Ostomy base plate with sensor assembly for monitoring adhesive layer
A recently filed patent (Publication Number: US20230310201A1) describes an innovative ostomy base plate that includes a sensor assembly for monitoring the condition of the adhesive layer. The ostomy base plate consists of an adhesive layer on the proximal surface, which adheres to the user's skin, and a top layer on the distal side with an opening. The sensor assembly, located between the adhesive layer and the top layer, comprises multiple electrodes with electrical connection parts. These electrical connection parts extend through the top layer opening and can be connected to a removable data monitor.
The primary purpose of the sensor assembly is to communicate information about the state of the adhesive layer to the removable data monitor. This information can include details about erosion of the adhesive layer, leakage of stomal output relative to the adhesive layer, and the classification of stomal output leakage conditions. By monitoring these factors, the ostomy base plate can provide valuable insights into the condition of the adhesive layer and help users manage their ostomy more effectively.
The adhesive layer of the ostomy base plate can be made of either a water-soluble hydrocolloid or a water-swellable hydrocolloid, providing flexibility and comfort for the user. Additionally, the patent mentions the inclusion of a support layer and a reinforcement layer in some embodiments. The support layer houses the electrodes on its proximal side, while the reinforcement layer extends through the top layer opening, providing a reinforced monitor interface for electrical connection between the electrodes and the removable data monitor. The reinforcement layer can be a flex circuit or consist of conductive paths connected to the electrodes.
In certain embodiments, a second adhesive layer is included between the top layer and the sensor assembly, aligned with the top layer opening. This second adhesive layer can also be made of a water-soluble or water-swellable hydrocolloid.
Overall, this patent presents an ostomy base plate with a sensor assembly that offers enhanced monitoring capabilities for the adhesive layer. By providing real-time information about the condition of the adhesive layer, this innovation has the potential to improve the management and comfort of individuals with ostomies.
