Nasogastric tube

The invention relates to a nasogastric tube ο

Nasal probes (drip contact) are known ₀ Usually a thin plastic probe with an outer diameter of 2 to 4 is inserted through the nasal cavity, the esophagus, into the stomach or into the intestine. They are used for resuscitation or resumption of nutrition for the sick; they are also used in the event of functional difficulties or organic obstacles to nutrition; feeding can be continuous or intermittent.

All known probes have the disadvantage that they are from the Protruding nostril. This gives rise to various inconveniences;

a) disability of the patient and unaesthetic appearance; These probes are attached by laying them around of the anterior end of the ear around the ear or by means of one or two bracing around the face Threads. Occasionally there will be a nostril at the nostril

1 O 9 O 2 7 / Π ^r > 1 5

Adhesive bandage attached while the probe end protrudes freely.

b) The outer end of the probe can be subjected to involuntary tensile or compressive loads during sleep or when moving causing dislocation and / or pain in the nasal or pharynx passages; this Disadvantage can be particularly uncomfortable for agitated patients in an unconscious state or for children.

The object of the invention is to provide a nasogastric tube that is barely noticeable and hardly influencing the appearance of the wearer to accomplish.

The object set is achieved by the use of a metallic or non-metallic body to be inserted into the nose, which is essentially frusto-conical and whose outer lateral contours are approximately adapted to the inner shape of the nose; it should partially lie against the nasal walls on the inside, but also leave a passage for unobstructed breathing. The introduced into the body tube, for example, is then fixed by usw- to impose a body provided on the pin (tube) or by inserting into a bore in the body of this body. The body and the hose can also be made in one piece ; this

this is particularly cheap and easy to do, when the nasogastric tube according to the invention is made of plastic.

The invention also includes an elastic hook, ribbon, wire or the like, which is matched to the outer shape of the nose and which serves as a holder for the nasogastric tube so that it cannot slip outward or inward. This wire should expediently first be guided on the outside of the nostril along the a groove and overlap the nasal bone. Its free end should be widened (or a pillow or something).

Like. Is attached), so that a soft, snug contact with the nose is guaranteed.

Another measure according to the invention can be seen in to attach a closure means to the body of the nasogastric tube so that the food cannot leak out. This can be done by a simple or (spring-loaded) plug or the like. But you can also Provide pressed lips against one another at the inner or outer end of the body and these during insertion, e.g. the food syringe or the like. Press apart. It is also possible to use the hose itself as a lip seal to train.

According to a further feature of the invention, the probe can also be made in several parts and the hose can be clamped to the body. For this purpose, it is expedient to use a 1 o 9 β ■; 7 / η R15

tubular body with an associated screw-on and / or clampable sleeve.

Preferably, a thickening should be on the tubular body, for example in the form of an olive, an Elypse, a cone or the like. Be provided; The hose is pulled over this and through an assigned gill agent (Socket) locked.

A preferred embodiment provides that a cylindrical hollow body with grids is assigned a sleeve with counter grids and that the hollow body is attached to the cylindrical part remote end then has the aforementioned olive shape.

It is also part of the invention to design the inlet opening into which the food is to be introduced so that one can they can connect positively to a pin (tip of the syringe, etc.), for example by conicity, wave shape etc.

Further advantageous and expedient features of the invention to be protected also emerge from the following Embodiments as described and / or shown; These individual features - like the features already mentioned - are also common (in combination) essential to the invention.

It can also be separated from the nasopharyngeal probe 1, with the latter being attached to the central channel in a detachable manner of the body 2 is drawn up and on this by a suitable means, for example a them from falling back in the interior of the nasal cavities obstructing posture (press fit, screwing, etc.)

To fit the nostril as perfectly as possible, the outer surface is rounded. The inner surface can be relatively flat. The front surface is preferred slightly convex. The lower surface carries the locking system.

The upper edge can have a rounded projection which corresponds to the nasal tip cavity when it is inserted.

The fastening system according to the invention is after a Characteristic of the invention is formed by an open ring forming the clip 3, for example in a left curve runs and is designed so that this organ is as close as possible to the lower, outer nostril part, the The alar groove and the lower part of the alar groove itself according to FIG. 1 follows.

This bracket 3 <(rounded support)> ends at its free one End in a shoe 4 to avoid uncomfortable penetration of the end into the meat.

This clip 3 can advantageously be made of plastic or made of stainless metal or even of plastic-coated metal, to some extent by nature To have elasticity that allows the exertion of a slight pressure in the sense of a locking on the outer Ala allows.

Depending on the type of material chosen for the production of the bracket 3, this can either be combined with the Main body to be cast or included in this according to FIG.

This clip 3 can also be attached in a hinged manner to the body 2 according to FIG. 3, and although movable about the axis 5 and loaded in its rotation by the spring with a suitable shape 6.

Since the essential characteristic of the hook (wire) 3 is its elasticity, which is necessary for holding the device: any suitable connection to the body 2 can be provided which achieves this result.

(Eg plastic) in one piece, the elasticity of the hook (wire) 'i du rc can η a reduction of its cross section from its Hasis to its tip can be achieved. In this case, this cross section can more advantageously adopt the approximate shape of the nostril groove in order to conceal itself there as well as possible. You can also cast plastic around a spring wire.

The particular asymmetrical shape of the main body makes the device necessary when it is introduced to give a direction. To facilitate this process is the application of a color indicator along a jacket line of the probe 1 is provided in order to enable marking (or: to give a clue). In order to prevent the liquids from flowing back to the outside, according to a further feature of the invention a closure element 7 is provided, the various modifications of which are shown in FIGS. 4, 5, 6, 7 and <J are.

It is provided that this closure takes place in various non-restrictive ways and means can, for example as a closure cap, pressure plug or with thread, concentric or diametrical plastic valves, ball valve, ball-cone lock etc.

The closure cap 7 can be designed as shown in FIG 1098 ^ 7 / DM 5

be that it oscillates about the axis 6 and by a spring 9, one point of which form the axis 8 at the same time can be held in the closed position.

But it can also be a simple stopper 7 a as shown in FIG its closure by pushing it in (similar to a push button) takes place in the channel 1 and which then preferably carries a tab 20 that holds it constantly and the Body 2 of the device is fixed or cast in one piece if for the manufacture of the main body 2 e.g. a soft plastic is used.

FIG. 5 shows a closure device by means of an outer plug 7b, which is held in a supporting manner by a spring 10 on the opening of the channel 1 and which can oscillate around the spring axis.

In this way, the cannula or nutrient solutions that connect the nasopharyngeal probe to the vessel can be easily inserted into the channel 1 .

One may also provide that the opening of the channel is caused by the introduction of these needle 1 itself. For this purpose the end of the channel 1 forms a soft plastic as shown in Figures 6 and 7 shown concentric valve whose free lips 21 or the channel 1 forming lips 22 at the introduction of the

According to Figure 8, the channel 1 can run into a valve in the form of a diametrical gap 11, the Opening caused by a simultaneous hand pressure at each end of this gap will.

The nasogastric tube according to FIG. 9 shows a multi-part embodiment.

This configuration makes it possible to choose a probe of any desired length, i.e. adjust the probe carrier after placing the probe on the exact, for reaching the desired organ required length is cut off without the risk that these two elements accidentally differ from each other loosen, since their interlocking with one another is final and secure.

For this reason, this device enables a much larger number of uses their greater adaptability to each case.

Accordingly, a body of the probe carrier 2 is formed according to a feature of the invention by the two parts 1.2 and 16 '.

The part 12 is a tube, one end of which has the shape of an elongated hollow olive 13 to make its light Introduction to probe 1 and to allow the natural tightness of the system.

In addition to the olive 13, this tube 12 comprises a cylindrical part 14 which has multiple projections Has circular teeth. These projections have the special training, preferably on average To have the shape of a right triangle, one side of the right angle at right angles to Axis of the device and its hypotenuse is directed to the opposite side of the olive. This Angle could also be greater than 90.

A sleeve portion 16 includes a hemispherical hollow portion at one end and a cylindrical portion which in its interior has the same circular projections arranged on the part 14 projections.

These two parts 12 and 16, or at least one of both are made of semi-elastic material such as polyethylene or any other material made so that these parts are sufficiently rigid, but at the same time allow the projections 15 and the complementary projections of the part 16 with thin

ORIGINAL INSPECTED

Cross-sections are sufficiently elastic to allow their deflection at the moment of insertion of the part 16, the general elasticity of the part also facilitates this introduction.

It can be seen that with so formed parts 12 and 16, the part 16 on the cylindrical portion of the Part 12 can slide and if sufficient pressure is applied to part 16 (while part 12 is held is), part 16 pushes itself over the (projections) Raser 15, whereby the hypotenuse of an inclined plane forming protrusions towards the insertion direction.

The elasticity of the various elements allows the projections to be compressed in time. It will be appreciated that these teeth (grid 15 and the counter grid prevents any rearward movement of the part 16 \ 15a, whereby it is locked on the part 12th

If the tube 1 has been drawn onto the olive 13 beforehand its end is between the bulbous end of the olive 13 and the hemispherical hollow portion of part 16 pinched.

The number of projections 15 is so small that it is always possible to find a position for the member 16, where it can compress the tube 1 in a constant and sufficient manner the tightness of the system and the same time U] fieine final Lock 1 0 9 H 2 7/0? J 1 5

to ensure. This part 16, which forms a unit with part 12, can carry bracket 3 (bracket), which is used to attach the device to the nostril.

It should be noted that to facilitate this function of the attachment to the nostril of the part 16 so it is provided that it preferably has an oval or semi-oval outer shape in section in order to adapt to the inner The outer wall of the nostril can be supported easily, as its volume provides a free passage for breathing and the Nasal secretions enabled.

Incidentally, according to a further feature of the invention, the outer end of the body 12 has a quick connect device which allows the tight inclusion of either a closure or any device, that are to be connected to the probe, for example a syringe, a funnel, tubes, etc. to the most diverse Uses.

For example, this quick connection is provided in the form of a conical socket part with spiral bulges 17. The element 18 to be connected obviously has the complementary training, that is to say in the present case In the case of a conical plug-in element with likewise spiral-shaped bulges 19.

This device with a screw thread in spiral conical bulges according to the invention has 1 0 9 8 2 7 / Π 5 1 5

the following advantages:

1. To enable a quick, practically taking place after a quarter turn clamping, because the spiral thread is very long and for this purpose can also have several concentric spirals.

2. The extremely easy cleaning of each of these parts, the spiral bulges reaching one another of the threaded base better than would be possible with any other screw thread, what a medical one Device is essential.

Finally, it should be noted that the arrangement of the elements 12 and 16 on the tube 1 easily with the help an arterial forceps, for example, can be made, one of its arms with a truncated cone split capsule can be provided, which facilitates the arrangement with a cylindrical split capsule Recording of the part 16 can be provided despite the bracket 3.

These two parts can thus easily be pressed firmly against one another, the tube 1 being held in place during this process by the pressure of the tweezers on the olive 13 .
