Description

Field of technology

The utility model relates to the field of medical technology, namely to the packaging and distribution of liquid medicinal forms in sterile form.

State of the art

A dropper bottle for liquid dosage forms is known, comprising a hollow vessel for filling it with a medicinal liquid, a dropper spout with a channel, rigidly connected to the vessel, the dropper spout has an annular flange for reliable sealing, while at least part of the outer surface of the dropper spout and the annular flange are coated with a layer of silver [RU Patent for Utility Model No. 168297. IPC B05 B11/04. Published on 21.01.2017]. Disadvantages of the known device: complexity of the design, the need for silver coating.

A nozzle is known for installation on a bottle with a medicinal liquid, comprising a hollow cylindrical body, the first end of which is made with an opening and the possibility of connection with the bottle, and the second end is made integral with the spout, characterized in that the second end of the body is made blind, and the spout is installed at an angle to the base located between the cylindrical wall of the body and the second end, wherein the part of the second end not aligned with the base of the spout is made elastically flexible, and the entire remaining surface of the body is inflexible [Russian Federation patent for invention No. 2039539. IPC B05 B11/04. Published on 20.07.1995]. Disadvantages of the known device: complexity of the design.

A container for storing a liquid subject to drip dosing is known, comprising a reservoir with a wall made with the possibility of manual deformation for dispensing the liquid (1) by pressing on the wall (2), and a dispensing head (3) having a hollow body (4) provided with a spout (5) for dispensing the liquid (1), and a hydrophobic microporous plug (8) located behind the reservoir, wherein the container itself is provided with a removable cap (6) for hermetically sealing the spout (5), which, in combination with the hydrophobic microporous plug (8), prevents the spontaneous outflow of the liquid (1) from the volume (15) of the container intended for storing it, towards the spout (5), which, firstly, prevents the spontaneous outflow of the liquid (1) through the microporous plug (8), when the cap (6) hermetically seals the spout (5), and, secondly, ensures the free outflow of the liquid (1) from the volume (15) of the container intended for storing it, through this hydrophobic microporous plug (8), when the spout (5) is open for dispensing the required portion of liquid (1) by pressing on the wall (2) of the container, characterized in that the wall of the reservoir is designed with the possibility of reversible deformation as a result of air suction inside the container (2) with subsequent spontaneous return of the container to its original shape after dispensing the liquid (1), wherein the removable cap is designed with the possibility of airtight closure of the spout, wherein the hydrophobic microporous plug (8), in the case when the cap is open, provides the possibility of passing the sucked air into the specified volume (15) for storage due to the elastic return of the wall (2) of the container to its original shape, which occurs after dispensing a portion of the liquid (1), wherein the body (4) of the dispensing head is installed inside the neck (10) motionlessly, and in front of the spout (5) there is an antibacterial filter membrane (7), containing a hydrophilic part, providing the possibility of passing liquid through itself under the action of excess pressure created in the container when pressing on its wall, and a hydrophobic part that allows air to pass through itself under the action of a vacuum that occurs when pressing on its wall is stopped [RU Patent for Invention No. 2385774. IPC B05 B11/04. Published on 27.07.2008]. Disadvantages of the known device: complexity of the design.

Disclosure of the essence of the utility model

The objective of the utility model is to develop a preservative-free system that ensures long-term effectiveness of the drug.

The technical result of the utility model consists in eliminating the accumulation of pathogenic microflora in a bottle with a medicine.

The vial for medicinal liquid contains: a body equipped with a cap; a cartridge equipped with a microporous filter, a membrane with a porosity of 0.2 µm and a spout equipped with a mark.

A cartridge in the form of a cylindrical body is installed inside the body. The cartridge is equipped with a spout, a microporous filter and an antimicrobial membrane located between the cartridge and the spout. There is a mark in the form of a color indicator on the spout. A cap is put on the spout, which can be connected to the body using a threaded or groove connection. The cap protects against the accumulation of pathogenic microflora on the spout.

Making the membrane porosity 0.1 µm or less will make it difficult to completely wash it from pathogenic microflora. Making the membrane porosity more than 0.2 µm will allow pathogenic microflora to get into the medicinal liquid through the spout.

The removable cartridge allows you to remove it from the device body to rinse the microporous filter and antimicrobial membrane under water, cleaning them from accumulated pathogenic microflora. The color indicator located on the spout changes color after the cartridge is rinsed with the required amount of water.

Implementation of a utility model

Example #1

The medicinal liquid is poured into the housing of the utility model. A cartridge with a filter of 0.03 μm porosity is inserted into the housing, the filter is covered with a membrane with a porosity of 0.2 μm on top. The spout located in the cartridge is covered with a cap on top. When using the bottle, the cap is removed from the housing. The spout is brought to the eye, focusing on the risk located on the spout so that the tip of the spout does not touch the surface of the eye. Press on the housing of the device and squeeze the medicinal liquid into the user's eye. If pathogenic microflora gets into the spout of the device, the membrane and microporous filter located in the cartridge retain the pathogenic microflora. Then the cartridge is pulled out of the housing and washed under running water until the indicator located on the spout changes color.

Example #2

The medicinal liquid is poured into the housing of the utility model. A cartridge with a filter of 0.05 μm porosity is inserted into the housing, the filter is covered with a membrane with a porosity of 0.2 μm on top. The spout located in the cartridge is covered with a cap on top. When using the bottle, the cap is twisted off the housing. The spout is brought to the eye, focusing on the convex ring located on the spout so that the tip of the spout does not touch the surface of the eye. Press on the housing of the device and squeeze the medicinal liquid into the user's eye. If pathogenic microflora gets into the spout of the device, the membrane and microporous filter located in the cartridge retain the pathogenic microflora. Then the cartridge is pulled out of the housing and washed under running water until the indicator located on the spout changes color.

Claims (1)
