Portable fixable blood taking needle

Technical Field

The utility model belongs to blood sample collection equipment field, in particular to portable blood taking needle of fixing.

Background

In the prior art, blood assays are routine and important in vitro detection means required for disease diagnosis. All blood taking needles are disposable at present due to safety, and the clinical use amount is huge. During blood sampling, medical staff needing to execute blood sampling firstly finds the position of a blood vessel, feels according to experience, fixes the blood sampling needle by using an adhesive tape or a specific gesture after the puncture is successful, and then inserts a cannula needle connected with the rear end of the blood sampling needle into a connecting catheter and the cannula needle to take a certain amount of blood for censorship. The subsequent blood sampling process needs a certain time, and especially under the condition of large blood consumption, the fixation of the puncture needle after puncturing the blood vessel is very important.

The hand of patient's blood sampling position or blood sampling personnel shifts, then probably leads to the pjncture needle point to shift, if shift when obvious, or to penetrating the blood vessel to deeper, or deviate from the blood vessel chamber backward, these all will lead to the blood sampling failure, need the repetitive operation, increase patient's blood sampling misery, prolonged the blood sampling time simultaneously, increase the work load of doctorsing and nurses. And after the blood sampling is accomplished, medical personnel need go again to look for the cotton ball and press the hemostasis to the puncture point of patient's skin, have increased medical personnel's work load, and the patient loses the cotton ball very easily, leads to the puncture point to expose outside, increases the infection risk. There is an urgent need for a device that can conveniently fix a lancet.
