Description

Technical Field

[0001] The invention relates to the technical field of medical detection, in particular to a separation and sampling device for medical detection. Background Art

[0002] Medical testing is a science that conducts microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology and other tests on materials taken from the human body, thereby providing information for the prevention, diagnosis, treatment of human diseases and the assessment of human health. Some medical test items require the collection of microorganisms or cells to be cultivated in the culture medium in the culture cup. After the cultivation, the culture medium is sampled and tested during the medical test.

[0003] At present, in order to prevent leakage or splashing when pouring the culture fluid into the culture cup, a sampling device is needed to extract the fluid for sampling. When sampling, the sealing film on the culture cup needs to be manually torn off first, and then the pipette head of the sampling device is placed in the culture cup. The culture fluid inside the culture cup is sucked into each test tube through the sampling pump, and then the samples in the multiple test tubes are tested by the instrument. Since the culture fluid in the culture cup will be stratified during the long-term cultivation process, the concentration of the culture fluid in the upper and lower layers of the culture cup is different. Since the height at which the pipette head of the sampling pump is lowered into the culture cup is fixed, the sample concentration is prone to unevenness during the sampling process of the culture fluid, which makes the test result prone to deviation and affects the test result.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the medical detection separation sampling device, the culture cup can be placed through the placement seat arranged in the sampling seat, and the servo motor can drive the first rotating rod to rotate forward and reversely, so that the placement seat and the culture cup can rotate synchronously, so that the culture solution inside the culture cup can be mixed by force, and the uniformity of the concentration of the culture solution can be improved. When sampling, the concentration difference of the culture solution can be reduced, and the accuracy of the detection is improved. Through the multiple clamping components arranged on the placement seat, the culture cup can be conveniently clamped and fixed in the placement seat, so that the position deviation and collision with the placement seat can be avoided during the rotation of the culture cup, and the protection performance is improved. The electric push rod fixed on the sampling seat can be By adjusting the height of the mounting plate and the first interference rod, the filter head in the sampling assembly can be inserted into the culture cup, and the culture fluid can be conveniently extracted through the sampling pump, and the sampled culture fluid can be flowed into the detection test tube for testing. When the filter head is used, the culture material and the liquid in the culture fluid can be separated and sampled to avoid clogging of the pipeline by the culture material. When the first interference rod moves downward, it can interfere with the first interference frame, causing the first interference frame to move horizontally and interfere with the interference ring. The upward movement of the interference ring can achieve the purpose of synchronous interference with several clamping assemblies, causing the clamping assembly to automatically clamp the culture cup. At the same time, the placement seat will not hinder the work of the clamping assembly when it rotates.

[0018] 2. In this medical detection separation and sampling device, a sealing film is provided on the culture cup, which can isolate microorganisms, effectively prevent the intrusion of microorganisms such as bacteria and fungi, and maintain the safety of the culture environment. At the same time, during the rotation of the culture cup, liquid spillage can be avoided. Through the second contact piece fixed on the first contact frame, when the first contact frame moves, the second contact piece contacts the rocker bracket, prompting the rocker bracket to deflect and contact the sixth contact wedge fixed to one end of the first rack, so as to achieve the purpose of driving the second rotating rod fixed on the first gear by the first rack, making the hollow rod drive the hollow seat to automatically approach the sealing film. The sealing piece provided at the opening can reduce the contact between the blade and the air, reduce the attachment of bacteria, and improve the sampling effect. At the same time, the ultraviolet disinfection lamp fixed in the hollow seat can achieve the purpose of disinfecting and sterilizing the blade. When the cutter bar arranged in the hollow seat moves, it can drive the blade to vertically penetrate the hollow seat and contact the sealing film, facilitating the cutting of the sealing film for the next step of processing. When the second contact frame slidably connected to the hollow seat deflects, it can contact the arc-shaped block, prompting the second contact frame to slide within the hollow seat, so as to achieve the purpose of driving the U-shaped contact block and the first contact piece to move synchronously by the second contact frame, making the U-shaped contact block contact the second contact wedge, facilitating the automatic opening of the opening by the movement of the sealing piece and the extension of the blade for work. At the same time, during the movement of the first contact piece, it can contact the second contact rod, prompting the second contact rod to contact the fifth contact wedge fixed to the upper end of the cutter bar during its movement, so as to achieve the purpose of driving the blade to automatically extend from the opening for film cutting treatment.

[0019] 3. In the medical detection separation sampling device, when the first resistance rod continues to move downward, it collides with the fourth resistance wedge through the round rod, prompting the second rack to move horizontally so that the second gear drives the third rotating rod, the rectangular rod and the strip plate to rotate synchronously. The fourth resistance rod fixed under the strip plate can collide with one of the arc-shaped protrusions during the rotation process, so that the film stripping head can automatically move from the incision of the sealing film to the inside of the culture cup. Through the cooperation of the film stripping head and the film rod, the sealing film is stripped from the culture cup during the rotation process, so that the filter head can smoothly enter the culture cup for sampling. When another arc-shaped protrusion conflicts with the fourth resistance rod, the film stripping head can bring the stripped sealing film into the culture cup. When the film is removed from the inside of the culture cup, the third resistance frame arranged in the film stripping head can drive the conical resistance block to resist several film stripping rods equidistantly distributed on the circumference at the same time, so as to make the film stripping rod extend and improve the film stripping effect; when the strip plate rotates and approaches the fourth resistance wedge block, the third resistance rod can resist the fourth resistance wedge block, so that the third resistance rod pushes the third resistance strip to move horizontally and resist the third resistance frame, thereby raising the height of the third resistance frame, making it convenient to release the resistance of the conical resistance block to the film stripping rod, so that the film stripping rod can automatically retract into the film stripping head, so as to achieve the purpose that the removed sealing film can be automatically detached from the film stripping head, so as to facilitate the recycling of the sealing film.

[0033] When sampling, refer to Figure 1-Figure 2First, place the culture cup 5 containing the culture solution in the placement seat 4 in the sampling seat 1, and at the same time, the electric push rod 10 drives the mounting plate 11 to move downward, so that the first contact rod 14 contacts the first contact frame 12, prompting the first contact frame 12 to move horizontally and contact the contact ring 8, and the second spring 13 accumulates force. The contact ring 8 is affected by the resistance force and moves vertically on the first sliding frame 7. The first spring 9 accumulates force. The contact ring 8 can contact the first contact wedge 43 of the clamping assembly during the movement, so that the first contact wedge 43 can drive the sliding rod 41 and one end of the sliding rod 41 to be fixed.

[0036] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 7, a sealing film 15 is provided on the culture cup 5. One side of the sampling seat 1 is rotatably connected to a second rotating rod 16. A first gear 17 is fixed on the second rotating rod 16. A first rack 18 is engaged with one side of the first gear 17. A seesaw component for adjusting the moving position of the first rack 18 is provided on the sampling seat 1. The upper end of the second rotating rod 16 is fixed with a hollow rod 19. One end of the hollow rod 19 is fixed with a hollow seat 20. A cutter bar 21 is slidably connected in the hollow seat 20. A blade 22 is fixed to the lower end of the cutter bar 21. And a fifth abutting wedge 211 is fixed to the upper end of the cutter bar 21.

A U-shaped abutting block 33 that abuts against the second abutting wedge 28 is fixed to one end of the second abutting frame 31. A first abutting piece 34 that abuts against the second abutting rod 29 is fixed to the second abutting frame 31. An arc-shaped block 35 that abuts against one end of the second abutting frame 31 is fixed on the sampling seat 1.

[0039] The seesaw component includes a mounting strip 181. A seesaw bracket 182 is rotatably connected to the mounting strip 181. A torsion spring 183 is connected between the seesaw bracket 182 and the mounting strip 181. A second abutting piece 184 that abuts against the seesaw bracket 182 is fixed on the first abutting frame 12. A sixth abutting wedge 185 that abuts against the seesaw bracket 182 is fixed to one end of the first rack 18. A second sliding bracket 186 is fixed on the sampling seat 1. The second sliding bracket 186 is elastically connected to the first rack 18 through an eighth spring 187.

[0040] In order to isolate microorganisms, effectively prevent the intrusion of microorganisms such as bacteria and fungi, and maintain the safety of the culture environment, a sealing film 15 is provided on the culture cup 5. At the same time, liquid overflow can be avoided during the rotation of the culture cup 5. The presence of the sealing film 15 will affect the sampling effect, and the sealing film 15 needs to be cut. Refer to Figure 1-Figure 5, the second abutting piece 184 fixed on the first abutting frame 12 can move synchronously with the first abutting frame 12. During the movement of the second abutting piece 184, it can abut against the rocker bracket 182 in the rocker assembly, prompting the rocker bracket 182 to rotate on the mounting strip 181, and the torsion spring 183 to store energy. When the upper end of the rocker bracket 182 rotates, it can push the sixth abutting wedge 185 to move horizontally, prompting the sixth abutting wedge 185 to drive the first rack 18 to slide on the second sliding bracket 186, and the eighth spring 187 to store energy. The sliding first rack 18 can drive the meshing first gear 17 to rotate, prompting the second rotating rod 16 to drive the hollow rod 19 and the hollow seat 20 fixed at one end of the hollow rod 19 to rotate, gradually approaching the upper part of the sealing film 15;

[0041] At the same time, the second abutting frame 31 slidably connected in the hollow rod 19 can abut against the arc-shaped block 35 during the rotation process, prompting the second abutting frame 31 to move horizontally in the hollow rod 19, and the seventh spring 32 to store energy. It can push the U-shaped abutting block 33 to abut against the second abutting wedge 28, prompting the two sealing pieces 25 to slide synchronously on the sliding rod 26, and the fifth spring 27 to store energy, so as to achieve the purpose of opening the opening 24. At the same time, the first abutting piece 34 fixed on the second abutting frame 31 abuts against the second abutting rod 29, which can drive the second abutting rod 29 to slide on the hollow seat 20, so as to achieve the purpose of the second abutting rod 29 abutting against the fifth abutting wedge 211, prompting the cutter bar 21 to drive the blade 22 to penetrate downward through the opening 24, and the fourth spring 23 to store energy, so that the blade 22 moves downward to cut the sealing film 15. As the second rotating rod 16 rotates, the blade 22 rotates in an arc on the sealing film 15 to form an arc-shaped cut, which is convenient for the next step of processing. When the second abutting frame 31 is disengaged from the arc-shaped block 35, the blade 22 retracts into the hollow seat 20;

[0042] Combined with Figure 4 and Figure 5 , one end of the two sealing pieces 25 is slidably connected to the sliding rod 26, and the other end is fixedly connected to the two symmetrically arranged second abutting wedges 28. In the initial state, the two sealing pieces 25 are in contact. The two side ends of the U-shaped abutting block 33 respectively abut against the abutting surfaces of the two second abutting wedges 28. When the U-shaped abutting block 33 moves and abuts against the inclined surfaces of the two second abutting wedges 28, it can push the two second abutting wedges 28 to move in opposite directions horizontally, so as to achieve the purpose of the two sealing pieces 25 sliding in opposite directions on the sliding rod 26, thereby prompting the opening 24 to be able to open.

[0043] Combined with Figure 3When the first gear 17 rotates, the second rotating rod 16 can be driven to rotate synchronously, and the second contact frame 31 slidably connected to the hollow rod 19 also rotates. During the rotation process, the second contact frame 31 contacts one end of the arc block 35. After the contact, the second contact frame 31 can slide in the hollow rod 19. On the one hand, the two sealing pieces 25 can move in opposite directions on the sliding rod 26 to open the opening 24. On the other hand, the second contact rod 29 can contact the fifth contact wedge 211, so that the knife rod 21 drives the blade 2 2 downwardly penetrates the opening 24. When the first gear 17 stops rotating, the hollow rod 19 and one end of the second abutting frame 31 are already located on one side of the other end of the arc block 35. At this time, the second abutting frame 31 and the arc block 35 are in a state of releasing mutual abutment. The seventh spring 32 releases its elastic force, prompting the second abutting frame 31 to move toward the outside of the hollow rod 19. At this time, the second abutting rod 29 and the fifth abutting wedge 211 are released from abutment. The knife rod 21 drives the blade 22 to retract into the hollow seat 20 to complete the reset. The two sealing pieces 25 move toward each other on the slide bar 26 to complete the reset.

[0044] The ultraviolet disinfection lamp 36 can be used to disinfect and sterilize the blade 22 inside the hollow seat 20, thereby preventing bacteria from growing on the blade 22.

[0045] The second abutment frame 31 is mainly composed of a round rod and a conical wedge. When the conical wedge is abutted, it can drive the round rod to move horizontally in the hollow seat 20.
