PORTABLE INFUSION PUMP WITH REMOTE ACTIVATOR

Abstract

A system for activating a portable infusion pump includes a remote interaction device operated by the user for direct communication with the pump. Upon receipt of an initiate signal from the user, a computer on-board the infusion pump evaluates status metrics from the infusion pump, along with clinical information, to validate the initiate signal. With this validation, the computer identifies an appropriate response for operating the infusion pump. An indicator on the infusion pump then informs the user of the appropriate response for the user to follow for activating the infusion pump.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The novel features of this invention, as well as the invention itself, both as to its structure and its operation, will be best understood from the accompanying drawings, taken in conjunction with the accompanying description, in which similar reference characters refer to similar parts, and in which:

[0014] FIG. 1 is a schematic presentation of operational components for the present invention; and

[0015] FIG. 2 is a functional flow sequence of the interactive steps involved in an operation of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Referring initially to FIG. 1 a system for infusing a fluid (liquid) medicament to a user is shown and is generally designated 10. As shown, the system 10 includes an interactive device 12 that is directly operated by the user (not shown). FIG. 1 also shows an infusion pump 14 is included in the system 10, and that the infusion pump 14 will normally be automatically operated in accordance with a pre-programmed protocol 16. As envisioned for the present invention, the protocol 16 will typically follow a specified operational regimen for an infusion therapy, and it will typically be prescribed by a physician.

[0017] With reference to FIG. 1, it is to be appreciated that the infusion pump 14 includes a pumping mechanism 18 which is under the control of a computer 20. As a component of the system 10, the computer 20 is physically mounted on the infusion pump 14. FIG. 1 also shows that the computer 20 has an interactive connection with status metrics 22 that are pertinent to the operation of the infusion pump 14. Specifically, the status metrics 22 will typically include information on the operational condition of the infusion pump 14, as well as parameters for compliance with the protocol 16. FIG. 1 further shows that communication between the computer 20 and the interactive device 12 is provided via a two-way communications link 24. Preferably, the two-way communications link 24 is voice activated, although other modes of communications, such as a “texting” operation, are possible for an operation of the present invention.

[0018] The sole function of the interactive device 12 is to initiate an activation of the infusion pump 14. As shown in FIG. 2, this initiation is accomplished by sending an initiate message 26 from the user to the computer 20. The initiate message 26 does not however, by itself, activate the infusion pump 14. Instead, the initiate message 26 expresses the intentions of the user and it will typically include both temporal and quantitative information for a desired operation of the infusion pump 14. Importantly, although the time, duration and quantity of an infusion may be changed by the initiate message 26, the present invention requires the initiate message 26 be checked and verified before the infusion pump 14 is activated.

[0019] In FIG. 2 it is seen that when an initiate message 26 is sent to the computer 20, it is immediately checked and verified by an evaluate/validate function 28 of the computer 20. In detail, the evaluate aspect of function 28 is accomplished, in part, with reference to the status metrics 22 that have been compiled by the computer 20. This evaluation of the status metrics 22 is also based on reference to the protocol 16 via its connection with the computer 20 as shown in FIG. 1. The validate aspect of the function 28 is thus accomplished based on both operational and clinical information, with consideration given to the user's intentions expressed in the initiate message 26. Moreover, the validate aspect of the function 28 creates an indicating signal 30 that appears on an indicator 31 which is mounted on the infusion pump 14, as shown in FIG. 1. Specifically, the indicator 31 presents a response option 32 that may either support or reject the intentions presented in the initiate message 26.

[0020] Once the initiate message 26 has been evaluated and validated the indicating signal 30 can be created on the indicator 31 in any of several modes. For instance, the indicating signal 30 may be audible tones, vibrations, lights, or a combination thereof.

[0021] The response option 32 provided by the indicating signal 30 will typically include a choice between several courses of action for the user; see block 34 of FIG. 2. These options include: i) activating an operation 36 of the infusion pump 14 in accordance with the initiate message 26, ii) revising the initiate message 26 for compliance purposes, and iii) accepting a default with no further action. As indicated above, the particular response option 32 which is selected by the user can be manifested either verbally using the interactive device 12, or tactilely. When a tactile response is to be made, a response button (not shown) on the infusion pump 14 may be used. As envisioned for the present invention, this can be either a capacitive button, an accelerometer to register taps and shakes, or a biometric reader.

[0022] While the particular Portable Infusion Pump with Remote Activator as herein shown and disclosed in detail is fully capable of obtaining the objects and providing the advantages herein before stated, it is to be understood that it is merely illustrative of the presently preferred embodiments of the invention and that no limitations are intended to the details of construction or design herein shown other than as described in the appended claims.
