Device Facts

• Record ID: K991644
• Device Name: MICROGAS 7650 TRANSCUTANEOUS MONITOR
• Applicant: Linde Medical Sensors AG
• Product Code: KLK · Anesthesiology
• Decision Date: May 21, 1999
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 868.2500
• Device Class: Class 2
• Attributes: Pediatric

Intended Use

The Linde Transcutaneous Monitor is intended to measure the partial pressure of oxygen and carbon dioxide that passes through the cutaneous layer of the skin of an infant who is not under gas anesthesia by a sensor attached to the surface of the infant's skin.

Device Story

The MicroGas 7650 is a transcutaneous monitor designed to measure partial pressures of oxygen and carbon dioxide in infants. The device utilizes a sensor attached to the infant's skin to detect gas diffusion through the cutaneous layer. It provides continuous monitoring of blood gas levels, allowing clinicians to assess respiratory status and oxygenation. The device is intended for use in clinical settings by healthcare professionals. It serves as a non-invasive alternative to arterial blood gas sampling, helping clinicians make informed decisions regarding respiratory support and patient management, thereby potentially improving patient outcomes by providing real-time physiological data.

Clinical Evidence

No clinical or non-clinical tests were performed or submitted for this notification as the device is identical to the predicate. Refer to PMA P810037 for supporting data.

Technological Characteristics

Transcutaneous gas monitoring system; sensor-based measurement of oxygen and carbon dioxide partial pressures; intended for infant use; identical to predicate device P810037.

Indications for Use

Indicated for infants not under gas anesthesia for the measurement of transcutaneous partial pressure of oxygen and carbon dioxide via a skin-surface sensor.

Regulatory Classification

Identification

A cutaneous oxygen (PcO2) monitor is a noninvasive, heated sensor (e.g., a Clark-type polargraphic electrode) placed on the patient's skin that is intended to monitor relative changes in the cutaneous oxygen tension.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 868.9. The special control is FDA's “Class II Special Controls Guidance Document: Cutaneous Carbon Dioxide (PcCO2) and Oxygen (PcO2) Monitors; Guidance for Industry and FDA.” See § 868.1(e) for the availability of this guidance document.

Predicate Devices

• Kontron MicroGas 7650 (P810037)

### Common Name:

Cutaneous Blood Gas Monitor

Intended Use:

The Linde Transcutaneous Monitor is intended to measure the partial pressure of oxygen and carbon dioxide that passes through the cutaneous layer of the skin of an infant who is not under gas anesthesia by a sensor attached to the surface of the infant's skin.

#### Description of the Device:

Detailed description of the device is contained in the MicroGas 7650 Operator's Manual located in Appendix 2 of this document.

Clinical and Non-Clinical Tests of Equivalency:

The MicroGas 7650 is exactly the same device as the MicroGas 7650 distributed by Kontron Instruments under PMA P810037. Both devices are manufactured by Linde Medical Sensors AG of Basel, Switzerland.

Because there are no differences other than labeling between the Linde MicroGas 7650 and the Kontron MicroGas 7650, no additional clinical or non-clinical tests were performed or submitted in the premarket notification. Refer to PMA number P810037 for this data.

Dear Mr. Palma:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
