Description
S-i~13 i~
Fl_ln _d_vlc_ f_r__asogastrlc_catheter and catheter ass_bly.
This invention relates to fixing device for a catheter for nasogastric intubation and an assembly of such a device, a catheter and a sheath.
Normally, a nasogastric catheter for supplying nutrition comprises a small diameter, soft plastics tube, having a weight sealed in the distal end thereof. The tube is inserted through the nose and the weighted end assists the tube into stomach or the intestine under the action of gravity. Food is supplied through the tube to one or two side holes positioned just proximally of the weight.
Nasogastric catheters may be kept in place for long periods of time and this is painful to the patient.
To relieve the pain, it is preferable that the catheter is formed of a material as soft as possible.
However, since a soft plastics tube lacks stiffness, it is difficult to pass the tube through the nostril, larynx and oesophagus, and then the convoluted stomach and intestinal passage.
For this reason, in conventional method, a guide wire is inserted into the bore of the catheter to increase stiffness during the catheter insertion process. However the guide wire or catheter must be lubricated to decrease the frictional resistance therebetween and in addition insertion of the guide wire is cumbersome. There is also a danger that the end of the guide wire may emerge through the side holes of the catheter and pierce the walls of internal organs.
It is undesirable to make the catheter of hard plastics for, notwithstanding patient pain, long term intubation can cause damage to body tissue in contact with the catheter.
It has been proposed to provide a relatively ~' stiff sheath or the catheter to aid insertion. One known sheath includes longitudinal split lines and is used in conjunction with a fixing device which retains the catheter in place whilst the sheath i5 withdrawn. The known fixing device is described in Japanese Patent Application No. 7gl78/1984, published November 6, 1985 under publication No. 60-222667, and comprises a body having a groove into which a catheter may be snapped, the wall of the groove thereby pinching the catheter firmly.
The sleeve is drawn through the fixing device and separated from the catheter.
This device has the disadvantage that if the catheter remains in the groove for a long period, for example between manufacture and use, it causes deformation which either reduces the pinching power of the groove or squeezes the wall of the catheter which reduces the cross-sectional area thereof.
Furthermore, the prior art fixing device allows undesirable rotation of the sheath and/or catheter as the sheath is removed.
The present invention aims to overcome the disadvantages described above. According to the invention there is provided a fixing device for a nasogastric catheter and comprising a base with an aperture therethrough, a bridge on the base having two holes in the span thereo~ and a slot through the base and the bridge connecting said aperture and holes to the exterior of the device, one of said holes being of larger diameter than the other.
The larger hole in the bridge span is sized to loosely locate a nasogastric catheter whilst the smaller hole is sized to grip the catheter against movement therethrough;
the slot permits the catheter to be squeezed into one or other of the holes. Preferably the inner hole is larger than the outer hole.
The invention also provides a nasogastric catheter ~J~Z~ S-' 74~3 ..~
assemb~y comprising -the fixing device afoxesald, a catheter and a catheter sheath splittable longitudinally into two substantially equal par-ts, the sheath passing through the aperture and the proximal end of said sheath being split to emerge through opposite portals of the bridge.
In this arrangement the sheath parts emerge through defined openings in the device and the troublesome rotation observed in the prior art device is obviated.
During manufacture of an assembly, the catheter is located in the larger hole of the bridge span. Accordingly the fixing device is unstressed during storage and the catheter is not squeezed. When it is desired to use the assembly the catheter may be snapped into the smaller hole for retention during insertion and withdrawal of the sheath; thereafter the catheter may be snapped back into the larger hole, or the fixing device removed for disposal.
The fixing device may be retained for use in a subsequent nasogastric catheter insertion procedure using a new catheter and sheath. The proximal end of the catheter is connected to a liquid food supply.
The inner wall of the sheath and outer wall of the catheter preferably have a matt finish which improves the sliding properties thereof; alternatively a lubricant can be used.
Other features of the invention will be apparent from the following description of a preferred embodiment shown by way of example only in the accompanyiny drawings in which:-Figure 1 shows a catheter for nasogastric intubation and incorporating a fixing device according to the present invention;
Figures 2 and 3 are enlarged explanatory views of the fixing device showing stages in the use thereof;
Figure 4 illustrates a stage in the insertion ~-7413 24~)~
process of a nasogastric catheter; and Figure 5 shows a prior art fixing device.
With reference to Figure 1 there is shown a catheter assembly comprising a catheter 11, sheath 12 and fixing device 13. The catheter 11 is of very soft plastic and is inserted in a plastic sheath 12 of a material having slightly greater elasticity and rigidity than the catheter. A weight 14 is encased in the distal end of the catheter and a side hole or holes (not shown) for supplying food are provided just proximally of the weight 14. An end fitting 15 for connection to a food supply is closed by a cap 16. The sheath tube 12 is weakened longitudinally either by a decreased wall thickness or by a line of generally incompatible material.
In the preferred embodiment the sheath is splittable into two halves and the free ends 17, 18 of the sheath ~, protrude through the flxing device as shown. ~ 3 - The fixing device 13 is shown in Figures ~ and ~
and comprises a base plate 21 having an upstanding bridge 22. Two holes 23, 24 are provided in the span of the bridge 22 and are connected by a slot 25 extending through the baseplate and one wall of the bridge. The outer hole 23 is larger than the inner hole 24. The baseplate has an aperture 26 therethrough.
Use of the fixing device is as follows. The catheter 11 is inserted into the stomach using the relatively stiff sheath 12. The catheter passes through the baseplate aperture 26 and the larger hole 23; the hole 23 is sized to allow free movement of the catheter.
The sheath 12 also passes through the base aperture 26 and the proximal end thereof is split, each part of the sheath emerging through a respective portal of the bridge 22.
When the catheter is inserted to the required depth, which may be confirmed by x-ray for example, the s-7~'3 catheter is snapped through the groove into the smaller hole 24 which is sized -to grip the catheter agains-t axial movement.
The sheath is then drawn through the fixing device for disposal; the catheter being securely held by the wall of the hole 2~. The two parts of the sheath are pulled in approximately opposite directions and the reaction force urges the fixing device against the patient's nose thereby retaining the catheter in place. The assembly thus allows a single person to instal a nasogastric catheter.
A partially withdrawn sheath is depicted in Figure 4 of the drawings. Once the sheath is withdrawn the catheter may bemovedback into the larger hole 23, where it is loosely retained, or the fixing device may be removed for disposal. The end fitting 15 is connected to a source of food or medication as required.
It may be advantageous to snap the catheter 11 into the smaller hole 24 during the insertion process.
Figure 5 shows a prior art device in which the catheter 31 is snapped into a hole 32 in a fixing device 33 for retention against movement therethrough. The free ends of a splittable sheath 34 emerge through an aperture 35 in the base of the device 33 but are not guided.
The sheath can of course be used to introduce an unweighted catheter into -the body because the sheath has the necessary rigidity and flexibility.
It is not entirely necessary that the sheath be splittable into two parts; a sheath with a single longitudinal weakened portion will also work.
The applicants do not intend the scope of the invention to be limited by the above descrip-tion of a preferred embodiment but only by the claims appended hereto.
