Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an anti-falling tracheal tube device. Background Art

[0002] Endotracheal intubation is a technique that uses a specially designed endotracheal tube to insert into the endotracheal tube through the glottis. It is used to open the patient's airway, provide oxygen ventilation and oxygen supply, maintain breathing, and avoid airway obstruction, aspiration, etc. Endotracheal intubation is widely used. It is often used in surgical departments to keep patients under general anesthesia breathing during surgery, making it easier for anesthesiologists to perform anesthesia and surgeons to perform surgical operations. It is also used in non-surgical departments to treat respiratory failure, airway obstruction, respiratory infections, and other diseases.

[0003] However, in actual clinical practice, the intubation process often presents numerous uncertainties that can affect the stability of the tubing connection. These include unplanned tube removal due to restless patients, the surgeon's positional shift during surgery, changes in the position of patients undergoing general anesthesia, traction on the tubing due to changes in the operating table angle, and the direct influence of the surgeon's surgical manipulation. These factors can easily lead to the connection between the endotracheal tube and the threaded tubing becoming loose or detached. If discovered in time, the anesthesiologist can manually connect the tubing, contaminating the sterile area and requiring the surgery to continue after re-disinfection and draping, wasting time and resources. Failure to discover these issues in time can lead to uncontrollable consequences, the severity of which is directly proportional to the time it takes to remove the tubing. Therefore, ensuring the airtightness and integrity of the respiratory circuit is crucial.

[0046] In some possible embodiments, one end of the first clamping groove 211 is opened along the outer end of the first connecting short tube 21, so that the outer end of the first connecting end tube is in the shape of an open tube clamp, and the outer end of the first connecting end tube is the end away from the filter 2; one end of the second clamping groove 221 is opened along the outer end of the second connecting short tube 22, so that the outer end of the second connecting short tube 22 is in the shape of an open tube clamp, and the outer end of the second connecting short tube 22 is the end away from the filter 2.

[0047] Specifically, by configuring the outer end of the first connecting short tube 21 to be in the shape of an open tube clamp, the tube clamp-like structure has an elastic clamping force, and a plug-in connection is established between the tracheal tube 2 and the first connecting end tube 21. This improves the clamping force between the first connecting end tube 21 and the tracheal tube 2, making the connection between the two more stable and secure. The open tube clamp-like connection of the second connecting short tube 22 is similar to the above.

[0048] In some possible embodiments, a first circular groove 212 is provided at the other end of the first snap-fitting groove 211, and the width of the first snap-fitting groove 211 is smaller than the diameter of the first boss 11 and the diameter of the first circular groove 212, and the diameter of the first boss 11 is adapted to the diameter of the first circular groove 212, so that the first boss 11 slides along the first snap-fitting groove 211 into the first circular groove 212 and is snap-fitted and fixed; a second circular groove 222 is provided at the other end of the second snap-fitting groove 221, and the width of the second snap-fitting groove 221 is smaller than the diameter of the second boss 31 and the diameter of the second circular groove 222, and the diameter of the second boss 31 is adapted to the diameter of the second circular groove 222, so that the second boss 31 slides along the second snap-fitting groove 221 into the second circular groove 222 and is snap-fitted and fixed.

[0049] Specifically, if Figure 4 As shown, by the provision of the first circular groove 212, after the first protrusion 11 slides into the first clamping groove 211, the first connecting short tube 21 has an elastic clamping force of a tube clamp-like structure, so the first protrusion 11 can fall into the first circular groove 212 adapted thereto and be clamped and fixed, thereby preventing the first protrusion 11 from slipping out of the first clamping groove 211, thereby improving the connection stability between the tracheal tube 1 and the filter 2; by the provision of the second circular groove 222, after the second protrusion 31 slides into the second clamping groove 221, due to the elastic clamping force of the second connecting short tube 22 has a tube clamp-like structure, the second protrusion 31 can fall into the second circular groove 222 adapted thereto and be clamped and fixed, thereby preventing the second protrusion 31 from slipping out of the second clamping groove 221, thereby improving the connection stability between the threaded tube 3 and the filter 2.

[0050] In some possible implementations, the anti-falling tracheal tube device further includes two reinforcement hoops 12 , which are respectively sleeved on the first connecting short tube 21 and the second connecting short tube 22 .

[0051] Specifically, since the tube clamp structure has a certain possibility of collapse, and the first protrusion 11 and the second protrusion 31 have a possibility of falling out from the first circular groove 212 and the second circular groove 222, the provision of the reinforcement hoop 12 can further strengthen the clamping force of the first connecting short tube 21 and the second connecting short tube 22, thereby improving the connection stability between the tracheal tube 1, the filter 2 and the threaded tube 3.

[0052] In some possible embodiments, the reinforcement hoop 12 includes a tightening belt 121, a fixing sleeve 122 and a turning handle 123. One end of the tightening belt 121 is fixedly connected to the lower part of the fixing sleeve 122, and the upper part of the fixing sleeve 122 is movably connected to the front end of the turning handle 123 so that the turning handle 123 and the fixing sleeve 122 can rotate relative to each other along the axial direction of the turning handle 123; a thread is provided at the front end of the turning handle 123, and a plurality of adjustment holes are provided in the middle part of the tightening ring, and the plurality of adjustment holes are adapted to the thread. The other end of the tightening ring passes through the lower part of the fixing sleeve 122 and is threadedly connected to the turning handle 123.

[0053] Specifically, if Figure 4 As shown, one end of the fastening belt 121 is connected to the fixing sleeve 122, and the other end of the fastening belt 121 passes through the fixing sleeve 122 to form an annular structure that is sleeved on the first connecting short tube 21 and the second connecting short tube 22 at both ends of the filter 3, and the other end of the fastening belt 121 is driven to move by the turning handle 123 located on the upper part of the fixing sleeve 122 to adjust the diameter of the annular structure, thereby adjusting the fastening degree of the first connecting short tube 21 and the second connecting short tube 22; wherein, the front end of the turning handle 123 is provided with a thread, and the middle part of the fastening ring is provided with a plurality of adjustment holes, and the plurality of adjustment holes are adapted to the thread, that is, the teeth of the thread can fall into the plurality of adjustment holes accordingly, and when the thread rotates, it falls from the front adjustment hole into the rear adjustment hole, driving the fastening belt 121 to move to adjust the diameter of the annular structure.

[0054] In some possible embodiments, the tracheal tube 1 further includes a conversion socket 13, one end of which is connected to one end of the tracheal tube 1, and a first boss 11 is provided at the other end of the conversion socket 13, and the other end of the conversion socket 13 is detachably engaged with the first engaging groove 211 via the first boss 11; wherein the size of one end of the conversion socket 13 is adapted to the size of the tracheal tube 1, and the size of the other end of the conversion socket 13 is adapted to the size of the first connecting short tube 21.

[0055] Specifically, since the diameter of the first connecting short tube 21 of the filter 3 is usually not compatible with the diameter of the tracheal tube 1 through which the patient needs to input gas, and does not conform to the diameter of the tracheal tube 1 required by the patient, the provision of the conversion socket 13 can provide a connecting component connected to the filter 3 for tracheal tubes 1 or extension tubes of different lengths, thereby improving the practicality of the device.

[0056] In some possible implementations, anti-slip pads are provided on the inner walls of the first connecting short pipe 21 and the second connecting short pipe 22 .

[0057] Specifically, the provision of the anti-slip pad further improves the connection stability between the tracheal tube 1 , the filter 2 and the threaded tube 3 , thereby preventing them from falling off from the first connecting short tube 21 and the second connecting short tube 22 .

[0058] In some possible implementations, an inflatable balloon 14 is provided at the other end of the tracheal tube 1 , and the inflatable balloon is connected to an insufflation tracheal tube 15 , which is in communication with the insufflation balloon 14 .

[0059] In some possible implementations, the fastening belt 121 , the fixing sleeve 122 , and the rotating handle 123 are all made of stainless steel.

[0060] Specifically, it is made of stainless steel to ensure the overall stability, durability and cleanliness of the reinforcement hoop 12, making it easy to be reused in clinical practice.
