[0021] As shown by Figures 1 to 5 , the present utility model includes a box body 1 and at least one placement unit arranged inside the box body 1. Each said placement unit includes a placement hole 10 arranged inside the box body 1, a placement cup 102 which is placed in the placement hole 10 in a limited way and contains an ice pack, a limiting ring 101 fixed on the hole wall of the placement hole 10, a bottom plate 11 screwed in the placement hole 10 and abutted against the upper end surface of the limiting ring 101, and at least one sampling cotton swab 2 passing through the bottom plate 11 and connected with the bottom plate 11 in a clamping manner; a rubber stopper 3 sleeved outside the sampling cotton swab 2 is arranged at the position corresponding to the passing position of the sampling cotton swab 2 on the bottom plate 11.
[0022] Specifically, a notch is arranged at the lower end position corresponding to the placement hole 10 on the box body 1, and a sealing door 13 is hinged at this notch position; a horizontally extending limiting rod 111 is arranged on one side of the placement cup 102. When placing, open the sealing door 13, put the placement cup 102 into the placement hole 10, and make the placing end of the placement cup 102 abut against the hole wall of the placement hole 10. The cup mouth end surface of the placement cup 102 fits with the lower end surface of the limiting ring 101, then close the sealing door 13, and make the end surface of the extending end of the limiting rod 111 abut against the inner side wall of the sealing door 13, so as to limit and fix the placement cup 102.
[0023] Two bosses 21 are symmetrically provided at the rod position of the sampling cotton swab 2, and limiting grooves 16 are provided at the positions corresponding to the bosses 21 on the upper end surface of the base plate 11, and the bosses 21 at the corresponding ends are inserted into the limiting grooves 16; a clearance hole 17 for the cotton ball part of the sampling cotton swab 2 to pass through is connected at the position between the two limiting grooves 16 on the base plate 11.
[0024] The groove shape of the limiting groove 16 matches the outer shape of the boss 21 , and the outer wall size of the boss 21 matches the inner wall size of the limiting groove 16 , so that the boss 21 forms a snap-fitting and positioning state when inserted into the limiting groove 16 .
[0025] In addition, a gap is provided between the outer side wall of the rod of the sampling cotton swab 2 and the hole wall of the give way hole 17, an annular boss 31 is provided at a position corresponding to the gap on the rubber plug 3, a guide groove 33 is provided on the annular boss 31 at a position corresponding to the boss 21, and a through hole 32 is provided in the middle of the rubber plug 3; when in use, the rod of the sampling cotton swab 2 is passed through the through hole 32, and the annular boss 31 is extended into the gap, the guide groove 33 is sleeved on the outer side wall of the boss 21, and the lower end surface of the rubber plug 3 abuts against the upper end surface of the bottom plate 11.
[0026] A handle 112 protruding from the placement hole 10 is provided on the bottom plate 11 .
[0027] The operating principle of the utility model is as follows:
[0028] like Figures 1 to 5 As shown, before use, the handle 112 is driven to screw the bottom plate 11 into the placement hole 10, and the upper end surface of the limiting ring 101 is abutted against the corresponding position of the lower end surface of the bottom plate 11 to achieve the closure of the lower end portion of the placement hole 10. Then, an ice bag ( Figure 1 As for the placement cup 102 at the position shown in the dotted line box, since a horizontally extending limiting rod 111 is provided on one side of the placement cup 102, when placing, the sealing door 13 is opened, the placement cup 102 is placed in the placement hole 10, and the placement end of the placement cup 102 is abutted against the hole wall of the placement hole 10, and the cup mouth end face of the placement cup 102 is fitted with the lower end face of the limiting ring 101, and then the sealing door 13 is closed, and the end face of the extended end of the limiting rod 111 is abutted against the inner side wall of the sealing door 13, so that the placement cup 102 is limited and fixed so as not to move, that is, the position of the cooling source is stabilized, and the cooling efficiency of the air in the placement hole 10 is guaranteed.
[0029] Subsequently, insert the sampling cotton swab 2 at the position of the relief hole 17 on the bottom plate 11, and insert the boss 21 into the limiting groove 16. Since the groove shape of the limiting groove 16 matches the outer shape of the boss 21, and the size of the outer side wall of the boss 21 is adapted to the size of the inner side wall of the limiting groove 16, when the boss 21 is inserted into the limiting groove 16, a clamped and positioned state is formed, that is, the sampling cotton swab 2 is not easily loosened and fallen out, which is convenient for the box body 1 to be moved and transferred.
[0030] Finally, the rod part of the sampling cotton swab 2 passes through the through hole 32, and the annular boss 31 is pushed into the gap between the outer side wall of the rod part of the sampling cotton swab 2 and the hole wall of the relief hole 17. The guiding groove 33 is sleeved on the outer side wall of the boss 21, and the lower end surface of the rubber plug 3 abuts against the upper end surface of the bottom plate 11, so as to seal the position of the relief hole 17, prevent cold air from leaking out, and at the same time limit the boss 21, further preventing the sampling cotton swab 2 from falling out.
[0031] After the pre-cooling time in the placement hole 10 is up, remove the rubber plug 3 and pull out the sampling cotton swab 2. After sampling, insert the sampling cotton swab 2 through the bottom plate 11 again, and make the cotton ball position extend into the placement hole 10, and continue to keep the cold air around the ice pack cooling the sample. Then put on the rubber plug 3 at the position of the relief hole 17. At this time, it not only prevents cold air from leaking out, but also cuts off the outside air from entering the placement hole and reacting with the saliva sample, improving the storage efficiency of the saliva sample.
[0032] Among them, since the bottom plate 11 is screwed in the placement hole 10, the insertion position of the sampling cotton swab 2 is stable and will not cause the cotton ball position to be touched, so as to avoid the lack of sample collection volume.
[0033] It should be noted that in order to better maintain the service life of the ice pack, a sealing ring (not marked) is wound around the outer side wall of the sealing door 13. When closed, the outer side wall of the sealing ring abuts against the outer side wall of the notch position to achieve the purpose of sealing the placement hole 10; at the same time, this embodiment is used under the condition of no sample preservation solution. When sampling for ordinary detection, the cooling of the air in the placement hole 10 by the ice pack can reach about 0°C after pre-cooling, and the melting period of the ice pack in the closed space is 6-20 hours. Under the premise of pre-cooling, it meets the requirements of short-term low-temperature preservation of saliva.
[0034] The refrigerated saliva samples are taken out one by one before testing and separately placed into the corresponding preservation solutions for testing. When DNA testing of the saliva samples is required, the samples refrigerated in the placement holes 10 need to be sent into a refrigeration device at -20°C within one hour to prevent the decomposition of DNA components from affecting the accuracy of the testing. It should be noted that in this embodiment, there are four placement holes 10 on the box body 1, and four relief holes 17 are provided on the bottom plate 11 at each placement hole 10 for inserting the sampling swabs 2. That is, each box body can place sixteen samples at one time, increasing the number of samples sent per unit time, shortening the sample delivery cycle, improving the sample submission efficiency within the effective preservation period, and ensuring the accuracy of sample testing.
