Clinical medical drainage device

Abstract

The invention relates to the field of medical instruments, and discloses a clinical medical drainage device. The clinical medical drainage device comprises a weighing type base assembly, a suspensionsupport assembly, a placement seat assembly, a flow speed adjusting mechanism and a negative pressure drainage mechanism. The weighing type base assembly can feed back a weight signal to a controller.A placement groove capable of clamping and fixing the middle lower part of a drainage tube is formed in the placement seat assembly. The flow speed adjusting assembly can extrude the drainage tube todifferent degrees under the control of the controller so as to achieve the purpose of adjusting the flow speed of fluid in the drainage tube. The negative pressure drainage mechanism can gradually drive the drainage tube to output fluid under the control of the controller so as to achieve negative pressure drainage. According to the clinical medical drainage device, intelligent design is adopted,automatic control over timing drainage, quantitative drainage and constant-speed drainage can be achieved when the clinical medical drainage device is used in cooperation with an existing conventional drainage assembly, the safety and stability of drainage operation are improved, the clinical medical drainage device has two drainage modes of normal-pressure drainage and negative-pressure drainage, and most clinical drainage requirements can be met.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018111350308 submitted on September 28, 2018. technical field [0002] The invention relates to the technical field of medical devices, in particular to a clinical medical drainage device which can be used for clinical 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 effusio...

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
