Medical multifunctional drainage device

Abstract

The invention relates to the field of medical instruments, and discloses a medical multifunctional drainage device. The medical multifunctional drainage device comprises a support assembly, a weightedsuspension assembly, a drainage adjustment assembly, a controller and a power supply assembly; the weighted suspension assembly can support a drainage bag and feeds back a change state of the weightof an accumulated liquid in the drainage bag to the controller; the drainage adjustment assembly comprises a first tube rolling mechanism and a second tube rolling mechanism of which the working states are controlled by the controller, a negative pressure drainage process can be achieved and adjusted through the cooperative action of the first tube rolling mechanism and the second tube rolling mechanism on the drainage tube, and the first tube rolling mechanism can adjust a normal pressure drainage process. The medical multifunctional drainage device has the advantages that intelligent designis adopted, the automatic control of timing drainage, quantitative drainage and constant-velocity drainage can be achieved through the cooperative use of the medical multifunctional drainage device and an existing common drainage assembly, the safety and stability of the drainage operation are improved, and the two drainage modes of normal drainage and negative drainage can meet the requirements of most clinical drainage.

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 a multifunctional drainage 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 se...

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
