Definitions
- This invention relates to the area of equipment for medical use and means for cleaning same and in particular to an automated means for cleaning stethoscopes.
- stethoscopes used in medical practice are not disposable. They comprise components which include a head piece, having at least one diaphragm capable of transducing sounds, and ear tips for contacting the ears of a user which tips preferably provide an acoustic seal between the ear tip and the ear.
- ear tips While it is known for ear tips to be removable and cleaned, this practice is far from routine as the cleaning area may be remote, time consuming and be considered generally inconvenient. Additionally, health care providers use the diaphragm of a stethoscope in contact with successive patient's bodies thereby permitting the transfer of infection and contaminants between patients. While it is possible to use a cleansing agent such as an alcohol swab to wipe the diaphragm such cleaning procedures are often inadequate to completely destroy contaminants if indeed they are carried out.
- a cleansing agent such as an alcohol swab
- the invention is A chamber for sterilising stethoscopes automatically which chamber includes a base above which is located at least one sterilisation unit having at least one support device internal to it which device can accommodate at least one stethoscope and which chamber is provided with means for sterilising at least the head piece and the ear tips of a stethoscope.
- the sterilising means provided in the chamber include both ultraviolet cleaning means and means for physically cleaning a stethoscope, such as an alcohol spray, although any appropriate cleaning means could be used.
- the stethoscope support means in the chamber be able to support a multiplicity of stethoscopes. It is further preferred that the chamber be provided at its interior roof with ultra violet light sources which also act to heat the interior of the chamber and consequently the stethoscopes being cleaned.
- an alcohol spray source be provided from a container in the floor of the chamber which container is able to be filled and accessed from the exterior of the sterilisation chamber.
- the chamber have a conventional cabinet appearance with a front opening door providing easy access to the stethoscope support either for loading or unloading the stethoscope.
- the cabinet be able to be wall mounted or bench mounted however the precise mounting can be whatever is desired.
- Fig 1 Shows a view of the sterilising chamber cabinet as viewed from the front;
- Fig.2 Shows an interior view of the chamber cabinet with the stethoscope holder device displayed
- Fig. 3 Shows a side view of the chamber cabinet with an air vent in its side;
- Fig. 4 shows a schematic diagram of the stethoscope holder device in use
- a stethoscope sterilising chamber 10 containing a single sterilising unit 20 and a base 15 which contains the electrical apparatus used to operate the chamber and a timer mechanism.
- the base 15 also includes a container for alcohol 16, which container is shown withdrawn for filling in Figure 2, the alcohol being able to be sprayed over a stethoscope when in situ in the sterilising unit.
- the sterilising chamber of the invention 10 is shown mounted on a frame 40 but couid be bench or otherwise mounted as desired. It is also provided with a front opening door 11 with an inspection window 12 which provides a view of the stethoscopes in the unit.
- a stethoscope support means 21 is mounted and in Figure 4 a stethoscope 25 is shown positioned over the mount.
- an ultra violet light source 22 is mounted which is used to further disinfect the stethoscopes in addition to cleansing by the alcohol spray.
- Figure 4 shows only one stethoscope on the support means 21, in fact many stethoscopes can be placed on the support means at any one time.
- the particular shape of the support means is not germane to the invention and any device which could carry stethoscopes while exposing them to both the alcohol spray and the ultra violet source would suffice.
- the sterilising chamber could also utilise any sterilising means which achieves the desired effect of sterilising a multiplicity of stethoscopes within a relatively brief period.
- location of sterilising means within the chamber such as ultra violet light sources could be positioned anywhere within the unit, it is however desirable that the stethoscope eartips and head piece diaphragms be able to be both physically cleaned, such as with the alcohol spray, and disinfected by a means such as exposure to the ultra violet light.
- a sterilising chamber with a single unit and a single stethoscope mount is shown in the preferred embodiment of the invention shown here, the invention encompasses a unit with a plurality of stethoscope mounts.
- the sterilising chamber could also have a plurality of separate sterilising units which could be separately operated if desired.
