Description

Technical Field

[0001] The utility model relates to a sampling device, in particular to a sampling device for viruses and bacteria, belonging to the technical field of sampling. Background Art

[0002] At present, the new coronavirus detection mostly uses cotton swabs to smear the sampling area. The cotton swabs are disposable and are placed in a packaging bag. Therefore, the staff needs to tear open the packaging bag, take out the cotton swab and take a sample, then open the test tube bottle that stores the cotton swab, put the cotton swab into the test tube bottle and seal the test tube bottle. During the above operation, there is also the possibility that the cotton swab is too long and the staff needs to break it and put the broken cotton swab head into the test tube bottle. This makes the entire sampling process complicated and troublesome. If the staff completes it independently, they will be in a hurry and it is easy to make operational errors that affect the sampling progress and sampling results. Utility Model Content

[0026] The embodiment of the utility model provides a sampling device for viruses and bacteria.

[0027] See also Figures 1 to 5 , comprising a tube body 1, a placement groove 11 is provided on the upper part of the tube body 1, a cotton swab rod 10 is placed in the placement groove 11, a tube cover 4 is threadedly sleeved on the top of the tube body 1, the tube cover 4 is adapted to the notch of the placement groove 11, a through hole is provided on the upper part of the tube cover 4 to be slidably connected to the cotton swab rod 10, and a leather cover 6 is fixedly connected to the notch of the through hole of the tube cover 4, and the leather cover 6 is located on the upper part of the tube cover 4;

[0028] The staff opens the tube cover 4 and pinches the leather case 6, and clamps the top end of the cotton swab rod 10 in the leather case 6, and then uses the cotton swab rod 10 to take samples. After the sampling is completed, the sampling end of the cotton swab rod 10 is placed in the placement groove 11, and the tube cover 4 is used to cover or seal the notch of the placement groove 11, so that the entire sampling work is completed;

[0029] The leather cover 6 is a plastic belt, and the leather cover 6 is relatively thin, mainly to facilitate the staff to pinch the cotton swab rod 10, and can also seal the through hole, so that after the tube cover 4 covers the tube body 1, the cavity of the placement groove 11 is always in a sealed state.

[0030] See also Figure 2 and Figure 3 The bottom wall of the placement groove 11 is formed with a liquid medicine groove 8, and a piston plate 9 is slidably connected in the placement groove 11;

[0031] The medicine tank 8 is used to store medicine liquid that can preserve viruses and bacteria for a long time. The piston plate 9 is used to separate the medicine tank 8 and the placement tank 11, so as to prevent the medicine liquid in the medicine tank 8 from leaking out of the tube body 1. In this way, when the tube cover 4 is opened, the medicine liquid in the tube body 1 can also be kept intact and stable, and there is no need to worry about the problem of the tube body 1 tipping over and causing the medicine liquid to leak out.

[0032] After the sampling is completed, when the tube cover 4 seals the notch of the placement groove 11, the cotton swab rod 10 is pushed at the same time, and the piston plate 9 is slightly squeezed by the cotton swab rod 10, so that the piston plate 9 slides from the placement groove 11 into the medicine liquid groove 8. The inner diameter of the medicine liquid groove 8 is larger than the outer diameter of the piston plate 9, so that the sealing state of the medicine liquid groove 8 can be opened, and the cotton ball 15 at the head of the cotton swab rod 10 can be immersed in the medicine liquid.

[0033] See also Figure 2 and Figure 3 The diameter of the notch of the horizontal cross section of the liquid medicine tank 8 is larger than the diameter of the notch of the horizontal cross section of the placement tank 11.

[0034] See also Figure 5 The piston plate 9 is made of rubber, and a through-type pinhole 14 is provided on the upper portion of the piston plate 9. A connecting block 13 is fixedly connected to the upper portion of the piston plate 9, and a first thread groove is provided on the upper portion of the connecting block 13;

[0035] When installing the piston plate 9, it is necessary to use the long rod 7 to push the piston plate 9 to move in the placement groove 11 until the piston plate 9 moves to the notch of the placement groove 11 close to the medicine liquid groove 8. At this time, the excess air in the medicine liquid groove 8 will be discharged from the pinhole 14 due to the pushing pressure;

[0036] Since the pinhole 14 has a small diameter and the piston plate 9 is mostly in a slimming and compressed state, the pinhole 14 is generally in a compressed and sealed state, which can basically avoid the problem of liquid medicine leaking from the hole; the piston plate 9 is made of a material such as rubber or silicone that does not react chemically and the placement groove 11.

[0037] See also Figure 5 The upper part of the tube body 1 is provided with a mounting groove 16, in which a long rod 7 is slidably connected, and an external thread connected to the first thread groove is provided at the end of the long rod 7, and a second thread groove is formed on the bottom wall of the mounting groove 16, and the second thread groove is threadedly connected to the external thread provided at the end of the long rod 7;

[0038] The external thread at the end of the long rod 7 is threadedly connected to the first thread groove, so that the long rod 7 and the piston plate 9 can be fixed to each other, so that the piston plate 9 located in the liquid medicine tank 8 can be taken out by using the long rod 7, so that the tube body 1 can be reused for the second time;

[0039] The mounting groove 16 is used to store the long rod 7. When the long rod 7 is not needed, the long rod 7 is inserted into the mounting groove 16 and the long rod 7 is rotated so that the external thread at the end of the long rod 7 is threadedly connected with the second thread groove, so that the long rod 7 can be fixed in the cavity of the mounting groove 16.

[0040] See also Figures 1 to 3 , a groove 5 is formed on the upper part of the tube cover 4, and a through hole is formed on the inner wall of the groove 5;

[0041] After the cotton swab rod 10 is completely inserted into the test tube, the leather case 6 can be squeezed and inserted into the groove 5, so that the leather case 6 is easy to store.

[0042] See also Figure 1 to Figure 2 A transparent plate 2 is fixedly connected to one side of the tube body 1, and a paper slot 3 is opened on the upper part of the transparent plate 2;

[0043] The sequence or related content of the test tube can be written on the label, and then the label can be inserted into the paper slot 3 to complete the installation of the label. The transparent plate 2 can facilitate the disassembly and installation of the label, as well as viewing the content on the label.

[0044] See also Figure 1 and Figure 2 , a cotton ball 15 is arranged at the bottom end of the cotton swab rod 10, and a rubber plug 12 is installed at the top end of the cotton swab rod 10;

[0045] The cotton ball 15 is used to contact the sampling site so that the sample can stick to the cotton ball 15, and the rubber plug 12 is used to plug the through hole on the tube cover 4, so as to improve the stability of the inside of the tube body 1 to prevent the drug solution from flowing into the leather case 6 along the through hole.
