Device Description
The Pulsed Oxygen Conserving Device or "POCD" is intended to be used as an accessory to an oxygen supply system to reduce or conserve the amount of oxygen used by the patient. The POCD is a battery operated electronic device that is microprocessor controlled and contains a capacitive breath sensor and a normally closed valve. When installed between the oxygen supply and patient's nasal cannula, the device detects the patient's inhalation opens the valve according to the device's breath skipping algorithm and delivers a preset bolus of oxygen to the patient. The valve closes and conserves the oxygen that would have been wasted during the end of inhalation and during exhalation.
More Information

No
The description mentions a "microprocessor controlled" device with a "breath skipping algorithm," which suggests traditional programming logic rather than AI/ML. There is no mention of AI, ML, or related terms, nor any description of training or test data sets typically associated with AI/ML development.

No
The device conserves oxygen for patients and is described as an accessory to an oxygen supply system. It does not treat or diagnose a disease.

No

The device is described as an accessory to an oxygen supply system to conserve oxygen for patients; it does not diagnose a medical condition.

No

The device description explicitly states it is a "battery operated electronic device that is microprocessor controlled and contains a capacitive breath sensor and a normally closed valve." This indicates the device includes hardware components beyond just software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The description clearly states the device is an "accessory to an oxygen supply system to reduce or conserve the amount of oxygen used by the patient." It works by detecting the patient's breath and controlling the flow of oxygen.
  • Lack of Biological Sample Analysis: There is no mention of the device analyzing any biological samples from the patient. Its function is purely related to the delivery of oxygen.
  • Intended Use: The intended use is to conserve oxygen for patients prescribed supplemental oxygen, not to diagnose or monitor a disease through in vitro testing.

Therefore, the POCD Pulsed Oxygen Conserving Device falls under the category of a medical device, but not an In Vitro Diagnostic device.

Device Description

The Pulsed Oxygen Conserving Device or "POCD" is intended to be used as an accessory to an oxygen supply system to reduce or conserve the amount of oxygen used by the patient. The POCD is a battery operated electronic device that is microprocessor controlled and contains a capacitive breath sensor and a normally closed valve. When installed between the oxygen supply and patient's nasal cannula, the device detects the patient's inhalation opens the valve according to the device's breath skipping algorithm and delivers a preset bolus of oxygen to the patient. The valve closes and conserves the oxygen that would have been wasted during the end of inhalation and during exhalation.

The POCD is intended to be used with USP bottled oxygen and nasal cannulas and is installed as shown in Figure 1.

The front panel of the POCD has a selector switch and a battery status light. When the selector switch is set to the "Bat" position the battery status light will illuminate to give the user an indication of the condition of the battery in the device. I n addition to providing battery status information to the user while in the "Bat" setting, the POCD will indicate a low battery condition by flashing the battery status light Red if the unit is in any of the operational settings; "4", "3", "2", or "1", and the battery voltage falls below 1.10V.

When the selector switch is set to "4", "3", "2", or "1" the device operates as follows:

The capacitive pressure transducer changes its capacitance in response to the negative pressure produced by the user's inhalation effort. This change in capacitance is converted into a change in voltage and is amplified. When this amplified voltage exceeds the reference voltage of the comparator, the comparator's output changes state. This change is input into the microprocessor. The microprocessor then opens the valve for a preset time period to deliver 35 ml of oxygen or indexes a counter in the breath skipping algorithm.

The breath skipping algorithm, a clinically proven method of maintaining equivalent blood oxygen saturation versus prescribed continuous oxygen flow rates and used in all three of the predicate devices, works by delivering a bolus of oxygen to the user according to the following schedule:

Selector Switch SettingEquivalent Continuous Flow PrescriptionPOCD Breath Skipping Algorithm
44 lpmDelivery on almost every breath (99%)
33 IpmDelivery on 3 out of 4 breaths (75%)
22 IpmDelivery on every other breath (50%)
11 IpmDelivery on 1 out of 4 breaths (25%)

The POCD contains an alarm package which is designed to alert the user in the event of disconnection or restriction of the cannula or unit malfunction. The POCD will produce an audible alarm tone to alert the user if it has not detected sufficient negative pressure to cause the comparator output to change states within 30 seconds. The POCD will also produce an intermittent audible tone if the device's continuous self check routine has detected a matfunction in the microprocessor or software control code.

Technological Characteristics and Substantial Equivalence

The Pulsed Oxygen Conserving Device or "POCD" is intended to be used as an accessory to an oxygen supply system to reduce or conserve the amount of oxygen used by the patient. The POCD is a battery operated electronic device that is microprocessor controlled and contains a capacitive breath sensor and a normally closed valve. When installed between the oxygen supply and patient's nasal cannula, the device detects the patient's inhalation opens the valve according to the device's breath skipping algorithm and delivers a preset bolus of oxygen to the patient. The valve closes and conserves the oxygen that would have been wasted during the end of inhalation and during exhalation.

The POCD is intended to be used with USP bottled oxygen and nasal cannulas and is installed as shown in Figure 1.

Image /page/1/Figure/3 description: The image shows a diagram of an oxygen delivery system. The system includes a USP bottled oxygen tank connected to a pressure regulator and valve assembly that delivers 4 lpm flow at 20 psi. The oxygen then flows through oxygen supply tubing to a POCD oxygen conserver, and finally to a nasal cannula.

The front panel of the POCD has a selector switch and a battery status light. When the selector switch is set to the "Bat" position the battery status light will illuminate to give the user an indication of the condition of the battery in the device. I n addition to providing battery status information to the user while in the "Bat" setting, the POCD will indicate a low battery condition by flashing the battery status light Red if the unit is in any of the operational settings; "4", "3", "2", or "1", and the battery voltage falls below 1.10V.

When the selector switch is set to "4", "3", "2", or "1" the device operates as follows:

The capacitive pressure transducer changes its capacitance in response to the negative pressure produced by the user's inhalation effort. This change in capacitance is converted into a change in voltage and is amplified. When this amplified voltage exceeds the reference voltage of the comparator, the comparator's output changes state. This change is input into the microprocessor. The microprocessor then opens the valve for a preset time period to deliver 35 ml of oxygen or indexes a counter in the breath skipping algorithm.

The breath skipping algorithm, a clinically proven method of maintaining equivalent blood oxygen saturation versus prescribed continuous oxygen flow rates and used in all three of the predicate devices, works by delivering a bolus of oxygen to the user according to the following schedule:

| Selector Switch
Setting | Equivalent
Continuous Flow
Prescription | POCD Breath Skipping Algorithm |
|----------------------------|-----------------------------------------------|---------------------------------------|
| 4 | 4 lpm | Delivery on almost every breath (99%) |
| 3 | 3 Ipm | Delivery on 3 out of 4 breaths (75%) |
| 2 | 2 Ipm | Delivery on every other breath (50%) |
| 1 | 1 Ipm | Delivery on 1 out of 4 breaths (25%) |

The POCD contains an alarm package which is designed to alert the user in the event of disconnection or restriction of the cannula or unit malfunction. The POCD will produce an audible alarm tone to alert the user if it has not detected sufficient negative pressure to cause the comparator output to change states within 30 seconds. The POCD will also produce an intermittent audible tone if the device's continuous self check routine has detected a matfunction in the microprocessor or software control code.

The POCD is substantially equivalent in intended use and principal of operation to other oxygen conserving devices including the CHAD Therapeutics Oxymatic-24 (K884562), CHAD Therapeutics Oxymatic Electronic Oxygen Conserver (K852650), and the Airsep Impulse (K962766). These predicate devices, like the POCD, are electronic products that use a breath sensor and normally closed valve. Additionally, the predicate devices. like the POCD. use a breath skipping algorithm to conserve oxygen while maintaining patient oxygen saturation levels equivalent to 1 to 4 liter per minute continuous oxygen flow delivery.

Performance Data

Extensive functional testing of the POCD has been performed. In addition, testing of the device has been performed under various environmental conditions, including impact/drop testing, storage temperature testing, electromagnetic interference testing, electrostatic discharge testing and surface temperature testing. Power supply testing was also performed; these tests included battery life testing and low power indicator testing. The functional, environmental and power supply testing performed on the device demonstrated that it meets its performance objectives and complies with applicable FDA guidelines.
