Technical Field
The utility model belongs to the technical field of medical instrument, especially, relate to a bladder is washed and is used gasbag catheter.
Background
The bladder irrigation is a method of using a catheter to infuse a solution into the bladder and then draining the infused liquid out by using the siphon principle. When the bladder is flushed, the drainage bag needs to be replaced every time, the existing catheter and the drainage bag are inconvenient to connect, the workload of medical workers at ordinary times is increased, and in addition, the needle head connected with the bladder flushing infusion apparatus is high in danger.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem and provides a balloon catheter for bladder irrigation.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a balloon catheter for bladder irrigation comprises a catheter, wherein a drainage tube is arranged in the catheter, a balloon is arranged at the front part of the catheter, and a cavity between the catheter and the drainage tube is divided into an irrigation cavity and a balloon cavity in the catheter; the front end of the catheter is provided with a flushing fluid outlet communicated with the flushing cavity, and the tail end of the catheter is provided with an injection pipe joint communicated with the flushing cavity; a urine inlet communicated with the flushing cavity is arranged between the front end of the catheter and the air bag on the drainage tube, and a drainage bag joint communicated with the drainage tube is arranged at the tail end of the catheter; the front end of the air sac cavity channel is communicated with the air sac, and the tail end of the catheter is provided with an inflation connector communicated with the air sac cavity channel.
Preferably, the rear end of the catheter is provided with a sealing ring and a sealing ring connecting piece for fixing the sealing ring, the sealing ring is sleeved on the drainage tube and blocks a gap between the drainage tube and the catheter, and the sealing ring connecting piece is in threaded connection with the drainage bag connector.
Preferably, a first guide hole and a second guide hole are formed in the catheter along the axial direction of the catheter between the balloon and the injection tube connector, the first guide hole and the second guide hole are communicated with the flushing cavity, and the first guide hole and the second guide hole are arranged close to the balloon.
After the technical scheme is adopted, the utility model has the advantages of as follows:
the utility model discloses add syringe joint, drainage bag joint, inflation joint, the syringe of being convenient for, drainage bag, inflation equipment and catheter be connected, it is convenient to change the drainage bag, and has removed from and use the bladder to wash the syringe needle that the transfusion system is connected, dangerous reduction.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figures 1-2, the balloon catheter for bladder irrigation comprises a catheter 1, a drainage tube 2 is arranged in the catheter 1, and a balloon 3 is arranged at the front part of the catheter 1. The cavity between the catheter 1 and the drainage tube 2 is divided into a flushing cavity 4 and a balloon cavity 5 in the catheter 1.
The front end of the catheter 1 is provided with a flushing fluid outlet 6 communicated with the flushing cavity 4, and the tail end of the catheter 1 is provided with an injection pipe joint 7 communicated with the flushing cavity 4; a urine inlet 8 communicated with the flushing cavity 4 is arranged between the front end of the catheter 1 and the air bag 3 on the drainage tube 2, and a drainage bag joint 9 communicated with the drainage tube 2 is arranged at the tail end of the catheter 1; the front end of the balloon cavity 5 is communicated with the balloon 3, and the tail end of the catheter 1 is provided with an inflation joint 10 communicated with the balloon cavity 5.
The rear end of catheter 1 is equipped with sealing washer (not shown) and is used for fixing the sealing washer connecting piece 11 of sealing washer, the sealing washer cover is established on drainage tube 2 and the shutoff drainage tube 2 with the clearance between the catheter 1, sealing washer connecting piece 11 with drainage bag connects 9 threaded connection.
A guide hole I12 and a guide hole II 13 are arranged on the catheter 1 along the axial direction of the catheter 1 between the balloon 3 and the injection pipe joint 7, the guide hole I12 and the guide hole II 13 are communicated with the flushing cavity 4, and the guide hole I12 and the guide hole II 13 are arranged close to the balloon 3.
The application method of the balloon catheter for bladder irrigation comprises the following steps:
washing: connecting an injection pipe with flushing fluid with an injection pipe connector 7, injecting the flushing fluid into the flushing cavity 4, and enabling the flushing fluid to flow into the bladder from a flushing fluid outlet 6 so as to flush the bladder;
drainage: the drainage bag is connected with a drainage bag connector 9, the inflation equipment is connected with an inflation connector 10, the air bag 3 is inflated through the air bag cavity 5, the air bag 3 expands the bladder and seals the flushing cavity 4, and urine enters the drainage tube 2 from the urine inlet 8 and enters the drainage bag through the drainage tube 2;
and (3) pulling out the catheter: the injection tube with the medicament is connected with the injection tube joint 7, the medicament is injected into the flushing cavity 4, the medicament flows into the bladder from the flushing fluid outlet 6 and flows into the urethra from the guide hole I12 and the guide hole II 13, the friction drag generated by the outer surface of the catheter 1 and the urethra of the patient can be reduced, the pain of the patient when the catheter is pulled out is relieved, and the inflammatory reaction of the local mucous membrane of the urethra of the patient is relieved.
In addition to the preferred embodiments described above, other embodiments of the present invention are also possible, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope of the present invention defined by the appended claims.
