[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0031] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.
[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example
[0034] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-suspension specimen bag, including an outer bag 1 and an inner bag 2. The inner bag 2 is placed inside the outer bag 1, and the outer side of the upper opening is integrated with the opening of the outer bag 1, thereby forming two spaces: a protective space of the outer bag 1 (without any contents between it and the inner bag 2), and a fixative specimen containment space of the inner bag 2.
[0035] The outer bag 1 has a tissue fluid injection port 3 near the opening. The inner bag 2 has a double-layer structure design. Along the bottom line of the inner layer of the inner bag 2, there is a one-way anti-suspension valve 5 between the two vertical sides inside the inner bag 2. The opening of the outer bag 1 is located outside the opening of the inner bag 2 and has a sealing structure 6.
[0036] The device features a one-way anti-suspension valve 5 inside the inner bag. When the specimen tissue and fixative rise to this level, the one-way anti-suspension valve 5 will block the specimen, allowing the fixative level to continue rising. This effectively prevents the specimen tissue from suspending during transportation and ensures uniform soaking of the specimen. Example
[0037] like Figures 1-4 As shown, the inner port of the tissue fluid injection port 3 is connected to the outer layer of the inner bag 2, and the outer end is threadedly connected to the cap 31, which is equipped with two one-way valves 32. The output direction of the one-way valves 32 is towards the inside of the outer bag 1. This cap 31 makes it convenient for users to open and close the injection port to ensure the airtightness of the specimen bag during transportation and storage. In addition, the one-way valve 32 inside the injection port ensures that the fixative can only be injected into the bag in one direction, effectively preventing the backflow and overflow of the liquid.
[0038] The permeation hole 4 connects the inner and outer layers of the inner bag 2.
[0039] The cross-section and sides of the one-way anti-suspension valve 5 are both crescent-shaped, and the longer side of the one-way anti-suspension valve 5 is attached to the inner layer of the inner bag 2. The one-way anti-suspension valve 5 is located in the middle of the inner layer of the inner bag 2 and faces upward. The crescent-shaped structure and the tight fit with the inner bag 2 ensure that the specimen tissue will not be suspended during transportation, thus maintaining its soaking uniformity and integrity.
[0040] The opening of the outer bag 1 connects to the opening of the inner bag 2.
[0041] The sealing structure 6 includes a self-sealing double rib 61, which is located at the opening of the outer bag 1 outside the opening of the inner bag 2. The outer side of the self-sealing double rib 61 is heat-sealed at the opening of the outer bag 1. Users can simply press the double rib to close or open the specimen bag. In addition, the outer side of the double rib is also heat-sealed to ensure the tightness and security of the specimen bag when closed (once the specimen bag is sealed with a specimen, it cannot be resealed after being torn open again, thus ensuring the safety of the specimen).
[0042] The outer bag 1 has a transparent saddle bag 11 on its outer side. The transparent saddle bag 11 on the outer side of the outer bag 1 allows the user to observe the internal situation without opening the specimen bag, which is convenient for management and monitoring.
[0043] The utility model discloses a work flow: when using this anti-suspension specimen bag, the user first injects necessary fixing liquid into the outer layer of the inner bag 2 by opening the cover 31 of the tissue fluid injection port 3, and because of the existence of the one-way valve 32, the fixing liquid can only flow in one direction and inject into the bag, ensuring that the specimen is soaked evenly; at the same time, the fixing liquid enters the inner layer of the inner bag 2 from the outer layer of the inner bag 2 through the permeation hole 4, and the user puts the specimen to be preserved into the inner layer of the inner bag 2 by expanding the inner bag 2 on one side of the one-way anti-suspension flap 5, and then the one-way anti-suspension flap 5 effectively prevents the suspension of the specimen tissue, and then the self-sealing double bone strip 61 is pressed to seal, and the excess part of the outer bag is heat-sealed at the same time, when the specimen bag needs to be opened, the user only needs to remove the heat-sealed part, and the specimen bag can be opened by pulling the self-sealing double bone strip 61.
[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
