Definitions

• This patent relates to medical devices for cryotherapy in the treatment of skin lesions and warts and in particular concerns a new dispensing device for pressurized containers for the application of cryogenic coolant.
• Cryotherapy is a therapeutic procedure that uses fluids at extremely low temperatures for the localized treatment of skin lesions such as warts or other more or less serious skin diseases.
• the controlled and precise application of the cooling fluid on the lesion leads to the freezing of intracellular water and the alteration of proteins and enzymes, causing, in the therapeutic application and subsequent defrosting time, dermo- epidermal detachment without damage to the dermis.
• cryotherapy The advantages of cryotherapy are numerous. Firstly, anaesthesia of the area to be treated is not usually required and in addition, in most cases, scars do not appear and complex postoperative medications or treatments are not necessary.
• the cooling fluid to be used in cryotherapy is stored in pressurized containers with spray type dispensers with an opening/closing pressure valve.
• the known containers also comprise a removable tube or duct for application, at the end of which an applicator pad or swab suited to absorb and convey the coolant coming out of the container is placed.
• the applicator pad or swab soaked in the cooling fluid is applied to the part to be treated, which is thus frozen, causing the rupture of the cell membranes and the subsequent dermo-epidermal detachment.
• the tube or duct is applied to the container's dispenser in a removable manner at the time of use, that is, the user must first of all apply the tube, then place the applicator pad and finally dispense and apply the fluid.
• One of the drawbacks of the known devices is the fact that the uncontrolled release of the cooling fluid may occur, for example during the application or removal of the tube, resulting in a waste of material and, above all, the possibility of causing wounds and injuries to the user or the patient.
• the operator must act quickly from the time the cooling fluid is dispensed to the time of application, to avoid an excessive change in the temperature of the fluid compared to the optimal values thereby reducing the effectiveness of the treatment.
• the main object of the present invention is to be able to be used with maximum safety for the operator and for the patient, because the uncontrolled release of the coolant fluid is hindered thanks to an activator cap or plug, which causes the fluid to be dispensed in an enclosed space to soak the applicator pad or filter.
• Another object of the present invention is that it can be used in a simple, fast and immediate manner because the tube or duct to dispense the cooling fluid is integrated and integral with the dispenser body and therefore it is not necessary to assemble the tube ahead of time which inevitably results in a loss of time and the possible uncontrolled release of fluid.
• Yet another object of the present invention is to speed up the application procedure, thereby also minimizing the variation of the fluid temperature before its application on the skin and thus increasing the efficiency of the cryotherapy, to the benefit of the patient.
• Another advantage of the present invention is that the operator is able to identify with certainty and timeliness the moment in which the applicator pad or filter is adequately soaked with coolant fluid and therefore ready for immediate application.
• a further advantage is the fact that it is made with materials having suitable mechanical and chemical resistance to the substances used, as well as resistant to the low temperatures.
• the new dispensing device for pressurized containers with a dispensing pressure valve for the application of cryogenic coolant gas in cryotherapy treatment comprising a dispenser body with an integrated and integral tube, in which a cylindrical removable application pad or filter is partially inserted, suited to absorb and conduct the cooling fluid, and where a safety activator cap or plug is suited to close the dispenser body, preventing the accidental release of the fluid, and also to open the valve, leading to the controlled delivery of the fluid, which, conveyed through the tube, is immediately absorbed by the pad or filter.
• the activator cap comprises a casing suited to close the dispenser body, to which it is rigidly coupled in a removable manner, and an internal channel, integral with the upper internal part of the cap, suited to house the tube or duct of the dispenser body.
• the cylindrical wall of the internal duct of the cap comprises, on the lower edge, one or more teeth or projections suitable to be inserted into corresponding slots or through holes on the dispenser body.
• the cap To dispense the fluid, the cap must be correctly positioned on the container and the container inverted, orienting it with the cap facing downwards.
• valve-opening element an element positioned between the dispenser body and the upper edge of the container, connected to the container's valve.
• valve- opening element The pressure applied on the valve- opening element, with the container inverted, causes the valve to open and, as a result of the force of gravity in addition to the pressure of the fluid in the pressurized container, results in the flow of fluid through the tube or duct integral with the dispenser body.
• the pad or filter partially inserted inside the tube absorbs the fluid and draws it up to the top, becoming completely soaked in the fluid.
• the fluid flows out more rapidly, thereby considerably reducing the time needed for the complete soaking of the pad or filter.
• the pad or filter is made of cellulose or open cell foam, preferably polyurethane S518.
• the internal duct of the cap which completely contains the tube, keeps the inserted pad or filter in the correct position, preventing it from being expelled due to the pressure of the gas.
• This cap or plug is made of plastic material, having suitable mechanical, chemical and thermal resistance characteristics, and preferably transparent, so that the user, having activated the cap causing the fluid to be dispensed, can see from the outside whether the pad is soaked and if it is then ready to be used. In fact, the flow of fluid and its absorption by the pad causes the deposition of condensate on the inner surface of the cap next to the pad itself, thus making it clear that the pad is soaked and ready for use.
• ribs and/or grooves for the proper alignment and positioning of the cap.
• the cap can be aligned and positioned on the dispenser body in two different positions. In the closed “OFF" position the cap inserted on the dispenser body is rotated so that the teeth do not fit into the corresponding slots formed on the dispenser body and therefore it is not possible to trigger the dispensing of the fluid.
• the cap In the activated "ON” position, the cap is rotated for example by 180° relative to the closed “OFF” position, so that the teeth are aligned with the slots, therefore the user can, by pressing the cap towards the container, insert the teeth in the slots and act on the valve-opening element causing the fluid to be dispensed.
• Figure 4a shows a three-dimensional view of the activator cap (T), while
• Figures 4b-4e show respectively a side view, a section, a bottom view and a top view.
• FIGs 5a-5b schematically show the operation of the activator cap (T), which is shown in the closed “OFF” position in Figure 5a and in the activated “ON” position in Figure 5b.
• Figures 5c-5e schematically show the cap (A) in section inserted on the dispenser body (A) in the different closed and activated positions.
• the new dispensing device is applicable in an integral manner on pressurized containers (C) with a pressure valve (CI), of the spray type and comprising a dispenser body (A) suited to be fixed to the container (C).
• the dispenser body (A) comprises a cup-shaped or convex part (A2) suited to contain the upper end of the container and at least one tube or duct (Al) integrated and integral with the cup- shaped part (A2), for the flow of cooling fluid stored in the container (C).
• Said tube (Al) is internally shaped or comprises ribs (Al l) to hold at least one cylindrical pad or filter (S) partially inserted therein and shown in Figures 5c- 5e.
• the cylindrical pad or filter (S) is made of polyurethane
• valve-opening element B
• Figures 2a- 2c Between the dispenser body (A) and the container (C) there is an interposed and fixed valve-opening element (B) shown in Figures 2a- 2c.
• the new dispensing device also comprises at least one activator cap or plug (T), shown schematically in Figures 4a-4e, comprising a casing (Tl) suited to close the dispenser body (A), to which it is rigidly coupled in a removable manner, and an inner channel (T2), integral with the upper part of the cap (T), suited to house the tube (Al) of the dispenser body (A).
• activator cap or plug shown schematically in Figures 4a-4e, comprising a casing (Tl) suited to close the dispenser body (A), to which it is rigidly coupled in a removable manner, and an inner channel (T2), integral with the upper part of the cap (T), suited to house the tube (Al) of the dispenser body (A).
• the cylindrical wall of said inner channel (T2) of the cap (T) comprises, on the lower edge, one or more teeth or projections (T21) suited to be inserted into corresponding slots or through holes (A21) formed on the cup-shaped part (A2) of the dispenser body (A), so as to rest on part (B3) of the valve-opening element (B), causing the opening of the valve (CI) of the container (C), shown in detail in Figure 3, and thus the delivery of the fluid.
• the fluid can only be dispensed with the container (C) inverted, that is with the cap (T) facing downward, and therefore the dispensing occurs, upon activation of the cap (T), as a result of the force of gravity and the pressure inside the container (C).
• the fluid flow and its absorption by the pad (S) causes the deposition of condensate on the inner surface of the cap (T), near the upper part (T22) next to the pad (S) itself, thus making it clear to the user that the pad is soaked.
• the cap can be aligned and positioned on the dispenser body in two different positions.
• the closed "OFF" position Figures 5a, 5c
• the cap (T) inserted on the dispenser body is rotated so that the teeth (T21) are not aligned with the corresponding slots (A21) formed on the dispenser body (A) and therefore cannot be inserted to act on said valve-opening element (B).
• the fluid is prevented from being dispensed.
• the cap (T) is in the closed "OFF” position, therefore, the device cannot be accidentally activated, thereby preventing the improper use by children or people in general.
• the cap (T) is nonetheless bound to the dispenser body (A) and therefore also has a hygienic protection function pre- and post-use. That is, it protects the device from dust, germs and contaminants, ensuring adequate sanitary conditions until the next use.
• the cap (T) comprises on its upper part (T22) one or more ribs, protrusions or ridges in general (T61), for example arranged along a circumference with its centre coinciding with said upper part (T22) of the cap (T), suited to define a substantially plane surface (T62) for the stable support of the cap (T) on a plane surface.
• the container may be left in the inverted position, with the cap (T) downwards to facilitate the complete soaking of the pad or filter (S).
