Used by healthcare professionals, patients, or lay persons in clinical or home settings. Provides a sterile, single-use method for obtaining small blood samples; benefits patient by reducing risk of accidental needlestick injuries during blood collection.

Clinical Evidence

No clinical study included. Bench testing only. Simulated clinical use study performed on 500 samples per FDA guidance and ISO 23908 to evaluate safety mechanism; all samples met pre-established criteria. Biocompatibility testing (ISO 10993 series) confirmed no cytotoxicity, sensitization, irritation, systemic toxicity, or pyrogenicity.

Technological Characteristics

Single-use, spring-activated safety lancet. Materials: stainless steel needle, silicone oil, ABS, PS, PP, and calcium powder. Sterilization: radiation (SAL 10^-6). Gauge range: 16G to 38G. Design includes integral sharps injury prevention feature. Biocompatibility per ISO 10993.

Indications for Use

Indicated for capillary blood sampling in patients of all ages, intended for use by healthcare professionals or lay persons.

Regulatory Classification

Identification

The regulation covers four types of blood lancets: (a) Single use only blood lancet with an integral sharps injury prevention feature; (b) Single use only blood lancet without an integral sharps injury prevention feature; (c) Multiple use blood lancet for single patient use only; and (d) Multiple use blood lancet for multiple patient use. All are defined as disposable or reusable devices comprised of a blade attached to a base used to puncture the skin to obtain a drop of blood for diagnostic purposes.

Special Controls

*Classification.* Class II (special controls). The special controls are:(i) The design characteristics of the device must ensure that the structure and material composition are consistent with the intended use and must include a sharps injury prevention feature. (ii) Mechanical performance testing must demonstrate that the device will withstand forces encountered during use and that the integral sharps injury prevention feature will irreversibly disable the device after one use. (iii) The device must be demonstrated to be biocompatible. (iv) Sterility testing must demonstrate the sterility of any device component that breaches the skin ( *e.g.,* blade).(v) Labeling must include: (A) Detailed descriptions, with illustrations, of the proper use of the device and its sharps injury prevention feature.

Dear Ningning Wang:

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.
