Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a disposable pathological specimen mother-and-child bag. Background Art

[0002] Pathological specimens refer to tissue or cell samples obtained from patients for pathological research and diagnosis. Common pathological specimens include biopsy tissues, surgical resection specimens, cell smears, etc. The type and extent of the disease can be determined by observing and analyzing pathological specimens.

[0003] Although there are many specimen mother-child bags in clinical practice, the actual clinical use effects of the products vary greatly. The existing specimen mother-child bags still have the following problems in clinical use:

[0004] 1. Sealing difficulties: Existing pathology specimen mother-and-child bags are mostly sealed with press-fit buckles at the bag opening and between the mother bag and the child bag. The difficulty in pressing makes it impossible to completely close the buckle. The vibration during transportation or storage can easily cause the buckle to open and fall off, causing the fixative to tip over or contact contamination, resulting in specimen denaturation, pollution of the surrounding environment, and increasing the risk of excessive exposure of operators to formalin.

[0005] 2. Interval failure: The existing pathology specimen mother-and-child bags are mostly sealed with press-fit buckles. The difficulty in pressing makes it impossible to completely close the buckles, and the buckles are easy to fall off during transportation and use, resulting in the inability to effectively preserve the fixative for a long time, and increasing the risk of excessive exposure of operators to formalin.

[0006] 3. The seal on the top of the bag is too small: The seal on the top of some specimen mother-and-child bags is too small. When the bag is filled with a large volume of fixative and specimens, it is easy to deform, break and leak, causing specimen corruption, environmental pollution and cross infection.

[0007] 4. Repeated contact with fixative: When testing samples, testers need to open the specimen bag multiple times. The existing pathology specimen bag cannot effectively separate the fixative and the sample, causing personnel to contact the fixative multiple times, increasing health hazards.

[0008] 5. Incomplete storage of fixative: After use, the existing specimen bag products are not completely sealed and cannot effectively store the fixative, resulting in leakage of the fixative, causing unnecessary environmental pollution and personal harm. Utility Model Content

DETAILED DESCRIPTION

[0032] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

[0033] [Example 1]

[0034] Reference Figure 1 , 3 As shown in Figures 4 and 5, the utility model comprises a disposable mother-child bag for pathological specimens, comprising a child bag body 3, a valve component 4 being fixed at one end of the child bag body 3, a mother bag body 2 being fixed at the other end of the valve component 4, a locking component 1 being provided at the upper end of the mother bag body 2, and the other end of the mother bag body 2 being separated from the child bag body 3 by a spacer seal 5; the locking component 1 comprises a compression buckle 101, and a sealing buckle 102 is clamped at the outer edge of the compression buckle 101, and the upper compression buckle 101 is closed by sliding the sealing buckle 102. The valve component 4 is used to effectively separate the fixative and the specimen tissue. When the valve component is in a closed state before use, the fixative in the sub-bag cannot flow out. The locking component 1 can effectively keep the bag sealed. The compression buckle 101 and the sealing buckle 102 of the locking component 1 can be effectively closed to avoid deformation, damage and leakage of the bag when a large volume of fixative and specimen are contained. The valve component 4 is provided with a mesh channel 401, and the opening or closing of the mesh channel 401 is controlled by the handle 402. The coordinated design of the valve component 4 and the locking component 1 ensures that the bag is more tightly sealed during use, prevents the fixative from tipping over or contact contamination, and reduces the risk of specimen denaturation and environmental pollution.

[0035] The valve member 4 can effectively isolate the fixing liquid in a closed state to prevent the fixing liquid from flowing out. By controlling the opening and closing of the valve, it is ensured that the fixing liquid enters the mother bag body 2 only when needed, thereby achieving long-term effective preservation of the fixing liquid.

[0036] At the same time, after use, by closing the valve component 4, the fixing liquid can be effectively stored to prevent leakage of the fixing liquid, avoid the problem of fixing liquid leakage caused by incomplete sealing, and reduce environmental pollution and personnel hazards.

[0037] The sealing buckle 102 is a limit buckle. By sliding the sealing buckle 102 to close the upper compression buckle 101, the bag body can be effectively kept sealed, avoiding deformation, damage and leakage of the bag body when a large volume of fixative and specimens are loaded. At the same time, the operator closes the compression buckle through the sealing buckle of the locking component 1, opens the valve to allow the fixative to flow between the upper and lower bag bodies, avoiding direct contact with the fixative, reducing the risk of multiple contacts with the fixative, and reducing health hazards. During the entire process of use, medical workers are prevented from having adverse reactions such as skin damage caused by direct contact with the fixative, and the specimen and the fixative can be separated and accessed without direct contact with the fixative. The sealing buckle 102 is provided with a positioning arc portion 103 protruding outward. The top of the compression buckle 101 is provided with an easy opening 104.

[0038] The valve component 4 includes a valve body 400, on which a knob 402 is mounted, a straight mesh channel 401 is arranged inside the valve body 400, a grid 403 is arranged inside the mesh channel 401, and flat arc grooves 404 are arranged at both ends of the valve body. The mesh channel 401 and the knob 402 are used to control the flow of the fixative, so that the separation of the fixative and the specimen tissue is more effective.

[0039] The side edges of the mother bag body 2, the sub-bag body 3, the press-fit buckle 101 and the bottom of the sub-bag body 3 are all provided with a sealing edge 10, and the press-fit buckle 101 and one side sealing edge 10 of the sub-bag body 3 are provided with a hanging hole 6. The side sealing edge 10 of the sub-bag body 3 is provided with a liquid filling port 7 and an easy-tear opening 8, and the sub-bag body 3 is filled with a fixing liquid, which is a formalin solution.

[0040] [Example 2]

[0041] Reference Figure 2 As shown, the bottom of the sub-bag body 3 is a folded edge seal 9, and the strength and durability of the bag body are enhanced by the edge seal 10 and the folded edge seal 9 structural design. The bag body is further prevented from deformation, damage and leakage when a large volume of fixative and specimens are contained. Even when a large volume of fixative and specimens are contained, the bag body can maintain its shape, thereby avoiding specimen corruption, environmental pollution and cross infection, and ensuring safe storage of specimens and fixatives. The remaining technical solutions are consistent with the first embodiment.

[0042] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific usage methods.
