Abstract

The invention relates to an atomization drug delivery instrument for paranasal sinuses. The atomization drug delivery instrument comprises an atomization tank; a lower gas inlet pipe is arranged under the atomization tank, compressed air can be pumped into the lower gas inlet pipe for atomizing liquid medicine at the bottom of the atomization tank, and the atomized liquid medicine reaches the upper part of the atomization tank and becomes atomized gas; a gas outlet pipe is arranged at one side of the atomization tank; an upper gas inlet pipe is arranged above the atomization tank; the compressed gas can be pumped into the upper gas inlet pipe for driving the atomized gas to enter the nasal cavity through the gas outlet pipe. The atomization drug delivery instrument has the beneficial effects that after being atomized by the compressed air, the liquid medicine is brought into the nasal cavity by means of siphonic effect, so that the atomized liquid medicine which is in a floating state is likely to reach the paranasal sinuses; by using a voice operated switch to control the work of the atomization tank, when a patient makes a sound, the soft palate is closed, and the atomized gas cannot enter the respiratory tract and only can move upwards to enter the paranasal sinuses, so that liquid medicine shunt is avoided.

Description

technical field

[0001] The invention relates to a medical device, in particular to a nasal sinus atomization drug delivery instrument. Background technique

[0002] Most of the current spray devices are intelligently used to treat rhinitis and pharyngitis. Because the sinuses are located deep in the nasal cavity and are connected to the nasal cavity through small tubes, general spray therapeutic devices cannot deliver the medicine to the affected area. There are also those that send the liquid medicine to the designated part through the principle of pulse vibration, but the structure is complicated and the cost is high. In addition, even if the medicinal liquid can be sent to the sinuses, because the nasal cavity is connected to the throat, most of the medicinal liquid will enter the throat and cause side effects. Contents of the invention

[0003] The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a nasal sinus atomization...

Examples

Embodiment

[0011] Example: such as figure 1 , a nasal sinus atomization drug delivery instrument, comprising an atomization tank 1, a lower air intake pipe 2 is provided below the atomization tank 1, an air outlet pipe 4 is provided on one side of the atomization tank 1, and an upper air intake pipe 2 is provided above the atomization tank 1 . The upper intake pipe 2 is connected with a compressor 5 provided with a voice-activated switch 6 . The air outlet pipe 4 is provided with a double nasal cavity catheter 7, and the double nasal cavity catheter 7 adopts a silica gel material.

[0012] During use, the double nasal cavity catheter 7 is stuffed into the double nasal cavity, and the double nasal cavity catheter 7 is connected with the atomizing tank and the double nasal cavity to form a closed environment. Compressed gas is fed into the lower air inlet pipe 2 to atomize the liquid medicine 8 placed at the bottom of the atomizing tank 1 and reach the top of the atomizing tank 1 to beco...
