Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, in particular to a silicone urinary catheter. Background Art

[0002] A urinary catheter is a medical device used to guide urine out of the bladder. One end is inserted into the patient's bladder, and the other end is connected to a collection bag or pipe to collect the urine. Urinary catheters are usually used in cases where long-term bed rest is required, after surgery, or when there is bladder dysfunction.

[0003] In the existing related technologies, there are often the following defects: during the actual use of the urinary catheter, when the patient is older, the patient's skin will be relatively loose. After the urinary catheter is inserted, the urinary catheter is likely to shake at the position of the patient's urethra, which easily leads to the phenomenon of dripping and leakage of urine at the position where the urinary catheter is inserted, reducing the performance of the urinary catheter.

[0004] Therefore, the utility model provides a silicone urinary catheter. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantage that it is inconvenient to use a urinary catheter to stably catheterize an elderly patient in the prior art, and a silicone urinary catheter is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a silicone urinary catheter, including a main tube, a first connector is fixedly installed on the end side of the main tube, a docking tube is fixedly installed at the other end of the main tube, a side tube is communicated with the side wall of the docking tube, a shrink film is fixedly installed on the side wall of the side tube, a valve is installed at the port of the side tube, a second connector is detachably installed on the end side of the first connector, a catheter is fixedly installed on the side wall of the second connector, two urine drainage holes are opened on the side wall of the catheter, both the main tube and the catheter are made of silicone material, a fixing cylinder is fixedly installed on the side wall of the catheter, a fixing ring is fixedly connected to the side wall of the fixing cylinder, a plurality of toughness wires are uniformly and fixedly connected to the end side of the fixing ring, a limiting ring is sleeved outside the fixing cylinder, and the other ends of the limiting ring and the plurality of toughness wires are fixedly connected.

[0007] The effect achieved by the above components is that the distance between the limiting ring and the fixing ring will be shortened, and a plurality of toughness wires will be compressed and arched.

[0008] Preferably, a silicone sleeve is adhesively bonded to the outer surface of the catheter, and a chamfer is provided at the end side of the silicone sleeve.

[0009] The effect achieved by the above components is that the silicone sleeve will bulge and support on the inner side of the urethra, thereby improving the stability of the catheter during use after being inserted into the urethra.

[0010] Preferably, an external thread is provided on the outer side of the fixed cylinder, and a threaded ring is threadedly connected to the surface of the external thread on the fixed cylinder.

[0011] The effect achieved by the above components is that when the threaded ring on the outer surface of the fixed cylinder is rotated, the threaded ring will drive the limiting ring to move on the outer side of the fixed cylinder.

[0012] Preferably, anti-slip lines are provided on the side wall of the threaded ring.

[0013] The effect achieved by the above components is that the anti-slip lines on the threaded ring increase the friction between the hand and the outer side of the threaded ring.

[0014] Preferably, two guide blocks are fixedly connected to the inner side of the limiting ring, a guide groove is provided on the side wall of the fixed cylinder, and the guide blocks are slidably connected to the inner wall of the guide groove.

[0015] The effect achieved by the above components is that the guide blocks on the inner side of the limiting ring slide inside the guide groove, which plays a role in restricting the moving direction of the limiting ring.

[0016] Preferably, a plurality of connecting pins are fixedly connected to the end side of the threaded ring, and balls are clamped inside the connecting pins.

[0017] The effect achieved by the above components is that during the process of rotating the threaded ring, the balls of the connecting pins will roll on the end side of the limiting ring, reducing the friction during the relative movement between the threaded ring and the limiting ring.

[0018] In summary:

[0019] In the present utility model, by providing the above structure, it is convenient to inflate the position of the catheter head according to the degree of skin relaxation of the patient, avoiding the phenomenon that the catheter shakes at the position of the patient's urethra, and improving the stability of the catheter during the catheterization process at the position of the patient's urethra.

[0026] Refer to Figures 1-5 As shown, the present utility model provides a technical solution: a silicone urinary catheter, including a main tube 5, a first connector 6 is fixedly installed on the end side of the main tube 5, a docking tube 4 is fixedly installed at the other end of the main tube 5, a side tube 3 is communicated with the side wall of the docking tube 4, a shrink film 2 is fixedly installed on the side wall of the side tube 3, a valve 1 is installed at the port of the side tube 3, a second connector 7 is detachably installed on the end side of the first connector 6, a catheter 8 is fixedly installed on the side wall of the second connector 7, two urinary catheterization holes 9 are opened on the side wall of the catheter 8, and both the main tube 5 and the catheter 8 are made of silicone material.

[0027] The following specifically describes its overall specific settings and functions.

[0028] In this embodiment: a fixed cylinder 11 is fixedly installed on the side wall of the catheter 8, a fixed ring 12 is fixedly connected to the side wall of the fixed cylinder 11, a plurality of tough wires 13 are evenly fixedly connected to the end side of the fixed ring 12, a limit ring 14 is sleeved outside the fixed cylinder 11, and the other ends of the limit ring 14 and the plurality of tough wires 13 are fixedly connected. The distance between the limit ring 14 and the fixed ring 12 will be shortened, and the plurality of tough wires 13 will be compressed and arched. A silicone sleeve 10 is adhesively bonded to the outer surface of the catheter 8, and a chamfer is provided at the end side of the silicone sleeve 10. The silicone sleeve 10 will bulge and support inside the urethra, thereby improving the stability of the catheter 8 when inserted into the urethra for use.

[0029] External threads are opened on the outer side of the fixed cylinder 11, and a threaded ring 15 is threadedly connected to the surface of the external threads on the fixed cylinder 11. Rotating the threaded ring 15 on the outer surface of the fixed cylinder 11, the threaded ring 15 will drive the limit ring 14 to move outside the fixed cylinder 11. Anti-slip patterns 19 are provided on the side wall of the threaded ring 15. The anti-slip patterns 19 on the threaded ring 15 increase the friction between the hand and the outer side of the threaded ring 15. Two guide blocks 20 are fixedly connected to the inner side of the limit ring 14, guide grooves 18 are opened on the side wall of the fixed cylinder 11, and the guide blocks 20 and the inner wall of the guide grooves 18 are slidably connected. The guide blocks 20 on the inner side of the limit ring 14 slide inside the guide grooves 18, which plays a role in restricting the moving direction of the limit ring 14.

[0030] Specifically, several connecting pins 16 are fixedly connected to the end side of the threaded ring 15, and balls 17 are clamped inside the connecting pins 16. During the rotation of the threaded ring 15, the balls 17 of the connecting pins 16 will roll on the end side of the limiting ring 14, reducing the frictional force during the relative movement between the threaded ring 15 and the limiting ring 14.

[0031] Working principle: Silicone also has good electrical insulation, light and aging resistance, mildew prevention, chemical stability, etc. Due to these excellent properties, silicone rubber plays an important role in modern medicine. The longest indwelling time of the silicone catheter is 29 days, while that of the ordinary catheter is 1 day. This can avoid multiple catheterizations, reduce the pain of patients and the occurrence of urinary tract cross-infection. After inserting the catheter 8 into the inner side of the urethra of an older patient, rotate the threaded ring 15 on the outer surface of the fixed cylinder 11. The anti-slip lines 19 on the threaded ring 15 increase the frictional force between the hand and the outer side of the threaded ring 15, facilitating the twisting of the threaded ring 15. The threaded ring 15 will drive the limiting ring 14 to move on the outer side of the fixed cylinder 11. The guiding block 20 inside the limiting ring 14 slides inside the guiding groove 18, playing a role in restricting the moving direction of the limiting ring 14. At this time, the distance between the limiting ring 14 and the fixed ring 12 will shorten, and multiple resilient wires 13 will be compressed and arched. At this time, the silicone sleeve 10 will bulge and support on the inner side of the urethra, thereby improving the stability of the catheter 8 during use after being inserted into the urethra. Rotating the threaded ring 15 in the reverse direction can reset the resilient wires 13. During the rotation of the threaded ring 15, the balls 17 of the connecting pins 16 will roll on the end side of the limiting ring 14, reducing the frictional force during the relative movement between the threaded ring 15 and the limiting ring 14, facilitating the twisting of the threaded ring 15. By setting the above structure, it is convenient to expand the position of the end of the catheter 8 according to the skin relaxation degree of the patient, avoiding the phenomenon of the catheter 8 shaking at the patient's urethra position and improving the stability of the catheter 8 during the urinary catheterization process at the patient's urethra position.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
