Its main task is to continuously provide more effective drugs and improve drug quality, ensure drug safety, and enable patients to treat or cure diseases in a way that minimizes harm and maximizes benefits. Pharmaceutical experiments are of great significance in the analysis process.

[0003] Referring to CN216525026U, a pharmaceutical experiment sampler is disclosed, which belongs to the technical field of pharmaceutical experiment devices.

[0004] However, the following problems still exist: during the sampling process, a straw is often used to take samples. After the straw is used to take samples, it is easy to touch the piston rod inside the straw, causing the internal pressure to cause the sampled medicine to flow out, affecting its use. Utility Model Content

[0005] The purpose of the utility model is to provide a pharmaceutical experiment sampler to solve the problem that in the sampling process, a straw is often used to extract samples. After sampling, the straw is easy to touch the piston rod in the straw, resulting in internal pressure and outflow of sampled medicine, which affects the use.

[0006] The technical solution adopted by the utility model is as follows: a pharmaceutical experiment sample extractor comprises a sample extracting cylinder, a sample extracting tube is fixedly connected to the lower surface of the sample extracting cylinder, a round pad is slidably sleeved on the inner wall of the sample extracting cylinder, a pull rod is fixedly connected to the upper surface of the round pad, a pull rod is fixedly connected to the top end of the pull rod, a pull plate is fixedly connected to the surface of the pull plate, a concave-convex plate is fixedly connected to the surface of the pull plate, a slider is fixedly connected to the surface of the concave-convex plate, a limit block is fixedly connected to the surface of the limit block, a connecting plate is provided on the side of the limit block, the inner wall of the connecting plate is adapted to the surface of the slider, a spring is slidably connected to the upper surface of the slider, a fixing rod is penetrated on the side of the spring, one end of the fixing rod is fixedly connected to an adapter plate, a fixing hole is provided on the inner wall of the connecting plate, and the fixing hole is adapted to the surface of the adapter plate.

[0007] By adopting the above technical scheme, the adapter plate is first pulled out of the fixed hole, and then the sampling tube is placed in the medicine to be sampled, and then the pull plate is pulled. The movement of the pull plate drives the pull rod to move, and the movement of the pull rod drives the round pad to move. The round pad moves and draws the medicine into the sampling tube through the sampling tube for sampling. When the pull plate moves up, it drives the concave-convex plate up, and the concave-convex plate drives the slider up, and the slider drives the fixed rod up. When the sampling is completed, the spring is released, and the spring resets and pushes the moving plate to move. The moving plate moves and drives the adapter plate into the fixed hole through the fixed rod, which solves the problem of accidentally touching the pull plate during use, causing the round pad to move down and squeeze out the sample in the sampling tube.

[0008] In a preferred embodiment, a top cover is fixedly connected to the inner wall of the sample extraction cylinder, and an air outlet is provided on the upper surface of the top cover.

[0009] By adopting the above technical solution and providing the air outlet hole, when the round pad is pulled, the gas above the round pad can be discharged to the outside, allowing the sample tube to absorb the medicine.

[0010] In a preferred embodiment, a vertical plate is fixedly connected to the upper surface of the sliding block, a sliding rod is fixedly connected to the side surface of the vertical plate, and the sliding rod is passed through the side surface of the moving plate.

[0011] By adopting the above technical solution and arranging the vertical plate, the sliding rod can be used to move on the upper surface of the sliding block when the moving plate is pushed.

[0012] In a preferred embodiment, a baffle is fixedly connected to the upper surface of the sliding block, a spring is fixedly connected to the side of the baffle, and one end of the spring away from the baffle is fixedly connected to the side of the moving plate.

[0013] By adopting the above technical solution and arranging a spring, the movable plate can be reset to move, thereby driving the fixing rod and the adapter plate to move into the fixing hole.

[0014] In a preferred embodiment, one end of the fixing rod away from the baffle is fixedly connected to a handle, and the upper surface is fixedly connected to a handle.

[0015] By adopting the above technical solution and providing a pull handle, it is convenient for the user to pull the fixing rod to move, and the movement of the fixing rod drives the adapter plate away from the fixing hole to cancel the fixation.

[0016] In a preferred embodiment, the round pad is made of rubber.

[0017] By adopting the above technical solution, the material of the round pad is set to be rubber, which has elasticity and fits on the inner wall of the sample extraction tube to increase air tightness.

[0018] In a preferred embodiment, the number of the fixing holes is multiple.

[0019] By adopting the above technical solution and setting the number of fixing holes to be a certain number, the slider can be fixed at any time by the adapter plate according to the sliding position of the slider.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] 1. In the utility model, the adapter plate is first pulled out from the fixed hole, and then the sampling tube is placed in the medicine to be sampled, and then the pull plate is pulled. The movement of the pull plate drives the pull rod to move, and the movement of the pull rod drives the round pad to move. The round pad moves through the sampling tube to draw the medicine into the sampling tube for sampling. When the pull plate moves up, it drives the concave-convex plate up, and the concave-convex plate drives the slider up, and the slider drives the fixed rod up. When the sampling is completed, the spring is released, and the spring resets at this time to push the moving plate to move. The moving plate moves and drives the adapter plate to move into the fixed hole through the fixed rod, which to a certain extent solves the problem of accidentally touching the pull plate during use, causing the round pad to move down and squeeze out the sample in the sampling tube.
