Definitions
- the present invention relates to a method and a device for disinfecting a region, in particular a skin site of a patient.
- the outer area of the vascular access, via which the patient is connected by means of a needle and hose connection with the device for performing the extracorporeal therapy, is known as the cause of infections.
- viruses, bacteria and germs can pass from the skin surface into the vascular system of the patient.
- the skin is disinfected around the access site.
- the method comprises the following steps: a) applying an optically active substance to the region b) applying a disinfectant to the region, wherein the optically active substance and the disinfectant are formed such that the optically active substance by the Disinfectant removed from the area or the properties of the disinfectant is changed.
- a) applying an optically active substance to the region b) applying a disinfectant to the region, wherein the optically active substance and the disinfectant are formed such that the optically active substance by the Disinfectant removed from the area or the properties of the disinfectant is changed.
- the optically active substance is changed or removed by the disinfection in at least one optical property, which also includes the case that their concentration and / or amount on the area or on the skin compared to the state before the application of the disinfectant substantially is preferably reduced by at least 75%, in particular by at least 90% and more preferably by at least 99%.
- the actual disinfection removes or changes (completely or partially) the surface coating of the optically active substance, so that the optical effect has completely or essentially disappeared or changed after a successful disinfection. This can be detected and so inferred whether sufficient was disinfected or not.
- the optically active substance may be, for example, an agent having fluorescent properties.
- an agent having fluorescent properties for example, skin-compatible fluorine or a skin-compatible, fluorine-containing substance, such as e.g. a fluorine-containing coumarin compound.
- optically active is thus not limited to the range that is perceptible by the human eye, but preferably also or alternatively includes other wavelength ranges.
- the disinfectant is any substance which firstly has disinfecting properties and secondly is able to remove the optically active substance or to change its optical properties.
- alcohol or an alcoholic solution may be used as a disinfectant.
- the invention not only encompasses the actual removal of the optically active substance, but also the changes thereof. tion of the optical properties, such as the change in the frequency range of the light emitted by the optically active substance. In both cases, it can be determined whether or where the disinfectant was applied.
- light in a wavelength range of 350-450 nm is emitted to the area, causing optical emission of fluorescent light in the range of 500-530 nm.
- These values are merely exemplary values that do not limit the invention.
- the area is preferably a skin area of the patient.
- the reverse procedure according to the invention results (examination of the absence or decrease of the optical efficiency, in particular of the fluorescence).
- the perceptibility of disjointed objects increases significantly as they are illuminated against a dark background, as is known from an observation of the starry sky.
- the perceptibility of objects is comparatively low when they appear as dark objects against a light background.
- fluorescent surfaces or bright surfaces which are due to a lack of disinfection, can be better recognized in front of a non-illuminated or dark background than missing fluorescent or non-luminous surfaces against a light background.
- the optically active substance selected in such a way is that it is more noticeable in the observation or optical detection, as an area that is not provided with the optically active substance.
- optical test i. the examination of whether or to what extent the optically active substance is still present or optically active is preferably carried out by means of an optical measuring device or personified (quod visio).
- the coating containing the optically active substance is completely or largely removed or optically altered by the disinfection.
- Areas of emitted light with insufficient disinfection can be freed from germs, bacteria, viruses, etc. in a repeated disinfection step.
- a comparison of the optical properties, e.g. the fluorescence is made before and after the disinfection and it is concluded from the comparison whether the disinfection was sufficient.
- the process of disinfection comprises two steps.
- the skin area or the area of germs, dirt and skin particles is freed.
- the skin area or area is treated with virucidal and bactericidal activity.
- a certain exposure time of the disinfectant must be considered.
- the measurement of the optical properties preferably takes place after the last disinfection step.
- the optically active substance has fluorescent properties.
- the invention encompasses any other substances which have other optical properties which can be detected. The invention is thus not limited to fluorescence.
- the method is automated or at least partially automated.
- the application of the optically active substance, the application of the disinfectant and the (single or multiple) measurement of the optical properties is carried out fully automatically. If a reference measurement and a comparison with the measurement take place after the application of the disinfectant, preferably also this comparison and a comparison based on the measurement automatically.
- the present invention preferably does not include the step of puncturing the skin but ends previously, i. with the disinfection or with the check whether it has been disinfected sufficiently.
- the present invention further relates to a device for testing the disinfection of a skin area or other area of a patient, the device comprising an emitter for emitting light to the skin area and a detector for detecting light emanating from the skin area.
- the device comprises a control unit which activates the emitter and / or the detector at certain times.
- the emitter may be configured to emit light in a wavelength range of 350-450 nm.
- the detector can be designed to detect light in a wavelength range of 500-530 nm. These are exemplary values that do not limit the invention.
- the device may comprise means for applying the optically active substance and / or means for applying the disinfectant.
- a fully automatic sequence is conceivable in that the device carries out not only the optical measurement but also the application of the optically active substance and / or the disinfectant, for which purpose application means are present.
- the device has a control unit which activates the emitter and the detector after the application of the optically active substance and before the application of the disinfectant to perform a reference measurement, as well as after the application of the disinfectant.
- the device may comprise a comparison unit which compares the reference measurement with the measurement after the application of the disinfectant and emits a signal based on the comparison. If there is a sufficiently large intensity distance between the two measurements, it can be concluded that there is sufficient disinfection. In principle, it is also conceivable that the device has no such comparison unit and that no reference measurement, but only the optical properties are determined after the application of the disinfectant. In this case it can be concluded from the absolute value of the optical properties or from a comparison of this value with a reference value which can be stored, whether the disinfection was sufficient or not.
- This may be for the user e.g. be displayed optically and / or acoustically.
- optical properties encompasses any property of the light emanating from the skin area or area, such as the intensity or brightness, wavelength, color, etc.
- the present invention further relates to a blood treatment device, in particular a dialysis machine with a device according to one of claims 8 to 13.
- a blood treatment device in particular a dialysis machine with a device according to one of claims 8 to 13.
- This embodiment of a blood treatment device makes it easier for the operator to recognize whether the access point for the extracorporeal circulation is sufficiently disinfected (and therefore the puncture is performed can) or if this is not the case.
- the blood treatment device has a power supply for the emitter and / or for the detector and / or reservoir and preferably means for level measurement of the reservoir, wherein the reservoir or the reservoir containing the optically active substance and / or the disinfectant.
- the device or the blood treatment device comprises a reservoir for the optically active substance and / or a reservoir for the disinfectant.
- the blood treatment device preferably has means which indicate to the user whether the disinfection was sufficient or whether it must be disinfected again.
- the drawing shows a skin area 1 of a patient who is to undergo hemodialysis blood treatment or the area of the skin of a patient who has access to a blood treatment.
- an optically active substance S having fluorescent properties is applied to the skin region 10. It may, for example, be a solution containing a coumarin derivative having at least one fluorine atom.
- the optical properties of this coating are measured and stored.
- light having a specific, absorbing wavelength reference 20
- the fluorescent light emitted by this area of the skin is measured by means of a detector 30. This value is stored as a reference value.
- a disinfectant solution is sprayed onto this area of the skin and, after a certain exposure time, in accordance with the above conditions. again measured the optical property of the light emanating from the skin area.
- the disinfectant solution is designed to remove the optically active substance from the skin area.
- the device has a comparison unit that compares the remeasurement with the reference measurement. If the difference is sufficiently large, this is signaled to the user and the puncture can be made. If this is not the case, the user is signaled that a renewed disinfection must be made.
- the optically active substance produces areas which, when viewed by means of the detector 30, appear brighter than areas which are not or no longer exposed to the optically active substance, which facilitates the recognition of the removal of the optically active substance and thus the effectiveness of the disinfection improved.
- the detection can also be performed with the human eye, which presupposes that the optical activity or its change takes place in the region of the light perceptible by the human being.
