The treatment display 30 screen includes a treatment input list 38. The treatment input list 38 contains various treatment inputs 40, including but not limited to drug names, medications, and any other substance known in the art to be utilized for medical purposes, such as saline solution, vitamins, nutrients, etc. Each individual treatment input 40 included on the treatment input list 38 can be selected by the user by any means disclosed herein. In one embodiment of the present invention, the treatment display 30 screen displays the treatment input list 38 as a single column of treatment inputs 40; however, in other embodiments the treatment inputs 40 are displayed in two or more columns, rows, loops or other formats within the treatment input list 38, as appreciated by those skilled in the art.
The treatment display 30 includes a plurality of treatment display programming selections 42, which are used to customize the manner in which the treatment input list 38 is populated and displayed. One treatment display programming selection 42 is the “all” selection 44, which populates the treatment input list 38 with the complete collection of the treatment inputs 40 available. Another treatment display programming selection 42 is the “common” selection 46, which populates the treatment input list 38 with a collection of the most frequently used treatment inputs 40. Those having skill in the art will recognize that a variety of options are available to implement the functionalities of the treatment display programming selections 42. The “recent” selection 48 is yet another treatment display programming selection 42, which populates the treatment input list 38 with a collection of the treatment inputs 40 that have been used recently. The “orders” treatment programming selection 50 allows only those treatment inputs 40 that correspond to a patient's treatment orders to be included in the treatment input list 38. Finally, the protocols programming selection 52 populates the treatment library with programs which pre-select a particular drug, medication, or treatment to be administered (treatment input 40), in addition to the rate and volume that the treatment input 40 is to be administered, wherein each protocol 52 is specific to the treatment of a particular condition, such as breast cancer.
In one embodiment of the present invention, the treatment input list 38, whether displayed in its entirety or according to a treatment display programming selection 42, is alphabetized and sorted such that the treatment inputs 40 are grouped according to their first letter. After the groups of treatment inputs 40 beginning with the same letter are grouped within the treatment input list 38, a divider 54 is associated with each group of treatment inputs 40 beginning with the same letter. In one embodiment of the invention, each divider 54 is inserted into the treatment input list 38 and displayed such that dividers 54 separate successive alphabetized groups of treatment inputs 40 beginning with the same letter; e.g., a divider 54, displayed as “—D—,” separates the last treatment input 40 beginning with a “C” from the first treatment input 40 beginning with a “D.”
The treatment display 30 also includes a scroll bar 56 adjacent to the treatment input list 38, wherein actuation of the scroll bar 56 allows the user to navigate through the treatment input list 38 and, in one embodiment, select which treatment inputs 40 are displayed on the treatment display 30 screen. The scroll bar 56 includes a displacement detection area 58 which detects movement from a user wherein user input is translated into scroll bar 56 movement. The scroll bar 56 is linked to the treatment input list 38 such that actuation or movement of the scroll bar 56 causes the treatment display 30 to cycle through the treatment input list 38 in a corresponding manner, e.g., wherein the scroll bar 56 is vertically oriented, movement in an upward direction detected in the displacement detection area 58 causes the treatment input list 38 to cycle upward toward the beginning of the alphabet, and another embodiment having a horizontal scroll bar 56, movement in a rightward motion detected in the displacement detection area 58 causes the treatment input list 38 to cycle rightward toward the end of the alphabet. Control of the scroll bar 56, in one embodiment, is by touch screen, wherein the displacement detection area 58 detects tactile and spatial touch such that a user actuates the scroll bar 56 by touching and dragging their finger on the displacement detection area 58. However, those of ordinary skill in the art will appreciate that digital interface 10 can be actuated by a mouse, a stylus, or any other suitable known means. In yet another embodiment, the scroll bar 56 includes a slider 60 that moves along the displacement detection area 58 in a manner consistent with user actuation of the scroll bar 56 and indicates the position of the scroll bar 56 relative to the treatment input list 38. In addition, another embodiment includes directional buttons 62 at terminal ends of the displacement detection area 58 which advance the scroll bar 56 in a direction corresponding to the position of the directional buttons 62.
The scroll bar 56 scrolls to positions defined by letters of the alphabet, wherein each position of the alphabet corresponds with a divider 54 which is itself associated with each group of treatment inputs 40 beginning with the same letter. In this manner, when the scroll bar 56 scrolls to a divider 54 in the treatment input list 38, a subset of the treatment inputs 40 are displayed which, beginning with the associated divider 54, all begin with the same letter.
The treatment display 30 also includes an emergency activation point, or STAT 64, which can be activated in an emergency situation when a patient is crashing or going to code. Activation of the STAT 64 activation point allows the user to input the rate 80 (described below) of treatment administration without specifically selecting the treatment input 40 in order to more quickly administer life saving treatment or medication.
