DETAILED DESCRIPTION

[0022] The following embodiments will be combined with the accompanying drawings to describe the utility model in detail. In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component can be enlarged or reduced. The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0023] See also Figure 1-5 As shown, the utility model proposes a precise metering dispensing device for biomedical research, comprising a mixing tank 4 and an operating component 1 mounted on the top of the mixing tank 4, and a metering component 2 mounted on the operating component 1, wherein the operating component 1 comprises a fixed plate 103 fixedly mounted on the top of the mixing tank 4, a movable column 102 is slidably mounted at the center of the fixed plate 103, and medicine storage tanks 3 distributed in an annular array are fixedly mounted on the outer side of the fixed plate 103, the metering component 2 comprises a collecting cylinder 5 fixedly mounted on the fixed plate 103 and located on the outer side of the movable column 102 in an annular array, and a fixed column 205 fixedly mounted on the fixed plate 103 and located on the outer side of the collecting cylinder 5 in an annular array, a piston rod 501 extending from the top is movably mounted inside the collecting cylinder 5, the piston rod 501 and the movable column 102 are slidably mounted via a slider 502, a sliding sleeve 201 is slidably mounted on the outer side of the fixed column 205, and a limiting block 202 used in conjunction with the slider 502 is fixedly mounted on one side of the sliding sleeve 201.

[0024] Based on the above-mentioned structural setting, the precise metering type biomedical research dispensing device is composed of a mixing tank 4, an operating component 1, a metering component 2 and a medicine storage tank 3, wherein the metering component 2 can be used to conveniently and independently meter a plurality of drugs, the operating component 1 can be used to perform metering operation on the metering component 2, the drugs in a plurality of medicine storage tanks 3 can be measured and extracted separately through a one-time operation, and at the same time, the extracted drugs can be uniformly introduced into the mixing tank 4 for mixing operation through the operating component 1. Specifically, in the working process, by providing a plurality of medicine storage tanks 3, a plurality of drugs required for medical research can be conveniently stored. When metering, the sliding sleeve 201 can slide up and down along the fixed column 205, and the height position of the limit block 202 can be conveniently adjusted. The limit block 202 can be adjusted to a specified height according to the metering requirements, which can conveniently limit the moving height of the piston rod 501, and by pulling the movable column 102 to move upward, a plurality of movable columns 102 can be driven at the same time. When the stopper rod 501 moves upward, the interior of the collecting tube 5 is in a negative pressure state, which can facilitate the suction of the medicine in the medicine storage tank 3 into the corresponding collecting tube 5 through the delivery tube 302. The piston rod 501 can only move to a specified position through the limit block 202, so that the amount of medicine in the medicine storage tank 3 sucked into the collecting tube 5 can be conveniently controlled. The slider 502 can slide along the surface of the movable column 102. By setting a plurality of limit blocks 202 at different heights, the movable column 102 can be moved upward. Multiple piston rods 501 can be driven to move to different heights at the same time, so that different types of medicines can be quantitatively sucked into the collecting tube 5 in one operation. When the movable column 102 is pressed to move downward, multiple piston rods 501 can be pressed downward at the same time, so that the medicines in the collecting tube 5 can be simultaneously introduced into the mixing tank 4 for mixing, which effectively saves the dispensing time and improves the work efficiency.

[0025] Furthermore, a lifting handle 101 is fixedly installed on the top of the movable column 102, and a slide groove 104 is provided on the outer side of the movable column 102 in a circular array and used in conjunction with the slider 502. The lifting handle 101 can be used to facilitate the up and down movement of the movable column 102, and the slide groove 104 can limit the slider 502, so that the slider 502 can slide up and down along the slide groove 104 without falling off.

[0026] Furthermore, a tension spring 503 is fixedly installed between the slider 502 and the movable column 102, and the collecting cylinder 5 and the mixing tank 4 are connected to each other through the conduit 504. When the movable column 102 moves upward, the slider 502 can be pulled upward by the action of the tension spring 503. When the slider 502 contacts the stop block 202, the slider 502 can be blocked from continuing to move. At the same time, the movable column 102 can continue to move upward, and can drive the remaining sliders 502 to continue to move upward, so as to facilitate driving multiple piston rods 501 to move to different heights at the same time. When the piston rod 501 moves downward, the medicine in the collecting cylinder 5 can be introduced into the mixing tank 4 through the conduit 504.

[0027] Furthermore, the sliding sleeve 201 is fixed to the fixed column 205 by a fixing bolt 203, and a scale line 204 is engraved on the surface of the fixed column 205. The sliding sleeve 201 can be fixed to a suitable position on the fixed column 205 by the fixing bolt 203, and by observing the value on the scale line 204, the limit block 202 can be conveniently moved to a specified height according to the amount of measurement, so as to conveniently control the moving height of each piston rod 501, and the amount of medicine sucked into the collecting tube 5 can be accurately controlled.

[0028] Further, the medicine storage tank 3 is fixedly installed with the fixing plate 103 via the fixing frame 301, and the fixing frame 301 is fixedly connected with the medicine storage tank 3. The fixing frame 301 can fix the medicine storage tank 3, so that the medicine storage tank 3 is not easy to fall off.

[0029] Furthermore, a one-way valve 303 is installed on the delivery tube 302. When the piston rod 501 moves upward, the one-way valve 303 can be opened by utilizing the negative pressure in the collection tube 5, so that the medicine in the medicine storage tank 3 can be sucked into the collection tube 5 through the delivery tube 302. When the piston rod 501 moves downward, the one-way valve 303 can be closed, so that the medicine in the collection tube 5 can be prevented from flowing back into the medicine storage tank 3.
