Description
1. Introduction
In the medical field, blood collection is a fundamental and crucial procedure, and its accuracy directly impacts diagnostic results. Our butterfly needles are designed to achieve precise and efficient blood collection, working in harmony with vacutainers (butterfly needle and vacutainer), providing a reliable blood – collection solution for both medical staff and patients. The size specifications of butterfly needles (butterfly cannula size, butterfly needle gauge size, butterfly needle size chart) are key features, ensuring optimal performance in all blood – collection scenarios.
2. The Unique Design of Butterfly Needles
- Precise Manipulation: The butterfly – wing design of butterfly needles is their distinctive feature, providing excellent maneuverability for medical staff. The shape and position of the butterfly wings are carefully engineered, enabling medical staff to hold and guide the needle into the blood vessel precisely. This is especially beneficial when dealing with small or hard – to – locate blood vessels, significantly increasing the puncture success rate and reducing patient discomfort.
- Perfect Compatibility with Vacutainers: Our butterfly needles seamlessly integrate with vacutainers. During blood collection, simply connect the vacutainer to the interface of the butterfly needle, and blood will automatically flow into the tube due to the vacuum negative – pressure principle. This operation is simple and efficient. This combination not only improves blood – collection efficiency but also reduces the risk of blood exposure, ensuring the hygiene and safety of the blood – collection process.
3. Diverse Size Specifications
- Needle Gauge (Butterfly Needle Gauge Size): A range of needle gauges from 21G to 25G is available. The 21G needle has a relatively larger diameter, suitable for situations where a large amount of blood needs to be collected quickly. For example, in some special tests that require a large blood sample, it can speed up the blood – collection process. The 23G is a more general – purpose gauge, widely used in most routine blood – collection scenarios, meeting the needs of general patients and test items. The 25G needle has a thinner diameter, suitable for patients who are more sensitive to pain or those with thinner blood vessels, such as infants or patients with long – term illnesses that have caused blood vessels to narrow, effectively reducing the pain during puncture.
- Needle Length (Butterfly Cannula Size): The needle length usually ranges from 19mm to 25mm. The shorter 19mm needle length is suitable for superficial blood – vessel punctures, minimizing damage to surrounding tissues. The longer 25mm needle length can be used for blood collection from deeper – seated blood vessels, ensuring that the needle can accurately reach the target blood vessel.
- Size Chart (Butterfly Needle Size Chart): To assist medical staff in more conveniently selecting the appropriate butterfly – needle size, we provide a detailed size chart. The chart clearly shows the applicable scenarios corresponding to different needle gauges and lengths. For example, it indicates how to choose the most suitable blood – collection needle size for patients of different ages and physical conditions. By referring to the size chart, medical staff can make quick and accurate decisions, improving blood – collection efficiency and patient satisfaction.
4. Product Specifications
| Specification | Details |
|---|---|
| Material | The needle body is made of high – quality medical – grade stainless steel, ensuring strength and sharpness. It also has good biocompatibility, reducing irritation to the patient’s blood vessels. The butterfly – wing part is made of high – quality plastic, which has good toughness and a comfortable grip for easy operation. |
| Connection Method | The connection with the vacutainer adopts a standard interface to ensure a tight connection, prevent blood leakage, and guarantee a smooth blood – collection process. |
| Safety Device | Some models are equipped with an automatic retractable safety device. After blood collection, the needle automatically retracts into the protective sheath, effectively preventing accidental needle sticks. Other models use a lockable sheath that can be manually locked to cover the needle after blood collection, further ensuring the safety of medical staff and those around. |
5. Application Scenarios
- Hospital Laboratories: In hospital laboratories, a large number of different types of blood tests are carried out daily. The diverse size specifications of butterfly needles and their perfect combination with vacutainers enable them to meet the requirements of various test items for blood volume and blood – collection methods. Whether it’s a routine blood – count test or a special biochemical or immunological test, an appropriate – sized butterfly needle can be found for precise blood collection.
- Clinics: When clinics conduct daily diagnoses for patients, they focus on patient comfort and the accuracy of blood collection. The precise maneuverability and multiple size options of butterfly needles allow medical staff to select the most suitable needle according to the specific conditions of patients, such as age and blood – vessel status. Thinner – gauge needles can reduce pain for children or sensitive patients, while the general – purpose gauge can meet the needs of most adult patients.
- Mobile Blood – Collection Vehicles: In the scenario of mobile blood – collection vehicles, facing donors or patients of different ages and physical conditions, the flexibility and adaptability of butterfly needles are particularly important. The diverse size specifications ensure that blood – collection can be completed smoothly regardless of the blood – vessel conditions. At the same time, the convenient combination with vacutainers makes the blood – collection process more efficient, meeting the fast – paced and accurate blood – collection needs of mobile blood – collection vehicles.
