Description

Technical Field

[0001] The utility model relates to the technical field of oxygen inhalation therapy, in particular to a high-flow oxygen inhalation mask. Background Art

[0002] In the medical field, especially in emergency, intensive care, anesthesia resuscitation, neonatal wards and other environments, high-flow oxygen masks are a commonly used respiratory assistance device. It provides patients with high-concentration, high-flow, humidified oxygen to meet the treatment needs of patients facing dyspnea, hypoxemia and other conditions. However, in actual clinical applications, existing high-flow oxygen masks still have some obvious problems.

[0003] First, most of the existing high-flow oxygen masks cannot accurately control the oxygen flow rate. For example, some oxygen masks use a fixed oxygen flow rate, and patients cannot adjust it according to their own needs. For some oxygen masks that can adjust the oxygen flow rate, the adjustment method mostly uses mechanical knobs, which are complicated to operate and lack precision, making it difficult to meet the patient's delicate needs for oxygen flow at different stages of the disease.

[0004] Secondly, traditional oxygen masks often have problems during the oxygen supply process due to excessive moisture content. Because during the oxygen inhalation process, oxygen needs to be humidified to reduce irritation to the patient's respiratory tract. However, excessive moisture will condense inside the mask to form water mist, which not only affects the patient's vision, but also causes the patient to feel stuffy and uncomfortable. In addition, excessive moisture may drip onto the patient's face, causing discomfort.

[0005] Furthermore, the existing high-flow oxygen masks have not been designed with patient comfort in mind. After long-term use, some oxygen masks may cause pressure sores or allergic reactions in patients due to friction between the rubber or silicone material and the skin. At the same time, factors such as the weight, size, and shape of the mask will also affect the patient's comfort.

[0006] In general, the existing high-flow oxygen masks still have much room for improvement in terms of precise control of oxygen flow, moisture management, and patient comfort. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 A high-flow oxygen inhalation mask comprises a mask 1, a mounting sleeve 11 connected to the inner cavity of the mask 1 is fixedly connected to the top of the mask 1, a vent 12 is opened on the bottom side wall of the mask 1, an inverted water collection tank 13 is provided on the outer edge of the mask 1, and the mask 1 also comprises an oxygen supply regulating component 2 and a water removal component 3 installed in the mounting sleeve 11, and the water removal component 3 is arranged on the inner side of the oxygen supply regulating component 2.

[0031] The oxygen supply regulating assembly 2 comprises a T-shaped assembly tube 21, a blocking piston 22 and an adjusting knob 23. The T-shaped assembly tube 21 is provided with a transversely arranged main pipeline 211 and a longitudinally distributed auxiliary pipeline 212 which is connected to the main pipeline 211. The auxiliary pipeline 212 is fixedly installed on the outer end of the mounting sleeve 11, and a strip through hole 2121 is provided in the auxiliary pipeline 212. The adjusting knob 23 is rotatably installed on one end of the main pipeline 211, and the other end of the main pipeline 211 is used to connect the oxygen supply conduit. The blocking piston 22 is slidably installed in the main pipeline 211, and a threaded rod 221 is fixedly connected to the end of the blocking piston 22, and the threaded rod 221 is kept in rotation with the adjusting knob 23.

[0032] This product is a disposable item. To limit the overall cost, the mask 1 is made entirely of silicone die-casting, while the oxygen supply adjustment component 2 and the water removal component 3 are both made of environmentally friendly plastic.

[0033] The high-flow oxygen mask 1 provided by this product is used in conjunction with a high-flow respiratory oxygen therapy integrated machine. The main pipeline 211 is connected to the high-flow respiratory oxygen therapy integrated machine through an oxygen supply conduit. The high-flow respiratory oxygen therapy integrated machine can generate oxygen with a specific oxygen concentration, humidity, and temperature and transport it to the oxygen supply adjustment component 2. By rotating the adjustment knob 23 to drive the threaded rod 221 and the blocking piston 22 to move axially, the blocking area of ​​the blocking piston 22 on the strip through hole 2121 is controlled, thereby achieving precise adjustment of the oxygen supply flow.

[0034] Since the transported oxygen contains a certain amount of moisture, in order to prevent the moisture from condensing and gathering in the installation sleeve 11 and affecting the normal transport of oxygen, the dehydration component 3 assembled on the inner side of the oxygen supply regulating component 2 can be used to remove water to ensure the stable transport of oxygen.

[0035] In order to prevent moisture from condensing and fogging on the inner wall of the mask 1 and causing discomfort such as suffocation to the treated patient, an environmentally friendly water-based coating, nano-coating, or organic coating may be coated on the inner wall of the mask 1 to effectively prevent fogging on the mask 1.

[0036] The inward-turned water collecting groove 13 arranged on the outer edge of the mask 1 can not only ensure the comfort of the mask 1 when it is in contact with the facial skin, but also collect the condensed liquid water because the water condensed on the inner wall of the mask 1 is arranged in the water collecting groove 13 to prevent it from falling into the patient's face and causing discomfort.

[0037] The vent 12 is a necessary configuration of the mask 1 to facilitate the effective discharge of carbon dioxide and water vapor exhaled by the patient and ensure the oxygen concentration in the inner cavity of the mask 1.

[0038] In order to ensure that the end of the main pipeline 211 can be stably connected to the oxygen supply conduit, ensure that the adjustment knob 23 is stably installed on the main pipeline 211, ensure that the blocking piston 22 is stably assembled in the main pipeline 211 and realize the adjustment of the oxygen supply, the following technical solution is provided.

[0039] An annular buckle and an outer limit ring 2112 are provided on the outer side wall of one end of the main pipe 211, and the oxygen supply tube is installed on the main pipe 211 and fits with the annular buckle and the outer limit ring 2112; an annular buckle 2113 is fixedly connected to the outer side wall of the other end of the main pipe 211, and the adjusting knob 23 is sleeved on the outer side of the annular buckle 2113 and can keep free rotation; an inner limit ring 2114 is fixedly connected to the inner wall of the main pipe 211, and the blocking piston 22 is arranged on the inner side of the inner limit ring 2114.

[0040] The provision of the annular buckle and the outer limiting ring 2112 can ensure that the oxygen supply conduit and the main pipeline 211 are stably plugged together, and at the same time ensure the airtightness at the plugging position of the two. The provision of the annular buckle 2113 can ensure that the adjusting knob 23 is stably sleeved thereon and can rotate freely, thereby ensuring the stability of the installation of the adjusting knob 23 on the main pipeline 211. The provision of the limiting piston can prevent the blocking piston 22 from being stably assembled in the main pipeline 211.

[0041] In addition, an oxygen supply port is opened at one end of the blocking piston 22 facing the oxygen supply tube assembly position, and the oxygen supply port is connected with the strip through hole 2121 and the main pipeline 211, and cooperates with the inner limit ring 2114 to prevent the blocking piston 22 from completely blocking the strip through hole 2121 due to operational errors, resulting in poor oxygen supply.

[0042] A guide rail is also provided on the inner wall of the main pipe 211, and the blocking piston 22 is slidably plugged into the guide rail to ensure that the blocking piston 22 slides stably in a straight line direction.

[0043] The blocking piston 22 and the adjusting knob 23 assembled in the main pipe 211 can be quickly assembled from the side of the main pipe 211 provided with the annular buckle 2113, thereby ensuring the efficiency of mass production of the mask 1.

[0044] When the adjusting knob 23 drives the blocking piston 22 to move toward the side of the adjusting knob 23, in order to prevent the adjusting knob 23 from causing motion interference with the threaded rod 221, a clearance cavity 231 is opened at the axis of the adjusting knob 23, and the threaded rod 221 can be arranged in the clearance cavity 231 to ensure that there is no motion interference between the two.

[0045] In order to ensure that the bottom end of the secondary pipeline 212 can be stably assembled on the mounting sleeve 11 and to ensure the stable assembly of the oxygen supply regulating assembly 2, the following technical solution is also provided.

[0046] A connecting sleeve 24 is sleeved on the outer periphery of the secondary pipeline 212 , and the connecting sleeve 24 is screwed to the outer wall of the installation sleeve 11 .

[0047] The end of the auxiliary pipe 212 is designed in a stepped shape, which can ensure that the connecting sleeve 24 is stably assembled on the auxiliary pipe 212 and achieve the effect of free sliding and rotation. After the auxiliary pipe 212 is docked with the outer end of the mounting sleeve 11, the knob connecting sleeve 24 is used to fix it on the mounting sleeve 11, thereby achieving a stable connection between the T-shaped assembly pipe 21 and the mounting sleeve 11.

[0048] In order to ensure that the water removal assembly 3 can be stably installed on the inner side end of the installation sleeve 11 and realize the water removal function, the following technical solution is provided.

[0049] The water removal assembly 3 includes a water collecting seat 31, a water retaining cap 32, and a fixing nut 33. The water collecting seat 31 is screwed into the mounting sleeve 11, and an oxygen supply cavity 311 and an assembly through hole are provided at the center of the water collecting seat 31. The assembly through hole is arranged at the bottom of the oxygen supply cavity 311 and is connected to the oxygen supply cavity 311. The bottom of the oxygen supply cavity 311 is also provided with an oxygen supply through hole 312 arranged at the periphery of the assembly through hole. A plug-in column 321 inserted into the assembly through hole is fixedly connected at the center of the bottom of the water retaining cap 32. A limiting plate 322 that is abutted against the bottom wall of the oxygen supply cavity 311 is fixedly connected to the plug-in column 321. The fixing nut 33 is arranged at the bottom of the water retaining cap 32 and is screwed to the plug-in column 321.

[0050] It is extremely easy to assemble the water removal component 3. First, insert the plug-in column 321 at the bottom of the water retaining cap 32 into the assembly through hole of the water collecting seat 31. The setting of the limiting plate 322 can ensure the assembly position of the water retaining cap 32 and the water collecting seat 31. Then, screw the fixing nut 33 onto the plug-in column 321 exposed at the bottom of the water collecting seat 31 to achieve a fixed combination of the water collecting seat 31 and the water retaining cap 32. Then, screw the water collecting seat 31 from the inside of the mask 1 to the inner end of the mounting sleeve 11 to allow the water removal component 3 to extend into the inside of the mounting sleeve 11.

[0051] The delivered oxygen enters the mounting sleeve 11 through the oxygen supply regulating assembly 2 and gathers above the dewatering assembly 3, and enters the oxygen supply cavity 311 through the assembly gap between the water retaining cap 32 and the water collecting seat 31, and then enters the mask 1 through the oxygen supply hole 312 to provide stable oxygen supply to the patient.

[0052] Since the top structure of the water collecting seat 31 is designed with a high center and a low periphery, when the moisture in the transported oxygen is gathered and transported in the installation sleeve 11, part of the moisture condenses into water droplets and gathers on the edge above the water collecting seat 31. The design of the water retaining cap 32 can prevent water droplets from entering the oxygen supply cavity 311 and being transmitted to the inside of the mask 1, thereby preventing a large amount of water mist from being input into the mask 1.

[0053] In the above technical solution for the water removal assembly 3, in order to facilitate the continuous collection and backflow of water accumulated above the water collection seat 31 into the oxygen supply cavity 311 and the oxygen supply hole 312 to affect the normal delivery of oxygen, the following technical solution is provided.

[0054] The mounting sleeve 11 is connected to a drainage pipe arranged outside the mask 1 , and the drainage pipe is arranged above the water collecting seat 31 .

[0055] The provision of the drain pipe can ensure that the liquid water collected above the water collecting seat 31 can be discharged through the drain pipe, and the drain pipe can be plugged into the water pipe to prevent the discharged water from falling into the patient's face and causing discomfort.
