4 results about "Internal bleeding" patented technology

The utility model discloses an internal fistula side limb fixer for a hemodialysis patient during defecation, which comprises a first fixing plate and a second fixing plate, a plurality of fixing seats are arranged on the first fixing plate and the second fixing plate, arc-shaped limiting rings are arranged on the fixing seats, and restraint straps are arranged in the arc-shaped limiting rings; shoulder straps are arranged at one ends of the first fixing plate and the second fixing plate. When the fixator is used, an internal fistula side limb can be placed in the fixator, and internal hemorrhage caused by excessive movement of the limb is prevented; the contact surface between the inner side of the fixator and the limbs is made of breathable perforated fabric which is comfortable and skin-friendly; a restraint strap and a first hook-and-loop fastener are arranged outside the fixator, the size of the fixator can be adjusted to be proper according to the size of the arm circumference of a patient, the shoulder strap is arranged, the limb on the internal fistula side can be kept in a straightened state when the patient goes to the toilet, and a puncture needle is better protected; the second hook-and-loop fastener can prevent the puncture needle from slipping due to the fact that the puncture needle is pulled when the patient goes to the toilet.

This invention provides a method and system for detecting the location of internal bleeding in the human body based on ultrasound images, belonging to the field of ultrasound detection technology. The method includes the following steps: constructing an image dataset using acquired ultrasound images containing bleeding points; constructing and training an improved neighborhood attention converter model based on the image dataset; acquiring the ultrasound image to be detected, using the trained improved neighborhood attention converter model to detect the bleeding location, and obtaining the detection result; and visualizing the detection result using a visualization tool. This invention applies deep learning networks to the detection of bleeding points in ultrasound images. With the support of the dataset, the deep learning network can achieve higher detection accuracy and better noise robustness compared to traditional algorithms. For the small target detection task of bleeding points, specific optimizations have been made at the network design level, resulting in a better detection rate.

The present application relates to the technical field of medical image processing, and discloses a method and system for predicting vascular injury and assessing internal hemorrhage risk, comprising: acquiring original data, wherein the original data includes body surface marker coordinate data, physiological state and trauma-related information of a critically injured trauma victim; preprocessing the body surface marker coordinate data in the original data to obtain standardized coordinate data; inputting the standardized coordinate data into a pre-trained graph neural network model for mapping processing to obtain vascular marker three-dimensional coordinate prediction data; calculating the spatial distance between the injury path and the vascular marker according to the vascular marker three-dimensional coordinate prediction data and the trauma-related information to obtain a quantitative evaluation result of vascular injury risk; and combining the quantitative evaluation result of vascular injury risk with the physiological state information of the victim to complete comprehensive quantitative assessment of the internal hemorrhage risk of the victim to obtain a corresponding risk level result.

This specification relates to an artificial hemostatic plug for stopping and / or preventing internal bleeding in a patient, more specifically, intrathoracic bleeding. The plug has a compressible plug body with a first end and a second end. The plug also has a thread slidably disposed through the plug body. The thread is also fixedly connected to the first end of the plug body, allowing the first end to be pulled toward the second end using the thread, which extends further outward from the plug body. This specification also includes a kit comprising the plug and a plug pusher.
