Abstract
The utility model relates to a negative-pressure suction three-cavity aerocyst urethral catheter, comprising a three-cavity tube, wherein the three-cavity tube comprises an aerocyst inlet tube, a main urethral catheterization tube and a bladder irrigation tube. The negative-pressure suction three-cavity aerocyst urethral catheter is characterized in that: an inner cavity of the main urethral catheterization tube is provided with a negative-pressure suction core tube in a penetrating manner; a plurality of supporting blocks are arranged on the inner wall at the back end part of the main urethral catheterization tube in a radial direction; the inner side face of each supporting block is provided with an internal thread which is matched with an external thread at the rear side part of the core tube, so as to fix and screw in and out the core tube; and a negative-pressure sucking device is arranged at the back end part of the core tube. The negative-pressure suction three-cavity aerocyst urethral catheter has the advantages of reasonable design and simple structure. Furthermore, with the adoption of the negative-pressure suction three-cavity aerocyst urethral catheter, urine can flow only in an outward direction but not flows backwards, and all the residual urine can be discharged.
Description
Technical field
This utility model relates to a kind of catheter, a kind of vacuum suction three-cavity air bag catheter of saying so more specifically.
Background technology
For operation back intravesical hemorrhage, need discharge blood as early as possible, stop up bladder in case form blood clot.Treatment measures were with three-cavity air bag catheter bladder irrigation constantly in the past.Because flushing liquor is hung to such an extent that the position is high, pressure is big, so the flushing liquor admission velocity is fast, but the blood clot rate of outflow is slow, causes urinary catheter to stop up through regular meeting.
Summary of the invention
In view of the deficiency that prior art exists, this utility model provides a kind of vacuum suction three-cavity air bag catheter, and this vacuum suction three-cavity air bag catheter is reasonable in design, simple in structure, and the intravesical blood clot in back that helps will performing the operation is apace discharged fast.
To achieve these goals; The technical scheme of this utility model is: a kind of vacuum suction three-cavity air bag catheter; Comprise three lumens, said three lumens is characterized in that by air bag air inlet pipe, the urethral catheterization person in charge and bladder irrigation pipe: the inner chamber that said urethral catheterization is responsible for is equipped with the core pipe that is used for vacuum suction; Said urethral catheterization is responsible on the rearward end inwall and radially is provided with several back-up blocks; The medial surface of said back-up block is provided with the female thread that cooperates with the external screw thread of core pipe rear sides, and in order to the fixing of core pipe and screw-in back-out, the rearward end of said core pipe is provided with negative pressure suction device.
Above-mentioned negative pressure suction device is negative pressure bottle or syringe cylinder.
The utlity model has following advantage: the one, reasonable in design, simple in structure; Adopt back-up block that the urethral catheterization person in charge and core pipe are separated, leave gas and get into the space, can apace the blood clot and the urine that remain in the bladder all be discharged.The 2nd, can not only make urine only to outflow, and not flow backwards, and can all residual urine all be discharged.
Description of drawings
Fig. 1 is the structural representation of vacuum suction three-cavity air bag catheter.
Fig. 2 is the urethral catheterization person in charge and core pipe junction sectional structure sketch map.
Among the figure: 1 is three lumens, and 2 is the air bag air inlet pipe, and 3 are the urethral catheterization person in charge, and 4 is the bladder irrigation pipe, and 5 is negative pressure suction device, and 6 is back-up block, and 7 is negative pressure suction device, and 8 is air bag, and 9 are the air inlet plug.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is done further explanation.
The vacuum suction three-cavity air bag catheter of this utility model; Comprise three lumens 1; Said three lumens 1 are by air bag air inlet pipe 2, the urethral catheterization person in charge 3 and bladder irrigation pipe 4; It is characterized in that: the said urethral catheterization person in charge's 3 inner chamber is equipped with the core pipe 5 that is used for vacuum suction, and said urethral catheterization is responsible for and radially is provided with several back-up blocks 6 on the 3 rearward end inwalls, and the medial surface of said back-up block 6 is provided with the female thread that cooperates with the external screw thread of core pipe rear sides; Fixing and screw-in in order to the core pipe screws out, and the rearward end of said core pipe is provided with negative pressure suction device 7.Adopt this structure that the urethral catheterization person in charge 3 is fixing with core pipe 5, its objective is the introducing of being convenient to extraneous gas, guarantee the concordance of inner and outer air pressure, liquid is flowed out from core pipe 5 smoothly.
Above-mentioned negative pressure suction device 7 is negative pressure bottle or syringe cylinder.
The above is merely the preferred embodiment of this utility model, and all equalizations of being done according to this utility model claim change and modify, and all should belong to the covering scope of this utility model.
Claims (2)
