Abstract
The utility model relates to a pull internal fixation catheter, which belongs to a medical appliance. The catheter is provided with a round-head outer tube and an inner tube which is sleeved in the outer tube and is in sliding fit with the round-head outer tube, the head ends of the inner tube and the outer tube are fixedly connected into a whole in a bonding mode, a urethral catheterization hole is formed in the tube wall of the inner tube and the outer tube, and a section of axial opening which is radially and uniformly distributed and at least 3 equal lengths is formed in the tube wall of the outer tube below the urethral catheterization hole. The catheter is mainly characterized in that the catheter can be conveniently inserted into the urethra, the internal fixation of the catheter can be realized by manually pulling and pushing the catheter in the urethra, the fixation is firmer, the pain of patients can be reduced, and the labor of nursing staff can be reduced.
Description
What this utility model related to one draws the internal fixation catheter to belong to medical apparatus.
Clinical have a large amount of patients need use the catheter urethral catheterization, at present the catheter that uses mainly contains following several: 1. ordinary urethral catheter, need be fixed on the penis or external genital after inserting urethra, often badly deviate from or slide to stimulate initiation urethra inflammation infection because of fixing with adhesive plaster; 2. air bag or water pocket internally-fixed catheter, its cost height, complicated operation easily leak and cause fixing the failure; 3. the hair style of pestering catheter, it can not insert from urethra, inserts from otch in the time of can only performing the operation, and use is restricted.
This utility model purpose is, provides a kind of one to draw the internal fixation catheter, and that uses can reach the urethral catheterization purpose, can insert urethra again very easily and fix or extract, and eliminates the worn-out sick of above-mentioned all kinds of known catheters.
The technical scheme that adopts that achieves the above object is: this one draws the internal fixation catheter, it is characterized in that having the round end outer tube and be sleeved in the outer tube and the interior pipe that is slidingly matched with it, inside and outside two tube head ends are bonding to be fixed with one and to have the urethral catheterization hole on the tube wall herein, also has one section radial equipartition, at least 3 isometric axial cut-outs on the outer tube wall below the urethral catheterization hole.
Accompanying drawing has provided embodiment.
Fig. 1 is for originally one drawing internal fixation catheter organigram.
Fig. 2 is internal fixation state organigram when drawing the internal fixation catheter to use for basis one.
Fig. 3 is that the A-A of Fig. 2 is to profile.
Further describe below in conjunction with accompanying drawing.By accompanying drawing 1 as seen, this catheter comprises outer tube (1), interior pipe (2), fixedly sebific duct (3) and urethral catheterization medicated cap (4).Being blunt rounded referring to its middle external tube of Fig. 2 (1) head end is the round end outer tube.Interior pipe (2) is sleeved within the outer tube (1), and inside and outside two tube head ends stick with glue bonding fixed being connected as a single entity of agent, and the disjunctor place has the urethral catheterization hole that connects with interior pipe, and viscose glue one body length is generally about 2～3 centimetres.On the outer tube wall below the urethral catheterization hole, also has one section radial equipartition, at least 3 isometric axial cut-outs, referring to having the otch that 4 holostromes cut in this example of Fig. 3, incision length is generally between 15～25 millimeters and is advisable, so that this section outer tube wall has elastic performance, incision is relation movingly with the interior pipe (2) of lower part with outer tube (1), and promptly interior pipe (2) can be moving along outer tube (1) inwall string.Wherein inner and outer pipe all can adopt making such as non-toxic medical plastic, silica gel, and outer tube (1) requires suitably to increase hardness and toughness.Fixedly sebific duct (3) is made of medical sebific duct.External catheter medicated cap (4) can be made of general rigid plastics.
This catheter using method is: after being inserted in the human body urethra when this catheter is state shown in Figure 1, one hand-held interior pipe (2) tail end is fixed, another hold outer tube (1) and fixedly sebific duct (3) to the propelling of sliding of pipe end direction, make outer tube (1) head end have one section of axial cut-outs to around swell, be a mushroom sample shape as shown in Figure 2, because embedding one section caliber expansion of urethra, outer tube increases, as expansion bolt for building and with catheter, be fixed within the human body urethra, then fixedly sebific duct (3) be advanced to outer tube (1) afterbody in case outer tube (1) because of sliding behind the elastic force, fixing sebific duct (3) and in being adhesively fixed with adhesive plaster certainly, outer tube also can.Fixedly sebific duct (3) pusher slip when extracting, interior pipe (2) inwardly pushes away, the outside tractive of outer tube (1) makes this catheter return to state shown in Figure 1 again, then can smoothly it be extracted the human body urethra.
This catheter has characteristics simple in structure, easy to use, that cost is low than known technology, and particularly this inner fixed law is fixed, inserts, extracts conveniently, can reduce the sufferer misery, alleviates nursing staff's work.
Claims (4)
1, one draws the internal fixation catheter, it is characterized in that: have the round end outer tube and be sleeved in the outer tube and the interior pipe that is slidingly matched with it, inside and outside two tube head ends are bonding to be fixed with one and to have the urethral catheterization hole on the tube wall herein, also has one section radial equipartition, at least 3 isometric axial cut-outs on the outer tube wall below the urethral catheterization hole.
2, draw the internal fixation catheter by claim 1 described one, it is characterized in that the incision length of the axial cut-outs on the said outer tube wall is generally 15～25 millimeters.
3, draw the internal fixation catheter by claim 1 described one, it is characterized in that also being set with on the said inner pipe wall a fixing sebific duct.
4, draw the internal fixation catheter by claim 1 described one, it is characterized in that said interior pipe tail end can connect external urethral catheterization medicated cap.
