This invention discloses a pericardial effusion puncture and drainage device with angle adjustment, including an installation mechanism, a support mechanism in the middle of the installation mechanism, and an isolation mechanism at the top of the installation mechanism. A puncture mechanism is located in the middle of the support mechanism, and clamping assemblies are fixed at both ends on one side of the support mechanism. A tube guide mechanism is located on one side of the puncture mechanism. This invention utilizes the cooperation between the support mechanism and the puncture mechanism on the installation mechanism. A first worm gear in a first adjustment box drives a first worm wheel, and a second worm gear drives a second worm wheel, which in turn drives a large gear via a small gear. During puncture, the doctor can flexibly adjust the puncture position and finely adjust the puncture angle according to the patient's condition, avoiding prolonged holding of the puncture device, freeing the doctor's hands, ensuring a stable puncture process, making the operation more convenient for the doctor, and improving work efficiency.

Cannabidiol, or a pharmaceutically acceptable prodrug, derivative, salt, or solvate thereof, for use in treating or preventing recurrent pericarditis is disclosed. The effectiveness of cannabidiol in attenuating the levels of interleukin-1β (IL-1β) and IL-6, and the transcription of pro-IL-1β and NLRP3 mRNA in in vitro models are disclosed. Also disclosed are experiments showing cannabidiol to be effective in preventing an increase in the pericardial space (which is an indicator of pericardial effusion) and the pericardial thickness in an in vivo mouse model of pericarditis.

The present application relates to a kind of visible pericardial effusion puncture device, belong to medical instrument field, the present application is integrated in the inside of puncture needle, it is beneficial to produce smaller wound, it is beneficial to the recovery of patient after operation.Simultaneously, by support piece, endoscope is firmly fixed in the inside of puncture needle, avoid the shaking of endoscope when puncture, influence doctor operation.Using the structure setting of the elasticity of support piece and its left abutment portion includes left arc segment, left horizontal section and left vertical section, right abutment portion includes right arc segment, right horizontal section and right vertical section, it can realize stable position locking, and no longer need as commonly used Y type or T type support structure, to reduce the space occupied by support piece, so as to leave sufficient effusion extraction space at opening, while reducing wound, reduce the possibility of pericardial effusion block.

The application discloses a method and device for judging pericardial effusion by using a heart ultrasound video responsibility frame, and the method comprises the following steps: collecting a heart ultrasound standard section video, unifying a format, and training a static image classification neural network model by using the heart ultrasound standard section video; building a pericardial effusion judgment model based on the static image classification neural network model, inputting a heart ultrasound standard section video to be identified into the pericardial effusion judgment model; the pericardial effusion judgment model outputs a feature matrix of the video, a random forest model is used to calculate the feature matrix of the video to obtain a feature importance matrix of the video, a responsibility frame used for video benign and malignant judgment is selected based on information entropy reduction and the feature importance matrix of the video; and the static image classification neural network model outputs whether the heart ultrasound video has pericardial effusion based on the responsibility frame used for video benign and malignant judgment. The application can realize automatic identification of whether there is pericardial effusion in an ultrasound heartbeat video.
