Furthermore, the term "according to" should be understood to mean "at least in part based on...", and the term "based on" should be understood to mean "at least in part based on...", unless the context clearly indicates otherwise.

[0068] The following describes the implementation of the embodiments of the present application with reference to the accompanying drawings.

[0069] An embodiment of the present application provides a ventilation pipe structure.

[0070] Figure 1 This is a schematic diagram of the ventilation pipe structure of an embodiment of the present application. Figure 2 2 is another schematic diagram of the ventilation tube structure according to an embodiment of the present application.

[0071] like Figure 1 and Figure 2 As shown, the ventilation pipe structure 10 has a main ventilation pipe 11 and a plurality of branch ventilation pipes respectively connected to the main ventilation pipe 11. The main ventilation pipe 11 is an inclined structure in the second direction Y, and the second direction Y is the length direction of the ventilation pipe structure 10.

[0072] According to the above embodiment, by designing the main ventilation pipe 11 of the ventilation pipe structure 10 to be an inclined structure in the longitudinal direction of the ventilation pipe structure 10, the height difference of the components connected to the branch ventilation pipes can be accommodated, thereby achieving multi-pipe connection.

[0073] It should be noted that, in the above embodiment, Figure 1 and Figure 2 As shown, the main ventilation pipe of the ventilation pipe structure is set to be cylindrical with an open end and a closed end. This application does not limit this. The main ventilation pipe can also be set to be conical. The shape and opening setting of the main ventilation pipe depend on the specific process requirements.

[0074] Figure 3 is a cross-sectional view of the ventilation pipe structure of the embodiment of the present application, showing the other side (ie Figure 1 Observe the ventilation pipe structure on the side close to the observation direction).

[0075] In some embodiments, as Figure 2 and Figure 3 As shown, the plurality of branch ventilation pipes include a first pipe 21, which is located in the first direction X (ie Figure 2 The width direction of the ventilation tube structure 10, or Figure 3 on one side (i.e. Figure 2 on the left side of the Figure 3 At least a portion of the projection of the channel of the first pipeline 21 falls into the interior of the channel of the main ventilation pipeline 11.

[0076] like Figure 1 and Figure 3 As shown, the plurality of branch ventilation pipes further include a second pipe 22, which is located on the other side of the ventilation pipe structure 10 in the first direction X (ie Figure 1 on the right side of the Figure 3 At least a portion of the projection of the channel of the second pipeline 22 falls into the interior of the channel of the main ventilation pipeline 11.

[0077] like Figure 1 and Figure 3 As shown, the axis 21 (a) of the channel of the first pipeline 21 and the axis 22 (a) of the channel of the second pipeline 22 are aligned in the second direction and / or the third direction ( Figure 3 The left, right, up, and down directions shown in the figure do not overlap, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0078] Therefore, by tilting the main ventilation line 11, it is possible to be compatible with the communication area of ​​the first line 21 and the second line 22, increase the communication area of ​​the second line and the first line and the main ventilation line as much as possible, and compensate for the gas flowing between the first line 21 and the second line 22 and the main ventilation line. In addition, the axis of the first line 21 and the second line 22 is set not to overlap in the second direction and / or the third direction, which can avoid direct convection of gas between the first line 21 and the second line 22, and facilitate operations such as measurement of the subsequent gas.

[0079] It should be noted that, in the above embodiment, Figure 3 For example, the projection of the first pipeline 21 falls entirely into the inner side of the channel of the main ventilation pipeline 11, and a part of the projection of the second pipeline 22 falls into the inner side of the channel of the main ventilation pipeline 11. The present application is not limited to this. At least a part of the projection of the first pipeline 21 and the second pipeline 22 falls into the inside of the channel of the main ventilation pipeline 11, and the connecting area between the main ventilation pipeline and the first pipeline and the second pipeline can be increased as much as possible. The present application does not impose any restrictions.

[0080] Figure 4 The embodiment of the present application is from the third direction of the ventilation pipe structure (i.e. Figure 5 on one side (i.e. Figure 3 Schematic diagram of the ventilation pipe structure observed from the lower side of the perspective shown, Figure 5 The embodiment of the present application is the other side of the ventilating pipe structure from the third direction (i.e. Figure 3 Schematic diagram of the ventilation pipe structure observed from the upper side of the perspective shown, Figure 5 The viewing direction and Figure 6 The observation direction is exactly the opposite.

[0081] In some embodiments, as Figure 2 and Figure 4 As shown, the plurality of branch ventilation pipes further include a third pipe 23, which is located in the third direction of the ventilation pipe structure 10 (i.e. Figure 4 in a direction perpendicular to the paper, or Figure 2The height direction of the ventilation tube structure) on one side (i.e. Figure 4 the side closest to the viewing direction, or Figure 2 At least a portion of the projection of the channel of the third line 23 falls into the channel interior of the main ventilation line 11.

[0082] like Figure 1 and Figure 5 As shown, the plurality of branch ventilation pipes further include a fourth pipe 24, which is located in the third direction (i.e. Figure 5 perpendicular to the paper, or Figure 1 the other side (i.e. Figure 5 the side closest to the viewing direction, or Figure 1 ), at least a portion of the projection of the channel of the fourth pipeline 24 falls into the inner side of the channel of the main ventilation pipeline 11.

[0083] Thus, by having at least a portion of the projections of the third pipeline 23 and the fourth pipeline 24 fall into the inner side of the channel of the main ventilation pipeline 11, the ventilation pipe structure 10 can be more reliably fixed on the lower shell, thereby preventing the ventilation pipe structure 10 from tilting during the assembly process. In addition, the contact area between the components connected to the third pipeline 23 and the fourth pipeline 24 and the main ventilation pipeline 11 can be increased as much as possible, thereby improving the accuracy of gas measurement or other operations.

[0084] It should be noted that, in the above embodiment, Figure 4 and Figure 5 For example, the projections of the third pipeline 23 and the fourth pipeline 24 all fall into the inner side of the channel of the main ventilation pipeline 11. The present application is not limited to this. At least a part of the projections of the third pipeline 23 and the fourth pipeline 24 falls into the inner side of the channel of the main ventilation pipeline 11, which can ensure the stability of the ventilation pipe structure 10 and the measurement accuracy. The present application does not impose any restrictions.

[0085] In some embodiments, as Figure 2 and Figure 4 As shown, in the third direction (ie Figure 4 in a direction perpendicular to the paper, or Figure 2 In the up-down direction) on one side (i.e. Figure 4 the side closest to the viewing direction, or Figure 2 A first reinforcing member 41 for reinforcing the fourth pipeline 24 and a second reinforcing member 42 for reinforcing the third pipeline 23 are provided on the lower side thereof.

[0086] like Figure 1 and Figure 5 As shown, in the third direction (ie Figure 5 in a direction perpendicular to the paper, or Figure 2the other side (i.e. Figure 5 the side closest to the viewing direction, or Figure 1 A fourth reinforcement member 44 for reinforcing the fourth pipe 24 and a fifth reinforcement member 45 for reinforcing the third pipe 23 are provided on the upper side thereof.

[0087] Thus, the second reinforcing member 42 and the fifth reinforcing member 45 reinforce the third pipe 23, thereby preventing the third pipe 23 from being deformed due to excessive force or misalignment with other components during blind installation, and allowing the third pipe 23 to more reliably abut against other components. The first reinforcing member 41 and the fourth reinforcing member 44 reinforce the fourth pipe 24, thereby preventing the fourth pipe 24 from being deformed due to excessive force or misalignment with other components during blind installation.

[0088] Figure 6 This is a schematic diagram of the ventilation pipe structure observed from the other side in the first direction according to an embodiment of the present application, showing the observation Figure 3 The situation of the ventilator structure shown in .

[0089] In some embodiments, as Figure 3 and Figure 6 As shown, the first reinforcement component 41 and the fourth pipeline 24 are in the third direction (ie Figure 3 and Figure 6 The fifth reinforcement component 45 and the third pipeline 23 are arranged opposite to each other in the third direction.

[0090] like Figure 4 and Figure 5 As shown, the second reinforcement member 42 is disposed around the third pipe 23 , and the fourth reinforcement member 44 is disposed around the fourth pipe 24 .

[0091] Thus, the second reinforcement member 42 and the fourth reinforcement member 44 surround the sub-ventilation duct, further increasing the strength of the sub-ventilation duct. Furthermore, the first reinforcement member 41 and the fifth reinforcement member 45 are disposed opposite the sub-ventilation duct, respectively. While reinforcing the sub-ventilation duct, the first reinforcement member 41 and the fifth reinforcement member 45 also reinforce the contact surface between the ventilation pipe structure 10 and other components, ensuring a more reliable contact between the ventilation pipe structure 10 and other components.

[0092] It should be noted that, in the above embodiment, Figure 4 and Figure 5For example, the first reinforcing component 41, the second reinforcing component 42 and the fifth reinforcing component 45 are all in the shape of a U-shaped U-shaped component and are arranged around the pipeline, and the fourth reinforcing component 44 is in the shape of a cross. The present application is not limited to this. The first reinforcing component 41, the second reinforcing component 42 and the fifth reinforcing component 45 may not be arranged around the pipeline, and the fourth reinforcing component 44 may not be in the shape of a cross, but may be in other shapes such as a circle. The setting of the shape and position of the reinforcing component depends on the specific process requirements, and it is sufficient to achieve the effect of strengthening the ventilation pipeline. The present application does not impose any restrictions.

[0093] In some embodiments, as Figure 6 As shown, in the third direction (ie Figure 6 On one side (i.e. Figure 6 the lower side) and the other side (i.e. Figure 6 A third reinforcement component 43 and a sixth reinforcement component 46 are respectively provided on the upper side of the second pipeline 22 to reinforce the second pipeline 22.

[0094] In some embodiments, as Figure 6 As shown, the third reinforcement member 43 and the sixth reinforcement member 46 are respectively in the third direction (ie Figure 6 On one side (i.e. Figure 6 the lower side) and the other side (i.e. Figure 6 The upper side of the second pipe 22 is connected.

[0095] Therefore, by respectively arranging the third reinforcement component 43 and the sixth reinforcement component 46 on both sides of the second pipeline 22, the second pipeline 22 can be reinforced while the ventilation pipe structure 10 can be more reliably abutted against other components, thereby avoiding deformation of the ventilation pipe structure due to excessive force or misalignment with other components during blind installation.

[0096] It should be noted that, in the above embodiments, Figure 4 and Figure 5 As shown, the third reinforcement component 43 and the sixth reinforcement component 46 are both cross-shaped and are arranged on both sides of the third direction of the second pipeline. The present application is not limited to this. The third reinforcement component and the sixth reinforcement component can be other shapes such as circular, or can be arranged around the second pipeline. The shape and position of the reinforcement component depend on the specific process requirements and can achieve the effect of strengthening the second pipeline. The present application does not impose any restrictions.

[0097] In some embodiments, the ventilation tube structure 10 is configured in a physiological monitoring device, such as a blood pressure monitor. In the following description, a blood pressure monitor is used as an example of a physiological monitoring device, but this application is not limited to this. The ventilation tube structure 10 of the embodiment of the present application can also be applied to other physiological monitoring devices or medical devices besides blood pressure monitors, as a gas path connecting component for other components of the physiological monitoring device or medical device.

[0098] Figure 7 This is a schematic diagram of a ventilation tube structure installed on a sphygmomanometer according to an embodiment of the present application, showing the other side (i.e. Figure 5 Observe the ventilation tube structure installed on the sphygmomanometer) in the observation direction described in the above.

[0099] In some embodiments, as Figure 7 As shown, the vent tube structure 10 is disposed on the lower housing 33 of the sphygmomanometer 30. The sphygmomanometer 30 also includes a compression pump 31, a vent valve 32, and a sensor 34 disposed on the lower housing 33. The first pipeline 21 connects to the compression pump 31, the second pipeline 22 connects to the vent valve 32, the third pipeline 23 connects to the lower housing 33, and the fourth pipeline 24 connects to the sensor 34. The compression pump 31 can output gas to the main vent line 11, the vent valve 32 can control the gas flow out of the main vent line 11 and the gas discharge rate, and the sensor 34 can measure the gas pressure in the main vent line 11.

[0100] In the above embodiment, four branch ventilation pipes are taken as an example, and each branch ventilation pipe is connected to four components of the sphygmomanometer respectively. This application does not impose any restrictions on this. The number of branch ventilation pipes depends on the needs of the product in which the ventilation pipe structure is set.

[0101] For example, in some embodiments, the ventilation tube structure of the embodiment of the present application is applied to a sphygmomanometer, and the compression pump and ventilation valve of the sphygmomanometer are a combined structure. Therefore, the ventilation tube structure can only be provided with three branch ventilation pipelines, which are respectively connected to the compression pump / ventilation valve, sensor and lower shell of the sphygmomanometer.

[0102] For another example, in some embodiments, the ventilation pipe structure of the embodiments of the present application is applied to other products, and the other products include two or more components that need to be connected to the main ventilation line. In this case, the ventilation pipe structure can be provided with two or more branch ventilation lines to respectively connect with the components of the other products that need to be connected to the main ventilation line.

[0103] Figure 8 is a cross-sectional view of the ventilation tube structure installed on the sphygmomanometer according to an embodiment of the present application, showing the other side (i.e. Figure 3Observe the ventilation tube structure installed on the sphygmomanometer)

[0104] In some embodiments, as Figure 8 As shown, the axis 21 ( a ) of the channel of the first pipeline 21 is located above the axis 22 ( a ) of the channel of the second pipeline 22 .

[0105] Therefore, by setting the first pipeline connected to the compression pump at a higher position, the gas can flow into the entire main ventilation pipeline more conveniently, making the sensor's measurement more accurate. In addition, by setting the second pipeline connected to the ventilation valve at a lower position, the gas can flow out of the connecting valve more smoothly, avoiding overloading the connecting valve.

[0106] In some embodiments, as Figure 8 As shown, the first reinforcement member 41 is connected to the second reinforcement member 42 and the third reinforcement member 43, and the heights of the three reinforcement members are the same. Figure 8 on one side (i.e. Figure 8 The lower side of the ventilating pipe structure 10 is in contact with the lower shell 33 through the first reinforcing member 41, the second reinforcing member 42, and the third reinforcing member 43. Figure 8 The other side (i.e. Figure 8 The upper side of the sphygmomanometer 30 is in contact with the circuit board 35 located inside the sphygmomanometer 30 through the fourth reinforcement component 44, the fifth reinforcement component 45, and the sixth reinforcement component 46.

[0107] Thus, by connecting the reinforcing components on the same side, the overall structure of the vent tube structure can be further strengthened, and the heights of the various reinforcing components can be made the same, so that the vent tube structure can be more securely mounted on the lower shell of the sphygmomanometer, thus preventing the vent tube structure from tilting and moving. By abutting all the reinforcing components on one side of the vent tube structure in the third direction against the lower shell, the strength of the vent tube structure can be increased, allowing the vent tube structure to be blindly installed on the lower shell without deformation. In addition, by abutting all the reinforcing components on the other side of the vent tube structure in the third direction against the circuit board, the circuit board can be securely mounted on the vent tube structure, thus preventing the vent tube structure from deforming during blind installation, causing problems such as air leakage. In addition, stacking the circuit board and the vent tube structure can save space and achieve miniaturization of the product.

[0108] According to the above embodiment, auxiliary reinforcing rib structures are added to each branch ventilation pipe and the main ventilation pipe of the ventilation pipe structure, which can enhance the overall strength of the ventilation pipe structure, realize blind assembly during assembly, and avoid deformation of the ventilation pipe structure during assembly.

[0109] The above only describes the ventilation pipe structure related to the present application. The ventilation pipe structure may also include other components, such as Figure 2 The sealing component 51 shown in the figure for sealing the die hole 50 can be specifically described by referring to the relevant technology, and the description thereof is omitted here.

[0110] It should be noted that in the above embodiment, the ventilation pipe structure and the reinforcement rib structure are both integrally formed using TPV material. The present application is not limited to this. The ventilation pipe structure can also be made of other materials. The choice of material depends on the specific process requirements and can meet the softness and strength required during the blind installation process of the ventilation pipe structure. This application does not impose any restrictions.

[0111] In the above embodiment, taking the sphygmomanometer as an example, the ventilation tube structure is assembled in the sphygmomanometer to achieve miniaturization of the product. The present application is not limited to this. The ventilation tube structure can also be assembled in any required physiological detection equipment or other medical devices, depending on the needs, and the present application does not impose any restrictions.

[0112] Through the above embodiments, the ventilation pipe structure of the present application can accommodate the height difference between the branch ventilation pipes by setting the main ventilation pipe to an inclined structure, thereby realizing multi-pipe connectivity. In addition, by adding auxiliary reinforcement structures to each branch ventilation pipe and the main ventilation pipe of the ventilation pipe structure, the main ventilation pipe can be blindly installed during assembly, and can be stacked with other components in the product, further saving space and reducing the size of the product.

[0113] An embodiment of the present application further provides a physiological detection device, which includes the ventilation tube structure of the aforementioned embodiment. Since the ventilation tube structure has been described in detail in the aforementioned embodiment, it will not be repeated here.

[0114] In the embodiment of the present application, as mentioned above, the physiological detection device may be a sphygmomanometer, but the present application is not limited thereto, and the physiological detection device may also be other products that require a ventilation tube structure.
