Multi-layer system for the irreversible deactivation of anesthetic drug residues in a case-specific disposal container

Abstract

(Main claim) Disposal container for the irreversible deactivation of anesthetic drug residues, comprising a multi-layered binding system arranged from top to bottom and including: 1. an upper layer of adsorbent and / or ion exchange resin, 2. a middle layer of activated carbon or another adsorption matrix, 3. a lower layer of a polymer gel for solidifying residual liquids, the layers are designed in such a way that propofol, opioids and ketamine are bound and solidified sequentially, and recovery of the active ingredients is impossible.

Description

Technical field

[0001] The invention relates to the safe disposal of residual quantities of liquid anesthetic drugs in clinical working environments, particularly in anesthesia.

[0002] It includes a disposal container with a multi-layered binding system for the irreversible deactivation of propofol, opioids, ketamine, and other drugs. Initial situation and problem statement

[0003] In clinical anesthesia, residual amounts of the following substances are generated after almost every procedure: • Propofol (lipophilic emulsion, risk of abuse, environmentally harmful) • Opioids (controlled substances, risk of abuse) • Ketamine (risk of abuse) • Benzodiazepines • Etomidate

[0004] Currently, no systems exist that: • Safely deactivate propofol, opioids, and ketamine simultaneously • ensure irreversible bonding, • can be used on a case-by-case basis in the operating room workflow, • and integrate a controlled substances documentation interface. Object of the invention

[0005] The object of the invention is to provide a system that: • Irreversibly binds residual amounts of typical anesthetic drugs, • can be used in a case-specific and workflow-compatible manner, • enables safe one-handed disposal, • and allows for unambiguous documentation assignment. Solution to the task

[0006] The task is solved by a waste container with a multi-layered binding agent system, which is structured from top to bottom as follows: (1) Top layer: Adsorber / ion exchange resin • Primary contact with incoming liquid • Binding of basic active substances (opioids, ketamine) • Adsorption of lipophilic components • High permeability to subsequent liquid (2) Middle layer: Activated carbon / Adsorption matrix • Adsorption of lipophilic substances, especially propofol • Buffer zone for additional drug binding (3) Lower layer: Polymer gel / solidifier • Absorption and solidification of residual liquid • End barrier against leakage • Ensuring irreversibility

[0007] The container also includes: • a filling opening with backflow preventer, • a case-related documentation interface (QR code, RFID, serial number), • a fill level indicator, • and an end lock after saturation. Advantages of the invention • Simultaneous deactivation of propofol, opioids and ketamine • Irreversible bonding through a combination of adsorption, ion exchange, and solidification • No recovery of the active ingredients • Case-related assignment in the controlled substances workflow • One-handed operation in the operating room setting • Minimizing microbial risks • Safe disposal without additional equipment

Claims

(Main claim) Disposal container for the irreversible deactivation of anesthetic drug residues, comprising a multi-layer binding system arranged from top to bottom and comprising:

1. an upper layer of adsorbent and / or ion exchange resin, 2. a middle layer of activated carbon or another adsorption matrix, 3. a lower layer of a polymer gel for solidifying residual liquids, wherein the layers are designed such that propofol, opioids and ketamine are sequentially bound and solidified and recovery of the active substances is excluded.
