The present application relates to the technical field of medical physiological data processing, in particular to a kind of cardiac surgery ICU prognosis support system and method assisted by electronic medical record.The method determines category representative point after initial classification based on physiological data, i.e., the number of categories to be classified is determined using the relatively rough results obtained by initial classification.Furthermore, the initial postoperative abnormality difference between patient sample points and category representative points is corrected based on the initial classification results, and the final classification results of each sample point are determined using the corrected postoperative abnormality difference.The present application can make the corrected postoperative abnormality difference obtained finally more accurately represent the distance between sample points and category representative points, and then determine accurate classification results, which is convenient for medical staff to provide postoperative prognosis support for patients.

The application belongs to the technical field of medical equipment, and particularly relates to a drainage device for cardiothoracic surgery, which comprises a mounting shell, a storage part arranged in the mounting shell and used for storing the drained liquid, a fixing part arranged in the mounting shell and capable of extruding and fixing the storage part, a blocking part arranged at the upper end of the fixing part and capable of extruding and blocking the input end of the fixing part, a driving motor, a driving screw, a driving seat, a limiting seat, a rotating seat, a fixing cover, a negative pressure tank and an air pump. The driving motor is fixedly connected to the inside of the mounting shell, the driving screw is rotationally arranged in the inside of the mounting shell, one end of the driving screw is fixedly connected to the output end of the driving motor, the driving seat is slidingly arranged in the inside of the mounting shell, and the inside of the driving seat is threadedly connected to the outer edge of the driving screw. The application can drain the liquid in the patient's body through the drainage tube and conveniently replace the storage part after the storage is completed.

Antibodies which bind selectively to cardiac conduction system (CCS) cells, imaging and / or diagnostic reagents and compositions visualizing the CCS cells and therapeutic products and compositions comprising one or more of the antibodies. Methods for delivering therapeutic agents to the CCS cells. The disclosure further provides methods for visualizing the CCS cells in vivo in real time, including in a subject undergoing a cardiothoracic surgery or other cardiac intervention. Compositions and methods for isolation, purification, analyses and / or transplantation of the CCS cells, including pluripotent stem cell (hiPSC)-derived or human embryonic stem cell (hESC)-derived CCS cells.

The invention provides a method for identifying a subject suitable for receiving a lung transplant, the method comprising: subjecting a sample to mass spectrometry analysis (in the negative ion mode or positive ion mode; preferably in the positive ion mode) and generating a mass spectrum output; wherein said sample is an isolated sample obtained from a subject that is a candidate for receiving a lung transplant; detecting one or more peak set in said mass spectrum output; wherein the presence of said one or more peak set indicates that the subject is not a suitable candidate for receiving a lung transplant; or wherein the absence of said one or more peak set indicates that the subject is a suitable candidate for receiving a lung transplant. The invention relies on the detection of peak sets specific to the membrane of pathogens, in particular mycobacteria.

The application discloses a kind of thoracic cardiovascular surgery vessel holders, belong to blood vessel clamping technical field, by support base component, multi-axis support component and clamping component composition, support base component uses double vacuum pump to be matched with double structure adsorption head, can be closely adsorbed in medical plane, provide stable base;Multi-axis support component includes seven-axis linkage structure and self-locking joint, can realize all-around angle and height adjustment, the sixth rotating shaft is telescopic rod, and depth fine adjustment can be completed in cooperation with assembly seat, and automatically lock position after adjustment;Clamping component is clamped by screw rod screw thread transmission and lever structure, and is matched with elastic clamp pad and gyro wheel, and clamping force is accurately controllable, and screw thread self-locking can be durable pressure retention;The device does not need to be continuously hand-held, can avoid blood vessel injury, adapts multiple blood vessel operation scene, effectively improves the safety and operating efficiency of thoracic cardiovascular surgery.

This utility model belongs to the field of medical device technology and discloses a tunneling knife for cardiothoracic surgery. It includes a knife body and blade tips and a handle respectively disposed at both ends of the knife body, with the blade tips being conical or bullet-shaped. This utility model has a simple structure, is easy to operate, can precisely control the size and shape of the incision, and results in a small surgical wound, making it highly practical. This utility model also includes a tunnel tube sleeved on the knife body. The tunnel tube sleeved on the knife body allows the tunnel tube to be inserted into the puncture tunnel during the puncture process. After the puncture is completed, there is no need to insert the tunnel tube separately after the puncture, which greatly improves surgical efficiency.

The invention provides a respiratory function training system and method for a patient in the cardiothoracic surgery department, and the method comprises the steps: matching a similar patient group of a target patient from historical rehabilitation records based on obtained individual attribute data, and extracting the dynamic training data of the similar patient group; determining a tidal volume difference coefficient according to the average tidal volume of the target patient in the current training period and the tidal volume distribution of the similar patient group, and determining an endurance difference coefficient according to the sustainable training duration of the target patient in the current training period and the sustainable training duration of the similar patient group, and carrying out weighted fusion on the tidal volume difference coefficient and the endurance difference coefficient to obtain a training performance difference degree between the target patient and the similar patient group, and carrying out adaptive optimization on a training scheme of the next training period of the target patient according to the training performance difference degree and the pain score of the target patient. According to the scheme, the self-adaptive training scheme of the patient can be constructed based on the historical rehabilitation data.
