With the movement tendency far from limited block 3, one end of trough floor of the locating rod 10 far from main accommodating groove 9 is connected with position-arresting disk 14,
By the matching between position-arresting disk 14 and locating slot 13, facilitate installation sampling cotton swab pedestal 4, digging on limited block 3 has and push plate
The 12 secondary accommodating grooves to match, and secondary accommodating groove is located at the nozzle of main accommodating groove 9, secondary accommodating groove takes for storing push plate 12
Sampling cotton swab pedestal 4 is connected at the nozzle of sample pipe 1, sampling cotton swab pedestal 4 is sampled for installing plastic bar 5 and Medical cotton 6
A pair of of buckle 7 is connected between pipe 1 and sampling cotton swab pedestal 4, buckle 7 takes for fixing probe tube 1 and sampling cotton swab pedestal 4
The upper and lower ends of sample cotton swab pedestal 4, which are dug, the locating slot 13 to match with position-arresting disk 14, and one end of sampling cotton swab pedestal 4 connects
It is connected to plastic bar 5, Medical cotton 6, plastic bar 5 and Medical cotton 6 are connected on plastic bar 5 for sampling.
Seal rubber washer 15, and seal rubber are connected between probe tube 1 and sampling cotton swab pedestal 4 referring to FIG. 1-2,
Washer 15 is fixedly connected with sampling cotton swab pedestal 4, is interference fit, seal rubber between seal rubber washer 15 and probe tube 1
Washer 15 can increase probe tube 1 and sample the air-tightness between cotton swab pedestal 4, be not easy extraneous pollutant from probe tube 1
Gap between sampling cotton swab pedestal 4 enters in probe tube 1 sample polluted in Medical cotton 6, and seal rubber washer 15 leans on
Nearly probe tube 1 is carved with anti-skid chequer on one side, is equipped with frosted layer at 1 inner wall nozzle of probe tube, anti-skid chequer and frosted layer can increase
Frictional force between probe tube 1 and seal rubber washer 15, after the release of buckle 7, sampling cotton swab pedestal 4 is not easy to be in compression
The compressed spring 11 of state directly bounces, but slowly pops up out of probe tube 1, and sampling personnel is facilitated to take out 5 He of plastic bar
Medical cotton 6, digging in seal rubber washer 15 has cavity, is filled with multiple balls in cavity, and cavity and ball can be with
The elasticity for increasing seal rubber washer 15, facilitates the installation of sampling cotton swab pedestal 4, and ball need to select elastic preferable material system
At, and the size of multiple balls is different, can be not easy while maximizing the elasticity for increasing seal rubber washer 15
Influence the leakproofness of seal rubber washer 15.
Referring to Fig. 1, digging on the side wall of probe tube 1 has a pair of finger slot, it is equipped with silicagel pad in finger groove, conveniently takes
Sample personnel hold probe tube 1, while probe tube 1 being made to be not easy in sampling process to slide from sampling personnel's hand, and instruction film 8 can
Elasticity and the preferable silica gel of toughness is selected to be made, the chemical property of silica gel is relatively stable, the sample in Medical cotton 6 not easy to pollute
Product, and select elasticity and the preferable silica gel of toughness is then while to be not susceptible to indicate thin to make to indicate that 8 sensitivity of film increases
The phenomenon that 8 gas leakage of film.
In plastic bar 5 and Medical cotton 6 before use, plastic bar 5 and Medical cotton 6 are located at sampling at this time referring to FIG. 1-2,
In pipe 1 and transparent rubber set 2, in more closed environment, it is not easy to be polluted by environmental contaminants, when needing to be sampled,
A pair of of buckle 7 is unclamped, under the action of being in compressed spring 11 of compressive state, push plate 12 and sampling cotton swab pedestal 4 are by remote
Rectangular top from limited block 3 is gone, since there are biggish frictional force between seal rubber washer 15 and the inner wall of probe tube 1, therefore
It is slower to sample the speed that cotton swab pedestal 4 pops up, will not directly be popped up out of probe tube 1, it is almost static in sampling cotton swab pedestal 4
Afterwards, sampling cotton swab pedestal 4 is removed out of probe tube 1, and sampling cotton swab pedestal 4 is inverted, and is turned back in probe tube 1, locking is a pair of
Buckle 7 after sampling, unclamps buckle 7, weight at this time referring to Fig. 3, sampling personnel can hold probe tube 1 and be sampled
Multiple aforesaid operations remove sampling cotton swab pedestal 4 out of probe tube 1, turn back to probe tube after sampling cotton swab pedestal 4 is inverted again
In 1, a pair of of buckle 7 is locked, at this time referring to Fig. 1, sampling work is completed, it is reasonable to carry out to probe tube 1 and transparent rubber set 2
Storage, before being detected to sample, need to probe tube 1 and transparent rubber set 2 carry out air-leakage tests, prevent Medical cotton
Sample is polluted by environmental contaminants on 6, only needs that transparent rubber is gently pressed to cover 2 at this time, makes to indicate that film 8 is heaved, in instruction 8 energy of film
Enough when the long period keeping heaving state, illustrate that the air-tightness of probe tube 1 and transparent rubber set 2 is preferable, in the instruction drum of film 8
When quickly shrivelled after rising, illustrate that the air-tightness of probe tube 1 and transparent rubber set 2 is poor, the sample in Medical cotton 6 may be dirty
Dye, should pass into disuse, and the utility model operation is more convenient, and air-tightness is good, is not easy gas leakage, makes the sample on cotton stick swab
Product are not easy to be contaminated, and are not easy to impact the accuracy of sampling work.
Since the utility model is medical field, therefore structure is disposable product in above scheme, is such as imitated for economy
Benefit considers, probe tube 1, transparent rubber set 2 and instruction film 8 also only can be recycled and recycled, and in probe tube 1, transparent rubber
Gum cover 2 and instruction film 8 need to carry out the disinfection and sterilization processing of thoroughly medical level before carrying out secondary use.
The preferable specific embodiment of the above, only the utility model；But the protection scope of the utility model is not
It is confined to this.Anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its improvement design is subject to equivalent substitution or change, should all cover in the protection scope of the utility model
It is interior.
