Description

A nasal irrigation device for negative pressure suction

Technical Field

The utility model relates to the technical field of medical care products, in particular to a nasal irrigation device for negative pressure suction.

Background technique

Rhinitis and sinusitis are common and frequently occurring diseases in clinical practice. Nasal irrigation and nasal negative pressure are widely used in clinical practice. Many young children visit the ENT department. When children have a cold, rhinitis or sinusitis, secretions are produced in the nasal cavity to form nasal mucus, which cannot be blown out. Over time, the mucus will absorb foreign matter and dry up, blocking the nostrils and affecting breathing. Therefore, external tools are needed to suck out the mucus and foreign matter in the child's nasal cavity to clean the nasal cavity.

In the prior art, the common treatment method used in hospitals is to use a syringe to draw saline solution, and then flush the saline solution into the nasal cavity to dilute the mucus and soften the secretions. In the other nasal cavity, a special nasal suction head is connected to a negative pressure aspirator to suck out the secretions through the outer opening of the nostril. During the operation, the discomfort caused by flushing and negative pressure suction makes the children struggle violently, cry, and fail to cooperate well, which increases the difficulty of the operation. Therefore, this application provides a nasal irrigation device with negative pressure suction to meet the needs.

Utility Model Content

The technical problem to be solved by the utility model is to provide a nasal irrigation device with negative pressure suction to solve the problem that the commonly used treatment method in existing hospitals is to use a syringe to suck physiological saline, and then rinse the physiological saline into the nasal cavity to achieve the effect of diluting nasal mucus and softening secretions, and use a negative pressure suction device connected to a special nasal suction head in the other nasal cavity to suck out through the outer opening of the nostril.
