The present invention describes in detail
Describe the present invention hereinafter with reference to embodiment shown in the accompanying drawing.
The equipment 10 that accompanying drawing shows comprises detachable most advanced and sophisticated 20 of the length with first opening 21 and second opening 22, container 30 with transparent part and opening 31, this opening 31 can link to each other with an opening at tip at least, soft and can rebound folding dome-shaped regulating device 40, but the air when acting mechanically on regulating device outside in the emptying receptacles, described regulating device links to each other with container, has a movable member 50 that detects surface 51, this movable member places in the container, can examine from container appearances by the transparent part of container and detect the surface.
According to the present invention, moving of movable member 50 finished by the mechanical effect of regulating device 40, can be driven as this regulating device to contact with the second portion 53 of movable member.Therefore, for promoting movable member, this contact is in the further compressive state in the second level in regulating device at least, and preferably sets up when first order compressive state is further compressed in regulating device.Embodiment has obviously satisfied this requirement, and in this embodiment, as pre-established this contact in the installation of equipment or in making, in this case in case compress described regulating device, described second portion 53 just can be by this regulating device machinery promotion.
The operation of this equipment is very directly simple.
For with the equipment filled with fluid, as shown in Figure 1, earlier unpressed softness and the regulating device 40 that can rebound are compressed to first order compressive state, then second opening 22 and most advanced and sophisticated 20 is immersed liquid to be studied, this moment, regulating device as shown in Figure 2, still remained on first order compressive state.Relieving is applied to the external pressure of regulating device, and regulating device returns to original uncompressed state as shown in Figure 1, and liquid is just by the most advanced and sophisticated detection surface 51 that flows into container 30 and wetting movable member 50.
Fully wetting or when contacting fully when described detection surface with liquid, regulating device is applied external pressure extrude liquid in the container, thereby compress described regulating device to first order compressive state, as shown in Figure 2.To the further compressive state in the second level, as shown in Figure 3, regulating device acts mechanically on movable member 50 and makes 50 to move to opening 31 directions by further compression adjustment device 40.
When compression adjustment device and mobile movable member 50, the first 52 of movable member 50 inserts the opening 31. of container when first's 52 insertion openings 31, and the removable tip that is inserted in this opening is dismantled with regard to being moved.Apply the edge that acts mechanically on most advanced and sophisticated first opening 21 and help first 52 discharge tips.Therefore the tip removes from container.As shown in Figure 3, if research contains the liquid of microorganism, remove most advanced and sophisticated equipment and can directly cultivate in this state.
Regulating device 40 has illustrated in the second level the further method of compression place lock adjustment device 40.By the self-locking action that for example elasticity thing is oppositely placed, the reverse placement as collapsible dome can realize these methods, as shown in FIG..The method of locking is less demanding and any as long as do not hinder the method for regulating device effect all feasible.
Regulating device 40 is preferably detachable.Like this, can be conveniently near the built-in member of container, for example for more detailed inspection or evaluation testing result.Therefore, under the situation of circular open 32, and described device 40 should be circumference mutually, can make suitable screw thread at described device 40 edges.Obviously, other forms of cooperation also can make regulating device detachable, as numerous frictional fit, such as, regulating device is locked in hasp on the container.
In preferred embodiments, when regulating device contacted with movable member second portion 53, regulating device 40 and movable member 50 had been set up the coupling arrangement 70 and 71 of mechanical connection.This embodiment as shown in Figure 6.In the embodiments shown, mechanical connection can pass through friction lock, as spherical hasp in the drawings.In the embodiment depicted in fig. 6, coupling arrangement locks when operation of equipment.The type that connects according to the present invention is less demanding.Preferred firm as far as possible connection when extracting movable member from container, has limited movable member and has moved with respect to any unwanted of regulating device like this.But, for understanding used locking device easily and must allow two parts 70 and 71 to rotate each other, as shown in Figure 6 embodiment by the regulating device that detachable screw thread is arranged 40 of rotation dismounting.
It must be understood that simultaneously when production or erecting equipment and just can finish connection.The function of mechanical connection remains identical, and unique difference is to be connected in advance because of regulating device 40 with movable member second portion 53, and no matter regulating device is compressive state or keeps its initial uncompressed state, and movable member all will be moved.Coupling arrangement is less demanding, and suitable coupling arrangement is clearly for reading those skilled in the art that the present invention describes, and for example can be bar-like portion 70, and this bar-like portion extends to respective aperture 71 on the movable member second portion from regulating device.Although do not allow rotation, but still keep mechanical connection firm, and make that regulating device and the integral body that places inner movable member to form are believable.
Long tip 20 embeds the opening of container and forms detachable locking by friction at this opening part of container.Therefore, being applied to the most advanced and sophisticated pressure of regulating device place release at least should be suitable with the friction force that most advanced and sophisticated head is fixed on the vessel port embedded location.Friction lock is less demanding and can set up by usual manner known in the art.Required friction for example can be only wringing fit by the most advanced and sophisticated upper end circumference that embeds opening 31 realize that as shown in drawings, or by most advanced and sophisticated snap fit (not having diagram) in vessel port, or any other suitable manner realizes.
Clearly, the tip must be enough airtight to empty G﹠W with being connected of container, so that can form required high or low pressure by regulating device 40 effects in container.Otherwise the function of equipment will be endangered and may be run into leakage problem when operating equipment.Therefore, have in the embodiment at the detachable tip on the equipment of being connected in the present invention, the tip must closely be connected with the opening 31 of container 30.
The geometric configuration of the first 52 of movable member 50 is unimportant, but preferable shape is such as allowing this first can embed opening 31, or can extrude at least most advanced and sophisticated 20, as extruding the tip by applying the part edge that mechanical force acts on first opening 21 at least.
Perhaps, as shown in Figure 3, first 52 should become definite shape so that when introducing opening 31, can tight seal opening 31.Certainly, for sealed open 31, first 52 should have the geometric configuration that is fit to form with opening 31 corresponding fluid-tight engagement on its circumference, can move the tip 20 of embedding simultaneously.Obviously, this can be realized and be not the key of function of the present invention by a lot of modes.For example, for the tubular opening 31 of circular cross sections, first's 52 preferred respective shapes that are fit to this opening.The length of described first can only be that extrude from opening at the tip that will embed 20, and does not preferably reach the required length in outside of this opening.
In another alternative embodiment, provide independently inner obturator 60 in the container.In embodiment shown in Figure 5, described device 60 uses with the opening 61 that allows liquid turnover container.When regulating device enters the further compressive state in the second level and movable member 50 when therefore mobile, obturator 60 is in opening 61 sealings and does not have the liquid can be by the position of this opening.With reference to Fig. 5, this inner obturator 60 has been described, its split shed 61 is moved to this close circumference area that device is higher.Any remaining liq is revealed by opening 31 in the taking-up of this obturator built-in movable member after allowing to detect and the prevention container.Like this, prevent remaining liquid contamination surrounding environment in any container.
In another alternative embodiment, used outside obturator 60.This outside obturator is mainly used in obturator, and regular meeting cooperates with opening 31.For example this obturator can be taked suitable shape so that the one end cooperates with opening 22, and the other end cooperates with opening 31.
Soft and regulating device 40 that can rebound is exhaust (gas displacing) member, and can be made up of the dome of elastic foldable as shown in drawings.As long as regulating device 40 can effectively raise or reduce pressure in the container, the shape of regulating device 40 is not crucial.Obviously, the shape of this exhaust component must closely be connected to container, so that regulating device 40 can be fulfiled its specific function.Though accompanying drawing is to be appreciated that to place the collapsible dome explanation of opening 32 inside this dome also can place the outside of opening 32.Equally, this dome can be replaced by other any suitable exhaust apparatus, and as corrugated tube shape (bellow-like) device, this device must contact so that it is moved with movable member equally.
The shape of the shape of equipment, especially container is not very important.But the geometric configuration of preferred container conforms to substantially with built-in movable member, because in this case, fills up the necessary liquid volume of container and will reduce to minimum.Be the space of container,, should preferably mainly occupy by movable member 50 except 33 parts that link to each other with regulating device.
