Description

  The present invention generally relates to a technique for placing and fixing a tube such as a drainage tube on a skin surface portion of a patient, that is, a person, and more particularly to an apparatus for fixing the tube to a skin surface portion of a patient, that is, a person.

  It is a known technique to insert a drain tube through the patient's or person's skin, for example, to drain fluid from the patient's or person's body cavity after surgery. As its application, the drain tube is also used to create a vacuum in the body cavity drained by the drain tube. An example of such an application is the treatment of collapsed lungs. In this treatment, the patient's thoracic cavity is evacuated through the pleural drainage tube to attach the patient's lung pleura to the radial pleura. In all drain tube applications, there is a risk that the drain tube will be blocked or twisted as it is bent.

  When the drain tube is evacuated to create a vacuum in the body cavity that is evacuated through the drain tube, it creates a reliable and durable seal at the inlet of the drain tube that penetrates the patient's skin In doing so, further problems arise. Furthermore, a general requirement arises that allows the drainage tube to be secured and the seal to be created in a fast and reliable manner. Traditionally, drainage tubes, such as the pleural drainage tube used to evacuate the chest cavity of a collapsed lung patient, have been fixed and sealed manually. That is, a doctor applying a pleural drainage tube arranges one or more petrolatum-impregnated fillings around the pleural drainage tube at the entrance of the thoracic drainage tube that penetrates the patient's skin, and at the entrance The petrolatum impregnated filling is compressed to produce a seal. Then, the vaseline impregnated filling and the pleural drainage tube are fixed with a plaster.

  The technique of fixing a drainage tube, particularly a drainage tube for exhaustion, for example, a pleural drainage tube, is a complicated and time-consuming operation, requires skill, and further penetrates the patient's skin. The seal at the inlet of the drainage tube leaks and is inappropriate, causing great harm to the patient.

In recent years, various devices for fixing a drainage tube have been proposed, as disclosed in US Pat. No. 4,419,094, US Pat. No. 4,645,492, WO 91/07204, WO 91/17738, and WO 93/25264. Yes. Reference is made to the above patents and patent applications. The above US patent is hereby incorporated by reference. Using these known devices, the base of the drain tube that extends from the patient's body through the device's through passage is bent to form a loop, whereby the distal end of the tube is a piece of plaster. To the patient's skin surface. However, this method creates the potential risk that the tube will become clogged if it is inadvertently bent or folded in half.

On the skin surface, the device is secured by a plaster member from a direction substantially perpendicular to the patient or person's skin surface to a direction substantially parallel to the patient or person's skin surface. In addition, the support member of the device according to the present invention prevents the tube from being blocked by bending the tube from the vertical direction to the parallel direction or by twisting or bending the drainage tube. Meet the main purpose. The basic realization of the present invention is that a drain tube extending substantially perpendicularly from the skin surface of a patient, i.e. a person, is greatly exposed to mechanical shock, which on the one hand produces a twist of the drain tube and on the other hand a drain tube. This is related to the fact that the drainage tube is withdrawn from the intended position inside or on the skin surface of the patient or person to whom the drainage tube is fixed. Furthermore, according to the teachings of the present invention, it has been found that the human body greatly attempts to drain foreign objects such as drainage tubes introduced into the human body. In addition, if the drainage tube is fixed in a direction in contact with the patient's or human skin surface in parallel to the direction perpendicular to the patient's or human skin surface where the drainage tube extends, the drainage from the human body The autonomous discharge of tubes is largely eliminated. Preferably, according to the basic experience of the present invention, the outer surface of the support member is rounded to support a length of tube in a curved shape.

  According to a further embodiment of the invention, the connection member supports the support member, and the plaster member and the support member are joined together by a connection member fixed to the first surface of the plaster member. In order to provide reliable fixation of the device according to the invention, i.e. fixation of the drainage tube to the skin surface of the patient in question, the surface of the connecting member is an adhesive layer for sticking to the skin surface of the patient, i.e. human You may have. Preferably, the adhesive layer of the connecting member is a biologically acceptable and / or compatible adhesive layer, a pharmaceutical grade acrylic adhesive layer or a hydrocolloid layer, and is attached to the surface of the connecting member by an adhesive or an adhesive. It is to be glued. The connecting member may have a rectangular or curved profile, or any shape suitable to achieve the basic objectives of the present invention.

  The plaster member of the device according to the present invention may be any shape that serves the purpose of providing a reliable and durable fixation of the flange portion of the support member to the patient's skin surface. .

  The support member is formed from a sponge-like material that is biologically non-invasive and suitable for wound healing or wound treatment, according to embodiments specifically applied to the pleural drainage tube, through which the drainage tube passes. Has an opening. According to this second embodiment of the present invention, the support member may be attached to the second upper surface of the plaster member, the plaster member having a relatively large through opening, the support member opening being a plaster. It coincides with the opening of the member. The apparatus may further include a sealing unit that seals around the opening of the plaster member with respect to the outer peripheral surface of the drainage tube.

  The device according to the present invention may have fixing means for fixing the drainage tube in a plane substantially parallel to the plaster member. The fixing means may be formed as an integral part of the support member or may have an adhesive strip with a transparent opening. The transparent opening is for checking the correct position of the drainage tube relative to the patient, checking for movement of the tube, and checking the condition of the patient's body opening. If the drainage tube remains improperly positioned with respect to the patient, significant damage can be caused to the patient. When air is inadvertently evacuated subcutaneously, a vacuum created in the cavity, for example, in the treatment of collapsed lungs, creates a significantly dangerous and harmful subcutaneous tumor in large areas of the chest and face.

The opening 414 formed in the hydrocolloid layer 473 has the same size as the opening 444 formed in the plaster member 441, and its diameter is somewhat larger than the diameter of the drainage tube 5, so that the drainage tube 5 is hydrophilic. It can extend through the opening 404 of the device without damaging the colloid layer 473. The opening 424 formed in the member 476 has a diameter that substantially matches the diameter of the drainage tube, while the opening 434 in the membrane 479 is somewhat smaller than the diameter of the drainage tube to provide a sealing effect. . Further, a rigid annular member (not shown) that is gripped by the user to provide a rigid holding means during installation of the device, i.e. when pulling out the drain tube or penetrating through the opening 404 of the device 400. ) May be disposed between the membrane 479 and the lower surface of the plaster member 441.

  The apparatus 400 differs from the embodiment of the present invention shown in FIGS. 10 and 11 in that the support member 450 is formed of three individual members 451, 452 and 453. The members 451 and 453 are formed of a relatively soft foam material, but are bonded to each vertical side of a central member 452 formed of a relatively hard and rigid foam material. The member 452 is provided with an upper round surface, and the surface functions to hold the drainage tube 5 as shown in FIG. The size and shape of the member 452 relative to the members 451 and 453 is such that the member 452 forms a concave groove-like portion 465 of the support member 450. As a result, the members 451 and 453 provide lateral support to the drainage tube 5 when the drainage tube 5 is in the use position as shown in FIG. This point will be described in more detail below.

  The support member 450 further includes a string 480 formed as a flexible band. The string 480 is disposed so as to partially surround the member 452 at the end portion farthest from the opening 404. The string 480 may be screwed through the members 451 and 453 as shown in FIGS. 14 and 15, or may be placed around the central member 452 before the support member 450 is formed as shown in FIGS. Then, it is fixed at a position surrounding the member 452 by fixing at that position with an adhesive. One end 481 of the string 480 may be provided with a protrusion, and the other end 482 may be provided with an opening through which the free end 481 is removably removed by the protrusion.

  The apparatus 400 further comprises an elongated fixed strip 443 having an adhesive and a cover sheet on one side. The cover sheet can be removed to expose the adhesive. One end 446 of the fixing strip 443 extends through a slit-like opening 442 disposed in the plaster member 441 in the vicinity of the opening 444. The upper surface of the end 446 of the fixing strip 443 is in contact with the adhesive material on the lower surface of the plaster member, whereby the fixing strip 443 is fixed to the plaster member 441.

  In use, the drain tube 5 is withdrawn through an opening 404 formed in the device 400 as shown in FIG. Membrane 479 fits hermetically around tube 5, thereby sealing the entrance of the pleural drainage tube to the patient's body. As a result, the device is correctly positioned with respect to the skin surface of the patient or person who surrounds the drainage tube 5 circumferentially. Next, the cover portions 411a and 411b are preferably removed at a time to expose the adhesive layer on the lower surface of the plaster member 441. Thereby, the plaster member 441 can be adhered to the skin surface of a patient, that is, a person. After this step, the drainage tube 5 is manually bent downward to the state shown in FIG. Here, the tube 5 is continuously supported by the round bottom surface of the groove 465 formed by the round top surface portion of the member 452 that forms the center portion of the support member 450. The wall of the groove prevents the drainage tube 5 from moving laterally. In this state, the drainage tube 5 is fixed to the support member by the string 480 and the fixing strip 443. Thereby, it is bent downward and adheres to the upper surface of the support member and the drainage tube 5 again.
