Technical Field
[0001] This utility model relates to the technical field of flow cytometer equipment, specifically to a waste liquid collection device for flow cytometers. Background Technology
[0002] Flow cytometers are important analytical instruments in the life sciences field, widely used in cell biology, immunology, and other research. During operation, they generate a large amount of waste liquid, which may contain chemical reagents, biological samples, and other components. If not properly collected and treated, this waste liquid can not only contaminate the laboratory environment but also affect the normal operation of the instrument and the accuracy of the test results.
[0003] Currently, traditional flow cytometer waste collection devices have significant shortcomings. First, they lack a waste transfer function, requiring the machine to be stopped for replacement when the collection container is full. Second, there is a risk of residual liquid dripping and contaminating the storage environment during container replacement. Therefore, we propose a waste collection device for flow cytometers.

[0022] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 This utility model proposes a waste liquid collection device for flow cytometers, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a transfer chamber 3 placed on the top of the support frame 2, a discharge hole 4 at the bottom of the transfer chamber 3, a discharge pipe 5 fixedly connected to the bottom of the discharge hole 4, and a manual butterfly valve installed on the discharge pipe 5. The butterfly valve is opened and closed by rotating the handle to drive the valve disc to rotate. The rotation angle of the handle is linearly related to the opening degree of the valve disc. When the handle is rotated to 90°, the valve disc is fully opened, and the waste liquid can be discharged smoothly through the discharge pipe 5. When the handle is rotated to 0°, the valve disc is tightly attached to the inner wall of the pipe, blocking the flow of waste liquid. The operation is simple and the sealing is good. A waste liquid collection cup 6 is placed on the top of the base 1, and a collection cup cover 7 is threadedly connected to the top of the waste liquid collection cup 6. A pipe hole 8 is opened on the collection cup cover 7, and a sliding sleeve 9 is fixedly connected to the top of the pipe hole 8. The discharge pipe 5 can slide into the sliding sleeve 9. A lifting component 10 is provided on the base 1.
[0025] In this utility model, the lifting assembly 10 includes a guide sleeve 101, a guide rod 102 is slidably connected to the inner wall of the guide sleeve 101, and a lifting plate 103 is fixedly connected to the top of the guide rod 102. The guide sleeve 101 guides the movement of the guide rod 102, thereby guiding the lifting of the lifting plate 103. A working placement slot is provided on the lifting plate 103, and an idle placement slot is provided on the top of the base 1. The working waste liquid collection cup 6 is placed in the working placement slot, and a spare waste liquid collection cup 6 is placed in the idle placement slot. The waste liquid collection cup 6 is made of glass, which makes it convenient to observe the liquid level inside.
[0026] Furthermore, a threaded sleeve 104 is fixedly connected to the inner wall of the base 1. A threaded through hole is provided on the threaded sleeve 104, and an adjusting rod 105 is threadedly connected to the threaded through hole. The adjusting rod 105 is provided with a partial thread, and the partial thread is located in the middle of the adjusting rod 105. The adjusting rod 105 is supported by the threaded sleeve 104.
[0027] Furthermore, one end of the adjusting rod 105 is fixedly connected to the adjusting disc 106, and the other end of the adjusting disc 106 is fixedly connected to the elliptical disc 107. By rotating the adjusting disc 106, the adjusting rod 105 is driven to rotate and move on the threaded sleeve 104, thereby causing the elliptical disc 107 to move synchronously. Since the lifting plate 103 abuts against the outer wall of the elliptical disc 107 under the action of gravity, the rotation of the elliptical disc 107 can change the height of the lifting plate 103, thereby changing the height of the working waste liquid collection cup 6, so that the sliding sleeve 9 on the cup is separated from the discharge pipe 5.
[0028] Furthermore, an extension rod 11 is fixedly connected to the bottom of the transfer compartment 3, and a snap-fit rod 12 is snapped into the inner wall of the extension rod 11. A snap-fit groove is provided on the extension rod 11, and the snap-fit rod 12 is snapped into the snap-fit groove. A hemispherical hole is provided on the snap-fit rod 12.
[0029] Furthermore, a sliding T-bar 13 is slidably connected to the bottom of the extension rod 11, and a liquid receiving plate 14 is fixedly connected to the outer wall of the snap-fit rod 12. A sliding hole is provided on the extension rod 11, which communicates with the snap-fit groove. The sliding T-bar 13 and the extension rod 11 are elastically connected by a spring. The top of the sliding T-bar 13 is hemispherical and can slide into the hemispherical hole. A drip collection groove is provided on the liquid receiving plate 14 to collect the drips.
[0030] Furthermore, the top of the transfer chamber 3 is threadedly connected to a chamber cover 15, which has a placement through hole. The waste liquid conduit of the flow cytometer can enter the transfer chamber 3 through the placement through hole. Rotating the chamber cover 15 also facilitates the periodic cleaning of the transfer chamber 3.
[0031] When in use, when the waste liquid collection cup 6 is close to full, rotate the manual butterfly valve handle to 0° to close the butterfly valve, so that the discharge pipe 5 stops discharging and the waste liquid is temporarily stored in the transfer chamber 3.
[0032] Rotate the adjusting disc 106, which drives the adjusting rod 105 to rotate on the threaded sleeve 104. The elliptical disc 107 moves synchronously, causing the lifting plate 103 to descend. The waste liquid collection cup 6 that is working moves downward accordingly, and the discharge pipe 5 separates from the sliding sleeve 9.
[0033] Pull out the liquid receiving plate 14, so that the sliding T-bar 13 is disengaged from the hemispherical hole of the clamping rod 12. Rotate the liquid receiving plate 14 and reinsert it into the extension rod 11 so that it is located below the discharge pipe 5 to receive the residual waste liquid.
[0034] Remove the nearly full waste liquid collection cup 6 and place the spare waste liquid collection cup 6 from the idle placement tank into the working placement tank of the lifting plate 103.
[0035] Rotate the adjusting plate 106 again to raise the lifting plate 103, which will move the spare waste liquid collection cup 6 upward until the discharge pipe 5 slides into the sliding sleeve 9 of the collection cup cover 7, thus completing the replacement of the collection cup. Then, the manual butterfly valve handle can be rotated to 90° to restore the normal waste liquid collection process.
[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
