Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an arterial catheter puncture needle and an arterial catheter puncture bag. Background Art

[0002] Invasive arterial blood pressure detection technology is a technology that places an indwelling needle in an arterial blood vessel through the body surface and directly measures arterial pressure through a pressure transducer. Compared with the common non-invasive blood pressure monitoring in clinical practice, this technology can provide continuous, reliable and accurate monitoring data. In clinical practice, the radial artery is the most commonly used arterial puncture site for invasive arterial blood pressure detection. This is because the artery is superficial and relatively fixed, so it is easier to puncture and place a catheter.

[0003] The handle of the arterial indwelling needle used in the prior art is usually configured as a cylindrical structure. With such a structural configuration, after the indwelling needle is fixed, a linear contact is formed between the handle and the patient's skin, which may cause pressure injuries to the patient's skin and have an adverse effect on the patient's treatment.

[0004] Therefore, how to prevent the handle of the indwelling needle from pressing the patient's skin and causing pressure injury after the indwelling needle is fixed is a technical problem that needs to be solved urgently in the prior art. Utility Model Content

The indwelling needle body portion 1 includes a needle tube section 3 and a needle handle section 4. The surface of the needle handle section 4 in contact with the human skin is set as a planar structure.

[0033] When using the puncture needle for arterial catheterization according to the present utility model, setting the surface of the needle handle section 4 in contact with the human skin as a planar structure can increase the contact area between the needle handle section 4 and the human skin, avoid line contact between the two, and thus effectively prevent pressure injuries to the patient's skin during the indwelling period of the arterial catheterization puncture needle, improving the patient's rehabilitation effect.
