Description

Technical Field

[0001] The utility model relates to the technical field of extraction of cardiothoracic tissue fluid in the intensive care unit (ICU) of critical care medicine, and particularly relates to a device for extracting cardiothoracic tissue fluid. Background Art

[0002] In the ICU of critical care medicine, a device for extracting cardiothoracic tissue fluid is a key medical device, which is widely used in the management and treatment of various critically ill patients. In the ICU, patients may have pleural effusion due to reasons such as heart failure, pneumonia, and renal failure. Through the device for extracting cardiothoracic tissue fluid, excess fluid can be effectively removed, the dyspnea of the patient can be relieved, and the oxygenation status can be improved.

[0003] After retrieval, a novel nursing device for cardiothoracic surgery with the publication number CN219630262U, the utility model relates to the technical field of medical devices. The novel nursing device for cardiothoracic surgery includes a liquid storage bottle. One side of the top surface of the liquid storage bottle is provided with a liquid extraction pump, and the input end of the liquid extraction pump is connected with a backflow preventer through a liquid guide pipe. The backflow preventer is used to prevent the backflow of tissue fluid when extracting cardiothoracic tissue fluid; the input end of the backflow preventer is plugged with a drainage pipe, and the drainage pipe is used to be plugged at a designated position in the chest to achieve the derivation of tissue fluid; the input end of the liquid extraction pump is connected with a liquid discharge pipe, and the bottom end of the liquid discharge pipe penetrates through the top surface of the liquid storage bottle. The utility model can not only enable doctors in cardiothoracic surgery to drain gas and liquid in the patient's chest cavity, but also prevent the backflow of tissue fluid when extracting cardiothoracic tissue fluid, thus not affecting the surgical efficiency and not increasing the pain of the patient.

[0004] Based on the above patent, the drainage pipe, the backflow preventer, the liquid guide pipe and the liquid extraction pump are connected in series in sequence, so as to form a pipeline. Then the doctor inserts the drainage pipe into the designated position of the patient, and then the front end of the drainage pipe can be communicated with the gas and liquid in the patient's chest cavity. Then the doctor turns on the liquid extraction pump through the speed adjustment knob to operate, so that the liquid extraction pump can extract the gas and liquid in the patient's chest cavity through the drainage pipe. When the extracted gas and liquid in the chest cavity flow through the backflow preventer, at this time, the plug in the backflow preventer moves towards the sealing plate side under the pumping of the liquid extraction pump, so that the plug is far away from the insertion position of the limiting pipe, and then the extracted gas and liquid can flow into the limiting pipe conveniently, and then flow to the liquid guide pipe through the connecting pipe, then reach the liquid extraction pump, and finally be conveyed to the liquid storage bottle through the liquid discharge pipe to complete the purpose of draining the gas and liquid in the patient's chest cavity. However, when using the extraction device in this patent to extract effusion, the drainage pipe is inconvenient to replace after long-term use, and using the same drainage pipe for a long time is likely to breed bacteria and other pathogenic microorganisms, increasing the risk of patient infection. Infection may lead to serious complications such as sepsis or local infection, affecting the treatment effect of the device. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Referring to Figure 1 and Figure 2 , an embodiment provided by the present invention: A chest and heart tissue fluid extraction device includes a liquid storage bottle 1. A liquid extraction pump 2 is installed at the rear side of the top end of the liquid storage bottle 1. A mounting pipe 3 is fixedly connected to the front side of the top end of the liquid storage bottle 1 and penetrates through it. A liquid guide pipe 4 is fixedly connected to the top end of the mounting pipe 3. A through window 5 is fixedly connected to the front end of the liquid storage bottle 1. The other end of the liquid guide pipe 4 is fixedly connected to a limiting plate 6. A fixed pipe 7 is connected to the inner wall of the limiting plate 6 through a flow blocking component. An installation ring 8 is fixedly connected to the top end of the limiting plate 6. An adjusting ring 10 is threadedly connected to the top end of the installation ring 8. A drainage pipe 9 is connected to the inner wall of the adjusting ring 10 through a replacement component. When extracting the accumulated fluid, the liquid extraction pump 2 generates negative pressure, enabling the liquid storage bottle 1 to extract and squeeze through the liquid guide pipe 4 and the drainage pipe 9. The material of the through window 5 is transparent and has a scale groove, allowing the capacity of the extracted accumulated fluid to be observed. The bottom end of the fixed pipe 7 is fixedly connected to the outer wall of the top end of the liquid guide pipe 4, and the outer wall of the bottom end of the drainage pipe 9 fits with the inner wall of the top end of the fixed pipe 7.

[0028] Specifically:

[0029] Referring to Figure 3 and Figure 4 , a transfer ring 11 is rotatably connected to the bottom end of the adjusting ring 10. Four sides of the inner wall of the transfer ring 11 are rotatably connected to first connecting plates 12. The bottom sides of the opposite ends of the first connecting plates 12 are rotatably connected to second connecting plates 13. The opposite ends of the first connecting plates 12 are rotatably connected to pressing plates 14. An installation groove 15 is formed on the outer wall of the bottom end of the drainage pipe 9. When the drainage pipe 9 needs to be replaced, rotate the adjusting ring 10 to make the transfer ring 11 drive the first connecting plates 12 to move, so that the first connecting plates 12 drive the pressing plates 14 to break away from the installation groove 15 through the second connecting plates 13, enabling the drainage pipe 9 to be detached, facilitating the replacement of the drainage pipe 9. The outer wall of the transfer ring 11 is slidably connected to the inner wall of the installation ring 8. The opposite ends of the second connecting plates 13 are respectively rotatably connected to the four sides of the inner wall of the installation ring 8. The opposite ends of the installation groove 15 are detachably connected to the outer wall of the installation groove 15. When the adjusting ring 10 is rotated in the reverse direction, the adjusting ring 10 drives the first connecting plates 12 through the transfer ring 11 to fix the pressing plates 14 at the installation groove 15, thus facilitating the fixation of the drainage pipe 9 and facilitating the replacement and use of the drainage pipe 9.

[0030] Specifically:

[0031] Referring to Figure 5and Figure 6 A connecting frame 16 is fixedly connected to the inner wall of the fixed tube 7. Fixing plates 17 are fixedly connected to the left and right sides of the inner wall of the connecting frame 16. Closing plates 19 are connected to the top sides of the opposite ends of the fixing plates 17 through return springs 18. After negative pressure is generated in the fixed tube 7, the negative pressure adsorbs the closing plates 19 to open them, allowing the accumulated liquid to flow out. The bottom ends of the return springs 18 are fixedly connected to the top sides of the opposite ends of the fixing plates 17 respectively, and the top ends of the return springs 18 are fixedly connected to the bottom sides of the opposite ends of the closing plates 19 respectively. The opposite ends of the closing plates 19 are rotatably connected to the inner walls of the left and right sides of the top of the connecting frame 16 and fit together. When the liquid extraction pump 2 stops starting, the negative pressure stops, and the elastic force of the return springs 18 causes the closing plates 19 to fit and close again at the connecting frame 16, thereby preventing the accumulated liquid from flowing back.

[0032] Working principle: When extracting the accumulated liquid, the liquid extraction pump 2 generates negative pressure, enabling the liquid storage bottle 1 to extract and squeeze the liquid guide tube 4 through the drainage tube 9. The material of the through window 5 is transparent and has scale grooves, allowing the volume of the extracted accumulated liquid to be observed. When the drainage tube 9 needs to be replaced, rotate the adjustment ring 10 to drive the adapter ring 11 to move the first connecting plate 12, so that the first connecting plate 12 drives the extrusion plate 14 to fall off from the installation groove 15 through the second connecting plate 13, enabling the drainage tube 9 to be detached, facilitating the replacement of the drainage tube 9. When the adjustment ring 10 is rotated in the reverse direction, the adjustment ring 10 drives the first connecting plate 12 through the adapter ring 11 to fix the extrusion plate 14 at the installation groove 15, facilitating the fixation of the drainage tube 9 and the replacement and use of the drainage tube 9. This helps prevent catheter blockage caused by the accumulation of blood, tissue fluid, or sediment, ensures the smooth discharge of the liquid, prevents the growth of bacteria and other pathogenic microorganisms in the tube, thereby reducing the risk of infection. After negative pressure is generated in the fixed tube 7, the negative pressure adsorbs the closing plates 19 to open them, allowing the accumulated liquid to flow out. When the liquid extraction pump 2 stops starting, the negative pressure stops, and the elastic force of the return springs 18 causes the closing plates 19 to fit and close again at the connecting frame 16, thereby preventing the accumulated liquid from flowing back. Preventing the accumulated liquid from flowing back can prevent the discharged liquid from re-entering the body, reducing the chance of bacteria or other pathogens entering the body through the flowing-back liquid, thereby reducing the risk of infection, protecting the tissue, and promoting healing and recovery.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
