Description

Technical Field

[0001] This utility model relates to a catheter, specifically a bladder pressure monitoring balloon catheter, belonging to the field of medical device technology. Background Technology

[0002] Most bladder pressure monitoring balloon catheters consist of a catheter body and a pressure monitoring module. The catheter body is a hollow tube with openings at both ends. The hollow interior serves as the urinary catheterization chamber, with the inlet at the top and the outlet at the bottom. A flow-stopping component is located near the bottom of the catheter body. The pressure monitoring module is located above the flow-stopping component and has a hollow interior to accommodate the pressure monitoring component. This hollow interior serves as the pressure monitoring chamber. One end of the pressure monitoring module is connected to the catheter body, and the pressure monitoring chamber communicates with the urinary catheterization chamber. The other end has a pressure monitoring opening that is closed to the outside. At least one pressure-transmitting catheter is connected to the pressure monitoring module and is located between the pressure monitoring module and the catheter body. The entire device is a hollow tube with openings at both ends. The pressure in the bladder is transmitted to the pressure monitoring chamber of the pressure monitoring module through the pressure-transmitting catheter, thereby detecting the bladder pressure during urination, determining the safe bladder pressure, and forming a personalized urination control and urination mechanism.

[0003] Currently, most existing bladder manometry balloon catheters are fixed by inflating an external balloon. However, relying solely on the external balloon to compress the bladder can cause the catheter to slide inwards during use. This sliding can alter the balloon's position, causing friction and pressure on the bladder mucosa, leading to bladder mucosal damage, bleeding, pain, and other discomfort. It may also increase the risk of bladder infection. Furthermore, catheter sliding can result in inaccurate pressure readings, affecting the doctor's assessment of the patient's bladder function and potentially leading to incorrect diagnoses and treatment plans. Therefore, we offer a bladder manometry balloon catheter to address these issues. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a bladder manometry balloon catheter, the specific technical solution of which is as follows:

[0005] A bladder pressure monitoring balloon catheter includes a catheter body, a first combined tube, and a second combined tube. A positioning ring is movably disposed on the outer side of the catheter body. Two sets of extension plates are disposed on the outer side of the positioning ring. Protrusions are disposed on the outer side of the extension plates. The positioning ring, extension plates, and protrusions are all made of rubber. A second balloon body is disposed at one end of the positioning ring, and the second balloon body is circularly sleeved on the outer side of the catheter body. A connecting tube is disposed through the interior of the second balloon body.

[0006] Preferably, the catheter body has a urinary catheterization channel inside, and a through hole No. 1 is provided inside the catheter body, and the through hole No. 1 communicates with the urinary catheterization channel.

[0007] Preferably, the first combined pipe is disposed on one side of the conduit body, and a water conveying channel is provided inside the first combined pipe and the conduit body. A second through hole is provided through the inside of the conduit body, and the second through hole communicates with the inside of the water conveying channel.

[0008] Preferably, the second combined pipe is located on the other side of the conduit body, and both the second combined pipe and the conduit body have gas delivery channels inside. The outer side of the conduit body is provided with a first airbag body, which is connected to the gas delivery channel.

[0009] Preferably, the urinary catheterization channel, water delivery channel, and air delivery channel inside the catheter body are adjacent but not interconnected.

[0010] Preferably, a positioning block is provided at the bottom end of the positioning ring, the connecting tube passes through the interior of the positioning block, and the positioning block is made of rubber.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, by setting up components such as a positioning ring and a second balloon body, the inner diameter of the positioning ring can be changed by pulling the two sets of rubber extension plates on the outer side of the positioning ring. This allows the positioning ring to move on the outside of the catheter body, making it easy to adjust the position of the second balloon body on the outside of the catheter body according to usage needs. The positioning ring can be used to position the second balloon body on the outside of the catheter body after adjustment. When the connecting tube is inflated by the external inflation component, the second balloon body can be inflated and expanded, blocking and limiting the position of the urethral opening, effectively preventing the catheter from sliding into the urethra and effectively reducing the risk of bladder infection.

[0013] 2. In this utility model, by setting components such as protrusions and positioning blocks, the rubber protrusions on the outer side of the extension plate are used to increase the friction between the worker's fingers and the extension plate. The connecting tube passes through the rubber positioning block, and the positioning block can support and limit the extended connecting tube. Attached Figure Description

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A bladder pressure monitoring balloon catheter;

[0022] The device includes a catheter body 1, a first combined tube 4, and a second combined tube 7. A positioning ring 10 is movably disposed on the outer side of the catheter body 1. Two sets of extension plates 11 are disposed on the outer side of the positioning ring 10. A protrusion 12 is disposed on the outer side of the extension plate 11. The positioning ring 10, extension plates 11, and protrusion 12 are all made of rubber. A second airbag body 13 is disposed at one end of the positioning ring 10. The second airbag body 13 is circularly sleeved on the outer side of the catheter body 1. A connecting tube 14 is disposed through the interior of the second airbag body 13. A positioning block 15 is disposed at the bottom end of the positioning ring 10. The connecting tube 14 passes through the interior of the positioning block 15. The positioning block 15 is made of rubber.

[0023] The positioning ring 10 is made of elastic rubber. The inner diameter of the positioning ring 10 is smaller than the outer diameter of the catheter body 1. By pulling the two sets of rubber extension plates 11 on the outer side of the positioning ring 10, the positioning ring 10 can be stretched, allowing it to move on the outer side of the catheter body 1. This allows the second airbag body 13 to move on the outer side of the catheter body 1, facilitating adjustment of its position on the outer side of the catheter body 1 according to usage requirements. The positioning ring 10 can be used to position the adjusted second airbag body 13 on the outer side of the catheter body 1. The rubber protrusions 12 on the outer side of the extension plates 11... To increase the friction between the staff's fingers and the extension plate 11, since the connecting tube 14 is connected to the inside of the second airbag body 13, when the connecting tube 14 is inflated by the external inflation component, the second airbag body 13 can be inflated and expanded, blocking and limiting the position of the urethral opening, effectively preventing the catheter from sliding into the urethra, and effectively reducing the risk of bladder infection. The inflation port of the connecting tube 14 is sealed using existing technology, such as using a rubber ring. The connecting tube 14 passes through the rubber positioning block 15, and the positioning block 15 can support and limit the extended connecting tube 14.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A bladder pressure monitoring balloon catheter;

[0025] The catheter body 1 has a urinary channel 2 inside. A first through hole 3 is provided through the inside of the catheter body 1 and is connected to the urinary channel 2. A first combination tube 4 is located on one side of the catheter body 1. A water delivery channel 5 is provided inside the first combination tube 4 and the catheter body 1. A second through hole 6 is provided through the inside of the catheter body 1 and is connected to the water delivery channel 5. A second combination tube 7 is located on the other side of the catheter body 1. A gas delivery channel 8 is provided inside both the second combination tube 7 and the catheter body 1. A first balloon body 9 is provided on the outside of the catheter body 1 and is connected to the gas delivery channel 8. The urinary channel 2, water delivery channel 5 and gas delivery channel 8 inside the catheter body 1 are adjacent but not connected.

[0026] The catheter body 1 is one of the main components of the bladder pressure monitoring balloon catheter. After the catheter body 1 is inserted into the bladder, the No. 1 balloon body 9 on the outside of the catheter body 1 can be inflated to fix the position of the catheter body 1 in the bladder or sense changes in bladder pressure. The pressure in the bladder is transmitted to the pressure measuring chamber through the pressure transmitting catheter, causing changes in the gas pressure in the pressure measuring chamber. The pressure sensor then converts the pressure signal into an electrical signal or other form of output, thereby realizing the measurement of bladder pressure. It communicates with the inside of the urinary channel 2 through the No. 1 through-hole 3, allowing urine in the patient's bladder to enter the urinary channel 2 through the No. 1 through-hole 3. The urine flows out through the other end of the urinary catheter channel 2. After the urine collection bag is connected to the inside of one end of the catheter body 1, the urine inside the urinary catheter channel 2 can be injected into the urine collection bag. By pumping water into the water delivery channel 5 inside the first combination tube 4, the water in the water delivery channel 5 can be injected into the patient's bladder through the second through hole 6. The water in the patient's bladder enters the urinary catheter channel 2 through the first through hole 3 and flows out, which has the effect of foam flushing. After inflating the air delivery channel 8 inside the second combination tube 7 using the external inflation component, the first balloon body 9 can be inflated in the patient's bladder, and the catheter body 1 can be initially positioned.
