Description

Technical Field

[0001] The utility model relates to the technical field of ventilation therapy, in particular to a connection component of a breathing device and a breathing device. Background Art

[0002] A respiratory device, such as a ventilator, is an assisted respiratory therapy device with artificial ventilation function. The respiratory gas it produces is provided to a breathing mask worn on the user's face through a breathing tube for use. It effectively improves the patient's respiratory function by increasing the patient's lung ventilation volume. It is now widely used in the treatment of respiratory diseases such as respiratory failure, respiratory insufficiency, sleep apnea syndrome, chronic obstructive pulmonary disease, and can play an important role in assisting the patient's breathing, saving and prolonging the patient's life.

[0003] A ventilator generally includes a main unit, a water reservoir and a ventilation line. The breathing gas flows through the water reservoir and the ventilation line to be humidified and heated before being delivered to the user to obtain a good breathing experience, thereby improving the compliance of wearing a breathing mask. The ventilation line of a common ventilator is connected to the main unit through a socket on one side of the main unit. When the ventilator is placed in different use positions, some positions are not conducive to the ventilation line being connected to the breathing mask in a relaxed and soft posture, making the ventilator inconvenient to use.

[0045] The utility model will be further described below in conjunction with the accompanying drawings.

[0046] like Figure 1-Figure 5 As shown, the utility model provides a connection assembly for a respiratory device, comprising a host connector 1 for connecting to a host 100 of the respiratory device, a ventilation pipeline connector 3 for connecting to a ventilation pipeline 200 of the respiratory device, and an adapter 2, wherein the adapter 2 comprises an adapter body 20. The ventilation pipeline 200 may be an ordinary pipeline without a heating function or a heating pipeline with an electric heating wire.

[0047] The host connector 1 is configured to be connected to the ventilation line connector 3 through the adapter body 20 , and after the ventilation line connector 3 and the adapter body 20 rotate by a preset angle, the host connector 1 is connected to the ventilation line connector 3 again through the adapter body 20 .

[0048] Example 1

[0049] In the present embodiment 1, the ventilation pipeline 200 is a heating pipeline, and thus the ventilation pipeline connector 3 is a heating pipeline connector, which has the ability to draw electricity from the host 100 .

[0050] In this embodiment 1, the host connector 1 can be electrically connected to the ventilation pipe connector 3 through the adapter body 20, and the host connector 1 can be electrically connected to the ventilation pipe connector 3 again through the adapter body 20 after the adapter body 20 and the ventilation pipe connector 3 are rotated relative to the host connector 1 by a preset angle. Figure 1 and Figure 2 FIG. 1 shows an embodiment in which the host connector 1 is connected to the ventilation pipe connector 3 via the adapter 2. Figure 1 and Figure 2 One end of the ventilation line connector 3 is connected to the ventilation line 200 of the breathing device, and the other end thereof is connected to the adapter body 20, so that the host connector 1 can be electrically connected to the ventilation line connector 3 through the adapter body 20. Generally, the host connector 1 is arranged on the host 100, and the ventilation line connector 3 is fixedly connected to one end of the ventilation line 200.

[0051] like Figure 1 As shown, the ventilation pipe connector 3 and the adapter 2 are in their first orientation position, that is, the ventilation pipe connector 3 and the second main body 22 below are both facing the right side of the breathing device (host 100), and the ventilation pipe 200 connected to the ventilation pipe connector 3 extends toward the right side of the breathing device (host 100). Figure 2As shown, the ventilation pipe connector 3 and the adapter 2 can be rotated by a preset angle (for example, 180°). After the preset angle is rotated, the ventilation pipe connector 3 and the adapter 2 are in their second orientation position, that is, the ventilation pipe connector 3 and the second body 22 are both facing the left side of the breathing device (host 100), and the ventilation pipe 200 connected to the ventilation pipe connector 3 extends toward the left side of the breathing device (host 100). When the ventilation pipe connector 3 is in its second orientation position, the host connector 1 can be electrically connected to the ventilation pipe connector 3 again through the adapter body 20 of the adapter 2.

[0052] Specifically, Figure 3 As shown, the host connector 1 includes a host connector cover plate 12, a plurality of electrical connector male heads 11, a plurality of first connectors 13 and a host connector pipe 14 on the host connector cover plate 12. The host connector pipe 14 can be arranged at the middle position of the host connector cover plate 12, so the axis of the host connector pipe 14 can be regarded as the rotational symmetry axis of the host connector 1.

[0053] like Figure 3 As shown, the host connector cover plate 12 is provided with a plurality of electrical connector male heads 11 symmetrically arranged about the rotational symmetry center of the host connector 1 (i.e., the middle position of the host connector cover plate 12), and the preset angle is the rotation angle between the plurality of electrical connector male heads 11 or an integer multiple of the rotation angle between the plurality of electrical connector male heads 11. The plurality of electrical connector male heads 11 are used to be plugged and connected with the adapter body 20 and electrically connected. Figure 3 As shown, two electrical connector male heads 11 are arranged on the host connector cover plate 12. In this embodiment, the preset angle is 180°, that is, the two electrical connector male heads 11 are respectively close to the upper and lower parts of the host connector cover plate 12, and are symmetrically arranged about the middle position of the host connector cover plate 12.

[0054] The adapter body 20 includes a first body 21 and a second body 22 that are electrically connected, wherein the first body 21 is used to be electrically connected to and fixedly connected with the host connector 1, and the second body 22 is used to be electrically connected to and fixedly connected with the ventilation pipe connector 3. Therefore, the host connector 1 can be electrically connected to the ventilation pipe connector 3 through the adapter body 20.

[0055] There is an angle between the rotational symmetry axis of the first body 21 and the rotational symmetry axis of the second body 22, that is, a rotation angle structure is formed between the two. The angle may be less than 180°, for example Figure 1 As shown, the angle is 90°. By providing the adapter body 20 with an angle, the ventilation line connector 3 and the host connector 1 on the host 100 can be placed at an angle, so that the ventilation line 200 connected to the ventilation line connector 3 is connected to the right side relative to the host 100 in a relaxed and flexible posture, so that the user can obtain a comfortable use position.

[0056] like Figure 3 and Figure 4 As shown, the first body 21 is provided with an intermediate electrical connector 23 and a plurality of first intermediate connectors, and the intermediate electrical connector 23 is plugged and connected to any one of the plurality of electrical connectors 11 of the host connector 1 and is electrically connected. The electrical connector 11 includes an electrical socket, and the intermediate electrical connector 23 includes an electrical plug.

[0057] The electrical connector male connector 11 includes an electrical socket, and the intermediate electrical connector female connector 23 includes an electrical plug (eg, the intermediate electrical connector plug 231 ); or the electrical connector male connector 11 includes an electrical plug, and the intermediate electrical connector female connector 23 includes an electrical socket, and the two can achieve electrical connection.

[0058] More specifically, the electrical connector 11 near the upper part of the host connector cover 12 has a first host socket 111, and the electrical connector 11 near the lower part of the host connector cover 12 has a second host socket 112, wherein either the first host socket 111 or the second host socket 112 can be plugged and connected to the intermediate electrical connection plug 231 provided on the first body 21 and electrically connected.

[0059] Therefore, when the intermediate electrical connection plug 231 provided on the first body 21 is plugged and connected with the first host socket 111 and electrically connected, the first body 21 and the second body 22 are in their first orientation positions, and the ventilation pipe connector 3 connected to the second body 22 is also in its first orientation position, that is, the ventilation pipe 200 connected to the ventilation pipe connector 3 faces the right side of the breathing device (host 100). When the second body 22 and the ventilation pipe connector 3 remain connected, the first body 21 is detached from the host connector cover 12, and the adapter body 20 and the ventilation pipe connector 3 are rotated 180°, the intermediate electrical connection plug 231 provided on the first body 21 can still be plugged and connected with the second host socket 112 and electrically connected, and the ventilation pipe 200 connected to the ventilation pipe connector 3 faces the left side of the breathing device (host 100) (such as Figure 2 As shown), the ventilation line 200 connected to the ventilation line connector 3 can be relatively Figure 1 The right side position in the main unit 100 is adjusted to the left side position relative to the main unit 100, thereby completing the left-right direction exchange of the ventilation line 200, facing the direction desired by the user, and ensuring that it can be electrically connected to the main unit 100 to draw power from the main unit 100, thereby improving the convenience and comfort of the user. Regardless of which side (for example, the left or right side) the ventilation line connector 3 and the ventilation line 200 connected to the ventilation line connector 3 are connected to relative to the main unit 100, the main unit connector 1 can be electrically connected to the ventilation line connector 3 through the adapter body 20.

[0060] It is understandable that the preset angle can be other angles. For example, more electrical connectors 11 can be provided on the host connector cover 12, and the rotation angle between each electrical connector 11 will be less than 180°. For example, if three electrical connectors 11 are provided, the rotation angle between each electrical connector 11 is 120°; if four electrical connectors 11 are provided, the rotation angle between each electrical connector 11 is 90°. It is understandable that if n electrical connectors 11 are provided, the rotation angle between each electrical connector 11 is 360° / n, where n is a positive integer greater than or equal to 2. Since the vent pipe connector 3 can be connected to the host connector 1 through the adapter body 20, for example, when three electrical connector males are provided on the host connector, and the angle between adjacent electrical connector males is 60°, the vent pipe connector 3 and the adapter body 20 remain connected, and the two can be rotated at a preset angle of 60° relative to the host connector 1 (i.e., 1 times the angle between adjacent electrical connector males), or the two can be rotated at a preset angle of 120° relative to the host connector 1 (i.e., 2 times the angle between adjacent electrical connector males), or the two can be rotated at a preset angle of 180° relative to the host connector 1 (i.e., 3 times the angle between adjacent electrical connector males), etc. Therefore, the vent pipe connector 3 can be rotated at a preset angle of an integer multiple of the angle between adjacent electrical connector males relative to the host connector 1. By using different numbers of electrical connector males 11, the orientation of the adapter body 20 and the vent pipe connector 3 can be adjusted more finely to meet the use requirements.

[0061] Furthermore, a plurality of first intermediate connecting parts are also provided on the first body 21, and the plurality of first intermediate connecting parts are fixedly connected to the corresponding first connecting parts 13. The plurality of first intermediate connecting parts are symmetrically arranged about the rotational symmetry center of the first body 21, and the rotational symmetry center of the first body 21 and the rotational symmetry center of the host connector 1 are on the same rotational symmetry axis; the number of the first intermediate connecting parts is the same as the number of the first connecting parts 13, and the rotation angle between the plurality of first intermediate connecting parts is the same as the rotation angle between the plurality of first connecting parts 13.

[0062] Optionally, the first intermediate connection portion and the first connection portion 13 may be fixedly connected by a snap connection. For example, the first connection portion 13 may be a first host card slot 131 and a second host card slot 132 respectively located on the host connector cover plate 12, and the rotation angle between the two is 180°. The first intermediate connection portion may be a first intermediate buckle 211 and a second intermediate buckle 212 respectively located on the left and right sides of the first body 21, and the rotation angle between the two is 180°.

[0063] Therefore, if Figure 3As shown, when the middle electrical connection plug 231 of the first body 21 is plugged in and electrically connected with the first host socket 111, the first middle clip 211 is plugged in and connected with the first host slot 131, and the second middle clip 212 is plugged in and connected with the second host slot 132, thereby ensuring a stable electrical connection between the first body 21 and the host connector 1. Furthermore, after the adapter body 20 and the ventilation pipe connector 3 are rotated by a preset angle, the intermediate electrical connection plug 231 of the first body 21 is plugged and connected with the second host socket 112 and electrically connected, and the first intermediate buckle 211 is engaged and connected with the second host slot 132, and the second intermediate buckle 212 is engaged and connected with the first host slot 131, so that a stable electrical connection between the first body 21 and the ventilation pipe connector 3 and the host connector 1 can still be ensured, so that the ventilation pipe 200 connected to the ventilation pipe connector 3 can change direction relative to the last connection position (that is, the first intermediate buckle 211 is engaged and connected with the first host slot 131, and the second intermediate buckle 212 is engaged and connected with the second host slot 132), toward the direction desired by the user, and ensure that it can be electrically connected with the host 100 to draw power from the host 100.

[0064] like Figure 3 As shown, the outer surfaces of the first middle buckle 211 and the second middle buckle 212 are both provided with an adapter anti-slip portion 213, which is used to provide friction when grasping the adapter body 20, so that the adapter body 20 can be more easily plugged and unplugged with the host connector 1.

[0065] In addition, the first connection portion 13 may be a buckle, and the first intermediate connection portion may be a slot, and the two may be able to cooperate with each other.

[0066] It can be understood that the first connection portion 13 on the host connector cover 12 and the electrical connector 11 are spaced apart in the circumferential direction of the host connector cover 12 to avoid interference.

[0067] Optionally, the first connection part 13 of the host connector 1 and the first intermediate connection part of the first body 21 can also be fixedly connected by means of threaded connection or magnetic connection, and screws, magnetic parts and other components for achieving fixed connection can be correspondingly arranged on the host connector cover 12 and the first intermediate connection part.

[0068] In addition, the rotation angles of the first connection portion 13 and the first intermediate connection portion need to be the same as the preset angles described above, so as to ensure that the first body 21 and the ventilation pipe connector 3 can be connected accordingly after rotating through the preset angles. Therefore, the number of the first connection portion 13 and the first intermediate connection portion can be set according to the preset angles.

[0069] It should be noted that the "rotation angle" mentioned herein refers to the angle between the rotation line connecting a point and the center when the component rotates, and the line connecting the corresponding point of the point after rotation and the rotation center. For example, the rotation angle between the first connecting parts 13 refers to the angle between the rotation line connecting the first connecting part 13 and the rotational symmetry center, and the line connecting the corresponding point of the first connecting part 13 after rotation and the rotation center, which is related to the number of the components. Specifically, the rotation angle = 360° / n, where n is the number of components, for example, it is a positive integer greater than or equal to 2.

[0070] Please continue to see Figure 3 and Figure 4 The second body 22 is used for being electrically connected and fixedly connected to the ventilation pipe joint 3. The second body 22 is provided with an intermediate electrical connection male head 24, which is electrically connected to the intermediate electrical connection female head 23 on the first body 21 through a wire.

[0071] The ventilation pipe joint 3 is provided with an electrical connection female head 31, which may be, for example, an electrical connection plug, and the intermediate electrical connection male head 24 may be, for example, an intermediate electrical connection socket 241 (such as Figure 4 As shown in the figure, it is plugged and connected with the electrical connection female head 31 and electrically connected. Since the ventilation pipe joint 3 rotates together with the second body 22 and the first body 21, the second body 22 is provided with an intermediate electrical connection male head 24 corresponding to the electrical connection female head 31 of the ventilation pipe joint 3.

[0072] Or the intermediate electrical connector 24 may include an electrical plug, for example, and the electrical connector 31 may include an electrical socket, and the two may be able to cooperate with each other.

[0073] It can be understood that the middle electrical connector 24 of the second body 22 can adopt the same structural form as the electrical connector 11 of the host connector 1, and the middle electrical connector 23 of the first body 21 can also adopt the same structural form as the electrical connector 31 of the ventilation pipe connector 3.

[0074] Please continue to see Figure 3 and Figure 4 The second body 22 is also provided with a plurality of second intermediate connecting parts symmetrically arranged about the rotational symmetry center of the second body 22, and the ventilation pipe joint 3 is also provided with a plurality of second connecting parts 32, and each second connecting part 32 is fixedly connected to the corresponding second intermediate connecting part.

[0075] The plurality of second connection parts 32 are symmetrically arranged about the rotational symmetry center of the ventilation pipe joint 3, and the rotational symmetry center of the ventilation pipe joint 3 is on the same rotational symmetry axis as the rotational symmetry center of the second body 22. The number of the second connection parts 32 is the same as the number of the second intermediate connection parts, and the rotation angle between the plurality of second connection parts 32 is the same as the rotation angle of the plurality of second intermediate connection parts.

[0076] Optionally, the second connection portion 32 and the second intermediate connection portion can be fixedly connected by a snap connection. For example, the second intermediate connection portion can be a first intermediate slot 221 and a second intermediate slot 222 respectively located on the second body 22, and the rotation angle between the two is 180°. The second connection portion 32 can be a first ventilation line buckle 321 and a second ventilation line buckle 322 respectively located on the left and right sides of the ventilation line connector 3, and the rotation angle between the two is 180°.

[0077] Therefore, when the electrical connection female head 31 of the ventilation pipe connector 3 is plugged into and electrically connected with the intermediate electrical connection socket 241 of the second main body 22, the first ventilation pipe clip 321 is snap-connected with the first intermediate slot 221, and the second ventilation pipe clip 322 is snap-connected with the second intermediate slot 222, thereby ensuring a stable electrical connection between the ventilation pipe connector 3 and the second main body 22.

[0078] like Figure 3 As shown, a ventilation pipeline anti-slip portion 323 is provided on the outer surfaces of the first ventilation pipeline buckle 321 and the second ventilation pipeline buckle 322, which is used to provide friction when grasping the ventilation pipeline connector 3, so that the ventilation pipeline connector 3 can be more easily plugged and unplugged with the host connector 1.

[0079] In addition, the second intermediate connection portion may be a buckle, and the second connection portion 32 may be a slot, and the two may be able to cooperate with each other.

[0080] The vent pipe connector 3 can be connected to the adapter body 20, and the two can be connected to the host connector 1 after forming a whole, and can be electrically connected and fixedly connected to the host connector 1 again after being rotated by a certain angle relative to the host connector 1. The first intermediate slot 221 and the second intermediate slot 222 can respectively adopt the same structural form as the first host slot 131 and the second host slot 132, and the first intermediate buckle 211 and the second intermediate buckle 212 can respectively adopt the same structural form as the first vent pipe buckle 321 and the second vent pipe buckle 322.

[0081] like Figure 3 and Figure 5 As shown, the adapter 2 further includes a housing 25, which is disposed outside the adapter body 20 and covers the adapter body 20. Figure 1 and Figure 2As shown, the housing 25 can also cover a part of the host connector 1 and a part of the ventilation pipe connector 3. The housing 25 can be, for example, a split structure, which can include an upper housing shell 251 and a lower housing shell 252, which are snap-fitted and connected, so that the housing 25 is detachably connected to the adapter body 20, which is convenient for connecting the adapter body 20 with the host connector 1 and the ventilation pipe connector 3, and can also encapsulate the adapter body 20 inside it to improve the overall aesthetics.

[0082] like Figure 3 As shown, corresponding avoidance grooves 253 are provided on the upper shell 251 and the lower shell 252 of the outer shell, wherein the avoidance groove 253 can pass through the first middle buckle 211 (the second middle buckle 212), so that the first middle buckle 211 and the second middle buckle 212 are located outside the outer shell 25. When disassembling, the first middle buckle 211 and the second middle buckle 212 can be directly grasped for disassembly without disassembling the outer shell 25 first.

[0083] like Figure 4 As shown, a receiving groove 254 is also provided on the upper shell 251 and the lower shell 252 of the housing. Since the middle electrical connector 24 protrudes from the outside of the second body 22, the receiving groove 254 can accommodate the middle electrical connector 24 therein.

[0084] Example 2

[0085] Based on the above-mentioned embodiment 1, the present invention provides a modified embodiment 2.

[0086] In Embodiment 2, different from Embodiment 1, the ventilation pipe 200 is a common pipe without an electric heating wire. In other words, the ventilation pipe 200 does not need to be powered by the host 100, and the adapter 2 does not need to be powered by the host 100 either.

[0087] Therefore, in this embodiment 2, the host connector 1 can be connected to the ventilation pipe connector 3 through the adapter body 20 (for example, gas communication), and the host connector 1 can be connected to the ventilation pipe connector 3 again through the adapter body 20 (for example, gas communication) after the adapter body 20 is rotated by a preset angle relative to the host connector 1 while the adapter body 20 and the ventilation pipe connector 3 remain connected.

[0088] Therefore, it can be understood that in this embodiment 2, the main unit connector cover plate 12 of the main unit connector 1 may not be provided with the electrical connection male head 11, and accordingly, the first body 21 may not be provided with the intermediate electrical connection female head 23, the second body 22 may not be provided with the intermediate electrical connection male head 24, and the ventilation pipe connector 3 may not be provided with the electrical connection female head 31. In other words, the main unit connector 1 and the first body 21, and the second body 22 and the ventilation pipe connector 3 are connected only by mechanical connection.

[0089] The similarities between this embodiment 2 and the above-mentioned embodiment 1 will not be repeated again.

[0090] Example 3

[0091] Based on the above-mentioned embodiment 1, the present invention provides a modified embodiment 3.

[0092] In Embodiment 3, different from Embodiment 1, the ventilation pipe 200 is a common pipe without an electric heating wire. That is, the ventilation pipe 200 does not need to be powered by the host 100. However, the adapter 2 can still be powered by the host 100, that is, in Embodiment 3, an electrical connector male head 11 is provided on the host connector cover plate 12 of the host connector 1, an intermediate electrical connector female head 23 is provided on the first body 21, and an intermediate electrical connector male head 24 is provided on the second body 22, but the ventilation pipe connector 3 may not be provided with an electrical connector female head 31.

[0093] That is to say, in this embodiment 3, the adapter body 20 may be electrically connected to the host connector 1, but the ventilation pipe connector 3 may not be electrically connected to the adapter body 20, but only mechanically connected to the adapter body 2.

[0094] The similarities between this embodiment 3 and the above-mentioned embodiment 1 will not be repeated again.
