Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a respiratory circuit connector for respiratory critically ill patients that allows for sputum suction without the need for closed-loop endoscopy. Background Technology

[0002] In critically ill patients with respiratory diseases, bronchoscopy is often necessary after endotracheal intubation or when using non-invasive ventilators to help identify pathogens or make pathological diagnoses. However, bronchoscopy requires temporary disconnection of ventilator-assisted breathing, during which patients may experience hypoxia, dyspnea, and other conditions, forcing the interruption of the bronchoscopy and increasing the risk of respiratory failure. Most patients need to repeat the procedure multiple times to barely complete it. To address these difficulties in clinical practice, we have proposed a breathing circuit connector for closed-loop bronchoscopy suctioning in critically ill respiratory patients that eliminates the need for weaning. Summary of the Invention

[0003] The purpose of this invention is to provide a respiratory circuit connector for bronchoscopy suctioning in critically ill patients without the need for weaning, in order to solve the problem mentioned in the background art where patients need to temporarily disconnect from the ventilator during bronchoscopy, during which they may experience hypoxia and respiratory distress.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a respiratory circuit connector for endotracheal intubation and suctioning of critically ill respiratory patients without the need for closure endotracheal sputum removal, comprising a novel connector, an endotracheal tube interface fixedly connected to the outer side of the novel connector, a connecting tube fixedly connected to the upper end of the novel connector, an adjustment component provided inside the connecting tube, a connection port opened inside the adjustment component, and a protective component provided outside the connecting tube.

[0005] The adjustment assembly includes a first movable groove, an adjustment ring, an internal gear, a second movable groove, a rotating shaft, a pinion, and a limiting block. The outer surface of the connecting pipe has a first movable groove, the inside of which is an adjustment ring, and the inner side of which is an internal gear. The inside of the connecting pipe has a second movable groove, and the inside of which is arranged in a circular array of several rotating shafts. The outer side of each rotating shaft is provided with a pinion, and the bottom of each rotating shaft is provided with a limiting block.

[0006] Preferably, the protective assembly includes a connecting strip, a cover plate, and a piston. The connecting strip is fixedly connected to the bottom of the connecting pipe, the cover plate is fixedly connected to the top of the connecting strip, and the piston is fixedly connected to the outside of the cover plate. The diameter of the piston matches the inner diameter of the connecting port.

[0007] Preferably, the upper and lower sides of the adjusting ring are fixedly connected to limit rings, the adjusting ring is rotatably connected to the connecting pipe through the limit rings, the outer surface of the adjusting ring is fixedly connected with protrusions at equal intervals, the outer surface of the internal gear is fixedly connected to the inner wall of the adjusting ring, the rotating shaft is rotatably installed inside the second movable groove, the inside of the small gear is fixedly connected to the rotating shaft, the small gear and the internal gear mesh with each other, and the upper end of the limit block is fixedly connected to the bottom of the rotating shaft.

[0008] Preferably, four sets of elastic valves are fixedly connected inside the connecting tube, the four sets of elastic valves are located below the connecting port, and the four sets of elastic valves are made of silicone.

[0009] Preferably, a positioning hemisphere is fixedly connected to the bottom of the protrusion on the surface of a set of adjusting rings, a fixing ring is fixedly connected to the outside of the connecting tube, and two pairs of limiting hemispheres are fixedly connected to the surface of the fixing ring. The positioning hemisphere and the limiting hemisphere are elastic.

[0010] Preferably, the outer surface of the connecting tube is fixedly connected with scale lines, and the outer side of the adjusting ring is fixedly connected with an indicator arrow.

[0011] Preferably, the inner wall of the connecting strip is provided with a groove, and the inner diameter of the groove matches the adjusting ring.

[0012] Preferably, a toggle piece is fixedly connected to the outer side of the cover plate, and the connecting strip, cover plate, piston and toggle piece are all made of silicone.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This invention, through the setting of the adjustment component, allows for the simultaneous rotation of the adjustment ring, which drives the small gear and rotating shaft through the internal gear to rotate the micro-gear and the rotating shaft when performing endoscopy or suctioning on critically ill patients requiring endotracheal intubation for ventilation, thereby adjusting the inner diameter to the corresponding size. This allows for endoscopy or suctioning without stopping ventilation or disconnecting the ventilator connector, ensuring continuous ventilator ventilation and avoiding the risk of hypoxia.

[0015] 2. Through the setting of protective components, when not performing microscopic examination or suctioning, the piston at the cover plate is inserted into the connection port through the cooperation of the elastic valve, connecting strip, cover plate and piston. When the elastic valve is not inserted, the four sets of elastic valves automatically close, so that the device is in a sealed state, so as to avoid affecting the respiratory treatment. At the same time, it can prevent external dust from entering the device. Attached Figure Description

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see Figure 1-6This invention provides an embodiment of a respiratory circuit connector for bronchoscope suctioning in critically ill patients without the need for bronchial closure, comprising a novel connector 1, an endotracheal intubation interface 2 fixedly connected to the outer side of the novel connector 1, connecting the endotracheal intubation interface 2 to the breathing tube, and an adjustment component 4 for adjusting the connecting tube 3, allowing the insertion of a bronchoscope or suction catheter. The upper end of the novel connector 1 is fixedly connected to the connecting tube 3, and the adjusting component 4 is provided inside the connecting tube 3. The adjusting component 4 has a connection port 5 inside, and a protective component 7 is provided on the outer side of the connecting tube 3 to protect the interior of the connecting tube 3. The adjusting component 4 includes... The connecting pipe 3 includes a first movable groove 401, an adjusting ring 402, an internal gear 403, a second movable groove 404, a rotating shaft 405, a pinion 406, and a limiting block 407. The first movable groove 401 is provided on the outer surface of the connecting pipe 3. An adjusting ring 402 is provided inside the first movable groove 401. An internal gear 403 is provided on the inner side of the adjusting ring 402. The second movable groove 404 is provided inside the connecting pipe 3. Several sets of rotating shafts 405 are arranged in a circular array inside the second movable groove 404. A pinion 406 is provided on the outer side of the rotating shaft 405. A limiting block 407 is provided at the bottom of the rotating shaft 405.

[0026] This device, through the adjustment of component 4 and the protection component 7, solves the problem that patients may experience hypoxia and difficulty breathing during bronchoscopy when the ventilator is temporarily disconnected.

[0027] Furthermore, the protective component 7 includes a connecting strip 701, a cover plate 702, and a piston 703. The connecting strip 701 is fixedly connected to the bottom of the connecting pipe 3, and the cover plate 702 is fixedly connected to the top of the connecting strip 701. The diameter of the cover plate 702 is larger than that of the connection port 5, and the piston 703 is fixedly connected to the outer side of the cover plate 702. The diameter of the piston 703 matches the inner diameter of the connection port 5. Figure 3 As shown, this structure is used to seal the connection port 5 by inserting the piston 703 at the cover plate 702 into the connection port 5, so as to keep the device in a sealed state and avoid affecting the patient's breathing. At the same time, it can prevent dust from entering the inside of the connection tube 3 and prevent it from being brought into the patient's body during insertion, thus avoiding infection.

[0028] Furthermore, limiting rings are fixedly connected to the upper and lower sides of the adjusting ring 402. The adjusting ring 402 is rotatably connected to the connecting pipe 3 through the limiting rings. Protrusions are fixedly connected at equal intervals on the outer surface of the adjusting ring 402. The outer surface of the internal gear 403 is fixedly connected to the inner wall of the adjusting ring 402. The rotating shaft 405 is rotatably installed inside the second movable groove 404. The interior of the pinion 406 is fixedly connected to the rotating shaft 405. The pinion 406 meshes with the internal gear 403. The upper end of the limiting block 407 is fixedly connected to the bottom of the rotating shaft 405. The limiting block 407 is willow leaf shaped. Figure 5As shown, this structure is used to rotate the adjusting ring 402, which, under the action of the meshing of the internal gear 403 and the pinion 406, drives multiple sets of rotating shafts 405 and limiting blocks 407 to rotate synchronously, adjusting the inner diameter of the connection port 5 to match the bronchoscope or suction tube, so that the bronchoscope or suction tube can be inserted just right, avoiding the opening size being uniform and only allowing one type of tube to be inserted, thus improving the applicability of the device.

[0029] Furthermore, four sets of elastic valves 6 are fixedly connected inside the connecting tube 3. These four sets of elastic valves 6 are located below the connecting port 5 and are made of silicone. Figure 3 As shown, this structure is used to push the four sets of elastic valves 6 toward the inside of the connecting tube 3 when inserting a bronchoscope or suction catheter. After the inner diameter of the connecting port 5 is fixed, the pushing range of the four sets of elastic valves 6 is limited, so that the elastic valves 6 fit with the inserted bronchoscope or suction catheter. When removed, due to the elastic effect, the four sets of elastic valves 6 return to their original position and fit together, so that the inside of the connecting tube 3 remains sealed.

[0030] Furthermore, a positioning hemisphere 8 is fixedly connected to the bottom of the protrusion on the surface of a set of adjusting rings 402, and a fixing ring 9 is fixedly connected to the outside of the connecting tube 3. Two pairs of limiting hemispheres 10 are fixedly connected to the surface of the fixing ring 9. The positioning hemisphere 8 and the limiting hemisphere 10 are elastic. Figure 6 As shown, this structure is used to rotate the positioning hemisphere 8 along the fixed ring 9 when the adjusting ring 402 is rotated. When it rotates to contact the limiting hemisphere 10, the user feels resistance, indicating that the designated position has been reached. Continuing to rotate the adjusting ring 402 causes the positioning hemisphere 8 to press against the limiting hemisphere 10, rotating the positioning hemisphere 8 between the two sets of limiting hemispheres 10. At this time, the inner diameter of the connecting port 5 matches the bronchoscope. Continuing to rotate the adjusting ring 402 until it contacts the second pair of limiting hemispheres 10, similarly, the positioning hemisphere 8 is rotated between the two sets of limiting hemispheres 10. At this time, the inner diameter of the connecting port 5 matches the suction tube, making it easy to position it in the matching position and avoiding gaps between the tubes after multiple rotations.

[0031] Furthermore, a scale line 11 is fixedly connected to the outer surface of the connecting pipe 3, and an indicator arrow 12 is fixedly connected to the outer side of the adjusting ring 402. For example... Figure 6 As shown, this structure is used to drive the indicator arrow 12 when the adjusting ring 402 rotates, and when rotated to the appropriate position, it indicates the corresponding scale line 11, which is convenient for connecting with pipes of different sizes and marking them for easy use next time, thus improving the applicability of the device.

[0032] Furthermore, the inner wall of the connecting strip 701 is provided with a groove 13, the inner diameter of which matches the protrusion on the surface of the adjusting ring 402. For example... Figure 4As shown, this structure is used so that when the piston 703 is inserted into the connection port 5, the cover plate 702 fits against the outer surface of the connecting pipe 3, so that the slot 13 fits against the surface of the adjusting ring 402, thereby fixing the adjusting ring 402 and preventing the adjusting ring 402 from rotating.

[0033] Furthermore, a toggle piece 14 is fixedly connected to the outer side of the cover plate 702. The diameters of the toggle piece 14 and the cover plate 702 are larger than the diameter of the connecting tube 3, facilitating the insertion or removal of the cover plate 702 via the toggle piece 14. The connecting strip 701, cover plate 702, piston 703, and toggle piece 14 are all made of silicone. Figure 4 As shown, this structure is designed to use silicone material with a certain degree of toughness to ensure that the cover plate 702 fits tightly against the inner wall of the connection port 5.

[0034] Working principle: When using, such as Figure 1 and Figure 3 As shown, first connect the bottom of the new connector 1 to the endotracheal tube, then connect the endotracheal tube interface 2 to the breathing tube. When bronchoscopy is required, pull the lever 14 to remove the piston 703 from the connection port 5. Figure 5 and Figure 6 As shown, rotating the adjusting ring 402 causes the internal gear 403 and the small gear 406 to mesh, driving multiple sets of rotating shafts 405 and limiting blocks 407 to rotate synchronously. Simultaneously, the positioning hemisphere 8 rotates along the fixing ring 9. When it contacts the limiting hemisphere 10, the user feels resistance, indicating that the designated position has been reached. Continuing to rotate the adjusting ring 402 causes the positioning hemisphere 8 to press against the limiting hemisphere 10, rotating the positioning hemisphere 8 between the two sets of limiting hemispheres 10. At this point, the inner diameter of the connecting port 5 matches the bronchoscope. The bronchoscope is then inserted into the connecting port 5 from the connecting tube 3. When inserting the suction catheter, the adjusting ring 402 must be rotated further until it contacts the second pair of limiting hemispheres 10. Similarly, the positioning hemisphere 8 is rotated between the two sets of limiting hemispheres 10. At this point, the inner diameter of the connecting port 5 matches the suction catheter. Figure 3 As shown, when inserting a bronchoscope or suction catheter, the four sets of elastic valves 6 are pushed towards the inside of the connecting tube 3. After the inner diameter of the four sets of elastic valves 6 is fixed in the connecting port 5, the pushing range is limited, allowing the elastic valves 6 to fit against the inserted bronchoscope or suction catheter for testing or suctioning. After testing or suctioning is completed, when removing the device, due to the elasticity of the elastic valves 6, the four sets of elastic valves 6 return to their original position and fit against each other. The piston 703 at the cover plate 702 is inserted into the connecting port 5 to seal the connecting port 5, keeping the device in a sealed state and preventing dust from entering the inside of the connecting tube 3. Simultaneously, as... Figure 4 and Figure 5As shown, the adjusting ring 402 is rotated back to its original position, and the cover plate 702 is attached to the outer surface of the connecting pipe 3, so that the slot 13 is attached to the surface of the adjusting ring 402, thereby fixing the adjusting ring 402 and preventing the adjusting ring 402 from rotating. The above is the complete working principle of the present invention.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
