Thoracic cavity drainage automatic control device

Abstract

The invention relates to the field of medical instruments, and discloses a thoracic cavity drainage automatic control device. The device is composed of a weighing type support, a flow rate adjusting mechanism, a controller and a power supply assembly; the weighing type support is provided with a containing groove used for containing and clamping a drainage tube and a weighing sensor used for weighing; the flow rate adjusting mechanism comprises a fixed clamping block and a movable clamping block, and the purposes of controlling on-off of the drainage tube and adjusting the flow rate of fluid can be achieved by extruding the drainage tube in the containing groove; the controller can correspondingly control the flow speed adjusting mechanism based on preset drainage parameters and the changestate of the real-time weight data in the drainage period; and the power supply assembly is used for providing working current for power consumption elements. The thoracic cavity drainage automatic control device adopts an intelligent design, can realize automatic control of timing drainage, quantitative drainage and constant-speed drainage by being matched with an existing conventional drainageassembly for use, improves the safety and stability of drainage operation, saves manpower, guarantees the drainage effect, and is convenient and fast to use.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018111350223 submitted on September 28, 2018. technical field [0002] The invention relates to the technical field of medical instruments, in particular to an automatic control device used in thoracic drainage. 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...

Problems solved by technology

[0004] 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 process is often caused by misunderstanding in the oral communication of the doctor's order or the negligence of the operator. Failure to perform as expected by the doctor may cause discomfort and injury to the patient due to improper drainage, and even endanger 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. Larger size 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.
