Description

Technical Field

[0001] This utility model relates to the field of oxygen supply systems for medical ambulances, specifically to an H-type oxygen pipeline system for ambulances. Background Technology

[0002] Currently, ambulances are generally equipped with oxygen pipeline systems, which often employ a dual-cylinder system to ensure rapid switching to a spare cylinder when the oxygen cylinder runs out. However, existing dual-cylinder switching systems are mostly single parallel or series structures, which have problems such as untimely switching, unstable pressure, and limited installation space. Under prolonged, high-flow oxygen supply or when equipment (such as ventilators and ECMO) is running simultaneously, oxygen supply interruptions or pressure fluctuations can easily occur, affecting patient safety.

[0003] However, under different usage conditions, the oxygen output demand of the dual oxygen output lines may vary. Therefore, the oxygen distribution of the dual oxygen output lines needs to be allocated according to different usage conditions. For example, under normal usage conditions, the oxygen distribution of the two oxygen output lines is the same. When the dual oxygen output lines need to output oxygen simultaneously and rely solely on the other oxygen cylinder when one oxygen cylinder is depleted, the oxygen output demand of the main oxygen supply line is often higher than that of the other oxygen output line. In this case, the oxygen distribution of the two oxygen output lines is different. However, the existing oxygen pipeline system cannot control the oxygen distribution of the dual oxygen output lines differently, thus failing to meet their corresponding usage requirements.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] like Figure 1-5As shown, an H-type oxygen pipeline system for an ambulance includes a gas distribution device 50, a first oxygen supply device 10, a first oxygen output pipeline 20, a second oxygen supply device 30, and a second oxygen output pipeline 40. The gas distribution device 50 includes a gas distribution section 51 and a gas volume control device 60. The gas distribution section 51 is provided with a gas distribution channel 511, a first air inlet structure 512, a first air outlet structure 513, a second air inlet structure 514, and a second air outlet structure 515. The first air inlet structure 512 and the first air outlet structure 513 are respectively connected to one end of the gas distribution channel 511, and the second air inlet structure 514 and the second air outlet structure 515 are respectively connected to the other end of the gas distribution channel 511. The first oxygen supply device 10 is connected to the first air inlet structure 512, and the first oxygen output pipeline 20 is connected to the first air outlet structure 513. The oxygen supply device 30 is connected to the second air intake structure 514, and the second oxygen output pipeline 40 is connected to the second air outlet structure 515. The gas volume control device 60 includes a gas control body 61, a gas control core 62, and a drive device 63. The gas control body 61 is disposed in the gas distribution chamber 511, and the gas control body 61 is provided with a gas control chamber 611. Both ends of the gas control chamber 611 are provided with a ventilation connecting chamber 612. The gas control core 62 is installed in the gas control body 61 and is used to cover the ventilation connecting chamber 612. The drive device 63 is used to selectively drive the gas control core 62 to a first position, a second position, and a third position. When the gas control core 62 is in the first position, the ventilation connecting chamber 612 is closed. When the gas control core 62 is in the third position, the open area of ​​the ventilation connecting chamber 612 is larger than the open area of ​​the ventilation connecting chamber 612 when the gas control core 62 is in the second position.

[0026] In use, by opening the first air intake structure 512, the first air outlet structure 513, the second air intake structure 514, and the second air outlet structure 515, air is supplied by the first oxygen supply device 10 and the second oxygen supply device 30. At this time, the oxygen supplied by the first oxygen supply device 10 and the second oxygen supply device 30 flows to the gas distributor 51, so that the oxygen can flow through the gas distributor 51 to the first oxygen output pipeline 20 and the second oxygen output pipeline 40, and be output through the first oxygen output pipeline 20 and the second oxygen output pipeline 40. During this process, the gas control core 62 is driven to move to the first position by the drive device 63. At this time, the gas control core 62 closes the ventilation communication cavity 612, so that the oxygen supplied by the first oxygen supply device 10 and the second oxygen supply device 30 can be supplied to the first oxygen output pipeline 20 and the second oxygen output pipeline 40 respectively.

[0027] When the second oxygen supply device 30 is depleted and only the first oxygen supply device 10 supplies gas, and the first air inlet structure 512, the first air outlet structure 513, and the second air outlet structure 515 are open, the oxygen supplied by the first oxygen supply device 10 can flow into the gas control cavity 611 through the first air inlet structure 512, flow to the first oxygen output pipeline 20 through the first air outlet structure 513, and flow to the second oxygen output pipeline 40 through the gas control cavity 611, the gas volume control device 60, and the second air outlet structure 515. During this process, the gas control core 62 can be driven to the second position or the third position according to the usage requirements. By reducing or increasing the open area of ​​the ventilation cavity 612, the amount of oxygen flowing to the second oxygen output pipeline 40 can be reduced or increased, thereby realizing different control of the oxygen distribution of the first oxygen output pipeline 20 and the second oxygen output pipeline 40.

[0028] In use, the second oxygen supply device 30 can be used alone to open the second air inlet structure 514 and the first air outlet structure 513, supplying oxygen to the first oxygen output pipeline 20 independently. Alternatively, the first oxygen supply device 10 can be used alone to open the first air inlet structure 512 and the second air outlet structure 515, supplying oxygen to the second oxygen output pipeline 40 independently. Other gas supply configurations can be implemented depending on the usage requirements.

[0029] This utility model provides an H-type oxygen pipeline system for ambulances. Based on the existing gas distribution device 50, first oxygen supply device 10, first oxygen output pipeline 20, second oxygen supply device 30, and second oxygen output pipeline 40, the gas distribution device 50 combines a gas distribution 51 and a gas volume control device 60. Airflow is centrally managed through a gas distribution chamber 511, with the gas control unit 61 housed within the chamber 511. This reduces pipeline complexity, making the structure more compact. It supports simultaneous or independent oxygen supply from both the first oxygen supply device 10 and the second oxygen supply device 30, providing greater flexibility. Furthermore, by modifying the first air intake structure… 512, the opening and closing operations of the first air outlet structure 513, the second air inlet structure 514, and the second air outlet structure 515 enable rapid switching between the dual oxygen supply of the first oxygen output pipeline 20 and the second oxygen output pipeline 40, while ensuring pressure balance and redundancy, thus improving the safety and reliability of the operation. Moreover, by driving the gas control core 62 to move to the first position, the second position, or the third position through the drive device 63, the amount of oxygen flowing to the first oxygen output pipeline 20 and the second oxygen output pipeline 40 can be adjusted according to the usage conditions, realizing different control of the oxygen distribution of the first oxygen output pipeline 20 and the second oxygen output pipeline 40, which can meet more different usage needs.

[0030] The pneumatic control core 62 includes a central body 621, a first cover 622, and a second cover 623. The first cover 622 and the second cover 623 are respectively placed on both sides of the central body 621. The driving device 63 is connected to the central body 621. The first cover 622 and the second cover 623 are respectively used to cover the two ventilation communication cavities 612. By adopting the above structure, the first cover 622 and the second cover 623 can be used to cover the two ventilation communication cavities 612 respectively, which is convenient for manufacturing.

[0031] The first cover 622 extends in an arc shape and is connected to the central body 621 via a first connecting arm 624. The second cover 623 extends in an arc shape and is connected to the central body 621 via a second connecting arm 625. Specifically, both the first cover 622 and the second cover 623 include a frame, a cover body movably mounted on the frame, and an elastic element disposed between the frame and the cover body. When the ventilation cavity 612 is completely closed, the elastic force provided by the elastic element ensures the airtightness of the cover body covering the ventilation cavity 612.

[0032] When the gas control core 62 is in the third position, the first cover 622 and the second cover 623 are both offset from the corresponding ventilation cavity 612, so that the ventilation cavity 612 is fully open, which can maximize the amount of oxygen flowing through the ventilation cavity 612.

[0033] The ventilation cavity 612 has a mating wall 71. When the air control core 62 is in the second position, the first cover 622 and the second cover 623 both cover at least a portion of the corresponding ventilation cavity 612, and the first cover 622 and the second cover 623 form a vent with the mating wall 71 of the corresponding ventilation cavity 612 at intervals. In this embodiment, when the air control core 62 is in the second position, the first cover 622 and the second cover 623 both cover half of the corresponding ventilation cavity 612.

[0034] The driving device 63 includes a drive motor. In this embodiment, the central body 621 is rotatably mounted in the pneumatic control cavity 611 and is circular in shape. A rotating shaft extending from the gas separator 51 is provided on the central body 621. The rotating shaft is sealed to the pneumatic control body 61. The output shaft of the drive motor is connected to the rotating shaft. By adopting the above structure, it is convenient to drive the pneumatic control core 62 to rotate to the first position, the second position, and the third position, and it is convenient to install.

[0035] The first air intake structure 512, the first air outlet structure 513, the second air intake structure 514, and the second air outlet structure 515 all include a ventilation chamber 80 and a valve core 81; the valve core 81 is used to control the opening and closing of the ventilation chamber 80. In this embodiment, by rotating the valve core 81 to be parallel to the ventilation chamber 80, the ventilation chamber 80 can be opened for flow; by rotating the valve core 81 to be perpendicular to the ventilation chamber 80, the ventilation chamber 80 can be shut off. The first oxygen supply device 10 is connected to the first air intake structure 512 through a first oxygen input pipeline 90; a first pressure reducing valve 91 is provided on the first oxygen input pipeline 90. In use, the oxygen supplied by the first oxygen supply device 10 can be depressurized by the first pressure reducing valve 91 when flowing through the first oxygen input pipeline 90, and then flows through the first oxygen input pipeline 90 to the first air intake structure 512.

[0036] The second oxygen supply device 30 is connected to the second air intake structure 514 via the second oxygen input pipeline 100; a second pressure reducing valve 101 is provided on the second oxygen input pipeline 100. In use, the oxygen supplied by the second oxygen supply device 30 is depressurized by the second pressure reducing valve 101 when it flows through the second oxygen input pipeline 100, and then flows through the second oxygen input pipeline 100 to the second air intake structure 514.

[0037] In the actual design, the first oxygen output pipeline 20, the second oxygen output pipeline 40, the gas separator 50, the first oxygen input pipeline 90, and the second oxygen input pipeline 100 form an H-shape.

[0038] The end of the first oxygen output pipeline 20 furthest from the gas separator 51 is connected to a first oxygen terminal 102, and the end of the second oxygen output pipeline 40 furthest from the gas separator 51 is connected to a second oxygen terminal 103. The first oxygen terminal 102 and the second oxygen terminal 103 may include quick-connect interfaces and threaded interfaces, etc.
