• this device effectively anchors a naso-gastric tube, it lacks stability and provides no means for maintaining a tube in substantially fixed alignment with a patient's naris.
• Michael M. Dillon provides an improved construction having an adhesive body to which is integrally formed a relatively rigid cylindrical clamp into which the naso-gastric tube is inserted.
• one aspect of this invention lies in providing a device for holding a naso- gastric tube in position relative to a patient's naris, while at the same time permitting a reasonable degree of freedom for the patient to move without significant discomfort.
• the naso- gastric tube holder of the present invention includes a planar flexible body with an adhesive lower surface for making an adhesive contact with a patient's nose and generally assuming the shape thereof.
• the present invention also includes a tube holding clamp in the form of a sleeve with a central bore therethrough and a lengthwise slit with interior ridges for spreading the tube holding clamp apart to permit lengthwise insertion, retention and removal of a naso-gastric tube from the bore and for closing upon the naso-gastric tube inserted therein for compressible and frictional retention of the tube.

• the naso-gastric tube may be inserted into either of the patient's nostrils.
• the connecting member permits adequate lateral and longitudinal movement of the tube in accordance with a patient's movements.

Therefore, the following advantages exist due to the cooperative nature of the structural components of the subject assembly and their positioning and cooperative placement on the patient in order to removably retain the naso-gastric tube in its intended and operative position.

• the preformed naso-gastric tube holder generally includes three primary elements, i.e. a thin, planar flexible body member 12 for adhesive contact with a patient's nose, a tube holding clamp 14 for frictionally and compressibly holding a naso-gastric tube 18 and a connecting member 16 for flexibly connecting the body member 12 and tube holding clamp 14.
• the body member 12 may be formed, for example, by injection molding of silicone material, medical grade rubber, or other plastic resin material, which may be of a porous nature to permit the skin to breathe. Medical grade silicone and rubber materials are well known in the art and are readily available through commercial medical supply channels.
• the bottom or confrontational surface 20 of the body member 12 may, most advantageously, include an adhesive coating material 22 over at least a portion thereof so as to permit adherence of the naso-gastric tube holder 10 to the nose in the position shown in Fig. 1.
• the material from which the body member is formed may be porous, although it is preferably provided with perforations 24 to allow the skin to which the body member 12 is adhered to effectively "breathe".
• the perforation further makes the body member more supple, causing it to conform more readily to the contour of the nose.
• skin irritation due to prolonged contact with adhesive material will be substantially reduced or elimnated, thereby ensuring greater comfort to the patient.
• a one piece integral construction of all components using less costly nonporous material may be achieved having the same advantages as a more expensive porous surgical material.
• the adhesive layer 22 may be any one of a number of biologically compatible, nonallergenic adhesives, examples of which include polymethacrylate, polyvinyl ethyl ether, poly- acrylate and acrylic ester copolymer. These adhesives have been used in the past and exhibit good adhesive properties, are substantially nonirritating to epidermal tissue and do not deteriorate when exposed to water and/or body fluids. For storage and handling the adhesive layer may be covered with a nonadhering plastic sheet 26.
• the tube holding clamp 14 comprises a tubular sleeve 28 having open ends and defining a hollow interior bor or bore 30, which, if desired, may be tapered from its outer end toward its inner end to more readily hold the tube 18.
• the sleeve is provided with a longitudinal slit 32, preferabl at its bottom (as applied to the nose) along its entire lengt
• the side walls of the slit are bevelled, as seen in Fig. 4, to provide ample means on the surface of the sleeve to allow the the user to insert his fingers and easily distend and spread apart the sleeve for reception, retention, or removal of the tube 18.
• the slit 32 has internally extending ridges 34 along the edges of the sidewalls of the slit.
• the tube holding clamp 14 has a thick wall 36 so as to be less flexible than the body member 12 and the connecting member 16. This lowered flexibility acts to stabilize the tube 18 where proximal to the patient's nose so as not to unduly flex and irritate the nasal passage. Since the clamp wall 36 is relatively thick, it has a resilient memory and is easily closeable about the tube 18, allowing the ridges 34 to securely hold the tube in place. The position of the ridges about the inner circular surface of the clamp wall 26 is not critical and may be placed where convenient.
• both the slit 32 and the bore 30 is somewhat less than the transverse dimension of the tube 18 so that the clamp 14 may compressibly grip the outer surface of the tube 18, without compression of the tube 18 and yet permit manual longitudinal repositioning of the tube 18 if necessary, while preventing inadvertent slippage or relative move ⁇ ment therebetween. Slippage is also reduced by the fric- tional interaction caused by the similarity of the plastic material with the material used for the tube itself. As will be seen from the following description of the connecting member 16, the tube holder can be easily lifted upon from the nose of a patient, although once it is in place, it will retain the tube in a substantially fixed and aligned position.
• the connecting member is molded into a shape retaining form, having a pair of perpendicular flat legs 38 and 40 respectively connected to the top surface of the body member 12 and the tube holding clamp 14 in such a manner as to position the clamp 14 below the plane of the body member 12 and in line with the naris chosen for intubation.
• the connecting member 16 is most advantageously formed integrally with the body member 12 and tube holding clamp 14, for example by injection molding, thus facilitating the construction of a superior device at a reduced cost which is simpler to utilize than prior art devices of the type having a multiplicity of components.
• the body member 12 is somewhat bell-shaped, although such shape is not critical.
• the body member has an overall transverse dimension slighly less than either the right or left surfaces of the nose
• the same device can be interchangeably used for the right or left nostril.
• the connecting member is disposed along the central line C-C of the body member 12.
• the connecting member 16 has a larger relative thickness than the body member 12.
• the connecting member 16 exhibits a shape retaining charac- teristic.
• an important aspect of the tube holder of the present invention is that the connecting member 16 is atached to the upper surface 20 of body member 12 in an overlapping fashion rather than merely extend from the edge of the body member 12. In this manner, the increased flexibility of the body member 12 does not serve to reduce the resiliency of the connecting member 16.
• the increased wall 42 resulting in extra thick ⁇ ness in the overlapping portion of the body 12 acts to reduce any hinge effect and relieves stress incident upon the body member.
• the holder of this invention allows the physician to insert the naso-gastric tube 18 through the patient's nose without first attaching the tube 18 to the holder, although the tube 18 may be secured to the patient initially if desired.
• the tube 18 is simply attached to the holder 10 by spreading the clamp 14 along its slit 32, inserting the tube 18, and allowing the clamp to grip the tube, after which the body member 12 is attached to the patient's nose if it is not already there.
• a holder in accordance with the invention may have a body member 12 approximately 1/16" thick and a clamp 14 having an approximately 1/2" outside diameter and an internal diameter of 1/8". The internal diameter may taper down to 3/16" at the inner portion of the bore. Overall, the holder of this inven ⁇ tion, has an overall length of about 3" from front to rear, ' along the center line.
• the present invention is useful in the treatment of hospital patients requiring naso-gastric intubation.
