Definitions

  • This invention relates to the field of masks, and more specifically those masks which are used to administer a gas, such as oxygen, to a patient, particularly when a naso-gastric intubation procedure is to be accomplish simultaneously.
  • a gas such as oxygen
  • the basic mask which is available today uses neither a valve nor a reservoir bag. Exhaled air from the lungs of the patient is usually vented through holes in the body of the mask. In view of its convenience and relative comfort, the basic mask is widely used whenever moderate oxygen concentrations are desired for short periods of time. This might occur, for example, during the postoperative recovery state of a patient. Such a mask might also be used, for example, during either tem- porary or interim therapy when a patient is being weaned from continuous oxygen administration. Most masks available today are relatively crude, causing a prediction of the exact volume of oxy- gen delivered to the patient to be impossible. However, it is known that the delivered concentrations vary from 35% to 55%, at ga-s flow rates of 6 to 10 liters per minute.
  • the nasal cannula is an appliance which nor- mally includes two tips which extend from an oxygen supply tube and are inserted into the nostrils of a patient.
  • the cannula can be held in place by head straps or by bows that hook over the ears, in the manner of eye glasses.
  • the cannula suffers from the disadvantag-e of being instable, i.e., it is easily - dislodged from a restless or unobservant patient. While a doctor or nurse making medical rounds might note that an oxygen flow meter is open, he or she might not notice that the cannula is so twisted out of place that the patient could not get any significant amount of oxygen.
  • the cannula also suffers from the disadvantage that it is often necessary to pay attention to a patient's comfort when instituting oxygen treatment.
  • An excessive flow rate of oxygen the definition of which varies according to the patient, can produce a considerable amount of pain in the frontal sinuses of the patient.
  • nasal pathology as a deviated -septum, mucosal edema, mucus drainage, and polyps may interfere with a patient's oxygen intake.
  • a naso-gastric tube might be used together with the nasal cannula, the uti- lity of the latter is further degraded.
  • the mask is impossible to conform the mask to the facial con- figuration of the patient and, in many cases, the mask is generally askew.
  • Such incorrect seating of the mask allows oxygen to freely pass to the atmosphere, resulting in treatment of the patient with a decreased and uncontrolled volume.
  • the stability of the mask as well as the patient's comfort are complicated by the tube.
  • the mask is. * much less secure and more easily dislodged by an unobservant, restless, or mobile patient.
  • the tube is usually placed across and secured to the facial skin in an attempt to prevent relative movement among the patient, tube, and mask. The taping of the tube to the skin often produces discomfort and runs the risk of producing a pressure necrosis of the skin.
  • That disclosure includes a rigid body which may extend down the throat of the patient; it does not relate to a structure which would facilitate a naso-gastric intubation. Consequently, a need currently exists for a oxygen-administration device which may be simultaneously employed with a naso-gastric tube in such a manner that the volume of oxygen can be controlled at least to the same extent as may be attained with a fully seated oxy- gen mask.
  • the present invention relates to an oxygen mask which may be employed in the well-known manner.
  • a mask is produced, for example, by Ideal Medical Products of Lansing Michigan.
  • a mask which can be utilized with the present invention may be of any desired size, configuration, etc.
  • the mask is relatively pliable, such as might be the case with a soft, clear vinyl, and easily adaptable to the facial contours of the patient in order to provide sealing throughout the periphery of the mask body where it con- tacts the skin of the patient.
  • the present invention rela- tes to such a mask which is adapted to particularly pro- vide for the passage of a tube therethrough, such as that which might be employed in a naso-gastric intuba- tion procedure.
  • the present invention which may be employed in a wide variety of embodiments, basically comprises a fenestration in the wall of the mask body. When a tube is not in place in the fenestration, the latter will be substantially closed so as to minimize ⁇ r completely prohibit any escape therethrough of oxygen from the interior of the mask body.
  • the fenestration may be provided adjacent to and extending through the sealing portion of the mask.
  • the fenestra- tion may be located at any desired position about the periphery of the mask so that a tube may be so arranged as to be substantially and comfortably aligned with the nostril of the patient.
  • the fenestration may be of any desired size and configuration. In many cases, however, it will be preferred that the fenestration be of such a con- figuration that it will firmly hold the naso-gastric tube in place without allowing relative movement between the tube and the mask. In some embodiments, it is currently preferred that the fenestration be provided with some type of lining material or other structure which will provide a form of seal, either about the tube, or across the fenestration itself so that the

  • a mask 11 including a body 13 which surrounds an internal cavity.
  • the body 13 may be placed over the nose and mouth of a patient so that the patient may inhale and exhale into the mask cavity.
  • the periphery of the body 13, at the open edge of the cavity, is pre- ferably surrounded by a sealing surface 15 which may be placed against the patient's face to prevent the passage of gas or oxygen in or out of the mask cavity except through preselected passages.
  • the mask body 13 and sealing lip 15 are pre- ferably constructed of transparent, thin, pliable plastic which is relatively inexpensive. Consequently, the mask readily conforms to any patient's face.
  • the upper portion of the mask may ' be provided with a pliable nose piece 17 which may be bent to generally conform to the nose of the patient. The nose piece assists in holding the mask in place and keeping it sealed against the patient's face.
  • the mask may be provided with a band, strap or earpiece 19 which cooperates with the head of the patient in order to hold the mask to his face.
  • a relatively rigid inlet connection device 21 may be fixedly attached to the mask body 13 for receipt and support an oxygen or other gas hose 23.
  • OM can be fed through the hose 23 into the mask 13 through the connector 21 for increasing and controlling the oxy- gen intake of the patient.
  • one or more aperatures 25 may be provided in either or both sides of the mask.
  • the mask may be provided with a cleft or fenestration 31, through which a naso-gastric tube 33 may pass and within which it may be secured.
  • two clefts or fenestrations may be provided for the passage of a like number of naso-gastric tubes.
  • the cleft or fenestration 31 be so posi- tioned as to allow comfortable and convenient aligned of a tube 33 with the nostril -of a patient so that the use of the mask and the naso-gastric tube will not conflict with one another in servicing the patient.
  • the fenestration 31 is shown shaped in a form similar to a "key hole" 35 having a foam rubber or other flexible lining 37 which may be split down the middle for inser- tion and receipt of the tube 33.
  • the lining and the central slit or opening therein preferably extend down to and through the sealing portion 15 of mask 11. Consequently, proper selection of the liner 37 will allow the slit to remain substantially closed throughout the entire length of the fenestration 31 when a tube, such as that illustrated at 33, is not in place.
  • the lining 37 will closely surround the tube and be substantially closed throughout its length for the remainder thereof. As a result, such a fenestration will produce
  • OMPI a significant advancement in the technology of thera-Guinic application of oxygen simultaneously with the use of a naso-gastric tube.
  • the volume of oxygen applied will be relatively precise in accordance with the orders of the doctor to the medical personnel.
  • the naso-gastric tube would be applied to a patient in the well-known manner.
  • the mask may then be placed in position against the face of the patient.
  • the cleft or fenestration 31 may be manually split and pushed over the tube 33 until the tube is located in the upper portion of the slit or opening.
  • the tube may be substantially sealed and firmly seated in the upper portion of the key hole-shaped opening and the mask will remain sealed against the face of the patient.
  • the fenestration 41 may comprise a slit formed in the bottom portion of the mask and extending upwardly from the sealing 15 to a location intermediate the seal and the connector 21.
  • a rib 45 may be formed integral with or suitably attached to the body 13 about the vicinity of the slit, thus preventing stress, imposed when the tube is installed, is in place, and/or is removed, from damaging the mask.
  • the edges of the slit i.e., the adjacent portions of the mask body 13, will form a pair of flaps 47 and 49 which are normally closely adjacent one another to seal off the fenestration.
  • the fenestration may again be manually split and pushed over the tube.
  • the tube reaches the upper portion of the split, it will thus be seated and substantially sealed therein.
  • the fenestration may then be closed so that the flaps 47 and 49 are as close together as possible.
  • the naso-gastric tube can be properly positioned and will not move about if the patient should be become restless or mobile.
  • the mask will continue to be sealed against the patient's face at all times to provide the optimum sealing effect. Any oxygen loss through the fenestra- tion slit between flaps 47 and 49 will be minimal since any separation therein will be relatively small.
  • FIGS. 6-15 it can be seen that a wide variety of shapes, sizes, etc., of clefts or fenestrations may be employed, realizing that they may be used singly or in pairs and at any convenient location in the mask so as to properly hold the naso-gastric tube in a convenient and comfortable location for the patient.
  • the mask body 13 may be provided with a fenestration 61 having a slit 63 therein and a reinforcing wall or rib 65 spaced from the rib a convenient distance for allowing the insertion and position maintenance of a tube (not shown) .
  • the fenestration 61 may be formed in a shape resembling a crook of a sheppard's staff. Consequently, when the mask is installed over the tube, the latter may be moved into the inner end of the slit to provide substantial sealing of the tube and also to firmly ensure that it is properly seated and held in place. If desired, of course, the internal end portion of the fenestration 61 may be enlarged so as to provide an opening of substantially the same size as that for the cleft 31 shown in Figure 1.
  • the slit 63 may be formed in the wall of the body 13 similarly as shown in Figure 5, or it may be provided between opposed edges of a foam rubber liner, similar to that structure shown in Figure 1. In either case, the slit will be
  • a fenestration 71 is illustrated having a slit 73 for receipt of a naso-gastric tube.
  • the vicinity of the slit 73 may be substantially surrounded and strengthened by a rib or wall 75 of substantially circular configuration.

  • flaps 77 and 79 may be part of the wall of mask body 13 or they may be separate, attached elements. If desired, this fenestration may be held in the closed position during use, such as by means of a suitable clasp 74 which may include one or more protrusions 76 and a cross-piece 78. Alternatively, the protrusions may be used to located and hold a small rubber band or similar element to hold the fenestration closed.

Abstract

Masque (11) servant a l'administration d'un gaz, tel que de l'oxygene, a un patient et pouvant etre utilise dans une procedure de tubage naso-gastrique sans interruption du joint entre le masque et le visage du patient. Le corps (13) du masque comprend une fenetre, ou ouverture (31) au travers de laquelle le tuyau naso-gastrique peut etre insere. La fenetre est faconnee de preference pour retenir le tuyau (33) dans une position qui est commode pour le patient et qui elimine ou reduit au minimum la quantite de gaz degagee dans l'atmosphere a l'exterieur du masque. Dans au moins quelques modes de realisation, l'ouverture est fermee lorsqu'un tuyau n'est pas insere au travers de celle-ci de sorte que le masque puisse etre utilise normalement sans aucune perte de gaz par l'ouverture.
