[0002] Oxygen bags are bags used to hold oxygen, primarily made from non-toxic, chemically harmless materials. They are lightweight, easy to carry, store, and operate, making them widely used in home healthcare, emergency medical services, pre-hospital emergency care, and patient transport.

[0003] Clinically, oxygen bags are used frequently in emergency departments, and patients need to carry oxygen bags when they go out for emergency treatment to meet their oxygen needs. Currently, the end of the portable oxygen bag connection tube cannot be tightly connected to the end of the patient's nasal cannula or mask oxygen inhalation tube, and it is easy to fall off, resulting in an interruption of oxygen supply. For patients who need continuous oxygen inhalation, this may cause a decrease in blood oxygen saturation, and then cause symptoms such as difficulty breathing, chest tightness, and palpitations, which may even be life-threatening in severe cases. In addition, once the oxygen supply line is reconnected after an interruption, improper operation or loose connection may cause oxygen leakage or insufficient oxygen supply. Therefore, an oxygen bag sealing joint is designed and produced here to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0023] Embodiment, this embodiment provides an oxygen bag sealing joint 1, comprising: a joint 1, the joint 1 is a hollow structure, the outer wall of the joint 1 is symmetrically provided with two air holes, one of the air hole outer opening side wall is fixedly connected to a rotating sleeve 22, and the rotating sleeve 22 is rotatably sleeved with a joint pipe 2, and the other air hole outer opening side wall is fixedly connected to a joint pipe 2 3. Figure 1 and Figure 5 As shown, a sealing treatment is performed at the connection between the rotating sleeve 22 and the side wall of the outer opening of the pore, for example, by applying glue, to avoid air leakage. The butt joint 2 can rotate with the axis of the rotating sleeve 22 as the rotation center. The butt joint 2 is connected to the end of the oxygen bag output tube, and can be glued to prevent the butt joint 2 from being separated from the end of the oxygen bag output tube. The butt joint 2 3 is used to connect an external pipeline (such as the oxygen supply tube of the oxygen mask). It is particularly noted that the side wall of the outer opening of the pore is the side wall of the pore opening located on the outer wall of the butt joint 1, and correspondingly, the side wall of the inner opening of the pore is the side wall of the pore opening located on the inner wall of the butt joint 1.

[0024] The seal comprises an adjusting rod 4 and two hemispherical sealing heads 42 fixedly sleeved on the outer wall of the end of the adjusting rod 4. A gap is left between the two sealing heads 42. An air guide chamber 41 is provided in the axial direction of the adjusting rod 4. The openings at both ends of the air guide chamber 41 are provided on the radial side walls of the adjusting rod 4 and are symmetrically distributed on both sides of a sealing head 42 close to the sleeve tube 1. The outer wall of the edge of the sealing head 42 slides and fits with the inner wall of the rubber tube 13. The specific process of adjusting the adjusting rod 4 along the axial direction of the rubber tube 13 is as follows: two connecting rods are symmetrically fixed on the inner wall of the air hole connecting the butt joint tube 2, a threaded sleeve 14 is fixed between the ends of the two connecting rods, and the adjusting rod 4 is threadedly connected to the threaded sleeve 14. At the same time, a guide rod 21 is fixed on the inner radial side wall of the butt joint tube 2. The guide rod 21 has a rectangular guide portion extending along the axial direction of the butt joint tube 2. A rectangular groove 45 is provided on the end of the adjusting rod 4 facing the guide rod 21 to slide and plug into the rectangular guide portion. As shown Figure 2 、 Figure 3 and Figure 4 As shown, due to the sliding engagement of the rectangular groove 45 of the adjustment rod 4 with the rectangular guide portion of the guide rod 21, the adjustment rod 4 does not rotate around the rectangular guide portion. Therefore, by grasping the butt joint 1 (2) assembled with the end of the oxygen bag outlet tube with one hand and rotating the butt joint 1, the threaded sleeve 14 can rotate synchronously. The adjustment rod 4 and the threaded sleeve 14 can then be threaded together, and the adjustment rod 4 can be adjusted back and forth along the axis of the threaded sleeve 14, thereby driving the two sealing heads 42 to adjust their positions along the axis of the rubber tube 13. The two sealing heads 42 can then extend from the opening at the end of the rubber tube 13 and enter the interior space of the butt joint 1. Alternatively, they can be housed within the rubber tube 13, with the sidewalls of the sealing heads 42 slidingly engaging the inner wall of the rubber tube 13. The opening of the air guide chamber 41 between the two sealing heads 42 is sealed, blocking the passage of oxygen from the oxygen bag into the butt joint 1.

[0025] The end of the adjusting rod 4 can be adjusted along the axial direction of the rubber tube 13, and the opening of the air guide chamber 41 between the two sealing heads 42 can be adjusted to extend out of the opening of the end of the rubber tube 13 and enter the internal space of the docking joint 1, so that the opening of the air guide chamber 41 between the two sealing heads 42 can be exposed to the internal space of the docking joint 1. In this way, the space inside the oxygen bag and the internal space of the docking joint 1 are connected through the openings at both ends of the air guide chamber 41, and the oxygen in the oxygen bag enters the docking joint 1 through the air guide chamber 41, and the oxygen is then discharged from the external pipeline inserted in the docking pipe 3 to meet the patient's oxygen supply needs.

[0026] After the oxygen supply is completed, the regulating rod 4 is adjusted in the reverse direction to retract the opening of the air guide chamber 41 between the two sealing heads 42 into the rubber tube 13. The edge side walls of the two sealing heads 42 slide and fit with the inner wall of the rubber tube 13. In this way, the opening of the air guide chamber 41 between the two sealing heads 42 is in a closed state, and the opening of the air guide chamber 41 can be sealed in the rubber tube 13, thereby preventing the oxygen in the oxygen bag from leaking out and causing waste.

[0027] Because the rubber tube 13 has a certain degree of flexibility, when the sealing head 42 is adjusted to extend from the end opening of the rubber tube 13 into the interior space of the butt joint 1 and then retracted back into the rubber tube 13, the sidewall of the end of the sealing head 42 may abut against the sidewall of the end of the rubber tube 13, causing compression deformation at the end of the rubber tube 13. This in turn prevents the sealing head 42 from being smoothly retracted into the rubber tube 13, affecting the sealing of the oxygen bag passage. To this end, a plurality of elastic support rods 11 are fixed to the radial outer wall of the rubber tube 13. The ends of the elastic support rods 11 near the butt joint 2 are fixedly connected to the inner wall of the butt joint 1. The elastic support rods 11 can be made of PVC plastic, which has good elasticity. Furthermore, the ends of the elastic support rods 11 away from the guide rods 21 extend obliquely toward the side away from the center of the rubber tube 13, thereby expanding the end opening of the rubber tube 13 and increasing the inner diameter of the opening. Therefore, the multiple elastic support rods 11 stably support the rubber tube 13, ensuring that the rubber tube 13 is in a columnar structure. Then, when the sealing head 42 is reversely received into the interior of the rubber tube 13 along the opening at the end of the rubber tube 13, it can smoothly enter the rubber tube 13 through the enlarged opening and will not abut against the side wall of the end of the rubber tube 13.

[0028] Moreover, in order to prevent the external pipeline connected to the docking pipe 23 from falling off at will and causing the interruption of oxygen supply, at least two extension rods 43 are fixed to the outer wall of a sealing head 42 away from the docking pipe 2, and the end of the extension rod 43 is extended out of the end opening of the rubber tube 13 and fixed with an arc-shaped pressing block 44. The multiple arc-shaped pressing blocks 44 are distributed in an annular structure, and the side wall of the inner opening of the air hole connected to the docking pipe 23 is fixed with a rubber tube 212. The rubber tube 212 is a truncated cone-shaped hollow structure. The opening of the end of the rubber tube 212 away from the docking pipe 23 is smaller than the opening of the end close to the docking pipe 23. The inner diameter of the annular structure formed by the multiple arc-shaped pressing blocks 44 is larger than the outer diameter of the end of the rubber tube 212 away from the docking pipe 23, but at the same time smaller than the outer diameter of the end of the rubber tube 212 close to the docking pipe 23. Figure 2As shown, the external pipe is inserted into the docking pipe 2 3 and then into the rubber tube 2 12, achieving docking of the oxygen supply passage. As the sealing head 42 extends from the end opening of the rubber tube 13, it can drive the extension rod 43 to move synchronously, thereby pushing the multiple arc-shaped pressing blocks 44 along the outer wall of the rubber tube 2 12. At the same time, the pushing can squeeze the rubber tube 2 12 toward the tube center, thereby tightening the rubber tube 2 12 to the external connection, strengthening the fit between the inner wall of the rubber tube 2 12 and the outer wall of the external pipe, and preventing the external pipe from being easily detached.

[0029] Correspondingly, after the oxygen supply is completed, the sealing head 42 is stored in the rubber tube 1 13, and the extension rod 43 will drive the arc-shaped pressure block 44 to adjust away from the rubber tube 2 12, and the rubber tube 2 12 loses the squeezing force, thereby reducing the tightness of the external pipe end inserted into the rubber tube 2 12, making it easier to pull out.

[0030] Moreover, the opening at one end of the butt joint pipe 2 3 away from the air hole is a wide-mouth structure, which facilitates the external pipe to be smoothly inserted into the butt joint pipe 2 3 and into the rubber tube 2 12 through the wide-mouth structure.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
