Definitions

  • the invention relates to a device for fixing and sealing a container with an open end face against a lid or detaching the container from the lid, in particular an absorber container for carbon dioxide in a respirator.
  • a ventilator is known from SE-PS 501 729. This document does not describe how the absorber container is fixed and sealed on the ventilator to prevent anesthetic gas from leaking into the surrounding atmosphere or how the container is detached from the ventilator so that saturated absorbent material can be replaced with new material.
  • US Pat. No. 3,794,027 describes an anesthetic machine intended for larger animals.
  • the device is equipped with a cylindrical absorber for carbon dioxide, which is equipped with wheels and is intended to stand on the floor.
  • the container has a neck-shaped opening on its end face. Since the opening is relatively large, the container can be filled with absorption material or emptied of absorption material in a simple manner.
  • the opening is sealed by means of a cork-shaped cover which is pressed into the neck-shaped opening, a sealing ring which is fitted in a groove in the peripheral surface of the cork-shaped cover is and which lies tightly against the surrounding inner wall of the neck-shaped opening, ensures that a good seal of the absorber container can be achieved. Since there is a relatively high friction between the sealing ring and the opening and the design of the cork-shaped cover, it can be difficult to press in or remove the cover.
  • a further absorber container for carbon dioxide is shown in the Siemens instructions for use "Servo Anesthesia Circle 985" for an anesthetic machine.
  • This absorber container is among others provided with a base plate and a housing which can be removed from the base plate and which has a relatively small opening through which the container can be filled with absorption material. The opening is covered with a lid. After a certain period of use, the absorbent material becomes saturated, so that it must be replaced during an operation that takes longer while the patient is under anesthesia. The surgeon must now disassemble, empty, assemble and then fill again with absorption material. This can be time consuming. In addition, fragments of the absorbent material, which is usually lime, may get stuck on the inside wall of the opening when filling, which may result in minor leakage.
  • the invention has for its object to provide a device of the type mentioned, which can quickly release the absorber container so that it can be quickly emptied or filled, and which can fix the absorber container extremely quickly and seal against gas.
  • the cover and the element are fixed on the ventilator.
  • the surgeon can have both hands free to loosen, remove, empty, and fill and fix the container.
  • the means are designed like an annular collar which at least partially surrounds the container, the means being provided with a handle. With the help of the handle, the means can now be easily moved into the end positions mentioned.
  • the means have a thread on the inside and are rotatably arranged along a threaded portion of the container, the threaded portion having at least two, preferably four, thread inputs that are on one level are arranged. This ensures that the means are rotated into the end positions mentioned. Due to a larger number of thread inputs, the rotational movement of the means from one end position to the other is very short. Also done a parallel displacement of the open face of the container in the direction of the lid, the entire surface of the open face being pressed against the lid and fixed gas-tight. The surface of the open end of the container can be cleaned beforehand with a cloth so that it is free of absorption material.
  • the thread inputs are preferably evenly distributed over the circumference of the container. This is a further guarantee that the container will be moved in parallel in the direction of the lid when the means rotate.
  • a favorable embodiment of the invention is obtained in that the threaded section is arranged in the connection on the open end of the container.
  • the container is thereby fixed in the region of its open end face, the groove-shaped opening between the cover and the element being relatively narrow.
  • the lid and element combination on the ventilator does not take up any significant space.
  • the threaded portion can of course be attached to the other closed end of the container, which means that the means are displaceable in this area.
  • the groove-shaped opening is somewhat larger than the height of the container.
  • a further advantageous embodiment of the invention is obtained by the open end face of the container being provided with a flange and a groove running in the flange along this, the means having a peg-shaped part which projects into and runs in the groove when the Means are rotated around the flange.
  • the means run stable in this way when rotating around the container or with respect to the flange.
  • the end face of the flange or the side of the cover directed against the flange can preferably be provided with a rubber seal.
  • a further advantageous embodiment of the invention is provided in that the groove of the flange and the peg-shaped part are mutually arranged such that when the means have been rotated into the first end position, the peg-shaped part is at one end of the groove, and if the means have been rotated to the second end position, the peg-shaped part is located at the other end.
  • the surgeon can quickly access the funds e.g. from a second end position, in which the container is fixed against the cover, to a first end position, in which the container is detached from the cover, and vice versa.
  • the groove is also provided with two nose-shaped constrictions, each of which is arranged at a distance from the ends of the groove which is somewhat larger than the width of the pin-shaped part of the means. This ensures that the means can be locked in the two end positions.
  • the container 1 shows a container for carbon dioxide absorption material.
  • An absorber container for carbon dioxide is in a larger context, i.e. as part of an anesthetic system, described in more detail in connection with SE-C2-501 729.
  • the container 1, which in this exemplary embodiment is cylindrical and made of a transparent material, has an open end face 2.
  • the open end face 2 of the container 1 is provided with a flange 3. Following the flange 3, there is a threaded section, shown and described in more detail in connection with FIG. 3, which has the reference number 4 in this FIG.
  • the container 1 is also provided with an annular collar 5 which partially encloses the container 1, the collar 5 being provided with a thread on the inside and being rotatably arranged along the section 4 provided with the thread.
  • the reason why the collar 5 does not completely enclose the container 1 here is that the container 1 in this exemplary embodiment is provided with an exhalation line 8 which is attached along the outer wall thereof.
  • the outer diameter of the collar 5 corresponds here to the outer diameter of the flange 3.
  • the collar 5 also has a handle 6, so that the operator can use the handle 6 to grip the collar 5 with respect to the flange 3 from a first described in more detail in a later described can turn the second end position.
  • FIG. 1 also shows that the flange 3 is provided with a groove 7 running along it.
  • the collar 5 is provided with a pin-shaped part 9, which is attached exactly in front of the handle 9 and which projects into the groove 7 and runs in the groove 7 when the collar 5 is rotated around the flange 3.
  • a first end position is shown, ie when the collar 5 has been rotated with the aid of the handle 6 into a position in which the collar 5 lies tight against the flange 3.
  • the pin-shaped part 9 is located at one end 10 of the groove 7.
  • FIGS. 1 and 2 shows the collar 5 in a second end position, i.e. when it has been rotated with the aid of the handle 6 into a position in which the collar 5 is mounted at a distance from the flange 3.
  • the pin-shaped part 9 is located at the other end 11 of the groove 7.
  • the groove 7, as has been shown in FIGS. 1 and 2, is provided with two nose-shaped constrictions 12, 13, each at a distance from the ends 10, 11 of the groove 7 are attached, the distance being somewhat larger than the width of the peg-shaped part 9. These nose-shaped constrictions 12, 13 lock the peg-shaped part 9 or the collar when the part 9 is in the mentioned positions and these can only be released from it with a certain amount of force.
  • FIG. 3 shows the threaded section 4 described in connection with FIG. 1 and the collar 5, which is provided with a thread on the inside.
  • the essence of the invention is that the threaded portion 4 and the collar 5, which is internally threaded, have four threaded inputs 14, which are arranged on one level.
  • the threaded inputs 14 are preferably evenly distributed over the circumference of the container 1. Not all thread inputs 14 can be shown in this FIG. Due to this relatively large number of threaded inputs 14, the collar 5 can be shifted from one end position to the other described end position with a relatively small angle of rotation.
  • the collar 5 in this FIG is drawn in such a way that it surrounds the entire container 1, which can be the case if the exhalation line 8 is not arranged along the outer wall of the container 1.
  • FIG 4 which is a plan view of the device according to the invention, a cover 15 for the absorber container 1 is drawn in dash-dot lines.
  • the FIG is to illustrate that the lid 15 is fixed to a respirator 16.
  • An opening 17 for an exhalation line 18 is arranged in the cover 15, so that the exhalation gas of a patient connected to the ventilator 1 can be passed through the absorber container 1 and out via the exhalation line 8.
  • a semicircular element 19 which is L-shaped in profile and forms a groove-shaped opening which is clearly shown in FIGS. 5 and 6.
  • the semicircular element 19 and the groove-shaped opening 20 (FIGS.
  • the exhalation line 8 serves here as a guide piece and is guided into a recess 21 provided for this purpose on the element 19.
  • FIG 5 is the L-shaped element 19, which by its shape, the groove-shaped opening 20 between the Cover 15 and the element 19 forms, clearly shown.
  • This opening 20 is dimensioned such that when the collar 5 is brought into a first end position, ie when the collar 5 is tight against the flange 3, the container 1, as already mentioned, can be inserted into the opening 20, as it is shown in FIG. 5, and, when the collar 5 is brought into the second end position, the flange 3, as shown in FIG. 6, lies gas-tight against the cover 15. If the absorption material is to be replaced, the collar 5 is turned into the first end position, the container 1 being quickly released from the cover 15 and being able to be guided out of the opening 20.
  • the threaded section 4 and the collar 5 can be attached to the closed end of the container 1.
  • the collar 5 can lie in a first end position in the same plane as the closed end of the container 1. In a second end position, the collar 5 lies in a plane which is further away from the open end of the container 1 than the closed end of the container 1.
  • the groove-shaped opening 20 between the cover 15 and the element 19 must then be correspondingly large.
  • the container 1 can be quickly detached from the lid, emptied of absorption material, filled with it and then fastened again gas-tight against the lid 15.
  • the device described can preferably also be used in connection with the fixing and sealing of a so-called bag and bottle container against a lid or the like. can be used with the release of such a container from the lid.
