[0025] Depend on Figures 1 to 3 As shown, this utility model includes a cylinder 10 disposed on one side of the vehicle body 1, a cylinder cover 14 fastened to the cylinder 10, a feed pipe 101 passing through the cylinder cover 14 and communicating with the cylinder 10, a filter assembly disposed inside the cylinder 10, and a centrifuge mechanism disposed on the other side of the vehicle body 1. A flow guide assembly is provided between the cylinder 10 and the centrifuge mechanism. In use, the blood and tissue generated during the curettage procedure are drawn into the cylinder 10 and separated into solid and liquid components by the filter assembly. The separated blood then flows into the centrifuge mechanism through the flow guide assembly, quickly achieving the operation of blood centrifugation and stratification.
[0026] Specifically, the filter assembly includes a filter plate 12 fixedly disposed on the inner wall of the cylinder 10 and a sleeve rod 11 connected to the lower end of the filter plate 12. The filter plate 12 has a tapered structure that is wider at the top and narrower at the bottom. A cleaning assembly for cleaning the filter plate 12 is also provided on the cylinder 10.
[0027] The cleaning assembly includes a rotating rod 2 that passes through the cylinder cover 14 and is inserted into the cylinder body 10. The insertion end of the rotating rod 2 is sleeved downward on the sleeve rod 11. The protruding end of the rotating rod 2 is provided with a horizontally extending connecting rod 21. The protruding end of the connecting rod 21 is provided with a vertically extending support rod 22. The protruding end of the support rod 22 is provided with a scraper 23 that fits against the outer wall of the filter plate 12. A square column section is provided on the rotating rod 2. A turntable 20 is sleeved on the outside of the square column section. A limiting rod 24 is screwed into the cylinder body 10. The upper end face of the limiting rod 24 fits against the end face of the protruding end of the rotating rod 2.
[0028] A sealing door 13 is provided on the lower part of the side wall of the cylinder 10.
[0029] The flow guiding assembly includes a drain hose 3 connected to the lower end of the cylinder 10. A filter screen 15 is provided on the cylinder 10 at the position corresponding to the connection between the drain hose 3 and the cylinder 10. A switch valve 30 is provided at the outlet end of the drain hose 3.
[0030] The centrifuge mechanism includes a servo motor 4 fixed on the vehicle body 1, a transmission rod 40 connected to the output end of the servo motor 4 and extending upward through the vehicle body 1, and a placement cylinder 41 connected to the transmission rod 40. Three test tube slots 42 for placing test tubes are evenly arranged in the circumferential direction inside the placement cylinder 41. A partition cylinder 43 connected and fixed to the vehicle body 1 is arranged around the outside of the placement cylinder 41. A cover 44 is fastened on the side of the partition cylinder 43 corresponding to the slot opening of the test tube slots 42. The cover 44 is made of acrylic sheet.
[0031] A power supply 5 connected to the servo motor 4 is provided on the vehicle body 1; a push handle 16 is provided on the vehicle body 1.
[0032] The working principle of this utility model is as follows:
[0033] like Figures 1 to 3 As shown, the power supply 5 in this embodiment uses a storage battery, which is small in size and occupies little space; while using a servo motor 4, under the premise that the storage battery can drive the placement cylinder 41 to meet the centrifugal speed requirements, it also reduces the installation space and can prevent movement interference.
[0034] During installation, a filter screen 15 is installed inside the cylinder 10 at the connection point between the drain hose 3 and the cylinder 10. Then, a rotating rod 20 is sleeved onto a sleeve rod 11 and extends downwards through the sleeve rod 11. A horizontally extending connecting rod 21 is connected to this extending end. A vertically extending support rod 22 is provided at the extended end of the connecting rod 21. A scraper 23, which fits against the outer wall of the filter plate 12, is provided at the extended end of the support rod 22. Thus, rotating the rotating rod 20 drives the scraper 23 to clean the filter. The lower end face of plate 12 is fitted and rotated. At the same time, a limiting rod 24 is screwed into the cylinder 10. The upper end face of the limiting rod 24 is fitted and abutted against the end face of the end through which the rotating rod 2 passes. In this way, while allowing the rotating rod 2 to rotate, it can prevent the rotating rod 2 from moving downward and causing the scraper 23 to detach from the filter plate 12 and fail to function. The screwed-on limiting rod 24 is also easy to disassemble and use. Then, the sealing door 13 is fastened to achieve the sealing of the lower part of the cylinder 10.
[0035] Before use, the cylinder cover 14 with the feed pipe 101 is placed on the rotating rod 2 and then fastened to the cylinder body 10. The turntable 20 is then attached to the square column section of the rotating rod 2 so as to drive the rotating rod 2 to rotate. The switch valve 30 is in the closed state.
[0036] During use, the tissue and blood from the uterus are extracted by a component used in the curettage procedure (not labeled) and discharged into the cylinder 10 through the feed tube 101. The tissue and blood entering the cylinder 10 undergo rapid solid-liquid separation at the filter plate 12, facilitating the rapid extraction of tissue samples post-procedure. The separated blood is temporarily stored in the cylinder 10 below the filter plate 12. When blood needs to be extracted for testing, the test tube is removed, the drain tube 3 is pulled out and aligned with the test tube opening, and the valve 30 is opened. After a certain amount of blood is discharged, the valve 30 is closed. Then, the test tube containing the blood is placed in the test tube trough 42, the cover 44 is fastened on the separator 43, and the servo motor 4 is turned on to centrifuge the blood in a timely manner. Therefore, the drain tube 3 is a gooseneck tube, which allows the tube to be bent and placed freely without the need for supporting components, making it convenient to use.
[0037] After centrifugation, turn off the servo motor 4, open the cover 44, remove the test tube, and send it for testing in a timely manner. The entire process is synchronized with the surgical procedure, which can effectively prevent inconvenience caused by blood coagulation and save the testing cycle, thereby improving the accuracy of the test. Three test tube slots 42 are set up to facilitate the continuous testing of the extracted blood after centrifugation in batches, so as to ensure the accuracy of the test results.
[0038] It should be noted that, during use, in order to prevent small tissues from falling into the filtered blood through the filter plate 12, a filter screen 15 is provided at the connection between the drain hose 3 and the cylinder 10 to filter the blood a second time, so as to ensure the accuracy and stability of the blood centrifugation process.
[0039] In addition, during use, if a large amount of tissue is extracted, in order to prevent clogging at the filter plate 12, the turntable 20 is manually rotated, and the connecting rod 21 and the support rod 22 drive the scraper 23 to rotate synchronously. Since the scraper 23 is set to fit against the outer wall of the filter plate 12, it can scrape off the residual tissue on the filter plate 12 and maintain the smooth filtration of the filter plate 12.
[0040] After the operation, open the valve 30 to drain the remaining blood through the drainage hose 3. At the same time, remove the attached turntable 20 and then remove the cylinder cover 14. The aspirated tissue specimen can be directly taken from the filter plate 12. Finally, rinse the cylinder 10 with clean water. At this time, the sealing door 13 should be opened to manually remove tissue residue inside the cylinder 10 and clean the filter screen 15 and the lower end face of the filter plate 12. The turntable 20 can be reinstalled to rotate the scraper 23 again to clean the filter plate 12. The contact area between the scraper 23 and the filter plate 12 can also be directly rinsed to avoid the formation of cleaning dead corners.
[0041] In this embodiment, the cover 44 is preferably made of a visible material, preferably an acrylic sheet, which not only prevents damage from drops, but also facilitates observation of the centrifugal rotation status and allows for timely shutdown of the servo motor 4.
[0042] In addition, the setting of the sealing door 13 is consistent with the prior art. Simply put, a notch is set on the cylinder 10, and the sealing door 13 is set at the notch position. At the same time, a sealing ring is set on the notch wall (or the outer wall of the sealing door) so that it can fit and abut against the sealing door 13 (or the notch wall) to form a seal. This not only makes it easy to use, but also makes it easy to replace the sealing ring in time.
[0043] This utility model uses a vehicle body 1 as a carrier and a push handle 16 is provided on the vehicle body 1 to facilitate movement and storage in the operating room. It can also improve the efficiency of transfer between other departments when needed, making it flexible and convenient to use.
[0044] In this embodiment, the connection between the feed tube 101 and the components used in the curettage procedure, as well as the relevant treatment of the blood before centrifugation, are consistent with the prior art and will not be described again here.
