Abstract

The present invention relates to a coupling arrangement for a system for endotracheal ventilation of a patient, which system comprises an endotracheal tube and a manifold (100) configured for allowing ventilation of the patient via said endotracheal tube, which manifold (100) has a first coupling means (300) with an axial extent (400) and with engagement means (330); and which endotracheal tube has a second coupling means (400) with an axial extent and with engagement means (420); wherein the coupling arrangement is configured to produce, when the first (300) and the second (400) coupling means are moved together in the axial 360 direction, a locking engagement between the engagement means (33, 420). The invention is characterised in that the first coupling means (300), in the axial direction, comprises an exterior screw thread (320); and that the second coupling means (400) comprises an exterior abutment face (430); that the coupling arrangement also comprises a disengagement means (350) configured for cooperating with said screw thread (320); and that the disengagement means (350) and the screw thread (320) are configured for allowing an axial movement of the disengagement means (350) from a first position, in which said engagement means (330, 420) are in locking engagement, to a second position in which the disengagement means (350) can influence the abutment face (430) by an axial force for releasing the locking engagement.

Description

    BACKGROUND OF THE INVENTION
  • The present invention relates to a coupling arrangement of the kind described in the preamble to claims 1 and 2. The coupling arrangement can be used for connecting a manifold of the kind described in eg WO98133536 and U.S. Pat. No. 5,487,381 to an endotracheal tube.
  • BRIEF SUMMARY OF THE INVENTION
  • It is commonly known to configure the end of an endotracheal tube with a conically tapering male coupling means that is introduced into a complementarily configured female coupling means on the manifold for establishing a sealing frictional connection. In order to separate the parts from each other it is necessary to produce an axial separation force. This force is typically produced by means of a disengagement means in the farm of a wedge-shaped manifold that is wedged between two protruding flanges located at the end of the female and the male coupling means, respectively. However, it has been found that by use of said manifold in practice, it is difficult for the hospital staff to avoid laterally oriented power influences on the coupling means and thus on the endotracheal tube that has been inserted into the patient with ensuing traumatic consequences for the patient. Besides, the prior art solutions involve a risk that the manifold disappears. In given situations, the latter has entailed that the hospital staff have attempted to separate the coupling means manually, which has, to an even wider extent, traumatically influenced the patient due to laterally oriented power influences.
  • It is the object of the invention to solve the above-mentioned problems by the prior art. As featured in the characterising portions of claims 1 and 2 this is obtained by arranging a thread for a disengagement means on either the manifold or in connection with the endotracheal tube. By the solution thus provided it is ensured that, at any time, the separation force is oriented essentially in the axial direction, and that no power influences occur transversally to the coupling means. Additionally, it becomes possible to avoid that the disengagement means is lost.
  • It is also preferred that the coupling means are configured as male and female parts, respectively, as featured in claims 3 and 4. Preferably the coupling means are configured with engagement means in the form of complementary conical faces whereby it is possible to provide a frictional coupling in conventional manner as such. However, nothing prevents the engagement means from being configured in another manner, eg so as to provide a releasable joining by clipping together the engagement parts while profiting from the resilience of the constituent materials.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • The invention will now be described in further detail with reference to the embodiments shown in the drawing. In the drawing:
  • FIG. 1 illustrates a part of a system for endotracheal ventilation of a patient;
  • FIG. 2 illustrates a manifold in a perspective view and featuring a part of the coupling arrangement according to the invention; and
  • FIG. 3 is a cross sectional view through the coupling arrangement according to the invention, without the disengagement means.
  • DETAILED DESCRIPTION
  • In principle, the functionality of the system shown in FIG. 1 corresponds to the functionality of eg the system described in DK patent application No 32195. The system shown is thus suitable for performing ventilation as well as aspiration of a patient and is thus conventionally designated a ‘closed’ system. A flexible shrouding or pipe coupling 50 is thus, at its first end 52, connected to the valve device 200 and it is, at its opposite end 54, connected to a manifold 100. The valve housing 200 is configured for being, via a coupling 5, connected to a not shown suction device for generating a sub-atmospheric pressure in the system.
  • The manifold 100, which is preferably transparent, is also configured to be connected—via a coupling arrangement—to a tubular element or “tube” for endotracheal ventilation of a patient, ie a tube configured for being introduced into the respiratory tracts of the patient with a view to maintaining artificial ventilation of the patient. To this end, the manifold 100 has a coupling device, designated in the drawing by the reference numeral 300 and to be described in further detail below. An opening 142 in a ventilation stub 141 allows ventilation of the patient by means of a not shown conventional apparatus. To this end the ventilation stub 141 is preferably configured with a screw thread for connection with the ventilation apparatus.
  • Besides, the system conventionally comprises a catheter 40 that extends within the interior of the shrouding 50 and that can be introduced into the patient's respiratory tracts to draw out secretion. At its first end 42, the catheter 40 is securely connected to the valve device 200 and, at its opposite end 44, it is dispiaceably received in the manifold 100, the catheter being—via a packing 104—sealed relative to the shrouding 50 so as to prevent fluid from penetrating into the shrouding. Also, the packing 104 causes secretion to be scraped off the outside of the catheter 40 during withdrawal of the catheter from the patient. it will be understood that the opposite end 44 of the catheter forms a suction point that can, while the shrouding 50 is simultaneously folded, be displaced through the manifold interior and into the not shown tube for ventilation of the patient. By this movement, the end 44 of the catheter is thus conveyed to the right in FIG. 1. Hereby it is possible to perform regular suction of secretion from the patient's respiratory tracts, as the operator connects the system to the suction device by operating an actuator button 210 arranged in the valve housing 200.
  • As mentioned above, the manifold 100 has a coupling device that constitutes a first coupling means 300 of a coupling arrangement 300, 330, 400. This first coupling means is shown more clearly in FIG. 2, from where it will also appear that the manifold 100 defines a through-going axis A. In the embodiment shown the coupling means 300 is constituted by a separate pipe coupling that is configured for being able to be fastened in extension of the manifold 100 via an engagement area 150 on the outside of the manifold 100 and that extends along the axis A. However, the coupling means 300 may very well be formed integrally with the manifold 100. The coupling means 300 has an interiorly extending, through-going passage for ventilation and aspiration of the patient, and it has at its one end a first cylindrical area 310 that continues—via an annular plateau 312 that extends perpendicular to the axis A—into a cylindrical area 315 provided with an exterior thread 320.
  • In FIG. 3, the coupling arrangement is shown in further detail. To the left in the drawing the coupling means 300 thus shown that has, to the extreme right, an annular end edge 317. The passage in the cylindrical area 315 has, as will appear, an evenly increasing interior diameter in a direction away from the manifold 100, whereby it is possible to provide a frictional joint between the first coupling means 300 and a second coupling means 400, which is shown to the right in FIG. 3, and comprising an area 420 that is complementary with the area 315.
  • The second coupling means 400 is, as shown, configured as a cylindrical body with a through-going passage that extends along the axis A like the passage in the first coupling means 300. A tapering area 420 of the second coupling means 400 has an increasing, exterior diameter that has been adjusted in accordance with the change in the interior diameter of the passage within the area 315 in the first coupling means 300. Thereby it is possible to provide a sealing frictional coupling by introduction of the second coupling means 400 into the first coupling means 300. When the manifold 100 is to be connected to an endotracheal tube, said joining of the two coupling means is performed for establishing a very sealing frictional connection. The tapering of the passage within the area 315 and the area 420 can be comprised within the preferred ratio of about I to 40.
  • The second coupling means 400 also comprises a plateau 430 that extends perpendicular to the axis A, which plateau forms a transition between the tapering area 420 and a head portion 410 of the coupling means 400. The head portion 410 can either be solidly connected to the end of an endotracheal tube, or it can be configured for being solidly connected to the end of an endotracheal tube immediately preceding the introduction into the patient of the endotracheal tube. It will be understood that the first coupling means 300 will, in the relevant case, form a female coupling means, whereas the second coupling means 400 forms a male coupling means.
  • Additionally the coupling arrangement comprises the disengagement means 350 shown in FIG. 2 that has an internal thread 360 configured for cooperating with the thread 320. The plateau 312 forms a first end position for the disengagement means 350, since preferably the extent of the disengagement means 350 along the axis A corresponds maximally to the extent of the thread 320 along the axis A.
  • When the second coupling means 400 has been introduced into the coupling means 300, the end edge 317 is preferably in abutment on the plateau 430. In this state, there will preferably be a certain distance between the plateau 430 and the disengagement means 350 that has been screwed onto the area 315. In order to be able, in this state, to perform a separation of the two coupling means, the disengagement means 350 is turned a suitable number of times, whereby the means 350 is displaced and caused to abut on the plateau 430. By carrying out a further manual turning of the disengagement means 350, an axial power influence is generated towards the second coupling means 400. The power influence is oriented in accordance with the axis A and will entail that the second coupling means 400 is released. The pitch of the threads 320, 360 can be selected in accordance with the forces involved, including the ease with which the user must be able to turn the disengagement means 350 in order to achieve the intended separation.
  • Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
