Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.
As shown in Figure 1, the utility model provides a kind of Novel urethral catheter, including catheter body 1.In the catheter body 1 Upper end be equipped with urethral catheterization hole 11 and circumferential balloon 2, the circumferential balloon 2 is located at the lower section of the urethral catheterization hole 11, and the ring-type Sacculus 2 is arranged around the surrounding of catheter body 1.It include the urethral catheterization chamber being connected to urethral catheterization hole 11 in the inner cavity of the catheter body 1 12 and chamber 13 is rinsed, and the water-injecting cavity 14 being connected to circumferential balloon 2, wherein being connected in the end of the water-injecting cavity 14 filling There is physiological saline and is equipped in the control water pocket 3 of water control valve 31 using water pocket 3 made of rubber material, and on the water pocket 3 The circulation of physiological saline.A water sucting cavity 4, one end end of the water sucting cavity 4 are also connected on the outer wall of the catheter body 1 Head is affixed with the outer wall of the circumferential balloon 2, this part cyclic sacculus 2 opposite with water sucting cavity 4 is puncture portion, the puncture portion Thickness is thicker than the rest part of the circumferential balloon 2.The other end of the water sucting cavity 4 is equipped with dismountable automatic water suction device 5, it is that the puncture needle 51 of cavity structure can puncture the puncture portion of circumferential balloon 2 that the automatic water suction device 5, which includes internal, starting The physiological saline in circumferential balloon 2 can be sucked out automatically for automatic water suction device 5.
Using the above structure, after this catheter being inserted into patient's bladder, water control valve 31 is opened, it can be by the physiology in water pocket 3 Salt water directly passes through water-injecting cavity 14 and squeezes into circumferential balloon 2, and circumferential balloon 2 expands after filling the water, just can be smooth by this catheter It is retained in patient's urethra.This injecting process changes and is drawn water from syringe again to the mode of water-injecting cavity water filling, but directly opens control Water valve 31 directly squeezes into the physiological saline of prepackage in circumferential balloon 2, and the injecting process is simple and fast, and due to water pocket 3 and note Water cavity 14 is affixed, therefore can also avoid the problem that syringe water filling is used to be easy to make liquid leakage in the past.Urethral catheterization chamber 12 can be with It is patient's urethral catheterization by urethral catheterization hole 11, rinsing chamber 13 can be that patient rinses urethra with external flusher.To be retained in urethra Catheter tube drawing when, install automatic water suction device 5 in the tail end of water sucting cavity 4, the puncture needle 51 in automatic water suction device 5 from The puncture portion of circumferential balloon 2 is pierced into, and starts automatic water suction device 5, the physiological saline in circumferential balloon 2 is just by automatic water suction device 5 are sucked out, and automatic water suction device 5 is also detachable, therefore the process to absorb water from circumferential balloon 2, easy to operate, simultaneously It not will cause liquid leakage.
As one of optional embodiment, the physiological saline of 10ml is filled in the water pocket 3.The physiology of 10ml Salt water is the amount for being best suited for patient, after all injecting circumferential balloon 2, neither will cause patient's discomfort, and can smoothly indwelling lead Urinary catheter.
The puncture portion of the circumferential balloon 2 is 0.3cm~0.5cm thicker than 2 rest part of circumferential balloon, and circumferential balloon 2 uses Rubber material is made.During puncture needle 51 is pierced into 2 inside of circumferential balloon from puncture portion, this puncture portion is equivalent to a rubber Plug, puncture needle 51 will not destroy circumferential balloon 2 after being pierced into, liquid caused to leak outside from puncturing hole.
The automatic water suction device 5 is clamped with the water sucting cavity 4, and automatic water suction device 5 is connected to 4 tail end end of water sucting cavity Mouthful, it is easy for installation and removal.
