Description

Technical Field

[0001] The utility model relates to the field of biological technology devices, specifically to a device for preserving biological tissues, and more specifically to a device for storing umbilical cord tissues. Background Art

[0002] The storage and processing of umbilical cord tissue samples are of great significance in the biomedical field, especially for subsequent analysis and research. However, this technology also needs to overcome a series of technical challenges. Umbilical cord tissue is rich in stem cells and other important biological components, and the preservation quality directly affects the accuracy and reliability of the analysis results. When umbilical cord tissue is taken out during the neonatal birth process, operations must be carried out in a highly sterile environment to prevent any form of contamination, which requires very high technical and operational requirements. In addition, after the umbilical cord tissue is stored, for further analysis and research, it often needs to be contacted with specific chemical reagents or bioactive substances. This operation often requires taking the umbilical cord tissue out of the storage device again, and this operation often brings secondary contamination of the umbilical cord tissue. Therefore, how to selectively contact umbilical cord tissue with specific chemical reagents or bioactive substances without causing secondary contamination after the umbilical cord tissue sampling is closed is a technical problem existing in the prior art.

[0003] The utility model provides a storage box for umbilical cord tissues. The storage box includes a cylindrical main body, the main body includes a side wall and a bottom and has an opening at the top. The main body is divided into an upper chamber and a lower chamber, and the upper chamber and the lower chamber are separated by a rupturable membrane, and the membrane is connected to the inner side of the main body to ensure the closure of the lower chamber; the storage box also has a collar located inside the main body, the collar can pierce the membrane and displace between the upper chamber and the lower chamber, and the upper edge of the collar is provided with a flat first engaging portion and a concave second engaging portion; the storage box also has a lid, and the lower inner side of the lid is provided with a protrusion that can be engaged with the second engaging portion and can contact the first engaging portion.

[0004] Further, the lower edge of the collar is arranged in a serrated shape that is easy to cut the membrane; a second limiting portion is also provided on the inner side wall of the main body to limit the maximum displacement of the collar in the main body. An elastic buckling portion is also provided on the lid, and the elastic buckling portion is used to reversibly buckle stably with a first limiting portion provided on the outer side wall of the main body.

[0005] With the storage box for umbilical cord tissue of the present utility model, during the actual operation process, it can ensure that when the umbilical cord tissue sample is loaded into the storage box, the substances in the storage box are prevented from leaking and contacting the umbilical cord tissue. After the umbilical cord tissue sample is enclosed in the storage box, through simple operations, it can be selectively brought into contact with the pretreatment substances, avoiding the contamination problem of the umbilical cord tissue before detection and analysis, and ensuring that the pretreatment substances will not leak into the external environment. The present utility model simplifies the storage process before the monitoring and analysis of umbilical cord tissue and improves the safety of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The following will cooperate with embodiments to elaborate in detail on the embodiments of the present utility model, so as to fully understand the implementation process of how to apply technical means to solve technical problems and achieve technical effects and implement accordingly.

[0009] The storage box of the present utility model is used for storing umbilical cord tissue and providing pretreatment before tissue analysis and operation. As shown in the attached Figure 1 figure, the storage box 1 of the present utility model includes a cylindrical main body 40. The main body 40 includes a side wall and a bottom and has an opening at the top. The main body 40 is divided into an upper chamber 42 and a lower chamber 41. Chemical reagents or active substances for pretreating umbilical cord tissue are stored in the lower chamber 41. The upper chamber 42 and the lower chamber 41 are separated by a selectively rupturable membrane 30. The intact membrane 30 is connected to the inner side of the main body 40 to ensure the closure of the lower chamber 41. The membrane 30 can be selectively made of a waterproof material, preferably metal or plastic. The membrane 30 can support the weight of at least one umbilical cord tissue sample located above it. The storage box 1 further includes a collar 20 located inside the main body 40. The initial first position of the collar 20 is in the upper chamber 42 and is arranged to be slidably displaced between the positions of the upper chamber 42 and the lower chamber 41. Its first position is above the membrane 30, and the second position at the end of the displacement is at least partially penetrating the membrane 30 and displacing into the lower chamber 41.

[0010] The lower edge 24 of the collar 20 is shaped to easily cut the membrane 30, such as serrated. The upper edge 22 of the collar 20 is provided with two parts with different functions, namely a flat first engaging part 21 and a concave second engaging part 23. The storage box 1 is further provided with a lid 10 for reversibly closing the main body 40. As shown in the attached Figure 2As shown, a protruding portion 12 that can be fitted with the second engaging portion 23 and can contact the first engaging portion 21 is provided on the lower side inside the lid 10. An elastic fastening portion 13 is further provided on the lid 10 for reversibly fastening with the first limiting portion 44 provided on the outer side wall of the main body 40 stably. A second limiting portion 43 is further provided on the inner side wall of the main body 40 for limiting the maximum second position of the displacement of the collar 20 sleeved inside the main body 40.

[0011] In the initial state of the present utility model, when the protruding portion 12 of the lid 10 is located at the position of the second engaging portion 23, the separation, closing or displacement actions of the lid 10 and the main body 40 will not change the position of the collar 20. During operation, after placing the umbilical cord sample tissue on the membrane 30 and closing the lid 10, the lid 10 can be displaced upward to a position where the protruding portion 12 is disengaged from the second engaging portion 23. At the disengaged position, a rotational displacement of the lid 10 relative to the main body 40 can be achieved, so that the protruding portion 12 is located at the contact position above the first engaging portion 21. At the contact position, the lid 10 is arranged to be able to be further pushed inward, and the first engaging portion 21 of the collar 20 is pushed by the protruding portion 12 thereon, so that the collar 20 moves from the first position to the second position. During the above movement process, the lower edge 24 of the collar 20 cuts the membrane 30, so that the umbilical cord sample tissue B on the membrane 30 falls into the lower chamber 41 to contact the corresponding chemical reagent or active substance. Through the above setting method of the present utility model, on the one hand, when the operator loads the umbilical cord tissue sample into the storage box, it is avoided to contact the pretreatment substance stored in the lower chamber of the main body, and the sterility and pollution-free of the above pretreatment substance are ensured; on the other hand, the umbilical cord tissue sample will only contact the pretreatment substance after the storage box is closed, avoiding the pollution problem of the umbilical cord tissue before detection and analysis, and ensuring that the pretreatment substance will not leak to the external environment. By this setting method, the actual operation difficulty is simplified and the operation safety is improved.
