Medical multifunctional drainage device

Abstract

The invention relates to the field of medical devices and discloses a medical multifunctional drainage device. The device includes a support assembly, a weighing suspension-support assembly, a drainage adjustment assembly, a controller and a power supply assembly; the weighing suspension-support assembly can support a drainage bag and feed the changing state of the accumulated fluid weight in thedrainage bag back to the controller; the drainage adjustment assembly includes a first tube rolling mechanism and a second tube rolling mechanism whose working states are controlled by the controller,the first tube rolling mechanism and the second tube rolling mechanism jointly act on a drainage tube to achieve and adjust the negative pressure drainage process, and the first tube rolling mechanism can regulate the normal pressure drainage process. The medical multifunctional drainage device adopts intellectualized design and cooperates with an existing conventional drainage component in use to achieve the automatic control of timing drainage, quantitative drainage and constant-speed drainage, the safety and stability of drainage operation are improved, the device has two drainage modes including the normal pressure drainage and the negative pressure drainage, and the needs of most clinical drainage can be met.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 201811135069X 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
