[0002] Sampling swabs are usually dry swabs. After sampling, the sampling swab with the sample is usually placed in a protective agent (or preservative) for preservation. Since the formulas of various protective agents are different and most of them are chemical reagents, which are somewhat corrosive, it is impossible to soak the dry swab directly in the protective agent and then use the wetted swab head for human body sampling.

[0003] For example, the Chinese utility model patent with announcement number: CN218792324U, an ophthalmic swab sampler, which includes: a first tube with an opening at one end and a second tube, the second tube is embedded in the inner cavity of the first tube in a manner that the opening direction is opposite to the opening direction of the first tube, and a first cavity is formed between the second tube and the first tube, wherein one of the first tube and the second tube is used as a sampling tube and the other is used as a swab tube; the swab is arranged in the inner cavity of the swab tube; the first sealing member is used to seal the open end of the sampling tube; the second sealing member is used to seal the open end of the swab tube; the ophthalmic swab sampler of the utility model only needs to open the sealing member of the swab tube when sampling, and the swab can be taken out for sampling, thereby preventing the protective agent from being exposed prematurely, reducing the risk of contamination, and improving the accuracy and efficiency of sampling detection; and, during the process of taking the swab, the protective agent is always in a sealed state, and there is no need to worry about it spilling due to operational errors, which indirectly improves the sampling efficiency.

[0004] The ophthalmic swab sampler mentioned above has the advantages of "reducing contamination risk and improving sampling efficiency".

[0005] However, when the inventors used the device, they found the following problems: when using the device, when using a swab for collection, there is a problem of cumbersome operation, which is very inconvenient to use. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] See also Figure 1-4 The utility model provides a technical solution: an ophthalmic swab sampler, comprising a sampling tube 1, the upper and lower ends of the sampling tube 1 are open ends, a cavity 11 is formed inside the sampling tube 1, a preservative tube body 2 is provided at the lower end of the sampling tube 1, a detachable cover 3 is provided at the upper end of the sampling tube 1, an externally threaded plug 31 is provided at the lower end of the cover 3, a pluggable swab assembly 4 is provided at the lower end of the externally threaded plug 31, and a liquid pushing assembly 5 is provided at the lower end of the preservative tube body 2.

[0027] Specifically, the sampling tube 1 can store the sampling head 43 after sampling and can store the protective agent. The swab component 4 can collect samples from the patient's eyes. The liquid pushing component 5 can push the protective agent into the interior of the sampling tube 1, so that the sample on the sampling head 43 can be fused with the protective agent for subsequent testing.

[0028] like Figure 2 、 Figure 3As shown: the lower end surface of the external threaded plug 31 is provided with an inwardly recessed plug groove 32, and the inner wall of the plug groove 32 is provided with an annular clamping groove 321. This design can be used to plug in the swab assembly 4.

[0029] A leak-proof ring 12 is provided on the upper side of the inner wall of the cavity 11 . This design can prevent the protective agent from splashing when the sampling head 43 is folded.

[0030] An inner thread groove 13 is provided on the inner wall of the cavity 11 . The inner thread groove 13 is designed at the upper end of the leak-proof ring 12 . This design enables the cover 3 to be installed.

[0031] The swab assembly 4 includes a head 41, a rod 42, and a sampling head 43 arranged in sequence from top to bottom, wherein the outer wall of the head 41 extending into the inner part of the plug-in slot 32 is provided with an elastic snap ring 411, and the elastic snap ring 411 can be snapped into the interior of the annular snap groove 321. This design can collect samples from the patient's eyes.

[0032] The upper end surface of the preservative tube 2 is provided with a liquid injection port 21. Inside the liquid injection port 21 is a sealing sheet 22 consisting of six triangular baffles 221. The sealing sheet 22 is tilted upward. This design can separate the preservative tube 2 and the cavity 11, preventing the protective agent from flowing between the preservative tube 2 and the cavity 11.

[0033] The liquid pushing assembly 5 includes a movable rod 51 , and one end of the movable rod 51 extending into the cavity 11 is provided with a pushing piece 52 . This design can apply pressure to the preservative tube 2 , thereby injecting the preservative into the cavity 11 .

[0034] A push head 53 is provided at one end of the movable rod 51 away from the pushing piece 52 . This design can not only push the pushing piece 52 , but also play a supporting role.

[0035] The specific working principle of this embodiment is as follows: when collecting blood from the patient's eyes, first rotate the cover 3 to disengage the external thread plug 31 from the internal thread groove 13, and then take out the swab assembly 4 from the sampling tube 1 for use. When in use, pinch the cover 3 and wipe the patient's eyes with the sampling head 43 to collect the corresponding sample. After collecting, insert the sampling head 43 into the cavity 11. When the sampling head 43 reaches the lower end of the leak-proof ring 12, break the rod 42 so that the sampling head 43 falls into the cavity 11. At this time, pull out the rod 42 and the head 41 from the lower end of the external thread plug 31. After pulling out, cover the upper end of the sampling tube 1 with the cover 3.

[0036] After the lid 3 is closed, the push head 53 is pushed, and synchronously, the movable rod 51 drives the pushing plate 52 to push. As the pushing plate moves, the protective agent in the preservative tube body 2 will be squeezed out from between the multiple baffles 221. At this time, gaps will be generated between the multiple baffles 221 until the protective agent is fully squeezed into the cavity 11 and submerges the sampling head 43. When the protective agent is squeezed out, the multiple baffles 221 will be reset to form a sealing sheet 22 to prevent the liquid in the cavity 11 from flowing back into the protective agent tube body. After a certain period of fusion, the lid 3 can be opened, and the protective agent in the cavity 11 can be taken out and tested to analyze the patient's condition.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
