Insufflation

Hot and cold gas insufflators, separate heating module, heating tubes

Innovation pioneer WISAP

For laparoscopic surgery, a pneumoperitoneum is artificially created to provide the necessary “space” for the operation. Using a Verres needle or trocar, carbon dioxide (CO₂) is introduced into the abdominal cavity for this purpose. The gas pressure in the insufflator is regulated down from 60 bar to the necessary level, which causes the gas to relax and cool down considerably. In the course of an operation, several hundred liters can flow through the patient, resulting in hypothermia. To prevent hypothermia, WISAP equipped its insufflators with gas heaters as early as 1970. Studies have shown that the use of body-warm gas counteracts patient hypothermia. This can reduce the need for painkillers by up to 30% after surgery.

TETRAFLATOR ULTRA-FLOW

50 liters maximum flow rate

Like no other method, the monofilament bivalent system according to Semm allows the acquisition of pressure values relevant for patient safety. By using one and the same orifice, alternating for gas insufflation and measurement of static intra-abdominal pressure, maximum safety is achieved.

HIGH flow rate 5 – 50 l/min
LOW flow rate optionally 1 l/min or 3 l/min
CO₂via bottle or hospital network
Integrated drain valve
Large ACTUAL pressure display

TETRAFLATOR

20, 30 and 40 liters flow rate, smoke evacuation optional

With its new insufflator family, WISAP combines the advantages of two developments in the field of insufflation. The decisive factors are performance (speed of initial insufflation) and patient safety (detection of user errors via pressure measurement). The devices offer significant improvement in both areas. The insufflators are available in 20, 30 and 45 liter versions, together with the options of CO₂gas heating and smoke evacuation.

FLOW-THERME

CO₂gas heating module / for any cold gas insufflator

Pelviscopic measurements have shown that depending on the duration of the surgical procedure and the gas consumption, the intra-abdominal temperature may drop below 32 ° C. Hereby, the patient’s well-being after surgery is lowered and is decisive for a multitude of additional postoperative complaints.

After 3 years of research at the Clinic of Gynecology and Obstetrics of the University of Kiel and at the Clinic of the University of Munich, it was shown that by using body-warm gas, the postoperative use of analgesics was significantly reduced.
