Patent CN205094431U discloses a household portable electrocardiograph, wherein a display screen is installed on the outer wall of a shell, and a detection button is installed on the left side of the display screen; the right end of the shell is provided with an electrode detector, and the inside of the shell is provided with a processor and an electrocardio detection module; the signal output end of the electrode detector is connected with the electrocardio detection module, the signal output end of the electrocardio detection module is connected with the processor, and the signal output end of the processor is provided with a wireless transmitter; the detection terminal is arranged outside the shell, and a wireless receiver which is used for information transmission with the wireless transmitter is arranged on the detection terminal. The household portable electrocardiograph is small in size and convenient to carry, can be used as a portable medical instrument, and is convenient to measure and check pace-making electrocardiograms in time. The processor can perform multiple functions of data acquisition, waveform display, alarm, storage, transmission, analysis and the like, and can complete multiple inspections in the shortest time, thereby saving time and obtaining inspection results in real time.

Patent CNCN2601078 discloses a household electrocardiographic detector, which aims to provide a household electrocardiographic detector with small volume, portability and easy operation, which can detect and analyze the basic electrocardiographic parameters. The key point of the technical scheme is that the device comprises an analog amplification circuit, a data processing chip, a liquid crystal display, an alarm buzzer and a power supply part in an insulating shell. The analog amplification circuit amplifies electrocardiosignals collected by external electrocardioleads, inputs the amplified signals into a data processing chip for A/D conversion, sampling, storage and calculation, and the output of the data processing chip is divided into two paths, one path is connected to an alarm buzzer and the other path is connected to a liquid crystal display.

The utility model is an electrocardio-detecting instrument suitable for household.

Patent CN202776279U discloses a multi-functional health detector, and it is equipped with a plurality of detection interfaces, and detection interface is connected with the detection module who carries out different detection projects on the mainboard for the detection of a plurality of physiological indexes can once only be accomplished to the detector. The core purpose of the patent is to process a plurality of detection items simultaneously, and simultaneously display a large amount of measurement data on a display screen (see figure 4 thereof). Since the detector is intended to emphasize expandability, its portability is limited to itself; if the detection instruments such as electrocardio, pulse, heart rate, body temperature, blood pressure, blood sugar and blood fat are taken into consideration, the volume of the device is increased greatly, and the portability is lost. As can be seen from the description and fig. 1, the device is actually equivalent to a physiological index collecting terminal, and is used for collecting and displaying the collected data on the monitor when various existing detecting instruments are connected. The patent does not relate to various reasonable settings of an external detection instrument and a detector when used in a combined manner, for example, how to reasonably set the MCU and the A/D conversion module on the detector and the external detection instrument to achieve optimal detection and minimum volume is not considered, the problems of data connection and processing are not related to reasonably reduce redundant electronic components, and the problem of power supply of the external detection instrument is not considered.

In the prior art, there are also a variety of split-type detection systems, most of which are that the detection device and the host are integrated into a whole, and the host can independently perform various functions of detection and display, and the host is connected to the detection device in a wireless or wired connection manner for data collection. The host and the detection equipment are independent, a large amount of repeated equipment of power supply, data, operation and display is caused, equipment cost is brought, and meanwhile, equipment portability is reduced objectively. Under the system, if a host is matched with more than ten different detection devices, an embarrassing scene that the airplane cannot be carried or transported due to too many lithium batteries is likely to occur.

The single lead electrocardiograph detectors used in the prior art still have at least one or more of the following technical problems:

1. redundant functions represent a higher manufacturing cost.

2. The corresponding detection equipment is easy to become electronic garbage when not used, and resource waste is easy to cause.

3. The corresponding detection equipment has a large volume, and is not easy to carry about so as to be suitable for various random occasions.

Therefore, there is a need in the market for a single lead ecg monitor that includes a detection module (especially, a separately storable or separable detection module) that can be combined with a portable multifunctional health detection system for the purpose of performing corresponding detection.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor has studied a lot of documents and patents when making the present invention, but the space is not limited to the details and contents listed in the above, however, the present invention is by no means free of the features of the prior art, but the present invention has been provided with all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a portable single-lead electrocardiogram detector, aiming at solving at least one or more technical problems in the prior art.

In order to achieve the above object, the present invention provides a portable single lead electrocardiograph detector, which at least comprises: the single-lead electrocardiogram detection module can be connected to an external module and/or equipment to form a complete single-lead electrocardiogram detector in a combined mode; and the interface is arranged on the single-lead electrocardiogram detection module so as to at least realize mechanical connection and/or signal transmission between the single-lead electrocardiogram detection module and the external module and/or equipment.

Preferably, the single-conductor cardiac detection module at least comprises a limiting part, and the limiting part can cover at least a part of the shell of the external module and/or the equipment which are connected in a matching way through the interface so as to limit the relative movement between the external module and the equipment and/or protect the external module and/or the equipment. The limiting part can be used for bearing the operating pressure between the blood oxygen detection module and the external module and/or the device when the blood oxygen detection module is connected to the external module and/or the device through the interface in a matching mode, and the electronic interface is prevented from being damaged.

Preferably, the limiting part arranged on the single lead electrocardiogram detection module can be in a shape which is suitable for the external module and/or the equipment shell when the single lead electrocardiogram detection module is connected with the external module and/or the equipment in a matching way. In addition to connection stability and bearing force, the mechanical fit using the external shape is also beneficial to reducing the storage volume, facilitating carrying of multiple split detection modules and external modules and/or devices.

Preferably, the single-lead ECG detection module further comprises at least one electrode plate and at least one circuit board integrated with electronic components, wherein the electrode plate can be tightly attached to the part to be detected so as to acquire the value of potential change in the specific region.

Preferably, the interface is integrated and/or connected to the circuit board to realize a docking relationship between the single lead electrocardiograph detection module and the external module and/or the device, wherein the single lead electrocardiograph detection module realizes power and/or signal transmission only when connected to the external module and/or the device through the interface, and the power comes from the external module and/or the device. In other words, the single lead heart detection module does not need to be provided with a battery and does not need to consider charging, but obtains power from the connected external module and/or device when the detection work is started. The volume of the single-lead electrocardiogram detection module is reduced to a certain extent, and energy waste when the single-lead electrocardiogram detection module is not used is avoided.

Preferably, the interface arranged on the single-conductor cardiac detection module and the limiting part capable of adapting to the shape of the external module and/or the device shell are positioned on the same side. The design that the interface and the limiting part are positioned on the same side of the shell is more favorable for avoiding the false pulling of the interface and the limiting part during detection operation.

Preferably, the single lead electrocardiographic detection module sends an identity authentication request to the external module and/or device only when the single lead electrocardiographic detection module is connected to the external module and/or device through the interface in a matching manner, so that the external module and/or device can configure the split detection module based on the corresponding identity, for example, to establish an operation mode of the single lead electrocardiographic detection module or detect a state thereof.

Preferably, the detection data of the single-lead ECG detection module is only sent to the external module and/or the display part on the equipment through the interface so as to be at least displayed, output and stored. An external device with a battery or power source may be more advantageous for processing or forwarding data. From a system perspective, such an arrangement saves unnecessary operating and display components overall.

Preferably, the detection direction of the single lead electrocardiograph detection module and the connection direction arranged on the single lead electrocardiograph detection module are not parallel to each other.

Preferably, the limiting part capable of adapting to the shape of the external module and/or the device shell is positioned at a different side from the operation area of the external module and/or the device connected to the single lead electrocardiogram detection module through the interface. The possibility of misoperation of related personnel when corresponding detection tasks are executed can be avoided through the arrangement mode of the non-identical side.

Preferably, when the single lead electrocardiograph detection module is operated after being connected with the external module and/or the device, the interaction force between the single lead electrocardiograph detection module and the external module and/or the device can be reduced and/or counteracted through the limiting part, so that the movement of the single lead electrocardiograph detection module is limited in at least one of three degrees of freedom of pitching, translation and rotation. This arrangement is advantageous for performing the testing task after the single lead ECG testing module is docked with other external devices, because when the two are docked, the pressure from the operating components (which can be disposed on the external module and/or equipment outside the split testing module) must be commonly borne by the combination of the two, and the mechanical shape matching mode of the two is convenient for bearing the pressure. On the other hand, when the single lead electrocardiograph detection module is used for carrying out corresponding detection tasks, the required stability of the single lead electrocardiograph detection module also needs to depend on the connected external module and/or equipment, and the stability in at least one of three degrees of freedom of pitching, translation and rotation is favorable for the stability of connection, so that the detection precision is favorable.

The utility model has the beneficial technical effects that:

1. the single-lead electrocardiogram detection module obtains power through the external module and/or the equipment connected with the single-lead electrocardiogram detection module, energy consumption can be reduced, and the single-lead electrocardiogram detection module is economical and environment-friendly.

2. The single-lead electrocardio detection module is not electrified, and the electronic and/or mechanical structure is simpler, so the cost is low, and the cost can be greatly saved.

3. The single-lead electrocardiogram detector is small and exquisite and light in appearance, can be flexibly disassembled for split charging and storage, and can be carried about, so that the single-lead electrocardiogram detector is suitable for various random occasions.

4. The structure of the single-lead electrocardiogram detector is beneficial to the close cooperation between the single-lead electrocardiogram detector and the host, and the comfort level of related personnel in the using process is improved.
