Description

Title of the invention: Syringe container adapter, syringe adapter cap and corresponding container

[0001] The present invention relates to a physiological saline (0.9% NaCl) bottle with a double closure. It comprises an internal stopper allowing for the safe withdrawal of the solution using a standard 10 ml syringe, such as those commonly used commercially for nasal irrigation, and a standard screw cap.

[0002] This innovation allows for the direct withdrawal of physiological saline solution through a stopper, particularly for nasal irrigation, while minimizing the risk of solution contamination and facilitating nasal syringe filling for the operator. Furthermore, the stopper is equipped with a small valve ensuring a double seal of the solution to prevent any unwanted leakage.

[0003] The scope of application of this innovation relates to the healthcare sector in general. Indeed, the product is specifically designed for nasal irrigation of adults, children, and babies from 6 months of age. It is important to emphasize that this product is not intended for use in filling a syringe with saline solution for injection or infusion to treat dehydration or sodium depletion.

[0004] Objectives: - avoid the risk of contamination of the physiological saline; - to facilitate the filling of 10 ml nasal syringes; - prevent the solution from spilling during nasal irrigation or transport of the solution; - perform a nasal wash safely; - Avoid waste.

[0005] Indeed, most users are accustomed to drawing the saline solution directly from the bottle or a cup, which often results in contamination of the solution by the nasal tip of the syringe, thus increasing the risk of contamination for the child. Thanks to the use of the bottle with the cap according to the invention, this contact between the nasal tip and the solution is avoided, as the nasal tip must be removed to safely draw up the solution.

[0006] Furthermore, the cap allows for the precise dispensing of 10 ml of solution, without waste. This innovation eliminates the need to transfer the solution into a cup for dispensing, ensuring that the solution remains in the bottle throughout its use, thus preserving its sterility. Unlike bottles traditional methods where it is impossible to draw the solution when the level is too low for the syringe to reach the bottom, our invention allows the solution to be drawn regardless of the bottle's capacity.

[0007] Young children may be restless during nasal irrigation, which can cause the saline bottle to tip over. The double flap of the cap according to the invention allows the bottle to be easily closed between irrigation of both nostrils, thus preventing any leakage of the solution.

[0008] Historically, nasal irrigation was performed using 5ml single-dose vials. In recent years, a new irrigation method using a nasal syringe has been recommended by healthcare professionals, allowing for more effective irrigation and preventing contamination. Consequently, some manufacturers who marketed NaCl bottles for wound irrigation took advantage of this trend to sell bottles for nasal irrigation; however, these bottles were not suitable for this purpose.

[0009] Currently, there are conventional bottles of physiological saline solution, but they are not marketed for nasal irrigation, with the exception of L2N, which came onto the market later, but none of them allow direct sampling from the bottle: - B Braun; - Fresenius; - Ground worm; - L2n; - Evolupharm: this bottle has a small cup for transferring the solution and then taking a sample.

[0010] No bottle allows direct withdrawal of the entire physiological serum from the bottle while respecting the rules of non-contamination of the solution.

[0011] Finally, there are bottle and enteral syringe adapters for withdrawing medications or enteral feeding fluids from a bottle. These devices are specifically designed for enteral syringes, which have a larger diameter than commercially available nasal syringes. The specific design of these adapters precludes their use for withdrawing physiological saline solution using standard 10 ml syringes. Previous technique

[0012] - Evolupharm bottle; - b) Compared to other bottles, the one marketed by Evolupharm has a small pouring cup integrated into the outer cap. The addition of this feature, compared to other bottles, allows for pouring the solution directly into this small cup. However, this raises two major problems: firstly, users could still draw up the solution using the syringe and its nasal tip, then return it to the bottle, contaminating the remaining saline solution in the cup. Secondly, most users are already accustomed to pouring the solution into a container larger than the volume in the cap, as this allows them to draw up more than one dose with a syringe; - c) The stopper according to the invention requires the user to remove the nasal tip in contact with the nasal mucosa when drawing up the physiological saline solution, thus eliminating any risk of contamination of the solution. It is not necessary to transfer the solution into another container to draw up the entire contents of the bottle, which helps prevent contamination and waste;

[0013] A container adapter for a syringe is proposed, comprising a main body shaped to fit forcefully into an opening in the container and a through hole, formed in the main body, for the insertion of a dosing syringe tip, characterized in that it comprises a cap, integral with the main body, having a pin for forceful insertion into the through hole to seal it hermetically.

[0014] Optionally, the cap includes a circular base forming a lid, in the center of which the insertion pin extends in a direction essentially normal to this circular base.

[0015] Optionally, the cap and the main body are connected to each other by a ribbon, the whole being made from material by molding.

[0016] A syringe adapter cap is also proposed, intended to seal an opening in a container, this opening being cylindrical in cross-section with external threads, the cap comprising: - a first inner plug in the form of an adapter according to the invention; - a second external cap with internal threading intended to cooperate with the external threading of the container opening.

[0017] A container for holding a liquid to be taken by syringe is also proposed, comprising an opening and an adapter according to the invention, or a cap with an adapter according to the invention.

[0018] Technical specifications: - a) The stopper according to the invention is a device which has been designed so that it can be inserted optimally into the bottle but also by providing it with a slight curvature allowing optimal withdrawal of the saline solution thus avoiding leaks. - b) The stopper according to the invention allows for extemporaneous sampling of the saline solution using a 10ml syringe. It is equipped with a small flap allowing for double closure and enabling closure with one hand. - c) Currently, no stopper or bottle allows for direct withdrawal of the solution using a standard 10 ml syringe. The stopper in question is specifically designed with dimensions and shape adapted to facilitate syringe insertion without any leakage of the solution. It also ensures easy closure during use and a double seal (flip + bottle cap) during transport to prevent any leakage of the solution. - d) The physiological saline bottle fitted with the stopper according to the invention is the only one that allows the physiological saline solution to be withdrawn from the bottle and guarantees the absence of contamination of the solution. The stopper according to the invention has specific design and dimensional characteristics to allow the solution to be withdrawn with a 10 ml syringe.

[0019] Technical advantages of the invention: - Sampling directly from the bottle, - Insertion of a syringe via the cap without difficulty or leakage (syringe / bottle seal) - No possibility of contact between the solution and the nasal tip of the syringe, - Double-valve closure to prevent the risk of solution leakage during use or transport, - Reduced solution waste: ability to collect every last drop

[0020] There is no commercially available device that allows for the filling of a nasal syringe without transferring the solution to another container and without ensuring that the user cannot draw up the solution with the syringe's nasal tip in direct contact with the nasal mucosa. Nasal hygiene is essential to prevent ENT infections; improper use could lead to user contamination. The significant advantage of the cap according to the invention is that this device forces the user to remove the nasal tip from the syringe, whereas currently very few users do so. This is a way to ensure mandatory safe withdrawal.

[0021] Applications studied or potential industrial application areas: pharmaceutical and health / hygiene sector. Pharmaceutical industry, pharmaceutical wholesaler, pharmacy.

[0023] The physiological saline bottle is made of transparent PET with a capacity of 500ml (polyethylene terephthalate), cylindrical in shape, and with a threaded neck with a diameter of 22mm).

[0024] The objective of our bottle is to incorporate a stopper according to the invention allowing the solution to be withdrawn with a standard 10 ml syringe while ensuring a seal between the bottle stopper and the syringe, thus preventing any leakage.

[0025] Regarding the stopper, it is first necessary to define the diameter of the hole suitable for the 10 ml syringe. We first measured the diameter of the tip of the syringe. We decided to make the hole very slightly smaller at 4mm to guarantee no leakage between the bottle and the syringe.

[0026] To facilitate the insertion of the syringe, we decided to slightly curve the stopper (see [Fig.1]).

[0027] The cap according to the invention is transparent, made of PP, and has the following characteristics: Height: 12.4 mm; maximum diameter: 24.7 mm; hole diameter: 4 mm; valve diameter: and with a piston height: 8.1 mm
