The present disclosure relates generally to medication delivery to patients and, in some non-limiting embodiments or aspects, to a sensory assembly for monitoring push medication delivery to patients from syringes.
Barcoded Medication Administration (BCMA) is an inventory control system that uses barcodes to reduce or prevent human errors in the distribution of prescription medications at hospitals. A goal of BCMA is to make sure that patients are receiving the correct medications at the correct time by electronically validating and documenting medications. The information encoded in barcodes allows for the comparison of the medication being administered with what was ordered for the patient.
Currently, BCMA is the only safety check performed near the patient to reduce or prevent misadministration of medications and aid in documentation in the electronic medical record/electronic health record (EMR/EHR). Accordingly, there is a monitoring gap for drugs delivered via syringe in that an act of connection to a patient's IV line/catheter and dispensing or delivery of a drug may not be monitored.
Accordingly, provided are improved systems, devices, products, apparatus, and/or methods for monitoring push medication delivery to patients from syringes.

In some non-limiting embodiments or aspects, identifier element 118 of syringe 102b may be used by processor 146 of sensor assembly 104 (and/or computing device 106) to estimate a position of stopper 116 and/or plunger rod 114 of syringe 102b. For example, image processing software may record an initial position of stopper 116 and/or plunger rod 114 of syringe 102b relative to the position of identifier element 118 and, when stopper 116 and/or plunger rod 114 of syringe 102b moves relative to the position of identifier element 118, the image processing software may determine that a medication delivery procedure has begun. When stopper 116 and/or plunger rod 114 of syringe 102b advances a predetermined distance from identifier element 118, it may be assumed that the fluid delivery procedure is complete.
In some non-limiting embodiments or aspects, processor 146 of sensor assembly 104 (and/or computing device 106) may automatically identify the position of stopper 116 and/or plunger rod 114 of syringe 102b relative to other markers on syringe 102b. For example, the markings may be graduated lines and/or indicia on syringe barrel 112. As an example, the movement of stopper 116 and/or plunger rod 114 of syringe 102b relative to the markings may be used determine not only initiation and dose, but also fluid volume delivered.
In some non-limiting embodiments or aspects, processor 146 of sensor assembly 104 (and/or remote computing device 106) may determine, in response to detecting, in the one or more images, a backward or proximal movement of the stopper and/or the plunger rod of the syringe that satisfies a threshold distance, a positive lumen patency. For example, a flush syringe may be used to check catheter patency by aspirating (e.g., pulling back, etc.) on the plunger of the syringe, and if processor 146 of sensor assembly 104 (and/or remote computing device 106) determines that the plunger of the syringe has moved in a backward direction a distance that satisfies the threshold distance, processor 146 of sensor assembly 104 (and/or remote computing device 106) may confirm the positive catheter patency and/or provide an indication of the positive catheter patency to the user (E.g., via user feedback device 150, etc.). In some non-limiting embodiments or aspects, processor 146 of sensor assembly 104 (and/or remote computing device 106) may additionally, or alternatively, confirm the positive lumen patency in response to detecting, in the one or more images (e.g., using the image processing software, etc.), blood in the lumen (e.g., in the catheter line, etc.).

In some non-limiting embodiments or aspects, processor 146 of sensor assembly 104 (and/or computing device 106) may control user feedback device 150 to provide guidance on rate of administration or delivery of the medication (e.g., fast, slow, “over X minutes”, etc.). As an example, processor 146 of sensor assembly 104 (and/or computing device 106) may compare, during the fluid delivery procedure a current delivery rate to a prescribed or approved delivery rate for the medication and, based on the comparison, provide guidance to maintain the delivery rate, increase the delivery rate, and/or reduce the delivery rate. For example, during medication delivery, the current rate of delivery of the medication may be variable over a delivery time period, and processor 146 of sensor assembly 104 (and/or computing device 106) may compare the current rate of delivery to the prescribed rate or an ideal steady rate and determine whether the current rate of delivery should be increased, decreased, or maintained to match the prescribed or ideal rate of delivery (and/or control user feedback device 150 to provide a prompt to the user to increase, decrease, or maintain the current rate of delivery to match the prescribed or ideal rate of delivery). As an example, some users may attempt to maintain a steady rate of delivery over a delivery time period (e.g., 1 minute, etc.); however, other users may deliver ¼th a dose rapidly 4 separate times over the delivery time period, which may be a less ideal delivery from a pharmacokinetics perspective than the more steady rate of delivery over the delivery time period. In this way, non-limiting embodiment or aspects of the present disclosure may improve a steadiness of medication delivery.

Although embodiments or aspects have been described in detail for the purpose of illustration and description, it is to be understood that such detail is solely for that purpose and that embodiments or aspects are not limited to the disclosed embodiments or aspects, but, on the contrary, are intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present disclosure contemplates that, to the extent possible, one or more features of any embodiment or aspect can be combined with one or more features of any other embodiment or aspect. In fact, any of these features can be combined in ways not specifically recited in the claims and/or disclosed in the specification. Although each dependent claim listed below may directly depend on only one claim, the disclosure of possible implementations includes each dependent claim in combination with every other claim in the claim set.
The present application claims priority to U.S. Provisional Application No. 63/439,689 entitled “Sensor Assembly and System for Monitoring Push Medication Delivery to Patients from Syringes” filed Jan. 18, 2023, the entire disclosure of which is hereby incorporated by reference in its entirety.
