The utility model relates to the field of medical equipment, concretely relates to supplementary nose cup device of special breath-hold of CT inspection, include: an elastic bandage, a nose covering shell and an air suction shell; the nasal cavity is formed in the nasal cavity sleeving shell, the air suction cavity is formed in the air suction shell, two air ventilation through holes are formed in the nasal cavity sleeving shell at the lower end corresponding to the nostrils of a patient, two air ventilation head holes are formed in the air suction shell at the lower end corresponding to the two air ventilation through holes, and one-way air ventilation heads are installed in the air ventilation head holes. The one-way ventilation head is made of silica gel and is integrally of a conical structure with two oblique planes on two sides and narrow upper part, so that a ventilation seam at the upper end of the one-way ventilation head is in a joint closed state in a normal state, and the external pressure of the one-way ventilation head presses the ventilation seam to be tightly jointed and cannot ventilate. When a patient needs to inhale, the air pressure in the inhaling cavity is smaller than the air pressure in the one-way ventilating head, so that the one-way ventilating head enables the nostril of the patient to inhale and exhale, and the effect of keeping the breath of the patient is achieved. |
