inflatable laryngeal mask is used for oxygen supply. For example, before intravenous general anesthesia intubation, patients are covered by the mouth and nose with the inflatable laryngeal mask to allow them to inhale high flow of pure oxygen, also known as pre-oxygenation, to increase the oxygen content in the patients' lungs and provide sufficient time for the implementation of general anesthesia. In addition, in short surgeries, oxygen can be administered by a mask to assist spontaneous breathing after intravenous anesthesia. When the patient has breathing difficulties and other emergency situations, the mask can be used to give the patient pressure oxygen, the establishment of temporary artificial respiration pathway, for the patient to save time.

What is an inflatable laryngeal mask

First, it is used for oxygen supply. For example, before the implementation of intravenous general anesthesia intubation, the mask will be used to cover the patient's mouth and nose, so that the patient can inhale high flow of pure oxygen, that is, pre-oxygenation, to increase the oxygen content in the patient's lungs and provide sufficient time for the implementation of general anesthesia intubation.

In addition, in short surgeries, oxygen can be administered by a mask to assist spontaneous breathing after intravenous anesthesia. When the patient has breathing difficulties and other emergency situations, the mask can be used to give the patient pressure oxygen, the establishment of temporary artificial respiration pathway, for the patient to save time.

Second, anesthesia is administered with a mask. When inhaling general anesthesia is required, the mask will be used to cover the mouth and nose of the patient, allowing high concentration of oxygen and anesthesia to enter the body through the patient's breathing, so as to achieve the purpose of anesthesia administration.

The use of inflatable laryngeal masks

inflatable laryngeal mask is used in local anesthesia operations such as frontal and facial surgery, ear surgery, ophthalmology surgery and acromioclavicular joint surgery to solve patients' dyspnea with good effects. It is a supporting part of mechanical respiratory devices used in the treatment of respiratory failure patients and is used for clinical anesthetic respiration.

The brandy process (indeed) equipment works with an axial-flow pump inside the unit that sucks in liquid from below, lifts it through a circulating tube to a vacuum chamber, and uses a dispersive element to disperse it into a film and column of droplets. Yes. After that, it is redistributed by the liquid distributor, and the raw material liquid flows uniformly downward to the film along the evaporation surface. Under vacuum conditions, the liquid of the low volatile heating material is sucked from the top of the vacuum chamber until the liquid condenses in the condenser or on the condensing surface opposite the evaporating surface. It's concentrated by evaporation. The concentrated raw material liquid descends and is sent back to the vacuum chamber by the axial flow pump to evaporate. The concentrate continually refreshes the surface, evaporates and concentrates until a suitable product is obtained. Multi-step molecular distillation has been completed in this device. The device has low cost, less investment, convenient operation and maintenance, and can be widely used in industrial production.

The whole set of molecular brandy distillation equipment mainly includes molecular evaporator, degassing system, supply system, heating system, cooling vacuum system and control system.

The core of molecular brandy distillation equipment is the molecular evaporator. There are three main types.

Flow-film type: Although it is an early type with simple structure, it is rarely used in many countries in the world due to its thick liquid film and low efficiency.

Wipe film type: the formation of liquid film, high separation efficiency, but the structure is more complex than downflow film type;

Centrifugal: centrifugal force film forming, film, evaporation efficiency is high, but the structure is complex, the vacuum seal is difficult, the equipment manufacturing cost is high. In order to improve the separation efficiency, it is usually necessary to adopt multistage series to realize the multistage separation of different materials.

brandy distillation equipment is suitable for the recycling of thin alcohols in pharmaceutical, food, light industry, chemical industry and other industries, as well as the distillation of dissolved coal such as methanol. Depending on the user's requirements, the number of devices can be 30. Dilute the alcohol to a 90-95 concentration, no matter how high the alcohol level is and how much alcohol the product contains. You can increase the recycling rate, but the output will decrease accordingly. Use stainless steel cardboard packaging. The body of the rectifying tower is made of stainless steel to prevent the blockage of iron powder and prolong the service life of the equipment.
