Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 to 3, the present embodiment provides a safety blood collection needle, which includes a puncture needle 1, a needle handle 2, a blood collection tube end needle 3, a needle base 4, a hose 5, a release paper 7 and a clamping portion 6, wherein the puncture needle 1 is mounted on the needle handle 2, the blood collection tube end needle 3 is mounted on the needle base 4, and the needle handle 2 and the needle base 4 are connected through the hose 5. The blood collection tube end needle 3 is used to pierce a vacuum blood collection tube.

In this embodiment, the needle holder 4 is detachably connected with a needle cap 8, the blood collection tube end needle 3 is sealed in the needle cap 8, and the needle cap 8 is used for protecting the blood collection tube end needle 3. After the puncture needle 1 is punctured into the vein of a patient, blood does not directly flow out of the end needle 3 of the blood collecting tube.

Specifically, a grip part 6 is provided at the middle of the needle shaft 2, the grip part 6 includes a first grip piece 601, a second grip piece 602, and a body 603, the body 603 is fixed to the needle shaft 2 and extends in a direction perpendicular to the needle shaft 2, and the first grip piece 601 and the second grip piece 602 are respectively located at the top and bottom of the front side of the body 603. The operator's finger centre gripping clamping part 6, and the thumb contacts with second clamping piece 602, and the middle finger contacts with second clamping piece 602, and this has increased the area of contact of operator's finger and clamping part 6 widely, has not only improved the travelling comfort of centre gripping when the operator takes a blood sample effectively, and the stability of centre gripping is higher moreover, and the blood sampling process is safer.

Further specifically, the back side of the body 603 is coated with glue; one end of the release paper 7 is covered with the adhesive, and the other end is fixed on the needle seat 4. An operator peels off the release paper 7 on the needle handle 2 through the movable needle seat 4, the puncture needle 1 is punctured into the vein of a patient, and the viscose on the back surface of the body 603 is bonded with the skin of the patient, so that the puncture needle 1 is fixed more simply and conveniently, and the operation is safer.

Preferably, the body 603 is trapezoidal in shape, and the width of the body 603 gradually increases from the end close to the needle shaft 2 to the end far from the needle shaft 2, which enables the operator to grip the grip portion 6 more easily and comfortably.

It is further preferable that the first holding sheet 601, the second holding sheet 602 and the body 603 form a concave structure, which helps to increase the contact surface of the first holding sheet 601 and the second holding sheet 602 with the fingers of the operator, and further facilitates the fixation of the release paper 7 on the body 603.

In the present embodiment, the first clamping piece 601, the second clamping piece 602, and the body 603 are integrally formed, which makes the structure of the clamping part 6 simpler.

Preferably, the release paper 7 fixed to the needle holder 4 is fitted with the side surface of the needle holder 4, which enables the release paper 7 to be more stably fixed to the needle holder 4.

According to the safety blood taking needle, the first clamping piece 601 and the second clamping greatly increase the contact area between the fingers and the clamping part 6 when an operator takes blood, so that the comfort of clamping when the operator takes blood is effectively improved, and the stability of clamping is high.

In addition, the release paper 7 on the needle handle 2 is peeled off by moving the needle seat 4, and the adhesive on the back of the body 603 is adhered to the skin of a patient, so that the puncture needle 1 is fixed more simply and conveniently and the operation is safer.
