The SurgiLance® Safety Lancet is a puncture device to obtain micro blood samples. The SurgiLance Safety Lancet has a sharps prevention feature to protect the user from a needlestick injury.
The MediPurpose SurgiLance® Safety Lancets is a needle or blade device used to prick a patient's finger to draw a micro-sample of blood which can then be tested for an array of diagnostic assays. Point-of-Care (POC) tests currently using micro-sample quantities of whole blood include glucose, cholesterol, HIV, Hepatitis, A1C, Allergies, Lactate, HgB, H.Pvlori. Creatinine, Mono, PT, D-Dimer, Anemia, Thyroid, Triglycerides, Ketones, Prostate, IgE. Chagas and more. Lancets are commonly used in hospitals, clinics, physician offices, laboratories, OB/GYN practices, oncology departments, emergency medical services, nursing homes and blood banks. The outside plastic casing is designed to be ergonomic for the user and compatible with the test site, usually a human finger. The device is available with either a needle or blade, each with different depths of penetration, to provide optimal blood flow for different applications and skin types.
The SurgiLance® Safety Lancet is safely retracted and concealed before and after use. The user simply removes the protective cap, places the red raised platform end onto the patient's test site, and gently push the lancet down against the test site to activate the lancet mechanism. Once the lancet is used, it is rendered inoperative, providing added safety for patient and clinician. The device is discarded in a sharps container after use.
The SurgiLance® Safety Lancet comes in six models: two low flow, one medium flow, one medium-high flow, and two high flows. The six models are differentiated by their casing color.
The provided text describes the MediPurpose SurgiLance® Safety Lancet, a device designed to obtain micro blood samples while incorporating a sharps prevention feature. However, it does not include information about specific acceptance criteria or a study proving that the device meets those criteria.
The information primarily focuses on:
- Device Description: What the device is, its purpose (pricking a patient's finger for micro-sample blood draws for various diagnostic assays), its target users, and its functionality (safely retracted and concealed needle/blade, rendered inoperative after use). It also mentions different models based on depth of penetration and blood flow.
- Intended Use: "A puncture device to obtain micro blood samples. The SurgiLance® Safety Lancet has a sharps prevention feature to protect the user from a needlestick injury."
- Similarities and Differences to Predicate Devices: Discusses technological characteristics, materials (medical grade stainless steel for needles/blades, plastics for housing), and biocompatibility.
- Conclusion: States that the device has the "same principles of operation, intended use, and technological characteristics as the predicate devices." It also explicitly mentions that "The sharps prevention feature was fully tested to the FDA's guidance document as demonstrated in the performance testing."
Missing Information:
The document mentions performance testing for the sharps prevention feature but does not provide any details about:
- Specific acceptance criteria (e.g., success rate of sharps prevention, penetration depth accuracy, blood volume obtained, usability metrics).
- The actual results of the "performance testing."
- Study design details (sample size, data provenance, expert involvement, adjudication, standalone vs. MRMC, ground truth type, training set details).
Based on the provided text, I cannot complete the table or answer the specific questions related to acceptance criteria and study details. The document confirms that testing occurred for the sharps prevention feature, but the results and methodologies are not described.
§ 878.4850 Blood lancets.
(a)
Single use only blood lancet with an integral sharps injury prevention feature —(1)Identification. A disposable blood lancet intended for a single use that is comprised of a single use blade attached to a solid, non-reusable base (including an integral sharps injury prevention feature) that is used to puncture the skin to obtain a drop of blood for diagnostic purposes. The integral sharps injury prevention feature allows the device to be used once and then renders it inoperable and incapable of further use.(2)
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.
(B) Handwashing instructions for the user before and after use of the device.
