Problems solved by technology

[0008] 3. Use fingers, tweezers, and hemostats to hold the catheter in the air and apply force. Because the catheter is flexible and travels in a tortuous way, the direction of the applied force is difficult to be the same as the centerline of the urethra. The direction of travel and the direction of force are at a certain angle. The force parallel to the centerline of the urethra is only a component of the applied force, so a greater force can insert the catheter, and the urethra is more damaged

Embodiment 1

[0058] Embodiment 1: existing clinical common urinary catheter such as figure 1 As shown, it is a hollow main pipeline composed of solid materials with an inner surface 11 and an outer surface 12. It is usually sterilized before use. The hollow pipeline is the catheter lumen 10, including the head 13 that enters the bladder 0 during use. , the tail 14 left outside the body and the middle part 15 connecting the head 13 and the tail 14, the head 13 is provided with a urine inlet 130, and the tail 14 is provided with a urine outlet 140; a bladder fixed bladder 132 for indwelling catheterization Located under the urine inlet 130 of the catheter head 13, a certain amount of gas and or liquid is injected into the one-way valve 2 at the opening 1322 of the filling side branch 142 of the bladder fixed bladder, through the passage in the catheter wall 1321 enters and fills the fixed bladder 132 of the bladder so that it stays in the bladder cavity 00 and is not easy to come out.

Embodiment 2

[0067] Embodiment 2: as Figure 14 , 15 , 16, on the guide protection part 7 of the present invention, the finger holding part that protrudes from its outer surface is set as two finger rings 723, and the finger is placed in the hollow of the finger ring 723 to operate more stably and reliably; further, especially for the convenience of single Hand-operated, also provided with the main body socketed with the cylindrical main body 71 of the guide protection part 7. The head 811 that is socketed with the shape main body 71, the arc-shaped head 811 of the driving part 8 is completely placed in the cylindrical hollow 70 of the guide protection part, and the two are slidably matched; in order to ensure that the urinary catheter 1 advances in the guide protection part 7 In order to obtain reliable and accurate guidance, an annular protruding guide part 715 with an inner diameter slightly larger than the outer diameter of the catheter and a length L1 is provided inside the opening 7...

Embodiment 3

[0072] Embodiment 3: as Figure 17 As shown, the difference from Embodiment 2 is that there are two continuous finger rings 823 at the tail of the driving part 8. This design obviously prolongs the distance of finger control. When the patient's urethra is long, the stroke of the thumb inserted into one finger ring 823 ends. When the insertion of the urinary catheter 1 has not been completed, it can be switched to another finger ring 823 in time to continue advancing.

Abstract

The invention discloses a urethral catheter applicable to women. The urethral catheter comprises a hollow body pipeline made from a solid material provided with an inner surface and an outer surface and also comprises a guiding protective part which can make at least the portions, located in the urinary bladder and the urethra, of the urethral catheter during indwelling arranged in the part in a sleeved mode in use and a urethral catheter driving part in sleeved connection with a cylindrical body of the guiding protective part and provided with a rod-like body, wherein the body of the urethral catheter is a cylindrical. The shortcoming of traditional 'guide-free suspended indwelling' is eliminated in the safety mode of 'guided approaching and indwelling', the contamination of surrounding tissue of the external urethral orifice to the urethral catheter is thoroughly avoided, and the urethral inner membrane damage caused by urethrostenosis in the indwelling process can be avoided to the most degree.

Description

technical field [0001] The invention relates to a urinary catheter, in particular to a urinary catheter suitable for women, and belongs to the technical field of medical devices. Background technique [0002] Urinary catheter is the most common clinical medical device. After being inserted into the human body through the urethra, it can drain urine from the bladder to the outside of the body; it can be taken out after one urine drainage, or it can be left in place for multiple drainages for a long time. [0003] However, the operation and indwelling of the catheter will lead to different degrees of lower urinary tract injury, and the injury of the lower urinary tract is more likely to cause or aggravate lower urinary tract infection, which will further affect the function of the lower urinary tract or even the organs of the whole body. [0004] The female urethra is shorter and thicker than that of men, with a length of only about 4 cm. The structure around the external open...
