Drainage chest tube with potential safety hazard early warning mechanism

Abstract

The invention provides a drainage chest tube with a potential safety hazard early warning mechanism. The drainage chest tube comprises a drainage tube body, a displayer and an alarm, a medical one-way valve is arranged in the middle of the drainage tube body, a flow sensor is installed on one side of the medical one-way valve, when the drainage amount changes abnormally, medical staff are reminded to pay attention in time, and the safety of a patient is guaranteed. The upper side of the drainage tube body is provided with a first medicine guide cavity, the lower side of the drainage tube body is provided with a second medicine guide cavity, one end of the first medicine guide cavity and one end of the second medicine guide cavity are connected with medicine inlets, and the other end of the first medicine guide cavity and the other end of the second medicine guide cavity are connected with medicine guide openings. According to the drainage chest tube with the potential safety hazard early warning mechanism, a pressure sensor is arranged, the pressure between the connecting sleeve and the drainage opening can be monitored in real time, when the connecting sleeve falls off, the data value received by the pressure sensor changes, medical workers are reminded of the situation that the tube falls off possibly, and checking is conducted in time.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a drainage chest tube with an early warning mechanism for potential safety hazards. Background technique [0002] Diseases in the field of thoracic surgery often involve life-related organs, such as the heart and lungs, and the treatment process often affects the stability of the function of these organs, thus threatening life. After thoracic surgery, it is necessary to use closed chest drainage to collect the fluid in the patient's chest cavity. Closed chest drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water-sealed bottle lower than its position. In order to expel gas or collect fluid in the pleural cavity, so that the lung tissue can reopen and restore function, as a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy. It plays an important role in...

Problems solved by technology

[0005] The purpose of the present invention is to provide a drainage chest tube with an early warning mechanism for potential safety hazards, so as to solve the problem that the pipe connection method of the existing drainage chest tube proposed in the above-mentioned background technology is simple and not firm, and often occurs that the pipe is not firmly fixed or even falls off. Nursing and medical adverse events such as tubes seriously affect the safety of patients. At present, the existing technology cannot identify the occurrence of tube detachment events early. Often, patients have already experienced tube detachment events, resulting in serious adverse accidents such as open tubes and open thorax; after thoracic surgery Sudden increase in pleural fluid often occurs, and the maximum drainage volume of the human body is more than 200ml per hour or more than 1000ml within 12 hours. Too fast drainage will lead to rapid swing shift of the mediastinum or the occurrence of re-expansion pulmonary edema, which requires emergency medical treatment, but At present, the function of the chest tube is single, and the sudden increase of pleural fluid cannot be clamped in time. Manual intervention is required, but the best closing time is often missed, and there is a huge safety hazard, which cannot meet people's needs.
