Description

Detailed Description of the Invention: Industrial Field 1: The invention is for use in artificial fertilization, in which preserved spermatozoa are thawed and kept at a temperature suitable for fertilization during artificial insemination in the breeding industry. This relates to crystal devices.

Structure of the conventional example and its problems In recent years, artificial insemination using preserved sperm has been carried out in the decomposition industry. A method has been adopted in which frozen sperm is inserted into the container.

In this method, the following methods were used to obtain a nutrient solution at a constant temperature and constant volume. That is,
Put the specified nutrient solution into a glass beaker, place the beaker in an insulated container, gradually pour hot water into the container, and raise the temperature inside the beaker with a hot water bath.
A thermometer placed in the beaker is used to visually confirm that the specified temperature has been reached.

However, with the above method, there are unstable factors such as visual temperature confirmation or pouring hot water, and the nutrient solution has to wait until it reaches a predetermined temperature, which is a cumbersome process. It's something.

Purpose of the Invention In view of the above-mentioned drawbacks of the conventional technology, the present invention provides a method for automatically supplying a nutrient solution at a predetermined temperature to thaw frozen sperm, raise the temperature using the Fertility System, and keep it warm during artificial insemination. The present invention provides a device for supplying.

The operation of the 11° C. I temperature device for artificial fertilization of this embodiment configured as described above will be described below.

First, a nutrient solution is poured into the small container 15 and placed at the bottom of the inner container 2 using the holder 13. Next, the outer lid 5 is closed, the product is transferred to the constant temperature device for artificial fertilization, and the switch 46 is turned on.

Then, the ON lamp 19 lights up and the motor timer 44 starts counting the set time T.

Then, by valving the resistor 25° rectifier diode 26, the current condenser 27 is charged and the direct current of the self-control device j1σ12 is generated.

In the density control device 12, the output of the voltage comparator 31 is at a high level when the Ti melt in the internal cooling chamber 2 is low and the resistance of the negative characteristic thermistor is affected, that is, immediately after energization. As mentioned above, the short transistors 32 and 34 are resistors 3
Since it is connected to 1rj-connection terminal 21 through resistors 33 and 35, only IJ and '1', through which the base current flows through these resistors 33 and 36, are turned on. Therefore, transistor 3
4 is turned off only near the zero point of the power supply voltage and is normally turned on. Therefore, the connection point P is at a low temperature and reaches a high level only near the zero point of the power supply voltage, turning on the transistor 42, so that the bidirectional three-terminal cyrisk 23 conducts and energizes the electric heating elements 7 and 8.

In this way, the electric heating elements 7 and 8 are energized and the inner container 2 is heated. The upper opening of the inner container 2 is closed by the inner lid 6 to form a closed space 9, and the heat added by the electric heating elements T and 8 is effectively transferred into this closed space by the action of the heat insulating material 3.4. Raise the temperature by 2'.

Next, when the f11j control temperature 5 reaches the temperature determined by the resistance values of the resistors 28 and 29.30 and the temperature characteristics of the negative characteristic thermistor, the output of the voltage comparator 31 becomes a low level, so the connection point P becomes a low level. L・Ran resistor 42
is not turned on. Therefore, both directions・]1. The three-terminal scissor 23 is no longer conductive, and the electric heating elements 7 and 8 are not energized and do not generate heat.

In this way, the temperature of the inner container 2 is detected by the temperature detection device 9 consisting of a negative characteristic thermistor.
2 keeps the temperature inside the inner container 2 constant. After the nutrient solution 16 contained in the inner container 2 rises to a predetermined temperature, it is maintained at that temperature. Here, the setting time T of the motor timer 44 mentioned above is set to, for example, 10 to 15 minutes so that the nutrient solution 16 is controlled to a predetermined width and stabilized, and after this time T has elapsed, the switch 48 is turned on and the ceramic piezoelectric buzzer is activated. 5Q rings. When the notification device 47 gives the notification at [C-], the nutrient solution 16 is stably maintained at a predetermined throat temperature.

As described above, it is possible to obtain the nutrient solution 16 at a constant temperature necessary for thawing frozen sperm, and then the notification device 47
The user is notified by this, and all that is left to do is to put the sperm stored in this nutrient fluid into the nutrient solution to restore the sperm to a fertile state.

As described above, each small container 15 is made of VC glass, so it is hygienic and is not easily scratched, and is held separately by the size holder 13, so it is hard to break.

The set time T of the motor timer 44 may be set externally depending on the user or the amount of frozen sperm, and the timer 46 may be an electronic timer using a delay circuit. It may be.

The pond water invention is not limited to the above embodiments,
It is subject to change and implementation as appropriate within that scope.
