Automatic control device for medical clinical drainage

Abstract

The invention relates to the field of medical instruments, and discloses an automatic control device for medical clinical drainage. The device comprises a weighing type base assembly, a suspension support assembly, a placing seat assembly, a flow rate adjusting mechanism and a negative pressure drainage mechanism, wherein the weighing type base assembly feeds back a weight signal to a controller;a connecting tube for connecting a drainage tube and a drainage bag is arranged in the placing seat assembly; the flow rate adjusting assembly can extrude the connecting tube to different degrees under control of the controller so as to realize the purpose of controlling on-off of the connecting tube and the flow rate of a fluid; and the negative pressure drainage mechanism can force accumulated liquid of the connecting tube to move towards the drainage bag under control of the controller so as to provide negative pressure for drainage. The medical clinical drainage automatic control device isintelligently designed, and can be used to realize automatic control of timing drainage, quantitative drainage and constant-speed drainage when being matched with conventional drainage assemblies, sothat safety and stability of drainage operation are improved. The automatic control device has two drainage modes of normal pressure drainage and negative pressure drainage, and can meet most clinical drainage requirements.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 201811135065.1 submitted on September 28, 2018. technical field [0002] The invention relates to the technical field of medical devices, in particular to a medical clinical drainage automatic control device for effusion drainage. 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 c...

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
