Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sealing connection structure that enables a waterproof and sealed connection between the host and a flexible patch, 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 two parts: a reusable main unit and disposable patches.

[0004] Since portable ECG monitors need to be worn by patients for extended periods of time, they inevitably come into contact with water during showering or other similar situations. To ensure the safety of the main unit, higher requirements are placed on the waterproof performance of the portable ECG monitor's main unit.

[0005] Traditional portable ECG monitors typically use a semi-enclosed structure for the patch used to secure the main unit. This design facilitates both the connection and separation of the main unit and the patch. However, this semi-enclosed connection significantly reduces the waterproof performance of the portable ECG monitor. When the monitor is in a damp or wet environment, water inevitably enters at the electrical connection point between the main unit and the patch. If this water enters the main unit through its conductive terminals, it can cause damage.

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

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0034] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , a sealing connection structure provided by an embodiment of the present application is shown as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , which can include:

[0035] Positioning and locking member 1, the positioning and locking member 1 is used to be connected with a flexible patch 2, the flexible patch 2 is used to be attached to the skin surface of a to-be-measured living body; the flexible patch 2 is provided with a plurality of electrode circuits 3 and a plurality of electrodes 4 corresponding to the plurality of electrode circuits 3 on the side close to the to-be-measured living body, the plurality of electrodes 4 are used to collect bioelectricity generated by the heart of the to-be-measured living body; a bottom plate of the positioning and locking member 1 is provided with an annular cover 11 with an open top, an inner part of the annular cover 11 forms a cavity structure, and the cavity structure is used to accommodate a host 6 of a portable electrocardiogram detector;

[0036] Conductive connecting plate 5, a first end of the conductive connecting plate 5 is connected with a plurality of electrode circuits 3, and a second end of the conductive connecting plate 5 extends to the inside of the cavity structure through the bottom plate; the second end of the conductive connecting plate 5 is used to establish electrical connection with a conductive end of the host 6, so as to transmit the bioelectricity collected by the electrode 4 to the host 6;

[0037] The annular cover body 11 is gradually inclined inwardly from the bottom plate to the direction away from the bottom plate, and the upper edge of the annular cover body 11 is provided with a ring-shaped elastic sealing ring 12, which is used to fix the main machine 6 and the annular cover body 11 and seal the connection after the main machine 6 is inserted into the cavity structure.

[0038] The sealing connection structure provided by the embodiment of the application can collect biological electricity generated by the heart of a life body through the electrodes 4 arranged on the flexible patch 2. After the main machine 6 is connected to the positioning and locking member 1 in a vertical insertion manner, the conductive end of the main machine 6 can be electrically connected to the conductive connecting plate 5, so that the biological electricity is finally guided to the main machine 6 through the electrode circuit 3 and the conductive connecting plate 5. The main machine 6 can analyze the collected biological electricity and finally obtain an electrocardiogram monitoring result.

[0039] The conductive connecting plate 5 can exist as an independent component and be connected to the electrode circuit 3 through welding or the like. The conductive connecting plate 5 can also be formed at the distal end of the electrode circuit 3 in an extended manner.

[0040] Meanwhile, the annular cover body 11 adopts an inwardly inclined structure, that is, a space sufficient to accommodate the main machine 6 can be formed in the annular cover body 11, and the opening of the annular cover body 11 can be formed in a closed structure. The elastic sealing ring 12 arranged in cooperation can ensure that the gap between the annular cover body 11 and the main machine 6 is sealed after the main machine 6 is inserted, so as to prevent water and water vapor from entering the inside of the annular cover body 11, achieve a good waterproof sealing effect, and improve the safety of the main machine 6.

[0041] The elastic sealing ring 12 provided by the embodiment of the application can be made of rubber material and has a certain elastic deformation capacity, that is, the main machine 6 can be smoothly and vertically inserted into the annular cover body 11, and the connection can be sealed under the action of the elastic deformation force.

[0042] In order to further improve the sealing performance of the elastic sealing ring 12 and prevent the elastic sealing ring 12 from affecting the insertion of the main machine 6, the elastic sealing ring 12 can include at least one sealing lip 121 protruding toward the inside of the annular cover body 11. The sealing lip 121 can be used as the contact part of the elastic sealing ring 12 and the main machine 6, has better deformation capacity, and also has good sealing performance. In actual use, a plurality of sealing lips 121 can be arranged in an upper and lower interval, so as to ensure that a single sealing lip 121 has excellent deformation capacity and form a plurality of sealing structures to ensure good sealing effect.

[0043] To further improve the sealing effect, the free end of each of the sealing lips 121 can be arranged in an inclined state towards the bottom plate. The free end of the sealing lip 121 is inclined towards the bottom plate, which is conducive to reducing the interference with the host 6 when the host 6 is inserted, ensuring that the host 6 can be smoothly inserted into the annular cover body 11, and at the same time, the sealing effect is not affected.

[0044] The positioning and locking member 1 provided by the embodiment of the present application adopts a full-enclosing structure to achieve connection with the host 6, and good sealing effect can be obtained. However, when the host 6 needs to be separated from the positioning and locking member 1, the full-enclosing structure can cause the problem that it is difficult to separate the host 6 from the positioning and locking member 1. To effectively solve this problem, the embodiment of the present application can provide that the positioning and locking member 1 is provided with a stress-weak structure 13, and the positioning and locking member 1 can be broken at the stress-weak structure 13, so that the host 6 can be separated from the positioning and locking member 1. Through the provision of the stress-weak structure 13, when the host 6 needs to be separated from the positioning and locking member 1, the positioning and locking member 1 can be broken at the stress-weak structure 13, and after the positioning and locking member 1 is broken, the host 6 can be separated from the positioning and locking member 1, and the host 6 can be taken out of the annular cover body 11.

[0045] It can be understood that the stress-weak structure 13 can be arranged at any position that does not affect the sealing effect. For example, in one implementation, the embodiment of the present application can provide that the stress-weak structure 13 includes a sink 131 extending from one side to the opposite side arranged on the bottom plate and a notch 132 opposite to the sink 131 arranged on the annular cover body 11. The stress-weak structure 13 can be formed by the sink 131 arranged on the bottom plate and the notch 132 opposite to the sink 131 arranged on the annular cover body 11. During the breaking process, the bottom plate and the annular cover body 11 can be broken under the action of external force, ensuring that the breaking effect is sufficient, so that the host 6 can be completely separated from the positioning and locking member 1.

[0046] The conductive connecting plate 5 provided by the embodiment of the present application needs to pass through the bottom plate to be connected with the electrode circuit 3. To reduce the processing difficulty, the second end of the conductive connecting plate 5 can extend to the inside of the cavity structure through the sink 131. When the sink 131 is processed, a through hole through which the conductive connecting plate 5 passes can be directly processed, which does not affect the arrangement of the stress-weak structure 13, and at the same time, two different functional ports can be formed by one-time processing, greatly reducing the processing difficulty and processing time.

[0047] The conductive connecting plate 5 provided by the embodiment of the present application can be used as an intermediate connecting piece between the electrode circuit 3 and the conductive end of the host 6. The first end of the conductive connecting plate 5 is connected to the electrode circuit 3 in a fixed manner, and the second end of the conductive connecting plate 5 is electrically connected to the conductive end of the host 6 in a contact manner. Therefore, it is necessary to ensure that the second end of the conductive connecting plate 5 has a stable connection structure with the conductive end of the host 6. To this end, the second end of the conductive connecting plate 5 can be bent to form an inclined structure facing away from the bottom plate. The second end of the conductive connecting plate 5 can form a structure similar to a spring arm. During the connection of the host 6 and the annular cover body 11, the conductive connecting plate 5 can be squeezed, and the elastic potential energy can be stored after being squeezed. When the connection of the host 6 and the annular cover body 11 is completed, the conductive connecting plate 5 can be in close contact with the conductive end of the host 6 under the action of the elastic restoring force, achieving good conductivity and ensuring that the circuit is smooth even if the connection of the host 6 and the annular cover body 11 is loose.

[0048] In summary, the sealing connection structure provided by the present application has simple and reasonable structure, convenient installation and use, and low manufacturing cost. The host and the flexible patch can be quickly connected and detached, and after the host is connected with the positioning and locking member, the connection part can be sealed by the elastic sealing ring of the annular cover body, achieving good waterproof sealing effect, effectively solving the problem of poor waterproof performance of the connection part of the host and the flexible patch of the portable electrocardiogram detector, and expanding the application range and application scenarios of the portable electrocardiogram detector. At the same time, the annular cover body can be broken along the provided stress weak structure, so as to realize the convenient and quick separation of the host and the flexible patch.

[0049] The embodiment of the present application can also be a portable electrocardiogram detector, which includes a flexible patch body, a host, and the sealing connection structure.

[0050] The portable electrocardiogram detector can be manufactured as an integral component with the flexible patch body and the sealing connection structure during processing. When in use, the host is connected to the flexible patch body through the sealing connection structure, and then the flexible patch is attached to the determined detection position of the measured living body and is pasted to the skin of the measured living body. The host can be started to perform electrocardiogram detection.

[0051] In order to further improve the combination ability of the flexible patch and the skin of the to-be-tested living body, the flexible patch is provided with an adhesive layer on the side facing the to-be-tested living body, and an external release layer is arranged on the adhesive layer. The adhesive layer can be protected by the release layer, and the adhesion effect of the adhesive layer can be prevented from being lost or weakened during transportation after leaving the factory. When it is necessary to attach the flexible patch, the release layer is separated from the adhesive layer, and then the flexible patch is attached to the skin surface of the to-be-tested living body, so as to ensure the firmness of the attachment of the flexible patch and reduce the possibility of relative displacement between the flexible patch and the human skin during movement,

[0052] Further, the release layer comprises one of a paper-based single-sided silicon release layer or a PET-based single-sided silicon release layer. The paper-based single-sided silicon release layer or the PET-based single-sided silicon release layer can stick to the prepreg, but can also easily separate the two; when the ambient temperature and humidity change, the length and width of the release paper can remain unchanged, and the release paper will not wrinkle to cause the prepreg to wrinkle, and the release paper has sufficient density to prevent moisture from entering the prepreg.

[0053] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
