Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a reagent mixing device and medical equipment. Background Technology

[0002] In medical research, reagent mixing devices are needed for experiments such as immunology studies and antigen testing to mix reagents in the reagent chamber, maintaining a stable suspension for easy observation and testing. Current technology, to improve mixing speed and quality, typically involves tilting the reagent sleeve, biasing the reagent bottle onto the mixing device, and then rotating the bottle to utilize centrifugal force for powerful mixing. However, this setup requires precise alignment of the reagent bottle when placing or changing it, ensuring the tilt direction remains consistent for successful sample addition and removal. Furthermore, the light-blocking plates surrounding the bottle holder can interfere with bottle installation. Often, two additional bottle sleeves are provided for control experiments, requiring users to sequentially align both bottles for each experiment, significantly increasing the user's workload. Summary of the Invention

[0003] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a reagent mixing device that can automatically position the bottle sleeve, keeping the tilt direction of the bottle sleeve unchanged, thus reducing the operational burden.

[0004] This application also proposes a medical device having the above-mentioned reagent mixing device.

[0005] A reagent mixing device according to a first aspect of this application includes a base, a housing, a bottle sleeve, and a positioning assembly. The housing has an openable and closable accommodating cavity, and the base is accommodated in the accommodating cavity. The bottle sleeve is rotatably connected to the base and, in the vertical direction, is inclined in a direction away from the center of the base. An eccentric insert is installed at the bottom end of the bottle sleeve, and the end of the insert has a movable portion. The positioning assembly is installed on the housing and located below the insert. The positioning assembly includes a detection element, a first positioning element, and a driving element. The output end of the driving element is connected to the first positioning element to drive the first positioning element to rotate. When the first positioning element rotates, the movable portion can move with the first positioning element. The first positioning element has a first positioning hole for the insert to be inserted. The detection element is used to determine the position of the first positioning element. The first positioning element drives the bottle sleeve to rotate from the position to a preset direction by a preset angle through the insert.

[0006] According to an embodiment of this application, a reagent mixing device has at least the following beneficial effects: When using the mixing device, the user can first open the accommodating cavity and remove the base, thereby detaching the bottle sleeve on the base from the accommodating cavity, making it convenient for the user to place and install the reagent bottle. After the user installs the reagent bottle to be rotated onto the tilted bottle sleeve, the base is placed back into the accommodating cavity. Then, the accommodating cavity is closed, and the driving component is activated. The driving component controls the first positioning component to rotate one revolution, so that the insert at the bottom of the bottle sleeve is inserted into the first positioning hole. Subsequently, the first positioning component continues to drive the bottle sleeve to rotate. When the positioning component rotates to a preset position, the detection component can detect the first positioning component, thereby determining that the first positioning component has reached the preset rotation starting position. At this time, the positioning component completes initialization, and the bottle sleeve reaches the predetermined starting position. Afterward, as long as the driving component controls the positioning component to rotate a preset angle in a preset direction, the tilted bottle sleeve can be moved to the preset sample addition position, so that the tilting direction of the front and rear installed bottle sleeves remains unchanged. Because the positioning component rotates from the same position and in the same direction at the same angle after each initialization, even if the first positioning hole shifts after mixing the reagent or the insert shifts when placing the reagent bottle, the positioning component can automatically position and align the bottle sleeve, ensuring that the tilt direction of the reagent bottle remains unchanged each time it is installed. This facilitates subsequent sample addition and removal by the dispensing needle. By setting an openable and closable accommodating cavity, while ensuring that the reagent can be mixed under light-protected conditions, the user can remove the base before placing and installing the reagent bottle, avoiding interference from the outer shell structure with the user's hand movements and effectively improving the efficiency of reagent bottle installation. With the positioning component, the user only needs to place the base into the accommodating cavity, and the positioning component will automatically position the bottle sleeve, keeping the tilt direction of the bottle sleeve unchanged, saving the user the time and labor costs required for aligning the reagent bottle, effectively reducing the user's operational burden. In addition, besides positioning the tilt direction of the bottle sleeve, the positioning component can also directly control the rotation of the bottle sleeve and the reagent bottle. The positioning component integrates positioning and driving functions, which can effectively simplify the structure of the mixing device and improve the integration of the mixing device.

[0007] According to some embodiments of this application, the first positioning member includes a sliding sleeve and a baffle plate. The top surface of the sliding sleeve is provided with the first positioning hole. The end of the sliding sleeve opposite to the first positioning hole is provided with a driven shaft.

The base is provided with a placement groove. The first plate is provided with a first through hole located above the placement groove. The second plate is provided with a second through hole that matches the shape of the first through hole.

[0015] The medical device according to a second aspect of this application includes the reagent mixing device described in the above embodiments.

[0016] The medical device according to the embodiments of this application has at least the following beneficial effects: The positioning component inside the reagent mixing device allows the user to automatically position the bottle sleeve simply by placing the base into the receiving cavity, ensuring the bottle sleeve's tilt direction remains unchanged. This eliminates the time and labor costs required for the user to align the reagent bottle, effectively reducing the user's operational burden. Furthermore, in addition to positioning the tilt direction of the bottle sleeve, the positioning component can also directly control the rotation of the bottle sleeve and the reagent bottle. The positioning component integrates both positioning and driving functions, effectively simplifying the structure of the mixing device and improving its integration.

[0033] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0034] Reference Figure 1 and Figure 2As shown, a reagent mixing device according to an embodiment of this application includes a base 100, a housing 200, a bottle sleeve 300, and a positioning component 400. The base 100 has at least two mixing positions 110, which are hollow areas for the bottle sleeve 300 and the reagent bottle within it to move. The housing 200 has an openable and closable receiving cavity 210, in which the base 100 is housed. The bottle sleeve 300 and the mixing positions 110 are arranged in a one-to-one correspondence. The bottle sleeve 300 is rotatably connected to the base 100 and rotates within the mixing positions 110. Vertically, the bottle sleeve 300 is inclined towards the direction away from the center of the base 100. An eccentric insert 310 is installed at the bottom end of the bottle sleeve 300, meaning the central axis of the insert 310 is parallel to but not collinear with the rotation axis of the bottle sleeve 300. The insert 310 extends vertically away from the bottle sleeve 300, and its end has a movable portion (not shown in the figure). (Exit); Positioning component 400 is installed on housing 200 and located below insert 310. Positioning component 400 includes detection component 410, first positioning component 420 and driving component 430. The first positioning component 420 and bottle sleeve 300 are respectively set and abut against the movable part. The output end of driving component 430 is connected to the first positioning component 420 to drive the first positioning component 420 to rotate. When the first positioning component 420 rotates, the movable part can follow the first positioning component 420 to move so that the insert 310 is stationary relative to the first positioning component 420. The first positioning component 420 is provided with a first positioning hole 401. The first positioning hole 401 and the insert 310 are inserted and matched. When the first positioning component 420 rotates to a preset position, the detection component 410 is used to determine the position of the first positioning component 420. The first positioning component 420 drives the bottle sleeve 300 to rotate from that position to a preset direction by a preset angle through the insert 310.

[0035] Understandably, when using the mixing device, the user can first open the accommodating cavity 210 and remove the base 100, thereby detaching the bottle sleeve 300 from the accommodating cavity 210, making it convenient for the user to place and install the reagent bottle. After the user installs the reagent bottle to be rotated onto the tilted bottle sleeve 300, the base 100 is placed back into the accommodating cavity 210, and then the accommodating cavity 210 is closed to ensure the reagent bottle is in a stable working environment. Subsequently, the drive unit 430 is activated, which controls the first positioning member 420 to rotate one revolution. Since the sliding member is eccentric, and the sliding member and the first positioning hole 401 are interlocked, the first positioning hole 401 is also eccentric, and the eccentric position of the first positioning hole 401 corresponds to that of the sliding member. During the rotation of the first positioning member 420, the first positioning hole 401 and the moving part move with the first positioning member 420, while the sliding member moves relative to the first positioning member 420. When the first positioning member 420 is stationary, there will always be a position where the first positioning hole 401 rotates exactly below the sliding member, so that the insert 310 at the bottom of the bottle sleeve 300, along with its movable part, is inserted into the first positioning hole 401, making the bottle sleeve 300 stationary relative to the first positioning member 420. The driving member 430 controls the first positioning member 420 to continue to drive the bottle sleeve 300 to rotate. When the first positioning member 420 rotates to the preset position, the detection member 410 can detect the positioning member and thus determine the position of the first positioning member 420. At this time, the positioning component 400 completes initialization, and the first positioning member 420 and the bottle sleeve 300 reach the preset rotation starting point position. After that, as long as the driving member 430 controls the positioning member to rotate by the preset angle, it can drive the tilted bottle sleeve 300 to move to the preset sample addition position, so that the tilt direction of the front and rear installed bottle sleeves 300 remains unchanged. Since the positioning component 400 rotates from the same position and in the same direction at the same angle after each initialization, even if the first positioning hole 401 shifts after mixing the reagent or the insert 310 shifts when picking up or putting down the reagent bottle, the positioning component 400 can automatically position and align the bottle sleeve 300, ensuring that the tilt direction of the reagent bottle remains unchanged each time it is installed, which facilitates subsequent sample addition and removal by the dispensing needle. By setting an openable and closable accommodating cavity 210, the user can remove the base 100 and then place the reagent bottle in place, provided that the reagent can be mixed under light-proof conditions. This avoids the structure of the outer shell 200 interfering with the user's hand movements, effectively improving the installation efficiency of the reagent bottle. By setting the positioning component 400, the user only needs to place the base 100 into the accommodating cavity 210, and the positioning component 400 will automatically position the bottle sleeve 300, ensuring that the tilt direction of the bottle sleeve 300 remains unchanged, saving the user the time and labor costs required to align the reagent bottle, and effectively reducing the user's operational burden.In addition, the positioning component 400 can not only position the tilt direction of the bottle sleeve 300, but also directly control the rotation of the bottle sleeve 300 and the reagent bottle. The positioning component 400 integrates positioning and driving functions, which can effectively simplify the structure of the mixing device and improve the integration of the mixing device. With at least two mixing positions 110 and bottle sleeves 300 corresponding to each mixing position 110, users can install at least two reagent bottles, which is convenient for users to conduct control experiments and improves the functionality of the mixing device.

[0036] Reference Figure 3 It is understandable that the insert 310 is a universal ball, and the movable part is the steel ball at the end of the universal ball. The bottom end of the bottle sleeve 300 is provided with a connecting part 313, and the connecting part 313 is connected to a retainer 314. The retainer 314 is provided with an eccentric mounting hole 301. The universal ball is installed in the mounting hole 301. The connecting part 313 is sleeved on the first bearing 315. The bottle sleeve 300 is rotatably connected to the base 100 through the first bearing 315. The first bearing 315 can improve the operational stability of the bottle sleeve 300. The side wall of the bottle sleeve 300 is provided with a spring piece 311. One end of the spring piece 311 is connected to the bottle sleeve 300, and the other end is offset towards the center of the bottle sleeve 300 along the radial direction of the bottle sleeve 300. The bottle sleeve 300 is also provided with a relief part 312 for avoiding the spring piece 311. The relief part 312 is a hollow structure set around the spring piece 311. When the first positioning component 420 rotates, the steel ball at the end of the universal ball rolls with the first positioning component 420, while the main body of the universal ball remains stationary relative to the first positioning component 420 until the first positioning hole 401 moves below the universal ball and the universal ball inserts into the first positioning hole 401. The universal ball has advantages such as simple structure and low cost. Setting the insert 310 as a universal ball can effectively simplify the structure of the bottle sleeve 300 and reduce the production and maintenance costs of the bottle sleeve 300. In addition, the spherical structure of the universal ball can play a certain guiding role, helping the universal ball to quickly insert into the first positioning hole 401 and improve the positioning efficiency of the first positioning component 420. By setting the spring piece 311, after the reagent bottle is installed into the bottle sleeve 300, the spring piece 311 will press against the side wall of the reagent bottle, thereby fixing the reagent bottle and avoiding problems such as shaking and rotation of the reagent bottle during the rotation of the bottle sleeve 300, effectively improving the installation stability of the reagent bottle.

[0037] Reference Figure 4It is understood that the first positioning element 420 includes a sliding sleeve 421 and a baffle 422. The top surface of the sliding sleeve 421 is provided with a first positioning hole 401. The end of the sliding sleeve 421 opposite to the first positioning hole 401 is provided with a driven shaft 423. The driven shaft 423 is provided with a driven gear 4232. The driving element 430 is provided with a motor. The output end of the motor is provided with a driving gear 431 that meshes with the driven gear 4232. The baffle 422 is installed on the driven shaft 423. The detection element 410 is provided with a photoelectric switch. The accommodating cavity 210 is provided with a second fixed sheet metal 252. The photoelectric switch is installed on the second fixed sheet metal 252. Since the positions of the first positioning hole 401 and the baffle 422 are relatively constant, the photoelectric switch can determine the position of the first positioning element 420 by detecting the position of the baffle 422. In particular, the first positioning element 420 is provided in correspondence with the bottle sleeve 300. There are at least two first positioning elements 420. At least two first positioning elements 420 are arranged at intervals along the circumference of the driving gear 431. The photoelectric switch and baffle 422 are set to detect the rotation angle of the sliding sleeve 421, thereby determining the position of the first positioning hole 401. The photoelectric switch reacts quickly and detects accurately, which can effectively improve the positioning accuracy and sensitivity of the positioning component 400, and facilitate the subsequent driving component 430 to accurately align the bottle sleeve 300.

[0038] Reference Figure 2 and Figure 4 It is understood that the bottom end of the base 100 is provided with a cavity 140 for accommodating the first positioning member 420. The sliding sleeve 421 and the driven shaft 423 slide in a vertical direction, and the sliding sleeve 421 can rotate with the driven shaft 423. The driven shaft 423 is provided with a positioning platform 4231. The first positioning member 420 also includes a spring 424. The spring 424 is sleeved on the driven shaft 423, and the two ends of the spring 424 abut against the sliding sleeve 421 and the positioning platform 4231 respectively. After the user places the base 100 into the receiving cavity 210, if the position of the insert 310 and the first positioning hole 401 do not correspond, the insert 310 will press down on the sliding sleeve 421, causing the sliding sleeve 421 to move downward along the axis of the driven shaft 423 until the insert 310 and the first positioning hole 401 correspond. Under the action of the spring 424, the sliding sleeve 421 moves upward along the axis of the driven shaft 423, allowing the insert 310 to be inserted into the first positioning hole 401. By setting the spring 424, problems such as the rigid contact between the insert 310 and the sliding sleeve 421 after the base 100 is placed into the receiving cavity 210, and the base 100 protruding above the sliding sleeve 421 and being uneven, which would cause instability of the base 100, can be avoided. At the same time, problems such as the collision noise caused by the base 100 falling directly after the insert 310 is inserted into the first positioning hole 401 can be avoided, effectively improving the operational stability of the positioning component.

[0039] Reference Figure 1 , Figure 2 and Figure 4It is understood that the outer casing 200 is provided with a second positioning member 240, which is located in the receiving cavity 210. The second positioning member 240 is used to position the base 100 on the horizontal plane. Due to the presence of a spring 424, the sliding sleeve 421 has a certain displacement range in the vertical direction, i.e., the axial direction of the driven shaft 423. This allows the user to fix the base 100 before performing the positioning operation. The user can fix the base 100 first, so that the insert 310 presses down the sliding sleeve 421, and then perform the positioning operation. At this time, by setting the second positioning member 240, after the user places the base 100 into the receiving cavity 210, the second positioning member 240 can position the base 100 on the horizontal plane, avoiding problems such as vibration and displacement of the base 100 during the rotation of the sliding sleeve 421. This effectively improves the installation stability of the base 100 and enhances the structural stability of the mixing device.

[0040] Continue to refer to Figure 1 , Figure 2 and Figure 4 It is understandable that the second positioning element 240 is set as a positioning pin, which is located on the bottom wall of the accommodating cavity 210. The base 100 is provided with a second positioning hole (not shown in the figure), and the positioning pin is provided with a guide part, which is the arc surface at the top of the positioning pin. The guide part is used to guide the positioning pin into the second positioning hole. By setting the second positioning element 240 as a positioning pin, when the user places the base 100, he only needs to insert the positioning pin into the second positioning hole to complete the installation of the base 100. At this time, the base 100 and the accommodating cavity 210 can be approximately regarded as a plug-in fit. Setting the second positioning element 240 as a positioning pin can further simplify the structure of the mixing device. While ensuring the stable installation of the base 100, it can minimize the influence and interference of the outer shell 200 on the base 100, making the base 100 plug-and-play, simplifying the installation and removal process of the base 100, making it convenient for users to install and remove reagent bottles, and improving the user experience.

[0041] Reference Figure 1 and Figure 5It is understood that the base 100 is equipped with a lifting member 130. Specifically, the base 100 is provided with a fifth through hole 103 that matches the shape of the handle 131. The lifting member 130 is installed in the fifth through hole 103 and the bottom of the lifting member 130 is engaged with the base 100 by a locking block 132. The lifting member 130 is provided with a handle 131, which passes through the fifth through hole 103 and is located on the side of the base 100 away from the positioning component 400. The handle 131 is provided with an operation hole 102 for the user's fingers to pass through. After the user opens the receiving cavity 210, they can use their fingers to pass through the operation hole 102 to grasp the handle 131. By pulling up the handle 131, the base 100 is pulled away from the receiving cavity 210. By setting up the lifting member 130, the handle 131 of the lifting member 130 can make it convenient for the user to quickly pull out the base 100 containing the reagent bottle, which has a larger mass, further improving the user experience and the ease of use of the mixing device.

[0042] Reference Figure 2 and Figure 5 It is understood that the outer casing 200 includes a light shield 220 and a light shield plate 230. The light shield 220 consists of a base plate 222 and an integrally formed side plate 223. A second positioning member 240 is disposed on the base plate 222. The side plate 223 and the base plate 222 are bolted together and enclose a receiving cavity 210. The light shield plate 230 is detachably connected to the side plate 223 of the light shield 220 and is located above the base 100. The light shield plate 230 is used to open or close the receiving cavity 210. The outer casing 200 mainly consists of the light shield 220 and the light shield plate 230. When the user installs the light shield plate 230, the receiving cavity 210 can be closed, providing a light-proof environment for the reagents in the reagent bottle. When the user removes the light shield plate 230, the receiving cavity 210 can be opened, and the base 100 can be removed from the user's possession. With this design, the outer casing 200 has a simple structure and is easy to assemble, which can further simplify the structure of the mixing device and facilitate the assembly and use of the outer casing 200.

[0043] It should be added that the inner wall of the side plate 223 is provided with a guide 224. The guide 224 is used to guide the second positioning member 240 and the second positioning hole to align. Specifically, the guide is a guide rib, and the height of the guide rib gradually increases downward in the vertical direction. When the user places the base 100 into the receiving cavity 210, the guide rib can guide the base 100 to move, preventing the base 100 from shifting, so that the second positioning hole can be stably moved to the top of the second positioning member 240, that is, the positioning pin. This saves the user the time and labor costs required to adjust the position of the base 100, and further improves the ease of use of the mixing device.

[0044] Continue to refer to Figure 2 and Figure 5It is understood that the bottom of the light shield 220 is provided with a mounting bracket 440 and a first fixed sheet metal 251. The driving component 430 is mounted on the mounting bracket 440. The driven shaft 423 is rotatably connected to the mounting bracket 440 through a second bearing 426. The first fixed sheet metal 251 is equipped with a control circuit board 253. The detection component 410 and the driving component 430 are electrically connected to the control circuit board 253 respectively. The control circuit board 253 is provided with a terminal block 254 for connecting an external power supply. The bottom of the light shield 220 is connected to a cover body 250. The driving component 430, the mounting bracket 440 and the first fixed sheet metal 251 are all housed in the cover body 250. The terminal block 254 is installed at the bottom of the cover body 250. By setting up the cover 250, on the one hand, when the mixing device is in operation, the cover 250 can provide stable support for the outer shell 200, the base 100 and the positioning component 400, further improving the operational stability of the mixing device. On the other hand, the cover 250 can hide the drive component 430, the control circuit board 253 and other structures. Together with the outer shell 200 that houses the base 100, the outer surface of the mixing device is clean and tidy when in operation, which can effectively improve the appearance of the mixing device.

[0045] Reference Figures 5 to 7It is understood that the light-shielding plate 230 includes a first plate 231 and a second plate 232. The first plate 231 is connected to the light-shielding cover 220. The base 100 is provided with a reagent position 120, which is provided with multiple placement slots 101 for storing reagent bottles. The multiple placement slots 101 are arranged around the mixing position 110. The placement slots 101 are inclined, and the angle between the bottom surface of the placement slot 101 and the horizontal plane is about 8°. The first plate 231 is provided with a first through hole 2302. Located above the placement slot 101, the second plate 232 has a second through hole 2303 that matches the shape of the first through hole 2302. The first plate 231 has a sliding groove 2301, and the second plate 232 has a slider 2321 fitted into the sliding groove 2301. A gripper 2322 is located on the side of the second plate 232 opposite to the slider 2321. The second plate 232 is slidably connected above the first plate 231 to adjust the relative position of the second through hole 2303 and the first through hole 2302. The placement slot 101 is tilted so that the reagent in the reagent bottle on the placement base 100 is tilted, thereby minimizing the amount of reagent in the bottle. Before mixing, the user can control the movement of the second plate 232 via the gripper 2322, thereby controlling the working environment of the reagent. Specifically, when the user pushes the gripper 2322, the second plate 232 moves accordingly. When the second through-hole 2303 on the second plate 232 coincides with the first through-hole 2302 on the first plate 231, the external optical fiber can pass through the second through-hole 2303 and the first through-hole 2302 in sequence to illuminate the reagent bottle in the reagent position 120, so that the reagent in the reagent bottle is in a non-light-shielded environment. When the second through-hole 2303 on the second plate 232 and the first through-hole 2302 on the first plate 231 are misaligned, the second plate 232 will block the first pupil, so that the reagent in the reagent bottle is in a light-shielded environment, and the light-shielding plate 230 is set to be fixed. The first plate 231 and the sliding second plate 232 control the relative position of the second through hole 2303 and the first through hole 2302 by moving the second plate 232. This allows the user to freely switch the working environment of the reagent, adding a non-light-shielded operation option to the mixing device, further improving the functionality of the mixing device and expanding its application range. In addition, the first plate 231 is also provided with a third through hole 2304, which is located above the bottle sleeve 300. The second plate 232 is provided with a fourth through hole 2305 that matches the shape of the third through hole 2304. When the third through hole 2304 and the fourth through hole 2305 are in the same position, the light-shielding plate 230 does not need to be removed, and the external sampling needle can perform sampling operations on the reagent bottle on the bottle sleeve 300.

[0046] Reference Figure 6It should be added that, along the width direction of the first plate 231, the width of the second plate 232 can be slightly smaller than the width of the first plate 231, so that when the user moves the second plate 232, the edge of the second plate 232 will not detach from the upper surface of the first plate 231, avoiding the situation where part of the edge of the second plate 232 protrudes outside the mixing device, and further improving the appearance of the mixing device.

[0047] Reference Figure 1 It should be added that the bottom of the light shield 220 is provided with a groove (not shown in the figure) that matches the shape of the first plate 231, and a positioning block 221 is provided in the groove. The first plate 231 is provided with a positioning groove 2306 that matches the shape of the positioning block 221. While the first plate 231 and the groove are engaged, the positioning block 221 and the positioning groove 2306 are engaged. This setting can effectively improve the installation stability of the light shield 230, and the positioning block 221 can add a foolproof function to the positioning groove 2306, reduce the installation direction of the first plate 231, and make it easier for users to assemble the mixing device more quickly.
