The present invention relates to a kit holding adapter for holding an analyzer for analyzing a target analyte together with a sampling tool for taking a sample.
Analyzers are used in various fields for analyzing a target analyte. For example, analyzers are used for measuring a target analyte in blood in the medical or sports field, or for analyzing ingredients in foods in the field of foods, and for determining the degree of pollution in water, soil or air in the environmental field.
For the above-described analysis, it is necessary to perform a sampling operation for collecting an enough amount of sample. For example, when an individual measures the glucose level in his or her blood, a sampling tool is used for collecting a sample (blood). A generally available sampling tool is a lancing device utilizing a lancet. The lancet of the lancing device punctures a finger or forearm for bleeding from the skin, whereby the blood is supplied to the analyzer for concentration measurement. In determining the glucose level in blood, use may be made of a personal blood sugar measuring device, for example, to which a measuring sensor may be fitted.
In self-measurement of the blood sugar, use needs to be made of a lancing device, a lancet, a personal blood sugar measuring device and a measuring sensor. Though these components are used as a set for measurement, blood sugar measurement is not always performed at home, so that the set owner must take the trouble of carrying all of the components needed for blood sugar measurement when he or she goes out. In addition, a risk of forgetting or losing part of the components will increase with an increasing number of components to be carried.
Recently, components for blood sugar measuring have been reduced in size for improving their portability. However, a diabetic also needs to carry insulin and an injector in addition to the components necessary for blood sugar measurement. Thus, the above-described problem is even more remarkable especially with respect to diabetics, and there is a greater need for improving the portability of blood sugar measuring components and the like.
As one solution to the above-described problem, JP-A-2001-524680 discloses a measuring device with a cutting implement. This measuring device includes a connector for removably attaching the cutting implement to the measuring device. The connector may be provided for example by forming a V-shaped dent on the measuring device for embracing engagement with the cutting tool, or by providing a clip on the cutting tool for engagement with a groove formed on the measuring device. In this way, the measuring device and the cutting tool, though two components, may be carried as one unit for improving their portability.
However, the measuring device with the cutting implement needs the connector to connect the measuring device and the cutting tool. Due to this structure, the connector can not be used for existing measuring devices or cutting implements (sampling tools), nor improve the portability of a specific measuring device and sampling tool which the user is currently using.
Further, if a large impact is applied to the measuring device with the cutting implement upon dropping, the connector may be damaged or deformed and therefore becomes no longer usable for connection to the cutting implement. For instance, in the case where the connector comprise a dent or clip, it is no longer possible to connect the cutting implement to the measuring device if the dent or clip is damaged or deformed.
An object of the present invention is to improve the portability of components (such as an analyzer or a sampling tool) needed for sample analysis on a long term basis.
According to the present invention, there is provided a kit holding adapter which is designed for holding an analyzer for analyzing a target analyte in a sample together with a sampling tool for taking sample.
The adapter may include a first holding portion for holding the analyzer and a second holding portion for holding the sampling tool.
The adapter according to the present invention may include a main body for holding the analyzer and the sampling tool, and an article holding portion for containing articles (e.g. analyzing sensors or lancets) used for at least one of the analyzer and the sampling tool, or other items (e.g. medication such as insulin, an injector, or a sterilizing tool) used in conjunction with the sample analysis or the sampling.
The main body preferably includes a first holding portion for holding the analyzer and a second holding portion for holding the sampling tool.
At least one of the first and second holding portions includes an opening for partly exposing the analyzer or the sampling tool for enabling at least either the analysis of the sample by the analyzer and the sampling by the sampling tool while the analyzer or the sampling tool is held by the adapter.
The first holding portion and the second holding portion may be separated by a partition wall which is formed with a cutout for connecting an inside of the first holding portion and an inside of the second holding portion.
The article housing portion preferably includes a plurality of containing rooms. The article housing portion may be removably attached to the body, so that the adapter can be reduced in size to provide improved portability when the article housing portion contains nothing. Alternatively, the article housing portion may be integrally formed with the body as one piece.
Each of the holding portions and containing rooms of the kit holding adapter according to the present invention may be colored differently. For example, the first holding portion may be colored red, the second holding portion may be colored yellow, a first containing room for housing non-used analyzing sensors may be colored green, a second containing room for housing non-used lancets may be colored purple, and a third containing room for housing used analyzing sensors and lancets may be colored black. In this way, the user can empirically and visually find out missing items at once, thereby facilitating timely supply of the missing items.
The adapter of the present invention can hold the analyzer and the sampling tool together and contain other items to compactly carry all components and items necessary for measurement. Thus, the burden on the user is reduced in carrying components needed for analysis such as blood sugar measurement.
This advantage may be obtained without making improvements or modifications to the analyzer and the sampling tool. Depending on the sizes of the particular analyzer and sampling tool which the user is currently using, a selection needs only to be made from a plurality of candidate adapters to best suit the particular combination of adapter and sampling tool, or an adapter is manufactured to suit the sizes of the components owned by the user. Analyzers, sampling tools, and other necessary components for analysis may vary in size from supplier to supplier. An adapter according to the present invention may be manufactured in a custom order manner to suit the particular combination of components owned by the user, using a mold selected from a plurality of candidate molds each prepared in advance to suit the size of each existing component.
An adapter according to the present invention is applicable to an analyzer and a sampling tool regardless of their model, type, year of manufacture, and supplier. Thus, the adapter of the present invention can be used to hold an existing analyzer and sampling tool together for carrying to improve their portability, so that there is no need for purchasing an integratable measuring kit.
Preferably, the adapter should at least have such a configuration as to stably hold the analyzer and the sampling tool while also facilitating subsequent removal of the thus held components. For example, each of the first and second holding portions includes an inner surface which is depressed and bulged to conform to the outer surface of each component. Due to this structure, the analyzer and the sampling tool are stably held by the kit holding adapter, so that they hardly play during transport or in use.
The adapter of the present invention may be provided with a spacer between the outer surface of the analyzer and the inner surface of the first holding portions as well as between the outer surface of the sampling tool and the inner surface of the second holding portion. In this way, the analyzer and the sampling tool are held stably in the first and second holding portions.
Each of the spacers may be formed separately from the main body or as a plurality of protrusions projecting from the inner surface of each holding portion.
A separate spacer may be selected from a plurality of spacers each prepared in advance to suit a different configuration. In this way, the adapter can stably hold the analyzer and the sampling tool regardless of the configuration of the analyzer and sampling tool. The separate spacer may be formed of an elastic material. Such a spacer is deformable to fit to the outer surface of the analyzer or the sampling tool, thereby stably holding the analyzer or the sampling tool.
On the other hand, in the case where a plurality of protrusions are provided to work as a spacer, unnecessary ones of the protrusions may be bent or removed for causing the remaining necessary protrusions to press the analyzer or the sampling tool, thereby stably holding these components. Preferably, the plurality of protrusions include plural kinds of protrusions having different heights.
The adapter is not limited in its outer configuration, but it should preferably be rounded as a whole. Such a configuration allows the user to comfortably grip the adapter while facilitating its insertion into a bag or pocket.
An adapter according to the present invention is typically made of plastic or metal. The adapter may also made of metal and provided with a thin plastic coating. Though the plastic coating provides an added thickness, it also provides abetter touch feel. Further, the adapter may be made of an elastic material such as rubber or silicone for serving the purpose of holding the analyzer, the sampling tool, and the other items as long as it substantially retains its shape.
However, since the adapter is desired to have a strength enough to avoid breakage due to dropping, it should be preferably made of a shock-resistant material. For avoiding any damage, peripheral portions of the adapter may be fitted with an elastic material for absorbing impacts. For better portability, the adapter is preferably made of a weight saving material. Thus, the thickness of the adapter is selected in view of the demand for a weight reduction besides the requirements for withstanding external forces upon a fall. The thickness may be about 0.1 mm to 2.0 mm, depending on the material.
An analyzer held in an adapter according to the present invention is not limitative. For example, the adapter may be applicable to an analyzer of the type which requires mounting of an analyzing sensor, or of another type which does not require mounting of an analyzing sensor. An analyzing sensor is not limited to such a type that utilizes an oxygen reaction or an antigen-antibody reaction, but may be of the type which utilizes a chemical reaction. Further, a detection method in the analyzer is not limitative, so that the detection may be based on an optical method or an electrochemical method.
A sampling tool to be held in an adapter according to the present invention is not limitative. The sampling tool needs only to collect a sample necessary for analysis in the analyzer. Examples of sampling tools include a lancing device, a pipette or syringe used for reliably sampling a liquid.
Preferred embodiments according to the present invention will be specifically described referring to the drawings, by taking as an example an adapter for holding a blood sugar measuring device (as an example of a measuring device) and a lancing device (as an example of a sampling tool).

Spacers may also be formed as shown in
As shown in
As shown in
The kit holding adapter X1 holds the blood sugar measuring device 4 and the lancing device 5 together, thereby facilitating carriage by an user. The article housing portion 3 may contain e.g. biosensors 45 and lancets 55 used for the blood sugar measuring device 4 and the lancing device 5. Thus, the adapter X1 may be used to carry all items necessary for blood sugar measurement, thereby reducing the likelihood of leaving or losing necessary items for blood sugar measurement.
The kit holding adapter X1 can hold an existing blood sugar measuring device 4 and an existing lancing device 5 for improving the portability of the existing blood sugar measuring device 4 and lancing device 5. This advantage may be obtained without making improvements or modifications to the existing blood sugar measuring device 4 and lancing device 5, or without requiring. Further, there is no need for the user to newly purchase a measuring device integrated with a lancing device.
Next, a kit holding adapter X2 according to a second embodiment of the present invention will be described referring to
