Abstract

<P>PROBLEM TO BE SOLVED: To provide a depository which continuously disinfects stored objects, such as a sterilized endoscope or the like, and keeps a purification that prevents the stored objects from being covered with dust or the like even when a door is opened or closed in order to take out a stored object or the like. <P>SOLUTION: The depository 1 sucks in the open air compulsorily using a fan member 5 via an open air intake port 4. After the sucked air is disinfected and deodorized by a sterilization means 6, the air is sent to a main unit of the depository that stores storage objects which need to be disinfected and deodorized. The air within the depository is then discharged outside from an outlet port 12. Because the inside of the depository is always kept at positive pressure by making the air discharge amount of the outlet port smaller than the air sucking amount of the open air intake port, inflow of the open air is prevented even when the door of the depository is opened. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a storage for purifying, deodorizing and sterilizing the air in the storage, and in particular, in a large storage for storing and storing an endoscope of a medical instrument and the like by opening and closing the door by taking out the instrument and the like. In addition, the present invention relates to a storage that has been devised so as not to contaminate medical equipment to be stored with dust or the like as much as possible.

  Endoscopes for medical instruments in hospitals and other medical institutions must be stored in a sterilized state so that they are sterilized and disinfected after use so that dust, bacteria, viruses, and the like do not adhere to them. For this reason, a dedicated storage for endoscopes is often installed. In the case of a general sterilization chamber, a germicidal lamp consisting of an ultraviolet lamp or an ozone generating means is often used for sterilization. However, in an endoscope, a flexible synthetic material is provided to provide flexibility. Resin material is used, and when it is exposed to ultraviolet rays or ozone, deterioration such as fragility and cracking occurs due to oxidation over time, so these sterilization means are used as storage for endoscopes. It was not appropriate to use

As shown in FIG. 3, the storage has a door 22 that can be opened and closed at the front, an appropriate disinfecting means inside, and an endoscope 24 that is suspended from the internal back 23 for storage. A storage 21 exists. When the endoscope 24 is taken out, the sliding door 22 is opened, the endoscope 24 is taken out, and the door 22 is closed.
JP 2005-52199 A

  However, in the conventional storage 21 described above, since the sterilization means is provided inside, the endoscope 24 is in a suitable purification state in which the endoscope 24 is continuously sterilized when the door 22 is closed. Once the door 22 is opened, there is a risk that a large amount of dust or the like may enter the storage room 21 from outside through the wide opening. This is a problem because the endoscope 24 that has been sterilized is soiled each time the door 22 is opened and closed.

  Therefore, in the present invention, in order to solve the above-described problem, even if the stored items such as the endoscope stored inside are constantly sterilized, the stored items may be dust even if the door is opened and closed for taking out. The purpose of the present invention is to provide a storage room that can maintain a purified state with minimal contamination.

  In order to achieve the above object, the storage of the present invention forcibly sucks outside air from the outside air intake port, and disinfects and deodorizes this air by means of sterilization and deodorization, and then stores the stored items. In a storage warehouse that is sent out into the cabinet and finally exhausts the air inside the cabinet from the exhaust port, the amount of exhaust air at the exhaust port is made smaller than the amount of intake air at the outside air intake port, so It is characterized by positive pressure and prevents intrusion of outside air when the storage door is opened.

  In addition, the outlet for sending the sterilized and deodorized air into the cabinet is formed at the upper part of the door in the storage, and the exhaust is formed at or near the bottom of the door in the storage. It is characterized by forming a laminar flow of air from the top to the bottom.

  The means for sterilizing and deodorizing air is a photocatalyst and an ultraviolet lamp that excites the photocatalyst.

  The storage of the present invention forcibly sucks in the outside air from the outside air intake port, and after sterilizing and deodorizing this air by the deodorizing means, it is sent out into the storage room for storing the stored items. In the storage that discharges the air in the chamber from the exhaust port to the outside, by constantly reducing the amount of exhaust air in the exhaust port than the amount of intake air in the outside air intake port, the interior is always positive pressure, When the storage door is opened, the air pressure inside the storage is higher than the outside, so the air flows from the inside to the outside, preventing the entry of outside air into the storage, and a suitable purification state inside the storage Can be maintained.

  In addition, the outlet for sending the sterilized and deodorized air into the cabinet is formed at the upper part of the door in the storage, and the exhaust is formed at or near the bottom of the door in the storage. By forming a laminar flow of air from the top to the bottom, the laminar flow of air from the top to the bottom of the door exerts an action like a curtain that prevents the outside air from entering the inside of the cabinet. It is possible to maintain a suitable purification state in which outside air does not enter the interior when opened.

  The means for sterilizing and deodorizing the air is a photocatalyst and an ultraviolet lamp that excites the photocatalyst, so that the air taken into the storage is sterilized and deodorized to maintain the purified state.

  1 and 2 show a storage 1 according to the present invention, 2 is an openable / closable sliding door type door, 3 is an endoscope that is suspended and stored on the back of the storage 1, Outside air intakes 5 and 5 formed on both sides of the upper part of the storage 1 are arranged inside the outside air intake 4, a fan member for forcing outside air into the warehouse, and 6 is a photocatalyst plate 7. The sterilizing means 9 includes an ultraviolet lamp 8 that irradiates the ultraviolet light that excites the photocatalyst and sterilizes with the ultraviolet light itself. The sterilizing means 9 is formed by partitioning the upper part of the storage 1 by the partition wall 10, the outside air An outside air sterilization unit 11, which has an intake 4 and a fan member 5 disposed therein, is formed in a partition wall 10 near the door 2 in order to blow out the air sterilized by being taken into the outside air sterilization unit 9 toward the bottom of the cabinet. The spout, 12 is the bottom of the vault 1 Alternatively, exhaust ports formed on both side surfaces near the door 2 in the vicinity thereof, in order to make the exhaust air amount smaller than the intake air amount of the outside air intake port 4, the diameter thereof is larger than that of the outside air intake port 4. Small diameter.

  The sterilizing means 6 is arranged separately on the left and right so as to sterilize the air taken from the left and right outside air intakes 4 of the outside air sterilizing unit 9 separately. And it is produced by crystallizing titanium oxide as a photocatalyst into a prismatic shape on opposite surfaces of the photocatalyst plates 7 arranged side by side, and an ultraviolet lamp 8 is arranged between them to circulate air in this space. Yes. This sterilizing means 6 is not configured to knead and apply a binder to titanium oxide as in the conventional photocatalyst, but can be composed entirely of titanium oxide by crystallizing it and forming a prismatic shape on its surface. Due to the unevenness, the surface area increases, and the photocatalytic effect of gas components such as acetaldehyde decomposition characteristics and formaldehyde decomposition performance is extremely high. And since the ultraviolet lamp 8 of the sterilizing means 6 is located away from the ejection port 11 and does not leak ultraviolet rays into the warehouse, there is no possibility of deteriorating the synthetic resin material or the like constituting the endoscope 3.

In the storage 1 of this embodiment having such a structure, the air taken in from the outside air intake 4 in the upper right direction is sterilized and deodorized while passing through the right sterilizing means 6, and then the outlet 11. After being sterilized and deodorized while passing through the sterilizing means 6 on the left side, the air taken in from the left side portion of the slab is blown out as a laminar flow toward the bottom along the surface of the door 2 The gas is ejected as a laminar flow from the right side portion of the ejection port 11 toward the bottom along the surface of the door 2. Thereby, things stored in the storage 1 such as the endoscope 3 of a medical instrument that requires sterilization and deodorization can be maintained in a suitable purified state. This air flow exerts an air curtain function to prevent the inflow of air from outside into the storage 1, and even if the door 2 is opened, the outside air will not be blocked by the air curtain and enter the storage. Is. The air in the refrigerator is exhausted when compared to the outside air inlet 4 from the small-diameter exhaust outlet 12 to the outside little by little, thereby the internal is slightly higher positive pressure than the external pressure, for example 10~20mmH ₂ O about Pneumatic To raise.
