Abstract
Description
[0001] This application is a divisional application of the patent application filed on July 24, 2019, with application number 201980048278.7 (international application number PCT / EP2019 / 069871) and entitled "mixing apparatus, mixing system and method for mixing substances in a closed container". Technical Field
[0002] This invention relates to a mixing apparatus, and more particularly to a mixing apparatus for mixing substances in a closed container. Background Technology
[0003] Hybrid devices of the prior art are known, in which ampoules are arranged, for example, on a rotating platform that can be pivoted by means of a drive. The rotating platform includes separate, specific supports for ampoules of different diameters, or the rotating platform includes finger-like patterns protruding from the platform surface, and different ampoules can be arranged between them, wherein, when pivoting, smaller ampoules roll back and forth between the fingers.
[0004] In another well-known mixing device, the holder for the ampoule is mounted on both sides, allowing it to rotate on both sides, wherein the holder can pivot by means of an actuator. An ampoule can be inserted into each container receiving portion of the holder.
[0005] With such a mixing device, there is a risk of ampoules becoming mixed up before or during insertion into the holder, or when the ampoules are removed from the holder. Additionally, inserting and removing ampoules is time-consuming. Summary of the Invention
[0006] The object of this invention is to provide a mixing device that reduces the possibility of contamination and facilitates the insertion and removal of containers containing the substances to be mixed. This is particularly important for patient samples, where container contamination must be avoided.
[0007] This objective is achieved by a mixing device having the features of the present invention. Other embodiments of the mixing device, mixing apparatus, and methods for operating the mixing device or mixing apparatus are defined by the features of the present invention.
[0008] The mixing device according to the invention includes: a drive unit having a driver and a shaft pivotable about a pivot axis and operatively connected to the driver, and including a pivotable receiving portion arranged on the shaft, wherein the pivot axis is oriented substantially horizontally, wherein the pivotable receiving portion includes a base plate and at least one retainer spaced apart therefrom, wherein the pivotable receiving portion is configured such that a holder for a container can be inserted between the base plate and the at least one retainer in the direction of the pivot axis. With this design, containers can be inserted into the holder independently of the mixing device, i.e., before they are inserted into the mixing device. Therefore, insertion can be performed in a short time. Furthermore, containers cannot be mixed during insertion because they can be placed in the holder without time pressure. Insertion of the holder with containers in the direction of the pivot axis is very easy and ergonomic. The drive unit includes a housing in which an electromechanical driver, with or without gears, is arranged. The drive unit may include a belt drive.
[0009] In one embodiment, the pivotable receiver is capable of pivoting at any angle about a pivot axis in both directions. This means, for example, that the pivotable receiver can rotate back and forth at any angle by means of a drive unit, or that the pivotable receiver can rotate once or several times about a pivot axis in one of the two rotational directions. This allows for optimal mixing of all possible substances within the container. Thus, powders or liquids, such as suspensions or emulsions, can be mixed. For example, whole blood, i.e., plasma or serum, can be mixed with blood cells or with additional substances. For example, the substances to be mixed can be filled into test tubes or ampoules. Ampoules comprise glass or plastic containers that are closed at the top with a cap containing a sealing septum. The septum contains a soft plastic, such as PTFE or silicone, that can be pierced with a pipette needle or tip. For example, such a cap can be screwed onto a container with a top opening using threads.
[0010] In one embodiment, the mixing device includes a control unit that can adjust the pivot angle, pivot speed, and pivot direction. By adjusting these values, optimal mixing of the substances can be achieved.
[0011] In one embodiment, the side of the substrate facing at least one holder is provided with a receiving portion aligned in the direction of the pivot axis, and the support of the container can be inserted into the receiving portion.
[0012] In one embodiment, the receiving portion includes a protrusion that can project into a complementary recess of the support. For example, the protrusion is an element extending directly from the substrate of the pivotable receiving portion. The protrusion can be a pin, such as a pin with a circular cross-section. However, other cross-sections are also contemplated. The protrusion can also be a slider, such as for a T-slot or dovetail slot. Alternatively, the receiving portion can include a recess into which the complementary protrusion of the support can project, and the recess also forms a pin-groove connection or a slider-groove connection.
[0013] In one embodiment, a plurality of receiving portions are arranged one after another along a pivot axis. For example, the receiving portions include a first receiving portion arranged in a region of the substrate near the axis and a second receiving portion arranged in a region of the substrate away from the axis. A first end of the support can be inserted into the first receiving portion, and a second end can be inserted into the second receiving portion. Thus, the position and orientation of each support are clearly and reliably defined.
[0014] Alternatively, an additional receiving portion aligned with the first receiving portion may be provided between it and a second receiving portion aligned with it in the direction of the pivot axis. The additional receiving portion provides additional support for the support or allows the insertion of shorter supports that do not extend along the entire length of the pivotable receiving portion.
[0015] In one embodiment, several receiving portions are arranged side-by-side in a direction transverse to the pivot axis. Therefore, several identical or different supports can be inserted adjacent to each other into the pivotable receiving portions, thereby allowing the contents of several containers to be mixed simultaneously. For example, the receiving portions are arranged symmetrically with respect to the pivot axis.
[0016] In one embodiment, the mixing device includes a first spacer and a second spacer. The first spacer is insertable into a receiving portion, and a container support is insertable therein. The second spacer is arranged between the receiving portions, and the container support rests on it. The spacers increase the distance between the inserted support and the substrate of the pivotable receiving portion. Advantageously, shorter containers are inserted into the support, and the distance between the upper end of the inserted container and the substrate should be substantially the same as that of longer containers. By grading the thickness of the spacers, it is possible to achieve that when shared containers are in the mixing device, their upper ends are substantially aligned with each other. Different spacers can be placed simultaneously on the pivotable receiving portion, thereby allowing different containers to be placed simultaneously in the mixing device with their upper ends substantially aligned.
[0017] In one embodiment, a drive plate is disposed in a first end region of the substrate, the drive plate being substantially perpendicular to the substrate and aligned substantially perpendicular to the pivot axis and connecting the axis to the substrate.
[0018] In one embodiment, the substrate is connected to at least one retainer via a drive board.
[0019] In one embodiment, a support element is provided in a second end region of the substrate opposite to the first end region. The support element includes a cylindrical sheath surface whose axis is aligned with the pivot axis.
[0020] In one embodiment, the substrate is connected to at least one retainer via a support element.
[0021] In one embodiment, the support element comprises a plate substantially perpendicular to the substrate and the pivot axis.
[0022] In one embodiment, the support element includes a central opening, and the substrate at least partially protrudes through the central opening.
[0023] In one embodiment, at least one connector is provided to connect the drive board to the support element.
[0024] In one embodiment, the drive plate includes at least one recess to receive at least one retainer. Alternatively, the drive plate may be provided with a protrusion in which at least one retainer is held, or at least one retainer is guided or clamped by a protrusion. For example, such a protrusion may be a rib or a pin.
[0025] In one embodiment, the support element includes at least one fastener for attaching at least one retainer. Such a fastener may include at least partially removable elements. For example, the fastener may be pivotable and may include a fixing element. Alternatively or additionally, the drive plate may also be provided with a fastener by which at least one retainer can be detachably secured.
[0026] In one embodiment, the mixing device includes a carrier unit having at least one roller, on which a support element and a sheath surface are rotatably mounted. The carrier unit is positioned relative to a pivotable receiver and a drive unit. The support element is pivotally mounted in the carrier unit, aligned with a shaft. Due to the double-sided bearing of the pivotable receiver, the dimensions of the corresponding carrier and the pivotable receiver must be less fixed, meaning they require less space and have a smaller mass to move.
[0027] In one embodiment, the support unit includes two or more rollers, with support elements rotatably mounted on the rollers and sheath surfaces. At least one roller may be equipped with a spring. At least one roller can be driven synchronously with the drive unit.
[0028] In one embodiment, the drive unit and the support unit are arranged on a common connecting plate. The connecting plate can be designed to be completely closed, or it can include at least one recess in the area of the pivotable receiving portion.
[0029] In one embodiment, at least one retainer includes at least one plate having at least one through opening, wherein the through opening is arranged to align with a container receiving portion formed in the support when the support is inserted.
[0030] In one embodiment, the internal dimension of the through opening is smaller than the internal dimension of the container receiving portion into which the support can be inserted. The internal dimension of the through opening may also be smaller than the external dimension of the container lid.
[0031] In one embodiment, at least one retainer includes a first plate and a second plate, wherein the distance between the substrate and the first plate is greater than the distance between the substrate and the second plate. The two plates may be independent of each other or may be connected to each other.
[0032] In one embodiment, the first plate and the second plate are integrally formed.
[0033] In one embodiment, at least one tab is integrally formed and substantially flush with at least one plate.
[0034] In one embodiment, at least one rib is integrally formed with at least one plate, extending along a pivot axis over at least a portion of the at least one plate. The at least one rib may be formed in one or both side edge regions of each plate. Alternatively or additionally, the rib may be located between two edge regions of each plate.
[0035] In one embodiment, at least one flap is integrally formed with at least one rib and is spaced apart from and parallel to at least one plate. At least one tab may be located at one or both of the two free ends of the retainer.
[0036] In one embodiment, the hybrid device includes at least one encoder that can determine the position of the pivotable receiving portion.
[0037] In one embodiment, the mixing device includes at least one locking device that can secure the position of the pivotable receiving portion.
[0038] In one embodiment, the mixing device includes at least one support for the container, which is inserted between the substrate and at least one retainer. At least one support can be additionally inserted into the receiving portion.
[0039] In one embodiment, each support includes a plurality of container receiving portions arranged along a longitudinal axis, formed between the two ends. The container receiving portions may, for example, be countersunk holes with a circular cross-section. Other cross-sections are also possible. Each container receiving portion may include at least one lateral opening extending laterally outward from the corresponding container receiving portion transverse to the longitudinal axis. The at least one opening may be a slot or a window. Each container receiving portion may have two lateral openings arranged opposite each other relative to the longitudinal axis and forming a channel in the support together with the container receiving portions. Thus, it is possible to provide one slot and one window, two slots, or two windows for each container receiving portion. Each container receiving portion or window of the support may be provided with a clamping tab that protrudes through the window into the corresponding container receiving portion, thereby enabling the container contained therein to be held in a clampable manner. On the side of the support including the window, the support may have a tab plate including all the clamping tabs. Alternatively, the clamping tabs may be integrally formed with the rest of the support.
[0040] The various embodiments of the aforementioned hybrid devices can be used in any combination, as long as they do not contradict each other.
[0041] The mixing apparatus according to the invention includes a frame on which the mixing device according to the invention is arranged.
[0042] The mixing device may include a working surface located on a frame, wherein the mixing equipment is arranged on the working surface.
[0043] In one embodiment, the mixing system includes a pipetting unit that enables the addition of fluid to or removal of fluid from a container in the mixing apparatus.
[0044] In one embodiment, the pipetting unit includes a delivery unit on which a pipette tip is disposed, and the pipette tip is movable horizontally and / or vertically in an area above the rack or above the work surface via the delivery unit.
[0045] In one embodiment, the mixing system includes a reading unit capable of reading markings from a container to be received by the mixing device. The markings may be selected from the group consisting of 1D barcodes, 2D barcodes, RFID tags, or the like. The reading unit can also identify markings placed on supports for receiving the container. The reading unit can also identify which positions of the container receiving section already contain a container and which positions are empty. It can also determine whether all supports for the container inserted into the mixing device are fully inserted between the substrate and the retainer.
[0046] The aforementioned embodiments of the mixing device can be used in any combination, as long as they do not contradict each other.
[0047] The method for operating a mixing device or mixing apparatus according to the present invention includes the following steps:
[0048] - Provides a mixing device according to the invention;
[0049] - Insert the support containing the container into the receiving part of the pivotable receiving part; and
[0050] - The pivotable receiving part is pivoted about the pivot axis by a drive unit.
[0051] For example, if the pivotable receiving portion includes a cylindrical pin and the bracket is provided with a corresponding complementary hole, the insertion can be an installation. Alternatively, if the pivotable receiving portion includes a slider and the bracket is provided with a corresponding complementary groove, the insertion can also be a push-in.
[0052] In one embodiment, the method includes the following steps:
[0053] - Remove the retaining element before inserting the bracket; and
[0054] - After the bracket is inserted, the retaining element is attached.
[0055] For example, the fastening element securing the retaining element in the corresponding receiving portion can be removed, and the retaining element can then be lifted and placed in a different position independent of the mixing equipment. Alternatively, the retaining element can be linearly pushed away from the area above the pivotable receiving portion by means of a sliding mechanism. In another alternative, the retaining element can be pivoted away from the area above the pivotable receiving portion in a plane by means of a torsion mechanism. If the retaining element is secured to the pivotable receiving portion, a bracket must be pushed into the pivotable receiving portion located below the retaining element, for example, along the pivot axis.
[0056] In one embodiment, the method includes the following steps:
[0057] - Before or during bracket insertion, the markings on the containers arranged in the bracket are read using a reading unit. If the markings are read during bracket insertion, each container can be assigned to a specific position in the bracket and correspondingly to the pivotable receiving section or mixing device. If reading is performed during insertion, the bracket must be inserted into the pivotable receiving section. If reading is performed before insertion, it must be ensured that the bracket is correctly inserted. To prevent incorrect insertion, the first and second receiving sections of the pivotable receiving section, and correspondingly the first and second ends of the bracket, can be designed differently. Furthermore, the markings applied to the bracket can also be read.
[0058] In one embodiment, the method includes the following steps:
[0059] - After pivoting the pivotable receiving part, remove the fluid from the container provided in the mixing device;
[0060] - Before pivoting the pivotable receiving section, the fluid is fed into a container located in the mixing device.
[0061] For example, the contents of a mother tube containing, for example, whole blood can be mixed with itself or with additional substances. After mixing, a portion of the whole blood can be pipetted from the mother tube to a daughter tube. The daughter tube may be empty or may contain substances such as reagents. The contents of the daughter tube can then be mixed again. After mixing, the stent and its container can be removed from the mixing device and transferred to the analyzer. To withdraw and / or add fluid from a container sealed by a cap including a septum, it is necessary, for example, to puncture the septum with a pipette needle.
[0062] The foregoing embodiments of the method can be used in any combination, as long as they do not contradict each other. Attached Figure Description

The drive plate 21 is provided with a groove 210 into which the retainer 400 can be inserted. The support plate 22 is provided with a fastener 222 through which the retainer 400 can be detachably attached. The connector 23 is designed as a laterally arranged round rod. A central opening 221 is provided in the support plate 22 through which the substrate 20 protrudes, and through which a retainer for a container can be inserted. In the variant of the pivotable receiving portion 2 shown, a support with a tall container can be inserted into the retainer 400. If a deeper container is to be inserted, the retainer 400 must be rotated 180 degrees so that the outward-facing surface of the plate 401 faces the substrate 20, and the open end of the retainer 400 faces the drive plate 21.
[0079] Figure 5 It shows Figure 4A bottom perspective view of a retainer 400. The retainer 400 includes a plate 401 with a slot 402 extending substantially along the entire length of the plate. The width of the slot 402 is less than the outer dimension of the container cap and greater than the piercing area of the container cap. Ribs 403 extend substantially along the entire length of the retainer 400 in two lateral edge regions. A first free end of the retainer 400 is formed in an open manner, while a second free end opposite to the first free end is formed in a closed manner at the side. At the open end of the retainer 400, a first tab 404 is provided, designed to be parallel to the plate 401 and slightly offset from the plate 401 in the region of the plate 401, and protruding beyond the first free end of the retainer 400. At the closed end of the retainer 400, a second tab 405 is provided, designed to be parallel to the rib 403 and slightly offset from the rib 403 in the region of the rib, and protruding beyond the second free end of the retainer 400.
