Description

Laminar flow tent for operation Technical Field The invention mainly relates to the technical field of medical equipment, in particular to a laminar flow tent for operation. Background The clean operation tent not only requires highly clean air (the air entering an operation room is firstly purified by a high-efficiency filter), but also requires that the circulation direction of the air flow can be controlled (namely, a laminar flow ultra-clean device is adopted), so that the air flow flows from an operation area with high cleanliness to an area with low cleanliness and takes away and discharges dust particles (dust particles) and bacteria in the air flow, the laminar flow is a fine and thin air flow which is conveyed in the same direction at a uniform flow rate, and the direction of the purified air flow is divided into a vertical laminar flow type and a horizontal laminar flow type. Patent number CN116291002a discloses a device management system for a laminar flow sterile operation tent, the device adopts an inflatable tent, and the inside adopts a vertical laminar flow operation room, to this kind of inflatable tent need to inflate the inflatable column inside before using, the inside in-process of inflation is just continuously getting into outside air to cause the clean degree of air to reduce and bacterial number will promote.
