According to the ultrasonic imaging method and the ultrasonic equipment, bubbles in a target area of an ultrasonic image are detected, a bubble detection result is determined, whether an aeroembolism risk exists or not is judged according to the bubble detection result, and when it is judged that the aeroembolism risk exists, a user is prompted; the bubble level in the target area can be automatically given, and the user is prompted when the air embolism risk exists, so that automatic monitoring of the bubbles in the target area is realized.

The invention provides a vascular intervention surgical robot and a method for monitoring bubbles in a multi-ported valve of the vascular intervention surgical robot, and relates to the technical field of vascular intervention. The method comprises the following steps: acquiring an original image of a multi-way valve in a vascular interventional operation process; performing graying processing on the single-frame RGB image of the multi-ported valve to obtain a grey-scale map; performing edge extraction processing on the grey-scale map to obtain an edge feature map; performing color space conversion on the single-frame RGB image of the multi-ported valve to obtain a single-frame HSV image; pixel information of a V channel in the single-frame HSV image is extracted; judging a lumen region based on pixel information of a V channel in the extracted single-frame HSV image; on the basis of the edge feature map and the pipe cavity area, the occurrence condition of bubbles in the multi-way valve is judged; on the basis of the judged bubble occurrence condition in the multi-way valve, a bubble occurrence prompt is selectively sent out, so that a doctor can find bubble generation in time in the operation process and make corresponding treatment in time, and the operation risk caused by air embolism is avoided.

The invention relates to the technical field of infusion control systems, and provides a multi-channel intelligent infusion control system and method.In the multi-channel intelligent infusion control system, a central control unit cooperates with a liquid level detection module, an electric control switch valve and a dripping speed control module on each infusion channel; the technical problems that an existing infusion device cannot automatically recognize multiple bottles of liquid medicine, cannot conduct seamless switching in sequence and depends on manual intervention are effectively solved. The system can automatically identify the number and the positions of connected infusion bottles based on liquid level feedback, intelligently open a current channel and close other channels according to a preset sequence, cut off the current channel in time before liquid medicine is completely infused so as to prevent air from entering, and synchronously switch to a next infusion channel, so that unattended multi-bottle continuous infusion in the whole process is realized; the risk of air embolism is thoroughly avoided, the workload of frequent inspection and manual bottle replacement of nurses is remarkably relieved, and infusion safety, continuity and patient experience are improved.

The invention relates to the field of infusion, and discloses an infusion auxiliary device capable of collecting waste liquid. The device comprises a base, an infusion bag, a waste liquid collecting bottle and a liquid dropping cavity, the bottom end of the infusion bag is connected with the liquid dropping cavity through an infusion tube, the surface of one side of the liquid dropping cavity is connected with the waste liquid collecting bottle through a connecting tube, an upper connector and a lower connector are arranged at the upper end and the lower end of the liquid dropping cavity, and the upper connector and the lower connector are Luer connectors. An anti-reflux valve is arranged between the liquid dropping cavity and the lower connector, an exhaust assembly is arranged on the surface of the end, located in the liquid dropping cavity, of the connecting pipe, the infusion bag is connected with the liquid dropping cavity through an infusion pipe to provide a source for liquid medicine conveying, and the liquid dropping cavity serves as a liquid medicine transfer and observation core and is matched with the connecting pipe to achieve communication with a waste liquid collecting bottle. The problem of collection of residual liquid medicine and blood in the pipeline after infusion is solved, environmental pollution and treatment troubles are avoided, air in the pipeline can be exhausted through the exhaust assembly, and the risk of air embolism is avoided.

This invention provides a medical interventional catheter, comprising a first expandable body, a second expandable body, and a main body. Both the first and second expandable bodies are disposed at the distal end of the main body, with the first expandable body located inside the second expandable body. A first space is formed between the outer surface of the first expandable body and the inner surface of the second expandable body. The contrast agent disclosed herein is filled within the double-layered nested expandable body, facilitating observation of the expandable bodies' state within the body via a display device. This floating catheter is effectively compatible with existing contrast agents, reducing the learning curve for operators. In the event of accidental rupture of the first expandable body, the gas inside can enter the second expandable body, preventing direct gas entry into the bloodstream and mitigating the risk of air embolism, thus improving catheter safety.

The application discloses a hemodialysis circulating pipeline, which comprises an arterial pipe and an arterial pot installed on one side of the arterial pipe, the outer wall of the arterial pipe is uniformly connected with a plurality of auxiliary pipes, the top end of the auxiliary pipe is provided with a sealing mechanism, and a buffer pot is installed on the top of the auxiliary pipe for reducing instantaneous impact during liquid supplementing, and the application relates to the technical field of dialysis pipeline. The hemodialysis circulating pipeline has the advantages that the joint anti-loosening performance is improved compared with the traditional conical surface friction joint through the triple anti-loosening mechanism of the axial thread fastening of the external connection fixing mechanism, the end surface elastic sealing and the anti-skid point static friction, the joint effectively resists the low-frequency vibration of a dialysis machine and the continuous pulling of a patient, and the double structure of the elastic clasp axial locking and the steering protrusion circumferential locking of the steering limiting mechanism is matched, the joint anti-pulling-off force is further improved, the serious safety hazards such as blood leakage and joint collapse are fundamentally eliminated, and the risks of patient blood loss and air embolism are avoided.
