Description

Technical Field

[0001] The utility model relates to the technical field of laboratory sampling, in particular to a disposable sampler. Background Art

[0002] Currently, the longest size of solid sample containers used in pharmaceutical analysis laboratories is 2.5ml and 4ml container bottles or test tubes of their size. Commonly used solid powder samplers usually include a handheld part and a sampling part connected to the handheld part, and the sampling part is usually in the shape of a spoon.

[0003] Existing samplers have the following disadvantages:

[0004] ① Unable to take out all the samples. When there are more samples in the container bottle or test tube, the samples can be taken out smoothly. However, when there are few samples left, it is impossible to take out all the samples. Then you can only dump the container bottle or test tube and pour the sample into the sampler, which is easy to spill the material. For rare or expensive samples, it will cause great waste. In particular, due to the special structure of the test tube, the commonly used sampler cannot take out all the samples at the bottom of the test tube; and some of the samples in the container bottle or test tube will stick to the inner wall of the container bottle, and the rod of the sampling part and the handheld part cannot scrape off the powder on the side wall, which will again cause the phenomenon that although there is a sample in the container bottle, it cannot be effectively taken out.

[0005] ② During the transfer process, the sample is easily scattered. In the existing solid powder sampler, only the sampling part can hold the sample, and the handheld part does not have the holding capacity. Therefore, the sample in the sampling part is easily scattered during the transfer process, resulting in waste.

[0006] ③ Corresponding to different sizes of container bottles or test tubes, the sampler needs to be designed separately. It is not possible to make a single sampler adapt to both container bottles or test tubes. If the sampler structure is set to a small size, although it can be used to sample large and small container bottles or test tubes, the number of samples taken each time is too small and the rigidity is limited. If the sampler size is too large, it cannot be inserted into the small container bottle for sampling. Therefore, separate designs are usually used for container bottles or test tubes of different sizes, so that each sampler is used for each container, which causes great inconvenience.

[0007] ④ Most existing samplers are non-disposable. Therefore, after taking one sample, they must be cleaned and sterilized before taking another. This cumbersome process increases sampling time. Non-disposable samplers are expensive to prepare, and if each sample is equipped with a sampler, the cost will increase further. Furthermore, all samplers need to be cleaned and sterilized uniformly during each experiment, which still does not solve the cumbersome use problem.

[0008] In summary, a new sampler is needed to solve the above technical problems. Utility Model Content

[0009] In response to the above technical problems, a disposable sampler is provided.

[0010] The technical means adopted by this utility model are as follows:

[0011] A disposable sampler, the sampler is an integrated structure, in the shape of a through groove, and its cross section is arc-shaped, including a thick section, a thin section and a gradient section connecting the thick section and the thin section;

[0012] The groove walls at the ends of the thick section and the thin section extend downwardly in an arc shape in the length direction of the sampler to the groove bottom, so that the orthographic projection of the end of the groove bottom on the horizontal plane is arc-shaped;

[0013] The groove bottoms of the thick section, the thin section and the gradual section are in the same arc surface and at the same height, ensuring that the three sections are in a connected state without blocking each other and the groove inside the sampler is smooth.

[0014] Preferably, the lower edges of the ends of the thick section and the thin section are chamfered, thereby making the ends smooth and not sharp, and gradually thinning the wall thickness to facilitate sampling.

[0015] Preferably, the cross-sections of the thin section and the thick section are semicircular, so that the outer walls thereof can better fit the container bottle or test tube.

[0016] Preferably, the outer diameter of the thin segment is smaller than the inner diameter of the bottle mouth of the 2.5 ml container bottle or test tube, and the length is greater than the height of the 2.5 ml container bottle or test tube.

[0017] Preferably, the outer diameter of the thick section is smaller than the inner diameter of the bottle mouth of the 4 ml container bottle or test tube, and the length is greater than the height of the 4 ml container bottle or test tube.

[0018] Preferably, the length of the sampler is 18 cm, the length of the thick section is 13 cm, the length of the thin section is 4 cm, and the length of the gradient section is 1 cm.

[0019] Preferably, the sampler material is an organic plastic material that is mass-produced by injection molding, and the breathing bag is individually packaged and sterilized by ethylene oxide fumigation.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] 1. The disposable sampler provided by the utility model has a groove design, which can be used to shovel the sample into the groove when the sample is small. At the same time, the arc-shaped groove is designed to facilitate the sampler to scrape the sample attached to the container bottle into the groove in the bottle, so as to achieve the effect of taking out all the samples.

[0022] 2. The disposable sampler provided by the utility model is in the shape of a through groove as a whole. After the sample is taken, the sample can be spread on the bottom of the groove by tilting the sampler, and will not be higher than the groove wall. In the process of transfer, the sample is set in the groove and is not easy to spill.

[0023] 3. The disposable sampler provided by the utility model has a thin section and a thick section, which can be used for 2.5ml and 4ml container bottles or test tubes as well as container bottles or test tubes with larger volumes. Even container bottles with larger volumes can also be sampled using the thick section, which has a wider range of applications.

[0024] 4. The disposable sampling bottle provided by the utility model is a disposable sampler with low manufacturing cost and easy use.

[0025] Based on the above reasons, the utility model can be widely promoted in the fields of sample taking and the like. BRIEF DESCRIPTION OF THE DRAWINGS
