BACKGROUND OF THE INVENTION
1. Field of the Invention
The apparatus of the present invention relates to emergency medical procedures. More particularly, the present invention relates to an apparatus that can be assembled to provide a device for establishing an air passage for evacuating air from the chest cavity of a person due to a collapsed lung condition.
2. General Background of the Invention
U.S. Pat. No. 5,546,939, entitled “Emergency Tracheostomy Apparatus” was issued to the present invention on Aug. 20, 1996, for an emergency tracheostomy apparatus. The apparatus as disclosed and claimed in that patent is utilized to perform emergency tracheostomies on patients. The present invention, is an apparatus which addresses an additional problem of air which has accumulated in the body cavity of a person due to a collapsed lung condition, and would establish an air passage for evacuating air from the chest cavity to prevent further injury to the patient.
There is an emergency medical condition which is brought about by a person who may have suffered a collapsed lung. For example, when a collapsed lung is caused by a trauma to the rib cage, not only may the lung collapse, but for example, a rib may pierce the sack surrounding the lungs, which would result in any air which is inhaled by the patient to escape into the body cavity between the exterior wall of the body cavity and the sack surrounding the lungs. If this condition is left unattended, it could result in a potentially fatal outcome. As the air accumulates in the body cavity, the air would put increased pressure on the sack surrounding the patient's heart, which due to this increased pressure, would lead if not attended to properly to heart failure. Although this type of a condition can be easily rectified in the confines of a hospital, if such a condition would occur in a setting where there is no emergency equipment to rectify the situation, death of the patient may be inevitable.
Therefore, there is a need in the medical art for a simple apparatus which can be utilized by a doctor, and carried on his or her person, so that should this emergency medical condition arise, the doctor may act quickly with the use of the apparatus and easily rectify the situation and save the life of the patient.
BRIEF SUMMARY OF THE INVENTION
The apparatus of the present invention solves the problems in the art in a simple and straightforward manner. What is provided is an apparatus for evacuating air from the body cavity of the patient during a collapsed lung condition which includes, an air delivery tube portion which is inserted through the skin and into the wall of the body cavity, the air delivery tube portion of the apparatus include a body portion, a first upper threaded end, and a bore extending through the body portion to accommodate air flow through the air delivery tube; there is also provided a trocar member, including a body portion insertable through the bore of the air delivery tube, with a pointed end partially protruding out of the second lower end of the tube for piercing the body cavity wall during insertion of a portion of the air delivery tube into the body cavity; an extender portion engageable to the first upper end of the air conveying tube after the tube has been inserted into the body cavity and the trocar member has been removed from the air delivery tube, for providing a point of delivering air flow through the air delivery tube from the body cavity of the patient; a valving member on the upper end of the extender portion for allowing one-way flow of air out of the body cavity and for preventing air returning into the body cavity as the patient inhales; a flexible, rubber-like tube insertable through the bore in the body portion in the air delivery tube, one end of the tube insertable into the body cavity, so that the air delivery tube may be removed from the body cavity and the flexible rubber-like tube allow air flow through the tube; a valving member on the outer end of the tube for allowing air flow out of the body cavity but for preventing air flow into the body cavity as the patient inhales.
Therefore, it is a principal object of the present invention to provide an apparatus for evacuating air out of the body cavity in the event that a person has a collapsed lung and air is collecting in the body cavity.
It is a further object of the present invention to provide an apparatus for evacuating air from the body cavity which utilizes a single needle puncture through the skin into the body cavity so that air can be vacated through the air delivery tube of a needle to prevent air pressure from building up within the body cavity;
It is a further object of the present invention to provide an apparatus for treating a condition known as pneumothorax, so that the air may be evacuated from the body cavity, and yet when the person attempts to breathe in order to re-inflate one's lung, a one-way valving means on the apparatus prevents air from flowing back into the body cavity during inhalation;
It is a further object of the present invention to provide an apparatus which may be utilized to evacuate air which may have collected in the body cavity due to a collapsed lung, and allow a rubber tube to be positioned so as to receive the air from the body cavity and yet include a valving means for preventing air from flowing back into the body cavity during inhalation.
It is a further object of the present invention to provide an emergency tracheostomy apparatus which can be carried in one's pocket, easily assembled for use, and easily restored for non-use by the user.
