Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1-2, fig. 1 is an exploded schematic view of a part of a structure of an air path device according to an embodiment of the present application, where the air path device includes an air path structure. Fig. 2 is a schematic perspective view of the air path device in fig. 1, showing a positional relationship between the correction hole and the air path structure. In one aspect of the present application, an air path device 100 is provided, where the air path device 100 can be applied to inflatable blood pressure measurement devices, such as a blood pressure detector and a dynamic blood pressure electrocardiograph detection device, so as to perform inflation.

Specifically, the air path apparatus 100 in the present application includes a housing 10, and an air path structure 20 and a circuit board 30 mounted in the housing 10. Wherein, the housing 10 is provided with a correction hole 1011. The air path structure 20 and the circuit board 30 are both installed in the housing 10, and the circuit board 30 and the air path structure 20 are assembled with each other. At least a portion of the air path structure 20 is aligned with the correction aperture 1011. That is, a part of the air path structure 20 in the housing 10 can be seen through the correction hole 1011. The shape and position of the correction hole 1011 are not particularly limited as long as the gas path structure 20 can be adjusted through the correction hole 1011.

The air circuit device 100 of the present application, through providing the correction hole 1011 on the housing 10, allows a user or operator to pass through the correction hole 1011, thereby poking the air circuit structure 20 to adjust the position of the air circuit structure 20 to a position assembled with the circuit board 30 to a preset position. That is, when the installation of the air path device 100 is completed and the subsequent detection is performed, whether the installation of the air path structure 20 and the circuit board 30 is in place is checked through the correction hole 1011, and when the installation of the air path structure 20 and the circuit board 30 is not in place is found, the air path structure 20 is manually moved through the correction hole 1011 to correct and reset the air path structure 20 so as to adjust the installation of the air path structure 20 and the circuit board 30 in place, thereby avoiding the problems of high cost and low efficiency caused by repeated disassembly and assembly of the circuit board 30 only when the installation of the air path structure 20 and the circuit board 30 is not in place in the prior art.

It is understood that the circuit board 30 may be a blood pressure parameter board, and the air pressure data of the air circuit structure 20 during blood pressure detection is stored in the memory of the circuit board 30. In other embodiments, the circuit board 30 may also include a plurality of integrated modules, such as a blood pressure parameter board and a main board, so that not only blood pressure data can be maintained, but also adjustment and control can be performed through the main board as required. Alternatively, when used in a blood pressure detecting and electrocardiographic detecting integrated detector, the circuit board 30 integrates a blood pressure parameter board, an electrocardiographic parameter board, a main board, and the like, so that blood pressure detection and electrocardiographic detection can be performed simultaneously, and blood pressure detection data and electrocardiographic detection data can be stored, which will be described in detail below.

In some embodiments, with reference to fig. 3, fig. 3 is a schematic structural diagram of the circuit board of fig. 1. The air circuit structure 20 may include an interface 2121 and the circuit board 30 is provided with a detector 301. The assembly between the circuit board 30 and the air circuit structure 20 may be accomplished by a connection between the detector 301 on the circuit board 30 and the interface 2121 on the air circuit structure 20. The housing 10 has a cavity 103 formed therein, and the air path structure 20 and the circuit board 30 are both mounted in the cavity 103. The calibration holes 1011 are in communication with the receiving cavity 103, and at least a portion of the calibration holes 1011 are aligned with the portion of the air path structure 20 where the interface 2121 is provided. Therefore, when the air path structure 20 and the circuit board 30 are not in place, the air path structure 20 can be manually moved through the correction hole 1011 to correct and reset the air path structure 20, so as to adjust the air path structure 20 to be in place with the circuit board 30. It can be appreciated that, since the calibration holes 1011 are aligned with the positions of the air path structure 20 where the interfaces 2121 are provided, when the air path structure 20 is adjusted, the positions of the air path structure 20 where the interfaces 2121 are provided are directly moved, which is labor-saving and accurate.

In addition, the circuit board 30 can also collect information through the detector 301 to regulate and control the inflation process of the air channel structure 20. The information collected by the detector 301 may include flow rate information of the air flow and air pressure information in the air path structure.

In a specific embodiment, the housing 10 may be a rigid material such as a hard plastic. The housing 10 is a generally rectangular box, and the receiving cavity 103 includes a bottom wall 101 and side walls 102. The correction hole 1011 is formed in the bottom wall 101, and the correction hole 1011 penetrates the bottom wall 101 of the housing 10 and communicates with the accommodation chamber 103.

The side wall 102 is also provided with an air tap connection port 1021, and the air tap connection port 1021 is used for being connected with external equipment to provide required air pressure for the external equipment.

Wherein, a plurality of clamping structures are further protruding on the bottom wall 101, and the plurality of clamping structures are used for clamping the air path structure 20. It is understood that the air path structure 20 may be connected by screw connection, riveting, or the like, in addition to being clamped on the bottom wall 101.

Referring to fig. 4, fig. 4 is an exploded schematic view of the air path structure in fig. 1. In one embodiment, the air path structure 20 may include an air pipe 21, at least one air release valve 22 connected to the air pipe 21, an air tap 23, and an air inflation pump 24. That is, the air pipe 21 is used for communicating the air release valve 22, the air tap 23 and the air inflation pump 24 to form a controllable inflation channel. Wherein the air release valve 22 can be opened to release air as required during or at the end of inflation. The air tube 21 may be made of a material having high elasticity or a material having high rigidity.

To fully illustrate the specific structure of the air circuit structure 20, further description will be provided below in connection with some specific embodiments.

With reference to fig. 5, fig. 5 is a schematic view of the tracheal structure of fig. 4. In one particular embodiment, airway 21 includes a main airway 211 and a sensing manifold 212 coupled to and in communication with main airway 211. The main air passage 211 is installed in the accommodating cavity 103, and the main air passage 211 can move in the accommodating cavity 103 after being stressed. Interface 2121 is provided on test manifold 212. And in particular, the portion of main gas path 211 facing away from sensing branch 212, i.e., the portion facing away from port 2121, is aligned with at least a portion of correction aperture 1011. Since the detecting branch pipe 212 is connected and linked with the main air passage 211, when the air passage structure 20 is adjusted, the main air passage 211 is moved directly through the correction hole 1011, so that the detecting branch pipe 212 and the interface 2121 arranged thereon are driven to move to adjust the interface 2121 to be in place with the detector 301 of the circuit board 30. Similarly, the portion of the main air passage 211 facing away from the detecting branch 212, i.e., the portion facing away from the port 2121, is aligned with at least a portion of the correction hole 1011, so that the portion of the port 2121 is directly moved when the main air passage 211 is adjusted, which is labor-saving and accurate.

Specifically, the interface 2121 is a mounting hole disposed on the detecting branch pipe 212 and far from one end of the main air channel 211, and the diameter of the mounting hole is larger than the inner diameter of the detecting branch pipe 212, so as to form a step on the inner wall of the detecting branch pipe 212 far from one end of the main air channel 211, so that the detector 301 is convenient to be mounted and positioned.

More specifically, the projection of the interface 2121 on the bottom wall 101 partially coincides with the correction hole 1011, or the projection of the interface 2121 on the bottom wall 101 is located within the correction hole 1011. It will be appreciated that when the detector 301 on the circuit board 30 is mated with the interface 2121, the circuit board 30 will partially cover the air path structure 20 and completely cover the interface 2121. Therefore, when the circuit board 30 is mounted or the subsequent detection is performed, the matching between the detector 301 and the interface 2121 is not convenient to adjust due to the shielding of the circuit board 30, the air pipe 21 can be corrected and reset by manually moving the air pipe 21 through the correction hole 1011, so as to adjust the interface 2121 on the air pipe 21 to be mounted in place with the detector 301, thereby avoiding the problems of high cost and low efficiency caused by repeated dismounting of the circuit board 30 only when the interface 2121 and the detector 301 are not mounted in place in the prior art.

The specific position of the correction hole 1011 on the housing 10 may be such that the correction hole 1011 is partially aligned with the air path structure 20. The correction hole 1011 may be provided at any position partially aligned with the air pipe 21, or may be provided at any position partially aligned with the inflation pump 24, or the like. Because the components of the air path structure 20 are all connected together and form a whole, after an acting force is applied to any component of the air path structure, the adjustment and the resetting of the connection between the interface 2121 and the detector 301 can be realized due to the interaction of the forces.

In one particular embodiment, the air release valve 22 is connected to the main air passage 211, with the air release valve 22 being opened or closed as desired. With continued reference to FIG. 4, in some embodiments, there are two air release valves 22, one air release valve 22 being the primary air release valve 221 and one air release valve 22 being the backup air release valve 222, the backup air release valve 222 may be activated to increase the air release rate when it is desired to increase the air release rate. More specifically, in some embodiments, a connection branch 213 is further extended from the main air passage 211, and the air release valve 22 is connected to the connection branch 213, where the connection branch 213 communicates the main air passage 211 with the air release valve 22.

It will be appreciated that when there are two air release valves 22, there are two corresponding connecting branches 213. I.e. a connecting branch 213 is connected to a release valve 22.

Specifically, in some embodiments, either the detection branch 212 or the connection branch 213 is connected perpendicular to the main air path 211. More specifically, the detecting branch pipes 212 and the connecting branch pipes 213 are each formed by extending the main air passage 211 vertically, and the detecting branch pipes 212 and the connecting branch pipes 213 are each communicated and linked by the main air passage 211. Wherein, to avoid interference, in some specific embodiments, the main airway 211 and the connecting branches 213 are coplanar, and the plurality of connecting branches 213 are located on the same side of the main airway 211. The detecting branch pipe 212 is perpendicular to a plane formed by the main air passage 211 and the connecting branch pipe 213. That is, the axis of each connecting branch 213 is perpendicular to the axis of the main air passage 211, and the axis of the detecting branch 212 is perpendicular to a plane formed by the axis of the connecting branch 213 and the axis of the main air passage 211.

The coplanar main air passage 211 and the connecting branch 213 are all clamped in a plurality of clamping structures protruding from the bottom wall 101, and the main air passage 211 and the connecting branch 213 clamped in the bottom wall 101 can move in the accommodating cavity 103 after being stressed.

In a specific embodiment, the air pump 24 is clamped in a plurality of clamping structures protruding from the bottom wall 101, and the air pump 24 is disposed on a side of the main air channel 211 away from the connecting branch 213.

The protruding direction of the air inlet pipe 242 and the air outlet pipe 241 is parallel to the main air passage 211, and the air outlet pipe 241 is communicated with one port of the main air passage 211.

More specifically, the axis of the inflation pump 24 is parallel to the axis of the main air passage 211, and the axis of the inflation pump 24 is perpendicular to the axis of the interface 2121. The air outlet pipe 241 is disposed at an end face of the inflation air pump 24, and the air outlet pipe 241 is disposed to extend in a direction parallel to the main air passage 211.

In one embodiment, the number of detectors 301 on the circuit board 30 of the present application may be two, one detector 301 being a pressure sensor and one detector 301 being an air flow sensor.
