Embodiment 1

[0047] See figure 1 , the umbrella rib type environmental surface sampling stick disclosed in this embodiment includes a protective cap 1, a sleeve handle 2, an umbrella rib type cotton swab 4, a tube body 3 and reagents; the lower end of the tube body 3 seals the upper end opening, and the tube The upper end of the body 3 is nested with a casing handle 2; see figure 2 , the sleeve handle 2 includes a reagent storage bin 21 and a sleeve 22 that runs through the inside of the reagent storage bin 21 and extends out of its bottom. The bottom of the reagent storage bin 21 is provided with a valve that communicates with the inside of the tube body 3; The reagent storage bin 21 is fixedly connected to the inner wall of the top of the reagent storage bin 21. The bottom of the casing 22 is provided with an upper umbrella hub ring 23. The upper umbrella hub ring 23 is fixedly nested on the lowermost outer edge of the sleeve tube 22. Rotate and connect some umbrella rib struts 24; See...

Embodiment 2

[0049] See Figure 5-Figure 7 , the technical solution disclosed in this embodiment is roughly consistent with the technical solution in Example 1, the only difference is that in this embodiment, the valve is composed of a reagent storage compartment bottom plate and a valve ring, and the reagent storage compartment bottom plate and The valve ring is arranged concentrically, the middle part of the bottom plate of the reagent storage chamber is provided with a through hole 26 with a diameter of 0.4 cm for the casing 22 to pass through, and a gap 25 is provided on the edge of the bottom plate of the reagent storage chamber; the valve ring is a 1.8 cm diameter and 0.2 cm thick Disc, the central position of the disc also has a through hole 26 with a diameter of 0.4cm for the casing 22 to pass through, and at the same time, the edge of the valve ring is also provided with a groove 27, see Figure 4 , Figure 10 The inner wall of the tube body mouth is provided with a convex groove...

Embodiment 3

[0054] See Figure 11-Figure 13 , the technical solution disclosed in this embodiment is roughly consistent with the technical solution in embodiment 1, the only difference is that in this embodiment, the upper and lower umbrella hub rings 23 and 44 are evenly spaced on the bottom edge of the outer edge. There are 8 notches, and the rib system is formed by 8 rib bodies 43 and 8 rib struts 24. The 8 rib bodies 43 respectively include 4 long rib bodies and 4 short rib bodies. When the bones are fully extended, the cotton of the canopy takes on a square shape. Specifically, the length of the long rib body is 3.54 cm, and the length of the short rib body is 2.5 cm. When the ribs are fully unfolded, the cotton on the umbrella surface is in a square shape of 5 cm*5 cm. The periphery of the umbrella ribs is wrapped by cotton, and the adjacent umbrella ribs are also connected by cotton.

[0055] Although it is disclosed in this embodiment that when the ribs are fully expanded, the u...

Abstract

The invention discloses an umbrella rib type environmental object surface sampling rod which comprises a protective cap, a sleeve handle, an umbrella rib type cotton swab, a tube body and reagents, wherein the sleeve handle is nested to the upper end of the tube body; the sleeve handle comprises a reagent storage bin and a sleeve; a valve communicated with the interior of the tube body is arrangedat the bottom of the reagent storage bin; the tube body penetrates through the reagent storage bin and is fixedly connected with the inner wall at the top of the reagent storage bin; an upper umbrella hub ring is arranged at the bottom of the sleeve; a plurality of umbrella rib supporting rods are rotationally connected onto the upper umbrella hub ring; the umbrella rib type cotton swab is arranged in the sleeve in a sliding manner; the top of a main rod of the umbrella rib type cotton swab is connected with a spring; a lower upper umbrella hub ring is arranged at the bottom of the umbrella rib type cotton swab and rotationally connected with an umbrella rib body; the middle of the umbrella rib body is rotationally connected with the umbrella rib supporting rods; the umbrella rib body iscoated with sampling cotton; the reagents are stored in the reagent storage bin; the protective cap is arranged above the sleeve handle. According to the umbrella rib type environmental object surfacesampling rod disclosed by the invention, the sampling operation links can be effectively simplified, pollution factors are reduced, and the sampling rod is convenient to carry and preserve.

Description

technical field [0001] The invention relates to a tool for sampling microorganisms on the surface of environmental objects, in particular to an umbrella-shaped environmental object surface sampling stick with a cotton swab head that can be freely retracted. Background technique [0002] Due to various diseases and the flow of people, the hospital environment is in a state of a large number of bacterial pollution every day, especially the pollution of various pathogenic bacteria. It not only pollutes the air but also pollutes the surface of the entire hospital, such as bed units, curtains, treatment carts, door handles, remote controls, office desks and chairs, case clips, stethoscopes, and other medical equipment in the ward. [0003] In accordance with the relevant national requirements for hospital infection management, hospital environmental surfaces need to be cleaned and disinfected regularly, and the cleaning and disinfection effects should be tested regularly. Microb...
