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.

The invention provides application of vitamin C in preparation of a medicine for treating 1-naphthol poisoning, and belongs to the technical field of biological medicine. Research finds that vitamin C can effectively relieve animal development retardation caused by 1-naphthol and can also effectively treat animal pericardial edema caused by 1-naphthol, so that vitamin C has the effect of treating 1-naphthol poisoning.

The invention relates to a visual hydropericardium puncture device, which belongs to the field of medical instruments, and integrates an endoscope in a puncture needle, thereby being beneficial to the generation of a smaller wound and the postoperative recovery of a patient. Meanwhile, the endoscope is firmly fixed in the puncture needle through the supporting piece, and the situation that the operation of a doctor is affected due to the fact that the endoscope shakes during puncture is avoided. By means of the elasticity of the supporting piece and the structural arrangement that the left abutting portion of the supporting piece comprises the left arc section, the left horizontal section and the left vertical section and the right abutting portion of the supporting piece comprises the right arc section, the right horizontal section and the right vertical section, stable position locking can be achieved, a common Y-shaped or T-shaped supporting structure is not needed any more, and therefore the space occupied by the supporting piece is reduced; therefore, a sufficient hydrops extraction space is left at the opening, and the possibility of pericardium hydrops blockage is reduced while the wound is lowered.

The embodiment of the specification provides a dynamic cardiac tamponade prediction method, device, medium and program product based on multi-modal continuous monitoring data, and relates to the field of intelligent medical treatment. The method comprises the following steps: receiving pericardial effusion related physiological data including at least ultrasonic parameters, electrocardio parameters, body surface temperature parameters and clinical sign data of a sample; extracting a current effusion volume parameter in real time according to the ultrasonic parameters, and calculating an effusion growth rate per unit time; quantitatively extracting a heart rate value, a percentage of a decrease amplitude of a QRS complex amplitude relative to a baseline and an alternating change type of the QRS complex amplitude according to the electrocardio parameters; analyzing a temperature change trend according to the body surface temperature parameters; inputting the effusion growth rate, the quantitative electrocardio parameters, the temperature change trend and the clinical sign data into a preset multi-modal fusion scoring model to output a real-time comprehensive risk score; and generating a dynamic early warning signal of a corresponding level according to the real-time comprehensive risk score to realize a prior prediction of a risk of cardiac tamponade.

A percutaneous pericardial puncture assembly and system, the percutaneous pericardiopuncture assembly comprises a puncture tube and a puncture piece, the puncture tube comprises a tube body and a puncture section arranged at the distal end of the tube body. A puncture channel, a negative pressure suction channel and an imaging channel are arranged in the tube body, and are communicated with the working port at the distal end of the puncture section. The imaging module is arranged in the imaging channel to realize real-time visualization of the in-vivo puncture operation; the proximal end of the negative pressure suction channel can be connected to a negative pressure suction device to provide negative pressure for the working port and then adsorb the pericardial wall layer; the puncture piece is arranged in the puncture channel and can puncture the adsorbed pericardial wall layer. By arranging the negative pressure suction channel, the pericardial wall layer can be captured before the puncture piece punctures, so that even if only a small amount of pericardial effusion exists between the pericardial wall layer and the pericardial visceral layer, the medical staff can also complete the puncture of the pericardial wall layer without damaging the pericardial visceral layer, the operation is simple, and the safety and success rate of percutaneous pericardial puncture under full indications are greatly improved.
