The present invention relates to improvements in or relating to biological sample collecting.
The collection of biological samples such as animal tissue, typically collected from the ear of an animal needs to be done efficiently and without risk of cross contamination. As an example, large herds of cows may from time to time need to be sampled at a given time. If a sampler tool and sample collectors are to be individually handled for each cow, the process can become time consuming. There is also a risk that a cross contamination of samples may occur. In addition, in order to ensure that a sample taken from an animal is not tampered with, it is important to have sufficient deterrents in place to prevent sample tampering yet at the same time ensure that matching with other animal information and/or tracking of the sample, usually retained in a sealed storage container, is possible.
Where used in this specification tissue means any part of a living thing, particularly any part made up of similar cells, or any part or parts that perform a similar function. Tissue preferably refers to any form of biological sample, from plants and animals particularly, including pigs, goats, cattle, sheep, poultry, and fish. Biological samples may include for example, animal tissue such as flesh, blood, hair, fur, saliva, sweat, urine, etc, or plant tissue such as leaves, bark, roots or wood, or any other part of a plant or animal but particularly those that are made up of similar cells, or which perform a similar function.
The present invention may be used at least for either or both of production animals and companion animals. It is anticipated that production animals may include but not be limited to bovine, pigs, deer and sheep. Further it is anticipated that companion animals may include but not be limited to horses, cats and dogs.

This invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more of said parts, elements or features, and where specific integers are mentioned herein which have known equivalents in the art to which this invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth.
The invention will now be described by way of example only and with reference to the drawings in which:
Reference will now be made to various components and variations of such components that can be used for the purposes of collecting and storing biological samples such as tissue samples from animals. Reference will first be made to the collection and storage components whereafter reference will be made to a sampler device and related components that can be utilised to take the samples using the collection and storage components.
Biological samples may be taken by the sample collectors herein described from an organism such as a plant or an animal particularly including pigs, goats, cattle, sheep, poultry and fish. In a preferred form the sample is a tissue sample that is taken from the ear of an animal.
The sample is removed from the animal by a sample collector 1, an example of which is shown in
In the example shown in
The sample collector 1 comprises a punch 4 having a body with a cutter 5 presenting a cutting end 6 that is able to penetrate into the organism to be sampled.
The cutter 5 is provided at a first end of the punch 4. The punch has an opposing pushing end 7. It is at the pushing end that the punch can for example be connected with a driver that will hereinafter be described for the purposes of pushing the cutting end (and preferably the entire collector) at least partially into and preferably through the organism to be sampled to take a sample. In the preferred form the entire sample collector 1 is pushed through the tissue to be sampled.
The body of the punch 4 preferably has a bore 8. The bore 8 extends from one end of the punch 4 to the other. It preferably extends along the length of the punch 4 between the cutting end and the pushing end 7. Preferably the punch 4 is an elongate straight body and the bore is centrally located within the punch. The cutter 5 defines at least part of this bore.
In the preferred form as can be seen in
The cutter 5 is provided at the cutting end of the punch to facilitate removal of a sample from an organism. The cutter may be attached to the punch or it may be integral with the punch so that the cutter and the punch are formed as a single part. It need not be formed to take a core sample by pushing through the organism but a sample instead taken at an edge of surface of the organism. However, being of a hollow section such as a cylindrical section offers the added benefit of the cutter being able to retain the sample as a plug. When driven into and preferably through an organism the sample becomes retained at the bore 8 of the punch. The cutter 5 preferably extends from and surrounds one end of the bore 8 of the punch at the cutting end of the punch.
In the form shown in
The plunger has a first end 10 and a second end 11. The fit of the plunger in the bore is snug yet allowing for the plunger to be slid relative to the punch. In the preferred form the plunger's outer surface is contiguous the inner surface of the bore. This ensures that a close fitting configuration is provided between the punch 4 and the plunger 9 thereby helping to prevent the ingress of contaminants from the pushing end of the punch to or towards the cutting end of the punch through the bore. The plunger and the punch are in a slidable relationship with each other. They are in a slidable relationship with each other so that a sample, once collected from the organism and retained in the bore at and near the cutting end 6 can be ejected therefrom by the plunger 9. The plunger 9 can be actuated to be displaced relative to the punch so that the second end of the plunger is displaced towards the cutting end of the punch. Preferably the first end is able to be pushed all the way to the cutting end 6 of the punch to thereby eject the sample collected from the sample collector. Actuation of the plunger may be by pushing at the first end 10 of the plunger. This may be done manually by a person pressing on it or by way of a device that will hereinafter be described. The plunger is able to be positioned in an active position as shown in
Preferably the plunger 9 includes an enlarged region 13 that prevents the plunger from being pulled out of the punch 4. The enlargement and a corresponding constriction in the bore of the punch limit the movement of the plunger and it cannot be removed by pulling the plunger from the first end out of the punch. This helps prevent external access being gained to the sample once collected and it held at the cavity or dispensed further into the storage region 15 of the storage container.
In the preferred form the actuation of the plunger causes the sample to eject from the bore and into a storage container 2 that will herein be described.
Although in the preferred form the punch is substantially tubular and a plunger is substantially cylindrical it is envisaged that the punch and plunger may be of any suitable complimentary shape. For example the bore of the punch may have a square cross section and the plunger may also have a square cross section at a slightly smaller size so that the plunger can slide within the bore of the punch. It will be appreciated that the cutting end 6 of the punch could also be of any suitable shape or size to cut a tissue sample. For example the cutting end may be of a square, oval, star-shaped or irregular shaped form.
The plunger preferably includes machine readable information such as an electronic identity (EID) tag such as a radio frequency identity (RFID) tag. The RFID configuration may be selected according to anticipated manufacturing and use conditions of the sample collector. For example a typical passive tag, active reader, system operating at low frequency can provide robust identification devices suitable for embedding in moulded plastic components at a unit cost that is low. The EID tag 14 is preferably embedded or captured or otherwise held within the body of the plunger 9. In the preferred form the EID 14 is an RFID tag. However other systems such as passive tag systems operating in the UHF range can provide similar benefits at different costs. Tags of this type are available that are claimed to be sufficiently robust for embedding in moulded plastic components. Hence in the preferred form the plunger is of a plastics material in which the EID tag is embedded. For the purposes of preventing tampering with a sample collected by the sample collector 1 without such tamper protection being detectable, the EID tag forms part of the anti-tamper provisions of the system herein described.
In the preferred form the sample collector of the present invention is provided to cooperate with a storage container 2. The storage container 2 comprises a container body 15. The container body 15 includes a storage region 16 bounded by a side wall or side walls 17 and an end wall 18. In the preferred form the end wall is closed and not openable. In the preferred form the side and end walls are integrally formed. The container body 15 is preferably made from a plastics material. It may be a moulded plastics material. A preservative may be provided inside of the storage region 16. Prior to receiving a sample the storage region 16 is preferably sealed. In the preferred form the storage container 2 also includes an end at where the sample collector penetrates the storage container, preferably in the form of an end cap 19 that is either integrally formed with or secured and preferably removably secured to the container body 15. The end cap 19 receives the sample collector 1 upon the taking of a sample.
The cap 19 is preferably threadingly engaged to the container body 15 by virtue of threads 20. The cap can be screwed onto and preferably partially ascend into the container body 15.
In the preferred form the cap has a passage 21 that has an entrance 22 and an end 23 opposed at the entrance 22. The passage 21 is of a shape and configuration to be able to snugly receive the sample collector 1. In the preferred form the side walls of the passage 21 correspond substantially to the exterior side walls of the punch 4. Preferably no gap or passage exists between the cap and the sample collector when the sample collectors is located in the passage. This helps seal the storage region 16.
Within the passage and preferably at the end 23 opposed the entrance the passage is sealed by a frangible seal 24. This could also be a plug or a membrane. The frangible seal 24, when the cap 19 is secured to the container body 15 and prior to the sample collector being received, seals the storage region 16 of the container body. The frangible seal 24 is preferably frangeably attached so that when a sample collector is given into the passage 21 it is able to push against the seal 24 to at least partially separate the seal 24 and allow for the sample to be pushed into the storage region 16. In the preferred form the sample is still retained in the bore 8 at the cutting end of the punch 4 when the frangible seal is at least partially separated to open the storage region 16. In the preferred form the sample is driven beyond the end of the cap 19 into the container body during the process of collecting and storing the sample. With reference
When taking a tissue sample the tissue to be sampled is located intermediate of the sample collector 1 and the storage container 2. Upon being driven towards the storage container 2, the sample collector 1 will start to press onto the tissue. Sufficient force will cause the tissue to be rapidly ruptured particularly where the cutting end 6 is of a sharp configuration. Continued pressure being applied will cause the cutting end of the punch to penetrate and preferably be driven through the tissue to be sampled. In the preferred form the sample collector, preferably by virtue of its cap 19 at the entrance end 22 acting to assist in a shear force type cutting of the tissue sample, will cause a sample to be removed from the animal. In a preferred form at the entrance end 22, the cap 19 presents a stop surface 25 against which the tissue to be sampled can be pressed. The side of the ear opposite to where the cutter is pressing, is supported against the stop surface 25 of the cap. It helps the shear force like cutting of the tissue from the animal.
In a preferred form the passage 21 is of a snug fit with the punch 4 so that the prospect of contaminants getting into the storage region 16 from external of the assembled sample collector and storage container is reduced and that the prospect of leakage of any of the desiccant or other content, or the leakage of blood from the sample, does not leak out of the storage region 16.
The snug fit will help prevent this, however, it may not fully seal the storage region 16. Hence in the preferred form of the invention an additional seal 26 is provided as part of the process of collecting and storing a tissue sample in the storage container 2. This will hereinafter be described.
Optionally the base of the container body may carry unique indicia 41 such as a barcode QR code matrix code or the like. This machine readable code assists in processing and/or tracking of the storage container.
Alternatively, or additionally unique indicia may be provided along the side of the storage container 2. This is for example, seen with reference to
The sleeve 28 is preferably able to slip onto the container and also couple with the cap 19. This is shown in
The ledge 33 and the lip 32 have a snap fit like engagement. To facilitate the snap fit like arrangement the sleeve 28 at its advanced end 34 (being that end that first slides onto the container body 15) includes an opening with an inwardly sloping entrance to the interior of the sleeve. This can be seen for example in
By virtue of the tension between the first region 28a and the second region 28b upon an unthreading of the cap from the container body, the first region 28a is axially drawn away from the second region 28b that is being retained to the container body. The first region 28a moves axially with the cap as it is unthreaded from the container body and the frangible webs 29 will at some stage during unthreading rupture thereby separating the regions 28a and 28b. The first region 28a of the sleeve 28 remains attached to the cap and the second region 28b is separated from the region 28a and may be retained to the container body or alternatively may just drop off the container body as for example seen in
If and when the container body is opened (by for example the threading or otherwise removal of the cap) to gain access to the sample inside of the storage region 16, it is then possible to detect the prospect that the container and/or the sample has been tampered with. If the sleeve is no longer intact and the two regions 28a and 28b are separated, this indicates that the cap has been removed from the container body. This may then indicate that the content of the storage region has been tampered with, potentially by the removal and substitution of a different sample. A cap that is put back onto the storage container in an attempt to conceal tampering can show tampering by virtue of the frangible webs having been broken.
The sleeve may include information that is preferably visible. Preferably each part includes information that may be matched (eg identical or able to be correlated to each other). the visible information may be machine readable. Alternatively the information may not be visible but still be machine readable. EID information may be carried by one of both parts of the sleeve.
In a laboratory where the sample is to be analysed, access to the sample is by virtue of a removal of the cap from the tube. In the laboratory the sleeve may be inspected to ensure it is still intact and the indicia of the sleeve may be read by an operator or maybe read by a machine. In addition, the indicia 41 on the end of the tube may also be read in the laboratory to marry up the ID's of the storage container, the sleeve and the collector RFID.
For additional protection of a sample in tube against contaminants outside of the tube reaching in the container body via the passage 21, a seal 26 may be provided to the cap 19. This can be seen in
The plug region 35 is preferably adapted and configured in a manner so that when the seal is engaged with the cap the seal is also able to push onto the plunger 9 at its exposed first end 10. In the process of engaging the seal with the cap the plunger is pushed in a manner so that it can slide relative to the punch in order to then eject the sample from the punch and into the container body 15. This is shown in
The sample collector after taking the sample and transferring it to the storage container remains engaged to the storage container until the storage container is subsequently opened. First opening desirably occurs in a laboratory. This ensures that the cutter of the sample collector is not disposed of, upon sample taking. Instead it is retained with the storage container in a safe manner that cannot cause harm.
At the time of sampling or prior to taking of the sample, the EID 14 of the plunger can be matched to the ID on the sleeve and/or on the storage container again for the purposes of helping identify whether tampering of the assembled sample collector and sample retaining storage container has occurred. This can then be checked in a lab to determine any mismatch in ID.
The punch in the variation of
The push rod 162 may be provided for the purposes of avoiding cross contamination between taking samples and avoids contact of the sampler with cut tissue and thereby prevents cross contamination upon taking sample after sample by the sampler. An assembled configuration of the sample collector 101 and container body 115 and cap 119 and seal 126 with its plunger 161 having ejected the sample 112 from the bore 108 of the punch is shown in
As well as providing a sealing function by way of plugging the passage 21 the seal 26 also provides a function of assisting in the de-capping of the container body 15. When fully engaged with the cap the seal 26 is rotationally keyed to the cap. In the preferred form this keying is provided by a toothed interface between the cap and the seal 26. It can be seen with reference to
When in a laboratory or other situation where access to the sample is desired a driver tool is able to engage with the recess 40 of the seal 26 and key therewith. The recess 40 is preferably of a shape so as to be drivable by the tool to cause the seal to rotate. The tool may be of a hex-key like nature of a kind that is commonly used in laboratory such as is commonly known as a THERMOSCIENTIFIC™ tool. By holding the storage container such as by it being keyed into a receptacle of a well tray (also commonly used in a laboratory) at the end wall 18 or side wall, the storage container will resist being rotated. As a result of rotation being applied to the seal by the tool in the recess 40, and by virtue of the seal 26 being keyed to the cap 9, the cap will threadingly disengage from the container body 15. With the first region 28a being appropriately secured to the cap 9, as the cap is removed, the first region 28a of the sleeve will travel with the cap and be separated from the second region 28a and ultimately from the container body. As shown in
The sample collector and storage container (preferably with intact sleeve attached) are able to be used as part of a system for taking tissue samples that also utilises a sampler device 300 as shown in
In
The sampler device 300 includes a cassette receiving region 304 at which a cassette can be removably received. In the receiving region the cassette is firmly held relative to the sampler device 300. A snap fit or push fit or other fit of the cassette 303 with the sampler device can be established. A lock or clip or snap fit or interference fit other securing provisions may be provided to ensure that the cassette 303 remains securely fastened to the sampler device at least during the process of the taking of a tissue sample.
The cassette may carry ID such as EID or a barcode or similar. The ID of the punch (or the seal where it carries EID) and the sample collector and/or sleeve of a cassette may be pre-matched to each other and also optionally to any ID of the cassette. Any one or more of the ID's may also be matched at the time of sampling, with ID of the animal from which the sample is or will be taken. Such animal ID maybe derived from the animal's ear tag. The cassette may also include a region where a user can write onto the cassette. This is where an animal's ear tag number may be written.
In the preferred form the cassette as seen with reference to
The sample collector and seal holding region holds both the sample collector 401 and seal 426. Preferably the sample collector and seal holding region holds the sample collector and seal by way of a magazine 309. The magazine includes separate chambers, one for each of the sample collector and seal. The magazine can move or be caused to move relative to the sample collector and seal holding region 307. The magazine, prior to sampling, preferably holds both the sample collector 401 and seal 426 as shown in
The cassette is provided for use preloaded with the sample collector, seal and storage container. Preferably the preloaded configuration presents the sample collector and the storage container in an aligned condition. Once the cassette is loaded to the sampler device, the sampler device is ready to be used.
In
The push rod 462a is engageable by the actuator of the sampler device to cause the seal 426 to be displaced from the magazine 309 when appropriately aligned with the storage container without the actuator of the sampler device coming into contact with tissue. Likewise the push rod 462b is able to be engaged by the actuator of the sampler device to cause the sample collector to be driven through the tissue without the actuator coming into contact with the tissue of the animal.
