Background
Catheterization is a common clinical nursing operation, and the catheters used are divided into three types, namely single-cavity, double-cavity and three-cavity according to structures. The single-cavity catheter usually has no air bag, only has one channel, is not easy to fix and has short retention time, so the double-cavity catheter and the three-cavity catheter are mainly used for retention catheterization. The tail end of the double-cavity urinary catheter is provided with two cavity channels, the air bag channel plays a role in fixing the urinary catheter, and the drainage channel is used for draining urine; the tail end of the three-cavity urinary catheter is provided with three cavity passages, and a flushing passage is additionally arranged for connecting an injector or an infusion apparatus so as to inject physiological saline or medicines and the like into the bladder.
The general silica gel urinary catheter is retained and replaced for one month, the condition of urinary duct blockage can occur in the period, the blockage is particularly easy to occur in patient groups such as upper urinary tract operation, urinary incontinence and the like, the blockage is mainly caused by hematuria caused by bleeding, flocculent precipitates and the like exist in urine caused by repeated urinary tract infection, and the blocked part is a urinary catheter drainage channel. Generally, the urinary catheter can be dredged by repeatedly squeezing the proximal end of the urinary catheter or flushing the proximal end with normal saline, but the pressure is usually low, so that the requirement of dredging the urinary catheter cannot be met. The use of a sterile syringe for negative pressure aspiration is a simple, inexpensive and efficient means, and there is a clinical lack of a connector that can connect the catheter drainage channel to the sterile syringe.
In summary, the applicant provides a three-way joint for connecting a drainage channel of a catheter, which can be respectively connected with an injector and an infusion apparatus so as to achieve the purposes of dredging and blocking a urinary catheter, injecting a liquid medicine, flushing a bladder, reserving a urine culture specimen and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a three way connection for connecting catheter drainage channel solves the catheter and blocks up and the inconvenient technical problem who gets urine and cultivate the sample of staying.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
the utility model provides a three way connection for connecting catheter drainage channel, the catheter keep somewhere the catheter for three chambeies, three chambeies keep somewhere the catheter and include gasbag pipe, drainage chamber way and wash the pipeline, drainage chamber say and be equipped with the recess, drainage chamber way below be equipped with the gasbag, the gasbag with gasbag pipe be linked together, three way connection's one end be syringe end, one end is transfusion system end, the other end is the link, syringe end include the injection orifice, the injection orifice inwards sunken, transfusion system end include the connector, the connector outwards protruding, the connector on open and to have the feed liquor hole, the link be conical, the outer wall of link is equipped with the bead, the bead with three chambeies keep somewhere the drainage chamber way in the recess phase-match of catheter.
Further limited, the infusion set further comprises a sealing cap which is connected to the injection end and the infusion set end in a sealing mode.
Further limit, the inner wall of the sealing cap is provided with internal threads, the outer walls of the injector end and the infusion apparatus end are provided with external threads, the internal threads are matched with the external threads, the height of the sealing cap is larger than the length of the connector, and the sealing cap is connected firmly through threads.
Further limited, the external thread is standard thread, and the threaded connection is convenient.
Further limit, the three-way joint is made of medical silica gel, the requirement of sterility is ensured,
further limit, the three-way joint is transparent, so that the state of flushing and the state of suction can be conveniently checked.
