Abstract

According to various embodiments, a medical device may include a hat and an annular securing device coupled to the hat and configured to adjustably secure the hat to a patient'"'"'s body. The annular securing device may be configured to reduce in circumference when at least one end of the annular securing device is pulled in an axial direction. The medical device may also include a sensor disposed on the hat or annular securing device. The sensor may be configured to communicatively couple to the patient'"'"'s body.

Claims

1. A medical device comprising:

a hat;

an annular securing device coupled to the hat and configured to adjustably secure the hat to a patient'"'"'s body, wherein the annular securing device is configured to reduce in circumference when at least one end of the annular securing device is pulled in an axial direction;

a locking device configured to maintain the circumference of the annular securing device when the locking device is locked; and

a sensor disposed on the hat or annular securing device, wherein the sensor is configured to communicatively couple to the patient'"'"'s body.

2. The medical device of claim 1, comprising:

a plurality of adjustment devices coupled to the annular securing device, wherein the plurality of adjustment devices are configured to reduce the circumference of the annular securing device when the plurality of adjustment devices are pulled in an axial direction relative to the annular securing device, to at least partially route through an interior of the hat, to extend from the annular securing device through an open portion of the hat configured to be proximate to a top of the hat when the hat is applied to the patient'"'"'s body, and wherein the annular securing device is disposed in a band of the hat;

wherein the locking device is coupled to the plurality of adjustment devices proximate to the top of the hat, wherein the locking device is configured to maintain the circumference of the annular securing device when the locking device is locked; and

a removal device coupled to the band of the hat or annular securing device, wherein the removal device is configured to increase the circumference of the annular securing device.

3. The medical device of claim 1, comprising:

wherein the locking device is coupled to a top of the hat, wherein the locking device is configured to maintain the circumference of the annular securing device when the locking device is locked, and wherein the annular securing device is disposed throughout the hat; and

a removal device coupled to the hat or the annular securing device, wherein the removal device is configured to increase the circumference of the annular securing device.

4. The medical device of claim 1, comprising:

a plurality of adjustment devices coupled to the annular securing device, wherein the plurality of adjustment devices are configured to reduce the circumference of the annular securing device when the plurality of adjustment devices are pulled in an axial direction relative to the annular securing device, and wherein the annular securing device is disposed in a band of the hat;

wherein the locking device comprises a hook and loop fastener, wherein a first portion of the fastener is coupled to the plurality of adjustment devices, the hat comprises a second portion of the fastener or the second portion is disposed on the hat, and the fastener is configured to maintain the circumference of the annular securing device when the first and second portions of the loop fastener are fastened;

an adjustment index disposed on the hat or the annular securing device, wherein the adjustment index is configured to indicate whether the annular securing device is properly securing the hat to the patient; and

a removal device coupled to the band of the hat or the annular securing device, wherein the removal device is configured to increase the circumference of the annular securing device.

5. The medical device of claim 1, wherein the annular securing device comprises a cylindrical, helically wound braid or a cylindrical biaxial braid.

6. The medical device of claim 1, wherein the annular securing device comprises interwoven warp strands and weft strands.

7. The medical device of claim 1, wherein the sensor comprises a substrate disposed on the hat or annular securing device, an emitter disposed on the substrate, a detector disposed on the substrate, and a cable coupled to the emitter and the detector.

8. The medical device of claim 1, comprising a plurality of adjustment devices coupled to the annular securing device, wherein the plurality of adjustment devices are configured to reduce the circumference of the annular securing device when the plurality of adjustment devices are pulled in an axial direction relative to the annular securing device.

9. The medical device of claim 8, wherein the plurality of adjustment devices comprise strings, threads, filaments, twine, cords, cables, straps, strips, bands, or belts, or any combination thereof.

10. The medical device of claim 1, wherein the locking device comprises a clip or a hook and loop fastener, or any combination thereof.

11. The medical device of claim 1, wherein the hat comprises a neonatal stocking cap.

18. The medical device of claim 1, wherein the sensor comprises a pulse oximetry sensor.

12. A method of operating a medical device, comprising:

applying a hat to a patient'"'"'s body, wherein an annular securing device is coupled to the hat, and wherein a sensor is disposed on the hat or annular securing device;

pulling at least one end of the annular securing device in an axial direction to reduce a circumference of the annular securing device, such that the sensor is communicatively coupled to the patient'"'"'s body; and

placing a locking device on the hat or a plurality of adjustment devices coupled to the annular securing device to maintain the circumference of the annular securing device.

13. The method of claim 12, comprising pulling a plurality of adjustment devices coupled to the annular securing device to reduce the circumference of the annular securing device.

14. The method of claim 12, comprising increasing the circumference of the annular securing device with a removal device coupled to the hat or annular securing device to remove the hat from the patient'"'"'s body.

19. The method of claim 12, wherein the sensor comprises a pulse oximetry sensor.

15. A method of manufacturing a medical device, comprising:

providing an annular securing device on a hat, wherein the annular securing device is configured to adjustably secure the hat to a patient'"'"'s body and to reduce in circumference when at least one end of the annular securing device is pulled in an axial direction;

providing a sensor on the hat or annular securing device, wherein the sensor is configured to communicatively couple to the patient'"'"'s body;

assembling the hat, annular securing device, and sensor to form the medical device;

providing a plurality of adjustment devices on the annular securing device, wherein the plurality of adjustment devices are configured to reduce the circumference of the annular securing device when the plurality of adjustment devices are pulled in an axial direction relative to the annular securing device;

providing a locking device on the hat or the plurality of adjustment devices, wherein the locking device is configured to maintain the circumference of the annular securing device when the locking device is locked; and

providing a removal device coupled to the hat or the annular securing device, wherein the removal device is configured to increase the circumference of the annular securing device.

16. The method of claim 15, comprising providing the annular securing device in a band of the hat.

17. The method of claim 15, comprising providing the annular securing device throughout the hat.
