Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sampling, and in particular relates to an integrated device for holding and breaking a sampling cotton swab. Background Art
[0002] Cotton swab sampling is a commonly used method for collecting biological samples. It is usually used to collect cell or microbial samples from the oral cavity, nasal cavity, skin and other parts. This sampling method involves gently wiping the part to be collected with a cotton swab to allow cells or microorganisms to adhere to the cotton swab, and then placing the cotton swab in an appropriate container for storage or inspection.
[0003] When collecting samples, staff need to quickly break the sampling cotton swab. At present, on the one hand, research has been conducted on setting a breaking notch or breaking hole on the sampling tube. However, this design is of fixed size and has limitations on breaking cotton swabs of different diameters, which can easily limit the use of the sampling tube. On the other hand, setting notches of different sizes on the cotton swab rod can effectively and quickly break the cotton swab. However, this type of cotton swab not only increases the difficulty of production and increases the collection cost, but also greatly reduces the overall bending resistance of the cotton swab. It is difficult to make close contact with the surface in special samples, which reduces the sampling quality. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] This specific embodiment is an integrated device for holding and breaking a sampling cotton swab, and its structural schematic diagram is as follows: Figure 1-Figure 2As shown, it includes a housing, a pry bar 5, a roller 2, a positioning button 3, a support block 10, etc. The pry bar 5 is composed of a short rod and a long rod combined end to end, and the fixed combination is at an obtuse angle. The end of the short rod is equipped with a blade 7, and the middle area of the long rod is hollowed out. The two sides of the combination are hinged to the housing through a short shaft 8. The roller 2 is installed on the longitudinal upper end face of the housing, and its cylindrical surface is higher than the surface of the housing, and the lower end of the cylindrical surface is in contact with the sampling cotton swab 1 rod. The rolling shaft 9 inside the roller 2 is hinged to the housing. The positioning button 3 is also installed on the longitudinal upper end face of the housing, and the contact rod at the bottom of the button passes through the housing and contacts the sampling cotton swab 1 rod. The sampling cotton swab 1 rod is inserted into the device through the circular hole on the transverse end face of the housing, passes through the gap between the roller 2 and the blade 7 and the middle empty area of the pry bar 5, and its tail is in contact with the support block 10.
