Intended Use

TK Safety Needle device is intended for use in the aspiration and injection of fluids for medical purposes. The TK Safety Needle is compatible for use with standard luer slip and luer lock syringes. Additionally, after withdrawal of the needle from the body, the attached needle safety shield can be manually activated to cover the needle immediately after use to minimize risk of accidental needle-stick.

Device Story

TK Safety Needle is a single-lumen hypodermic needle featuring a hinged safety sheath attached to the hub. Used by medical practitioners in clinical settings for fluid aspiration and injection. After withdrawal from the patient, the practitioner manually activates the sheath—using a finger, thumb, or surface activation—to cover the needle, minimizing accidental sharps injury. The hinge allows for positioning flexibility. The device is compatible with standard luer slip and luer lock syringes. It provides a physical barrier to protect healthcare workers from needle-stick injuries post-procedure.

Clinical Evidence

No clinical data. Bench testing only. Performance validated against ISO 7864:2016 (fragmentation, flow rate, penetration/drag force, bonding strength), ISO 80369-7:2016 (leakage, stress cracking, axial load, unscrewing, overriding), and ISO 23908 (sharps injury protection). Biocompatibility testing (ISO 10993-1) included cytotoxicity, sensitization, irritation, acute systemic toxicity, pyrogenicity, and hemocompatibility.

Technological Characteristics

Materials: Polypropylene (hub/sheath), stainless steel (needle). Lubricant: Silicone oil. Adhesive: Epoxy. Dimensions: 16G-30G, 1/2"-1 1/2" lengths. Sensing/Actuation: Manual hinged safety shield. Connectivity: None. Sterilization: Ethylene Oxide (EO) per ISO 11135. Standards: ISO 7864, ISO 80369-7, ISO 9626, ISO 23908, ISO 10993.

Indications for Use

Indicated for aspiration and injection of fluids for medical purposes in patients requiring hypodermic needle use. Compatible with standard luer slip and luer lock syringes.

Regulatory Classification

Identification

A hypodermic single lumen needle is a device intended to inject fluids into, or withdraw fluids from, parts of the body below the surface of the skin. The device consists of a metal tube that is sharpened at one end and at the other end joined to a female connector (hub) designed to mate with a male connector (nozzle) of a piston syringe or an intravascular administration set.

Dear Bai Baodong:

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 (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 located 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.

{1}------------------------------------------------

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
