Description

Technical Field

[0001] The utility model relates to the field of signal acquisition, in particular to a signal detection device. Background Art

[0002] At present, wearable signal detection devices can collect physiological signals generated by the human body, such as electrocardiogram signals, in real time, and can store, process and transmit the collected signals.

[0003] A wearable signal detection device usually includes a host structure and patch electrodes connected to each other. The patch electrodes can collect signals from the object to be detected. The host structure includes a signal processing module. The collection electrode sends the collected signals to the signal processing module, and the signal processing module processes the collected signals to obtain detection data.

[0004] Existing signal detection devices, such as electrocardiographs, are all semi-disposable structures, which means that the patch electrodes are disposable and the host structure is reusable. For a new patch electrode, the signal detection device can be turned on by plugging the available host structure with the new patch electrode. However, the semi-disposable structure will bring problems of convenience and information security because the host structure will be reused.

[0005] The fully disposable structure can solve the above problems. The fully disposable structure means that both the patch electrode and the host structure are disposable. However, the existing fully disposable structure will separate the patch electrode connector from the host structure. When the user uses it, the connector is inserted into the host structure to achieve electrical connection. However, this method is not reliable. The exposed connector is easily damaged. When the user plugs it in, it is easy to cause startup failure due to improper operation. Utility Model Content

In addition, the method implementation may include additional steps and / or omit the steps shown. The scope of the present utility model is not limited in this respect.

[0030] The term "including" and its variations used in this document are open inclusions, that is, "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the description below. It should be noted that the concepts of "first", "second", etc. mentioned in the present utility model are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0031] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 1 to 4 The embodiment of the utility model provides a signal detection device, which includes a host structure 1, and a patch electrode 2 connected to the host structure 1 in a non-releasable manner, and the patch electrode 2 is configured to be attached to an object to be detected to collect electrical signals. The host structure 1 includes a shell 11, a battery 12 located in the shell 11, and a signal processing module 13, and the signal processing module 13 is configured to process the electrical signal collected by the patch electrode 2 to obtain detection data. The host structure 1 also includes an isolation tab 14 extending from the inside of the shell to the outside of the shell, and the isolation tab 14 is configured to electrically isolate the battery 12 and the signal processing module 13 before being pulled out.

[0034] Among them, the host structure and the patch electrode are connected "in a non-releasable manner", which means that the connection between the host structure and the patch electrode will not be separated without intentional damage by humans. In other words, the signal detection device provided by the utility model is a fully disposable structure, not a semi-disposable structure. For the fully disposable structure, the host structure and the patch electrode are not connected in a "releasable manner" such as "plugging" or "snapping". In the embodiment of the utility model, the "non-releasable manner" can be specifically achieved in the following manner: the host structure and the patch electrode are physically connected together by adhesive, and the patch electrode includes a patch attached to the object to be detected and an electronic circuit for collecting electrical signals, and the electronic circuit includes a flexible circuit board, and the flexible circuit board passes through the patch and the shell from the side of the patch close to the object to be detected, and is electrically connected to the signal processing module in the shell.

[0035] The signal detection device provided by the present embodiment of the invention has a host structure and a patch electrode electrically connected in a non-releasable manner, indicating that the signal detection device is a fully disposable structure. In order to keep the signal detection device in a shutdown state when leaving the factory and to conveniently turn it on when the user uses it, the present invention provides an isolation pull tab in the fully disposable signal detection device. The isolation pull tab can electrically isolate the battery and the signal processing module. When in use, the user pulls the isolation pull tab out from the host structure to allow the battery to supply power to the signal processing module, and the signal detection device is started.

[0036] Continue to see Figure 3 The battery 12 includes a first electrode 12a and a second electrode 12b; the signal processing module 13 includes an electrical connection terminal 131a, and the electrical connection terminal 131a includes a first contact (not shown) and a second contact (not shown); the first electrode 12a and the second electrode 12b are electrically connected to the first contact and the second contact respectively through a first connector 16 and a second connector 17. The battery may be a button battery, the first electrode 12a may be one of a positive electrode and a negative electrode, and the second electrode 12b may be the other of the positive electrode and the negative electrode.

[0037] It is understandable that the present embodiment does not limit the position of the isolation tab, as long as the isolation tab is located at a position that can cut off the signal connection between the battery and the signal processing module. For example, the isolation tab can be located between the first electrode and the first connector, or the isolation tab can be located between the second electrode and the second connector, or the isolation tab can be located between the first connector and the first contact, or the isolation tab can be located between the second connector and the second contact.

[0038] Continue to see Figures 1 to 4The housing 11 includes a first housing portion 11 a and a second housing portion 11 b that cooperate with each other. The first housing portion 11 a and the second housing portion 11 b cooperate with each other to form a cavity that can accommodate the battery 12 and the signal processing module 13 .

[0039] In one embodiment, the isolation tab 14 can extend from the inside of the housing 11 through the mating surface of the first housing portion 11a and the second housing portion 11b to the outside of the housing 11. The provision of the isolation tab in this embodiment has the advantages of convenience and simplicity, and can simplify the assembly process of the signal detection device.

[0040] In another embodiment, the edge of the second housing portion 11b has a through hole 11d, and the isolation pull tab 14 extends from the housing 11 through the through hole 11d to the outside of the housing 11. In a more specific embodiment, a sealing block 11e is further included, and the sealing block 11e is located in the through hole.

[0041] In this embodiment, a through hole is provided on the second shell portion for the isolation pull tab to pass through. Compared with allowing the isolation pull tab to pass through the mating surfaces of the first shell portion and the second shell portion, the former has higher reliability. The reason is that when the isolation pull tab is allowed to pass through the mating surfaces of the first shell portion and the second shell portion, before the isolation pull tab is pulled out, there will be a gap between the first shell portion and the second shell portion, for example, and the gap can easily allow dust and water to enter, thereby affecting the reliability of the battery and the signal processing module.

[0042] See also Figure 2 , Figure 3 The signal processing module 13 includes a circuit board 131 and a chip 132 fixed on the circuit board 131, and the circuit board 131 is stacked on the battery 12. The second housing portion 11b includes a plurality of clamps 11f, and the circuit board 131 and the battery 12 are fixed to the second housing portion 11b through the plurality of clamps 11f.

[0043] The signal processing module may also include an antenna and a ZIF interface. The antenna is used to send data processed by the signal processing module to the client. The ZIF interface can be plugged into the terminal of the electronic circuit of the patch electrode to receive the electrical signal collected by the patch electrode.

[0044] In one embodiment, the first electrode 12a is located on the surface of the battery 12 facing the second housing portion 11b; the first connector 16 includes a spring portion 16a, the spring portion 16a is located between the battery 12 and the second housing portion 11b, the isolation tab 14 is located between the first electrode 12a and the spring portion 16a, and the spring portion 16a abuts against the bottom surface of the isolation tab 14; after the isolation tab 14 is pulled out, the spring portion 16a abuts against the bottom surface of the first electrode 12a. In this embodiment, the first electrode 12a is located on the bottom surface of the battery, the isolation tab 14 electrically isolates the first electrode 12a and the spring portion 16a, and the spring portion 16a has an elastic force, which causes the end of the spring portion 16a to generate an upward abutment force on the bottom surface of the isolation tab 14. Preferably, the end surface of the spring portion 16a has a protrusion, and the presence of the protrusion can further improve the connection reliability between the spring portion 16a and the first electrode 12a. The isolation tab 14 extends from between the battery 12 and the lower case portion 11 b to the outside of the case through the through hole 11 d .

[0045] Continue to see Figure 3 , Figure 4 The inner surface of the second housing portion 11b includes a groove 11g, the shape of the groove 11g is adapted to the shape of the elastic sheet portion 16a, and at least part of the elastic sheet portion 16a is in contact with the surface of the groove 11g. The groove 11g is provided to accommodate the elastic sheet portion 16a, so that the battery can be fixed flatly in the second housing portion 11b. The depth of the groove is between 0.1mm and 0.5mm, for example 0.2mm.

[0046] In order to fix the first connecting member 16 and the elastic sheet portion 16a in the second housing 11b, a first fixing member 15 is provided in the second housing portion 11b. The first fixing member 15 is provided adjacent to the groove 11g. At least part of the first connecting member 16 is accommodated in the first fixing member 15. The first fixing member 15 is configured to limit the position of the first connecting member 16. It can be understood that the existence of the first fixing member 15 can fix the first connecting member 16 so that it will not change position with the shaking of the housing. More importantly, the first fixing member 15 can make the elastic sheet portion 16a stably abut against the first electrode 12a, thereby improving the reliability of the signal acquisition device.

[0047] In one embodiment, a second fixing member 18 is disposed in the second housing portion 11b, and the second fixing member 18 includes a first contact area 181, a second contact area 182 and a third contact area 183, wherein the first contact area 181, the second contact area 182 and the third contact area 183 are disposed opposite to each other; wherein one end of the first connecting member 16 contacts the first contact area 181, one end of the second connecting member 17 contacts the second contact area 182, and the electrical connection terminal 131a contacts the third contact area 183. In this embodiment, the second fixing member limits the two connecting members of the battery and the connection terminal of the signal processing module to a smaller space range, facilitating the electrical connection between the two connecting members and the connection terminal, so that the battery can reliably supply power to the signal processing module.

[0048] In a more specific embodiment, the signal acquisition device further includes a first extruded connector 191 and a second extruded connector 192; the first extruded connector 191 is located between the first contact area 181 and the third contact area 183, and electrically connects the first connector 16 and the first contact point; the second extruded connector 192 is located between the second contact area 182 and the third contact area 183, and electrically connects the second connector 17 and the second contact point. In this embodiment, the first extruded connector and the second extruded connector are used to electrically connect the two connectors connected to the battery and the connection end of the signal processing module, eliminating the welding process, making the assembly process of the signal acquisition device safer and more reliable.
