Abstract

The novel disinfecting device for use in hospital drainage tubes efficiently sterilizes both the catheter and drainage bag while reducing the risk of infection to the patient. Disinfection is performed using at least one ultraviolet light and/or ozone-generating lamp that irradiates by means of a removable device which is external to the catheter, from which said radiation is transferred to the patient and/or to the drainage bag. The tube is made of light-conducting plastic. In some versions, the light source irradiates from inside the catheter, the device being inserted in a connection valve of the tube; in another version, the light source is integrated in the material of the tube. For use in the hospital sector.

Description

 Title: Device for application disinfection in hospital drainage probes.

Object of the invention

Usually one of the complications that may arise from hospital catheters or drains, especially in bladder catheterization, are infections, to avoid these, aseptic measures are extreme in the patient's environment; it would be desirable, then, to have a method and device that would contribute to the elimination of these problems, without also supposing a substantial modification of the usual operation in the placement of the boreholes.

The device for disinfection for application in hospital drainage probes of the present invention uses a source of ultraviolet and / or ozone generating radiation as a sterilization measure, radiating with at least one source of ultraviolet and / or ozone generating light (1 ) on the probe (2) (figure 1) transmitting this radiation to the patient and / or to the drainage bag (6) at its most distal end (figure 2), the constituent material of the probe being plastic with luminoconductive properties, in this way the risks of infection in the patient are minimized, also avoiding the possible risk of contagion by the health personnel when this material is handled.

The invention has the advantage of being a non-invasive and removable method, that is, the device can be applied and removed simply without having to alter the current drainage procedures. It has the advantage of constituting a recoverable device, after its application, it will be removed and can be reused again.

The disinfection device for application in hospital drainage probes comprises at least one source of ultraviolet and / or ozone generating radiation (1), and can be integrated in a portable device (3) powered by batteries (4) and its corresponding power switch. drive (5) (figure 1), or said light source and its external power supply (7) (figure 3), guiding said light source through a probe of a lumm ^'or conductive nature (8) to the element (9) contact with the probe, which will have an inner surface (10) (Figures 3 and 4) in contact with it, of a luminoconductive nature and therefore transmitter of ultraviolet light radiation and / or ozone generator.

The radiation surface will have a geometry of adaptation to the probe that maximizes the contact between both bodies, for example, in the case that we select the contact point of the luminoconducting device in the catheter (figures 3 and 4), the device will be installed comfortably on said catheter being fixed on it firmly by means of a clamp type element (9) (figure 3), or by another type of mechanical or adhesive retention of conventional use, which can be removed after application. Versions are provided in which by inserting an opaque connector to this radiation into the catheter (11) (figure 5) or by introducing a discontinuity in the luminoconductive nature of the catheter (12) it is possible to radiate to the patient or to the drainage bag Figures 7 and 8), or both ways (Figure 6) depending on how we place the radiation emitting element (3) fixed in one of the sectorized sections or covering both.

Versions are planned in which ultraviolet and / or ozone generating radiation is not carried out from outside the probe as in the typology described above, but this radiation emanates from inside the catheter by means of an emitting device (13) ( Figures 9 and 10) which will contain at least one ultraviolet and / or ozone generating source (1), its power supply and its conventional switching circuit. Said emitting device will penetrate the connection valve (14) of the probe, radiating from inside. Alternatively versions are planned in which the source of emission of ultraviolet light and / or ozone generator is housed in an external device (7) (figure 10), which has a fiber of light-conducting nature (8), which will guide said light source penetrating the connection valve (14) (figure 10) of the probe.

Versions are provided (figure 1) in which the ultraviolet light emitter and / or ozone generator (1) is integrated in the plastic constitution of the probe itself, equipped with its relevant power cable (15) to a source conventional power supply, maintaining the other characteristics of the probe, its drainage hole (16) and inflation duct (17) of the bladder balloon (18), in the case of urinary probes. Unlike the previous versions described, this device is not recoverable for hygienic reasons, since it is integrated in each of the probes since its manufacture, and is not an external as in the previous cases.

Background of the invention

In order to sterilize the probing and / or drainage bags that are usually used in hospitals, the state of the art shows different solutions as in WO 84/04036 of BAXTER TRAVENOL LABORATORIES, INC, which introduces a chemical effect composition antimicrobials inside the drainage bag, in this case urinary.

There are no known probes and / or hospital drainage that incorporate sterilization devices by ultraviolet radiation.

In this preferred embodiment, the device for disinfection of application in hospital drainage probes is described, this probe will be made of luminoconductive material whose property has been achieved, for example, by coating the constituent material of the probe with a plastic polymer with a refractive index different. The light radiation is transmitted along the probe to the drainage bag and the patient.

The activation of the ultraviolet radiation device and / or ozone generator for disinfection of urinary genito pathways will be carried out by means of a switch drive (5), or a timed circuit that sets the operating periods at the discretion of the physician.

The materials, shape, size and arrangement of the elements will be subject to variation as long as this does not imply an alteration of the essential features of the invention, which is claimed in this preferred claim mode.
