Description

Technical Field

[0001] This utility model relates to the field of drug sampling technology, specifically a sampling device for drug analysis. Background Technology

[0002] Pharmaceutical analysis refers to the use of chemical, physical, biological, and microbiological methods and techniques to study the quality of synthetic or natural drugs and their preparations with well-defined chemical structures. In pharmaceutical analysis experiments, whether it is the testing of finished drugs or raw materials, drug sampling is a necessary procedure. During the operation of drug sampling and analysis, the laboratory personnel need to use sampling devices.

[0003] Currently, fluid drugs are usually sampled using sampling tubes or droppers and then dripped into test tubes. However, the sampling volume of fluid drugs using sampling tubes and droppers is relatively small. This means that when conducting large-scale sampling tests on a certain fluid drug, repeated sampling is required, and only one bottle can be dripped at a time, resulting in low sampling efficiency and reducing the work efficiency of fluid drug sampling.

[0004] Therefore, there is an urgent need for a sampling device for drug analysis to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 The figure shows a sampling device for drug analysis, including a sampling box 1 and a sampling component disposed in the sampling box 1 for sampling liquid drugs.

[0021] The sampling assembly includes an arc-shaped plate 201 fixedly connected to the inner wall of the sampling box 1, and U-shaped plates 202 fixedly connected to both ends of the arc-shaped plate 201. Sampling tubes 203 are provided inside the arc-shaped plate 201 and the two U-shaped plates 202. The sampling box 1 is provided with a compression assembly for reciprocating compression of the sampling tubes 203.

[0022] It should be noted that, through the design of the sampling components, the combined action of the squeezing, connecting, and telescopic components, the sampling of liquid drugs is achieved while ensuring sufficient sample volume and improving the efficiency of sampling large-dose samples, thereby increasing the efficiency of fluid drug sampling.

[0023] Please see Figure 1 and Figure 2 The sampling tube 203 shown in the figure has both ends passing through the sampling box 1 and is connected to the extension tube 205 through the locking connector 204.

[0024] It should be noted that the locking connector 204 and the extension tube 205 make it easy to select the appropriate extension tube 205 according to the length of the container holding the liquid medicine, thereby improving the sampling flexibility of liquid medicine in containers at different depths.

[0025] Please see Figure 2 and Figure 3 The extrusion assembly shown in the figure includes a rotating rod 301 rotatably connected to the sampling box 1. The side wall of the rotating rod 301 is connected to extrusion balls 302 through multiple connecting components. The extrusion balls 302 are arranged in a ring array.

[0026] It should be noted that, through the arrangement of the extrusion assembly, the rotation of the rocker wheel 304 will drive the rotating rod 301 on the mounting rod 303 to rotate. During the rotation of the rotating rod 301, the extrusion balls 302 will rotate through the various connecting components. When one of the extrusion balls 302 comes into contact with the sampling tube 203 located in the arc plate 201 under the elastic action of the telescopic assembly, the sampling tube 203 will deform from the point of contact due to the pressing action of the extrusion ball 302. As the extrusion ball 302 continues to rotate, it will push the liquid medicine in the sampling tube 203 towards the sampling bottle, thereby realizing the sampling operation of the liquid medicine.

[0027] Please see Figure 1 The sampling box 1 in the figure is rotatably connected between the two inner walls by an installation rod 303. The rotating rod 301 is fixedly connected to the side wall of the installation rod 303. One end of the installation rod 303 passes through the sampling box 1 and is fixedly connected to a rocker wheel 304.

[0028] It should be noted here that the rocker wheel 304 facilitates the rotation of the rotating rod 301.

[0029] Please see Figure 2 and Figure 3 The connecting assembly shown in the figure includes a connecting pipe 401 fixedly connected to the side wall of the rotating rod 301. The connecting pipe 401 is connected to a connecting rod 402 through a telescopic assembly. The end of the connecting rod 402 away from the rotating rod 301 is connected to the extrusion ball 302.

[0030] It should be noted here that the connection components are designed to provide extension and guidance for the movement of the extrusion ball 302.

[0031] Please see Figure 2 and Figure 3 The telescopic assembly shown in the figure includes a telescopic plate 501 slidably connected to the connecting pipe 401, a connecting rod 402 with one end away from the extrusion ball 302 connected to the telescopic plate 501, and a spring 502 sleeved on the inner side wall of the connecting rod 402 inside the connecting pipe 401. The two ends of the spring 502 are respectively connected to the telescopic plate 501 and the inner wall of the connecting pipe 401.

[0032] It should be noted here that the telescopic component ensures that the compression ball 302 fully compresses the sampling tube 203.

[0033] Working principle: When it is necessary to sample liquid medicine, first select an appropriate extension tube 205 according to the length of the container holding the liquid medicine, and connect it to the sampling tube 203 through the locking connector 204. After connecting the two ends of the extension tube 205 and the sampling tube 203 in the second round, insert one of the two extension tubes 205 into the container holding the liquid medicine, and put the other into the sampling bottle.

[0034] Then, the rocker wheel 304 is rotated, and the rotation direction of the rocker wheel 304 is closer to the sampling bottle. During the rotation of the rocker wheel 304, the rotating rod 301 on the mounting rod 303 will be driven to rotate. During the rotation of the rotating rod 301, the squeezing ball 302 will be driven to rotate through the various connecting components. During the rotation of the squeezing ball 302, when one of the squeezing balls 302 abuts against the sampling tube 203 located in the arc plate 201 under the elastic action of the telescopic component, the sampling tube 203 will deform from the abutting point under the pressing action of the squeezing ball 302. As the squeezing ball 302 continues to rotate, it will push the liquid medicine in the sampling tube 203 to be transported towards the sampling bottle.

[0035] The sampling tube 203, after being squeezed by the squeeze ball 302, will recover under its own deformation capacity. During the recovery process, due to the pressure difference, the liquid drug in the container will be drawn into the sampling tube 203. At this time, another squeeze ball 302 will squeeze the sampling tube 203 again, thereby transporting the liquid drug in the sampling tube 203 to the sampling bottle. Therefore, as each squeeze ball 302 reciprocates to squeeze the sampling tube 203, the liquid drug in the container will be continuously transported to the sampling bottle. This achieves liquid drug sampling while ensuring sufficient sample volume and improving the efficiency of sampling large doses of samples, thereby improving the working efficiency of fluid drug sampling.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
