Full-automatic medical drainage device

Abstract

The invention relates to the field of medical apparatuses, and discloses a full-automatic medical drainage device. The full-automatic medical drainage device is composed of a support assembly, and a weighing type hanging and supporting assembly, a drainage adjusting assembly, a controller and a power supply assembly which are supported by the support assembly. The weighing type hanging and supporting assembly can provide support for a drainage bag and feed weight signals for reflecting the accumulated liquid weight variation state back to the controller. The drainage adjusting assembly can extrude the drainage pipe in different ways to adjust the drainage state. The controller can control the working state of the drainage adjusting assembly on the basis of the obtained weight signals, thepreset drainage mode and drainage parameters. The full-automatic medical drainage device can automatically control the regular drainage, quantitative drainage and speed-fixed drainage when used in cooperation with an existing conventional drainage assembly by means of the intelligent design, improves the safety and stability of drainage operation, has a normal-pressure drainage mode and a negative-pressure drainage mode, can meet most of the clinical drainage requirements, and has wide application prospects clinically.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and in particular to a fully automatic medical 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 lubricates 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 fluid and ascites. There are many causes of ascites and pleural effusions, which are very common clinical symptoms. Although ascites and pleural effusions are only a symptom, large amounts of ascites and pleural effusions can cause a series of complications The disease is not conducive to the treatment of the cause, and even life-threatening in severe cases. Therefore, for cases with a large amount of abdominal effusion and a ...

AI Technical Summary

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
