Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a cell culture transporter, and more particularly to a transporter capable of transporting a fertilized egg or an immature egg in a living state or keeping a constant temperature in a place without a power source for a long time.

[0002]

[Prior Art]

 With the spread of in-vitro fertilization technology for livestock, it is important to transport fertilized eggs or ova in follicles.For transporting them, water bottles or incubators containing warm water, or power sources such as a centr or a cigar The temperature of the water in the thermostatic chamber was mainly controlled by taking it from a lighter and adjusting the heater with it.

[0003]

[Problems to be solved by the device]

 The incubator described above puts fertilized eggs, cells, etc. in a test tube, etc., and puts the test tube vertically in a constant temperature tank for transportation, so the test tube may fall over due to vibration during transportation, etc. There are problems that the fertilized eggs and cells in the tube are damaged and the whereabouts are unknown. There is also a heater that heats the heater with a power source obtained from an automobile cigarette lighter to keep the temperature at a constant temperature. However, since the cigarette lighter needs a power source, a third party such as a courier service I have a problem that I can not consign the transportation to.

Further, the water bottle type incubator has a problem that when the lid is removed, the entire test tube comes into contact with the outside air, the temperature greatly changes, and it is difficult to control a constant temperature.

The present invention has been made in view of the problems of the above-described conventional techniques, and its purpose is to avoid the influence of vibration during transportation and to prevent the amount of contact with the outside air when the lid is opened. The objective is to provide a cell culture transporter that can be outsourced to courier companies with a minimum of temperature fluctuations to minimize temperature changes.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the cell culture transporter of the present invention is equipped with a heater for holding and holding a battery and a test tube (straw) in a horizontal state in a case body having an adiabatic heat retention function. In addition to having a built-in container, the openable and closable lid of the test tube holding container is divided into large and small parts that can be opened and closed independently, and is equipped with a temperature adjustment mechanism that adjusts the temperature inside the case body. To do.

The case body described above is formed by molding a synthetic resin material and is filled with a heat insulating material such as styrene foam between the inner and outer cases. In such a case body, a hermetically sealed battery is made of styrene foam or the like. It is accommodated via a holding material. The test tube holding container is a container in which a large number of substantially U-shaped grooves into which a test tube (straw) can be fitted horizontally are formed on the surface of a metal flat plate having a sheet heater built therein, and its container. The lid consists of a lid that can be opened and closed, and a lid that covers the range of the product number display on one surface of the straw and a large lid that covers the rest of the straw. It is divided in two.

[0008]

[Action]

 According to the above means, the heater of the test tube holding container is heated by the battery, and the heating temperature is held at the temperature set by the temperature adjusting mechanism. Since the straw containing the fertilized eggs and cells held in the test tube holding container is horizontal, it is less affected by vibration during transportation, and the product number display section displayed on the straw is not affected. Can be confirmed by opening the small lid that covers this portion, and the portion containing the fertilized eggs etc. is covered with the large lid so that it is not exposed to the outside air.

[0009]

[Effect of the device]

 Since the cell culture transporter of the present invention is configured as described above, the test tube (straw) containing the fertilized egg or cells can be held in a horizontal state, and the fertilized egg or the like is damaged by vibration during transportation. It can be surely prevented. Moreover, the lid of the test tube holding container that accommodates the test tube (straw) is divided into a large lid and a small lid, and the small lid covers the range of the part number display section of the test tube. When checking the part number of the test tube, only the small lid required for checking needs to be opened, so temperature changes due to contact with the outside air can be minimized, thereby maintaining the set temperature in a stable manner. I can. Furthermore, since the battery is built-in as a heat source for heating the heater, the transportation can be safely outsourced to a third party such as a courier.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a case body, which is formed by inserting a foam material exhibiting a heat insulating and heat retaining function between an inner member and an outer member molded of a synthetic resin material. It is composed of a lid 1b, and the lid 1b is attached by a hinge so that it can be opened and closed.

A holding material 2 made of styrofoam is fitted inside the case body 1 described above, and a recess 3 is formed in the holding material 2 so that a hermetically sealed battery 4 is fitted and fixed. A charging terminal 17 for the battery 4 is provided so as to project on the side surface of the case body 1. A test tube holding container 5 and a temperature adjusting mechanism 6 are horizontally arranged above the holding material 2.

The test tube holding container 5 is made of a metal plate having good thermal conductivity, for example, an aluminum plate, and has a large number of U-shaped fitting grooves 8 on which the test tube (straw) 7 can be fitted. It is composed of a container 5a provided and a lid 5b covering the fitting groove 8 formed in the container 5a. The lid 5b is divided into a large lid 9 and a small lid 10 into two bodies 5a. It is attached with a hinge so that it can be opened and closed. Further, planar heaters 11 are attached to the container 5a and the lid 5b, respectively, and are heated by the battery 4.

The size of the small lid 10 in the lid 5b is a size that covers the range of the display portion such as the product number displayed on the outer surface of the test tube 7 on one side, and the The lid 5b does not have to be opened as a whole. Further, the test tube holding container 5 configured as described above is horizontally arranged on the upper part of the holding material 2 via the cushion material 12, and the periphery of the container 5 is also covered with the cushion material 12 to provide the test tube. Both side ends of the test tube 7 contained in the holding container 5 collide with the cushion material 12 to prevent the test tube 7 from moving.

The temperature adjusting mechanism 6 is composed of a substrate 13, a temperature setting section 14, a set temperature display section 15 and the like. A memory for setting temperature and a temperature detecting sensor are backed up by a battery 16 charged from a battery 4 and driven. In addition, a handle 16 for attaching and detaching the mechanism is attached on the upper surface.

Fertilized eggs and the like that are housed and transported in the cell culture transporter configured as described above are those that are filled with a culture solution in a straw, and are partitioned by providing air layers on both sides, and both ends of the straw are stoppered. Since such a straw is accommodated horizontally in the test tube holding container 5, even if there is vibration during transportation, the straw is not affected by the vibration and can be transported with peace of mind. The straw is then maintained at a constant temperature by a battery operated heater.
