Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling equipment technology, and more specifically, to a sampling device for pharmaceutical testing. Background Technology
[0002] Pharmaceutical testing refers to the process of systematically evaluating a drug's pharmacological effects, pharmacokinetic characteristics, safety, and clinical efficacy through laboratory studies, animal experiments, and human trials during the drug development cycle. The selection of sampling equipment for pharmaceutical testing must take into account sample characteristics, trial scale, and regulatory compliance.
[0003] In pharmaceutical experiments, manual sampling of drugs is required. Most drugs are stored in sealed containers to prevent loss of efficacy and contamination. Existing sampling equipment mostly uses syringes for direct manual extraction, taking quantitative amounts according to the experimental requirements. However, syringe extraction is inconvenient, yields small sample volumes, and excessively fast aspiration can cause air bubbles. Therefore, we propose a sampling device for pharmaceutical experiments. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a sampling device for pharmaceutical testing to solve the technical problems of inconvenient manual extraction, easy generation of air bubbles, and small single sampling volume of the current sampling device.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sampling device for pharmaceutical testing, comprising a clamping mechanism, a connecting cover, a bottom cylinder, a turntable, and an adjusting component. Insert plates are fixed to both sides of the lower end of the connecting cover, and the insert plates are inserted into the inner side of the bottom cylinder. A sampling bottle is installed inside the bottom cylinder. The clamping mechanism is installed on the upper side of the connecting cover and is composed of an outer ring. Adjustment ports are provided on both sides of the outer ring, and positioning ports are provided at both ends of the openings of the adjustment ports. The turntable is located within a recess on the upper side of the outer ring, and inclined pressure ports are provided on both sides of the turntable. The adjusting component is fixed to the lower inner side of the outer ring.
[0006] After assembly, the sampling bottle is placed inside the bottom cylinder, and then the device is pressed. During the pressing process, the insert plate and the bottom cylinder retract, at which point the sampling tube of the sampling bottle is inserted through the perforation. When the cap presses the lifting plate to retract towards the connecting cap, the sampling tube is then inserted into the sealing rubber stopper of the bottom end cap of the storage dish, placing the sampling tube inside the storage dish. The solution in the storage dish enters the sampling bottle through the sampling tube to complete the sampling. The amount is determined by the scale on the outside of the sampling bottle. Through the two-stage compression structure described above, the device performs sampling in an insertion manner. After sampling, the sampling tube can be separated, reducing the difficulty of operation and ensuring safety during the sampling process. The device maintains a sealed connection to prevent leakage of the sampled liquid and ensure safety. During installation, the storage dish needs to be placed inside the outer protective plate, with the end cap opening at the bottom of the storage dish inserted into the inlet. Then, manually pull the pull ring to unfold the elastic connection with the traction block, separating the pull ring from the positioning port. Then, slide the traction block to drive the turntable to rotate 90 degrees. At this time, the inclined pressure port squeezes the synchronous rod, causing the distance between the two clamping parts to decrease. At this time, the clamping parts hold and fix the end cap at the inlet, thus fixing the storage dish. Through the above structural design, this device facilitates the assembly of the storage dish and reduces the difficulty of operation. Then, rotate the locking mechanism to fix the storage dish, which is convenient for subsequent operations.
[0007] Preferably, a return spring is fixed on both sides of the inside of the bottom cylinder, and the upper end of the return spring is fixed to the lower end of the insert plate. A limit groove is opened on the outer side of the insert plate, and a limit block is fixed on the upper end of both sides of the inside of the bottom cylinder, and the limit block is slidably installed in the corresponding limit groove.
[0008] Preferably, the sampling bottle has a scale on the front side and is made of glass. The upper end of the sampling bottle is fixed with a cap, and a sampling tube is installed through the middle of the upper end of the cap.
[0009] Preferably, the connecting cover has an insertion port in the middle, and a lifting plate is slidably installed in the lower recess of the connecting cover, with the lifting plate corresponding to the bottom cylinder. The connecting cover and the lifting plate are connected by a top pressure spring. The lifting plate has a through hole in the middle, and the sampling tube is adapted to the through hole.
[0010] Preferably, traction blocks are fixed on both sides of the turntable, and the traction blocks are slidably installed in the adjustment port. A pull ring is installed on the outer end of the traction block through a spring-loaded assembly, and the rear end of the pull ring is inserted and limited in the positioning port.
[0011] Preferably, the turntable has an adapter port in the middle, and the inner opening, through hole, insertion port and adapter port of the outer ring correspond to each other.
[0012] Preferably, the adjustment assembly consists of a fixing ring and a clamping member. The fixing ring has movable grooves on both sides of the internal opening. The clamping member has a Y-shaped structure design, and the two clamping members clamp and fix the end cap opening of the storage dish.
[0013] Preferably, the rear end of the clamping member is slidably installed in the movable groove, a synchronizing rod is fixed on the upper end face of the clamping member, and the synchronizing rod is inserted into the inclined pressure port, and a protective pad is fixed on the arc-shaped opening of the clamping member.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model, through the design of the bottom cylinder, allows the sampling bottle to be placed inside the bottom cylinder after assembly. Pressing the device causes the insert plate and bottom cylinder to retract, allowing the sampling tube of the sampling bottle to be inserted through the perforation. When the cap presses the lifting plate to retract towards the connecting cap, the sampling tube is inserted into the sealing rubber stopper of the bottom end cap of the storage dish, placing the sampling tube inside the storage dish. The solution in the storage dish enters the sampling bottle through the sampling tube to complete the sampling. The amount is determined by the scale on the outside of the sampling bottle. Through the two-stage compression structure described above, this device performs sampling via insertion. After sampling, a separation stage allows for the separation of the sampling tube, reducing operational difficulty. Maintaining a sealed connection during sampling prevents leakage of the sampled liquid and ensures safety.
[0016] 2. This utility model also incorporates a clamping mechanism. During installation, the storage dish needs to be placed inside the outer protective plate, with the end cap opening at the bottom of the storage dish inserted into the inner side of the insertion port. Then, manually pull the pull ring to unfold the elastic connection between it and the traction block, separating the pull ring from the positioning port. Then, slide the traction block to drive the turntable to rotate 90 degrees. At this time, the inclined pressure port squeezes the synchronous rod, causing the distance between the two clamping parts to decrease. At this time, the clamping parts clamp and fix the end cap at the insertion port to fix the storage dish. Through the above structural design, this device facilitates the assembly of the storage dish and reduces the difficulty of operation. Then, the rotating locking mechanism fixes the storage dish, facilitating subsequent operations. Attached Figure Description
