[0001] The present application relates to the technical field of oxygen humidification, and in particular to a humidifier for a medical oxygen concentrator. Background Art

[0002] At present, oxygen concentrators are usually equipped with humidifiers to humidify the oxygen inhaled by patients, thereby preventing and reducing secondary respiratory infections, reducing stimulation to the cardiopulmonary system, keeping the alveoli moist, and reducing the consumption of heat and respiratory water, making it less likely for sputum crusts to form in the airways, reducing the viscosity of secretions, and promoting expectoration.

[0003] The humidifier includes a humidifier bottle, and water needs to be added to the humidifier bottle when it is used. In order to prevent cross infection caused by oxygen inhalation, the humidifier bottle must be disinfected and sterilized regularly. However, there are some disadvantages when the existing humidifier bottle is used with a medical oxygen machine, such as:

[0004] Because the oxygen output by the oxygen concentrator flows through the air duct inside the humidifier, the gas flows into the water through the air duct, causing a loud bubbling noise, which cannot meet the requirements for use in a quiet room. It is also easy to cause water splashing, causing the human body to inhale water droplets, which can easily irritate the airway. Utility Model Content

[0026] The technical solution of the present application will be clearly and completely described below in conjunction with specific implementation schemes, but those skilled in the art should understand that the implementation schemes described below are only used to illustrate the present application and should not be regarded as limiting the scope of the present application. Based on the implementation schemes in the present application, all other implementation schemes obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0027] like Figure 1-2 As shown, a humidifier for a medical oxygen concentrator provided in an embodiment of the present application includes a humidification bottle 1, a bottle cap 2, a bracket 3 and a filter cotton swab 4;

[0028] A bottle cap 2 is sealed on the top of the humidification bottle 1, and an air inlet 21 is provided on the bottle cap 2. The air inlet 21 is used to connect to an oxygen generator. An oxygen outlet 22 is also provided on the bottle cap 2. The oxygen outlet 22 is used to output humidified oxygen.

[0029] In a specific implementation, the air inlet 21 can be set on the side of the bottle cap 2, and the oxygen outlet 22 can be set in the center of the bottle cap 2, which is not limited here and can be set according to actual needs;

[0030] A bracket 3 is arranged inside the humidification bottle 1. The bracket 3 can be made of plastic. The outer edge structure of the bracket 3 matches the cross-sectional structure of the humidification bottle 1, so that the outer edge of the bracket 3 is sealed and clamped in the humidification bottle 1.

[0031] In the embodiment of the present application, since the humidification bottle 1 is a cylindrical bottle body, the outer edge of the supporting bracket 3 is a circular structure. However, it is not limited thereto. When the humidification bottle 1 is a square bottle body, the outer edge of the supporting bracket 3 can also be set to a square structure.

[0032] A connecting plate 31 is provided on the inner side of the outer edge of the bracket 3, and a water hole 32 is provided on the connecting plate 31 for water and / or air to pass through. The connecting plate 31 can be inclined toward the location of the water hole 32 to converge and guide water droplets to the water hole 32;

[0033] In the embodiment of the present application, the water hole 32 is arranged on the inner side of the connecting plate 31, so the connecting plate 31 is inclined inward from the outer edge of the bracket 3, and one or more water holes 32 can be provided. In the present embodiment, four water holes 32 are provided at intervals in the circumferential direction, but it is not limited thereto;

[0034] The bracket 3 is also provided with a mounting hole 33, in which a filter cotton stick 4 is inserted, the bottom end of the filter cotton stick 4 is located at the bottom of the humidification bottle 1 to fully absorb the water and oxygen in the humidification bottle 1, and the top end of the filter cotton stick 4 is located at the top of the humidification bottle 1 to transport oxygen to the oxygen outlet 22;

[0035] In the embodiment of the present application, the mounting hole 33 is arranged at a position on the bracket 3 corresponding to the oxygen outlet 22. Since the oxygen outlet 22 is arranged at the center of the bottle cap 2 in the present embodiment, the mounting hole 33 is arranged at the center of the bracket 3. In order to increase the oxygen output, multiple filter cotton sticks 4 can be arranged. In the present embodiment, four filter cotton sticks 4 are arranged at circumferential intervals. For this purpose, four mounting holes 33 are correspondingly arranged on the bracket 3. However, it is not limited to this. In the specific implementation, it can be arranged as needed.

[0036] At the same time, a hollow column 35 can also be provided on the bracket 3 , and the hollow column 35 tightly penetrates the bracket 3 . The hollow column 35 is used to surround the filter cotton swab 4 to further limit and fix the filter cotton swab 4 , and can further collect oxygen to the oxygen outlet 22 .

[0037] The humidifier for medical oxygen concentrator provided in the embodiment of the present application includes the following contents when used:

[0038] Fill the humidification bottle 1 with an appropriate amount of pure water and tighten the bottle cap 2;

[0039] The oxygen outlet 22 on the bottle cap 2 is connected to the oxygen inhalation port of the user, and the air inlet 21 on the bottle cap 2 is connected to the air outlet of the oxygen generator. The oxygen output by the oxygen generator flows through the air inlet 21 and the water pores 32 and enters the humidification bottle 1. After being buffered by the air in the humidification bottle 1, the oxygen is dissolved in the water at the bottom of the humidification bottle 1. After the oxygen and water are mixed, they rise from the bottom to the oxygen outlet 22 along the filter cotton swab 4 and are inhaled into the nasal cavity by the user.

[0040] When the oxygen intake pressure is high, after the filter cotton swab 4 is saturated with water, the excess water on the top of the filter cotton swab 4 can be collected to the water pores 32 through the connecting plate 31 (due to the inclination of the connecting plate 31) and flow into the bottom of the humidification bottle 1 again, so as to achieve multiple utilization.

[0041] In addition, considering the water leakage demand comprehensively, water leakage holes 34 can be provided at the intervals of the mounting holes 33 to ensure that the water seeping out of the filter cotton swab 4 can flow to the bottom of the humidification bottle 1 in time to avoid water accumulation.

[0042] Obviously, through the above arrangement, the embodiment of the present application ensures that the oxygen intake is not directly mixed with the water locally through the trachea, but the oxygen is buffered by the air in the humidification bottle 1 from top to bottom and then melted into the water, and then the oxygen is output through the filter element cotton swab 4. Therefore, the bubble noise and even the splashing of water generated by the oxygen intake are completely eliminated.

[0043] At the same time, through the drainage of the filter cotton swab 4, water droplets will not be directly inhaled into the nasal cavity, and the atomization effect of the oxygen inhaled by the user is more uniform.

[0044] In addition, considering the convenience of disinfection operation, the filter cotton swab 4 is made of soft material and can be directly taken out and replaced by unscrewing the humidifier bottle cap 2, avoiding bacterial and fungal infections caused by repeated use, thereby improving the convenience of use and medical safety of the humidifier. Other parts can be sterilized at high temperature.

[0045] It can be seen that the humidifier for medical oxygen concentrator provided in the embodiment of the present application has an ingenious overall structural design. Through experimental testing and calculation, it meets the output quality requirements of "YY / T1610-2018 Medical Oxygen Humidifier for Anesthesia and Respiratory Equipment" for medical oxygen humidifiers, that is, the humidification output of the medical oxygen humidifier should be at least 7 mg / L.

[0046] The experimental test data are as follows:

[0047] First weight first Second time The third time Fourth Fifth time 13.30 14.30 15.30 16.30 17.30 weight 289.29g 285.45g 282.29g 278.99g 275.22g 271.76g

[0048] According to the working flow range declared by the manufacturer, take the maximum and minimum working flow rates for testing respectively, place the humidifying liquid at the highest liquid level line, the test environment temperature is 22℃±3℃, the test time is 4h or the effective use time specified by the manufacturer, whichever is smaller, and calculate the humidification output Hout using the following formula:

[0049] Hout=(m0-m1) / V 总

[0050] In the above formula: m0 is the initial mass of the medical oxygen humidifier, in milligrams (mg);

[0051] m1 is the mass of the medical oxygen humidifier after the test, in milligrams (mg);

[0052] V 总 It is the total amount of gas passing through the medical oxygen humidifier during the entire test, in liters (L);

[0053] The above calculations show that:

[0054] Hout=(289.29-271.76)*1000 / (5*5*60)=11.69mg / L

[0055] Obviously, the calculation results show that the humidifier output provided in the embodiment of the present application is greater than the standard requirement of 7 mg / L, and meets the requirements of YY / T1610-2018.
