Definitions
- the present invention relates to a suction device for closures of sample containers with the features of the preamble of claim 1.
- Such suction devices are provided in automatic systems, for example for opening blood sample containers.
- the blood samples or other body fluids to be analyzed are usually present in glass or plastic tubes, which are sealed with a rubber stopper or a screw cap.
- the sample containers are placed in a conveyor chain and individually opened by a gripper by rotating and pulling movement.
- the sealing plug n or the sealing cap removed from the sample container is suctioned off and placed in a collecting container.
- the suction device provided for this is largely identical with the vacuum cleaners known as industrial vacuum cleaners, in which a blower is placed on a storage container and the suction connection is connected to the opening device.
- a corresponding handling device for blood samples is known from DE 19517439.9.
- suction devices that work with compressed air injectors are known for the same purpose.
- large amounts of compressed air must be available, on the other hand, all of the compressed air must be filtered in order to filter aerosols out of the air. The expenditure on equipment is very high.
- This object is achieved by a device with the features of claim 1. Because the collecting container has a closure device on its underside, when the closure device is opened, the material collected there can be emptied in the form of the unscrewed or removed closures. It is advantageous for simple construction and good operational security if the closure device is designed as a flap. If it forms at least a section of a bottom wall of the collecting container, a large opening cross section of the collecting container can be achieved.
- the closure device has a substantially horizontal pivot axis and a counterweight is provided with respect to the pivot axis of the bottom wall in such a way that the closure device is closed or almost closed when the collecting container is empty, even without negative pressure.
- the closure device is preferably acted upon in operation with sample container closures and kept closed by the negative pressure, the closure device pivoting into the open position under the weight of one or more closures when the negative pressure is removed.
- the emptying of the collecting container is particularly reproducible if the closure device forms a slide in its open position, in particular in the area forming the bottom wall, from which the closures fall due to their own weight.
- the blower is a radial blower, because then a low suction power and low noise development can achieve good suction power, which can be achieved by pressure with small suction cross-sections and thus a high flow velocity in the suction channel. It is particularly advantageous for medical purposes if the device is provided with a filter that has a pore size that has a degree of separation of approximately 95% with a particle size of 0.2 ⁇ . For easy maintenance, the filter can be used as a filter cassette on the suction side of the fan.
- the blower is put out of operation to empty the collecting container, whereupon the closure device pivots under the weight of the closures into the open position, the closures fall off the closure device and then the closure device of the counterweight is at least almost pivoted into the closed position.
- the emptying can then only be initiated by switching off the fan. If, after emptying, the blower is put into operation again and the closure device is forced into its closed position by the vacuum, the device is ready for operation again after the blower has been switched on. The closed position is guaranteed by the vacuum.
- Figure 1 A suction device according to the invention in a perspective view.
- FIG. 1 shows the suction device 1 in a perspective representation with respect to the installation position obliquely from below.
- FIG. 1 shows a suction device according to the invention with a suction channel 1 which m in a collecting container 2.
- the collecting container 2 carries a filter cassette 3 on its upper side and a closure flap 4 on its underside, which at the same time forms the bottom wall of the collecting container.
- a radial fan 5 is provided on the top of the filter cassette 3, so that the exhaust air which has already been filtered is fed to the fan 5.
- the closure flap 4 which is drawn in the open state in FIG. 1, has a flat side 7, which can completely cover a lower opening 8 of the collecting container 2.
- the flat side 7 is delimited on two opposite sides by guide sections 9 oriented perpendicularly to the flat side 7, which are integrally formed on the flat side 7.
- the closure device 4 has a bearing 10 for a swivel axis 11, which is arranged in the region of a U-shaped section 12.
- the U-shaped profile 12 also carries in its end region pointing away from the flat side 7 a counterweight 13, which is arranged displaceably with fastening screws 14 m oblong holes 15.
- the pivot axis itself is finally formed.
- Extensions 16 ⁇ es collecting container 2 attached, whereby the closure device 4 m is pivotally arranged in a defined position on the collecting container 4.
- the suction device described so far can be installed, for example, in an automatic sample handling machine for automatically opening blood samples or other sample containers.
- the suction channel is guided via a tube 20 to a cap extractor.
- the rest of the suction device is mounted in such a way that the filter cassette 3 is arranged below the base plate of the sample handling device and, furthermore, a space is provided below the collecting container 2 in which a waste container or a waste bag can be arranged.
- the counterweight 13 of the closure device 4 is set so that the closure device 4 completely or almost closes the opening 8 in the idle state, ie when the blower is switched off and without the closure caps located in the collecting container 2.
- the fan 5 is put into operation and generates a negative pressure in the collecting space 2, which sucks the flat side 7 against the opening 8 and reliably fixes it there.
- the suction side of the blower is in communication with the suction channel 1 and the tube 20, which in turn opens into a device, not shown, for opening caps. Since the filter cassette 3 is arranged on the suction side of the blower 5, the entire space loaded with aerosol is subjected to a negative pressure during operation, so that any leaks can lead to secondary air entry, but not to the uncontrolled release of aerosols.
- the pressure side of the blower 5 is led outside.
- a waste container of a suitable size is located below the suction device.
- a closure cap of a sample container which is unscrewed or pulled off in the region of the opening of the tube 20 is then released by the opening device and sucked into the tube 20 by the air flow. From there it passes through the tangentially attached suction channel 1 into the collecting container 2, where the air flow slows down due to the increasing cross-section and the cap or the plug falls downward in the direction of gravity onto the flat side 7 of the closure device 4. The cap remains there for the time being. The next cap will also get there when the sample containers are opened in series.
- a filter with a degree of separation of at least 95% with a particle size of 0.2 ⁇ . The exhaust air can then be safely directed into the laboratory.
- the removed or unscrewed closures fill almost the entire collection container 2.
- the control of the sample handling machine then switches off the blower 3 for a defined period of time, so that the vacuum in the collection container 2 drops.
- the weight of the stopper on the flat side 7 of the closure device 4 then leads to the closure device 4 pivoting into the open position shown in FIG. 1, the flat side 7 and the guide sections 9 forming, as it were, a slide for the closure caps along which the closures slip into the waste bin.
- the counterweight 13 acts after successful emptying of the collecting container 2, the return of the closure device 4 in the closed position, which is fixed by switching on the fan 5 and the resulting negative pressure. The device is then ready for further closures.
- the switching off of the blower 5 required for emptying the collecting container 2 can be of a relatively short duration, for example in the range of 5-10 seconds. This time is justifiable in the usual sample handling of blood samples or the like and does not represent an interruption of the regular analysis process, because the sample tubes or sample containers accumulate in pallets and the pallet has to be changed after a certain number of opened sample containers.
- the size of the collecting container 2 can be adapted to the size and number of the sealing plugs that occur on a pallet, so that the closures of an entire pallet fit into the collecting container 2. The shutdown of the blower can then fall within the interval that is required anyway to change the pallet.
- An advantage of this procedure is that the waste container provided under the suction device can be emptied at any time without decommissioning the entire system, whereas in conventional suction devices the entire system must be switched off in order to empty or replace the all-container.
- the waste containers do not have to be resistant to negative pressure since they are not evacuated. This means that bags or sacks can also be used that can be easily and securely closed later.
- the emptying of the collecting container 2 can be controlled automatically, that the radial air fans 5 used can be operated with relatively low power and thus relatively low noise levels, and that reliable filtering, for example of pathogenic germs, is possible.
- the closure device can be opened and closed solely by controlling the operating voltage of the blower 5, so that the control of the entire automatic sample handling machine only has to provide this function.
- a suitable blower 5 is, for example, the product RG160-28 / 14N from Papst GmbH, St. Georgen, Germany.
