[0030] The adjustable male urinary catheter fixing device proposed in this embodiment has many beneficial effects. First, the device has high flexibility and adaptability and can be adjusted according to the specific conditions of the patient. The user can accurately adjust the tightness of the cuff by rotating the adjustment knob 50 to adapt to penises of different sizes, thereby ensuring the stability of the adjustable male urinary catheter fixing device. This avoids the problem of knotting too tight or too loose when directly using a fresh-keeping bag, and reduces the risk of damage to the penis and urethra.

[0031] Secondly, the design of the device takes into account the special needs of patients with urinary incontinence. The adjustment knob 50 is used in conjunction with the first matching rack 31 and the second matching rack 41. The user can achieve fine-tuning by rotating the adjustment knob 50 to obtain the best fixing effect. The first cuff 30, the second cuff 40 and the arc-shaped belt 20 can be stably fixed on the male genitals, which helps to improve the safety of urination for patients. In addition, the device also takes into account the needs of long-term use. The adjustable male urinary catheter fixing device can be reused, thereby reducing medical costs.

[0032] Specifically, the adjustable male urinary catheter fixing device disclosed in this embodiment can be used to insert a fresh-keeping bag into the installation channel, and the opening of the fresh-keeping bag is folded out from the port of the installation channel, that is, the fresh-keeping bag is sleeved on the side of the shell 10 away from the first cuff 30, the second cuff 40 and the arc-shaped belt 20. In the process of tightening the first cuff 30, the second cuff 40 and the arc-shaped belt 20, the fresh-keeping bag will be squeezed and fixed at the same time, so that the accommodating cavity of the fresh-keeping bag is connected to the urethra and is not easy to fall off.

[0033] Specifically, the first mating rack 31 and the second mating rack 41 disclosed in this embodiment are both single-sided racks and are arranged opposite to each other, so that when the adjusting knob 50 is rotated, the first cuff 30 and the second cuff 40 can move toward each other or move away from each other.

[0034] Specifically, the number of teeth of the first mating rack 31 and the second mating rack 41 disclosed in this embodiment can be set according to needs. The more teeth there are in a limited space, the finer the adjustment precision can be. The more teeth there are for a fixed number of teeth, the wider the adjustable range can be. It can be set according to actual needs and will not be elaborated here.

[0035] Specifically, the width of the arc-shaped belt 20, the first hoop 30 and the second hoop 40 disclosed in this embodiment is 0.8 cm-1.2 cm. The product structure is relatively small and light, and can flexibly adapt to different needs.

[0036] Specifically, the shell disclosed in this embodiment is an elastic transparent shell that can shrink or expand as the first cuff and the second cuff are adjusted.

[0037] Specifically, the housing 10 disclosed in this embodiment is provided with a buzzer, and an electromagnetic flow sensor is provided on the inner wall of the housing 10. The electromagnetic flow sensor is connected to the buzzer through a wire. When urine passes through the sensor, an induced voltage is generated inside the sensor. This voltage is then captured by the electrodes on the sensor and converted into an electrical signal. After the electrical signal is sensed, an alarm can be sounded through the buzzer. In actual use, when a bedridden patient starts to urinate, the electromagnetic flow sensor senses the passage of liquid and the buzzer sounds to remind the caregiver to observe the urination situation.

[0038] like Figure 2 and Figure 3As shown, as another implementation of the present embodiment, a positioning gear ring 12 is circumferentially arranged on the side wall of the mounting hole 11, and the adjusting knob 50 can rotate around the axis of the positioning gear ring 12. The adjusting knob 50 includes a stop body 51 and an engaging portion 511 arranged on the stop body 51, and the engaging portion 511 is arranged in the radial direction of the stop body 51. The engaging portion 511 is engaged with the positioning gear ring 12 to provide a blocking force, so that the positioning of the first strap 30 and the second strap 40 is more reliable, and the loosening of the first strap 30 and the second strap 40 can be limited.

[0039] Specifically, the stop body 51 disclosed in this embodiment is provided with a plurality of grooves for reducing the material usage on the product, which can significantly reduce the weight of the product and reduce the production cost, so that the adjustable male catheterization fixation device is lighter when worn on the reproductive organ of a male patient and will not cause a burden to the patient.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, as another implementation of this embodiment, the adjustment knob 50 also includes a detachably connected rotating cover 53 and a gear 54, and the two sides of the gear 54 are respectively engaged with the first cuff 30 and the second cuff 40, so that the user can accurately adjust the tightness of the first cuff 30 and the second cuff 40 to meet different needs.

[0041] Specifically, the rotating cover 53, the gear 54 and the stop body 51 disclosed in this embodiment are all coaxially arranged, and the gear 54 is fixedly connected to the stop body 51. The fixed connection design can improve the stability and reliability of the adjustable male catheterization fixing device. When the rotating cover 53 rotates around the axis of the positioning gear ring 12, it can drive the gear 54 and the stop body 51 to rotate.

[0042] Specifically, the stop body 51 disclosed in this embodiment is disposed between the rotating cover 53 and the gear 54 , so that the stop body 51 can achieve the stop function without occupying the space of the installation channel.

[0043] Specifically, as another implementation of this embodiment, an extrusion block 531 is provided on the side of the rotating cover 53 facing the gear 54, wherein the meshing portion 511 includes a support arm 5111 and a pawl 5112, one end of the support arm 5111 is connected to the stop body 51, and the other end is connected to the pawl 5112, the support arm 5111 can undergo elastic deformation, and a protrusion is provided on the side of the support arm 5111 facing the positioning gear ring 12, and an extrusion surface is provided on the protrusion. When the rotating cover 53 rotates, the extrusion block 531 abuts against the extrusion surface, that is, the extrusion block 531 squeezes the elastic arm toward the center point of the stop body 51, so that the pawl 5112 on the end is disengaged from the meshing state with the positioning gear ring 12, and the blocking force is released, so that the rotating cover 53 can rotate smoothly regardless of whether it is forward or reverse.

[0044] like Figure 4 and Figure 5 As shown, as another implementation of this embodiment, a transmission block 512 is further provided on the outer peripheral wall of the stop body 51. When the rotating cover 53 rotates, the extrusion block 531 abuts against the transmission block 512 to drive the stop body 51 to rotate, so that when the user rotates the rotating cover 53, the driving of the gear 54 and the stop body 51 is more timely and efficient, avoiding slipping during transmission.

[0045] Specifically, the meshing parts 511 disclosed in this embodiment are provided with two pairs of symmetrical arrangements, two meshing parts 511 in a pair are arranged opposite to each other, four extrusion blocks 531 are provided, two transmission blocks 512 are provided, a pair of meshing parts 511 and a transmission block 512 are alternately arranged, that is, arranged in a cross shape, and an extrusion block 531 is provided between a pair of meshing parts 511 and a transmission block 512. The transmission of the entire structure is stable and the force is more balanced.

[0046] Specifically, when one of the extrusion blocks 531 disclosed in this embodiment abuts against the extrusion surface, the other extrusion block 531 abuts against the transmission block 512, which can effectively protect the pawl 5112 and prevent the extrusion block 531 from excessively extruding the protrusion and causing the support arm 5111 to break.

[0047] Specifically, as another implementation of this embodiment, a support arm 5111 is disclosed that is extended in an arc shape, which is more convenient for elastic deformation when subjected to extrusion force, and is concentrically arranged with the positioning gear ring 12, so that when the support arm 5111 is squeezed by the extrusion block 531, it is deformed along the radial direction of the positioning gear ring 12, and the pawl 5112 is separated from the positioning gear ring 12 more accurately and reliably.

[0048] Specifically, as another implementation of this embodiment, the outer diameter of the housing 10 gradually increases in the direction away from the adjusting knob 50, and the outer diameter of the housing 10 is provided with an annular protrusion 13 at the maximum position, and the adjustable male urinary catheter fixing device further comprises a clamping ring 60 slidably provided on the outer peripheral wall of the housing 10, and the clamping ring 60 can slide in the direction toward the annular protrusion 13 and squeeze the annular protrusion 13. Since the fresh-keeping bag will overlap when folded at the penis, it is not completely transparent, which makes it inconvenient for medical staff to observe the fastening condition, such as whether the penis is swollen. Therefore, the housing 10 portion corresponding to the arc belt 20 can be used for medical staff to observe, and the fresh-keeping bag passes through the clamping ring 60, and the clamping ring 60 slides downward and abuts tightly against the annular protrusion 13, squeezing the opening of the fresh-keeping bag, so that the opening of the fresh-keeping bag is connected with the installation channel, fixing the position of the fresh-keeping bag, and preventing the fresh-keeping bag from falling off.

[0049] Specifically, the clamping ring 60 disclosed in this embodiment is arranged between the knob assembly and the annular protrusion 13. The clamping ring 60 is sleeved on the outer wall of the shell 10. When sliding in a direction away from the annular protrusion 13, it will abut against the knob assembly, and when sliding in a direction away from the rotating assembly, it will abut against the annular protrusion 13. The clamping ring 60 will not detach from the shell 10, which is convenient for medical staff to use.

[0050] Specifically, the clamping ring 60 disclosed in this embodiment is an elastic clamping ring having a certain elasticity. When the clamping ring 60 slides and squeezes in the direction toward the annular protrusion 13, a certain elastic deformation is generated. The force of the elastic deformation is toward the center of the circle, sealing the gap between the shell 10 and the fresh-keeping bag, thereby further preventing urine leakage.

[0051] Specifically, the elastic compression ring disclosed in this embodiment is a rubber ring or a silicone ring. This embodiment only exemplifies an elastic compression ring, but the protection scope of the utility model is not limited thereto. Other types of elastic seals can achieve the technical effects disclosed in this application and, as equivalent replacements of the concept of the utility model, should also be within the protection scope of this application.

[0052] Specifically, as another implementation of this embodiment, the gear 54 is a polyetheretherketone gear 54, and there is no need to set a hardware gear 54, so that the adjustable male catheterization fixing device is lighter, easier to wear, does not cause a burden, and has lower friction loss than the metal gear 54, which means that they are quieter during operation. And / or the housing 10 is a medical silicone rubber transparent housing, and the arc belt 20 is a medical silicone rubber transparent arc belt, so that medical staff can directly observe the compression of the penis, and if a mark is found, the tightness can be adjusted in time, and it can be reused after cleaning and disinfection after use.

[0053] Specifically, as another implementation of this embodiment, the first cuff 30, the second cuff 40 and the arc-shaped belt 20 are all provided with an antibacterial coating on the side away from the housing 10, which effectively prevents bacteria from growing and multiplying. The antibacterial coating helps to reduce oxidation, corrosion and damage, thereby reducing the risk of infection. This helps to keep the adjustable male urinary catheterization fixture clean and hygienic, and reduces the probability of infection.

[0054] In summary, the present application discloses an adjustable male urinary catheter fixing device, which has many beneficial effects. First, the device has a high degree of flexibility and adaptability, and can be adjusted according to the specific conditions of the patient. The user can accurately adjust the tightness of the cuff by rotating the adjustment knob 50 to adapt to penises of different sizes, thereby ensuring the stability of the adjustable male urinary catheter fixing device. This avoids the problem of knotting too tight or too loose that may occur when directly using a fresh-keeping bag, and reduces the risk of damage to the penis and urethra.

[0055] Secondly, the design of the device takes into account the special needs of patients with urinary incontinence. The adjustment knob 50 is used in conjunction with the first matching rack 31 and the second matching rack 41. The user can achieve fine-tuning by rotating the adjustment knob 50 to obtain the best fixing effect. The first cuff 30, the second cuff 40 and the arc-shaped belt 20 can be stably fixed on the male genitals, which helps to improve the safety of urination for patients. In addition, the device also takes into account the needs of long-term use. The adjustable male urinary catheter fixing device can be reused, thereby reducing medical costs.
