2. The catheter and the vaginal irrigation tube share three branch pipes of a water injection tube, an irrigation tube and a liquid outlet tube, and the three-way valve switching passage is rotated through the color identification handle to realize one-key switching of bladder and vaginal irrigation. Compared with the traditional separate operation of catheter and vaginal irrigation, the device has the advantages that only one-time posture fixation and one set of instrument are needed to complete double operation, and the nursing time of a single patient is shortened. The repeated exposure of the vagina and the urethra is avoided, the psychological pressure of the patient is reduced, and the urethral catheterization failure rate caused by urethral sphincter cramp of the aged patient is especially reduced. Two sets of independent instruments are not needed, disposable consumables such as a vaginal speculum, a urethral catheterization bag and the like are reduced for use through multiplexing of the branch pipes, and meanwhile disinfection time and space are saved. More deserves to emphasize, we hospital in the postload treatment room, and the patient still needs to be lithotomy position and exposes and open the vagina with the vaginal speculum and carry out the treatment, and after this technique utilized above-mentioned integral device, just can let the patient unify and accomplish catheter and vaginal irrigation in postload treatment room, postload treatment itself just needs the patient to be lithotomy position, consequently the patient can only need expose once, also only need use once vaginal speculum, has saved nursing time greatly, has also promoted patient experience.
3. The liquid outlet channel of the urinary tube and the vaginal liquid outlet channel are provided with the one-way valves, and the principle of one-way fluid conduction (such as a silica gel valve and a gravity type check structure) is utilized to ensure that urine and flushing liquid can only flow outwards. The one-way valve can prevent the urinary bladder urine from cross-polluting the vaginal flushing fluid, and can effectively prevent the backflow even if the pressure of the urinary bladder fluctuates or the body position changes.
4. The annular air bags at the end of the catheter head and the annular air bags at the end of the vaginal douche head share a water injection pipe, physiological saline is controlled and switched by a three-way valve, and the two air bags are respectively attached to the bladder neck and the inner wall of the vaginal orifice to form physical seal. Specifically, the catheter is fixed through the air bag, and is matched with outward light pulling to confirm tightness, so that the pipeline displacement caused by body position change is completely avoided, the vaginal air bag is attached to the vaginal orifice after being inflated, flushing liquid leakage is greatly reduced, and the environment of a treatment room is protected from being cleaned.
5. The vaginal irrigation tube is manually inserted, the situation that the insertion length is error is inevitably caused is avoided, the prior art solves the problems that a chuck is arranged near the head end of the vaginal irrigation tube (5 cm away from the tube head and is suitable for the length of an adult female vagina), excessive insertion caused by the difference of cervical length is avoided through physical limiting of the chuck, the operation fault tolerance rate is greatly improved even if a novice operation is performed, and particularly the focus of a patient is protected from being stabbed by the tube head of the vaginal irrigation tube.
6. Besides being integrally adhered to the fixed position of the vaginal irrigation tube, the chuck of the technology has another unique detachable design, can be clamped on the vaginal irrigation tube after being broken off into a C shape, is matched with the scale marks of the tube wall, and can adjust the insertion depth as required by a user, thereby being more suitable for the multi-scene condition of a hospital. In addition, the inner wall of the chuck is provided with a spherical bulge anti-slip structure and is matched with an inclined support which is arranged in a staggered manner with the spherical bulge, so that after the chuck is propped against one side of a human body, even if the vaginal irrigation tube is continuously moved inwards, the chuck can be further tightly held on the vaginal irrigation tube, slipping cannot occur, the fit between the chuck and the vaginal irrigation tube is stronger, and excessive insertion caused by cervical length difference can be avoided.
7. The technology also provides a technical scheme that the catheter is a shape memory polymer catheter, and the shape memory polymer catheter keeps a hard straight line shape at a low temperature (such as a refrigerating state), and is convenient for medical staff to accurately insert after being taken out when the catheter is used. After the urinary bladder is inserted into the urethra, the urinary bladder can quickly recover to a preset bent shape, is attached to the physiological curvature of the urethra, reduces the insertion resistance, reduces the risk of mucous membrane injury, shortens the operation time and improves the nursing efficiency. In addition, the technology provides a customized feasible route, the urethra size and the physiological structure of different patients are different, and the universal catheter can cause discomfort. The shape memory polymer can customize a special catheter according to CT or ultrasonic data of a patient through a 3D printing technology, parameters such as the pipe diameter, the bending angle, the air sac position and the like of the special catheter are accurately matched with individual requirements, the catheter is hard and slightly tough when inserted, the operation is convenient, the catheter becomes soft and is attached to the urethra after being inserted, and wearing comfort is remarkably improved.
8. Most of the traditional catheters are made of non-degradable materials, and medical waste treatment needs high-temperature incineration or chemical disinfection, so that pollution is easy to generate. When the degradable shape memory polymer catheter is processed in the follow-up process, the degradable shape memory polymer catheter can be triggered to degrade rapidly through specific conditions (such as specific temperature, humidity or enzyme solution), so that the medical waste treatment process is simplified, the solid waste amount is reduced, and the degradable shape memory polymer catheter meets the development trend of green medical treatment.
In the consumable management link of a large-scale hospital, the recovery supervision of the traditional catheter needs to be put into a large amount of manpower for checking. The shape memory polymer catheter greatly simplifies the management flow by virtue of the characteristic of taking out, namely counting down. For example, a special refrigerated storage area is arranged at a nursing station, and a nurse needs to operate immediately after taking the nursing station due to the characteristics of the special refrigerated storage area, so that the condition that the nursing station is confused after being placed aside after the nursing station is taken out conventionally is reduced. The design not only reduces the management cost, but also reduces the potential pollution caused by too many instrument circulation links, and remarkably improves the prevention and control efficiency of the hospital infection.
