Abstract
Description
Technical Field
[0001] This utility model relates to the field of pleural effusion treatment technology, specifically a cardiothoracic surgery pleural effusion drainage device. Background Technology
[0002] The pleural cavity is a potential septum between the lungs and the chest wall. Normally, a thin layer of fluid exists in the lower abdomen, allowing for easier breathing. This fluid is not static; each breath causes some fluid to be filtered out and absorbed, maintaining a balance. When fluid is filtered out too quickly and absorbed too slowly, pleural effusion occurs. Primary diseases of the pleura and pleural membranes can cause pleural effusion, as can some extrapulmonary diseases. When pleural effusion is detected, a catheter is usually inserted for drainage.
[0003] Current pleural effusion drainage devices, after being inserted into the pleural cavity, drain the effusion through drainage. The effusion usually has a high content of protein and cells, and a high density, which can easily block or even solidify at the port of the indwelling drainage tube, causing blockage and affecting the smooth flow of drainage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1-4 A cardiothoracic surgical pleural effusion drainage device includes a main frame 1, an adjustment assembly 2 installed on the inner wall of the main frame 1, a drainage box 101 installed on the side wall of the adjustment assembly 2, the adjustment assembly 2 being used to adjust the height of the drainage box 101, a flexible tube 102 fixedly connected to the top of the drainage box 101, a drainage assembly 3 installed on the side wall of the flexible tube 102, the drainage assembly 3 being used to drain and filter pleural effusion, and further includes:
[0024] The drainage component 3 includes a first connecting tube 301, which is fixedly connected to the end of the hose 102. A second connecting tube 302 is fixedly connected to the end of the first connecting tube 301. A suction cup 303 is snapped into the bottom of the second connecting tube 302. A suction tube 304 is fixedly connected to the end of the suction cup 303. Multiple openings are provided on the side wall of the suction tube 304, and the second connecting tube 302, the suction cup 303, and the suction tube 304 are connected in communication.
[0025] A sliding post 305 is slidably connected to the top of the second connecting tube 302. A cleaning block 306 is fixedly connected to the bottom end of the sliding post 305 located in the inner cavity of the suction cup 303, and the cleaning block 306 can extend into the suction tube 304 and the inner cavity of the second connecting tube 302.
[0026] A filter screen 307 is fixedly connected between the first connecting pipe 301 and the second connecting pipe 302. A drain outlet 308 is provided on the side wall of the second connecting pipe 302, which is located above the first connecting pipe 301.
[0027] It should be noted that: the opening on the side wall of the suction tube 304 allows the pleural effusion of the patient to be sucked into the drainage box 101 through the suction cup 303, the second connecting tube 302, the first connecting tube 301, and the tubing 102. The filter screen 307 installed between the first connecting tube 301 and the second connecting tube 302 can filter impurities to prevent excessive impurities from causing blockage. When the suction tube 304 and the second connecting tube 302 are blocked, the sliding column 305 can be slid. The sliding column 305 will drive the cleaning block 306 to slide and rotate in the inner cavity of the suction tube 304 and the second connecting tube 302. As the cleaning block 306 slides, the impurities in the inner cavity of the second connecting tube 302 slide upward to the top of the inner cavity of the second connecting tube 302, and then the impurities will be discharged through the drain port 308.
[0028] Reference Figure 1-4 The adjustment component 2 includes a threaded post 201, which is rotatably installed in the inner cavity of the main frame 1. The side wall of the threaded post 201 is threadedly connected to the mounting frame 202, and the drainage box 101 is placed in the inner cavity of the mounting frame 202.
[0029] The top of the drainage box 101 is fixedly connected with an outlet pipe 203 and an inlet pipe 204, and the hose 102 is snapped into the inner cavity of the inlet pipe 204;
[0030] It should be noted that: by rotating the threaded column 201, the threaded connection between the threaded column 201 and the mounting frame 202 can be used to make the mounting frame 202 drive the drainage box 101 to slide up and down, thereby adjusting the height of the drainage box 101. The drainage speed can be changed by using the height difference between the drainage box 101 and the suction tube 304. The liquid outlet tube 203 can drain the accumulated liquid in the cavity of the drainage box 101.
[0031] Reference Figure 1-4 The diameter of the suction cup 303 is larger than that of the second connecting tube 302 and the suction tube 304. The cleaning block 306 is made of elastic material, and the bottom of the suction cup 303 is provided with glue.
[0032] The top of the sliding column 305 is rotatably connected to a rotating plate 4, and the top of the second connecting pipe 302 is fixedly connected to a limiting column 401, and the rotating plate 4 can overlap the top of the limiting column 401.
[0033] It should be noted that when the rotating plate 4 overlaps the top of the limiting post 401, the cleaning block 306 can be kept in the inner cavity of the suction cup 303 without obstructing the drainage of accumulated fluid by the suction tube 304 and the second connecting tube 302. The cleaning block 306 is made of elastic material, which allows the cleaning block 306 to be tightly attached to the inner wall of the second connecting tube 302 and the suction tube 304, thereby enhancing the cleaning effect. The adhesive at the bottom of the suction cup 303 can stick the suction cup 303 to the patient's drainage site for easy fixation.
[0034] Operating method: Rotate the threaded column 201. Utilizing the threaded connection between the threaded column 201 and the mounting frame 202, the mounting frame 202 can drive the drainage box 101 to slide up and down, thereby adjusting the height of the drainage box 101. The drainage speed can be changed by utilizing the height difference between the drainage box 101 and the suction tube 304. The pleural effusion of the patient can be sucked into the drainage box 101 through the suction cup 303, the second connecting tube 302, the first connecting tube 301, and the tubing 102 using the opening on the side wall of the suction tube 304.
[0035] The filter 307 installed between the first connecting tube 301 and the second connecting tube 302 can filter impurities and prevent excessive impurities from causing blockage. When the straw 304 and the second connecting tube 302 are blocked, the sliding column 305 can be slid. The sliding column 305 will drive the cleaning block 306 to slide and rotate in the inner cavity of the straw 304 and the second connecting tube 302. As the cleaning block 306 slides, the impurities in the inner cavity of the second connecting tube 302 slide upward to the top of the inner cavity of the second connecting tube 302, and then the impurities will be discharged through the drain port 308.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
