Description

Technical Field

[0001] This utility model belongs to the field of specimen preservation technology, and in particular relates to a specimen dispensing bottle. Background Technology

[0002] In biological research and clinical examinations, tissue sections are frequently required, and tissue fixation is a crucial step in tissue section preparation. The obtained tissue specimens need to be preserved in specimen bottles. The traditional method involves directly filling the specimen bottle with a certain amount of fixative solution and immersing the tissue specimen in it. During this process, the user inevitably comes into contact with the fixative solution, and any leakage of the fixative solution's odor can also have a certain impact on the surrounding environment and affect the user's health.

[0003] Although there are structures in the beverage industry that separate concentrated liquids, powders and other raw materials from solvents, such as the press-type ready-to-drink bottle cap disclosed in Chinese utility model patent CN207791580U, which seals concentrated liquids, powders and other raw materials in the bottle cap, the solution or powder can be punctured by moving the piercing part downwards to allow it to fall into the bottle and mix, thus achieving the purpose of dispensing.

[0004] However, for fixatives of tissue specimens, impurities are not allowed to enter the bottle, otherwise it will affect the subsequent research or examination of tissue sections. The existing packaging structure cannot meet the requirements for the preservation of tissue specimens. Utility Model Content

[0005] The technical objective of this invention is to provide a specimen dispensing bottle with good sealing properties, ensuring that the user does not come into contact with the tissue fixation fluid during operation, preventing odor leakage, protecting the user's health, and effectively preventing impurities from entering the specimen body.

[0006] To solve the above-mentioned technical problems, this utility model is implemented as follows: a specimen bottle includes a specimen bottle body, a top cover, a filter housing, and a puncture structure. The top cover is fixed to the opening of the specimen bottle body. A sealing structure for sealing a fixative is provided on the inner side of the top cover. The puncture structure is disposed opposite to the sealing structure. The filter housing is disposed below the sealing structure. A partition is provided inside the filter housing. Fixative filtration holes and vent holes are respectively provided on the filter housing on both sides of the partition. The fixative filtration holes are disposed in the middle of the filter housing and opposite to the puncture structure. The vent holes are disposed on the side of the filter housing.

[0007] Furthermore, the filter housing is provided with a plurality of partitions, the vent is disposed between the partitions and the inner wall of the filter housing, and the fixed liquid filter hole is disposed between the plurality of partitions.

[0008] Furthermore, the area of ​​each of the vent holes is larger than the area of ​​each of the stationary liquid filter holes.

[0009] Furthermore, the filter housing is disposed inside the specimen bottle, and the lower end of the upper cover is fixedly connected to the inside of the opening of the specimen bottle. The filter housing is connected to the lower end of the upper cover. The filter housing can be removed from the upper cover.

[0010] Furthermore, the sealing structure includes a sealing membrane and a sealing top cover. The sealing membrane is fixed to the lower part of the upper cover, and the sealing top cover is disposed at the upper end of the upper cover. The piercing structure is disposed between the sealing membrane and the sealing top cover, and the sealing membrane is pierced by pressing the sealing top cover against the piercing structure.

[0011] Furthermore, the sealing top cover is made of a flexible material, and its side is connected to the upper cover. The upper end of the piercing structure contacts the sealing top cover, and the lower end of the piercing structure contacts the sealing membrane. After pressing the sealing top cover, the piercing structure pierces the sealing membrane downwards, allowing the tissue fixative between the sealing membrane and the sealing top cover to enter the specimen bottle through the fixative filter hole.

[0012] Furthermore, the upper end of the cover is open, the sealing top cover is fixed to the inner side of the upper part of the cover, the upper end of the cover has an inclined surface, and the sealing top cover is lower than the higher end of the inclined surface.

[0013] Furthermore, the sealing top cover is threadedly connected to the upper cover.

[0014] Furthermore, the puncture structure includes a puncture disc and a puncture rod, the puncture disc is fixed to the lower end of the puncture rod, and the lower side of the puncture disc is provided with a plurality of puncture teeth.

[0015] Furthermore, the puncture disc includes a rectangular puncture disc body, and at least two intersecting ribs are provided on the inner side of the puncture disc body. The lower end of the puncture rod is fixedly connected to the ribs, and the puncture teeth are provided on the lower side of both the puncture disc body and the ribs.

[0016] Furthermore, the upper end of the puncture rod is provided with a straightening wing plate, and the distance from the side of the straightening wing plate to the puncture rod gradually increases from top to bottom.

[0017] Compared with the prior art, the beneficial effects of the specimen dispensing bottle in this utility model are as follows:

[0018] The specimen bottle has a filter housing on the lower side of the sealed structure. The filter housing on both sides of the partition is provided with fixative filter holes and vent holes, respectively. After the seal is punctured, the tissue fixative enters the specimen bottle through the fixative filter holes, preventing the seal from falling into the specimen bottle after being punctured. Air in the specimen bottle can enter the top cover through the vent holes, allowing the tissue fixative to enter the specimen bottle more smoothly. Therefore, the fixative filter holes can be made smaller, resulting in better filtration.

[0019] The top cover is pre-filled with tissue fixative, which can prevent liquid evaporation, ensure the subsequent tissue fixation effect, prevent fixative evaporation from polluting the air, and prevent users from smelling liquid odor and directly contacting fixative during use, thus protecting the user's health.

[0031] Example 1:

[0032] See Figure 1-3 In this embodiment, the specimen bottle includes: a specimen bottle body 1, a top cover 2, a filter housing 7, and a puncture structure 6. The top cover 2 is fixed at the opening of the specimen bottle body 1. A sealing structure for sealing the fixative is provided on the inner side of the top cover 2. The puncture structure 6 is arranged opposite to the sealing structure. The filter housing 7 is arranged below the sealing structure. A plurality of fixative filter holes 702 are opened at the bottom of the filter housing 7. After the puncture structure 6 punctures the sealing structure, the tissue fixative in the sealing structure will enter the specimen bottle body 1 through the fixative filter holes 702. The punctured sealing structure is blocked by the fixative filter holes 702 to prevent impurities from entering the specimen bottle body 1.

[0033] A tissue fixative is pre-filled in a certain proportion in the sealed structure inside the top cover 2. The specimen bottle 1 is filled with water. After the tissue is placed in the water in the specimen bottle 1, the pre-filled tissue fixative flows into the water through the puncture of the sealed structure. Taking formalin fixative as an example, formalin fixative mixed with water becomes 10% neutral formalin, which plays a role in fixing the tissue specimen. The two are packaged separately to avoid the user coming into contact with formalin / fixative and to prevent odor leakage, thus protecting the user's health.

[0034] The specimen bottle 1 is made of transparent material and has a scale 3 on the specimen body. After the tissue is placed in the water in the specimen bottle 1, the volume of the tissue is calculated by the change in the volume of water before and after placement. After the volume is measured, the formalin fixative is released into the water by puncturing the sealing structure to fix the tissue. This is mainly for scientific research. If the volume measurement is not required in clinical practice, the formalin fixative can be released into the water directly by puncturing the sealing structure to fix the tissue.

[0035] The filter housing 7 is installed inside the specimen bottle 1. The lower end of the upper cover 2 is fixedly connected to the inside of the opening of the specimen bottle 1. The filter housing 7 is connected to the lower end of the upper cover 2, and the two can be disassembled.

[0036] The sealing structure in this embodiment includes a sealing membrane 5 and a sealing top cover 4. The sealing membrane 5 is fixed to the lower part of the upper cover 2, and the sealing top cover 4 is disposed at the upper end of the upper cover 2. The puncturing structure 6 is disposed between the sealing membrane 5 and the sealing top cover 4. The sealing membrane 5 is punctured by pressing the puncturing structure 6 with the sealing top cover 4.

[0037] The sealing top cover 4 is made of flexible material. Its side is fixedly connected to the upper cover 2. The sealing top cover 4 can be fixed to the upper cover 2 by adhesive bonding or interference fit. It can both press down on the piercing structure 6 and seal the formalin fixative filled inside the upper cover 2. The upper end of the piercing structure 6 contacts the sealing top cover 4, and the lower end contacts the sealing membrane 5. After pressing the sealing top cover 4, the piercing structure 6 pierces the sealing membrane 5, and the tissue fixative between the sealing membrane 5 and the sealing top cover 4 enters the specimen bottle 1 through the fixative filter hole 702. The sealing top cover 4 can also be integrally formed with the upper cover 2.

[0038] The upper cover 2 has an open top, and the sealing top cover 4 is fixed to the inner side of the upper part of the upper cover 2. The upper end of the upper cover 2 has an inclined surface 201, and the sealing top cover 4 is lower than the higher end of the inclined surface 201. When the user holds the specimen bottle 1, their thumb can just press the sealing top cover 4, which is ergonomic. The inclined surface can effectively prevent the sealing top cover 4 from being accidentally pressed, making it more convenient for transportation and storage. In this embodiment, the shape of the upper part of the upper cover 2 can be circular or non-circular.

[0039] See Figure 4 The puncture structure 6 includes a puncture disc 601 and a puncture rod 602. The puncture disc 601 is fixed to the lower end of the puncture rod 602, and the lower side of the puncture disc 601 is provided with several puncture teeth 604. The upper end of the puncture rod 602 is provided with a straightening wing plate 603. The distance from the side of the straightening wing plate 603 to the puncture rod 602 gradually increases from top to bottom. The straightening wing plate 603 can prevent the puncture rod 602 from shaking inside the upper cover 2 during the falling process, making it more convenient to use. Moreover, it is also very convenient to place the puncture structure 6 inside the upper cover 2 during the processing.

[0040] The puncture disc 601 includes a rectangular puncture disc body 6011, and at least two intersecting ribs 6012 are provided on the inner side of the puncture disc body 6011. The lower end of the puncture rod 602 is fixedly connected to the ribs 6012. Puncture teeth 604 are provided on the lower side of both the puncture disc body 6011 and the ribs 6012. This gives the puncture disc 601 a large puncture area, allowing the sealing membrane 5 to be punctured over a large area, which is more conducive to the downward flow of tissue fixation fluid.

[0041] See Figure 5 The filter housing 7 is provided with a partition 701. The filter housing 7 on both sides of the partition 701 is provided with a fixed liquid filter hole 702 and a vent hole 703 respectively. The fixed liquid filter hole 702 is located in the middle of the filter housing 7 and is opposite to the puncture structure 6. The vent hole 703 is located on the side of the filter housing 7.

[0042] In this embodiment, the filter housing 7 is provided with multiple partitions 701. A vent 703 is provided between the partition 701 and the inner wall of the filter housing 7. A plurality of fixed liquid filter holes 702 are provided at the bottom of the filter housing 7 between the multiple partitions 701. The area of ​​each vent 703 is larger than the area of ​​each fixed liquid filter hole 702.

[0043] Formalin fixative is pre-filled between the sealing membrane 5 inside the upper cover 2 and the sealing top cover 4. The specimen bottle 1 is filled with water. The upper cover 2 is opened, and the tissue is placed into the water in the specimen bottle 1. The upper cover 2 is then closed at the opening at the top of the specimen bottle 1. The volume of the tissue is calculated by measuring the change in water volume before and after placement. After measuring the volume, the sealing top cover 4 is pressed to puncture the sealing membrane 5 with the puncture teeth 604 of the puncture structure 6, allowing the formalin fixative to flow into the water and fix the tissue. If volume measurement is not required in clinical practice, the sealing top cover 2 can be pressed directly to puncture the sealing membrane 5 with the puncture teeth 604 of the puncture structure 6, allowing the formalin fixative to flow into the water and fix the tissue. The tissue fixative enters the specimen bottle 1 through the fixative filter hole 702, preventing the sealing membrane 5 from being punctured and falling into the specimen bottle 1, thus ensuring accurate testing.

[0044] Example 2

[0045] See Figure 6 In this embodiment, the sealing top cover 4 is threadedly connected to the upper cover 2. The upper end of the piercing structure 6 can be fixedly connected to the sealing top cover 4 or it can be movably connected. By rotating the sealing top cover 4, the piercing structure 6 gradually moves downward and pierces the sealing film 5.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
