Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of drainage alarm devices, specifically relating to a drainage alarm device suitable for continuous bladder irrigation. Background Technology
[0002] Continuous bladder irrigation is a common surgical method used after prostate and bladder surgery to prevent bleeding, blood clots blocking ducts, and bladder spasms. However, abnormalities can occur during continuous bladder irrigation, leading to poor drainage, causing patient discomfort, and even worsening damage to the surgical area. Currently available ordinary drainage devices cannot accurately monitor the drainage rate during the fluid drainage process. When drainage is not smooth (i.e., the drainage rate is less than the irrigation rate), the irrigation volume is greater than the drainage volume, which can lead to bladder overfilling and severe pain for the patient, causing unnecessary suffering. Furthermore, the drainage bag capacity of ordinary drainage devices is generally 1000-1500ml, while the capacity of the irrigation fluid bag used for flushing is generally 3000ml. The irrigation fluid volume is greater than the drainage bag capacity. If the drain outlet of the drainage bag is opened to drain the drainage fluid out of the drainage bag, the probability of retrograde infection will increase due to the drainage bag being in an open state for a long time. If the drain outlet of the drainage bag is closed, it is easy for excessive drainage fluid in the drainage bag to cause problems with the timely drainage of urine and irrigation fluid in the bladder, increasing patient discomfort. In severe cases, it can lead to urine reflux and serious complications. In summary, the shortcomings of ordinary drainage devices currently on the market are that (1) the rate of drainage fluid cannot be observed; and (2) the alarm cannot be triggered in a timely manner, resulting in excessive drainage fluid in the drainage bag, which affects the patient's urine and drainage fluid discharge.

Detailed Implementation
[0024] The present invention will now be further described with reference to the accompanying drawings.
[0025] A drainage alarm device suitable for continuous bladder irrigation includes a connecting tube 1 for connecting to a urinary catheter, a drainage bag 2 for containing drainage fluid, and an alarm device 3 for alarming. The drainage bag 2 is connected to the urinary catheter through the connecting tube 1. Drainage fluid or the patient's urine is collected through the drainage bag 2. The alarm device 3 alarms according to the weight of the drainage bag 2, thereby facilitating timely drainage of the liquid in the drainage bag 2 by medical staff.
[0026] The connecting tube 1 has a connector 1-2 and a connector sleeve 1-3 at each end. The connector 1-2 is used to connect to the urinary catheter, and the connector sleeve 1-3 is used to connect to the drainage bag 2. An observation dropper 1-1 is located in the middle of the connecting tube 1. The observation dropper 1-1 is a Mofe's dropper, allowing medical staff to observe the drip rate in the observation dropper 1-1 and compare it with the drip rate of the Mofe's dropper in the flushing infusion set, ensuring that the drip rates are basically consistent and preventing the flushing fluid from being introduced too quickly or too slowly. A clamp switch 8 is provided on the connecting tube 1 to control the on / off state of the connecting tube 1.
[0027] The drainage bag 2 is equipped with a hanging ring 2-3 for hanging the drainage bag 2 on the alarm device 3. The upper and lower ends of the drainage bag 2 are respectively equipped with a connector 2-2 and a drain head 2-1. The connector 2-2 is inserted into the plug sleeve 1-3, and the drain head 2-1 is used to drain the liquid in the drainage bag 2.
[0028] The alarm device 3 includes a weighing sliding assembly 4, an alarm 5, a trigger 6, and a housing 7. The weighing sliding assembly 4 is slidably installed inside the housing 7 and is adapted to the trigger 6. The alarm 5 is fixed inside the housing 7, and the trigger 6 is connected to the alarm 5. The weighing sliding assembly 4 slides according to the weight of the drainage bag 2. When the weighing sliding assembly 4 comes into contact with the trigger 6, the alarm 5 is triggered. To make this device applicable to drainage bags 2 of different capacities, the trigger 6 is adjustablely installed inside the housing 7. By adjusting the relative position of the trigger 6 and the housing 7, the amount of sliding required for the connection between the weighing sliding assembly 4 and the trigger 6 is adjusted. That is, a larger capacity drainage bag 2 can drive the weighing sliding assembly 4 to move a larger amount, and the distance between the trigger 6 and the weighing sliding assembly 4 is larger; a smaller capacity drainage bag 2 can drive the weighing sliding assembly 4 to move a smaller amount, and the distance between the trigger 6 and the weighing sliding assembly 4 is smaller.
[0029] The trigger 6 includes an adjustable plate 6-1 installed in the housing 7 and a battery 6-2 that powers the alarm 5. The adjustable plate 6-1 is provided with a connecting piece 6-3 and a trigger head 6-4 that are respectively connected to the battery 6-2 by a flexible wire.

[0030] The housing 7 is provided with an adjustment groove 7-3, and the adjustment plate 6-1 is provided with a locking pin 6-5. The locking pin 6-5 is slidably installed in the adjustment groove 7-3. The relative position of the locking pin 6-5 and the adjustment groove 7-3 is adjusted to adjust the relative position of the trigger 6 and the housing 7, thereby changing the amount of movement of the weighing sliding assembly 4 required for the connection of the weighing sliding assembly 4 and the trigger 6. A locking nut 6-6 is provided on the locking pin 6-5 to lock the relative position of the locking pin 6-5.
[0031] The weighing sliding assembly 4 includes a weighing guide plate 4-1, a weighing spring 4-2, and a hook 4-3. The weighing guide plate 4-1 is slidably installed inside the housing 7. The two ends of the weighing spring 4-2 are connected to the weighing guide plate 4-1 and the housing 7, respectively. The hook 4-3 is located at the bottom of the weighing guide plate 4-1 and extends outward from the outside of the housing 7. The drainage bag 2 is hooked onto the hook 4-3. During the use of the alarm device, the extension of the weighing spring 4-3 changes with the weight of the drainage bag 2. The weighing guide plate 4-1 moves downward as the weighing spring 4-3 extends, connecting the weighing guide plate 4-1 with the trigger 6. At this time, the alarm 5 is triggered.
[0032] The inner wall of the housing 7 is provided with a first guide groove 7-7 and a second guide groove 7-8. A first conductive sheet 7-1 and a second conductive sheet 7-2 are respectively provided in the first guide groove 7-7 and the second guide groove 7-8. The first conductive sheet 7-1 and the second conductive sheet 7-2 are respectively connected to the alarm 5. The weighing sliding assembly 4 is slidably connected to the first conductive sheet 7-1, and the trigger 6 is slidably connected to the second conductive sheet 7-2. A partition plate 7-4 is provided in the middle of the housing 7, and a sliding groove 7-5 is provided on the partition plate 7-4. The two sides of the weighing guide plate 4-1 are slidably connected to the first guide groove 7-7 and the sliding groove 7-5 respectively, providing guidance for the movement of the weighing guide plate 4-1. The two ends of the adjusting plate 6-1 are slidably connected to the second guide groove 7-8 and the sliding groove 7-5 respectively, providing guidance for the adjustment of the adjusting plate 6-1. Preferably, one side of the weighing guide plate 4-1 extends to the top of the trigger head 6-4. When the weighing guide plate 4-1 abuts against the trigger head 6-4, the alarm 5 is triggered.
[0033] The connecting piece 6-3 on the adjusting plate 6-1 is slidably connected to the second conductive piece 7-2. During the adjustment and sliding process of the adjusting plate 6-1, the connecting piece 6-3 and the second conductive piece 7-2 are always electrically connected. A third conductive piece 4-4 adapted to the trigger 6 is provided on the weighing guide plate 4-1. One end of the third conductive piece 4-4 is slidably connected to the first conductive piece 7-1.
