DESCRIPTION

Single-dose and disposable preloaded device for the application of products in vaginal or rectal cavity.

Technical sector

The present utility model is designed for use in the pharmaceutical and cosmetic sector for the application in the vaginal or anal cavity of any living being of products in any physical state of matter, by means of a mono-dose device, pre-loaded and disposable.

Background of the invention

Currently the existing administration formulas consist of the use of 15 rechargeable / reusable cannulas, digital self-administration or the use of single-dose tubes with nozzle. The lack of hygiene in the application and the risk of associated infection are the inefficiency in the administration of the product and the inefficiency in the application of the product since in many cases a significant part of the product is trapped in the device. There are instruments with similar objectives to the one proposed. However, either because of its complexity or cost, they are not available for large consumption or offer the features, benefits and advantages of the utility model presented below. Examples of such instruments can be found below:

Explanation of the invention.

The purpose of this device is to offer a response to the absence of disposable and preloaded devices for the application of vaginal or anal products aimed at mass consumption. It provides greater hygiene, comfort, effectiveness and efficiency in the administration of the products (estrogenic creams, antifungal, spermicides, lubricants, repitalizing etc.). It is designed in such a way that it allows to democratize its access and generalize its use. The idea arises from the user experience that confirms this supply gap in the market when it comes to satisfying their own needs.

It is a pre-filled disposable device for dispensing one or more products in the vaginal and / or rectal cavity of the body of any living being. The product may be in any physical state of matter. The administration of this substance will have medical, sanitary, cosmetic, therapeutic and other objectives compatible with this method of administration. The device consists of: 5

- A cannula (1) to accommodate the product to be dispensed, the cannula can be of any length and diameter adapted to the human or animal anatomy and the purpose of its administration. It has an opening in the lower part and may have one or several holes in the upper part as well as one, several or no holes along the surface of the cannula. These holes may have any geometry and their density and / or size may be different along the cannula.

- In its lower part, the cannula may have a variation in its geometry (widening or narrowing of the diameter) and / or its surface. These 15 features allow you to easily grab the applicator and avoid sliding between the fingers. In case of narrowing, this will prevent the exit of the piston (2) in the case of an integrated piston system.

- A piston (2) that may or may not be pre-inserted (integrated) into the cannula and may or may not be telescopic depending on the length of the cannula where it is inserted. The displacement of the piston inside the cannula causes the product to exit through the hole (s) in a controlled manner. In non-pre-inserted plunger systems, the cannula will be designed for easy and convenient insertion of the plunger.

 25

- A sealing device at the bottom of the cannula whenever necessary to prevent spillage of the contents.

- Depending on the physical characteristics of the pre-filled product and the characteristics of the perforation of the cannula, it can be closed by a hood or seal 30 that ensures the perfect confinement of the product inside until the moment of administration of the product.

- The cannula, the plunger, the seal and the cap / cap may be of any material suitable for contact with the organism. 35

- The device may or may not be individually packaged for proper preservation, comfort and / or discretion for transport and use.

The advantages of the invention are listed below:

• Improves the hygiene conditions in the application, risk of contamination of the product in its handling and therefore the risk of infection in the organism in which it is inserted compared to the current application procedures.

 Four. Five

• It facilitates the administration of the product by being adapted to the physical characteristics of the user to whom it is addressed.

• Improves the effectiveness of product administration by allowing a more uniform distribution and better adapted to the treatment being sought or the area to be treated. fifty

• Improves the efficiency of the use of the product by reducing the loss or depletion of the product that is wasted by being trapped inside the existing tubes and application methods, in particular the cannulated tubes.

• The mono-dose format allows accessibility to the treatment at all times by the user since the user can transport it comfortably and discreetly while preserving its characteristics. In addition, its disposable character increases these advantages.

 Detailed statement of at least one embodiment of the invention

Two practical embodiments of the device are detailed below. The first practical embodiment of the device is for the administration of suppositories, beads or ovules. In this case the product includes:

A cannula (1) to accommodate the product to be dispensed. It has an opening at the bottom and a hole at the top where the suppository, pearls or ovules will come out. The geometry of the bottom of the cannula has a narrowing and the roughness of the material is greater to facilitate grasping the device more easily. The dimensions and length of the cannula vary depending on the user and his age.

A piston (2) pre-inserted (integrated) into the cannula (3). The displacement of the plunger inside the cannula causes the suppository, pearls or ovules to exit through the hole in the upper part.

This application increases hygiene, comfort and safety when administering these products against the digital insertion of the suppository. In this case, it can be foreseen that the cannula is commercialized pre-impregnated with some lubricant to facilitate its insertion.

The second practical embodiment of the device detailed is for the administration of vaginal lubricants. In this case the device consists of: 10

- A cannula (1) to accommodate the lubricant. It has an opening at the bottom and several holes along the surface of the cannula. The size and geometry of the holes may vary depending on the objective and the product to be administered. The density of the holes along the cannula is decreasing towards the top to ensure the exit of the product through the entire wall of the cannula.

- In its lower part, the cannula is slightly narrower to retain the pre-inserted embolus facilitating the manipulation of the device.

 twenty

- A seal on the bottom of the cannula to prevent spillage of the product.

- The cannula is covered by a seal that ensures the perfect confinement of the product inside until the time of administration.

 25

- The piston that may come pre-inserted or not in this case by way of example. It comes not integrated. It is designed for easy and convenient insertion into the cannula. The embolus breaks the seal of the bottom of the cannula and its displacement along the inside of the cannula, increases the internal pressure causing the product to escape.

 30

The set will be presented in an individual, easy-to-open package that allows convenient transportation and disposal.
