Abstract
The utility model discloses a double-sensor blood pressure measuring intelligent protection circuit, comprising a pressure sensor, a CPU (Central Processing Unit) and a blood pressure drive module, wherein the double-sensor blood pressure measuring intelligent protection circuit is provided with two sets of independent pressure sensors and the CPU; the pressure sensor is used for detecting the blood pressure measuring pressure; the CPU is used for comparing the blood pressure measuring pressure signal detected by the pressure sensor with the preset pressure protection conditions; control signals are output so as to control the work of the blood pressure drive module; and two CPUs output signals and control the work of the blood pressure drive module through an OR gate. The protection circuit can prevent dangers occurring in any condition; a recorder can work normally when one sensor of the protection circuit is fault; and the protection circuit protects the sick not being damaged furthest.
Description
Technical field
This utility model relates to a kind of dual sensor blood pressure measurement intelligent protection circuit.
Background technology
Common blood pressure measurement device generally all is provided with a cover holding circuit; But when this cover holding circuit broke down, the improper meeting of blood pressure measurement damaged human body limb, even under little pressure; If the long-time limb compression of patient also can cause and not accommodate injury.
Summary of the invention
This utility model purpose is to the defective of prior art a kind of dual sensor blood pressure measurement intelligent protection circuit to be provided.
This utility model adopts following technical scheme for realizing above-mentioned purpose:
A kind of dual sensor blood pressure measurement intelligent protection circuit; Comprise pressure transducer, CPU and blood pressure driver module; It is characterized in that: said dual sensor blood pressure measurement intelligent protection circuit has separate pressure transducer and the CPU of two covers; Wherein said pressure transducer is used to detect blood pressure measurement pressure, and CPU is used for the detected blood pressure measurement pressure signal of pressure transducer is compared with preset pressure protect condition, the work of output control signal controlling blood pressure driver module; Two CPU output signal through or the work of gate control blood pressure driver module.
It is further characterized in that: said blood pressure driver module comprises air pump control circuit and vent valve control circuit, is used to control air pump work inflation and vent valve work venting.
Its further characteristic also is: described preset pressure protect condition is:
When pressure surpasses 315mmHg, vent valve is exitted immediately;
Or when pressure be 300 mmHg～310 mmHg values, the time, vent valve was exitted immediately above 10 seconds;
Or work as pressure greater than 15 mmHg, the time, vent valve was exitted immediately when surpassing 180 seconds.
This utility model can prevent the harm that occurs under the different condition, even monitor still can operate as normal under the holding circuit single failure.Protect patient not come to harm to greatest extent.
Description of drawings
Fig. 1 is this utility model circuit block diagram.
The specific embodiment
A kind of dual sensor blood pressure measurement intelligent protection circuit as shown in Figure 1; Comprise pressure transducer, CPU and blood pressure driver module; It is characterized in that: said dual sensor blood pressure measurement intelligent protection circuit has separate pressure transducer and the CPU of two covers; Wherein said pressure transducer is used to detect blood pressure measurement pressure, and CPU is used for the detected blood pressure measurement pressure signal of pressure transducer is compared with preset pressure protect condition, the work of output control signal controlling blood pressure driver module; Two CPU output signal through or the work of gate control blood pressure driver module.
It is further characterized in that: said blood pressure driver module comprises air pump control circuit and vent valve control circuit, is used to control air pump work inflation and vent valve work venting.
Its further characteristic also is: described preset pressure protect condition is:
When pressure surpasses 315mmHg, vent valve is exitted immediately;
Or when pressure be 300 mmHg～310 mmHg values, the time, vent valve was exitted immediately above 10 seconds;
Or work as pressure greater than 15 mmHg, the time, vent valve was exitted immediately when surpassing 180 seconds.
When any sleeve pressure sensor and CPU detected blood pressure measurement pressure and reach preset pressure protect condition, pressure protect was carried out in the work of blood pressure driver module.
