Clinical intelligent thoracic cavity drainage device

Abstract

The invention relates to the technical field of medical instruments, and discloses a clinical intelligent thoracic cavity drainage device. A drainage bottle is provided with a negative pressure apparatus, a liquid inlet end, a liquid level sensor used for sensing the amount of hydrops in the drainage bottle, a camera used for shooting the internal state of the drainage bottle, a controller and a storage battery, and the liquid inlet end is provided with a flow speed control mechanism; the controller can calculate the hydrops increment in the drainage bottle according to signals fed back by theliquid level sensor and can regulate and control the working states of the negative pressure apparatus and the flow speed control mechanism on the basis of the hydrops increment and preset drainage amount and drainage time, and timed drainage and quantitative drainage are achieved. The clinical intelligent thoracic cavity drainage device adopts an intelligent design, can automatically control thedrainage state, can realize timed and quantitative drainage, reduces manual operation links, can avoid adverse effects caused by improper manual operation, avoids the defect of hydrops overflow in the drainage bottle, and is particularly suitable for clinical drainage of a large amount of hydrops in the thoracic cavity.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018101087655 submitted on February 5, 2018. technical field [0002] The invention relates to a medical device, in particular to a device used in clinical pleural cavity effusion drainage operation. Background technique [0003] Pleural effusion is a relatively common clinical disease. Various lung diseases such as inflammation, malignant tumors, tuberculosis, fungi, etc. can cause pleural effusion, while extrapulmonary diseases such as heart failure, liver cirrhosis, pericardial effusion, abdominal cavity Malignant tumors, pancreatitis, nephrotic syndrome, malnutrition, chest trauma, etc. are also common causes of pleural effusion. When the amount of pleural effusion is large, it will oppress the lungs and heart, and the patient will feel shortness of breath, chest tightness, and hypoxia. Hyperemia and even respiratory failure, therefore, adequate drainage o...

AI Technical Summary

Problems solved by technology

[0004] Most of the current thoracic drainage is accomplished by means of drainage devices composed of drainage tubes, drainage bottles, and negative pressure bottles. Although this type of drainage device is simple in structure, its function is relatively single and its intelligence is low, so that the drainage process requires manual labor. Observation and control, manual labor intensity is high and mistakes are prone to occur, which will affect the drainage effect and bring great inconvenience to the operation
