DETAILED DESCRIPTION

The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention. In the drawings and the following description, at least part of the known structures and technologies are not shown in order to avoid unnecessary ambiguity of the present invention; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

The directional words appearing in the following description are all directions shown in the figure, and do not limit the specific structure of the reagent container carrier and the carrier system of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" 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 directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

In order to better understand the present invention, the reagent container transport device and transport system according to the embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 4 .

1 , a reagent container transporting device is provided according to an embodiment of the present invention, comprising: a container seat 10 , a first guide assembly 20 and a second guide assembly 30 .

The container seat 10 includes a fixing portion 11 and a receiving portion 12, wherein the receiving portion 12 can receive a reagent container C and is rotatable relative to the fixing portion 11. The reagent container C contains a reagent. The contact surface between the receiving portion 12 and the reagent container C can be filled with a rubber-like elastic material to prevent the reagent container C from being scratched by the receiving portion 12 during movement, and also to slow down the shaking of the reagent container C.

The first guide assembly 20 can at least guide the accommodating portion 12 to flip outward or inward relative to the fixing portion 11. After the reagent container C is flipped outward, it is convenient to take and place the reagent container C.

The second guide assembly 30 is connected to the fixing portion 11 , and drives the fixing portion 11 to reciprocate between the first position and the second position, so that the accommodating portion 12 drives the reagent container C away from or close to the reagent needle N, and the reagent needle N is connected to a liquid path system.

The reagent container carrier provided in the embodiment of the present invention actively moves the reagent container C to the vicinity of the reagent needle N through the first guide component 20 and the second guide component 30, while the reagent needle N is fixed, thereby avoiding the problem of wear, breakage or jamming of the liquid path system connected to the reagent needle N. In addition, the first guide component 20 can guide the reagent container C to flip outward when it is away from the reagent needle N, which is convenient for taking and placing the reagent container. The overall structure is simple, compact, and easy to operate.

The specific structures of the components of the reagent container carrying device provided by the embodiment of the present invention are described in detail below with reference to the accompanying drawings.

Please refer to Figures 2 and 3. The receiving portion 12 of the container holder 10 can be configured to receive a portion of the reagent container C, rather than the entire reagent container C, so that most of the side surfaces of the reagent container C can be exposed to the outside, thereby reducing the weight and making it easier for operators to hold most of the side surfaces of the reagent container C to take it out of the receiving portion 12 or place it in the receiving portion 12.

When the second guide assembly 30 drives the fixing portion 11 to reach the first position, the accommodating portion 12 drives the reagent container C to assume a first posture to move away from the reagent needle N, as shown in FIG2. When the second guide assembly 30 drives the fixing portion 11 to reach the second position, the accommodating portion 12 drives the reagent container C to assume a second posture to move closer to the reagent needle N, and a predetermined angle is formed between the first posture and the second posture.

As an optional embodiment, the first position is located below the second position, and when the fixing portion 11 moves from the second position toward the first position, the accommodating portion 12 drives the reagent container C to follow the fixing portion 11 to move downward and gradually flip outward from the second posture to the first posture; when the fixing portion 11 moves from the first position toward the second position, the accommodating portion 12 drives the reagent container C to gradually flip inward from the first posture to the second posture and follow the fixing portion 11 to move upward.

It is understandable that the first position and the second position may also be on the same horizontal line or at a certain angle to the horizontal line, including, for example but not limited to, the first position being located to the right of the second position. Thus, when the fixing portion 11 moves from the second position toward the first position, the containing portion 12 drives the reagent container C to follow the fixing portion 11 to move to the right and gradually flip outward from the second posture to the first posture; when the fixing portion 11 moves from the first position toward the second position, the containing portion 12 drives the reagent container C to gradually flip inward from the first posture to the second posture and follows the fixing portion 11 to move to the left.

Further, the second guide assembly 30 can be a sliding movable part or a rolling movable part. The embodiment of the present invention takes a sliding movable part as an example for explanation. The second guide assembly 30 includes a guide rail 31 and a second slider 32 moving along the guide rail 31. The fixed part 11 of the container seat 10 includes a bracket 11a. The second slider 32 is connected to the bracket 11a, so that the second slider 32 drives the fixed part 11 to reciprocate between the first position and the second position along the guide rail 31 through the bracket 11a.

Further, the first guide assembly 20 includes a slideway 21 and a first slider 22 that moves along the slideway 21. The slideway 21 includes a first slideway portion 21a and a second slideway portion 21b that are arranged at a predetermined angle, and the connection between the two is smooth; the second slideway portion 21b is arranged parallel to the guide rail 31, and the accommodating portion 12 is pivotally connected to the first slider 22. The first slider 22 can be a sliding moving component or a rolling moving component, such as a roller. When the first slider 22 is a rolling moving component, it can slide along the slideway 21 while rotating around its own axis. Compared with the sliding moving component, the friction between it and the slideway 21 can be reduced, so that the first slider 22 can run more smoothly.

As an optional embodiment, the first slider 22 can be driven by a motor to drive the fixing portion 11 to reciprocate between the first position and the second position along the slideway 21. In addition, the first slider 22 can also be manually operated to reciprocate between the first position and the second position along the slideway 21. In order to facilitate manual operation by an operator, a handle 13 can be provided at a suitable position of the container seat 10, for example, the handle 13 can be provided at the outermost side of the accommodating portion 12, as shown in FIG. 2 .

Thus, when the first slider 22 moves along the second slide portion 21 b , the accommodating portion 12 is guided to move along with the fixing portion 11 ; when the first slider 22 moves along the first slide portion 21 a , the accommodating portion 12 is guided to gradually flip inward or outward relative to the fixing portion 11 .

As an optional embodiment, the first guide assembly 20 and the second guide assembly 30 can be located on the same side of the reagent needle N to reduce the overall size of the container seat 10 and facilitate the placement of the reagent container C, as shown in Figure 2. It can be understood that the first guide assembly 20 and the second guide assembly 30 can also be located on both sides of the reagent needle N, which is not limited here.

As an optional embodiment, the reagent needle N can be placed vertically, and the guide rail 31 in the second guide assembly 30 is placed vertically parallel to the axial direction of the reagent needle N. At this time, the first position is located below the second position. When the fixed part 11 moves from the second position toward the first position, the first slider 22 moves along the second slide part 21b, the accommodating part 12 is guided to move with the fixed part 11, and drives the reagent container C to gradually flip outward from the second posture, that is, the horizontal state, to the first posture, so that the operator can take and place the reagent container C; when the fixed part 11 moves from the first position toward the second position, the first slider 22 moves along the first slide part 21a, and the accommodating part 12 is guided to gradually flip inward from the first posture to the second posture, that is, the horizontal state relative to the fixed part 11, and drives the reagent container C to gradually follow the fixed part 11 to move upward until the second position, at which time, the reagent container C approaches the reagent needle N in a horizontal state, so that the reagent needle N is inserted into the reagent container C to start absorbing the reagent. There is a predetermined angle θ between the first posture and the second posture, as shown in Figure 3.

It is understandable that the reagent needle N may also be placed at a certain angle relative to the horizontal plane, and the second guide assembly 30 may also be placed not parallel to the axial direction of the reagent needle N. The angle needs to ensure that when the accommodating portion 12 of the container seat 10 approaches the reagent needle N in a non-horizontal state, the reagent capacity in the reagent container C is sufficient and does not overflow during the flipping process, or when the accommodating portion 12 of the container seat 10 approaches the reagent needle N in a horizontal state, the reagent needle N can be inserted into the reagent container C at a certain angle without bending the reagent needle and can absorb enough reagent.

As an optional embodiment, the first guide assembly 20 can also be a push rod, which is arranged near the guide rail 31 in the second guide assembly 30 and is located below the receiving portion 12. After the reagent needle N absorbs enough reagent from the reagent container C, the operator operates the handle 13 to move the container seat 10, so that the fixed portion 11 drives the receiving portion 12 to move toward the first position along the guide rail 31. When the bottom of the receiving portion 12 contacts the push rod, the receiving portion 12 can be guided to flip outward relative to the fixed portion 11, so that the reagent container C is in the first posture, which is convenient for the operator to take out the reagent container C and replace it with the next reagent container C. When the operator operates the handle 13 to move the container seat 10, so that the fixed portion 11 drives the receiving portion 12 to move toward the second position along the guide rail 31, the push rod guides the receiving portion 12 to flip inward relative to the fixed portion 11 to the second posture, so that the bottom of the receiving portion 12 leaves the push rod and moves to the second position along the guide rail 31 together with the fixed portion 11. In order to prevent the receiving portion 12 from rotating relative to the fixed portion 11 when it is close to the reagent needle N, a limiter can be provided at a position close to the reagent needle N.

In addition, a roller or a cam may be provided on the top of the push rod to smoothly flip the receiving portion 12 relative to the fixing portion 11. At the same time, in order to reduce the impact when the bottom of the receiving portion 12 contacts the top of the push rod or to prevent the bottom of the receiving portion 12 from being scratched, a rubber elastic member may be provided on the outer surface of the roller or the cam.

For ease of description, the following description takes the technical solution in which the first guide component 20 is a combination structure of a slideway 21 and a first slider 22, the first guide component 20 and the second guide component 30 are both located on the same side of the reagent needle N, and the reagent needle N is placed vertically as an example.

As shown in FIG. 2 and FIG. 3 , the fixing portion 11 further includes two side plates 11 b spaced apart from each other. A rotation shaft 12 a is disposed at the bottom of the accommodating portion 12 . The rotation shaft 12 a is disposed between the two side plates 11 b and rotatably connected to the two side plates 11 b .

In addition, the fixing portion 11 further includes a support shaft 11c, which is fixed between the two side plates 11b and spaced apart from the rotating shaft 12a. When the accommodating portion 12 is, for example, in a horizontal state close to the reagent needle N, the support shaft 11c and the rotating shaft 12a jointly support the accommodating portion 12. Both ends of the support shaft 11c can be fixed to the two side plates 11b by, for example, but not limited to, screws.

As an optional embodiment, the support shaft 11c and the rotating shaft 12a can be set as cylinders with the same diameter. At this time, the rotating shaft 12a is in line contact with the bottom of the accommodating portion 12. In order to increase the force-bearing area at the bottom of the accommodating portion 12, the portion of the rotating shaft 12a that contacts the bottom of the accommodating portion 12 can also be set as a plane. In order to facilitate processing, the rotating shaft 12a can be set as a cylinder, and a part of the circumferential surface of the cylinder is removed axially, or two symmetrical parts are removed axially, and the distance from the plane of the removed part to the central axis is equal to the radius of the support shaft 11c. The two ends of the rotating shaft 12a are further provided with a stepped shaft with a smaller diameter, and the two side plates 11b are correspondingly provided with fixing holes. The stepped shaft is inserted into the fixing holes so that the rotating shaft 12a is rotatably connected to the two side plates 11b.

Furthermore, the reagent container transporting device provided in the embodiment of the present invention further includes a locking device 40, at least a portion of which is connected to the bracket 11a of the fixing portion 11, and when the second slider 32 drives the fixing portion 11 to move to the second position along the guide rail 31 through the bracket 11a, the locking device 40 positions the fixing portion 11 to the second position to prevent the reagent container C from sliding down, and at this time, the reagent needle N begins to stably absorb the reagent in the reagent container C. When the fixing portion 11 continues to move a predetermined distance along the moving direction of the second slider 32, the locking device 40 releases the fixing portion 11.

As an optional embodiment, the locking device 40 is a miniature elastic bump bead, as shown in Figures 2 and 3, the miniature elastic bump bead includes a detachable bump bead 41 and a lock buckle 42, wherein the lock buckle 42 is fixed to the bracket 11a of the fixed part 11, and the bump bead 41 is fixed to a predetermined position relative to the lock buckle 42, and the bump bead 41 can lock or release the lock buckle 42.

Specifically, when the second slider 32 drives the fixed part 11 to move to the second position along the guide rail 31 through the bracket 11a, the ball 41 contacts and locks the lock 42, and makes a sound at the same time, reminding the operator that the reagent container C has reached the specified position. After the reagent needle N has absorbed enough reagent from the reagent container C, the operator operates the handle 13 to make the fixed part 11 continue to move a predetermined distance along the moving direction of the second slider 32, so that the ball 41 releases the lock 42 and unlocks it. As a result, the container seat 10 returns to the first position under the action of the second guide assembly 30 and the first guide assembly 20, and the accommodating part 12 is in an outwardly inclined state, so that the operator can easily take out the reagent container C from the accommodating part 12 and then replace the next reagent container C.

It is understandable that the locking device 40 is not limited to the micro elastic bump bead shown in the figure, and can also be other forms of micro elastic bump bead. For example, the entire structure of the micro elastic bump bead is connected to the bracket 11a of the fixed part 11. When the second slider 32 drives the fixed part 11 to move to the second position along the guide rail 31 through the bracket 11a, the micro elastic bump bead extends out of the lock buckle and connects with the hook plate set on the opposite side to achieve the locking function. The locking device 40 can also be other forms of locking structures, which will not be repeated here.

As an optional embodiment, the reagent container carrier device provided in the embodiment of the present invention further includes a damping device 50, which includes a gear 51 and a rack 52 that mesh with each other, the gear 51 being rotatably connected to the bracket 11a of the fixed part 11, and the rack 52 being arranged parallel to the guide rail 31. Since damping can be generated during the meshing of the gear 51 and the rack 52, when the operator operates the handle 13 to reciprocate the fixed part 11 between the first position and the second position, the fixed part can be stopped at any position within the travel of the guide rail 31 without having to operate the handle 13 all the time, thereby improving the user experience and facilitating the checking of the reagent status in the reagent container at any time.

It is understandable that the damping device 50 may also be a structure such as but not limited to an air spring, a coil spring, a guide device with damping, etc., which will not be described in detail here.

In addition, the reagent container carrier device proposed in the embodiment of the present invention further includes a fixed base 1, the needle tube of the reagent needle N has a first end close to the reagent needle N and a second end opposite to the first end, the second end can be movably clamped to the fixed fixed base 1, the first end is fixed with a flange 2, and a compression spring 3 sleeved on the outer side of the needle tube is arranged between the fixed base 1 and the flange 2. The reagent container C has an opening F, as shown in FIG1, when the fixing portion 11 of the container seat 10 reaches the second position, the opening F contacts the flange 2.

Specifically, the second end of the needle tube of the reagent needle N is provided with a retaining ring, and the fixed base 1 is provided with a through hole, through which the needle tube passes, and is clamped to the through hole by the retaining ring. The flange 2 can be welded to the reagent needle N at the first end of the needle tube, or fixed to the first end of the needle tube by other means. When the fixed portion 11 of the container seat 10 reaches the second position, the opening F of the reagent container C just contacts with the flange 2. The flange 2 drives the needle tube of the reagent needle N to be movable in the through hole of the fixed base 1 through the compression spring 3, so as to reduce the impact force when the opening F of the reagent container C just contacts with the flange 13 due to installation errors, etc.

In addition, when the needle of the reagent needle N is inserted from the opening F of the reagent container C below the liquid surface of the reagent to absorb the reagent, the compression spring 3 may be compressed due to slight disturbance, so that the reagent needle N will not be bent or damaged, thereby improving the reliability of the reagent container carrying device. When the reagent needle N absorbs enough reagent, the opening F of the reagent container C is out of contact with the flange 2, and the compression spring 3 returns to its original length.

In addition, the reagent container carrier device proposed in the embodiment of the present invention further includes a fixing frame 80, to which the slideway 21 in the first guide assembly 20, the guide rail 31 in the second guide assembly 30, the rack 52 in the damping device 50, and the fixing base 1 can be respectively fixed. If the first guide assembly 20 is a push rod, the push rod is also fixed to the fixing frame 80. It can be understood that the above-mentioned components can also be fixed to independent fixing frames respectively, depending on the specific application occasion.

Furthermore, the reagent container transport device provided in the embodiment of the present invention further includes a control device (not shown in the figure) and a position sensor 60. When the fixing portion 11 of the container seat 10 reaches the second position, the position sensor 60 can send an electrical signal to the control device to control the liquid path system connected to the reagent needle N to start sucking the reagent from the reagent container C. The position sensor 60 can be any one of a photoelectric sensor, an optical coupler or an electronic switch.

The reagent container carrier device provided in the embodiment of the present invention further includes a radio frequency module 70, which is electrically connected to the control device. A label containing the reagent information, such as a printed QR code, is provided on the outer surface of the reagent container C. The radio frequency module 70 scans the label and sends the reagent information to the control device to obtain the reagent information in the reagent container C.

Therefore, in the reagent container carrier provided according to the embodiment of the present invention, the first guide assembly 20 may be a slideway 21 including a first slideway portion 21a and a second slideway portion 22b arranged at a predetermined angle and a first slider 22 moving along the slideway 21. The first guide assembly 20 may also be a push rod arranged below the accommodating portion 12 to guide the accommodating portion 12 to drive the reagent container C to approach the reagent needle N so that the reagent needle N absorbs the reagent, or to flip outward when away from the reagent needle N so as to facilitate the placement of the reagent container C. In addition, when the fixing portion 11 reaches the second position, the locking device 40 is used to prevent the container seat 10 from sliding down. At this time, the flange 2 at the reagent needle N contacts the opening F of the reagent container C, and the impact force during the contact between the two is buffered by the compression spring 3, so that the reagent needle N can stably absorb the reagent in the reagent container C, thereby improving the reliability of the reagent container carrier.

Referring to FIG. 4 , an embodiment of the present invention further provides a reagent container transport system, comprising two or more transport devices 100 and a housing 200 arranged side by side.

The carrier 100 is the reagent container carrier as described above. The container seat 10 in the carrier 100 can reciprocate along the direction of the arrow shown in FIG. 4 under the guidance of the first guide assembly 20 and the second guide assembly 30 .

When the container seat 10 in the carrier 100 is close to the reagent needle N so that the reagent needle N absorbs the reagent in the reagent container C, the shell 200 can cover the outside of the container seat 10 to prevent the reagent in the reagent container C from being contaminated by impurities such as dust; the shell 200 is provided with an opening 210 in the direction of the container seat 10 away from the reagent needle N. When the reagent needle N absorbs enough reagent from the reagent container C, the container seat 10 is moved out of the shell 200 through the opening 210, so as to facilitate the replacement of the next reagent container C. Since the shell 200 does not need to cover the entire structure of the carrier 100, it occupies less space.

Furthermore, more than two carriers 100 are arranged side by side, for example, five carriers 100 may be arranged side by side, as shown in FIG4 . The reagent containers C in the five carriers 100 may contain reagents of different types or reagents of the same type, so that the operator can continuously take and place the reagent containers C without wasting time waiting for the reagent needle N to absorb the reagent and then replace it with a new reagent container C. Furthermore, the more than two carriers 100 work independently, so it is convenient to take and place the reagent containers C without interfering with each other, thereby further improving work efficiency.

In addition, a window 220 may be provided at the position of the housing 200 corresponding to the reagent needle N. If the number of carriers 100 is more than two, a corresponding window 220 is provided at the position of the reagent needle N of each carrier 100, that is, the number of windows 220 is the same as the number of carriers 100, so that the operator can check the remaining amount of reagent in each reagent container C in time when the containing portion 12 of each carrier 100 is close to the reagent needle N.

The reagent container transport system provided in the embodiment of the present invention improves the working efficiency of reagent sampling because it adopts the reagent container transport device as described above, and the number of the reagent container transport devices can be more than two.

Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
