Description

Technical Field

[0001] This invention relates to the field of puncture image analysis technology, specifically to a pediatric venous puncture image analysis system and analysis method. Background Technology

[0002] Pediatric venipuncture is a medical procedure used for intravenous infusion or blood collection. Healthcare professionals first reassure the child, then select a suitable and easily visible vein, usually on the back of the hand or forearm. After disinfection, a fine needle is quickly and accurately inserted using specialized techniques to ensure successful blood flow on the first attempt, minimizing the child's discomfort.

[0003] Children's blood vessels are smaller and less stable than adults', and they may move due to fear or discomfort, making accurate puncture more difficult. Current equipment and techniques struggle to display the needle's position accurately in real time, leading to potential misjudgments by doctors and increasing the risk of perforation. Perforation not only causes additional physical pain for the child but can also trigger a series of complications such as hematoma, infection, and even the need for further surgical intervention. Therefore, there is an urgent need to develop a new technology that can precisely guide the needle and monitor its tip position in real time to improve puncture safety, reduce complications, and protect children's health.

[0051] To better understand the technical content of this invention, specific embodiments are provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0052] See Figure 1 This invention provides a pediatric intravenous puncture image analysis system, comprising: a puncture trajectory acquisition module for acquiring images of a puncture object being penetrated by a puncture object; an image calculation module for calculating the spatial value between the puncture object and the inner wall of the puncture object based on the image; a calculation processing module for comparing the spatial value of the puncture object inside the puncture object with a preset value, and if the spatial value is less than the preset value, issuing a stimulation signal; and a warning notification module for amplifying the stimulation signal in a signal amplifier and amplifying the stimulation signal through a display unit.

[0053] It should be noted that the subject of the puncture is a child. The puncture object is the puncture needle. During the puncture, the puncture needle is inserted into the child's body tissue, that is, the puncture needle is inserted into the child's blood vessel.

[0054] Specifically, the puncture trajectory acquisition module is placed on the corresponding skin of the puncture target, and the puncture material is inserted into the tissue of the puncture target, thereby acquiring an image of the puncture target as the puncture material penetrates its interior. The image calculation module calculates the spatial value between the puncture material and the inner wall of the puncture target based on the image, obtaining the distance between the puncture material and the tissue. The calculation processing module compares the spatial value of the puncture material inside the puncture target with a preset value. If the spatial value is less than the preset value, a stimulation signal is issued; if the spatial value is greater than the preset value, the puncture proceeds normally. After receiving the stimulation signal, the warning notification module amplifies the stimulation signal in a signal amplifier and amplifies the stimulation signal through a display unit. This solves the technical problem that existing equipment and technology cannot display the position of the puncture needle in real time and accurately, which leads to easy misjudgment by doctors during operation and increases the risk of perforation of the blood vessel wall.

[0055] In this embodiment, the puncture trajectory image module includes: an array camera unit for acquiring real-time images of the location, diameter, and wall thickness of the vein inside the puncture object; and a data transmission unit for transmitting the images to the real-time images via a Wi-Fi network, wherein the real-time images include first transmitted image content and second transmitted image content.

[0056] The array camera unit consists of multiple ultrasound probes, each coated with a gel at its skin-contacting end. This gel helps the probe make better contact with the skin, allowing ultrasound waves to propagate smoothly between the probe and the body. The ultrasound probes can acquire real-time images of the location, diameter, wall thickness, and blood flow status of veins in children, facilitating subsequent analysis. These real-time images are transmitted via a Wi-Fi network. The first transmitted image is of the puncture needle, and the second image is of the blood vessels and soft tissue. The Wi-Fi network can then transmit both images to the next node, improving transmission efficiency.

[0057] Furthermore, it also includes an image processing unit, which is used to receive the first transmitted image content and the second transmitted image content, correct the blur value of the first transmitted image content or the second transmitted image content using a nonlinear filtering method according to the blur value of the first transmitted image content or the second transmitted image content, and transmit the processed first transmitted image content or the second transmitted image content to the computing processing module.

[0058] After receiving the first and second transmitted image contents through the image processing unit, if the first or second transmitted image contents transmitted by the data transmission unit contain speckle noise, making it impossible to clearly see the edges and objects, and the image content is below a preset blur value within the image processing unit, then a nonlinear filtering method is used to correct the blurred first or second transmitted image contents, making them clearer for subsequent image calculation module analysis. When using the nonlinear filtering method, a median filtering window size of 3×3 or 5×5 is used for the first or second transmitted image contents. This can effectively preserve the edge information of veins while removing noise, thus making the blurred image content clearer.

[0059] In this embodiment, the image calculation module includes: an image receiving unit for receiving transmission data from the puncture trajectory acquisition module; and a calculation and analysis unit for analyzing the transmission data received by the image receiving unit, wherein spatial values ​​of the transmission data are extracted using three-dimensional point cloud data, and the spatial values ​​are a first content value and a second content value.

[0060] After receiving the first and second transmitted image contents processed by the image processing unit, the image receiving unit can obtain clear image data. The calculation and analysis unit extracts point cloud data based on the first and second transmitted image contents.

[0061] In one example, point cloud data is created for the puncture needle based on the content of the first transmitted image, resulting in a first content value. First, the initial value of the puncture needle within the blood vessel is initialized. This initial value is the threshold of the ultrasound acquisition probe, set to 120. If the echo value obtained by the ultrasound probe in the blood vessel exceeds 120, this position is determined as the location of the puncture needle, and three-dimensional coordinates x1, y1, and z1 are assigned. Multiple three-dimensional coordinates are obtained based on multiple echo values, thus determining the first content value within the puncture needle. Simultaneously, a second content value is determined for the content of the second transmitted image. Based on the aforementioned threshold, if it is below 120, either the first content value (x2), y2, or z2 is assigned as the second content value. Segmenting the first and second content values ​​using the PointNet++ model can better capture the local and global features of the point cloud, thereby improving the accuracy of classification and segmentation. When distinguishing between the puncture needle and vascular tissue, it can capture more detailed local features of the puncture needle and its relationship with the vascular tissue. Next, in the first and second transmitted image contents, the cylindrical simulated shape of the puncture needle is set using the least squares method, and multiple coordinates of the first content value are determined. Using n coordinate points, the direction of the central axis of the cylinder is estimated, and the angle of the puncture needle in the blood vessel is determined based on the direction of the central axis. The minimum value of the x-axis represents the leftmost position of the puncture needle in the left-right direction of the human blood vessel, and the maximum value represents the rightmost position. Similarly, the y-axis and z-axis represent the front-back or up-down distance. Based on this calculation, the distance between the puncture needle and the inner wall of the blood vessel is set to 1 mm. If it is less than 1 mm, it exceeds the warning line, and an alarm is sent to the warning notification module through a stimulation signal to prevent the puncture needle from damaging the inner wall of the blood vessel.

[0062] In this embodiment, the calculation processing module includes: a numerical judgment unit, used to set a preset value, and compare the preset value with the spatial value to obtain a first judgment signal and a second judgment signal, wherein the first judgment signal is that the spatial value is less than the preset value, and the second judgment signal is that the spatial value is greater than the preset value; and a signal triggering unit, used to activate the warning port of the warning notification module according to the first judgment signal, wherein the warning port amplifies the signal through the signal amplifier according to the first judgment signal, and amplifies the stimulus signal through the display unit.

[0063] The preset value is that the distance between the needle and the inner wall of the blood vessel is less than 1mm, such as 0.5mm. A first judgment signal is then generated. This signal triggers the warning port of the warning notification module. The warning notification module amplifies the first judgment signal through the signal amplifier and amplifies the stimulation signal through the display unit, including sound and flashing prompts.

[0064] Furthermore, when using point cloud technology to monitor the distance between the puncture needle and the blood vessel wall, the coordinates of the second content value can be used to observe the specific location and size of the contact area between the puncture needle and the nerve tissue, thereby preventing nerve injury complications.

[0065] In a preferred embodiment, the system further includes a teaching module, which receives data output by the computation processing module and saves it into a teaching collection. The teaching module provides a training module based on the teaching collection, and the training module generates an integral based on the training results and determines whether the result is qualified based on the integral.

[0066] After the puncture is completed, the point cloud data can be replayed and analyzed in detail. This is very helpful for teaching and skills improvement. Novice doctors or interns can learn correct puncture techniques and key operational points by observing the point cloud replay of the puncture process. The teaching collection includes multiple case studies based on actual puncture images, covering correct punctures, deviation punctures, and risky punctures. Novice doctors or interns complete puncture training based on this collection. After the training cycle ends, novice doctors or interns are awarded points for the number of risky and deviation punctures avoided in the trained items within the teaching collection. Higher scores result in fewer training cycles. The training module has a maximum score of 100; achieving 100 points is the standard for completing the training.
