Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, more particularly, the present application relates to a transfusion type catheter device. BACKGROUND

[0002] Different spinal cord injury sites, injury degrees and ranges show different types of bladder and urethral dysfunction, so spinal cord injury patients need to insert a catheter for catheterization. The International Continence Society (ICS) recommends intermittent catheterization as the preferred method for treating neurogenic bladder dysfunction. The currently widely used intermittent catheterization is based on a drinking plan, and the catheterization frequency is changed according to the residual urine volume. Literature reports that through a 5-year follow-up study, it was found that as high as 50% of patients gave up intermittent catheterization after discharge. Due to the shortcomings of regular catheterization, many scholars propose "on-demand" catheterization based on safe capacity. During the catheterization process, a bladder scanner is used for guidance, when the patient's urine volume is less than 1 / 3 of the safe capacity, scanning every 2 hours, when the urine volume is 1 / 3 to 2 / 3 of the safe capacity, scanning every 1 hour, and when the urine volume reaches the safe capacity, intermittent catheterization is given and the catheterization time, urine volume and scanning urine volume are recorded to determine the timing of catheterization. Daurat's study suggests that bladder capacity scanning guided intermittent catheterization can reduce 78% unnecessary catheterization times and reduce urinary tract infections. Fedorkow's study suggests that bladder capacity scanning guided intermittent catheterization can reduce patient discomfort, reduce nursing workload and reduce medical costs. Whether it is intermittent catheterization by time or intermittent catheterization on demand, 40cmH2O is considered as the upper limit of safe pressure, and the corresponding bladder capacity is considered as safe capacity.

[0039] Exemplary leakage prevention module

[0040] The connection between the lower end of the catheter tube 14 and the urine bag 15 in the prior art is mostly achieved by the structure of mutual insertion between tubes. However, the urine bag is replaced many times a day, while the catheter tube body 1 does not need to be replaced every day, so the connecting part of the lower end of the catheter tube 14 is stretched many times, which makes the connection not firm every time, so that the connecting part of the lower end of the catheter tube 14 is loose, which may cause urine leakage. Moreover, as the weight of the urine bag 15 increases with the increase of urine, the urine bag 15 may fall from the lower end of the catheter tube 14. Therefore, in some embodiments of the present application, the lower end of the catheter tube 14 is connected to the urine bag 15 through a leakage-proof module 3. The leakage-proof module 3 not only can be connected firmly, but also will not cause urine leakage after connection.

[0041] In addition, the leakage-proof module 3 with the structure makes it unnecessary to worry about the loosening of the catheter tube 14 and the urine bag 15 during the transportation of the patient.

[0042] As shown in Figures 5-11 The leakage-proof module 3 with the structure includes a first docking cap 4 and a second docking cap 5. The first docking cap 4 is installed at the lower end of the catheter tube 14, and the second docking cap 5 is installed on the urine inlet tube 151 of the urine bag 15. The first docking cap 4 and the second docking cap 5 are connected to each other. The first docking cap 4 is provided with an inner docking pipe 41. Two first docking holes 411 are formed in the end of the inner docking pipe 41. A first outer opening 412 corresponding to the first docking hole 411 is formed on the outer wall of the inner docking pipe 41. A switch hole 413 corresponding to the first outer opening 412 is formed on the outer wall of the first docking cap 4. A first driving member is installed in the switch hole 413.

[0043] As shown in Figures 7-8 Correspondingly, the second docking cap 5 is provided with two first docking strips 51. When in use, the first docking strips 51 are aligned with the first docking holes 411. The second docking cap 5 is moved towards the first docking cap 4. The first docking strips 51 move in the first docking holes 411. The end of the first docking strips 51 is provided with an outer hook 511. The outer hook 511 can move into and extend into the first outer opening 412 to be clamped, so that the inner docking pipe 41 abuts against the second docking cap 5, the leakage-proof module 3 is turned on, and the first docking cap 4 and the second docking cap 5 are separated by pushing the outer hook 511 with the first driving member when the urine bag 15 needs to be replaced, so that the first docking strips 51 can be pulled out of the first docking holes 411, which facilitates the replacement of the urine bag 15 and prevents the urine bag 15 from falling from the lower end of the catheter tube 14.

[0044] Exemplary first driving member

[0045] As Figures 5-6 shown, further, some embodiments of the present application provide a specific structure of the first driving member described above, where the structure of the first driving member includes a driving rod 414 and a top spring 415, wherein the top spring 415 is installed on the driving rod 414, and the upper end of the top spring 415 is connected with the driving rod 414, and the lower end is connected with the inner end of the switch hole 413, so when the medical staff pushes the driving rod 414 towards the inside of the first docking cap 4, and then the lower end of the driving rod 414 pushes the outer protruding hook 511 from the first outer hole 412 into the first docking hole 411, and then the medical staff pulls out the first docking strip 51, so as to realize the separation of the first docking cap 4 and the second docking cap 5, which is convenient for the medical staff to use the structure to replace the urine bag 15.
