Problems solved by technology

However, sometimes, when the collected samples cannot be analyzed and tested on site, the samples need to be kept fresh, and then brought back to the laboratory for laboratory analysis
However, the existing fresh-keeping methods are relatively simple. Usually, after the samples are collected, they are refrigerated and kept fresh. However, in the process of refrigerated fresh-keeping, although it can be guaranteed that some special components in the samples will be destroyed at low temperatures, resulting in deviations in the analysis results. , which brings troubles to scientific research, especially after collecting tissue and organ samples, the functions of tissues and organs are often affected after low-temperature storage, but if they are stored at room temperature, bacteria in the air will multiply rapidly and destroy the samples. If the samples are sterilized and stored at room temperature, although this problem can be solved, the existing sterilization instruments are too large to be portable and useable.

Embodiment 1

[0030] Such as figure 1 As shown, a portable tissue sample box includes a box body 1 with a cover, a sample rack 5 is arranged in the box body 1 with a cover, a functional cavity 2 is provided in the cover body of the box body 1 with a cover, and a functional cavity 2 is arranged on the upper surface of the functional cavity 2. The fan 3 and the ultraviolet light source group, the fan 3 is connected with a driving device, and the driving device is arranged inside the functional chamber 2 . The sample holder 5 is connected with the oscillator 4, and the oscillator 4 can generate infrasonic waves, and the frequency range of the infrasonic waves is 17-23 Hz. There is an interlayer in the box body 1 with a lid, and a number of volatilization holes are evenly distributed on the surface of the interlayer. The surface of the volatilization holes is covered with a slow-release film, and the interlayer is filled with volatile sterilizing drugs. The fan 3 keeps rotating at a uniform sp...

Embodiment 3

[0034] 3, the synthetic method of 5-diaminobenzoic acid graft polyethylene glycol monomethyl ester is as follows:

[0035] Put 3,5-diaminobenzoic acid and polyethylene glycol monomethyl ether at a molar ratio of 1.2:1 in a 100mL three-necked round-bottomed flask, add p-toluenesulfonic acid and toluene at a molar ratio of 1:0.2, and 2 The esterification reaction was carried out under protection, and when the temperature of the system reached 65°C, the temperature was kept constant for 60 minutes to make it evenly mixed. Continue to raise the temperature to 120°C for reflux reaction for 2 hours; pour the obtained hot cluster product into cold water, slowly add saturated brine to extract the aqueous solution, and conduct vacuum distillation on the obtained mixture to obtain a viscous product, and then Recrystallization was carried out in a mixed solvent of ethanol: acetonitrile 1:3 to obtain a solid product.

[0036] The synthetic reaction formula is as follows:

[0037]

Embodiment 4

[0042] The synthetic method of 4-(4-aminophenoxy group) phthalic acid is as follows:

[0043] Add p-aminophenol (1.73 g, 15.8 mmol), 4-nitrophthalonitrile (2.29 g, 13.2 mmol), K 2 CO 3 (3.65 g, 26.4 mmol) and DMSO (9 mL), N 2 After stirring for 12 h under the atmosphere, the reaction solution was poured into water to precipitate, filtered and dried. The product 3 was obtained as a gray solid.

[0044] A solution of KOH (7 g, 125 mmol) in water / ethanol (50 mL / 40 mL) was added to a round bottom flask equipped with a magnetic stirring device, N 2 Bubbled for 10 min; Compound 3 (3.3 g, 14 mmol) was added to the reactor, N 2 Stir and reflux under atmosphere for 24h. After the reaction solution is cooled to room temperature, slowly add 10% dilute hydrochloric acid dropwise to the reaction solution; when the pH of the solution is 6-7, a large amount of precipitates precipitate out, filter, wash with tetrahydrofuran, and dry. The product 4 was obtained as a gray solid.

Abstract

The invention discloses a portable tissue sample box, and belongs to the field of experimental apparatuses. The portable tissue sample box comprises a box body with a cover, wherein a sample frame is arranged in the box body with the cover; a functional cavity is formed in a cover body of the box body with the cover; a fan and an ultraviolet light source group are arranged on the upper surface of the functional cavity; the fan is connected with a driving device; and the driving device is arranged in the functional cavity. According to the portable tissue sample box, sample storage and sterilization functions are integrated into one box body, so that the portable tissue sample box is convenient to carry; a biological sample, particularly tissue and organ samples, can be sterilized immediately after being collected and then stored at normal temperature; and therefore, substance components in the samples cannot be destroyed.

Description

technical field [0001] The invention relates to a sterilization box, in particular to a portable tissue sample box. Background technique [0002] In the field of biomedicine, it is necessary to collect a large number of biological samples, and then analyze and test the biological samples to obtain scientific research results. But sometimes, when the collected samples cannot be analyzed and tested on site, the samples need to be kept fresh, and then brought back to the laboratory for laboratory analysis. However, the existing fresh-keeping methods are relatively simple. Usually, after the samples are collected, they are refrigerated and kept fresh. However, in the process of refrigerated fresh-keeping, although it can be guaranteed that some special components in the samples will be destroyed at low temperatures, resulting in deviations in the analysis results. , which brings troubles to scientific research, especially after collecting tissue and organ samples, the functions...
