THE SINGH SPEECH SYSTEM Patent No. 2,164,424

The Singh Speech System is for both total and partial laryngectomees

 


Screw adjustment to desired sensitivity of flap intended to be set to close automatically from increased pressure of exhaled air as the patient starts to speak.

 

 

Bivalve - normally closed but opens when naturally increased pressure occurs during exhalation, as the patient begins to speak.

A video recording, featuring a long-standing patient, demonstrates the system in use. (Available on request)
  • lung-powered
  • hands-free
  • needs no glue
  • in clinical use since 1984
  • self-retaining; very stable in situ, being held in two axes - so much less likely to be coughed out
  • leak-free; (no need of glue)
  • safe; large external flange prevents accidental inhalation
  • supplied in 5 sizes
  • comfortable and unobtrusive
  • durable and inexpensive
  • easy for the patient to insert and remove
  • easy to clean
  • supplied sterile (fistula valve)
  • radio opaque (except for the tracheostoma valve)
Developed for: Dr. W. Singh FRCS, Edinburgh, Scotland
The Singh Tracheostoma Button is made in a soft, compliant, silicone rubber and has a groove inside the large external flange, into which the Singh Tracheostoma Valve will snap-fit, to give hands-free speech to partial laryngectomees.



For total laryngectomees:
Singh Tracheostoma Valve
with Fistula Valve
 
The Singh Fistula Valve is similar to the Singh Tracheostoma Button (q.v.), through which the patient can breathe, but has a projecting valve that terminates in the oesophagus, through which air can be exhaled when the stoma is occluded, so that total laryngectomees can be restored to lung-powered speech


For partial laryngectomees:
Singh Tracheostoma Valve
with Tracheostoma Button

The Singh Tracheostoma Valve is a flap-valve which can be sensitively adjusted for pressure. It comes in one size and snap-fits into the matching groove within the external flanges of the other components, to replace manual occlusion of the stoma and restore hands-free speech.
