Technical Field
[0001] The utility model relates to the design and application field of a needle-free blood sampling device, and more specifically to a heparin cap connector device used for needle-free blood sampling. Background Art
[0002] In clinical practice, venous blood collection is a common nursing operation. Blood is usually collected by puncturing with a blood collection needle. However, if blood needs to be collected repeatedly, the entire puncture and blood collection process may be difficult, and multiple punctures will also increase the pain of the patient. In order to reduce repeated venous punctures, two needle-free blood collection methods are used clinically: connecting a blood collection needle to a venous indwelling needle and connecting a syringe to a venous indwelling needle.
[0003] When using a venous indwelling needle for blood collection, it is necessary to use a heparin cap connector to connect the heparin cap connector to the infusion tube body to achieve needle-free blood collection. When using the heparin cap connector, it is easy to have an unreliable connection problem, which affects the blood collection and infusion process.
[0004] In view of the above technical shortcomings, the present technical solution improves the structure of the heparin cap connector, so that it can not only be effectively clamped and fixed to avoid falling off during use, but also has a simpler and more practical structure and is convenient and quick to operate.
