Description

Technical Field

[0001] The present invention relates to the technical field of in vitro diagnostic medical devices, and particularly to a test tube structure that does not require opening the cap. Background Art

[0002] In the current in vitro diagnostic industry, clinical samples are generally collected in sample cups and then poured into test tubes and sealed with plastic caps for convenient subsequent storage and transportation. Staff must remove the caps of the test tubes to perform tests. Such operations are cumbersome, which reduces the work efficiency of medical staff, and there is also a risk of biological contamination caused by the overflow of samples from the test tubes.

[0003] There are also test tubes that do not require opening the cap. Generally, a single-layer sealing layer made of materials such as plastic film or metal foil is designed in the hollow cap to play a sealing role; or a rubber stopper is clamped on the hollow cap, a round hole is provided in the center of the rubber stopper, and a silicone sheet is arranged in the round hole to play a sealing role; or two sealing layers are arranged on the hollow cap, one is an airtight layer made of materials such as plastic film or metal foil, and the other is a sealing layer that reversibly closes the puncture port and is composed of elastic or flexible materials.

[0004] These solutions either easily cause the sealing layer to clamp the puncture needle during puncture, and when sucking the sample, the test tube is lifted together, causing splashing of the sample in the test tube, or the silicone sheet fits tightly with the sampling needle, and it is impossible to ensure the air circulation inside and outside the tube during sampling, resulting in a pressure difference and low accuracy of the sucked sample volume, or it is difficult for the puncture needle to penetrate the test tube, resulting in malfunctions such as needle collision and damage to the instrument, or it is easy to generate puncture debris and enter the puncture needle, causing needle blockage, sample contamination, etc. Summary of the Invention

[0005] The purpose of the present invention is to provide a test tube structure that does not require opening the cap, aiming to solve the problems that the existing test tubes that do not require opening the cap are difficult to penetrate and there are situations of pinching the needle and non-ventilation, resulting in a reduction in the efficiency of sucking samples.

[0006] To achieve the above purpose, the present invention provides a test tube structure that does not require opening the cap, including a test tube body, a cap body, and a membrane-breaking member. The test tube body has a first groove. The cap body includes a rotating cap and a sealing film. The rotating cap has a first through hole and a buckle hole. The number of buckle holes is multiple, and the multiple buckle holes are distributed around the cap body. The sealing film is fixedly connected to the rotating cap and covers the first through hole. The rotating cap and the test tube body are detachably connected, and the test tube body is located in the first through hole. The membrane-breaking member includes an outer ring and an inner ring. The outer ring has a plurality of buckle protrusions, and the plurality of buckle protrusions are distributed on the outer ring and are respectively located in the plurality of buckle holes. The inner ring has a reserved groove. The inner ring and the outer ring are fixedly connected and are located inside the outer ring. The reserved groove is close to the sealing film.

[0007] Wherein, one end of the test tube body away from the lid body is a cone.

[0008] Wherein, the test tube body includes a test tube body main body and a plurality of rib plates. The plurality of rib plates are fixedly connected to the test tube body main body and are located on a side of the test tube body away from the lid body.

[0009] Wherein, the test tube body further includes a rubber sheet. The rubber sheet has a second through hole. The rubber sheet is fixedly connected to the test tube body main body and covers the first groove.

[0010] Wherein, the shape of the second through hole can be any one of a straight shape, a C shape, a cross shape, an X shape, and a rice shape.

[0011] Wherein, the lid body has vertical stripes, and the vertical stripes are distributed around the lid body.

[0012] Wherein, the inner ring has a chamfer, and the chamfer is located on a side of the inner ring close to the sealing film.

[0013] Wherein, the outer ring has a plurality of second grooves, and every two of the second grooves are distributed on both sides of the buckle protrusion.

[0014] For a structure of a test tube that does not require opening the lid according to the present invention, a liquid sample can be placed in the first groove. The plurality of buckle holes are distributed around the lid body. The sealing film is fixedly connected to the rotary lid and is used to seal the first groove to prevent the sample inside from being polluted by the external environment. The rotary lid and the test tube body are detachably connected, which can further enhance the sealing effect of the sealing film. The test tube body is located in the first through hole. The plurality of buckle protrusions are distributed on the outer ring to ensure that the film-breaking member is buckled on the rotary lid without slipping. The inner ring and the outer ring are fixedly connected. The reserved groove is close to the sealing film. When the punch moves downward directly above the film-breaking member, the punch pushes the film-breaking member downward at this time. The inner ring cuts the sealing film below it during the downward movement and makes the sealing film not fall into the first groove. When the sampling needle enters the inner cavity of the test tube to suck the sample, the sampling needle basically does not contact the sealing film. By providing the film-breaking member to remove the sealing film in advance and preventing the sealing film from falling into the first groove, the sampling needle can conveniently enter the first groove for sampling without getting stuck, thereby solving the problems of difficult piercing of the existing test tube without opening the lid, pinching the needle, and poor ventilation, which lead to a reduction in the efficiency of sucking the sample. In addition, when performing on-machine detection, it is not necessary to frequently open and remove the lid. There is almost no impact on the sampling needle, which can reduce the requirements for the structure, strength, size, etc. of the sampling needle. The sampling needle will not stick to film impurities. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the present invention provides a test tube structure that does not require opening the lid, comprising:

[0025] A test tube body 1, a lid body 2 and a film-breaking member 3. The test tube body 1 has a first groove 11. The lid body 2 includes a rotary lid 21 and a sealing film 22. The rotary lid 21 has a first through hole 23 and a snap hole 24. The number of the snap holes 24 is multiple, and the multiple snap holes 24 are distributed around the lid body 2. The sealing film 22 is fixedly connected to the rotary lid 21 and covers the first through hole 23. The rotary lid 21 and the test tube body 1 are detachably connected. The test tube body 1 is located within the first through hole 23. The film-breaking member 3 includes an outer ring 31 and an inner ring 32. The outer ring 31 has a plurality of snap protrusions 33. The plurality of snap protrusions 33 are distributed on the outer ring 31 and are respectively located within the plurality of snap holes 24. The inner ring 32 has a reserved groove 34. The inner ring 32 and the outer ring 31 are fixedly connected and are located inside the outer ring 31. The reserved groove 34 is close to the sealing film 22.

[0026] In this embodiment, the test tube body 1 has a first groove 11 in which a liquid sample can be placed. The cover body 2 includes a rotating cover 21 and a sealing film 22. The rotating cover 21 has a first through hole 23 and a snap hole 24. The number of the snap holes 24 is multiple, and the multiple snap holes 24 are distributed around the cover body 2. The sealing film 22 is fixedly connected to the rotating cover 21 and covers the first through hole 23. The material of the sealing film 22 can be a plastic film, a metal foil, a rubber film, etc., and is used to seal the first groove 11 to prevent the sample inside from being polluted by the external environment. The rotating cover 21 and the test tube body 1 are detachably connected, and the detachable connection method can be a threaded connection, an interference extrusion connection, or the mutual attraction of magnetic materials, etc., which can further enhance the sealing effect of the sealing film 22. The test tube body 1 is located within the first through hole 23. The film-breaking member 3 includes an outer ring 31 and an inner ring 32. The outer ring 31 has a plurality of snap protrusions 33. The plurality of snap protrusions 33 are distributed on the outer ring 31 and are respectively located within the plurality of snap holes 24, ensuring that the film-breaking member 3 is buckled on the rotating cover 21 without slipping off. The inner ring 32 has a reserved groove 34. The inner ring 32 and the outer ring 31 are fixedly connected and are located inside the outer ring 31. The reserved groove 34 is close to the sealing film 22. Before detecting the test tube containing the sample on the production line, through a specific clean punch or a puncturing and opening mechanism on the pre-treatment module of the production line, it moves downward directly above the film-breaking member 3. At this time, the punch pushes the film-breaking member 3 downward. During the downward movement of the inner ring 32, it cuts open the sealing film 22 below it and keeps the connection between the sealing film 22 and the rotating cover 21 at the reserved groove 34, so that the sealing film 22 will not fall into the first groove 11. The inner ring 32 after film-breaking can be designed in two states. One is to remain in the lowest state during the downward movement and cannot rebound to the initial position as the punch on the production line moves upward. The other is to rebound to the initial position as the punch moves upward. When the sampling needle enters the inner cavity of the test tube to suck the sample, the sampling needle basically does not contact the sealing film 22. By providing the film-breaking member 3 to remove the sealing film 22 in advance and preventing the sealing film 22 from falling into the first groove 11, the sampling needle can conveniently enter the first groove 11 for sampling without getting stuck, thus solving the problems of difficult piercing of the existing non-opening test tube, pinching of the needle, airtightness problems, and reduced efficiency of sucking the sample.

[0027] Further, one end of the test tube body 1 away from the cover body 2 is a cone 15.

[0028] In this embodiment, the conical shape of the lower part of the test tube can raise the height of the urine to the detection height of the fully automatic urine analyzer when the amount of urine is too small, enabling the detection to proceed smoothly.

[0029] Furthermore, the test tube body 1 includes a test tube body main body 12 and a plurality of rib plates 13. The plurality of rib plates 13 are fixedly connected to the test tube body main body 12 and are located on the side of the test tube body 1 away from the cover body 2.

[0030] In this embodiment, the rib plates 13 are used to increase the strength of the conical part, making the bottom of the test tube body 1 not easily damaged. At the same time, it is also convenient to cooperate with the box body with a right groove to stably place the test tube.

[0031] Furthermore, the test tube body 1 further includes a rubber sheet 14. The rubber sheet 14 has a second through hole. The rubber sheet 14 is fixedly connected to the test tube body main body 12 and covers the first groove 11.

[0032] In this embodiment, the rubber sheet 14 can still flexibly seal the test tube mouth after the sealing film 22 is punctured, preventing the liquid inside from leaking out. The second through hole facilitates the sampling needle to pass through.

[0033] Furthermore, please refer to Figure 5 , the shape of the second through hole can be any one of a linear shape, a C shape, a cross shape, an X shape, a * shape, and a rice shape.

[0034] Furthermore, the cover body 2 has vertical stripes 25. The vertical stripes 25 are distributed around the cover body 2.

[0035] In this embodiment, the vertical stripes 25 can increase the friction between the user and the cover body 2, thereby enabling the user to more easily rotate the cover body 2 to fasten it to the test tube body 1.

[0036] Furthermore, the inner ring 32 has a chamfer 35. The chamfer 35 is located on the side of the inner ring 32 close to the sealing film 22.

[0037] In this embodiment, the chamfer 35 facilitates inserting the inner ring 32 into the first through hole 23 without generating too much resistance.

[0038] Furthermore, the outer ring 31 has a plurality of second grooves 36. Every two of the second grooves 36 are distributed on both sides of the buckle protrusion 33.

[0039] In this embodiment, when the film-breaking member 3 is pressed downwards, the buckle protrusion 33 will move inwards a small distance under the support of the cover body 2. Increasing the second groove 36 can reduce the obstruction of the parts around the buckle protrusion 33 to the movement of the buckle protrusion 33, making it easier to press down the film-breaking member 3.

[0040] The working principle and usage process of the present invention: Please refer to Figure 1 and Figure 3 , after the present invention is installed, a sample is placed in the first groove 11 through a sampling cup, and then the sealing film 22 and the test tube body 12 are connected to seal the first groove 11. When in use, the film-breaking member 3 is pressed down manually or by a punch on a production line, so that the inner ring 32 penetrates through the sealing film 22 to open the first groove 11, and then a sampling needle can be inserted to aspirate the sample. This enables the urine centrifuge tube to be applicable to a fully automatic sample detection production line, reducing the participation of medical staff in the sample detection process, effectively protecting the safety of medical staff, and improving the work efficiency of medical staff. In addition, it also prevents the sampling needle from being unable to enter the test tube smoothly due to excessive resistance, and prevents impurities in the sealing film 22 from entering the sampling needle and causing a needle blockage failure. At the same time, the test tube can achieve hard or flexible sealing before and after sample detection, effectively preventing the harm of aerosol pollution.

[0041] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
