Description

Technical Field

[0001] The utility model belongs to the technical field of medical drainage devices, and particularly relates to an efficient drainage device for malignant tumor pleural effusion. Background Art

[0002] In the advanced stage of lung cancer, pleural effusion will occur. As a device for draining gas or liquid in the chest cavity, thoracic drainage can reduce the compression of the lungs by the effusion or gas by draining the chest cavity, enabling the lung tissue to reopen and recover its function. At the same time, it is also more conducive to the healing of the patient's wound. The existing thoracic drainage device consists of a drainage bottle and a drainage tube. The process of draining pleural effusion requires professional medical staff for care. Since it is impossible to monitor at all times, abnormal drainage volume cannot be effectively monitored. When the drainage tube is bent, the drainage volume is too large or too small, or after the pleural effusion in the chest cavity is drained, it cannot be effectively monitored, which is extremely likely to cause secondary damage to the patient.

[0003] Therefore, this application proposes an efficient drainage device for malignant tumor pleural effusion to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer and more explicit, the present utility model will be described below through specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and do not limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present utility model.

[0020] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] Example 1, in combination with Figures 1 - 3 To illustrate this embodiment, a highly efficient pleural effusion drainage device for malignant tumors in this embodiment includes a high-precision flow meter 4, an electric control valve 5, a drainage tube 6, a drainage bottle fixing bracket 7 and a drainage bottle 8. One end of the drainage tube 6 is inserted into the chest cavity 3, and the other end of the drainage tube 6 is arranged in the drainage bottle 8. A high-precision flow meter 4 and an electric control valve 5 are installed on the drainage tube 6. The high-precision flow meter 4 is arranged at the distal end of the drainage bottle 8, and the electric control valve 5 is arranged at the proximal end of the drainage bottle 8. The drainage bottle 8 is installed on the drainage bottle fixing bracket 7.

[0022] The high-precision flow meter 4 and the electric control valve 5 are also connected to the controller 1. The high-precision flow meter 4 is used to monitor the flow rate of the medium in the drainage tube 6. The electric control valve 5 appropriately adjusts the flow rate of the medium in the drainage tube 6 according to the flow rate displayed on the high-precision flow meter 4 to make it drain within a suitable range. The high-precision flow meter 4 has a 485 communication function and can transmit the detection signal to the controller. Medical staff can set the drainage flow according to the patient's own situation, and set the upper limit value, lower limit value and total drainage volume on the high-precision flow meter 4. When the drainage volume is higher than the set drainage flow, the controller 1 issues a control signal to control the valve opening of the electric control valve 5 to close slightly, so that the flow rate in the drainage tube 6 decreases. When the drainage volume is lower than the set drainage flow, the controller 1 issues a control signal, and the valve opening of the electric control valve 5 automatically opens wide, so that the drainage volume increases. When the drainage volume is higher than the set upper limit value, lower limit value or reaches the total drainage volume, the controller issues a control signal, and the sound and light alarm 2 automatically alarms to notify the medical staff to check in time and reduce the potential medical safety hazards.

[0023] Example 2, in combination with Figures 1 - 3For this embodiment, an efficient drainage device for malignant tumor pleural effusion is provided. According to the different sizes of the drainage bottle 6, an adjustable drainage bottle fixing frame 7 is provided. A fixing frame base 11 is connected to the drainage bottle fixing frame 7. The drainage bottle 6 is placed on the fixing frame base 11. A movable baffle 10 is slidably arranged on the fixing frame base 11. The inner wall of the movable baffle 10 is fitted with the drainage bottle 6, and then the movable baffle 10 is locked on the fixing frame base 11 through a fixing bolt 12 to complete the effective fixing of the drainage bottle 6;

[0024] The bottom of the drainage bottle fixing frame 7 is connected to a servo electric cylinder 9. The telescopic end of the servo electric cylinder 9 is connected to the bottom of the drainage bottle fixing frame 7. In the telescopic state of the servo electric cylinder 9, the up and down position of the drainage bottle 8 is adjusted to ensure that the drainage bottle 8 is at the optimal drainage height. The servo electric cylinder 9 is also installed on a movable seat 13. Four lockable universal wheels are installed at the bottom of the movable seat 13. The movable seat 13 drives the drainage bottle 8 to move its position to avoid the bending of the drainage tube 6, improve the drainage effect and play a certain protective role for the patient.
