Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a rapid sputum sample picking inoculation loop. Background Technique
[0002] In current hospitals, the laboratory department of the hospital receives a large number of sputum specimens every day for inoculation, culture, and identification. However, due to different diseases and different immune systems of patients, the properties of sputum vary greatly. A large part of the sputum is very viscous, and it is difficult to obtain the pathogenic bacteria-bearing part with a standard inoculation loop, and it is even difficult to obtain sputum. Laboratory technicians will perform a large number of repetitive picking operations on sputum, wasting a lot of time. There are also some sputums that cannot be separated from the original specimen due to viscosity problems. Sometimes, relying on the design of the sputum box itself, the upper cover of the sputum box is used to cut it off, but at the same time, it may cause problems of human operation contamination. Therefore, we urgently need a device that can quickly sample sputum through simple operations, quickly disconnect the sample from the specimen in the sputum box, and then perform inoculation. Content of the Utility Model
[0003] The utility model completes the utility model by setting a connecting ring 4 with sawteeth in the inoculation loop to pick up and cut the sputum specimen of the patient, which is convenient for sampling and inoculation.
[0004] The utility model provides a rapid sputum sample picking inoculation loop, which includes two connecting rods 2 and a hand-held part 1 arranged at one end of the connecting rod 2. The other end of one of the connecting rods 2 is provided with an upper inoculation loop 4, and the other end of the other connecting rod 2 is provided with a lower inoculation loop 5; a connecting shaft 3 is arranged at a certain position in the middle of the two connecting rods 2, and the two connecting rods 2 are rotatably connected to the connecting shaft 3 through the connecting shaft 3, so that the two connecting rods 2 are in a scissor shape, which is convenient for quickly picking up sputum samples.
[0005] Further, on the side of the upper inoculation loop 4 facing the lower inoculation loop 5, an upper loop sawtooth 7 is provided. On the side of the lower inoculation loop 5 facing the upper inoculation loop 4, a lower loop sawtooth 6 is provided. The upper loop sawtooth 7 is arranged outside the lower inoculation loop 5 and has a diameter smaller than the inner diameter of the lower inoculation loop 5 so that it can enter the lower inoculation loop 5. The lower loop sawtooth 6 is arranged inside the lower inoculation loop 5, and the shapes of the upper loop sawtooth 7 and the lower loop sawtooth 6 match each other.
[0006] Furthermore, the height of the lower loop sawtooth 6 is 1 / 2 of the lower inoculation loop 5.
[0007] Further, the shape of the hand-held part 1 is semi-circular, which is convenient for medical staff to hold.
[0008] Compared with the prior art, a rapid sputum sample picking inoculation loop provided by the utility model has the following technical advantages:
[0009] For a rapid sputum sample picking inoculation loop provided by the utility model, by arranging a scissors-shaped connecting rod 2, it is more labor-saving and convenient for medical staff to use; by arranging cutting sawteeth on the inoculation loop, it is convenient to cut sputum specimens; by arranging the lower loop sawteeth 6 on the lower loop 5 of the inoculation loop inside the lower loop 5 of the inoculation loop, it can avoid scratching the culture medium when inoculating on the culture medium, thus causing unnecessary trouble.
[0010] Other features and advantages of the utility model will be described in detail in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] To further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manner, structure, features and their effects of the utility model as follows.
[0017] Embodiment A rapid sputum sample picking inoculation loop
[0018] As Figures 1-3 shown
[0019] A rapid sputum sample picking inoculation loop includes two connecting rods 2 and a holding part 1 arranged at one end of the connecting rod 2. The other end of one connecting rod 2 is provided with an upper loop 4 of the inoculation loop, and the other end of the other connecting rod 2 is provided with a lower loop 5 of the inoculation loop; a connecting shaft 3 is arranged at a certain position in the middle of the two connecting rods 2, and the two connecting rods 2 are rotatably connected to the connecting shaft 3 through the connecting shaft 3, so that the two connecting rods 2 are in a scissors shape, facilitating the rapid picking of sputum samples.
[0020] In this embodiment, on one side of the upper ring 4 of the inoculation loop facing the lower ring 5 of the inoculation loop, there is an upper ring serration 7. On one side of the lower ring 5 of the inoculation loop facing the upper ring 4 of the inoculation loop, there is a lower ring serration 6. The upper ring serration 7 is arranged outside the lower ring 5 of the inoculation loop and has a diameter smaller than the inner diameter of the lower ring 5 of the inoculation loop so that it can enter the lower ring 5 of the inoculation loop. The lower ring serration 6 is arranged inside the lower ring 5 of the inoculation loop. The shapes of the upper ring serration 7 and the lower ring serration 6 cooperate with each other to facilitate the cutting of the sputum specimen. The lower ring serration 6 on the lower ring 5 of the inoculation loop is arranged inside the lower ring 5 of the inoculation loop to avoid scratching the culture medium when inoculating on the culture medium, thus causing unnecessary trouble.
[0021] The height of the lower ring serration 6 is 1 / 2 of the lower ring 5 of the inoculation loop.
