Abstract
Method and system for providing analyte sensor alignment and retention mechanism for improved connectivity with a transmitter unit for electrical connection, and further including transmitter unit contact pins with metal components to improve electrical conductivity with the analyte sensor in an analyte monitoring and management system is provided.
Description
BACKGROUND

Analyte monitoring systems including continuous glucose monitoring systems generally include an analyte sensor such as a subcutaneous analyte sensor, at least a portion of which is configured for fluid contact with biological fluid, for detecting analyte levels such as for example glucose or lactate levels, a transmitter (such as for example an RF transmitter) in communication with the sensor and configured to receive the sensor signals and to transmit them to a corresponding receiver unit by for example, using RF data transmission protocol. The receiver may be operatively coupled to a glucose monitor that performs glucose related calculations and data analysis.


The transmitter may be mounted or adhered to the skin of a patient and also in signal communication with the sensor. Generally, the sensor is configured to detect the analyte of the patient over a predetermined period of time, and the transmitter is configured to transmit the detected analyte information over the predetermined period of time for further analysis. To initially deploy the sensor so that the sensor contacts and electrodes are in fluid contact with the patient's analyte fluids, a separate deployment mechanism such as a sensor inserter or introducer is used. Moreover, a separate base component or mounting unit is provided on the skin of the patient so that the transmitter unit may be mounted thereon, and also, to establish signal communication between the transmitter unit and the analyte sensor.


As discussed above, the base component or mounting unit is generally adhered to the skin of the patient using an adhesive layer that is fixedly provided on the bottom surface of the base component or the mounting unit for the transmitter. To minimize data errors in the continuous or semi-continuous monitoring system, it is important to properly insert the sensor through the patient's skin and securely retain the sensor during the time that the sensor is configured to detect analyte levels. In addition to accurate positioning of the sensor through the skin of the patient, it is important to ensure that the appropriate electrode of the analyte sensor are in continuous and proper electrical connection or communication with the corresponding contact points or pads on the transmitter unit.


Additionally, for the period of continuous or semi-continuous monitoring which can include, for example, 3 days, 5 days or 7 days, it is important to have the transmitter unit securely mounted to the patient, and more importantly, in proper contact with the analyte sensor so as to minimize the potential errors in the monitored data.


In view of the foregoing, it would be desirable to have an approach to provide methods and system for accurate and simple ways in which to securely couple the analyte sensor with the transmitter unit so as to maintain continuous electrical connection therebetween. Moreover, it would be desirable to have methods and system for easy deployment of sensors and subsequent simple removal of the same in a time effective and straight forward manner.

In accordance with the various embodiment of the present invention, there is provided method and system for providing analyte sensor alignment and retention mechanism for improved connectivity with a transmitter unit for electrical connection, and further including transmitter unit contact pins with metal components to improve electrical conductivity with the analyte sensor in an analyte monitoring and management system.

DETAILED DESCRIPTION


FIG. 1 illustrates a data monitoring and management system such as, for example, an analyte monitoring and management system 100 in accordance with one embodiment of the present invention. In such embodiment, the glucose monitoring system 100 includes a sensor 101, a transmitter 102 coupled to the sensor 101, and a receiver 104 which is configured to communicate with the transmitter 102 via a communication link 103. The receiver 104 may be further configured to transmit data to a data processing terminal 105 for evaluating the data received by the receiver 104. In addition, as shown in the Figure, a medication delivery unit 106 maybe provided and operatively coupled to the receiver unit 104 and configured to receive one or more of data or commands directed to the control of the medical delivery unit 106 for delivering medication to a patient such as insulin.


Only one sensor 101, transmitter 102, communication link 103, receiver 104, data processing terminal 105, and medication delivery unit 106 are shown in the embodiment of the analyte monitoring and management system 100 illustrated in FIG. 1. However, it will be appreciated by one of ordinary skill in the art that the glucose monitoring system 100 may include one or more sensor 101, transmitter 102, communication link 103, receiver 104, and data processing terminal 105, where each receiver 104 is uniquely synchronized with a respective transmitter 102 to deliver medication through the medication delivery unit 106 such as an infusion pump. Moreover, within the scope of the present invention, the analyte monitoring and management system 100 may be a continuous monitoring and management system, or a semi-continuous or discrete monitoring and management system.


In one embodiment of the present invention, the sensor 101 is physically positioned on the body of a user whose glucose level is being monitored. The sensor 101 may be configured to continuously sample the glucose level of the user and convert the sampled analyte level into a corresponding data signal for transmission by the transmitter 102. In one embodiment, the transmitter 102 is mounted on the sensor 101 so that both devices are positioned on the user's body. The transmitter 102 performs data processing such as filtering and encoding on data signals, each of which corresponds to a sampled analyte level of the user, for transmission to the receiver 104 via the communication link 103.


In one embodiment, the analyte monitoring and management system 100 is configured as a one-way RF communication path from the transmitter 102 to the receiver 104. In such embodiment, the transmitter 102 transmits the sampled data signals received from the sensor 101 without acknowledgement from the receiver 104 that the transmitted sampled data signals have been received. For example, the transmitter 102 may be configured to transmit the encoded sampled data signals at a fixed rate (e.g., at one minute intervals) after the completion of the initial power on procedure. Likewise, the receiver 104 may be configured to detect such transmitted encoded sampled data signals at predetermined time intervals. Alternatively, the analyte monitoring and management system 100 may be configured with a bi-directional RF communication between the transmitter 102 and the receiver 104.


Additionally, in one aspect, the receiver 104 may include two sections. The first section is an analog interface section that is configured to communicate with the transmitter 102 via the communication link 103. In one embodiment, the analog interface section may include an RF receiver and an antenna for receiving and amplifying the data signals from the transmitter 102, which are thereafter, demodulated with a local oscillator and filtered through a band-pass filter. The second section of the receiver 104 is a data processing section which is configured to process the data signals received from the transmitter 102 such as by performing data decoding, error detection and correction, data clock generation, and data bit recovery.


In operation, upon completing the power-on procedure, the receiver 104 is configured to detect the presence of the transmitter 102 within its range based on, for example, the strength of the detected data signals received from the transmitter 102 or a predetermined transmitter identification information. Upon successful synchronization with the corresponding transmitter 102, the receiver 104 is configured to begin receiving from the transmitter 102 data signals corresponding to the user's detected glucose level. More specifically, the receiver 104 in one embodiment is configured to perform synchronized time hopping with the corresponding synchronized transmitter 102 via the communication link 103 to obtain the user's detected analyte level.


Referring again to FIG. 1, the data processing terminal 105 may include a desktop computer terminal, a data communication enabled kiosk, a laptop computer, a handheld computing device such as a personal digital assistant (PDAs), or a data communication enabled mobile telephone, and the like, each of which may be configured for data communication with the receiver via a wired or a wireless connection. Additionally, the data processing terminal 105 may further be connected to a data network (not shown) for storing, retrieving and updating data corresponding to the detected glucose level of the user. In addition, the data processing terminal 105 in one embodiment may include physician's terminal and/or a bedside terminal in a hospital environment, for example.


Moreover, the medication delivery unit 106 may include an infusion device such as an insulin infusion pump, which may be configured to administer insulin to patients, and which is configured to communicate with the receiver unit 104 for receiving, among others, the measured analyte level. Alternatively, the receiver unit 104 may be configured to integrate an infusion device therein so that the receiver unit 104 is configured to administer insulin therapy to patients, for example, for administering and modifying basal profiles, as well as for determining appropriate boluses for administration based on, among others, the detected glucose levels received from the transmitter 102. Referring again to FIG. 1, the medication delivery unit 106 may include, but not limited to an external infusion device such as an external insulin infusion pump, an implantable pump, a pen-type insulin injector device, a patch pump, an inhalable infusion device for nasal insulin delivery, or any other type of suitable delivery system.


Each of the transmitter unit 102, the receiver unit 104, the data processing unit 105, and the medication delivery unit 106 maybe configured to communicate with each other over a wireless data communication link similar to the communication link 103 such as, but not limited to RF communication link, Bluetooth communication link, infrared communication link, or any other type of suitable wireless communication connection between two or more electronic devices. The data communication link may also include wired cable connection such as, for example, but not limited to RS232 connection, USB connection, or serial cable connection.


Moreover, referring to FIG. 1, the analyte sensor unit 101 may include, but not limited to short term subcutaneous analyte sensors or transdermal analyte sensors, for example, which are configured to detect analyte levels of a patient over a predetermined time period.


Additional analytes that may be monitored, determined or detected by the analyte sensor unit 101 include, for example, acetyl choline, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase (e.g., CK-MB), creatine, DNA, fructosamine, glucose, glutamine, growth hormones, hormones, ketones, lactate, peroxide, prostate-specific antigen, prothrombin, RNA, thyroid stimulating hormone, and troponin.
