Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to an oxygen supply mask that is easy to connect. Background Technology

[0002] In modern medicine, oxygen masks are essential equipment, widely used in emergency care, intensive care, and the treatment of patients with respiratory diseases. They ensure patients receive sufficient oxygen and maintain stable vital signs. They are typically made of soft, face-conforming materials, such as silicone, which adapts to different facial contours to ensure a close fit and prevent oxygen leakage during use.

[0003] In existing technologies, the connection methods between oxygen inhalation tubes and oxygen tubing are often not convenient or secure enough. In practical use scenarios where frequent movement is required, an unstable connection may lead to interruption of oxygen delivery, which could pose a serious threat to the patient's life and health. Existing connection methods may lack an effective fixing mechanism and are prone to loosening due to external pulling, shaking, or other factors. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an oxygen supply mask that is easy to connect, and the oxygen tube and oxygen inhalation tube can be quickly positioned and adsorbed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An easily connectable oxygen supply mask includes: a mask body; an oxygen inhalation tube installed on the mask body for supplying oxygen to the mask body; an oxygen tube installed on the oxygen inhalation tube for supplying oxygen to the oxygen inhalation tube; a first connecting part installed on the oxygen inhalation tube and the oxygen tube, configured to fix the oxygen tube and the oxygen inhalation tube to each other when the oxygen tube is inserted into the oxygen inhalation tube; and a second connecting part installed on the oxygen inhalation tube and the oxygen tube, configured to further strengthen the fixation after the first connecting part fixes the oxygen tube and the oxygen inhalation tube.

[0024] The following is a detailed description of an easily connectable oxygen supply mask provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies. The accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0025] Example 1: As Figures 1 to 6 As shown, an easily connectable oxygen supply mask includes: a mask body 1; an oxygen inhalation tube 2, mounted on the mask body 1, for supplying oxygen to the mask body 1; an oxygen tube 3, mounted on the oxygen inhalation tube 2, for supplying oxygen to the oxygen inhalation tube 2; a first connecting part, mounted on the oxygen inhalation tube 2 and the oxygen tube 3, configured to fix the oxygen tube 3 and the oxygen inhalation tube 2 together when the oxygen tube 3 is inserted into the oxygen inhalation tube 2; and a second connecting part, mounted on the oxygen inhalation tube 2 and the oxygen tube 3, configured to further strengthen the fixation after the first connecting part fixes the oxygen tube 3 and the oxygen inhalation tube 2.

[0026] like Figures 4 to 6As shown, the first connecting part includes: a connecting ring 4, installed on one side of the oxygen tube 2; a first magnetic connector 5, installed in the connecting ring 4, located on one side of the oxygen tube 2; and a second magnetic connector 6, installed on one side of the oxygen tube 3, configured to magnetically connect the first magnetic connector 5 and the second magnetic connector 6 when the oxygen tube 3 and the oxygen tube 2 are close to each other.

[0027] like Figures 4 to 6 As shown, the first connecting part further includes: a fixing ring 7, installed on the oxygen tube 3; multiple sets of fixing blocks 8, evenly installed on the outer wall of the oxygen tube 3, configured such that multiple sets of fixing blocks 8 are installed between the fixing ring 7 and the second magnetic connector, with a gap between the multiple sets of fixing blocks 8 and the fixing ring 7; multiple sets of fixing grooves 9, evenly opened on the connecting ring 4, configured such that when the oxygen tube 3 is inserted into the connecting ring 4 of the oxygen inhalation tube 2, each set of fixing blocks 8 is inserted into a set of fixing grooves 9; and multiple sets of locking block 12 assemblies, with a set of locking block 12 assemblies installed in each set of fixing grooves 9, configured such that when the oxygen tube 3 is inserted into the connecting ring 4 of the oxygen inhalation tube 2, the locking block 12 assemblies are inserted into the gap between the fixing block 8 and the fixing ring 7.

[0028] like Figures 4 to 6 As shown, the locking block 12 assembly includes: a groove 10 formed on the connecting ring 4, the groove 10 communicating with the fixing groove 9; an elastic element 11 installed in the groove 10; a locking block 12 installed on the elastic element 11, configured such that when the oxygen tube 3 is inserted into the connecting ring 4 of the oxygen inhalation tube 2, the fixing block 8 squeezes the locking block 12, causing the elastic element 11 to contract and the locking block 12 to move into the groove 10; and a telescopic rod 13 installed between the locking block 12 and the groove 10, configured such that when the elastic element 11 contracts, the telescopic rod 13 contracts, so that the locking block 12 smoothly enters the groove 10; the elastic element 11 is a spring or rubber.

[0029] like Figures 4 to 6 As shown, it also includes: an annular groove 14, which is formed on the connecting ring 4, for rotating the oxygen tube 3 so as to release the locking block 12 from the fixing block 8.

[0030] Example 2: Figures 2 to 3 As shown, the second connecting part includes: two sets of rotating blocks 15, both mounted on the fixing ring 7; two sets of limiting frames 16, both mounted on the connecting ring 4, configured to rotate the rotating blocks 15 after the oxygen tube 3 is inserted into the connecting ring 4 of the oxygen inhalation tube 2, so that the rotating blocks 15 are inserted into the limiting frames 16, so that the fixing block 12 and the fixing block 8 are engaged; the limiting frame 16 has a slot (not shown in the figure) on the side away from the connecting ring 4, so that the limiting area 20 of the rotating block 15 is inserted.

[0031] like Figures 2 to 3As shown, it also includes: two sets of support plates 17, which are mounted on the fixed ring 7; and a rotating shaft 18, which is mounted between the two sets of support plates 17 and rotatably connected to the two sets of support plates 17, so that the rotating plate is rotatably connected to the two sets of support plates 17.

[0032] like Figures 2 to 3 As shown, the rotating block 15 includes: a rotating area 19 for connecting to the rotating shaft 18; and a limiting area 20 for inserting into the limiting frame 16.

[0033] The technical solution provided by this utility model requires medical staff to first obtain an oxygen supply mask, ensuring that the mask body 1, oxygen inhalation tube 2, oxygen tube 3, and all connecting parts (including all components of the first and second connecting parts) are intact and free from foreign objects and blockages. Then, connect the oxygen tube 3 to the oxygen source, ensuring that the oxygen source is in normal working condition and that the oxygen supply parameters (such as flow rate and pressure) meet the patient's needs. Hold the oxygen tube 3 and bring it close to the side of the oxygen inhalation tube 2.

[0034] Due to the magnetic attraction between the first magnetic connector 5 (located in the connecting ring 4 of the oxygen tube 2) and the second magnetic connector 6 (located on one side of the oxygen tube 3) in the first connecting part, the oxygen tube 3 will be automatically attracted and initially positioned near the oxygen tube 2. This step does not require precise alignment. The magnetic attraction is used to quickly bring the two closer together, which facilitates subsequent connection operations and is especially suitable for emergency situations.

[0035] Under the magnetic attraction, the oxygen tube 3 is further inserted into the connecting ring 4 of the oxygen tube 2. During this process, multiple sets of fixing blocks 8 on the oxygen tube 3 (evenly distributed on the outer wall between the fixing ring 7 and the second magnetic connector 6) will be aligned with multiple sets of fixing slots 9 on the connecting ring 4 of the oxygen tube 2. When the oxygen tube 3 is fully inserted into the connecting ring 4, each set of fixing blocks 8 is accurately inserted into the corresponding set of fixing slots 9, thereby restricting the relative movement of the oxygen tube 3 and the oxygen tube 2 in the radial direction and ensuring the accuracy of the connection. As the oxygen tube 3 is inserted into the connecting ring 4, the fixing blocks 8 will squeeze the locking blocks 12 in the locking block 12 assembly.

[0036] The locking block 12 assembly is installed in each fixing groove 9 and consists of a groove 10, an elastic element 11, a locking block 12, and a telescopic rod 13. When the fixing block 8 presses the locking block 12, the locking block 12 moves into the groove 10, causing the elastic element 11 to contract. At the same time, the telescopic rod 13 also contracts to ensure that the locking block 12 can smoothly enter the groove 10. After the fixing block 8 has completely passed the locking block 12, the elastic element 11 returns to its original state, and the locking block 12 pops out and inserts into the gap between the fixing block 8 and the fixing ring 7, thereby axially restricting the relative movement of the oxygen tube 3 and the oxygen inhalation tube 2, preventing the oxygen tube 3 from coming out, and completing the fixing operation of the first connection part.

[0037] After the first connecting part is fixed, the second connecting part is operated. The two sets of rotating blocks 15 mounted on the fixing ring 7 are rotated (the rotating blocks 15 rotate around the rotating shaft 18 via the rotating area 19, and the rotating shaft 18 is mounted between the two sets of support plates 17), and the limiting area 20 of the rotating blocks 15 is inserted into the two sets of limiting frames 16 on the connecting ring 4. In this way, the second connecting part further restricts the relative movement of the oxygen tube 3 and the oxygen inhalation tube 2 from multiple directions, strengthening the connection's rigidity based on the first connecting part. This ensures that the entire connection structure can work stably in complex medical environments (such as patient movement, equipment shaking, etc.), guaranteeing a continuous and stable delivery of oxygen to the mask body 1.

[0038] When it is necessary to disassemble the oxygen tube 3 and the oxygen inhalation tube 2, first operate the annular groove 14 on the connecting ring 4. By rotating the oxygen tube 3, the structure of the annular groove 14 releases the fixation between the locking block 12 and the fixing block 8. During the rotation, the relative position of the locking block 12 and the fixing block 8 changes, and the locking block 12 disengages from the gap between the fixing block 8 and the fixing ring 7, thereby eliminating a limiting factor in the axial direction of the oxygen tube 3. After the locking block 12 is released, rotate the rotating block 15 in the opposite direction. The limiting area 20 of the rotating block 15 disengages from the limiting frame 16, thereby releasing the reinforcing fixation effect of the second connecting part on the connection between the oxygen tube 3 and the oxygen inhalation tube 2.

[0039] After completing the above two steps, pull the oxygen tube 3 out of the connecting ring 4 of the oxygen inhalation tube 2, thus completing the disassembly operation of the oxygen tube 3 and the oxygen inhalation tube 2. After disassembly, the various parts of the oxygen supply mask can be cleaned, disinfected or replaced for maintenance operations, in preparation for the next use.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
