AI Technical Summary
The existing four-chamber urethra catheter is insufficient injected to cause uneven expansion, which is prone to unilateral expansion and urine leakage. The contact area between the balloon and the catheterization port is small, making it difficult to effectively prevent urine leakage.
The elastic force line is evenly fixed on the inner side of the balloon and the side wall of the catheter, and a conical sleeve is set at the front end of the catheter to expand evenly when the balloon is expanded. The conical sleeve is fitted with the inner wall of the catheter to increase the contact area. Improve the effect of urine leakage through double protection.
It achieves uniform expansion of the balloon and effective occlusion of the catheter port, significantly improves the effect of preventing urine and ensures the closure of urine.

Abstract
Description
Technical Field
[0001] The utility model relates to a four-lumen urinary catheter, in particular to an anti-urine leakage and air-filled four-lumen urinary catheter, belonging to the technical field of medical equipment. Background Art
[0002] In the prior art, for example, the utility model with application number 201820072773.4 discloses an improved four-chamber hemostatic air-bag urinary catheter. In order to solve the problem that when a patient bleeds due to urethral mucosal damage caused by coagulation disorders or long-term indwelling of a urinary catheter, there is no effective and feasible method of compression hemostasis due to the special structure of the urethra. An air bag is arranged on the catheter, and the interior of the air bag is inflated through a second air injection tube to compress the inner wall of the urethra, thereby stopping local bleeding in the urethra. The method is economical and practical.
[0003] Similar to the above application, there are still some shortcomings:
[0004] After the balloon is inserted into the bladder along with the catheter, if the amount of gas injected is small, the balloon may not expand evenly and may expand on one side. Therefore, a large amount of gas needs to be injected, which is inconvenient to control. In addition, after the balloon is inflated, the outer side is spherical, and the contact area with the urination opening is small, which is prone to urine leakage.
[0005] Therefore, a urine leakage-proof air-filled four-lumen urinary catheter is designed to optimize the above-mentioned problems. Utility Model Content
[0006] The main purpose of the utility model is to provide an inflatable four-lumen urinary catheter that prevents urine leakage. An elastic line is evenly fixed between the inner side of the balloon and the side wall of the catheter, and the elastic line is arranged along the circumference of the catheter, so that the balloon can be evenly expanded when it is inflated, ensuring that the catheter is located at the center of the balloon, and improving the shielding effect of the catheter port. A conical sleeve is fixed at the front end of the catheter, and the open end of the conical sleeve is connected and conducted with the balloon. After the balloon is inflated, the conical sleeve is also expanded to form a cone. When the catheter is fixed, the conical sleeve can be closely fitted with the inner wall of the catheter port, and the balloon is fitted at the front end of the catheter port, increasing the contact area with the catheter port, and improving the urine leakage prevention effect of the device in a double protection manner.

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.
[0023] like Figure 1-Figure 4 As shown, this embodiment provides a leakage-proof inflatable four-lumen urinary catheter, including a urinary catheter 1, side holes 2 are symmetrically opened on both sides of one end of the urinary catheter 1, a urination port 3 is provided at the other end of the urinary catheter 1, a drug administration tube 4 is provided on the outer side of one end of the urinary catheter 1 close to the urination port 3, a drug discharge port 5 communicated with the drug administration tube 4 is provided on the end of the urinary catheter 1 close to the side hole 2, a first inflatable tube 6 is provided on the outer side of one end of the urinary catheter 1 close to the urination port 3, and a hemostatic tube is provided on the end of the urinary catheter 1 close to the drug discharge port 5 Bag 7, and the end of the first inflation tube 6 is connected to the inside of the hemostatic bag 7, a second inflation tube 8 is provided at one end of the catheter 1 near the urination port 3 and symmetrically to the first inflation tube 6, a balloon 9 is provided at a position of the catheter 1 near the side hole 2, the end of the second inflation tube 8 is connected to the inside of the balloon 9, the balloon 9 is located between the hemostatic bag 7 and the drug discharge port 5, and elastic lines 11 are evenly provided between the inner wall of the balloon 9 and the outer side of the catheter 1, and the elastic lines 11 are arranged along the circumference of the catheter 1.
[0024] The overall working principle is as follows: when in use, the urinary catheter 1 is inserted into the bladder, the balloon 9 is located inside the bladder, and the hemostatic bag 7 is located at the prostate. The interior of the balloon 9 is first inflated through the second inflation tube 8. Since the inner wall of the balloon 9 has an elastic line 11 to pull, the air entering the balloon 9 can be evenly distributed, and the balloon 9 expands evenly. Then, the urinary catheter 1 is pulled outward to fit the balloon 9 at the urinary catheter port, and then the hemostatic bag 7 is inflated through the first inflation tube 6. The hemostatic bag 7 expands and compresses the prostate fossa to achieve the purpose of hemostasis.
[0025] In this embodiment, a conical sleeve 10 is fixed outside the urinary catheter 1 and between the hemostatic bag 7 and the balloon 9 . The open end of the conical sleeve 10 is connected to the balloon 9 , and the balloon 9 is in communication with the interior of the conical sleeve 10 .
[0026] Local working principle: during the expansion of the balloon 9, the conical sleeve 10 also expands simultaneously, forming one end of the balloon 9 into a cone shape, and when the catheter 1 is pulled outward and fixed, the conical sleeve 10 will be inserted into the inside of the large catheter opening, increasing the contact area with the catheter opening and improving the leak-proof effect.
[0027] In this embodiment, the thickness of the end of the conical sleeve 10 that contacts the urinary catheter 1 is greater than the thickness of the open end, and the thickness of the open end of the conical sleeve 10 is the same as the wall thickness of the balloon 9 .
[0028] Partial working principle: Since the wall thickness of the open end of the conical sleeve 10 is smaller than the wall thickness of the other end, the conical sleeve 10 can be ensured to form a cone when it expands, so as to be inserted into the interior of the urinary catheter.
[0029] In this embodiment, the outer side of the urinary catheter 1 is evenly provided with scale marks along the length direction.
[0030] Local working principle: During the insertion of the catheter 1, the insertion depth can be determined to prevent the front end of the catheter 1 from causing a large impact on the inner wall of the patient's bladder.
[0031] In this embodiment, a sponge cover 12 is slidably provided at one end of the urinary catheter 1 close to the urination port 3 , and a cotton pad 13 is provided at one end of the sponge cover 12 close to the hemostatic bag 7 .
[0032] Local working principle: After the urinary catheter 1 is fixed, the sponge sleeve 12 is controlled to move toward the urethral opening, and the cotton pad 13 is attached to the outside of the urethral opening to absorb the leaked urine.
[0033] In this embodiment, a tangent line is formed on the outer side of the sponge cover 12 , and the tangent line extends to the inner ring of the sponge cover 12 .
[0034] Partial working principle: After the sponge cover 12 absorbs more urine, the sponge cover 12 is unfolded from the tangent line and replaced with a new sponge cover 12.
[0035] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
