[0003] A triple lumen catheter is a medical device used to guide urine out of the body. It has three separate chambers, one for urine drainage and two for flushing and medication infusion. This design helps provide more flexible treatment and maintenance options, especially for patients who need regular flushing or medication infusion.

[0004] During the process of flushing the patient's bladder, the bladder is generally flushed by injecting liquid medicine into the bladder from a three-lumen catheter. During this process, the liquid medicine flows into the patient's bladder, which may cause discomfort to the patient. In some existing technologies, the flow rate of the liquid medicine in the three-lumen catheter cannot be adjusted. During flushing, the flow rate may be too fast, which may cause excessive impact on the patient's bladder, thereby making the patient more uncomfortable. Therefore, a three-lumen catheter that is easy to flush is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a three-lumen urinary catheter that is easy to flush, including a urinary catheter 1. The urinary catheter 1 is a three-lumen urinary catheter, which is a prior art well known to professionals in the field and will not be described in detail herein. The outer wall of the urinary catheter 1 is fixedly connected with a fixing block 4, which is the same size as the urinary catheter 1 and is made of a hard material. When the urinary catheter 1 is connected to the connecting block 201, the fixing block 4 moves along the inner wall of the connecting block 201, and can squeeze the clamping block 301 to flip the clamping block 301. The outer wall of the urinary catheter 1 is detachably installed with an adjusting mechanism 2, through which the medicine can be input from the urinary catheter 1 into the patient's bladder for flushing, and the flow rate of the medicine can be adjusted to prevent the patient from having bladder discomfort during flushing.

[0033] Reference Figure 1-Figure 2The regulating mechanism 2 includes a connecting block 201, the inner wall of which contacts the outer wall of the urinary catheter 1, and the connecting block 201 is a device for infusing and flushing drugs. The front end of the connecting block 201 is connected to a drug inlet tube, and the inner wall of the connecting block 201 is slidably connected to a baffle 202. The baffle 202 is circular, and the inner diameter of the middle end of the connecting block 201 is larger than the inner diameters of the front and rear ends, so that the baffle 202 is not blocked when it is flipped. The outer wall of the baffle 202 is fixedly connected to a long rod 203, and the long rod 203 passes through the outer wall of one side of the connecting block 201. By rotating the long rod 203, the baffle 202 can be driven to flip. When the baffle 202 flips to different angles, the size of the gap between it and the inner wall of the connecting block 201 can be adjusted, thereby limiting the flow speed of the medicine.

[0034] Reference Figure 1-Figure 2 The outer wall of the long rod 203 is fixedly connected to the square plate 208, and the outer wall of the square plate 208 is elastically connected to the moving block 205 through the spring A204. When the moving block 205 is rotated, the square plate 208 can be driven to rotate synchronously, and the long rod 203 and the baffle 202 can be driven to rotate. One end of the spring A204 is fixedly connected to the inner wall of the moving block 205, and the other end of the spring A204 is fixedly connected to the outer wall of the square plate 208. When not affected by external force, the elastic force of the spring A204 itself drives the moving block 205 to maintain contact with the outer wall of the connecting block 201.

[0035] Reference Figure 1-Figure 2 The outer wall of the square plate 208 is slidably connected to the inner wall of the moving block 205. The operator can pull the moving block 205 outward to force the spring A204 to contract. At this time, the block 206 is out of contact with the slot 207, and the limit of the moving block 205 can be released. The moving block 205 is rotated, and the outer wall of the moving block 205 is in contact with the outer wall of the connecting block 201. In this state, the block 206 is engaged with the slot 207, and the moving block 205 can be fixed, thereby fixing the baffle 202 and fixing the flow speed of the medicine.

[0036] Reference Figure 1-Figure 2 The outer wall of the moving block 205 is fixedly connected with a clamping block 206, and the outer wall of the connecting block 201 is provided with a plurality of clamping grooves 207, and the clamping block 206 is clamped with the clamping grooves 207. The clamping grooves 207 are arranged in a circular array on the outer wall of the connecting block 201, and the setting of the plurality of clamping grooves 207 can make the moving block 205 rotate to a plurality of positions for fixing. The inner wall of the connecting block 201 is provided with a clamping mechanism. When the connecting block 201 is inserted into the inside of the urinary catheter 1, the clamping mechanism can clamp the urinary catheter 1, thereby sealing it to prevent urine or medicine from leaking out and requiring cleaning, which is more troublesome.

[0037] Reference Figure 3-Figure 4The clamping mechanism includes a clamping block 301, which is semicircular and symmetrically distributed on the upper and lower inner walls of the connecting block 201. The inner wall of the clamping block 301 contacts the outer wall of the urinary catheter 1. The clamping block 301 can squeeze the urinary catheter 1 so that the urinary catheter 1 is tightly connected to the outer wall of the circular tube 304 inside the connecting block 201 to avoid leakage. The clamping block 301 is elastically connected to the inner wall of the connecting block 201 by a spring B302. Both the clamping block 301 and the spring B302 are inclined to facilitate the insertion of the urinary catheter 1 into the connecting block 201. One end of the spring B302 is fixedly connected to the connecting block 201. The inner wall of the connecting block 201, the other end of the spring B302 is fixedly connected to the outer wall of the clamping block 301. When the catheter 1 is inserted into the connecting block 201, the fixing block 4 squeezes the inclined clamping block 301, so that the clamping block 301 flips along the hinge between it and the connecting seat 303. When the fixing block 4 moves to break away from the clamping block 301, the clamping block 301 flips to a state of being in contact with the outer wall of the catheter 1. At this time, the spring B302 is tilted and contracted by force, thereby squeezing and closing the catheter 1. When the catheter 1 needs to be separated from the connecting block 201, it only needs to be pulled out with force.

[0038] Reference Figure 3-Figure 4 The inner wall of the connecting block 201 is fixedly connected with the connecting seat 303, and the outer wall of the clamping block 301 is hinged with the inner wall of the connecting seat 303, so that the clamping block 301 can be kept in an inclined state when not in use. The inner wall of the connecting block 201 is fixedly connected with the round tube 304, and the outer wall of the round tube 304 contacts the inner wall of the urinary catheter 1. When flushing, the urinary catheter 1 is inserted into the connecting block 201 and sleeved on the outer wall of the round tube 304. The clamping block 301 squeezes the outer wall of the urinary catheter 1, so that the urinary catheter 1 and the outer wall of the round tube 304 fit tightly, thereby avoiding leakage and improving the sealing performance.

[0039] Working principle: before flushing is required, the operator can insert one end of the catheter 1 into the connecting block 201 and put it on the outer wall of the circular tube 304. During the process of inserting the catheter 1 into the connecting block 201, the fixed block 4 on the outer wall of the catheter 1 squeezes the clamping block 301, causing the clamping block 301 to flip along the hinge between it and the connecting seat 303, and the spring B302 is forced to tilt and shrink. When the catheter 1 is inserted into the connecting block 201, the fixed block 4 is disengaged from the clamping block 301, and the clamping block 301 rebounds and flips due to the elastic force of the spring B302 itself, driving the clamping block 301 to flip and fit tightly with the outer wall of the catheter 1, squeezing the outer wall of the catheter 1, so that the catheter 1 and the outer wall of the circular tube 304 fit tightly, thereby improving the sealing between the catheter 1 and the connecting block 201, and avoiding the problem of drug leakage and waste, or flowing to the ground and needing to be cleaned when the medicine is poured for flushing.

[0040] After the connection is completed, the medicine can be injected from the medicine inlet tube arranged on the outer wall of the connecting block 201, flow into the urinary catheter 1 through the connecting block 201, and flush the patient's bladder. When the flow rate of the medicine is too large and causes discomfort to the patient and the flow rate of the medicine needs to be adjusted, the moving block 205 can be pulled outward to disengage the clamping block 206 from the clamping slot 207, so that the limit of the moving block 205 can be released, and then the moving block 205 can be rotated to drive the square plate 208 to rotate. The square plate 208 drives the long rod 203 and the baffle 202 to rotate, so that the size of the gap between the baffle 202 and the inner wall of the connecting block 201 can be adjusted, thereby adjusting the flow rate of the medicine, so as to adjust the impact force of the medicine on the inside of the patient's bladder and reduce the patient's discomfort.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
