Specific embodiments

[0015] The following further describes the embodiments of the present invention in detail in conjunction with the examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0016] An instrument for detecting the nature of pleural effusion mainly consists of a probe, a signal processing module, a data analysis module, a display module, a database module and a data transmission module. The probe is connected to the signal processing module through a signal line, the signal processing module is connected to the data analysis module, and the data analysis module is respectively connected to the display module, the database module and the data transmission module.

[0017] The probe is made of a flexible material that can be bent, with a length not exceeding 20 cm and a diameter not exceeding 5 mm. It integrates an ultrasonic sensor, a temperature sensor and a pH sensor inside. When in use, the probe is inserted into the pleural effusion site of the patient. The ultrasonic sensor measures the density of the effusion by transmitting and receiving ultrasonic signals, the temperature sensor measures the temperature of the effusion, and the pH sensor measures the pH value of the effusion.

[0018] The signal processing module includes a signal amplifier and a filter. The signals collected by the probe are usually weak and may contain noise interference. The signal amplifier amplifies the collected signals, and the filter filters the amplified signals to remove noise interference and improve the quality and stability of the signals. The processed signals are transmitted to the data analysis module for analysis.

[0019] The data analysis module analyzes the processed signals based on a preset algorithm. This algorithm combines the nature data of various effusions stored in the database module and judges the nature of the effusion through comparison and analysis. For example, according to parameters such as the density, temperature and pH value of the effusion, it is judged whether the effusion is an exudate or a transudate, and whether there are infections, tumors, etc.

[0020] The display module is used to display the detection results, including information such as the nature of the effusion, density, temperature, pH value, etc. The display module can use devices such as liquid crystal displays to present the detection results to medical staff in an intuitive and clear manner.

[0021] The database module stores a large amount of effusion property data, which includes information such as the physical parameters and chemical properties of pleural effusion caused by different etiologies. When analyzing the processed signals, the data analysis module will compare the collected data with the data in the database to improve the accuracy of judgment.

[0022] The data transmission module transmits the detection data to the hospital system through Bluetooth or Wi-Fi connection. The hospital system can store, analyze, and manage these data to achieve data sharing and remote monitoring. At the same time, the instrument supports long-term storage and historical query of detection data, and medical staff can view the patient's historical detection data at any time to understand the changes in the condition.

[0023] The working method of the pleural effusion property detection instrument of the present invention is as follows: Probe insertion: Medical staff slowly insert the probe into the pleural effusion site of the patient, paying attention to gentle operation to avoid unnecessary damage to the patient.

[0024] Parameter acquisition: The ultrasonic sensor, temperature sensor, and pH sensor in the probe start to acquire physical parameters such as the density, temperature, and pH value of the effusion.

[0025] Signal processing: The collected signals are transmitted to the signal processing module, and the signal processing module amplifies and filters the signals and converts them into analyzable data.

[0026] Data analysis: The data analysis module receives the processed data and analyzes it in combination with the data stored in the database module. Through preset algorithms for comparison and analysis, the nature of the effusion is judged.

[0027] Result display: The analysis results are output through the display module, and medical staff can intuitively view information such as the nature, density, temperature, and pH value of the effusion.

[0028] Data transmission and storage: The detection data is transmitted to the hospital system through the data transmission module to achieve data sharing and remote monitoring. At the same time, the instrument internally stores the detection data for a long time and supports medical staff for historical query.

[0029] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art.
