Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a urinary catheter. Background Art

[0002] In existing medical processes, double-lumen urinary catheters are used in a relatively high proportion. The main structure of the catheter consists of three parts: the tube body, the tube head and the liquid outlet port. An injection tube is provided on one side of the liquid outlet port. The injection tube is provided with a one-way valve and is connected to the supporting air bag at the end of the catheter.

[0003] During long-term placement, existing catheters can become clogged due to the presence of coagulated blood clots and small stones in the urine. There are two common causes of blockage: The first is internal blockage within the catheter, which can be unblocked by inserting a syringe with a needle directly into the catheter's drainage lumen and impacting the catheter. The second is blockage within the urine bag's tubing connected to the catheter, which can be unblocked by pressing the drainage lumen at the end of the catheter or kneading the bag's tubing.

[0004] Since the two blockage situations require different treatment methods, the staff needs to distinguish the blockage situation in advance, which causes inconvenience in catheter unblocking and increases the workload of medical staff. In addition, the existing catheter cannot remind medical staff when blockage occurs, which makes the blockage time too long and leads to adverse consequences. Utility Model Content

[0005] The utility model provides a urinary catheter to solve the technical problem that the existing urinary catheter cannot remind medical staff when it is blocked, and the staff needs to identify the blockage in advance, which causes inconvenience in urinary catheter unblocking work and increases the workload of medical staff.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A urinary catheter comprises a tube body with a fixed balloon at the end thereof, a water injection pipe connected to the fixed balloon being provided on the side wall of the tube body, a water injection valve being provided at the end of the water injection pipe, and a liquid pressure sensor for detecting the pressure of the fixed balloon being provided inside the water injection pipe; a drainage cavity having an end portion that matches the pipeline interface of a urine bag at the end of the tube body away from the fixed ball valve; a liquid level sensor for detecting whether liquid is flowing is provided inside the tube body; the liquid level transducer is arranged between the drainage cavity and the water injection pipe; the water injection pipe and the tube body are each provided with an alarm reminder module connected to the liquid pressure sensor and the liquid level sensor.

[0008] Preferably, a first placement cavity is provided inside the water injection pipe, a first liquid passing cylinder is embedded inside the first placement cavity, a first liquid passing cavity is provided inside the first liquid passing cylinder, both ends of which are connected to the water injection pipe, and the sensing end of the liquid pressure sensor is arranged on the inner wall of the first liquid passing cavity.

[0009] Preferably, first sealing rings are respectively provided between both ends of the first liquid-passing cylinder and the first placement cavity.

[0010] Preferably, a second placement cavity is provided inside the tube body, a transparent second liquid-passing cylinder is embedded inside the second placement cavity, a second liquid-passing cavity is provided inside the second liquid-passing cylinder, and both ends of the second liquid-passing cylinder are connected to the tube body. The liquid level sensor is arranged inside the second liquid-passing cylinder, and the signal transmitting end and the signal receiving end of the liquid level sensor are docked and arranged on both sides of the first liquid-passing cavity.

[0011] Preferably, a second sealing ring is provided between both ends of the second liquid-passing cylinder and the second placement cavity.

[0012] Preferably, the alarm reminder module includes a signal light and a buzzer.

[0013] Preferably, a flushing tube is provided near the tube body, and a flushing interface matching the syringe is provided at the outer end of the flushing tube.

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

[0015] 1. The device is provided with a liquid pressure sensor for detecting the pressure of the fixed balloon inside the water injection pipe, and a liquid level sensor for detecting whether the liquid is flowing inside the tube body, thereby reminding medical personnel that the urinary catheter is blocked. Moreover, when the alarm reminder modules connected to the liquid pressure sensor and the liquid level sensor, respectively, provided in the water injection pipe and the tube body, both sound an alarm, it indicates that the first blockage situation has occurred, that is, the blockage has occurred inside the urinary catheter, thereby directly reminding medical personnel to take corresponding measures; when only the alarm reminder module connected to the liquid pressure sensor in the water injection pipe sounds an alarm, it indicates that the second blockage situation has occurred, that is, the blockage has occurred in the pipeline of the urine bag connected to the urinary catheter, thereby directly reminding medical personnel to take corresponding measures; therefore, the device can remind medical personnel when a blockage occurs, and does not require staff to distinguish the blockage situation in advance, thereby facilitating the unblocking of the urinary catheter and reducing the workload of medical personnel.

[0016] 2. When blockage occurs inside the catheter, medical staff can flush the catheter through the flushing interface on the outer end of the flushing tube that matches the syringe. There is no need to insert the needle syringe directly into the drainage cavity of the catheter and impact the catheter, which can avoid damage to the catheter caused by the needle.

Obviously, the described embodiment is only a partial embodiment of the present application, rather than an embodiment of the whole piece. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] The following combination Figures 1 and 2 The utility model is described in detail.

[0024] A urinary catheter, in some embodiments, such as Figures 1 and 2 As shown, it includes a tube body 2 with a fixed balloon 1 at the end, a water injection pipe 3 connected to the fixed balloon 1 is provided on the side wall of the tube body 2 near the other end of the tube body 2, and a water injection valve 4 is provided at the end of the water injection pipe 3. A liquid pressure sensor 5 for detecting the pressure of the fixed balloon 1 is provided inside the water injection pipe 3; the tube body 2 is provided with a drainage cavity 6 at the end away from the fixed ball valve, and one end of the drainage cavity 6 is provided with a port matching the pipeline interface of the urine bag; a liquid level sensor 7 for detecting whether the liquid is circulating is provided inside the tube body 2; the liquid flow transducer is arranged between the drainage cavity 6 and the water injection pipe 3; the water injection pipe 3 and the tube body 2 are each provided with an alarm reminder module connected to the liquid pressure sensor 5 and the liquid level sensor 7.

[0025] During specific use, the fixed balloon 1 on the tube body 2 is inserted into the patient's bladder through the urethra, and then a certain amount of liquid is filled into the fixed balloon 1 through the water injection valve 4 on the water injection pipe 3 to fix the tube body 2, and then the port is connected to the pipeline interface of the urine bag for drainage treatment; during the drainage process of urine, when the catheter is blocked, the urine in the patient's bladder cannot be discharged, and accumulates more and more, thereby increasing the pressure in the bladder. The increased pressure squeezes the fixed balloon 1 through the urine, thereby increasing the liquid pressure inside the fixed balloon 1. Since the water injection pipe 3 is connected to the fixed balloon 1, the pressure of the liquid in the water injection pipe 3 increases. At this time, the liquid pressure sensor 5 detects the pressure increase and thus detects the blockage of the catheter, and reminds through the alarm reminder module; At the same time, if the liquid level sensor 7 in the tube body 2 senses that there is no urine at the corresponding position in the tube body 2, it indicates that the first blockage situation has occurred, that is, blockage has occurred inside the catheter. At this time, the alarm reminder device connected to the liquid level sensor 7 issues an alarm, and the medical staff can use a syringe with a needle to directly insert the drainage cavity 6 of the catheter and impact the catheter to clear the catheter; if the liquid level sensor 7 in the tube body 2 senses that there is urine at the corresponding position in the tube body 2, it indicates that the second blockage situation has occurred, that is, blockage has occurred in the pipeline of the urine bag connected to the catheter. At this time, the alarm reminder device connected to the liquid level sensor 7 will not issue an alarm, and the medical staff needs to press the drainage cavity 6 at the end of the catheter or the pipeline of the urine bag to knead and press it to clear the blockage.

[0026] This device is provided with a liquid pressure sensor 5 inside the water injection pipe 3 for detecting the pressure of the fixed balloon 1, and a liquid level sensor 7 inside the tube body 2 for detecting whether the liquid is flowing, thereby reminding medical personnel that the catheter is blocked. Moreover, when the alarm reminder modules connected to the liquid pressure sensor 5 and the liquid level sensor 7, which are respectively provided in the water injection pipe 3 and the tube body 2, both sound an alarm, it indicates that the first blockage situation has occurred, that is, blockage has occurred inside the catheter, thereby directly reminding medical personnel to take corresponding measures; when only the alarm reminder module connected to the liquid pressure sensor 5 in the water injection pipe 3 sounds an alarm, it indicates that the second blockage situation has occurred, that is, blockage has occurred in the pipeline of the urine bag connected to the catheter, thereby directly reminding medical personnel to take corresponding measures; therefore, this device can remind medical personnel when blockage occurs, and does not require staff to distinguish the blockage situation in advance, which facilitates the unblocking of the catheter and reduces the workload of medical personnel.

[0027] In some embodiments, as Figures 1 and 2As shown, a first placement cavity 8 is provided inside the water injection pipe 3, a first liquid passing cylinder 9 is embedded inside the first placement cavity 8, a first liquid passing cavity 10 is provided inside the first liquid passing cylinder 9, both ends of which are connected to the water injection pipe 3, and the sensing end of the liquid pressure sensor 5 is arranged on the inner wall of the first liquid passing cavity 10.

[0028] During specific use, by setting the liquid pressure sensor 5 into the hard first liquid cylinder 9, the detection point of the liquid pressure is located in the hard pipeline (because the water injection pipe 3 is an elastic soft material, if it is directly installed inside the water injection pipe 3, when the liquid pressure is too high, the water injection pipe 3 at the installation location of the liquid pressure sensor 5 will swell, resulting in a small detection pressure), thereby improving the accuracy and stability of the detection.

[0029] In some embodiments, as Figures 1 and 2 As shown, first sealing rings 11 are respectively provided between the two ends of the first liquid-passing cylinder 9 and the first placement cavity 8 .

[0030] During specific use, liquid is prevented from entering the gap between the first liquid-passing cylinder 9 and the first placement cavity 8, which may cause deviation in the detection of liquid pressure.

[0031] In some embodiments, as Figures 1 and 2 As shown, the interior of the tube body 2 is provided with a second placement cavity 12, the interior of the second placement cavity 12 is embedded with a transparent second liquid-passing cylinder 13, and the second liquid-passing cylinder 13 is provided with a second liquid-passing cavity 14 whose two ends are connected to the tube body 2. The liquid level sensor 7 is arranged inside the second liquid-passing cylinder 13, and the signal transmitting end and the signal receiving end of the liquid level sensor 7 are docked and arranged on both sides of the first liquid-passing cavity 10. The liquid level sensor 7 adopts a non-contact laser liquid level sensor 7.

[0032] During specific use, by setting the liquid level sensor 7 into the hard second liquid cylinder 13, the detection point of urine is located in the hard pipeline, ensuring that the signal transmitting end and the signal receiving end of the liquid level sensor 7 are aligned (because the tube body 2 is an elastic soft material, if it is directly installed inside the tube body 2, it is easy to cause the signal transmitting end and the signal receiving end to be difficult to align), thereby improving the accuracy and stability of detection.

[0033] In some embodiments, as Figures 1 and 2 As shown, second sealing rings 15 are respectively provided between the two ends of the second liquid-passing cylinder 13 and the second placement cavity 12 .

[0034] During specific use, urine is prevented from entering the gap between the second liquid-passing cylinder 13 and the second placement cavity 12, which may cause deviation in the detection of liquid pressure.

[0035] In some embodiments, as Figures 1 and 2 As shown, the alarm reminder module includes a signal light 16 and a buzzer 17. The signal light 16 and the buzzer 17 are arranged inside the first liquid-passing cylinder 9 or the second liquid-passing cylinder 13.

[0036] In some other embodiments, different from the above embodiments, Figures 1 and 2 As shown, the tube body 2 is provided with a flushing tube 18 near the tube body, and the outer end of the flushing tube 18 is provided with a flushing interface 19 that matches the syringe.

[0037] During specific use, when blockage occurs inside the catheter, medical personnel can connect the syringe to flush the catheter through the flushing interface 19 at the outer end of the flushing tube 18 that matches the syringe. There is no need to directly insert the needle syringe into the catheter drainage cavity 6 and impact the catheter, thereby avoiding damage to the catheter by the needle.

[0038] The operating principle of this device:

[0039] The fixed balloon 1 on the tube body 2 is inserted into the patient's bladder through the urethra, and then a certain amount of liquid is filled into the fixed balloon 1 through the water injection valve 4 on the water injection pipe 3 to fix the tube body 2, and then the port is connected to the pipeline interface of the urine bag for drainage treatment; during the drainage process of urine, when the catheter is blocked, the urine in the patient's bladder cannot be discharged and accumulates more and more, thereby increasing the pressure in the bladder. The increased pressure squeezes the fixed balloon 1 through the urine, thereby increasing the liquid pressure inside the fixed balloon 1. Since the water injection pipe 3 is connected to the fixed balloon 1, the pressure of the liquid in the water injection pipe 3 increases. At this time, the liquid pressure sensor 5 detects the pressure increase and thus detects the blockage of the catheter, and reminds through the alarm reminder module; at the same time If the liquid level sensor 7 in the tube body 2 senses that there is no urine at the corresponding position in the tube body 2, it indicates that the first blockage situation has occurred, that is, blockage has occurred inside the urinary catheter. At this time, the alarm reminder device connected to the liquid level sensor 7 issues an alarm, and the medical staff can use a syringe with a needle to directly insert the drainage cavity 6 of the urinary catheter and impact the urinary catheter to unclog the urinary catheter; if the liquid level sensor 7 in the tube body 2 senses that there is urine at the corresponding position in the tube body 2, it indicates that the second blockage situation has occurred, that is, blockage has occurred in the pipeline of the urine bag connected to the urinary catheter. At this time, the alarm reminder device connected to the liquid level sensor 7 will not issue an alarm, and the medical staff needs to press the drainage cavity 6 at the end of the urinary catheter or the pipeline of the urine bag to knead and press to unclog it.

[0040] This device is provided with a liquid pressure sensor 5 inside the water injection pipe 3 for detecting the pressure of the fixed balloon 1, and a liquid level sensor 7 inside the tube body 2 for detecting whether the liquid is flowing, thereby reminding medical personnel that the catheter is blocked. Moreover, when the alarm reminder modules connected to the liquid pressure sensor 5 and the liquid level sensor 7, which are respectively provided in the water injection pipe 3 and the tube body 2, both sound an alarm, it indicates that the first blockage situation has occurred, that is, blockage has occurred inside the catheter, thereby directly reminding medical personnel to take corresponding measures; when only the alarm reminder module connected to the liquid pressure sensor 5 in the water injection pipe 3 sounds an alarm, it indicates that the second blockage situation has occurred, that is, blockage has occurred in the pipeline of the urine bag connected to the catheter, thereby directly reminding medical personnel to take corresponding measures; therefore, this device can remind medical personnel when blockage occurs, and does not require staff to distinguish the blockage situation in advance, which facilitates the unblocking of the catheter and reduces the workload of medical personnel.

[0041] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
