[0006] The connecting rod is installed in the balloon lumen, the connecting rod is installed with a connecting barrel at one end, a plurality of expansion sacs for plugging the release holes are installed on the outer side of the connecting barrel, and the connecting barrel is connected with a trachea on one side.

[0007] Preferably, the catheter is connected with a medicine inlet pipe for delivering medicine between the catheter and the trachea.

[0008] Preferably, a plurality of connecting barrels and a plurality of expansion sacs are one-to-one corresponding.

[0009] Preferably, the trachea penetrates one end of the catheter.

[0010] Preferably, the expansion sac is in communication with the connecting barrel lumen, and the expansion sac is made of silica gel material.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] 1. The composite hydrogel drug delivery catheter for endometrial repair is used to send the balloon into the uterus, and then composite hydrogel is sent into the catheter and the trachea through the medicine inlet pipe. The composite hydrogel enters the balloon from the catheter and the trachea, and is released from the release holes on the surface of the balloon to the surface of the endometrium for drug delivery.

[0013] 2. The composite hydrogel administration catheter for endometrial repair, the gas is input into the connecting barrel through the trachea, after the gas enters the expansion sac on the surface of the connecting barrel, the expansion sac is expanded, the expanded expansion sac will block the release hole corresponding to the position of the expansion sac to different degrees, thereby the speed of releasing the drug solution by the release hole is slowed down to different degrees, and the speed is adjusted according to the condition of the patient.
