[0001] The utility model relates to the technical field related to alarm devices, and relates to an alarm device and an endoscope cleaning brush device with integrated pressure monitoring and alarm functions, which is particularly suitable for cleaning the forceps channel of endoscopes such as gastroenteroscopes. Background Art

[0002] Before using the endoscope for examination, cleaning the endoscope can remove dirt and residue on the surface of the endoscope and ensure a clear field of view. This helps doctors observe the patient's stomach condition more accurately. The most important cleaning is the first step. Brushing the endoscope channel is an essential step to ensure cleaning quality control and reduce the occurrence of hospital infection incidents.

[0003] Traditional cleaning brushes lack a resistance monitoring mechanism. When there is tissue residue in the forceps channel or the instrument is deformed, the operator cannot sense the abnormal resistance, which can easily lead to: 1. The nylon material of the brush falls off in the forceps channel and becomes a source of bacterial growth; 2. Excessive force causes mechanical damage to the inner wall of the forceps channel; 3. The risk of biofilm formation increases, affecting the sterilization effect. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent endoscope cleaning brush alarm device, which effectively solves the problem of instrument damage caused by improper operation of traditional cleaning brushes through real-time pressure monitoring and threshold alarm mechanism.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-6 The figure shows an alarm device for an endoscope cleaning brush. The device adopts a modular design and mainly includes:

[0034] Sensing module: The high-precision pressure sensor 219 is installed inside the mounting sleeve 218, with a detection range of 0-50kPa; Control module: The main controller 207 is fixed on the round table 203 and uses the STM32F103 chip to realize signal processing;

[0035] Alarm module: including SFM-27 type buzzer alarm 202 and IP65 grade warning light 205;

[0036] Power supply module: LR44 button battery 206 is fixed by compression spring 214.

[0037] The specific structure is as follows: it includes a flexible tube 1, one end of which is connected to an alarm structure 2 and the other end is fixedly mounted with a cleaning brush head 3. The alarm structure 2 includes a housing 201 and a mounting sleeve 218. One end of the flexible tube 1 is fixedly connected to the housing 201, and the other end is fixedly connected to the mounting sleeve 218 via a long thin tube 217. The bottom of the flexible tube 1 is mounted with a main controller 207, the top of which is mounted with a buzzer alarm 202, and the mounting sleeve 218 is installed with a pressure sensor 219. The top of the housing 201 is open and equipped with a cover 204. A button battery 206 is installed in the top of the housing 201. The main controller 207 is electrically connected to the button battery 206, the buzzer alarm 202, and the pressure sensor 219. The long thin tube 217 is embedded with a four-core shielded cable, connecting the mounting sleeve 218 to the housing 201.

[0038] It is worth noting that when the endoscope cleaning brush is in use, the cleaning brush head 3 will enter the endoscope's clamp channel for cleaning. Due to the flexibility of the flexible tube 1, it can bend along the shape of the endoscope's clamp channel without causing damage to the endoscope. During the cleaning process, if the cleaning brush head 3 is stuck or encounters abnormal resistance, the pressure inside the flexible tube 1 will change. The pressure sensor 219 installed inside the mounting sleeve 218 can detect this pressure change. Once the pressure sensor 219 detects that the pressure exceeds a preset threshold, it will send a signal to the main controller 207. The main controller 20 After receiving the signal from the pressure sensor 219, the main controller 207 activates the buzzer alarm 202 and issues an audible alarm. The sound can be transmitted through the opening at the top of the housing 201 to remind the operator of the blockage problem. The real-time resistance monitoring is carried out. When the brush head encounters abnormal resistance in the clamp channel (such as tissue residue, instrument deformation or stenosis), the intelligent alarm system is triggered to prevent the operator from continuing to push hard, reducing the risk of bristle breakage, brush rod deformation or scratching the endoscope clamp channel, and reducing maintenance costs. In addition, the main controller 207 is powered by a button battery 206, ensuring the portability and long-term use of the device.

[0039] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5The cover 204 is truncated cone-shaped, with two symmetrically arranged blocks 221 fixedly connected to the outer wall of the cover 204 near the bottom. The top of the housing 201 is cylindrical, with an annular groove 212 defined near the inner wall. The bottom of the housing 201 is conical, with an annular retaining groove 209 defined near the outer wall. A collar 210 is positioned over the retaining groove 209, which is fixedly connected to the outer wall of the cover 204 via a connecting strip 216. Two symmetrically arranged notches 213 are defined in the top sidewall of the housing 201. The cover 204 is secured by the rotational engagement of the blocks 221 with the annular grooves 212. The indicator needle 220 cooperates with the indicator block 211 to provide a visual reference for alignment. The sealing ring 215 achieves IP54 waterproofing.

[0040] The block 221 matches the notch 213, and the cover sleeve 204 can be engaged on the top of the shell 201. The block 221 is rotated and screwed into any position of the annular groove 212, deviating from the position of its notch 213. Then, the entire cover sleeve 204 cannot be removed from the shell 201, providing convenience for the assembly of the cover sleeve 204, thereby improving the overall assembly efficiency.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 3 A warning light 205 is embedded in the center of the top of the cover 204 and is electrically connected to the main controller 207. When the pressure sensor 219 detects that the pressure exceeds a preset threshold, it sends a signal to the main controller 207, which then illuminates the warning light 205, alerting the operator to timely action and enhancing the brightness of the warning light 205. The pressure sensor 219 is FSS-SMT010WNST (the FSS series is designed specifically for medical equipment, with a corrosion-resistant 316L stainless steel sensor head). The buzzer alarm 202 is SFM-27-I (material: ABS housing + metal diaphragm). The warning light 205 is IP65 rated (material: PC transparent cover + aluminum substrate). The button battery 206 is LR44. The main controller 207 is RC-207. The circuitry involved is controlled by default according to the existing technology.

[0042] See Figure 2 and Figure 3The cover sleeve 204 (transparent PC (for easy observation of the indicator light)) is fixed with a sealing ring 215 on the bottom outer wall. A round platform 203 is installed at the bottom of the shell 201. A wire hole 208 is opened in the center of the round platform 203. The main controller 207 is installed on the top of the round platform 203. A compression spring 214 is fixed on the outer wall of the top of the round platform 203. The button battery 206 is placed on the top of the compression spring 214. The compression spring 214 provides an upward elastic force to the button battery 206, so that the button battery 206 can be firmly installed on the inner top of the shell 201. The design of the round platform 203 not only provides a mounting platform for the main controller 207, but also enhances the stability of the inside of the shell 201 through its structure. The setting of the sealing ring 215 effectively prevents moisture or cleaning fluid from seeping into the gap between the cover sleeve 204 and the shell 201, protecting the internal electronic components from damage and improving the durability and safety of the device.

[0043] See Figure 3 and Figure 5 The cover sleeve 204 is located at the position of the card block 221 and is fixedly connected to an indicator pin 220 on the top. The outer wall of the shell 201 is located at the position of the notch 213 and is fixedly connected to an indicator block 211. The indicator pin 220 cooperates with the indicator block 211. When the card block 221 is subjected to external force and slides along the annular card groove 212 to the position of the notch 213, the indicator pin 220 will point to the indicator block 211, thereby giving an obvious visual indication to inform the operator that the card block 221 has reached the preset position, that is, the cover sleeve 204 has been correctly installed or locked. This design not only improves the convenience of operation, but also enhances the user experience through intuitive visual feedback, ensuring the accuracy of the device.

[0044] See also Figure 1 and Figure 4 The cleaning brush head 3 includes a sleeve 301, which is fixedly mounted on the outer wall of the long thin tube 217. The sleeve 301 is equipped with eight bundles of fine bristles 302 (Φ0.3mm) at the front end and six bundles of coarse bristles 303 (Φ0.6mm) at the rear end. Made of antibacterial nylon (antibacterial rate ≥ 99%), the fine and coarse bristles 302 and 303 are designed to accommodate cleaning needs of lumens of varying sizes. The flexible thin tube 1 is made of medical-grade silicone with a bending radius of ≥ 15mm. The long thin tube 217 is embedded with a four-core shielded cable.

[0045] The fine-bristle rod 302 is soft in texture and can penetrate deep into the fine parts of the lumen, gently removing stains attached to the wall of the tube and avoiding damage to the inner wall of the lumen. The coarse-bristle rod 303 has a stronger cleaning force and is suitable for areas with larger lumens or more stubborn stains, ensuring a more thorough cleaning effect. By combining the use of the fine-bristle rod 302 and the coarse-bristle rod 303, the cleaning brush head 3 not only improves the cleaning efficiency, but also ensures the comprehensiveness and safety of cleaning, meeting the diverse cleaning needs during endoscope cleaning. The fine-bristle rod 302 and the coarse-bristle rod 303 are both made of antibacterial nylon silk material, which has good antibacterial properties and can effectively inhibit the growth of bacteria to prevent secondary pollution during the cleaning process. The antibacterial nylon silk material also has good wear resistance and durability, ensuring the stability and reliability of the cleaning brush head 3 during long-term use and extending the service life of the product.

[0046] Working principle:

[0047] 1. Pressure monitoring stage: The pressure sensor 219 samples at a frequency of 100 Hz and transmits the signal to the main controller 207 via a shielded wire. The signal undergoes three-stage filtering (cutoff frequency 10 Hz) to eliminate operational jitter interference.

[0048] 2. Threshold determination stage: The main controller 207 compares the pressure value with a preset threshold (default 25kPa, adjustable range 10-50kPa) in real time. When the pressure exceeds the threshold for 300ms, it is determined to be a valid abnormal signal.

[0049] 3. Alarm triggering stage: Triggering the sound and light alarm combination - the buzzer alarm emits an 85dB intermittent alarm + the warning light flashes red quickly (4Hz).
