Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fluid drainage, and specifically relates to a cardiovascular surgery fluid drainage device and a drainage method. Background Art
[0002] Pleural effusion is formed by an increase in the production of fluid in the pleural cavity or a decrease in the absorption and return flow, which will exert pressure on the lung tissue and cause symptoms of dyspnea. Cardiovascular surgeons usually perform closed thoracic drainage to suck the fluid in the chest cavity out of the body, so that the lung tissue can reopen and restore its function.
[0003] Based on the above, the inventor of the present invention found that the existing thoracic effusion suction devices for cardiovascular surgery have the following deficiencies:
[0004] 1. Most of the existing drainage devices are directly placed / hung outside the hospital bed, with poor stability and prone to falling off during the drainage process, posing a safety hazard.
[0005] 2. The capacity of the drainage bottle is limited. When the drainage bottle is full, the drainage bottle needs to be replaced. If the drainage tube and negative pressure tube on the drainage bottle are unplugged and plugged, it will affect the sealing performance of the connection nodes between the negative pressure tube and the drainage tube and the drainage bottle, affecting the subsequent drainage effect.
[0006] 3. If a drainage port is set on the drainage bottle, the drainage will destroy the negative pressure state in the drainage bottle, and the negative pressure device needs to be restarted to keep the drainage bottle in a negative pressure state, and the operation is not convenient. Therefore, there is an urgent need to provide a cardiovascular surgery fluid drainage device and a drainage method. Summary of the Invention
[0007] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, the abstract of the specification and the title of the invention of this application to avoid obscuring the purpose of this part, the abstract of the specification and the title of the invention, and such simplifications or omissions cannot be used to limit the scope of the present invention.
[0008] Therefore, the purpose of the present invention is to provide a cardiovascular surgery fluid drainage device and a drainage method. The motor drives the double-headed lead screw to rotate in the connection groove, so that the two groups of limit clamping plates move relatively along the double-headed lead screw. Through the cooperation of the two groups of limit clamping plates, the overall position of the device is fixed to ensure the stable effect of the device during use. The set drainer outputs the accumulated fluid to the drainage bottle through the drainage tube and the drainage pipe. During the drainage process, the pressure sensor a is used to monitor the pressure of the accumulated fluid in the discharge pipe in real time, and the flow sensor a is used to monitor the flow rate of the accumulated fluid in the drainage tube. When the pressure of the accumulated fluid in the discharge pipe is too high, the drainer changes the drainage power to prevent the situation of blockage caused by too fast input of the accumulated fluid.
[0009] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0040] To make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation manners of the present invention in detail in conjunction with the accompanying drawings.
[0041] The present invention provides a cardiovascular surgery effusion drainage device and a drainage method. By xxxx, please refer to Figures 1-6 , including a connecting frame 100, a clamping assembly 200, a drainage assembly 300 and a shunt assembly 400;
[0042] Please continue to refer to Figure 1 ,Figure 2 , Figure 3 and Figure 5 , as the connecting frame 100 for connecting the base frame, a connecting groove 110 is provided inside the connecting frame 100, and a sliding groove 111 communicating with the connecting groove 110 is provided on the outside of the connecting frame 100. An elastic clip 120 is connected to the outside of the connecting frame 100. A plurality of anti-slip bumps (not marked in the figure) are integrally formed inside the elastic clip 120. The elastic clip 120 is used to clamp the drainage bottle 320;
[0043] Please continue to refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the clamping assembly 200 is connected to the connecting frame 100, including a motor 210 threadedly connected to the outside of the connecting frame 100. The output end of the motor 210 is connected to a double-headed lead screw 211. Two sets of threaded sleeves 220 are symmetrically screwed on the double-headed lead screw 211 (since the rotation direction of the threaded sleeve is restricted by the sliding groove and the sliding seat, when the double-headed lead screw rotates, the two limit clamping plates move relative to each other and perform a threaded feeding action). A sliding seat 221 that is slidably matched with the sliding groove 111 is integrally formed on the outside of the threaded sleeve 220, and a limit clamping plate 230 is connected to the outside of the sliding seat 221;
[0044] Action:
[0045] The motor 210 works, driving the double-headed lead screw 211 to rotate inside the connecting groove 110, so that the two limit clamping plates 230 move relative to each other on the double-headed lead screw 211. Through the cooperation of the two limit clamping plates 230, the overall position of the device is fixed to ensure the stable effect of the device during use;
[0046] Please continue to refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the drainage assembly 300 is connected to the connecting frame 100 to drain the accumulated fluid;
[0047] The drainage assembly 300 includes a drainer 310 threadedly connected to the bottom of the connecting frame 100 through a connecting bolt. The input end of the drainer 310 is connected to a drain pipe 311, the output end of the drainer 310 is connected to a drain pipe 312, and the other end of the drain pipe 312 is connected to a drainage bottle 320. The drainage bottle 320 is placed inside the elastic clip 120;
[0048] A flow sensor 311a is connected to the drain pipe 311, and a pressure sensor 312a is connected to the drain pipe 312;
[0049] The drainer 310 works to output the accumulated fluid into the drainage bottle 320 through the drainage tube 311 and the discharge tube 312. During the drainage process, the pressure sensor 312a is used to monitor the pressure of the accumulated fluid in the discharge tube in real time, and the flow sensor 311a is used to monitor the flow rate of the accumulated fluid in the drainage tube. When the pressure of the accumulated fluid in the discharge tube 312 is too high, the drainer 310 changes the drainage power to prevent the situation of blockage caused by too fast input of the accumulated fluid.
[0050] Please continue to refer to Figure 1 、 Figure 4 and Figure 5 ,the shunt assembly 400 is connected to the connecting frame 100 and is communicated with the drainage assembly 300 to shunt the drainage assembly 300;
[0051] The shunt assembly 400 includes a liquid outlet pipe 410 communicated with the drainage bottle 320. A control valve 411 is connected to the liquid outlet pipe 410. The other end of the liquid outlet pipe 410 is communicated with a drainage bag 420. The drainage bag 420 is connected to the end of the liquid outlet pipe 410 through a threaded connection head 421;
[0052] When the accumulated fluid in the drainage bottle 320 reaches a certain volume, the control valve 411 is used to control the opening of the liquid outlet pipe 410. At this time, the accumulated fluid is transported into the drainage bag 420 through the liquid outlet pipe 410. After the accumulated fluid in the drainage bag 420 is full, the control valve 411 is closed, the drainage bag is unscrewed, and a new drainage bag is replaced, which can avoid directly discharging the liquid and destroying the negative pressure state in the drainage bottle 320;
[0053] Please refer to Figure 6 ,a drainage method applied to any cardiovascular surgery fluid drainage device, characterized by including the following steps:
[0054] S1. Drive the double-headed lead screw to rotate through the motor, so that the two groups of limit clamping plates move relatively. Through the cooperation of the two groups of limit clamping plates, the overall position of the device is fixed;
[0055] S2. After being fixed in step S1, control the drainer to work through the control panel. The drainer outputs the accumulated fluid into the drainage bottle through the drainage tube and the discharge tube;
[0056] S3. During the drainage process in step S2, the pressure sensor is used to monitor the pressure of the accumulated fluid in the discharge tube in real time, and then the flow sensor is used to monitor the flow rate of the accumulated fluid in the drainage tube. When the pressure of the accumulated fluid in the discharge tube is too high, the drainer changes the drainage power;
[0057] S4. During the drainage process through step S3, when the accumulated fluid in the drainage bottle reaches a certain volume, control the liquid outlet pipe to open through the control valve. At this time, the accumulated fluid is transported into the drainage bag through the liquid outlet pipe;
[0058] S5. After the accumulated fluid in the drainage bag is full, the control valve is closed, the drainage bag is unscrewed, and a new drainage bag is replaced.
[0059] Working principle: When the invention is in use, the motor 210 drives the double-headed lead screw 211 to rotate in the connection groove 110, so that the two groups of limit clamping plates 230 move relatively along the double-headed lead screw 211. Through the cooperation of the two groups of limit clamping plates 230, the overall position of the equipment is fixed to ensure the stable effect during the use of the equipment. Then, the drainage device 310 outputs the accumulated liquid to the drainage bottle 320 through the drainage pipe 311 and the drainage pipe 312. During the drainage process, the pressure sensor 312a monitors the pressure of the accumulated liquid in the discharge pipe in real time, and the flow sensor 311a monitors the flow rate of the accumulated liquid in the drainage pipe. When the pressure of the accumulated liquid in the discharge pipe 312 is too high, the drainage device 310 changes the drainage power to prevent the situation of blockage caused by too fast input of the accumulated liquid;
[0060] Meanwhile, when the accumulated liquid in the drainage bottle 320 reaches a certain volume, the control valve 411 is used to control the opening of the liquid outlet pipe 410. At this time, the accumulated liquid is transported to the drainage bag 420 through the liquid outlet pipe 410. After the accumulated liquid in the drainage bag 420 is full, the control valve 411 is closed, the drainage bag is unscrewed, and a new drainage bag is replaced, which can avoid directly discharging the liquid and destroying the negative pressure state in the drainage bottle 320.
[0061] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
