[0021] The following will be combined with the utility model example in the attached Figures 1-4 The technical scheme in the embodiment of the utility model is described clearly and completely, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment, based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0022] The application discloses an anti-clogging alarm device for a urinary catheter, which comprises a urinary catheter 1 and a urine bag 2.

[0023] The urinary catheter 1 is used as a channel for urine drainage, leads urine in a patient's bladder out to the urine bag 2, maintains the normal function of the patient's urinary system, is a core associated component of the whole device and provides a basis for subsequent urine monitoring. The urine bag 2 is used for collecting the urine drained from the urinary catheter 1, facilitates medical staff to observe the amount, color and property of the urine and assists in judging the physical condition of the patient. The flow sensor 3 is installed at the connection between the urinary catheter 1 and the urine bag 2 and is used for monitoring the urine flow in real time. Under normal circumstances, urine continuously and stably flows into the urine bag, and when the flow abnormally changes, for example, decreases or returns to zero, it can be preliminarily judged that the urinary catheter may be clogged, thereby providing an important basis for timely finding the abnormality of the urinary catheter.

[0024] The pressure monitoring mechanism 4 comprises a first clamping arm 41 and a second clamping arm 42 which are symmetrically arranged, the hinge design of the first clamping arm 41 and the second clamping arm 42 enables the first clamping arm 41 and the second clamping arm 42 to be easily opened and closed, facilitates installation on the outer edge of the urinary catheter 1 and makes the medical staff operate more conveniently, thereby greatly improving the ease of use of the device. The inner edge of a fixed wing 411 of the first clamping arm 41 is designed in a semicircle and is highly matched with the contour of the urinary catheter, tightly adheres to the urinary catheter, provides stable support for the whole pressure monitoring mechanism, effectively prevents the mechanism from being displaced or falling off on the urinary catheter and ensures the accuracy and continuity of pressure monitoring. A clamping groove 412 in the middle of the first clamping arm 41 is adapted to the pressure sensor 43 in shape, can accurately fix the pressure sensor 43 and ensures that the pressure sensor is always in the best detection position during the working process, thereby stably sensing the pressure change outside the urinary catheter.

[0025] The pressure sensor 43 is installed in the middle of the first clamping arm 41 and the second clamping arm 42 and the detection end head is higher than the inner wall of the fixed wing 411, this design enables the pressure sensor to more closely and sensitively capture the pressure change around the urinary catheter, greatly improves the monitoring precision of the clogging condition of the urinary catheter and ensures that the pressure abnormal signal can be detected at the first time when the urinary catheter is clogged.

[0026] The bottom of the first clamping arm 41 and the second clamping arm 42 is fixed with a protective shell 44, and the protective shell 44 is internally fixed with a buzzer 45 and a battery pack 46. The protective shell 44 is fixed at the bottom of the first clamping arm 41 and the second clamping arm 42 and provides omnidirectional physical protection for the buzzer 45 and the battery pack 46 inside. In the actual use process, the medical environment is complex and changeable, the equipment will be subjected to external forces such as collision and extrusion, the protective shell can effectively resist these external forces, avoids damage of the buzzer and the battery pack and ensures that the alarm device can continuously and normally operate.

[0027] The pressure sensor 43, the buzzer 45 and the battery pack 46 are electrically connected, and a complete signal transmission and alarm system is constructed. When the pressure sensor 43 detects the pressure change signal caused by the catheter clamp, the signal can be quickly transmitted to the buzzer 45, and the buzzer immediately emits an alarm sound to remind the patient, family member or medical staff that the catheter is clamped. The battery pack 46 provides stable power support for the pressure sensor 43 and the buzzer 45, so that they can work normally. The independent battery pack power supply mode is adopted, which is free from the constraint of external power supply. Whether in a hospital room, an operating room or during patient transfer, the device can operate normally at any time and anywhere, greatly improving the applicability and flexibility of the device.

[0028] Working principle:

[0029] In use, through the hinged design, medical staff can easily open and close the first clamp arm 41 and the second clamp arm 42, and then install the protection shell 44 and other components on the first clamp arm 41 and the second clamp arm 42. The inner edge of the fixed wing 411 of the first clamp arm 41 is semicircular, closely fits the catheter, and provides stable support for the entire mechanism to ensure the stability of the pressure monitoring process.

[0030] The pressure sensor 43 is installed at the middle part of the first clamp arm 41 and the second clamp arm 42, and the detection end is higher than the inner wall of the fixed wing 411. This design enables the pressure sensor to sensitively perceive the pressure change around the catheter at close range. When the catheter works normally, the pressure is in a stable state, and the pressure sensor has no abnormal signal output. Once the catheter is clamped, the pressure around the catheter will change instantaneously, and the pressure sensor 43 quickly captures this pressure change and converts it into an electrical signal.

[0031] These electrical signals are transmitted to the buzzer 45 which is also electrically connected to the battery pack 46 through the circuit electrically connected to the pressure sensor 43. The battery pack 46 provides stable power for the pressure sensor 43 and the buzzer 45 to ensure the normal operation of signal transmission and alarm function. When the buzzer 45 receives the abnormal electrical signal transmitted by the pressure sensor 43, it immediately emits an alarm sound to timely remind the patient, family member or medical staff that the catheter is clamped, so that measures can be taken to solve the problem and protect the patient's health. At the same time, the protection shell 44 fixed at the bottom of the first clamp arm 41 and the second clamp arm 42 can resist external forces such as collision and extrusion that may occur in the medical environment, protect the internal buzzer 45 and battery pack 46 from damage, and maintain the continuous and stable operation of the alarm device.

[0032] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
