Description

Technical Field

[0001] The utility model belongs to the technical field of sampling devices, and particularly relates to a pathological specimen sampling device. Background Art

[0002] In some cases, it is necessary to collect combined samples. The collection of combined samples is to put multiple samples into a sampling tube for collection and transportation. This method can save resources and facilitate comprehensive analysis. First, the sampling personnel should wear protective equipment and prepare a sterile sampling tube with preservation liquid. After using sterile cotton swabs to collect samples from different sampling sites or individuals respectively, the cotton swabs are successively placed into the same sampling tube, ensuring that the head of each cotton swab is completely immersed in the preservation liquid. Squeeze each cotton swab to release the sample into the preservation liquid, and gently shake the test tube to mix the samples. Finally, seal the sampling tube and clearly mark all relevant information, and transport or store the samples as soon as possible according to the requirements of the preservation liquid to ensure the stability of the samples and the accuracy of the analysis results.

[0003] When extracting the preservation liquid for laboratory analysis, it is necessary to squeeze the cotton swab head to release the preservation liquid. Currently, the sampling device is generally a sampling tube made of elastic material. By manually squeezing the tube wall to contact the cotton swab head to squeeze out the preservation liquid, however, in the case of collecting combined samples, it is difficult to operate on multiple cotton swab heads simultaneously, resulting in the preservation liquid squeezed out from one cotton swab head being absorbed by another cotton swab head, and the operation is rather inconvenient. For this reason, we propose a pathological specimen sampling device. Content of the Utility Model

[0004] In order to solve the problem that the current sampling device is generally a sampling tube made of elastic material, and the preservation liquid is squeezed out by manually squeezing the tube wall to contact the cotton swab head, however, in the case of collecting combined samples, it is difficult to operate on multiple cotton swab heads simultaneously, resulting in the preservation liquid squeezed out from one cotton swab head being absorbed by another cotton swab head, and the operation is rather inconvenient, the utility model provides the following technical solution: A pathological specimen sampling device, including a sampling tube, a sealing cap threadedly connected to the top of the sampling tube, and a sampling cotton swab used in cooperation with the sampling tube. A filter disc is arranged in the sampling tube, and the side wall of the filter disc is slidably connected to the inner wall of the sampling tube. A support rod is arranged on the top of the filter disc. Through holes and sliding grooves are formed in the filter disc, and the through holes and the sliding grooves communicate with each other. The diameter of the through hole is larger than the diameter of the head of the sampling cotton swab. The rod part of the sampling cotton swab can slide along the sliding groove, and the sliding groove can prevent the head of the sampling cotton swab from passing through. The bottom of the sampling tube is elastic. A drain pipe is arranged on the top of the sealing cap, and a pipe cap is threadedly connected to the top of the drain pipe.

[0005] Preferably, when the top of the support rod is connected to the lower wall of the sealing cap, the distance between the bottom of the filter disc and the bottom wall of the sampling tube is between 10 - 15 mm.

[0006] Preferably, there are a plurality of the support rods, and the plurality of the support rods are arranged on the top of the filter disc at uniform intervals. Support discs are arranged on the tops of the plurality of the support rods. By arranging the support discs, it is helpful for the support rods to support at the bottom of the sealing cover.

[0007] Preferably, a breaking part is arranged on the sampling cotton swab, and the length from the breaking part to the head of the sampling cotton swab is less than the length of the sampling tube.

[0008] Preferably, the bottom width of the cross-section of the sliding groove is greater than the top width.

[0009] Preferably, the cross-section of the sliding groove is a regular isosceles trapezoid.

[0010] Preferably, the sampling tube is made of polypropylene or polyethylene material.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Firstly, a specimen is sampled by holding the sampling cotton swab by hand. After sampling is completed, the head of the sampling cotton swab is inserted into the sampling tube with the head facing the tube orifice of the sampling tube. After the head of the sampling cotton swab passes through the through hole of the filter disc, the rod part of the sampling cotton swab slides along the sliding groove. Then, the rod part of the sampling cotton swab is broken and discarded through the breaking part. The sampling cotton swabs for multiple samplings are inserted into the sampling tube in the same manner in sequence. Then, the sealing cover is threadedly installed on the sampling tube. The bottom of the sealing cover pushes the filter disc downward through the support rod, so that the filter disc moves all the sampling cotton swabs towards the bottom of the sampling tube, enabling the heads of the sampling cotton swabs to be completely immersed in the preservation liquid at the bottom of the sampling tube, so that the sample can dissolve in the preservation liquid. When it is necessary to pour out the preservation liquid, the tube cap is disassembled by threading, the sampling tube is inverted, and a finger presses downward on the bottom of the sampling tube, causing the bottom of the sampling tube to be indented inward and contact the head of the sampling cotton swab, so that the head of the sampling cotton swab can be simultaneously squeezed between the bottom of the sampling tube and the filter disc, so that the preservation liquid absorbed by the head of the sampling cotton swab can be released, flow down through the through hole and the sliding groove on the filter disc, and flow downward through the drain pipe, so that more preservation liquid containing the sample can be obtained.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0019] It is composed of Figures 1-3 As shown, the present utility model includes a sampling tube 1, a sealing cap 2 threadedly connected to the top of the sampling tube 1, a sampling cotton swab 7 used in cooperation with the sampling tube 1, a filter disc 3 arranged inside the sampling tube 1, the side wall of the filter disc 3 is slidably connected to the inner wall of the sampling tube 1, a support rod 4 is arranged on the top of the filter disc 3, through holes 5 and slide grooves 6 are formed on the filter disc 3, the through holes 5 and the slide grooves 6 are communicated with each other, the diameter of the through holes 5 is larger than the diameter of the head of the sampling cotton swab 7, the rod part of the sampling cotton swab 7 can slide along the slide groove 6, and the slide groove 6 can prevent the head of the sampling cotton swab 7 from passing through. The bottom of the sampling tube 1 is elastic, a drain pipe 10 is arranged on the top of the sealing cap 2, and a tube cap 11 is threadedly connected to the top of the drain pipe 10.

[0020] When the top of the support rod 4 is connected to the lower wall of the sealing cap 2, the distance between the bottom of the filter disc 3 and the bottom wall of the sampling tube 1 is between 10 - 15 mm.

[0021] There are multiple support rods 4, and the multiple support rods 4 are arranged on the top of the filter disc 3 at equal intervals. Support discs 9 are arranged on the tops of the multiple support rods 4. By setting the support discs 9, it helps the support rods 4 to support on the bottom of the sealing cap 2.

[0022] A breaking part 8 is arranged on the sampling cotton swab 7, and the length from the breaking part 8 to the head of the sampling cotton swab 7 is less than the length of the sampling tube 1.

[0023] The bottom width of the cross-section of the slide groove 6 is larger than the top width.

[0024] The cross-section of the slide groove 6 is a regular isosceles trapezoid.

[0025] The sampling tube 1 is made of polypropylene or polyethylene material.

[0026] Working principle: During operation, first, a specimen is sampled using a handheld sampling swab 7. After sampling, the head of the sampling swab 7 is inserted into the sampling tube 1 with the head facing the orifice of the sampling tube 1. After the head of the sampling swab 7 passes through the through-hole 5 of the filter disc 3, the rod of the sampling swab 7 slides along the chute 6. Then, the rod of the sampling swab 7 is broken off and discarded through the breaking part 8. The above operations are repeated to insert multiple sampled sampling swabs 7 into the sampling tube 1 in sequence. Then, the sealing cap 2 is threadedly installed on the sampling tube 1. The bottom of the sealing cap 2 pushes the filter disc 3 downward through the support rod 4, causing the filter disc 3 to move all the sampling swabs 7 towards the bottom of the sampling tube 1, so that the heads of the sampling swabs 7 can be completely immersed in the preservation liquid at the bottom of the sampling tube 1, enabling the sample to dissolve in the preservation liquid. When it is necessary to pour out the preservation liquid, the tube cap 11 is removed by threading, the sampling tube 1 is inverted, and a finger presses downward on the bottom of the sampling tube 1, causing the bottom of the sampling tube 1 to be indented inward and contact the head of the sampling swab 7, so that the head of the sampling swab 7 can be squeezed simultaneously between the bottom of the sampling tube 1 and the filter disc 3. As a result, the preservation liquid absorbed by the head of the sampling swab 7 can be released, flowing down through the through-hole 5 and the chute 6 on the filter disc 3 and out through the drain pipe 10, thereby enabling more preservation liquid containing the sample to be obtained.
