The utility model has the advantages that:
the utility model discloses be provided with cutting seam at catheterization body front end, cutting seam the place ahead blind end is provided with the fracture, connects as an organic wholely through the plastics pole between the disconnection, need carry out endoscope at the catheterization in-process and examine time measuring, through rotating the plastics pole, just can cut off the closed end hank in cutting seam the place ahead, makes the front end of catheterization body form the opening, takes out the plastics pole again at last to the endoscope of being convenient for detects.
The utility model discloses a plastic rod still is as the support skeleton of catheter simultaneously, guarantees that the catheter is in unblocked state.
The utility model has simple structure, reasonable design and convenient use; during the use, fill into lubricated liquid in the stock solution gasbag, when inserting the catheter, lubricated liquid flows from the lubricated liquid export along lubricated liquid water conservancy diversion pipeline, has reduced the insertion resistance who inserts the catheter, has avoided the injury of catheter to the urethra mucosa, reduces the probability of urinary system infection, has strengthened patient's comfort level.
The utility model discloses an oil charge pipe includes first connecting pipe and second connecting pipe, can dismantle the connection between first connecting pipe and the second connecting pipe, inserts the urethra back at the catheter, can take off the second connecting pipe, improves the comfort level in the use.
Detailed Description
The first embodiment:
as shown in fig. 1 and 2, the utility model discloses a catheter body 1 is provided with first flow control valve 10 on catheter body 1, is provided with catheterization hole 14 on the front end lateral wall of catheter body 1, and the rear end is provided with out urine mouth 3, and catheterization body 1 middle part in catheterization hole 14 the place ahead is provided with along the cutting seam 17 of axial arrangement, and cutting seam 17 is along radially running through catheter body 1, and the front end of cutting seam 17 is the enclosed construction.
A plastic rod 18 penetrates through the catheter body 1, a gap is formed between the plastic rod 18 and the catheter body 1 to form a catheter channel, and the rear end of the plastic rod 18 extends backwards out of the catheter body 1; the closed end in front of the cutting seam 17 is provided with a fracture 19, the front end of the plastic rod 18 is connected with the catheter body 1 at two sides of the fracture 19 into a whole, so that the front end of the catheter body 1 is in a closed state, and the catheter body 1 can be smoothly inserted into a urethra.
As a further illustration of the embodiment, the plastic rod 18 and the catheter body 1 on both sides of the fracture 19 can be connected by, but not limited to, medical silica gel glue.
When the endoscope examination is needed in the catheterization process, the fracture 19 at the front closed end of the cutting seam 17 can be twisted off by rotating the plastic rod 18, so that the front end of the catheter body 1 forms an opening, and then the plastic rod 18 is pulled out, so that the lens can extend into the bladder from the front end opening of the catheter body 1 during the endoscope examination.
As a further explanation of the utility model, the contact area of the joint of the front end of the plastic rod 18 and the urethral catheter body 1 at the two sides of the fracture 19 is 0.09-0.16 cm respectively2Tests prove that the contact area within the size range can ensure that the fracture 19 is smoothly disconnected when the plastic rod 18 is rotated.
