Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a waste collection device, a pipetting device and a cup separating system.
Background
In chemical detection, pipetting is often involved. Pipetting means the transfer of material to be treated from one container to another. In many of the automated devices currently available, this can be accomplished by a pipette gun and a motion module. The motion module can drive the pipette to move. The pipette can be driven by the motion module to move to a designated position, so that pipetting and pipetting are completed.
Currently, some pipette guns on the market need to complete pipetting and priming by means of a matched gun head. In the scenes of virus detection and the like, in order to avoid interference and pollution, the pipette tip needs to be replaced once after each pipetting operation of the material by the pipette. Generally, the pipette gun is driven by the motion module to move to a designated station gun head, and after the pipetting operation is completed, the used gun head is discharged into the waste collection device.
However, some liquid remains on the tips discharged into the waste collection device. When the gun head is discharged, the gun head can collide with the bottom wall of the waste collection device to rebound, so that liquid is splashed. For some liquids with highly pathogenic bacterial or viral contamination, splattered liquids can cause contamination of related personnel and other materials.

However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the utility model by way of example only and that the utility model may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.
According to one aspect of the present utility model, a waste collection device is provided. The waste collection device may be used to collect waste. The waste collection device may be applied to a pipetting device. The pipetting device can be used for taking materials to be processed, uncovering, pipetting, closing the cover and the like. The pipetting device can be applied to a cup dispensing system. The waste collection device and pipetting device according to embodiments of the utility model are described in detail below in connection with specific embodiments.
As shown in fig. 1-4, the waste collection device 100 may have a cavity 200 therein. The volume and shape of the cavity 200 are not limited. The cavity 200 may be used to contain waste. Including but not limited to gun tips. The waste collection device 100 may be made of any suitable material such as acrylic sheet, metal sheet, or glass. The waste collection device 100 may be provided with an opening 300. The opening 300 may be communicated to the cavity 200. The number of openings 300 may be any number including, but not limited to, three as shown in the figures, such as one, two, or others.
A receiving member 400 may be disposed within the cavity 200. The number of receptacles 400 may be any number, including but not limited to one, two, or more. Illustratively, the pod 400 may be coupled to the walls of the cavity 200 by any suitable means, such as abutment, welding, or bonding. The pod 400 may have a pod interface 410. The receiving surface 410 may be disposed opposite the opening 300. Specifically, the receiving surface 410 is disposed obliquely with respect to the plane in which the opening 300 is located. That is, the receiving surface 410 may face the opening 300. The receiving surface 410 is neither perpendicular nor parallel to the plane in which the opening 300 lies. Illustratively, the plane in which the opening 300 lies may be a horizontal plane. The receiving surface 410 may be disposed obliquely with respect to the horizontal plane. So configured, the opening 300 may be disposed upwardly. The waste material is conveniently discharged into the cavity 200 through the opening 300.
In practical applications, the waste collection device 100 may collide with the receiving surface 410 of the receiving member 400 after the waste passes through the opening 300. Since the receiving surface 410 is disposed obliquely with respect to the plane of the opening 300, that is, the receiving surface 410 is neither parallel nor perpendicular with respect to the plane of the opening 300, the waste material will change the rebound angle after impinging on the receiving surface 410. Thus, the probability of the waste material popping back through the opening 300 is greatly reduced. In embodiments having liquid within the waste, the probability of liquid splashing out of the opening 300 is greatly reduced. In this way, the likelihood of contamination of personnel and other materials by liquids is greatly reduced.
Illustratively, in embodiments where the plane in which the opening 300 is located is a horizontal plane, the receiving surface 410 may slope downwardly from the edge of the cavity 200 toward the center. In this way, the upper edge of the receiving surface 410 may abut against the sidewall of the chamber 200. The lower edge of the receiving surface 410 may abut against the bottom wall of the cavity 200. In this way, the receiving member 400 does not cause dead angles in the cavity 200. In this way, the waste material may be facilitated to be dumped from the waste collection device 100.
Illustratively, as shown in fig. 5, in an embodiment of the waste collection device 100', the cavity 200 may have a centerline 900 in the depth direction. The depth direction is a direction perpendicular to the plane in which the opening 300 lies. At least a portion of the openings 300 may be disposed on both sides along the centerline 900. Illustratively, the openings 300 may be one, and at least a portion of one opening 300 may be disposed on both sides along the centerline 900. Illustratively, the openings may be a plurality and at least a portion of the plurality of openings 300 may be disposed along both sides of the centerline 900. The number of interfaces 410 may be two. Illustratively, two receptacles 410 may be provided on the same receptacle 400, or on respective receptacles 400. Two receiving surfaces 410 may be positioned below the openings 300 on either side of the centerline 900, respectively. So configured, waste material may drain into the cavity 200 along either side of the centerline 900. The waste material may be discharged into the cavity 200 through more locations. And, a plurality of wastes may be simultaneously discharged into the chamber 200. The waste collection device 100' has a high efficiency of collecting waste.
Only the differences between the waste collection device 100 'and the waste collection device 100 are described above, the same reference numerals are used for the same or similar components of the waste collection device 100' and the waste collection device 100, and for brevity, these same or similar components will not be described in detail herein.
Referring back to fig. 1-4, in embodiments where the opening 300 includes a plurality of openings 300, the plurality of openings 300 may be disposed parallel to one another. Thus, the size of the opening 300 is larger and the efficiency of the waste collection device 100 to collect waste is higher. In addition, the accumulation of waste material at one position in the cavity 200 can be prevented, and the utilization rate of the cavity 200 is high.
Illustratively, the waste collection device 100 may include a cassette 500 and a cover 600. The cover 600 may be covered to the case 500. The cover 600 may be detachably coupled to the case 500. Alternatively, the cover 600 may be non-detachably covered to the case 500 by welding or bonding, or the like, in any suitable manner. The case 500 and the cover 600 may enclose the cavity 200. The pod 400 may be disposed within the cartridge 500. The opening 300 may be provided on the cover 600. So configured, the garbage collection device 100 is simple in structure and low in manufacturing cost.
Illustratively, the cassette 500 may include a bottom panel 510 and side panels 520. The side plates 520 may extend upward from edges of the bottom plate 510, respectively. That is, the bottom of the side plate 520 may be connected to the bottom plate 510. The bottom panel 510 and the side panels 520 may surround to form the case 500. The cover 600 may be attached to the top of the side panels 520 by any suitable means, such as plugging, welding, or adhesive. Opposite sides of the base plate 510 may be provided with a first connection plate 710 and a second connection plate 720, respectively. The pod 400 may include a swash plate 800.

The upper edge of the swash plate 800 may abut the side plate 520. The surface of the swash plate 800 facing the opening 300 may form a receiving surface 410. So configured, the receiving member 400 can be relatively firmly secured within the cavity 200, thereby avoiding displacement under the impact of waste material.
Illustratively, the swash plate 800 may be provided at lower corners of opposite sides thereof with first and second notches 810 and 820, respectively. The first notch 810, the side plate 520, and the bottom plate 510 may be surrounded to form a first socket. The end of the first connection plate 710 may be plugged into the first socket. The second notch 820, the side plate 520, and the bottom plate 510 may be surrounded to form a second socket. An end of the second connection plate 720 may be plugged into a second socket. Thus, no dead space is generated in the cavity 200. In this way, the waste material may be facilitated to be dumped from the waste collection device 100.
In embodiments where the waste collection device 100 is applied to a pipetting device, the pipetting device may comprise a pipetting device and any of the waste collection devices 100 of the embodiments of the utility model. The pipetting device may be provided with a pipetting gun. Pipetting devices may perform pipetting and priming by a pipetting gun. After the pipette is used, the pipette needs to discharge the gun head of the pipette. At this point, the pipetting device may be moved to a position aligned with the opening 300. The pipetting device may then expel the gun head into the cavity 200 through the opening 300. In this way, the gun head is not easily ejected through the opening 300. Thereby preventing the liquid attached on the water-absorbing device from polluting related personnel and other materials.
Illustratively, in embodiments in which the opening 300 comprises a plurality of openings, the direction of extension of the plurality of openings 300 may be perpendicular to the direction of movement of the pipetting device. In this way, the pipetting device can be moved to any one of the openings 300 to discharge the tips, respectively. Thus, the gun head can be prevented from being piled up at one position in the cavity 200, and the utilization rate of the cavity 200 is high. And, the plurality of openings 300 also have a fool-proof function to prevent the installation direction of the garbage collection device 100 from being wrong.
