Abstract

The utility model discloses a circuit connection structure and a portable electrocardiograph. The circuit connection structure is simple and reasonable in structure, convenient to install and use and low in manufacturing cost. In this way, quick connection and disassembly of the host and the flexible patch can be achieved, and meanwhile after the host is connected with the positioning locking component, the elastic conductive needle arranged in the positioning locking component can be electrically connected with the conductive panel of the host stably. As the host does not need to be provided with a traditional elastic conductive structure and only needs to be provided with the conductive panel which can form a sealing structure with the shell of the host, and easily damaged parts of the host are reduced, the host can still keep good sealing performance and safety after being repeatedly used for multiple times.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a circuit connection structure that enables a stable electrical connection between the host and the flexible patch and prevents water from entering the host, as well as a portable electrocardiogram (ECG) monitor. Background Technology

[0002] According to statistics from the World Health Organization, cardiovascular disease currently has the highest mortality rate in the world. For high-risk groups of cardiovascular disease, long-term continuous electrocardiogram (ECG) monitoring can help detect potential dangers early and remind patients to seek medical treatment in a timely manner. Traditional ECG monitors used for ECG monitoring are bulky and inconvenient to carry, and often transmit ECG data in wired mode, which to some extent reduces the applicability of the ECG monitor and brings a poor user experience.

[0003] To address the issues of traditional ECG monitors being bulky and inconvenient to carry, portable ECG monitors have emerged. Portable ECG monitors (ECG patches) offer advantages such as simple structure, ease of use, small size, light weight, and portability without interfering with normal activities. A portable ECG monitor typically consists of a reusable main unit and a disposable patch. Since the electrode circuitry for collecting human bioelectrical signals is usually located on the patch, a contact-type conductive method is typically used between the electrode circuitry and the conductive terminals of the main unit to facilitate detachment from the patch.

[0004] In order to improve the contact conductivity after the host and the patch are connected, the conductive end of the host in the prior art usually adopts elastic conductive pin. After the elastic conductive pin on the host comes into contact with the electrode plate on the patch, it can maintain a relatively stable connection under the action of the elastic restoring force of the elastic conductive pin, thereby improving the conductivity.

[0005] However, since portable ECG monitors need to be worn by patients for extended periods of time, it is inevitable that the monitors will come into contact with water during showering or other similar situations. When the portable ECG monitors are in humid or water-filled environments, water will inevitably enter the elastic conductive pin of the main unit. Once this water enters the main unit, it will cause damage to the main unit.

[0006] Therefore, how to provide a circuit connection structure that can be used to connect the patch and the host, ensuring good electrical connection stability and good waterproof performance of the host after the host and the patch are connected, is a technical problem that urgently needs to be solved by those skilled in the art.

[0015] In its initial state, the flexible patch is connected to the first coating, and the conductive gel is located within the gel receiving portion;

[0016] In use, the first coating separates from the flexible patch, exposing the conductive gel so that the conductive gel can connect to the skin of the organism being tested.

[0017] Preferably, a plurality of the electrode circuits are disposed on the side of the flexible patch away from the organism to be tested; a second through hole is provided at the position corresponding to each of the electrodes on the flexible patch; the plurality of electrode circuits pass through the corresponding second through holes and are electrically connected to the plurality of electrodes one by one.

[0018] Preferably, the base plate of the positioning and locking component is provided with a slot structure, and one side wall of the slot structure is missing to form an insertion port.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 This is a circuit connection structure provided by an embodiment of the present utility model, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the structure may include:

[0040] A plurality of electrode circuits 1 and a plurality of electrodes 2 are connected one-to-one and are all disposed on a flexible patch 3. The plurality of electrode circuits 1 and the plurality of electrodes 2 are used to collect the bioelectricity generated by the heart of the organism under test.

[0041] A plurality of elastic conductive needles 4, one end of each of the plurality of elastic conductive needles 4 being electrically connected to a plurality of electrode circuits 1 respectively; the other end of each of the plurality of elastic conductive needles 4 extends through the base plate of the positioning locking member 5 into the interior of the positioning locking member 5; the positioning locking member 5 is used to connect to the main unit 9 of the portable electrocardiogram monitor.

[0042] After the host 9 is connected to the positioning and locking member 5, a plurality of elastic conductive needles 4 abut against a plurality of conductive ends 91 of the host 9 in a one-to-one correspondence, so that a plurality of electrode circuits 1 are electrically connected to a plurality of conductive ends 91 in a one-to-one correspondence, and the bioelectricity collected by a plurality of electrodes 2 is transmitted to the host 9; the conductive end 91 includes a sealed conductive panel.

[0043] The circuit connection structure provided in this application embodiment can use several electrodes 2 set on the flexible patch 3 to collect the bioelectricity generated by the heart of the living organism under test. After the host 9 is connected to the positioning and locking member 5 by lateral insertion, the conductive end 91 of the host 9 can establish an electrical connection with the elastic conductive needle 4, so that the bioelectricity is finally guided to the host 9 through the electrode circuit 1 and the elastic conductive needle 4. The host 9 can analyze the collected bioelectricity and finally obtain the electrocardiogram monitoring result.

[0044] Meanwhile, since an elastic conductive pin 4 is provided on one side of the flexible patch 3, after the main unit 9 is connected to the positioning locking component 5, the elastic conductive pin 4 can achieve a stable electrical connection with the conductive end 91 of the main unit 9 under its own elastic restoring force. Therefore, there is no need to provide a traditional elastic conductive pin 4 on the side of the main unit 9. Only a closed conductive panel needs to be provided to ensure that the main unit 9 maintains good sealing performance during several reuses.

[0045] The elastic conductive pin 4 provided in this embodiment is used as an intermediate component for electrically connecting the electrode circuit 1 and the conductive end 91 of the host 9. Since the electrode circuit 1 disposed in the flexible patch 3 usually needs to be a flexible circuit, and the elastic conductive pin 4 needs a stable support point for fixation, this embodiment can provide that the flexible patch 3 is provided with a first through hole 31, and a plurality of conductive materials 6 are deposited in the first through hole 31. The ends of the plurality of electrode circuits 1 away from the electrode 2 are connected to the plurality of conductive materials 6 one by one; the plurality of elastic conductive pins 4 are connected to the plurality of conductive materials 6 one by one.

[0046] In this embodiment, holes are made in the flexible patch, and conductive material is deposited in the holes to form a stable support point with excellent conductivity. Then, each elastic conductive pin is welded to the corresponding conductive material to form a stable support for the elastic conductive pin.

[0047] To further improve the conductivity after the electrode is connected to the organism to be tested, this application embodiment can provide a first coating 7 on the side of the flexible patch 3 near the organism to be tested, the first coating 7 being provided with a gel receiving portion 71, and the electrode 2 being provided with a conductive gel body 21 on the side near the organism to be tested.

[0048] In the initial state, the flexible patch 3 is connected to the first film 7, and the conductive gel 21 is located inside the gel receiving portion 71;

[0049] In use, the first coating 7 separates from the flexible patch 3, exposing the conductive aggregate 21 so that the conductive gel 21 can connect to the skin of the organism to be tested.

[0050] The first coating 7 is detachably connected to the flexible patch 3. When the product is not in use (initial state), the first coating 7 is connected to the flexible patch 3, protecting the flexible patch 3 and related electrodes 2, conductive gel 21, etc. When needed, the first coating 7 is separated from the flexible patch 3, and the conductive gel 21 is aligned with the corresponding position on the organism to be tested to collect the bioelectricity generated by the heart.

[0051] Understandably, to better protect the flexible patch and related components, a second coating 8 can be provided on the side of the flexible patch 3 away from the organism being tested. Similarly, when the product is not in use, the second coating 8 is connected to the flexible patch 3 to protect it. When needed, the second coating 8 can be separated from the flexible patch 3.

[0052] When specifically setting up electrode circuit 1 and electrode 2, both electrode circuit 1 and electrode 2 can be placed on the side of flexible patch 3 closest to the organism to be tested (see...). Figure 1 Alternatively, electrode circuit 1 and electrode 2 can be positioned on the side of flexible patch 3 away from the organism being tested. This is because the positioning locking member 4 is positioned on the side of flexible patch 3 away from the organism being tested. Figure 1 As shown, when the electrode circuit 1 and the electrode 2 are placed on the side of the flexible patch 3 close to the organism to be tested, the electrode circuit 1 can be directly connected to the electrode after being connected to the elastic conductive needle 4 through the first through hole 31.

[0053] When both electrode circuit 1 and electrode 2 are located on the side of flexible patch 3 away from the organism to be tested, the end of electrode circuit 1 closest to the electrode needs to be led out from flexible patch 3 to connect electrode circuit 1 to the electrode. Therefore, embodiments of this application can provide several electrode circuits 1 located on the side of flexible patch away from the organism to be tested; the flexible patch 3 is provided with a second through hole (not shown in the figure) at the corresponding position of each electrode 2; several electrode circuits 1 pass through the corresponding second through holes and are electrically connected to several electrodes 2 one by one.

[0054] The positioning locking member 5 provided in this embodiment serves as a connector between the main unit 9 and the flexible patch 3. In practice, this embodiment can provide a slot structure 51 on the base plate of the positioning locking member 5. One side wall of the slot structure 51 is missing to form an insertion port. This insertion port allows the main unit 9 of the portable ECG monitor to be inserted into the slot structure 51 from the side and fixed by the slot structure 51. The positioning locking member 5 adopts a side-mounted insertion port. When the main unit 9 needs to be connected to the flexible patch 3, the user simply holds the main unit 9 and inserts it into the slot within the positioning locking member 5 through the insertion port to achieve a secure connection.

[0055] To further improve the structural stability after the host 9 is connected to the positioning and locking member 5, this embodiment of the application provides an elastic locking tongue 52 on the base plate of the positioning and locking member 5 near the insertion port. The host 9 has a groove 92 on its housing. After the host 9 is inserted into the slot structure 51, the elastic locking tongue 52 enters the groove 92 to lock the host 9 to the positioning and locking member 5. The provided elastic locking tongue 52 can move towards the flexible patch 3 under the action of a vertical external force in the direction of the flexible patch 3, thus releasing the insertion port for the host 9 to be inserted. When the host 9 is fully inserted, the external force on the elastic locking tongue 52 disappears, and it springs back into the groove 92 to lock the host 9.

[0056] The elastic locking tongue 52 can be made by setting a connection at one end and forming notches on three sides on the base plate. When it is necessary to separate the host 9 from the flexible patch 3, the user can push the host 9 into the slot structure 51. After the host 9 is in place, the protrusion of the elastic locking tongue 52 can enter the groove 92 on the outer shell of the host 9 to lock the host 9.

[0057] It is understood that the elastic conductive pin 4 provided in this embodiment protrudes from the upper surface of the base plate of the positioning locking member 5. In order not to affect the normal insertion of the host 9, this embodiment can provide that the portion of the elastic conductive pin 4 located outside the base plate of the positioning locking member 5 has a spherical structure. The portion of the elastic conductive pin 4 located above the base plate adopts a spherical outer contour structure, which can ensure that the elastic conductive pin 4 and the initial contact part of the host 9 form an arc transition, thereby facilitating the insertion of the host 9.

[0058] To improve the conductivity of the conductive protrusion structure, embodiments of this application may further provide a coating on the surface of the spherical structure to enhance conductivity. Furthermore, the coating material includes any one of copper, silver, and gold. By providing a coating with stronger guiding properties on the surface of the spherical structure, and after achieving good electrical connection stability, conductivity can be further improved, which is beneficial for more complete transmission of bioelectrical signals to the host 9, thereby improving the accuracy of electrocardiogram (ECG) indicator detection.

[0059] It is understood that the conductive end 91 of the host 9 provided in this application embodiment exists in the form of a sealed conductive panel. In practical applications, the conductive panel can be embedded and fixedly set on the shell of the host 9, so as to ensure that it can both achieve electrical connection with the elastic conductive pin 4 and form a sealed structure to ensure that there are no gaps in the shell of the host 9 that allow water to enter.

[0060] To further improve the connection stability between the elastic conductive pin 4 and the main circuit board inside the host, this embodiment of the application may also provide that the conductive panel is fixedly disposed on the housing of the host, and the conductive panel is connected to the main circuit board inside the host through a conductive elastic element.

[0061] In a practical implementation, a through hole can be provided on the housing of the host 9, and a conductive elastic element can be provided inside the host 9. One end of the conductive elastic element is connected to the conductive panel. After the conductive elastic element is compressed, it is connected to the main circuit board inside the host, which can improve the stability of the connection between the conductive panel and the main circuit board.

[0062] In summary, the circuit connection structure provided in this application is simple and reasonable, easy to install and use, and inexpensive to manufacture. It enables quick connection and disconnection between the main unit and the flexible patch. Furthermore, after the main unit is connected to the positioning and locking component, the elastic conductive pin within the positioning and locking component can achieve a stable electrical connection with the conductive panel of the main unit. Since the main unit does not require a traditional elastic conductive structure, only a conductive panel that forms a sealed structure with the main unit's casing is needed. This reduction in vulnerable parts ensures that the main unit maintains good sealing and safety even after repeated use.

[0063] This application embodiment can also provide a portable electrocardiogram (ECG) monitor, including a flexible patch body, a main unit, and the circuit connection structure described above.

[0064] During manufacturing, the flexible patch body and the circuit connection structure of this portable ECG monitor can be made into a single component. When needed, the main unit is first connected to the flexible patch body through the circuit connection structure and the positioning locking component. Then, the flexible patch is attached to the detection position determined by the subject and the flexible patch is adhered to the skin of the subject. The main unit can then be turned on to perform ECG detection.

[0065] To further improve the adhesion between the flexible patch and the skin of the organism being tested, embodiments of this application may provide an adhesive layer on the side of the flexible patch facing the organism being tested, and a release layer on the outside of the adhesive layer. This adhesive layer is protected by the release layer, preventing the adhesive effectiveness from failing or weakening during transportation after leaving the factory. When the flexible patch needs to be applied, the release layer and adhesive layer are separated, and the flexible patch can then be applied to the skin surface of the organism being tested, ensuring a firm attachment and reducing the possibility of relative displacement between the flexible patch and the human skin during movement.

[0066] Furthermore, the release layer includes either a paper-based single-sided silicone release layer or a PET-based single-sided silicone release layer. Both paper-based and PET-based single-sided silicone release layers can adhere to the prepreg, yet are easy to separate. When ambient temperature and humidity change, the length and width of the release paper remain constant, preventing wrinkling of the release paper and thus avoiding wrinkling of the prepreg in the adhesive layer. It also possesses sufficient density to prevent moisture from entering the prepreg through it.

[0067] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
