Definitions
- the present disclosure relates to a disposable medical article/accessory article that can be inserted into or coupled to a medical device.
- the present disclosure relates to a set of disposable medical items (disposable item set), a medical device, in particular an infusion pump, to or in which a disposable item can be connected or used, a medical system that has a disposable item set and a medical device, a medical Method and a computer-readable storage medium according to the preambles of the independent claims.
- Medical devices such as infusion pumps, require disposable medical items or accessories for operation and therapy of a patient, which are inserted into this device before the start of treatment.
- specific disposable items can be selected, inserted and used accordingly in the medical device from a large number of disposable items that can be used, as required and adapted to the patient.
- the type or type of disposable item used by the user is usually associated with the required therapy or the patient access used.
- a variety of different types of disposable infusion devices may be used in a volumetric infusion pump. In addition to administering medication, this can also be the administration of enteral nutritional solutions via the stomach, which are fed to the patient by means of a disposable infusion device.
- GUI graphical user interface
- the medical devices are not able to prevent such a selection and such an operation. No special handling of potentially unsafe or critical combinations of infusion disposables and medications (or other data) selected from the medication database is provided for in the infusion pump operating sequence.
- a disposable item with UV protection should be used if the medication that is conveyed through the disposable item is UV or light-sensitive.
- the state of the art therefore lacks an intelligent connection between single-use items on the one hand and drugs with corresponding drug data on the other hand, which can include drug-specific standard settings and range limits for the infusion parameters.
- a further sub-task is to ensure that access to medication and/or incompatible settings is restricted on the basis of a single-use item that is used or inserted, in order to reliably prevent errors.
- a further sub-task in particular can also be seen in not allowing an unsafe combination of disposable item(s) and medication(s) in order to prevent possible application errors.
- a basic idea of the present disclosure is that a disposable medical item/accessory item, such as an infusion tube, is designed in such a way that it has at least one predefined, integrated marker as a recognition feature/identification feature. If this single-use article is then used in a medical device (that is, picked up or connected), then the identification feature is detected via a corresponding detection system of the medical device. The medical device can then use the detected identification feature to draw conclusions about the disposable item, in particular its identification (e.g. a class or type or ID of the disposable item) and/or a position of the disposable item (e.g. to check whether it is correctly connected). In particular, based on the detected Identification feature then be an adjustment of a drug selection and / or a selection of another (suitable) disposable.
- identification feature e.g. a class or type or ID of the disposable item
- the present disclosure describes a technical principle for recognizing the disposable item (accessory element), in particular a disposable infusion item, and a resulting adaptation of the medical device behavior/device behavior, in particular by means of filtering a medication database and/or a disposable item data record. This results in an intelligent check and adjustment, so to speak, which increases the safety of patient treatment.
- the medication database can be filtered on the basis of the disposable item selection or the detected disposable item.
- the ergonomics of operation such as manipulation of the medication database in the user interface (UI), of the medical device, in particular the infusion pump, can be improved in this way.
- access to medicines and other settings, in particular in the medicines database can be limited on the basis of the single-use item inserted. Unsafe combinations of disposable items and medication can also be prevented to prevent application errors.
- Another advantage is that the disposable items and disposable item sets, as well as the medical device and systems, enable new concepts due to the possibility of combining pump therapy forms with the use of specific disposable items (e.g. a special disposable item set for the PCA Therapy).
- Recognition or a mechanism for recognizing the single-use item, in particular a single-use infusion item allows the medication database of the medical device, in particular on the infusion pump, to be used ergonomically through the use of filters or filter mechanisms. In particular, unsafe combinations of infusion disposables and drugs are prevented.
- Advantageous embodiments are claimed in the dependent claims and are explained in particular below.
- the disposable item has an integrated marker as a recognition feature/an identification feature.
- a disposable medical item in particular a medical hose or a medical slide clamp, is provided for use in a medical device, in particular an infusion pump, which is characterized in that the disposable medical item has at least one integrated marker as a recognition feature , wherein the at least one marker is a predetermined section of the disposable item with a (special) color (from a predefined, discrete set of colors, each of which has a property assigned to it) and/or a predetermined section of the disposable item with a (permanent) magnetization or a material with a magnetic effect and/or a predetermined section of the disposable article with a predetermined geometric shape, in particular in the form of indentation patterns, and/or a section of the disposable article with a predetermined conductivity and/or r is an embedded RFID tag.
- the at least one marker is a predetermined section of the disposable item with a (special) color (from a predefined, discrete set of colors, each of which has a property assigned to it) and/or a predetermined section of
- integrated marker means an inherent identification feature embossed on the disposable item.
- the single-use article can have a section with a magnetized structure, in particular a magnetized or magnetizable plastic, as an identification feature.
- a magnetized structure in particular a magnetized or magnetizable plastic
- identification feature can also provide information for identification.
- magnetizable or magnetized particles can be added to a plastic during production, which is used as material in the partial area of the single-use article, preferably the entire single-use article.
- the magnetization can preferably be used for a special alignment of the single-use article, since for example a special spatial position or alignment of the magnetization for an orientation can be impressed on the single-use article. Since a (permanent) magnetic field has a static orientation, this orientation can be used for the position information.
- a single magnet can also be inserted into the disposable article, which forms the marker and provides the magnetic identification feature.
- the identification feature is magnetic information, in particular as magnetized plastic, with preferably different magnetizations (alignments and/or strengths) for different disposable items such as different hoses or different slide clamps.
- a magnet is incorporated into the slide clamp.
- the magnetic information of the identification feature can be used to detect the presence of the disposable item, in particular a slide clamp, or to detect a (relative) position of the disposable item, in particular the slide clamp, based on different magnetizations and to assess it accordingly.
- a "different magnetization” means in particular a different strength of the magnetization and/or a different spatial position of the magnetization and/or a different strength of the magnetization on different sections of the single-use article.
- a magnet can preferably be introduced into the disposable article in order to detect the presence of a connection and/or a position of the connection.
- the identification feature can be a predetermined section of the disposable article with a special geometric shape or a geometric pattern.
- the introduced geometric pattern is designed in particular in the form of depressions / grooves / recesses with a special arrangement to each other.
- correct alignment of the single-use article can be ensured via the geometry and further information can be introduced for detection.
- indentations/grooves extending in the axial direction can be made on the circumference of an infusion tube in order to mark it as an original product and to make imitation more difficult.
- the geometric shapes can be used to identify the disposable item.
- An expression of the identification feature can therefore be a predefined geometry, in particular in the form of indentations/grooves/recesses in hose clamps as disposable items.
- a predetermined section of the disposable item can be provided with a color, for example red, blue, yellow or green, and the visible color can enable the disposable item to be identified.
- classes of special single-use items such as tubing can be marked, such as infusion tubing for UV-sensitive medication with the color blue, in order to enable the tubing or tubing classes to be identified via the color (via an assignment table).
- a color sensor for example a camera with downstream color recognition, can then determine the class via the color and make it available for filtering a drug database, for example.
- a possible expression of the identification feature is therefore a colour.
- infrared and/or ultraviolet markers are incorporated into the disposable article. IR markers and UV markers are not visible to the eye and are only detected when a specific wavelength range is excited or by an appropriate sensor.
- individual particles can be introduced into the material as UV markers and/or IR markers in the disposable article.
- the disposable item has specific absorption/reflection/or transmission spectra.
- the disposable article can preferably have a predetermined section of the disposable article with a predetermined conductivity.
- the section of an infusion tube that is usually used in an infusion pump can, for example, in the form of a cylindrical sheath as a coating or as be formed cylindrical hose section.
- an electrical conductivity can be set on the basis of the material.
- this conductivity s is at least 1 ⁇ 10 A 2 S/m, preferably 1 ⁇ 10 L 3 S/m, and/or at most 60 ⁇ 10 L 6 S/m, preferably 1 ⁇ 10 L 5 S/m.
- This property is also not visible to the human eye, so that on the one hand an invisible branding can be provided (precisely one conductivity) and on the other hand, in particular, through different surface materials with different conductivity on a special partial surface of the disposable item, for example an outer jacket of a hose end, for an identification feature can be provided.
- the disposable item can have an RFID tag as an integrated marker.
- This RFID tag is inextricably linked to the disposable item and is used, for example, for identification and for the transmission of information.
- a location detection can be carried out and a special filtering can be carried out on the basis of the location detection of the single-use item.
- a variant can therefore have a radio module or a transponder, such as an RFID tag. This can be used in particular for location detection and/or for detection/identification of the disposable item.
- the single-use article can have a hose, in particular an infusion hose, or a (medical) sliding clamp that can be attached to a hose and can pinch it off.
- the disposable item can be a hose with a sliding clamp.
- hoses can be manufactured in a unitary manner and only marked afterwards, which is advantageous for production and the manufacturing costs.
- the disposable article can preferably have a combination of a first identification feature and a second identification feature.
- the disposable article can have at least two integrated markers of different types.
- an infusion tube as a disposable item can have magnetic information (magnetic marker) as the first identification feature and as a second identification feature a color (color marker).
- the infusion tube can be aligned on the basis of the magnetic structure, such that the section with the color is arranged relative to a color sensor, and the infusion tube can then be identified via the color.
- a magnetic structure can be introduced into a slide clamp, so that the slide clamp can be aligned in the clamp module in order to optimally align the measurement site on the slide clamp with respect to the color sensor.
- a branding can be checked via the magnetization and color recognition can only be carried out in a next step if the check is successful. Alignment and/or identification can take place even better through a special combination of different identification features.
- the first identification feature (of the first brand) can bring about a first restriction of a medication selection (limit medication base), and the second identification feature, building on this, achieve a further restriction of the medication selection.
- the first identifier can identify a type of disposable item, such as parenteral nutrition tubing or UV-resistant tubing
- the second identifier can identify an even more specific restriction, such as chemotherapy patient nutritional solution or UV-resistant tubing for an infusion solution.
- An individual restriction can be made for a dedicated customer.
- the first feature e.g. a color
- the second feature e.g. an RFID tag
- the first feature can thus be used, for example, to limit the drug base (on the basis of the first feature) and a further restriction is made, for example, by the color as a second identification feature.
- the identification features can be changeable, for example by software/application, such as an RFID tag as an identification feature, whereby individual restrictions can be generated for a dedicated customer or a specific clinic.
- the disposable article can have a partial area with a predetermined magnetization and a partial area with a predetermined conductivity. The presence of the disposable item can first be detected by means of the magnetization and then a conductivity test can then be carried out in order to identify the disposable item.
- the single-use article can have at least two integrated markers of different types, with a first marker as the first identification feature being a predetermined section with magnetization and/or a geometric shape and/or a predetermined conductivity, and a second marker as the second identification feature being a predetermined section with one color to allow a medical device to perform a combined or two-stage detection.
- two different functions namely presence detection and color detection, can be combined by two different features.
- the magnetization and the conductivity are not visible to the user from the outside.
- the presence of, for example, a slide clamp in a clamp module of a medical device can be detected in particular by magnetizations or also special conductivities.
- the disposable article can preferably have a combination of an integrated marker as an IR marker and a magnetic marker.
- the single-use article can have at least two markers of different types, a first marker being a radio transponder, in particular an RFID tag, as the first identification feature, and a second marker being a predetermined section with one color as the second identification feature.
- a verification code can be stored in the RFID tag, which is only embedded in encrypted form by the manufacturer with a private key and can be verified using a public key. This means that an inspection can be carried out as an original part and only then (if positive) can color recognition be carried out.
- an RFID tag is integrated as a marker on a hose or a hose clamp.
- a drug base can also be selected using the information read from the RFID tag, and a specific quantity of drugs or even just one drug can be selected via the color.
- a color and a radio module or transponder can therefore be used as a marker and thus as an identification feature.
- the disposable article can have a portion with a predetermined geometry and a portion with a specific color.
- the geometry can in particular be designed as at least two bores or grooves of the disposable article, in particular a hose clamp, which are spaced apart from one another.
- a holding contour can be provided as a geometry for a clear alignment, and the color can then be recognized if the alignment is correct.
- the geometry can again be provided for branding and verification of authenticity.
- product branding e.g. identification as a B. Braun product
- indentations/geometric markings on a sliding clamp can be achieved by introducing indentations/geometric markings on a sliding clamp.
- the color recognition and the geometry information are used to enable color recognition via the branding only if the product branding has been successfully checked.
- the predetermined geometry of a slide clamp can be used to enable a holding contour for aligning the slide clamp in the clamp module.
