DETAILED DESCRIPTION

[0037] Various exemplary embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments do not limit the scope of the present utility model unless otherwise specifically stated.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting to the scope of the present utility model and its applications or uses.

[0039] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered part of the specification. ​

[0040] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0041] It should be noted that like reference numerals and letters refer to like items throughout the attached drawings, and as a result, once an item is defined in one drawing, it is not necessary to discuss it further in subsequent drawings.

[0042] In an alternative embodiment, with reference to Figures 1-6 The oxygen inhalation device provided by the present embodiment comprises a conversion joint 10, a flow meter 20 fixed on the top of the conversion joint 10, a humidification bottle 30 fixed on the bottom of the conversion joint 10, an air inlet channel 11, an adjusting device 40, an air outlet channel 12 and a control module 50 arranged around the conversion joint 10.

[0043] The top of the flow meter 20 is provided with a distance detector 21 for detecting the distance between the distance detector 21 and a floating ball 22 in the flow meter 20; the humidification bottle 30 is provided with a temperature control unit 31; the adjusting device 40 is used for adjusting the oxygen flow of the output oxygen; a flow limiting device 60 is fixed on the adjusting device 40 for limiting the adjusting range of the adjusting device 40.

[0044] The control module 50 comprises a controller 51 and a display screen 52 electrically connected with the controller 51, the controller 51 is electrically connected with the temperature control unit 31; the controller 51 is used for acquiring the distance detected by the distance detector 21 and determining the oxygen flow based on the distance detected by the distance detector 21; the display screen 52 is used for outputting and displaying the oxygen flow.

[0045] It can be understood that the oxygen will change from high pressure to low pressure, the low pressure oxygen enters the conversion joint 10 from the air inlet channel 11, enters the humidification bottle 30 through the flow meter 20, is outputted by the air outlet channel 12 after the humidification treatment at a constant flow value, and is inhaled by the patient, the flow value is adjusted by the adjusting device 40, in order to prevent the patient or the patient's family member from adjusting the oxygen flow to exceed the patient's adaptation range, the flow limiting device 60 is fixed on the adjusting device 40 to limit the adjusting range of the adjusting device 40.

[0046] Because the original flow meter 20 vertical scale line 23 display is relatively dense, the elderly often can not see the float ball 22 to reach the scale, so that the distance detector 21 is arranged at the top of the flow meter 20, the distance detector 21 and the distance between the float ball 22 in the flow meter 20 H1, the vertical distance between the distance detector 21 and the 0 scale line of the flow meter 20 H0 minus the distance between the distance detector 21 and the float ball 22 in the flow meter 20 H1 is the oxygen flow, the oxygen flow value can be accurately determined by the distance measuring of the distance detector 21, and then output by the display screen 52, the patient can directly observe the oxygen flow displayed by the display screen 52.

[0047] In order to improve the use of oxygen for patients, the humidification bottle 30 humidifies the oxygen, and the temperature control unit 31 in the humidification bottle 30 warms the oxygen, so that the temperature and humidity are in a certain suitable range, effectively ensuring the comfort of the patient in the oxygen environment.

[0048] It should be noted that, with reference to Figure 11 , the display area 53 of the display screen 52 displays the image of the flow tube and the flow value corresponding to the scale line, the humidity and temperature of the oxygen, and the prompt area 54 of the display screen 52 can display the oxygen flow range that the patient should use, the serious consequences of using oxygen flow out of the range, etc., so as to facilitate the patient to observe the size of the oxygen flow and prompt the patient to adjust the oxygen flow.

[0049] In an alternative embodiment, with reference to Figure 3 , the warning signs 24 are arranged at intervals on the vertical scale line 23 of the flow meter 20. It can be understood that the warning signs 24 can be arranged at the low flow, medium flow and high flow vertical scale lines 23 of the flow meter 20, and the patient can observe the warning signs 24 to ensure the correct oxygen flow range. The warning signs 24 can be red line marks.

[0050] In an alternative embodiment, with reference to Figure 4 , the humidification bottle 30 is provided with a temperature detector 32 and a humidity detector 33, and the temperature detector 32 and the humidity detector 33 are electrically connected to the controller 51; the display screen 52 is used to display the temperature and humidity in the humidification bottle 30.

[0051] It can be understood that the heating temperature of the temperature control unit 31 can be adjusted by the controller 51, the temperature detector 32 detects the temperature of the oxygen after heating and humidification, and the humidity detector 33 detects the humidity of the oxygen after heating and humidification; the display screen 52 displays the detected temperature and humidity in the humidification bottle 30.

[0052] In an alternative embodiment, with reference to Figures 5-9The adjusting device 40 comprises a valve body 41, an adjusting switch 42 and an adjusting shaft 43 connecting the valve body 41 and the adjusting switch 42. A scale disc 46 is fixed on the conversion joint 10, and the adjusting shaft 43 penetrates through the scale disc 46 and can rotate in the scale disc 46. Specifically, a pointer 45 is fixed on the adjusting shaft 43, and the scale disc 46 comprises the scale disc 46. A rotation scale line 47 is circumferentially arranged on the surface of the scale disc 46. A dust cover 44 is fixed on the scale disc 46.

[0053] It can be understood that the adjusting switch 42 is rotated, and the adjusting shaft 43 is also rotated, so as to adjust the flow area of the valve body 41 and change the oxygen flow. The size of the oxygen flow can be determined by observing the corresponding rotation scale line 47 of the pointer 45. In order to prevent the surface of the scale disc 46 and the rotation scale line 47 from being contaminated, the dust cover 44 is fixed on the scale disc 46 to prevent dust and contamination.

[0054] In an alternative embodiment, referring to Figures 5-9 The scale disc 46 is provided with a plurality of positioning reminding devices 48. The positioning reminding devices 48 are used to provide resistance to the rotating pointer 45. Specifically, the positioning reminding device 48 comprises a positioning bead 481. A positioning groove 461 is arranged in the scale disc 46. The positioning bead 481 is partially located above the positioning groove 461. A spring 482 is arranged in the positioning groove 461. One end of the spring 482 is fixed at the bottom of the positioning groove 461, and the other end is fixed to the positioning bead 481.

[0055] It can be understood that the size of the oxygen flow is adjusted by rotating the adjusting switch 42. Sometimes, the oxygen flow is changed sharply when the adjusting switch 42 is rotated too fast, which affects the oxygen inhalation of the patient and also affects the adjusting precision of the adjusting device 40. In this regard, a plurality of positioning reminding devices 48 can be arranged in the scale disc 46. When the pointer 45 on the adjusting shaft 43 passes through the positioning reminding device 48, the pointer 45 will feel obvious resistance, which reminds the medical staff and facilitates the accurate adjustment of the adjusting device 40.

[0056] It can be understood that the diameter of the positioning bead 481 is smaller than the diameter of the positioning groove 461, and the positioning bead 481 can move in the positioning groove 461. When the adjusting switch 42 is rotated to the position of the positioning reminding device 48, the positioning bead 481 slightly above the surface of the scale disc 46 generates a certain resistance to the pointer 45. When the adjusting switch 42 is continuously rotated, the pointer 45 exerts pressure on the positioning bead 481, and the positioning bead 481 is compressed under pressure, which is equivalent to the downward movement of the pointer 45. The positioning bead 481 no longer provides resistance to the movement of the pointer 45, and the adjusting switch 42 can be continuously rotated.

[0057] It should be noted that the positioning reminder device 48 can be arranged at the positions corresponding to the low-flow, medium-flow and high-flow rotating scale lines 47. The pointer 45 moves without resistance in the low-flow range, the medium-flow range and the high-flow range. When the pointer 45 moves to the position of the positioning reminder device 48, the pointer 45 has a clear jamming feeling, which is used to remind the patient that the oxygen flow has reached the next flow range. The arrangement position of the positioning reminder device 48 can be arranged as required and is not fixed.

[0058] In an alternative embodiment, referring to Figures 7-10 , the dial 46 is provided with a displacement groove set, and a flow limiting device 60 is arranged in the displacement groove set and can move in the displacement groove set. Specifically, the displacement groove set includes a first moving channel 462 and a second moving channel 463 communicating with the first moving channel 462 and the positioning groove 461; the first moving channel 462 includes a first semicircular through groove 464 and a second semicircular groove 465, and the outer edge of the second semicircular groove 465 is provided with a first rotating groove 466 communicating with the second semicircular groove 465 and a second rotating groove 467 communicating with the second semicircular groove 465. The flow limiting device 60 matched with the displacement groove set includes a moving rod 61 and a limiting rod 62 fixed on the moving rod 61, and the moving rod 61 can move in the first moving channel 462 and the second moving channel 463; the length of the limiting rod 62 is greater than the radius of the second semicircular groove 465 and less than the radius of the first semicircular through groove 464.

[0059] It can be understood that, in order to limit the adjustment range of the oxygen flow and prevent the patient from adjusting the oxygen flow out of range, the moving distance of the flow limiting device 60 in the displacement groove set is adjusted to limit the rotation of the pointer 45 and further limit the adjustment range of the adjustment device 40.

[0060] It can be understood that the first moving channel 462 is composed of the first semicircular through groove 464 and the second semicircular groove 465 with different diameters, the first semicircular through groove 464, the second semicircular groove 465 and the second moving channel 463 have the same axis, the upper part of the moving rod 61 is in the second moving channel 463, the middle part of the moving rod 61 is in the first channel, and the lower part of the moving rod 61 is outside the dial 46. When the limiting rod 62 on the moving rod 61 is located in the first semicircular through groove 464, the moving rod 61 can move up and down. When the limiting rod 62 on the moving rod 61 is located in the same horizontal space as the first rotating groove 466 or the second rotating groove 467, the moving rod 61 is rotated, the limiting rod 62 on the moving rod 61 can be moved into the first rotating groove 466 or the second rotating groove 467, at this time, the moving rod 61 is loosened, because the limiting rod 62 of the moving rod 61 is fixed in the first rotating groove 466 or the second rotating groove 467, the moving rod 61 no longer moves.

[0061] When the limiting is needed, the moving rod 61 is rotated to move the limiting rod 62 from the first rotating groove 466 to the first semicircular groove 464, and then the moving rod 61 is moved to move the limiting rod 62 in the second rotating groove 467 when the moving rod 61 is above the positioning bead 481, and the top end of the moving rod 61 is above the surface of the dial 46 to completely block the movement of the pointer 45 and limit the oxygen flow adjustment range.

[0062] When the limiting is not needed, the moving rod 61 is rotated to move the limiting rod 62 from the first rotating groove 466 to the second semicircular groove 465, and then the moving rod 61 is moved to move the limiting rod 62 in the first rotating groove 466 when the moving rod 61 is below the positioning bead 481, and the top end of the moving rod 61 is below the surface of the dial 46 to no longer block the movement of the pointer 45 and limit the oxygen flow adjustment range.

[0063] It should be noted that the displacement groove group and the flow limiting device 60 can be used with the positioning reminder device 48 or can be used alone, and the size and position of the first moving channel 462, the first semicircular groove 464, the second semicircular groove 465, the second moving channel 463, the first rotating groove 466, the second rotating groove 467, the moving rod 61 and the limiting rod 62 can be changed. When the limiting is needed, the moving rod 61 is rotated to move the limiting rod 62 from the first rotating groove 466 to the first semicircular groove 464, and then the moving rod 61 is moved to move the limiting rod 62 in the second rotating groove 467 when the moving rod 61 is above the adjusting switch 42, and the top end of the moving rod 61 is above the surface of the dial 46 to completely block the movement of the pointer 45 and limit the oxygen flow adjustment range.

[0064] When the limiting is not needed, the moving rod 61 is rotated to move the limiting rod 62 from the first rotating groove 466 to the second semicircular groove 465, and then the moving rod 61 is moved to move the limiting rod 62 in the first rotating groove 466 when the moving rod 61 is below the positioning bead 481, and the top end of the moving rod 61 is below the surface of the dial 46 to no longer block the movement of the pointer 45 and limit the oxygen flow adjustment range.

[0065] When the oxygen inhalation device of the embodiment is used, whether to limit the oxygen flow adjustment range is determined according to the need, when needed, the flow limiting device 60 is used to limit the oxygen flow adjustment range, the moving rod 61 is rotated, the limiting rod 62 is moved out of the first rotating groove 466 into the space of the first semicircular groove 464, then the moving rod 61 is moved, the moving rod 61 is moved upward relative to the positioning bead 481, when the moving rod 61 is in the same horizontal space with the second rotating groove 467, the limiting rod 62 on the moving rod 61 can be moved into the second rotating groove 467, at this time, the top end of the moving rod 61 abuts against the positioning bead 481, the positioning bead 481 is moved upward, the movement of the pointer 45 is completely blocked, the limitation of the oxygen flow adjustment range is realized. When not needed, the flow limiting device 60 is not used.
