FIG5 is an exploded schematic diagram of an oxygen mask system according to an embodiment of the present invention, and FIG6 is a structural schematic diagram of an oxygen mask system according to an embodiment of the present invention. Please refer to FIG2, FIG5 and FIG6 simultaneously, the oxygen mask system 100 includes an oxygen mask 1, a connecting tube assembly 2 and an air storage bag assembly 6. The oxygen mask 1 includes a mask body 10, two one-way valves 14 and a mask interface 12, the two one-way valves 14 are respectively arranged on both sides of the upper end of the mask body 10, and the mask interface 12 is arranged at the middle protrusion of the mask body 10; in one embodiment, the oxygen mask 1 is, for example, a high oxygen concentration mask or a non-rebreathing mask, but is not limited thereto. The connecting tube assembly 2 includes a coil structure 3, a main tube body 32, a drug delivery assembly 40, a ring sheet 324, a piston structure 50, and a side tube body 34; the structure of the connecting tube assembly 2 has been described above, so the relevant description is omitted here. The air bag assembly 6 includes an air bag 62 and an air bag connector 64. The air bag 62 stores gas, such as oxygen. One end of the air bag connector 64 is inserted into the side tube opening 341 of the side tube body 34 of the connecting tube assembly 2, and the other end is connected to the air bag 62.

In one embodiment, the oxygen mask system further includes a spray medicine cup set 7, the spray medicine cup set 7 includes a cup cover 72 and a spray medicine cup 74, the cup cover 72 is covered on the spray medicine cup 74, and a cup cover tube 721 is provided at the top of the cup cover 72. As shown in the subsequent FIG. 7, the cup cover tube 721 is suitable for inserting into the lower port 323 of the main body 32 and pushing through the medicine tray 56 to move the piston structure 50 upward.

FIG7 and FIG8 are cross-sectional schematic diagrams of different implementation states of the oxygen mask system of the first embodiment of the present invention. As shown in FIG7 and FIG8, when the cup cover tube 721 of the spray medicine cup set 7 is not inserted into the lower port 323, the piston structure 50 penetrating the ring sheet 324 has a maximum width R3 greater than the inner diameter R2 of the ring sheet 324, so that the cone head 52 is naturally placed above the ring sheet 324 due to gravity, and because the diameter R4 of the medicine tray is less than or equal to (the difference is less than 1.1 mm) the inner diameter R1 of the main body 32, the piston structure 50 is not easy to tilt with the shaking of the connecting pipe assembly 2. When the cup cover tube 721 is inserted into the lower port 323, the cup cover tube 721 contacts the bottom of the medicine tray 56 and pushes the medicine tray 56 upward, causing the piston structure 50 to move upward until the medicine tray 56 stops at the ring 324 because the diameter R4 of the medicine tray is larger than the inner diameter R2, and the cup cover tube 721 completely enters the main tube 32.

When the oxygen mask system 100 is used, the connecting tube assembly 2 is used to connect the oxygen mask 1 and the air storage bag assembly 6. The mask interface 12 in the middle of the mask body 10 of the oxygen mask 1 is used to accommodate the upper connection portion 22 of the telescopic tube 20 or the upper connection portion 22 of the connector 28, and provide a space for gas to flow when the patient breathes; the mask body 10 covers the patient's mouth and nose, and the one-way valve 14 at the upper end of the mask body 10 is designed to prevent gas backflow. The air bag 62 is connected to the side tube opening 341 of the side tube body 34 via the air bag connector 64, wherein the air bag 62 is filled with gas (e.g., oxygen). As the patient inhales, the gas in the air bag 62 enters the side tube body 34 and enters the main tube body 32 through the tube wall opening 342. In one embodiment, a one-way valve may also be provided in the air bag connector 64.

Continuing with the above description, when the spray cup set 7 is connected to the lower port 323 of the main body 32 according to the needs of the patient, the amount of spray medicine inhaled by the patient can be stabilized by stretching the telescopic portion 24 of the telescopic tube 20 (shown in FIG. 6 ). Specifically, the spray medicine delivered by the spray cup set 7 passes through the medicine port 57 and the ring sheet 324 and moves upward along the conical head 52. The gas provided by the air storage bag 62 and the spray medicine are gathered at the intersection of the main body 32 and the side tube body 34, and enter the mask along the snake tube structure 3, so that the patient can inhale it into the body. When the patient exhales carbon dioxide, the carbon dioxide will leave the range covered by the mask body 10 through the one-way valve 14. The one-way valve 14 can prevent carbon dioxide from flowing back to the oxygen mask 1 and causing a decrease in oxygen concentration. In one embodiment, a one-way valve (not shown) can also be set in the connector 28 of the connecting pipe assembly 2 to prevent carbon dioxide from flowing back into the main pipe 32.

Fig. 9 is another application schematic diagram of the oxygen mask system of the first embodiment of the present invention. As shown in Fig. 9, the oxygen mask system 100A further includes a spray canister 8, which is suitable for being inserted into the drug inlet 441 (shown in Fig. 3) of the drug administration assembly 40, and as the spray canister 8 is pressed down, a spray agent is quantitatively sprayed for inhalation by the patient. When using the spray cup set 7 or the spray can 8, the telescopic portion 24 of the telescopic tube 20 can be extended (shown in FIG. 6 ) or shortened (shown in FIG. 9 ) according to the use requirements. The extended telescopic portion 24 can be used as an air storage chamber to stabilize the amount of spray medicine inhaled by the patient each time and avoid the spray medicine residue remaining in the connecting tube assembly 2, thereby causing the spray medicine to be wasted. In addition, the telescopic portion 24 can change the angle, such as being bent, to ensure that the spray cup set 7 remains vertical.

Based on the above, the connecting tube assembly of this invention connects the oxygen mask and the main tube body through the coil structure, and connects the main tube body and the air storage bag assembly through the side tube body. The main tube body can be connected to the spray cup or spray tank according to the use requirements, so that oxygen and spray agents are gathered in the main tube body, and then sent to the oxygen mask through the coil structure, so that the patient can receive spray therapy while undergoing high-concentration oxygen therapy. In addition, the retractable characteristics of the coil structure can allow the patient to stably absorb the spray agent, avoiding the spray agent residue remaining in the connecting tube assembly, affecting the effect of the treatment and the waste of the spray agent. In addition, the telescopic part can change its angle, such as bending, to ensure that the spray cup assembly can remain vertical.

Although this creation has been disclosed as above by way of embodiments, it is not intended to limit this creation. People with ordinary knowledge in the technical field to which this creation belongs can make some changes and embellishments without departing from the spirit and scope of this creation.
