Embodiment 1

[0047] Example 1: The calibration system of this embodiment is used for aperture calibration, and the light source group 210 inside the housing is used as a standard light source to emit light through the near-infrared camera 111 of the microcirculation imaging neurophysiological detection device 1 itself for detection, such as image 3 shown, including the following steps:

[0048] Step 1. First, use the input power supply 270 to input the 12V power supply, turn on the power switch 260, and drive the moving parts of the guide rail to move the light source group 210 from the top of the casing to one end of the casing, turn on the light source power source 250, and make the light source group 210 emit light. Incident to the central area of ​​the target drawing board 240, the monitoring device 220 obtains the brightness of the light reflected back on the central area of ​​the target drawing board 240;

[0049] Step 2: Determine by the display device 230 whether the brightness ob...

Embodiment 2

[0051] Example 2: The calibration system of this embodiment is used for light source calibration. The light emitted by the LED near-infrared light source of the monitoring device 220 and the microcirculation imaging neurophysiological detection device 1 is used to illuminate the target plate, and then the reflected brightness signal It is displayed in the form of numbers on the display, such as Figure 4 shown, including the following steps:

[0052] Step 1. First, use the input power supply 270 to input the 12V power supply, turn on the power switch 260, and drive the moving parts of the guide rail to move the light source group 210 from one end of the housing to the top of the housing;

[0053] Step 2: Place the lens of the near-infrared camera 111 of the microcirculation imaging nerve electrophysiology detection device 1 at the opening at one end of the housing, turn on the power of the microcirculation imaging nerve electrophysiology detection device 1, and start the micro...

Embodiment 3

[0056] Example 3: The calibration system of this embodiment is used for focus calibration, the monitoring device 220 is used to monitor the position of the laser pointer in the target plate area, and the adjustment screw of the laser tube mounting seat of the microcirculation imaging neurophysiological detection device 1 is adjusted so that 2 The bright spots overlap in the center frame of the target plate, such as Figure 5 shown, including the following steps:

[0057] Step 1. Drive the moving parts of the guide rail to move the light source group 210 from one end of the housing to the top of the housing;

[0058] Step 2: Place the lens of the near-infrared camera 111 of the microcirculation imaging nerve electrophysiology detection device 1 at the opening at one end of the housing, turn on the power of the microcirculation imaging nerve electrophysiology detection device 1, and start the microcirculation imaging nerve electrophysiology detection. device 1;

Abstract

A medical device calibration method, which ensures the consistency, accuracy and safety of optical parameters and image acquisition parameters of a microcirculation imaging nerve electrophysiological detection device that leaves the factory, belongs to the technical field of calibration, and the method is implemented based on a calibration system, the system comprising a shell body, light source group, monitoring device, display device, target drawing board and light source power supply; the light source group, monitoring device, target drawing board and light source power supply are all arranged in the casing, the light source group is arranged at one end of the casing, and one end of the casing is also provided with The opening is used to place the lens of the near-infrared camera. The target drawing board is arranged at the other end of the casing. The target drawing board is used to receive and display the light emitted by the light source group and the LED near-infrared light source. The monitoring device is used to obtain the target drawing board. The image is sent to a display device for display, the display device is arranged outside the casing, and the light source power supply is used to provide power for the light source group. Aperture calibration, light source calibration, focus calibration and lens focal length calibration are realized by the system.

Description

technical field [0001] The invention relates to a calibration method for medical instruments, in particular to a calibration method for a microcirculation imaging nerve electrophysiological detection device, and belongs to the technical field of calibration. Background technique [0002] In the early stage of diabetes, people do not pay enough attention, which often leads to delay in the discovery of the disease and delay in treatment. Diabetic foot is one of the common complications of diabetes, so it can be detected by early screening of diabetic foot so that early foot lesions can be detected before the onset of the disease. In the process of diagnosis and treatment of diabetes, the method of blood collection is widely used. For patients with diabetes, frequent blood collection is time-consuming and laborious, and due to the characteristics of diabetes, the wound after blood collection is not easy to heal. [0003] In order to overcome the problem of frequent blood colle...
