ApplicationMarchl, 1949,?Serial'No. 79,073
rhage is to pack the nasal passages with fibrous material such ascotton or sterile gauze. Dressings of this type are objectionable for three reasons, first, they must be changed every twentyfour hours or they tend to become rancid; :sec-
ond, they increase the liability of involvement of the middle-ear by reason of infection via the Eustachian tubes; and third, the removal of the old dressings and insertion of a fresh dressing frequentlybreaks the cloth and the hemorrhage Accordingly, one of the objects of the present invention is to provide an instrument in the form of a flexible rubber tube which may be inserted .in the nasal passage, after proper preparation-of the nasal membranes, and having spaced inflatable bags which, when the instrument is once in .place, may be readily inflated to block off the post-nasal as well as the intra-nasal portions of the nasal passage to form, in eifect, a dam in the zone of the bleeding to assist in the formation of a clot and, at the same time, prevent bleeding from the nose and mouth.
A further object of the invention is to provide a surgical instrument of the type set forth which is easy to manipulate in its initial deflated form, and which utilizes no metal valves for closing the inlet to the air passages once the bags are inflated, thereby avoiding discomfort'to the patient when the instrument is in place in the respect that the portions extending from the nose are not heavy and therefore do not impose weight when resting on the patients lips or face. In that connection, it .is proposed to provide theair passage inlets leading to the inflatable bags'with self-sealing rubber stoppers which may be pierced by an ordinary hypodermic needle connected to a bulb-type air pump, both elements being usually a part of doctors equipment. On removal of the needle the bags will remain inflated for an indefinite period of time. When it is desired to deflate the bags, it is only necessary to insert a hypodermic needle in each of the stoppers or plugs, the needle being detached from the pump tube, thereby to let the air in the bags escape.
Another object of the invention is-to provide instrument which may be made of surgical rubber throughout and which .is adapted to rubber molding techniques thereby to provide economical production.
set forth in the following description and claims, and illustrated in the accompanying drawings, in which:
Figure 1 is a diagrammatic view illustrating the-application of the invention;
Figure 2 is a perspective view of the instrument in its deflated form prior to insertion in the nasal passage;
Figure 3 is an enlarged detail sectional view illustrating the body of the instrument with :air passages formed therein leading to the inflatable bag elements;
Figure 4 is a detail view illustrating the manner of the insertion of a hollow needle in one of the self-sealing plugs to effect inflation of a selected bag element;
.Figure 5 is a detail cross section of a self- .sealing plug after the needle has been withdrawn.
Similar reference characters designate corresponding parts throughout the several figures of the drawing.
Referring to the drawing, it will be observed that the instrument indicated generally as A includes a tubular body portion l preferably formed at its leading end 2 with an eye 3 for receiving a cord or string 4, and atits opposite end with a (forked terminal portion F. The interior of the body and the arms of the forked portion-are .provided with ducts or passages as will presently appear.
For example, the medial portion of the body is provided with a longitudinal air passage or duct 5 .having a port 6 at its forward end for communicating with a rubber bag element 1 defined by securing spaced portions of a thin rubber sheath to the outside of the body I by flexible means such as thread or the like, as indicated at '8. The inlet end of the passage 5 communicates with the branch ll] of the forked terminal portion through the passage 5a.
The body I is also provided with a relatively short'longitudinally disposed air passage or duct 'H having a port [2 communicating with a bag element l3 which is secured at spaced points to the outer surface of the body 0 as indicated at 14 by thread or its equivalent. The passage ll communicates with the branch E5 of the forked terminalportion through a passage Ha. As will be-seen'from Figures 1 and 2, the inlet ends of the branches l0 and I5 of the forked tail or terminal portion F are provided with valves in the "form "Of'StODDBI'S or plugs S made of self-sealing pieces or sections of tubular rubber secured to the outer side of the body I by a flexible tie or by vulcanizing the ends of the bags to the body, nevertheless, it is preferred to use a suitable length of surgical rubber in the form of a onepiece tubular sheath and slip it over the body I, or roll it on, and then secure it as indicated at 8-8 and I4--l4 to define the bags. Using a tubular sheath in this manner enables ready replacement by the physician if one of the bags burst. That is to say, spare sheaths may be furnished for use with the body I so that a physician or his attendant may readily cut the threads 8 and I4 of a damaged sheath, remove it, and put on a new one and again replace the threads at proper points to define the limits of the inflatable bags.
Assuming that the device is in its deflated condition as shown in Figure 2, it will be understood that the same may be inserted in the nose of the patient with the leading end having a string 4 attached, if desired, as in cases of narrow or tortuous nasal passages. The use of the string or cord is optional depending on the type of passages in the patients nose. The string may be inserted in the nasal passage by an appropriate instrument until it can be picked up at the back of the throat, through the mouth, by the same Or another instrument thereby to assist in placing the device in position under the conditions stated. When installed, the forked terminal portion F lies outside of the nose with the rubber plugs S exposed. The physician may then select the bag elements I and I3 to be inflated. This is accomplished by piercing the plug S in the branch H], for example, leading to the air passage with a hypodermic needle connected with a tube T by its usual coupling C, said tube in turn communicating with a rubber bulb type hand pump P. Preferably, though not necessarily, a 20 gauge needle is desirable since it is easier to insert in and pull out, and also less apt to break or bend, while, at the same time, permitting quicker inflation and deflation. The pump P preferably is an air pump but a liquid pump may be used since any desired fluid medium may be used to inflate the bags. Upon manipulation of the pump P, the post-nasal bag I may be inflated to the desired extent by the physician who is usually skilled in knowing how much fluid is to be placed in the bag. After the postnasal bag I has been inflated, the physician will ,grip the branch ID of the fork F to temporarily seal the passage 5a while th needle N is removed from the plug S and the fluid will then be automatically trapped in the bag I, and its communicating passage 5 and 5a, by the self-sealing plug S.
The intra-nasal bag [3 may be inflated, and left inflated, by the physician following the same procedure just described in connection with the bag I, so that when both bags are inflated as shown in Figure 1, they will block off the area of the hemorrhage.
The branches Ill and may be made of contrasting color to indicate which bag the branch leads to or they may be otherwise identified.
When the instrument is to be removed from the patients nose, deflation of the bag is accomplished by successively puncturing each self-sealing plug S with a hollow needle of the hypodermic type which is detached from the pump, thereby to let out the inflating fluid.
From the foregoing, it is believed that it will now be apparent that the present invention provides a simple and practical form of instrument for controlling intractable nasal hemorrhages which may be readily manipulated by the physician and cause the patient a minimum amount of discomfort.
1. A tampon for the control of intractable nasal hemorrhages, comprising, an elongated flexible body, a pair of juxtaposed inflatable bag elements mounted on the outside of the body, said body having a forked terminal portion including separate air passages leading respectively from each branch of the forked terminal portion to the interior of each bag, and valve means in the end of each branch of the forked terminal portion.
