DETAILED DESCRIPTION

[0026] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0027] Example

[0028] According to the utility model, an electrocardiogram recorder with replaceable electrodes is provided. Figure 1-4 As shown, it includes a host 1, an electrode 2 and a data transmitter 3. The host 1 is rotatably connected to the electrode 2. The host 1 is provided with a protrusion, and the electrode 2 is provided with a groove. The host 1 is connected to the electrode 2 through the cooperation of the protrusion and the groove. The data transmitter 3 is connected to the host 1 and is used to build a data transmission channel between the device and the host computer. In normal use, the host 1 is first connected to the electrode 2, and the electrode 2 is glued to the designated position of the human body. After collecting enough signals, it is removed, and after separating the host 1 from the electrode 2, the host 1 is connected to the data transmitter 3, and the data transmitter 3 is connected to the host computer to export data.

[0029] The host 1 is composed of a host upper cover 11, a host lower cover 12 and a host circuit board assembly 13, wherein the host circuit board assembly 13 includes a core circuit part, an LED indicator light and a spring probe connector. The main bodies of the host upper cover 11 and the host lower cover 12 are made of hard materials. There is an opening in the center of the host upper cover 11 and an elastic sealing material is injection-molded as a host upper cover rubber ring 14. The host upper cover rubber ring 14 also has a button function. A circle of elastic sealing material is injection-molded on the outer edge of the host lower cover 12 as a host lower cover rubber ring 15. There are multiple axial positioning and plane positioning protrusions, and a light-transmitting thin-walled position with a surrounding vertical wall, which is used to transmit the indicator light arranged on the circuit board. The host circuit board assembly 13 is placed on the host lower cover 12, and is plane-positioned by multiple cylindrical positioning pins and a groove-shaped protrusion, and axially positioned by two C-shaped protrusions. The groove-shaped positioning protrusion has a notch that is plugged into the slot at the corresponding position of the host upper cover 11, and is assisted in positioning by a plurality of cylindrical positioning pins to realize the mutual positioning of the host lower cover 12 and the host upper cover 11, and the plurality of cylindrical positioning pins are conducive to the transmission of torque. After the positioning of the host circuit board assembly 13 is completed, the host upper cover 11 is crimped onto the host lower cover 12 to realize the fixation of the host circuit board assembly 13. The upper surface of the outer edge of the host lower cover 12 has a draft angle. When the host upper cover 11 is crimped, it expands along this inclined surface due to elasticity until it is elastically restored at the step where it is crimped to the host lower cover 12, thereby realizing the clamping. After the crimping is completed, the rubber ring 14 of the host upper cover is aligned with the button on the host circuit board assembly 13. The button can be triggered by pressing the rubber ring 14 of the host upper cover. At the same time, the contact avoidance hole of the host lower cover 12 is aligned with the spring probe connector on the host circuit board assembly 13. Each spring probe in the spring probe connector extends out of the avoidance hole to connect with the electrode 2 or the data transmitter 3 to form a communication circuit. In addition, the LED indicator light on the host circuit board assembly 13 is also aligned with the light-transmitting thin wall position. In addition, the outer surface of the light-transmitting thin wall position can be designed with a pattern to match the light indication effect.

[0030] The electrode 2 is composed of an electrode upper cover 21, an electrode lower cover 22, an electrode circuit board assembly 23, an adhesive assembly 24 and a battery 25. The electrode circuit board assembly 23 includes a core circuit part, a battery compartment, a flexible circuit connector and a spring probe connector contact. The adhesive assembly 24 includes an ECG signal acquisition component, a flexible circuit and a backing adhesive.

[0031] A circle of elastic sealing material is injected near the outer edge of the upper surface of the electrode upper cover 21 as the electrode upper cover rubber ring 26. Several protrusions are arranged around the electrode upper cover rubber ring 26 to prevent relative slippage during the rotation installation process of the electrode 2 and the host 1. In addition, several annular protrusions are arranged on the contact surface with the host 1 to enhance waterproofing. The positioning of the electrode circuit board assembly 23 is mainly achieved by the outer circular support of the electrode lower cover 22 and two slots of unequal widths. At the same time, the wider slot is provided with a notch to be plugged into the slot at the corresponding position of the electrode upper cover 21. After the battery 25 is installed in the battery compartment of the electrode circuit board assembly 23 to realize power supply, the flexible circuit part of the adhesive assembly 24 is inserted into the notch of the host lower cover 12 and firmly bonded to the host lower cover 12. The flexible circuit part is connected to the flexible circuit connector arranged on the lower surface of the electrode circuit board assembly 23. Similar to the host, the electrode lower cover 22 is also molded with an electrode lower cover rubber ring 27, and the electrode circuit board assembly 23 is crimped and installed in the same way. After the crimping and installation is completed, the spring probe connector contacts of the exposed part of the electrode circuit board assembly 23 and the rotating clamping part of the electrode upper cover 21 have a high relative position accuracy. The electrode 2 is a disposable device, and it is difficult to disassemble the shell after the crimping and installation is completed, so the battery 25 cannot be replaced. The expected circuit life can be adjusted by controlling the number of batteries 25 placed in the battery compartment.

[0032] The data transmitter 3 is composed of a transmitter upper cover 31, a transmitter lower cover 32, a transmitter circuit board assembly 33, a transmitter bottom rubber ring 34, a transmitter counterweight 35, a transmitter silicone 36 and a data line 37. The transmitter circuit board assembly 33 includes a core circuit part, a data line connector and a spring probe connector.

[0033] The positioning method of the upper and lower covers and the circuit board assembly of the data transmitter 3 is consistent with that of the electrode 2. The upper and lower covers are bonded together. Since the data transmitter 3 does not need to be placed on the human body, no waterproof rubber ring is designed. The transmitter lower cover 22 is designed with a larger inner compartment for placing and bonding the transmitter counterweight 35, and a groove is opened in the transmitter lower cover 32 for bonding the transmitter silicone. The transmitter counterweight 35 and the transmitter silicone 36 are both used to place it relatively stably on the desktop. The upper end side of the transmitter lower cover 32 is provided with a notch for connecting the data cable 37, which can be connected to the host computer by wire through the data cable 37. The surface of the transmitter circuit board assembly 33 is arranged with spring probe connector contacts consistent with the electrode 2. The electrode upper cover 21 or the transmitter upper cover 31 is designed with multiple notches, and is L-shaped in the longitudinal section. The design of the host lower cover 12 has the same number and arrangement of protrusions. The widths of the protrusions and grooves are not consistent, achieving a fool-proof effect.

[0034] More importantly, the side surfaces of the corresponding positions of the mainframe upper cover 11, the electrode upper cover 21 and the transmitter upper cover 31 after installation are provided with indication marks. When the mainframe 1 is connected to the electrode 2 or the data transmitter 3, the protrusion of the mainframe lower cover 12 is first aligned with the L-shaped groove-shaped notch, and then rotated circumferentially until the indication mark of the mainframe upper cover 11 is aligned with the indication mark of the electrode upper cover 21 or the transmitter upper cover 31, which indicates that the installation is in place.

[0035] The outer edges of the host cover 11, the electrode cover 21 and the transmitter cover 31 can be provided with a plurality of anti-skid grooves for anti-skid application during the installation process. Indicator marks can be provided on the upper surface of the host cover 11 for more convenient observation of the alignment. The connection between the data transmitter 3 and the host cover 11 can be achieved by other simpler connection methods such as direct snap-in, crimping, magnetic attraction, gravity placement, etc. for more convenient operation. During the installation and twisting process, each spring probe of the spring probe connector of the host 1 is pressed on the electrode circuit board assembly 23, and a certain contact force is provided by the internal spring. When installed in place, each spring probe is aligned with the spring probe connector contact to form a signal and power supply path. At this time, the LED indicator lights up and the electrode 2 starts working.

[0036] The utility model solves the problem of difficulty in ensuring sealing performance while installing quickly by combining a sealing rubber structure with a small cross-section protrusion and a rotating buckle design, ensures the function of reliable waterproof and quick installation under a small-size layout, achieves a systematic waterproof effect for the wearer to wash and shower, and has the performance of easy disassembly and replacement. At the same time, since the seal is processed on the electrode for one-time use, the risk of seal failure caused by repeated use and wear is avoided. The utility model solves the problem of high sealing requirements for flexible circuit structures and difficulty in simplifying production processes by combining a three-layer buckle installation with multiple step axial positioning and multiple bayonet axial positioning with a back-adhesive flexible circuit structure, achieving the effects of sealing, quick installation, simple assembly with a small number of parts, reliable connection, and not easy to disassemble and fall off. By adopting a universal contact and foolproof positioning structure, the installation steps are simplified, the circuit connection operation is eliminated, the problem of time-consuming and labor-intensive multi-step operation for quick installation is solved, and the effect of quick replacement or quick reading of data is achieved.
