Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular, to a sampling tube. Background Art

[0002] The currently used disposable virus sampler includes a sampling swab and a sampling tube, and the sampling tube is filled with a preservation solution. Medical staff use the sampling swab to collect samples, so that the sampling head of the sampling swab has a sample, and then the end of the sampling swab with the sampling head is inserted into the sampling tube, and the sampling swab is broken at the breaking point, and the part of the sampling swab with the sampling head falls freely into the preservation solution. The sampling swab is placed irregularly tilted in the sampling tube, and then the tube cap of the sampling tube is tightened and sealed for preservation, so that the sample on the sampling head is fully dissolved in the preservation solution, and finally transported to the laboratory for testing.

[0003] In order to improve the detection process, the existing laboratory detection process mostly uses automatic extractors and automatic samplers for extraction and sampling. Both automatic extractors and automatic samplers are high-precision and high-sensitivity instruments, and the sampling swabs are irregularly tilted in the sampling tube. There is no operating space reserved in the sampling tube for the subsequent automatic extractor or automatic sampler to extend the extraction head or sampler head into the sampling tube for extraction or sampler. If the sampling tube equipped with the sampling swab is directly used for subsequent automatic extraction or automatic sampler operation, the extraction head or sampler head of the automatic extractor and automatic sampler will often automatically alarm and stop when it touches the sampling rod or cotton head, affecting the efficiency. Therefore, in order to automate the extraction or sampler, the front process needs to increase manpower, manually remove the sampling swab from the sampling tube to leave operating space in the sampling tube, and then use the sampling tube without the sampling swab to automatically extract or sample. However, in the entire process of virus detection (such as the new crown pneumonia nucleic acid test), the manual handling of the sampling cotton head increases the risk of infection, and also increases the labor cost and the cost of protective equipment. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a sampling tube that can effectively reduce the risk of infection, simplify the detection process, improve the detection efficiency, and reduce labor costs and protective equipment costs.

[0005] The present application provides a sampling tube, which includes a tube body and a fixing member. The fixing member is arranged in the tube body and is used to fix a sampling swab at a predetermined position in the tube body, so that an operation space is reserved in the tube body.

[0006] In the above implementation process, the medical inspector uses the sampling swab to collect samples, so that the sampling head of the sampling swab is equipped with a sample, and then extends the end of the sampling swab with the sampling head into the sampling tube, and fixes the sampling swab with the fixing part in the sampling tube, and then breaks the sampling swab according to the breaking point, so that the sampling swab remaining in the sampling tube can be fixed in a predetermined position, and the sampling swab at the predetermined position is placed in the sampling tube according to the preset placement method, so as to reserve operating space for subsequent automatic extraction or automatic sampling. After that, when entering the laboratory testing process, there is no need to manually remove the sampling swab from the sampling tube. The sampling tube with the sampling swab can be directly put on the machine for automatic extraction and sampling, which omits the operation steps of manually handling the sampling swab and reduces the high-risk infection links, thereby effectively reducing the risk of infection, simplifying the testing process, improving the automation rate, improving the testing efficiency, and reducing the labor cost and the cost of protective equipment.

[0007] In a possible implementation, the fixing member is fixed to the inner wall of the tube body, and a slot for holding the sampling swab is provided on the fixing member.

[0008] In the above implementation process, a fixing part is arranged on the inner wall of the tube body, and a slot is opened on the fixing part. The sampling swab is fixed by clamping the sampling swab in the slot. The structure is simple and the operation of fixing the sampling swab is also relatively simple. It is only necessary to clamp the complete sampling swab into the slot and then break the sampling swab to fix the sampling swab part with the sampling head at a predetermined position in the sampling tube.

[0009] In a possible implementation, the fixing member includes an upper end face and a lower end face opposite to the pipe mouth of the pipe body and a fixing surface opposite to the inner wall of the pipe body, the upper end face is located between the pipe mouth and the lower end face, the slot is opened on the fixing surface, and the slot passes through the upper end face and the lower end face.

[0010] In the above implementation process, the card slot is opened on the fixed surface opposite to the inner wall of the tube body and the two ends pass through the upper end surface and the lower end surface respectively, that is, the card slot is opened horizontally. After the medical staff inserts the sampling swab into the sampling tube, the sampling swab is inserted into the card slot horizontally, and then broken according to the breaking point. The operation is convenient and the structure is simple.

[0011] In some possible embodiments, a breaking point is provided on the sampling swab, and the distance from the end face of the sampling swab close to the sampling head to the breaking point is greater than or equal to the distance from the bottom of the tube body to the upper end face of the fixing part, and less than or equal to the distance from the bottom of the tube body to the tube mouth, so that after the complete sampling swab is inserted into the slot, the breaking point of the sampling swab is located between the tube mouth of the tube body and the upper end face of the fixing part, which facilitates the breaking operation of the sampling swab.

[0012] In a possible implementation, the clamping groove extends in a direction parallel to the axis of the tube body.

[0013] In the above implementation process, the card slot is set to extend parallel to the axial direction of the tube body, so that the sampling swab is placed in the tube body along a direction parallel to the axial direction of the tube body, that is, the sampling swab is placed vertically in the tube body, thereby reserving sufficient operating space in the tube body for the automatic extraction machine or automatic sample loading machine to operate.

[0014] In a possible implementation, the cross-section of the card slot is a circle with a notch, the diameter of the circle is equal to the diameter of the sampling swab, and the length of the chord corresponding to the notch is smaller than the diameter of the sampling swab.

[0015] In the above implementation process, the inner diameter of the card slot is set equal to the diameter of the sampling swab, so that the sampling swab can be firmly fixed in the tube body, preventing the sampling swab from being separated from the fixing part and leaving the predetermined position due to external shaking and collision during transportation.

[0016] In a possible implementation, the ratio of the distance from the lower end surface of the fixing member to the bottom of the tube body to the length of the tube body is 1:2-3:4.

[0017] In the above implementation process, the ratio of the distance from the lower end surface of the fixing part to the bottom of the tube body to the length of the tube body is set to 1:2-3:4, that is, the fixing part is limited to be set close to the tube mouth of the tube body, which facilitates the fixing and breaking of the sampling swab.

[0018] In a possible implementation manner, there are multiple fixing members.

[0019] In the above implementation process, multiple fixings are arranged in the tube body, so that multiple sampling swabs can be accommodated and fixed in the tube body at the same time, that is, the sampling tube can be used for mixed sampling, and the operation of manually taking out the sampling swabs in the sampling tube multiple times is eliminated, thereby reducing high-risk infection links, thereby effectively reducing the risk of infection, simplifying the detection process, and improving the automation rate. In addition, the mixed sampling method effectively improves the detection efficiency and reduces the labor cost and the cost of protective equipment.

[0020] In a possible implementation, the fixing member is an annular body disposed along the inner wall of the tube body, and a plurality of the slots are formed on the annular body.

[0021] In the above implementation process, the fixing part is set as an annular body arranged along the inner wall of the tube body, and a plurality of slots are opened on the annular body. The plurality of slots can hold a plurality of sampling swabs so that the sampling tube can be used for mixed sampling, and the operation of manually taking out the sampling swabs in the sampling tube multiple times is eliminated, thereby reducing high-risk infection links, thereby effectively reducing the risk of infection, simplifying the detection process, and improving the automation rate. In addition, the mixed sampling method effectively improves the detection efficiency and reduces the labor cost and the cost of protective equipment.

[0022] In a possible implementation, an annular protrusion is provided on the bottom of the tube body, and the annular protrusion cooperates with the inner wall of the tube body to form an annular groove, and the annular groove is used to fix the sampling head of the sampling swab.

[0023] In the above implementation process, an annular groove is provided at the bottom of the tube to fix the sampling head of the sampling swab, and the sampling swab is placed offset to the center, which further stabilizes the sampling swab and ensures the stability of the operating space.

[0024] In a possible implementation, the sampling tube further includes a tube cover, and the tube cover is used to cover the tube opening of the tube body to seal the tube body.

[0025] In actual operation, after the sampling swab is broken and fixed at a predetermined position in the sampling tube, the tube mouth of the tube body is sealed with a tube cover to uniformly seal and manage the samples. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0032] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] In the existing virus detection process, since the broken sampling swab 200 is placed in the sampling tube at an irregular angle, the sampling swab 200 in the sampling tube needs to be manually removed before automatic sampling and sample addition, which increases the risk of infection and increases labor costs and protective equipment costs.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 A cross-sectional view of a sampling tube provided in an embodiment of the present application, Figure 2 A structural diagram of a sampling tube provided in an embodiment of the present application, Figure 3 A structural diagram of a fixing member 300 provided in an embodiment of the present application. The present application provides a sampling tube, which includes a tube body 100 and a fixing member 300. The fixing member 300 is disposed in the tube body 100 and is used to fix the sampling swab 200 at a predetermined position in the tube body 100 so that an operating space is reserved in the tube body 100.

[0035] It should be noted that the above-mentioned sampling swab 200 refers to the part with the sampling head 210 that falls freely into the sampling tube after the complete sampling swab 200 is broken.

[0036] In the above implementation process, after the medical inspector uses the sampling swab 200 to collect samples, so that the sampling head 210 of the sampling swab 200 is provided with a sample, the end of the sampling swab 200 with the sampling head 210 is inserted into the sampling tube, and the sampling swab 200 is fixed by the fixing part 300 in the sampling tube, and then the sampling swab 200 is broken at the breaking point 220, so that the sampling swab 200 remaining in the sampling tube can be fixed at a predetermined position, and the sampling swab 200 at the predetermined position is placed in the sampling tube according to a preset placement method, so as to reserve an operating space for subsequent automatic extraction or automatic sample addition. After that, when entering the laboratory testing process, there is no need to manually remove the sampling swab 200 from the sampling tube, and the sampling tube with the sampling swab 200 can be directly put on the machine for automatic extraction and sample addition operations, omitting the operation steps of manually handling the sampling swab 200, reducing the high-risk infection links, and thus effectively reducing the risk of infection, simplifying the testing process, improving the automation rate, improving the testing efficiency, and reducing the labor cost and the cost of protective equipment.

[0037] In a possible implementation, the sampling tube further includes a tube cover 600 , and the tube cover 600 is used to cover the tube opening 110 of the tube body 100 to seal the tube body 100 .

[0038] In actual operation, after the sampling swab 200 is broken and fixed at a predetermined position in the sampling tube, the tube cover 600 is used to seal the tube mouth 110 of the tube body 100 to perform unified sealing management on the sample.

[0039] The material of the tube body 100 and the tube cover 600 may be food-grade PP (Polypropylene) or other materials that meet medical requirements.

[0040] Optionally, the tube cover 600 and the tube body 100 are sealed and connected by threaded fitting, or the tube cover 600 and the tube body 100 can also be sealed and connected by snap-fitting, which is not limited in the embodiment of the present application.

[0041] The outer diameter of the tube body 100 can be reasonably designed to meet the needs of different extraction machines and sample loading machines.

[0042] In a possible implementation, the fixing member 300 is fixed to the inner wall of the tube body 100 , and a slot 310 for holding the sampling swab is provided on the fixing member 300 .

[0043] In the above implementation process, a fixing part 300 is arranged on the inner wall of the tube body 100, and a slot 310 is opened on the fixing part 300. The sampling swab 200 is fixed by clamping the sampling swab 200 through the slot 310. The structure is simple, and the operation of fixing the sampling swab 200 is also relatively simple. It is only necessary to insert the complete sampling swab 200 into the slot 310, and then break the sampling swab 200, so that the sampling swab 200 part with the sampling head 210 can be fixed at a predetermined position in the sampling tube.

[0044] The fixing member 300 may be made of various materials. The material of the fixing member 300 may be the same as the material of the tube body 100 or may be different from the material of the tube body 100 .

[0045] In one possible implementation, the fixing member 300 includes an upper end surface 320 and a lower end surface 330 opposite to the pipe mouth 110 of the pipe body 100, and a fixing surface 340 opposite to the inner wall of the pipe body 100, the upper end surface 320 is located between the pipe mouth 110 and the lower end surface 330, the slot 310 is opened on the fixing surface 340, and the slot 310 passes through the upper end surface 320 and the lower end surface 330.

[0046] In the above implementation process, the card slot 310 is opened on the fixed surface 340 opposite to the inner wall of the tube body 100 and the two ends respectively penetrate the upper end surface 320 and the lower end surface 330, that is, the card slot 310 is opened horizontally. After the medical staff inserts the sampling swab 200 into the sampling tube, the sampling swab 200 is inserted into the card slot 310 horizontally, and then broken according to the breaking point 220. The operation is convenient and the structure is simple.

[0047] In some possible embodiments, a breaking point 220 is provided on the sampling swab 200, and the distance from the end face of the sampling swab 200 close to the sampling head 210 to the breaking point 220 is greater than or equal to the distance from the tube bottom 120 of the tube body 100 to the upper end face 320 of the fixing member 300, and less than or equal to the distance from the tube bottom 120 of the tube body 100 to the tube mouth 110, so that after the complete sampling swab 200 is inserted into the card slot 310, the breaking point 220 of the sampling swab 200 is located between the tube mouth 110 of the tube body 100 and the upper end face 320 of the fixing member 300, which can facilitate the breaking operation of the sampling swab 200.

[0048] In a possible implementation, the locking slot 310 extends in a direction parallel to the axis of the tube body 100 .

[0049] In the above implementation process, the card slot 310 is set to extend parallel to the axial direction of the tube body 100, so that the sampling swab 200 is placed in the tube body 100 along the direction parallel to the axial direction of the tube body 100, that is, the sampling swab 200 is placed vertically in the tube body 100, thereby reserving sufficient operating space in the tube body 100 for the automatic extraction machine or the automatic sample loading machine to operate.

[0050] In a possible implementation, the cross section of the card slot 310 is a circle with a notch, the diameter of the circle is equal to the diameter of the sampling swab 200 , and the length of the chord corresponding to the notch is smaller than the diameter of the sampling swab 200 .

[0051] In the above implementation process, the inner diameter of the card slot 310 is set to be equal to the diameter of the sampling swab 200, so that the sampling swab 200 can be firmly clamped in the tube body 100, preventing the sampling swab 200 from being separated from the fixing part 300 and leaving the predetermined position due to external shaking and collision during transportation.

[0052] In a possible implementation, the ratio of the distance from the lower end surface 330 of the fixing member 300 to the tube bottom 120 of the tube body 100 to the length of the tube body 100 is 1:2-3:4.

[0053] In the above implementation process, the ratio of the distance from the lower end surface 330 of the fixing member 300 to the tube bottom 120 of the tube body 100 to the length of the tube body 100 is set to 1:2-3:4, that is, the fixing member 300 is limited to be positioned close to the tube mouth 110 of the tube body 100, so as to facilitate operations such as fixing and breaking the sampling swab 200.

[0054] Mixed sampling is a method of testing after multiple samples are collected. The mixed sampling method can greatly improve the detection efficiency and is of great significance for large-scale virus detection, such as large-scale nucleic acid screening detection of new coronavirus pneumonia. The mixed sampling sampling kit consists of multiple sampling swabs 200, a sampling tube and a preservation solution. The specific mixed sampling process is as follows: medical staff take a single sampling swab 200 to collect samples separately. After each sampling is completed, it is placed in the sampling tube and soaked in the preservation solution to complete multiple sampling actions, and the corresponding collection records are made. After the mixed sampling is completed, it is transported to the laboratory through the sample preservation box to enter the detection process, and then the cover is opened for detection.

[0055] For mixed sampling, in the existing operation, multiple sampling swabs 200 are placed irregularly in a storage tube, so that there is no operating space reserved in the sampling tube for the extraction head or the sampling head of the subsequent automatic extractor or the automatic sampler to extend into the sampling tube for extraction or sample addition. Therefore, the sampling swab 200 in the sampling tube needs to be manually taken out before automatic extraction or sample addition. Manually taking out the sampling swab 200 in the sampling tube many times greatly increases the risk of infection, reduces the detection efficiency, and increases the labor cost and the cost of protective equipment.

[0056] In a possible implementation, there are multiple fixing members 300 .

[0057] In the above implementation process, a plurality of fixing parts 300 are arranged in the tube body 100, so that a plurality of sampling swabs 200 can be accommodated and fixed in the tube body 100 at the same time, that is, the sampling tube can be applied to a mixed sampling method, and the operation of manually taking out the sampling swabs 200 in the sampling tube multiple times is eliminated, thereby reducing high-risk infection links, thereby effectively reducing the risk of infection, simplifying the detection process, and improving the automation rate. In addition, the mixed sampling method effectively improves the detection efficiency and reduces the labor cost and the cost of protective equipment.

[0058] In some embodiments, multiple fixing members 300 are arranged in an array along the inner wall of the tube body 100, so that the multiple fixing members are arranged at the same height in the tube body 100. Multiple sampling swabs 200 are arranged vertically in the tube body 100 near the inner wall of the tube body 100, forming an operating space in the middle to facilitate subsequent automatic extraction or sample addition operations.

[0059] In one possible implementation, see Figure 1 and Figure 3 The fixing member 300 is an annular body arranged along the inner wall of the tube body 100 , and a plurality of slots 310 are opened on the annular body.

[0060] In the above implementation process, the fixing part 300 is set as an annular body arranged along the inner wall of the tube body 100, and a plurality of slots 310 are opened on the annular body. The plurality of slots 310 can hold a plurality of sampling swabs 200 so that the sampling tube can be applied to a mixed sampling method, and the operation of manually taking out the sampling swabs 200 in the sampling tube multiple times is eliminated, thereby reducing high-risk infection links, thereby effectively reducing the risk of infection, simplifying the detection process, and improving the automation rate. In addition, the mixed sampling method effectively improves the detection efficiency and reduces the labor cost and the cost of protective equipment.

[0061] In some embodiments, multiple slots 310 on the annular body are arranged in a circumferential array, and multiple sampling swabs 200 inserted in the slots 310 are vertically arranged in the tube body 100 close to the inner wall of the tube body 100, forming an operating space in the middle to facilitate subsequent automatic extraction or sample addition operations.

[0062] In a possible implementation, an annular protrusion 400 is provided on the tube bottom 120 of the tube body 100 , and the annular protrusion 400 cooperates with the inner wall of the tube body 100 to form an annular groove 500 , and the annular groove 500 is used to fix the sampling head 210 of the sampling swab 200 .

[0063] In the above implementation process, an annular groove 500 is provided on the tube bottom 120 to fix the sampling head 210 of the sampling swab 200 , and the sampling swab 200 is placed offset toward the center, which further stabilizes the sampling swab 200 and ensures the stability of the operating space.
