Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a urethra-cleaning catheter. Background Art

[0002] With the development of industrial technology, modern medical equipment technology has become more and more perfect. For patients who need long-term general anesthesia surgery, in order to relieve urine pressure, it is necessary to use a catheter to penetrate deep into the bladder to urinate;

[0003] Patent No. 202411080017.2 discloses a urethra-cleaning catheter, comprising a urine drainage tube, wherein a urethral rinsing liquid delivery channel is provided on the urine drainage tube (1), wherein the urethral rinsing liquid delivery channel is provided with one or more urethral rinsing liquid discharge ports on the outer wall of the tube section of the urine drainage tube located in the human urethra, and the urethral rinsing liquid is delivered to the space between the inner surface of the human urethra and the outer surface of the urine drainage tube through the urethral rinsing liquid delivery channel, and the urethral rinsing liquid entering the space between the inner surface of the human urethra and the outer surface of the urine drainage tube rinses the human urethra, and then the urethral rinsing liquid flows out through the channel between the human urethra and the outer wall of the urine drainage tube. The purpose is to provide a urethra-cleaning catheter that can timely remove secretions in the urinary tract implanted with the catheter by flushing, timely and efficiently remove bacterial biota formed in the human urethra, and thereby avoid or reduce infection in the urinary tract implanted with the catheter.

[0004] The catheter has the following defects when in use. First, the structure of the catheter is relatively complicated, and it is difficult to implant the catheter into the human body, which increases the pain of the patient. Second, for patients with cystitis, there may be pus and blood clots inside the patient's bladder. The diameter of the catheter is relatively thin, which is easily blocked by pus and blood clots, which is not conducive to the discharge of pus and blood by the patient. Summary of the invention

[0005] The object of the present invention is to provide a urethra-cleaning catheter. When the device is in use, the catheter head is inserted into the patient's urethral opening. At this time, the soft catheter will be squeezed by the patient's urethra and fit on the surface of the crescent tube, so that the soft catheter will reduce the local pressure on the urethra, thereby increasing the patient's comfort. The inner arc surface of the crescent tube will not be blocked by the contraction of the soft catheter, so that there is still space for catheterization when the soft catheter is compressed again. During the implantation of the soft catheter, a syringe is used to start pumping air at the tail end of the suction wire tube. The suction eye on the top surface of the catheter head can drill into the urethra more smoothly under negative pressure, thereby reducing the obstacles to the implantation of the soft catheter. After the catheter head is inserted into the bladder, urine flows out from the blocking port, and at the same time, the suction wire tube and the detection wire tube are pulled, so that the expansion bag is compressed and expanded and locked in the opening of the bladder, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a urethra-cleaning catheter, comprising a soft urethra-cleaning catheter, a catheter head is arranged at the top of the soft urethra-cleaning catheter, an expansion bag is arranged between the soft urethra-cleaning catheter and the catheter head, and a bifurcated tube is arranged at the bottom of the soft urethra-cleaning catheter; the interior of the catheter head is a solid plastic block, the top of the catheter head is a hemispherical head, a sealing port is also arranged on the side wall of the catheter head, a suction wire tube and a detection wire tube are drawn out from the bottom of the catheter head, the suction wire tube and the detection wire tube pass through the interior of the soft urethra-cleaning catheter, the suction wire tube and the detection wire tube turn from the node of the soft urethra-cleaning catheter and the bifurcated tube and pass out from the tail end of the bifurcated tube; a sealing port is arranged on the side wall of the catheter head, and a pus and blood extraction mechanism is arranged inside the sealing port.

[0007] Furthermore, the suction wire tube and the detection wire tube are plastic straws whose cross sections cannot be flattened, and the suction wire tube and the detection wire tube are not ductile.

[0008] Furthermore, the bottom end of the bifurcated tube is provided with two notches, the suction wire tube and the detection wire tube are respectively inserted into the two notches, and the suction wire tube and the detection wire tube are wound and locked on the outer side wall of the bifurcated tube outside the notches.

[0009] Furthermore, the pus and blood extraction mechanism includes a sealing head, the edge of the inner port of the sealing port is provided with a hollow frame in a circular array, a crescent tube is provided on the inner wall of the sealing head, the crescent tube passes through the middle of the hollow frame, a suction channel is provided inside the crescent tube, the crescent tube passes through the tail end of the soft urinary catheter, and the front port of the suction channel opens to the outer wall of the sealing head.

[0010] Furthermore, the outer side wall of the plugging head is a curved surface, and the curved surface of the outer side wall of the plugging head matches the outer curved surface of the catheterization head, and the rear port of the suction channel can be connected to the pump body.

[0011] Furthermore, an airway is arranged at the center of the catheter head, an air pressure ball is arranged at the top of the airway, and the bottom end of the airway is connected to the detection wire tube.

[0012] Furthermore, the tail end of the detection wire tube is connected to an air pressure detector.

[0013] Furthermore, a circular array of air suction eyes is arranged on the hemispherical head at the top of the catheter head, and the bottom ends of the air suction eyes are bundled together and connected to an air suction wire tube, and the air suction wire tube is connected to a syringe.

[0014] In summary, due to the adoption of the above technology, the beneficial effects of the present invention are:

[0015] Firstly, when the device is in use, the catheter head is inserted into the patient's urethral opening. At this time, the soft catheter will be squeezed by the inside of the patient's urethra and fit on the surface of the crescent canal, so that the soft catheter will reduce the local pressure on the urethra and increase the patient's comfort. The inner arc surface of the crescent canal will not be blocked by the contraction of the soft catheter, so that there is still space for catheterization when the soft catheter is compressed again. During the implantation of the soft catheter, a syringe is used to start suction at the tail end of the suction wire tube. The suction hole on the top surface of the catheter head can drill into the urethra more smoothly under negative pressure, thereby reducing the obstacles to the implantation of the soft catheter. After the catheter head is inserted into the bladder, urine flows out from the blocking port, and at the same time, the suction wire tube and the detection wire tube are pulled, so that the expansion bag is compressed and expanded and locked in the opening of the bladder.

[0016] Secondly, the air pressure ball detects the pressure inside the bladder and transmits it to the air pressure detector through the detection wire tube. If the pressure detected by the air pressure detector is too high, it means that the pus and blood clots inside the bladder have blocked the sealing port. At this time, the suction channel of the crescent tube is connected to the high-powered pump, and the crescent tube is pushed forward a short distance to allow the sealing head at its end to be inserted into the sealing port. The high-powered pump applies high negative pressure to the suction channel of the crescent tube to forcibly suck out the pus and blood clots inside. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] The present invention provides Figure 1-Figure 6 The urethra-cleaning catheter shown in the figure is characterized in that it comprises a soft urethra-cleaning catheter 1, a catheter head 4 is arranged at the top of the soft urethra-cleaning catheter 1, an expansion bag 3 is arranged between the soft urethra-cleaning catheter 1 and the catheter head 4, and a bifurcated tube 2 is arranged at the bottom of the soft urethra-cleaning catheter 1; the interior of the catheter head 4 is a solid plastic block, the top of the catheter head 4 is a hemispherical head, and a sealing port 403 is also arranged on the side wall of the catheter head 4, and a suction wire tube 6 and a detection wire tube 7 are pulled out from the bottom of the catheter head 4, and the suction wire tube 6 and the detection wire tube 7 pass through the interior of the soft urethra-cleaning catheter 1, and the suction wire tube 6 and the detection wire tube 7 turn from the node of the soft urethra-cleaning catheter 1 and the bifurcated tube 2 and pass through the tail end of the bifurcated tube 2; the catheter head A sealing port 403 is provided on the side wall of 4, and a pus and blood extraction mechanism is provided inside the sealing port 403. The catheter head 4 is inserted into the patient's urethra. After the catheter head 4 is sent into the bladder, urine flows out from the sealing port 403. At the same time, the suction wire tube 6 and the detection wire tube 7 are pulled. At this time, the catheter head 4 and the soft urinary catheter 1 will be close to each other, and then the expansion balloon 3 will be compressed and expanded to be locked in the opening of the bladder. Compared with the bladder locking mechanism of the prior art, after the previous urinary catheter is implanted into the bladder, there will be a water-filled and swollen balloon at the end of the catheter to seal the bladder opening. The volume of this sealing balloon is relatively large and there is a risk of rupture. The volume of the expansion balloon 3 of the present invention is relatively effective after being flattened, and there is no risk of rupture.

[0027] The suction wire tube 6 and the detection wire tube 7 are plastic straws whose cross sections cannot be flattened. The suction wire tube 6 and the detection wire tube 7 are not ductile. Pulling the suction wire tube 6 and the detection wire tube 7 applies traction force to the catheter head 4 to compress the expansion bag 3. The suction wire tube 6 and the detection wire tube 7 are not ductile to prevent the expansion bag 3 from rebounding.

[0028] The bottom end port of the bifurcated tube 2 is provided with two notches, and the suction wire tube 6 and the detection wire tube 7 are respectively inserted into the two notches, and the suction wire tube 6 and the detection wire tube 7 are wound and locked on the outer wall of the bifurcated tube 2. After the suction wire tube 6 and the detection wire tube 7 are pulled and positioned, the suction wire tube 6 and the detection wire tube 7 are pressed into the two notches and wound and locked.

[0029] The pus and blood extraction mechanism includes a sealing head 5, and the edge of the inner port of the sealing port 403 is provided with a hollow frame 501 in a circular array, and a crescent tube 502 is provided on the inner wall of the sealing head 5. The crescent tube 502 passes through the middle of the hollow frame 501, and a suction channel 503 is provided inside the crescent tube 502. The crescent tube 502 passes through the tail end of the soft urinary catheter 1, and the front end of the suction channel 503 opens to the outer wall of the sealing head 5. The soft urinary catheter 4 will be squeezed by the inside of the patient's urethra and fit on the surface of the crescent tube 502, so that the soft urinary catheter 1 will reduce the local pressure on the urethra and increase the comfort of the patient. The inner arc surface of the crescent tube 502 will not be blocked by the contraction of the soft urinary catheter 1. Compared with the catheter in the prior art, the previous catheter has certain toughness and strength, and the pressure on the urethra during the implantation of the catheter will cause pain.

[0030] The outer wall of the plugging head 5 is an arc surface, and the arc surface of the outer wall of the plugging head 5 matches the outer arc surface of the catheterization head 4. The rear port of the suction channel 503 can be connected to the pump body, and the suction channel 503 of the crescent tube 502 is connected to the powerful pump, and the crescent tube 502 is pushed forward a short distance to allow the plugging head 5 at its end to be inserted into the plugging port 403. The powerful pump applies high negative pressure to the suction channel 503 of the crescent tube 502 to forcibly suck out the pus and blood clots inside it.

[0031] An airway is arranged at the center of the catheter head 4, and an air pressure ball 402 is arranged at the top of the airway. The bottom end of the airway is connected to the detection wire tube 7. The air pressure ball 402 detects the pressure inside the bladder and transmits it through the detection wire tube 7, so as to detect the pressure inside the bladder and further detect whether the catheter is blocked.

[0032] The tail end of the detection wire tube 7 is connected to an air pressure detector. If the pressure detected by the air pressure detector is too high, it means that the pus and blood clots inside the bladder have blocked the sealing port 403.

[0033] A circular array of suction eyes 401 are arranged on the hemispherical head at the top of the catheter head 4, and the bottom ends of the suction eyes 401 are gathered together and connected to the suction wire tube 6, and the suction wire tube 6 is connected to the syringe. During the implantation process, the syringe is used to start suctioning at the tail end of the suction wire tube 6. The suction eyes 401 on the top surface of the catheter head can drill into the urethra more smoothly under negative pressure, thereby reducing the obstacles to the implantation of the soft catheter 1.

[0034] Working principle: insert the catheter head 4 from the patient's urethra, and after the catheter head 4 is inserted into the bladder, urine flows out from the blocking port 403, and at the same time, the suction wire tube 6 and the detection wire tube 7 are pulled, and the catheter head 4 and the soft urinary catheter 1 are closed, and then the expansion balloon 3 is compressed and expanded and locked in the bladder opening. Compared with the bladder locking mechanism of the prior art, after the previous urinary catheter is implanted into the bladder, there will be a water-filled balloon at the end of the catheter to seal the bladder opening. This blocking balloon is relatively large in size and has a rupture The expansion bag 3 of the present invention has a relatively small volume after being flattened, and there is no risk of rupture. The suction wire tube 6 and the detection wire tube 7 are pulled to apply traction to the catheter head 4 to compress the expansion bag 3. The suction wire tube 6 and the detection wire tube 7 are not ductile and can prevent the expansion bag 3 from rebounding. After the suction wire tube 6 and the detection wire tube 7 are pulled and positioned, the suction wire tube 6 and the detection wire tube 7 are pressed into the two notches and wrapped and locked. The soft urinary catheter 4 will be squeezed by the patient's urethra and fit on the surface of the crescent tube 502, so that the soft urinary catheter 1 will be reduced. The local pressure on the urethra increases the comfort of the patient. The inner arc surface of the crescent tube 502 will not be blocked by the contraction of the soft urinary catheter 1. Compared with the urinary catheters in the prior art, the previous urinary catheters have a certain toughness and strength, and the pressure on the urethra during the implantation of the urinary catheter will cause pain. The suction channel 503 of the crescent tube 502 is connected to the powerful pump, and the crescent tube 502 is pushed forward a short distance to allow the sealing head 5 at its end to be inserted into the sealing port 403. The powerful pump applies pressure to the suction channel 503 of the crescent tube 502. The high negative pressure forces the pus and blood clots inside to be sucked out. The air pressure ball 402 detects the pressure inside the bladder and transmits it through the detection wire tube 7, which is convenient for detecting the pressure inside the bladder, and then detecting whether the catheter is blocked. If the pressure detected by the air pressure detector is too high, it means that the pus and blood clots inside the bladder have blocked the sealing port 403. During the implantation process, a syringe is used to start suction at the tail end of the suction wire tube 6. The suction hole 401 on the top surface of the catheter head can drill into the urethra more smoothly under negative pressure, thereby reducing the obstacles to the implantation of the soft urinary catheter 1.
