Portable detector of blood clarifying device

Abstract

The invention relates to a portable detector of a blood clarifying device. The detector has two big parts which are respectively a main machine part and a detecting part. The main machine part is divided into eight modules, namely a power supply module, a data selecting module, an A / D (analog / digital) converting module, a keystroke module, a communication module, a liquid crystal display module, a reset module and a singlechip processing module. The detecting part comprises five sensors. Signals of the five-path sensors are input to the data selecting module; the output of the data selecting module is connected with the input end of the A / D converting module; the output end of the A / D converting module is connected with the singlechip processing module; and the signal is connected with the liquid crystal display module to display after being processed by the singlechip. The keystroke module, the reset module and the communication module are connected with the singlechip processing module. The power supply module supplies power for the main machine part. The detector disclosed by the invention has the advantages of multifunction, high precision, low cost and is portable and the like.

Description

technical field [0001] The invention relates to a portable detector, in particular to a portable blood purification device detector. Background technique [0002] In recent years, the rapid development of my country's economy has accelerated people's work rhythm and increased work pressure, while the time for physical exercise has been continuously reduced. On the other hand, environmental pollution degrades the functions of people's respiratory system and digestive system, and the number of patients suffering from acute and chronic renal failure (uremia) is increasing and showing a trend towards younger age. The current treatment mainly adopts hemodialysis, which is to lead the patient's blood out of the body, and replace the metabolic function of the kidneys with a hemofiltration device (referred to as a blood purification device), so as to remove the pathogenic substances, purify the blood, and relieve the disease. The pain of the patient, the purpose of treating the dis...

Problems solved by technology

However, a very serious problem is: with the increase of the service life and frequency of the blood purification device, the accuracy of the main measurement parameters of the instrument, such as conductivity, pH value, temperature, pressure, flow rate, etc., will change to a certain extent. If the changed parameters cannot be found in time and adjusted to the range allowed by the calibration specification, in mild cases, the quality of hemodialysis of the patient will be reduced, and in severe cases, the life safety of the patient may even be threatened

[0003] However, because the hemodialysis machine is not a strong inspection measuring instrument, there was no calibration standard before, so the inspection cannot be carried out.

Some users only rely on the self-test function of the equipment itself to perform instrument self-inspection. Without calibration equipment and testing personnel, it is impossible to determine whether the measurement parameters of the equipment are accurate and reliable.

[0004] According to the calibration standard to be implemented by the country, the calibration of the blood purification device mainly uses conductivity detectors, temperature detectors, pressure detectors, pH detectors and flow detectors to measure the conductivity of the dialysate, the temperature of the dialysate, and the dialysate. Important performance indicators such as hydraulic pressure, dialysate pH value and dialysate flow rate, not only the use of many instruments, but also labor-intensive and time-consuming, low work efficiency, and it is almost difficult to achieve on-site detection

Some large-scale medical institutions import special testing instruments for blood purification devices with multiple functions from developed countries such as the United States and Germany. However, due to their high prices and small quantities, regional medical institutions and technical supervision departments are often unable to purchase such instruments. instrument
