Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, in particular to a drainage fluid anti-fouling extractor for nursing tumor patients. Background Art

[0002] Tumor patients often have fluid accumulation in the chest or abdominal cavity, which may cause discomfort such as difficulty breathing and abdominal distension. These symptoms can be quickly relieved by extracting the fluid. In addition, cytological examination of the fluid can provide doctors with important information about the patient's condition, thereby formulating a more accurate treatment plan.

[0003] The patent with the announcement number CN215386310U discloses a fluid extractor for kidney disease and tumor department, including a pumping tube and a piston rod, the piston rod is movably connected to the inside of the pumping tube, the bottom end of the piston rod is fixedly connected to a piston, the lower end of the pumping tube is provided with a pumping cavity, the left and right sides of the lower end of the pumping tube are connected with pumping tubes, one side of the pumping tube is fixedly connected to a drainage tube, the outer end of the drainage tube is interspersed with a barrel cover, the lower end of the barrel cover is fixedly connected to a drainage barrel, and one side of the outer end of the drainage barrel is provided with a liquid level observation window. The utility model proposes a fluid extractor for kidney disease and tumor department, which solves the problem that a syringe is usually used to extract the fluid, but the capacity of the syringe is limited, and the syringe needs to be disconnected from the rubber tube continuously during the extraction process and the fluid is discharged and then connected again until the fluid is completely discharged, which is inconvenient for continuous extraction, and the process is prone to increase the risk of infection for patients, and solves the problem of inconvenience for pathological sampling, and is highly practical.

[0020] 1. The drainage fluid anti-fouling extractor for tumor patient care described in the present invention utilizes an anti-blocking viscous effluent crushing mechanism.

In the subsequent cytological examination, the cell type can be accurately counted and identified, reducing the difficulty of cytological examination. In addition, when the dredging rod is dredging the through-hole, it is within the enclosure range of the concave plate, so, The dredging rod will only push down the thick liquid attached to the wall of the through hole, and will not push the accumulated liquid covering the through hole, which can avoid the situation where the dredging rod forcibly squeezes out large pieces of thick liquid that have not yet been broken and should not pass through the through hole when dredging the through hole, further improving the dispersion of the thick liquid, and when the end of the dredging rod completely passes through the through hole, the left end face of the dredging rod is flush with the right end face of the scraper, and then the threaded rod is rotated under the action of motor four, and the scraper moves up and down to scrape off the thick liquid attached to the end of the dredging rod, thereby avoiding the situation where the thick liquid follows the dredging rod and falls back into the through hole tube again when the dredging rod is reset, further ensuring the discharge of the accumulated liquid.

[0021] 2. The anti-fouling extraction device for drainage fluid used in nursing tumor patients described in the present invention can observe the extraction amount of the accumulated fluid by using the scale line, and can control the extraction amount according to actual needs, which is more convenient.

[0022] 3. The drainage fluid anti-fouling extractor for tumor patient care described in the present invention can seal the connection between the drainage hose and the liquid inlet pipe using a sealing ring, thereby preventing the accumulated fluid from overflowing through the connection between the drainage hose and the liquid inlet pipe and preventing the accumulated fluid from polluting the surrounding environment.

[0043] A drainage pipe 9 is provided at the middle of the lower right end of the drainage bucket 8, and a valve 10 is provided on the drainage pipe 9;

[0044] A threaded rod 15 is rotatably provided on the left side of the upper end surface of the partition 14, and the threaded rod 15 is threadedly connected to a scraper 16, and a sliding rod 33 is slidably connected to one side of the scraper 16, and the sliding rod 33 is slidably connected to the scraper 16, and the lower end of the sliding rod 33 is fixedly connected to the partition 14;

[0045] A motor 4 34 is fixedly connected to the middle of the left side of the lower end surface of the partition 14, and the output end of the motor 4 34 is fixedly connected to the lower end of the threaded rod 15;

[0046] Specifically, tumor patients often have effusion in the chest or abdominal cavity, which may cause the patient to experience discomfort symptoms such as dyspnea and abdominal distension. By extracting the effusion, these symptoms can be quickly relieved, and by performing a cytological examination on the effusion, it can provide doctors with important information about the patient's condition, thereby formulating a more accurate treatment plan. When the existing effusion extractor is in use, although it can cause the effusion to enter the drainage bucket 8 for collection by means of negative pressure suction, the effusion may contain relatively thick liquid. When a cytological examination is required, the cells in the viscous effusion may aggregate into clumps and are not easy to disperse, making it difficult to accurately count and identify cell types when observed under a microscope, which increases the difficulty of cytological examination.

[0047] Therefore, in order to solve the above problems, when the present embodiment is used, the extraction needle 5 is used to pierce the position to be extracted, and then the piston rod 6 is pulled to drive the piston 13 to move, so that the accumulated fluid is drawn into the extraction cylinder 1 through the extraction needle 5, and then enters the drainage barrel 8 through the drainage hose 2, and the one-way valve 4 can prevent the accumulated fluid from flowing back;

[0048] After the accumulated fluid enters the drainage barrel 8, it flows into the through-hole cylinder 12. If there is no thick liquid in the accumulated fluid, the accumulated fluid can flow out of the through-hole cylinder 12 through the through-hole 29 and be discharged through the drainage pipe 9. If there is thick liquid in the accumulated fluid, the thick liquid will not pass through the through-hole 29. Therefore, the motor three 30 and the motor five 32 can be started at the same time, and the motor five 32 drives the through-hole cylinder 12 to rotate, so that the thick liquid moves with the through-hole cylinder 12. At the same time, under the action of the motor three 30, the rotating shaft two 21 rotates, and the multiple bevel gears one 22 drive the multiple bevel gears two 23 to rotate, so that the multiple blades 19 can be rotated at the same time to break the thick liquid until the liquid can all pass through the through-hole 29, thereby obtaining a more dispersed accumulated fluid. In the subsequent cytological examination, the cell type can be accurately counted and identified, which reduces the difficulty of cytological examination.

[0049] Since the accumulated liquid passes through the through hole 29, small pieces of thick accumulated liquid may adhere to the hole wall of the through hole 29, and thick accumulated liquid may also adhere to the inner wall of the through hole cylinder 12, covering the through hole 29, which will affect the subsequent passage of the accumulated liquid. Therefore, when the through hole cylinder 12 rotates, the edge of the concave plate 18 will scrape against the inner wall of the through hole cylinder 12 to scrape off the thick liquid attached to the hole wall of the through hole cylinder 12, and whenever the through hole cylinder 12 rotates to a row When the through hole 29 is aligned with the position of the dredging rod 28, the motor 25 is started and drives the connecting rod 1 24 to rotate. Under the rotation of the connecting rod 1 24 and the connecting rod 26, the dredging rod 28 slides on the housing 17, so that the dredging rod 28 passes through the concave plate 18. When the dredging rod 28 passes through the through hole 29, the thick accumulated liquid attached to the wall of the through hole 29 can be pushed off, so as to avoid the thick accumulated liquid adhering to the wall of the through hole 29 and covering the through hole 29, thereby preventing the through hole 29 from being blocked, thereby ensuring The subsequent flow of accumulated liquid is prevented, and the dredging rod 28 is within the enclosure range of the concave plate 18 when dredging the through hole 29. Therefore, the dredging rod 28 will only push down the thick liquid attached to the wall of the through hole 29, and will not push the accumulated liquid covering the through hole 29. This can avoid the situation where the dredging rod 28 forcibly squeezes out large pieces of thick liquid that have not been broken and should not pass through the through hole 29 when dredging the through hole 29. The dispersion degree of the thick liquid is further improved. Moreover, when the end of the dredging rod 28 completely passes over the through hole 29, the left end face of the dredging rod 28 is flush with the right end face of the scraper 16. Then, under the action of the motor 4 34, the threaded rod 15 is rotated to move the scraper 16 up and down to scrape off the thick liquid attached to the end of the dredging rod 28, so as to avoid the situation that when the dredging rod 28 is reset, the thick liquid follows the dredging rod 28 and falls back into the through hole tube 12 again, thereby further ensuring the discharge of the accumulated liquid.

[0050] Thus, the anti-clogging viscous effusion crushing mechanism is utilized. When the effusion enters the drainage barrel 8, the motor five 32 drives the through-hole cylinder 12 to rotate, so that the thick liquid moves with the through-hole cylinder 12. At the same time, under the action of the motor three 30, the rotating shaft two 21 rotates, and the multiple bevel gears one 22 drive the multiple bevel gears two 23 to rotate, so that the multiple blades 19 can rotate at the same time to crush the thick liquid until the liquid can all pass through the through hole 29, thereby obtaining a more dispersed effusion. In the subsequent cytological examination, the cell type can be accurately counted and identified, reducing the difficulty of cytological examination. In addition, when the dredging rod 28 is dredging the through hole 29, it is within the enclosure range of the concave plate 18, so the dredging rod 28 will only remove the thick liquid attached to the wall of the through hole 29. The thick liquid is pushed down without pushing the accumulated liquid covering the through hole 29, which can avoid the situation that the dredging rod 28 forcibly squeezes out large pieces of thick liquid that have not yet been broken and should not pass through the through hole 29 when the dredging rod 28 is dredging the through hole 29, further improving the dispersion of the thick liquid, and when the end of the dredging rod 28 completely passes through the through hole 29, the left end face of the dredging rod 28 is flush with the right end face of the scraper 16, and then the threaded rod 15 is rotated under the action of the motor four 34, and the scraper 16 is moved up and down to scrape off the thick liquid attached to the end of the dredging rod 28, thereby avoiding the situation that the thick liquid follows the dredging rod 28 and falls back into the through hole tube 12 again when the dredging rod 28 is reset, further ensuring the discharge of the accumulated liquid.

[0051] In this embodiment, Figure 1 As shown, a scale line 7 is provided on the front side of the outer surface of the drainage bucket 8;

[0052] Specifically, the amount of fluid extracted can be observed using the scale line 7, and the amount of fluid extracted can be controlled according to actual needs, which is relatively convenient.

[0053] In this embodiment, Figure 4 As shown, a sealing ring 31 is provided at the upper end of the liquid inlet pipe 11;

[0054] Specifically, the sealing ring 31 can be used to seal the connection between the drainage hose 2 and the liquid inlet pipe 11, thereby preventing the accumulated liquid from overflowing through the connection between the drainage hose 2 and the liquid inlet pipe 11 and preventing the accumulated liquid from polluting the surrounding environment.

[0055] Working principle: Use the extraction needle 5 to pierce the position to be extracted, then pull the piston rod 6 to drive the piston 13 to move, and draw the accumulated fluid into the extraction tube 1 through the extraction needle 5, and enter the drainage barrel 8 through the drainage hose 2. The one-way valve 4 can prevent the accumulated fluid from flowing back. The scale line 7 can be used to observe the amount of accumulated fluid extracted, and the amount of extraction can be controlled according to actual needs, which is relatively convenient. The sealing ring 31 can be used to seal the connection between the drainage hose 2 and the liquid inlet pipe 11, avoiding the overflow of the accumulated fluid through the connection between the drainage hose 2 and the liquid inlet pipe 11, and preventing the accumulated fluid from polluting the surrounding environment; after the accumulated fluid enters the drainage barrel 8, it flows into the through-hole tube 12. If there is no thick liquid in the accumulated fluid, the accumulated fluid can be discharged through the through-hole 29 flows out of the through-hole cylinder 12 and is discharged through the drain pipe 9. If there is thick liquid in the effusion, the thick liquid will not pass through the through-hole 29. Therefore, the motor three 30 and the motor five 32 can be started at the same time, and the motor five 32 drives the through-hole cylinder 12 to rotate, so that the thick liquid moves with the through-hole cylinder 12. At the same time, under the action of the motor three 30, the rotating shaft two 21 rotates, and the multiple bevel gears one 22 drive the multiple bevel gears two 23 to rotate, so that the multiple blades 19 can be rotated at the same time to break the thick liquid until the liquid can all pass through the through-hole 29, thereby obtaining a more dispersed effusion. In the subsequent cytological examination, the cell type can be accurately counted and identified, which reduces the difficulty of cytological examination.Since the accumulated liquid passes through the through hole 29, small pieces of thick accumulated liquid may adhere to the hole wall of the through hole 29, and thick accumulated liquid may also adhere to the inner wall of the through hole cylinder 12, covering the through hole 29, which will affect the subsequent passage of the accumulated liquid. Therefore, when the through hole cylinder 12 rotates, the edge of the concave plate 18 will scrape against the inner wall of the through hole cylinder 12 to scrape off the thick liquid attached to the hole wall of the through hole cylinder 12, and whenever the through hole cylinder 12 rotates to a row When the through hole 29 is aligned with the position of the dredging rod 28, the motor 25 is started and drives the connecting rod 1 24 to rotate. Under the rotation of the connecting rod 1 24 and the connecting rod 26, the dredging rod 28 slides on the housing 17, so that the dredging rod 28 passes through the concave plate 18. When the dredging rod 28 passes through the through hole 29, the thick accumulated liquid attached to the wall of the through hole 29 can be pushed off, so as to avoid the thick accumulated liquid adhering to the wall of the through hole 29 and covering the through hole 29, thereby preventing the through hole 29 from being blocked, thereby ensuring The subsequent flow of accumulated liquid is prevented, and the dredging rod 28 is within the enclosure range of the concave plate 18 when dredging the through hole 29. Therefore, the dredging rod 28 will only push down the thick liquid attached to the wall of the through hole 29, and will not push the accumulated liquid covering the through hole 29. This can avoid the situation where the dredging rod 28 forcibly squeezes out large pieces of thick liquid that have not been broken and should not pass through the through hole 29 when dredging the through hole 29. The dispersion degree of the thick liquid is further improved. Moreover, when the end of the dredging rod 28 completely passes over the through hole 29, the left end face of the dredging rod 28 is flush with the right end face of the scraper 16. Then, under the action of the motor 4 34, the threaded rod 15 is rotated to move the scraper 16 up and down to scrape off the thick liquid attached to the end of the dredging rod 28, so as to avoid the situation that when the dredging rod 28 is reset, the thick liquid follows the dredging rod 28 and falls back into the through hole tube 12 again, thereby further ensuring the discharge of the accumulated liquid.Thus, the anti-clogging viscous effusion crushing mechanism is utilized. When the effusion enters the drainage barrel 8, the motor five 32 drives the through-hole cylinder 12 to rotate, so that the thick liquid moves with the through-hole cylinder 12. At the same time, under the action of the motor three 30, the rotating shaft two 21 rotates, and the multiple bevel gears one 22 drive the multiple bevel gears two 23 to rotate, so that the multiple blades 19 can rotate at the same time to crush the thick liquid until the liquid can all pass through the through hole 29, thereby obtaining a more dispersed effusion. In the subsequent cytological examination, the cell type can be accurately counted and identified, reducing the difficulty of cytological examination. In addition, when the dredging rod 28 is dredging the through hole 29, it is within the enclosure range of the concave plate 18, so the dredging rod 28 will only remove the thick liquid attached to the wall of the through hole 29. The thick liquid is pushed down without pushing the accumulated liquid covering the through hole 29, which can avoid the situation that the dredging rod 28 forcibly squeezes out the large chunks of thick liquid that have not been broken and should not pass through the through hole 29 when the dredging rod 28 dredges the through hole 29, further improving the dispersion of the thick liquid. Moreover, when the end of the dredging rod 28 completely passes through the through hole 29, the left end face of the dredging rod 28 is flush with the right end face of the scraper 16, and then the threaded rod 15 is rotated under the action of the motor 434, so that the scraper 16 moves up and down to scrape off the thick liquid attached to the end of the dredging rod 28, so as to avoid the situation that when the dredging rod 28 is reset, the thick liquid follows the dredging rod 28 and falls back into the through hole tube 12 again, further ensuring the discharge of the accumulated liquid.
