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

Embodiment 1

[0040] see figure 1 , 2 As shown, a medical automatic drainage device disclosed in this embodiment is composed of a bracket assembly, a weighted suspension assembly 3, a drainage adjustment assembly, a controller 12 and a power supply part 18;

[0041] Among them, see figure 1 , 2 As shown, the bracket assembly is composed of a base 1, a column 2 and a mounting plate 14; ; The placement plate 14 is used to provide support and installation space for other components;

[0042] Among them, see figure 2 , 9 , 10, the weight-based suspension assembly 3 is supported by the placement plate 14, with a built-in load cell 17, and a suspension part 16 is provided at the lower end; Provide the only support and make the drainage bag 26 hang below the placement plate 14, which can adjust the height of the drainage bag 26, and the load cell 17 outputs a weight signal that can reflect the changing state of the fluid weight in the drainage bag 26;

[0043] Among them, see image 3 , ...

Embodiment 2

[0080] see Figure 4 , 5 As shown, in the medical automatic drainage device disclosed in the foregoing embodiments, the cross-section of the introduction hole 10 is circular, so as to ensure the integrity of the side wall of the recess 4 to the greatest extent, based on the circular hole adopted by the introduction hole 10 structure, when the drainage tube 25 is introduced into the annular gap, it is necessary to pass the tail end of the drainage tube 25 through the introduction hole 10 from front to back, and the operation is not convenient enough; Plate 14 has the following improvements:

[0081] Such as Figure 14 , 15 As shown, the set plate 14 has a square groove 35 which can fully expose the introduction hole 10 on the front side wall, and a sliding baffle 33 with a moving stroke is defined in the square groove 35; when the sliding baffle 33 is in its stroke At the beginning, it will block the front side of the introduction hole 10 and can compress the drainage tube ...

Embodiment 3

[0084] see figure 2 , 9 , 10, in the medical automatic drainage device disclosed in embodiment 1, the accuracy of the weighing signal output by the load cell 17 is greatly affected by whether the medical automatic drainage device is placed horizontally; Although the difference can be solved by laying objects under the base 1, the operation is cumbersome and time-consuming. For this reason, this embodiment is based on the structure of the medical automatic drainage device disclosed in Embodiment 1. With the following improvements:

[0085] Such as Figure 16 , 17 As shown, the rear side of the placement plate 14 is fixed with a first rotating shaft 38 extending horizontally backward, and a swing seat 39 is fixed by the first rotating shaft 38 so as to be able to swing left and right in a small range; The upper end is connected with the swing seat 39 through the second rotating shaft 37 so that the weight-based suspension assembly 3 can swing back and forth in a small range...

Abstract

The invention relates to the field of medical apparatuses and instruments and discloses a medical automatic drainage device. The medical automatic drainage device is composed of a support assembly, aweighing type hung supporting assembly, a drainage adjusting assembly, a controller and a power portion, wherein the weighing type hung supporting assembly, the drainage adjusting assembly, the controller and the power portion are supported by the support assembly. The weighing type hung supporting assembly can support a drainage bag and feed back a weight signal reflecting a hydrops weight changestate for the controller; the drainage adjusting assembly can produce different modes of extrusion to a drainage tube to adjust a drainage state; the controller can adjust and control the working state of the drainage adjusting assembly based on the obtained weight signal and preset drainage mode and drainage parameters. The medical automatic drainage apparatus adopts intellectualized design, canbe matched with an existing conventional drainage assembly in use to achieve automatic control of timed drainage, quantified drainage and constant-speed drainage, improves the safety and stability ofdrainage operation, provides the two drainage modes of ordinary pressure drainage and negative pressure drainage, can meet most clinic drainage demands and clinically has a wide application prospect.

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...
