[0058] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0059] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0060] In order to simplify the drawings, each figure only schematically shows the parts related to the present invention, which do not represent the actual structure of the product.

[0061] Figure 1 The present invention is a flowchart diagram for explaining an exemplary implementation of a method for detecting a medical device. Figure 2 This is a diagram for explaining an implementation example of a method for detecting medical equipment. Figure 1 and Figure 2 The medical device includes a housing 50 and a functional unit 60 disposed inside the housing 50, and the functional unit 60 includes a functional component 61. In an exemplary embodiment, the functional unit 60 is a circuit board including electronic components such as resistors and capacitors, and the functional component 61 is an electronic component on the circuit board. The detection method includes the following steps:

[0062] Step S10: An image acquisition device 10 capable of acquiring real-time image information of the functional unit 60 is arranged in the housing 50. The image acquisition device 10 may be a wide-angle camera, and the shooting range may cover the entire functional unit 60.

[0063] Step S40: Save the original image information of the functional unit 60 as a reference image.

[0064] In the original image information of the functional unit 60 , the functional component 61 has a good appearance, which is used for comparison during detection. The original image information is usually collected when the functional unit 60 is in a factory state or just after being repaired.

[0065] Step S50: When the medical device is inspected, the image acquisition device 10 is used to acquire real-time image information of the functional unit 60 and save it as an inspection image.

[0066] In the real-time image information of the functional unit 60, the functional component 61 usually changes in appearance after being damaged, for example, the color becomes black or white, and the pins fall off and are missing.

[0067] Step S60: using image recognition technology to compare the reference image and the detection image, and generating detection result information according to the comparison result.

[0068] Figure 3 FIG. 1 is another example diagram for explaining a method for detecting a medical device. Figure 3 , the reference image P1 and the detection image P2 are input into an information processing unit 20, which is a computer or tablet computer running an image recognition program. The image recognition program compares the pixel differences between the reference image P1 and the detection image P2, and generates detection result information based on the comparison results.

[0069] Figure 4 This is a partial flow chart for explaining the detection method of medical equipment. Figure 4 In an exemplary embodiment, step S60 specifically includes the following steps:

[0070] Step S61: using image recognition technology to locate the coordinate information of each functional component 61 of the functional unit 60 on the reference image P1, generating and saving a coordinate information comparison table of the functional component 61.

[0071] Step S63: using image recognition technology to compare the reference image P1 and the detection image P2 to determine whether there is a difference between the reference image P1 and the detection image P2.

[0072] Step S64: If the answer is yes, the coordinate information of the location of the difference is located and saved as the difference coordinate information.

[0073] Step S65: querying the coordinate information comparison table according to the difference coordinate information to obtain the functional components 61 with different appearances.

[0074] The detection method of medical equipment provided by the present invention collects real-time image information of the functional unit 60 by arranging an image acquisition device 10 in the housing 50, and uses image recognition technology to compare the original image information of the functional unit 60 with the collected real-time image information to find out the functional components 61 with different appearances. The detection method does not require disassembly of the housing 50, and improves the recognition accuracy of the appearance of the functional component 61, saving detection time and labor costs.

[0075] Figure 5 FIG. 1 is a flow chart for illustrating another exemplary embodiment of a method for detecting a medical device. Figure 5 , Figure 5 The detection method in the exemplary embodiment of Figure 1 The same or similar detection methods are not described in detail here, but the difference is that the detection method further includes the steps of:

[0076] Step S20: A lighting device 30 is arranged in the housing 50, and the lighting device 30 can illuminate the functional unit 60 when the image acquisition device 10 acquires real-time image information of the functional unit 60. The lighting device 30 can be a flashlight, or it can be in a closed state at ordinary times and turned on only when the image acquisition device 10 acquires an image, so as to improve the quality of the image acquired by the image acquisition device 10 by supplementing the light source.

[0077] Step S30: a wireless communication module 40 is provided in the housing 50, which can wirelessly transmit the real-time image information collected by the image acquisition device 10 to the outside of the housing 50. By means of the wireless communication module 40, the image acquisition device 10 and the information processing unit 20 can communicate wirelessly, which not only avoids the wired connection from damaging the closedness of the housing 50, but also removes the spatial restriction on the information processing unit 20.

[0078] Step S70: Upload the test result information via the Internet. The test result information can be uploaded to the server or terminal 80 to facilitate the manufacturer's engineers to read it remotely and then determine whether it is necessary to send a replacement functional unit 60 or functional component 61 to the on-site customer.

[0079] Figure 6 FIG. 1 is a partial flow chart for illustrating another exemplary embodiment of a method for detecting a medical device. Figure 6 , Figure 6 In the exemplary embodiment, step S60 and Figure 4 The same or similar parts as step S60 in the above are not described in detail, except that step S60 further includes the following steps:

[0080] Step S62: According to the coordinate information comparison table, the detection image P2 is adjusted using image recognition technology so that the coordinate information of each functional component 61 on the reference image P1 and the detection image P2 corresponds. Specifically, several functional components 61 can be selected as calibration points, and after obtaining the coordinates of the calibration points, the reference image P1 or the detection image P2 is scaled and rotated so that the coordinate information of each functional component 61 on the reference image P1 and the detection image P2 corresponds, thereby achieving automatic positioning.

[0081] Step S66: If the judgment is no, determine whether to update the reference image P1 according to a preset command. After one detection, it can be determined whether to replace the reference image P1 with the detection image P2 saved in the current detection process and use it for the next detection.

[0082] Step S67: If the judgment is yes, the reference image is updated. Specifically, the reference image is replaced with the detection image saved in the current detection process and used for the next detection. The reference image is updated sequentially with the detection to improve the accuracy of the next detection process.

[0083] Step S68: Mark and generate a prompt image P3 on the detection image P2 according to the difference coordinate information.

If so, the coordinate information of the difference is located and saved as the difference coordinate information, and the coordinate information comparison table is queried based on the difference coordinate information to obtain the functional component 61 with a difference in appearance.
