Detailed Implementation

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please refer to Figure 1 and Figure 3 The present invention provides the following technical solution: an infant blood collection device, comprising a scalp needle tubing 1, a venous tubing 2, an arterial tubing 3, a scalp needle 4, a protective sleeve 5, a blood collection needle 6, an arterial blood collection tube 7, a blood collection tube cap 8, and a tubing clamp 9. The scalp needle 4 is fixedly connected to the front end of the scalp needle tubing 1. A needle holding plate is provided on one side of the scalp needle 4. A protective sleeve 5 is fitted onto the scalp needle 4. The venous tubing 2 and the arterial tubing 3 are provided at the rear end of the scalp needle tubing 1. The venous tubing 2 and the arterial tubing 3 are connected to the scalp needle tubing 1. A tubing clamp 9 is clamped and fixed on both the venous tubing 2 and the arterial tubing 3.

[0021] The end of the intravenous tubing 2 is equipped with a blood collection needle 6, and a rubber sleeve is attached to the top of the blood collection needle 6.

[0022] The arterial hose 3 is movably connected to an arterial blood collection tube 7, and the outer surface of the arterial blood collection tube 7 is provided with a scale line 701.
