Detailed implementation manners

[0028] The following will further describe the present application in detail with reference to the drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0029] Referring to "embodiment" in this article means that the specific features, structures or characteristics described in combination with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0030] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to specific circumstances.

[0031] With the continuous development of basic medicine and medical technology, the detection principles of sample analyzers (such as blood analyzers) have become increasingly precise and diversified, the detection technology has been continuously innovated, and the detection parameters have increased significantly. "High precision, fast speed, easy operation, and strong functions" are the strong advantages of modern blood analyzers.

[0032] For example, looking at the hematology analyzers from different manufacturers on the market, the hematology analyzers using the "nucleic acid fluorescence staining" detection principle are the mainstream and model among many blood cell brands. For example, the five-part differential hematology analyzer uses a specific nucleic acid fluorescent dye. After the cells are treated with a special hemolysin, the fluorescent dye can quickly enter the cytoplasm and nucleus to stain the nucleic acid. The fluorescent dye in the cells produces a certain fluorescence intensity under the excitation of a laser with a specific wavelength, and this fluorescence intensity is positively correlated with the nucleic acid content of the cells. However, in actual use, due to the water absorption and light condensation characteristics of the nucleic acid fluorescent dye, the capillary guiding method is mostly used in the industry for the sampling of the dye solution.

[0033] The above-mentioned nucleic acid fluorescent dye is one of the above-mentioned dye solutions, and the dye solution can specifically be a solution that combines and colors the sample through chemical or other actions.

[0034] For example, when performing sample detection and observing and analyzing samples such as blood cells under an optical microscope or laser irradiation detection, since the sample itself is usually transparent, and there are many types of cells with relatively small volumes, in this case, if the sample is not stained, it is very difficult for us to accurately obtain the sample information. Therefore, the sample is usually stained with a dye solution, and then the corresponding sample detection is performed to obtain more reliable and accurate sample detection results.

[0035] This application proposes a dye solution extraction device. Refer to Figure 1 , Figure 1 is one of the front views of the first embodiment of the dye solution extraction device of this application. As Figure 1 shown, the dye solution extraction device includes a main body 3, a dye solution assembly 2, and a cover plate control assembly 1.

[0036] The dye solution assembly 2 is arranged on the main body 3. The dye solution assembly 2 includes a container 22 and a cover plate 21. The container 22 has a receiving cavity for storing the dye solution. The container 22 has an opening, and the receiving cavity communicates with the outside through the opening. The cover plate 21 is used to block or expose the opening.

[0037] Among them, the dye solution assembly 2 can be arranged in the groove of the main body 3. A clamping mechanism can be arranged on the outer wall of the container 22, and a slot mechanism matching the clamping mechanism can be arranged on the groove of the main body 3. When the container 22 is placed in the groove, the clamping mechanism and the slot mechanism can be clamped and matched to improve the stability between the dye solution assembly 2 and the main body 3.

[0038] The cover plate 21 can block the opening by approaching the opening, and can expose the opening by moving away from the opening.

[0039] When it is necessary to collect the dye solution, the cover plate 21 can be controlled to move away from the opening, exposing the space storing the dye solution in the accommodating cavity, so that the sampling needle or other sampling devices can enter to collect the dye solution.

[0040] When it is not necessary to collect the dye solution, the cover plate 21 can be controlled to approach the opening, blocking the space storing the dye solution in the accommodating cavity, and avoiding waste caused by a large amount of volatilization of the dye solution due to direct contact with the outside air.

[0041] The cover plate control assembly 1 includes a rotating shaft 12 and a rotating module 13. The rotating shaft 12 is rotatably connected to the main body 3. One end of the rotating shaft 12 is fixedly connected to one end of the cover plate 21, and the other end of the rotating shaft 12 is fixedly connected to the rotating module 13. The rotating module 13 is used to drive the rotating shaft 12 to rotate around its axis, so as to drive the other end of the cover plate 21 to move away from or approach the opening when the rotating shaft 12 rotates.

[0042] Specifically, the control of the cover plate 21 moving away from or approaching the opening can be realized through the cover plate control assembly 1.

[0043] The rotating shaft 12 can be rotatably connected to the main body 3. Alternatively, the cover plate control assembly 1 can further include a fixing member 11, and the rotating shaft 12 can also be rotatably connected to the fixing member 11. The fixing member 11 can be fixedly connected to the main body 3, and the rotating shaft 12 can pass through the fixing member 11 so that the rotating shaft 12 is rotatably connected to the fixing member 11.

[0044] The fixing member 11 can be integrally formed with the main body 3 or independent of each other, and this is not limited here.

[0045] Both ends of the rotating shaft 12 are fixedly connected to one end of the cover plate 21 and the rotating module 13 respectively. By driving the rotating shaft 12 to rotate relative to the main body 3 or the fixing member 11, the rotating module 13 can drive the other end of the cover plate 21 to rotate around the axis of the rotating shaft, so as to control the other end of the cover plate 21 to rotate around the axis of the rotating shaft in different directions, realizing the control of the other end of the cover plate 21 moving away from or approaching the opening.

[0046] The sampling assembly 4 is arranged on the main body 3. The sampling assembly 4 includes a sampling needle. The sampling assembly 4 is used to move the needle opening of the sampling needle into the accommodating cavity to extract the dye solution when the other end of the cover plate 21 moves away from the opening.

[0047] Specifically, the sampling assembly 4 can move in the horizontal direction relative to the main body 3. Among them, the sampling assembly 4 can control the movement of the sampling needle so that the sampling needle moves in the vertical direction relative to the main body 3.

[0048] When the cover plate 21 is opened, the sampling needle of the sampling assembly 4 can be controlled to extend into the dye solution assembly 2 to collect the dye solution, and the cover plate 21 can be closed after the sampling needle leaves the dye solution assembly 2, so as to realize the extraction of the dye solution, and avoid the volatilization or deterioration of the dye solution when it is in contact with air without sampling.

[0049] Based on the above method, the method of using the sampling needle to extract and transport the dye solution can be used to replace the traditional dye solution transportation method. Compared with the traditional method (such as: the method of transporting the dye solution through pipelines), using the sampling needle can minimize the waste that may be caused during each extraction of the dye solution. For example, it can avoid the situation of dye solution waste caused by a large amount of dye solution still remaining in the pipeline, and reduce the cost of the dye solution.

[0050] In addition, through the reasonable control of the cover plate 21, the possibility of the dye solution volatilizing or deteriorating due to long-term contact with the outside air can also be reduced, further reducing the loss of the dye solution and the cost of the dye solution.

[0051] Different from the prior art, in the technical solution of the present application, the dye solution assembly is arranged on the main body. The dye solution assembly includes a container and a cover plate. The container has a receiving cavity for storing the dye solution. The container has an opening, and the receiving cavity communicates with the outside through the opening. The cover plate is used to block or expose the opening. The rotating shaft is rotatably connected to the main body. One end of the rotating shaft is fixedly connected to one end of the cover plate, and the other end of the rotating shaft is fixedly connected to the rotating module. The rotating module is used to drive the rotating shaft to rotate around its axis, so as to drive the other end of the cover plate to move away from or close to the opening when the rotating shaft rotates, and the sampling needle can be controlled to move into the receiving cavity to extract the dye solution when the other end of the cover plate moves away from the opening. Based on the above method, the dye solution is sucked by the sampling needle, and by controlling the rotating module to drive the rotating shaft to rotate, the other end of the cover plate is driven to approach or move away from the opening, so as to realize that the opening is blocked or exposed by the cover plate. When it is necessary to extract the dye solution in the receiving cavity through the sampling needle, the opening can be exposed. When it is not necessary to extract the dye solution in the receiving cavity, the opening can be blocked. This not only avoids the waste of the dye solution caused by the pipeline transportation of the dye solution through the method of extracting the dye solution by the sampling needle, but also reduces the loss of the dye solution caused by volatilization, reduces the waste of the dye solution, and reduces the cost.

[0052] Moreover, timely blocking the opening when the dye solution is not needed to be extracted can also prevent the dye solution from deteriorating due to long-term contact with the outside air, avoiding greater waste of the dye solution.

[0053] In addition, through the rotating module 13, the control of the cover plate 21 is realized, and automation is achieved, which can improve the convenience of user operation.

[0054] In one embodiment, refer to Figures 2 to 6 , Figure 2 is one of the rear view schematic diagrams of the first embodiment of the dye solution extraction device of the present application. Figure 3One of the isometric schematic views of the first embodiment of the dye extraction device of the present application, Figure 4 The second front view schematic of the first embodiment of the dye extraction device of the present application, Figure 5 The second rear view schematic of the first embodiment of the dye extraction device of the present application, Figure 6 The second isometric schematic view of the first embodiment of the dye extraction device of the present application.

[0055] As Figures 1 to 6 shown, Figures 1 to 3 It is a schematic view when the other end of the cover plate 21 is controlled by the rotation module 13 to approach the opening, that is, a schematic view when closing the cover plate 21 of the dye component 2.

[0056] Figures 4 to 6 It is a schematic view when the other end of the cover plate 21 is controlled by the rotation module 13 to move away from the opening, that is, a schematic view when opening the cover plate 21 of the dye component 2.

[0057] The rotation module 13 includes a rotating member 131 and a pushing member 132.

[0058] The other end of the rotating shaft 12 is fixedly connected to one end of the rotating member 131.

[0059] The pushing member 132 is used to push the other end of the rotating member 131 to rotate around the axis of the rotating shaft 12, driving the rotating shaft 12 to rotate around its axis.

[0060] Specifically, the pushing member 132 can be a device that moves relative to the main body 3. The pushing member 132 can realize pushing the other end of the rotating member 131 to rotate around the axis of the rotating shaft 12 by abutting against the rotating member 131. The place where the pushing member 132 is used to abut against the rotating member 131 can have a flexible member or a rigid member, which are respectively used to realize flexible abutment or rigid abutment, and are not limited here. Flexible abutment can specifically be elastic abutment or other types of flexible abutment, which are not limited here. Exemplarily, the pushing member 132 can be fixedly connected to the sampling component 4, that is, the pushing member 132 can move with the horizontal movement of the sampling component 4, that is, the pushing member 132 can move horizontally as the sampling component 4 moves horizontally towards the dye component 2; the pushing member 132 can be arranged on the main body 3, and during the horizontal movement of the sampling component 4 towards the dye component 2, the pushing member 132 is driven to move horizontally. The pushing member 132 arranged on the main body 3 is also connected with a reset member, and the reset member can be a reset spring.

[0061] As Figures 1 to 3 shown, when the pushing member 132 does not abut against the rotating member 131 and push the rotating member 131, since both the rotating member 131 and the cover plate 21 are in their initial positions, that is, the other end of the cover plate 21 is just in contact with the opening at this time, the closing of the cover plate 21 is realized.

[0062] AsFigures 4 to 6 As shown, when the pushing member 132 abuts against the rotating member 131 and pushes the rotating member 131, the other end of the rotating member 131 can be rotated around the axis of the rotating shaft 12, driving the rotating shaft 12 to rotate along its axis, and further driving the other end of the cover plate 21 away from the opening, thus realizing the opening of the cover plate 21.

[0063] Based on the above method, by arranging the rotating member 131 and the pushing member 132 in the rotating module 13, the control of the other end of the cover plate 21 moving away from or approaching the opening can be realized, that is, the control of the opening and closing of the cover plate 21 of the dye solution assembly 2 can be realized. The structure is simple, the failure rate is relatively low, the possibility of dye solution volatilization or deterioration caused by the failure of the rotating module 13 is reduced, and the reliability of dye solution extraction is improved.

[0064] Optionally, the rotating module 13 further includes a weight member 133 and / or an elastic member (not shown in the figure).

[0065] The other end of the rotating shaft 12 is fixedly connected to the weight member 133, and the other end of the weight member 133 is used to drive the rotating shaft 12 to rotate under the action of gravity, so as to drive the other end of the cover plate 21 to approach the opening.

[0066] An elastic member is provided on the rotating shaft 12, and the elastic member is used to apply an elastic force to the rotating shaft 12 to drive the rotating shaft 12 to rotate, so as to drive the other end of the cover plate 21 to approach the opening.

[0067] Specifically, when the weight member 133 is provided, the other end of the rotating shaft 12 is fixedly connected to the weight member 133 in addition to the rotating module 13.

[0068] In the horizontal direction, the center of gravity position of the weight member 133 is different from the center of gravity position of the rotating member 131. Among them, in the horizontal direction, the center of gravity position of the cover plate 21 can be located between the center of gravity position of the rotating member 131 and the center of gravity position of the weight member 133.

[0069] When the weight member 133 is provided, by stopping controlling the pushing member 132 from pushing the rotating member 131 and using the driving of the gravity action of the weight member 133, it can be realized that when the weight member 133 moves under the action of gravity, it drives the rotating shaft 12 to rotate, thereby driving the other end of the cover plate 21 to approach the opening, and finally realizing the closing of the cover plate 21.

[0070] When the above elastic member is provided, by reasonably setting the elastic member, the rotational force of the elastic member on the rotating shaft 12 around its axis can be made such that when the pushing member 132 does not push the rotating member 131, this rotational force can drive the rotating shaft 12 to rotate, and further drive the other end of the cover plate 21 to approach the opening, and finally realize the closing of the cover plate 21.

[0071] Based on the above method, when the weight member 133 and / or the above elastic member are provided, it is possible to quickly close the cover plate 21 on the dye solution assembly 2 when stopping controlling the pushing member 132 from pushing the rotating member 131, further reducing the contact time between the dye solution and the outside air, further reducing the possibility of dye solution volatilization or deterioration, and improving the reliability of dye solution extraction.

[0072] In one embodiment, referring to Figure 7 , Figure 7 is an axonometric schematic diagram of the second embodiment of the dye solution extraction device of the present application. As Figure 7 shown, the rotating module 13 includes a motor 134.

[0073] The other end of the rotating shaft 12 is fixedly connected to the motor 134. The motor 134 is used to drive the rotating shaft 12 to rotate, so as to drive the other end of the cover plate 21 to move away from or close to the opening when the rotating shaft 12 rotates.

[0074] Specifically, by means of the motor 134, the rotating shaft 12 can be freely controlled to rotate in any direction around its axis, and thus the opening and closing of the cover plate 21 can be freely controlled, improving the convenience of dye solution extraction.

[0075] In one embodiment, referring to Figure 8 , Figure 8 is an axonometric schematic diagram of the third embodiment of the dye solution extraction device of the present application. As Figure 8 shown, the rotating module 13 includes a transmission member 135 and a push-pull member 136.

[0076] The other end of the rotating shaft 12 is fixedly connected to one end of the transmission member 135.

[0077] The push-pull member 136 includes a push-pull main body 1361, a push-pull rod 1362, and a slider (not shown in the figure). The push-pull main body 1361 is slidably connected to the slider relatively. The slider is rotatably connected to one end of the push-pull rod 1362. The other end of the push-pull rod 1362 is rotatably connected to the other end of the transmission member 135.

[0078] The push-pull member 136 is used to drive the other end of the push-pull rod 1362 to move away from or close to the push-pull main body 1361, drive the other end of the transmission member 135 to rotate around the axis of the rotating shaft 12, so as to drive the rotating shaft 12 to rotate, and drive the other end of the cover plate 21 to move away from or close to the opening when the rotating shaft 12 rotates.

[0079] The push-pull main body 1361 can be rotatably connected to the main body 3, or the push-pull main body 1361 can be rotatably connected to the main body 3. Among them, the rotation axis of the push-pull main body 1361 is parallel to the axis of the rotating shaft 12.

[0080] Specifically, the push-pull body 1361 is rotatably connected to the 11, so that when the push-pull body 1361 pushes and pulls the push-pull rod 1362, it can rotate relative to the main body 3, thereby forming a mechanical control structure in which the transmission member 135 rotates around the position where the rotating shaft 12 is located by pushing and pulling.

[0081] The push-pull member 136 pushes the push-pull rod 1362, causing the other end of the push-pull rod 1362 to move away from or close to the push-pull body 1361, so that the transmission member 135 rotatably connected to the other end of the push-pull rod 1362 can rotate around the position where the rotating shaft 12 is located, thereby driving the rotating shaft 12 to rotate, and further realizing the opening and closing of the control cover plate 21.

[0082] Based on the above method, a mechanical control structure for controlling the rotation of the rotating shaft 12 can be constructed by a device with push-pull ability, so as to realize the free control of the rotation of the rotating shaft 12 and improve the convenience of dye extraction.

[0083] Optionally, the push-pull member 136 is a push-pull electromagnet.

[0084] The push-pull electromagnet includes a push-pull body 1361, a push-pull rod 1362, the above-mentioned slider, an elastic member (not shown in the figure), and a coil (not shown in the figure).

[0085] The push-pull rod 1362 includes a first iron core, the slider is a second iron core, the first iron core is fixedly arranged on the push-pull body 1361, the second iron core is movably arranged on the push-pull body 1361, the first iron core and the second iron core are connected by an elastic member, and the coil is at least wound around the first iron core. When the push-pull electromagnet is energized or de-energized, the second iron core moves closer to or away from the first iron core, thereby driving the other end of the push-pull rod 1362 to move away from or close to the push-pull body 1361.

[0086] Specifically, the push-pull member 136 can specifically be the above-mentioned push-pull electromagnet, or other devices with the ability to push and pull the push-pull rod 1362, which can be determined according to actual needs and are not limited here.

[0087] In an embodiment, the dye extraction device may further include a sensor (not shown in the figure).

[0088] The sensor is arranged on the main body 3, and the sensor is used to sense and transmit the sensing information that the sampling component 4 moves to a preset position above the container 22, so as to drive the rotation module 13 after obtaining the sensing information.

[0089] Specifically, the sensor can specifically be an optocoupler sensor, or other types of sensors for detecting whether the sampling component 4 moves to a preset position above the container 22, and are not limited here.

[0090] After the sensor detects the sampling component 4 at a preset position above the container, it can drive the rotation module 13 to control the rotation of the rotating shaft 12 around its axis, so as to drive the other end of the cover plate 21 away from the opening when the rotating shaft 12 rotates, so that the sampling needle of the sampling component 4 can enter the container 22 to extract the dye solution.

[0091] When the sensor does not detect the sampling component 4 at a preset position above the container, it can also drive the rotation module 13 to control the rotation of the rotating shaft 12 around its axis, so as to drive the other end of the cover plate 21 close to the opening when the rotating shaft 12 rotates, so as to reduce the possibility that the dye solution in the container 22 volatilizes or deteriorates due to contact with the outside air.

[0092] When the sensor drives the rotation module 13, specifically, it can drive the motor 134 in the rotation module 13 described in the previous embodiment, or drive the push-pull member 136 in the rotation module 13 described in the previous embodiment. It can also drive other components in the rotation module 13, which is determined according to the actual structure and requirements of the rotation module 13 and is not limited here.

[0093] Based on the above method, the reliability of the dye solution extraction device can be improved. In one embodiment, see Figure 9 , Figure 9 is a schematic structural diagram of an embodiment of the cover plate and the seal of the present application. As Figure 9 shown, the dye solution extraction device further includes a seal 5.

[0094] The seal 5 is arranged on the side of the cover plate 21 facing the opening. The seal 5 is used to seal the gap between the cover plate 21 and the container 22 when the cover plate 21 blocks the opening.

[0095] Specifically, the seal 5 is an umbrella-shaped flexible member.

[0096] The umbrella top of the umbrella-shaped flexible member is fixedly connected to the side of the cover plate 21 facing the opening.

[0097] It should be noted that the seal 5 can also be a flexible member in other forms, which is not limited here.

[0098] The cross-sectional area of the seal 5 is larger than the cross-sectional area of the opening.

[0099] Based on the above method, the seal 5 can fill the gap between the cover plate 21 and the container 22, further reducing the contact between the dye solution and the outside air, further reducing the possibility that the dye solution volatilizes and is wasted or deteriorates due to contact with the air, and improving the reliability of the dye solution extraction.

[0100] The present application also proposes a sample analyzer. See Figure 10 , Figure 10 is a schematic structural diagram of an embodiment of the sample analyzer of the present application. As Figure 10As shown, the sample analyzer 60 includes a dye extraction device 61, which can be the dye extraction device described in any of the previous embodiments and will not be elaborated here.

[0101] Different from the prior art, in the technical solution of the present application, the dye assembly is arranged on the main body. The dye assembly includes a container and a cover plate. The container has a receiving cavity for storing the dye. The container has an opening, and the receiving cavity communicates with the outside through the opening. The cover plate is used to block or expose the opening. The rotating shaft is rotatably connected to the main body. One end of the rotating shaft is fixedly connected to one end of the cover plate, and the other end of the rotating shaft is fixedly connected to the rotating module. The rotating module is used to drive the rotating shaft to rotate around its axis, so as to drive the other end of the cover plate to move away from or close to the opening when the rotating shaft rotates, and can control the sampling needle to move into the receiving cavity to extract the dye when the other end of the cover plate moves away from the opening. Based on the above method, the dye is sucked by the sampling needle, and by controlling the rotating module to drive the rotating shaft to rotate, the other end of the cover plate is driven to approach or move away from the opening, so that the opening is blocked or exposed by the cover plate. When it is necessary to extract the dye in the receiving cavity through the sampling needle, the opening can be exposed. When it is not necessary to extract the dye in the receiving cavity, the opening can be blocked. This not only avoids the waste of dye caused by the pipeline transportation of dye by extracting the dye through the sampling needle, but also reduces the loss of dye caused by volatilization and reduces the waste of dye.
