Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a carrier vehicle used in, for example, a hospital,
The present invention relates to a structure capable of transporting a sterilized surgical instrument or therapeutic instrument while reliably maintaining its sterilized state.

(Prior Art) Generally, surgical instruments or therapeutic instruments are sterilized in hospitals and external sterilization centers and transported to the clinics or operating rooms for use. The sterilization condition must be maintained until just before the operation.

Therefore, in order to safely transport the sterilized object while maintaining the sterilized state, a vehicle having a structure in which the main body for storing the sterilized object of the vehicle is sealed and transported, or a fan is attached to the outer surface of the main body, Transport vehicles having a structure that prevents the inflow of outside air are known.

(Problems to be solved by the invention) However, in the conventional carrier having a structure for sealing the main body,
When the airtightness of the main body is broken during transportation and the outside air flows inside the main body, there is no means to confirm the maintenance of the sterilized state of the sterilized object, so the sterilized state of the sterilized object is not guaranteed. is there.

Further, in a carrier vehicle having a fan, electricity is required to rotate the fan, so that the main body is equipped with a power source to increase the weight of the main body, or a power supply cord is attached to an outlet on a building wall or the like. Therefore, there are problems that the moving range of the carrier is restricted and the structure is complicated in order to connect with the vehicle.

In view of the above-mentioned problems, an object of the present invention is to provide a transporting vehicle having a simple structure that can be moved to an arbitrary place and can confirm the maintenance of a sterilized state of an object to be sterilized.

[Constitution of device]

(Means for Solving the Problem) In the transport vehicle of the present invention, a transport means is provided in a main body having a storage portion inside, and a closable flow port communicating with the storage portion is formed in the main body. An opening communicating with the main body is formed in the main body, and the opening is closed by an elastic film having stretchable airtightness.

(Operation) In the transport vehicle of the present invention, after storing the object to be sterilized in the storage portion 2 of the main body 1, aseptic air is forced into the storage portion 2 through the circulation ports 13 and 14 to close the opening 6 of the main body 1. When the feeding flow ports 13 and 14 are closed until the elastic film 7 expands and bulges outside the main body 1, the main body 1 is sealed in a state in which the elastic film 7 bulges, and the storage part 2 is shielded from the outside. It Next, in this state, the main body 1 is moved to the target place by using the conveying means. Then, when the items to be sterilized are taken out and the circulation ports 13 and 14 are opened, the elastic film 7 returns to its original planar shape when it is biased by the elastic force generated by the swelling, so It is possible to prevent a part of the aseptic air to be filled from flowing out through the circulation ports 13 and 14 to prevent the outside air from flowing into the storage unit 2 and to take out the sterilized object from the storage unit 2.

Further, if the bulging shape of the elastic film 7 is unchanged before and after the movement of the main body 1, it means that there is no air circulation between the storage part 2 and the outside of the main body 1. Have been maintained before and after the transportation.

(Embodiment) An embodiment of the carrier vehicle of the present invention will be described with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1 is a box-shaped main body, and the inside of the main body 1 serves as a storage portion 2 for the object to be sterilized. Two are attached each.

A circular opening 6 communicating with the storage portion 2 is formed on the upper surface 5 of the main body 1, and an elastic film 7 having elasticity and airtightness such as rubber is sealed at the opening edge of the opening 6. The opening 6 is closed.

A door portion 9 is provided on the side surface 8 of the main body 1 so that an object to be sterilized can be taken in and out of the storage portion 2. And
A packing is attached to the rear edge portion of the door portion 9 so that the door portion 9 is attached to the main body when the door portion 9 is closed.

On the front surface 10 and the rear surface 11 of the main body 1, a handle portion 12 as a conveying means for a person to walk around the main body 1 at the time of conveyance is provided on the upper portion thereof, and a storage portion 2 is provided on the lower portion.
The distribution ports 13 and 14 that communicate with the
Distribution pipes 15 and 16 having an opening / closing means are connected to 13 and 14.

Further, a sensor (not shown) for the pressure gauge 17 is provided in the storage section 2.
Is attached to the pressure gauge 17, and the pressure gauge 17 measures
It is designed to be displayed on the upper part of the side surface 8.

In this way, the transport vehicle 18 is configured with the above configuration.

Next, the operation of this embodiment will be described.

First, for example, after sterilizing the main body 1 in a sterilization center in a hospital or outside, a sterilized female, tweezers, gauze or other surgical instrument or therapeutic instrument to be sterilized is placed on the door of the main body 1. 9 is stored in the storage part 2 and the door part 9 is closed. Next, the distribution pipe 15 is closed to close the distribution pipe.
16 is opened, and aseptic air 19 is forced to flow into the storage section 2 through this flow pipe 16. This sterile air 19 is sealed in the main body 1 except the circulation port 14, so that the pressure of the storage part 2 gradually becomes higher than the pressure outside the main body 1 as the main body 1 flows into the storage part 2, and the storage part 2 and the main body 2 are closed. 1 A pressure difference is generated between the outside and the outside. Further, the elastic film 7 is expanded due to this pressure difference, and aseptic air 19 is flowed in until it is expanded to the outside of the main body 1. Next, in this state, when the flow pipe 16 is closed, the elastic film 7 swells, and the pressure in the housing 2 is higher than the outside, the main body 1 is completely sealed, and the housing 2 is shut off from the outside. It That is, the sterilized object is in a state in which its sterilized state can be maintained.

At this time, the display of the pressure gauge 17 is read to confirm that the pressure in the storage unit 2 is higher than the atmospheric pressure.

Next, the main body 1 is moved to, for example, an operating room or an examination room by using the caster 4 which is a transporting means and the grip portion 12.

Next, when the object to be sterilized is taken out from the storage section 2, the elastic film 7 is used.
It is confirmed that the bulging shape of No. 1 is unchanged, and the pressure of the containing portion 2 indicated by the pressure gauge 17 is unchanged.

In the unlikely event that the bulging shape of the elastic film 7 changes as compared to when the object to be sterilized is stored and the degree of bulging is small, or the pressure in the storage portion 2 is reduced, the main body 1 Since the airtightness of the container is broken and the storage part 2 communicates with the outside of the main body 1 and there is air circulation between the storage part 2 and the outside of the main body 1, the object to be sterilized by the air flowing in from the outside. May be contaminated.

That is, the bulging shape of the elastic film 7 is a means of a simple structure for visually confirming the maintenance of the sterilized state by the transportation of the sterilized object.

Then, after confirming the sterilization state of the storage unit 2, when the items to be sterilized are taken out and the flow ports 13 and 14 are opened, the pressure in the storage unit 2 is higher than the outside of the main body 1, so that the storage unit is filled. A part of the aseptic air that has been discharged flows out through the circulation ports 13 and 14 to prevent outside air from flowing into the storage unit 2. That is, the object to be sterilized can be taken out from the storage unit 2 while being kept in a sterilized state immediately before it is used, and is transported without being contaminated.

As described above, the transport vehicle 18 has a simple principle of sterilization in which the airtightness of the main body 1 is checked to determine whether the sterilized state of the storage unit 2 is maintained, based on whether or not the bulging shape of the elastic film 7 has changed. Since the main body 1 is provided with a state confirmation means and no power supply or power supply cord is provided, it is lightweight, its structure is simple, and it can be moved to any place.

In addition, in the above-mentioned embodiment, the inflow of aseptic air into the storage portion 2 was made to flow only from the flow pipe 16, but the flow pipe 15 is not limited to this, and the flow pipes 15 and 16 are supplied from both sides. Sterile air may be introduced. Further, when a part of the sterile air is discharged, it may be discharged from either one of the flow pipes 15 and 16.

Further, the opening 6 that is closed by sealing the elastic film 7 is
Not only the upper surface 5 but also the front surface 10, the rear surface 11, or the side surface 8 of the main body 1.

Further, the transporting means is not limited to the casters 4 and may be an appropriate transporting means.

[Effect of device]

According to the present invention, the airtightness of the main body during transportation and before and after transportation can be confirmed by the simple principle structure of whether the bulging shape of the elastic film is changed or not. I can confirm.

Further, if the bulging shape of the elastic film when the object to be sterilized is sealed in the storage chamber is unchanged, the object to be sterilized can be transported by the transportation vehicle while reliably maintaining the sterilized state.

Also, in order to prevent outside air from flowing into the storage part of the main body,
The structure is simple and lightweight because it does not have a fan, a power supply for it, or a power supply cord and only the main body is sealed, and it can be moved to any place.
