AI Technical Summary
During the rescue of tracheal intubation, ordinary suction tubes are too thin and soft, making it difficult to suck out larger sputum or food residues. The use of the suction device to directly attract the end of the connecting tube to the pipe can easily cause throat bleeding and contamination of the connecting tube, and cannot be used continuously.
A new suction tube joint is designed, including the body, curved portion and expandable head end. The curved arc portion is convenient for crossing the pharyngeal cavity, and the head end can be expanded to form a funnel-like structure when needed to increase the suction area.
This new suction tube joint can suck out larger sputum or food residues faster, reducing damage to the patient's throat, prolonging the service life of the connecting tube, and reducing material consumption.

[0001] The utility model relates to the technical field of medical devices, in particular to a novel sputum suction tube joint for tracheal intubation of patients. Background Art
[0002] In clinical practice, when performing endotracheal intubation for rescue, patients often have relatively large sputum or food residues in their throats. Ordinary suction tubes are too thin and soft to suck them out. Therefore, in emergency situations, the end of the suction tube is often used to directly suction the patient. However, the connecting tube is relatively hard, and the shape of the tube mouth is not designed according to the shape of the throat, which can easily cause bleeding in the patient's throat and cause secondary injury.
[0003] At the same time, using the end of the suction device connecting tube to directly attract tracheal sputum or food residues will also cause the connecting tube to be contaminated and unable to meet the medical requirements for continued use. A new connecting tube needs to be replaced, which consumes a lot of materials.
[0004] Therefore, we propose a novel sputum suction tube connector for endotracheal intubation of patients. Utility Model Content

[0025] Embodiment 1
[0026] A novel sputum suction tube connector for endotracheal intubation of a patient, such as Figure 1 As shown, it includes a tube body 1, a connecting seat 4 and a negative pressure suction device connecting tube 5 which are integrally formed at one end of the tube body 1, and a side control hole 15 is opened on the side wall of the connecting seat 4 to connect the negative pressure suction device connecting tube 5 with the negative pressure suction device. When clearing foreign matter in the airway, the suction force is adjusted through the side control hole 15. The other end of the tube body 1 is bent to form an arc portion 2, which is more conducive to crossing the pharyngeal cavity. When inserted into the pharyngeal cavity, the direction of the sputum suction tube is easier to grasp. The other side of the arc portion 2 is integrally formed with a head end portion 3, and the distal end of the head end portion 3 expands outward to form a funnel-shaped structure. When absorbing larger sputum blocks, the expanded structure has a larger suction area and can expel foreign matter more quickly, thereby buying time for rescue.
[0027] The length of the head portion 3 is 20 mm, and the expanded distal end diameter is 25 mm.
[0028] The bending angle of the arc portion 2 is 35°, the bending radius is 60 mm, and the arc length of 2 is 35 mm.
[0029] The tube body 1 has a length of 260 mm and a diameter of 15 mm.
[0030] The tube body 1 is made of medical polymer materials, such as PVC, PE, etc.
[0031] In this embodiment, the negative pressure suction device connecting tube 5 is first connected to the negative pressure suction device, and the size and opening of the negative pressure at the head end 3 are controlled through the side control hole 15. The bending of the curved portion 2 makes it easier to grasp the direction and operate the suction tube when crossing the pharyngeal cavity. The expansion of the head end 3 can increase the suction area. In cases of rescue and first aid, compared with traditional flat-mouthed suction tubes, larger sputum blocks or food residues can be sucked out of the patient's pharyngeal cavity more quickly, thereby buying time for rescue.
[0032] Embodiment 2
[0033] like Figure 2-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a new type of sputum suction tube joint for patient tracheal intubation, the head end portion 3 is an elastic cylindrical structure, the inner wall of the head end portion 3 is fixedly installed with a support ring 6, the side wall of the support ring 6 is welded with an expansion piece 8 extending toward the opening of the head end portion 3, the expansion piece 8 is inserted into the head end portion 3, and the inner side of the end of the expansion piece 8 close to the support ring 6 is integrally formed with an expansion protrusion 9, the end face of the expansion protrusion 9 away from the support ring 6 is an arc end, and the interior of the head end portion 3 is also movably provided with a The support rod 11 slides axially along the head end portion 3, and the edge of the support rod 11 corresponding to the expansion piece 8 protrudes outward and fits with the expansion piece 8. Then, when the support rod 11 slides toward the support ring 6 in the head end portion 3, the support rod 11 first slides along the expansion piece 8 and then fits with the expansion protrusion 9, pushing the expansion protrusion 9 outward, and then drives the expansion piece 8 to prop up the head end portion 3 to form a trumpet shape. When the support rod 11 is separated from the expansion protrusion 9 and contacts the expansion piece 8, the expansion piece 8 retracts under the action of its own elastic force, drives the head end portion 3 to shrink, and returns to the cylindrical structure, which is convenient for moving in the trachea.
[0034] The expansion pieces 8 are evenly spaced and circumferentially surround the side wall of the support ring 6 .
[0035] A limiting block 12 is fixedly installed at one end of the support rod 11 close to the expansion piece 8, and a limiting groove 13 is provided on the expansion piece 8 and the expansion protrusion 9 at a position corresponding to the limiting block 12. The limiting block 12 can slide in the limiting groove 13, thereby fixing the relationship between the support rod 11, the expansion piece 8 and the expansion protrusion 9, and preventing the support rod 11 from separating from the expansion piece 8 and the expansion protrusion 9.
[0036] A connecting rope 10 is also fixedly installed in the middle of the support rod 11 . The connecting rope 10 extends toward the tube body 1 and passes through the tube body 1 . Medical staff can directly pull the connecting rope 10 from the outside to control the position of the support rod 11 in the head end portion 3 .
[0037] A support frame 7 is also fixedly mounted in the middle of the support ring 6 . The support frame 7 is a cross-shaped structure to increase the structural stability of the support ring 6 .
[0038] A control ring 14 is sleeved on the tube body 1 at the position where the connecting rope 10 passes through the wall of the tube body 1. The control ring 14 is fixedly connected to the connecting rope 10. The control ring 14 is sealed to the tube body 1 and can slide on the outer wall of the tube body 1. The pulling of the connecting rope 10 is controlled by sliding the control ring 14.
[0039] In this embodiment, the use environment of the suction tube is first determined. If temporary expansion is required to increase the suction area, the control ring 14 is slid backward and the connecting rope 10 is partially pulled out. At this time, the support rod 11 slides toward the expansion protrusion 9 in the expansion piece 8. When the support rod 11 slides between the expansion protrusions 9, the expansion piece 8 is propped up, so that the head end 3 is deformed into a trumpet-shaped structure to increase the suction area. If it is necessary to move in the trachea, the control ring 14 is loosened, so that the support rod 11 is squeezed out between the expansion protrusions 9 under the action of elastic force, and contacts with the expansion piece 8, so that the head end 3 is reset to a cylindrical structure for easy movement.
[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
