Problems solved by technology

[0012] None of the prior art surgical tourniquet systems or monitoring devices are capable of detecting the presence of a surgical tourniquet system's pressurized pneumatic cuff when the power required to operate the surgical tourniquet system is not supplied to the system
Furthermore, none of the prior art motorized tourniquet instruments prevents the operator from interrupting the power supply required to operate the tourniquet instrument if the operator initiates an interruption of the power supply while the pneumatic cuff connected to the tourniquet instrument is pressurized

Embodiment Construction

[0020] The embodiments shown are not intended to be exhaustive or to limit the invention to the precise forms disclosed. It was chosen and described in order to explain the principles of the invention and its application and practical use to enable others skilled in the art to utilize the invention.

[0021] figure 1 A hazard monitor 2 configured to monitor the pressure within a tourniquet sleeve 4 placed on a limb 6 is described. The tourniquet instrument 8 inflates the pressure tourniquet sleeve 4 to block blood flow to the limb 6 during the surgical procedure. The tourniquet instrument 8 is pneumatically connected to the tourniquet sheath 4 via the pneumatic tube 10 , the pneumatic tee joint 12 and the pneumatic tube 14 . The tourniquet instrument 8 has several components that are energized during normal surgical procedures, including pressure transducers, pressure displays, time displays, alarms and indicators.

[0022] Such as figure 1 As shown, the hazard monitor 2 i...

Abstract

A hazard monitor (2) for a surgical tourniquet system, comprising: a pressure sensor device (20) for detecting the pressure in a pneumatic tourniquet sleeve (4); an electric power monitoring device (22) for monitoring the tourniquet Power supply of the electrical components of the instrument (8), wherein the tourniquet instrument (8) can be pneumatically connected to the tourniquet cuff (4) to supply pressurized gas to said cuff (4) so ​​that the Pressure is generated in (8); and hazard detection means (28), responsive to pressure sensing means (20) and power monitoring means (22), for operating in the tourniquet (4) when power is not supplied to said components An alarm signal is generated when pressure is detected in the

Description

technical field [0001] The present invention generally relates to devices and methods for monitoring surgical tourniquet systems to detect hazards. The present invention relates more particularly, but is not limited to, to a hazard monitor having detection means for detecting when the power supply required to operate one or more components of the system is not being applied to said components. The pneumatic tourniquet cuff (Cuff) is pressurized and detects whether the tourniquet cuff is pressurized when the operator intends to interrupt the power supply required for system operation. Background technique [0002] Surgical hemostasis systems are commonly used to facilitate surgical procedures by blocking arterial blood flow to an extremity for a period of time sufficient to perform the surgical procedure, thereby enabling the operation to be performed in a dry and bloodless environment. [0003] Published medical literature states that every use of a surgical tourniquet nece...
