Emergency Pulmonary Resuscitation Device

Abstract

An emergency pulmonary resuscitation device is described. The device of the present invention provides emergency breathing for use in techniques such as CPR, and is preferably capable of interaction with an automatic external defibrillator. The device is easy to operate and provides feedback so that it may be used by persons without medical training. The device also works through a simple action, making it possible for it to be inexpensively manufactured and widely disseminated.

         5 . The emergency pulmonary resuscitation device of  claim 1 , wherein the receptacle is an endo-tracheal tube. 
     
     
         6 . The emergency pulmonary resuscitation device of  claim 1 , wherein the means for delivering a flow of air comprises a pump. 
     
     
         7 . The emergency pulmonary resuscitation device of  claim 6 , wherein the pump is a diaphragm pump. 
     
     
         8 . The emergency pulmonary resuscitation device of  claim 1 , wherein the means for delivering a flow of air comprises:
 a compressible bag; and   an activator for compressing the bag in a manner which causes the bag to generate a flow of air.   
     
     
         9 . The emergency pulmonary resuscitation device of  claim 1 , wherein the means for delivering a flow of air delivers a constant flow of air. 
     
     
         10 . The emergency pulmonary resuscitation device of  claim 1 , wherein the means for delivering a flow of air delivers an intermittent flow of air. 
     
     
         11 . The emergency pulmonary resuscitation device of  claim 10 , further comprising a switch located outside of the opening, so that when the opening is closed by the user, the switch is depressed; wherein, when the switch is depressed, the means for delivering a flow of air is activated so that it delivers a flow of air. 
     
     
         12 . The emergency pulmonary resuscitation device of  claim 1 , wherein the flow of air has a flow rate of about 600-1500 mL/s. 
     
     
         13 . The emergency pulmonary resuscitation device of  claim 1 , wherein the flow of air has a flow rate of about 1200 mL/s. 
     
     
         14 . The emergency pulmonary resuscitation device of  claim 1 , wherein the opening is closed by the action of a finger of a user of the device. 
     
     
         15 . The emergency pulmonary resuscitation device of  claim 1 , wherein the opening is closed by the action of an automatic valve. 
     
     
         16 . The emergency pulmonary resuscitation device of  claim 1 , further comprising a means for providing instructions to a user controlled by the control system. 
     
     
         17 . The emergency pulmonary resuscitation device of  claim 16 , wherein the instruction are instructions on how to perform emergency breathing with the device. 
     
     
         18 . The emergency pulmonary resuscitation device of  claim 16 , wherein the instructions are delivered so that breaths are delivered to the patient in a manner consistent with an established CPR protocol. 
     
     
         19 . The emergency pulmonary resuscitation device of  claim 16 , wherein the instruction delivered are instructions for performing CPR. 
     
     
         20 . The emergency pulmonary resuscitation device of  claim 1 , wherein the control system may be synchronized with the control system of an automatic external defibrillator, wherein the emergency pulmonary resuscitation device is able to coordinate the delivery of breaths with the delivery of shocks by the automatic external defibrillator. 
     
     
         21 . The emergency pulmonary resuscitation device of  claim 20 , wherein the emergency pulmonary resuscitation device and automatic external defibrillator are coordinated to deliver breaths and shocks consistent with an established CPR protocol. 
     
     
         22 . The emergency pulmonary resuscitation device of  claim 1 , wherein a medicinal gas is added to the flow of air before it is delivered to the patient. 
     
     
         23 . The emergency pulmonary resuscitation device of  claim 22 , wherein the medicinal gas is selected from the group consisting of:
 hydrogen sulfide, nitric oxide, corticosteroids, prednisonc, heliox and albutrol   
     
     
         24 . An emergency pulmonary resuscitation device comprising:
 a pump for delivering a flow of air;   a control system; and   a patient circuit receiving the flow of air, the patient circuit comprising a mask for receiving the flow of air having an opening to relive the pressure in the system;   wherein the mask is applied to a patient in need of emergency pulmonary resuscitation, and the opening is closed for a period of time, causing a breath to be delivered to the patient.
