Description
Technical field
The utility model is related to field of medical device, more particularly to the sample storage facilities of a kind of automatic liquid supply.
Background technology
The nitrogen of liquid is colourless, odorless, non-corrosive, temperature is extremely low.Nitrogen constitutes the major part (volume ratio of air
78.03%, weight ratio 75.5%).Nitrogen is inactive, does not support to burn, and liquid nitrogen is commonly used to preserve living tissue, biological sample
And sperm and ovum.
Medical sample storage facilities generally comprises storage bin and supply tan.During scientific experiment, due to testing demand,
Cord blood is carried out sometimes for sample to be put into storage bin, but in use, needs manually to carry out using supply tan
Fluid infusion, this operating method complex steps, can not know the content of liquid nitrogen in storage bin during fluid infusion, be easy because of fluid infusion not
It causes sample in non-cryogenic ambient storage in time, sample activity is made to reduce, subsequent experimental can not be carried out；Again very due to supply tan
Weight, the time for replacing supply tan needs is longer, can not continue to be filled with liquid nitrogen into storage bin during replacement, to influence sample
Activity.
Utility model content
The utility model is intended to provide a kind of sample storage facilities of automatic liquid supply, to solve existing sample storage device
It is easy to cause the problem of sample activity reduces in use.
A kind of sample storage facilities of automatic liquid supply in this programme, including storage bin and two positioned at storage bin both sides
Device for supplying, the device for supplying include supply tan, and supply tan is communicated with output channel, and output channel is equipped with water pump, described
Storage bin be equipped with liquid crystal touch screen, magnetostriction liquidometer and receiving pipeline, the one end of receiving pipeline far from storage bin with it is defeated
Go out pipeline to be detachably connected, receiving pipeline is equipped with solenoid valve, and the magnetostriction liquidometer passes through electric signal and LCD touch
Shield two-way communication, alarm module is equipped in the liquid crystal touch screen, the data that liquid crystal touch screen sends out flexible liquid level gauge are sent
To alarm module, alarm module is used to after receiving the liquid level information that magnetostriction liquidometer is fed back be warned according to information
Report.
Operation principle in this programme：In use, the article stored will be needed to be put into storage bin, then by supply tan and store up
It deposits case to be connected to output channel by receiving pipeline, opens the solenoid valve of one of device for supplying, by the liquid in the supply tan
Nitrogen is added to by output channel and receiving pipeline in storage bin, and magnetostriction liquidometer can be to the liquid nitrogen liquid in storage bin at this time
Position is monitored, and will send information to LCD touch screen display, when the liquid nitrogen deficiency in the device for supplying, alarm module
The information in liquid crystal display is received, alarm is started, closes the solenoid valve of the device for supplying at this time, replaces device for supplying, this
Another device for supplying of Shi Kaiqi makes it continue to supplement liquid nitrogen to supply tan.
Advantageous effect in this programme：Storage bin in the device is connected with magnetostriction liquidometer, magnetostrictive liquid level
Meter will send information on liquid crystal touch screen, the sustainable liquid level measured in storage bin of magnetostriction liquidometer, measurement accuracy pole
The secondary meter of height, magnetostriction liquidometer uses standard output signals, is handled signal convenient for microcomputer, easy to implement
Net work, improves the degree of automation of entire measuring system, may know that the content of liquid nitrogen in storage bin at any time, can be stretched by mangneto
The information of contracting liquid level gauge output replaces device for supplying in time；After the liquid nitrogen in a device for supplying is finished, another benefit is opened
Can not be able to be that storage bin persistently supplements liquid nitrogen when replacing liquid supply device to device, such setting can effectively avoid sample storage
Cryopreservation device is the problem of the process used is easily reduced sample activity.
Further, it also is provided with magnetostriction liquidometer in the supply tan, the magnetostriction liquidometer in supply tan
By electric signal and liquid crystal touch screen two-way communication, the magnetostriction liquidometer in supply tan sends data to alarm module, report
Alarm is carried out according to information after liquid level information of the alert module for receiving the feedback of the magnetostriction liquidometer in supply tan.
It is also provided with magnetostriction liquidometer in supply tan, sends out alarm when liquid nitrogen off-capacity inside storage bin, such setting can be right
Storage device checked, if liquid nitrogen is sufficient in supply tan, and liquid nitrogen level reduces in storage bin, so that it may judge supply tan with
Connection between storage bin goes wrong.
Further, the receiving pipeline is equipped with safety valve.It is only needed the liquid nitrogen content control in storage bin during use
System is 90%~95%, and safety valve automatically turns on when liquid nitrogen content is less than 90% in storage bin, when liquid nitrogen content is higher than 95%
Safety valve is automatically closed, and such setting can avoid the waste of liquid nitrogen.
Further, lifting platform is equipped in the storage bin.When placing sample, lifting platform only need to be risen, sample is put into liter
It drops on platform, then declines lifting platform, so there is no need to use clip to clamp sample to place into storage bin.
Further, the storage bin and supply pot bottom are equipped with transport wheel.If you need to shift sample storage device when use,
Transport wheel can be used directly, the device is entirely moved to other positions.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the sample storage facilities of automatic liquid supply of the utility model；
Fig. 2 is a kind of signal transmission schematic diagram of the sample storage facilities of automatic liquid supply of the utility model.
