Disposable arterial blood gas puncture patch

The invention relates to the technical field of arterial puncture, and specifically relates to a disposable arterial blood gas puncture patch. The puncture patch can display correct arteriovenous puncture points and is convenient for medical staff to blindly collect arterial blood gas, so that the peripheral blood vessels and nerves of patients can be prevented from being stabbed by mistake. The medical staff can remove a non-toxic sealed protective film, tightly attach a silicone skin patch to the skin of a patient and wind four secondary fixation binding bands on the body of the patient to fix with four fixing velcro tapes; sterilized strip cotton disinfects the surface of the skin in a blood gas puncture strip hole; and two color-changing induction coatings perform induction change through the skin surface temperature and arterial blood vessel temperature of the patient, and as the skin surface temperature is relatively lower than the arterial blood vessel temperature, the color-changing induction coating
