Description

Technical Field

[0001] The present invention relates to the technical field of barium enema, and particularly relates to an intelligent control type barium enema device. Background Technique

[0002] With the continuous development of digital imaging technology, the clinical application of barium contrast examination technology has become more extensive. An important reason is that there is no need to insert instruments into the body (such as endoscopes). By only taking orally or enema with barium sulfate, it can relieve the pain of patients, especially suitable for children, the elderly or those intolerant to invasive operations. The digital dynamic images generated by the examination are suitable for clearly showing the gastrointestinal function of patients, significantly improving the detection rate of functional lesions, and then providing more reliable and accurate imaging information for the diagnosis and treatment of digestive tract diseases. Barium contrast examination technology is mainly used for gastrointestinal radiography. The composition of barium meal is barium sulfate, and at the same time, the dynamic images of the contrast examination can be very conveniently stored permanently through the PACS storage system. During X-ray examination, due to the different densities and thicknesses of various organs and tissues in the human body, natural black and white level contrasts are shown. However, in some parts of the human body, especially the gastrointestinal tract, because there are multiple organs overlapping in the body and the densities of tissues are generally similar, it affects the diagnosis of diseases. Introducing a contrast agent harmless to the human body (such as medical barium sulfate) can significantly improve the display contrast, show the lesion site, and achieve an ideal examination effect. Barium contrast technology does not belong to an invasive operation, has no irritating taste and toxicity, is easy for patients to accept, and can improve their cooperation. The X-ray contrast examinations most commonly used are gastrointestinal barium meal contrast and barium enema contrast. Although the development of gastroscopy, CT, and MR imaging technologies is very rapid, due to the advantages of barium contrast examination technology such as safety, non-invasiveness, no side effects, low examination cost, and the ability to take dynamic films, it plays an irreplaceable role in imaging diagnosis. When diagnosing a patient before gastrointestinal or esophageal examination, barium agent is ingested. The barium agent will not dissolve in the gastric acid containing hydrochloric acid in the gastrointestinal tract, so it can successfully adhere to the gastrointestinal wall like the ingested food. The parts of the gastrointestinal wall with surface losses such as ulcers cannot adhere. Swallowing barium or barium enema examination can only see the outline of the digestive tract, and the digestive tract filled with barium agent often masks small lesions. Therefore, a foaming agent is often taken orally or air is injected into the intestine to make there be both high-density barium agent and low-density air shadow in the gastrointestinal tract, forming an air-barium double-contrast image, which is easy to obtain positive results. According to the needs of clinical diagnosis and treatment, gastrointestinal barium meal contrast can be divided into upper gastrointestinal barium meal, whole gastrointestinal barium meal, colon barium enema, and small intestine barium enema examinations. When taking an X-ray of the gastrointestinal tract, since X-rays cannot penetrate solid barium sulfate, the barium meal will leave a shadow on the photo, and the part without a shadow is the lesion site. Gastrointestinal barium meal examination is the most commonly used method for examining gastrointestinal lesions. It is used to examine lesions of the esophagus, stomach, small intestine, colon, and rectum, such as ulcers, tumors, inflammation, and congenital variations; lesions of the peritoneum, such as peritoneal tuberculosis and intestinal adhesions; abdominal masses, to understand the relationship between the mass and the gastrointestinal tract, so as to make a differential diagnosis. If the contrast agent is left standing for too long, it is easy to cause precipitation, which directly affects the effect of barium contrast. Sometimes, if the diagnosis of a certain part takes too long, the precipitation of the contrast agent will also occur. Ensuring that the barium agent is in a good suspension state under any circumstances helps the diagnosis of barium contrast.When the barium dose is insufficient and needs to be replenished, the precipitation phenomenon is more obvious due to the long placement time. At the same time, when the ingested and instilled barium agents are stored in an environment of about 10 °C, the cold barium agent entering the body will cause discomfort to the patient. Therefore, a control device is needed to keep the barium agent in a good suspension state and constant temperature state all the time. Barium agent imaging examination has certain advantages in patients with gastrointestinal diseases, which can improve the cooperation of patients, and has high diagnostic sensitivity, specificity, and accuracy, and low cost. In particular, the long-term storage of patient imaging data greatly facilitates the imaging comparison during the follow-up visit of patients, which is conducive to clinical application and promotion.

[0022] It should be noted that the present invention is an intelligent control type barium enema device, and the single-chip microcomputer control module 3 is an ATmega2560 single-chip microcomputer. When a doctor confirms the contrast diagnosis required by a patient, barium agent and water are added to the barium agent storage barrel 4 in accordance with a specified ratio. At this time, the eccentric oscillator 10 is in the barium agent solution, and the ATmega2560 single-chip microcomputer directly starts the eccentric oscillator 10 to enter the stirring and oscillating state by detecting the state of the barium agent solution through the infrared emission and reception sensor group 6 until the barium agent solution is uniform; then it enters the working preparation state; when the suspended barium agent precipitates, the concentration of the barium agent solution will change. Through the infrared emission and reception sensor group 6, the control circuit starts to operate, and the motor of the eccentric oscillator 10 rotates forward and backward and then enters micro-vibration, so as to keep the barium agent solution always in the suspended state required for clinical diagnosis. The ATmega2560 single-chip microcomputer controls the vibration intensity of the eccentric oscillator 10 by changing the PWM pulse width of the PWM circuit carried by the ATmega2560 chip itself to adjust the intensity of the oscillation. The operation signal of the micro-motion device for fully automatic uniform stirring of the barium agent depends on the control of the gastrointestinal machine. After receiving the signal of the external gastrointestinal machine being turned on, a clinician pours barium sulfate and water required according to the patient's condition into the barium agent storage barrel 4. After the ATmega2560 single-chip microcomputer operates to achieve a uniform state of the barium agent and heats to a constant temperature state, the circuit enters the preparation state for barium agent perfusion, and the data collected by the temperature sensor 11 is passed through l 2It is transmitted to the ATmega2560 single-chip microcomputer through the C interface. Then, the data read is processed within the ATmega2560 single-chip microcomputer, and the data of each sensor is fused to control the temperature to maintain a constant temperature of about 36 degrees Celsius. The current temperature is displayed in real time through the display component 5 externally attached to the barium agent cup. The barium agent capacity sensor is actually a liquid level sensor 9 responsible for measuring the capacity in the barium agent cup. When the barium agent drops to the set threshold, a signal is sent to the display component 5 outside the barium agent cup through the single-chip microcomputer to display the information that the barium agent capacity is too low, and a beeping alarm signal is emitted through the speaker. The thin-film pressure sensor is used to fix the position of the customized double-chamber anal tube for enema in the intestine. When the anal tube enters the appropriate position, the micro air pump 17 works to inflate the airbag installed at the head of the anal tube. The pressure sensor detects the pressure of the airbag on the intestinal wall during the inflation process to achieve the effect of fixing the position tightly against the intestinal wall. The infrared emission and reception diode group detects the suspension state in the barium agent cup and controls the operation of the eccentric motor. The design idea of the software program of the ATmega2560 single-chip microcomputer can be mainly divided into three steps: system initialization, hardware detection, and data processing, judgment, and startup operation. System initialization is the start of the program and an indispensable part, which will ensure whether each sensor can work normally; hardware detection can ensure that each part works normally and can greatly reduce the program debugging time; data processing and judgment algorithms are the core of the entire program. Different data from different sensors need to be comprehensively judged to reduce errors. The overall process of the ATmega2560 single-chip microcomputer program is shown in the figure. The normal working state of the circuit adopts a combination of real-time display on the display component 5 and voice broadcast reminder. When the doctor confirms the contrast diagnosis required by the patient, barium agent and water are added to the barium agent storage bucket 4 according to the specified ratio and directly placed on the eccentric oscillator 10. The sensor directly starts the eccentric oscillator 10 to enter the stirring and oscillating state by detecting the state of the solution until the barium agent is uniform; then it enters the working preparation state; when the suspended barium agent precipitates, the concentration of the solution will change. Through the emission and reception of the light-emitting diode 1, the control circuit starts to operate. After the motor of the eccentric oscillator 10 rotates forward and backward, it enters micro-vibration to keep the barium agent always in the suspended state required for clinical diagnosis. The thin-film pressure at the top of the barium agent input tube of the device detects that the pressure signal is very small, basically between 100Mv - 500Mv. The DF9-40 sensor uses a highly integrated process to integrate the PVDF piezoelectric film, sensitivity temperature compensation element, temperature sensing element, and signal conditioning circuit in the sensor. After receiving the pressure signal, it is amplified and filtered by the modulation circuit and transmitted to the buffer amplifier circuit for shaping and amplification. The B-terminal signal is at a low level, and after inversion, the B-terminal signal is 1. At this time, whether the NAND gate M can flip depends on the change of the sensor signal. The human body induction sensor keeps the suspension oscillation and constant temperature circuit always working in the normal state when it senses the human body signal. When the human body leaves, the vibration circuit and the constant temperature circuit are in the READY state.The control principle of the circuit of the present invention is very simple and stable. The ATmega2560 single-chip microcomputer control circuit chip, which is very common in the market, is adopted. The change of barium agent concentration is transmitted through the emission and reception of multiple sensors and infrared light-emitting diode arrays, so as to control the operation of the motor and keep the barium agent in a normal suspended state during this gastrointestinal examination, thus ensuring that the barium agent is in the best effect of assisting diagnosis.

[0023] As a preferred technical solution of the present invention, a lithium battery module can be added, which will significantly enhance the portability and power supply sustainability of the device. The lithium battery module is mainly responsible for providing stable power supply for components such as the control system, sensors and display screen, so as to ensure that the device can still work normally in case of power failure or unstable external power supply. In addition, the lithium battery module will be directly connected to the control circuit, and the monitoring and regulation of the power supply voltage will be realized through the ATmega2560 single-chip microcomputer control circuit to ensure that each functional module obtains the required voltage and current. The lithium battery can also form a closed-loop system with the charging module to ensure the efficient charging and power reserve of the battery, further improving the reliability and service life of the device.

[0024] After adding the lithium battery module on the basis of the existing device, the advantages of the device have been further improved. First of all, the addition of the lithium battery enables the device to still maintain continuous operation in case of power failure or mobile operation, greatly improving the stability and reliability of the system. In addition, the lithium battery can realize intelligent charging and discharging through the built-in power management module, which not only extends the service life of the battery, but also optimizes the energy consumption management, making the device more energy-efficient and high-efficient during long-term use.

[0025] During the use process, the lithium battery module is seamlessly integrated with the original intelligent control system, sensor module and display screen module to ensure that the device can quickly respond to various changes in working states while operating efficiently, further improving the intelligent level of the device. At the same time, the high energy density of the lithium battery enables the device to provide stable power for a long time on the premise of maintaining portability, thus enhancing the portability and use convenience of the device. This optimized design enables the device not only to adapt to diverse working environments, but also to significantly reduce the failure risk caused by external power problems, ensuring the excellent performance of the device in various application scenarios.
