Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an ultrasonic oscillation automatic sampler. Background Art

[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 simultaneously discharged into an anaerobic bottle and an aerobic bottle. By covering all possible pathogen growth conditions, the infection detection rate can be significantly improved, precise medication can be guided, and international detection standards can be met.

[0003] Before sampling the oscillating liquid in the surgical area, tissue or prosthesis, it is centrifuged to discard the precipitate to avoid clogging the dispensing tool or interfering with microbial detection, and then it is dispensed into an anaerobic bottle and an aerobic bottle. 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 inside the bottle.

[0004] However, when operating with a sterile syringe or pipette, it relies on manual operation. Human operation may mix oxygen when injecting the oscillating liquid into the anaerobic bottle, which has a direct toxicity to anaerobic microorganisms, thus interfering with the culture results and misleading the etiological analysis, and unable to guide clinical medication.

[0005] Therefore, there is an urgent need to design an ultrasonic oscillation automatic sampler to solve the above-mentioned problems. Summary of the Invention

An anaerobic sampling component and an aerobic sampling component are provided inside the housing, and both the anaerobic sampling component and the aerobic sampling component are connected to the rotating disk. When the rotating disk rotates, the anaerobic sampling component can discharge the oscillating liquid into the anaerobic bottle, and the nitrogen gas in the anaerobic bottle is discharged into the storage bottle. When the nitrogen gas in the storage bottle reaches the first upper limit, the anaerobic sampling component discharges the gas in the anaerobic bottle. After the gas in the anaerobic bottle is discharged, the storage bottle discharges nitrogen gas into the anaerobic bottle, and the aerobic sampling component can discharge the oscillating liquid into the aerobic bottle.

[0009] Further, the anaerobic sampling assembly is connected with a first pipeline and a second pipeline. The oscillating liquid is sucked into the anaerobic sampling assembly through the first pipeline. The anaerobic sampling assembly is connected with an anaerobic bottle through the second pipeline to discharge the oscillating liquid into the anaerobic bottle. A third pipeline is connected to the anaerobic bottle, and the anaerobic bottle is connected with a storage bottle through the third pipeline to discharge the nitrogen gas in the anaerobic bottle into the storage bottle. A fourth pipeline is connected to the first pipeline and the third pipeline. When the nitrogen gas in the storage bottle reaches the first upper limit, the gas in the anaerobic bottle is discharged into the anaerobic sampling assembly through the fourth pipeline. A fifth pipeline is connected to the second pipeline, and the gas in the anaerobic sampling assembly is discharged through the fifth pipeline.

[0010] Further, the first pipeline includes a first connecting pipe, a first switching valve, and a second connecting pipe. The first switching valve is provided with a first inlet, a second inlet, and a first outlet. The first inlet of the first switching valve is connected to the first connecting pipe, the second inlet of the first switching valve is connected to the fourth pipeline, and the first outlet of the first switching valve is connected to the second connecting pipe. The first switching valve has a first connected state and a second connected state;

[0011] When the first switching valve is in the first connected state, the first connecting pipe is connected to the second connecting pipe through the first switching valve to suck the oscillating liquid into the anaerobic sampling assembly;

[0012] When the first switching valve is in the second connected state, the fourth pipeline is connected to the second connecting pipe through the first switching valve, so that when the nitrogen gas in the storage bottle reaches the first upper limit, the gas in the anaerobic bottle is discharged into the anaerobic sampling assembly.

[0013] Further, the second pipeline includes a third connecting pipe, a second switching valve, and a fourth connecting pipe. The second switching valve is provided with a third inlet, a second outlet, and a third outlet. The third inlet of the second switching valve is connected to the third connecting pipe, the second outlet of the second switching valve is connected to the fourth connecting pipe, and the third outlet of the second switching valve is connected to the fifth pipeline. The second switching valve has a third connected state and a fourth connected state;

[0014] When the second switching valve is in the third connected state, the third connecting pipe is connected to the fourth connecting pipe through the second switching valve to discharge the oscillating liquid in the anaerobic sampling assembly into the anaerobic bottle;

[0015] When the second switching valve is in the fourth connected state, the third connecting pipe is connected to the fifth pipeline through the second switching valve to discharge the gas in the anaerobic sampling assembly.

[0016] Further, the third pipeline includes a fifth connecting pipe, a third switching valve, and a sixth connecting pipe. The third switching valve is provided with a fourth inlet, a fourth outlet, and a fifth outlet. The fourth inlet of the third switching valve is connected to the fifth connecting pipe, the fourth outlet of the third switching valve is connected to the sixth connecting pipe, and the fifth outlet of the third switching valve is connected to the fourth pipeline. The third switching valve has a fifth connected state and a sixth connected state;

[0018] When the third switching valve is in the sixth connection state, the fifth connecting pipe is connected to the fourth pipeline through the third switching valve to discharge the gas in the anaerobic bottle.

[0019] Furthermore, it further includes a sixth pipeline. The storage bottle is connected to the anaerobic bottle through the sixth pipeline. A connecting valve is provided at the connection between the sixth pipeline and the storage bottle. Whether the storage bottle and the anaerobic bottle are connected through the sixth pipeline is controlled by the opening and closing of the connecting valve. After the gas in the anaerobic bottle is discharged, the connecting valve is activated, and the storage bottle discharges nitrogen gas into the anaerobic bottle through the sixth pipeline.

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. 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.

[0034] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0035] The following refers to the attached Figure 1 to the attached Figure 7 Describe an ultrasonic oscillation automatic sampler of the present invention.

[0036] Before sampling, the oscillating liquid in the surgical area, tissue or prosthesis is centrifuged, and the precipitate is discarded to avoid clogging the dispensing tool or interfering with microbial detection. Subsequently, it is dispensed into anaerobic bottles and aerobic bottles. When injecting into the anaerobic bottle, a sterile syringe or pipette needs to be used to quickly inject the liquid into the anaerobic bottle to avoid exposure to oxygen and ensure an anaerobic environment inside the bottle.

[0037] However, when operating with a sterile syringe or pipette, it relies on manual operation. Manual operation may introduce oxygen when injecting the oscillating liquid into the anaerobic bottle, which may have a direct toxicity to anaerobic microorganisms, thereby interfering with the culture results and misleading etiological analysis, and unable to guide clinical medication.

[0038] Therefore, this ultrasonic oscillation automatic sampler includes a housing 1. Inside the housing 1, there is a sampling door 11. By opening the sampling door 11, the anaerobic bottle 3 and the aerobic bottle 31 can be placed in the sampling area. Inside the housing 1, there is a rotating disk 12, which can rotate relative to the housing 1. Inside the housing 1, there are an anaerobic sampling assembly 28 and an aerobic sampling assembly 29. Both the anaerobic sampling assembly 28 and the aerobic sampling assembly 29 are connected to the rotating disk 12. When the rotating disk 12 rotates, the anaerobic sampling assembly 28 can discharge the oscillating liquid into the anaerobic bottle 3. Since the anaerobic bottle 3 is filled with nitrogen to maintain an anaerobic environment before the oscillating liquid enters, when the oscillating liquid enters the anaerobic bottle 3, the nitrogen in the anaerobic bottle 3 is compressed and discharged into the storage bottle 32. 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, so as to ensure that the nitrogen entering the storage bottle 32 is nitrogen. When the nitrogen in the storage bottle 32 reaches the first upper limit, the nitrogen stops discharging into the storage bottle 32. The remaining gas may be mixed with oxygen or other gases, so the remaining gas in the anaerobic bottle 3 is discharged through the anaerobic sampling assembly 28. After the discharge of the remaining gas in the anaerobic bottle 3 is completed, the storage bottle 32 discharges the nitrogen into the anaerobic bottle 3 again, ensuring that the anaerobic bottle 3 remains in an anaerobic environment. The aerobic sampling assembly 29 can discharge the oscillating liquid into the aerobic bottle 31.

[0039] Regarding the rotating disk 12, the rotating disk 12 can be limited by the support frame 14 so that the rotating disk 12 can only rotate. The rotating disk 12 can be a gear, and other gears mesh with the teeth on the rotating disk 12 to drive the rotation of the rotating disk 12. The rotating disk 12 can also be a pulley, and other pulleys and belts drive the rotation of the rotating disk 12. In other embodiments of the present invention, it can be replaced with other structures as long as it can ensure that the rotating disk 12 can rotate.

[0040] The sampling assembly 2 includes an anaerobic sampling assembly 28 and an aerobic sampling assembly 29, and the specific structures of the anaerobic sampling assembly 28 and the aerobic sampling assembly 29 are the same. The anaerobic sampling assembly 28 and the aerobic sampling assembly 29 only have different connecting pipelines.

[0041] The anaerobic sampling assembly 28 is connected to a first pipeline 4 and a second pipeline 5. The oscillating liquid is sucked into the anaerobic sampling assembly 28 through the first pipeline 4. The anaerobic sampling assembly 28 is connected to the anaerobic bottle 3 through the second pipeline 5 to discharge the oscillating liquid into the anaerobic bottle 3. A third pipeline 6 is connected to the anaerobic bottle 3. The anaerobic bottle 3 is connected to the storage bottle 32 through the third pipeline 6 to discharge the nitrogen gas in the anaerobic bottle 3 into the storage bottle 32. A fourth pipeline 7 is connected to the first pipeline 4 and the third pipeline 6. When the nitrogen gas in the storage bottle 32 reaches the first upper limit, the gas in the anaerobic bottle 3 is discharged into the anaerobic sampling assembly 28 through the fourth pipeline 7. A fifth pipeline 8 is connected to the second pipeline 5. The gas in the anaerobic sampling assembly 28 is discharged through the fifth pipeline 8.

[0042] 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. The first switching valve 43 has a first communication state and a second communication state;

[0043] 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 suck the oscillating liquid into the anaerobic sampling assembly 28;

[0044] When the first switching valve 43 is in the second communication state, the fourth pipeline 7 is connected to the second connecting pipe 42 through the first switching valve 43 so that when the nitrogen gas in the storage bottle 32 reaches the first upper limit, the gas in the anaerobic bottle 3 is discharged into the anaerobic sampling assembly 28.

[0045] 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 has a third communication state and a fourth communication state;

[0046] When the second switching valve 53 is in the third communication 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;

[0047] 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.

[0048] 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 has a fifth communication state and a sixth communication state;

[0049] 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 gas in the anaerobic bottle 3 into the storage bottle 32;

[0050] 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.

[0051] This sampler further includes a sixth pipeline 9. The storage bottle 32 is connected to the anaerobic bottle 3 through the sixth pipeline 9. A communication valve 91 is provided at the connection between the sixth pipeline 9 and the storage bottle 32. Whether the storage bottle 32 and the anaerobic bottle 3 are connected through the sixth pipeline 9 is controlled by the opening and closing of the communication valve 91. After the gas in the anaerobic bottle 3 is discharged, the communication valve 91 is activated, and the storage bottle 32 discharges nitrogen gas into the anaerobic bottle 3 through the sixth pipeline 9.

[0052] Refer to Figure 6, first, the first switching valve 43 is in the first communication state, so that the first connecting pipe 41 is communicated with the second connecting pipe 42 through the first switching valve 43 to suck the oscillating liquid into the anaerobic sampling assembly 28. The second switching valve 53 is in the third communication state, and the third connecting pipe 51 is communicated with the fourth connecting pipe 52 through the second switching valve 53. The oscillating 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. Since the anaerobic bottle 3 is filled with sufficient nitrogen to maintain an anaerobic environment before the oscillating liquid enters, when the oscillating liquid enters the anaerobic bottle 3, the nitrogen in the anaerobic bottle 3 is pressed into the storage bottle 32. 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, so as to ensure that the nitrogen entering the storage bottle 32 is nitrogen.

[0053] Refer to Figure 7 , 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. 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. Therefore, the anaerobic sampling assembly 28 passes through the second connecting pipe 42, the fourth pipeline 7 and the fifth connecting pipe 61 to discharge the remaining gas in the anaerobic bottle 3. The remaining gas may be mixed with oxygen or other gases. Subsequently, after the remaining gas in the anaerobic bottle 3 is discharged through the anaerobic sampling assembly 28, the third connecting pipe 51 and the fifth pipeline 8, the anaerobic sampling assembly 28 stops operating, and the communication 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 inside of the anaerobic bottle 3 is in a negative pressure state, so as to suck the ammonia gas in the storage bottle 32 into the anaerobic bottle 3, ensuring that the anaerobic bottle 3 is kept in an anaerobic environment and ensuring the accuracy of the culture result to correctly guide clinical medication.

[0054] The aerobic sampling assembly 29 is connected with a seventh pipeline 33 and an eighth pipeline 34. 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.

[0055] 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 the 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.

[0056] Preferably, one-way valves are provided in 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.

[0057] The sampling assembly 2 includes a sampling bottle 21. A sealing plug 22 is slidably connected in the sampling bottle 21. A piston rod 23 is hinged to the sealing plug 22. A first collar 24 is fixedly connected to the piston rod 23. The first collar 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 reciprocally slides along the sampling bottle 21.

[0058] When the sealing plug 22 slides upward along the sampling bottle 21, a 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 pipe 41 and the second connecting pipe 42, or the remaining gas in the anaerobic bottle 3 is sucked into the sampling bottle 21 through the second connecting pipe 42, the fourth pipeline 7, and the fifth connecting pipe 61. When the sealing plug 22 slides downward along the sampling bottle 21, a 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 pipe 51 and the fourth connecting pipe 52, or the remaining gas in the anaerobic bottle 3 is discharged through the third connecting pipe 51 and the fifth pipeline 8.

[0059] A chute 13 is formed in the rotating disk 12. The connecting rod 25 is slidably connected to the chute 13. A cylinder 26 is fixedly connected to the rotating disk 12. An output end of the cylinder 26 is fixedly connected to a second collar 27. The second collar 27 is sleeved on the connecting rod 25. The displacement of the connecting rod 25 along the chute 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 sliding stroke of the piston rod 23 driving the sealing plug 22 along the sampling bottle 21 decreases, so that the discharge amount of the oscillating liquid decreases, facilitating manual control of the amount of the oscillating liquid required for the anaerobic bottle 3 and the aerobic bottle 31, and the discharge amount of the gas also decreases. When the cylinder 26 drives the connecting rod 25 to move away from the center of the rotating disk 12, the sliding stroke of the piston rod 23 driving the sealing plug 22 along the sampling bottle 21 increases, so that the discharge amount of the oscillating liquid increases, facilitating manual control of the amount of the oscillating liquid required for the anaerobic bottle 3 and the aerobic bottle 31, and the discharge amount of the gas also increases.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. 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 claims of the present invention.
