Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a catheter for flushing bladder blood clots.
Background
The aseptic catheter is a tubular appliance which is made of natural rubber, silicon rubber or polyvinyl chloride materials and is inserted into the bladder through the urethra to drain urine or wash the bladder. According to different structures, the method can be divided into the following steps: the catheter with different structures has different purposes, such as a single-cavity catheter, a double-cavity catheter, a three-cavity catheter and the like. Clinically, indications for indwelling catheters include: 1. patients with urinary retention or bladder outlet obstruction; 2. urinary incontinence; 3. accurately monitoring the urine volume; 4. patients are unable or unwilling to collect urine; 5. patients who need to remain in bed or be forced into position for a long time; 6. perioperative use during surgery.
For some patients with hemorrhagic urinary diseases, large blood clots can be formed in the bladder in a short time to block the catheter due to the large amount of bleeding. At the moment, only a three-cavity catheter can be used for continuously irrigating the bladder, or a syringe is used for pressurizing and sucking the blood clot from the water outlet of the catheter to discharge the blood clot. Because the side hole at the top end of the catheter is smaller, the long axis of the side hole of the traditional catheter is about 5mm, the method is only effective on small blood clots, and can only take out blood clots through direct vision of a cystoscope in an operating room for larger blood clots, even open surgery cuts the bladder to take out blood clots.
Chinese patent document CN203154563U, patent name: bladder clot bedside catheter, application date: 2013.08.28. the bedside bladder clot cleaning catheter comprises a water inlet pipeline and a flushing pipeline, wherein the water inlet pipeline comprises a wedge-shaped plug, a water inlet hose and a water inlet switch attached to the water inlet hose, and the wedge-shaped plug is connected to the end part of the water inlet hose; the flushing pipeline comprises a cleaning channel, a hard catheter shell arranged outside the cleaning channel and a flushing channel penetrating through the hard catheter shell, wherein the flushing channel is separated from the cleaning channel, the flushing channel is communicated with a water inlet hose, the hard catheter shell is provided with a side hole at the top end, the cleaning channel is communicated with the bladder through the side hole, and a bottom port of the cleaning channel is a horn-shaped operation port. The special hard elbow conduit can be conveniently inserted into the male urethra and has better trafficability than a soft catheter; the thick inner diameter of the catheter provides good space for a syringe or vacuum extractor to aspirate the blood clots from the bladder. This scheme pipe side opening is similar with traditional catheter side opening size, is difficult to rush out big clot, and sharp-end elbow angle is uncontrollable, can't fully rush out the clot in the bladder.
In view of the above, there is a need for a catheter that can flush out large blood clots in the bladder and has a controlled tip bend angle.
