Medical automatic drainage device

Abstract

The invention relates to the field of medical equipment, and discloses a medical automatic drainage device, which is composed of a bracket assembly, a weight-based suspension assembly supported by the bracket assembly, a drainage adjustment assembly, a controller, and a power supply; the weight-based suspension assembly It can provide support for the drainage bag and feed back to the controller a weight signal that reflects the changing state of the weight of the effusion; the drainage adjustment component can squeeze the drainage tube in different ways to adjust the drainage state; the controller can be based on the obtained weight signal and preset The drainage mode and drainage parameters are used to regulate the working status of the drainage adjustment components; the medical automatic drainage device adopts intelligent design, and can be used in conjunction with the existing conventional drainage components to realize automatic control of timing drainage, quantitative drainage and constant speed drainage. The safety and stability of the drainage operation are improved, and it has two drainage modes of normal pressure drainage and negative pressure drainage, which can meet most clinical drainage needs, and has broad application prospects in clinical practice.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical automatic drainage device capable of automatically controlling the drainage process. 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, fo...

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
