[0033] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] The following is combined with Figure 1-5 The present application is further described in detail. An embodiment of the present application discloses an oxygen therapy gas delivery mask.

[0035] Reference Figure 1 and Figure 2 As shown, an oxygen therapy gas delivery mask includes a nasal mask 100, an oxygen delivery tube 110, a water storage bottle 200 and a guide component. The oxygen delivery tube 110 is connected to the side wall of the nasal mask 100 to deliver oxygen into the nasal mask 100. The water storage bottle 200 is connected to the nasal mask 100 through the guide component to collect condensed water accumulated on the inner wall of the nasal mask 100. The condensed water flows through the guide component and is collected in the water storage bottle 200. In this way, the problem of condensed water accumulating in large quantities on the nasal mask 100 and flowing back to the patient, causing respiratory tract infection, is reduced.

[0036] The oxygen supply tube 110 is fixedly connected to the side wall of the nasal mask 100, and when the nasal mask 100 is in use, the oxygen supply tube 110 is just located above the patient's lower jaw, and the direction in which the oxygen supply tube 110 connects to the end of the nasal mask 100 and inputs oxygen into the nasal mask 100 is just toward the patient's nostrils, thereby facilitating the input oxygen to be better inhaled by the patient and reducing oxygen waste.

[0037] Reference Figure 3 and Figure 4As shown, the guide component includes a pressure ring 120, which is arranged at the edge of the nasal mask 100 contacting the patient's skin and is fixedly connected to the inner wall of the nasal mask 100, and the pressure ring 120 can be sleeved at the edge of the nasal mask 100, or can be integrally arranged with the pressure ring 120. The sleeved pressure ring 120 can be selected to have a higher softness to reduce the pressure of the nasal mask 100 on the patient's skin.

[0038] Preferably, the pressing ring 120 is integrally provided with the nasal mask 100, and a drainage channel 130 is provided on the pressing ring 120. The drainage channel 130 is provided along the circumferential direction of the edge of the nasal mask 100, that is, the side wall of the drainage channel 130 is formed by the side wall of the pressing ring 120 facing the inner wall of the nasal mask 100 and the inner wall of the nasal mask 100. The cross section of the drainage channel 130 is V-shaped, that is, the drainage channel 130 corresponds to the side wall of the nasal mask 100 and smoothly butts with the inner wall of the nasal mask 100. The drainage channel 130 is inclined corresponding to the side wall of the pressing ring 120, that is, it gradually expands outward from the bottom surface of the drainage channel 130.

[0039] Therefore, when the water vapor exhaled by the patient accumulates on the inner wall of the nasal mask 100, the water vapor accumulates into water droplets on the inner wall of the nasal mask 100, and the water droplets slide down along the inner wall of the nasal mask 100 under the action of gravity and just slide into the docking drainage channel 130. In this way, the accumulated condensed water is guided and collected into the water storage bottle 200.

[0040] The V-shaped drainage channel 130 is convenient for collecting condensed water and increases the water storage space. In addition, the V-shaped receiving groove facilitates the flow of condensed water when there is less condensed water.

[0041] Reference Figure 4 and Figure 5 As shown, the guide component further includes a drainage tube 210 , which is fixedly connected to the side wall of the nasal mask 100 and communicates with the drainage channel 130 .

[0042] The drainage tube 210 is arranged below the oxygen supply tube 110 during the use of the nasal mask 100 (i.e., the drainage tube 210 is closer to the patient's mouth during the use of the patient). The drainage tube 210 is arranged above the corner of the patient's mouth during the use of the nasal mask 100, i.e., the drainage tube 210 is arranged in an inclined direction, from the corner of the patient's mouth toward the nasal cavity (the direction of the drainage tube 210 is when the nasal mask 100 is worn in the standard state)

[0043] A guide channel 140 is provided at the connection between the guide channel 130 and the guide tube 210, and the bottom surface of the guide channel 140 is lower than the guide channel 130. This facilitates the collection of condensed water in the guide channel 130, and facilitates the introduction of condensed water in the guide channel 130 into the guide tube 210, thereby preventing the condensed water from being retained in the guide channel 130.

[0044] The drainage tube 210 is provided with a guide surface 150, which is disposed at the bottom surface where the drainage tube 210 contacts the drainage channel 130, and extends outward from the end of the drainage tube 210 at the drainage channel 130 along the length direction of the drainage tube 210. This facilitates the flow of condensed water from the drainage channel 130 to the drainage tube 210, and reduces the retention of condensed water at the connection between the drainage tube 210 and the drainage channel 130.

[0045] The guide component further includes a curved tube 220, one end of which is connected to the end of the drainage tube 210 away from the nasal mask 100. The curved tube 220 is sleeved on the drainage tube 210, that is, the curved tube 220 is detachably connected to the drainage tube 210. The other end of the curved tube 220 can be connected to a long tube and communicated with the water storage bottle 200 according to the use environment.

[0046] It is convenient to adjust the length of the long tube according to the usage scenario to improve the applicability of use.

[0047] Reference Figure 4 and Figure 5 As shown, a connecting pipe 230 for connecting to the inside of the water storage bottle 200 is fixedly provided at one end of the water storage bottle 200 , and a drain port 260 for drainage is opened at the other end of the water storage bottle 200 , and a sealing member 240 is sealed on the drain port 260 .

[0048] The connecting tube 230 is connected to the other end of the curved tube 220 to facilitate the collection of condensed water. The setting of the curved tube 220 changes the direction of the drainage tube 210, facilitates the setting of the position of the water storage bottle 200, and avoids the water storage bottle 200 affecting the patient's treatment process.

[0049] The plugging member 240 is a sealing column, one end of which is inserted into the drain port 260, and the side wall of the sealing column is interference fit with the drain port 260. A sealing cap 250 is fixedly arranged at the top of the sealing column, and the sealing cap 250 is arranged in the water storage bottle 200, and the size of the sealing cap 250 is larger than the size of the drain port 260 and smaller than the radial size of the inner cavity of the water storage bottle 200, so that the sealing column can be pulled to drive the sealing cap 250 to plug the drain port 260 from the inside of the water storage bottle 200.

[0050] The sealing column is provided with a drainage groove 290 at one end away from the sealing cover 250, and the drainage groove 290 is provided along the axial direction of the sealing column. A through hole 280 is provided through the sealing column along its radial direction, and the through hole 280 is connected to the drainage groove 290. When the condensed water in the water storage bottle 200 needs to be released, the sealing column is pushed to move into the water storage bottle 200, and the sealing cover 250 is driven to move. Then the port of the through hole 280 is located in the water storage bottle 200, so that the condensed water enters the drainage groove 290 from the through hole 280 and is discharged from the port of the drainage groove 290.

[0051] The end of the sealing column away from the sealing cover 250 is provided with a tapered end 270, and the diameter of the sealing column gradually increases from the through hole 280 to the end away from the sealing cover 250. In this way, when the sealing column is pushed to move into the water storage bottle 200, when the sealing column clamps the side wall of the drain port 260, the through hole 280 is just completely connected to the inner cavity of the water storage bottle 200. In addition, the operator does not need to continuously push the sealing column to keep the through hole 280 connected.

[0052] Reduce the spread of bacteria and viruses during use and facilitate operation.

[0053] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
