Visual Straight Needle

Visible straight needle is a disposable straight blood collection needle with a transparent visual structure. Its core components include the puncture lancet, tube and needle holder.

The biggest difference from ordinary needles is that the needle carrier is made of transparent material and features a hollow cavity design, known as the "visual blood return cavity." During the puncture, once the syringe tip enters the vein, blood quickly flows through the venous puncture needle into this transparent cavity. The operator can see the blood returning with the naked eye, clearly confirming the puncture was successful.

Improving Puncture Success Rate and Safety: Traditional blood collection is a "blind puncture," and success depends entirely on experience and feel. The visual straight needle turns puncture results from "guesswork" into "visible." Some patents clearly state that their design can effectively reduce blood collection errors, alleviate patient pain and psychological stress for medical staff, and improve the success rate of puncture.

Reducing occupational exposure risk: Needle handling after blood collection is a high-incidence point for  injuries. The design of the visible straight needle also incorporates safety concepts.

The "aperture" of the visible straight needle refers to the diameter of the vein needle, denoted as Gauge(G); the larger the number, the finer the diameter. 21G is one of the most commonly used specifications in clinical practice, suitable for most adults' routine intravenous blood collection, with a balanced puncture success rate and comfort. 22G is suitable for adult patients with average vascular condition, as puncture pain is milder. 23G is a thinner specification, suitable for children, the elderly, and patients with narrower, more fragile blood vessels, maximizing pain reduction and vascular protection.

The visual straight needle is not used independently; it usually forms a complete blood collection system with the following instruments:

Needle carrier: This is an essential intermediary device. The tail end of the visible straight needle (butt end) is inserted into the interface at the front end of the needle carrier (some are threaded), while the vacuum blood collection tube is pushed in from the rear end of the needle carrier, completing the connection between the needle tip and the blood collection tube.
