Description

[Detailed Description of the Invention] The present invention relates to a device for carrying articles into a breeding container for breeding experimental animals such as mice and rats in a sterile state.

As shown in Fig. 8, a conventional breeding container for this species includes a container body A made of transparent hard synthetic resin, a filter B for intake or exhaust, and an article carrying tube C1 for attaching instruments, etc. to the container body A.
Also provided are rubber gloves that allow the instruments inside the container body A to be operated from outside the container body A.

This article transport tube C! i It has an outer cap E and an inner cap F which are made of hard plastic or resin, and when the outer cap E is opened, an article such as a rearing cage is carried into the article carrying tube C, and then Close the outer camp E and sterilize the breeding cage by spraying disinfectant from the chemical spray port G. Next, use rubber gloves DK to open the inner cap F from the inside of the container body, and insert the sterilized breeding cage into the container body A. It is used so that it can be stretched inside.

On the other hand, this conventional sterile rearing container had the drawback that since the container body A was made of hard synthetic resin, it could not be folded even when not in use, and it took up a lot of space for transportation and storage.

Therefore, it has been considered to manufacture the container body A using a soft synthetic resin film, but since the soft synthetic resin film has no fixed shape and is weak in strength, the conventional filter 4, article carrying tube, and Rubber gloves etc. cannot be used as they are.

For example, the above-mentioned article carrying tube C is made of hard synthetic resin and is strong and relatively heavy, so if it is attached to a container body made of soft synthetic resin film, the container body will be weaker. As a result, an unreasonable force is applied to the container main body, which makes the container unstable in shape and easily torn, and the article carrying tube C also has an unstable posture, making it difficult to operate.

It is also difficult to attach the enclosed article carrying tube C to the container body with sufficient sealing performance, resulting in high costs.

The present invention was developed in view of the above-mentioned circumstances, and it is an object of the present invention to provide an article carrying device that is lightweight, does not apply excessive force to the container body, is foldable, is convenient for transportation and storage, and is inexpensive. The purpose is to

The present invention provides communication between the inside of the container body and the inside of the article carrying bag by thermally welding the base of an article carrying bag made of a cylindrical body made of a soft synthetic resin film to a container body made of a soft synthetic resin film, A clamping fitting for sealing the base is removably attached to the base of the bag on the bag for transporting the goods, and a medicine spray port communicating with the outside is provided at an appropriate position of the bag for transporting the goods, and a plug for closing the medicine spray port. It is characterized by having a body.

Hereinafter, one embodiment of the present invention will be described based on the drawings. A box-shaped container body 1 as shown in FIG. Intake side filter device 3 connected to blower 2
, the other end is equipped with an exhaust one-law filter device 4.

As shown in FIG. 2, the intake side filter device 3 includes a ring 5 made by cutting a paper tube into appropriate widths, and a pair of nets 6 such as insect repellent nets.
, 6, a filter sheet 7, and a cover sheet 8, the filter sheet γ is sandwiched between the pair of nets 6 and 6, and the ring 5 is fitted into the intake hole 9 of the container body 1 to intake air. The peripheral film 10 around the hole 9 is wrapped around the ring 5, and the peripheral edge of the filter sheet γ and the nets 6, 6 are wrapped around the ring 5 as shown in FIG. - The adhesive tape 11 is wound and bound so as to press against the ring 5 from above the peripheral edge of the sheet 80, and thereby the nets 6, 6 and the filter sheet 1
, a cover sheet 8 and a ring 5 are attached to the container body 1.

A blower 2 is connected to the opening 12 provided on the cover sheet 8, and the air blown into the opening 12 by the blower 2 is cleaned through the filter sheet 7 and then fed to the container body 1. There is.

On the other hand, the exhaust side filter device 4 has the same configuration as the intake side filter device 3 except that the cover sheet 8 is removed.

In addition, two left and right openings are provided near the top of the front surface of the container body 1, and the bases of sleeve sleeves 13, 13 made of soft synthetic resin film are attached to these openings by heat welding 14°14, and the sleeve sleeves are Neoprene rubber gloves 15.15 are fastened to the cuffs of the 13te 13.

A connecting ring 16 made of hard synthetic resin as shown in FIG. 6 is used to connect the sleeve sleeve 13 and the glove 15.

This connecting ring 16 has several threads (three threads in the drawing) on the outer periphery.
First, the cuff of the cuff 13 is placed over the connecting ring 16 and secured with adhesive tape, and then the base of the glove 15 is elastically placed over the connecting ring 16, and from above A rubber ring 18 is wound around the concave groove 17 so that it can be stretched.

The gloves 15 and the cuffs 13 are turned inside out and housed inside the container body 1, and the rearing experimenter can use them from the outside with his/her hands and arms to operate the articles and equipment inside the container body 1.

Now, reference numeral 19 denotes an article carrying bag made of a cylindrical body made of a soft synthetic resin film.
The inside of the container body 1 is in communication with the inside of the container body 1.

For example, a clip-shaped clamping fitting 21 is attached to the base of the article carry-in bag 19 to clamp and seal the base. This prevents communication with the outside air through the bag 19.

Reference numeral 22 denotes a drug spraying port provided on the circumferential surface of the article carry-in bag 19, and a rubber stopper 23 is provided at this port at all times to isolate it from the outside air.

This article carry-in bag 19 is for carrying articles and equipment 1 such as breeding cages, etc. necessary for breeding experimental animals in the container body 1, and is used for carrying articles of the conventional configuration shown in FIG. It replaces cylinder C.

How to use the article carry-in bag 19 will be explained with reference to FIG. 7. As shown in FIG. The rearing cage 24 is placed inside the carry-in bag 19, and the tip of the goods carry-in bag 19 is sealed by heat welding 25. Then, a disinfectant is sprayed into the goods carry-in bag 19 from the chemical spray port 22 to seal the rubber. The drug spray port 22 is closed with a stopper 23 and the rearing cage 24 is completely sterilized for a predetermined period of time. Next, the clamping fittings 21 are removed as shown in FIG. Then, using the gloves 15, the rearing cage 24 is carried into the container body 1.

Thereafter, by sealing the base of the article carry-in bag 19 with the clamping fittings 21 and cutting the heat-welded portion 25 26, the tip of the article carry-in bag 19 is opened again, so that it can be reused.

Incidentally, the end of the article carry-in bag 19 can be sealed using a metal fitting similar to the above-mentioned clamping fitting 21 instead of the heat welding 25, and in this case, the above-mentioned cutting operation 26 for reuse can be made unnecessary. .

According to the above-described embodiment, the article carry-in bag 19 has a simple structure, is lightweight, and can be manufactured at low cost, and since no excessive force is applied to the container body 1, the container body 1 will not be deformed or torn.

In addition, in its use, articles and utensils can be carried into the container main body 1 without any trouble in the same manner as the conventional article carrying tube by the above-mentioned procedure explained with reference to FIG.

Moreover, since the container body 1 and the bag 19 for transporting the goods can be folded, unnecessary space is not taken up for transport and storage.

As described above, according to the present invention, the container body is lightweight, no excessive force is applied to the container body, is foldable, is convenient for transportation and storage, and is inexpensive.
