Definitions

  • ABSTRACT A reanimation device consists of a reanimation bag which is placed on the chest of the patient and which has a tube connected to the lungs of the patient, e.g. by a mouthpiece. When the bag is compressed heart massage may be effected through the bag by the operator. Thus, a single person may carry out resuscitation and heart massage alternately.
  • This invention relates to a reanimation device consisting of a compressible and self-expanding reanimation bag, an adaptation piece for the resuscitation channels, a connection tube between the reanimation bag and the adaptation piece and a double valve for resuscitating the patient as well as a suction valve for air supply to the reanimation bag.
  • mouth to mouth resuscitation can-by used or the patient can be resuscitated via a tube which is led into the wind pipe of the patient.
  • a breathing mask can also be used which seals the mouth and nose tightly from outside. Also the frequency and the depth of the pressing down of the breast bone are sometimes given slightly differently. The principle remains unaltered.
  • the current state of the art is given as follows by Frey, Hugin and Mayrhofer (Lehrbuch fur Anesthesiologie und Wiederbelebung, SpringerBerlin, 1971).
  • the patient is laid on a solid surface, the operator then presses with superimposed wrists with powerful pressure rhythmically vertically on the lower half of the breast bone.
  • the breast bone should be depressed by at least 5 to 7 cm, by means of which, at a frequency 60 to 80 compressions per minute, blood pressure values of 60 to 100 mm Hg can be registered.
  • the patient is alternately resuscitated. If only one assistant is available, then the patient is alternately resuscitated and massaged by this person.
  • the resuscitation device of the type described above is characterised in that the reanimation bag consists of a resiliently elastic material which rapidly returns to its Lil initial position and of which the length of the connection tube corresponds to the distance between an adaptation piece and breast bone in such a fashion that heart massage can be carried out through the bag supported on the breast bone of the patient in a predetermined rhythm, alternating with resuscitation.
  • the reanimation device is characterised by a simple and convenient handling. it also permits, in cases in which a second person is not available for reanimation, for example at the scene of an accident, the carrying out of heart massage and resuscitation with a low degree of effort by a single person.
  • the patient is laid with his back on a hard surface.
  • the nose of the patient is closed air-tightly.
  • the compressible reanimation bag is laid on the lower half of the breast bone of the patient and the adaptation piece, for example a face mask, a mouth piece or an intubator tube is connected with the mouth or the wind pipe, i.e. eventually with the lungs of the patient.
  • the resuscitation bag which is laid on the breast bone of the patient, is pressed together with the fists moved against the breast bone, so that the air in the reanimation bag is pressed out and blown into the patient via the connection tube, the double valve and the adaptation piece.
  • the double valve automatically goes into its out position in which the air from the lungs of the patient is led outward.
  • the person doing the resuscitating now holds the bag in the collapsed condition with his fists and presses with the fists through the flat compressed bag on to the breast bone a few centimetres in the direction of the spinal column and thus effects heart massage.
  • the breast bone is depressed several times, usually 4 times, before the person doing the resuscitation releases the flat compressed bag and lets it return into its starting position.
  • the bag refills via the suction valve with air from outside.
  • the reanimation bag now is in the starting position again so that the operation just described can be repeated.
  • the operation as repeated is carried out to a suitable rhythm as long as necessary.
  • the ratios between the pressing down of the breast bone and the resuscitation of the patient can naturally also be altered.
  • the patient is resuscitated once for a 4 times depression of the breast bone.
  • the reanimation bag By making the reanimation bag of a resilient elastic material it is guarnteed that the bag rapidly returns to its initial position after the release of the pressure. The rapid return of the reanimation bag to its starting position makes it possible for air insufflation to begin directly after heart massage, and no time is lost during filling of the reanimation bag with fresh air.
  • the resilient elastic material which rapidly returns to its starting position can be either rubber or a foam rubber corresponding in its properties to rubber or a plastics material.
  • foam rubber there is to be understood a rubber which is provided with pores closed to the outside and which like normal solid rubber is only deformable by the effect of an outer force, but which cannot be changed in its volume.
  • the reanimation bag preferably has such a thin wall thickness that the person using the bag can still feel the patient sufficiently through the resuscitation bag. Because of this it is simple for the person doing the resuscitation to put the bag in the right place and to exercise the pressure on the breast bone at the right place.
  • the reanimation bag can be a longitudinally or a rotationally symmetric hollow body, which is flattened on its support face.
  • the reanimation bag can however also be block shaped or constructed like a bellows.
  • the restricted dimensional limitations which are encountered in doctors bags can be well accommodated, since block shaped or bellows type bags can easily be collapsed.
  • the reanimation bag according to the invention has a solid plate for localizing the pressure on the breast bone, the pressure can be concentrated on the breast bone and thereby increased.
  • the reamination bag can, according to the invention, have a loop on the side remote from the support surface for grasping by the hand of the person doing the resuscitating.
  • the resuscitaton bag can be held securely in the hand and even with the fists of the person doing the resuscitation during reanimation. Slipping of the hand or the fist from the reanimation bag is thus avoided.
  • the reamination bag can however be provided in place of a loop also with a mushroom shaped knob, which is accommodated between the fingers of one hand laid flat on the bag, wherein the head part of the mushroom shaped knob lies above the fingers.
  • the entry valve for the air feed into the reanimation bag can be combined with the double valve for resuscitating the patient into a single constructional unit.
  • the suction valve for air supply into the reanimation bag is set for a very large air flow, in order to guarantee rapid expansion of the bag.
  • the suction valve is also constructed in this fashion if it is not connected with the double valve to form a single constructional unit.
  • the reanimation device has a matching piece which has a tube on which a first curved element is firmly attached, which can be laid between the teeth and lips of the patient, and on which there is slideably arranged a second curved element, by means of which a clamping device is provided by which the second curved element is pressed on to the lips and can be held firmly.
  • This adaptation piece can be applied without difficulties by a single person.
  • this matching piece can be attached to the patients so solidly without any danger of injury that movement of the adaptation piece and thereby any loss of sealing is avoided. This is of particular importance if only one person is available for reanimation, since any rearrangement of the adaptation piece would require the use of valuable time during the reanimation of the patient.
  • the reanimation device is provided with a double valve serving for the resuscitation of the patient, which has a housing with an opening leading to the outer air, a connection point leading to the patient and a connection point leading to the reanimation bag, which is provided with a tubular stub extending into the housing, on the free end of which are arranged a peripheral flange provided with passage holes and an elastic membrane covering the peripheral flange, which serves for closure of the passage holes of the peripheral flange and of the opening leading to the outer air, wherein the crosssectional area of the tubular stub extending into the housing is the same or greater than the cross-sectional areas of the passage holes of the peripheral flange.
  • the resuscitation valves common in commerce do not work optimally.
  • the excess pressure in the lead from the reanimation bag to the lungs of the patient can hinder the return position of the valve, so that the air breathed out by the patient cannot reach the outside.
  • the fist In order to enable the patient to breathe out, using a known resuscitation valve, after the pressing down of the reanimation bag the fist must be removed again somewhat from the breast bone in order to let the reanimation bag expand a little in order to give a slight suction effect.
  • the reduced pressure arising by means of the slight elastic expansion of the bag lets the bag return into the outward position so that the air can diffuse outwardly from the lungs of the patient.
  • the known resuscitation valves thus lead to a very inconvenient operation and also bring with them the danger that, with inexpert handling, diffusion of the air from the lungs of the patient, before the heart massage, can no longer take place. This can lead to lung rupture and thereby to a critical injury to the patient.

  • the reanimation device has a compressable reanimation bag 1 and a flexible connection tube 3, which is connected via a double valve 4 to an adaptation piece 5 on the breathing passages.
  • the reanimation bag 1 can be filled with air from outside via a suction valve 2.
  • the adaptation piece 5 is a mouth piece which is later described in detail.
  • the adaptation piece 5 can however also be a face mask or an intubator tube.
  • the compressable reanimation bag 1 consists of a resilient elastic material, for example rubber, so that the bag returns rapidly and automatically into its original shape after pressing down and the removal of the pressure exercised by the fists.
  • the volume of the reanimation bag is so arranged that a sufficient quantity of air can be fed to the patient.
  • the reanimation bag preferably has such a volume that on compressing about 300 to 1000 cm of air is pressed out.
  • the reanimation bag can have the form ofa rotation ally symmetric hollow body, which is flatened on its support surface 25.
  • the reanimation bag can however also be formed longitudinally, in a block shape or as a bellows.
  • the reanimation bag has a soft airtight elastic shell 6 which surrounds a resilient elastic material 7 such as rubber, foam rubber or a plastics material having corresponding properties to rubber.
  • the resilient elastic material has the form of a hollow body and preferably only a single wall thickness so that the person doing the resuscitating can feel the anatomy of the patient through the collapsed bag.
  • the reanimation bag can be provided with a sticky layer or a device allowing its fixing which allows the bag to be fixed to the breast of the patient.
  • the reanimation bag furthermore has a solid plate 8 for localizing the pressure on the breast bone.
  • This plate can be applied either within or outside the bag.
  • the plate preferably has a size of about 7 X 2.5 cm and consists of solid plastics material which can be somewhat deformable.
  • connection tube 3 should be so constructed that both for large and for small patients it enables correct positioning of the reanimation bag above the breast bone.
  • a flexible extendable tube about 35 cm long is preferred.
  • the tube should furthermore have a certain stiffness whereby collapsing is hindered. It can be made of a suitable material such as plastics or rubher.
  • the suction valve 2 serves for filling the reanimation bag with air from outside. It is preferably combined with the double valve 4 to a single unit.
  • Air is fed to the patient via the double valve 4, which is preferably located between connection tube 3 and adaptation piece 5 by compressing the bag 1 and the air expelled from the patient is led to atmosphere.
  • This double valve 4 should be easily cleaned. It is therefore advantageous if it can be dismantled and if it consists of an easily cleanable material such as plastics.
  • the adaptation piece 5 in the breathing channels can take any customary construction. It can be a face mask, a mouth piece or an intubator tube, which is led into the wind pipe of the patient.
  • a mouth piece is however particularly preferred which has a tube 9 on to which a curved flange 10 is firmly fixed which is laid between the teeth and the lips and on to which a. curved flange 11 is slideably arranged, which can be pressed on to the lips by means of a clamping or securing arrangement 12 and fixed in position.
  • the tube of the mouth piece can, if desired, be led out via the solidly fixed flange 10.
  • the flanges l0 and 11 are so constructed in size and shape that they guarantee an air tight closure of the mouth.
  • the bent flange 10 is laid between the teeth and lips of the patient and the bent flange 11 which is slideably arranged on the tube is pressed and fixed on the lips by means of the clamping or arresting device 12.
  • the curvature of the flange 10 is suitably less than the human jaw.
  • the curvature of flange 11 is such as to guarantee, in the fixed position, an approximately even distance between the two flanges overall, preferably less than that of flange 10.
  • the flanges can be made of a non-slipping material or can be covered with such, in order that the lips of the patient should not be able to slip out between the flanges.
  • the material should be solid but pliable and easily cleaned and suitably consists of plastics such as polyethylene.
  • Suitable as a clamping or fixing device is any arrange ment which allows fixing of the slideably arranged flange 11 on to the lips.
  • a fixing device which permits it to be used with one hand for fixing the flange 11, e.g. in the form of a tongue or lever type arrangement so that one hand remains free for pressing away the lips on leading the mouth piece into position.
  • the double valve 4 and 4' shown in FIGS. 2 to 4 can be arranged corresponding to FIG. 1 between the connection tube 3 and the adaptation piece 5 or between the reanimation bag 1 and the connection piece 3. If the double valve 4 is arranged in the position shown in FIG. 1 then it is avoided that any stale breathed air remains in the connection tube. By means of this it is guaranteed that fresh air, free from used breathed air, is led to the patient. If however the double valve 4 is arranged between the reanimation bag I and the connection tube 3, then the danger is avoided that any intubator tube used is kinked by the weight of the double valve and the air supply to the patient thereby interrupted. Since in this case used breathed air remains in the connection tube it is desirable to make the crosssection of the connection tube 3 as small as possible for diminishing the quantity of used breathed air remaining.
  • the cross-section of the connection tube 3 can amount for example to 0.8 to 1.5 cm
  • the double valve 4 and 4 shown in FIGS. 2 to 4 consists of a housing 13 which has an opening 14 leading to the outside air and two connection places 15 and 16.
  • Connection place 15 leads to the reanimation bag and connection place 16 leads via the adaptation piece 5 to the patient.
  • the connection place 15 leading to the reanimation bag 1 is provided with a tubular post 17 extending into the housing.
  • a surrounding flange 19 provided with passage holes 18 is provided on the free end of the post 17.
  • An elastic membrane 20 lies around the peripheral flange l9 and the cross-sectional area of the post 17, which is held by means of an elastic ring band 22 in a peripheral groove 21 on the peripheral flange 19.
  • the elastic membrane 20 is pressed against the post 23 which extends into the housing 13 leading from the aperture 14 leading to the outside air, by means of which opening 14 is closed.
  • the compressed air passes along the passage holes 18 and the connection place 16 to the lungs of the patient.
  • the elastic membrane returns to its rest position, wherein it closes the through openings 18 and frees the passage for the used air to be breathed out through the opening 14 leading to the outer air.
  • FIG. 4 a further embodiment of the double valve is shown.
  • the peripheral flange 19' is closed while the elastic membrane 20' has passage holes 18' in the region covering the peripheral flange and is closed at its central portion 24.
  • the double valve according to the invention works as follows: By depressing the reanimation bag 1 air is led to the patient via the connection tube 3 the attachment position and the tubular post 17 which extends into the housing 13, the passage holes 18 and the connection position 16. Since the small cross-sectional area of the tubular post 17 extending into the housing 13 is greater than the total cross-sectional area of the passage holes 18 of the peripheral flange 19, an excess pressure is built up which pushes the elastic membrane against the opening 14 which leads to the outside air. By means of this, on the one hand the passage holes 18 of the peripheral flange 19 are freed so that the air can flow to the patient and on the other hand the opening 14 which leads to the outside air is closed by the elastic membrane 20.
  • the slight cross-sectional area of the tubular post 17 is greater than the total surface area of the passage holes 18 of the peripheral flange 19.
  • the optimum ratio between the slight cross-sectional area of the post 17 and the total cross-sectional area of the passage holes 18 depends on the returning force of the elastic membrane 20. In any case it must be guaranteed that the membrane 20 tightly closes the opening 14 leading to the outer air if air is to be led to the patient.
  • a ratio of the cross-sectional area of the post 17 to the total crosssectional area of the passage holes 18 between 2:1 and 20:1 has shown itself to be suitable. Particularly, a ratio between 3:1 and 6:1 is preferred.
  • the shape and number of the holes or openings 18 in the peripheral flange 19 is of no special significance. There can for example be several e.g. 5 to 20 small holes with a diameter of about 0.5 to 2 mm or a few e.g. l to 4 greater openings, these being circular or slit shaped.
  • the total cross-sectional area of the passage holes 18 in the peripheral flange 19 must, on the other hand, be chosen sufficiently large that not too great a resistance arises to the entry of air, because this would give as a result an unnecessary increase in the power necessary for handling the device.
  • the total cross-sectional area of the passage holes 18 can, for example, lie between 5 and 50 mm
  • the peripheral flange 19 provided with passage holes 18 is generally constructed round and preferably curved slightly convexly towards the opening leading to the outer air, in order that the elastic membrane during breathing out of the patient lies well against the peripheral flange 19 and closes the passage holes 18.
  • the peripheral flange 19 can be made of stainless steel or plastics.
  • the peripheral flange 19 is arranged at a distance from the housing wall 26 in order that the air exiting through the passage holes 18 can easily be led further.
  • the peripheral flange 19 is mounted fixedly on post 17 or removably (e.g. by screwing or fitting).

  • the elastic membrane is removably connected with the peripheral flange by means of the elastic belt 22 which engages in the peripheral groove 21 of the peripheral flange 19, in order that the membrane can easily be exchanged on damage or when it becomes dirty.
  • the membrane 20 is provided with passage holes 18' which are located in the ring area of the membrane 20, which covers the peripheral flange 19 which has no passage openings. 1f the membrane 20' lies against the peripheral flange 19, then the passage holes 18 are closed by the peripheral flange. Also in this construction the slight cross-sectional area of the post 17 must be greater than the total cross-sectional area of the passage holes 18.
  • the tubular post 23 on the opening 14 leading to the outside air effects, on the one hand, a sealing closure of opening 14, and on the other protects the elastic membrane from injury.
  • the distance between the membrane 20 which lies against the peripheral flange 19 and post 23 is so large that the air breathed out by the patient can easily diffuse to outside.

  • the only movable part of the double valve 4, 4 is the elastic membrane 20,20 which is the sealing part.
  • the membrane is cheap to manufacture and can easily be changed. The elastic membrane can thereby be changed simply according to choice alone or together with the peripheral flange 19 and the post 17.
  • the stream of air emerging from the lungs of the patient during breathing out can lead, without difficulty, to slight raising of the membrane 20 lying against the peripheral flange 19, since on the one hand the air coming from the patient enters into the holes 18 from below and exercises a certain pressure from below on the membrane 20 and on the other hand as the air flows from opening 14 a certain suction effect is exercised on the membrane 20. 1f the membrane 20 is somewhat lifted from the peripheral flange 19 during the breathing out, then the clear distance between the membrane 20 and outlet opening 14 diminishes. The diminution of this distance can lead therewith to an undesirable piping tone.
