Abstract
The utility model discloses a urethral catheter used for expanding a urethra. The urethral catheter used for expanding the urethra comprises a urethral catheter, an expanding device and a positioning device. The positioning device is arranged on a first part position of the urethral catheter, the expanding device is arranged on the urethral catheter, and the tube wall of the urethral catheter is provided with an interlayer space. The interlayer space is provided with an axial clapboard, the head end of the urethral catheter is provided with a sealing part protruding in a hemisphere shape, and the middle position of the tail end of the urethral catheter forms a catheterization cavity tube mouth. A lower pipeline extends along the axial direction of the urethral catheter, and gradually bent and folded downwards to form an outer air bag cavity tube mouth close to the tail end position of the urethral catheter. The outer air bag cavity tube mouth carries out fixed position water injection expansion or fixed position gas injection expansion to parts which need expanding, or the outer air bag cavity tube mouth is connected with an electronic air pressure pump so as to carry out a control type expansion. By means of the adoption of a batch-type air inflation method or a batch-type liquid inflation method, on one hand, purposes of expansion of the urethra, treatment of urethrostenosis and prostatic hyperplasia are achieved, and on the other hand, the phenomenon that a mucosa is necrotic due to lacking of blood is avoided, and security and validity of treatment of urethrostenosis are greatly improved.
Description
Technical field
This utility model relates to the medical instruments field technical field, particularly a kind of catheter for dilating urethra.
Background technology
Urethral stricture is the more thorny common disease of Urology Surgery, the row urethral dilatation is a kind of important means that checks and treat, design a kind of both can urethral catheterization, can directly reach simultaneously again the purpose of dilating urethra, treatment urethral stricture or prostate hyperplasia etc. by expansion catheter periphery;
Concrete grammar can more can conveniently be treated by the therapeutic equipment of artificial expansion at intermittence, the employed catheter of Hospitals at Present is made with latex or silica gel tube usually, the function that does not have dilating urethra, because the external diameter of catheter can not change, the too little meeting of doing during design causes managing outer wall and urethra forms the gap, causes urine to omit; Medical personnel's operation is also difficult.
The utility model content
For above-mentioned deficiency, the purpose of this utility model is to provide a kind of reasonable in design, easy to operate, can effectively alleviate patient's misery, and the effective catheter of dilating urethra.
To achieve these goals, the technical scheme that this utility model adopts is: a kind of catheter for dilating urethra, it comprises catheter, extension fixture and positioner, and this positioner is arranged on the stem position of described catheter, and described extension fixture is arranged on the catheter.
The tube wall of described catheter is provided with mezzanine space, this mezzanine space is provided with an axial dividing plate, make the top of mezzanine space form a upper pipeline with separate space, make the bottom of mezzanine space form a lower pipeline with separate space, the head end of catheter is provided with a closure that is hemispherical protuberances, the centre position of tail end forms a urethral catheterization lumen mouth, stem at catheter is provided with a urinary catheter mouth that is connected with its pipeline at least, described upper pipeline extends along the axial direction of described catheter, and upwards be bent to form gradually an interior airbag chamber mouth of pipe near the tail end position of catheter, described lower pipeline extends along the axial direction of described catheter, and is bent to form gradually an outer airbag chamber mouth of pipe downwards in the tail end position near catheter.
Described urethral catheterization lumen mouth is provided with the rubber seal lobe, and the described interior airbag chamber mouth of pipe is provided with the rubber seal lobe, and the described outer airbag chamber mouth of pipe is provided with the rubber seal lobe.
Described positioner comprises an interior swelling bag, and swelling bag is set on the stem of described catheter in this, and is provided with a upper shed that pipeline is connected with interior swelling bag cover at this catheter.
Described extension fixture comprises an outer swelling bag, and this outer swelling bag is set on the described catheter, and this catheter be provided with one can make lower pipeline and should outside the under shed that is connected of swelling bag.
The beneficial effects of the utility model are: design ingeniously, rational in infrastructure, when inserting urethra, dwindle shape because positioner and extension fixture are, can be close on the outer wall of catheter, effectively dwindled the external diameter of catheter, and then alleviated patient's misery; Can effectively catheter be positioned at intravesical by positioner, convenient row location, position expansion action to required expansion, and in process of expansion, adopt batch (-type) inflation or liquid filling method, not only reach the purpose of dilating urethra, treatment urethral stricture, avoid again the phenomenon of mucosa ischemic necrosis, greatly improved safety and the effectiveness for the treatment of, be beneficial to wide popularization and application.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples;
Fig. 1 is structural representation of the present utility model;
The specific embodiment
Embodiment: referring to Fig. 1,
A kind of catheter for dilating urethra comprises catheter 1, extension fixture 3 and positioner 2, and this positioner 2 is arranged on the stem position of described catheter 1, and described extension fixture 3 is arranged on the catheter 1.
The tube wall of described catheter 1 is provided with mezzanine space, this mezzanine space is provided with an axial dividing plate 11, make the top of mezzanine space form a upper pipeline 12 with separate space, make the bottom of mezzanine space form a lower pipeline 13 with separate space, the head end of catheter 1 is provided with a closure that is hemispherical protuberances, the centre position of tail end forms a urethral catheterization lumen mouth 14, stem at catheter 1 is provided with a urinary catheter mouth 15 that is connected with its pipeline at least, described upper pipeline 12 extends along the axial direction of described catheter 1, and upwards be bent to form gradually an interior airbag chamber mouth of pipe 16 near the tail end position of catheter 1, described lower pipeline 13 extends along the axial direction of described catheter 1, and is bent to form gradually an outer airbag chamber mouth of pipe 17 downwards in the tail end position near catheter 1.
Described urethral catheterization lumen mouth 14 is provided with rubber seal lobe 4, and the described interior airbag chamber mouth of pipe 16 is provided with rubber seal lobe 4, and the described outer airbag chamber mouth of pipe 17 is provided with rubber seal lobe 4.
Described positioner 2 comprises an interior swelling bag 21, and swelling bag 21 is set on the stem of described catheter 1 in this, and is provided with a upper shed 22 that pipeline 12 is connected with interior swelling bag 21 covers at this catheter 1.
