Description

Circuit connection module for waterproof electrical connection detection body surface potential device

The present invention relates to a circuit connection module, in particular to a circuit connection module used for waterproof electrical connection to a body surface potential detection device.

The human body is very delicately designed, and because of this, if you want to explore the mysteries of the human body to solve the difficulties faced by human beings, such as diseases, or to promote scientific research to prevent future occurrences, it is the most basic work to properly understand the human body. Generally speaking, if no destructive exploration is carried out, the current state of the human body can be obtained by inputting energy such as ultrasound, X-ray, etc. to obtain changes in reflected or penetrating energy. Some local human body conditions, such as heart beating conditions, can be directly detected by detecting changes in body surface potential. Taking electrocardiography (ECG) as an example, it is a diagnosis and treatment technology that records the electrophysiological activities of the heart in units of time through the body surface, and captures and records trace potential changes through electrodes that contact the skin. The general way to obtain ECG data is to place more than 2 electrodes on the limbs, and measure them in pairs. The output signal of each pair of electrodes is a lead, and different leads are used to see the change of cardiac current from different angles to analyze the output signal. Many patients with chronic cardiovascular disease need to self-track the heart's functioning over a long period of time. To this end, many suppliers have developed electrocardiogram data detection devices that can be installed on the surface of the human body and are easy to carry.

A common portable electrocardiogram data detection device usually includes a flexible circuit board, a patch, an information collector and two conductive sheets. The patch and the information collector are sequentially stacked on the flexible circuit board, and the flexible circuit board is connected to the part to be detected of the human body through two conductive sheets to collect the physical information (voltage change) of the part to be detected of the human body. The vital information is transmitted to the information collector in the form of electrical signals from the conductive sheet through the metal connection part of the flexible circuit board, the flexible circuit board and the patch for subsequent processing. The conductive sheet is also provided with a metal connecting portion corresponding to the metal connecting portion. Although such a structure is simple, there is a problem: when the physical sign detection device is used in a humid environment, moisture is easily infiltrated between the metal connecting portion and the metal bonding portion, or between the metal connecting portion and the conductive sheet. These invading water vapors will cause data deviations in the body surface potential detected by the conductive sheet, which may cause noise in the sign information in light cases, or completely wrong sign information in severe cases. There is no specific solution to this problem. On the one hand, the industry usually uses the existing snap buttons as the metal connection part and the metal joint part to reduce the cost of mold opening; on the other hand, it is because the conductive sheet has a specific supply. such as CardinalHealth (producing Kendall ^TM 100 series foam electrode patches), 3M (producing ECG electrode patches), etc. These companies’ products have occupied a large market share, and they are required to modify existing specifications to strengthen waterproof treatment. , is practically impossible.

Structurally, the body surface potential detection device 5 is composed of four circuit connection modules 10 , a bearing structure 20 , a flexible waterproof and conductive assembly 30 and a circuit protection box 40 . In application, the circuit connection modules 10 that can be used by the body surface potential detection device 5 are not limited to the four shown in this embodiment, and may be an even number of two or more. The circuit connection module 10 can be detachably combined with the conductive buckle 51 of the conductive patch 50 , so as to obtain the potential signal detected at the conductive patch 50 . The structure and function of the circuit connection module 10 will be described in detail below.

It can be seen from the section of the circuit connection module 10 along the AA' section that the circuit connection module 10 includes a conductive base 100, a conductive fixing member 110, a waterproof conductive assembly 120, an insulating compression layer 130 and a Elastic insulating sleeve 140 . The conductive base 100 is made of metal material, preferably stamped from a piece of metal plate. Metal materials can be used but not limited to brass and stainless steel. The periphery 101 of the conductive base 100 is folded upward, the center and its adjacent parts protrude upward to form a protruding portion 102 , the highest point of the protruding portion 102 defines a coupling hole 103 , and an accommodating space 104 is formed inside. The accommodating space 104 can be used for accommodating a part of a conductive buckle 51 to be clamped. The conductive buckle 51 is made of metal material, which is combined with the existing conductive patches, such as the Kendall ^™ 100 series foam electrode patches from CardinalHealth Company, which can be purchased in the off-the-shelf market.

Therefore, except for the possibility of moisture intrusion below the interface between the elastic insulating sleeve 140 and the conductive buckle 51 , the remaining parts are completely electrically insulated from the surrounding environment and can prevent moisture intrusion. The existence of the above-mentioned exposed surface below the interface is because the conductive buckle base of each conductive patch may have different widths. The solution can be to increase the length of the lower edge of the elastic insulating sleeve 140 to cover all the exposed conductive buckle 51 as much as possible. part of the conductive patch. According to the present invention, the material of the elastic insulating cover 140 can be insulating rubber, insulating foam or silicone.

That is to say, in this embodiment, the insulating coating sleeve 111b is used to replace the combination of the insulating layer 111a and the insulating compression layer 130, which also has the functions of insulating and blocking moisture. The material of the insulating covering sleeve 111b can be insulating rubber, silicone or polyurethane.

The waterproof conductive assembly 120 is formed by arranging a silver paste conductive layer 120b between two flexible substrates 120a (represented by dotted lines), and the silver paste conductive layer 120b forms a circuit 121 . The aforementioned flexible substrate 120a may be made of polyethylene terephthalate (Polyethylene Terephthalate, PET) or mylar.

Finally, the inner wall thickness of the elastic insulating sleeve 140 is different, the upper edge is thicker, and the lower edge is thinner, so that the side of the conductive buckle 51 can be directly covered by the lower edge of the elastic insulating sleeve 140 .

Please refer to FIG. 6 , which is a schematic cross-sectional view of a third embodiment of the circuit connection module 10 for the waterproof electrical connection detection device for detecting body surface potential according to the present invention along the AA′ section in FIG. 2 .

As shown in FIG. 6 , the circuit connection module 10 in this embodiment also includes the conductive base 100 , the conductive fixing member 110 , the waterproof conductive assembly 120 and the elastic insulating cover 140 in the second embodiment. The difference between the present embodiment and the second embodiment is that the outside of the panel 111 of the conductive fixing member 110 is no longer covered with an insulating covering sleeve 111b, but is An insulating coating layer 111c is provided to extend and adhere to a part of the adjacent waterproof conductive assembly 120 . The difference between the two is that in the former, the insulating cover 111b can be covered with the panel 111 first, and then the conductive fixing member 110 is combined with the waterproof and conductive assembly 120, while in the latter, the conductive fixing member 110 is combined with the waterproof and conductive assembly 120 first, and then An insulating coating layer 111c is added to the surface of the device. Therefore, the material of the insulating coating layer 111c can also be insulating rubber, silicone or polyurethane. In addition, the circuit connection module 10 also has a conductive pad 150 with a vertical conductive function, which has a vertical conductive function and is placed between the conductive fixing member 110 and the waterproof conductive assembly 120 (in this embodiment, the conductive pad 150 is a ring In other embodiments, it can also be a short column structure), and the conductive spacer 150 is used to make the circuit between the conductive fixing member 110 and the waterproof and conductive assembly 120 (in this embodiment, silver The form of the adhesive conductive layer 120b exists) to form an electrical connection. The conductive gasket 150 is electrically connected to the circuit of the conductive fixing member 110 and the waterproof conductive assembly 120 first, and then the insulating coating layer 111c is adhered to a part of the adjacent waterproof conductive assembly 120, which is very convenient to manufacture.
