Description

Technical Field

[0001] This utility model relates to the field of liquid tumor aspiration technology, specifically a device for aspirating liquid tumors. Background Technology

[0002] In the medical field, the treatment and diagnosis of liquid tumors (such as certain types of cyst fluid, malignant ascites, etc.) often require precise and efficient aspiration. Traditional liquid tumor aspiration devices mainly rely on the pump principle, using negative pressure to extract the liquid tumor from the patient's body.

[0003] In the process of pumping liquid tumor aspiration devices in the prior art, it is often inevitable that surrounding tissues such as cell debris, connective tissue, and blood vessel wall fragments will be pumped in at the same time. These tissues mix with the liquid tumor to form a complex mixture. In order to separate pure liquid tumor from this mixture, secondary filtration is usually required. The secondary filtration process increases the complexity of the operation. At the same time, the secondary filtration process may also introduce additional contamination risks, such as microbial contamination and chemical contamination of the filter itself, which may threaten the integrity and safety of the liquid tumor sample.

Hole blocks are fixed on both sides of the outer wall of the ring, and magnetic posts 1 are fixed in the inner hole of the hole block, and the opposing surfaces of magnetic posts 1 and magnetic posts 2 are magnetically attracted to each other.

[0014] As an improved technical solution, a retaining ring is fixed inside the ring and near one end of the horizontal tube. Magnetic pillars are embedded in the opposing surfaces of the retaining ring and the filter screen, and the opposing surfaces of the two magnetic pillars are in a magnetic adsorption state.

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.

[0027] Please see Figures 1-5 This utility model proposes a technical solution: a device for aspirating liquid tumors, comprising: a negative pressure pump 1, a filter assembly 2, and a suction head 3. The negative pressure pump 1 and the suction head 3 are connected through the filter assembly 2. A connecting pipe 11 is fixedly connected to the negative pressure inlet of the negative pressure pump 1. The connecting pipe 11 is transitionally connected to the horizontal pipe 21. A corrugated pipe 31 is fixedly connected to the end of the suction head 3 near the filter assembly 2. A connecting pipe 32 is fixedly connected to the end of the corrugated pipe 31 near the filter assembly 2. The connecting pipe 32 is transitionally connected to the horizontal pipe 22. The horizontal pipe 21 and the connecting pipe 11, as well as the connecting pipe 32 and the horizontal pipe 22, are all transitionally connected. That is, the filter assembly 2 is in a detachable connection state. After each use, the filter assembly 2 can be disassembled, recycled, and disinfected to ensure its cleanliness each time it is used.

[0028] The filter assembly 2 includes a horizontal tube 1 21 and a horizontal tube 22. A bracket 24 is fixed on both the horizontal tube 1 21 and the horizontal tube 22. A filter body 23 is installed between the opposite ends of the horizontal tube 1 21 and the horizontal tube 22. An internal threaded connector is fixed to the bottom of the horizontal tube 1 21. A storage bottle 25 is threaded onto the horizontal tube 1 21 through the internal threaded connector. An external thread is provided at the bottle mouth of the storage bottle 25.

[0029] The filter body 23 includes a drive shaft 236 rotatably installed between the first horizontal tube 21 and the second horizontal tube 22. A triangular block 237 is fixedly connected to one end of the drive shaft 236 near the first horizontal tube 21. A ring 239 is fixedly connected to each triangular end of the triangular block 237. A filter screen 2310 is installed inside the ring 239.

[0030] The tissue in the liquid tumor is filtered and separated by the filter body 23 on the filter assembly 2. The clean tumor is then stored inside the storage bottle 25. The built-in filter eliminates the need for secondary filtration of the liquid tumor, simplifying the operation process. At the same time, filtration and pumping are carried out simultaneously, avoiding additional contamination risks during the filtration of liquid tumor and preserving the integrity and safety of the liquid tumor sample.

[0031] The filter body 23 also includes a fixing sleeve 232 installed on the end of the horizontal tube 22 near the end of the horizontal tube 1 21, and a fixing sleeve 3 233 installed on the end of the horizontal tube 1 21 near the end of the horizontal tube 22. A shaft block 238 is fixedly installed on the top of the fixing sleeve 232, and the shaft block 238 is rotatably connected to the drive shaft 236 through a bearing installed on it.

[0032] Fixed sleeve 231 is fixedly installed at the end of fixed sleeve 232 away from horizontal tube 21. A vertical shaft 235 is rotatably installed at the top horizontal end of fixed sleeve 231 via a bearing, and a knob is installed at the top of vertical shaft 235. A bevel gear transmission component 234 is installed between vertical shaft 235 and the end of transmission shaft 236 near vertical shaft 235. The bevel gear transmission component 234 consists of two meshing bevel gears. Three filter screens 2310 are provided on filter body 23. Drive vertical shaft 235 to rotate. Under the transmission action of bevel gear transmission component 234, transmission shaft 236 rotates with vertical shaft 235, which drives three rings 239 to rotate synchronously, adjusting the position of the three filter screens 2310 so that the three filter screens 2310 are alternately located between the opposite ends of horizontal tube 21 and horizontal tube 22, realizing the switching of filter screens 2310 for use, which is convenient for switching the clogged filter screens 2310.

[0033] The bottom end of the fixed sleeve 232 is integrally formed with a connecting strip 2314, and the bottom end of the fixed sleeve 3 233 is integrally formed with a connecting strip 2318. Both ends of the connecting strip 2314 are provided with T-shaped holes, and the interior of the T-shaped holes is provided with a smooth bolt 2317. The connecting strip 2318 is coaxially formed with a through hole at the position of the two smooth bolts 2317. The threaded part of the smooth bolt 2317 and the side of the connecting strip 2318 away from the connecting strip 2314 are threaded with a wing nut 2316.

[0034] A spring 2315 is fitted on the smooth bolt 2317 and located between the connecting strip 1 2314 and the connecting strip 2318. The wing nut 2316 rotates on the smooth bolt 2317. The wing nut 2316 moves against the connecting strip 2318 towards the connecting strip 1 2314, shortening the gap between the fixing sleeve 232 and the fixing sleeve 3 233. This clamps the ring 239 between the fixing sleeve 232 and the fixing sleeve 3 233, improving the sealing performance and preventing leakage. Furthermore, rotating the wing nut 2316 away from the fixing sleeve 232, under the elastic action of the spring 2315, pushes the fixing sleeve 3 233 away from the fixing sleeve 232, quickly widening the gap between the fixing sleeve 232 and the fixing sleeve 3 233.

[0035] Magnetic posts 2313 are embedded on both sides of the opposite surfaces of fixed sleeve 232 and fixed sleeve 333. The opposite surfaces of magnetic posts 2313 on fixed sleeve 232 and fixed sleeve 323 are magnetically attracted to each other. Hole blocks 2311 are fixed on both sides of the outer wall of ring 239. Magnetic posts 2312 are fixed in the inner holes of hole blocks 2311. Magnetic posts 2312 and magnetic posts 2313 are magnetically attracted to each other. When ring 239 is located between horizontal tube 22 and horizontal tube 21, magnetic posts 2313 and magnetic posts 2312 are magnetically attracted to each other, thus positioning and reinforcing the ring 239.

[0036] Inside the ring 239 and near one end of the horizontal tube 21, a retaining ring 2319 is fixed. Magnetic posts 3 are embedded in the opposing surfaces of the retaining ring 2319 and the filter screen 2310, and the opposing surfaces of the two magnetic posts 3 are in a magnetic adsorption state. The filter screen 2310 is fixed inside the ring 239 by the magnetic adsorption of the magnetic posts 3, which facilitates the quick installation and removal of the filter screen 2310 inside the ring 239 and improves work efficiency.

[0037] The working principle of this utility model is as follows:

[0038] When in use, hold the suction head 3 and turn on the negative pressure pump 1. Under the negative pressure of the negative pressure pump 1, the liquid tumor enters the interior of the filter assembly 2 through the suction head 3, the bellows 31 and the connecting pipe 32.

[0039] The process by which the liquid tumor enters the filter assembly 2 is as follows:

[0040] The liquid tumor, mixed with tissue, enters the horizontal tube 22. After the tissue inside the liquid tumor is filtered by the filter body 23, the liquid tumor flows downstream through the filter body 23 and enters the horizontal tube 21. Finally, it enters the storage bottle 25 through the internal threaded connector for storage. This achieves the effect that when the liquid tumor is pumped, the tissue in the liquid tumor is filtered and separated by the filter body 23 on the filter assembly 2, and the clean tumor is finally stored in the storage bottle 25.

[0041] 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
