Multifunctional drainage control device

Abstract

The invention relates to the field of medical instruments, and discloses a multifunctional drainage control device which is formed by a support assembly and a weight measurement type suspension assembly, a drainage adjustment assembly, a controller and a power supply assembly supported by the support assembly. The weight measurement type suspension assembly can provide support for a drainage bag and feed back a weight signal to the controller. The controller can adjust the working state of the drainage adjustment assembly based on the acquired weight signal and the preset drainage mode and drainage parameters, so that the drainage adjustment assembly conducts different modes of extrusion on a drainage tube to achieve operation and control of negative pressure drainage and normal pressure drainage. The multifunctional drainage control device adopts the intelligent design, can be matched with the existing conventional drainage assemblies in use to achieve automatic control of timing drainage, quantitative drainage and constant speed drainage, and improves the drainage safety and stability. The device has two drainage modes of the normal pressure drainage and the negative pressure drainage, can meet most clinical drainage needs and has broad application prospects in clinical practices.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018111351052 submitted on September 28, 2018. technical field [0002] The invention relates to the technical field of medical devices, in particular to a multifunctional drainage control device capable of automatically controlling various drainage techniques in clinical practice. 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 eff...

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
