Description

Technical Field

[0001] The invention relates to the technical field of urinary catheterization devices, in particular to a urinary catheterization device for pediatric surgery. Background Art

[0002] The use of a urinary catheter is a common and critical step in pediatric surgery. However, due to the particularity of the pediatric urethral structure, the selection and application of urinary catheters face many challenges. The pediatric urethra is relatively narrow, which requires the use of a smaller diameter catheter to ensure smooth insertion and reduce damage to the urethra. However, smaller diameter catheters have obvious deficiencies in catheterization efficiency, especially when large amounts of urine need to be discharged quickly, and their catheterization speed may not meet clinical needs.

[0003] In addition, although the design of the three-channel catheter provides more functions in some cases (such as simultaneous catheterization, flushing, and drug infusion), the diameter of each channel is further reduced, increasing the risk of blockage. Blockage will not only affect the catheterization effect, but may also cause urine retention, increasing the risk of infection and other complications. At the same time, the thinner diameter catheter is significantly less resistant to bending. The bending of the catheter in the body will not only completely block the urine flow, but may also cause mechanical damage to the urethral wall, further aggravating the child's pain and difficulty of recovery.

[0004] Therefore, a novel urinary catheter is urgently needed to solve the defects of the prior art. Summary of the invention

[0005] The object of the present invention is to provide a urinary catheterization device for pediatric surgery to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1 to 8 An anti-bending guide wire 12 is embedded in the inner wall of the catheter 1, a liquid inlet 9 is provided at the head of the catheter 1, and a liquid outlet pipe joint 3 is provided at the tail of the catheter 1, which is connected to the liquid inlet 9. The diameter of the catheter 1 is suitable for the size of the urethra of children, ensuring smooth insertion and reducing damage to the urethra.

[0030] The urine guiding device 16 includes a urine volume metering bucket 18 and a negative pressure pump 17, which are arranged on a base 20. The urine volume metering bucket 18 is used to place a transparent urine collecting bag 14, and the port of the transparent urine collecting bag 14 is connected to the liquid outlet pipe joint 3 through a connecting pipe 13, and one end of the connecting pipe 13 away from the liquid outlet pipe joint 3 extends out of the bottom of the transparent urine collecting bag 14. The port of the transparent urine collecting bag 14 is also connected to a negative pressure pipe 15, and one end of the negative pressure pipe 15 away from the port of the transparent urine collecting bag 14 is connected to the air inlet of the negative pressure pump 17.

[0031] When the present embodiment is working, the urinary catheter 1 is inserted into the urethra of the child through the liquid inlet 9 at the head, and urine enters the interior of the urinary catheter 1 through the liquid inlet 9 and is discharged through the liquid outlet pipe joint 3 at the tail. The urine guiding device 16 is connected to the liquid outlet pipe joint 3 through the connecting pipe 13, and the negative pressure pump 17 generates negative pressure to extract urine from the urinary catheter 1 and collect it in the transparent urine collection bag 14. The anti-bending guide wire 12 is buried in the inner wall of the urinary catheter 1 to enhance the anti-bending ability of the urinary catheter and prevent the urinary catheter from bending in the body, resulting in urine flow blockage or urethral damage.

[0032] Example 2: Please refer to Figures 1-2 The urinary catheterization device for pediatric surgery is different from the embodiment 1 in that liquid level sensors 19 are provided at equal distances from bottom to top on the inner wall of the circumference of the urine volume metering bucket 18, a box body 21 is provided on the front side of the base 20, a controller is provided in the box body 21, and a touch screen 22 is provided on the top of the box body 21. The liquid level sensor 19 transmits a liquid level signal to the controller in a unidirectional manner, the controller transmits a control signal to the negative pressure pump 17, and the touch screen 22 transmits signals to the controller in a bidirectional manner.

[0033] The box body 21 is also provided with a buzzer, which sounds an alarm when the topmost liquid level sensor 19 detects liquid.

[0034] The working of this embodiment is that when urine enters the transparent urine collection bag 14 and reaches a certain liquid level, the liquid level sensor 19 transmits a signal to the controller. The controller calculates the urine extraction speed based on the liquid level signal, and then adjusts the working state of the negative pressure pump 17 to ensure that the urine is extracted at the set speed. The touch screen 22 displays information such as urine volume and negative pressure pump status, and allows medical staff to manually adjust parameters, such as urine extraction speed. When the urine reaches the highest liquid level, the buzzer sounds an alarm to remind medical staff to deal with it in time.

[0035] Example 3: Please refer to Figures 4 to 8, the urinary catheter device for pediatric surgery is different from the embodiment 1 in the structure of the three-channel urinary catheter. The urinary catheter 1 is a three-channel structure. The urinary catheter 1 is divided into three channels, inner and outer. The outermost channel is the airbag channel 5, the middle channel is the urinary catheter channel 6, and the innermost channel is the flushing channel 7. The airbag channel 5 connects the airbag 8 at the head and the airbag injection valve 4 at the tail, the urinary catheter channel 6 connects the liquid inlet 9 at the head and the liquid outlet pipe joint 3 at the tail, and the flushing channel 7 connects the flushing liquid outlet 10 at the head and the flushing drug injection port 2 at the tail. A wire tube 11 is provided on the inner wall of the flushing channel 7, and an anti-bending guide wire 12 is inserted inside the wire tube 11. The three channels of the urinary catheter 1 are used for urinary catheterization, flushing and drug infusion respectively. The urinary catheter channel 6 is used to discharge urine, the flushing channel 7 is used to flush the urethra or infuse drugs, and the airbag channel 5 is used to control the filling and discharge of the head airbag 8 and fix the position of the urinary catheter.

[0036] Example 4: Please refer to Figures 7-8 The urinary catheter device for pediatric surgery is different from the embodiment 1 in that the anti-bending guide wire 12 is made of alloy material, and the diameter of the anti-bending guide wire 12 is 0.05-0.015 mm. The anti-bending guide wire 12 can be detachably placed in the wire tube 11, and the anti-bending guide wire 12 can be sterilized and reused.

[0037] In this embodiment, the anti-bending guide wire 12 is made of high-strength alloy material, and its diameter is controlled between 0.05-0.015 mm, which can provide sufficient support without increasing the overall diameter of the catheter. The anti-bending guide wire 12 is detachable for easy disinfection and reuse.

[0038] Example 5: Please refer to Figure 3 The urinary catheter device for pediatric surgery is different from that of Example 1 in that the urinary catheter 1, the connecting tube 13, the transparent urine collecting bag 14 and the negative pressure tube 15 are all disposable consumables, ensuring hygiene and safety each time they are used.
