Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, in particular to a medical safety balloon urinary catheter. Background Art

[0002] A urinary catheter is a tubular device used to guide urine out of the body. It is usually inserted into the urethra to draw urine out of the bladder. There are many types of catheters, and a urinary catheter with a safety balloon is a common type of catheter. The characteristic of this type of catheter is that it has a balloon that can be inflated by injecting a certain amount of liquid (usually saline). The inflated balloon can fix the catheter and prevent it from accidentally falling off.

[0003] The utility model with the existing authorization announcement number CN209596381U3 discloses a safe urinary catheter, which is provided with a scale and a second balloon, so that medical staff can timely observe the exposure of the urinary catheter and whether the first balloon is ruptured when caring for the patient, thereby reducing adverse events caused by the inability to timely judge the condition of the urinary catheter.

[0004] Although the above technical solution can timely observe the exposure of the catheter and whether the first balloon is ruptured, the above technical solution lacks an anti-reflux structure to prevent urine reflux, which makes the catheter prone to increased risk of urinary tract infection due to urine reflux in actual use.

[0005] Therefore, those skilled in the art provide a medical safety balloon catheter to solve the problems raised in the above background technology. Utility Model Content

[0006] The utility model aims to provide a medical safety balloon catheter to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A medical safety balloon catheter comprises a soft urinary catheter body, wherein an anti-backflow mechanism is arranged below the soft urinary catheter body;

[0009] The anti-backflow mechanism includes a storage hard tube, the bottom end of the storage hard tube is fixedly connected to a connecting hose, a blocking ball is arranged inside the storage hard tube, the inner wall of the storage hard tube is respectively fixedly connected to a baffle plate and a leakage plate, the bottom surface of the baffle plate is fixedly connected to an elastic pad, and the upper surface of the leakage plate is respectively provided with a limiting hole and two leakage holes.

[0010] As a further solution of the utility model: the top end of the storage hard tube is fixedly connected to the bottom end of the soft urinary catheter body, the outer surface of the elastic pad is fixedly connected to the inner wall of the baffle, the outer surface of the soft urinary catheter body is fixedly connected to a liquid delivery hose, the top end of the liquid delivery hose is fixedly connected to a soft balloon, and the inner wall of the soft balloon is fixedly connected to the outer surface of the soft urinary catheter body.

[0011] As a further solution of the utility model: the top end of the soft urinary catheter body is fixedly connected with a soft liquid inlet head, and the outer surface of the soft liquid inlet head is provided with two groups of liquid inlet holes.

[0012] As a further solution of the utility model: the bottom end of the connecting hose is fixedly connected to a supporting hard tube, and the outer surface of the supporting hard tube is fixedly connected to a first anti-slip sleeve.

[0013] As a further solution of the utility model: the outer surface of the liquid delivery hose is fixedly connected to a liquid inlet hard pipe, the outer surface of the liquid inlet hard pipe is fixedly connected to an elastic anti-skid wrapping sleeve, and the inner wall of the elastic anti-skid wrapping sleeve is fixedly connected to the inner wall of the liquid inlet hard pipe.

[0014] As a further solution of the utility model: a second anti-skid sleeve is fixedly connected to the outer surface of the liquid inlet hard pipe, and a plurality of identical anti-skid protrusions are fixedly connected to the outer surface of the second anti-skid sleeve.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model uses the mutual cooperation of the soft urinary catheter body, the storage hard tube, the connecting hose, the flow-blocking ball, the baffle plate, the elastic pad, the leakage plate, the limiting hole and the leakage hole to place the two ends of the storage hard tube horizontally for use. After the soft urinary catheter body is extended into the urethra, it can guide the patient's urine to the storage hard tube. Then, after the urine enters the storage hard tube from the soft urinary catheter body, the urine impacts the flow-blocking ball and makes the flow-blocking ball hit the limiting hole and then flows from the leakage hole to the connecting hose. When urine refluxes, the refluxed urine can rush the flow-blocking ball to the elastic pad of the baffle plate, so that the flow-blocking ball can block the through hole of the baffle plate to prevent urine reflux, thereby preventing urine reflux and reducing the risk of urinary tract infection, avoiding the problem that the risk of urinary tract infection due to urine reflux in actual use of the urinary catheter is increased due to urine reflux due to the lack of an anti-reflux structure to prevent urine reflux.

[0023] A flow-blocking ball 203 is arranged inside the storage hard tube 201, and the top of the soft urinary catheter body 1 is fixedly connected with a soft liquid inlet head 5, and two groups of liquid inlet holes 6 are opened on the outer surface of the soft liquid inlet head 5. By providing the soft liquid inlet head 5, the outer surface itself is relatively round and soft, which can increase the roundness of the top of the soft urinary catheter body 1, thereby increasing the comfort of use of the entire urinary catheter, and by providing the liquid inlet holes 6, urine can flow into the inside of the soft urinary catheter body 1 from multiple directions.

[0024] The inner wall of the storage hard tube 201 is fixedly connected with a baffle plate 204 and a leakage plate 206 respectively, the bottom end of the connecting hose 202 is fixedly connected with a supporting hard tube 7, and the outer surface of the supporting hard tube 7 is fixedly connected with a first anti-slip sleeve 8. By providing the supporting hard tube 7, the hardness of the bottom end of the connecting hose 202 can be increased, thereby facilitating the docking of the external tube body structure of the extended catheter. By providing the first anti-slip sleeve 8, the friction force of the outer surface of the supporting hard tube 7 can be increased. At the same time, when the external extended catheter body is docked with the supporting hard tube 7, the sealing between the two is increased to prevent leakage at the connection between the two.

[0025] The bottom surface of the baffle plate 204 is fixedly connected with an elastic pad 205, the outer surface of the elastic pad 205 is fixedly connected to the inner wall of the baffle plate 204, the outer surface of the liquid delivery hose 3 is fixedly connected with a liquid inlet hard tube 9, the outer surface of the liquid inlet hard tube 9 is fixedly connected with an elastic anti-skid wrapping sleeve 10, the inner wall of the elastic anti-skid wrapping sleeve 10 is fixedly connected to the inner wall of the liquid inlet hard tube 9, by providing the liquid inlet hard tube 9, it is not easy to deform, and it is convenient to connect with an external syringe, by providing the elastic anti-skid wrapping sleeve 10, it itself has good elasticity and anti-skid properties, and then it is convenient to wrap the syringe head containing physiological saline on the outside, thereby increasing the stability of the syringe when injecting physiological saline into the liquid inlet hard tube 9 and the liquid delivery hose 3.

[0026] A limiting hole 207 and two leakage holes 208 are respectively provided on the upper surface of the leakage tray 206. A second anti-slip sleeve 11 is fixedly connected to the outer surface of the liquid inlet hard tube 9. A plurality of identical anti-slip bosses 12 are fixedly connected to the outer surface of the second anti-slip sleeve 11. The anti-slip bosses 12 can increase the friction force on the outer surface of the second anti-slip sleeve 11. The second anti-slip sleeve 11 and the anti-slip bosses 12 can increase the friction force on the outer surface of the liquid inlet hard tube 9 together, making it convenient for one hand to stably hold the liquid inlet hard tube 9 and the other hand to use a syringe with saline.

[0027] The working principle of the utility model is as follows: when in use, first insert the soft liquid inlet head 5 with the soft balloon 4, the liquid delivery hose 3 and the soft urinary catheter body 1 into the patient's urethra. When the soft liquid inlet head 5 is inserted into the appropriate position of the urethra, one hand pinches the second anti-skid sleeve 11 and the anti-skid convex column 12 on the outer surface of the liquid inlet hard tube 9, and the other hand uses a syringe filled with physiological saline to inject physiological saline into the liquid inlet hard tube 9 and the liquid delivery hose 3. The physiological saline quickly enters the soft balloon 4 through the liquid delivery hose 3 to expand the soft balloon 4. After the expanded soft balloon 4 is fixed in the patient's urethra, the patient's urine passes through the soft liquid inlet head 5, the liquid inlet hole 6 and the soft urinary catheter body 1 and then enters the interior of the storage hard tube 201. Then the urine flushes the flow-blocking ball 203 to the position of the limiting hole 207 on the leakage plate 206, and the urine passes through the leakage plate 20 The leakage hole 208 on 6 continues to flow to the connecting hose 202 and the supporting hard tube 7. If necessary, an external extension tube is used to connect with the first anti-slip sleeve 8 on the outer surface of the supporting hard tube 7, so that urine can flow out smoothly. During this period, the two ends of the storage hard tube 201 can be kept in a horizontal state. When urine flows back to the inside of the soft urinary catheter body 1, a small section of the backflow urine will rush the blocking ball 203 to the baffle 204 and the elastic pad 205. The blocking ball 203 is tightly pressed by the impact of the backflow of urine to block the hole in the middle of the baffle 204, preventing the urine from further backflowing and preventing the occurrence of infection. The design of the entire medical safety balloon catheter effectively solves the problem that the catheter is prone to increase the risk of urinary tract infection due to urine backflow in actual use due to the lack of an anti-backflow structure to prevent urine backflow.

[0028] What is described above is only a preferred specific implementation manner 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 technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
