Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a positioning and measuring device based on a zone intramural method (ZIM). Background Art

[0002] When PICC is placed, the nurse needs to measure the patient's arm to determine the length of the catheter to the superior vena cava after it is placed in the vein. The positioning method is: the patient lies flat, the upper limb on the puncture side is abducted to form a 90-degree angle, starting from the antecubital fossa of the patient's elbow joint, along the vein, across the shoulder to the right edge of the superior sternal notch, located at the upper end of the sternal manubrium, and then folded downward to the third intercostal space (using the sternal angle as a mark to determine the second intercostal space and then measure downward to the third intercostal space). Finally, the distance from the puncture point to the antecubital fossa is subtracted to obtain the appropriate length of the catheter. At this time, the end of the catheter is located in the superior vena cava segment.

[0003] At present, some catheter placements in clinical practice use the "blind puncture method", that is, the puncture point and the insertion depth of the puncture catheter are determined by the nurse's measurement. Specifically, when PICC catheterization is used, the blind puncture method is used, which has hidden dangers in determining the puncture position, reduces the success rate of puncture, and increases complications such as phlebitis, thrombosis, soft tissue injury, ectopic position and infection. In addition, before PICC catheterization, the length from the proposed puncture position to the superior vena cava needs to be measured; during the puncture process, once the puncture position is determined, the nurse needs to measure again and determine the length of the inserted catheter. During the measurement process, there are problems such as manual measurement errors and contamination of the sterile area.

[0004] With the development of PICC technology, the application of ultrasound-guided MST PICC placement has become more and more widespread. Some medical institutions have also carried out "ultrasound-guided PICC placement", which reduces the incidence of complications such as phlebitis, thrombosis, soft tissue injury, catheter malposition and infection compared with blind insertion. At present, studies have shown that (Dawson, Robert B. PICC Zone Insertion MethodTM (ZIMTM): A Systematic Approach to Determine the Ideal Insertion Site for PICCs in the Upper Arm [J]. Journal of the Association for Vascular Access, 2011, 16 (3): 156, 162-160, 165.) The regional puncture method ZIM can guide PICC placement, facilitate nurses to find the accurate puncture site, and reduce the occurrence of PICC-related complications. However, there is little research on ZIM in China.

[0005] A search of existing patents shows that no one has yet developed a relatively more accurate and rapid positioning and measurement device for regional puncture ZIM catheterization.

[0006] Therefore, in summary, there is an urgent need for a lighting light bar device for PICC catheterization puncture location positioning and measurement based on the zone puncture method (ZIM), which can determine the best selection area for PICC puncture through evidence-based evidence, help nurses quickly determine the puncture area, save operation time, improve the success rate of puncture, and reduce related complications. However, there is no report on this new type of positioning and measurement device based on the zone puncture method (ZIM). Summary of the invention

[0011] In the above-mentioned positioning and measuring device based on the zone intravital puncture method (ZIM), as a preferred solution, a power supply is also provided inside the micro-operation host, and the lighting lamp and the camera device are electrically connected to the power supply inside the micro-operation host.

[0034] In this embodiment, the light source controller 7 is preferably capable of controlling the strip LED light 5 to simultaneously present red, green and yellow colors, and each of the presented colors presents an equal wavelength of a certain length. The light source controller 7 converts the color of the strip LED light 5 upon receiving the input signal from the micro-operation host, and displays the set red, yellow and yellow colors on the upper arm of the measured patient, and divides the patient's upper arm into three equal areas according to the color, and the presented colors are respectively located in the three areas.

[0039] The method of using the present invention is as follows: firstly, the device is set on the PICC catheter bed at a position corresponding to the patient, and then the power switch button on the micro-operation host is turned on, and the micro-operation host starts to control the camera device to operate, and the infrared scanning positioning device and the camera on the camera device perform a landmark scan on the target object, and the LED light supplement device performs light supplement, so that the read image information is clearer and more accurate, and then the storage device on the camera device outputs the read image data to the micro-operation host again, and the micro-operation host performs detection and analysis of the image data and calculates the final data result, and then the micro-operation host outputs the calculated data result to the lighting lamp, and controls The strip LED light on the lighting lamp presents different colors (red, green, yellow, and colorless) equidistantly on the patient's upper arm, and the micro-operation host calculates the midpoint of the patient's upper arm. According to the ZIM method, the midpoint to the intersection of green and yellow is taken as the optimal puncture area. After the PICC nurse determines the location of the puncture point, the micro-operation host measures the distance from the puncture point to the superior vena cava and the depth of PICC catheter insertion, and finally completes the entire measurement of the catheterization data. The entire catheterization measurement process will be intuitively displayed on the display of the micro-operation host, which is convenient for medical staff to observe and record, and also provides favorable assistance for subsequent nursing teaching and quality improvement.

[0040] It should be noted that the present invention is simple to operate and has strong practicality. It uses a machine vision system to replace manual measurement and judgment, and can quickly obtain data information of the detected target, helping nurses to quickly determine the puncture area, saving operation time, improving the detection efficiency of daily work, and reducing the occurrence of complications.
