Device Story

QuickSleeper 5 is a reusable, computer-controlled injection system for dental local anesthesia. It consists of a handheld syringe, electronic control box, and wireless foot pedal. The device accepts standard 1.7 mL and 1.8 mL anesthetic cartridges (ISO 11499). The practitioner operates the device to perform intraosseous and mucosal injections. The system features a motorized handpiece that provides needle rotation for bone penetration and controlled plunger translation for anesthetic delivery. The electronic interface provides real-time audible and visual feedback regarding injection speed and site resistance. Three injection modes (Hi, IO, Lo) allow for technique optimization. The device is used in professional healthcare facilities by dental practitioners. The output (anesthetic delivery) is controlled by the user via the foot pedal, with the device providing automated flow and pressure regulation. This assists in precise anesthetic administration, potentially improving patient comfort during dental procedures.

Dear Adrienne Von Foller:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

## Technological Characteristics

The electronic motor of the QuickSleeper 5 system provides control over the delivery of anesthetic, with adjustable speed and pressure settings that allow the practitioner to optimize the injection process based on the specific needs of the procedure. It also includes an intraosseous setting, which enables rotational movement of the needle for bone penetration.

The ergonomic handpiece is designed with a "pen-like" grip. The system features both audible and visual indicators to provide real-time feedback to the practitioner. It is compatible with the manufacturer's needles and accommodates standard anesthetic cartridges of 1.7 mL and 1.8 mL sizes compatible with ISO 11499.

The system is equipped with a wireless foot pedal, handpiece mount, and handpiece stand. The control box includes firmware which includes programmable settings as well as basic presets that allow for varying injection techniques based on the specific needs of the procedure.
