Description

The present invention relates to a vinyl isolator, and more particularly to a tube wire band for fixing an inner cap and an outer cap of the vinyl isolator.

In recent years, vinyl isolators have been mainly used as germ-free animal breeding devices. Aseptic loading and unloading of materials to and from the vinyl isolator is performed via a steryl lock and using an inner cap, an outer cap, a connecting sleeve, and the like. These fixation methods are extremely practical issues. The outer cap and connecting sluice are fixed with a special vinyl tape, but this was processed with reference to the attached Scotch tape when the 1950s isolator technology was introduced to Japan, and as one of the rationalization in recent years, general-purpose tape has been used. The question is whether it can be used. The inner cap is fitted with a brim to make it easier to put on and take off inside the isolator, and the fixing was initially made by cutting the waste tube of a large car into round slices, but with reference to this, it was processed as a special rubber band at the factory. Things have been used since then.

As mentioned above, the inner cap has been fixed by processing it as a special rubber band at the factory. In recent years, due to the deterioration of this rubber band, problems such as the inner cap being blown off (disengaged) have been seen during spray sterility, and countermeasures are required.

Sufficient airtightness and pressure resistance to withstand unexpected impacts are essential for fixing caps and the like of germ-free animal breeding equipment. However, as far as the present inventor knows, there have been no reports on these fixation methods so far. Therefore, we measured the leakage rate as airtightness and the disconnection pressure as pressure resistance of the inner cap, outer cap and connecting sleeve of different fixing methods, and examined the fixing method of caps and the like from the viewpoint of aseptic breeding equipment.

That is, it is an object of the present invention to provide a means for immobilizing an inner cap of a vinyl isolator, which solves the above problems at least partially.

The present inventors evaluated the performance of immobilization using various bands in order to solve the above problems. The present invention provides a vinyl isolator with an inner cap immobilized by a tube wire band. The present invention includes the following embodiments 1-5:

This equivalent or equivalent can also be used.

[First Embodiment]
FIG. 1 shows a steryl lock to which the tube wire band of the first embodiment is attached. A tube wire band secured the vinyl covering the steryl lock. This configuration can be used as an inner cap or an outer cap of a vinyl isolator. The opening of the steryl lock was covered with vinyl, and the tube wire band was wrapped around it in close contact with the opening. The winding may be one-time winding, one-and-a-half winding, two-time winding, two-and-a-half winding, three-time winding, three-and-a-half winding, or the like. The number of windings can be adjusted according to the thickness of the steryl lock. In one embodiment, the number of times the tube wire band is wound around the outer cap or the inner cap is double winding (double winding).

In certain embodiments, the inner cap is, for example, a cap applied to the inside of the steryl lock shown in FIG. In certain embodiments, the outer cap is, for example, a cap applied to the outside of the steryl lock shown in FIG. In the present specification, the inner cap means a cap composed of a vinyl portion that covers and seals the steryl lock from the inside and a means (tube wire band) for fixing the vinyl. In other words, the inner cap includes a vinyl portion and a tube wire band of the present invention. In the present specification, the outer cap means a cap composed of a vinyl portion that covers and seals the steryl lock from the outside and a means (tube wire band) for fixing the vinyl. In other words, the outer cap includes a vinyl portion and a tube wire band of the present invention. The vinyl portion of the inner cap or the outer cap may be appropriately provided with an opening for a vent or the like. See, for example, FIG.

[Second Embodiment]
As a second embodiment, components can be added, omitted, or modified as appropriate to the vinyl isolator. For example, a connecting sleeve secured with vinyl tape may be added to the vinyl isolator.

Other configurations of the vinyl isolator may be those conventionally known. That is, the vinyl isolator of the present invention may have all or part of the configuration normally provided by the vinyl isolator.

Vinyls used in vinyl isolators, such as vinyl chloride membranes, are flexible, have high elongation, and are generally transparent or highly transparent. In addition, the vinyl used for the vinyl isolator can be bonded by high-frequency electromagnetic waves and is easy to handle. The vinyl film used may be 0.3 to 1 cm thick, for example 0.4 to 0.8 cm, for example 0.4 to 0.6 cm, for example 0.5 cm to 0.55 cm, but is not limited to this. In addition, the dimensions and shape can be designed according to the target vinyl isolator. As the vinyl film, a known one or a commercially available one can be used, and examples thereof include, but are not limited to, those of Achilles Corporation. When manufacturing a vinyl isolator, a vinyl joining machine is used to join (also called bonding or welding) vinyl to vinyl. The vinyl joining machine melts and joins the bonded parts by high-frequency heat. High frequency heat is generally applied by a high frequency welder device.

Vinyl isolators usually include an air supply port, a breeding room (also referred to as a chamber), and an exhaust port. The air supplied from the air supply port needs to be sterile, and a filter is generally used for this purpose. The filter is for removing microorganisms, viruses, etc. in the outside air to realize sterility. The filter medium of the filter may be the filter medium FG-50 or a HEPA filter. Aseptic air is supplied from the air supply port, supplied to the germ-free animals bred in the breeding room, and then exhausted from the exhaust port. A trap can be installed at the exhaust port. Gloves for internal operation may be attached to the breeding room. The operation in the breeding room is basically performed through gloves. Also, vinyl isolators generally have steryl locks for feeding animals and food. Alternatively, in some cases the vinyl isolator may have a germany trap. In the steryl lock, the outer cap is generally provided with two vinyl tubes, which can be closed with a rubber stopper or the like. When sterilizing Steril Lock, remove the rubber stopper, spray the sterilizing solution from one vinyl tube, wait for the mist to be discharged from the other vinyl tube, close the rubber stopper, spray a certain amount of sterilizing solution, and then the rubber stopper. After spraying the sterile solution, close the spout. See Figure 2 for the general configuration of vinyl isolators.

Items are basically taken in and out of the breeding room under aseptic conditions via steryl lock. The steryl lock has caps (closures) on both sides. When carrying in an item, open the outer cap, sterilize the outer surface of the item and the breeding room, close the outer cap, sterilize the inside of the steril lock, and then open the inner cap to carry in. Bring in things. After that, the inner cap can be closed. When carrying out items, sterilize the inside of the steril lock, open the inner cap, move the items to the sterilized steril lock, open the outer cap after closing the inner cap, and close the outer cap after carrying out the items. .. Also, the inside of the steryl lock can be sterilized. See, for example, FIG.

The connecting sleeve can be used to connect the two vinyl isolators. Alternatively, the connecting sleeve can be used to connect the vinyl isolator to the sterile or transport can. A schematic diagram of the connecting sleeve is shown in FIG. The connecting sleeve has two connecting ports on the left and right. The central part can be a vinyl film. In addition, a disinfection port can be provided in the central vinyl portion. In addition, a working window may be provided in the central vinyl portion as the case may be. The connecting port of the connecting sleeve may have the same or substantially the same dimensions (diameter) as the steryl lock to be connected. The connecting port portion of the connecting sleeve can be made of the same material as steryl lock, for example, hard vinyl chloride, or aluminum, but the material is not limited to this. The left and right connecting openings and the central vinyl portion of the connecting sleeve can be sealed and fixed with vinyl tape. For example, it can be sealed and fixed by wrapping vinyl tape three times or more.

A HEPA (High Efficiency Particulate Arrestance) filter is a filter that can capture particles with high efficiency. According to the JIS Z 8122 standard, "a particle collection rate of 99.97% or more for particles with a particle size of 0.3 μm at a rated air volume". It is defined as an air filter that has a performance of 245 Pa or less and has an initial pressure loss of 245 Pa or less.

The vinyl isolator may be of normal size, large size or small size. Fasteners can be of various dimensions depending on the purpose. In certain embodiments, the vinyl isolator is a device for large animal rearing, such as for monkeys, pigs, chickens, dogs, and cats. In certain embodiments, the vinyl isolator may be commercially available from Gic Co., Ltd., an equivalent product thereof, or an equivalent product thereof.

Vinyl isolators are also commonly used with sterile cans to move their contents in and out. Sterilized cans can be attached to vinyl isolators so that their contents can be placed in a vinyl isolator or the contents of a vinyl isolator can be transferred to a sterile can while maintaining a sterile condition. In addition, vinyl isolators are commonly used with transport cans to transport germ-free animals in and out of the vinyl isolator. The transport can can also be attached to the vinyl isolator so that the germ-free animal can be transferred to the device or removed from the vinyl isolator while remaining sterile.

The sterilized can can be attached to the vinyl isolator by, for example, the following method. (i) Remove the outer cap of the vinyl isolator. (ii) Disinfect the steryl lock and connecting sleeve. (Iii) Attach the connecting sleeve to the steryl lock and fix it with vinyl tape (sealed). (Iv) Disinfect the other side of the connecting sleeve and the Lumirer film portion of the sterile can. (V) Connect the connecting sleeve and the sterile can and fix with vinyl tape (sealed). Disinfection can be performed, for example, by spraying Expore (manufactured by Claire Japan), Neopore (manufactured by Claire Japan), Acrofine (manufactured by Gic) or peracetic acid. FIG. 5 shows a schematic diagram of the sterilization operation when connecting the connecting sleeve to the steryl lock.

The vinyl isolator can be manufactured by a conventionally known method, for example, the method described in Non-Patent Document 2. The entire contents are incorporated herein by reference.

(Example)
Materials and methods The inner cap, outer cap, and connecting sleeve were laminated and bonded with a high-frequency welder ²⁾ , and the processed one was used. Steril Lock used a transparent vinyl chloride welded outer diameter of 31.5 mm and a length of 15 cm.

The fixing method is as follows: (i) Silicon rubber band (width 16 mm, thickness 4 mm, length 60 cm, custom-made, Kokugo Co., Ltd., Tokyo, hereinafter new rubber band), (ii) Silicon rubber band used for 1 year. (Hereafter, old rubber band), (iii) Metal band (D-318, Thickness 0.7 mm, Width 13 mm, Diameter 30 cm, Fine clamp, Tsukiji Seisakusho Co., Ltd., Tokyo), (iv) Wire band (SW300 diameter 3 mm wire) Clamp, Tsukiji Seisakusho Co., Ltd., Tokyo), (v) A band in which the above wire is passed through a silicon tube with a diameter of 10 mm through the wire band of (iv) above (hereinafter sometimes referred to as a tube wire band, see Fig. 1). , And (vi) 6 conditions without band. For the outer cap, (i) vinyl tape (thickness 0.2 mm, width 25 mm, length 20 m, for vinyl isolator, Nitto Denko Co., Ltd., Tokyo) triple winding, (ii) general-purpose tape (thickness 0.2 mm width, 19 mm length, 10 m vinyl tape, Denka Co., Ltd., triple winding, (iii) Filament tape (width 0.2 mm, width 19 mm, length 50 m filament tape, Nichiban Co., Ltd., Tokyo) triple winding , (Iv) No tape, (v) Tube wire band and (vi) Vinyl tape were triple-wound, and the condition of double-wound wire was added from above. For connecting sleeves, (i) vinyl tape and (ii) tube wire band fixation were compared.

In the airtightness test, the normal pressure of the isolator is about 100Pa, but in order to clarify the difference, the leakage rate (Vol%) under the four conditions of 100Pa, 300Pa, 500Pa and 1000Pa with reference to ^{the airtightness test 5,6) of the glove box etc.} / h) was measured. The leakage rate (Vol% / h) was calculated by dividing the differential pressure Pa before and after the measurement by the atmospheric pressure of 1013 hPa and multiplying by 100, and the temperature and atmospheric pressure were calculated without any change of 1013 hPa. For the measurement, an outer cap was attached to one side of the steryl lock, the filament tape was triple-wound, and the wire was double-wound and fixed from above. A rubber stopper with a bicycle tube English valve was attached to one side of this cap to serve as a pressurizing port, and a rubber stopper with a silicon tube was attached to the remaining pipe for internal pressure measurement. A pressure compressor (ACP-50 Ryobi Co., Ltd. Hiroshima) was used, and a multi-environment measuring instrument (testo435 Co., Ltd.-Kanagawa Prefecture) was used for internal pressure measurement. The test cap was attached to the opposite side of the steryl lock and fixed by the target fixing method. The internal pressure of steryl lock was continuously measured 11 times per minute for each condition four times, and the average was calculated.

As for the pressure resistance test, after performing the above airtightness test, the inside of the steryl lock was further pressurized, and the pressure at which the cap or the like came off was measured. This deviation pressure was measured 6 to 11 times for each condition, and the average was calculated. A pressure gauge (testo512-4 differential pressure gauge Co., Ltd., Kanagawa Prefecture) was used for pressure measurement of 6 kPa or more.

In addition, the laboratory controlled the temperature at 23 ° C and humidity at 60%, and in the airtightness and pressure resistance test, the temperature, humidity, atmospheric pressure, and carbon dioxide concentration were measured at the same time as the pressure with the IQI probe.

Results 1. Airtightness test Table 1 shows the results of the leak rate = Vol% / h of the airtightness test of the inner cap, outer cap and connecting sleeve by different fixing methods.

The leakage rate of the new rubber band fixing of the inner cap was 0.004 vol% / h at 100 Pa pressurization, 0.130 at 300 Pa, 0.377 at 500 Pa, and 1.003 vol% / h at 1000 Pa. As it became older, it increased to 0.029 vol% / h at 100 Pa pressurization and 0.482 vol% / h at 500 Pa. The 100 Pa of the metal band was 0.016 vol% / h, and that of the wire band was 0.001 vol% / h. The 100Pa pressurization of the tube wire band was 0.000 vol% / h, 300Pa was 0.100 vol% / h, 500Pa was 0.250 vol% / h, and 1000Pa was 0.783 vol% / h. Without band, it showed 0.118 vol% / h at 100 Pa.

The leakage rate of the vinyl tape fixing of the outer cap was 0.000 vol% / h at 100 Pa, 0.027 vol% / h at 300 Pa, 0.098 vol% / h at 500 Pa, and 0.253 vol% / h at 1000 Pa. General-purpose tapes of 100Pa and 300Pa were similar to vinyl tapes, but 500Pa had high values of 0.172 vol% / h and 1000Pa had high values of 0.927 vol% / h. Further, the double winding of the wire from the top of the filament tape fixed for the test had the same value as that of the vinyl tape. 100Pa without tape was 0.041 vol% / h.

The pressure of 100 Pa for fixing the vinyl tape on the connecting sleeve was 0.000 vol% / h, and that of 1000 Pa was 0.323 vol% / h. When one side was a tube wire band, 100Pa was 0.000 vol% / h, 300Pa was 0.058 vol% / h, 500Pa was 0.206 vol% / h, and 1000Pa was 0.631 vol% / h.

2. Pressure resistance test Table 2 shows the results of the release pressure when the inner cap and outer cap are pressurized by different fixing methods.

Looking at the inner cap, it came off at 0.8kPa without a band. The release pressure of the new rubber band was 4.4 kPa, and when it became old, it was 1.4 kPa. The disengagement pressure of the metal band was 16.1 kPa and the wire band was 14.2 kPa, which were extremely high. However, the band tightening position was scratched. The tube wire band was not scratched and the detachment pressure was 14.1 kPa.

The outer cap came off at 0.6 kPa without tape. The release pressure of the vinyl tape was 11.0 kPa, and that of the general-purpose tape was 8.0 kPa. The filament tape had a high release pressure of 22.6 kPa and the tube wire band had a high release pressure of 17.2 kPa. In addition, the wire double-wound fixing on the filament tape for the test did not come off even at 22.0 kPa. In addition, there were cases where one winding was not sufficient for the tube wire band, and two windings (double winding) was optimal, but even if the number of windings was increased, the effect was sometimes reduced. ..

Discussion The pressure leakage rate and pressure release pressure of the inner cap, outer cap and connecting sleeve by different fixing methods were measured. The leakage rate of the inner cap was in the order of no band> old rubber band> metal band> new rubber band> wire band> tube wire band. For the outer cap, the order was no tape> general-purpose tape> vinyl tape> filament tape> tube wire band. Vinyl tape was superior to tube wire bands in connecting sleeves.

The removal pressure of the inner cap was in the order of no band> old rubber band> new rubber band> tube wire band> wire band> metal band from the lowest. For the outer cap, the order was no tape> general-purpose tape> vinyl tape> tube wire band> filament tape.

Regarding the problem of inner cap skipping, the release pressure of the new rubber band was 4.4 kPa, and the leakage rate of 0.004 vol% / h for regular 100 Pa seemed to be acceptable as a sterile breeding device. However, when it became old, the deterioration was obvious with a detachment pressure of 1.4 kPa and a leakage rate of 0.029 vol% / h. Ishihara et al. ⁴⁾ Introduce a non-degrading metal band for isolators. The decoupling pressure of the metal band was 16.1 kPa and the leakage rate was 0.016 vol% / h, and the pressure resistance was sufficient. However, in the case of metal bands, it has been shown that metal can damage the cap. Next, regarding the airtightness and pressure resistance of the special vinyl tape, the results superior to those of the general-purpose tape were obtained. The newly prototyped tube wire band does not damage the cap, has high airtightness and pressure resistance, is easy to attach to the steryl lock in the isolator, and can also be used for fixing the outer cap and connecting sleeve. .. It is expected as a new fixing method for inner caps and outer caps for vinyl isolators.

Regarding airtightness, the leakage rate of the glove box is 0.25vol% / h or less at negative pressure of -500 to -700Pa ^{5, 6)} . The leakage rate of isolators for sterile preparations is 0.5 vol% / h or less ^7,8) . The leak rate of the inner and outer caps under normal 100 Pa pressurization was 0.25 vol% / h or less even without the band and tape, and the leak rate further decreased when fixed. The outer cap was fixed at all 300Pa and 500Pa, and the vinyl tape and tube wire band were 0.25vol% / h or less even at 1000Pa. 300Pa of the inner cap was all fixed, and at 500Pa, the tube wire band was 0.25vol% / h. It was presumed that the airtightness around the steryl lock of the isolator was relatively high compared to the isolator for sterile preparation and the groove box.

Next, regarding the problem of pressure resistance, the disconnection pressure of 600Pa or 800Pa without the band and tape does not disengage at the regular 100Pa. However, assuming an unexpected impact, deterioration of the cap, etc., dirt, etc., it cannot be practically fixed. In addition, the pressure resistance is surely improved by fixing. The release pressure of the vinyl tape is 11 kPa, the rubber band is 4.4 kPa, and the tube wire band is 14.1 kPa. Isolators can be considered safe as a response to unforeseen impacts. Although it is a problem of deterioration of the rubber band, it is conceivable to replace it in advance or use multiple pieces. It is expected that the inner cap skipping will be improved by selecting a fixing method with high pressure resistance. However, it cannot be prevented if the air pressure of the spray compressor is ^{2 to 4 kg / cm 2 3).} It can be said that there is no choice but to perform the basic operation of visually observing the degree of expansion. The airtightness and pressure resistance of the inner cap, outer cap and connecting sleeve by different fixing methods could be obtained numerically. These results are expected to contribute to isolator technology.
