Description

Technical Field

[0001] The present application relates to the technical field of sample collection, and particularly to a sampling device and an analyzer. Background Art

[0002] The main functional components of the sampling device on a blood sample analysis instrument are a sampling needle and a cleaning swab. The sampling needle will move in the vertical and horizontal directions driven by a driving component. During the movement of the sampling needle, the sampling needle is always inserted into the cleaning swab, and the cleaning swab cleans the sampling needle under the action of negative pressure. Due to processing and assembly error problems in the existing sampling device, it is difficult to ensure the concentric fixation of the sampling needle and the cleaning swab. Therefore, a floating cleaning swab is mostly used.

[0003] Since the outside of the cleaning swab is connected to a pipeline, the pipeline may pull the cleaning swab to cause deviation or inclination. Furthermore, the deviated cleaning swab will affect the moving accuracy of the sampling needle inserted therein, further affecting the sampling performance of the sampling device. And during the process of the cleaning swab cleaning the sampling needle, the floating cleaning swab is prone to uncontrollable vibration or deviation under the action of negative pressure and the pipeline. The positions of the cleaning swab and the sampling needle are uncontrollable, and liquid leakage or incomplete cleaning is likely to occur. Utility Model Content

[0036] The following will describe the solutions of the embodiments of the present application in detail with reference to the drawings in the specification.

[0037] In the following description, specific details such as specific system structures, interfaces, and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the present application.

[0040] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the first embodiment of the sampling device of the present application. The sampling device 1 provided by the embodiments of the present application includes a frame 11, a sampling needle 12, a swab fixing plate 13, and a cleaning swab 14.

[0041] Among them, the sampling needle 12 is arranged on the frame 11, and the sampling needle 12 is arranged to move relative to the frame 11; the swab fixing plate 13 is arranged on the frame 11, the cleaning swab 14 is fixedly arranged on the swab fixing plate 13, and the swab fixing plate 13 fixes the cleaning swab 14 to avoid the floating of the cleaning swab 14. The sampling needle 12 passes through the cleaning swab 14, the sampling needle 12 is arranged to slide relative to the cleaning swab, and the sampling needle 12 and the cleaning swab 14 are concentrically arranged. When the sampling needle 12 slides relative to the cleaning swab 14, the cleaning swab 14 can clean the sampling needle 12.

[0042] Among them, since the sampling needle 12 passes through the cleaning swab 14 and is concentrically arranged with the cleaning swab 14, and the sampling needle 12 and the swab fixing plate 13 are fixed on the same frame, it can be realized that when the sampling needle 12 moves relative to the frame 11 and slides relative to the cleaning swab 14, the sampling needle 12 always maintains a concentric arrangement with the cleaning swab 14, improving the safety and accuracy of the sampling needle 12 during movement.

[0043] Specifically, since the cleaning swab 14 is fixed on the swab fixing plate 13, the cleaning swab 14 and the sampling needle 12 passing through the cleaning swab 14 will not be deformed by the environment and working conditions, and the pipelines connected to the cleaning swab 14 cannot pull the cleaning swab 14 to cause the deviation of the cleaning swab 14. The installation states of the pipelines in different sampling devices 1 will not affect the consistency between different component structures. Moreover, since the swab fixing plate 13 and the sampling needle 12 are arranged on the same frame 11, it can be ensured that the positions of the cleaning swab 14 and the sampling needle 12 can maintain a high degree of consistency, avoiding the occurrence of liquid leakage or unclean cleaning caused by the uncontrollable positions of the cleaning swab 14 and the sampling needle 12, improving the cleaning efficiency of the cleaning swab 14 for the sampling needle 12, and improving the safety of the sampling device 1.

[0044] Currently, in the prior art, the external connection pipelines of the swab will pull the swab to cause deviation or inclination, and the pipelines installed manually cannot ensure the installation consistency between different components; or, the difference in the processing of the sampling needle 12 causes a part of the outside of the sampling needle 12 to protrude, which will also cause the swab to deviate or incline. Therefore, there are certain differences in the positions and inclination degrees of the swabs between different components, and the position of the swab is uncontrollable.

[0045] Furthermore, if the swab is not fixed and can float freely, and after the swab is deflected by the environment or the pipeline, when the middle area of ​​the sampling needle 12 with smaller rigidity slides into the deflected swab, it can be easily driven by the swab to produce irreversible deflection and deformation, so that the position of the needle tip of the sampling needle 12 before and after the movement is not in the same vertical direction, which will cause the puncture, sample aspiration or sample splitting position of the needle tip of the sampling needle 12 at different heights to deviate from the preset position, affecting the performance of the sampling device 1.

[0046] The sampling device 1 of the present application is provided with a swab fixing plate 13 to fix the cleaning swab 14, thereby avoiding the impact caused by the free floating of the cleaning swab 14 in the prior art, improving the safety and movement accuracy of the sampling needle 12, ensuring the operating performance of the sampling device 1, and enhancing the user's experience of the sampling device 1.

[0047] Optionally, see Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the partial structure of the cleaning swab and the swab fixing plate is shown in FIG. A first through hole 131 is provided at the first end of the swab fixing plate 13, and a fixing member 141 is provided at one end of the cleaning swab 14. The fixing member 141 can be interference-fitted with the first through hole 131 to set the cleaning swab 14 on the swab fixing plate 13.

[0048] In another embodiment, if Figure 2 As shown, the swab fixing plate 13 may further include screws 132 , and the screws 132 further fix the cleaning swab 14 on the swab fixing plate 13 .

[0049] In other embodiments, other fixing structures may also be used to fix the cleaning swab 14 and the swab fixing plate 13, and the present application does not limit this.

[0050] Optionally, the projection of the sampling needle 12 on the swab fixing plate 13 overlaps with the center of the first through hole 131; a second through hole 142 is provided at the center of the fixing member 141, the second through hole 142 passes through the cleaning swab 14, and the sampling needle 12 is inserted into the cleaning swab 14 through the second through hole 142; the axis of the first through hole 131 and the axis of the second through hole 142 are colinearly arranged.

[0051] Specifically, since the second through-hole 142 is provided at the center of the fixing member 141, and the fixing member 141 is in interference fit with the first through-hole 131, the cleaning swab 14 is disposed on the swab fixing plate 13 through the cooperation of the fixing member 141 and the first through-hole 131. Therefore, when the cleaning swab 14 is fixed on the swab fixing plate 13, the second through-hole 142 is located at the center of the first through-hole 131. Further, the projection of the sampling needle 12 on the swab fixing plate 13 overlaps with the center of the first through-hole 131, and the axis of the first through-hole 131 is collinear with the axis of the second through-hole 142. That is, when the cleaning swab 14 is disposed on the swab fixing plate 13 and the sampling needle 12 penetrates through the cleaning swab 14, the sampling needle 12 is concentric with the second through-hole 142.

[0052] Moreover, the cleaning swab 14 is fixed on the swab fixing plate 13, ensuring that during the sliding process of the sampling needle 12, the cleaning swab 14 is fixed, and the sampling needle 12 and the second through-hole 142 are always concentric, improving the safety and sliding accuracy of the sampling needle 12 during the sliding process.

[0053] In the prior art, if the cleaning swab 14 is not fixed, the cleaning swab 14 will be inclined due to the pulling of the pipeline. During the sliding process of the sampling needle 12, the second through-hole 142 is not concentric with the sampling needle 12. Then, during the sliding process of the sampling needle 12, the sampling needle 12 will cause friction on the hole wall of the second through-hole 142, and the long-term friction will cause wear on the hole wall of the cleaning swab 14 and the outer wall of the sampling needle 12. Moreover, since the cleaning swab 14 is not fixed, the position of each friction between the sampling needle 12 and the cleaning swab 14 is uncontrollable, that is, the wear on the sampling needle 12 and the cleaning swab 14 is uncontrollable.

[0054] In the embodiment of the present application, by fixing the cleaning swab 14 and ensuring that the sampling needle 12 is always concentric with the center of the second through-hole 142 during the sliding process, the safety of the sampling needle 12 during the sliding process is improved, the safety of the sampling device 1 is improved, and the performance of the sampling device 1 is ensured.

[0055] Optionally, please continue to refer to Figure 1 , the sampling device 1 further includes a guide rail assembly 15 and a transmission assembly 16, and the guide rail assembly 15 and the transmission assembly 16 are arranged on the frame 11 at intervals.

[0056] Among them, the guide rail assembly 15 includes a sliding guide rail 151 and a slider 152. The sliding guide rail 151 is arranged on the frame 11 along the gravity direction, the slider 152 is slidably arranged on the sliding guide rail 151, the sampling needle 12 is arranged on the slider 152, and the swab fixing plate 13 is arranged at one end of the sliding guide rail 151;

[0057] The transmission assembly 16 includes a transmission wheel 161 and a conveyor belt 162. The transmission wheel 161 is arranged on the frame 11, the conveyor belt 162 is wound around two transmission wheels 161, and one end of the slider 152 is arranged on the conveyor belt 162.

[0058] Moreover, in the direction of gravity, the swab fixing plate 13 and the cleaning swab 14 are arranged below the slider 152.

[0059] Specifically, the transmission assembly 16 may include two transmission wheels 161. The line segment connecting the two transmission wheels 161 is parallel to the extending direction of the sliding guide rail 151. That is, one belt segment of the conveyor belt 162 is parallel to the extending direction of the sliding guide rail 151, and the slider 152 is arranged on this belt segment. Then, under the driving action of the transmission wheel 161 and the conveyor belt 162, the slider 152 is driven to slide on the sliding guide rail 151 in the direction of gravity or the opposite direction of the gravity direction. In other embodiments, the transmission assembly 16 may also include other numbers of transmission wheels 161, such as three, etc. On the basis of realizing that there is a belt segment of the conveyor belt 162 parallel to the extending direction of the sliding guide rail 151, the specific number of the transmission wheels 161 is not limited in this application.

[0060] When the sampling needle 12 in the sampling device 1 needs to move in the direction of gravity or the opposite direction of the gravity direction for operations such as puncturing, sampling, and sub-sampling, the transmission wheel 161 of the transmission assembly 16 rotates to drive the conveyor belt 162 to transmit. Since one end of the slider 152 is arranged on the conveyor belt 162, when the conveyor belt 162 is transmitting, the slider 152 will slide on the sliding guide rail 151 following the transmission of the conveyor belt 162. Then, the slider 152 can drive the sampling needle 12 to move downward in the direction of gravity or upward in the opposite direction of the gravity direction, so that the sampling needle 12 can perform operations such as puncturing, sampling, and sub-sampling. And since the swab fixing plate 13 is arranged at one end of the sliding guide rail 151, and in the direction of gravity, the swab fixing plate 13 and the cleaning swab 14 are arranged below the slider 152. Therefore, when the slider 152 drives the sampling needle 12 to move up and down, the sampling needle 12 can slide through the cleaning swab 14, and the cleaning swab 14 can clean the sampling needle 12, improving the efficiency of the sampling device 1.

[0061] Optionally, a card slot (not shown in the figure) is provided on the slider 152. The card slot extends along the direction of gravity, and the sampling needle 12 is arranged in the card slot.

[0062] The sampling device 1 further includes a sampling needle pressing plate 17. The sampling needle pressing plate 17 is detachably arranged on the first surface of the slider 152 and covers the card slot to fix the sampling needle 12 in the card slot, wherein the first surface of the slider 152 is set as the surface of the slider 152 where the card slot is provided.

[0063] During the actual installation process, the user can first place one end of the sampling needle 12, which is far from the needle tip (used for puncturing and collecting samples, etc.), in the card slot, and then set the sampling needle pressing plate 17 on the first surface of the slider 152. Since the sampling needle pressing plate 17 covers the card slot, that is, the sampling needle pressing plate 17 will fix the sampling needle 12 in the card slot, improving the stability and safety of the sampling needle 12 set on the slider 152 and avoiding the situation where the sampling needle 12 falls off the slider 152.

[0064] In one embodiment, since one end of the sampling needle 12 far from the needle tip needs to be connected to a pipeline, therefore, the connection part between the sampling needle 12 and the pipeline can be further placed in the card slot to fix the connection part between the sampling needle 12 and the pipeline, improving the stability of the connection between the sampling needle 12 and the pipeline and avoiding the situation where the pipeline is pulled away from the sampling needle 12 when the sampling needle 12 moves up and down.

[0065] In another embodiment, the sampling needle pressing plate 17 can be detachably set on the slider 152 by screws. In other embodiments, the sampling needle pressing plate 17 can also be installed by other detachable structures, and this application does not limit this.

[0066] Through the detachable setting of the sampling needle pressing plate 17, when the sampling needle 12 needs to be replaced in the sampling device 1, the user can separate the sampling needle pressing plate 17 from the slider 152 to replace the sampling needle 12, and after the sampling needle 12 is replaced, reinstall the sampling needle pressing plate 17 on the slider 152, improving the convenience of replacing the sampling needle 12 and enhancing the user experience of using the sampling device 1.

[0067] Optionally, the frame 11 includes a first support plate 111 and a second support plate 112. The second support plate 112 is vertically arranged at the edge of the first support plate 111, and the first support plate 111 and the second support plate 112 form an L shape.

[0068] Please combine Figure 1 and Figure 3 , Figure 3 is a schematic structural diagram of the second embodiment of the sampling device of this application. The transmission component 16 is arranged on the first surface of the first support plate 111, and the first surface of the first support plate 111 is the surface where the second support plate 112 is connected to the first support plate 111.

[0069] And as Figure 1 and Figure 4 shown, Figure 4It is a schematic structural diagram of the third embodiment of the sampling device of the present application. The guide rail assembly 15 is arranged on the first surface of the second support plate 112. The first surface of the second support plate 112 is the surface of the second support plate 112 close to the second end of the first support plate 111. The first end and the second end of the first support plate 111 are two opposite ends on the first support plate 111.

[0070] Specifically, please continue to refer to Figure 1 , the first support plate 111 and the second support plate 112 form an L shape to form an accommodating space. Furthermore, the guide rail assembly 15 and the transmission assembly 16 are respectively arranged in the accommodating space, and the guide rail assembly 15 is arranged on the second support plate 112, and the transmission assembly 16 is arranged on the first support plate 111. While the transmission assembly 16 drives the slider 152 in the guide rail assembly 15 to slide on the sliding guide rail 151, the volume of the frame 11 is reduced, the occupied space of the sampling device 1 is reduced, and the user experience of using the sampling device 1 is improved.

[0071] In one embodiment, the transmission assembly 16 may further include a driving motor 163. The driving motor 163 is arranged on the second surface of the first support plate 111. Among them, the second surface and the first surface of the first support plate 111 are two opposite surfaces on the first support plate 111, and the rotating shaft of the driving motor 163 is connected to one of the two transmission wheels 161.

[0072] Among them, the rotating shaft of the driving motor 163 is connected to the transmission wheel 161 to drive the transmission wheel 161 to rotate, and then drive the conveyor belt 162 to drive, realizing the transmission function of the transmission assembly 16. As described above, the transmission assembly 16 may include two transmission wheels 161, so the driving motor 163 is connected to any one of the two transmission wheels 161.

[0073] Specifically, the transmission wheel 161 connected to the driving motor 163 may be defined as the main transmission wheel, and the transmission wheel 161 not connected to the driving motor 163 may be defined as the auxiliary transmission wheel. When the sampling needle 12 needs to move, the driving motor 163 is started, the rotating shaft of the driving motor 163 drives the main and driven wheels to rotate, and then the main and driven wheels drive the conveyor belt 162 to drive, and the conveyor belt 162 drives the auxiliary transmission wheel to rotate, realizing the operation of the transmission assembly 16. Furthermore, the conveyor belt 162 drives the sliding of the slider 152 to realize the movement of the sampling needle 12.

[0074] Moreover, by arranging the driving motor 163 on the second surface of the first support plate 111, the occupied area of the transmission assembly 16 arranged on the first support plate 111 is reduced, the area of the first support plate 111 is reduced, and the volume of the frame 11 is further reduced.

[0075] Optionally, please continue to refer toFigure 2 The sampling device 1 further includes a baffle 18 which is arranged at the first end of the swab fixing plate 13 to form a groove 181 on the surface of the swab fixing plate 13 close to the slider 152.

[0076] Wherein, at one end of the swab fixing plate 13 away from the slider 152, the sampling needle 12 punctures and samples the sample tube or sub-samples the detection pool. At this time, the opening of the reaction pool or the detection pool is not sealed. Since the sampling device 1 is in a non-sealed environment (it will come into contact with dust in the environment), dust in the environment may adhere to the guide rail assembly 15 and the transmission assembly 16. During the sliding process of the slider 152, dust in the environment or debris of the guide rail assembly 15 and the transmission assembly 16 itself may fall due to the action of gravity and fall into the sample tube or the detection pool, contaminating the sample and affecting the detection efficiency of the sample. Therefore, in the embodiment of the present application, it is proposed to arrange a baffle 18 at the first end of the swab fixing plate 13. The baffle 18 forms a groove 181 on the surface of the swab fixing plate 13 close to the slider 152 to collect dust, debris, etc. falling from the guide rail assembly 15 or the transmission assembly 16, avoiding the contamination of the sample by dust and debris, and further improving the safety of the sampling device 1.

[0077] In addition, after the sampling needle 12 inserted into the cleaning swab 14 separates blood or reagent, during the movement of the sampling needle 12, the residual liquid existing at the tip of the sampling needle 12 can be scraped off by the end of the baffle 18 and dropped along the baffle 18 into the groove 181, avoiding the excess residue on the tip of the sampling needle 12 from falling into the reaction pool or the detection pool during the process of separating blood or reagent, thereby affecting the sample detection result.

[0078] In one embodiment, the baffle 18 and the swab fixing plate 13 are detachably connected. Thus, when the baffle 18 is separated from the swab fixing plate 13, the user can clean the dust, debris, etc. in the groove 181, avoiding excessive accumulation of dust, debris, etc. in the groove 181 and affecting the blocking effect of the baffle 18 on dust, debris, etc.; and it is convenient to replace the baffle 18.

[0079] Optionally, the sampling device 1 further includes a position detection component 19. The position detection component 19 is arranged on the frame 11 and is spaced from the transmission component 16 for detecting the sliding position of the slider 152.

[0080] Please refer to Figure 1 and Figure 3, the position detection component 19 can be arranged on the frame 11 and corresponds to the position of the conveyor belt 162. In one embodiment, when there are two driving wheels 161, the number of the position detection components 19 can be two. The two position detection components 19 are respectively arranged at intervals with the two driving wheels 161, and are both arranged on the side of the driving wheel 161 close to the other driving wheel 161. Furthermore, the position detection component 19 can detect the position of the slider 152 arranged on the conveyor belt 162.

[0081] For example, in the defined gravity direction, the driving wheel 161 located above is defined as the first driving wheel, and the driving wheel 161 located below is defined as the second driving wheel. When the slider 152 is on the conveyor belt 162 and close to the first driving wheel, it can be considered that the sampling needle 12 is in the initial state and no operation is performed at this time; when the slider 152 is close to the second driving wheel, it can be considered that the sampling needle 12 is moving downward at this time to perform operations such as puncture.

[0082] When the position detection component 19 close to the first driving wheel detects that the slider 152 is close to the first driving wheel, it can be determined that the slider 152 drives the sampling needle 12 to return to the initial state in place at this time, and the drive motor 163 stops driving the driving wheel 161 to rotate, so as to avoid excessive transmission of the slider 152, and the slider 152 contacts the first driving wheel, causing wear. When the position detection component 19 close to the second driving wheel detects that the slider 152 is close to the second driving wheel, it can be determined that the slider 152 drives the sampling needle 12 to move to the operation position at this time, and the drive motor 163 stops driving the driving wheel 161 to rotate, so as to avoid excessive transmission of the slider 152, and the slider 152 contacts the second driving wheel, causing wear or even falling off.

[0083] By arranging the position detection component 19 to detect the sliding position of the slider 152, the excessive sliding of the slider 152 is avoided, the safety of the transmission component 16 driving the slider 152 to slide is improved, and the safety of the sampling device 1 is improved.

[0084] In summary, in the embodiment of the present application, the cleaning swab 14 and the sampling needle 12 are jointly fixed on the same frame 11 through the swab fixing plate 13. The cleaning swab 14 and the sampling needle 12 inserted through the cleaning swab 14 will not be deformed due to environmental and working conditions. The pipelines and the like connected to the cleaning swab 14 cannot pull the cleaning swab 14, causing the cleaning swab 14 to deflect. The installation states of the pipelines in different sampling devices 1 will not affect the consistency between different component structures. Moreover, since the swab fixing plate 13 and the sampling needle 12 are arranged on the same frame 11, the positions of the cleaning swab 14 and the sampling needle 12 can be kept highly consistent, avoiding the influence brought by the free floating of the cleaning swab 14 in the prior art, improving the safety and moving accuracy of the sampling needle 12, ensuring the safety and operating performance of the sampling device 1, and enhancing the user experience of using the sampling device 1.

[0085] The present application also provides an analyzer (not shown in the figure), which includes the sampling device 1 described above and at least one detection component. The sampling device 1 and the at least one detection component are spaced apart. The sampling device 1 is used to collect a sample and distribute the sample to the at least one detection component for sample detection.

[0086] Specifically, the analyzer may further include a horizontal movement component. The horizontal movement component is spaced apart from the sampling device 1 and can move the sampling device 1 above the sample tube or above one of the at least one detection components in the direction of gravity.

[0087] The following briefly describes the process of sample detection by the analyzer:

[0088] The horizontal movement component drives the sampling device 1 to move above the sample tube. The transmission component 16 and the guide rail component 15 on the sampling device 1 cooperate to drive the sampling needle 12 to move, puncture the sample tube, and collect the sample in the sample tube. Then, the transmission component 16 and the guide rail component 15 on the sampling device 1 cooperate to drive the sampling needle 12 to move back to the initial state.

[0089] Next, the horizontal movement component drives the sampling device 1 to move above one of the at least one detection components. The transmission component 16 and the guide rail component 15 on the sampling device 1 cooperate to drive the sampling needle 12 to move. The sampling needle 12 moves to the corresponding detection component and distributes the collected sample to the detection component so that the detection component can detect the sample.

[0090] Then, the horizontal movement component can drive the sampling device 1 to move above another one of the at least one detection components to distribute the sample, or move the sampling device 1 above the sample tube to collect the sample, which can be determined based on the remaining amount of the sample in the sampling needle 12. The present application does not limit this.

[0091] The above description is only the implementation manner of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present application.
