Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is elaborated.
The visual catheter of one as Figure 1-5, comprises catheter body 10, and the front end of catheter body 10 is provided with the probe 20 stretching into human bladder inside; The inside of catheter body 10 is provided with sleeve pipe 30, is provided with dividing plate 40 between the outer wall of sleeve pipe 30 and catheter body 10, the part between sleeve pipe 30 and the outer wall of catheter body 10 is divided into two passages, is respectively medicine liquid channel 11 and urine passageway 12; Catheter body 10 is provided with fluid injection connection tube 13, water filling connection tube 14 and air bag 15; Fluid injection connection tube 13 is communicated with urine passageway 12 with medicine liquid channel 11 respectively with water filling connection tube 14.
Be provided with transparent visual closedcell 21 in the middle part of probe 20, be provided with circular cylindrical shell 22 in compartment 21, the front end of circular cylindrical shell 22 arranges optical frames assembly 23, and the rear end of circular cylindrical shell 22 is provided with image sensor module 24; Image sensor module 24 is connected with external circuit with plug 26 by wire 25; One end of wire 25 connects image sensor module 24, and the other end stretches out outside catheter body 10 through sleeve pipe 30 and is connected with plug 26; Probe 20 is also provided with the medicine outlet 27 and urine filling mouth 28 that are communicated with urine passageway 12 with medicine liquid channel 11 respectively around visual closedcell 21; Medicine outlet 27 place is provided with unidirectional reflux valve 29.
Probe is stretched into intravesical, the intravesical situation of optical frames assembly 23 observable, by image sensor module 24, wire 25 and plug 26, image is shown on external equipment, thus raising operating accuracy, medicinal liquid and clear water can be injected in urethra by fluid injection connection tube 13 and water filling connection tube 14 during urethral catheterization simultaneously, prevent urinary tract infection.
In the present embodiment, fluid injection connection tube 13 and water filling connection tube 14 tilt to the rear end of catheter body 10, and angle of inclination is 30 ~ 60 °.
In the present embodiment, unidirectional reflux valve 29 comprises major diameter body 29a and minor diameter body 29b; Major diameter body 29a is arranging bell 29e with minor diameter body 29b junction, diameter is less than major diameter body 29a and the ball float 29c being greater than minor diameter body 29b is arranged in major diameter body 29a, is also provided with the filter screen 29d of restriction ball float 29c in this major diameter body 29a.When liquid medicine injection, the impulsive force of medicinal liquid makes ball float 29c away from bell 29e, the proud smooth circulation of medicinal liquid, when not liquid medicine injection, intravesical liquid flows into medicine outlet 27, and the impulsive force of liquid makes ball float 29c be close to bell 29e, thus blocks bell 29e.
