 3, improving the flexibility during use.
[0026] Among them, an elastic cloth 41 and an elastic ring 42 are added inside the sputum suction port 4. Both the elastic cloth 41 and the elastic ring 42 have a certain elasticity and can produce a certain degree of elastic deformation. When the sputum suction pipeline is inserted through the sputum suction port 4, the elastic cloth 41 and the elastic ring 42 rely on their own elastic actions to undergo corresponding elastic deformations, so that the inner ring of the elastic ring 42 closely adheres to the outside of the sputum suction pipeline, sealing the sputum suction pipeline and the sputum suction port 4, and hermetically sucking sputum, thereby ensuring the airtightness of the airway of the extension pipeline 1.
[0027] Among them, when not performing sputum suction, the cap 6 blocks the sputum suction port 4, and the manual valve 7 is in a closed state, blocking the passage of the sputum suction port 4. When it is necessary to plug in the sputum suction pipeline, the cap 6 is removed to expose the sputum suction port 4. At this time, the air circuit is sealed by the closed manual valve 7, and one end of the sputum suction pipeline is inserted through the sputum suction port 4. The elastic ring 42 closely adheres to and seals the outside of the sputum suction pipeline, and then the manual valve 7 is manually opened. After the manual valve 7 is opened, an external force is continuously applied to insert the sputum suction pipeline to the specified position. During the insertion of the sputum suction pipeline, the entire intubation process is in a sealed state, effectively ensuring the airtightness of the extension pipeline 1.
[0028] When pulling out the sputum suction pipeline, first move one end of the sputum suction pipeline to the upper part of the manual valve 7, then manually close the manual valve 7 to seal the air circuit, and finally completely pull out the sputum suction pipeline and cover the cap 6. The pipe pulling process is in a sealed state, effectively ensuring the airtightness of the extension pipeline 1.
[0029] Among them, an elastic reinforcement strip 22 and an adjustment sleeve 21 are added to the connector 2 of the extension pipeline 1. The elastic reinforcement strip 22 and the adjustment sleeve 21 form a reinforcement assembly. When the connector 2 is inserted and connected, manually rotate the adjustment sleeve 21. The adjustment sleeve 21 rotates and moves along the axis direction of the connector 2. During the movement of the adjustment sleeve 21, the extrusion inclined surface 24 of the adjustment sleeve 21 applies an extrusion force to the elastic reinforcement strip 22, forcing the elastic reinforcement strip 22 to generate elastic deformation inward. The occlusal reinforcement at the connection is realized through the elastic reinforcement strip 22, thereby improving the structural strength of the connection of the connector 2, enhancing the anti-external force effect at the connection, making it not easy to separate and disconnect, ensuring the normal operation of the ventilator, and eliminating potential safety hazards caused by the easy disconnection at the connection.
[0030] Among them, the elastic cloth 41 is set as an annular structure, and the elastic ring 42 is fixedly arranged on the inner ring of the elastic cloth 41. Both the elastic cloth 41 and the elastic ring 42 have certain elasticity and can generate a certain degree of elastic deformation.
[0031] Among them, the cap 6 is fixedly connected to the sputum suction port 4 in a snap-fit manner. The connection method is simple, and a certain external force can be applied to separate the cap 6 and the sputum suction port 4.
[0032] Among them, three groups of elastic reinforcement strips 22 are provided. The three groups of elastic reinforcement strips 22 are evenly distributed at intervals along the circumferential direction of the connector 2. The three groups of elastic reinforcement strips 22 achieve three-point fixation and occlusal fixation from multiple directions.
[0033] Among them, occlusal protrusions 23 are provided on the inner side surfaces of the three groups of elastic reinforcement strips 22. When the elastic reinforcement strip 22 moves, the occlusal protrusions 23 move synchronously with the elastic reinforcement strip 22, and the occlusal protrusions 23 are in close contact with the occlusal position.
[0034] Among them, an internal thread groove 25 is provided on the inner side surface of the adjustment sleeve 21, an external thread groove is provided on the outer side surface of the connector 2, and the adjustment sleeve 21 is threadedly connected to the connector 2. Applying a certain external force to the adjustment sleeve 21 can rotate the adjustment sleeve 21, and the position of the adjustment sleeve 21 is controlled by the rotation direction and the number of rotation turns.
[0035] Among them, one end of the inner side surface of the adjustment sleeve 21 is provided with an extrusion inclined surface 24, and the extrusion inclined surface 24 is in close contact with the outer side surface of the elastic reinforcement strip 22.
[0036] Among them, the socket 3 is set as a tee structure, making the extension pipeline 1 form a tee structure.
[0037] Among them, a plurality of anti-slip grooves are provided on the adjusting sleeve 21, which increases the contact friction when the hand contacts the adjusting sleeve 21.
[0038] Working principle: When in use, connect the extension pipeline 1, connect the connector 2 of the extension pipeline 1 to the ventilator pipeline, connect the socket 5 of the extension pipeline 1 to the tracheal intubation of the patient to connect the air path. After the connector 2 is inserted and connected, manually rotate the adjusting sleeve 21. The adjusting sleeve 21 moves while rotating along the axial direction of the connector 2. During the movement of the adjusting sleeve 21, the extrusion inclined surface 24 of the adjusting sleeve 21 applies an extrusion force to the elastic reinforcement strip 22, forcing the elastic reinforcement strip 22 to generate elastic deformation inward, and realizing the bite reinforcement at the connection through the elastic reinforcement strip 22. When the suction pipeline is not inserted, the suction port 4 is blocked by the cap 6 and the manually operated valve 7 in the closed state. When suction is required, remove the cap 6. At this time, the air path is sealed by the manually operated valve 7 in the closed state. The suction pipeline is inserted into the suction port 4 for a certain distance. The elastic cloth 41 and the elastic ring 42 undergo corresponding elastic deformations by relying on their own elastic actions, so that the inner ring of the elastic ring 42 closely adheres to the outside of the suction pipeline, sealing the suction pipeline and the suction port 4. Then manually open the manually operated valve 7. After the manually operated valve 7 is opened, continue to apply an external force to insert the suction pipeline to the designated position. During the insertion of the suction pipeline, the whole intubation process is in a sealed state, effectively ensuring the airtightness of the extension pipeline 1, so as to ensure the airtightness of the airway of the extension pipeline 1, and then the suction pipeline is connected to the suction machine for use.
