The device has the functions of collecting, storing, intelligently analyzing and warning ECG information. It also has the characteristics of accurate monitoring, touch screen control, simple and convenient. Traditional ECG monitors have a large number of wire harnesses when connecting piezoelectric chips. When patients turn over and move, the wire harnesses are often pressed under the body, damaging the skin and affecting the service life of the wire harnesses.

[0025] Example: See Figure 1 , Figure 2 and Figure 3 A liquid ECG integrated monitor comprises a liquid monitoring module, an ECG oxygen monitoring module, a real-time display processing module and a remote alarm module. The liquid monitoring module and the ECG oxygen monitoring module transmit signals to the real-time display module in a real-time wireless unidirectional manner, and the real-time display processing module transmits signals to the remote alarm module wirelessly. The liquid monitoring module comprises a photoelectric sensor 3 for monitoring the liquid in an infusion tube 8, a microcontroller 4 connected to the photoelectric sensor 3 signal, a signal transmitter 5 connected to the microcontroller 4 for control and a liquid tube blocking mechanism 1, and a battery 2 for connecting the various components. The ECG oxygen monitoring module comprises a signal acquisition and transmission box, an electrode patch, an oxygen saturation monitoring clip, a respiratory monitor, a blood pressure monitor and a battery 2.
[0026] The liquid monitoring module and the ECG oxygen monitoring module transmit data to the real-time display module in real-time wireless one-way. The real-time display processing module displays the patient's ECG, blood pressure, respiratory rate and oxygen saturation data, and does not need to connect a data cable, which is convenient for the patient to get out of bed and walk. The remote alarm module can be placed on the medical staff or the nurse station. When the patient has abnormal data, the real-time display processing module wirelessly transmits signals to the remote alarm module, and the medical staff can receive and process them in time; when the liquid monitoring module finds that the liquid is used up, the liquid pipe blocking mechanism 1 can clamp the infusion pipe 8 in time to block the circulation and prevent air from entering the patient's blood vessels.
[0027] The real-time display processing module includes a wireless transmission circuit, a signal processing circuit, a signal storage circuit and a display screen. The wireless transmission circuit and the signal processing circuit are bidirectionally connected, and the signal processing circuit and the display screen are unidirectionally transmitted. The wireless transmission circuit includes a receiving circuit and a transmitting circuit. The receiving circuit signal is connected to the receiving liquid monitoring module and the electrocardiograph oxygen monitoring module, and the transmitting circuit signal is connected to the remote alarm module.
[0028] The remote alarm module includes a housing 6 and a battery 2, a signal receiver, a signal processor, a buzzer and several LED lamp beads arranged therein, and the signal receiver is connected to the transmitting circuit signal of the display processing module. The signal processor is electrically connected to the battery 2, data connected to the signal receiver, and connected to control the buzzer and LED lamp beads. Each LED lamp bead corresponds to a signal of a monitoring module, such as a liquid monitoring alarm, an abnormal heart rate alarm, an oxygen saturation alarm, etc. When medical staff see which light is on or flashing, they can know what situation has occurred roughly, which is convenient for preparing tools for processing. When each light flashes, a buzzer sounds, which is convenient for medical staff to detect.
[0029] The signal acquisition and transmission box is connected to the oxygen saturation monitoring clip through the oxygen saturation wire and connected to the electrode patch through the ECG wire. Each electrode patch is attached to the patient, and the signal is sent to the signal acquisition and transmission box through the ECG wire. The oxygen saturation monitoring clip is clamped on the patient's finger, and the signal acquisition and transmission box is connected through the oxygen saturation wire. The signal acquisition and transmission box is provided with a battery 2 and a control circuit, a signal conversion circuit and a signal sending circuit. The signal sending circuit is connected to the receiving circuit signal of the real-time display processing module. The battery 2 supplies power to each circuit, the signal conversion circuit connects the ECG wire and the oxygen saturation wire, converts the received electrical signal and sends it to the control circuit, and the control circuit sends instructions to the signal sending circuit, sends the heart rate signal and the oxygen saturation signal to the receiving circuit of the real-time display processing module, and then displays it.
[0030] The signal acquisition and transmission box is a small box with a built-in battery 2, which can be carried around and communicates wirelessly with the display. The patient is no longer restricted when he needs to move his body, giving the patient a certain amount of free movement space.
[0031] like Figure 4As shown, the liquid monitoring module includes a shell 6, a battery 2, a photoelectric sensor 3, a microcontroller 4, a signal transmitter 5 and a liquid pipe blocking mechanism 1 are all placed in the shell 6, and a through groove 7 is opened on the shell 6 for the infusion tube 8 to pass through and clamp. The photoelectric sensor 3 includes a light transmitter and a light receiver symmetrically arranged on both sides of the through groove 7. The shell 6 is also provided with a clamping block 9 for clamping and fixing the infusion tube 8. The clamping block 9 is located at both ends of the through groove 7 on the shell 6, and its inner diameter is slightly smaller than the outer diameter of the infusion tube 8. In this way, the infusion tube 8 is clamped so that the entire liquid monitoring module will not fall. During the infusion process, the photoelectric sensor 3 monitors the presence of liquid in the infusion tube 8 in real time. When the liquid is exhausted, its light perception changes, and the signal is transmitted to the microcontroller 4. The microcontroller 4 sends a command to the liquid pipe blocking mechanism 1 to clamp the infusion tube 8 so that it no longer flows. The microcontroller 4 sends an instruction to the signal transmitter 5, and the signal transmitter 5 sends the information of liquid depletion to the real-time display processing module. The signal processing circuit of the real-time display processing module processes the signal and sends it to the display screen for display. If the display continues for a preset time without processing, a signal is sent to the remote alarm module to alarm; the signal storage circuit can store various received signals for easy reference and export of data in the future.
[0032] like Figure 5 Figure 6 As shown, the liquid tube blocking mechanism 1 is an electromagnetic clamping component connected and controlled by a microcontroller 4, which includes two clips 11 connected by a hinge 14, wherein an electromagnet 12 is provided at the non-connected end of one of the clips 11, and an iron sheet 13 matching the electromagnet 12 is provided at the corresponding position at the end of the other clip 11, and the middle position of the two clips 11 matches the shape of the infusion tube 8 in the compressed state. The liquid tube blocking mechanism 1 starts to work when it receives the working command of the microcontroller 4, the battery 2 energizes the electromagnet 12 to generate magnetism, and adsorbs the iron sheet 13 of the other clip 11, and the other clip 11 rotates under the action of the hinge 14, and the two clips 11 clamp the infusion tube 8 together under the action of the lever, so that the infusion tube 8 is deformed and "blocked", and no flow is generated, preventing air from entering the patient's blood vessels and ensuring the safety of the patient.
