Description

Technical Field

[0001] This utility model belongs to the field of culture medium dispensing technology, and in particular relates to a culture medium dispenser. Background Technology

[0002] In the field of molecular biology, the transfer and dispensing of culture media is a common and important operation. Traditional media dispensing methods often have several drawbacks. On the one hand, the control of dispensing volume is not precise enough, usually relying on the operator's experience and manual operation, making it difficult to ensure that the amount of media dispensed each time is consistent. For some molecular biology experiments with strict requirements on the amount of media used, this may lead to inaccurate and non-reproducible experimental results. On the other hand, the operation process is relatively cumbersome and inefficient, requiring operators to concentrate for a long time on dispensing, which can easily lead to fatigue and further increase the risk of inaccurate dispensing volumes.

[0003] Therefore, developing a culture medium dispenser that can accurately dispense quantitatively, is easy to operate, highly adaptable, and hygienic is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to provide a culture medium dispenser that achieves precise quantitative dispensing through a peristaltic pump and a trigger switch. The components are reasonably designed, have strong adjustable angle adaptability, and emphasize hygiene and safety.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0012] This utility model has the following beneficial effects:

[0013] This invention features a peristaltic pump with quantitative measurement capabilities. A fixed output volume can be preset for each start-up. During the dispensing and pipetting process, pressing the trigger switch causes the peristaltic pump to pump according to the preset volume. Once the volume reaches the set value, the pump automatically stops, ensuring a stable and consistent volume of culture medium dispensed each time, thus meeting the precise dispensing requirements of molecular biology experiments.

[0014] This invention uses a trigger switch to control the start and stop of the peristaltic pump. Operators only need to manually touch the trigger switch to start the peristaltic pump for dispensing and pipetting, which is simple and convenient to operate and improves dispensing efficiency.

[0015] The rectangular base, rectangular upright plate, and rectangular plate structure of the fixed frame of this utility model, as well as the rectangular block and through hole, stepped through hole, and other designs of the dispensing conduit mounting seat, enable the dispensing conduit mounting seat to be stably installed on the fixed frame, and make installation and disassembly convenient.

[0016] This invention utilizes the semi-circular groove at the upper end of the rectangular plate and the cylindrical heads on both sides of the middle of the rectangular block of the dispensing tube mounting seat, along with the through hole design of the fan-shaped structure, to allow the angle of the dispensing tube mounting seat to be adjusted, thereby adjusting the tilt angle of the dispensing tube. This enables it to adapt to different sizes of storage containers used for dispensing culture media, improving the versatility of the dispenser.

[0017] The L-shaped tube design of the aspiration tube of this utility model has a first limiting ring at the corner for easy handling, and a C-shaped groove on the lower end wall to prevent it from sealing with the culture medium storage bottle, thus facilitating the aspiration of the culture medium; the outer wall of the upper end of the round tube of the dispensing tube is fixed with a second limiting ring to ensure the stability of the dispensing tube after it is inserted into the dispensing tube mounting base.

The above-mentioned functions of the peristaltic pump 1 are existing functions and will not be described in detail here.

[0031] The aspiration conduit 4 includes an L-shaped tube body 41. A first limiting ring 42 is provided on the tube wall at the corner of the L-shaped tube body 41 to facilitate the handling of the aspiration conduit 4. A C-shaped groove 43 is opened on the lower end wall of the L-shaped tube body 41 to prevent the lower end of the L-shaped tube body 41 from sealing with the culture medium storage bottle, facilitating the aspiration of culture medium at the lower end of the conduit 4. The dispensing conduit 5 includes a circular tube body 51. A second limiting ring 52 is fixed on the outer wall of the upper end of the circular tube body 51. The second limiting ring 52 is positioned above the stepped through hole 73 to ensure the stability of the dispensing conduit 5 after insertion.

[0032] The fixed frame 6 includes a rectangular base 61. A rectangular upright plate 62 is fixed to the upper surface of one end of the rectangular base 61. Two parallel rectangular plates 63 are vertically fixed to the upper end of the rectangular upright plate 62. The two rectangular plates 63 have oblong through holes 64 in the middle of their sides, extending along their length. Bolts and nuts 8 pass through the oblong through holes 64 and are clamped onto the two rectangular plates 63.

[0033] The sub-conduit mounting base 7 includes a rectangular block 71. A horizontal through hole 72, which mates with bolts and nuts 8, is formed in the center of the rectangular block 71.
