Fish real-time ECG miniature collecting method, device and system

Abstract

The invention discloses a fish real-time ECG miniature collecting method, device and system. The device comprises a waterproof shell. The waterproof shell comprises a waterproof shell body and a waterproof cover in sealing connection with the waterproof shell body. A miniature ECG signal processing device, and a storage device and a battery which are connected with the miniature ECG signal processing device are fixedly placed in the waterproof shell body. The miniature ECG signal processing device is connected with an electrode through a wire. An electrode lead-out opening is formed in the bottom end of the waterproof shell. The electrode pierces in a pericardial cavity of a fish body to collect original ECG signals and transmits the ECG signals to the miniature ECG signal processing device through the wire to be processed. A through hole for placing an infrared signal transmitting device is formed in the side face of the waterproof shell. The transmitting end of the infrared signal transmitting device is in sealing connection with the through hole. The infrared signal transmitting device is connected with the battery and the miniature ECG signal processing device and transmits theprocessed ECG signals to an infrared signal receiving device matched with the infrared signal transmitting device so that fish real-time ECG signal collection can be completed.

Description

technical field [0001] The disclosure belongs to the technical field of electrocardiographic signal collection of aquatic organisms, and relates to a method, device and system for real-time electrocardiographic miniaturization collection of fish. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Among the currently studied aquatic organisms, most of the research objects are fish. In the fields of physiology and physiological ecology, research on fish ECG is becoming more and more extensive. By collecting fish ECG, we can understand heart rate, Heart rhythm, and possibly changes in the waveform. In the process of collecting the ECG signal of the fish, it must be ensured that the fish body does not struggle and swing randomly, so as to avoid the electrode misalignment or even slipping due to the swimming of the fish.

AI Technical Summary

Problems solved by technology

[0005] First, to collect fish ECG at present, it is necessary to connect the acquisition electrodes to the ECG acquisition and analysis instrument to ensure that the collected ECG signals can be recorded and output normally, and can be preserved manually, so that there is no guarantee for the space. In the normal state of the fish, due to the limited wires and the inability of the circuit to work in the water, the surface of the fish body is relatively slippery and easy to struggle and swing, so the acquisition instrument cannot be placed on the fish body or in the water, and it is difficult to do it like a human portable ECG measuring instrument. Acquisition of ECG signals cannot avoid space constraints

[0006] Second, the anesthesia before the experiment had a certain impact on the physiological and pathological characteristics of the fish, and interfered with the heart rate measurement. The ECG collected under anesthesia could hardly reflect its normal physiological characteristics; It is easy to cause the experimental fish to die due to lack of water, and placing it horizontally on the experimental table cannot keep the fish in a normal state in the water, resulting in inaccurate ECG signal measurement

[0007] Third, the existing fish ECG collection methods currently have a short collection time. Since the normal life activities of the fish are short after leaving the water, it is impossible to carry out long-term real-time online collection, and cannot obtain continuous ECG signals. Read and analyze changes in the exact time of ECG
