Description

[Technical field]

[0001] The utility model relates to the technical field of urine catheter bags, in particular to the technical field of quantitative drainage urine catheter bags. [Background technology]

[0002] Catheterization is a technique of inserting a catheter into the bladder through the urethra to drain urine. It is usually used clinically to directly drain uncontaminated urine specimens from the bladder, drain urine for patients with urinary retention, empty the bladder before pelvic organ surgery, and assist recovery after certain urinary system disease surgeries. A catheter bag is a container that can be installed at the other end of a catheter to temporarily store the drained urine, such as a medical urology catheter bag disclosed in the invention with publication number CN112755266A, a urology catheter bag disclosed in the utility model with announcement number CN215460557U, and a catheter bag with a fixing device disclosed in the utility model with announcement number CN211050389U.

[0003] The capacity of a common catheter bag is usually 1000ml. If it is filled with urine but not emptied in time, it will cause urine reflux and increase the chance of infection. When performing catheterization, the amount of urine discharged has different requirements according to different clinical conditions. For example, the first urine discharge for bladder retention should not exceed 1000ml, and the single urine discharge for intermittent catheterization should not exceed 500ml. In addition, for postoperative drainage, if the drainage speed is too fast (more than 300ml per hour), it is necessary to consider whether there is a possibility of bleeding. However, the existing catheter bags cannot automatically monitor the urination situation according to the above situation, resulting in medical staff having to manually check from time to time, which is very troublesome. [Contents of the utility model]

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide a quantitative drainage type urinary catheterization bag, which can realize intelligent urinary catheterization and thus reduce the clinical care pressure of medical staff.

[0005] To achieve the above-mentioned purpose, the utility model proposes a quantitative drainage type urine catheter bag, including a urine storage bag, a manual valve, an extension tube, a plug, a urine volume monitoring mechanism, an electric clamping mechanism and a controller. The manual valve is installed at the urine outlet of the urine storage bag, the plug is indirectly connected to the urine inlet of the urine storage bag through the extension tube, the urine volume monitoring mechanism is installed on the urine storage bag and monitors the urine volume in the bag in real time, the extension tube can be electrically opened or closed by the electric clamping mechanism, and the controller is communicatively connected to the urine volume monitoring mechanism and the electric clamping mechanism respectively.

[0006] Preferably, the urine volume monitoring mechanism includes an internal monitoring permanent magnet, an external monitoring permanent magnet and a liquid level sensor. The internal monitoring permanent magnet and the external monitoring permanent magnet are magnetically attached to the inner and outer sides of the urine storage bag respectively. The liquid level sensor is installed on the internal monitoring permanent magnet. The outer wall of the urine storage bag is provided with scale lines and the top is provided with a feed port, and the feed port is switched by a clamp.

[0007] Preferably, the inner monitoring permanent magnet and the outer monitoring permanent magnet are respectively covered with an inner cover shell and an outer cover shell, and the inner monitoring permanent magnet, the liquid level sensor and the inner cover shell can enter and exit the urine storage bag together along the feed port, and a handle is also provided on the outer cover shell.

[0008] Preferably, the electric clamping mechanism includes a base block, a movable bolt, a clamping permanent magnet and an electromagnet. A through hole is provided on the base block, and the extension tube passes through the base block along the through hole. A blind opening and a through opening are respectively provided in the base block and on opposite sides of the through hole. One end of the movable bolt extends into the through opening and has a built-in clamping permanent magnet. The electromagnet is installed in the base block and arranged close to the blind opening.

[0009] Preferably, a plurality of slide grooves are respectively arranged on the inner wall of the through opening, and a plurality of sliding blocks slidably connected in the slide grooves are respectively arranged on the outer wall of the movable bolt.

[0010] Preferably, the controller is provided with an alarm module and a timing module.

[0011] Beneficial effects of the utility model:

[0012] 1) By adding a urine volume monitoring mechanism on the urine storage bag that can monitor the urine volume in the bag in real time, and installing an electric clamping mechanism on the extension tube between the urine storage bag and the plug, when the urine volume monitoring mechanism detects that the urine temporarily stored in the urine storage bag reaches a specified amount, the electric clamping mechanism can automatically cut off the extension tube to stop catheterization, which can avoid excessive catheterization and prevent urinary tract reflux and infection caused by excessive urine storage in the urine storage bag, thereby reducing the clinical care pressure of medical staff;

[0013] 2) The urine volume monitoring mechanism is formed by using an inner monitoring permanent magnet, an outer monitoring permanent magnet, a liquid level sensor, an inner cover shell, an outer cover shell and a handle, and a feeding port switched by a clamp is added at the top of the urine storage bag. On the one hand, the height of the liquid level sensor inserted into the bag can be accurately adjusted by using the magnetic force between the inner monitoring permanent magnet and the outer monitoring permanent magnet in real time outside the bag, and on the other hand, the urine volume monitoring mechanism can be easily disassembled and used repeatedly;

[0014] 3) The electric clamping mechanism is composed of a base block, a movable bolt, a clamping permanent magnet and an electromagnet, which not only facilitates the magnetic attraction of the movable bolt to move and close the extension tube by pressure, but also makes it very easy to disassemble and assemble;

[0015] 4) By adding an alarm module and a timing module to the controller, the alarm module can be used to promptly notify medical staff by means of an alarm, and the timing module can also be used to achieve the function of timing shutdown and monitoring the maximum discharge volume of urine within a specified time.

The manual valve 2 is installed at the urine outlet of the urine storage bag 1, and the plug 4 is indirectly connected to the urine inlet of the urine storage bag 1 through the extension tube 3. The urine volume monitoring mechanism 5 is installed on the urine storage bag 1 and monitors the urine volume in the bag in real time. The extension tube 3 can be electrically opened or closed by the electric clamping mechanism 6. The controller 7 is respectively connected to the urine volume monitoring mechanism 5 and the electric clamping mechanism 6 for communication.

[0022] The urine volume monitoring mechanism 5 includes an inner monitoring permanent magnet 51, an outer monitoring permanent magnet 52 and a liquid level sensor 53. The inner monitoring permanent magnet 51 and the outer monitoring permanent magnet 52 are magnetically attached to the inner and outer sides of the urine storage bag 1 respectively. The liquid level sensor 53 is installed on the inner monitoring permanent magnet 51. The outer wall of the urine storage bag 1 is provided with scale lines and the top is provided with a feed port, and the feed port is switched by a clamp 8.

[0023] The inner monitoring permanent magnet 51 and the outer monitoring permanent magnet 52 are respectively covered with an inner cover shell 54 and an outer cover shell 55. The inner monitoring permanent magnet 51, the liquid level sensor 53 and the inner cover shell 54 can enter and exit the urine storage bag 1 along the feed port together. A handle 56 is also provided on the outer cover shell 55.

[0024] The electric clamping mechanism 6 includes a base block 61, a movable bolt 62, a clamping permanent magnet 63 and an electromagnet 64. A through hole 611 is provided on the base block 61, and the extension tube 3 passes through the base block 61 along the through hole 611. A blind opening 612 and a through opening 613 are respectively provided in the base block 61 and on the opposite sides of the through hole 611. One end of the movable bolt 62 extends into the through opening 613 and has a built-in clamping permanent magnet 63. The electromagnet 64 is installed in the base block 61 and is arranged close to the blind opening 612.

[0025] A plurality of slide grooves 614 are respectively disposed on the inner wall of the through opening 613 , and a plurality of sliders 621 slidably connected to the slide grooves 614 are respectively disposed on the outer wall of the movable bolt 62 .

[0026] The controller 7 is provided with an alarm module and a timing module. The alarm module can be a voice alarm, a light alarm or a communication mechanism that can transmit an alarm message to a mobile device.

[0027] Working process of this utility model:

[0028] First, the inner monitoring permanent magnet 51, the liquid level sensor 53 and the inner cover shell 54 are sent into the urine storage bag 1 along the feed port, so that the inner monitoring permanent magnet 51 and the outer monitoring permanent magnet 52 are magnetically attached to each other across the urine storage bag, and then the handle 56 is held and the outer monitoring permanent magnet 52 is moved up and down, so that the inner monitoring permanent magnet 51 drives the liquid level sensor 53 to move up and down with it, until the monitoring head of the liquid level sensor 53 is located at the required liquid level (assuming 500ml). Next, the manual valve 2 is used to close the urine outlet, the clamp 8 is used to close the feed port, and the plug 4 is plugged into the catheter. At this time, urine can flow from the bladder into the urine storage bag 1 along the catheter and the extension tube 3 for temporary storage. When the urine in the urine storage bag 1 reaches the specified liquid level (i.e., 500ml), the liquid level sensor 53 will be triggered, so that on the one hand, the electric clamping mechanism 6 automatically closes the extension tube to stop catheterization, and on the other hand, the alarm module automatically alarms to remind medical staff to deal with it as soon as possible. Specifically, the electromagnet 64 can be energized to attract and clamp the permanent magnet 63, so that one section of the extension tube 3 is gradually squeezed into the blind opening 612 by the movable bolt 62 and slowly flattened.

[0029] In addition, the timing operation can be performed through the display screen and the operation panel on the controller 7, such as inputting the urination time as 1 hour, so that the catheterization will automatically stop and an alarm will be sounded after the time is reached. The timing module can also work in conjunction with the urine volume monitoring mechanism 5, such as setting the urination time as 1 hour and the maximum urine volume as 300ml (i.e., moving the liquid level sensor 53 to 300ml), so that the alarm module will automatically alarm when it finds that the urine volume reaches 300ml within 1 hour.

[0030] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
