Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an air outlet converter. Background Art

[0002] In the current medical field, key medical gas supply devices such as oxygen generators and ventilators are widely used in patients who need assisted breathing or oxygen therapy, such as patients with chronic obstructive pulmonary disease (COPD), heart failure, sleep apnea syndrome and other patient groups. These devices significantly improve the quality of life and living ability of patients by providing continuous and stable oxygen to patients or regulating the breathing rhythm. However, in the key link of human-machine interaction, that is, in the gas transmission process between the device and the patient, connection devices such as breathing masks or nasal oxygen tubes with pipelines are generally used to achieve effective oxygen supply.

[0003] In order to ensure the tightness and effectiveness of gas transmission, the traditional design often uses an interference fit method to tightly connect the pipeline to the air outlet of the oxygen generator or ventilator to prevent air leakage. Although this design improves the airtightness of the system to a certain extent, it also brings a series of inconveniences in use. Specifically, due to the large insertion and extraction force required for interference fit, it is particularly difficult for elderly patients, the weak or those with limited mobility to insert and extract the pipeline each time, which requires a lot of physical strength and energy, and may even cause unnecessary pain and discomfort.

[0004] In addition, frequent insertion and extraction operations may also cause wear to the connection part. In the long run, it will affect the airtightness and service life of the device, thereby increasing the medical cost and maintenance burden of patients. Therefore, we provide an air outlet converter to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0031] As Figure 1 — Figure 8 shown in the embodiments.

[0032] An air outlet converter includes a first base 1 and a second base 2. Communication pipes 3 are integrally formed on the end faces of the first base 1 and the second base 2 that face away from each other. A first magnetic attraction member 4 is provided on the end face of the first base 1 facing the second base 2, and a second magnetic attraction member 5 is provided on the end face of the second base 2 facing the communication pipe 3. During use, magnetic attraction occurs between the first magnetic attraction member 4 and the second magnetic attraction member 5 to detachably connect the second base 2 and the communication pipe 3.

[0033] In this embodiment, the communication pipe 3 on the end face of the first base 1 can be connected to the air outlet of a ventilator or oxygen generator through a trachea, and then the communication pipe 3 on the end face of the second base 2 is connected to the corresponding breathing mask through a trachea to supply oxygen to the user. Or the communication pipe 3 on the end face of the first base 1 is connected to the breathing mask through a trachea, and the communication pipe 3 on the end face of the second base 2 is connected to the outlet of the ventilator or oxygen generator through a trachea. In this embodiment, the communication pipe 3 on the end face of the first base 1 is connected to the breathing mask, and the communication pipe 3 on the end face of the second base 2 is connected to the air outlet of the ventilator or oxygen generator. The specific connection method can be selected according to actual needs and is not limited here.

[0034] Refer to Figures 1 to 6 shown. During use, first bring the first base 1 and the second base 2 close to and in contact with each other. At this time, magnetic attraction occurs between the first magnetic attraction member 4 and the second magnetic attraction member 5, so that the first base 1 and the second base 2 are connected. At this time, the communication pipe 3 in the first base 1 and the communication pipe 3 in the second base 2 are connected to form a passage, enabling the oxygen from the ventilator or oxygen generator to be transported to the breathing mask through this passage for the user to use.

[0035] Refer to Figure 5 and Figure 6 It can be seen that after the first base 1 is combined with the second base 2, the two connecting pipes 3 are connected to form a passage for oxygen to pass through.

[0036] A first installation groove 6 is formed on the end face of the first base 1. The first magnetic member 4 is disposed in the first installation groove 6, and the end face of the first installation groove 6 is flush with the end face of the first magnetic member 4. A second installation groove 7 is formed on the end face of the second base 2. The second magnetic member 5 is disposed in the second installation groove 7, and the end face of the second magnetic member 5 is flush with the end face of the second installation groove 7. The first magnetic member 4 and the second magnetic member 5 are coaxial.

[0037] Refer to Figures 2 to 5 As shown, the first magnetic member 4 and the second magnetic member 5 are coaxial, so that the magnetic attraction surfaces are attached to each other, increasing the magnetic attraction area and thus the magnetic attraction force, which can prevent the separation of the first base 1 and the second base 2 to a certain extent.

[0038] A third installation groove 8 is formed on the end face of the first base 1, and a first sealing ring 9 is disposed inside the third installation groove 8.

[0039] A fourth installation groove 10 is further formed on the end face of the first base 1, and a second sealing ring 11 is disposed inside the fourth installation groove 10. The first sealing ring 9 and the second sealing ring 11 are coaxial.

[0040] The arc surface of the first sealing ring 9 and / or the second sealing ring 11 protrudes higher than the end face of the first base 1. The height L of the arc surface of the first sealing ring 9 and / or the second sealing ring 11 higher than the end face of the first base 1 is 0.2 mm to 0.3 mm.

[0041] Refer to Figures 3 to 6 As shown, due to the coaxiality of the first sealing ring 9 and the second sealing ring 11, and the fact that the first sealing ring 9 and the second sealing ring 11 protrude higher than the end face of the first base 1, when the first base 1 and the second base 2 are combined together by the magnetic attraction force between the first magnetic member 4 and the second magnetic member 5, the outer arc surfaces of the first sealing ring 9 and the second sealing ring 11 will undergo a certain deformation, thereby improving the sealing performance between the first base 1 and the second base 2, preventing oxygen from the ventilator or oxygen generator from leaking out through the gap between the first base 1 and the second base 2, and further improving the sealing performance by using two sealing rings, namely the first sealing ring 9 and the second sealing ring 11. In this embodiment, the first sealing ring 9 and the second sealing ring 11 are made of rubber.

[0042] In this embodiment, the O-ring is selected for the shapes of the first sealing ring 9 and the second sealing ring 11. Of course, other shapes of sealing rings, such as V-shaped, rectangular, etc., can also be selected, which are not limited here.

[0043] The height by which the arc surfaces of the first sealing ring 9 and the second sealing ring 11 are higher than the first base 1 can be 0.25 mm. Of course, other heights can also be selected according to needs, which are not limited here.

[0044] The hardness of the first sealing ring 9 and / or the second sealing ring 11 is between 40 and 50 Shore hardness.

[0045] In this embodiment, the Shore hardness of the first sealing ring 9 and the second sealing ring 11 is 45, and other hardness values are also possible, which are not limited here.

[0046] A guiding protrusion 12 is integrally formed on the end surface of the first base 1 facing the second base 2, and a guiding groove 13 adapted to the guiding protrusion 12 is integrally formed on the end surface of the second base 2 facing the first base 1. The guiding protrusion 12 and the guiding groove 13 are conical, and the cone can specifically be a conical shape.

[0047] Refer to Figures 2 to 8 As shown, when the first base 1 and the second base 2 are fitted together, the first base 1 and the second base 2 are gradually coaxially aligned by inserting the guiding protrusion 12 into the guiding groove 13 until they are completely coaxially aligned and the first magnetic member 4 and the second magnetic member 5 are magnetically attracted. Since the combination of the guiding protrusion 12 and the guiding groove 13 can limit the movement in the radial direction between the first base 1 and the second base 2, it can prevent the misalignment of the first magnetic member 4 and the second magnetic member 5, which may reduce the magnetic attraction surface and thus reduce the magnetic attraction force between the first base 1 and the second base 2. Moreover, since it can limit the radial position of the first base 1 and the second base 2, it can prevent the surfaces of the first sealing ring 9 and the second sealing ring 11 from slipping against the end surface of the second base 2 to generate gaps and reduce the sealing performance.

[0048] In this embodiment, the guiding protrusion 12 and the guiding groove 13 can be other shapes besides conical, that is, any shape that can achieve radial position limitation is acceptable, which is not limited here.

[0049] When the first magnetic member 4 is a magnet, the second magnetic member 5 is a metal that can be magnetically attracted to it or can be magnetized by it; or when the second magnetic member 5 is a magnet, the first magnetic member 4 is a magnet that can be magnetically attracted to it or a metal that can be magnetized by it.

[0050] In this embodiment, both the first magnetic member 4 and the second magnetic member 5 are selected as permanent magnets, and the magnetic polarities of their magnetic attraction surfaces are opposite, and the magnetic attraction is achieved by using the characteristic of opposite magnetic poles attracting each other.

[0051] The working process of the present utility model is as follows: When in use, first combine the first base 1 and the second base 2, that is, at this time, the guiding protrusion 12 extends into the guiding groove 13, and the first magnetic attracting member 4 and the second magnetic attracting member 5 come into contact for magnetic attraction to connect the first base 1 and the second base 2. At this time, the two communicating pipes 3 are communicated to form a gas passage, so that the gas from the ventilator or oxygen generator can be transported to the breathing mask through this passage for the user to use. After use, it only needs to overcome the magnetic attraction between the first magnetic attracting member 4 and the second magnetic attracting member 5 to separate the first base 1 and the second base 2.

[0052] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
