ELECTRONIC INJECTOR FOR INJECTING A MEDICINAL PRODUCT
An example injector includes a rotary knob for selecting a function and setting a dosing quantity for an injection, a button located on an end of the rotary knob for initiating the injection, an electric motor, an encoder for evaluating output rotary motion of the motor, and a processor that converts the dosing quantity into a number of encoder pulses and controls operation of the motor based on the number of encoder pulses when dosage is triggered. The injector also includes a transmission coupled to the electric motor to convert a speed of the motor, a threaded spindle coupled to the transmission that moves linearly based on the output rotary motion of the motor at the speed as converted by the transmission, and a punch connected to an end of the threaded spindle. The linear movement of the spindle causes the punch to release medicament.
1 . An injector comprising:
a motor, whereby rotation of the motor causes a medicinal product to be expelled; and
a button, which is pressed to initiate and maintain an injection of the medicinal product, whereby pressure applied to the button during the injection changes a speed of the motor and as such a speed of the injection.
2 . The injector of claim 1 , wherein a continuous press of the button is required to maintain the injection until completion of a dosage.
3 . The injector of claim 2 , wherein an interruption of the continuous press causes the injection to pause.
4 . The injector of claim 2 , wherein the button further comprises a touch-sensitive surface operable to receive an input based on a touch-contact.
5 . The injector of claim 2 , wherein the button further comprises a fingerprint sensor for an authentication for use of the injector.
6 . The injector of claim 2 , wherein the button further comprises a proximity sensor for detection of an object in proximity to the button.
7 . The injector of claim 1 , wherein the injector is configured to be alternatively operated in a binary press mode, in which the button, when pressed a first time, initiates the injection, and when pressed a second subsequent time, stops the injection.
8 . The injector of claim 1 , further comprising:
a light ring positioned circumferential to the button, wherein the light ring is illuminated in a sequence of illumination to inform of a status of the injection.
9 . A method for operating an injector, comprising:
receiving an input for initiating a medicinal product to be expelled from the injector based on actuation of a button of the injector;
based on detection of a continuous actuation of the button, maintaining administering of the medicinal product;
based on detection of an interruption of the continuous actuation of the button, pausing administering of the medicinal product; and
controlling a speed of a motor of the injector and as such a speed of injection based on a pressure applied to the button.
10 . An injector, comprising:
a tactile dose-setting field for receiving a sliding contact input to set a dosing quantity for an injection, wherein the tactile dose-setting field includes a display area for indicating the dosing quantity with graphical indicators; and
a dose indicator display coupled to the tactile dose-setting field for displaying the dosing quantity based on the sliding contact input.
11 . The injector of claim 10 , further comprising:
a tactile component coupled to the tactile dose-setting field for providing force, motion, or vibration feedback based on receipt of the sliding contact at the tactile dose-setting field.
12 . The injector of claim 10 , wherein the tactile dose-setting field is configured to receive the sliding contact input in a linear motion along a first direction and a second direction, wherein the second direction is opposite the first direction.
13 . The injector of claim 12 , wherein receipt of the sliding contact input in the first direction increases the dosing quantity and receipt of the sliding contact input in the second direction decreases the dosing quantity.
14 . The injector of claim 10 , wherein the tactile dose-setting field and the dose indicator display are positioned on a side of the injector, and the injector further comprising:
a light ring positioned on an end of the injector, wherein the light ring is illuminated in a sequence of illumination to inform of a status of the injection.
15 . The injector of claim 10 , wherein the tactile dose-setting field and the dose indicator display are positioned on a side of the injector, and the injector further comprising:
a button positioned on an end of the injector, wherein the button is configured to be actuated to initiate an injection of the medicinal product.
16 . The injector of claim 15 , wherein the button further comprises a touch-sensitive surface operable to receive an input based on a touch-contact.
17 . The injector of claim 15 , further comprising:
a light ring positioned circumferential to the button, wherein the light ring is illuminated in a sequence of illumination to inform of a status of the injection.
18 . A method for operating an injector, comprising:
receiving, via a tactile dose-setting field, a sliding contact input to set a dosing quantity for an injection, wherein the tactile dose-setting field includes a display area for indicating the dosing quantity with graphical indicators; and
displaying, via a dose indicator display coupled to the tactile dose-setting field, the dosing quantity based on the sliding contact input.
19 . The method of claim 18 , wherein the tactile dose-setting field and the dose indicator display are positioned on a side of the injector, and the method further comprises:
illuminating a light ring, which is positioned on an end of the injector, in a sequence of illumination to inform of a status of the injection.
20 . The method of claim 18 , wherein the tactile dose-setting field and the dose indicator display are positioned on a side of the injector, and the method further comprises:
receiving, via actuation of a button positioned on an end of the injector, a signal to initiate an injection of a medicinal product.
