Detailed Description

The present invention will be described in detail with reference to the accompanying fig. 1, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a novel 12L portable biological sample sampling tank through improvement, as shown in figure 1, which can be implemented as follows; comprises a bucket lifting hook 1, a retainer 2, a lifting handle 3, a heat insulation plug 4, a vacuum sealing opening 5, a neck tube 6, a vacuum layer 7, a multilayer winding 8, an adsorbent 9, an inner container 10, a shell 11, a side support 12, a lifting bucket 13, a bottom support 14 and a shell bottom 15. The utility model discloses a welding process, special roll and glue technology, manage to find time technology etc. and connect into a bore 80 mm's vacuum intermediate layer jar body, inner bag 10 covers multilayer composite insulation material to be furnished with insulating plug 4 and carry a section of thick bamboo 13. An epoxy glass fiber reinforced plastic support and an aluminum alloy side support 12 are additionally arranged on the side wall between the inner container 10 and the shell 11; the heat insulation plug 4 is made of polyurethane foam with good heat insulation performance, and a groove is formed in the plug body; the widened design of the bottom 15 of the shell increases the stability of vehicle-mounted transportation, and the bottom support 14 and the shell exert efficient anti-seismic performance; the lifting sleeve 13 is provided with a cover.

The utility model discloses can only fill the dress liquid nitrogen, other low temperature medium can not pack into, especially can not be used for filling dress liquid oxygen to the flammable substance emergence effect in with container self structure arouses the explosion. The container has good anti-seismic performance and portability, and can be placed into a trunk of a household bridge car to meet the requirements of collection, storage and transportation of biological samples.

The first technical parameter is as follows: effective volume: 12.5L; caliber: 80 mm; outer diameter: 455 mm; height: 394 mm; empty weight: 8.2 Kg; static liquid nitrogen retention period: the time is more than or equal to 41 d.

Secondly, the use method comprises the following steps:

1. filling liquid nitrogen: when liquid nitrogen is filled for the first time and refilled after long-term use, because the inner container is at normal temperature, the filling is not too fast, a small amount of liquid needs to be injected firstly, the inner container is cooled gradually, and the filling speed is increased after the liquid nitrogen boils slowly, otherwise the liquid nitrogen can boil and splash outwards, thereby causing frostbite. The liquid nitrogen should not be filled too full, and the liquid level should not be high enough to contact the glass fiber reinforced plastic neck tube. Instead of flushing the neck with liquid nitrogen, the filling tip should be inserted into the bottom of the container and refilled with liquid nitrogen.

2. Picking and placing refrigerated articles: when taking and placing the sample, firstly, the cover plug is vertically and lightly taken off, then the lifting cylinder is vertically lifted and lightly moved to the middle of the container, the cover of the lifting cylinder is opened, and the sample is taken and placed. It is preferable to take and place the object in the neck tube of the container (if the lifting cylinder must be lifted out of the container and then the object is taken and placed, after the liquid nitrogen higher than the side hole of the lifting cylinder is discharged, the lifting cylinder is lifted out of the container, so that the liquid nitrogen is prevented from escaping from the side hole and hurting people). After the container is taken and placed, the cover is closed immediately to slightly reset the lifting cylinder and the cover plug, attention is paid to shortening the opening time of the bottle mouth as much as possible, and the lifting cylinder cannot be completely taken out at the same time so as to prevent the container from absorbing moisture in the air, increase the evaporation loss of liquid nitrogen and influence on the storage effect of frozen articles. When the barrel is passed through the neck, care is taken not to hit the neck, so as not to damage the container.

3. Liquid level height inspection: the lowest liquid level energy of the liquid nitrogen is lower than the highest surface of the refrigerated object so as to ensure that the refrigerated object is submerged by the liquid nitrogen. When the liquid nitrogen is evaporated to the extent that the refrigerated object is exposed to the liquid surface, the liquid nitrogen is supplemented in time. The container can judge the liquid nitrogen height by eyes after the cover plug is opened according to the optimized overall dimension and caliber, and other measuring tools are not needed.

4. And (3) evaporation loss determination: the weight method and the flow method are used for measurement.

The flow method is measured by a gas flowmeter, and the operation method is described in the specification of the flowmeter.

The weighing method uses a platform scale for weighing, and uses the platform scale which passes the test in 50K so as to avoid inaccurate weighing.

And (3) after the container which is not precooled is filled with liquid nitrogen, placing for 24-48 hours, fully cooling the container, and then measuring the sun evaporation loss. Weighing the container firstly, weighing once again after 24 hours, wherein the difference of the two weights is the daily steaming loss of the container, and continuously measuring for three days. The average daily steaming loss of the container is calculated firstly, and then the daily steaming loss rate and the liquid nitrogen retention period are calculated.

Use notes:

1) the ice floating on the liquid surface can be taken out at any time, and the cold block attached to the neck pipe is not peeled off by hard objects so as to avoid damaging the neck pipe.

2) It is critical to prevent corrosive drugs and other foreign matter from falling into the container to prevent damage and contamination to the container.

3) The vacuum suction nozzle adopts a structure capable of repeatedly sucking air, and a user does not need to start the vacuum suction nozzle, so that the cold insulation performance is not influenced.

4) The liquid nitrogen temperature is-196 deg.C, and the operation should be protected, such as wearing leather and cotton gloves, so that the hands are not exposed. The liquid nitrogen is prevented from splashing and touching the skin or eyes to cause frostbite.

5) Only can use a matched bottle stopper and can not be replaced by other unqualified articles. Otherwise, the container performance is affected, and even the container is damaged due to the formation of compressed air pressure caused by the continuous evaporation of the liquid nitrogen.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
