Description

Disinfecting container

Technical field

The present invention relates to a kind of disinfecting container with valving, this valving allows the medium forward of exchange in the disinfector to enter the vacuum drying stage and cuts out at last ventilating stage, and keep vacuum and sealing in the container this moment.This valving has the valve body of the flowing pressure of bearing.

Background technology

For example this disinfecting container of patent DE4111075C2 description has advantage: the material that is sterilized is preserved the long time and do not had contaminated danger in container, this is to ventilate because outside atmospheric pressure is closed up to realization randomly with keeping seal of vessel.Valve body bears preloading of spring, and the pressure that valve is in the ventilating stage disinfector to the last of enable possition increases, and valve body is pressed onto on the device valve seat, and the result obtains vacuum in the container when keeping closing.

But, in valving, must stop valve body reliably because the inflow vapor action is pressed on the valve seat prematurely, otherwise, can not carry out disinfection reliably and container even possibility implosion.It is found that the initial tension of spring of valve body can not stop it to close prematurely reliably during the enable possition, when particularly being subjected to the valve body of flow media pressure effect to have sizable surface area.Load is depended in the danger of closing too early, is high inflow velocity after all.The quantity of the material that is sterilized in the container is many more, and simultaneously required steam consumption is also big more.Disinfector is subjected to the effect by the pressure build-up of time control, that is, the constant pressure around the container increases, and also penetrates into container simultaneously, and at this moment, (gas-liquid translate phase release heat) takes place immediately in condensation.Therefore, steam " is provided " again need for container, but the condensation again immediately of this steam, and the heat that obtains up to continuous condensation makes the no longer condensation of steam in the container.

Like this, if empty is carried out disinfection, the steam required with the outside (in order to reach 134 ℃ of steam) is compared, and its inside does not need more steam substantially: valve does not bear flowing pressure substantially yet.

If the sterilization carrier, in fact more steam consumption is in inside, and this depends on the total weight and the thermal capacity of carrier: like this, must pass through the valve clearance by disinfector is predefined than the in fact more steam of empty state in the same time.Under the situation of big load, can therefore produce the danger of bump.

In the disinfecting container of common form, valve control can realize easily by at least one temperature sensor with hysteretic properties.This temperature sensor can be furnished with the chuck assembly of describing as patent DE4111075C2.This disinfecting container need not manually actuated valve and can be used for restarting sterilizing operation again after opening and taking out disinfecting substance.In order to ensure this operation, after disinfecting container taken out in the disinfector, temperature sensor must automatically reset to initial condition.One chuck assembly is arranged in the temperature sensor, reset and realize by the bimetallic hysteretic properties of temperature control.Temperature sensor and other temperature sensors with chuck design by this way: reset in the certain temperature range and realize, wherein, closed reliably by the vacuum valve of pick off control, that is, reset and can not realize before ventilating stage is finished.In chuck assembly, the temperature of setting 30-50 ℃ usually promptly, up to taking-up from disinfector with after with the disinfecting container cool to room temperature, could obtain this temperature as reset temperature.

Yet, it is found that under certain environment in disinfector, baking stage can reach preferred reset temperature 35-40 ℃.During the heavy steel tote of sterilization, because these steel totes produce very large shrinkage amount, may take place to cool off in advance, the sensor device steam that may be condensed drenches as a result.If begin vacuum drying now, condensate is caused energy loss by revaporization, and in the cooling of the place of wet steam evaporation.If this cooling realizes that in the scope of temperature sensor the end of simulation sterilizing operation can realize resetting in advance, thereby cause the wrong switch of vacuum valve.

Summary of the invention

A kind of disinfecting container, be used to keep the tote that will stand to disinfect, the described vacuum that comprises that adjusting stage, high-temperature sterilization illumination stage, vacuum drying stage and ventilating stage, this container can keep tight sealing and disinfecting process to set up of disinfecting is characterized in that:

This container has valving, and during disinfecting process, this valving allows exchange media between inside and outside the disinfecting container, and this valving comprises the closed position of the valving of the enable possition of the valving that allows Medium Exchange and prevention Medium Exchange;

Pressure outer with container and that valving is outer increases the valve body that moves, and this valve body impels valving to be positioned at the closed position;

Retainer in the valving, this retainer have the prevention position that stops valving to move to the closed position; And

Be connected the temperature sensor on this retainer, described temperature sensor under the situation that does not cause the valve closing container, operationally impels this retainer away from stoping the position based on one group of temperature.

A kind of disinfecting container, be used to remain on the tote that is sterilized of disinfection in the disinfector, described disinfecting comprises the adjusting stage, the high-temperature sterilization illumination stage, the vacuum that vacuum drying stage and ventilating stage, this container can keep tight sealing and disinfecting process to set up; This container has valving, and during disinfecting process, this valving allows the Medium Exchange between disinfector and the disinfecting container, it is characterized in that this valving comprises:

The enable possition of the valving of permission Medium Exchange and the closed position that stops the valving of Medium Exchange; And

Temperature sensor in the valving, this pick off be enclosed in the packaging part and and vessel isolation, this sensor package comprises the jam pot cover piece installing: the jam pot cover piece installing of this sensor package can be independent of the described valving of container and close, the environment of the disinfector at temperature sensor and container place is isolated, protect described temperature sensor to avoid cooling off in advance;

Described temperature sensor prevents that operationally valving from moving to the closed position until one group of temperature cycles finishing disinfector.

The objective of the invention is to guarantee the reliable vacuum seal of any required tote in the disinfecting container, even heavy steel tote.

According to a technical characterictic of the present invention, a retainer stop valve body close and before the ventilating stage that produces by pressure reduction or during this retainer inoperative.This feature has overcome the condensation problem relevant with load or process above-mentioned.

According to another technical characterictic of the present invention, stop temperature sensor to be cooled off in advance by isolating.This feature has solved the refrigerative relevant issues that shift to an earlier date above-mentioned and relevant condensation problem load or process or temperature sensor.

Heat-barrier material also can completely cut off the humidity that the condensate that drips brings reliably and insulate simultaneously, and the result is that the saturated vapor curve under the perfect condition is followed in existing temperature sensor,, only realizes cool to room temperature substantially by convection current that is.Pick off is transformed into the inside of bellows air chamber, rather than temperature sensor is arranged in the valve body top/outside.The humidity that this causes fully isolated condensate to drip and produce.

After the connection, whole pick offs is with respect to bellows space gastight closing.Obtain 95 ℃ recoil temperature in the pick off space, in the pick off space, temperature sensor can not continue cooling (no longer producing evaporation) this moment; During the bone dry, pick off space self keeps 95 ℃ of quite high temperature.As a result, in the pick off space, do not reach the recoil temperature in advance, make in desirable low vacuum and to carry out desirable vacuum drying and become possibility, like this, the conversion in advance of undesirable pick off is stoped reliably.

The more details of preferred embodiment are described with reference to the drawings, the temperature sensor of the chuck bellows air chamber inside of packing into is preferably arranged, thus isolated fully moist and hot.Like this, take to guide airy measure by the final control element of temperature.

Consequent advantage is any existence as long as wish the carrier of being dried just can be dried by the described cooling in advance that may cause malfunctioning temperature sensor to produce in the disinfector.

In the sterilization process, in the work during of different sterilisation temps as 120 ℃ or 134 ℃.The temperature sensor of disinfecting container outfit so far only adapts in two common sterilisation temps, if therefore sterilize when inappropriate vapor (steam) temperature, can not externally control the fault of generation.

Therefore, the purpose of this invention is to provide a kind of disinfecting container with valving, this valving can be carried out required switching manipulation and irrelevant with the vapor (steam) temperature in when sterilization reliably.

By in a chuck heap, providing two chuck temperature pick offs to achieve this end with different temperatures performance.Describe the design and the layout of chuck of the present invention in detail below with reference to accompanying drawing and typical embodiment.

Valving of the present invention can be arranged in any position of disinfecting container, in the sidewall as lid or groove.But valve is preferably mounted at the minimum point of the bottom of groove, and like this, during the sterilizing operation, vacuum valve is opened, and like this, condensed water can flow down.Therefore, the discharge of condensate do not need when the content of drying receptacle on the revaporization of energy loss at condensate to allow.Only in this way, just may need not consider the thermal conductivity or the thermal capacity of material therefor when producing disinfecting container, like this, for example the container made of plastics also can use.

The specific embodiment

With reference to figure 1, disinfecting container is made up of groove 10 and lid 12.This groove has tilting bottom 14 and annular base frame 16.(see figure 3) between sealing ring 18 with L shaped cross section is installed in the top edge of groove 10 and covers 12.The sealing ring utilizes its inside jointing angle to press to cover in 12 the cannelure 20, thereby realizes downward sealing.Therefore, sealing ring 18 correctly is locked in horizontal direction, and the result does not need bonding, without any need for effort, just can convert sealing then and there to.Even, after fixing for a long time, the sealing part can be bonded on the groove slightly, and correct locking makes to cover at sealing member does not unclamp and be removed from covering, and the sealing part has the double containment seat: end face contact on the one hand (particularly when container be not under vacuum, and only be to close by fastener), but as pressure increase (when pressure reduction produces), sealing member moves forward into the cavity of closing with circular pattern specially, like this, vertical surface has also sealed.

The middle body that gets deeply stuck at groove 10 has through hole 22, is used for the outflow of Medium Exchange and condensate.Valving 24 is arranged in this middle section of container bottom 14, this valving 24 has the sealing ring 26 that cooperates with ring-shaped valve seats 28, and this valve seat 28 forms and be positioned at the outside of through hole 22 by the bottom of groove, therefore, after the valve-off 26,28, content in the container and outside atmosphere are isolated.Sealing ring is carried by the valve plate that is subjected to feed pressure control and this valve plate forms valve body together.

As can see from Figure 1, trench bottom 14 has one to have the cone wall part 30 of through hole 22 in the zone of valving 24.This design makes valving be contained in the base regions top of pony sill 16.Form porose 34, one bonnets 36 in central plane part 32 and insert wherein from the below, this bonnet 36 is made up of rotatable symmetric high-grade steel part and mechanically is fixed on the wall part 32 by turn Fastener 38 and circlip 40.Turn Fastener 38 is the rotatable securing members of ellipse, is installed on the bonnet by circlip 40.Turn Fastener 38 turns over after 90 °, and bonnet is crushed on the bottom land.Head 42 by projection is realized locking.But will around bonnet flange 44 bottoms below the planar section 32, be welded to airtightly on the bellows 46 of an axial compression.Bellows 46 lower ends are pointed to outer annular lip 48 and are welded to the valve plate 50 that high-grade steel is made by adapter ring 52.Sealing ring 26 is installed on the excircle of valve plate 50.Become outwards conical and the flow guiding disc below through hole 22 54 is placed on the valve plate, make the condensate that spills from through hole 22 turn to the outside rather than be collected on the valve plate 50.Valve seat rings 26 is made by elastomer such as silicones, and bonded or sulfuration is at the correct position of valve plate 50.

Described sealing ring also can be placed on the valve seat 28 of trench bottom.Valve plate 50 has a vent 56, and it is closed hermetically by the seal disc 58 that the leaf spring 60 that is welded on the valve plate 50 presses.These parts allow the valve internal cavity as check-valves be spatial ventilation in the bellows 46.In the space that bellows 46 surround, the bowl 62 with female thread is welded on the correct position of valve plate 50.The base portion of this bowl 62 have with valve plate 50 in the centre bore 64 that aligns of vent 66.Described air vent 64,66 is covered by exit seal dish 68, and the sealing dish is positioned at the base portion of bowl 62 and is designed to as shown in Figure 7 shape.Two openings that it has circle section form have the net that is covered with described air vent 64,66 between two openings.

Lid 74 have a female thread that externally threaded annular wall 72 is screwed into bowl 62.The lower annular end face seal ground of annular wall 72 stops the edge of exit seal dish 68.Therefore according to practical situation, sealing dish 68 has two functions, on the one hand, closes vent 64,66 when there is malleation in valve internal, on the other hand, and the part 62,72 that sealing screws in each other.

Lid 74 has a centre bore 76, and the groove that holds sealing ring 78 is arranged in the hole 76, realizes the spatial ventilation of valve internal by this centre bore.Steel spring plate 80 is welded on and covers 74 correct position, as shown in Figure 6, is bent the otch 84 that overlaps onto dish 80 by the spring 82 that stops of its generation, and this otch 84 is positioned at the top of the centre bore 76 of lid.This stops that spring 82 is designed to a leaf spring, carries one and stops pin 86, and this pin has the V-arrangement opening, is used to stop flowing pressure to make the bump of valve generation, will further specifically describe below.Prevention pin 86 is connected with leaf spring 82 by a pressure pin 88, and the outstanding downwards valve ball 90 that enters centre bores 76 and polishing of pressure pin 88 interacts, and the valve seat of valve ball 90 is formed by sealing ring 78.

Round temperature sensor, this housing is that condensate that the heat insulation prevention simultaneously of temperature sensor is dripped enters the temperature exchange with the chuck temperature pick off by bowl 62, lid 74 and the housing that forms of bonnet 36, bellows 46.This can a model by a kind of chuck realize; described chuck keeps valve open, and time closes when the control temperature reaches " heat " (by check-valves ventilation), because the protection of seal; have only after (valve is prepared next time and used) finished in seal of vessel (vacuum) and cooling, open again.

The following inversion temperature of temperature sensor is available, as:

134 ℃, between the period of heating: 30-50 ℃, cooling period: this valve works at each disinfecting process that arrives 134 ℃.

Shortcoming: if as 120 ℃, it can not operate (it is never located at switch " connection " certainly).

120 ℃, between the period of heating: 30-50 ℃, cooling period: this valve works in the limited scope in 120 ℃ of processes and 134 ℃ of processes, though dangerous: if valve is closed the pressure of the air chamber of bellows no longer may further raise (can only ventilate) at 120 ℃; Up to 120 ℃. obtain 2.1hpa (saturated steam curve).If container 134 ℃ of process sterilizations, makes pressure further be increased to 3.2-3.4hpa now.This pressure increases (gap is 1.1-1.3) can compress bellows, but can not penetrate into container, and the result causes, and does not perhaps reach correct sterile environment in the container, and perhaps container quits work and implosion through pressure difference.

At hospital disinfection, 134 ℃ and 120 ℃ of temperature ranks that process is two standards.User must have different valve (being used for 120 ℃ or 134 ℃), will install or change these valves before using.This is possible, and is pretty troublesome and make mistakes easily.The chuck assembly that describes below is avoided this shortcoming by the valve that is designed for all general sterilization levels.

Valve ball 90 is supported by senior steel plate, and just plate raises up into the part sphere, and valve ball is welded on the hemisphere jut.The influence that the shape of this senior steel plate 92 is not changed by temperature and pressure can only be by interacting to move with the chuck that describes below in the space that annular wall 72 limits.These chucks are made by the temperature control bimetallic, it is characterized in that, because the influence that lags behind is transformed into relative case of bending in default heating-up temperature, reset fast in low inversion temperature cooling period.See among Fig. 5 that the chuck that describes below is in case of bending under the room temperature of setting.Near the relative direction bending of the chuck 94 of senior steel plate 92 to steel plate 92, and to fovea superior.This chuck 94 typically has following inversion temperature.

Between the period of heating, chuck 94 is bound to 115 ℃ salient position from concave position.Cooling period, be returned to 95 ℃ concave position fast from salient position.

Near chuck 94 be another chuck 96, its transfer characteristic is different from the transfer characteristic of chuck 94.The installation site of chuck 96 is corresponding with the installation site of chuck 94, and its bearing-surface raises up and contacts fully with chuck 94.Temperature control bimetallic chuck 96 typically has following inversion temperature: between the period of heating, chuck is bound to 117 ℃ salient position from concave position.Cooling period, be returned to 35 ℃ to 50 ℃ concave position fast from salient position.

Near chuck 96 be another senior steel plate 98, steel plate 98 upwards depression conforms to the curvature of the chuck of insertion; Steel plate 98 does not change its shape and only changes its position.

Near senior steel plate 98 be another be bent upwards the projection chuck 94A, this chuck 94A has identical transfer characteristic with chuck 94.Chuck 96A is bent upwards projection near this chuck 94A, has identical transfer characteristic with chuck 96.Chuck 96A is supported by senior steel plate stable on another space 99, and these steel plate 99 bendings raise up, and its curvature just in time conforms to the curvature of described chuck.This senior steel plate 99 is useful on the hole of improving the steam inlet, and its circumferential edges is supported on the exit seal dish 68.Adapter ring 52 is formed for providing the pad of distance between the annular lip 48 of bellows 46 and the valve plate 50, and in all cases, described adapter ring 52 is connected on these parts airtightly by welding, mode such as bond or be threaded.

Among the figure,, only show the chuck of determining function in all cases for clear.In the practice, all situations is favourable with the identical chuck of a plurality of equidirectional installations down.

The function of valving 24 is described below with reference to Fig. 4-13:

Be heated to during 115 ℃, chuck remain on shown in the Figure 4 and 5 the position.Arrive 115 ℃, chuck 94 and 94A are transformed into relative bending position as shown in figure 10.In this process, the position of its total height and valve ball 90 does not change.

When reaching 117 ℃ of second inversion temperatures, chuck 96 converts relative bending position shown in Figure 11 again to 96A.The position of the total height of described heap and valve ball 90 remains unchanged, thereby makes valve ring 26 keep mentioning from valve seat 28, that is, valve stays open.Medium Exchange can continue to carry out without barrier like this.

According to the present invention, in the sterilizing operation process,, takes on valve following measure for being remained on the enable possition, and be about to flowing pressure and be loaded on the valve body that forms by valve plate 50, this low pressure attempt overcomes spring prestressing force valve-off.Shown in Fig. 8 and 9, upwards act on part that pressure on the valve plate 50 moves this valve plate and its support is run into bonnet 36 up to the prevention pin 86 that remains on obliquity by means of spring 82 step 100 from the bottom.This stop position can be found out from Fig. 8 and 9.Flow gap between valve seat 28 and the valve ring 26 also remains on this position, and Medium Exchange can be carried out by expedite continuing.Therefore the bump of container has been avoided reliably, like this, any desirable tote can both be in disinfector as the quick sterilization of hope, and do not destroy the possibility of container.

During the cooling stage, chuck 94 and 94A are transformed into about 95 ℃ position shown in Figure 12, and the curvature of chuck 96 and 96A remains unchanged.Thereby this causes the expansion lifting valve ball 90 of chuck heap, and as this position of Figure 12, valve ball leans against on the sealing ring 78, from top closing valve space.

During moving upward, as shown in figure 12, ball 90 stops pin 86 by pressure pin 88 liftings, makes to stop pin upwards straight, thereby can enter bonnet 36 like a cork.Between disinfector internal pressure decrement phase, with respect to the internal pressure of container and valve space, external pressure reduces gradually, realizes pressure compensation by the valve of still opening 26,28, by check-valves 58 or vent 56, may realize the pressure compensation in the valve pocket.In the temperature sensor further evaporation-vacuum cooled no longer occurs then, therefore, avoided reliably in advance, the conversion of undesirable pick off.

Ventilating stage in the end, in case the pressure in the disinfector increases once more, bellows press down the scope that is reduced to increase at the pressure reduction of setting up in effect, valve 26,28 is closed, and in the case, as shown in figure 13, stops pin 86 to enter the inside of bonnet 36.This operating period, bellows 46 are compressed.Owing to keep in the disinfecting container vacuum and atmospheric pressure to keep valve closing, further cooling period and remove disinfecting container in the disinfector after, valve 26,28 remains on this closed position.By suitably determining the size (cross section and elastic stiffness) of valve clearance or bellows, the vacuum level that is obtained can change in very wide scope.

Be cooled to during the inversion temperature (as 35 ℃ to 50 ℃), chuck 96,96A are bound to relative bent position, and valve ball 90 lifts from its seat as a result.In this process, valve space ventilates by vent 66, but interior of the container is not ventilated.Valving self is maintained in its closed position the secondary ventilation valve that does not show in by figure up to atmosphere pressure energy and penetrates into disinfecting container with the filter that is connected at its upstream.Because the elastic reaction of bellows 46 and the effect of gravity, valving returns to the position shown in the Figure 4 and 5, and disinfecting container does not need hand control just can be used for sterilizing operation next time.

Figure 14 and 15 has shown another exemplary embodiments.Here the function of the valving of Xian Shiing corresponds essentially to the function of the embodiment shown in Fig. 1-13.Compare with above-mentioned exemplary embodiments, the conversion of this valving is: second ball valve replaced exit seal dish 68.This ball valve is made up of the valve cup ring 104 that inserts in the vent 66, and this valve cup ring 104 is fixed by dish 102 and interacted with valve ball 106, and this valve ball 106 is welded on the senior steel disk 99 of bend relief.This steel disk 99 makes valve ball 106 lift from its device by spring 108 prestrains.Other springs 110 act on the senior steel disk 92 at top, make valve ball 90 be pressed in the enable possition in advance.Like this, vent 66 is often opened.Up to being transformed into and corresponding position shown in Figure 15, the position of Figure 12, vent is closed.In fact, existence is different with first exemplary embodiments: i.e. after the chuck conversion, this chuck housing is closed fully along both direction.

Figure 16 and 17 has shown another preferred embodiment of the present invention.Here the function of the valving of Xian Shiing is corresponding substantially with the function of embodiment shown in 1-15.Compare with above-mentioned exemplary embodiments, this valving has changed: stop pin 86 to be replaced by a brace 86A, this brace 86A be a pivotal mounting and by be biased in the prevention position by leaf spring 87 with the axle 87 in the mounting blocks 85.Extension 83 is handled by valve ball 90, in case make that chuck 94,96 is handled, brace 86A just rotates the not prevention position of Figure 17.
