Problems solved by technology

[0002] The existing nasal cavity inhalation drug delivery device generally includes a syringe, and a nozzle is arranged at the front end of the syringe. Delivery is like in the nasal cavity, but due to design defects in the existing nasal cavity inhalation drug delivery device, the liquid dispersion effect during the drug delivery process is not good, the droplet particles are large, it is not easy to inhale the drug into the nasal cavity, and there is no spray buffer device , when the drug enters the nasal cavity, the pressure is too high, which brings discomfort to the patient

Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0026] Such as Figures 1 to 3 A nasal inhalation drug delivery device shown includes a main body sleeve 1, a push rod 2 is arranged in the main body sleeve 1, a piston 3 is arranged on the push rod 2, and a piston 3 is arranged on the main body sleeve 1. The discharge end is provided with an integrated nozzle 4, and a buffer device 5 which can slow down the speed of medicine entering the nasal cavity is arranged in the integrated nozzle 4. The traditional Chinese medicine powder of the present invention enters the integrated nozzle 4 from the main body sleeve 1 under the action of the push rod 2, and under the action of the buffer device 5, the speed of the medicine powder is effectively reduced, thereby effectively overcoming the discomfort of the patient when taking medicine.

[0027] In the first embodiment of the buffer device 5 of ...

Abstract

The invention discloses a nasal cavity suction administration device. The device comprises a main sleeve, wherein a push rod is arranged in the main sleeve, and a piston is arranged on the push rod. The device is characterized in that an integral spray head is arranged at the discharge end of the main sleeve, and a buffering device capable of reducing the speed for a drug to enter the nasal cavity is arranged in the integral spray head. The device aims to overcome the defects in the prior art and is simple in structure and convenient to use. The dedicated rotary smashing buffering device in the device can minimize fogdrops which are sprayed out and can also effectively reduce the speed and pressure of the drug entering the nasal cavity, and has a good administration effect.

Description

technical field [0001] The invention relates to a nasal cavity inhalation drug delivery device. Background technique [0002] The existing nasal cavity inhalation drug delivery device generally includes a syringe, and a nozzle is arranged at the front end of the syringe. Delivery is like in the nasal cavity, but due to design defects in the existing nasal cavity inhalation drug delivery device, the liquid dispersion effect during the drug delivery process is not good, the droplet particles are large, it is not easy to inhale the drug into the nasal cavity, and there is no spray buffer device , When the drug enters the nasal cavity, the pressure is too high, which brings discomfort to the patient. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a simple in structure and easy-to-use nasal cavity inhalation drug delivery device. While the drops are minimized, the speed and pressure when the...
