Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a graduated urinary catheter. Background Technology

[0002] Hypospadias is a congenital urethral developmental abnormality in males, characterized by the urethral opening not being in the normal position of the glans penis, but located on the ventral side of the penis, scrotum, or perineum. In severe cases, there may be multiple openings (multiple urethral opening malformation). The key to surgical repair of hypospadias is to measure the distance of the urethral defect and ensure the accuracy of the anastomosis position in order to avoid postoperative complications.

[0003] Multiple urethral openings are a complex type of hypospadias, characterized by multiple openings or bifurcations in the urethra. During surgery, medical staff need to determine the distance between each urethral opening to adjust the insertion depth and support distribution of the catheter, thereby better repairing the urethral openings. However, existing catheters lack calibrated markings, forcing medical staff to rely on experience and visual estimation to determine the insertion depth, which often makes it difficult to guarantee accuracy in practice.

[0004] Therefore, existing technologies still need improvement. Utility Model Content

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Hypospadias is a congenital urethral abnormality in males, characterized by the urethral opening not being located in the normal position of the glans penis, but rather on the ventral side of the penis, scrotum, or perineum. This condition not only affects the patient's appearance but can also severely impact urinary function and reproductive health. In severe cases, hypospadias may be accompanied by multiple openings, known as polyspadias, which further complicates treatment. The key to surgical repair of hypospadias lies in accurately measuring the distance of the urethral defect and ensuring precise anastomosis to avoid postoperative complications such as urethral stricture and urinary fistula.

[0022] Multiple urethral openings are the most complex type of hypospadias, characterized by multiple openings or bifurcations in the urethra. This malformation not only increases the difficulty of surgery but also places higher demands on postoperative functional recovery. During surgery, medical staff need to accurately measure the distance between each urethral opening to adjust the insertion depth and support distribution of the catheter, thereby better repairing the urethral openings. However, existing catheters lack calibrated markings, forcing medical staff to rely on experience and visual inspection to determine the insertion depth, which often makes it difficult to guarantee accuracy in practice, increasing the risks and uncertainties of the surgery.

[0023] To address the shortcomings of the prior art, this utility model discloses a graduated urinary catheter, such as... Figure 1 As shown, it includes: a drainage catheter 100 and a connecting catheter 200; the drainage catheter 100 is used to insert into the urethra to drain urine; the drainage catheter 100 is provided with a drainage hole 110 and a scale mark 120 along its length, the scale mark 120 being used to measure the distance between adjacent urethral openings; the connecting catheter 200 is connected to the drainage catheter 100; the connecting catheter 200 is used to connect to a urine bag.

[0024] In use, one end of the connecting catheter 200 is connected to the urine bag, and the other end is connected to the drainage catheter 100. The drainage catheter 100 is inserted into the urethra from one urethral opening. The drainage catheter 100 guides the urine in the urethra into the connecting catheter 200, and then into the urine bag for storage. At the same time, the drainage catheter 100 is equipped with a scale mark 120. When the drainage catheter 100 advances in the urethra, the scale mark 120 measures the distance between adjacent urethral openings, providing accurate data support for subsequent repairs by medical staff.

[0025] Specifically, the graduated catheter disclosed in this embodiment can be used in urethral surgery for multiple urethral openings. Multiple urethral openings are a complex type of hypospadias, characterized by the presence of multiple openings in the urethra. During surgery, medical staff select one urethral opening, insert the drainage catheter 100 through that opening, and slowly push the drainage catheter 100 into the urethra. When the end of the drainage catheter 100 moves to the next opening in the urethra, the doctor reads the graduation mark 120 to obtain the insertion depth of the drainage catheter 100, which represents the distance between the two urethral openings.

[0026] In this embodiment, as Figure 2 As shown, the end of the drainage catheter 100 is provided with multiple drainage holes 110, which are arranged alternately on both sides of the drainage catheter 100. When medical staff insert the drainage catheter 100 into the urethra, urine flows into the drainage catheter 100 through the drainage holes 110 and then into the urine bag through the connecting catheter 200, thereby achieving simultaneous drainage and measurement of the distance between urethral openings. Simultaneously, the alternating arrangement of the multiple drainage holes 110 allows for more even pressure distribution on the drainage catheter 100 in the urethra, reducing pressure on local urethral tissues and lowering the risk of tissue damage.

[0027] In another embodiment of this utility model, the drainage conduit 100 has a circular cross-sectional shape; the end of the connecting conduit 200 connected to the drainage conduit 100 is hemispherical, and the other end of the connecting conduit 200 away from the drainage conduit 100 is cylindrical. With the connecting conduit 200 and the drainage conduit 100 connected at a hemispherical end, when the urine bag is connected to the connecting conduit 200, the urine bag's connection port is first fitted onto the end of the connecting conduit 200 away from the drainage conduit 100, and then gradually extends to the hemispherical end. Thus, the middle part of the urine bag's connection port fits onto the cylindrical shape, providing effective support. Simultaneously, the end of the urine bag's connection port fits onto the hemispherical shape, and the hemispherical structure acts as a closing mechanism for the end of the urine bag's connection port, preventing the urine bag from falling off.

[0028] In this embodiment, the connecting conduit 200 is provided with a plurality of protrusions 210; the plurality of protrusions 210 are arranged alternately on the outer side wall of the connecting conduit 200. The protrusions 210 can increase the friction between the connecting conduit 200 and the urine bag, preventing the urine bag from falling off. In one embodiment, the connecting conduit 200 is also provided with a fastening strap; when the urine bag is fitted onto the connecting conduit 200, the fastening strap is wrapped around the end of the urine bag that connects to the connecting conduit 200 to ensure the stability of the urine bag.

[0029] In this embodiment, the drainage catheter 100 is circular in cross-sectional shape to match the shape of the urethra. The natural cross-sectional shape of the human urethra is close to a circle. A circular catheter can better fit the inner wall of the urethra and also makes it easier for the drainage catheter to pass through the bends and narrow parts of the urethra during insertion, reducing the difficulty of insertion and patient discomfort.

[0030] In this embodiment, both the connecting catheter 200 and the drainage catheter 100 include any one of silicone catheters, rubber catheters, and latex catheters; the thickness of the connecting catheter 200 is greater than the thickness of the drainage catheter 100. When the thickness of the connecting catheter 200 is greater than the thickness of the drainage catheter 100, the overall rigidity of the connecting catheter 200 is greater than that of the drainage catheter 100. The drainage catheter 100 is soft and easier to insert into the urethra, while the connecting catheter 200 is rigid and more securely connected to the urine bag, preventing the urine bag from loosening and falling off after a long period of connection. In one embodiment, the diameter of the drainage catheter 100 is 2-3 mm, and the diameter of the connecting catheter 200 is greater than 3 mm. The diameter of the connecting catheter 200 is larger than that of the drainage catheter 100. The larger diameter can reduce the risk of urine reflux, especially when the urine bag is in a high position or the patient moves. Urine is less likely to flow back from the urine bag into the urinary catheter or bladder, reducing the risk of infection. At the same time, the connecting catheter 200 is matched with the connection port of the urine bag and is designed with a large diameter to facilitate quick and secure connection, reducing the risk of urine leakage or dislodgement.

[0031] In another embodiment of this utility model, the scale mark 120 is a scale line; the endpoint of the scale line is flush with the end of the drainage catheter 100. The length of the scale line is 5-20 cm. The endpoint of the scale line is aligned with the end of the drainage catheter 100, meaning the zero point of the scale line is the endpoint of the drainage catheter 100. This ensures that after the drainage catheter 100 is inserted into the urethra, the scale value recorded by medical personnel at each urethral opening represents the distance from the insertion position to that urethral opening, improving the efficiency of data recording.

[0032] In actual use, the length of the scale line is 10 cm, and the length of the drainage catheter 100 is also 10 cm. The 10 cm scale line can intuitively show the insertion limit of the drainage catheter 100, avoiding the drainage catheter 100 being inserted too deeply and stimulating the bladder trigone, reducing the risk of bladder spasm or hematuria. At the same time, the urethra of children is usually 4-6 cm, and the 10 cm drainage catheter 100 can ensure sufficient drainage of urine, reducing the risk of urine retention and infection.

[0033] In another embodiment of the present invention, the graduated catheter further includes a guidewire; one end of the guidewire is inserted into the drainage catheter 100 and abuts against the end of the drainage catheter 100 opposite to the connecting catheter 200, and the other end extends out of the opening.

[0034] Specifically, the drainage catheter 100 is closed at the end opposite to the connecting catheter 200. In actual use, medical staff first insert one end of the guidewire into the drainage catheter 100 and abut it against the end of the drainage catheter 100, while the other end extends out of the connecting catheter 200. Then, the urine bag is connected to the connecting catheter 200. Subsequently, the drainage catheter 100 is inserted into the urethra. The guidewire can increase the support of the drainage catheter 100, making it less likely to bend or fold during insertion, ensuring that the drainage catheter 100 can be inserted into the urethral opening. At the same time, it ensures that the end of the drainage catheter 100 can be accurately aligned with the urethral opening. The distance between the urethral opening and the insertion position of the drainage catheter 100 is measured, improving the accuracy of the measurement and providing accurate data support for subsequent repair by medical staff, reducing reliance on visual inspection or experience judgment by medical staff.

[0035] In summary, this utility model discloses a graduated urinary catheter, comprising: a connecting catheter; a drainage catheter for insertion into the urethra to drain urine; the drainage catheter having a drainage hole and graduated markings along its length, the graduated markings being used to measure the distance between adjacent urethral openings; a connecting catheter connected to the drainage catheter; and the connecting catheter for connecting to a urine bag. This application sets graduated markings on the drainage catheter, allowing medical personnel to accurately measure the distance between each urethral opening, providing accurate data support for subsequent repair and solving the problem of inaccurate measurements caused by reliance on visual inspection or experience in traditional surgery.
