Description

- 3 Description

The present invention relates to a control device for anesthetic vaporizers such as those used for anesthetizing patients used during surgical procedures.

In general, two or more narcotic gases are available to the anesthetist, e.g. B. Isoflurane, Halothane and others.

One of the objects of the present invention is to ensure that the correct narcotic has been selected while ensuring that the other The vaporizer is locked in the "OFF" position while a vaporizer is in use. The device also provides ensure that the operator can have all of the vaporizers in an "OFF" state as required.

Another object of the invention is to provide an apparatus to provide that is adaptable for physical connection with all of the different types of common Narcotics vaporizers.

Another object of the invention is to provide a good visual display of the operational or non-operational state of each of the evaporators, the visual indicator with the Security control and locking mechanism, which is the subject of this invention, is connected.

Another object of the invention is to provide an adapter for a vaporizer device that is initially incompatible with the control and locking mechanism of the invention where the adapters are quickly and easily connected to such vaporizers by mechanical means.

A basic object of the invention is to provide a security control and locking device for narcotics

Provide damper characterized by: A rod that is rotatably mounted in a support bracket; a variety of C-collars on the rod that are set up for rotation with it is, wherein each C-collar or in cross-section C-shaped collar or collar has a fusifparung; An institution for mounting the support bracket on an array of anesthetic vaporizer tanks; being each the tank has a rotatable control knob that includes a horizontal flat spiral vane, the Spiral vane is adapted so that it can be received in a C-collar on the rod, if the recess of the same so that it is in a horizontal orientation; whereby the C-collar prevents rotation of the control knob when the recess in the C-collar is not in horizontal alignment with the wing.

In Fig. 1 is a security control and locking device indicated generally at 10; this control device is on a support bracket 12 of a pair of Anesthetic vaporizers 14 and 16 attached.

In Fig. 2, the security control and locking mechanism comprises 10 a rotatable rod 18 with a plurality of C-collars around it; three such collars or in cross-section C-shaped collars or collars are numbered in FIG. 2 with the numbers 20, 22 and 24. The rod 18 is rotatably supported by the U-shaped support bracket 26 and includes a rotatable control knob 28 on one of it End a. The knob 28 may have a knurled surface as shown to make it easy for the operator to grasp To have surface.

The U-shaped support 26 is in turn made up of a pair of L-shaped beams 30 and 32 carried, which are adapted to be connected to the bottom of the U-shaped beam 26. As shown in Fig. 2, the bottom of the carrier is provided with a pair of elongated slots 26a and 26b, the supports 30 and 32 therein can be adjusted longitudinally therein by bolts or other suitable means Fastening means and wherein the carriers 30 and 32 allow the locking control device to be releasably fastened to a Anesthetic vaporizer device, as shown schematically in Fig. 1.

At the end of the rod 18 and adjacent to the control button 28 is an indicator collar 34 suitably marked to indicate the position of the security control and locking device indicates. A more detailed description of the function of the indicator collar 34 follows below.

As shown in Fig. 3, an embodiment of the The C-collar 20, the indicator collar 34 and the control button on the rod 18 are shown in an extended configuration. Also shown in FIG. 3 is a spring-loaded one Ball 36, which is built into the end of the indicator collar 34 against the pressure of the spring 38, with the ball 36 against the inner surface of the end of the U-beam 26 is pressed. A multitude of semicircular indentations is on End of the U-beam 26 provided so that when the rod and its associated collars are rotated manually by turning the control knob 28, an audible click is heard by the operator when the ball 36 is in .Each of the indentations provided on the inner surface of the end of the U-beam 26 occurs. The spring loaded one Ball 36 also causes rod 18 to be in the selected position Position remains. It will also be seen that the collars 14 and 34 are rotatable relative to one another on the rod 18 are prevented by adjusting screws 20a and 34a.

Referring to FIG. 2, it will be noted that the collar 20 can be adjusted longitudinally on the rod 18 by loosening the set screw 20c, and a longitudinal recess 20b is provided in the rod 18 to ensure that there is no relative rotation of the collar 20 on the rod 18.

It can be seen from FIG. 4 that the evaporator tank 14 has a flow control button 14a of generally cylindrical configuration, the button having a unitary, horizontal, flat spiral wing 14b extending outward v.d. Base of button 14a on one side thereof. The wing 14b ends in a radial end that is set up to do so is to abut the collar 20 on the rod 18, unless and except that the C-collar 20 becomes rotated until its recess 20a is in horizontal alignment with the wing 14b. In the in Fig. The position shown is the control button 14a in the

"OFF" position and can only be rotated to an open or flow position when the rod 18 is in the direction of the Arrow 18a has been rotated until the recess 20a is aligned horizontally with the wing 14b.

As shown in Fig. 5 in an enlarged view, the control button 28 is by the fingers of an operator 37 and it can be seen that the indicator collar 34 has the identifying inscriptions "Isoflurane" and "Halothane" bears, with the inscriptions in longitudinal alignment with the corresponding recesses of the Control C-collar, the one identified by it Evaporator tanks are connected. Alternatively, a color name can be used, as is the case for each Of course, it is a professional.

In Fig. 6 is an adapter button for use with evaporator tanks shown, which are not equipped with wings 14b located on the circumference and which are easily detachable can be attached to such evaporator tanks by means of bolts 14c and / or adjusting screws 14d.

In operation, it can therefore be seen that the operator can quickly access the anesthetic to be vaporized and convenient way to select by turning the control knob 28 to the appropriate visual setting and that only then can it open the evaporator tank indicated by the collar 34. "Only one evaporator tank at a time can are opened, and referring again to Fig. 2 it can be seen that the recesses in the C-collars 20 and 22a around Are arranged rotated 90 ° on the rod 18, the collar 24 has offset its recess by a further 90 ° from Collar 22. Thus, a setting with all vaporizers in the "OFF" position is also available.
