[0001] The invention relates to the technical field of ventilators, in particular to a ventilator pipeline. Background Art

[0002] In the process of providing medical rescue, ventilators are often used to assist patients with additional breathing support. However, during this period, the pipe system inside the ventilator may produce a substance called condensed water. This condensed water accumulated in the pipes not only affects the delivery of oxygen, but also if it enters the patient's respiratory tract along the pipes, it may cause breathing difficulties and even endanger life.

[0003] At present, in the prior art, a water collecting cup is installed in the center of the air inlet end and the air outlet end of the breathing duct to collect condensed water in the duct.

[0004] However, during the actual use of the water collecting cup, the applicant discovered through multiple clinical observations that the water collecting cup usually inverts when it hits the ventilator's pipes, or when the patient is using the ventilator, especially when the road is bumpy on the emergency route, the ventilator's breathing pipe rotates a certain amount, and then the water collecting cup may suddenly invert, causing the condensed water discharged into the water collecting cup from the ventilator pipe to flow back into the pipe again. Therefore, after many experiments, the applicant invented a ventilator pipe of the present application in which condensed water is not likely to flow back during use. Summary of the invention

[0019] The technical scheme of the present invention is clearly and completely described below in conjunction with the specific embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1 like Figure 1 A ventilator pipeline, comprising an expiratory tube 1, an inspiratory tube 11 and a water collecting cup, wherein a Y-shaped joint 10 is provided on the top of the water collecting cup, and two branch pipes are provided on the top of the Y-shaped joint 10, wherein one end of the expiratory tube 1 and the inspiratory tube 11 are respectively connected to the two branch pipes of the Y-shaped joint 10, and the inspiratory tube 11 joint and the expiratory tube 1 joint are both connected to the ventilator, and a water collecting pipe 8 extending into the water collecting cup is provided at the bottom of the Y-shaped joint 10; The water collection cup includes a cup cover and an outer cup, the outer cup is threadedly connected to the cup cover, the cup cover is provided with a through hole and the through hole is fixedly connected to the outer wall of the Y-shaped joint 10, an inner cup 7 is provided on the outer wall of the water collection pipe 8 in the outer cup, a hinge mechanism is provided between the top of the inner cup 7 and the inner wall of the cup cover, the hinge mechanism includes a plurality of downwardly extending mounting rods 5 provided on both sides of the water collection pipe 8 on the bottom surface of the cup cover, the tops of the plurality of mounting rods 5 on the same side are hinged to the same hinge joint 9 on the bottom surface of the cup bottom, and the bottom ends thereof are respectively connected to the left and right sides of the inner cup 7, and the hinge joint 9 is provided with a stopper 4 for limiting the maximum rotation angle of the mounting rod 5. The hinge structure enables the inner cup 7 to make a certain horizontal rotation inside the outer cup, a gravity ball 6 is fixedly provided at the bottom of the inner cup 7, and the outer wall of the water collection pipe 8 is provided above the inner cup 7; The inner walls of the exhalation tube 1 and the inhalation tube 11 are both provided with thread grooves, and a drainage groove is provided between the upper and lower threads of the thread grooves. (Not shown in the figure) In specific implementation, the bottom of the water collecting pipe 8 is set to penetrate 0.5-2 cm into the cup mouth of the inner cup 7, and the inner wall of the cup mouth of the inner cup 7 is 1-3 cm away from the outer wall of the water collecting pipe 8.

[0021] The specific implementation method is: when this ventilator pipeline is in use, the exhalation tube 1 and the inhalation tube 11 are both connected to the ventilator. During specific implementation, the inhalation tube 11 can be connected to the humidifier and then to the ventilator. The other ends of the exhalation tube 1 and the inhalation tube 11 are connected to the two branches of the Y-type connector 10, and the outer cup of the water collecting cup is installed on the cup cover.

[0022] During use, when the user touches the breathing tube or there is a bump, the water collecting cup will be inverted to a certain extent. Since a hinge mechanism is provided between the top of the inner cup 7 and the cup cover, and a self-weight mechanism is provided at the bottom of the outer wall of the inner cup 7, the hinge mechanism can cause the inner cup 7 to rotate to a certain extent in the horizontal direction. At the same time, the combination of the self-weight mechanism can keep the inner cup 7 in a vertical downward setting, thereby preventing the condensed water in the inner cup 7 from flowing back into the water collecting pipe 8, preventing the condensed water from entering the breathing tube again and then entering the patient's respiratory tract, and avoiding the risk of causing difficulty in breathing and suffocation.

[0023] Embodiment 2 On the basis of the first embodiment, the applicant has made further improvements on how to avoid the water collection cup from being inverted, such as Figure 2 The applicant has modified the connection method between the exhalation tube and the inhalation tube 11 and the Y-type joint 10 in the first embodiment. Specifically, a rotating joint 2 is provided between the Y-type joint 10 and the exhalation tube 1 and the inhalation tube 11. A bearing member 12 is provided at the connecting end of the rotating joint 2 and the Y-type joint 10. The bearing member 12 is sealedly connected to the rotating joint 2 and the Y-type joint 10 so that the rotating joint 2 is rotatably connected to the Y-type joint 10.

[0024] The exhalation tube 1 and the inhalation tube 11 are sleeved at one end of the rotating joint 2, and a horizontal extension tube 3 is provided at the connecting end of the Y-type joint 10 and the rotating joint 2. The extension tube 3 is sleeved on the outer wall of the rotating joint 2, and a mounting groove is opened on the outer wall of the rotating joint 2. The bearing member 12 is arranged in the mounting groove so that the outer wall of the bearing member 12 is flush with the outer wall of the rotating joint 2.

[0025] After the above application, in actual use, if the expiratory tube 1 or the inhalation tube 11 of the ventilator is artificially collided, or the bumpy road causes the water collecting cup to be inverted, the water collecting cup will be inverted due to the dead weight of the inner cup 7 and the outer cup. The inner cup 7 is also provided with a gravity ball 6. Due to its own gravity, and because of the bearing connection method of the expiratory tube 1, the inhalation tube 11 and the rotating joint 2, the entire water collecting cup can always return to the outer cup vertically downward, and the water collecting cup will always be kept from being inverted, thereby avoiding the water in the water collecting cup from flowing back into the pipeline, and better preventing the water in the pipeline from being discharged into the cup in time. It has a strong applicable environment and a better safety effect.

[0026] Embodiment 3 On the basis of the second embodiment, the applicant took into consideration that some condensed water may have flowed from the inner cup 7 to the outer cup during the rotation process, and therefore the applicant set the distance between the outer wall of the inner cup 7 and the inner wall of the outer cup to 1-3 cm, and provided a downwardly extending annular baffle 13 at a distance of 0.5-1 cm from the bottom surface of the cup cover from the outer cup mouth, and the length of the baffle is 2-4 cm.

[0027] After the above application, when the condensed water overflowing from the inner cup 7 flows into the outer cup, even if rotation occurs, the condensed water will enter between the inner wall of the outer cup and the annular baffle 13 during rotation, thereby preventing the condensed water from flowing around in the cup and providing higher safety performance.

[0028] 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
