Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a urinary catheter that facilitates the replacement of anti-reflux bags. Background Technology

[0002] When a patient is unable to urinate normally or is temporarily unsuitable for voluntary urination due to various reasons, a urinary catheter can be used to drain urine. When using a urinary catheter, it needs to be used in conjunction with a urine bag. To prevent backflow of urine from the urine bag, the urine bag is connected to the catheter via an anti-reflux tube. However, the replacement times for the anti-reflux tube and the catheter differ, necessitating separation. Current methods connect the anti-reflux tube and the catheter by inserting a rubber tube directly, which makes it inconvenient for medical staff to remove the rubber tube. They often have to rub the rubber tube back and forth to remove it, which is quite cumbersome. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of the prior art and provide a urine catheter that is easy to replace with an anti-reflux bag. By using the fixing block and connecting block of the disassembly component, the anti-reflux tube and the urine catheter can be easily separated, so that medical staff do not need to rub the rubber tube back and forth.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a urine catheter that facilitates the replacement of an anti-reflux bag, comprising: a urine catheter, a urine bag disposed at the bottom of the urine catheter, an anti-reflux tube disposed between the urine bag and the urine catheter, the bottom of the anti-reflux tube extending into the interior of the urine bag, a disassembly assembly disposed between the urine catheter and the anti-reflux tube for convenient disassembly of the anti-reflux tube, and a sensing assembly disposed at the bottom of the urine bag for sensing the weight of the urine bag.

[0005] Furthermore, the disassembly assembly includes: a fixing block connected to the top of the anti-reflux tube, a connecting block connected to the bottom of the urinary catheter, a single threaded ring connected to the top of the fixing block, and a connecting hole opened at the bottom of the connecting block, the inner wall of the connecting hole being provided with threads.

[0006] Furthermore, the sensing component includes: a protective sleeve disposed at the bottom of the urine bag, the urine bag being located inside the protective sleeve, a pressure sensor being installed at the inner bottom end of the protective sleeve, and a battery slot being formed at the bottom of the protective sleeve, with a button battery installed inside the battery slot.

[0007] Furthermore, the top of the anti-reflux tube is connected to the fixing block, and the bottom of the urinary catheter is connected to the connecting hole.

[0008] Furthermore, the urine bag is provided with a drain tube at the bottom, the protective sleeve is connected to a drain pipe at the bottom, and the bottom end of the drain tube extends into the drain pipe.

[0009] Furthermore, a copper sheet is installed inside the battery compartment, and a protective plate is installed inside the battery compartment.

[0010] Furthermore, a liquid level sensor is installed inside the urine bag.

[0011] This invention provides a urine catheter that facilitates the replacement of anti-reflux bags, and has the following beneficial effects:

[0012] The advantage of this utility model is that by disassembling the fixing block and connecting block of the component, the anti-reflux tube and the urinary catheter can be easily separated, so that medical staff do not need to rub the rubber tube back and forth, thereby reducing the workload of medical staff.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] This application provides a urine catheter that facilitates the replacement of anti-reflux bags. This easy-to-replace urine catheter, through the fixing block and connecting block set in the disassembly component, allows for convenient separation of the anti-reflux tube and the urine catheter, eliminating the need for medical staff to repeatedly rub the rubber tube, thus reducing their workload. Furthermore, the pressure sensor and liquid level sensor set in the sensing component can detect the urine in the urine bag. When there is excessive urine in the urine bag, a signal can be transmitted to the ward call system, allowing medical staff or family members to promptly clean the urine from the urine bag.

[0024] The following provides a detailed description of the urinary catheter that facilitates the replacement of the anti-reflux bag. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] This application will now be described in detail with reference to the accompanying drawings and specific embodiments. Please refer to... Figure 1-7 In this embodiment, a urine catheter that facilitates the replacement of an anti-reflux bag is provided, comprising: a urine catheter 1, a urine bag 2 disposed at the bottom of the urine catheter 1, an anti-reflux tube 201 disposed between the urine bag 2 and the urine catheter 1, the bottom of the anti-reflux tube 201 extending into the interior of the urine bag 2, a disassembly component disposed between the urine catheter 1 and the anti-reflux tube 201 for convenient disassembly of the anti-reflux tube 201, and a sensing component disposed at the bottom of the urine bag 2 for sensing the weight of the urine bag 2.

[0026] Example 1

[0027] The disassembly assembly includes: a fixing block 202 connected to the top of the anti-reflux tube 201, a connecting block 203 connected to the bottom of the urinary catheter 1, a single threaded ring 204 connected to the top of the fixing block 202, and a connecting hole 205 opened at the bottom of the connecting block 203, with threads provided on the inner wall of the connecting hole 205.

[0028] To replace the anti-reflux tube 201, rotate the anti-reflux tube 201. As it rotates, the fixing block 202 will also rotate, causing the single-threaded ring 204 to begin rotating. Because the single-threaded ring 204 has a single thread, it only needs to rotate one full turn to gradually move away from the connection hole 205, thus facilitating the replacement of the anti-reflux tube 201 by medical personnel. To install a new anti-reflux tube 201, align the single-threaded ring 204 with the connection hole 205. After alignment, insert the single-threaded ring 204 into the connection hole 205. Once the single-threaded ring 204 contacts the connection hole 205, rotate it to allow it to enter the connection hole 205, completing the installation of the anti-reflux tube 201.

[0029] Example 2

[0030] The sensing components include: a protective sleeve 3 located at the bottom of the urine bag 2, the urine bag 2 being located inside the protective sleeve 3, a pressure sensor 301 installed at the inner bottom end of the protective sleeve 3, a battery compartment 302 located at the bottom of the protective sleeve 3, a button battery 303 installed inside the battery compartment 302, a copper sheet installed inside the battery compartment 302, a protective plate installed inside the battery compartment 302, a liquid level sensor 208 installed inside the urine bag 2, a power cord installed inside the battery compartment 302, the button battery 303 being electrically connected to the liquid level sensor 208 and the pressure sensor 301 through the copper sheet and the power cord, and the signal output terminals of the liquid level sensor 208 and the pressure sensor 301 being connected to the signal receiving terminal of the patient call system.

[0031] After activation, the liquid level sensor 208 can detect the liquid level in the urine bag 2. When the urine level is too high, the liquid level sensor 208 will detect it and then transmit the data to the signal receiver of the ward call system through the signal output terminal to notify the medical staff. The pressure sensor 301 can sense the weight of the urine bag 2. When the weight of the urine bag 2 is too heavy, the pressure sensor 301 will detect it and then transmit the data to the signal receiver of the ward call system through the signal output terminal to inform the medical staff. This serves to monitor the liquid level and weight of the urine bag 2.

[0032] The liquid level sensor 208 consists of a capacitance measurement chip, a control chip, an operational amplifier unit, and an RS232 unit. The models of the capacitance measurement chip, control chip, and operational amplifier unit can be: PCAP01AD / QFN32, PIC16F18346, and LM2904. Its working principle is as follows: The liquid level sensor 208 is a common sensor for measuring liquid level. It converts the liquid level height into an electrical signal for output. Generally, the specific gravity of the magnetic float is less than 0.5, allowing it to float on the liquid surface and move up and down along the measuring conduit. The conduit contains a measuring element, which can... The liquid level sensor 208 is a mature and conventional technology in this field. Under the action of an external magnetic field, the measured liquid level signal is converted into a resistance signal proportional to the liquid level change, and the electronic unit converts it into a 4-20mA or other e-commerce standard signal output. The liquid level sensor 208 does not improve the circuit or program of the liquid level sensor 208. The circuit connection between the liquid level sensor 208 and the button battery 303, as well as the signal connection between the signal output terminal of the liquid level sensor 208 and the signal receiving terminal of the ward call system, are also common conventional technologies. Therefore, its circuit and signal connection relationship will not be described in detail.

[0033] The pressure sensor 301 is specifically model HM10. Its working principle is as follows: the pressure sensor 301 can sense pressure signals and convert them into usable output electrical signals according to certain rules. The pressure sensor 301 is a mature and conventional technology in this field. This solution does not improve the circuit or program of the pressure sensor 301. The circuit connection between the pressure sensor 301 and the button battery 303, as well as the signal connection between the signal output terminal of the pressure sensor 301 and the signal receiving terminal of the ward call system, are also common and conventional technologies. Therefore, its circuit and signal connection relationship will not be described in detail.

[0034] Example 3

[0035] The top of the anti-reflux tube 201 is connected to the fixing block 202, the bottom of the urine tube 1 is connected to the connecting hole 205, the bottom of the urine bag 2 is provided with an excretion tube 206, the bottom of the protective sleeve 3 is connected to an excretion tube 207, and the bottom end of the excretion tube 206 extends into the interior of the excretion tube 207.

[0036] After urine enters the anti-reflux tube 201 from the urinary catheter 1, it will flow into the urine bag 2 along the anti-reflux tube 201. When the urine in the urine bag 2 needs to be discharged, it can be discharged into the drain tube 207 through the drain tube 206, and then discharged to the outside through the drain tube 207, thereby treating the urine in the urine bag 2.

[0037] The specific workflow is as follows:

[0038] After urine enters the anti-reflux tube 201 from the urinary catheter 1, it flows into the urine bag 2. To drain the urine from the urine bag 2, it can be drained through the drain tube 206 into the drain tube 207, and then discharged to the outside through the drain tube 207. This process handles the urine in the urine bag 2. After activation, the liquid level sensor 208 can detect the liquid level in the urine bag 2. When the liquid level is too high, the liquid level sensor 208 will detect it and then transmit a signal to the ward call system to notify medical staff. The pressure sensor 301 can sense the weight of the urine bag 2. When the weight of the urine bag 2 is too heavy, the pressure sensor 301 will detect it and then transmit a signal to the ward call system to inform medical staff. This process monitors the liquid level and weight of the urine bag 2.

[0039] To replace the anti-reflux tube 201, rotate the anti-reflux tube 201. As it rotates, the fixing block 202 will also rotate, causing the single threaded ring 204 to begin rotating. This allows the single threaded ring 204 to gradually move away from the connection hole 205, facilitating replacement by medical personnel. To install a new anti-reflux tube 201, align the single threaded ring 204 with the connection hole 205. After alignment, insert the single threaded ring 204 into the connection hole 205. Once the single threaded ring 204 contacts the connection hole 205, rotate it to allow it to enter the connection hole 205, completing the installation of the anti-reflux tube 201.
