Description

The invention relates to a device for aspirating nasal secretion, which has an inner receiving space for receiving nasal secretion, the volume of which can be enlarged starting from an inserted position of the device, the nasal secretion being able to be sucked into the inner receiving space through a suction opening, the device for Formation of the inner receiving space has a front sleeve part which has a longitudinal axis, which has an inner space which is surrounded by a jacket wall in the radial direction and which extends towards a front end of the front sleeve part from a suction opening (5)

having end cap is limited.

A device of the type mentioned can be seen from FR 2632528 A3. The piston unit has a piston which is arranged in the cylinder space and to which a piston rod which protrudes from the rear of the cylinder unit is fastened. The spring, which urges the piston into the rear extended position, is arranged between the jacket wall delimiting the cylinder chamber and an outer wall surrounding the jacket wall, with the spring at its front end on an annular connecting wall connecting the jacket wall with the outer wall and at its rear end supported on arms connected to the piston rod and through slots in the

coat wall protrude. Before the piston after each

Suction process is brought back into the front insertion position, the device must be emptied. Further suction devices for sucking off body fluids can be found in WO 2018/127613 A1, CN 110201253 A, CN 206792708 U and DE 10 2015 219 775 A1.

The object of the invention is to provide an advantageous device of the type mentioned at the beginning, in which several suction processes can be carried out before the device has to be emptied. According to the invention, this is achieved by a device having the features of the claim

1.

The device according to the invention has a rear sleeve part in addition to the front sleeve part to form the inner cavity. This has an interior space which is surrounded by a casing wall and is closed towards the rear end of the rear sleeve part by a rear wall. This is firmly connected to the jacket wall. The jacket walls of the front and rear sleeve parts overlap in relation to the axial direction. The rear and front sleeve part can be pulled apart from the inserted position to increase the internal receiving space of the device into an extended position, with the overlap of the

Shell walls reduced relative to the axial direction.

In the device according to the invention, a relatively large volume of the inner receiving space remains even when the front and rear sleeve parts are completely pushed together, ie when the device is in the pushed-in position. After a suction process of nasal secretion, this can be in the extended position of the device in a simple manner by a shaking or centrifugal motion in the

be brought to the rear of the inner receiving space.

As a result, the front and rear sleeve parts can be pushed together again into the pushed-in position and the device is ready for a new suction process. In order to prevent nasal secretion from running out of the suction opening between the individual suction processes, the suction opening can be closed between the suction processes, for example by means of a plug-on closure cap. Thus, the device can be used over a longer period of a day until there is a suitable emptying option, as long as the inner receiving space of the device is not in the inserted position of the device

is completely filled.

In an advantageous embodiment of the invention, the front sleeve part is part of a front sleeve unit which has an outer wall which surrounds the skirt wall of the front sleeve part at a distance (at least over part of the length of the skirt wall). Furthermore, it is preferred that the rear sleeve part is part of a rear sleeve unit which has an outer wall which surrounds the jacket wall of the rear sleeve part at a distance (at least over part of the length of the jacket wall). For this purpose, the outer wall of the rear sleeve unit can protrude into the intermediate space between the outer wall and the jacket wall of the front sleeve unit, in which case the device can be designed as an overall closed unit. A reverse configuration is also conceivable and possible, with the outer wall of the front sleeve unit protruding into the space between the outer wall and the casing wall of the rear sleeve unit. In both cases, advantageously, a spring of the device in the space between the outer wall and the shell wall of the front sleeve unit and in the space between the outer wall and the shell wall of the rear

be arranged sleeve unit. This spring acts on the

front sleeve assembly and the rear sleeve assembly to the extended position. This spring is used in the

Device thus completely covered by the outer walls.

An advantageous embodiment of the invention provides that the device has a snap connection which, when the device is in the pushed-in position, holds the front and the rear sleeve unit in the pushed-in position. In this pushed-in position, the device can be transported in a space-saving manner. The snap connection can be

an actuating element can be opened.

It can thus be used in a simple manner by guiding the device, which is in the pushed-in position, to a nostril of the user and then opening the snap connection, with the sleeve parts being pushed apart by the spring into the extended position. In this extended position, further moving apart of the sleeve parts is limited by mutual stop elements. These stop members can be disengaged by the user, allowing the front and rear sleeve assemblies to be disassembled

and the device can be emptied and cleaned.

An embodiment of the invention is given below

described with reference to FIGS. 1 to 9.

The device for sucking out nasal secretion has a front sleeve part 1 having a longitudinal central axis 2 . This has an interior 3, which is delimited in the radial direction by a casing wall 1a of the front sleeve part. Towards the front end 4 of the front sleeve part 1, the interior space 3 is delimited by a dome-shaped end cap 1b. The end cap 1b has a suction opening 5 at the front end of the front sleeve part 1. In the exemplary embodiment, the suction opening 5 is aligned axially, as is preferred. The suction can as shown by a pin-like projection of

End cap 1b be surrounded.

In the exemplary embodiment, the casing wall 1a and the end cap 1b are formed from separate parts which are connected to one another with a material fit. Also a one-piece material

Training is conceivable and possible.

Apart from a front end section, the front sleeve part 1 is surrounded by an outer wall 6 . Thus, a backwards (= to the rear end of the front sleeve part 1

hin) open space 7 between that of the outer wall 6

surrounded portion of the front sleeve part 1 and the outer wall 6 is formed. This intermediate space 7 is closed at the front by an annular connecting wall 8 connecting the front sleeve part 1 to the outer wall 6, which in the exemplary embodiment is perpendicular to the longitudinal central axis 2

stands.

There is thus formed a front sleeve unit 9, which the front sleeve part 1, the outer wall 6 and the

Connecting wall 8 includes.

In the exemplary embodiment, the jacket wall 1a of the front sleeve part and the outer wall 6 are cylindrical. However, they are eccentric to each other, i.e. their longitudinal center axes are parallel but not on a common straight line. The intermediate space 7 is thus in a region of the circumferential extent of the front sleeve unit 9

larger than in a radially opposite area.

Although an eccentric arrangement has advantages (see description below), a concentric arrangement is also conceivable and possible. Also other than circular cross-section peripheral contours of the shell wall la

and/or the outer wall 6 are also possible.

The device also has a rear sleeve part 15 having a longitudinal center axis 16 . This has an interior 17 which is delimited in the radial direction by a casing wall 15a of the rear sleeve part. The interior space 17 is closed towards the rear end 18 of the rear sleeve part 15 by a rear wall 15b of the rear sleeve part. The rear wall 15b is at its radially outer edge directly to the jacket wall 15a of the rear

Sleeve part 15 firmly connected. It is therefore in the range of

radially outer edge of the rear wall 15b, a connection area between the rear wall 15b and the casing wall 15a. Here, in the exemplary embodiment, the rear wall 15b and the casing wall 15a are formed in one piece with one another. For example, the casing wall 15a and the rear wall 15b of the rear sleeve part 15 could also be formed from separate parts and be connected to one another with a material fit. A threaded connection between these two parts would also be conceivable and possible. For example, the jacket wall 15a could have an external thread at its rear end and the rear wall 15b could have a molded-on pipe socket with an internal thread in the region of its outer edge

can be screwed onto the external thread of the casing wall.

In any case, the rear wall 15b cannot be adjusted in relation to the casing wall. The volume of the interior 17 of the rear

Sleeve part 15 is thus unchangeable.

The longitudinal center axes 2 and 16 lie on a common one

straights.

The casing wall 15a of the rear sleeve part 15 is surrounded by an outer wall 19. Between the jacket wall 15a and the outer wall 19 there is a forward (= to the front end

of the rear part of the sleeve) open space 20.

At its rear end, spring arms 21 protrude radially inwards from the outer wall 19 . These spring arms are formed by an annular disk, which is connected to the outer wall 19 at the radially outer edge, for example is formed integrally with the latter, and in which radial slots emanating from the radially inner edge

are introduced. The jacket wall 15a is in the area of her

rear end formed with a cone-like thickening on the outside, in which a running in the circumferential direction groove-like depression is formed. When the outer wall 19 with the spring arms 21 is pushed onto this cone-like thickening of the casing wall 15a, the spring arms 21 snap into the groove-like recess and the rear sleeve part 15

is connected to the outer wall 19 in this way.

There is thus a rear sleeve unit 22 available, which the rear sleeve part 15 and the outer wall 19 with the

includes spring arms 21,

In the exemplary embodiment, the rear sleeve unit 22 also includes a cap-like cover part 32 which is fastened, for example snapped on, to the rear end of the rear sleeve part 15 . The rear sleeve part 15 has an annular, radially outwardly projecting projection at the rear end. In these are latching lugs of forwardly projecting latching arms 32a of the cover part 32

snapped.

The outer wall 19 could also be connected to the casing wall 15a in a different way, for example by a connecting wall which is made in one piece with the casing wall

15a and the outer wall 19 is formed.

In the exemplary embodiment, the casing wall 15a and the outer wall 19 are of cylindrical design. They are here but eccentric to each other, corresponding to the jacket wall 1a and the outer wall 6 of the front sleeve unit. Again, a concentric arrangement is conceivable and possible, as well as in

Cross section other than circular perimeter contours.

When the front and rear sleeve units 9, 22 are assembled, the jacket wall 15a of the rear sleeve part 15 protrudes into the interior space 3 surrounded by the jacket wall 1a of the front sleeve part 1, with the jacket wall 15a of the rear sleeve part 15 being sealed against the jacket wall 1a of the front sleeve part 1 is. A sealing ring attached to one of the two casing walls can be present for sealing purposes. In the exemplary embodiment, an elastomeric sealing ring is provided, which is arranged in an annular groove 26 which the outer wall 15a of the rear sleeve part 15 in

Area of the front end of the casing wall 15a surrounds.

The front and the rear sleeve part 1, 15 together thus form an inner receiving space 33, which for receiving

aspirated nasal secretion is used.

When the front and rear sleeve units 9, 22 are assembled, the outer wall 19 of the rear sleeve unit 22 protrudes into the gap 7 between the jacket wall 1a and the outer wall 6 of the front sleeve unit 9. Two axially extending Slots out, whereby a spring tongue 25 is formed. In the area of its free end, this has an outwardly protruding locking projection 25a. The outer surface of this

Latching projection 25a forms an actuating element 25b.

In the pushed-in position of the device, the latching projection 25a snaps into a front opening 10 in the outer wall 6 of the front sleeve unit 9 . In the extended position, the locking projection 25a is in a rear opening in the outer wall 6 of the front sleeve unit 9

snapped.

Due to the eccentricities of the outer walls 6, 19, the spaces 7, 20 are larger in the area of the circumference of the device in which the spring tongue 25 of the outer wall 19 of the rear sleeve unit 22 is formed. A larger free space for pressing in the spring tongue 25 is formed in this area. Because this free space is smaller in the other peripheral areas of the device, the capacity of the

inner recording space can be maximized.

The device also has a spring 30 which is designed in the form of a helical spring. This spring is arranged in the spaces 7, 20 between the casing wall 1a and the outer wall 6 of the front sleeve unit 9 and between the casing wall 15a and the outer wall 19 of the rear sleeve unit 22. With its front end it is supported on the connecting wall 8, with its rear end on the spring arms 21. The spring 30 is the device

acted upon in their extended position.

When the device is compressed from its extended position, the tension of the spring 30 increases until it reaches the pushed-in position, in which the locking projection 25a of the spring tongue 25 snaps into the front opening 10 of the outer wall 6 of the front sleeve unit 9 . The device is now for suction

nasal secretion ready.

For this purpose, the suction opening 5 is attached to the nostril and the latching projection 25a is pressed in by actuating the actuating element 25b so that it disengages from the front opening 10 . The spring 30 pushes the rear sleeve unit 22 out of the front sleeve unit 9

out, whereby the receiving space 33 increases until the

Latching projection 25a snaps into the rear opening 11 of the outer wall 6 of the front sleeve unit 9. The latching projection 25a and the rear opening 11 form stop elements which allow the front and rear sleeve units to be moved apart

9, 22 limit,

The negative pressure that forms in the receiving space sucks nasal secretion into the receiving space. This can be brought into a rear area of the receiving space by a tossing and/or shaking movement by the user. The device can thus be pressed together again until the insertion position is reached and is thus for one

new suction process ready.

For storage between individual suction processes, a cap 31 is placed on a section of the casing wall 1a of the front sleeve part 1 in front of the connecting wall 8 and closes the suction opening 5. The cap 31 can be held on the casing wall 1a by friction. Also an elastic one

Snap connection can be provided.

In order to empty and clean the device, the front sleeve unit 9 and the rear sleeve unit 22 can be taken apart. For this purpose, in the extended position, the latching projection 25a is pressed in by actuating the actuating element 25b. The stop elements formed by the locking projection and the rear opening 11 are thus disengaged and the front and rear sleeve units 9, 21 can be separated from one another, with the rear sleeve part 15 being pulled out of the front sleeve part 1. The device can now be emptied and

getting cleaned.

Temporary cleaning or pre-cleaning can be carried out by sucking water into the receiving space, preferably shaking the device slightly and draining the mixture by pushing the device together with the suction opening pointing downwards. This process is expediently repeated several times. If the device is subsequently disassembled for thorough cleaning, the

Recording room already largely clean.
