[0001] The utility model relates to the technical field of medical equipment, in particular to a centralized surgical waste liquid treatment system. Background Art

[0002] The hysteroscopic diagnosis and treatment project is a minimally invasive endoscopic diagnosis and treatment technology for routine gynecological uterine cavity diseases. Because the uterine cavity is normally in a completely closed state, a uterine distension pump is required during the operation to continuously inject uterine distension medium into the uterine cavity to expand the uterine cavity and provide sufficient operating space for the diagnosis and treatment operation.

[0003] China's invention patent application publication number CN115607755 A discloses a hysteroscopic surgery monitoring system and method, which is an injection device for hysteroscopic surgery designed to address the above-mentioned problems. In fact, during surgery, the uterine distention medium will not be absorbed by the human body, and in order to ensure a reliable field of vision in the surgical environment, a suction tube will be used to simultaneously suck out the uterine distention medium. The existing waste liquid suction usually adopts a mobile cart type, and each operating room needs to be equipped with such a waste liquid recovery cart. When the collection bottle in the waste liquid recovery cart is full, it needs to be processed at the surgical waste centralized treatment center. Usually, an operating room needs to have more than 2 waste liquid recovery carts for backup. When the recovery bottle of a waste liquid recovery cart is full during surgery, it is not only necessary to pause for replacement, but also someone needs to recycle the cart after the operation (including cleaning the cart), which increases the postoperative cleaning burden of medical staff. Summary of the invention

[0004] The utility model designs a centralized treatment system for surgical waste fluid, which facilitates uterine distension surgery by using a centralized treatment method instead of traditional cart recovery, and provides intuitive data reference for surgeons through flow meter feedback.

[0005] A surgical waste liquid centralized treatment system, comprising: an MCU, an RJ45 communication module, one end of a waste liquid suction tube being connected to a pre-buried pipeline as an output end;

[0006] Pre-buried pipelines are installed inside the hospital walls;

[0007] A buffer bottle is arranged in the centralized processing center of the operating room, the input end of which is provided with a first control valve, the input end is connected to the pre-buried pipeline, and the output end is connected to the liquid collection bottle;

[0008] The liquid collection bottle is arranged in the centralized processing center of the operating room, and has two input ends and one output end. The first input end is connected to the buffer bottle, the second input end is provided with a second control valve, the second input end is connected to the negative pressure supply system of the hospital, and the output end is provided with a third control valve, and the output end is connected to the medical waste pipeline of the hospital;

[0009] A single buffer bottle and a liquid collection bottle constitute a liquid collection unit, and the operating room centralized processing center is equipped with at least two liquid collection units;

[0010] A liquid level sensor is arranged inside the liquid collecting bottle, and a weighing flow sensor is arranged in the connecting pipeline between the liquid collecting bottle and the buffer bottle.

[0011] The MCU is used to process and convert sensor data into signal data that can be sent by the RJ45 communication module, and the RJ45 communication module communicates with the hospital's surgical system. All surgical waste fluids in the operating room are transported to the operating room centralized processing center through pre-buried pipelines.

[0012] A gas permeable membrane is arranged inside the buffer bottle to separate the buffer bottle into an air cavity and a liquid cavity, wherein the input end and the output end of the buffer bottle are both connected to the liquid cavity; an opening is arranged on the bottle wall of the air cavity for gas release. The air cavity opening is connected to the second input end of the liquid collecting bottle and is controlled by the second control valve.

[0013] This arrangement can ensure that the negative pressure of the air cavity is the same as the negative pressure of the liquid collecting bottle, thereby ensuring that the burden on the breathable membrane is within a reasonable range while the buffer bottle increases the accuracy of the weighing flow sensor during gas filtering and defoaming, thereby extending the working time of the breathable membrane.

[0023] The output end of the first liquid collection unit is directly connected to the liquid collection bottle of the second liquid collection unit, and a fourth control valve is arranged on the connecting pipeline between the first liquid collection unit and the second liquid collection unit;

[0024] A group of liquid collecting units is provided with only one weighing flow sensor, which is arranged on the connecting pipeline between the liquid collecting bottle and the buffer bottle of the first liquid collecting unit.

[0025] Using in series can reduce the use of one buffer bottle, but it also increases the use time of the buffer bottle.

[0026] When used in series, only the first liquid collection unit can be used first. When the liquid level sensor of the first liquid collection unit reaches the trigger liquid level, the following operations are performed simultaneously: the negative pressure input of the first liquid collection unit is turned off, the fourth control valve is opened, and the negative pressure input of the second liquid collection unit is opened. The waste liquid in the first liquid collection unit is directly released into the second liquid collection unit. When the liquid level sensor of the second liquid collection unit reaches the trigger liquid level, all the above steps are reversed, so that the first liquid collection unit continues to work normally, while the second liquid collection unit is responsible for emptying the waste liquid into the medical waste pipeline.

[0027] The beneficial effects of the utility model are: avoiding the use of traditional waste liquid recovery carts directly reduces the postoperative cleaning burden of medical staff; secondly, avoiding the situation where the waste liquid recovery cart is full of waste liquid bottles during surgery, thereby avoiding the situation where the surgery is suspended to replace the waste liquid bottles; at the same time, retaining the characteristic of the waste liquid recovery cart for convenient observation of the discharge of uterine distension medium, the hospital's surgical system can simply and intuitively feedback the discharge volume of the uterine distension medium.
