  • Publication number: 20120109269
    Abstract: The present invention relates to a system for keeping a patient warm, particularly a veterinary patient, during care. An apparatus is provided for delivering conditioned air across a barrier, such as a wire cage, to a blanket arrangement for providing conditioned air to the patient. A first duct and a second duct part are provided either side of the barrier mounted together across the barrier, so a duct is provided for ducting conditioned air across the barrier.

  • Patent number: 7883480
    Abstract: A motion monitoring apparatus and method for monitoring a patient under medical care. A sensor arrangement is provided in the form of a pad which the patient lies on. The sensor arrangement provides a signal which can be monitored to observe motion of the patient and provide an alarm should the motion meet certain predetermined conditions. The invention is particularly applicable for monitoring patients under sedation, recovering from anaesthesia, or in intensive care. The device is particularly useful for veterinary patients.

  • Publication number: 20090301484
    Abstract: The present invention relates to a method and apparatus for delivering medicated fluid or anaesthetic to a patient. An issue, particularly with small patients, is the issue of dead space in an anaesthetic circuit which can lead to hypoxia and difficulty with achieving anaesthesia. An apparatus in accordance with the present invention minimises or eliminates dead space by introducing fresh gas (e.g. containing anaesthetic) proximal to a respiratory opening of the subject's respiratory tract, and inducing a fluid flow to reduce re-breathing of fluid exhausted from the respiratory tract.

  • Publication number: 20090266303
    Abstract: An apparatus for keeping young animals warm, in the absence of their mother, for example. A warm air channel is provided by a pervious envelope which has a warm air feed to it. The envelope is placed in a container or housing for receiving the animals, e.g. a whelping box for puppies. The animals may move to the warm air envelope in order to receive warm air.

  • Publication number: 20090187078
    Abstract: The present invention relates to a light source apparatus for a laryngoscope. The light source apparatus is remotely operated. In an embodiment, it comprises a magnetically operated reed switch. A co-operating magnet in the laryngoscope blade actuates the reed switch when the blade is brought into proximity with the light source apparatus mounted in the laryngoscope handle.

  • Patent number: 6948493
    Abstract: An apparatus for delivering anaesthetic to human or animal patients. The apparatus is an anaesthetic machine which is arranged to mount components of an anaesthetic delivery circuit, and which includes a collector arrangement in the form of a manifold having a plurality of inlets and outlets. The manifold enables a reduction in the number of tubes connecting the various components in an anaesthetic system, which are normally required in prior art anaesthetic machines. The manifold also includes an arrangement which provides a Venturi effect on gas flow, and enables a pressure gauge to be mounted out of a patient breathing circuit. The machine is preferably portable.

  • Patent number: 6939307
    Abstract: The present invention relates to a method and apparatus for monitoring haemodynamic function in animals and humans during anaesthesia and surgery. During anaesthesia and surgery the subject's haemodynamic, respiratory, neuromuscular and neurological functions are monitored as indicators of the condition of the health of the subject. Commonly, variations in blood pressure are used to imply corresponding variations in cardiac output, i.e. good blood pressure equals good cardiac output. The present invention utilizes a device to monitor changes of blood flow in peripheral blood vessels of the subject as an indicator of cardiac output. This is believed to provide a much more accurate indicator.
