DE3734762A1 - Sound-suppressed disposable saliva suction nozzles - Google Patents

Abstract

Aspiration of saliva from the mouth of a patient by the dentist produces sounds which disturb both the patient and the medical staff. These sounds produced in the aspiration process can be eliminated, however, for example by the invention described below of a sound suppressor or by sound-suppressed suction nozzles. The nozzles used for aspiration of saliva comprise curved, usually transparent plastic tubes (often reinforced by wires). If a sound-absorbing, preferably fibrous, material were introduced into such a tube, a certain restriction of the saliva flow would result. On correct placement of this material, the noise could be reduced. <IMAGE>

Description

When aspirating saliva from the mouth of patients in Noises are generated by both dentist and patient also disturb the medical staff. These noises when sucking Process arise, but can be eliminated, for. B. by the invention of a silencer described below or by soundproofed suction nozzles.

The nozzles that are used in saliva extraction exist made of curved, mostly transparent plastic hoses (the often stiffened by wires). Would you be in a derar hose absorbing sound, preferably fibrous mate rial, a certain throttling of the saliva stream mes done. A reduction in noise could be more correct Placement of this material is done.

The invention is based on the fact that this material is preferred is fibrous, is correctly inserted into the suction nozzles largely combat the emergence of suction noise where with the suction power only within minimal, tolerable limits is throttled.

The sound-absorbing effect can even be found in the suction nozzles follow, but also in an essay on a conventional one Suction nozzle. Both are the content of this application for invention.

By compressing the sound-absorbing substance there may be more noise reduction, but also a very strong reduction in the flow of saliva. So far a regulation of the saliva suction, which occurs at up previous nozzles was not the case. By throttling the suction force can increase the sound absorption.

The invention is illustrated in the drawing Exemplary embodiments explained in more detail. It shows

Fig. 1 shows the application of the suction device (1) in the patient's mouth (schematically)

Fig. 2, the Speichelsaugdüse (1) with getrenn ter sound absorption (2) and throttling (3),

Fig. 3 shows a conventional saliva nozzle ( 1 ) with a silencer attachment ( 4 ) and regulated throttling and

Fig. 4 to 6 execution examples of silencer attachments ( 5 ), ( 6 ) and ( 7 ) with regulated throttling.

A conventional suction nozzle ( 1 ) in FIGS . 1 to 3 can be changed by the correctly dimensioned insert of sound-absorbing material ( 2 ) in FIG. 2 to a sound-damped saliva suction nozzle. By attaching a throttle device as a bracket ( 3 ) in Fig. 2, the saliva flow can be throttled and at the same time the sound absorption can be increased.

By plugging a silencer ( 4 ) in Fig. 3, the conventional nozzle ( 1 ) can be converted to a silenced and controlled saliva nozzle.

This is characterized by the insert of sound-deadening Ma is TERIAL of FIG. 3 and the graduated scale (16) on the SpeI cheldüse (1) in Fig. 3 or damper attachment to a muffler attachment (15) in Figures 3 to 6. The positioning of the sound on The nozzle can be created by frictional forces or by threads ( 17 ) on the nozzle ( 1 ) in Figure 3 and on the thread ( 18 ) on the silencer attachment in Figure 3.

The muffler insert in Fig. 3 must have sufficient length for adequate sound absorption, but also a sufficient cross-section to allow minimal throttling of the suction power if necessary. The water-permeable muffler insert ( 8 ), preferably fibrous material such as mineral fiber, can be given special shapes, such as. B. the form ( 9 ) in Figure 4 to fit on the upper side into the nozzle mouth and to receive a stiffener ( 12 ) on the lower side (e.g. rubber or plastic) so that the insert does not come out of the silencer can slip out.

Fig. 5 shows the sound absorbing insert ( 10 ) and a taper in the lower area in order to fit into the taper and to allow a hold with axial compression.

In Figure 6 the silencer insert ( 11 ) is given a shape that corresponds to the flat lower part of the silencer part.

The muffler may be perforated or slotted in unte ren part (14) in Figure 6 or tion in its tapered exten (13) in Fig. 5, so that the suction force not taken or the side (19) in Figure 4 by the various positions beeinträch becomes.

By the relative displacement or screwing of the sound damper attachment on the nozzle can the sound absorbing material that was inserted, compressed and throttling the saliva be regulated.

Claims (3)

1. Soundproofed saliva suction nozzles or a soundproofed one ter nozzle attachment to reduce noise when pulling of saliva with the ability to suck through Shape change of a packing in the nozzle mouth made of porous, water-permeable, sound-absorbing materials regulate materials, preferably fibrous material. 2. Device according to claim 1 with a separate silencer attachment for the suction nozzle. 3. Device according to 1 and 2 with throttling device for silenced saliva ejectors and their attachments.
