Sterile Needle 21G x 3 Deep

Sterile needle 21G x 3 Profondo is a precision medical device intended for hospital, outpatient and home use for the administration of solutions, the collection of blood samples and other invasive medical practices. It is made with high quality materials according to rigorous sterilization standards, to guarantee maximum safety during each procedure. The needle, 21 gauge with a length of 3 inches, offers a perfect compromise between smoothness and resistance, making it ideal for accessing deep anatomical sites. The high level of sharpness significantly reduces the pain perceived by the patient during skin and tissue penetration. The special protective cap safeguards sterility and allows safe transport. Each needle is individually packaged in blister packs for single use, thus guaranteeing the total absence of cross-contamination between patients or operators. Compatible with all the main types of syringe thanks to the universal Luer-type conical connection, it is particularly flexible in routine and emergency nursing and medical applications. Internal lubrication facilitates insertion, preserving the surrounding tissues and reducing the risk of trauma. The 21G x 3 Profondo sterile needle also stands out for its excellent handling and cutting precision. Each package is clearly identifiable and contains all the information relating to compliance with the most stringent quality and safety standards.

Therapeutic Indications

The sterile 21G x 3 Deep needle is indicated for a wide variety of medical practices that involve the introduction of liquids into the body or their removal. It finds application in the intramuscular, intravenous and subcutaneous administration of drugs, in the sampling of venous blood, in the infusion of hydrating solutions, antibiotics, chemotherapy and other therapeutic compounds. Thanks to its length and specific caliber, it is particularly recommended in situations where it is necessary to reach greater tissue depths than standard needles, for example on patients with thick adipose tissue or for procedures that require precision in the inoculation depth. It is frequently used in anesthesia for the blockade of nerve plexuses, in procedures for taking deep biological samples, in the aspiration of pathological liquids and in the application of treatments that require overcoming different tissue layers. It is also used in the collection of samples for cytological and bacteriological analyses. In the veterinary field it is useful in maneuvers on large animals. The 21G x 3 Profondo sterile needle is suitable for supporting practice both in hospital and in outpatient and home environments, adapting to the requests of doctors, nurses and qualified healthcare personnel. It has no age restrictions for use, as long as it is administered by expert operators trained in the use of invasive devices.

Composition

Main component: Medical grade stainless steel for the cannula, selected for its high sterilization tolerance and resistance to both mechanical and chemical factors. The surface of the cannula is treated with a triple polishing and sharpening process to maximize atraumatic penetration. The protective cap and needle holder are made of non-toxic, impact-resistant medical polypropylene, compatible with various pharmaceutical solvents. The Luer connection is made of plastic material certified for contact with drugs and blood solutions. Each needle is lubricated internally, using medical silicone substances, to ensure fluid movement without creating friction or damage to the structures it passes through. All materials are free from latex, PVC and phthalates, reducing the risk of allergic reactions. The primary packaging is a firmly sealed plastic blister, completely transparent and free from unauthorized openings, designed to maximize the protection of the product from external contamination. The secondary package contains the necessary identification information, instructions for use, indications on sterility and compliance with CE regulations.

Contraindications

The sterile 21G x 3 Deep needle must not be used in subjects known to have hypersensitivity reactions or allergies to medical steels or materials used in the packaging and plastic components of the device. Use is contraindicated if the package is damaged, opened or shows any sign of compromised sterility, given the risk of infection or septic complications. Use is not recommended in patients with coagulation disorders, marked haematological deficits or suffering from severe thrombocytopenia, unless there are compelling clinical needs assessed by the responsible doctor. It must not be used in the presence of skin infections localized in the area intended for the puncture, to avoid the spread of infectious agents. The reuse of the sterile needle is absolutely prohibited and involves very serious risks of cross infection. Caution and medical evaluation are recommended before use in immunocompromised or very debilitated subjects, especially in cases where the crossing of deep body layers or access to anatomical spaces not directly visible is expected.

Safety of the drug for the species

The use of the sterile 21G x 3 Profondo needle guarantees high safety standards for both the operator and the patient, thanks to the sterility certified through highly controlled processes of ethylene oxide or gamma rays, with validation of the sterilization cycles. The geometry of the tip reduces the risk of needle breakage during tissue penetration, while the robustness of the stainless material prevents accidental bending which could cause trauma or retention of fragments. The universal Luer connection prevents any risk of loosening or disconnection during pressurized procedures or prolonged infusions. The tests on the materials ensure the absence of the release of toxic substances, making the device suitable for use even on particularly sensitive subjects and children. The risk of infections is virtually eliminated by the adoption of rigorous aseptic practices and the individual hermetic packaging of each needle. The absence of latex and plasticizers reduces allergic reactions to almost zero. Any complications remain sporadic and are mostly due to incorrect use or use that does not comply with the methods indicated in the instructions for use.

Precautions

Before use, it is essential to check the integrity of the packaging and the expiry date shown on the secondary packaging. Operators must always use disposable gloves in order to ensure the maintenance of a sterile environment during all phases of handling and administration. After use, the needle must be immediately disposed of in special containers for pungent or sharp objects, in order to prevent the risk of accidental needle sticks to healthcare workers and the spread of blood-borne pathogens. It is recommended to handle the needle avoiding unnecessary bending or sudden movements which could compromise its structural resistance and effectiveness. If used for multiple procedures on the same patient, always use a new needle for each skin access. In case of previous experience of allergic reactions to steel or medical silicones, inform medical personnel in advance. The insertion procedure must be carried out by personnel trained through repeated practice and in-depth knowledge of the anatomy of the injection or sampling site.

Method of administration

The sterile 21G x 3 Profondo needle must be removed from the blister only at the time of actual use, maintaining maximum attention at all times to avoid any risk of contamination. After connecting the needle to the syringe by pressing or screwing the Luer fitting, remove the protective cap only immediately before skin penetration. Carefully disinfect the skin in the chosen area, choose the appropriate entry angle based on the type of procedure (intramuscular, intravenous, subcutaneous injection or sampling), then proceed with insertion with a quick and decisive movement in order to reduce patient discomfort. Once the procedure has been completed, extract the needle with a linear movement avoiding twisting, then apply pressure to the entry site with a sterile swab. Proceed with the correct immediate disposal of the used device. Do not touch the tip of the needle and never attempt to reinsert the protective cap after use to avoid accidental needle sticks (no re-capping).

Treatment program

The use of the sterile 21G x 3 Profondo needle depends on the therapeutic plan established by the treating doctor or healthcare professional. For the administration of prolonged or repeated treatments, it is recommended to replace the needle with each new infusion, withdrawal or injection, even if performed within the same day, in order to reduce the risk of infection and tissue injury as much as possible. In cases of multidose treatments or vaccination campaigns, each session involves the use of a new, sterile needle for each patient. In case of deep venous access, the procedure must be performed in accordance with updated clinical protocols and in compliance with all asepsis and antisepsis indications. Where the treatment requires numerous manipulations and accesses, it is essential to ensure planning that takes into account the need for reserve materials and immediate disposal of used needles. The device adapts to the different administration schemes foreseen by national and international guidelines for intravenous and intramuscular treatments of drugs, parenteral nutrition or blood collection.

Target species

This device is intended for human use in medical, nursing, outpatient, hospital and, where applicable, home practices. Use in veterinary medicine is practicable on medium-large sized animals, always under the supervision of qualified personnel and according to specific veterinary protocols.
