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
The epidural space nerve block anesthesia is one of anesthesia of present 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 the anesthesia use and has been extended to the Postoperative Analgesia After use.In the prior art, generally be with epidural catheter outside the puncturing hole lead body, and be fixed in external by fixture (being generally medical proof fabric).At present, mainly there is following problem in the epidural catheter fixture: 1. the normal person is from uprightly fully anteflexion to spinal column, and the increasing length of spinal column adds about 8 ~ 10cm, so the patient is in active procedure, will the tractive epidural catheter, even it can be pulled out; 2. at present the material breathability that adopts of epidural catheter fixture is poor, owing to being fixed on the back, the 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 observing conduit, or sterilization is during puncturing hole, need to tear it down whole adhesive matter, so for the operator has brought the difficulty in the use, careless slightly, even can cause the failure of anesthesia of patient or Postoperative Analgesia After.
Therefore, need to improve the epidural catheter fixture, adopt unique design, in the time of can making patient's spinal column movable, can prolong 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, be convenient to simultaneously observe the operations such as puncturing hole and depth of catheter, and can make patient's spinal column movable the time, can prolong 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 for the fixed body that epidural catheter is fixed in human body, described fixed body comprises integrated viscosity fixed part and non-sticky guide part, and described non-sticky guide part and human body skin surface are formed for guiding and placing the tubular conduit space of epidural catheter.
Further, described fixed body is square structure, the U-shaped structure of described viscosity fixed part for being consisted of by both wings limit and base, described non-sticky guide part cross section is domes, the one end links to each other with the sealing of described viscosity fixed part base inward flange, and dual-side one by one correspondence links to each other with inside edge, described viscosity fixed part both wings limit and extends to top, described viscosity fixed part both wings limit.
Further, described non-sticky guide part is made by transparent material.
Further, the corresponding human body puncturing hole in described viscosity fixed part base is provided with for the observation port of 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 by elastomeric material.
Beneficial effect of the present invention: epidural catheter fixture of the present invention, according to human spine's bending amplitude, adopt hollow design in the middle of the fixed body, when placing conduit, conduit is back put segment distances more, like this when patient's spinal column is movable, can prolong as required epidural catheter length, play the effect of buffering, prevent from forming tension force conduit is extracted from epidural space, guarantee postoperative analgesia, be conducive to early stage behind the operation in patients just can be in the situation that carry out activity without obvious misery, and to need long term analgesic patient, prevented also that to a certain extent the site of puncture is contaminated, even the possibility that infects; The 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 also is provided with observation port, is convenient to observe the operations 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.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is that structure of the present invention is used schematic diagram;
Fig. 2 is that Figure 1B-B is to view.
The specific embodiment
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 for the fixed body that epidural catheter is fixed in 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 placing epidural catheter 5; When placing epidural catheter, can in channel space, put a segment distance to epidural catheter toward the puncturing hole direction more, when patient's spinal column is movable, can prolong 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 consisted of by both wings limit and base, described non-sticky guide part 2 cross sections are domes, the one end links to each other with described viscosity fixed part 1 base inward flange sealing, and dual-side one by one correspondence links to each other with inside edge, described viscosity fixed part 1 both wings limit and extends to top, described viscosity fixed part 1 both wings limit; The U-shaped structure can strengthen the fixed-area of viscosity fixed part, epidural catheter tightly is fixed in the human body skin surface, and simple in structure, easy operating, the guide part that transparent material is made can be observed epidural catheter easily toward the distance of playback, is easy to control conduit playback length; Certainly, guide part is fixedly connected with the viscosity fixed part and also can be alternate manner, such as bonding or other detachable connected mode, as long as can realize purpose of the present invention.
