Clinical drainage control device

Abstract

The invention relates to the field of medical instruments, and discloses a clinical drainage control device. The device comprises a weighing base assembly, a suspension assembly, a drainage adjustmentassembly, a controller and a power source assembly; during the drainage process, the suspension assembly can provide support for a drainage bag, the weighing base assembly can feed back a weight signal reflecting the change of accumulated liquid in the drainage bag to the controller, the drainage adjustment assembly includes a first rolling mechanism and a second rolling mechanism of which working states are regulated by the controller, by means of the first rolling mechanism and the second rolling mechanism, the negative pressure drainage process can be achieved and regulated, and the firstrolling mechanism can be used for regulating the normal pressure drainage process. The clinical drainage control device adopts an intelligent design, can cooperate with an existing conventional drainage assembly to achieve automatic control of timing drainage, quantitative drainage and constant velocity drainage, improves the safety and stability of the drainage operation, has two drainage modes of the normal pressure drainage and the negative pressure drainage, and can meet most of clinical drainage needs.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018111350948 submitted on September 28, 2018. technical field [0002] The invention relates to the technical field of medical devices, in particular to an intelligent control device for clinical drainage assistance. Background technique [0003] Under normal conditions, there is a small amount of fluid in the thoracic cavity and abdominal cavity of the human body, which can lubricate the organs in the cavity. If the amount of fluid in the cavity increases beyond the normal physiological range under pathological conditions, it will become a disease, such as pleural effusion and ascites. There are many causes of peritoneal effusion and pleural effusion, which are very common clinical diseases. Although peritoneal effusion and pleural effusion are only one symptom, a large amount of peritoneal effusion and large amount of peritoneal effusion will cause a series...

Problems solved by technology

[0004] In the clinical operation of drainage of a large amount of 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. The parameters are usually controlled subjectively by the medical staff or the patient's family members. The current artificial control method has certain disadvantages. As a result, the drainage process cannot be carried out in the way the doctor expected, and the improper drainage will cause discomfort and injury to the patient, and even endanger the patient's life. On the other hand, the real-time drainage volume and drainage speed during the drainage process are usually determined by human observation. Judgment, the error is large, and it is 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.

[0005] The drainage bag is a relatively cheap medical product, and it is the best choice as the terminal container in clinical effusion drainage, but it can only be applied to conventional pleural effusion drainage operations under normal pressure, and cannot be applied to negative pressure drainage. Negative pressure drainage usually requires the use of water-sealed bottles that are more expensive than drainage bags, which brings a certain economic burden to patients
