Description
Technical Field
The utility model relates to the field of maintenance after urology surgery, in particular to a four-cavity catheter for compression hemostasis after prostata operation.
Background
After the operation of the prostate, in order to promote the wound healing and hemostasis, it is theoretically necessary to compress the prostate to stop bleeding.
However, there is no hemostatic device after the operation on the prostate, and conventional hemostatic means such as gauze cannot be directly used.
The method adopted at present is that a catheter with an air sac at the front end is inserted into the bladder of a patient, the air sac is inflated, then the catheter is pulled, the air sac is blocked in the bladder of the patient, and then compression hemostasis is carried out on prostate hemostasis; meanwhile, in order to fix the air bag, a circle of gauze strip is tied on the catheter close to the genital tract opening, and the retraction of the catheter is prevented by blocking the genital tract opening.
The prior method needs to use the sliver, so that not only can contact friction be generated on genitals, but also the tissue of the urethral orifice is easily pulled into the sliver to cause pain.
The conventional catheter is convenient to use, such as application number 2021212414893, and comprises a catheter main body tube, wherein a catheter hole is formed in one end of the catheter main body tube, a drainage port (21) is formed in the other end of the catheter main body tube, and an air bag located at the upper end of the catheter hole is arranged on the catheter main body tube and is mainly used for washing the bladder of a patient, so that the catheter is convenient to use. After the existing operation, the sliver can be used for knotting and limiting on the catheter main body tube.
As another example, the application number: CN202220805927.2, which discloses a floating drainage four-cavity catheter for treating large blood clots in the bladder, provides a floating drainage four-cavity catheter for treating large blood clots in the bladder, comprising a catheter body, wherein a first balloon and a second balloon are arranged on the catheter body, the second balloon is far away from the first balloon, when the catheter body is inserted, the second balloon can be placed at the position of a trigone of the bladder, and the first balloon is placed in a gap between the rear top wall of the bladder and the blood clots in the bladder; the rear end part of the catheter body is provided with a one-way air inflation cavity which is communicated with the liquid discharge channel. According to the utility model, the second balloon is arranged at the position of the trigone of the urinary bladder for compression hemostasis, and the first balloon is arranged in the gap between the rear top wall of the urinary bladder and the blood clot in the urinary bladder, so that the blood clot is prevented from blocking the water inlet and the water outlet of the urinary catheter, and drainage and flushing are convenient; in addition, a unidirectional inflating cavity is arranged at the rear end part of the catheter body, an air bag is arranged on the unidirectional inflating cavity, the air bag is extruded to inflate the unidirectional inflating cavity, and the catheter is dredged by utilizing air.
As another example, the application number: CN201020518156.6 discloses a double-sac four-cavity local administration catheter, which belongs to medical appliances, and comprises a catheter body with a guide head at the front end, wherein the periphery of the catheter body is coated with a bladder air sac and a urethra air sac; the first tube cavity is communicated with the drug injection tube joint and is communicated with the outside of the catheter through a radial small hole at the front part of the catheter body, the second tube cavity is communicated with the bladder air injection tube joint and is communicated with the bladder air bag through a second radial small hole on the catheter body, the third tube cavity is communicated with the urination tube joint and is communicated with the outside of the catheter body through a third radial small hole between the bladder air bag and the urethra air bag, and the fourth tube cavity is communicated with the urethra air bag air injection tube joint and is communicated with the urethra air bag through a fourth radial small hole on the catheter body.
The design is provided with two air bags, one is used for preventing the water inlet and outlet from being blocked, and the other is used for forming a closed space in the urethra and continuously supplying medicine to the urethra. Therefore, when the device is used, the device cannot be used for postoperative hemostasis, the catheter cannot be fixed, and the prostate can be effectively and continuously pressed.
Therefore, even if the device is used, the catheter is knotted by the gauze strip, and the fixing operation is carried out.
