Description

Technical Field

[0001] This utility model relates to the field of eye drop research and development technology, and in particular to a rapid sampler for eye drop research and development. Background Technology

[0002] The rapid sampler for eye drop R&D is a device used to quickly obtain samples during the development of eye drops. It is mainly used to quickly, hygienically, and accurately extract and collect samples during the development, formulation screening, and quality testing of eye drops for component analysis, stability assessment, and process optimization.

[0003] When workers need to take samples from eye drop research and development samples, they bring the sampler into contact with the sample so that the sampler can take the sample. However, the existing samplers require workers to take samples manually during use, which may result in workers taking too many or too few samples, thus making it impossible for workers to quickly and quantitatively sample the samples. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that workers cannot quickly and quantitatively sample samples, and to propose a rapid sampler for eye drop research and development.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rapid sampler for eye drop research samples, comprising a sampling tube, a pipette at the bottom end of the sampling tube, a liquid level sensor inside the sampling tube, and a sampling device at the top end of the sampling tube. The sampling device includes a first motor, which is fixedly connected to the top end of the sampling tube. An impeller is fixedly connected to the drive end of the first motor, and the impeller is located inside the sampling tube. An exhaust port is provided at the top end of the sampling tube, located on one side of the impeller. A second motor is fixedly connected to the upper surface of the sampling tube, and a transmission rod is fixedly connected to the drive end of the second motor. The sampling tube is rotatably connected to its top end. A slider is threadedly connected to the surface of the conveying rod. A guide groove is provided inside the sampling tube. The slider is slidably connected to the inside of the guide groove. A sealing assembly is provided on the lower surface of the slider. The sealing assembly consists of a push rod, a sealing plug, and a partition plate. A partition plate is fixedly connected to the inner side of the sampling tube. The slider is located above the partition plate. A push rod is fixedly connected to the lower surface of the slider. The push rod is located inside the partition plate. The partition plate can cooperate with the sampling tube and the slider to achieve the purpose of blocking the sample. The hole groove on the inner side of the partition plate is larger than the outer diameter of the push rod. A handle is installed on the sampling tube. After sampling, the operator puts a partition sleeve on the pipette.

[0006] Preferably, a sealing plug is fixedly connected to the bottom end of the push rod. The sealing plug is located above the straw and can cooperate with the push rod to push the sealing plug to slide.

[0007] Preferably, the top end of the sampling tube is provided with a dustproof device, the dustproof device including a sealing ring, the sealing ring being fixedly connected to the top end of the sampling tube, the exhaust port being located inside the sealing ring, and the sealing ring being able to cooperate with the sampling tube to achieve the purpose of supporting the sealing ring.

[0008] Preferably, the inner side of the closed ring is threaded with a threaded ring, which is located on one side of the exhaust port. The threaded ring can cooperate with the closed ring to achieve the purpose of restricting the threaded ring.

[0009] Preferably, a sealing plate is fixedly connected to one side of the threaded ring. The sealing plate is placed on one side of the sealing ring and can cooperate with the threaded ring and the sealing ring to achieve the purpose of sealing the exhaust port.

[0010] Preferably, a rotating block is fixedly connected to one side of the sealing plate. The rotating block is located on one side of the sampling tube and can cooperate with the sealing plate to facilitate the worker in adjusting the rotation of the sealing plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a sampling device, when the worker needs to quickly sample the eye drop research samples, the worker starts the second motor, which drives the transmission rod. The transmission rod rotates and adjusts the slider. The slider is guided by the guide groove, rises and drives the push rod. The slider opens the inner side of the isolation plate, and the push rod drives the sealing plug. The sealing plug disengages from the pipette, and the first motor is started. The first motor drives the impeller, which rotates and draws air from inside the sampling tube. The air flows through the inner side of the isolation plate and is finally discharged from the exhaust port. The worker contacts the pipette at the bottom of the sampling tube with the sample. The negative pressure inside the sampling tube draws in the sample. When the sample reaches the set volume, the liquid level sensor controls the first motor to shut off, and the second motor adjusts the sealing plug to seal the pipette. The slider blocks the inner side of the isolation plate, and the worker puts the isolation cover on the pipette. By setting up the sampling device, the worker can effectively and conveniently sample the eye drop research samples quickly, avoiding the situation of taking too much or too little sample during the sampling process, thus facilitating the worker to quickly and quantitatively sample the sample.

[0012] 2. In this utility model, by setting a dustproof device, when the worker needs to prevent dust from entering the inside of the sampling tube, the worker places the threaded ring inside the closed ring, the worker rotates the rotating block, the rotating block drives the closed plate, the closed plate drives the threaded ring, the threaded ring is threadedly connected to the inside of the closed ring, and the closed plate is placed on the surface of the closed ring. By setting a dustproof device, the inside of the sampling tube can be effectively prevented from entering the inside when the sampler is idle, thereby reducing the situation of dust contaminating the sample.
