Abstract

A breathing monitor article of wearing apparel, adapted for child users in order to monitor breathing conditions of a child user. The apparatus and the method of the invention are particularly adaptable for infant child users in order to prevent conditions such as Sudden Infant Death Syndrome and similar conditions arising from apnea. The article of wearing apparel comprises a shirt or like garment adapted to extend around the chest and/or abdomen portion of the child user and which contains a pocket having a monitor therein. An elastic belt extends about the chest and/or abdomen of the user and particularly, in the region of the user'"'"'s lungs. A strain gauge is secured to the elastic belt and detects breathing movement through the expansion and contraction of the chest wall. The monitor is electronically operated and constructed so as to generate an alarm signal if there is a cessation of breathing for a minimum predetermined time period. The shirt, or like garment, is also constructed so that when it is secured to the child user, it automatically energizes the monitor, thereby eliminating the necessity of an attendant to the child from turning the monitor on or off.

Claims

1. An article of wearing apparel having the capability of detecting cessation of breathing in a user for a predetermined minimum period of time and generating an alarm signal, said article comprising:

(a) a chest encircling garment adapted to extend around the chest wall of the user, said garment having an interior pocket and an exterior pocket;

(b) a belt associated with said garment and adapted to encircle a portion of the chest wall of the user, said belt extending into said interior pocket and terminating in said interior pocket;

(c) a gauge associated with said belt for detecting chest wall expansion and contraction and generating a signal in response thereto; and

(d) timing means connected to receive the signal from said gauge for determining if a time period between chest wall expansions exceeds a predetermined time limit to thereby enable monitoring of the breathing condition of the user, and said exterior pocket of said garment holding a monitor that includes said timing means and an alarm signal generating means for generating the alarm signal when said time period between chest wall expansions exceeds said predetermined time limit.

2. The article of wearing apparel of claim 1 wherein the chest encircling garment is adapted to extend fully around the middle or upper torso of the user, the belt is elastic, and the elastic belt is adapted to extend fully around the middle or upper torso of the user.

3. The article of wearing apparel of claim 1, wherein said belt is an elastic belt and said gauge is mounted on said elastic belt and is located in a region of said interior pocket.

4. The article of wearing apparel of claim 1, wherein said monitor is located on the garment such that it is adapted to be located close to a position where said monitor is almost under the armpit of the user.

5. The article of wearing apparel of claim 1 wherein said gauge is a strain gauge.

6. The article of wearing apparel of claim 1, wherein said belt is an elastic belt and amplifies a chest wall expansion of the user.

7. The article of wearing apparel of claim 1, wherein said chest encircling garment comprises fastening means for securing the article about the chest of the user and said fastening means is connected to said monitor to generate an audible signal that the article is in condition for operation when the fastening means is fastened.

8. An assembly for monitoring conditions of apnea in a child user and particularly an infant child user, said assembly comprising:

(a) a shirt-like article of wearing apparel for wearing engagement by the child user, said shirt-like article including an exterior pocket and an interior pocket;

(b) an elastic belt connected to said article of wearing apparel, said elastic belt being stretchable in response to a chest wall expansion of the child user during a breathing cycle of the child user, said elastic belt extending into said interior pocket;

(c) a strain gauge on said elastic belt and generating an electric signal in response to said chest wall expansion of the child user in a breathing cycle, said strain gauge being disposed in close proximity to said interior pocket; and

(d) monitor means connected to said strain gauge for receiving the electrical signal and causing generation of an alarm signal if there is a breathing cessation for a period which could cause injury to the child user, said monitor means being located in said exterior pocket of said shirt-like article.

9. The assembly for monitoring conditions of apnea of claim 8 wherein said monitor means comprises a timing means for determining the occurrence of breathing cycles in a predetermined time period.

10. The assembly for monitoring conditions of apnea of claim 9, wherein an alarm signal generating means for generating the alarm signal is located in said monitor means and is connected to said timing means and causes generation of the alarm signal.

11. The assembly for monitoring conditions of apnea of claim 8 wherein said monitor means causes generation of a warning signal if the assembly is not in a proper condition of use when the article of wearing apparel is first disposed on the child user.

12. The assembly for monitoring conditions of apnea of claim 11 wherein said monitor means generates said warning signal if the assembly should become inoperative while being worn by the child user.

13. An article of wearing apparel having the capability of detecting cessation of breathing in a user for a predetermined minimum period of time and generating an alarm signal, said article comprising:

(a) a chest encircling garment adapted to extend around the chest wall of the user, said garment having a pocket and fastening means for securing the article about the chest of the user and said fastening means is connected to a monitor to generate an audible signal that the article is in condition for operation when the fastening means is fastened;

(b) a belt associated with said garment and adapted to encircle a portion of the chest wall of the user;

(c) a gauge associated with said belt for detecting chest wall expansion and contraction and generating a signal in response thereto; and

(d) timing means connected to receive the signal from said gauge for determining if a time period between chest wall expansions exceeds a predetermined time limit to thereby enable monitoring of the breathing condition of the user, and said pocket of said garment holding said monitor that includes said timing means and an alarm signal generating means for generating the alarm signal when said time period between chest wall expansions exceeds said predetermined time limit.

14. The article of wearing apparel of claim 13, wherein the chest encircling garment is adapted to extend fully around the middle or upper torso of the user, the belt is elastic, and the elastic belt is adapted to extend fully around the middle or upper torso of the user.

15. The article of wearing apparel of claim 13, wherein the pocket is an interior pocket and said belt extends into said pocket and terminates in said pocket.

16. The article of wearing apparel of claim 15, wherein said belt is an elastic belt and said gauge is mounted on said elastic belt and is located in a region of said interior pocket.

17. The article of wearing apparel of claim 15, wherein said belt is an elastic belt and amplifies a chest wall expansion of the user.

18. The article of wearing apparel of claim 13, wherein said monitor is located on the garment such that it is adapted to be located close to a position where said monitor is almost under the armpit of the user.

19. The article of wearing apparel of claim 13, wherein said gauge is a strain gauge.
