The Merative US LP invention works as follows
A tracking codes is adhered to the syringe labels cradle in order to track each activity relating to the syringe labels cradle. For example, drug preparation and inventory, dispensing of drugs, administration of drugs, drug returns, charges for drugs, etc. The tracking code can be in bar code or another machine-readable code as well as in human-readable indicia. The tracking code allows for the tracking of events that pertain to a particular syringe, from its preparation with a prescription drug until it is disposed of or returned to a pharmacy. The log relates the patient with the drug and any information entered in relation to the tracking code.
Background for Drug Delivery Device incorporating a Tracking Code
The present invention is a general drug delivery system and, more specifically, a unique tracking codes associated with a device used to deliver drugs to patients. This code allows the physician to create and retrieve a log of data relating to the patient, the drug, and the device.
In hospitals and other surgical centers, the manual dispensing of medications from a pharmacy to administer to a patient has become a standard practice. The pharmacy department fills syringes of drugs and administers them to patients. Documentation is done retrospectively by physicians or other health professionals. Drug diversion, medication mistakes, errors of admissions, medication contamination, and accidental needle sticks are all possible due to human error. Emergency situations can also make the process more difficult, as they require a quick setup and administration, and less time for accurate and timely record keeping. There is no record of a syringe’s history from the moment it was filled until the time that the sterile syringe is disposed of or returned to the pharmacy.
Walker, et al., U.S. Pat. No. The present application is based on U.S. Patent No. 5,651,775, which was assigned to the same assignee as the patent in question. This patent, which has been incorporated by reference herein, discloses a system for monitoring and delivering drugs to patients. Drugs are delivered safely to a patient and monitored live during the delivery. Important events during the delivery are also recorded to provide online information and details to an audit trail. The drug delivery and monitor system includes a scanning module as well as a syringe-label cradle and cassette tray. The syringe cradle acts as both a holder for a drug-containing syringe and a positioner. The syringe cradle can be constructed in multiple sizes to accommodate different syringe sizes. This allows for a constant needle position of the combined unit regardless of syringe volume. The syringe will be positioned in the cradle, and then a pre-printed label with self adhesive is attached to it. The label contains drug identification information and preparation information, such as dosage and concentration. This can be displayed in a form that is machine-readable or human-readable such as a bar code. The label information is read automatically into the system using an optical barcode scanning module, for example.
A number of syringe-label cradle unit, that is, combination syringe-label cradle with syringe are placed in a cassette tray to be transported and stored before, during, and after use. The cassette tray is generally organized so that the syringe labels cradles are arranged in a logically advancing order. The cassette tray aligns with the injection port, which is usually connected to the needleless IV set. The scanning module includes bar code scanners or other digital indicators to read labels attached to the syringe cradle. The information on the label takes the form of a code that identifies, for example the drug in the associated syringe. It also identifies the size of the associated syringe. The scanning module is also used to monitor syringe movement while the drug is administered. This allows for real-time drug administration dynamics, such as determining the delivery rate and quantity of administered drugs.
The need for improved drug administration systems that provide a variety medical devices (e.g. preloaded syringes, IV ports) with machine-readable and/or readable information is a necessity. This will allow accurate tracking of events in the history of a medical device.
The tracking code system described herein can be used to track a wide range of medical devices and applications, including but not limited injected drugs. The term “medical device” is used in a broad sense. As used herein, the term “medical device” includes any syringe applications, IV ports or drug vials and ampules as well as non-injectable fluids. The present invention is a tracking system that uses a code to identify a syringe label unit or a port label unit, as will be described in more detail below.
As discussed in Walker et. al., a syringe-label cradle is a product that can only be used once and is designed to hold a specific syringe, both by manufacturer and size. SLCs have been designed to fit standard syringe sizes. SLCs and syringes that form a syringe label unit, which is a combination of the two, are encoded with patient-specific tracking codes. As an example, the patient-specific tracking code can be encoded as a barcode that is machine-readable. The bar coded SLC includes a unique numeric area of 22 characters, for instance. Encoding is done in the pharmacy, or another designated area for preparation. A bar code label will be mounted on the SLC’s flange. The SLCs are then matched to the standard syringes and placed in administration order in a cassette tray. The encoded SLC allows for accurate tracking and drug delivery data.
The bar code tracking code is generated by computer using a time stamp, drug identification data and a time stamp. The tracking code will be associated with each activity that the SLC performs. This includes drug preparation, inventory, dispensing of drugs, administration of drugs, return or credit for drugs, etc. The tracking code allows for the tracking of events related to a specific syringe, or other medical devices such as an IV attached to a person. Every time an SLC delivers a drug, a log containing all the information in the patient and drug databases is created. The tracking code allows specific drug usage to be tracked. This is useful for FDA drug recalls, narcotics control and drug research – both important areas in pharmacy practice. Narcotic control is required by federal and state laws. The host database server retrieves detailed information about the medication to be administered. This includes the name, concentration and expiration date/time of the medication, as well as the technician who will administer it. The information can be stored on the server or a remote server (i.e. Ethernet/network implementation).
