Portable dosing device for disinfectant solution

The invention relates to a portable dosing device on the arm, or on the belt or on the back of a mobile or other telephone, comprising a casing, a reservoir of disinfectant solution, a dispensing pusher mounted to slide in the casing and cooperating with a pump in communication fluidic with the tank. The device makes it possible to distribute, in a simple, rapid and effective manner, doses of disinfectant, cleaning, medicated, or other solution.

Healthcare-associated infections (HAIs) affect hundreds of millions of patients worldwide each year. These infections are the cause of serious pathologies, prolongations of the length of stay in healthcare establishments, long-term disabilities, significant personal costs for patients and their families, high additional financial burdens for healthcare systems health, and worse still, the tragic loss of life. By their very nature, infections are caused by many factors, relating in particular to healthcare systems and procedures, to human behavior conditioned by education, the economic and political constraints of systems and countries, and often by norms and societal beliefs. Many of these infections can be avoided according to the summary of WHO (World Health Organization) recommendations for hand hygiene during care, by Professor Didier PITTET, Director, Infection Control Program, Geneva University Hospitals.

Hand hygiene is the key measure to reduce infections. A simple gesture, perhaps, but the observance of which by healthcare professionals remains problematic all over the world. Various strategies for promoting and improving hand hygiene have been proposed, and the First WHO Global Patient Safety Challenge - Clean Care and Safer Care devotes some of its attention to hand hygiene. setting standards and improving hand hygiene practices alongside the implementation of useful interventions according to the reference cited above.

Still according to the same reference, in developed countries, IAS concern 5 to 15% of hospitalized patients and can affect 9 to 37% of patients admitted to intensive care units.

Following contact with patients and/or a contaminated environment, microorganisms can survive on the hands for varying periods of time (from 2 to 60 minutes). The hands of caregivers gradually become colonized with commensal bacterial flora and with potentially pathogenic agents during patient care. In the absence of hand hygiene practice, the degree of hand contamination increases with the duration of care according to the reference cited above.

While it has been shown that hand hygiene is the essential measure to prevent HAIs and the development of antimicrobial resistance, it has also been shown that healthcare workers encounter difficulties in observing hand hygiene. , at different levels according to the reference cited above.

In addition, during an epidemic or pandemic, the needs in terms of hand hygiene are particularly important both for the general public and for employees exercising essential professions such as caregivers, traders in the food sectors, etc. .

WHO has issued the following consensus recommendations:

Hand rubbing with a hydroalcoholic product is the method of choice for hand antisepsis.

Perform hand hygiene as frequently as possible.

Duration of the procedure 20-30 seconds. A shorter duration is insufficient for proper cleaning. A longer duration discourages the nursing staff and consequently reduces the frequency of cleanings.

Manufacturers of hydroalcoholic solutions also present recommendations:

Minimum quantity per friction: Typically 1 to 3 ml, in the palm of the hand. A smaller amount reduces cleaning efficiency. A larger amount increases the cost of the procedure and therefore may tempt users to reduce its frequency.

There are pen-shaped devices on the market that allow you to carry a cleaning solution, but the quantity remains limited, allowing only 2 to 3 hand rubs. These devices also do not allow control of the volume of solution per procedure.

An insufficient quantity does not allow a complete treatment of the hands. Too much of it leads to wastage of the product and possible leakage of the product from the hands (risk of damage to surrounding objects).

Devices that are worn on the wrist are also known, making it possible to deliver a dose of solution. Some devices have a flexible box serving as a reservoir. By pressing on the casing, it deforms and causes the solution to be expelled through an outlet orifice. This type of device is inexpensive but does not allow the quantities delivered to be measured. Additionally, users have a natural tendency to press for a long time, delivering large doses, which helps empty the reservoir very quickly, and delivering a very low number of doses. The user is thus forced to fill his device at a high frequency, at short time intervals.

Other boxes use a pump with a dispensing button. The document US20200268217 illustrates this type of device. The pump cooperates with a tank and the button, accessible from the outside of the case, allows to deliver a dose of solution. The pumps used for these devices are cylindrical in shape with a small diameter. To allow a sufficient quantity of solution to be dosed, the length of the pump is important. This great length means providing a case that is also very long, to the detriment of user comfort and ergonomics.

Otherwise, to obtain sufficient doses, the user must press the push button several times.

There is therefore a need for a device making it possible to facilitate the disinfection and/or cleaning of the hands of nursing staff so as to allow cleaning in all circumstances, as soon as necessary, with controlled quantities of solution.

To do this, the invention provides a portable dosing device comprising a housing, a reservoir of disinfectant solution, a dispenser pusher mounted to slide in a pusher body cooperating with a pump itself in fluid communication with the reservoir, in which the body pusher has a profile whose width a is greater than the height b.

Advantageously, at least a portion of the distributor pusher, sliding in the pusher body, has a profile corresponding to that of the pusher body.

According to an advantageous embodiment, the pusher body has an oblong profile.

According to another advantageous embodiment, the box has a parallelepiped shape.

This architecture makes it possible to obtain a very compact and ergonomic portable device. More particularly, the casing may have restricted length dimensions, limiting the size. This is particularly advantageous when the device is worn in bracelet mode.

The device represents an important practical advantage because the bracelet is always on the wearer. For example, during treatment, it is possible to disinfect your hands by avoiding moving to reach a bottle of disinfectant solution, thus avoiding interrupting treatment in progress. The dosing tank allows you to use the exact amount of solution required to be effective. As a result, the risk of waste or conversely, the risk of underdosing are eliminated. The storage tank makes it possible to have a reasonable number of doses without having to refill it inadvertently.

According to an advantageous embodiment, the pump and the pusher body define a volume V of calibrated dosage of disinfectant solution. This characteristic makes it possible to provide a calibrated dosage, for example according to the health recommendations of organizations such as the WHO. The calibrated dosage avoids under-dosing which would make the disinfectant less effective, or over-dosing which wastes the solution and reduces the number of doses of the device.

Advantageously, the free end of the pump forms an angled suction channel directed towards the tank. This feature makes it possible to reduce the length dimensions of the device and facilitates fluid communication with the reservoir.

According to another advantageous embodiment, the housing comprising an axis or median plane M-M, the dispenser pusher, the pusher body and the pump are arranged above said axis M-M.

Advantageously, the portable metering device comprises a base, the housing can be removably mounted on the base, said base having side edges rising and extending towards the central axis M-M of the housing. This characteristic makes it possible to design a base whose side edges provide good support for the case. This also allows the user to place the case on its base or remove it in one quick and easy step. The user does not have to remove the base from the wrist or even remove the bracelet.

We also observe that the volume V is located above the M-M axis.

Also advantageously, the box can be inserted into the base according to a plurality of positions angularly spaced by 90°. This characteristic makes it possible to position the box so that the dispenser pusher is oriented in a position that is always ergonomic according to the needs and wishes of the user.

The metering device can preferably be used to dispense calibrated doses of disinfectant, medicated, cleansing, moisturizing or other solution.

According to yet another variant embodiment, the base forms a clamp releasing a slot. This embodiment allows use with a mobile phone stored in a pocket and the metering device positioned outside the pocket, ready for use.
