AI Technical Summary
Existing articular cartilage tissue sample preservation devices lack effective cushioning and shock absorption structures during transportation, which leads to vibration affecting temperature stability and sample damage. At the same time, unreasonable layout of the thermos bottles results in uneven distribution of cold energy, reducing the insulation effect.
A portable storage device including a buffer chamber and a buffer assembly was designed. Vibration is mitigated by the support column, buffer plate and spring structure in the buffer chamber. The layout of the thermos bottle is optimized by combining the heat preservation frame and limiting groove to ensure uniform distribution of cold energy.
It effectively mitigates the impact of external vibrations on the samples, improves temperature stability and insulation, protects the sample storage bottles, and enhances the overall preservation performance of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sample preservation devices, specifically a portable articular cartilage tissue sample preservation device. Background Technology
[0002] The preservation of articular cartilage tissue samples is of great significance for medical research, clinical diagnosis, and tissue engineering. After sample collection, they must be placed in a specific environment (such as low temperature or constant temperature conditions) to maintain cell viability and tissue structural integrity. Common sample preservation devices consist of a box, lid, lock, insulated bottle, and sample storage bottle. The following drawbacks have been observed in their use:
[0003] 1. During transportation, the device is often subjected to external vibration or impact, and existing designs lack effective cushioning and shock absorption structures. Vibration may cause collisions between sample storage bottles or displacement of insulated bottles, thereby affecting temperature stability and even causing sample damage;
[0004] 2. Traditional devices typically stack insulated flasks and sample storage bottles simply inside the box without considering space optimization or uniform heat distribution. This disordered placement can lead to uneven cold distribution, localized temperature fluctuations, and reduced overall insulation performance. Furthermore, gaps between the insulated flasks and the box can increase cold loss, further impacting preservation performance.
[0005] Therefore, based on this, we have studied and improved the existing structure and proposed a portable articular cartilage tissue sample preservation device. Utility Model Content

[0028] Please see Figure 3An inner box 101 is fixedly installed inside the box body 1, and an inner cover 201 is fixedly installed inside the cover body 2. Buffer cavities are formed between the box body 1 and the inner box 101, and between the cover body 2 and the inner cover 201. Four support columns 4 are fixedly installed in the buffer cavities. The buffer cavities are divided into four parts, and a buffer assembly 5 is installed between two adjacent support columns 4 in each buffer cavity.

A rod body 505 is hinged between the corresponding connecting clips 503 and connecting clip 504. When the device is subjected to impact or vibration, the buffer plate 501 will slide in the buffer cavity, the spring 502 will deform, the connecting clamp 504 will slide on the buffer plate 501, and the rod 505 will rotate within the connecting clamp 503 and the connecting clamp 504, thereby buffering the impact or vibration received by the device.
[0029] Please see Figure 3 Several buffer components 6 are provided between the bottom of the inner box 101 and the bottom of the inner box 1, and between the top of the inner cover 201 and the top of the inner cover 2. Each buffer component 6 includes a buffer cylinder 601, which is fixedly connected to the corresponding bottom of the inner box 1 or the top of the inner cover 2.
