Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a high-flow adapter for an oxygen mask. Background Art

[0002] An oxygen mask is a device that transfers oxygen from an oxygen tank to the human lungs. It can cover the nose and mouth (oral nasal mask) or the entire face (full face mask), and plays an important role in ensuring human health and protecting the safety of pilots and airline passengers. In order to transport oxygen, the oxygen mask and oxygen tank need to be connected through an oxygen tube. In order to improve the stability and airtightness of the connection between the oxygen mask and the oxygen tube, an adapter is needed.

[0003] The traditional adapter adopts a structure of a thick tube combined with a thin tube, with the thick tube end connected to the oxygen mask and the thin tube end connected to the oxygen tube. However, some patients experience acute hypoxia and need a large amount of oxygen inhalation. The inner diameter of the traditional oxygen tube is too small to meet the oxygen inhalation needs. At this time, it is necessary to replace it with a high-flow humidification therapy device, but the diameter of the high-flow humidification therapy device does not match the oxygen mask and cannot be connected to the oxygen mask. It can only be fixed with tape, but the tube and the oxygen mask still do not fit, which has the disadvantages of easy leakage, unstable fixation, and inconvenient operation.

[0004] Therefore, how to provide a high-flow adapter for oxygen masks to improve the airtightness, convenience and stability of the connection of high-flow humidification therapy devices has become a technical problem that needs to be solved urgently. Utility Model Content

[0008] Two rubber rings are respectively sleeved on the transfer tube through one of the annular grooves;

[0009] at least one pressure relief valve, disposed in the pressure relief hole;

[0010] an air filter, arranged inside the transfer tube and above the reinforcing rib;

[0011] At least four elastic buckles are symmetrically arranged at the top of the adapter tube.

[0012] Further, the pressure relief hole is located between the annular protrusion and the upper annular groove.

[0013] Further, the reinforcing rib is a cross-shaped reinforcing rib.

[0032] The embodiment of the utility model provides a high-flow adapter 100 for an oxygen mask, thereby solving the problem in the prior art that the size of the high-flow humidification therapy device pipeline does not match the oxygen mask, and can only be fixed with tape, but the pipeline and the oxygen mask still do not fit well, and there are technical problems such as easy leakage, unstable fixation, and inconvenient operation. The utility model achieves the technical effect of greatly improving the convenience and stability of the connection of the large-flow oxygen tube and greatly improving the safety of the use of the adapter.

[0033] The technical solution in the embodiment of the utility model is to solve the above-mentioned problem, and the overall idea is as follows: the threads in the pipeline of the high-flow humidification therapy device are hooked by the elastic undercut 5 to prevent loosening, and the anti-slip groove 15 of the adapter tube 1 and the sleeved rubber ring 2 are combined to ensure a tight fit, so as to improve the air tightness, convenience and stability of the connection of the high-flow humidification therapy device.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Please refer to Figures 1 to 5 As shown, a preferred embodiment of a high flow adapter 100 for an oxygen mask of the utility model comprises:

[0036] A section of adapter tube 1 has an annular protrusion 11 and two annular grooves 12 on its outer sidewall. The annular protrusion 11 is located in the middle, and the two annular grooves 12 are respectively located above and below the annular protrusion 11. The sidewall is provided with at least one pressure relief hole 13 and internally provided with a reinforcing rib 14. The size of the adapter tube 1 matches the size of the air inlet hole of the oxygen mask 6 and the size of the pipeline (not shown) of the high-flow humidification treatment instrument. The annular protrusion 11 is used for the connection between the adapter 100 and the oxygen mask 6. The annular groove 12 is used for the installation of the rubber ring 2. The pressure relief hole 13 is used for the pressure relief of the adapter 100. The reinforcing rib 14 is used to enhance the strength of the adapter 100 and prevent the air filter 4 from being damaged due to the forceful extrusion of the adapter 100 during the plugging and unplugging process.

[0037] Two rubber rings 2 are respectively sleeved on the adapter tube 1 through one of the annular grooves 12 to improve the airtightness of the connection.

[0038] At least one pressure relief valve 3 is arranged in the pressure relief hole 13 for pressure relief when the internal pressure of the adapter 100 is too high.

[0039] An air filter 4 is arranged inside the adapter tube 1, above the reinforcing rib 14, for filtering air.

[0040] At least four elastic buckles 5 are symmetrically arranged at the top end of the adapter tube 1 for connecting the pipeline of the high-flow humidification treatment instrument.

[0041] The pressure relief hole 13 is located between the annular protrusion 11 and the upper annular groove 12.

[0042] The reinforcing rib 14 is a cross-shaped reinforcing rib.

[0043] The reinforcing rib 14 is provided with several through holes 141.

[0044] The outer wall of the adapter tube 1 is provided with several anti-slip lines 15 to effectively improve the stability of the connection.

[0045] The number of the elastic buckles 5 is six.

[0046] At least two clamping parts 51 are arranged on the outer side of the elastic buckle 5 to further improve the stability of the connection.

[0047] The two clamping parts 51 are arranged vertically.

[0048] The working principle of the present utility model:

[0049] Put two circles of the rubber rings 2 into annular grooves 12 respectively, insert one end of the adapter 100 into the pipeline of the high-flow humidification therapy device through the elastic buckle 5, and during the insertion process, hook the thread in the pipeline through the elastic buckle 5 until the pipeline is put on the nearest rubber ring 2; insert the other end of the adapter 100 into the air inlet hole of the oxygen mask 6 until the oxygen mask 6 is stuck on the annular protrusion 11 to complete the connection of the adapter 100.

[0050] In summary, the advantages of the present invention are:

[0051] 1. By symmetrically setting multiple elastic undercuts on the top of the adapter tube that matches the size of the large-flow oxygen tube, when the adapter is connected to the pipeline of the high-flow humidification therapy device, the threads in the pipeline can be hooked by the elastic undercuts to prevent loosening. There is no need to bond with tape as traditionally. Combined with the anti-slip texture of the adapter tube and the rubber ring, the tight fit is guaranteed, thereby greatly improving the airtightness, convenience and stability of the connection of the high-flow humidification therapy device.

[0052] 2. By setting a pressure relief hole on the side wall of the adapter and a pressure relief valve in the pressure relief hole, the pressure can be automatically relieved when the pressure is too high, avoiding discomfort to the patient caused by high pressure, thereby greatly improving the safety of the adapter.

[0053] 3. By setting an annular protrusion in the middle of the outer wall of the adapter tube, it can be effectively fixed on the oxygen mask. Combined with the anti-slip groove of the adapter tube and the rubber ring, the stability of the oxygen mask connection is greatly improved.

[0054] 4. By setting an air filter inside the adapter, the quality of oxygen delivery is guaranteed; by setting reinforcing ribs inside the adapter, the strength of the adapter is effectively improved to avoid damaging the air filter when using the adapter.
