The present invention provides a surgical manipulator including a manipulator arm, an end-effector held by the robotic arm, surgical tools held by the end-effector and manipulator joints, particularly right-angle drive devices for transmitting rotational motion in one axis to a perpendicular axis.

Surgical manipulator

The present invention provides a method for measuring a blood analyte concentration of a body part comprising removing a portion or all of the blood from the body part to produce a modified body part, and recording a first absorbance value of the modified body part. This is followed by filling the body part with blood to produce a filled body part, and recording a second absorbance value of the filled body part. A difference spectrum is obtained by subtracting the first absorbance values from the second absorbance values, and a calibration algorithm for the blood analyte is applied to the difference spectrum, thereby measuring the concentration of the blood analyte. Also provided is an apparatus for determining the concentration of a blood analyte of a body part. The apparatus comprising a chamber of a size and shape to receive the body part, where the chamber comprises an element for withdrawing and reintroducing blood from the body part, when the body part is inserted within the chamber. The chamber also comprising one or more than one port for introducing electromagnetic radiation into the chamber and onto that body part, and collecting remaining electromagnetic radiation following interaction with the body part.

Apparatus and methods for compensation of blood volume effects on NIR spectroscopic measurements of blood analytes

A compact device () for non-invasively monitoring concentration levels of blood constituents, including glucose, cholesterol, alcohol, blood gases and various ions. The device includes a finger receptor () having a channel for receiving a finger of a user. The channel has a light entrance and a light exit so that light can be passed from a light source () through a finger located in the channel in a direction generally normal to the finger. Certain heat generating components, including a stable power supply for the device, are external to the device housing so as to reduce heat generation and thereby increase stability of the device. The device includes a communications interface for interacting with a computer. The device can be used for clinical use or for home use and the memory of the computer can be used to assist with record keeping and with dosage calculations.

Compact device for measuring, tissue analytes

The present invention provides a thermally stable reference member comprising, at least one radiation attenuating element and at least one radiation scattering element. The radiation attenuating element comprising at least one aperture for transmission of radiation therethrough. The attenuating and scattering elements placed in series so that radiation transmitted through the reference member passes through each of the attenuating and scattering elements. The attenuating and scattering elements of the reference member may further comprise a thermally stable mount to hold the elements in a selected position relative to each other, and in relation to an instrument, or the elements may be bonded together. The radiation attenuating element may be comprised of a material selected from the group consisting of I, tungsten, brass, and a material substantially non-transparent for incident radiation, and the radiation scattering element may be comprised of a radiation scattering material selected from the group consisting of opalescent glass, S, PTFE, Z, fused silica, quartz, sapphire, diamond, and a transparent material with essentially low thermal expansion.

Electromagnetic radiation attenuating and scattering member with improved thermal stability

The present invention provides an artificial member ( ) which mimics the absorbance spectrum of a body part and includes the spectral components of blood analytes. The artificial member comprises a light scattering and reflecting material, and has a chamber portion comprising one or more chambers ( ). The artificial member is configured to be reproducibly received in a measuring receptor which receptor is operatively connected to a non-invasive monitoring device.

Device for verifying the accuracy of a spectral analyzer

Described is a method and apparatus for determining a diabetic patient's compliance with their insulin dosing regime. The method and apparatus involves taking a blood sample from a patient by a routine finger prick and placing it in a special sample tab which is placed in a spectrophotometer sample housing. The spectrophotometer measures Hb and HbA concentrations and allows for calculating a ratio of HbA to Hb which is indicative of the degree of patient compliance.
