Description

nasal douche

technical field

The invention relates to medical equipment for nasal cavity, in particular to a nasal cavity irrigation device.

Background technique

Among the auxiliary diagnostic methods for nasal diseases, collecting nasal secretions from patients for inflammatory cytological classification and counting is one of the important ways to assist in the diagnosis of nasal diseases. But at present there is only a nasal aspirator for sucking nasal secretions of infants and young children. This device has the disadvantages that the suction is too small, cannot be used for adults, and cannot perform nasal lavage on patients. Therefore lack a kind of medical device that can be used for adult, safe, non-invasive, simply lavage and collect patient's nasal secretion.

Contents of the invention

In order to overcome the deficiencies in the prior art above, the present invention provides a nasal lavage device with a simple and reasonable structure, which can lavage and collect nasal secretions of patients.

The purpose of the present invention is achieved through the following technical solutions: the nasal lavage device is characterized in that it includes a liquid storage head, a connecting sleeve, a suction nozzle and a plug ring, the connecting sleeve is inserted into the liquid storage head, and the extended end of the connecting sleeve There is a sharp mouth, the suction nozzle is set on the sharp mouth, the plug ring is a hollow structure, and the plug ring is set outside the suction nozzle.

In order to prevent the connecting sleeve from falling off, an anti-slip ring is provided under the connecting sleeve, and an anti-slip groove is provided in the liquid storage head, and the anti-slip ring is embedded in the anti-slip groove.

In order to prevent the suction nozzle from falling off, the suction nozzle and the pointed mouth are closely fitted.

In order to prevent the plug ring from falling off, the plug ring and the suction nozzle are tightly fitted.

The medicinal liquid contained in the liquid storage head is two-thirds of the capacity of the liquid storage head, which can meet the needs of lavage.

Physiological saline is contained in the liquid storage head, and nasal cavity lavage is performed on the patient.

The liquid storage head is made of rubber material. The rubber material is soft and easy to squeeze.

The connecting sleeve is made of polyethylene material. The polyethylene material is strong and allows for easy tip placement.

The suction nozzle is made of silicone material. The silicone material has a certain degree of softness and can be tightly matched with the connecting sleeve and the plug ring.

The plug ring is made of hard sponge material. The hard sponge material does not absorb water and has a certain degree of flexibility, which is convenient for the present invention to be tightly inserted into nostrils of different sizes to form negative pressure.

The use process of the present invention is:

Pour physiological saline into the liquid storage head to two-thirds of the capacity of the liquid storage head, connect the connection sleeve with the suction nozzle to the opening of the liquid storage head, and select a certain type of plug ring suitable for the size of the patient's anterior nostril to cover the suction nozzle.

The patient sits in a seat leaning forward at 60 degrees, breathes with the mouth open, and plugs the plug ring tightly into the front nostril on one side. The hard sponge plug ring can completely seal the patient's entire external nostril; press the liquid storage head firmly with the hand to pour the normal saline into the nasal cavity ;After staying for about 10 seconds, loosen the liquid storage head, and the negative pressure suction generated will completely suck out the saline in the nasal cavity; repeat this 10 times, and the nasal lavage fluid collected in the liquid storage head can be poured out for medical analysis .

Compared with the prior art, the present invention has the following advantages:

In the present invention, a different type of hard sponge plug ring is socketed on the suction nozzle. The plug ring can not only ensure that the lavage fluid and nasal secretions do not leak out, but also form a negative pressure, effectively increasing the suction force of the nasal cavity irrigator. So as to more effectively suck out and collect the lavage fluid and nasal secretion in the patient's nasal cavity, achieve the purpose of safe, non-invasive and adequate nasal lavage for the patient, and more effectively collect the inflammatory cells in the patient's nasal cavity for nasal diseases It can also be used for clinical treatment and scientific research of patients with nasal diseases. The invention can be used for patients of different ages, and can safely, non-invasively, simply and fully lavage and collect nasal secretions of patients.
