Description

The utility model relates to medicine and considers the design of a portable analyzer for examining a sample, in particular a biological fluid or other medical parameter, for a medically significant component. In particular, the utility model is considered as an example of a device for determining the level of glucose in the blood (hereinafter referred to as the glucometer), which includes an analyzer body with a receiver for a diagnostic strip or test strip equipped with electrical contacts at one end, an analytical zone for biological fluid and an indicator device for displaying at least one analysis result of a medically significant component. This example does not limit the possibility of using this utility model in any other portable or portable medical device, for example, for measuring pressure or cardiovascular activity, heart rate, skin moisture, means for administering medications, etc. Modern portable devices, as a rule, are equipped with an analyzer based on a processor into which a special program is “sewn up”, which processes the signals coming from the working body that correspond to one or another of the studied parameters.

From DE 10237602, G01N 33/52, publ. 03/18/2004, a glucometer for determining blood sugar is known with a reader for measuring the characteristics of a carrier with a test sample of blood and a calibration unit, with which the measuring device can be adjusted to the quality and / or properties of the carrier with the sample. It is proposed that the calibration unit includes a transmitting and receiving element that interacts with the signal source on the carrier with the sample, transmitting a signal wirelessly that reproduces the quality and / or characteristics of the sample carrier. Alternatively, it may be provided that the calibration unit includes a receiving and transmitting element that interacts with the signal source on the storage medium of the sample. In this case, the batch code or calibration data may be located in the repeater located in the wall of the box where the test strips for measurements are stored, or it may also be available on the test strip itself, or a calibration strip may be provided, the data of which is non-contact and wirelessly, the repeater can read and direct from the receiving and transmitting element to the meter, which will allow for selective or automatic calibration. At the same time, the local area of the receiving-transmitting element on the meter’s case can be marked so that, for example, it would be enough to just attach the drive to the area or it would hold it for the necessary calibration. It is proposed to use an element for a relaying system as a receiving-transmitting element, preferably for a passive relay, on which data ready for use is stored. In addition, it is proposed to provide parameters and calibration data for each test strip, so that when a test strip is inserted into the slot of the measuring device according to the invention, the transmitting and receiving element automatically analyzes it and calibrates the device.

From EP 1130383, B01L 9/00, B01L 99/00, B65D 75/58, publ. 09/15/2004, a portable analyzer is known in which test strips are located in a flexible disk and diverge in the form of rays from its center. This disk is inserted into a portable analyzer and can be moved in it step by step. At the protruding ends of the test strips there is a tip or piping that facilitates opening the package of a separate test strip when it is removed. The location of the test strips on a round disk implies the need for significant space in the instrument case. In addition, due to the round shape of the drive, the case must always have a view that provides access to the level with test strips. Additional mechanisms are required to discard the used strip. This decision was made as a prototype for the declared objects.

However, the considered examples of devices for measuring blood parameters of a patient with diabetes are devices for the rapid determination of sugar in the blood of a patient. These indications are perceived visually, after which when the device is turned off, the research values become inaccessible to medical personnel and are stored only in the memory of this device and the patient. But as the measurements increase, the previous readings are erased from the memory, since the purpose of the device is to read the current instantaneous sugar value to establish whether the patient himself has a normal level or not. As a result of life situations, it is possible when a patient with diabetes cannot control his condition or does not see a tendency to increase or decrease blood sugar readings or is in a state of panic or unconsciousness. In these cases, it is difficult for the doctor to indicate the condition of the patient immediately before the crisis in order to properly prescribe treatment. If there were statistics of measured blood sugar values in the instrument’s database or on the doctor’s computer, this could clarify the causes of the crisis. But the main thing is that the doctor could remotely monitor the patient’s condition if the measured data in the current time mode would arrive on the patient’s page.

This applies not only to a patient with diabetes. A similar picture can be observed in patients suffering from unstable or high blood pressure.

This useful model is aimed at achieving a technical result consisting in expanding the operational qualities and efficiency of a portable analyzer by providing the possibility of broadcasting the results of the study to a diagnostic and monitoring center for a patient or patient or by making it possible to accumulate statistics over a certain period of time on changes in a parameter of interest by translating the results of current measurements into the accumulation system of these results.

The specified technical result is achieved by the fact that in a portable analyzer for examining a sample, in particular a biological parameter of a person’s state, for a medically significant component containing a housing that houses a device for measuring at least one biological parameter of a person’s state or with which such a device connected remotely, the conversion unit of the analog signal received from the measuring device into a digital signal associated with the processor analyzing a device configured to process the received signal and transmit it to an indicator device for displaying in a visually perceptible form at least one analysis result of a medically significant component of the parameter under study, a short-range transceiver is located in the housing, configured to implement the function receiving a signal from the processor of the analyzing device corresponding to the result of the analysis of a medically significant component and of the parameter being monitored and with the possibility of realizing the transfer function in the current time mode or in the mode of temporarily delaying research data in a wireless mode to medical equipment equipped with a receiving unit, a computerized device, or to a mobile phone when it is in repeater mode.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

figure 2 is a rear view of a portable analyzer in accordance with figure 1 with a store for diagnostic strips or test strips;

figure 3 is a block diagram of a portable analyzer.

Figure 1-3 shows a portable analyzer in accordance with a utility model. It is assumed that this is a glucometer. A similar device (glucometer) is known. With it, the measurement of glucose in the blood is carried out by capillary soaking with a drop of blood from the fingertip of the test strip with a measuring chamber (zone for biological fluid) Test strips are disposable and have electrical conductive strips (equipped with electrical contacts at one end) and connections to analyze the requested measured values by an electronic computing device placed inside a portable analyzer. This is a known level of technology and is not the subject of description according to this invention.

According to the present invention, in the device (glucometer), the store has a flat shape, mainly rectangular, with compartments located in parallel at least in one row, in which you can place test strips and remove them from the store, holding the part used for extraction.

The store is part of the rear wall of the portable analyzer case, either inserted into it or attached to it, or inserted directly under the rear wall through the loading hole in one of the rear walls of the device into the cavity of the case.

In accordance with the invention, store compartments have a comb shape, which in width and height corresponds to the dimensions of the diagnostic strip. The length of the compartments should at least provide protection in the store for the contact surface of the test strip, while the rear end of the test strip is free and made as part to be removed.

In the presented embodiment, the magazine may be an integral part of the rear wall. In this case, the back wall on the outside will have compartments into which test strips can be inserted or inserted. The store may also consist of a retractable rear wall or a separate plate in the rear wall with the possibility of movement relative to this wall; the plate slides on the side, while the lateral placement should always be understood relative to the direction of movement. If the width of this store is less than the width of the case of the portable analyzer, then parts of the diagnostic strips used for extraction can protrude from the compartments and go beyond the edge of the store. However, the magazine’s width and the length of the protruding part of the test strip are less than the total width of the case, so that in the retracted state the magazine can be closed with a cover. To remove the test strip, it is necessary to remove the cover or open it on one side and, if it is connected to the housing on one side by a hinge, to flip it away. The magazine can also be moved forward from the side so that the part of the test strip used for extraction protrudes beyond the side wall to facilitate the extraction process.

It is possible that, next to the test strip compartments, the store also housed compartments for lancets or other accessories so that the lancets are available for replacement in the puncture device and that the user of such an instrument can remove them.

Each diagnostic strip has a measuring point on which biological fluid (for example, blood) is applied to determine the parameters. This reception area may be located on the free end of the test strip, which is available in the store or protrudes from the store from the side. The test strip can also be inserted rotated 180 ° so that the contact area protrudes or is accessible, which can be taken with your fingers to remove the test strip from the compartment. Modern systems are so insensitive that touching the applied conductive strips with your hand is not able to adversely affect the measurement result, because, as a rule, capillary channels are provided through which blood under protection is sent to the measuring area of the test strip. The receiving point can also be located on the longitudinal side, so that the sample can be obtained by easily removing a drop of blood, for example, from a finger. In this case, the part of the test strip used for extraction extends beyond the compartment and the edging of the store, which allows you to take the test strip with your fingers. There are no capillary channels or conducting strips in this region.

The utility model involves storing test strips horizontally next to each other in store compartments using the surface on the back of the portable analyzer case. In running order, the store can be closed with a lid, which must be placed on top of the store and pressed down.

If an open store version is used on the back wall of a portable analyzer, for example, in the form of a recess in the wall, then the user of this device can take test strips, for example, from the container and insert them into the compartments, forming, for example, a stock for a day or several days depending on the number of offices available. After that, he can close the lid, always having the required number of test strips at hand. To remove it, you just need to lift the lid again to gain access to the diagnostic strips. To do this, you can connect one side of the lid to the body using a film joint or a hinge of another type, which provides fastening on one side, so that it was enough to just press the lid to close access to the test strips. An edge cut out on the opposite side of the lid may engage with a locking lip in the form of a protrusion located on the side wall. To open, it is enough to pry the edge of the lid with your finger and apply enough force to open it so that the cut edge of the lid disengages from the locking protrusion of the side wall. When closed, the lid and body form an integral structure.

To ensure that the test strip can be removed without touching it with your fingers, a longitudinal slot may be present above the test strip in the lid, into which you can insert an arbitrarily moving element, one protrusion of which engages with the lower side of the corresponding test strip and when moving it with your finger in in the direction of the feed opening, push the test strip out or slide it in the opposite direction. At the same time, the slider, driven by one finger, is placed in the magazine cover in slit-like guides and grabs the test strip with its rough, sticky, or rubber-like surface so that when the slider moves, the test strip leaves the compartment. It goes without saying, the test strip can be inserted into the compartment from the outside, while the slider is captured and moved to its final position. If the store is designed, for example, for 10 diagnostic strips or test strips, then in this case it is necessary to provide 10 such ejection sliders.

The use of a flat magazine in accordance with the invention also has the following advantage: at least one wall of the magazine can be painted in a certain color. For example, it can be made of green plastic, indicating that we are talking about a store with diagnostic strips or test strips for determining the blood sugar level. Yellow, for example, may refer to diagnostic strips or test strips for measuring cholesterol. Naturally, this idea can be improved by implementing color coding to indicate means for measuring subspecies of cholesterol that can be investigated with their help. If the portable analyzer, for example, is designed for both types of use, then when you insert the magazine according to the invention, the corresponding automatic programming and automatic calibration of the device occurs. Naturally, diagnostic strips or test strips can also have a part for which the strip is removed and which is painted in the same color, making possible appropriate identification and eliminating the risk of confusion.

It was also especially advisable to place a sensor or switch in the case, which, upon detection of a magazine replacement or when loading test strips with other calibration or batch data, forces the electronic control to automatically perform a new calibration of the analyzing unit. Due to this, the calibration of the device occurs automatically depending on the batch code or the calibration data of the store with diagnostic strips or test strips from other batches.

Below are examples of specific performance of the utility model.

In the framework of this utility model, one of the possible versions of a portable analyzer is considered.

A portable analyzer for examining a sample for all examples of execution is characterized in that it contains a case with a magazine having compartments for accommodating diagnostic strips (test strips) used for analysis, having a biological fluid zone, an analyzer with a slit-like receiver for the diagnostic strip used, or a test -strips equipped at one end with electrical contacts, and an indicator device for displaying at least one analysis result significant from a medical point rhenium component.

A feature of an example embodiment of such an analyzer is that the case on the rear side is made lower (Fig. 2-4), forming a flat surface on which protrusions are made along the body or transverse to it, dividing the flat lower surface into compartments for placement of diagnostic strips or test strips and forming the store, located in parallel at least in one row, while the compartment is closed by a removable or openable lid, which is part of the case. For this embodiment, the analyzer can be made with a device for selectively extracting diagnostic strips (test strips) from the store with the cover removed or open.

The removable cover can be made in the form of a plate covering the lowering cavity, and with bent edges placed along the side walls of the casing and bearing protrusions for snapping on the edging made on the side walls of the casing. Or, the removable lid is made in the form of a plate covering the lowering cavity, and with bent edges placed along the side walls of the casing and bearing protrusions for snapping on the edging made on the side walls of the casing, while part of the plate is made to rotate or tilt relative to another part for providing access to parts of diagnostic strips (test strips) used for extraction by speakers from the departments. And for an example of the opening cover being opened, this cover can be a plate mounted rotatably on the rear wall or on the end of the housing and having tabs for snapping on the opposite side of the rear wall of the edging or on the opposite side of the side wall.

In FIG. 1 is a top view of a portable analyzer in isometric view. The analyzer consists of a housing 1, the shape of which is mainly box-shaped with rounded corners; on the upper side there is a display 2 and a control button 3. On the visible side wall, behind which is a scarifier (puncture device) 4, there are spline guides 5 for accommodating a control slider that tensiones a spring that acts on the plunger connected to the scarifier lancet 4. The lancet is removed by pressing the button 6. Next, from FIG. 1 it can be seen that the back wall 7 has a recessed notch, which according to the invention as a magazine 2 is designed, at least for diagnostic strips or test strips 8.

In FIG. 2 shows an example of a rear side of a portable analyzer. The housing 1 has a basically rectangular base shape, which also allows you to place all the elements and all the accessories necessary to measure, for example, glucose or cholesterol in the blood. The location of the scarifier 4 (puncture devices) in such a housing 1 is also known in accordance with the state of the art, as mentioned above. In this design, it is an integral part of the device and is integrated in the receiving chamber. The puncture device also has a holder in which interchangeable lancets are fixed, with the help of which punctures of skin are performed to obtain a blood sample, which is required for analysis.

According to a utility model, a magazine 9 is integrated in the rear wall 7. For this, the rear wall 7 is recessed relative to the upper and lower parts of the housing (seen in Fig. 1). On the rear wall 7 there are compartments 10 of a certain length, which are formed by the dividing walls 11 and are designed to accommodate diagnostic strips or test strips 8; the compartments are arranged vertically with respect to the longitudinal axis of the housing 1. In this example, a number of such compartments 10 are provided in which test strips 8 can be placed. Two parallel rows of compartments can also be provided. The compartments can be the same length and can be placed at the same depth. They can also have different lengths. To ensure access from the rear wall 7, the cover 12 is removed, which frees up the compartments 10 into which the necessary test strips 8 can be placed, for example, a reserve for measurements for one or several days. The compartments 10 should be formed by dividing walls so that the diagnostic strips or test strips are fixed with a slight clamping. You can also place additional compartments 4, for example, for the location of the lancet. The compartments 10 are formed during the manufacture of the housing by injection molding.

To protect the diagnostic strips or test strips 8 and remove them only if necessary, a cover 12 is provided. This cover 12 in the given example has the same width as the housing 1 and is inserted into it along the guides or clamped between the two steps of the back wall due to own elasticity. There is also an option in which the cover with a hook-shaped side edging can be closed by pressing it to the fixing thickenings on the side walls of the housing 1 and opened by prying the edging. You can also use folding mechanisms, for example, to install the hinge on one side, and the locking mechanism on the second. As can be seen, the diagnostic strips (test strips) 8 located in the closed store 9 are held in a fixed position and are protected from moisture and other environmental influences. This is an advantage due to which there is no need for additional packaging of each diagnostic strip or test strip in film.

A feature of the claimed invention is that the diagnostic strips or test strips have not only a zone for biological fluid, but also contact elements for transmitting a signal to the processor of the analyzing device. In addition, the store or diagnostic strips or test strips in the store are made with electronic elements containing information about the labeling of the batch number and calibration parameters, and a relay is placed in the housing to read the specified parameters from the electronic elements and transfer them to the processor of the analyzing device to adjust the results research. A short-range transceiver 13 is placed in the housing, which is configured to receive signals from the repeater and processor 14 of the analyzing device for transmitting and receiving data wirelessly to a computerized device or mobile phone equipped with a receiving unit.

A measuring device 15 of at least one biological parameter of the human condition or with which such a device is connected remotely, a conversion unit 16 of an analog signal received from the measuring device into a digital signal connected to the processor 14 of the analyzing device configured to process the received signal and transmitting it to the indicator device 17 for displaying in a visually perceptible form at least one analysis result significant from a medical point of view view of the component of the studied parameter

Equipping the store or diagnostic strips or test strips with marking data and / or repeaters, in which the batch number and calibration parameters are stored, allows you to configure a portable analyzer or to calibrate the analyzing device located in it. The measuring device itself, as is well known, has a display on which the measured values can be displayed by selection or also after measurement, as well as functional control buttons. To enable the reading of information from a test strip equipped with a repeater, the next embodiment of the utility model provides for the integration of a transmitter-receiver device 14 that reads information from the repeater into the device case. In this case, the data can be processed by the electronic computing device of a portable analyzer. It is also possible to transfer data to a personal computer using a transmitter using, for example, the Bluetooth interface. It is also possible to place a read-only repeater or memory device in the portable analyzer itself, in which, in addition to batch data and other receipt data, measurement data are also stored, which would be possible by using the same technology, in particular, via a transmitting and receiving element read data using a personal computer. For this, a portable analyzer, if it works using NFC technology (short-range wireless communication) and has a very small radius of propagation of sent signals, it is necessary to place mobile communication means in the field of action of the receiving and transmitting device of medical equipment (equipped with a receiving and transmitting element) or a personal computer (or a computerized means or means of mobile communication or a mobile phone when it is in repeater mode).

A repeater can also be built into the store’s wall, in which batch data can also be stored, which will allow reading them out using a portable analyzer transmit-receive device to program the device in accordance with calibration data and to eliminate incorrect measurements. The transmitter-receiver element of the portable analyzer may be an NFC transmitter that reads data from the repeater.

The store can also work in combination with a switch, which is located in the housing of the portable analyzer. When a magazine is inserted, this switch, for example, a micro switch, is activated. This switch can also be replaced with a presence detector, which works purely on the electronic principle. If the sensor or switch identifies the fact of replacement, then the corresponding signal is sent to the processor of the portable analyzer, after receiving which the calibration data is automatically read from the relays present inside or on the store. For this category of devices, a non-contact receiving and transmitting device, an NFC device (chip) is built into the portable analyzer, namely: a device (chip) using short-range wireless communication technology and having low transmit power so that it can read batch data and calibration data With the appliance, the magazine or test strip had to be brought to the instrument. Short-range wireless communication is a standardized technology and is designed to transmit data over short distances up to 4 cm from the transmitter. The repeaters used for these purposes are passive high-frequency RFID tags (radio frequency identification tag), the parameters of which are regulated by ISO 14443 or ISO 15693. NFC technology operates in the frequency range from 13.56 MHz and provides a data transfer rate of up to 424 kbit / spr very low radius of action. In this case, it is desirable that the fact of establishing communication could act as confirmation of data transmission. The NFC system is regulated by the ETSITS 102190 standard.
