Necessity of Needle Penetration and Drag Force Testing

Why You Must Need It

The importance of ニードルペネトレーションテスト そして drag force testing cannot be overstated in the context of patient safety and device performance. Medical needles must be easy to insert while minimizing discomfort and trauma to the skin and tissue. These factors directly influence the patient experience and are crucial for:

• Patient Comfort: Lower penetration forces contribute to less pain during injection.
• Clinical Effectiveness: Proper drag forces ensure smooth insertion and reduce the risk of damage to tissues or complications during injection.
• 規制遵守: Meeting ISO 7864 そして GB 15811 standards is essential for market approval in various countries.
• Needle Safety: Excessive forces during insertion can compromise the integrity of both the needle and the tissue being pierced, leading to complications.

By using the NPD-01 Needle Penetration and Drag Force Tester, manufacturers ensure that their products meet these critical requirements and avoid potential harm to patients.

動作原理

The working principle of the NPD-01 針入度・引張力試験機 involves inserting a needle into a specified substrate and recording the forces during the insertion process. The machine operates under the following steps:

1. Needle Insertion: The needle is held securely by the machine and inserted into a substrate (e.g., synthetic skin, rubber) at a constant speed.
2. 力測定: As the needle moves through the substrate, the load cell measures the 浸透力 (表面を破るのに必要な最初のピーク力）と 抗力 (針が材料を通過するのに必要な力）。.
3. データ記録:様々な刺入深度における力の値を記録し、針の性能を詳細に分析できる。.
4. フォース・プロフィール:結果として得られるグラフは、研究者やメーカーがさまざまな条件下での針の挙動を理解し、それに応じて設計を最適化するのに役立つ。.
