Abstract
The utility model relates to the technical field of inhalation preparation production equipment, in particular to an inhalation preparation pre-spraying device for clinical tests, which comprises a collecting bottle, a vacuum pump, a conduit and a pre-spraying bottle; the collecting bottle comprises a bottle body and a bottle cap, a solvent is contained in the bottle body, and the bottle cap is connected with the vacuum pump; the pre-spraying bottle is horizontally arranged, one end of the pre-spraying bottle is in an open shape, the other end of the pre-spraying bottle is provided with a cover body, a guide pipe is connected onto the cover body, and the other end of the guide pipe penetrates through the bottle cap and extends into the solvent. The utility model generates suction force through air back-suction, so that atomized liquid medicine sprayed forwards can not rebound, and the back-suction is dissolved in the solvent, thereby effectively avoiding pollution; the pre-spraying bottles of different types are replaced according to the spraying range of the mist liquid medicine, and the operation is convenient.
Description
Technical Field
The utility model relates to an inhale preparation production facility technical field, concretely relates to inhale preparation and spout device in advance for clinical trial.
Background
In phase I clinical trials of inhaled formulations, a pilot spray was performed prior to each dose to confirm proper device spray. To prevent contamination, inhalation formulation tests are generally conducted in a fume hood with a plastic bag, conical flask or other container to collect the sprayed liquid, thereby reducing environmental and space contamination. But atomized liquid medicine rebounds when encountering resistance, so that the possibility of polluting an inhalation preparation device exists, the device pollution can influence the administration accuracy, and indirect contact pollution can also be caused to influence experimental data; the collection containers are limited in space, each device is pre-sprayed to require replacement with a new container to avoid cross-contamination, multiple containers are required for collection, and operation is extremely inconvenient.
Disclosure of Invention
The utility model aims at solving the above problem, providing a inhale preparation and spout device in advance for clinical trial, can be used for avoiding the pollution that the liquid medicine produced after spraying, easy operation, convenience.
According to the technical scheme of the utility model, the inhalation preparation pre-spraying device for clinical test comprises a collecting bottle, a vacuum pump, a conduit and a pre-spraying bottle; the collecting bottle comprises a bottle body and a bottle cap, a solvent is contained in the bottle body, and the bottle cap is connected with the vacuum pump; the pre-spraying bottle is horizontally arranged, one end of the pre-spraying bottle is in an open shape, the other end of the pre-spraying bottle is provided with a cover body, a guide pipe is connected onto the cover body, and the other end of the guide pipe penetrates through the bottle cap and extends into the solvent.
Further, the pre-spraying bottle is connected with the cover body through threads.
Further, the conduit is a transparent hose.
The beneficial effects of the utility model reside in that: suction is generated by air back-pumping, so that atomized liquid medicine sprayed forwards cannot rebound, and the liquid medicine is dissolved in the solvent by the recovery force, so that pollution is effectively avoided; in addition, the pre-spraying bottles with different volumes are replaced according to the spraying range and the spraying length of the mist liquid medicine, so that the operation is convenient.

Description of reference numerals: 1-collecting bottle, 1.1-bottle body, 1.2-bottle cap, 1.3-solvent, 2-vacuum pump, 3-conduit, 4-pre-spraying bottle and 4.1-cover body.
Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in the figure: an inhalation preparation pre-spraying device for clinical trials comprises a collecting bottle 1, a vacuum pump 2, a conduit 3 and a pre-spraying bottle 4. The collecting bottle 1 comprises a bottle body 1.1 and a bottle cap 1.2, wherein the bottle body 1.1 contains a solvent 1.3, and the solvent 1.3 is selected according to the pre-sprayed inhalation preparation and can be water or an organic solvent or a mixture of water and an organic solvent, and the main reference is the solubility of the medicine. The bottle cap 1.2 is connected with the vacuum pump 2 and used for generating negative pressure in the bottle body 1.1. One end of the pre-spraying bottle 4 is open and is used for sucking the preparation liquid medicine for pre-spraying, the other end of the pre-spraying bottle 4 is provided with a cover body 4.1, and the pre-spraying bottle 4 is horizontally arranged to prevent the sprayed liquid medicine from dripping or gathering at the end of the cover body 4.1 along the bottle wall. The cover body 4.1 is connected with a conduit 3, and the other end of the conduit 3 penetrates through the bottle cover 1.2 and extends into the solvent 1.3.
Specifically, spout bottle 4 in advance and lid 4.1 pass through threaded connection, simple to operate, the change of being convenient for spouts bottle 4 in advance. The conduit 3 is a transparent hose, which is convenient for installation and observation of whether the liquid medicine remains in the conduit.
The utility model has simple structure and convenient operation, can be used for the pre-spraying operation of the inhalation preparation aerosol device in clinical tests (also pre-spraying according to the specification requirements), finds the problem of the preparation device in advance and ensures that the inhalation preparation aerosol device can be used in clinical tests; the sprayed atomized liquid medicine is sucked back and dissolved, so that the pollution to the environment and the inhalation device is avoided; aiming at different inhalation preparation clinical tests, only the pre-spraying bottle needs to be replaced, the operation is simple, the cleaning agent can be repeatedly used, and the cost is low.
