Definitions

  • the present invention relates to an arrangement in apparatus with which a gas or gaseous mixture is spontaneously inhaled or forcefully induced into the respiratory system of a patient; in which the gas or gaseous mixture is taken from a pressurized gas-source and administered to the patient through a face mask or a tracheal tube; and in which valve means are provided for controlling the phase-volume gas flow from the gas source.
  • Apparatus of this kind are used, inter alia, to administer a full anaesthetic to patients undergoing surgery.
  • the anaesthetic is often administered initially through a face mask, which is pressed against the patient's face and covers the externally opening respiratory ducts, i.e. the nose and mouth.
  • the anaesthetist will then quite often transfer from this type of administering mode to one in which the anaesthetic is administered through a tube which enters the tracheal tube, through the nose or mouth of the patient.
  • an object of the present invention is to provide an arrangement in anaesthetic administering apparatus which solves the aforementioned problem and which satisfies this desideratum.
  • this invention consists in an arrangement of the aforementioned kind in which the valve means is located between the face mask, or tracheal tube, and a nipple connected to the gas supply line; in which the valve body of said valve means can be manually manipulated between a first position in which said gas can flow freely to said patient, and a second position in which the gas flow to said patient is fully blocked; and in which the valve body is springbiased towards said second position.
  • valve means As a result of the proposed design and positioning of the valve means according to the invention, it becomes naturally a readily manipulated complement to both face mask arid tracheal tube. In practice, it is unnecessary for the anaesthetist to learn new ways of holding and manipulating the face mask etc., since the positions of the hands and the position of the anaesthetizing equipment while an anaesthetic is being administered are practically the same as before. In normal operation, the valve body or plate is moved by exerting a slight finger pressure or hand pressure thereon.
  • the invention will be now described in more detail with reference to two exemplary embodiments thereof, which shall not be considered to restrict the scope of the invention.
  • Figure 1 illustrates in two parts a first embodiment of valve means according to the invention, the upper part of said Figure showing the position of said valve means in which the supply of gas to a patient is fully blocked, while conversely the lower part illustrates the valve means in a position in which gas can flow to the patient via a tracheal tube.
  • Figure 2 illustrates a second embodiment of the invention.
  • gas or a gaseous mixture is taken from a pressurized source and supplied to an angular inlet nipple 10, from where the gas flows through a valve means 11 detachably connected to the nipple 10.
  • the valve means 11 is, in turn, detachably connected to a face mask 12, arranged to be pressed over the nose and mouth of a patient, in a manner known per se.
  • the illustrated face mask can be replaced with a tracheal tube, such as tube 13 shown in the lower part of Figure 1.
  • the valve means 11 includes a tubular body 14 provided with an upper flange 15 having an opening therein for receiving the detachable nipplecoupling 10, and a lower flange 16 having an opening therein for detachably receiving a conventional face mask 12 or tracheal tube 13.
  • a cylindrical valve element 17 mounted for rotation in the tubular body 14 is a cylindrical valve element 17, one end of which projects beyond the tubular body 14. This protruding end of the valve element 17 is provided with a hand grip 18.
  • the valve element 17 is also provided with mutually opposite openings 19 which in one position permit gas to flow to the face mask 12, and in another position completely block said gas flow.
  • the valve element 17 is spring biased towards its gas-flow blocking position.
  • valve body 11 comprises a plate-like body 20 comprising two detachable parts, the upper part of which exhibits a flange 15 provided with an opening for detachably receiving the nipple ⁇ -coupling 10, and the bottom part of which has a corresponding flange provided with a corresponding opening for detachably connecting the face mask 12.
  • a spring-biased plate 21 is arranged for horizontal movement in the bottom plate of said valve body 11, and is provided with an opening 22 which, in the illustrated position, lies outside the plate-like body 20 and therewith blocks the supply of gas to the mask 12.
  • the valve is opened by applying a light finger pressure to the hand grip 18 or to the plate 21.
  • a light finger pressure to the hand grip 18 or to the plate 21.
  • the nipple-coupling 10 When the anaesthetic is administered through the tracheal tube, the nipple-coupling 10 can be inserted into the flange 16 (and correspondingly in the Figure 2 embodiment) to such an extent that the valve is held in a fully open position. When the tube and the valve are separated, the spring action will cause the flow of gas to be blocked.

Abstract

Dispositif permettant l'inhalation spontanee d'un gaz ou d, un melange gazeux ou leur introduction forcee dans le systeme respiratoire d'un patient. Le gaz ou le melange gazeux provient d'une source de gaz sous pression et est administre au patient par l'intermediaire d'un masque facial (12) ou d'un tube tracheal (13) Une vanne sert a regler l'ecoulement du gaz depuis la source de gaz jusqu'au patient. Selon la presente invention, la vanne (11) est placee entre le masque facial (12), ou le tube tracheal (13), et un raccord (10) connecte a la ligne d'alimentation en gaz. La vanne est connue de maniere telle que la distribution en gaz provenant de cette source puisse etre commandee manuellement de maniere continue, entre un premier etat dans lequel l'ecoulement du gaz vers le patient est completement bloque et un deuxieme etat dans lequel l'ecoulement de gaz est maximum.
