- the automatic slide staining system 10 consists of a slide storage device 12, a slide transport apparatus 14, a first platen 16 including a plurality of staining stations 18, and a housing 20.
- Stained slides are inserted into the slide storage device or carousel.
- This carousel 12 is removably secured to a shaft (not illustrated) of a first motor (stepper motor) 22. Once the machine is activated, the first motor is initiated to provide for the shaft to rotate. The slides are then individually discharged onto slide transport apparatus in order to be processed on the various stations.
- the carousel as illustrated in figs. 1-3, has an upper portion 24 and a lower portion 26.
- the upper and lower portions are identical in size.
- Each of the upper and lower portions have an inner surface 28 and an outer surface 30.
- the inner surface of the upper portion faces the inner surface of the lower portion.
- Centrally located in each of the portions is an aperture (not illustrated) .
- a hollow rod 32 Located between the upper and lower portion is a hollow rod 32.
- the rod has a first end 34 and a second end 36. The first and second ends are received in the apertures which are located in the upper and lower portion, respectively.
- the shaft of the first motor on the staining apparatus receives the hollow rod. This provides for the slide storage device to have a horizontally disposed central axis once it is secured to the shaft.
- a plurality of radially oriented walls are provided along the inner surface of the upper and lower portion. These walls form a plurality of compartments 38.
- a retainer spring 40 is oriented between two adjacent walls for permitting releasable securement of the slide within the compartment. This retainer spring will permit for the carousal to accept slides of arbitrary thickness.
- This slide transport apparatus consists of a first pair of conveyor belts 42 and a second pair of conveyor belts 44.
- the design and structure of the conveyor belts permit a means of releasing the stained slides from the carousel and a means of transporting the slides to the various stations.
- the first pair 42 of conveyor belts are parallel to each other and are located between the carousel and staining stations.
- the second pair 44 of conveyor belts are parallel to each other and are located below and along the sides of the processing stations.
- the first pair of conveyer belts extend around a first pulley 46 and a second pulley 48 (partly illustrated) .
- the second pair of conveyor belts extend around a third pulley and a fourth pulley (neither illustrated) .
- the first pulley is located within the housing and is in the proximity of the carousel.
- the second pulley is located within the housing and is in the proximity of the first staining station.
- the third pulley is located next to the second pulley and the fourth pulley is located at the far end of the first platen.
- the conveyor belts further include a plurality of evenly spaced rods or pips 50 which protrude vertically and beyond the processing stations.
- the rods or pips in each pair of belts are in co-alignment.
- the belts start to rotate about the pulleys. This provides for the rods or pips from the first pair of belts to push on the edge of a slide in the carousel. This causes the slide to be horizontally released from the carousel and onto the belt to provide for the specimen to be traveling in a downward position.
- a roller 52 is located adjacent to the carousel to ensure that the slide in secured on the belt as it is released from the storage device. While traveling on the first pair of conveyor belts, the slide will contact a microswitch (not illustrated) . This microswitch will initiate the count of the individually transferred slides as each slide engages onto the first belts prior to the staining process.
- the slide is then transported from the first pair of belts to the second pair of belts to permit for the rods or pips from the second pair of belts to aid in the transportation of the slide by driving it to the various processing stations.
- a second motor (stepper motor) 54 is utilized to control and activate the first and second pairs of conveyor belts. This will provide for the slides to move at a constant rate of motion over the staining stations.
- the slide transport apparatus further includes an override switch for disengaging the stepper motor and stopping the movement of the slide transport apparatus when an alarm condition has been detected.
- the first platen of the automated slide staining system includes staining stations 18 having an unique design and configuration. As illustrated in the figures (figures 1 and 2), located at the corner of each station is an aperture 56. These apertures 56 allow for a staining fluid to be dispensed in a capillary form between the underside of the slide and the upper surface of each staining station.
- the stations are configured to be on the first platen at an acute angle. This acute angle aids in the flow of the staining fluid on the slide and also aids in the removal of the chemical as the slide is leaving the respective station.
- the first platen further includes a plurality of troughs 58, which are situated between each station, and reservoirs (not illustrated) , which are located in the front of the staining stations.
- a drainage orifice (not illustrated) is located within each reservoir.
- a waste tank (not illustrated) is underneath the first platen. This arrangement provides for the excess staining fluid from each station to flow into the troughs and to the reservoir. From the reservoir, the excess fluid flows into the waste tank via the drainage orifices.
- the waste tank can easily be removed from the housing via a first door 60.
- a display window 62 which is located on the front of the slide staining system, alerts the operator to empty and disposed of the fluid in the waste tank once a certain number of slides
- the last dispensing station 18a of the staining system dispenses a resin solution onto the slide. Adjacent to the last station is a heating station. After the resin solution has been dispensed onto the slide, it will travel to the heating station.
- the heating station consists of a convector 64 which will enable the resin solution to dry so that the tissue specimen, located on the slide, will be sealed. This seal creates a protective coating so that the specimen will be in a sterile and contaminant free environment.
- each slide is directed to a slide receptacle 66.
- This slide receptacle receives and maintains the slides after a complete traverse of the slide staining stations.
- the slide staining system also includes a fume extractor.
- the fume extractor removes the toxic fumes generated by the staining fluids during the dispensing cycle.
- the fume extractor consists of a plurality of openings 68, located above the staining stations, a charcoal filter within a housing 70, and an exhaust 72 having an exhaust fan.
- a cover or hood 74 is located above the staining stations in order to trap the fumes from the staining solutions. This will enable them to be extracted from the area of the staining stations by way of the plurality of the openings 68.
- the charcoal filter absorbs the toxic fumes from the staining solution, while the exhaust fan which is controlled by a third motor 76, disposes the purified fumes from the automated slide staining system via the exhaust 72.
- the charcoal filter can be remove and replaced simply by opening a second door 78 on the housing. This second door exposes the filter's housing 70 and permits for it to be open so that the filter can be removed and/or replaced.
- the staining fluid used in the automated slide staining system travels to its respective station via polytetraflouroethlyene (PTFE or TEFLON) transfer tubings 80. Each tube consists of a first end and a second end. The first end is inserted to the underside of the staining station and into the aperture. The second end is attached to a cannula tube 82.
- the cannula tubes 82 as illustrated in figure 2 and as further illustrated in figure 4 are inserted into a plurality of containers 84 containing a staining fluid. These tubes are connected to a pump 86 to permit for the staining fluid to flow from the cannula tube 82 to the aperture of the staining station via the transfer tubing 80.
- the pump is controlled by a fourth motor (illustrated but not labeled) .
- the combination of the cannula tubes and the transfer tubing is also referred to as a channel.
- Each tubing is connected to a solenoid valve 88. The valve 88 controls the directional flow of the fluid.
- valve When the valve is in a closed position, the fluid is recirculating within the channel, while when the valve is in an open position, the fluid is diverted to the aperture within a station.
- a microprocessor activates the valve, for that particular station, to an open position. This will divert the fluid and provide for that fluid to be dispensed onto the particular station.
- the second motor (stepper motor) is utilized for actuating the conveyor belts in order to guide the slides along the first platen of the staining system.
- a microprocessor located within the electric bay 90
- the microprocessor will activate the solenoid valve so that the staining fluid for a particular station can be diverted to that station.
- the solenoid valve will remain open until the slide has traveled a certain or predetermined distance, at which time the microprocessor will send a signal to close the solenoid valve. This closure of the solenoid valve will provide for the fluid to recirculate within its respective channel.
- each of the staining bottles includes an aperture 92 for receiving the cannula tube and two side walls 94, which are substantially longer than the front wall 96 and rear wall (not shown) .
- the containers are placed in a box to provide for contact to be made with the container side walls (see fig. 2) .
- This box is placed within the housing via a third door 98 (see fig. 1) of the automated slide staining system 10. This arrangement permits for the installation and replacement of the staining fluids to be made quickly and efficiently by removing the box holding the plurality of containers.
- the four digit LED display window 62 is located above the first platen 16. Located in the proximity of the display window 62 is a plurality of keys or buttons 100.
- the keys or buttons represent the number of slides which are being processed in a particular batch 106, the speed of which the slides are traveling 104, and the number of slides which can be processed by utilizing the remaining staining fluid located in the containers 102.
- the four digit LED display window will enable an operator to display the desired key indication.
- the speed at which the slides travel can be adjusted by the utilization of the speed button 104. This speed button will not only display the speed at which the slides are traveling, but will also permit the user to alter the speed.
- the storage device is removably secured to a shaft. Once secured, the operator can then activate the power supply 108 of the staining system 10 by using a button to provide for the shaft to rotate, inherently causing the storage device 12 to rotate. The activation of the system will also initiate the conveyor belts 42 and 44.
- the rods or pips 50 on the belts push or force a slide to exit the storage container 12.
- the slide is released from the storage container so that the specimen is facing in a downward position.
- the second motor 54 is used to control and operate the conveyor belts. The use of the first and second motors (stepper motors) and the arrangement and spacing of the rods or pips will permit for the slides to be released one at a time.
- the slide After release from the storage device, the slide first contacts a microswitch. The microswitch initiates the count of the individually transferred slide. After contact with the microswitch the slide is transferred to the staining stations 18 via the second set of conveyor belts 44.
- the pulses that the microprocessor uses to drive a second motor 54 which powers the second set of conveyor belts are used to determine when the microprocessor will activate the solenoid valve for a particular station. Once a slide reaches a particular and predetermined distance, the microprocessor will transmit a signal to activate or open the solenoid valve of a particular station. This will enable the staining fluid to flow to the appropriate staining station. The solenoid valve will remain open until the slide has traveled a certain or predetermined distance, at which time the microprocessor will send a signal to close the solenoid valve. The particular distance in this system for activation of the solenoid valve occurs when the slide is directly above the aperture in the station. The particular distance in which a signal will be transmitted to deactivate the system will occur when the slide exits that particular station.
- the processing of the slides is continued until the slide reaches the heating station which includes the convector 64. At this time the resin coating, which was applied at the last dispensing station 18a, is dried. This will provide for the slide to have a protective resin coating. After the resin has dried, the slide will be transported and dropped into a slide receptacle 66.
- Fig. 6 illustrates an enlarged view of the cover slip apparatus.
- the cover slip apparatus includes a receptacle or dispenser tray 110 which holds and maintains the cover slips. Internally located in the receptacle is a platform 112 (illustrated in outline) .
- This platform includes a bottom planar surface 114 while the top 116 is provided with a surface having an obtuse angle with respect to the bottom planar surface. This angle will permit an easy removal of the cover slip from the receptacle.
- a spring 118 is situated under the platform to allow for the cover slips to be spring loaded within receptacle.
- a second platen 120 is located in the proximity of the receptacle.
- the second platen includes a first end 122, a middle area 124, and a second end 126.
- the second end of the second platen is at an obtuse angle with respect to the middle area.
- the second end faces the receptacle which houses the cover slips.
- the middle portion to the first end of the second platen is linear with respect to the first platen 16.
- the middle area of the second platen is in the proximity of the first platen.
- a third pair of conveyor belts 132 are located on the edge the second platen. Extending vertically and outwardly from these belts are a plurality of evenly spaced rods or pips 50.
- a first motor attached to a first roller 128 and a second motor attached to a second roller 130 are located between the platen and receptacle. This first roller is parallel to the second roller. The second roller will remove a cover slip from the receptacle, while the first roller guides the cover slip onto the second platen. The rods or pips enable the cover slips to travel along the second platen.
- the activation of the automated slide staining system will provide for the third set of conveyor belts to be activated.
- the utilization of the second embodiment of the present invention is similar to the first embodiment, except that in this embodiment the heating station is replaced with a cover slip unit.
- the processing of the slides is continued until the slide reaches the cover slip apparatus.
- the resin coating which was applied at the last dispensing station, acts as an adhesive for the cover slip.
- a sensor detects its presence and permits for the microprocessor to activate the first and second motors. This will permit for the first and second rollers to rotate. The rotation of the second roller will remove a cover slip from the receptacle.
- the first roller will guide the cover slip onto the second platen.
- the rods or pips from the third set of conveyor belts will transport the cover slip along the second platen.
- a pressure roller is located above the second platen and applies a sufficient amount of force on the slide to ensure the cover slip adheres to the slide. After the cover slip is completely secured to the slide, it will be transported to a holding receptacle via the second platen in combination with its respective conveyor system.
- the automated slide staining system will continue to release the slides from the storage device. This will continue until all the slides have been released or if there is not a sufficient amount of staining fluid to process the slides.
- This second embodiment further includes a second sensor.
- the second sensor detects when the cover slip receptacle is empty. If the cover slip receptacle is empty, a warning will be displayed on the front panel of the LED display window.
- the cover slip apparatus includes a receptacle or dispenser tray 110 which holds and maintains the cover slips.
- This dispenser tray 110 is horizontally oriented and is maintained via a bottom box 134. This bottom box houses the electronics for the cover slip apparatus.
- a spring Internally located in the dispenser tray is a spring (not illustrated) which enables the cover slips to be spring loaded into the dispenser tray 110.
- a tension block 136 is slidably secured to the dispenser tray 110. Extending outwardly from the tension block 136 is handle 138.
- This extension is adapted to contact the spring and enable the spring to be maintained in a compressed state.
- the handle 138 permits the user to expose the dispenser tray for reloading of cover slips.
- This tension block can be magnetically held in position in order to allow the user to quickly and efficiently fill the receptacle.
- the first roller or injector roller 140 which is controlled by a motor housed in the bottom box, ejects or remove the cover slip from the receptacle to a second roller 142. Once the cover slip reaches the second roller, the rotation of the first roller ceases. Once this roller ceases, the secondary roller rotates in order to guide the cover slip to the third roller or positioning roller 144.
- This third roller or positioning roller 144 is fabricated from a durable and heavy material, such as stainless steel and is located above the secondary roller in order to ensure that the cover slip is properly positioned on the transport apparatus.
- this third roller is maintained on a pair of slots (illustrated, but not labeled) and is therefore adapted to move freely along the slots. Accordingly, when the cover slip approaches the third roller 144, it is displaced and will inherently push the cover slip forward and onto the first end 122 of the second platen 120. The cover slip will contact or catch the resin material so as to enable capillary communication between the slide and the cover slip. As the slide approaches the second end 126, a heating station 146 will enable the resin solution to dry, securing the cover slip to the slide. The activation of the slide staining system will provide for the activation of the cover slip apparatus. This apparatus operates and functions similarly as described for fig. 6.
- the last station 18a is situated below the other stations. This design and configuration will provide for a gap to exists between the stained slide and station. The resin is then dispersed quickly from the apertures (illustrated but not labeled) .
- each station and the number of stations used in the first or second embodiment can be changed in order to accommodate the testing that is desired (i.e. histology versus cytology) .
- the method involved in the processing of a histology tissue specimen using the automated slide staining system of the present invention includes a plurality of different solutions to be dispensed at each station.
- the paraffin is removed from the tissue by the use of xylene.
- the specimen is then hydrated with ABS alcohol (second station) followed by a hydration of diluted alcohol (third station) .
- the cell nuclei of the specimen is then treated with a hematoxylin compound (fourth station) .
- the next step is to remove the excess stain from the specimen using a diluted acid compound (fifth station) .
- the specimen is dehydrated by using a pure alcohol (sixth station) .
- the enhancing of the nuclear stain contrast with respect to the specimen using a dilute alkali solution (seventh station) .
- the specimen is then dehydrated by the use of pure alcohol (eight station) .
- the specimen is then stained for cytoplasm by using an eosin compound (ninth station) . Again the specimen is dehydrated, this time by the use of ABS alcohol (tenth station) . Further dehydration of the specimen occurs with more ABS alcohol (eleventh station) .
- the specimen is cleaned using a xylene solution (twelfth station) .
- a coating is applied to the slide for maintaining the specimen to be in a contamination free status (thirteenth station) .
- the method involved in the processing of a cytology tissue specimen using the automated slide staining system of the present invention includes a plurality of different solutions to be dispensed at each station.
- the specimen is hydrated with an alcohol solution.
- the specimen is hydrated again with a second alcohol solution (second station) .
- the plurality of cell nuclei of the tissue specimen is processed with a hematoxylin stain compound (third station) .
- Excess staining material is then removed from the specimen with a diluted acid solution (fourth station) .
- the specimen is dehydrated with an alcohol solution (fifth station) .
- the next step is for enhancing the nuclear staining contrast of the tissue specimen with a dilute alkali solution (sixth station) .
- the specimen is dehydrated with an alcohol solution (seventh station) .
- the next step is to counterstain the specimen for highlighting cytoplasmic cell material (eighth station) .
- the removal of the excess staining material from the tissue specimen is the next step (ninth station) .
- Counterstaining the specimen for cytoplasmic cell contrast then occurs (tenth station) .
- the specimen is then dehydrated with ABS alcohol (eleventh station) . Further dehydration of the specimen occurs with a second dispensing of ABS alcohol (twelfth station) .
- the specimen is then cleaned with a xylene compound (thirteenth station) .
- a coating is applied to the slide for maintaining the specimen to be in a contamination free status (fourteenth station) . From the last dispensing station, the slide is either transported to a drying station or to
