Abstract
The invention discloses a dura mater outer catheter fixing device which comprises a fixing body. The fixing body comprises a U-shaped structural viscosity fixing portion and a guide portion, the fixing portion is formed by two wing sides and a bottom sides and used for fixing a dura mater outer catheter in a human body, the guide portion is fixedly connected with the U-shaped structural viscosity fixing portion, and the guide portion and the surface of skin of the human body form a passage space used for guiding and holding the dura mater outer catheter. According to spine bending amplitude of the human body, the middle of the fixing body adopts hollow design, and when the catheter is placed, the catheter is placed more distant along the direction of an incision, so that when the spine of a patient moves, the length of the dura mater outer catheter can be prolonged according to needs to buffer so as to prevent tension from being formed to extract the catheter from a dura mater outer cavity, post-operation analgesic effect is guaranteed, and moving of the patient without obvious sufferings at an early stage after the operation is facilitated; and in addition, for the patient needing long-term analgesia, the puncture position is prevented from being contaminated even infected to some extent.
Description
Technical field
The present invention relates to a kind of medical apparatus, particularly a kind of epidural catheter fixture.
Background technology
Epidural space nerve block anesthesia is one of anesthesia of current domestic contrast extensive use, the anesthesia of use the method, must have a conduit to insert epidural space, along with the reach of science, conduit is inserted from anesthesia and is used and extended to Postoperative Analgesia After use.In prior art, be generally by epidural catheter from puncturing hole lead body, and be fixed in external by fixture (being generally medical proof fabric).At present, mainly there is following problem in epidural catheter fixture: 1. normal person is from uprightly completely anteflexion to spinal column, and the increasing length of spinal column adds 8 ~ 10cm left and right, and therefore patient, will tractive epidural catheter in active procedure, even can be pulled out; 2. the material breathability that epidural catheter fixture adopts is at present poor, and owing to being fixed on back, patient lies low, and perspiration is many, and adhesive matter is easy to come off because sweat is moist; 3. because epidural catheter is to be fixed together with puncturing hole, adjusting the epidural catheter degree of depth, and the scale of observation conduit, or sterilization is when puncturing hole, whole adhesive matter need to be torn it down, so just for operator has brought the difficulty using, careless slightly, even can cause the failure of anesthesia of patient or Postoperative Analgesia After.
Therefore, need to improve epidural catheter fixture, adopt unique design, can make patient's spinal column movable time, can extend as required epidural catheter length, prevent from forming tension force conduit is extracted from epidural space.
Summary of the invention
In view of this, the invention provides a kind of epidural catheter fixture, adopt unique design, make it be beneficial to skin heat radiation and perspire, avoid sweat to accumulate and cause that humidity comes off, being convenient to observe the operation such as puncturing hole and depth of catheter simultaneously, and can make patient's spinal column movable time, can extend as required epidural catheter length, prevent from forming tension force conduit is extracted from epidural space.
Further, epidural catheter fixture of the present invention, comprise the fixed body for epidural catheter being fixed on to human body, described fixed body comprises integrated viscosity fixed part and non-sticky guide part, the tubular conduit space that described non-sticky guide part and human body skin surface are formed for guiding and place epidural catheter.
Further, described fixed body is square structure, described viscosity fixed part is the U-shaped structure being made up of both wings limit and base, described non-sticky guide part cross section is domes, its one end is connected with the sealing of described viscosity fixed part base inward flange, and dual-side is corresponding to be one by one connected with inside edge, described viscosity fixed part both wings limit and to extend to top, described viscosity fixed part both wings limit.
Further, described non-sticky guide part is made up of transparent material.
Further, the corresponding human body puncturing hole in described viscosity fixed part base is provided with the observation port for observing puncturing hole and the epidural catheter degree of depth.
Further, described viscosity fixed part is fenestral fabric, and its both wings limit and base are provided with the grid hole for skin heat radiation and perspire.
Further, described grid hole is rhombus.
Further, described fixed body is made up of elastomeric material.
Beneficial effect of the present invention: epidural catheter fixture of the present invention, according to human spine's bending amplitude, in the middle of fixed body, adopt hollow design, in the time placing conduit, the back segment distances of putting of conduit more, like this in the time that patient's spinal column is movable, can extend as required epidural catheter length, play the effect of buffering, preventing from forming tension force extracts conduit from epidural space, guarantee postoperative analgesia, be conducive to just can without obvious misery in the situation that, carry out in early days activity after operation in patients, and to needing long term analgesic patient, also prevented that to a certain extent site of puncture is contaminated, the possibility even infecting, viscosity fixed body adopts latticed design, is beneficial to like this skin heat radiation and perspire, avoids sweat to accumulate and causes that humidity comes off, and is also provided with observation port, is convenient to observe the operation such as puncturing hole and depth of catheter, this apparatus structure also can reduce some medical tangles that may cause in the technical process that eases pain after surgery simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is that structure of the present invention is used schematic diagram;
Fig. 2 is that Figure 1B-B is to view.
Detailed description of the invention
Fig. 1 is structural representation of the present invention, Fig. 2 is that Figure 1B-B is to view, as shown in the figure: the epidural catheter fixture of the present embodiment, comprise the fixed body for epidural catheter being fixed on to human body, it is characterized in that: described fixed body comprises integrated viscosity fixed part 1 and non-sticky guide part 2 the tubular conduit space 7 that described non-sticky guide part 2 and human body skin 8 surfaces are formed for guiding and place epidural catheter 5; In the time placing epidural catheter, epidural catheter how can be put to a segment distance toward puncturing hole direction in channel space, in the time that patient's spinal column is movable, can extend as required epidural catheter length like this, play the effect of buffering, prevent from forming tension force conduit is extracted from epidural space.
In the present embodiment, described fixed body is square structure, the U-shaped structure of described viscosity fixed part 1 for being formed by both wings limit and base, described non-sticky guide part 2 cross sections are domes, its one end is connected with described viscosity fixed part 1 base inward flange sealing, and dual-side is corresponding to be one by one connected with described viscosity fixed part 1 inside edge, both wings limit and to extend to described viscosity fixed part 1 top, both wings limit; U-shaped structure can strengthen the fixed-area of viscosity fixed part, epidural catheter is tightly fixed on to human body skin surface, and simple in structure, easy operating, the guide part that transparent material is made can be observed the distance of epidural catheter toward playback easily, is easy to control conduit playback length; Certainly, guide part is fixedly connected with and also can be alternate manner with viscosity fixed part, as bonding or other detachable connected mode, as long as can realize object of the present invention.
