Intelligent control device for clinical drainage assistance

Abstract

The invention relates to the field of medical devices, and discloses an intelligent control device for clinical drainage assistance, which comprises a weight base assembly, a suspension assembly, a drainage adjustment assembly, a controller and a power supply assembly; in the course of drainage, the suspension assembly can provide support for a drainage bag, the weight base assembly can feedback the weight signal that reflects the change of the liquid in the drainage bag to the controller, and the drainage adjustment assembly includes two rolled pipe mechanisms, the working states of which areregulated by the controller. Through a roll, the on and off of the drainage pipe can be controlled and the flow velocity of the efflux can be adjusted. Through the matching of two rolls, the necessary negative pressure for the negative pressure drainage can be provided. The intelligent control device is intelligently designed, and can achieve automatic control of timing drainage, quantitative drainage and constant speed drainage by combining a prior drainage assembly, and the safety and stability of drainage operation are improved. The device has two drainage modes: normal pressure drainage and negative pressure drainage, which can meet most clinical drainage requirements.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent control device for clinical drainage assistance. Background technique [0002] 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 series of complications. Symptoms are not conducive to the treatment of the cause, and even life-threatening in severe cases. Therefore, for cases with a large amount of ...

Problems solved by technology

[0003] 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.

[0004] 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
