the device being indica-ted generally by reference numeral 16.
The device 16 consists of a thin walled flexible envelope 10 having a thin flexible tube 11 connected therewith. The envelope 10 is a distensible body composed of airtight material. The envelope 10 has the capaci-ty to expand to contain approximately 550 cubic centimeters o:E fluid therein and at the same time when in its unexpanded condition, is suf:Eiciently compact and :Elexible that it is capable oE being swallowed by the user.
The tube 11 i s composed o:E a flexible ai.rtight matexial and is sufficiently flexible and of sufficiently small outside diameter that it may be retained in the user's esophagus over an extended period of time, without interfering with the swallowing process and without undue discomfort. At the same time the walls of the tube 11 are sufficiently inelastic as -to be capable of preventin~ expansion of the tube when internal fluid pressure is applied thereto, during use. The envelope 10 has an openin~ therein which provides communication between the inside of the envelope and the bore of the tube 11 at the point of connection of the tube 11 and the envelope 10. The tube 11 is sufficiently firmly connected to the envelope to permit the envelope to be removed from the user's stomach (following removal of the fluids) by applying tension to the end of the tube extending outside the user's body. It has been found that a tube of approximately 36 inches in length having an inside diameter of 4 or 5 French and an outside diameter of 5 to 6 French is suitable for the purpose. Such a tube is of sufficient length that when the envelope is in place in the user's stomach, the end of the tube will protrude from the user's mouth and of sufficiently large bore as to enable water and air to flow therethrough to inflate the envelope. ~t the end 17 of the tube 11 a small plug 12 is removably fitted to the tube 11. Plug 12 is adapted to seal the end of the tube 11 to prevent the escape of fluid from the envelope, during use.
In order to place the device into its operative position, the envelope 10 is swallowed by the user together with a generous quantity of water to assist its passage. The end 17 of the tube 11 remote from the envelope 10 is held in place outside the user's mouth, during this step. When the envelope 10 is in place in the user's stomach 13, water is introduced into the end 17 of -the tube 11 protruding from the user's mouth. This water passes through the tube 11 and into the envelope 10. The amount oE water used may vary from one user to another depending Oll what is most comfortable for the particular user~ It has been Eound that generally a quantity between 200 and 300 cubic centimeters achieves the desired results without undue discomfort. In addition to the water 14, a quantity of air 15 is also introduced into the envelope 10 r via tube 11. The volume of air used may vary between approximately 200 to 300 cubic centimeters. This volume may also be varied to suit the user's comfort, while maintaining the maximum total quantity of air and water in the envelope in the range of approximately 500 to 550 cubic centimeters.
It has been found that the use of air in the envelope provides huoyancy to the envelope which tends to retain it in the upper area of the user's stomach. Such positioning of the envelope together with the pressure against the user's body, created by the fluids in the envelope, tends to give the user a full feeling, thereby reducing his or her desire for food.
AEter the envelope 10 has been filled with fluids~ the plug 12 is inserted into the end 17 of the tube 11. The end 17 of the tube emerging from -the users body may be held in place by a small piece of tape or plastic.
The device 16 is carried by the user in this manner during the period in which he or she desires to reduce food in-take by reducing sensations of hunger.
When it is desired to remove the device 16 the plug 12 is removed and the fluid 14 and 15 in the envelope 10 is removed by suction. The envelope 10 is then removed through the user's mouth by applyin~ ~entle tension to the tube 11.
In the event the envelope should rupture while in place it has been found that the fluids together with any loose pieces of the envelope, will pass from the body during normal bowel movements. The tube and whatever remains of the envelope attached to it may be removed through the user's mouth.
the device being indica-ted generally by reference numeral 16.
The device 16 consists of a thin walled flexible envelope 10 having a thin flexible tube 11 connected therewith. The envelope 10 is a distensible body composed of airtight material. The envelope 10 has the capaci-ty to expand to contain approximately 550 cubic centimeters o:E fluid therein and at the same time when in its unexpanded condition, is suf:Eiciently compact and :Elexible that it is capable oE being swallowed by the user.
The tube 11 i s composed o:E a flexible ai.rtight matexial and is sufficiently flexible and of sufficiently small outside diameter that it may be retained in the user's esophagus over an extended period of time, without interfering with the swallowing process and without undue discomfort. At the same time the walls of the tube 11 are sufficiently inelastic as -to be capable of preventin~ expansion of the tube when internal fluid pressure is applied thereto, during use. The envelope 10 has an openin~ therein which provides communication between the inside of the envelope and the bore of the tube 11 at the point of connection of the tube 11 and the envelope 10. The tube 11 is sufficiently firmly connected to the envelope to permit the envelope to be removed from the user's stomach (following removal of the fluids) by applying tension to the end of the tube extending outside the user's body. It has been found that a tube of approximately 36 inches in length having an inside diameter of 4 or 5 French and an outside diameter of 5 to 6 French is suitable for the purpose. Such a tube is of sufficient length that when the envelope is in place in the user's stomach, the end of the tube will protrude from the user's mouth and of sufficiently large bore as to enable water and air to flow therethrough to inflate the envelope. ~t the end 17 of the tube 11 a small plug 12 is removably fitted to the tube 11. Plug 12 is adapted to seal the end of the tube 11 to prevent the escape of fluid from the envelope, during use.
In order to place the device into its operative position, the envelope 10 is swallowed by the user together with a generous quantity of water to assist its passage. The end 17 of the tube 11 remote from the envelope 10 is held in place outside the user's mouth, during this step. When the envelope 10 is in place in the user's stomach 13, water is introduced into the end 17 of -the tube 11 protruding from the user's mouth. This water passes through the tube 11 and into the envelope 10. The amount oE water used may vary from one user to another depending Oll what is most comfortable for the particular user~ It has been Eound that generally a quantity between 200 and 300 cubic centimeters achieves the desired results without undue discomfort. In addition to the water 14, a quantity of air 15 is also introduced into the envelope 10 r via tube 11. The volume of air used may vary between approximately 200 to 300 cubic centimeters. This volume may also be varied to suit the user's comfort, while maintaining the maximum total quantity of air and water in the envelope in the range of approximately 500 to 550 cubic centimeters.
It has been found that the use of air in the envelope provides huoyancy to the envelope which tends to retain it in the upper area of the user's stomach. Such positioning of the envelope together with the pressure against the user's body, created by the fluids in the envelope, tends to give the user a full feeling, thereby reducing his or her desire for food.
AEter the envelope 10 has been filled with fluids~ the plug 12 is inserted into the end 17 of the tube 11. The end 17 of the tube emerging from -the users body may be held in place by a small piece of tape or plastic.
The device 16 is carried by the user in this manner during the period in which he or she desires to reduce food in-take by reducing sensations of hunger.
When it is desired to remove the device 16 the plug 12 is removed and the fluid 14 and 15 in the envelope 10 is removed by suction. The envelope 10 is then removed through the user's mouth by applyin~ ~entle tension to the tube 11.
In the event the envelope should rupture while in place it has been found that the fluids together with any loose pieces of the envelope, will pass from the body during normal bowel movements. The tube and whatever remains of the envelope attached to it may be removed through the user's mouth.
