Purpose of the Device
Intended Use The device is an irrigation pump with a balancing system for hysteroscopies. It is used to introduce fluids into the cavum uteri. The device may not be used for any other endoscopic surgical procedures. The stand and balancing system may only be used with the accompanying pump.
cosity fluid (e.g. Hyskon) is used, the use of more than 500 ml should be followed with great care. See labeling for Hyskon for additional information.
Indication for Use The Hysteroscopy Fluid Management System is indicated for liquid distension of the uterus for diagnostic and operative hysteroscopic procedures, and monitoring the volume differential between the irrigation fluid flowing into and out of the uterus. See the operators manual of your hysteroscope for specific indications for use.
Intrauterine pressure should be maintained as low as possible so as to allow adequate distension and minimize the forces potentially driving fluid, room air and/or gas into circulation.
Contraindications Use of this device for intrauterine distension is contraindicated whenever hysteroscopy is contraindicated. See the operators manual of your hysteroscope for absolute and relative contraindications. Relative contraindications to endometrial ablation: Surgical skill („Acute Technical“). Hysteroscopic endometrial ablation, whether by laser or electrosurgery, should not be undertaken before adequate training, preceptorship, and clinical experience. Additionally, tissue sampling is required prior to destruction of the endometrium. The following are clinical conditions that can significantly complicate hysteroscopic endometrial ablation: • Adenomatous endometrial hyperplasia • Uterine leiomyoma • Severe adenomyosis • Pelvic pain (subtle PID) • Uterine anomalies Relative contraindications to hysteroscopic myomectomy: • Surgical skill (see above) • Severe anemia • Inability to circumnavigate the myoma (re: myoma size) predominantly intramural myomas with small submucous components. Technical Device Application Scope The nominal pressure can be set in the range of 15-150 mm Hg. The nominal flow can be set to 150-500 ml/min. Pressure Readings and Controls This device features non-contact pressure readings of the irrigation medium. The non-contact pressure reading is taken by integrating the pressure chamber into the tube system. The pressure chamber transfers the tube pressure to the device’s processing unit via two pressure sensors. The pressure control circuit continuously compares the actual pressure with the nominal pressure. The function of the device is to maintain the nominal pressure. If the nominal flow is set too low, the nominal pressure cannot be reached. Watch for possible leaks.

Device-Inherent Dangers DANGER
The volume of the irrigation fluid entering and leaving the patient has to be strictly monitored. If a low viscosity liquid distension medium is used, intrauterine instillation exceeding 2 liters should be followed with great care due to the possibility of fluid overload. If a high vis-
EN-4
DANGER
DANGER Intrauterine distension can usually be accomplished with pressures in the range of 35-75 mm Hg. Unless the systemic blood pressure is excessive, it is seldom necessary to use pressure greater than 75-80 mm Hg. DANGER In accorddance with its design purpose, the pump may be used without a balancing system exclusively for diagnostic purposes. Pay attention to the indications for the pump unit in the separate handbook. DANGER Fluid overload (Hypotone Hyperhydratation) By passing through the uterus, irrigation fluids could end up in the blood system or in the patient’s tissue. This could happen in the cases of overpressure, a lengthy operation, or a perforation of the cavum uteri. The resulting disruption of the electrolyte balance could cause the TUR syndrome. The doctor bears responsibility for the monitoring and assessment of the mentioned factors. DANGER It is up to the physician in charge if and when to use the instrument detection process. The irrigation pressure is displayed if the instrument detection function is not performed or the STOP key is pressed during operation. The status of the instrument detection function cannot be displayed or loaded during surgery. DANGER The instrument recognition may only be performed outside of the patient and at a height of +/- 10 cm to the height of the uterus (operation’s height). DANGER Stop the device using the Start/Stop key if instrument is changed during surgery. DANGER Follow the instructions and sequence to perform the instrument detection exactly to avoid the display of incorrect actual pressure values.
2
Purpose of the Device
DANGER Distension could be lost with cancellation of the high-flow or high-pressure settings. DANGER This device is intended only for use with flexible fluid containers. Glass containers might break. Fluid cannot flow quickly enough due to the vacuum being generated inside of the bottle. Risk of implosion. DANGER Air Embolisms An air embolism can be the result of air contained in the tube set or connected instrument reaching the patient. Make sure that there is always fluid in the bag to prevent air from being suctioned into the patient. DANGER Setup the device in such a way as to allow for easy monitoring of the display values, device functions, and access to the control elements.
2
Purpose of the Device
DANGER Quantity of fluids/Concentration of sodium It is necessary to monitor the amount of fluids left in the patient and the concentration of sodium in the blood serum. The total amount of fluids that the device has lost is the deficit amount. Take notice of the measurement tolerance of the system. The calculation of the amount of fluids that is left in the patient lies under the doctor’s judgment and responsibility. DANGER Filling of the tubing and resetting the display are to be done at doctor’s discretion. When using the balancing system follow the exact operating instructions in this handbook. Should the pump be used without the balancing unit for diagnostic purposes, the corresponding handbook is to be consulted without fail. DANGER With a power outage the deficit and inflow values will be lost.
WARNING Endoscope The device may only be connected to endoscopes designed for use with the device for the intended medical procedure. The endoscopes must comply with the most recent versions of EN 60601-2-18 and ISO 8600. DANGER The usage of bags or containers not approved for the device, or large and/or lopsided loads, could cause the device to tip over. DANGER Balancing error The complete system is composed of the weighing system and the stand system, each of which include their own components. The individual components may not touch one another, in order not to compromise exactness of measurement. Please pay attention that the bag, tubes, container, equipotential cable and other parts of the weighing system do not come into contact with the pump unit, the carrier plate, the unit-carrying frame and the roller base. Pay attention that the load controller and its O-ring do not touch the scale pole. The secretion containers must hang freely and may not be damaged in any way. DANGER Make sure that neither the mains cable nor the equipotential cable touch the scale system. The device may only be operated with angular equipotential MC plugs.
DANGER Please pay attention that the containers hang freely and are not supported or in contact with anything from below, otherwise the weight necessary for balancing cannot be accurately ascertained. DANGER Operation of the device is prohibited should you suspect an instrument error, or when you determine through the performance test that there is an error. Operation of the device is also prohibited with obvious defects, especially at the mains connection or mains cable. DANGER Electromagnetic Interference Electromagnetic interference with other devices or instruments was practically eliminated when developing this devices and none was detected during testing. However, if you still detect or suspect such interference, please follow these suggestions: • move this device to a different location, • move the other device, • increase distance between all used devices, • consult an electromedicine expert.
