This is a disposable flexible sealing sleeve for medical peripheral blood collection needles. It’s transparent. It has an overall bowl-shaped structure. Or it might have a design with raised parts. It looks like a small shallow bowl or dish. Its edges are rounded.There’s a slightly wider rim around its circumference. It has a compact and delicate size. This lets it fit perfectly over blood collection needles. It works for sealing and protecting the needles. Its simple appearance meets the cleanliness requirements for medical supplies. It’s a specialized protective component under In Vitro Diagnostic (IVD) Equipment Accessories and IVD Seals. It meets the hygiene standards of Medical Device Seals in disposable medical tools.
Product Features
1. Function
The sealing sleeve for medical blood collection needles is mainly used to seal and protect blood collection needles. When the needle isn’t being used, the sleeve fits tightly over it.On one hand, it stops the needle from getting damaged by external impact or friction. On the other hand, it blocks contaminants well. Things like air, dust, and microorganisms. This keeps the needle in a sterile state. It also makes sure subsequent blood collection operations are hygienic and safe.Besides that, it stops medical staff or other people from being accidentally stuck by the needle. This reduces the risk of infection. This matches the protective role of Sterile Medical Seals and medical silicone seal (for silicone-based variants) in disposable medical devices.
2. Required Characteristics
1)Excellent Sealing PerformanceIt must fit tightly against the blood collection needle. There should be no gaps. It blocks external contaminants from getting in effectively. It also stops liquids like residual blood inside the needle from leaking. This keeps a sterile environment. This sealing capability meets the strict standards of Medical Grade Silicone Seals and Diagnostic Device Gaskets for IVD-related components.
2)Medical-Grade SafetyIt’s made of medical-grade materials. Like rubber or silicone that meets standards. These materials are non-toxic, non-irritating, and non-allergenic. When it touches the human body or blood, it doesn’t release harmful substances. This protects human health and blood safety. This is consistent with the safety specifications of Medical Vial Cap Seals and other medical sealing products.
3)Appropriate Elasticity and ToughnessIt has a certain degree of elasticity. This makes it easy to fit over the needle. After installation, it can keep its shape. It won’t deform or crack. It also has good toughness. It can stand a certain amount of pulling and squeezing. This makes sure it has a long service life. This mechanical property meets the performance requirements of IVD Seals and Silicone Medical Components (for flexible variants).
4)Transparent VisibilityIt’s usually made of transparent material. This lets medical staff check the needle’s condition easily. Like whether there are foreign objects or blood residues on the needle. This helps them find issues in time. This design meets the practical needs of Diagnostic Device Gaskets and accessories for visual inspection in medical scenarios.
5)Precise Dimensional AdaptabilityIts size must match the corresponding blood collection needle exactly. It should be easy to put on. It won’t fall off because it’s too loose. It also won’t be hard to handle because it’s too tight. This dimensional precision is like the fitting standards of Freezer Tube Seals and Medical Device Seals for small medical components.
