Further, the fluid management host provided in this embodiment is applied to a uterine cavity operation, in particular to a hysteroscope planing operation, and an electric negative pressure suction device is required to suck uterine fluid in a uterine cavity and/or cut pathological tissues such as myomas, polyps and the like. The fluid management host provided by the embodiment realizes the synchronous management effect of suction and fluid flow, thereby saving the operation space and facilitating the quick operation of medical staff.

It should be noted that, in order for the fluid management host in this embodiment to achieve the above functions, referring to fig. 3A and 3B, the fluid management host in this embodiment further includes a power controller 14, where the power controller 14 is electrically connected to the main control board 12;
The power controller 14 may include a power main board 141, a power filter 142, a potential balance connector 143, a power switch 144 and a power interface 145 connected to the power filter 142, where the power filter 142, the potential balance connector 143, the power switch 144 and the power interface 145 are respectively disposed in the host housing 11, and the power interface 145 is used for externally connecting a power supply.
The power supply main board in this embodiment is configured to convert AC220V into DC24V direct current, where the power supply module is connected to a power supply filter, and the power supply filter is connected to an overcurrent protection fuse, and the power supply filter can effectively filter a frequency point of a specific frequency or a frequency other than the frequency point in a power supply line to obtain a power supply signal of the specific frequency, or eliminate a power supply signal after the specific frequency. The potential balance connector is used for grounding protection of the fluid management host, and the embodiment is not particularly limited.
In a specific embodiment, the main control board is specifically configured to generate at least one of the following suction control instructions:
< suction control instruction 1>
And generating a suction control instruction for controlling the start of the suction pump set according to the liquid injection amount and a preset liquid injection amount threshold. The above-mentioned preset threshold value of the infusion amount in this embodiment may be the amount of uterine fluid needed for uterine distension (for example, 800mL of the threshold value may be adjusted according to the distension Gong Daxiao, the operation position and the physical sign of different patients), and when the infusion amount is monitored to be greater than the threshold value, an aspiration control command for starting aspiration may be generated, so as to avoid the risk of surgery caused by excessive infusion of the distension Gong Ye. Of course, in this embodiment, the filling valve of the filling container may be closed, which is not particularly limited in the embodiment of the present invention.
< Suction control instruction 2>
And generating a suction control instruction for controlling the suction pump group to stop according to the liquid outlet amount and the capacity of the liquid collecting container. The capacity of the liquid collection container in the embodiment of the invention is fixed, and when the liquid discharge amount is detected to be close to the capacity, the suction is stopped to avoid overflowing the liquid collection container or avoiding the damage to equipment caused by sucking the bulge Gong Ye to the suction pump set.
< Suction control instruction 3>
And generating a suction control instruction for controlling the suction pump set to stop according to the difference value of the liquid injection amount and the liquid discharge amount. In this embodiment, when the amount of the liquid is too large to satisfy the requirement of uterine distension, the suction needs to be stopped to avoid the influence on the surgical field due to the insufficient uterine distension effect.
< Suction control instruction 4>
And generating a suction control instruction for controlling the suction pump set to stop according to the liquid injection amount, the liquid discharge amount, the preset compensation amount and the preset deficit threshold. In this embodiment, when the deficit is greater than the preset deficit threshold, the patient is likely to cause a series of serious complications or clinical symptoms such as dilutional hyponatremia and water poisoning, and therefore the operation needs to be stopped. But the suction needs to be stopped firstly to stop injection, so as to prevent the intrauterine pressure loss.
< Suction control instruction 5>
And generating a suction control instruction for regulating and controlling the suction power of the suction pump set according to the liquid injection flow rate corresponding to the liquid injection amount and the liquid outlet flow rate corresponding to the liquid outlet amount. In the embodiment of the invention, the peeled and cut tissues are required to be cleaned in time in the operation process, so that the internal expansion Gong Ye of the uterine cavity is ensured to be clear, the influence of turbidity on the operation visual field is avoided, and the uterine expansion liquid is required to be continuously pumped out to achieve the balance effect. According to the monitored liquid injection flow rate corresponding to the liquid injection amount and the liquid outlet flow rate corresponding to the liquid outlet amount, the speed of the liquid injection flow rate and the liquid outlet flow rate can be judged, and at the moment, the suction power of the suction pump set needs to be regulated and controlled so as to achieve the balance of injection and suction.

For example, the preset attractive force is 300mmHg, the measured attractive force of the suction pump set is 400mmHg, the PWM voltage regulation mode can change the voltage by regulating the length of pulse time, the motor power of the suction pump is regulated according to the attractive force difference value between the attractive force measured by the air pressure sensor and the preset value, and the control value of the suction pump is regulated in real time, so that the output power of the motor is stabilized within +/-10% of the preset value of 300mmHg, and the accurate stabilization of the actual attractive force near the preset attractive force is ensured.
It should be noted that, the above-mentioned gas sensor measures the attractive force of the suction pump, and it is understood that the attractive force in the pipeline connected to the suction port of one suction pump is consistent, so in this embodiment, the above-mentioned gas sensor may be located at any position in the pipeline, as long as the measured attractive force can be sent to the main control board, and this embodiment is not particularly limited.

The inventor fully considers the application range of the suction force of the suction pump during hysteroscope operation, and finds that the suction force of the negative pressure of 50-700 mmHg can meet the suction force of medical instruments (shavers) after multiple experiments (the suction force is generally set between 200-400 mmHg in clinical use), but the suction force lower than 120mmHg can meet the suction requirement when fluid overflowed into a buttock collecting device is sucked. The inventors have comprehensively considered the overall cost and the requirements such as the required attractive force limit value, and the like, and in this embodiment, three suction pumps with attractive force of about 400mmHg are used as power sources.

The above data in this embodiment may implement man-machine interaction through a display screen, and further, display the data sent by the main control board and display, for example, display monitoring data such as a real-time deficit value, a real-time attraction value, or dynamic data. Compared with the prior art that the electric aspirator mostly uses a mechanical pointer type to display, the display screen in the embodiment is clearer, more accurate and more stable, and meanwhile, the attractive force is stabilized near the preset attractive force in the operation process, so that the digital display is more intelligent.
