Description

Technical Field

[0001] This application relates to the technical field of urinary catheters, and in particular to a urine bag-free urinary catheter. Background Technology

[0002] In the medical field, urinary catheterization is a common and important treatment for patients who have difficulty urinating due to illness, surgery, or other reasons. Catheters help patients drain urine smoothly and maintain the normal function of the urinary system.

[0003] Traditional urinary catheters are typically a single, integrated structure, with the drainage tube not detachable from the main body, and the lower end permanently connected to a urine bag. This causes considerable inconvenience to patients' daily lives. Patients must carry the urine bag at all times, regardless of their activity level. This not only increases the physical burden but also severely restricts their freedom of movement, forcing them to be extremely careful during walking, sitting, and lying down, fearing that the urine bag might be squeezed or bumped, affecting urine drainage or even causing leakage. Utility Model Content

[0004] To facilitate easy and flexible wearing and disassembly, this application provides a urine bag-free catheter.

[0005] The present application provides a urine-free bag-free catheter with the following technical solution: A urine-free catheter includes an insertion catheter, the head of which is sealed with a catheter plug, and the lower end of which is fitted with a drainage tube. The drainage tube is detachably connected to the insertion catheter. The insertion catheter includes an internal soft part and a connecting sleeve. The connecting sleeve is installed at the lower end of the internal soft part and is sealed and fixedly connected to the internal soft part. A limiting seat is integrally formed on the outer surface of the connecting sleeve. Several sets of auxiliary support members are obliquely installed on the outer surface of the limiting seat in a circumferential direction. The lower ends of the auxiliary support members are fixedly connected to the limiting seat.

[0006] By adopting the above technical solution, the head of the urinary catheter is sealed with a catheter plug, facilitating stable insertion into the bladder through the urethra. Simultaneously, the detachable external drainage tube ensures quick removal when not in use, effectively increasing the patient's flexibility in daily life. Furthermore, the detachable connection between the urinary catheter and the external drainage tube provides convenient maintenance and replacement. By designing the urinary catheter with a structure that integrates the internal soft part and the connecting sleeve, the internal soft part is stably inserted into the patient's body during use, while the connecting sleeve remains externally, facilitating the installation and removal of the external drainage tube. The inclusion of a limiting seat and an auxiliary support for tilted installation on the connecting sleeve makes wearing the connecting sleeve more stable and comfortable, while also providing stable support for smooth urine drainage and the catheter's movement within the body during urination.

[0007] Optionally, the catheter plug includes a central tube and a limiting airbag. The head of the central tube has several sets of drainage grooves, and the limiting airbag is sleeved and fixed on the outer side of the central tube.

[0008] By adopting the above technical solution, the urinary catheter connector includes a central tube and a limiting balloon. The drainage groove design on the central tube can effectively collect urine and guide it to the drainage channel. The cooperation between the limiting balloon and the central tube indicates that the balloon can be used to position and fix the urinary catheter in the body, adjusting its tightness at the bladder neck by inflating or deflating it, thereby achieving a firm fixation and preventing displacement.

[0009] Optionally, an air supply top pipe connected to the limiting airbag is provided on the outer side of the soft part inside the body, and an air supply middle pipe connected to the air supply top pipe is installed on the outer side of the connecting sleeve.

[0010] By adopting the above technical solution, the air supply top tube in the soft part of the body is connected to the limiting airbag, and the air supply middle tube on the connecting sleeve is connected to the air supply top tube, forming a channel for supplying air to the limiting airbag. This design allows the limiting airbag to be inflated and deflated externally, thereby realizing the fixation and removal of the urinary catheter.

[0011] Optionally, an air supply bottom pipe is provided on the outer side of the drainage outer pipe, and an insert air pipe connected to the air supply middle pipe is fixedly installed at the head of the air supply bottom pipe, and an air injection port is sealed at the lower end of the air supply bottom pipe.

[0012] By adopting the above technical solution, the bottom gas supply pipe on the outer drainage pipe is connected to the middle gas supply pipe via an insert gas pipe, and is equipped with an injection port. This indicates that the entire gas supply channel is connected, and the injection port is located at the end of the outer drainage pipe, making it convenient for external operators to inflate and deflate the gas using syringes or other equipment.

[0013] Optionally, the head of the drainage tube is fixedly installed with an insertion fluid tube connected to the connecting sleeve, and the head of the drainage tube is fixedly installed with an elastic clamping plate. The outer side of the connecting sleeve is provided with a mating groove shell for installing the elastic clamping plate.

[0014] By adopting the above technical solution, the head of the drainage tube is equipped with an insertion fluid tube for connection with the connecting sleeve, ensuring smooth urine flow. More importantly, the elastic retaining plate at the head of the drainage tube and the mating retaining groove on the connecting sleeve provide a robust and easy-to-disassemble connection, ensuring a stable connection between the drainage tube and the insertion catheter, and facilitating separation.

[0015] Optionally, the limiting seat includes a seat housing and an elastic valve for controlling the on / off of the air supply pipe. The elastic valve is installed at the lower end of the seat housing, and a first suspension line is fixedly installed at the lower end of the seat housing. A cover that blocks the lower end of the connecting sleeve is connected to the lower end of the first suspension line.

[0016] By adopting the above technical solution, the limiting seat includes a seat housing and an elastic valve that controls the opening and closing of the air supply pipe. The elastic valve allows for the opening and closing of the air supply pipe, thereby better controlling the inflation and deflation of the limiting airbag. When inflation or deflation is required, the elastic valve is pressed to open the air supply channel; when not in use, the air supply channel is closed. A suspension wire at the lower end of the seat housing is connected to a cap, which is used to cover the lower end of the connecting sleeve, ensuring that the lower end of the connecting sleeve can be sealed after the drainage outer tube is disassembled, thus preventing foreign objects from entering.

[0017] Optionally, a second suspension line is fixedly installed at the lower end of the base shell, and an insert plate for controlling the on / off state of the connecting sleeve is connected to the lower end of the second suspension line. A pull-out groove for installing the insert plate is provided on the base shell.

[0018] By adopting the above technical solution, the insert plate connected to the second suspension line at the lower end of the seat shell, and the pull-out groove on the seat shell, indicate that the opening and closing of the connecting sleeve can be controlled by pulling the insert plate externally. Thus, during normal urination, pulling the insert plate opens it, facilitating the control of the opening and closing of the connecting sleeve channel.

[0019] Optionally, the auxiliary support includes a diagonal brace and a flexible ball, with the lower end of the diagonal brace fixedly mounted on the base plate housing and the flexible ball fixedly mounted on the head of the diagonal brace.

[0020] By adopting the above technical solution, the diagonal brace is fixed to the seat shell, and the flexible ball is installed at the head of the diagonal brace. The inclined auxiliary support structure can play a role in distributing pressure, providing support and guidance during the patient's wearing process, helping the connecting sleeve to be placed more stably on the outside of the patient's body. At the same time, the design of the flexible ball can also reduce friction and damage to the surface skin.

[0021] In summary, this application includes at least one of the following beneficial technical effects: By designing a detachable drainage tube, this application ensures that the drainage tube and the urine bag at its lower end can be removed when not in use, reducing the inconvenience for patients carrying the urine bag and improving their freedom of movement. Simultaneously, this catheter exhibits good stability in terms of fixation and drainage, effectively preventing catheter displacement and leakage, and reducing the risk of infection. Furthermore, the inclusion of auxiliary support components also improves patient comfort when wearing the catheter. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a urine bag-free catheter. (Refer to...) Figure 1 , Figure 2 and Figure 3A urine bag-free catheter includes an insertion catheter 1, with a catheter plug 2 sealed to the head of the insertion catheter 1. A drainage tube 3 is also installed at the lower end of the insertion catheter 1. The drainage tube 3 is detachably connected to the insertion catheter 1. The insertion catheter 1 includes an internal soft part 11 and a connecting sleeve 12. The connecting sleeve 12 is installed at the lower end of the internal soft part 11 and is sealed and fixedly connected to the internal soft part 11. A limiting seat 4 is integrally formed on the outer surface of the connecting sleeve 12. Several sets of auxiliary support members 5 are installed obliquely along the circumferential direction on the outer surface of the limiting seat 4, and the lower ends of the auxiliary support members 5 are fixedly connected to the limiting seat 4. The catheter plug 2, sealed to the head of the insertion catheter 1, allows for stable insertion into the bladder through the urethra. The detachable drainage tube 3 ensures quick disassembly when not in use, effectively increasing the flexibility of the patient's daily life. The detachable connection between the insertion catheter 1 and the drainage tube 3 also provides convenient maintenance and replacement. By designing the urinary catheter 1 with a structure in which the internal soft part 11 and the connecting sleeve 12 cooperate, the internal soft part 11 can be stably inserted into the patient's body during use, while the connecting sleeve 12 is left outside the body to facilitate the installation and removal of the drainage tube 3. Furthermore, by setting a limiting seat 4 and an inclined auxiliary support 5 on the connecting sleeve 12, the wearing of the connecting sleeve 12 is made more stable and comfortable, while providing smooth drainage of urine and stable support for the urinary catheter inside the body during urination.

[0030] Reference Figure 1 The urinary catheter connector 2 includes a central tube 21 and a limiting balloon 22. The head of the central tube 21 has several sets of drainage grooves 211. The limiting balloon 22 is fitted and fixed to the outer surface of the central tube 21. The drainage grooves 211 on the central tube 21 are designed to effectively collect urine and guide it to the drainage channel. The cooperation between the limiting balloon 22 and the central tube 21 indicates that the balloon may be used to position and fix the urinary catheter in the body. Inflation or deflation adjusts its tightness at the bladder neck, thereby achieving a secure fixation and preventing displacement. An air supply top tube 111 connected to the limiting balloon 22 is provided on the outer surface of the soft inner part 11, and an air supply middle tube 121 connected to the air supply top tube 111 is installed on the outer surface of the connecting sleeve 12. The air supply tube 111 of the soft part 11 is connected to the limiting airbag 22, and the air supply tube 121 on the connecting sleeve 12 is connected to the air supply tube 111, forming a channel for supplying air to the limiting airbag 22. This design allows the limiting airbag 22 to be inflated and deflated externally, thereby achieving the fixation and removal of the urinary catheter.

[0031] Reference Figure 4 and Figure 5An air supply bottom pipe 31 is provided on the outer surface of the drainage outer pipe 3. An insert air pipe 311, connected to the air supply middle pipe 121, is fixedly installed at the head of the air supply bottom pipe 31, and an air injection port 312 is sealed at the lower end of the air supply bottom pipe 31. The air supply bottom pipe 31 on the drainage outer pipe 3 is connected to the air supply middle pipe 121 via the insert air pipe 311 and has an air injection port 312. This indicates that the entire air supply channel is connected, and the air injection port 312 is located at the end of the drainage outer pipe 3, facilitating inflation and deflation by external operators using syringes or other equipment. An insert liquid pipe 313, connected to the connecting sleeve 12, is fixedly installed at the head of the drainage outer pipe 3, and an elastic clamping plate 32 is fixedly installed at the head of the drainage outer pipe 3. A mating groove shell 122 for installing the elastic clamping plate 32 is provided on the outer surface of the connecting sleeve 12. The head of the drainage tube 3 is equipped with an insertion tube 313 for connecting to the connecting sleeve 12 to ensure smooth urine flow. More importantly, the elastic retaining plate 32 at the head of the drainage tube 3 and the mating retaining groove shell 122 on the connecting sleeve 12 provide a secure and easy-to-disassemble connection, ensuring a stable connection between the drainage tube 3 and the insertion catheter 1, and facilitating separation.

[0032] Reference Figure 2 and Figure 3 The limiting seat 4 includes a seat housing 41 and an elastic valve 42 that controls the opening and closing of the air supply pipe 121. The elastic valve 42 is installed at the lower end of the seat housing 41, and a first suspension line 411 is fixedly installed at the lower end of the seat housing 41. The lower end of the first suspension line 411 is connected to a cover 412 that blocks the lower end of the connecting sleeve 12. The limiting seat 4 includes a seat housing 41 and an elastic valve 42 that controls the opening and closing of the air supply pipe 121. The elastic valve 42 allows for the opening and closing of the air supply pipe 121, thereby better controlling the inflation and deflation of the limiting airbag 22. When inflation or deflation is needed, pressing the elastic valve 42 opens the air supply channel, and closing the air supply channel when not in use. The suspension line at the lower end of the seat housing 41 is connected to the cover 412, which blocks the lower end of the connecting sleeve 12, ensuring that the lower end of the connecting sleeve 12 can be sealed after the drainage outer pipe 3 is disassembled, thus preventing foreign objects from entering. A second suspension wire 413 is fixedly installed at the lower end of the seat shell 41. The lower end of the second suspension wire 413 is connected to an insert plate 414 for controlling the opening and closing of the connecting sleeve 12. The seat shell 41 has a pull-out groove 415 for installing the insert plate 414. The insert plate 414 connected to the second suspension wire 413 at the lower end of the seat shell 41, and the pull-out groove 415 on the seat shell 41, indicate that the opening and closing of the connecting sleeve 12 can be controlled by pulling the insert plate 414 externally. In this way, during normal urination, it can be pulled out (only the connecting sleeve 12 needs to be connected vertically, without pulling the insert plate 414 off the seat shell 41 to avoid urine overflowing from the pull-out groove 415), making it convenient to control the opening and closing of the connecting sleeve 12 channel through the insert plate 414.

[0033] Reference Figure 3 The auxiliary support component 5 includes a diagonal brace 51 and a flexible ball 52. The lower end of the diagonal brace 51 is fixedly mounted on the seat shell 41, and the flexible ball 52 is fixedly mounted on the head of the diagonal brace 51. The structure of the diagonal brace 5, with its inclined installation, ensures that it distributes pressure, provides support, and guides the patient during passage, helping the connecting sleeve 12 to be placed more stably outside the patient's body. Simultaneously, the design of the flexible ball 52 may reduce friction and damage to the surface skin.

[0034] The implementation principle of the urine bag-free catheter in this embodiment is as follows: In actual operation, the insertion catheter, catheter plug, and drainage tube are assembled, and a urine bag is connected to the lower end of the drainage tube assembly. Then, the catheter can be inserted. The limiting balloon 22 is deflated to its minimum volume, and the catheter is then inserted into the bladder through the urethra. When the catheter reaches the predetermined depth, the limiting balloon 22 is inflated through the inflation port 312. By installing a syringe on the inflation port, the gas from the syringe enters the limiting balloon 22 through the bottom air supply tube 31, the insertion air tube 311, the middle air supply tube 121, and the top air supply tube 111, causing it to inflate and thus fixing the catheter to the bladder neck to prevent it from slipping out. Pulling out the insertion plate 414 ensures that urine in the bladder enters the central tube 21 from the drainage groove 211, then enters the insertion catheter 1, and finally flows into the urine bag through the drainage tube 3.

[0035] When not in use, push the insert plate 414 to the innermost position, and then the connecting sleeve 12 can be cut off through the insert plate 414. Then the drainage tube 3 and urine bag can be removed, so that the urine catheter 1 and urine catheter plug 2 can be worn on the body. Finally, the cap 412 is fastened to the bottom of the connecting sleeve 12.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
