Description

Technical Field

[0001] The utility model relates to the technical field of blood pressure meter equipment, in particular to a blood pressure meter. Background Art

[0002] Upper arm electronic blood pressure monitors are widely used because they are easy to operate and patients can measure their blood pressure at home at any time. The general structure of the upper arm electronic blood pressure monitor includes a blood pressure monitor body and an armband. When in use, the user ties the armband on the upper arm (the plug at the tracheal end of the armband is inserted into the tracheal seat jack connected to the exhaust end of the air pump), and then presses the start button of the blood pressure monitor body (the two contacts under the start button are closed, so that the positive power supply of the battery enters the main control system of the blood pressure monitor body, and the main control system can control the blood pressure monitor body to automatically work for a period of time to measure blood pressure). The air pump in the blood pressure monitor body adds high-pressure gas to the armband for a period of time. During the systolic pressure measurement process, the high-pressure airflow generated when the heart contracts fills the cuff airbag to the highest pressure, which is the systolic pressure, also known as high pressure. During the diastolic pressure measurement process, the cuff airbag pressure gradually decreases when the heart relaxes, which is the diastolic pressure, also known as low pressure. The blood pressure monitor body calculates the human blood pressure value through the measurement results of systolic pressure and diastolic pressure, and displays the result on the screen of the blood pressure monitor body. Since the upper arm electronic blood pressure monitor can measure blood pressure quickly and accurately, it has been widely used in clinical diagnosis and at home.

[0003] Although the existing upper arm electronic blood pressure meter meets the needs to a certain extent, it is limited by the structure and still has some specific problems. Specifically, for patients with high blood pressure and unstable blood pressure, the medical guidelines require general patients to perform blood pressure tests every day to obtain the blood pressure change data of the patient within a day. The existing upper arm electronic blood pressure meter does not have a reminder function. In this way, when the patient forgets to measure on time for various reasons or does not measure blood pressure within a day, there are certain safety hazards (such as failure to monitor the corresponding high blood pressure data, failure to adjust the medication according to the corresponding high pressure data, etc., causing cerebrovascular accidents in patients, etc.). In addition, the trachea and the main tracheal seat of the current upper arm electronic blood pressure meter are connected by intubation. After a long time of use, there is a probability that the seal between the outer side of the tracheal plug and the inner side of the main tracheal seat will deteriorate due to wear. In this way, the high-pressure gas output from the air pump inside the main unit to the armband will leak, which will cause the final detection result of the blood pressure meter body to be biased. In summary, it is particularly necessary to provide a blood pressure meter that can remind patients to measure blood pressure on time and can minimize air leakage between the tracheal plug and the tracheal seat. Utility Model Content

[0004] In order to overcome the drawbacks of the existing upper arm electronic blood pressure monitor due to structural limitations as described in the background, the utility model provides an upper arm electronic blood pressure monitor body, which, under the joint action of relevant mechanisms and circuits in application, can make a sound to remind the user to measure blood pressure during a specific time period every day, and stop making the sound only after the patient has been measured, thereby achieving a good reminder effect and minimizing air leakage between the tracheal plug and the tracheal seat, thereby providing effective technical support for accurate blood pressure measurement.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A blood pressure monitor comprises an upper arm electronic blood pressure monitor body, characterized in that it also comprises a timing circuit and a prompt circuit; a left magnet sheet is installed at the outer end of a tracheal seat of the blood pressure monitor body, a right magnet sheet is installed at the tracheal plug of the blood pressure monitor body, and a sealing sheet is installed at the side of the left magnet sheet; the timing circuit and the prompt circuit are installed in the blood pressure monitor body, the tracheal plug is inserted into the tracheal seat, the two poles of the battery in the blood pressure monitor body are electrically connected to the power input ends of the timing circuit and the prompt circuit, and the signal output end of the timing circuit is electrically connected to the signal input end of the prompt circuit; the power output end of the start button of the blood pressure monitor body is electrically connected to the control end of the prompt circuit.

[0007] Furthermore, the right side end of the left magnet and the left side end of the right magnet have opposite polarities.

[0008] Furthermore, the timing circuit includes an electrically connected time relay module and a resistor, the positive power input terminal of the time relay module and the positive control power input terminal are connected, the negative power input terminal of the time relay and the negative control power input terminal are connected, and the output terminal of the time relay module is connected to one end of the resistor.

[0009] Furthermore, the prompt circuit includes an electrically connected thyristor, a buzzer and a relay, the normally closed contact terminal of the relay is connected to the anode of the thyristor, the cathode of the thyristor is connected to the positive power input terminal of the buzzer, and the negative power input terminal of the buzzer is connected to the negative power input terminal of the relay.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model is based on the upper arm electronic blood pressure meter body. In application, the timing circuit and the prompt circuit can sound a reminder to the user to measure blood pressure at a specific time period every day, and the sound will stop after the patient is measured. In this way, a good reminder effect is achieved, and the safety hazard caused by the patient not measuring blood pressure on time is prevented; after the tracheal plug is inserted into the tracheal seat, the left and right magnets are attracted together and there is a sealing rubber pad, so even if the outer side of the tracheal plug and the inner side of the tracheal seat are worn and the sealing performance deteriorates, it will not cause air leakage between the tracheal plug and the tracheal seat, which provides effective technical support for accurate blood pressure measurement. Based on the above, the utility model has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] Figure 1 It is a schematic diagram of the overall three-dimensional structure and the local enlarged structure of the utility model.

[0013] Figure 2 This is a circuit diagram of the utility model. DETAILED DESCRIPTION

[0014] Figure 1 , 2 As shown in the figure, a blood pressure meter includes an upper arm electronic blood pressure meter body 1, and also has a timing circuit 2 and a prompt circuit 3; a hollow annular left magnet sheet 102 is glued to the outer end of the tracheal seat 101 of the blood pressure meter body, an annular hollow right magnet sheet 104 is glued to the left side of the tracheal plug 103 of the blood pressure meter body, and an annular hollow sealing sheet 105 is glued to the right side of the left magnet sheet; the timing circuit 2 and the prompt circuit 3 are installed on the circuit board inside the blood pressure meter body 1, and the tracheal plug 103 is inserted into the tracheal seat 101.

[0015] Figure 1 , 2 As shown in , the right side end of the left magnet 102 and the left side end of the right magnet 103 have opposite polarities. The timing circuit includes a time relay module A1 and a resistor R1 connected via circuit board wiring, the positive power input terminal 1 pin of the time relay module A1 is connected to the positive control power input terminal 3 pin, the negative power input terminal 2 pin of the time relay A1 is connected to the negative control power input terminal 4 pin, and the output terminal 9 pin of the time relay module A1 is connected to one end of the resistor R1. The prompt circuit includes a thyristor VS, a buzzer B1 and a relay J1 connected via circuit board wiring, the normally closed contact terminal of the relay J1 is connected to the anode of the thyristor VS, the cathode of the thyristor VS is connected to the positive power input terminal of the buzzer B1, and the negative power input terminal of the buzzer B1 is connected to the negative power input terminal of the relay J1. The two poles of the battery G1 in the blood pressure meter body and the 1st and 2nd feet of the time relay module A1 at the power input end of the timing circuit, the control power input end and the negative power input end of the power input end relay J1 of the prompt circuit are respectively connected via wires, and the other end of the resistor R1 at the signal output end of the timing circuit and the control pole of the thyristor VS at the signal input end of the prompt circuit are connected via wires; the power output end of the start button S1 of the blood pressure meter body and the positive power input end of the signal end relay J1 of the prompt circuit are connected via wires.

[0016] Figure 1 , 2As shown, when the blood pressure monitor body 1 is used, the user ties the armband 106 on the upper arm (the tracheal plug of the armband is inserted into the tracheal seat jack connected to the exhaust end of the air pump), and then presses the start button S1 of the blood pressure monitor body. The two contacts under the start button are closed, so that the positive power supply of the battery G1 enters the high-level signal input end of the main control system A2 of the blood pressure monitor body. The main control system A2 can control the blood pressure monitor body 1 to automatically work for a period of time to measure the blood pressure. The air pump 1 in the blood pressure monitor body adds high-pressure gas to the armband 106 for a period of time. During the systolic pressure measurement process, the high-pressure airflow generated when the heart contracts fills the cuff airbag to the highest pressure, which is the systolic pressure, also known as high pressure. During the diastolic pressure measurement process, the cuff airbag pressure gradually decreases when the heart relaxes, which is the diastolic pressure, also known as low pressure. The blood pressure monitor body 1 calculates the human blood pressure value through the measurement results of the systolic pressure and diastolic pressure, and displays the result on the screen of the blood pressure monitor body, so that the user can understand his current blood pressure data in real time. After the time relay module A1 is powered, its 9th foot will output a certain time power at a certain interval (for example, 2 seconds power is output at 8 am and 8 pm, and the actual time is adjustable), and the resistor R1 will reduce the voltage and limit the current to trigger the controllable VS to turn on (the power output by the battery G1 enters the thyristor VS anode through the relay J1 control power input terminal and the normally closed contact terminal), and then the buzzer B1 will sound to remind the user that it is time to measure blood pressure. When the user measures blood pressure and presses the start button S1 of the blood pressure meter body 1, the relay J1 will be powered to attract its control power input terminal and the normally closed contact terminal to open the circuit, then the thyristor VS anode will be cut off due to the lack of high-level input (at this moment, the 9th foot of the time relay module A1 no longer outputs a high level), and then the buzzer B1 will no longer be powered to sound. Through the above, the present invention can make a sound to remind the user to measure blood pressure at a specific time period every day, and stop making a sound only after the patient has measured. In this way, a good reminder effect is achieved, and the safety hazard caused by the patient not measuring blood pressure on time is prevented; after the tracheal plug is inserted into the tracheal seat, the left and right magnets are attracted together and there is a sealing rubber pad, so even if the outer side of the tracheal plug and the inner side of the tracheal seat are worn and the sealing performance deteriorates, it will not cause air leakage between the tracheal plug and the tracheal seat, which provides effective technical support for accurate blood pressure measurement. Figure 2In the figure, the resistance value of resistor R1 is 10K; the time relay module A1 is a time controller module of model YYC-2S, which has two power input terminals 1 and 2, two trigger signal input terminals 3 and 4, a setting button 5, an emergency stop button 6, a time plus button 7, a time minus button 8, and a normally open power output terminal 9. After the operator presses the setting button, he operates the time plus button and the time minus button respectively, and the normally open power output terminal can be set to output positive power in the required time period. After the time is set and the two trigger signal input terminals are input with a trigger power signal, the time relay module product will count the set time; the relay J1 model is DC5V; the thyristor VS model is MCR100-1; the buzzer B1 is a model FM5V active continuous sound buzzer alarm product.
