Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid immersion type freezing device which freezes and cools an object to be cooled such as blood contained in an amorphous container by immersing it in a cooling liquid contained in a liquid tank.

[0002]

[Prior art]

 Regarding this type of liquid immersion type freezing device, there is an application by Japanese Patent Application No. 3-32590 filed by the same applicant as the present application. FIG. 2 is a sectional view of the liquid immersion type freezing device.

The immersion type freezing device shown in FIG. 2 has a heat-insulating liquid tank 1 having an open top surface, a heat-insulating lid 2 which covers the opening of the liquid tank 1 in an openable and closable manner. Inside the liquid tank 1, the cylindrical storage frame 3 is arranged at a distance from the inner wall, the heat exchange pipe 4 is wound around the inner wall of the liquid tank 1, and the motor 5a and the stirring shaft 5b are arranged. It is composed of a stirrer 5 arranged on one side and a machine room 6 provided under the liquid tank 1. A plurality of article holding devices 7 are provided in the storage frame 3 in order to quickly freeze the object to be cooled and to easily take it in and out.

A cooling liquid F such as ethylene glycol is stored in the liquid tank 1, and a heat exchange pipe 4, a compressor 8 and a condenser 9 that form a cooling circuit are installed in the machine room 6. There is.

As shown in FIG. 3, the article holding device 7 has a pair of fixed plates 7 a and 7 b which are arranged to face each other in the storage frame 3 with a space therebetween, and a lower end portion of the fixed plate 7 a is rotatable. A flexible movable plate 7c supported by a shaft, a flexible accommodation bag 7d fixed to the mutually opposing surfaces of the fixed plate 7a and the movable plate 7c, and the movable plate 7c on the fixed plate 7a side. It is composed of a biasing compression coil spring 7e. The fixed plates 7a and 7b and the movable plate 7c are made of a material having good thermal conductivity such as aluminum, and the accommodation bag 7d is made of a cold-resistant material.

When cooling is performed by the above liquid immersion type freezing device, the cooling circuit and the stirrer 5 are operated, and the cooling liquid F is cooled by the heat exchange pipe 4 while being stirred by the stirring shaft 5 b, and the cooling liquid is cooled. When F is sufficiently cooled, an article to be cooled, for example, blood (not shown) in a sealed bag is stored in the accommodation bag 7d of each article holding device 7 and cooled to freeze it.

[0007]

[Problems to be solved by the device]

 However, the above-mentioned liquid immersion type freezing device has a problem in that the article holding device is provided in the liquid tank and occupies a large space, so that the object to be cooled cannot be stored in the liquid tank so much.

An object of the present invention is to provide a liquid tank in which a region for storing articles in the process of freezing and a region for storing frozen articles are provided, so that a limited space can be effectively used. To provide a mold freezing device.

[0009]

[Means for Solving the Problems]

 According to the present invention, in order to solve the above problems, a cooling liquid contained in a liquid tank is cooled by a cooling device, and an object to be cooled contained in an irregular container is immersed in the cooling liquid to be frozen. The immersion type freezing device is provided with a frozen product storage box for storing a frozen object to be cooled, the immersion area for freezing the object to be cooled in which the object to be cooled is frozen, and the frozen product. A frozen product storage box mounting area for mounting the storage box was provided in the liquid tank.

[0010]

[Action]

 According to the present invention, when the object to be cooled contained in the container is dipped in the cooling liquid in the immersion area for freezing the object to be cooled, the object to be cooled is frozen. When the frozen product is stored in the frozen product storage box and placed in the frozen product storage box mounting area, the frozen state is maintained.

【Example】

 FIG. 1 is a sectional view of a liquid immersion type freezing apparatus showing an embodiment of the present invention. In the figure, the same parts as those in FIG. 2 are designated by the same reference numerals, and different parts will be described below.

Reference numeral 3A denotes a storage frame, which is formed smaller than the storage frame 3 in FIG. 2 and is installed with one side in the liquid tank 1 opened, and the object to be cooled is immersed in the cooling liquid F to be frozen. It forms the immersion area for freezing the objects to be cooled. The storage frame 3A has a plurality of article holding devices 7 similar to those shown in FIG. Reference numeral 10 denotes a frozen product storage box for storing a frozen object to be cooled, which is a storage box mounting frame 11 having a water immersion prevention structure provided adjacent to the immersion area for freezing the object to be cooled in the liquid tank 1. It is placed inside. The installation space of the storage box mounting frame 11 forms a frozen product storage box mounting area on which the frozen product storage box is mounted. FIG. 4 is a perspective view of the frozen product storage box 10. The frozen product storage box 10 includes a box body 12 to which a lid 13 that can be opened and closed is attached, and both sides of the box body 12 are provided with carrying handles 14 that can be stored and withdrawn.

In the above configuration, when freezing an object to be cooled such as blood, the cooling liquid F is cooled to a predetermined temperature in advance, and the object to be cooled in a sealed bag is housed in the article holding device 7 and cooled. Immerse in liquid F. The frozen product storage box 10 is placed in the storage box mounting frame 11 in advance or at a proper time, and when the object to be cooled is frozen, the frozen product is replaced with the frozen product storage box 10. After that, the frozen product in the frozen product is maintained in the frozen state. In the frozen product storage box 10, frozen products are stored in close contact with each other, and the storage amount per unit space is extremely large compared to the case where the frozen products are stored in the storage device 7. The total capacity increases. The frozen product stored in the frozen product storage box 10 is taken out of the liquid tank 1 as it is as needed, and transported to the outside. When this liquid immersion type freezing device is applied to a blood collection vehicle or the like, the blood can be sequentially frozen according to the progress of blood collection, and can be sequentially transferred to cold storage. It is possible to effectively use the space provided.

[0014]

[Effect of device]

 As described above, according to the present invention, an immersion area for freezing an object to be cooled in which an object to be cooled contained in an irregular container is frozen by immersing it in a cooling liquid, and a frozen product containing the frozen product. Since the frozen product storage box mounting area for cooling the storage box is provided in the liquid tank, the frozen product frozen in the immersion area for freezing the object to be cooled is stored in the frozen product storage box and placed in the frozen product storage box. Cooling in the area makes it possible to effectively use the limited space in the liquid tank.
