Clinical intelligent thoracic cavity drainage device

Abstract

The invention discloses a clinical intelligent thoracic cavity drainage device. The device is composed of a support assembly and a drainage regulation and control assembly. The support assembly comprises a base, a floating plate, a cross beam and a combined cylinder; a cylinder cover capable of being in butt joint with the combined cylinder is arranged on the lower side of the cross beam; and thesupport assembly provides support for the drainage regulation and control assembly and a drainage bag. The drainage regulation and control assembly is composed of a controller, a weighing sensor usedfor feeding back weight data, an electromagnetic regulating valve used for connecting a drainage tube and the drainage bag, a negative pressure pump used for providing negative pressure for the combined cylinder, and a negative pressure sensor used for feeding back a negative pressure value. The drainage regulation and control assembly can automatically control a drainage process according to preset parameters such as the drainage starting time, the drainage amount, the drainage speed and the negative pressure value. Intelligent design is adopted, and the drainage process can be automaticallycontrolled according to the preset parameters, so that the workload of medical staffs is reduced, and the accuracy, safety and stability of drainage operation are improved. The device can be matched with the drainage bag to achieve negative-pressure drainage, so that the defect of high cost of negative-pressure drainage material consumption in the past is overcome.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018111351122 submitted on September 28, 2018. technical field [0002] The invention relates to a medical product, in particular to a pleural effusion drainage device commonly used in clinical medicine. Background technique [0003] Normal people have 3ml~15ml of fluid in the pleural cavity, which acts as a lubricant during respiratory movement. These fluids are continuously formed and absorbed to maintain a dynamic balance. If this balance is destroyed by disease, the fluid in the pleural cavity will form too quickly. Or if the absorption is too slow, pleural effusion will form, which is also called pleural effusion clinically. 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 c...

Problems solved by technology

During the drainage of a large amount of pleural effusion, there are often specific requirements for clinical parameters such as daily drainage times, each drainage volume, and drainage speed according to the condition of the case. In actual clinical operations, the clinical parameters during the drainage process are usually It is realized by the subjective control of the medical staff or the patient's family members. The current artificial control method has certain disadvantages. On the one hand, the drainage is often caused by misunderstanding in the oral communication of the doctor's order or the negligence of the operator. The process could not be carried out as expected by the doctor, causing discomfort and injury to the patient due to improper drainage, and even endangering the life of the patient. On the other hand, the real-time drainage volume and drainage speed during the drainage process are usually judged by human observation. The large error also makes it difficult to guarantee the drainage effect. At the same time, the current control method will obviously increase the burden on the medical staff and the patient's family members.

[0004] Drainage bags are commonly used medical supplies. They are simple in structure, low in cost, easy to use, and are extremely suitable for one-time use. It can only be applied to conventional pleural effusion drainage operations under normal pressure, but not to negative pressure drainage. For example, when performing negative pressure drainage, it is usually necessary to use a water-sealed bottle that is more expensive than the drainage bag, which brings a certain economic burden to the patient
