Description

ARRANGEMENT AT AN EAR SUCTION DEVICE FOR SUCTION OF

UNWANTED PARTICLES IN AN AUDITORY CANAL

Technical field

[0001] The present invention relates generally to an arrangement at an ear suction device for suction of unwanted particles in an auditory canal. The ear suction device presents a gripping part for holding on to during suction. The gripping part presents recesses in which a front part of an elongated suction pipe by its tip is able to be inserted before the suction. The recess presents enclosing walls which encloses the tip, in order to create an anvil during bending of the front part into a bend, which then is able to reach and suck up the unwanted particles near/by an eardrum in a bent auditory canal and to remove these through a, one at the gripping part arranged, suction pipe.

Background art

[0002] In constructions of the present kind available at the marked today, different recesses are used to create an anvil during bending of the front part. This is today done by the assistance of a free laying bending instrument, which has to be in a vicinity of the personnel which is about to suck clean an auditory canal from unwanted particles such as wax, bacteria, skin cells, blood, dirt, etc. The auditory canal is bent and the front part of the elongated suction pipe is straight and has to be adapted to the auditory canal just about to be cleaned. Each auditory canal has its own special appearance and can be more or less bent. The personnel shall suck all the way to an eardrum, whereby the size of the bend and its location must be adapted to a desired shape before suction. Here is when problems often occur. Often you do not find the bending instrument. If you find one it can be an earlier used one and thereby can be exposed to bacteria. The bending instrument is unwieldy to use and to clean. You often have to change working position to grip and to lay aside the instrument. The bending instrument is not sterile, but is placed loose in the open air with a risk of being contaminated with dirt. Therefore it needs occasional sterilization, which is a large problem.

RECORD COPY - TRANSLATION

(Rule 12.4) Furthermore, the bending instrument is not always on the right place and needs to be sought-after. This takes time and interrupts the caring for the patient.

Summary of invention

[0003] An object of the present invention is to solve the problems with the above mentioned constructions by creating a cheap, simple, reliable and easy to handle ear suction device, whose gripping part and elongated suction pipe are wrapped in a sterile way. The gripping part presents recesses for the bending which then are sterile. The thoroughly washed hands of the personnel are free from bacteria, whereby the bending of the front part can be done without putting aside the gripping part, because the loose front part is held in one hand and the gripping part in the other hand, in order to create the bending.

[0004] With the invention it is created a cheap and simple technical solution which is easy to work with and which keeps the bacteria away. The invention is an arrangement at an ear suction device for suction of unwanted particles such as for example wax, bacteria, skin cells, blood, dirt, in an auditory canal and at different parts of a middle ear and transmit this to a collection part where a suction pump is creating the suction effect. According to the invention the ear suction device presents a gripping part made of plastic or metal, adapted to be held by one hand during suction and which comprises a rear connection part, where a suction tube made of transparent plastic, to ensure visualization of the sucked in unwanted particles, is connected. The gripping part presents a front connection part, where an elongated suction pipe made of metal is connectable. The gripping part presents recesses in which the front part of the elongated suction pipe, by its tip can be bent, by inserting the tip and possibly also a part of front part in the recess, which is 2-20 cm long, after it has been released from the front connection part before the tip is about to suck in the auditory channel. The recess presents enclosing walls, which at least partially encloses the tip by the insertion, to create an anvil which holds it during bending of the front part. This is done by using one hand to hold the gripping part and the other hand to hold the elongated suction pipe to establish a desired appearance of the bend, which before suction is bent after the appearance of the auditory channel and is thereafter put in place by the front connection, whereby suction can be started in order to suck in the unwanted particles for example in vicinity/by an ear drum and transmit the unwanted particles through the gripping part and the suction tube. The different parts of the ear suction device are packed sterile and are only used once, then they are thrown away. Since the personnel must have washed their hands free from bacteria or must wear sterile gloves during suction of the auditory channel, the hands are usually completely free from bacteria, whereby the recesses not so easily are contaminated by bacteria. In one embodiment of the invention a rear part of the suction pipe, which is connected to the front connection part, presents a cover element, which stretches across the longitudinal direction and covers the recesses during suction, in order to protect these from possible bacteria from the hands, whereby fingers instead end up on the cover element, which can cover the entire or parts of the gripping part, whereby during continued bending in earlier covered recesses, the tip is protected from bacteria attack. In order to, in a more easy way, be able to find the correct recess, which fits the diameter and length of the elongated element, the gripping part is marked with information such as numbers and letters on the exposure surface by its corresponding recess.

[0006]As can be seen in figure 1 and 2, it is disclosed an ear suction device 1 for suction of unwanted particles 3 in an auditory channel 2. The ear suction device 1 presents a gripping part 4, for holding during suction and a rear connection part 5, where a suction tube 6 is attached and a front connection part 7, where an elongated suction pipe 8 is attached. The gripping part 4 presents recesses 10 in which the front part 9 of the elongated suction pipe 8 by its tip 20 shall be inserted. The recesses 10 presents walls 1 1 , which encloses the tip 20, and create an anvil 12 during bending of the front part 9, in order to create at least one bend 13. The recesses 10 are arranged in the enclosing exposing surface 14 of the gripping part 4 and are shaped as round holes 21 , which are 1-20 mm deep and who's enclosing walls 11 attaches around the tip 20, when the bend 13 is accomplished. The gripping part 4 is an elongated body, through which, in its length direction 15, a channel 16 runs, through which the absorbed unwanted particles 3 are transported from the elongated suction pipe 8 to the suction tube 6 to be collected. The gripping part 4 has a maximum length of 8 cm, its thickness is 1 cm max and its width is 3 cm max. The rear attachments part 5 presents a first protuberance 17, stretching in the length direction 5. The end 18 of the suction tube 6 is thread over or into the first protuberance 17 and is held there, with the channel 16 running through the end 18.

[0007]As is shown in figure 3 and 4, an embodiment of the invention is disclosed, where the enclosing walls are made of a hard and stiff material 26 of hard plastic, such as for example polycarbonate and/or a metal, who^'s hardness can withstand the pressure from the tip 20 without deforming, during bending of the front part 9 in order to avoid that the enclosing walls are deforming and so that the remaining part of the gripping part 4 can be made of a more handle friendly plastic material which feels comfortable to hold on to and which becomes lighter. The gripping part 4 presents an aeration hole 25, which attaches to the channel 16, whereby a suction effect is accomplished in the elongated tip 20 of the suction pipe 8 when the aeration hole 25 more or less is covered by a finger. The suction effect becomes in this way adjustable from a minimum to a maximum after the desires of the personnel which are sucking up the unwanted particles 3.

[0008]As shown in figure 2 and 4, it is disclosed that the front attachment part 7 presents a front wall surface 23, which spreads in a direction cross the length direction 15. The front wall surface 23 presents two holes 21 with different diameters, whereby one is 1-2 mm and the other 2-3 mm, having a depth of approximately 3-5 mm. The holes 21 are somewhat protected from the touch of fingers, which not so easily touches the front wall surface 23 and adds bacteria during suction, which makes this a preferable place for the holes 21. The diameter of the holes fits the most frequently used tips 20. The front wall surface 23 presents the second protuberance 19, which stretches in the length direction 15 pointing away from the front wall surface. The channel 16 runs through the front wall area 23, where the elongated suction pipe 8 is attached in its rear part 22, which encloses the second protuberance 19 in order to hold on to the elongated suction pipe 8 in the rear end 22, which presents a cover element 24, which stretches across the length direction 15 and covers the two holes 21 during suction, in order to further protect these from bacteria, whereby else bacteria is transferred to the tip 2 during an additional bending of the tip 20.
