[0002] Due to the differences in the survival characteristics of microorganisms and the comprehensive requirements of clinical diagnosis, the oscillating liquid in the surgical area, tissue or prosthesis needs to be discharged into anaerobic bottles and aerobic bottles at the same time. By covering all possible pathogen growth conditions, the infection detection rate can be significantly improved, precise medication can be guided, and international testing standards can be met.

[0003] Before sampling, the oscillated liquid in the surgical area, tissue or prosthesis is centrifuged and the precipitate is discarded to avoid clogging the filling tools or interfering with microbial detection.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0022] Please refer to the attached Figure 1 To Attachment Figure 7 An ultrasonic oscillation automatic sampler of the present invention is described.

[0023] Before sampling, the oscillated liquid in the surgical area, tissue or prosthesis is centrifuged and the precipitate is discarded to avoid clogging the filling tools or interfering with microbial detection. It is then filled into anaerobic bottles and aerobic bottles. When injecting into the anaerobic bottle, a sterile syringe or pipette is needed to quickly inject the liquid into the anaerobic bottle to avoid exposure to oxygen and ensure an anaerobic environment in the bottle.

[0024] However, when the operation is performed using a sterile syringe or pipette, it relies on manual operation, which may mix oxygen into the anaerobic bottle when the shaking liquid is injected into the anaerobic bottle, causing direct toxicity to anaerobic microorganisms, thereby interfering with the culture results, misleading the etiological analysis, and failing to guide clinical medication.

[0025] Therefore, the ultrasonic oscillation automatic sampler includes a shell 1, a sampling door 11 is provided in the shell 1, and the anaerobic bottle 3 and the aerobic bottle 31 can be prevented from entering the sampling area by opening the sampling door 11. A rotating disk 12 is provided in the shell 1, and the rotating disk 12 can rotate relative to the shell 1. An anaerobic sampling component 28 and an aerobic sampling component 29 are provided in the shell 1. The anaerobic sampling component 28 and the aerobic sampling component 29 are both connected to the rotating disk 12. When the rotating disk 12 rotates, the anaerobic sampling component 28 can discharge the oscillated liquid to the anaerobic bottle 3. Because the anaerobic bottle 3 is filled with nitrogen to maintain an anaerobic environment before the oscillation liquid enters, and when the oscillation liquid enters the anaerobic bottle 3, the nitrogen in the anaerobic bottle 3 is discharged. The gas is discharged into the storage bottle 32 under pressure. Since the density of nitrogen is lower than that of oxygen, when the oscillating liquid enters the anaerobic bottle 3, the nitrogen in the anaerobic bottle 3 is located above the anaerobic bottle 3, thereby ensuring that the gas entering the storage bottle 32 is nitrogen. When the nitrogen in the storage bottle 32 reaches the first upper limit, the nitrogen stops being discharged into the storage bottle 32. The remaining gas may be mixed with oxygen or other gases, thereby discharging the remaining gas in the anaerobic bottle 3 through the anaerobic sampling component 28. After the remaining gas in the anaerobic bottle 3 is discharged, the storage bottle 32 discharges the nitrogen to the anaerobic bottle 3 again, ensuring that the anaerobic bottle 3 remains in an anaerobic environment. The aerobic sampling component 29 can discharge the oscillating liquid to the aerobic bottle 31.

[0026] Regarding the rotating disk 12, the supporting frame 14 can be used to limit the rotating disk 12 so that the rotating disk 12 can only rotate. The rotating disk 12 can be a gear, and other gears are engaged with the teeth on the rotating disk 12 to drive the rotating disk 12 to rotate. The rotating disk 12 can also be a pulley, and other pulleys and belts are used to drive the rotating disk 12 to rotate. In other embodiments of the present invention, other structures can be used as long as it can ensure that the rotating disk 12 can rotate.

When the nitrogen in the storage bottle 32 reaches a first upper limit, the gas in the anaerobic bottle 3 is discharged to the anaerobic sampling assembly 28 through the fourth pipeline 7.

[0029] The first pipeline 4 includes a first connecting pipe 41, a first switching valve 43, and a second connecting pipe 42. The first switching valve 43 is provided with a first inlet, a second inlet, and a first outlet. The first inlet of the first switching valve 43 is connected to the first connecting pipe 41, the second inlet of the first switching valve 43 is connected to the fourth pipeline 7, the first outlet of the first switching valve 43 is connected to the second connecting pipe 42, and the first switching valve 43 is provided with a first connected state and a second connected state. When the first switching valve 43 is in the first communication state, the first connecting pipe 41 is connected to the second connecting pipe 42 through the first switching valve 43 to absorb the oscillating liquid into the anaerobic sampling assembly 28; When the first switching valve 43 is in the second connection state, the fourth pipeline 7 is connected to the second connecting pipe 42 through the first switching valve 43, so that when the nitrogen in the storage bottle 32 reaches the first upper limit, the gas in the anaerobic bottle 3 is discharged to the anaerobic sampling assembly 28.

[0030] The second pipeline 5 includes a third connecting pipe 51, a second switching valve 53 and a fourth connecting pipe 52. The second switching valve 53 is provided with a third inlet, a second outlet and a third outlet. The third inlet of the second switching valve 53 is connected to the third connecting pipe 51, the second outlet of the second switching valve 53 is connected to the fourth connecting pipe 52, the third outlet of the second switching valve 53 is connected to the fifth pipeline 8, and the second switching valve 53 is provided with a third connection state and a fourth connection state. When the second switching valve 53 is in the third connection state, the third connecting pipe 51 is connected to the fourth connecting pipe 52 through the second switching valve 53 to discharge the oscillating liquid in the anaerobic sampling assembly 28 into the anaerobic bottle 3; When the second switching valve 53 is in the fourth communication state, the third connecting pipe 51 is connected to the fifth pipeline 8 through the second switching valve 53 to discharge the gas in the anaerobic sampling assembly 28 .

[0031] The third pipeline 6 includes a fifth connecting pipe 61, a third switching valve 63 and a sixth connecting pipe 62. The third switching valve 63 is provided with a fourth inlet, a fourth outlet and a fifth outlet. The fourth inlet of the third switching valve 63 is connected to the fifth connecting pipe 61, the fourth outlet of the third switching valve 63 is connected to the sixth connecting pipe 62, the fifth outlet of the third switching valve 63 is connected to the fourth pipeline 7, and the third switching valve 63 is provided with a fifth connection state and a sixth connection state. When the third switching valve 63 is in the fifth communication state, the fifth connecting pipe 61 is connected to the sixth connecting pipe 62 through the third switching valve 63 to discharge the nitrogen in the anaerobic bottle 3 into the storage bottle 32; When the third switching valve 63 is in the sixth communication state, the fifth connecting pipe 61 is connected to the fourth pipeline 7 through the third switching valve 63 to discharge the gas in the anaerobic bottle 3 .

[0032] The sampler also includes a sixth pipeline 9, and the storage bottle 32 is connected to the anaerobic bottle 3 through the sixth pipeline 9. A connecting valve 91 is provided at the connection between the sixth pipeline 9 and the storage bottle 32. The opening and closing of the connecting valve 91 controls whether the storage bottle 32 and the anaerobic bottle 3 are connected through the sixth pipeline 9. After the gas in the anaerobic bottle 3 is discharged, the connecting valve 91 is started, and the storage bottle 32 discharges nitrogen to the anaerobic bottle 3 through the sixth pipeline 9.

[0033] See also Figure 6 First, the first switching valve 43 is in the first connection state, so that the first connecting pipe 41 is connected with the second connecting pipe 42 through the first switching valve 43, so as to absorb the oscillated liquid into the anaerobic sampling assembly 28. The second switching valve 53 is in the third connection state, and the third connecting pipe 51 is connected with the fourth connecting pipe 52 through the second switching valve 53. The oscillated liquid in the anaerobic sampling assembly 28 is discharged into the anaerobic bottle 3 through the third connecting pipe 51 and the fourth connecting pipe 52. The third switching valve 63 is in the fifth connection state. Before the oscillation liquid enters the anaerobic bottle 3, the anaerobic bottle 3 is filled with sufficient nitrogen to maintain an anaerobic environment. When the oscillation liquid enters the anaerobic bottle 3, the nitrogen in the anaerobic bottle 3 is pressurized and discharged into the storage bottle 32. Since the density of nitrogen is lower than that of oxygen, when the oscillation liquid enters the anaerobic bottle 3, the nitrogen in the anaerobic bottle 3 is located above the anaerobic bottle 3, thereby ensuring that the nitrogen enters the storage bottle 32.

[0034] See also Figure 7When the nitrogen in the storage bottle 32 reaches the first upper limit, the third switching valve 63 is switched from the fifth connection state to the sixth connection state, the first switching valve 43 is switched from the first connection state to the second connection state, and the second switching valve 53 is switched from the third connection state to the fourth connection state. At this time, the anaerobic sampling assembly 28 is connected to the anaerobic bottle 3 through the second connecting pipe 42, the fourth pipeline 7 and the fifth connecting pipe 61, so that the anaerobic sampling assembly 28 transfers the remaining gas in the anaerobic bottle 3 through the second connecting pipe 42, the fourth pipeline 7 and the fifth connecting pipe 61. The remaining gas may be mixed with oxygen or other gases, and then the remaining gas in the anaerobic bottle 3 is discharged through the anaerobic sampling component 28, the third connecting pipe 51 and the fifth pipeline 8. After the discharge is completed, the anaerobic sampling component 28 stops running, and the connecting valve 91 is started, so that the storage bottle 32 is connected to the anaerobic bottle 3 through the sixth pipeline 9. At this time, the anaerobic bottle 3 is in a negative pressure state, so that the ammonia in the storage bottle 32 is sucked into the anaerobic bottle 3, ensuring that the anaerobic bottle 3 is kept in an anaerobic environment, ensuring the accuracy of the culture results, so as to correctly guide clinical medication.

[0035] The aerobic sampling assembly 29 is connected to a seventh pipeline 33 and an eighth pipeline 34 , and the oscillating liquid is sucked into the aerobic sampling assembly 29 through the seventh pipeline 33 . The aerobic sampling pipeline is connected to the aerobic bottle 31 through the eighth pipeline 34 to discharge the oscillating liquid into the aerobic bottle 31 .

[0036] A pressure sensor is provided in the storage bottle 32 to detect the amount of nitrogen in the storage bottle 32. When the nitrogen in the storage bottle 32 reaches a first upper limit, the pressure sensor controls the storage bottle 32 to cancel the connection with the anaerobic bottle 3, and the gas in the anaerobic bottle 3 is discharged. Specifically, when the nitrogen in the storage bottle 32 reaches the first upper limit, the third switching valve 63 is switched from the fifth connection state to the sixth connection state, the first switching valve 43 is switched from the first connection state to the second connection state, and the second switching valve 53 is switched from the third connection state to the fourth connection state.

[0037] Preferably, the first connecting pipe 41, the second connecting pipe 42, the third connecting pipe 51, the fourth connecting pipe 52, the fifth connecting pipe 61, the sixth connecting pipe 62, the fourth pipeline 7, the fifth pipeline 8, the sixth pipeline 9, the seventh pipeline 33 and the eighth pipeline 34 are all provided with a one-way valve.

[0038] The sampling assembly 2 includes a sampling bottle 21, in which a sealing plug 22 is slidably connected. A piston rod 23 is hinged on the sealing plug 22. A first ring 24 is fixedly connected to the piston rod 23. The first ring 24 is sleeved on a connecting rod 25. The connecting rod 25 is eccentrically connected to the rotating disk 12 so that when the rotating disk 12 rotates, the sealing plug 22 slides back and forth along the sampling bottle 21.

[0039] When the sealing plug 22 slides upward along the sampling bottle 21, negative pressure is generated in the sampling bottle 21, so that the oscillating liquid is sucked into the sampling bottle 21 through the first connecting tube 41 and the second connecting tube 42, or the remaining gas in the anaerobic bottle 3 is sucked into the sampling bottle 21 through the second connecting tube 42, the fourth pipeline 7 and the fifth connecting tube 61. When the sealing plug 22 slides downward along the sampling bottle 21, positive pressure is generated in the sampling bottle 21, so that the oscillating liquid is discharged into the anaerobic bottle 3 through the third connecting tube 51 and the fourth connecting tube 52, or the remaining gas in the anaerobic bottle 3 is discharged through the third connecting tube 51 and the fifth pipeline 8.

[0040] The rotating disk 12 is provided with a slide groove 13, and the connecting rod 25 is slidably connected to the slide groove 13. The rotating disk 12 is fixedly connected with a cylinder 26, and the output end of the cylinder 26 is fixedly connected with a second ring 27, and the second ring 27 is sleeved with the connecting rod 25. The displacement of the connecting rod 25 along the slide groove 13 is controlled by the sliding amount of the output end of the cylinder 26 to control the discharge amount of the oscillating liquid or the discharge amount of the gas. Specifically, when the cylinder 26 drives the connecting rod 25 to approach the center of the rotating disk 12, the piston rod 23 drives the seal The sliding stroke of the plug 22 along the sampling bottle 21 is reduced, so that the discharge amount of the oscillating liquid is reduced, which is convenient for manual control of the amount of oscillating liquid required for the anaerobic bottle 3 and the aerobic bottle 31, and the discharge amount of the gas is also reduced. When the cylinder 26 drives the connecting rod 25 away from the center of the rotating disk 12, the piston rod 23 drives the sealing plug 22 to increase its sliding stroke along the sampling bottle 21, thereby increasing the discharge amount of the oscillating liquid, which is convenient for manual control of the amount of oscillating liquid required for the anaerobic bottle 3 and the aerobic bottle 31, and the discharge amount of the gas is also increased.
