Description

Disposable gravity nasal washing device

Technical field

The utility model belongs to the field of medical devices, and in particular relates to a nasal cavity irrigation device for rhinitis patients.

Background technique

Nasal cleaning, also known as nasal washing, nasal lavage or nasal irrigation, is a clinical method that uses a nasal irrigator to send cleaning fluid to the nasal cavity to achieve the purpose of cleaning the nasal cavity and providing drug treatment. Both European rhinosinusitis and nasal polyps diagnosis

According to the position paper EPOS (2012 edition) and the Guidelines for the Diagnosis and Treatment of Chronic Rhinosinusitis in my country (2012), nasal irrigation plays an important auxiliary therapeutic role.

At present, nasal irrigators can be divided into manual or electric based on the power source. Manual nasal irrigators need to use manual pressure to generate negative pressure to draw the cleaning fluid to flush the nasal cavity, while electric nasal irrigators need to use a negative pressure pump to generate negative pressure.

Flush the nasal cavity with traction cleaning solution.

The disadvantage of the above-mentioned nasal irrigator is that in order to reduce the risk of cross-infection among users, the nasal irrigator can only be reused by a single person. However, in a hospital medical environment, if the nasal irrigation equipment is to be reused, it needs to be reused after each use.

Cleaning, disinfection, and equipment use are inefficient and time-consuming. If it is defined as a single use, the cost of single use is high, and some patients can complete the entire treatment process without multiple uses.

Contents of the invention

The purpose of this utility model is to provide a disposable gravity-type electric nasal washing device. Compared with the existing technology, the device has a simple structure and low cost, is suitable for one-time use, and meets the use requirements of the medical environment of the hospital.

The solution adopted by the utility model is: a disposable gravity-type nasal washing device, which includes: a liquid storage bag, a liquid delivery tube, a connector, a nasal plug head; a liquid return pipe and a collection bag; what is unique is that: the storage bag The bottom of the liquid bag is equipped with a closed liquid storage bag

Socket, one end of the liquid feeding tube is equipped with a conical puncture device for the liquid feeding tube. When in use, the tapered puncture device for the liquid feeding tube is inserted into the closed socket of the liquid storage bag; the top of the collection bag is provided with a The collection bag has a closed socket, and one end of the liquid return pipe has a return

Liquid pipe cone-shaped puncture device; when in use, the liquid return pipe cone-shaped puncture device is inserted into the closed socket of the collection bag; the upper end of the connector is provided with two nasal plug heads in parallel, and the lower end of the connector is provided with a liquid inlet and liquid outlet; the liquid return pipe is

The end of the liquid delivery pipe is connected to the liquid outlet of the connector, and one end of the liquid delivery pipe is connected to the liquid inlet of the connector.

A flow regulator is also provided in the middle of the liquid delivery pipe, and the length of the flow regulator is not less than 20mm. The total length of the liquid delivery pipe 2 is not less than 1500mm.

The fluid storage bag contains hypertonic saline or other therapeutic fluids.

A single-use gravity-fed nasal irrigation device can be packaged in a sterile barrier system and sterilized by EO or irradiation to achieve sterility.

The beneficial effects of the utility model are: the above-mentioned disposable gravity nasal washing device has a simple structural design and low cost, and utilizes the pressure difference between high and low positions without the need for electric or manual pressure. Compared with the traditional nasal irrigation device, it can be used as a one-time use, which can meet the needs of low-frequency use by a single person in a medical environment. At the same time, the liquid storage bag can accurately configure the cleaning liquid in advance, making it more convenient during use. Users can also use it on their own in non-medical environments.
