Abstract

A nasogastric tube introducer device comprising a curved, hollow tube 1 made of any appropriate material which has two extensions 2, 3 at its proximal end 4 and a hair-line slit 5 extending from the proximal end 4 to the distal end 6. The slit 5 is partially closed by a film of glue along half its depth (1, fig 2) so that the slit 5 is closed during insertion but remains visible. Preferably one of the extensions is spoon-shaped 3 to hold the device and the other extension 2 is shorter to protrude outside the mouth and prevent unwanted movement. The introducer may be made of any clinically compatible material. The introducer may be used in the nose or mouth of a patient and facilitates the insertion of a nasogastric tube into the stomach.

Description

A NbkTubelrr This inversion reds to a dev as to assist and wffl insertion

of a Ark tube (NGl) in the stomach An anased orcse pant The insertion of a Irk (sigh) tube is an important procedure that is perforrred in the daily practice at ark for ark and elective abdominal surgical cperabor. All verdlabed patents in the Arrive care unit have a nk tube placed for Reaped, diagnostic and or Ceding. The NOT is a narrow - bore set plastic / rubber tube. It is usually inserted \na the nose irbo the mouth and then it is advanced, blindly, so that its tip lies in the stomach. The aim is: 1) to ernFdy the stomach d secretion and prevent abdominal distension in irstinal obtrusion. 2) to instil drugs or feeding rrrbl irlD the stomach. 3) to erred the stench of air/ arc gases because a distended stomach may be damaged during blind insertion of equipments essential for bpb Keyhole) surgery e.g. emoval dthe gal budder.

However, in prac ice, the presence of a tracheal tube in the oral cavity makes the insertion of the pliable NGT (stomach tube) difficult because the laker tends to curl in the mouth instead of paging iron the stomach. To ormne this problem, the NGT can be cooled before USE tosllen it but the tube tends to warm up quickly end become set again once it is Produced in the mouth. Another method of inserting a NGT is to USE a Byrne to visualize the tip lathe NGT once it erlers the mouth from the nose and to employ a forceps to grasp its tip and advance it irk the stomach. This repealed grasping of the tube to advance it in the stomach leads to injury of the oral muoosa (lining) and severe sore throat abler the operation.

The usual practice, If the above techniques fail, is to grasp the tip of the NGT once it appears in the mouth cavity u ilh a forceps and draw it out of the mouth. Then select a tracheal tube with a diarrr layer than the NGT and split it abng its side. This modified tracheal tube is then pawed though the mouth ink the oesophagus. The tip NGT is threaded ink this tube and advanced inbD the stomach. The NGT is then sepal Born the tradeal the abng the slit and the tl tube is mmoved horn the oesophus.

Ash this technique is very successful, the use of a Todified tracheal tube for this purpose has several dish: (1) Trne is waked in pi and cuffing the tracheal tube to adjust its loath and to create a slit along its side. (2) The modified tracheal tube also has no means for grasp ng it outside the mouth and can easily be test irk the c.

(3) The rnanufadums of tracheal tubes may deny rmpority for any damage / ar caused by modification of their tracheal kites and their use for a dialect purpose than what they are intended for i.e. for ventilation and not as guide to the NGT.

This indicates that there is a need for a specifically designed, sterile, safe to use and readily available NOT-I because currency, there is noaxTrrllyavailable one.

According to the present indention a specific embodiment Of the deuce will nab be desabed by way of example with reference to the accornparng d sings in which.

Figure 1 is en wnabcdiagrarn aFthe NGTirducer.

figure 2 is a cross section aFthe NGT*,awing that halFaFthe depth aFthe slit is glued.

Figure 3 is a sd - T ale diagram to ill the technique at insertion at the NGT using the Producer.

As shown in figure 1 there is prwided a NGT inducerarrprsr a cut (1), 25 cm bng, 8 mrn infernal diameter plastic or rubber tube for adults (15 cm bng, 4 mm infernal diamerfor children). It has a hairline she slit (5) that extends Corn its tip (6) to the pxirnal end (4). The slit in the wall at the tube is inxnp (Fg. 2). HalFaF the depth at the slit in the wall at the inducer is glued (1) and the remaining half is left open as a partial slit This wit prevent the rgastic tube from leaving the inducer while allowing separation Of the Ark tube off the inducer by peeling open the glued part of the inducer. The NGT] also has two extensions (2 and 3) at the proximal end. One exlion of the tube is longer than the diner and has a spxrsh handle to assist holding the Producer during insertion lathe rk tube into the stomach. The other exlion is shorter end its purpose is to prevent the NGT] born being test into the oesophagus during insertion of the rasbk tube. The inducer tube can be made Many He rrrial e.g. set plastic, polyvinyl chloride or even rubber. Vanous sizes of tubes can also be designed for use in children and adults.

Claims

clue - 1. A nag kite producer deuce for assisting medical personnel in the

sate and easy insertion of a nasogsike in the stomach of an arffd parent is apprised at a curved hdbw tube made any apt rrrial e.g. nabber, has two ex ensigns at its paternal end and a hair- line slit extending tom its proximal end to be distal end so that the slit in the wall d the tube is partially closed by append At a fly gee along half of depth Lithe sit and the remaining outer half bathe set is let open lo help mark the position of the slit during the process At peeling the rbk tube off the inducer. This design the slit p events the nasogasbtube tip tom leaving the Producer tube during insertion but aliens the Producer tube to be easily separa ed Morn the r Abe.
A device as claimed in cairn 1 u herein the cured tube has two emulsions at its paternal end. One extension is spxr and is destined to facilitate holding the Producer tube and help Oh easy irern of the nasok tube and the second extension is shorter but preludes beyond the math opening and is aimed at preventing the inducer tube born it dgen into the mouth cavity and or ils disappearance inbo the oesophagus during insertion.
3. A device as described herein with reference to figure 1, 2 and 3 of the accompanying drawings.

3. Adevice as claimed in clam 1 and claim 2 wherein the device coup be bused Morn any notarial aewith its use in clinical practice.

4 A device for the insertion of a Irk tube in the stomach of an ah orcornabse palentdirey vie the nose end or vie the mouth byrnedical personnel and as described herein with reference tonsure 1, 2 end 3af the Accra - nyingdraMngs. / -

Amendments to the claims have been filed as follows Claims 1. A nasogastric tube introducer device for assisting the insertion of a nasogastric tube into the stomach of an anesthetized or comatose patient is comprised of a curved hollow tube with two extensions at its proximal end and a hair-line slit extending from its proximal end to its distal end such that the slit in the wall of the tube is partially closed by a film of adhesive or glue along half of the inner depth of the slit and the remaining outer half of the slit is left open to help mark the position of the slit.
