Description

Technical Field

[0001] This utility model relates to the field of preservation fluid bottles, specifically a preservation fluid bottle for pancreatic islet cells. Background Technology

[0002] Preservation of pancreatic islet cells is of great significance for medical research such as diabetes treatment and islet transplantation. However, islet cells have extremely high requirements for the preservation environment, and it is necessary to ensure that they are not contaminated and maintain their viability during the preservation process. Traditional preservation solution bottles often only focus on the airtightness and the capacity of the preservation solution, while neglecting other requirements for pancreatic islet cell preservation, such as light protection and shock resistance.

[0003] Traditional preservation solution bottles typically consist of a bottle body and a cap, with the cap connected to the bottle body via threads for a seal. However, this design has some limitations in pancreatic islet cell preservation:

[0004] Insufficient sealing: While traditional threaded connections can achieve basic sealing, vibration or temperature changes during long-term storage or transportation may cause the threads to loosen, affecting the sealing effect. Lack of light protection: Pancreatic islet cells are sensitive to light; prolonged exposure to sunlight may lead to decreased cell activity. Traditional preservation solution bottles typically do not provide light protection.

[0005] Insufficient protection: During transportation or storage, the preservation solution bottle may be bumped or impacted, causing the bottle to break and thus affecting the preservation effect of pancreatic islet cells. Utility Model Content

[0006] The purpose of this invention is to provide a preservation solution bottle for pancreatic islet cells to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bottle for preserving pancreatic islet cells, comprising a bottle body, a bottle cap screwed to the top of the bottle body, a stopper integrally formed on the surface of the bottle cap, a rubber cover fixed inside the stopper, an elastic band fixed to one end of the rubber cover, and the rubber cover folded outward and fitted onto the outside of the bottle body, with the elastic band positioned below the bottle body.

[0008] Preferably, the bottle cap is an annular plate with an "L"-shaped cross-section, and the inner annular surface of the bottle cap is provided with internal threads.

[0009] The top outer ring of the bottle is provided with external threads, which are connected to the internal threads.

[0010] Preferably, the plug has a circular frame structure, and a baffle is fixed to the inner ring surface of the plug. The baffle is a circular plate, and the rubber cover is inserted between the plug and the baffle for storage when not in use.

[0011] Preferably, a limiting ring is fixed on the top surface of the baffle. The limiting ring is an inverted "convex" shaped circular plate, and the inner diameter of the limiting ring is equal to the inner diameter of the baffle.

[0012] Preferably, the diameter of the elastic band loop in its initial state is equal to the inner diameter of the limiting ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The preservation solution bottle for pancreatic islet cells proposed in this invention features a rubber cover that can be stored between the stopper and baffle when not in use, or folded outwards to cover the outside of the bottle, providing light protection to the islet cells from light damage. The folded-out rubber cover also increases the bottle's impact resistance, preventing breakage during transportation or storage. The elastic band design ensures the rubber cover is securely attached to the bottle, preventing it from easily falling off, while allowing the user to easily remove or add the cover as needed.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a bottle for preserving pancreatic islet cells, comprising a bottle body 1, a cap 2 screwed to the top of the bottle body 1, the cap 2 being an L-shaped annular plate, the inner annular surface of the cap 2 having an internal thread, and the outer annular surface of the top of the bottle body 1 having an external thread, the external thread and the internal thread engaging; a stopper 3 integrally formed on the surface of the cap 2, a rubber cover 6 fixed inside the stopper 3, the stopper 3 having a circular frame structure, and a baffle 4 fixed to the inner annular surface of the stopper 3, the baffle 4 being an annular plate, the rubber cover 6 being inserted between the stopper 3 and the baffle 4 for storage when not in use; the bottle body 1 is screwed to the top of the bottle body 1, the cap 2 being an L-shaped annular plate, the inner annular surface of the cap 2 having an internal thread, and the inner annular surface of the stopper 3 having a baffle 4 fixed thereon, the rubber cover 6 being inserted between the stopper 3 and the baffle 4 for storage; the bottle body 1 is screwed to the top of the bottle body 1, the cap 2 being an L-shaped annular plate, the inner annular surface of the stopper 3 having a baffle 4 fixed thereon ... After the liquid is injected into the bottle body 1, the bottle cap 2 is screwed onto the top of the bottle body 1 to seal the bottle mouth of the bottle body 1. The stopper 3 is inserted into the bottle mouth of the bottle body 1. The bottom end of the sealing ring 8 is fitted with a sealing ring 8, which is clamped between the stopper 3 and the bottle body 1 to improve the sealing performance after the bottle cap 2 and the bottle body 1 are connected. One end of the rubber cover 6 is fixed with an elastic band 7. When the rubber cover 6 is not in use, the rubber cover 6 is inserted under the baffle 4 and the elastic band 7 is fitted onto the limiting ring 5. In this way, the bottle cap 2 and the stopper 3 not only seal the bottle mouth of the bottle body 1, but also store the rubber cover 6.

[0024] After the rubber cover 6 is folded outward and fitted onto the outside of the bottle body 1, the elastic band 7 is located below the bottle body 1. The top surface of the baffle 4 is fixed with a limiting ring 5, which is an inverted "convex" shaped circular plate. The inner diameter of the limiting ring 5 is equal to the inner diameter of the baffle 4. The diameter of the elastic band 7 in its initial state is equal to the inner diameter of the limiting ring 5. After the rubber cover 6 is pulled out from the baffle 4, it is folded outward and fitted onto the outside of the bottle body 1. The rubber cover 6 not only serves to block light from the bottle body 1, but also protects the bottle body 1 from damage caused by impact.

[0025] The detailed procedure for the preservation solution bottle used for pancreatic islet cells is as follows:

[0026] Measure an appropriate amount of islet cell preservation solution, ensuring the liquid is clean and uncontaminated. Rotate the cap 2 counterclockwise to remove it from the screw connection at the top of the bottle body 1. Carefully pour the preservation solution into the bottle body 1, avoiding spillage or contamination of the bottle opening. Ensure that the components, including the stopper 3, baffle 4, rubber cover 6, elastic band 7, and sealing ring 8, are complete and in good working order. Place the sealing ring 8 onto the bottom of the stopper 3, ensuring it fits tightly against the bottle opening of the bottle body 1. Insert the stopper 3 into the bottle opening of the bottle body 1, ensuring it is aligned. Align the internal thread of the cap 2 with the external thread of the bottle body 1, and rotate the cap 2 clockwise until it is securely screwed in. Ensure the connection between the cap 2 and the bottle body 1 is firm and not loose. Insert the folded rubber cover 6 into the gap between the baffle 4 and the stopper 3. Pass the elastic band 7 through one end of the rubber cover 6 and place it on the retaining ring 5. Ensure the elastic band 7 fits tightly against the retaining ring 5 to prevent the rubber cover 6 from falling off. When it is necessary to take the preservation fluid bottle out of the laboratory or for light protection, remove the elastic band 7 from the retaining ring 5. Fully pull the rubber cover 6 out from under the baffle 4 and fold it outwards to fit over the outside of the bottle body 1. Ensure the rubber cover 6 completely covers the bottle body 1 without any gaps. The elastic band 7 should be positioned below the bottle body 1 and should not affect the light-blocking effect of the rubber cover 6.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
