The description focuses on mechanical and electronic control of gas flow based on user input and monitoring, with no mention of AI or ML algorithms for decision-making or control.
Yes
The device sets, monitors, and controls gas flows of medical grade gases for oxygenation of a patient's blood during extracorporeal circulation, which directly impacts the physiological function of the patient.
No
The device is intended to control and monitor gas flows of medical grade gases during cardiopulmonary bypass to oxygenate a patient's blood. It does not perform any diagnostic function such as identifying a disease or condition.
No
The device description clearly outlines physical hardware components including a base unit with dimensions and weight, inlet and outlet gas connections, a user interface with keys and displays, and a 24V/CAN connector for power and communication. It is described as a physical accessory to a heart-lung machine console.
Based on the provided information, the Stöckert Gas Blenders are not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to "set monitor and control gas flows of medical grade gases (air/02/CO2) during cardiopulmonary bypass." This involves managing gases delivered to a patient's blood outside the body during a medical procedure.
- Device Description: The device description details how the gas blender mixes and controls gases for delivery to an oxygenator, which is part of an extracorporeal circulation circuit.
- Lack of IVD Characteristics: An IVD device is typically used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Stöckert Gas Blenders do not perform any analysis or testing of bodily specimens. They are involved in the delivery of gases to the blood during a procedure, not the analysis of the blood itself.
The device is clearly intended for use in a medical procedure involving extracorporeal circulation, not for in vitro diagnostic testing.
N/A
Intended Use / Indications for Use
The Stöckert Gas Blenders (2L, 5L, and 10L) are intended to enable qualified personnel to set monitor and control gas flows of medical grade gases (air/O2/CO2) during cardiopulmonary bypass. The Stöckert Gas Blenders are used as components of or optional accessories to the Stöckert S5 System (or any compatible Sorin system using the S5 firmware versions of 3.0 or greater) for periods of six hours or less.

Device Description
Physical Description
The Stöckert Gas Blender Base Unit is 200 mm wide, 185 mm high, and 270 mm deep and it weighs 2.5 kg. It can be used either from a suitable horizontal surface such as a table or cart or it can be mounted on one of the masts (using the mast holder). It is attached to HLM console with the supplied 24V/CAN connector. This connection provides both power and communication between the Stöckert Gas Blender and the System Display Panel of the HLM. The Stöckert Gas Blenders are designed to provide a maximum mixed gas flow rate of 2L/min, 5L/min or 10 L/min depending on the model used to allow the perfusionist to purge the oxygenator with gas during the priming process.
The front panel is the user interface and includes the on/off key, displays and controls. The rear panel houses the three inlet gas connections, the gas mix outlet, and the 24V/CAN connector. Gas line connectors are fast release connectors, consisting of a male connector (installed on the tubing) and a coupler socket (on the housing of the Gas Blender). Both sets (male and female) of connectors are labeled with the respective gas for which they are intended to be used.
How the Device Functions
The Stöckert Gas Blenders enable the qualified perfusionists who are managing the cardiopulmonary bypass circuit using a Stöckert S5 or Sorin C5 System to precisely set, monitor and control the gas flows required for the oxygenation of the patient's blood during extracorporeal circulation. The supply sources for air, O2 and CO2 are connected to the rear inlets of the Stöckert Gas Blender and the gas mixture outlet is connected to the oxygenator (not supplied).
Scientific Concepts That Form the Basis for the Device
Cardiopulmonary bypass procedures require oxygenation of the patient's blood while the heart and lungs are at rest.
Significant Physical and Performance Characteristics of the Device, such as Device Design, Material Used, and Physical Properties
The Stöckert Gas Blenders are optional accessories to and designed to be operated with the Stöckert S5 System/Sorin C5 System. They cannot be operated independently from the heart lung machine console. The values for total gas flow (air + O2), FiO2 and CO2 can be adjusted independently without affecting the remaining two values. Gas flow is displayed at both the Stöckert Gas Blender base unit and the remote display module situated in the Stöckert S5 System/Sorin C5 System "control desk" or "System Panel." Set values and actual values are continuously monitored and any discrepancy between them causes both optical and acoustic alarms. If desired, the perfusionist may set alarm limits at the remote display module to monitor the blood flow/gas flow ratio for the arterial pump.
