Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to an optical diameter measuring device for a medical balloon. Background Art

[0002] With the development of medical technology, medical balloons are widely used in angioplasty, heart valve repair, urethral dilation and other fields. In order to ensure the safety and effectiveness of medical balloons, accurate size detection is required. Medical balloons are small expansion devices made of soft materials (such as polyurethane, silicone, etc.), mainly used to dilate narrow blood vessels or other body passages. Their design usually includes one or more balloons that can be inflated and deflated, and a catheter part for connecting to the delivery system. Depending on the application, medical balloons can have different shapes and sizes, ranging from a few millimeters to a few centimeters. The size of medical balloons is crucial to their function. For example, in angioplasty, a balloon that is too small may not be able to fully dilate the blood vessel, while a balloon that is too large may cause the blood vessel to rupture. Therefore, accurately measuring parameters such as the length, diameter, and maximum diameter of the balloon in the uninflated state is of great significance to ensure the effectiveness of the operation and the safety of the patient.

[0003] Therefore, it is necessary to design an optical diameter measurement device for medical balloons to ensure patient safety, promote the development of the medical device industry, product quality control, and the accuracy and reliability of clinical research and data analysis.

[0074] The working process of the medical balloon optical diameter measuring device of the present invention is as follows:

[0075] First, open the MVS software, connect the camera 51 to display the real-time image, place the ordinary shape balloon 81 on the balloon holder 4 (the special shape balloon 82 is placed on the additional balloon fixture 6 and connected to the slot of the balloon holder 4), and move the ordinary shape balloon 81 to the optimal imaging area between the imaging system 5 and the light source 56 by adjusting the vertical positioning mechanism 2 and the horizontal positioning mechanism 3 (during pressurized measurement, one end of the ordinary shape balloon 81 is sealed and the other end is connected to the air nozzle 72. After turning on the air pump 7 and setting the pressure through the pressure regulator 71, perform the same steps as below).

[0076] Then close MVS and open the balloon size detection software. According to the model of the ordinary shape balloon 81, make a corresponding balloon detection template (if there is a template created locally, you can directly read it) and recipe parameters. After the template is made, click to start detection. The camera 51 takes photos of the ordinary shape balloon 81 at different angles, and then uploads the photos to the system of the computer 9. The detection software performs size detection based on the uploaded pictures, calculates the size of the same balloon picture and compares it with the parameters in the set recipe. If it is within the parameter range, it is qualified, otherwise it is unqualified. After the measurement is completed, the measurement results are saved to the database.
