Multipurpose electric clinical drainage device

Abstract

The invention relates to the field of medical instruments, and discloses a multipurpose electric clinical drainage device. The device comprises a support assembly, a weighing type sling assembly supported by the support assembly, a drainage adjusting assembly, a controller and a power supply assembly; wherein the weighing type sling assembly can provide support for a drainage bag and feedback a weight signal to the controller; the controller can regulate and control the working state of the drainage adjusting assembly based on the obtained weight signal, preset drainage modes and drainage parameters, so that the drainage adjusting assembly can extrude a drainage tube in different ways to realize the operation and control of negative pressure drainage and normal pressure drainage; the multipurpose electric clinical drainage device adopts an intelligent design, can realize automatic control of timing drainage, quantitative drainage and constant-speed drainage when being matched with an existing drainage assembly, improves the safety and stability of drainage operation, and has two kinds of drainage modes including normal pressure drainage and negative pressure drainage so as to meetrequirements of most of clinical drainage and have wide clinical application prospects.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018111350558 submitted on September 28, 2018. technical field [0002] The invention relates to the technical field of medical devices, in particular to a multi-purpose electric clinical drainage device which can automatically control various drainage operations clinically. 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 a...

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
