Technical Field

[0001] This utility model relates to the field of oxygen cylinder technology, and in particular to an oxygen cylinder device that can be used by multiple people. Background Technology

[0002] Oxygen cylinders are high-pressure containers used for storing and transporting oxygen. They are generally made of alloy structural steel through hot stamping and pressing. Oxygen cylinders are usually cylindrical. The main production process involves filling the interior of the oxygen cylinder with compressed liquefied oxygen. Because the steel cylinder has a certain structural strength, it can hold a large amount of liquid oxygen.

[0003] A search revealed Chinese patent CN213374513U, which discloses an oxygen cylinder comprising: an oxygen cylinder body; a humidifier connected to the outlet of the oxygen cylinder body; the outlet of the humidifier being connected to an oxygen mask via an oxygen tube; a regulating valve with a pressure gauge being provided between the oxygen cylinder body and the humidifier; and an oxygen cylinder quick-connect fitting, which is a snap-on strap quickly attached to the oxygen cylinder body, with a connector mounted on the snap-on strap, wherein the connector is a C-type connector or an annular connector; a connecting groove or connecting hole corresponding to the snap-on strap is provided on the C-type connector or annular connector, and the snap-on strap is installed in the connecting groove or connecting hole; and an auxiliary component is also fixedly provided on the connector, which is used to organize and store the oxygen tube or to secure it to the required device.

[0004] However, in this patent, the oxygen cylinder can only deliver oxygen to one patient through an oxygen tube and an oxygen mask. In the case of major disaster relief, medical teams need to deliver oxygen to a large number of patients, but the number of oxygen cylinders carried by the medical teams is generally insufficient to meet the needs of a large number of patients, thereby reducing the effectiveness of treatment.

[0005] Therefore, we have made improvements to this and proposed an oxygen cylinder device that can be used by multiple people. Utility Model Content

[0006] The purpose of this invention is to address the problem that the number of oxygen cylinders in the existing technology is generally insufficient to meet the needs of a large number of patients, thereby reducing the effectiveness of treatment. Therefore, this invention proposes an oxygen cylinder device that can be used by multiple people.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An oxygen cylinder device usable by multiple people includes an oxygen storage cylinder. An exhaust pipe is fixedly inserted through one side of the oxygen storage cylinder. An oxygen delivery unit is detachably connected to the end of the exhaust pipe away from the oxygen storage cylinder. The oxygen delivery unit includes three branch pipes and one main pipe. All three branch pipes are connected to the main pipe. The ends of the branch pipes away from the main pipe are connected to oxygen masks. A valve is fixedly fitted on the outer periphery of the exhaust pipe. An air valve and a pressure reducing valve are fixedly fitted on the outer periphery of the branch pipes. An indicator is provided above the oxygen storage cylinder.

[0009] As a preferred technical solution of this application, the indicating part includes a top shell fixedly connected to the top of the oxygen storage cylinder, a piston slidably connected to the upper half of the oxygen storage cylinder, a sliding column fixedly connected to the top of the piston, the sliding column slidingly passing through the top wall of the oxygen storage cylinder and extending into the top shell, a sliding plate fixedly sleeved on the outer surface of the sliding column, the sliding plate slidably connected to the top shell, and a plurality of springs fixedly connected between the sliding plate and the top of the oxygen storage cylinder, and an indicating unit provided above the sliding plate.

[0010] As a preferred technical solution of this application, the indicating unit includes a rack fixedly connected to the upper half of one side of the sliding column, a rotating rod rotatably connected to the upper half of the top shell, a gear fixedly sleeved on the outer circumferential surface of the rotating rod, the rack meshing with the gear, the rotating rod extending to the outside of the top shell, and a scale fixedly connected to the outer wall of the top shell, and an indicating rod fixedly connected to the outer circumferential surface of the rotating rod at the outside of the top shell.

[0011] As a preferred technical solution of this application, when the oxygen content in the oxygen storage cylinder is sufficient for three people to use at the same time, the top surface of the sliding column is in contact with the inner top wall of the top shell, the spring is in an extended state, the sliding plate is located below the gear, and the indicator rod points to the leftmost position of the dial.

[0012] As a preferred technical solution of this application, the exhaust pipe is inserted into the main pipe, and the exhaust pipe and the main pipe are threadedly connected.

[0013] As a preferred technical solution of this application, an air inlet pipe is fixedly installed on one side of the oxygen storage cylinder, and a one-way valve is fixedly sleeved on the outer periphery of the air inlet pipe.

[0014] As a preferred technical solution of this application, the main pipe and the three branch pipes are all made of flexible hoses.

[0017] As a preferred technical solution of this application, a transparent sealing cover is fixedly connected to the front side of the top shell, and the indicator rod, dial and switch are all located inside the transparent sealing cover.

[0018] Compared with the prior art, this utility model provides an oxygen cylinder device that can be used by multiple people, and has the following beneficial effects:

[0019] 1.

[0020] 2. This multi-person oxygen cylinder device, through the cooperation of a piston, rack and pinion, gear, spring, indicator rod and dial, when the pressure inside the oxygen cylinder is sufficient, the indicator rod points to the position of 3 people on the dial.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Reference Figure 1-4 An oxygen cylinder device usable by multiple people includes an oxygen storage cylinder 1. An exhaust pipe 2 is fixedly installed on one side of the oxygen storage cylinder 1 and communicates with the oxygen storage cylinder 1. An oxygen delivery unit 3 is detachably connected to the end of the exhaust pipe 2 away from the oxygen storage cylinder 1. The oxygen delivery unit 3 includes three branch pipes 31 and one main pipe 32. The main pipe 32 and the three branch pipes 31 are all made of flexible hoses. The three branch pipes 31 are all connected to the main pipe 32. The end of the branch pipe 31 away from the main pipe 32 is connected to an oxygen mask. A valve 4 is fixedly sleeved on the outer periphery of the exhaust pipe 2. An air valve 33 and a pressure reducing valve 34 are fixedly sleeved on the outer periphery of the branch pipes 31. An indicator 5 is provided above the oxygen storage cylinder 1.

[0033] When oxygen is not being administered, valve 4 and air valve 33 are both closed. When oxygen is needed, valve 4 and the corresponding number of air valves 33 are opened. For example, if two people are receiving oxygen, two air valves 33 are opened, allowing oxygen from the oxygen reservoir 1 to enter the corresponding two branch pipes 31. The patient inhales the oxygen from the two branch pipes 31 through an oxygen mask. The pressure reducing valve 34 reduces the high-pressure oxygen in the oxygen reservoir 1 to a pressure suitable for the patient's inhalation.

[0034] like Figure 3-4As shown, in a preferred embodiment, based on the above method, the indicator 5 further includes a top shell 51 fixedly connected to the top of the oxygen storage cylinder 1, a piston 52 slidably connected to the upper half of the oxygen storage cylinder 1, a sliding column 53 fixedly connected to the top of the piston 52, the sliding column 53 slidingly passing through the top wall of the oxygen storage cylinder 1 and extending into the top shell 51, a sliding plate 54 fixedly sleeved on the outer surface of the sliding column 53, the sliding plate 54 slidably connected to the top shell 51, and a plurality of springs 55 fixedly connected between the sliding plate 54 and the top of the oxygen storage cylinder 1, and an indicator unit 56 provided above the sliding plate 54.

[0035] The outer wall of piston 52 is fully fitted with the inner wall of oxygen storage cylinder 1, preventing oxygen from passing through piston 52. When the gas pressure inside oxygen storage cylinder 1 decreases, the thrust of oxygen on piston 52 also decreases.

[0036] like Figure 3-4 As shown, in a preferred embodiment, based on the above method, the indicating unit 56 further includes a rack 561 fixedly connected to the upper half of one side of the sliding column 53, a rotating rod 562 rotatably connected to the upper half of the top shell 51, a gear 563 fixedly sleeved on the outer circumferential surface of the rotating rod 562, the rack 561 meshing with the gear 563, a portion of the rotating rod 562 extending to the outside of the top shell 51, and a scale 564 fixedly connected to the outer wall of the top shell 51. An indicating rod 565 is fixedly connected to the outer circumferential surface of the rotating rod 562 at the outside of the top shell 51.

[0037] The dial 564 is marked with “1 person”, “2 people” and “3 people”, and the indicator rod 565 points to different positions on the dial 564, indicating that the oxygen storage cylinder 1 can also enable several people to breathe oxygen at the same time.

[0038] When the oxygen content in the oxygen storage cylinder 1 is sufficient for three people to use at the same time, the top surface of the sliding column 53 is in contact with the inner top wall of the top shell 51, the spring 55 is in the extended state, and the sliding plate 54 is located below the gear 563. The indicator rod 565 points to the leftmost position of the dial 564 (3 people). At this time, the oxygen storage cylinder 1 can be used by three people to inhale oxygen at the same time.

[0039] When the air pressure inside the oxygen storage cylinder 1 drops to a certain level, it is no longer sufficient for three people to inhale oxygen at the same time. At this point, the thrust of the oxygen on the piston 52 decreases, and the piston 52 moves downward under the restoring force of the spring 55. The piston 52 drives the sliding column 53 and the rack 561 to move. The rack 561 drives the gear 563 to rotate. The gear 563 drives the rotating rod 562 and the indicator rod 565 to rotate. The indicator rod 565 rotates to the right, pointing to the "2 people" or "1 person" position on the dial 564, so that medical staff can intuitively observe how many people can use the oxygen storage cylinder 1 at the same time.

[0040] like Figure 2As shown, in a preferred embodiment, based on the above method, the exhaust pipe 2 is further inserted into the main pipe 32, and the exhaust pipe 2 and the main pipe 32 are threadedly connected. When the device is not in use, the main pipe 32 can be removed to facilitate the transport of the oxygen storage cylinder 1, or to clean the main pipe 32 and the branch pipe 31.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, an air inlet pipe 6 is fixedly inserted through one side of the oxygen storage cylinder 1, and a one-way valve 7 is fixedly sleeved on the outer periphery of the air inlet pipe 6. The one-way valve 7 can only allow oxygen to enter the oxygen storage cylinder 1 from outside the air inlet pipe 6 through the air inlet pipe 6. When the oxygen content in the oxygen storage cylinder 1 is insufficient, oxygen is added to the oxygen storage cylinder 1 through the air inlet pipe 6.

[0042] like Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, an L-shaped support plate is fixedly connected to the side wall of the top shell 51. A switch 8 is fixedly connected to the end of the support plate away from the top shell 51. The switch 8 is located to the right of the dial 564, and the switch 8 is electrically connected to the valve 4. The valve 4 is a manual-automatic integrated valve, which can be opened and closed manually or controlled by the switch 8.

[0043] When the oxygen content in oxygen storage cylinder 1 drops to a dangerous level, piston 52 moves to the lowest position, indicator rod 565 rotates to the right and presses against switch 8. Switch 8 controls valve 4 to close, thereby automatically stopping oxygen supply and preventing dust from entering due to excessively low pressure in oxygen storage cylinder 1, thus ensuring safety.

[0044] Specifically, when using this multi-person oxygen cylinder device: open valve 4 and the corresponding number of air valves 33, so that multiple patients can simultaneously inhale oxygen through various oxygen masks.

[0045] When the air pressure inside the oxygen storage cylinder 1 drops to a level where it is less than three people can inhale oxygen at the same time, the thrust of the oxygen on the piston 52 decreases. Under the restoring force of the spring 55, the piston 52 moves downward. The piston 52 drives the sliding column 53 and the rack 561 to move. The rack 561 drives the gear 563 to rotate. The gear 563 drives the rotating rod 562 and the indicator rod 565 to rotate. The indicator rod 565 rotates to the right, pointing to the "2 people" or "1 person" position on the scale 564, so that medical staff can intuitively observe how many people can use the oxygen storage cylinder 1 at the same time.

[0046] When the oxygen content in oxygen storage cylinder 1 drops to a dangerous level, the indicator lever 565 is turned to the right and pressed against switch 8. Switch 8 controls valve 4 to close, thereby automatically stopping the oxygen supply and preventing dust from entering due to excessively low pressure in oxygen storage cylinder 1, thus ensuring safety.

[0047] Example 2:

[0048] Reference Figure 5-6 This embodiment includes all the components in embodiment 1. A transparent sealing cover 9 is fixedly connected to the front side of the top shell 51. The indicator rod 565, the dial 564 and the switch 8 are all located inside the transparent sealing cover 9. The transparent sealing cover 9 is made of transparent glass material, which can not affect the medical staff's observation of the dial 564, and can also prevent the patient from accidentally touching the switch 8 and causing the valve 4 to close.

[0049] A base 10 is provided below the oxygen storage cylinder 1. The base 10 includes a top plate and a bottom plate. A placement shell is fixedly inserted through the bottom of the top plate. The lower half of the oxygen storage cylinder is placed inside the placement shell. Several shock absorbers are installed between the bottom and top of the top plate to reduce the vibration amplitude of the oxygen storage cylinder 1 during transportation and improve safety.

[0050] Several rollers are rotatably connected to the bottom of the base plate, and a push plate is fixedly connected to one side of the base plate. The push plate and rollers facilitate the transfer of oxygen storage cylinder 1 by the staff. Two through holes are opened at the top of the top plate, and fire extinguishers are placed in the through holes for timely fire extinguishing in case of fire, which improves the fire resistance of oxygen storage cylinder 1.

[0051] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
