MODE FOR CARRYING OUT THE INVENTION

[0020] Hereinafter, examples of the present invention will be described with reference to the drawings.

Example 1

[0021] First of all, initially, a biosafety cabinet in the related art which is the premise of the present example will be described.

[0022] FIG. 1 illustrates a schematic front view of the biosafety cabinet. In addition, FIG. 2 illustrates a schematic side view of the biosafety cabinet when a cross section A-A′ in FIG. 1 is seen from right.

[0023] An opening is provided in a central area of a housing 101 of a biosafety cabinet 100, and an operation space 104 is provided therebehind. A front plate 102 is provided on a front surface side of the operation space 104 so as to block an upper portion of the opening, an operation opening 103 is provided on a lower side thereof, and an operator inserts the hands into the operation space 104 from the operation opening 103 to perform an operation. The front plate 102 is formed of a transparent material such as glass, and the operator can see an operation through the front plate. In addition, a support rod 20 lies across the operation space 104 in a width direction, and a specimen, an instrument, or the like including an infusion solution bag which is used in the operation space can be suspended thereon.

[0024] An operation stage 105 which is substantially planar is provided on a bottom surface of the operation space 104, and the operator performs an operation on the operation stage. An air intake port 107 leading downward is provided close to the operation opening 103 on a front side of the operation stage 105. The air intake port 107 is formed of, for example, a slit that extends along the operation opening 103 in a rightward and leftward direction of the housing. A back flow path 108 leading from the air intake port 107 to an upper portion of the housing is provided on a back surface side of the operation space 104.

[0025] An air blow side fan filter unit (FFU) 109 is provided above the operation space 104. The air blow side FFU 109 is formed of a fan which is rotated by a motor, and a filter, for example, a HEPA filter 109A which removes microparticles, and blows purified air, from which the microparticles are removed, into the operation space 104. An exhaust side fan filter unit (FFU) 110 is provided in the upper portion of the housing 101, and removes microparticles from a portion of air with a filter, for example, a HEPA filter 110A to exhaust the portion of air outside the device.

[0026] In FIG. 3, an air flow when the biosafety cabinet operates is illustrated with the arrows. An air flow 90 which is taken in from the air intake port 107 on a front surface side of the operation stage 105 is blown, as shown with reference sign 91, into the operation space 104 from the air blow side FFU 109 through a lower portion of the housing, the back flow path 108, and the upper portion of the housing. Since purified air from which microparticles are removed by the HEPA filter 109A of the air blow side FFU 109 is blown into the operation space 104, the operation space 104 is maintained in a purified state. At the time, if only an air flow denoted by reference sign 92 is blown into the operation space 104, air in the operation space leaks outside, which is a concern. For this reason, the exhaust side FFU 110 is provided, and a portion of air is discharged outside through the HEPA filter 110A. Therefore, a pressure in the operation space decreases, and an air flow 94 to be introduced from outside to inside through the operation opening 103 in a lower part of the front plate 102 is formed. If the air flow 94 flows directly into the operation space, the purity of the operation space decreases. However, since all of the air flow 94 flowing in from the operation opening 103 and the majority of the air flow 92 blown into the operation space are taken in from the air intake port 107 by properly controlling the air volume of the air flow 92 which is blown into the operation space from the air blow side FFU 109, and the air volume of an air flow 93 which is exhausted outside from the exhaust side FFU 110, owing to the air flow 92 blown into the operation space 104, an atmospheric barrier (air barrier) is formed to prevent the air flow 94 from flowing into the operation space 104 from the operation opening 103. Therefore, it is possible to realize an equilibrium where the operation space 104 is not contaminated by air from outside and no air leaks outside before the inside is purified.

[0027] Therefore, even though the operator inserts the hands into the operation space 104 through the operation opening 103 to perform an operation, it is possible to realize the maintenance of the purity and the prevention of contamination.

[0028] Here, there is a case where the operator uses a bottle containing a solution such as purified water, a pharmaceutical solution, or a reagent in the biosafety cabinet. At the time, if the bottle is disposed on the operation stage in the operation space, the operation stage becomes contaminated, which is a concern. Furthermore, an air flow becomes restricted, which is a concern. In addition, the operation space above the operation stage becomes small, which is a problem. Then, it is conceivable to suspend, via a bottle holder, the bottle on the support rod on which a specimen, an instrument, or the like including an infusion solution bag which is used in the operation space can be suspended and which lies across the operation space in the width direction; however, merely if the bottle is suspended, the solution does not naturally come out from the bottle, which a problem. Then, it is configured that a tube is attached to the bottle, the bottle is held in the air with the tube facing downward, a cock is provided in the middle of the tube, and the solution in the bottle can be injected into the specimen by opening the cock when necessary.

[0029] In the present example, hereinafter, a bottle holder which is capable of facilitating the exchange of the bottle with a tube will be described.

[0030] FIG. 4 is a configuration view of a bottle with a tube in the present example. In FIG. 4, 30 is a bottle main body, 31 is a bottle cap, and 32 is a tube extending from the bottle cap 31. In addition, 33 is a label that is affixed to the bottle main body to disclose contents of the bottle. In the present example, the bottle has a quadrangular column shape; however, the present invention is not limited thereto. Incidentally, a cock provided in the middle of the tube is not illustrated.

[0031] FIG. 5 is a schematic configuration view of a bottle holder in the present example. In FIG. 5, (a) is a front view, (b) is a top view, and (c) is a view illustrating a state where the bottle is mounted on the bottle holder. In FIG. 5, 41 is a front holding portion, 42 is a bottom holding portion, 43 is a rear holding portion, 44R is a right side holding portion, and 44L is a left side holding portion. Namely, the front holding portion 41, the rear holding portion 43, the right side holding portion 44R, and the left side holding portion 44L are side holding portions which hold the side periphery of the bottle.

[0032] As illustrated in FIG. 5, the bottom holding portion 42 does not cover all of a bottom surface of the bottle holder, has a bottom opening 46 for embracing at least the bottle cap 31 so as to hold the bottle cap and the tube of the bottle with a tube downward, and holds the vicinity of the bottle cap. Furthermore, the front holding portion 41 is provided with an opening 45 which continues from the bottom surface to an upper surface. Namely, if the bottom opening 46 is provided only in the bottom holding portion 42 and the opening 45 is not provided in the front holding portion 41, when the bottle with a tube is exchanged from the bottle holder, if the bottle is not lifted to the full length of the tube over the bottle holder, the front holding portion 41 is in the way, and thus it is not possible to exchange the bottle with a tube.

[0033] As described above, the bottle holder in the present example has the opening 45 that continues from the bottom opening 46 to the upper surface in the bottom holding portion 42 and the front holding portion 41. Therefore, even though there is a tube, it is possible to easily exchange the bottle. When exchanging the bottle with a tube, it is possible to realize a simple operation of temporarily stopping the solution from flowing with the cock provided in the middle of the tube, replacing only the bottle, and continuing to reuse the bottle with a tube. In addition, the opening 45 also provides the effect of being able to easily read the label 33 which discloses the contents of the bottle.

[0034] Incidentally, in FIG. 5, in the bottom holding portion 42 and the front holding portion 41, two members are separated from each other to form an opening; however, as long as the bottle can be held, only one side may be provided. In addition, the bottle holder in the present example is not limited to the configuration in FIG. 5. As long as the concept of the holder with the opening continuing from the bottom surface to the upper surface is maintained, the configuration of the bottle holder may be changed in various forms depending on the shape of the bottle.

[0035] As described above, according to the present example, it is possible to provide the bottle holder that is capable of facilitating the exchange of the bottle with a tube.

Example 2

[0036] In the present example, a configuration where a bottle holder is provided with a hook portion onto which a hook for suspending on the support rod is to be hung will be described.

[0037] FIG. 6 is a schematic configuration view of a bottle holder in the present example. In FIG. 6, (a) is a front view and (b) is a top view. In FIG. 6, the same reference signs are assigned to configuration elements having the same functions as those of the configuration elements in FIG. 5, and descriptions thereof will be omitted. In FIG. 6, the point of difference from FIG. 5 is that a hook portion 47 is provided. Namely, in FIG. 6, the hook portion 47 is provided in each of the right side holding portion 44R and the left side holding portion 44L.

[0038] FIG. 7 illustrates a state where the bottle is held with the support rod 20. In FIG. 7, (a) illustrates a state where the bottle holder is held with the support rod 20 and the bottle is suspended, and (b) illustrates the support rod 20 and a hook 48 which is an accessory thereto. The hook 48 with a non-detachable structure is movably coupled to the support rod 20, and has a U-shaped part with a U shape positioned opposite to the location of coupling to the support rod 20. It is possible to suspend the bottle holder and the bottle on the support rod 20 via the hook 48 coupled to the support rod 20 by hanging the U-shaped part of the hook 48 onto the hook portion 47.

[0039] As described above, according to the present example, it is possible to provide the bottle holder that is capable of facilitating the exchange of the bottle with a tube, and a biosafety cabinet having the bottle holder.

Example 3

[0040] In the present example, a bottle holder for a bottle which is taper-shaped on a bottle cap side will be described.

[0041] FIG. 8 is a schematic configuration view of a bottle and a bottle holder in the present example. In FIG. 8, (a) is a front view of the bottle and (b) is a front view of the bottle holder. In FIG. 8, the same reference signs are assigned to configuration elements having the same functions as those of the configuration elements in FIG. 6, and descriptions thereof will be omitted. In FIG. 8, the point of difference from FIG. 6 is that the bottle has a taper portion 34 on the bottle cap side and correspondingly, also the bottom holding portion 42 of the bottle holder is shaped to be inclined along the taper portion 34. Incidentally, in FIG. 8, the bottom holding portion 42 is formed in such a manner as to extend from each of the right side holding portion 44R and the left side holding portion 44L; however, the present invention is not limited thereto, and the bottom holding portion 42 may be formed in such a manner as to extend from the rear holding portion 43.

[0042] As described above, according to the present example, it is possible to provide the bottle holder that is capable of reliably holding also the bottle with a taper.

Example 4

[0043] In the present example, a configuration where a bottle holder is provided with a temperature regulation mechanism will be described.

[0044] If there is a temperature difference between a specimen and a solution in the bottle, when the solution in the bottle is injected into the specimen, there is a possibility of causing a temperature difference in the specimen and generating a temperature history in the cultured cells or the like. In order to prevent the possibility, in the present example, a bottle holder is provided with a temperature regulation mechanism. In particular, since in many cases, it is desirable to raise the temperature higher than a room temperature when performing an operation in the biosafety cabinet, a heating mechanism is provided as the temperature regulation mechanism. Various means such as a nichrome wire heater and a ceramic heater can be applied as the heating mechanism. A configuration view in the present example is not illustrated; however, it is possible to heat the bottle holder and to heat the solution in the bottle held with the bottle holder by adding the heating mechanism at a random location on the bottle holder. Incidentally, the bottle holder is preferably made of stainless steel due to the ease to raise the temperature and the ease to maintain a purified state. In addition, the bottle held with the bottle holder may be directly heated instead of heating the bottle holder.

[0045] In addition, since it is necessary to supply an electric power to the heating mechanism, it is possible to realize an electric power supply to the heating mechanism of the bottle holder via the support rod 20, for example, by providing an electric power supply wiring integrally with the hook 48 in FIG. 7. Naturally, the electric power supply wiring may be disposed separately from the hook 48; however, also in this case, the electric power supply wiring is preferably disposed close to the hook 48.

[0046] As described above, according to the present example, it is possible to provide the bottle holder which when a solution in the bottle is injected into a specimen, is capable of preventing the generation of a temperature history induced by a temperature difference in the specimen.

Example 5

[0047] In the present example, a specific configuration of the bottle holder in Example 3 will be described.

[0048] FIG. 9 is a specific configuration view of a bottle holder in the present example. In FIG. 9, the same reference signs are assigned to configuration elements having the same functions as those of the configuration elements in FIG. 8, and descriptions thereof will be omitted.

[0049] In FIG. 9, (a) is a top view, (b) is a front view, (c) is a bottom view, (d) is a right side view, and (e) is a perspective view seen diagonally from above. As illustrated in FIG. 9, the bottle holder is formed such that with respect to a bottle with a taper, a taper portion provided close to the bottle cap 31 is held with the bottom holding portion 42 which is inclined, the side periphery of the bottle is held with the front holding portion 41, the rear holding portion 43, the right side holding portion 44R, and the left side holding portion 44L, each of the bottom holding portion 42 and the front holding portion 41 is formed of two separated members and has an opening therebetween, and an opening continuing from a bottom surface to an upper surface is provided.

[0050] In addition, the bottle holder has a structure where the hook portion 47 is provided in each of the right side holding portion 44R and the left side holding portion 44L, and the bottle can be suspended on the support rod via the hook 48 coupled to the support rod by hanging the U-shaped part of the hook 48, which is an accessory to the support rod, onto the hook portion 47. Incidentally, the hook 48 is detachable by inserting and removing the hook portion 47 in an opening direction of the U-shaped part of the hook 48.

[0051] As described above, according to the present example, it is possible to provide the bottle holder that is capable of facilitating the exchange of the bottle with a tube, and a biosafety cabinet having the bottle holder.

Example 6

[0052] In the present example, a specific configuration of a bottle holder, which corresponds to a bottle where the bottle cap is formed to be inclined rather than facing directly upward, will be described.

[0053] FIG. 10 is a specific configuration view of a bottle holder in the present example. In FIG. 10, the same reference signs are assigned to configuration elements having the same functions as those of the configuration elements in FIG. 9, and descriptions thereof will be omitted. In addition, in FIG. 10, similar to FIG. 9, (a) is a top view, (b) is a front view, (c) is a bottom view, (d) is a right side view, and (e) is a perspective view seen diagonally from above.

[0054] In FIG. 10, the point of difference from FIG. 9 is that in a bottle, the bottle cap is formed to be inclined rather than facing directly upward. For this reason, as illustrated in FIG. 10(d), when the bottle is suspended, the bottle itself is held in an inclined manner such that the bottle cap faces directly downward. For this reason, a hook part of the U-shaped part of the hook 48 onto the hook portion 47 is configured such that the bottle is held in an inclined manner. In addition, the bottom holding portion 42 is a member extending from the rear holding portion 43, and has the function of holding the bottle from a lower surface with the rear holding portion 43 and the front holding portion 41. Since the bottle holder with the opening continuing from the bottom surface to the upper surface is formed, also the bottle holder in the present example is capable of facilitating the exchange of the bottle with a tube.

[0055] As described above, according to the present example, it is possible to provide the bottle holder that is capable of reliably holding the bottle where the bottle cap is formed to be inclined and facilitating the exchange of the bottle with a tube, and a biosafety cabinet having the bottle holder.

[0056] The examples have been described above; however, the present invention is not limited to the examples, and includes various modification examples. For example, the examples have been described in detail so as to facilitate the understanding of the present invention, and the present invention is not necessarily limited to including all of the described configurations. In addition, a portion of a configuration of an example can be replaced with a configuration of another example. In addition, a configuration of another example can also be added to a configuration of an example. In addition, the addition, the deletion, or the replacement of another configuration can be made with respect to a portion of a configuration of each example.
