When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0032] Reference Figure 1-10 The present invention discloses an intelligent blood sampling device for venous blood sampling, including a blood sampling frame 100. In the present embodiment, the blood sampling frame 100 includes a receiving box 101, a hand receiving piece 102 arranged on the receiving box 101, and a protective component 103 arranged in the hand receiving piece 102; the receiving box 101 is placed on the desktop as a whole, and its overall size is similar to that of an existing automatic blood pressure measuring device. The whole is made of hard plastic, and a cavity is opened inside. The hand receiving piece 102 is arranged inside, and an opening is arranged on the hand receiving piece 102. The operator puts his hand into the hand receiving piece 102 and uses the internal structure to collect blood. In order to facilitate observation, the receiving box 101 adopts a transparent structure as a whole, and the receiving box 101 is a split type, which is connected by bolts and can be disassembled for maintenance at any time.

[0033] Furthermore, the present invention also includes a blood collection component 200, which includes a pressurizing component 201 arranged on the hand receiving component 102, a blood collection component 202 arranged on the hand receiving component 102, and a needle extension component 300 arranged on the blood collection component 202. The pressurizing component 201 can seal the opening on the hand receiving component 102, and a blood storage component 204 is arranged at the rear end of the blood collection component 202. In this embodiment, the blood storage component 204 includes an existing blood collection tube, which is a commonly used medical blood collection tube with an open end.

[0034] Furthermore, an intelligent control module 104 is provided on the receiving box 101. In the present embodiment, the intelligent control module 104 is mainly used for monitoring the current blood collection volume, collecting the current patient's arm extension position, the patient's venous blood vessel position, calibrating the collection position and other related intelligent information collection, and for entering the patient information and collecting the information in a unified manner in combination with the patient's previous medical condition.

[0035] Furthermore, in the present embodiment, the hand receiving member 102 includes a receiving ring 102a arranged on the receiving box 101, a hand supporting pad 102b arranged in the receiving ring 102a, and a blood vessel identification component 104 arranged on the receiving ring 102a. The receiving ring 102a is arranged vertically and is in a ring shape as a whole. The annular receiving ring 102a is connected to the receiving box 101, and the hand supporting pad 102b is in the shape of an arc-shaped plate, which is connected to the receiving ring 102a and extends into the receiving box 101, so that after the operator extends his arm into the receiving ring 102a, the hand supporting pad 102b can be placed on the hand supporting pad 102b. The cross-section of the hand supporting pad 102b is a semicircular arc, and the whole is inclined to adapt to the natural flat bending angle of the arm.

[0036] Furthermore, in this embodiment, the blood vessel identification component 104 includes an irradiating element 104a disposed on the receiving ring 102a, a near-infrared auxiliary ray gun 104b disposed on the irradiating element 104a, and a camera disposed on the irradiating element 104a, and the camera is connected to the intelligent control module 104.

[0037] Before blood sampling, the irradiation element 104a first irradiates the entire arm to maintain the brightness inside the receiving box 101, and then uses a near-infrared auxiliary ray gun to focus on irradiating the position of the elbow to scan the blood vessels at the current position, and then uses a camera to photograph the current irradiated blood vessel position and transmit it to the intelligent control module 104 for identification.

[0038] A clear blood vessel texture image is collected through the blood vessel texture image acquisition circuit. Active near-infrared light irradiates the part where the blood vessel texture is to be collected to obtain a clearer blood vessel texture image with sharper edges, which is convenient for the next step of image preprocessing. Preprocessing of image texture: Use standard deviation threshold tracking method to separate the background and determine the foreground and background of the image. Since the vascular texture of the image is composed of black and white lines, the grayscale changes greatly and has a large standard deviation; while the grayscale distribution of the background is relatively flat and the standard deviation is small, so the standard deviation of a group of pixels centered on each point is calculated. When the standard deviation is greater than a certain threshold, it can be determined that the point is the foreground, otherwise it is the background. Then perform binary denoising and thinning. Thinning is to convert the line segments of the texture image into the width of a single pixel and maintain the original continuity; Singular point detection: Find the singular points, the locations of the ends and branch points of the vascular thinning lines of the vascular texture image, and the points with larger vascular curvature, and transform the vascular texture authentication problem into a point pattern matching problem; Eight adjacent points are used to extract feature points from the binary vascular texture image. This method uses "1" to represent the line segment and "0" to represent the background. The eight adjacent points X1, X2, X3, X4...X8 (as shown in the figure above) of the test point (m, n) are compared cyclically. If "0" and "1" change 6 times, the test point is a branch point. If it changes 2 times, it is the end point of the thinning line. The point with the larger curvature of the blood vessel can be derived by taking the derivative of the line segment, and then the position of the blood vessel can be accurately located.
