Abstract

A syringe pump has a radio-frequency reader (40) arranged to read a radio-frequency coded marker (31) on the syringe (3) containing information about the nature of the infusate, intended patient, prescriber and the like. The information read by the reader is used to control operation of the pump. The reader (40) is also able to read RF coded markers on a patient identification (labe150) and on a care giver identification labe (160).

Description

INFUSION APPARATUS COMPRISING RADIO-FREQUENCY READABLE CODED MARKERS

This apparatus relates to infusion apparatus of the kind including an infusion reservoir, a marker associated with the infusion reservoir and a reader associated with the apparatus by which the marker associated with the reservoir can be read.

In order to reduce the risk of incorrect administration of medication to patients it has been proposed that medication reservoirs such as pre-filled syringes and infusion bags or the like be marked with machine-readable markings that can be read by the infusion device. The machine-readable markings are most conveniently printed bar codes. Conventional bar codes comprise a row of vertical lines and spaces of varying widths, which are read by scanning along the row. These bar codes enable about twenty- five characters to be represented in a convenient length. This enables the medication reservoir to be given a unique serial number by the pharmacy, which can be stored in the infusion apparatus. If the infusion apparatus and the pharmacy are linked by a common database system, the infusion apparatus can use the serial number to obtain information about the medication and how it is intended to be used so that this information can be used by the apparatus. Where the infusion apparatus is not linked into a common database, however, the nature of the bar code limits the amount of information that can be provided and hence restricts the functions of the infusion apparatus that can be controlled.

It is an object of the present invention to provide alternative infusion apparatus and methods.

According to one aspect of the present invention there is provided infusion apparatus of the above-specified kind, characterised in that the marker is a radio-frequency readable coded marker and that the reader is a radio-frequency reader operable to read the coded marker such that information contained therein is utilized by the apparatus.

The information contained in the radio-frequency coded marker is preferably selected from a list comprising: information about the nature of infusate in the reservoir; batch number; expiry date; date of intended use; time of intended use; name of intended patient; weight of intended patient; body surface area of intended patient; name of prescriber; name of consultant; allergies of intended patient; restricted drugs of intended patient; name of nurse; priority level of nurse; and information about infusion apparatus on which the nurse has trained. The information contained in the radio-frequency coded marker preferably includes a plurality of items of information selected from the list. Infusate contained in the reservoir may be a medicine. The infusion apparatus may be an infusion pump. The pump preferably includes a housing supporting the infusion reservoir, a pumping mechanism and a processor within the housing, the reader being connected directly with the housing.

According to another aspect of the present invention there is provided a system including infusion apparatus according to the above one aspect of the present invention and a patient identification label carrying a radio-frequency coded marker thereon containing information about the patient, the reader being adapted also to read the marker on the patient identification label.

According to a further aspect of the present invention there is provided a system including infusion apparatus according to the above one aspect of the present invention and a care giver identification label carrying a radio-frequency coded marker thereon containing information about the care giver, the reader being adapted also to read the marker on the care giver identification label.

According to a fourth aspect of the present invention there is provided an infusion reservoir having a radio-frequency coded marker thereon for use in apparatus or in a system according to the above aspects of the present invention, the radio-frequency coded marker on the reservoir including data about fluid within the reservoir.

According to a fifth aspect of the present invention there is provided a method of infusing fluid to a patient including the steps of providing the fluid in a reservoir having a radio-frequency coded marker associated therewith, reading the marker with a reader and supplying information from the reader to infusion apparatus to control operation of the apparatus. The method may include the step of using the reader to read a radio-frequency coded marker on a patient identification label and or alternatively using it to read a radio-frequency coded marker on a care giver identification label.

According to a sixth aspect of the present invention there is provided a method of infusing fluid to a patient including the steps of providing a radio-frequency coded marker containing data about the fluid to be infused in association with a fluid reservoir, reading the marker with a radio frequency reader and supplying information from the reader to infusion apparatus to control operation of the apparatus.

A syringe pump and its method of operation according to the present invention, will now be described, by way of example, with reference to the accompanying drawing, which is a simplified elevation view of the pump and a syringe containing medication.

The pump is conventional in many respects and may be of the kind described in EP1186311 and EP1188454, comprising a housing 1 with a recess 2 on one surface adapted to receive a syringe 3. A drive mechanism 4 within the housing 1 is controlled by a processor 5 to displace a plunger pusher mechanism 6, which engages and pushes the plunger 7 of the syringe 3 into the barrel 8 to dispense fluid medication in the syringe to a catheter 9 connected to its nose 10. It will be appreciated that the pump includes various conventional control and safety features well known to those in this field.

The syringe 3 has an RFID tag or other radio-frequency readable coded marker 30 adhered to it and encoded with data by the hospital pharmacy. Alternatively, the tag could be associated with the syringe in other ways such as being carried on packaging or the like for the syringe or built into the body of the syringe. The RFID tag could be of the active or passive type.

The pump includes a RFID reader 40 of conventional construction connected with the pump processor via a cable 41 and connector 42. Alternatively, the reader could be connected with the pump by a wireless connection, such as an infra-red or radio frequency connection, or the reader could be built into the pump housing 1. It is not essential that the reader be connected directly with the pump since it could be connected with an ancillary computer (not shown) interconnected with the pump in some way. The reader 40 is adapted to read the RFID tag 30 code associated with the syringe 3 and to transfer the data in that code to the pump so that the operation of the pump is controlled in some way by the transferred data.

RFID tags are available in forms that can contain data comprising anything between single bits and kilobits. Typically a tag would be selected capable of storing about 250 characters or more, which enables the following information to be contained within the code:

- drug name, concentration and dose

- buffer name, concentration and dose

- batch number

- expiry date

- date and time of intended use

- name of patient for which the medication is intended, with his weight and body surface area

- details of any allergies or restricted drugs of the patient

- name of the prescriber

- name of the consultant

- name of the nurse intended to give the medication

- priority level of the nurse

- list of the pumps on which the nurse has been trained

It will be appreciated that the tag 30 need not contain all this data and could contain other data.

The information in the tag 30 is sufficient to enable the processor 5 in the pump to set up a suitable infusion protocol for the intended patient. The reader 40 can also be used to read an RFID tag 51 on a patient's name band or other label 50 and an RFID tag 61 on the name badge 60 of the nurse or other care giver to confirm that the medication is being given to the correct patient and by the appropriate nurse.

This system can enable medication errors to be reduced by reducing the risk that inappropriate doses are administered. Although previous systems employing bar codes have enabled the pump to check the serial number of the medication, it has only been possible for the pump to obtain further information about the specific medication and its intended use if the pump is connected to the hospital's computer system. The present invention, by contrast, enables considerable information to be provided to the pump even when the hospital does not have a compatible computer system, or when the pump is used out of a hospital environment.

It will be appreciated that the invention is not confined to syringe pumps but could be used with other infusion apparatus such as volumetric pumps or gravity infusors. The invention is not confined to use with medication but could be used with other infusion fluids, such as saline, feeding fluids, blood or the like.
