[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 and Figure 2 As shown in FIGS. and, an embodiment provided by the present utility model: a novel medical catheter includes a catheter 1, an airbag 2 is arranged on the left side of the catheter 1, a connecting tube 3 is fixedly connected to the rear side of the airbag 2, a water injection tube 4 is fixedly connected to the front side of the connecting tube 3, a plug 5 is arranged on the front side of the water injection tube 4, a sleeve 6 is arranged on the outer side of the catheter 1, a plurality of drainage holes 7 are opened on both the upper and lower sides of the sleeve 6, a limit groove 8 is opened on the front side of the sleeve 6 and on the right side of the drainage hole 7, a fixed block 9 is slidably connected inside the limit groove 8, the rear side of the fixed block 9 is fixedly connected to the front side of the catheter 1, rubber clamping blocks 10 are arranged on both the left and right sides inside the limit groove 8, and a drainage component is arranged inside the sleeve 6.
[0031] Specifically, the design of the airbag 2 on the left side of the catheter 1 enables the catheter to be stably fixed in the bladder, preventing it from falling off or shifting, thereby ensuring the continuity and stability of urine drainage. The arrangement of the connecting tube 3 and the water injection tube 4 enables medical staff to conveniently inject physiological saline or gas into the airbag 2 to make it expand and fix. The plug 5 is convenient for medical staff to operate and can effectively prevent liquid leakage, keeping the operation environment clean. The sleeve 6 is used to prevent damage to the urethra when replacing the catheter again, further improving the comfort of the patient. With the cooperation of the rubber clamping blocks 10, the fixed block 9 and the limit groove 8, additional stability can be provided when the catheter 1 is fixed, preventing it from moving or rotating.
[0032] Refer to Figure 1 and Figure 3 As shown in FIGS. and, the drainage component includes a water-absorbing foam dressing 11, and the water-absorbing foam dressing 11 is arranged inside the sleeve 6 and the drainage hole 7.
[0033] Specifically, a plurality of drainage holes 7 are provided on the sleeve 6. These drainage holes 7 not only allow urine to flow out smoothly but also prevent blood and other possible secretions from overflowing from the inside of the sleeve when the urinary catheter 1 is replaced, thereby reducing the risk of contamination and infection. With the cooperation of the absorbent foam dressing 11, it can quickly and effectively absorb the blood and urine flowing in through the drainage holes 7, ensuring that the inside of the sleeve 6 always remains dry and clean. This not only improves the comfort of the patient but also further reduces the risk of infection.
[0034] Refer to Figure 1 - Figure 3 , an indicating scale is provided on the front side of the sleeve 6, a hard valve 12 is provided on the rear side of the connecting pipe 3, a one-way valve 13 is provided on the right side of the urinary catheter 1. The absorbent foam dressing 11 is made of polyester film. The connecting pipe 3 is connected to the urinary catheter 1, and the water injection pipe 4 is connected to the urinary catheter 1. The drainage holes 7 are evenly distributed on the upper and lower sides of the sleeve 6.
[0035] Specifically, the indicating scale provided on the front side of the sleeve 6 provides great convenience for medical staff. By observing the scale, medical staff can accurately judge the depth of the urinary catheter in the body, thus ensuring that the urinary catheter 1 is placed in the appropriate position. This not only improves the accuracy of the operation but also reduces the risks caused by improper placement of the urinary catheter 1. The one-way valve 13 on the right side of the urinary catheter 1 ensures the one-way flow of urine and prevents the possibility of urine backflow and contamination. The absorbent foam dressing 11 is made of polyester film. Polyester film has good water absorption and breathability, can quickly absorb and drain liquid, and at the same time keep the inside of the sleeve 6 dry and comfortable. This material also has certain antibacterial properties, which helps to reduce the risk of infection. The connection between the water injection pipe 4 and the urinary catheter 1 facilitates medical staff to inject liquid into the balloon.
[0036] Working principle: When it is necessary to install the catheter 1 for a patient, first insert the end with the balloon 2 and the sleeve 6 into the bladder together. To prevent the catheter 1 from falling off, at this time, it is necessary to open the plug 5 on the front side of the water injection pipe 4, inject normal saline into the water injection pipe 4 through a syringe needle, and transport it to the inside of the balloon 2 through the water injection pipe 4 to complete the fixation. When there is a problem of urethral blockage and the catheter 1 needs to be replaced in time, open the plug 5 at this time to drain the saline in the balloon 2. After draining, rotate the catheter 1 until the fixing block 9 on the catheter 1 passes through between the two rubber blocks 10. At this time, the catheter 1 can be slowly withdrawn from the inside of the sleeve 6. When replacing the new catheter 1, insert the catheter 1 slowly into the patient's bladder along the sleeve 6, and rotate the other end of the catheter 1 to slide along the limit groove 8 on the sleeve 6 until the fixing block on the catheter 1 passes through the two rubber blocks 10 and is limited by the two rubber blocks 10. At this time, it is necessary to open the plug 5 on the front side of the water injection pipe 4, inject normal saline into the water injection pipe 4 through a syringe needle, and transport it to the inside of the balloon 2 through the water injection pipe 4 to complete the replacement. When replacing the catheter 1, in order to prevent blood and urine from flowing out of the sleeve 6, corresponding drainage holes 7 are provided on the sleeve 6. Absorbent foam dressings 11 are provided inside both the sleeve 6 and the drainage holes 7. Blood and urine can flow into the drainage holes 7 and be adsorbed by the absorbent foam dressings 11 inside the sleeve 6 and the drainage holes 7, avoiding the accumulation of blood and urine in the sleeve and reducing the risk of contamination.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
