Technical Field

[0001] The utility model belongs to the technical field of urinary catheter dredging, and particularly relates to a urinary catheter dredging device for preventing blockage. Background Art

[0002] A urinary catheter is a tube inserted into the bladder through the urethra for draining urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an airbag near the head end of the urinary catheter to fix the urinary catheter in the bladder and prevent it from slipping out easily. The drainage tube is connected to a urine bag to collect urine.

[0003] Urinary catheter blockage is a very common medical emergency. Medical staff need to use a urinary catheter dredging device. Since the urinary catheter is relatively long, it is difficult to dredge it with conventional conduction instruments. At present, the mainstream method is to use normal saline for bladder irrigation. Due to different situations, different irrigation pressures are required, and different irrigation tools will be selected. For traditional urinary catheter dredging devices, their adaptability to different types / sizes of irrigation tools is relatively low and they are inconvenient to use. Summary of the Utility Model

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0028] In an embodiment of the present utility model, a urinary catheter dredging device for preventing blockage is provided for dredging the urinary catheter 100, as Figures 1-3 shown. The urinary catheter dredging device for preventing blockage includes a urinary catheter 100. One end of the urinary catheter 100 has a urinary catheter head 103, and the other end of the urinary catheter 100 has a urine outlet tube 101 and a flushing tube 105. Among them, a balloon 104 is further provided on the urinary catheter 100 so that the urinary catheter is fixed in the patient's bladder. When the patient needs to urinate, the urine in the bladder is drained to the urine outlet tube 101 through the urinary catheter 100 for discharge.

[0029] Correspondingly, the urinary catheter 100 of the present utility model adopts a three-chamber structure. One chamber is the main chamber for urine drainage; another chamber is connected to the flushing tube 105 for injecting flushing liquid; and another chamber is connected to the inflation tube 106. The inflation tube 106 is used to inject air into the balloon 104, and an inflation valve is provided at the interface of the inflation tube 106 so that the air injected into the balloon 104 can be pressurized to keep the balloon 104 in a full state.

[0030] Please continue to refer to Figures 1-3, the catheter dredging device for preventing blockage in the embodiment of the present utility model further includes a flushing connector 200 adaptively connected to the flushing tube 105;

[0031] It further includes a urine collection bag 102. The urine collection bag 102 is connected to the end of the urine outlet tube 101 through a urine collection tube 1021, and a control valve 1022 is provided on the urine collection tube 1021.

[0032] It further includes a liquid injection tool 300. The liquid injection tool 300 is connected to the flushing connector 200 and is used to inject flushing liquid into the flushing tube 105. Preferably, the flushing liquid is prepared physiological saline; the liquid injection tool 300 can be a syringe. Since syringes have different sizes, the pressure generated by pushing the piston is also different. Specifically, the smaller the syringe 300, the greater the pressure; for example: the pushing pressure of a 1 ml ordinary syringe is 0.05 MPa; the pushing pressure of a 2.5 ml ordinary syringe is 0.03 MPa; the pushing pressure of a 5 ml ordinary syringe is 0.02 MPa, and the pushing pressure of a 10 ml ordinary syringe is 0.01 MPa; in addition, the liquid injection tool 300 of the present utility model can also be in other forms, such as using an infusion bottle for flushing; using a bladder irrigator or a large syringe for flushing; using a gastric irrigation device to extract bladder flushing liquid and connecting the catheter for flushing, etc. The flushing connector 200 adopted by the present utility model is used to connect with various liquid injection tools 300 of different sizes until it is flushed through; this avoids the patient from experiencing the process of re-catheterization in subsequent nursing, reduces the risk of infection, avoids related complications, alleviates the pain of the patient, reduces the economic pressure, and increases the satisfaction of the patient and his family.

[0033] As Figures 4-6 shown, in the embodiment of the present utility model, the flushing connector 200 includes a circular seat 201. One side of the circular seat 201 has a flushing outlet nozzle 2011, and the other side of the circular seat 201 has a flushing inlet nozzle 2012. The flushing outlet nozzle 2011 is connected to the flushing tube 105, and the flushing outlet nozzle 2011 communicates with the flushing inlet nozzle 2012. After the flushing liquid is injected into the circular seat 201 through the flushing inlet nozzle 2012, it is injected into the flushing tube 105 and the catheter 100 through the flushing outlet nozzle 2011; among them, when injecting the flushing liquid, it is necessary to first close the control valve 1022 on the urine outlet tube 101 to prevent the flushing liquid from directly entering the urine collection bag 102 from the urine outlet tube 101.

[0034] Furthermore, in the embodiment of the present utility model, a support shaft 202 is coaxially and fixedly arranged on the circular seat 201; the flushing connector 200 further includes a plurality of supports 204. Each support 204 is fixedly installed on a corresponding support rod 203, and the end of the support rod 203 is rotatably sleeved on the support shaft 202, so that the support 204 can move around the outer circumference of the circular seat 201.

[0035] In the embodiments of the present utility model, a connector 205 is threadedly connected to each support 204. Each connector 205 is provided with an injection port 2051 and a flushing port 2052. The sizes of all the flushing ports 2052 are the same, and the flushing port 2052 is adapted to the flushing inlet nozzle 2012. The sizes of each injection port 2051 are different to adapt to different types or sizes of liquid injection tools 300.

[0036] Therefore, for the liquid injection tool 300 of the required size, during use, a suitable connector 205 is selected. Then the connector 205 is moved to align with the flushing inlet nozzle 2012. Then, by adjusting the position of the connector 205 on the support 204, the connector 205 is moved to connect the flushing port 2052 with the flushing inlet nozzle 2012. At this time, the liquid injection tool 300 to be used can be connected to the injection port 2051 to achieve the injection of the flushing liquid.

[0037] The connector 205 of the present utility model is arranged on the support 204 by a threaded connection method. Therefore, the connector 205 can be rotated to adjust the position of the connector 205 on the support 204 according to the rotation direction. Furthermore, the flushing port 2052 can be connected to the corresponding flushing inlet nozzle 2012, or the flushing port 2052 connected to the flushing inlet nozzle 2012 can be moved away.

[0038] In summary, the present utility model can select liquid injection tools 300 of different sizes as needed to inject flushing liquid into the urinary catheter 100, with a wide range of applications, ensuring the flushing effect and being convenient to use.

[0039] The above solutions are only illustrations of a preferred example, but are not limited thereto. When implementing the present utility model, appropriate replacements and / or modifications can be made according to the needs of the user.
