Description

Technical fields:

[0001] This utility model relates to the field of post-urological care technology, and in particular to an anti-squeezing frame for male patients after urological surgery. Background technology:

[0002] Male patients often require catheterization after urological surgery. Catheterization involves inserting a catheter through the urethra into the bladder to drain urine, relieving urinary retention and allowing for the collection of uncontaminated urine samples for examination. However, existing catheters are prone to slow flow or blockage after insertion due to pressure from patient movements such as turning over, causing inconvenience. Furthermore, the simple support structure cannot be adjusted to accommodate different urethral opening sizes. Utility model content:

[0003] The purpose of this invention is to provide a post-operative anti-compression frame for male urological patients, addressing the shortcomings of existing technologies. Through the coordination of the catheter, balloon 2, arc-shaped frame, pressure sensor, and solenoid valve, balloon 2 is inserted into the urethra along with the catheter. The arc-shaped frame secures the balloon 2 at the glans penis, keeping it positioned at the urethral opening. Once the catheter tip is inserted into the bladder and ready for catheterization, the user can connect the suction tube to an external needle, injecting gas to inflate balloon 2 and support the urethral opening. Meanwhile, the air pressure sensor monitors the air pressure at the second airbag in real time. Once the preset air pressure is reached, the solenoid valve can be closed via the signal line connected to the signal line hole, ensuring that there is no over- or under-inflation. The presence of the second airbag also ensures that if the patient squeezes the second airbag while turning over, the pressure on the catheter will be reduced due to the gas pressure. This effectively avoids the inconvenience caused by the catheter slowing down or becoming blocked after being squeezed by the patient's movements after insertion. Furthermore, the simple support structure cannot adjust the support size according to the different sizes of the patient's urethral opening.

[0004] This utility model is implemented by the following technical solution: a postoperative anti-compression frame for male patients after urological surgery, including a urinary catheter and urinary inlets. The outer wall of the end of the urinary catheter is processed with multiple urinary inlets. An airbag II is slidably connected to the upper part of the outer wall of the urinary catheter. The inner wall of the airbag II is coated with a titanium dioxide coating. Multiple arc-shaped frames are fixedly connected at equal intervals to the lower part of the outer wall of the airbag II. A thin tube is fixedly connected to one side of the lower end of the airbag II.

[0005] A pressure sensor and a solenoid valve are sequentially installed at the lower end of the thin tube.

[0006] Signal wire holes are machined on the upper end of the pressure sensor and on both sides of the solenoid valve.

[0007] A one-way valve is installed on the upper inner wall of the catheter.

[0008] An airbag is installed on the outer wall of the catheter, below the one-way valve.

[0009] The adjacent arc-shaped frames are distributed at an angle of 1 degree.

[0010] Advantages of this utility model:

[0011] This invention utilizes the coordination of a urinary catheter, a balloon pressure sensor, and a solenoid valve. Gas is injected through the needle to inflate the balloon, supporting the patient's urinary inlet. The pressure sensor continuously monitors the pressure at the balloon. Once the preset pressure is reached, the solenoid valve closes via a connected signal line. The presence of the balloon reduces pressure on the catheter, effectively preventing slow flow or blockage caused by patient movement after insertion, thus avoiding inconvenience. Furthermore, the simple support structure cannot adjust the support size according to the patient's urethral opening size. Attached image description:

[0020] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] according to Figure 1-6 A postoperative anti-compression frame for male urological patients includes a urinary catheter 1 and urinary inlets 2. The outer wall of the distal end of the urinary catheter 1 is machined with multiple urinary inlets 2. An air balloon 4 is slidably connected to the upper part of the outer wall of the urinary catheter 1. The inner wall of the air balloon 4 is coated with a titanium dioxide coating 10. The titanium dioxide coating 10 can harden the inner wall of the air balloon 4, that is, when the air balloon 4 is inflated, it will only expand outward and will not expand inward to compress the urinary catheter 1. In addition, the titanium dioxide coating 10 can effectively ensure the smoothness and sterility of the inner wall. Multiple arc-shaped frames 5 are fixedly attached at equal intervals to the lower part of the outer wall of the air balloon 4. The arc-shaped frames 5 are used to block the specific position of the air balloon 4 so that it is locked at the urethral opening. A thin tube 8 is fixedly connected to one side of the lower end of the air balloon 4.

[0022] A pressure sensor 7 and a solenoid valve 6 are sequentially installed at the lower end of the thin tube 8. The specific models of the pressure sensor 7 and the solenoid valve 6 can be determined according to requirements. Signal wire holes 11 are machined on the upper end of the pressure sensor 7 and on both sides of the solenoid valve 6. The signal wire hole 11 on one side of the solenoid valve 6 is used to connect to the pressure sensor 7 to receive the signal from the pressure sensor 7. The signal wire hole on the other side of the solenoid valve 6 is used to receive a separate opening signal for venting air when the second airbag 4 retracts. A one-way valve 9 is installed on the upper inner wall of the catheter 1. The first airbag 3 is installed on the outer wall of the catheter 1 below the one-way valve 9. The adjacent arc-shaped frames 5 are distributed at a 60-degree angle. The catheter 1 is connected to a flexible tube for inflating or deflating the first airbag 3. This structure is existing technology and is therefore not shown in the figure. It can be a small flexible tube with a valve. When inflating, the valve is opened and air is injected into the first airbag 3 through the needle. When deflating, the valve is opened and air is drawn out through the needle.

[0023] Working principle:

[0024] When this anti-compression frame is needed after urological surgery in male patients, firstly, insert the inner wall of the second balloon 4 with the arc-shaped frame 5 from above the catheter 1 (at this time, neither the first balloon 3 nor the second balloon 4 is inflated). Figure 1 The illustration shows the balloon 3 in its uninflated state and the balloon 4 in its inflated state (this is for demonstration purposes only; the actual usage should be based on the instruction manual). Next, apply a lubricant such as Vaseline to the outer walls of catheter 1 and balloon 4. After even application, insert catheter 1 into the male patient's urethra from the top, guiding it along the urethra to the bladder. After inserting a certain distance into the bladder, connect it to the air inflation tube at the other end of catheter 1 (catheter 1 has a flexible tube inside for inflating or deflating balloon 3; this is existing technology and therefore not shown in the illustration). Specifically, air can be injected into balloon 3 by connecting an external needle to this air inflation tube, causing balloon 3 to inflate and become larger. This allows balloon 3 to be positioned securely in the urethra connected to the bladder, preventing the catheter from being pulled out due to movement. After completion, connect catheter 1 to the urine bag. When there is urine in the bladder, it will flow through the catheter port 2 of catheter 1 and eventually into the urine bag.

[0025] During the insertion of catheter 1 into the urethra, the lubricated and uninflated balloon 4 is also inserted into the urethra. The arc-shaped frame 5 holds the balloon 4 at the glans penis, restricting its position and ensuring it remains positioned at the urethral opening. Once the end of catheter 1 is inserted into the bladder and ready for catheterization, the user can connect the suction tube 8 to an external needle, injecting gas to inflate the balloon 4 and support the catheterization opening. Simultaneously, the pressure sensor 7 monitors the pressure at the balloon 4 in real time. Once the preset pressure is reached (ensuring the catheter 1 remains undeformed and does not cause pain), the signal line connected to signal line hole 11 controls the solenoid valve 6 to close, preventing further needle insertion. Even pushing the head cannot inject more gas. Since the size of the urethral opening varies from person to person, this case uses a combination of a pressure sensor 7 and a solenoid valve 6. This ensures that the air pressure inside the second balloon 4 only changes after it expands to fit the urethral opening. The air pressure change automatically controls the flow of injected gas, preventing over- or under-injection. The presence of the second balloon 4 also ensures that if the patient squeezes the second balloon 4 while turning over, the pressure on the catheter 1 will be reduced due to the gas pressure. This effectively avoids the inconvenience caused by the catheter 1 being squeezed by the patient's movements after insertion, resulting in slow flow or blockage. Furthermore, the simple support structure cannot adjust the support size according to the different sizes of the patient's urethral opening.

[0026] Note: In actual use, the inner wall of the second balloon 4 is coated with a titanium dioxide coating 10. The titanium dioxide coating 10 can harden the inner wall of the second balloon 4, that is, when the second balloon 4 is inflated, it will only expand outward and will not expand inward to squeeze the catheter 1. In addition, the titanium dioxide coating 10 can effectively ensure the smoothness and sterility of the inner wall. After the catheterization is completed, the user can extract the gas from the first balloon 3 and the second balloon 4 to make them retract, then remove the catheter 1, and finally remove the second balloon 4 from the outer wall of the catheter 1 for disinfection for the next use.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
