As shown in fig. 1-4, a non-exposure and non-infection sampling device comprises a test tube 1, a first screw cap 2, a second screw cap 3 and a cotton swab 4; the test tube 1 is a hollow structure with two through ends, the two ends of the test tube 1 are respectively provided with an inner port 11 and an outer port 12, the inner port 11 is an end far away from an operator, and the outer port 12 is an end close to the operator; the first screw cap 2 and the inner port 11 are provided with matched threads 6, the first screw cap 2 is screwed down, and the inner port 11 is closed; the second screw cap 3 and the outer port 12 are provided with matched threads 6, the second screw cap 3 is screwed down, and the outer port 12 is closed; the cotton swab 4 is movably sleeved on the test tube, and the length of the cotton swab 4 is greater than that of the test tube 1; a plurality of cutting parts 14 are uniformly distributed on the inner wall of the outer port 12 along the circumferential direction, and the cutting parts 14 are used for cutting off the rod part 42 of the cotton swab 4.
The non-exposure and non-infection sampling device is used for sampling secretion of a patient, such as saliva, nasal liquid, vaginal or anal secretion and the like, can prevent an operator from contacting the secretion of the patient, prevents the sampled secretion from being exposed, protects the operator and prevents the operator from being infected in the sampling process.
After sampling, the cotton swab head 41 of the cotton swab 4 is retracted into the test tube 1, the inner port 11 is sealed by the first spiral cover 2, and the cotton swab head 41 of the cotton swab 4 stays in the test tube 1; utilize cutting part 14 to cut off the pole part 42 of cotton swab 4 makes the cotton swab head 41 and a part pole part 42 of cotton swab 4 who is cut off stay completely in test tube 1, utilizes at last second spiral cover 3 will outer port 12 seals, and the cotton swab 4 who is cut off just stays in sealed test tube, makes whole sampling process shield the influence of external factor. Since the cotton swab 4 dipped with the sample is sealed and isolated immediately after leaving the site to be measured, the medical staff can be prevented from being infected by the sample on the cotton swab 4. In addition, because cutting portion 14 is sharp, the department of rod portion 42 disconnection is level and smooth, can not fish tail medical personnel, and cutting portion 14 is located the inner wall of test tube 1 and cutting opening towards the axis of test tube 1, consequently also can not fish tail medical personnel.
As shown in fig. 2, the sampling device further comprises a protective shutter 5, said protective shutter 5 being provided with an opening 51, the diameter of said opening 51 being the same as the outer diameter of said test tube 1.
When the sampling device is used, the part to be measured is shielded by the protective shield 5, and the test tube 1 is inserted through the opening 51 to sample. The protective shielding piece 5 can prevent secretion, sneeze and the like of a person to be sampled from spraying to medical care personnel, and prevent the medical care personnel from being infected due to sampling.
Preferably, the protective shielding piece 5 is a protective mask or a shielding non-woven fabric. The protective mask or the shielding nonwoven fabric has good secretion or sneeze isolating effect.
Preferably, the rod portion 42 of the cotton swab 4 is provided with a scale. The oral cavity depth which can accurately correspond to the suitable age bracket of the sampled person when the oral cavity is measured; the nasal cavity depth of a person to be sampled in a suitable age period can be accurately corresponded when the nasal cavity is measured; when measuring the vagina, different sampling positions of the vagina can be accurately measured.
As shown in fig. 3, the cutting portion 14 is an arc-shaped blade, which more easily cuts the shaft portion 42 of the swab 4.
As shown in fig. 4, the cutting portion 14 is provided with serrations to cut off the shaft portion 42 of the swab 4 more easily.
A sampling method using the sampling device comprises the following steps: the inner port 11 of the test tube 1 is aligned to the part to be tested, and the cotton swab head 41 of the cotton swab 4 passes through the test tube 1 and then contacts with the part to be tested, so that sampling is completed; after sampling, the test tube 1 and the cotton swab 4 leave the part to be tested, the cotton swab head 41 of the cotton swab 4 is retracted into the test tube 1, and the first spiral cover 2 is screwed down to seal the inner port 11 of the test tube 1; the cutting part 14 of the test tube 1 cuts off the rod part 42 at the tail end of the cotton swab 4, the second screw cap 3 is screwed, and the outer port 12 is closed.
When the sampling device is used, the inner port 11 is aligned with a nasal cavity, an oral cavity, a vaginal opening or an anus, and the diameter of the inner port 11 is basically consistent with that of a part to be detected. The cotton swab 4 passes through the test tube 1 to contact with a part to be tested, and the rod part 42 is rotated to drive the cotton swab head 41 to rotate so as to perform sampling.
After the sampling device finishes sampling and leaves a tested part, the cotton swab head 41 is retracted into the test tube 1, then the first spiral cover 2 is screwed down, the inner port 11 is closed, and the cotton swab head 41 stays in the test tube 1. The cutting portion 14 cuts off the stem portion 42 and finally the second screw cap 3 is applied. After the second spiral cover 3 is screwed down, the outer port 12 is closed, and the cut-off cotton swab 4 stays in the sealed test tube, so that the whole sampling process is shielded from the influence of external factors. Since the cotton swab 4 dipped with the sample is sealed and isolated immediately after leaving the site to be measured, the medical staff can be prevented from being infected by the sample on the cotton swab 4.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention.
