Double Lumen Endobronchial Tube Double Lumen PVC Endobronchial Tube with FDA&ISO Certificate Double Lumen Endobronchial Tube,Disposable Silicone Tube,Dlt Silicone,Pvc Double Lumen Endobronchail Cannula Hangzhou Trifanz Medical Device Co., Ltd , https://www.cfzmeds.com
Made of non-toxic medical-grade PVC, transparent, soft and smooth.
Flat design of balloon section can seal effectively and reduce oppression.
With ventilation transition connector, unilateral ventilation can be more convenient.
Description:
A double-lumen Endotracheal tube is a type of endotracheal tube which is used in tracheal intubation during thoracic surgery and other medical conditions to achieve selective, one-sided ventilation of either the right or the left lung.
There are several conditions that may make one-sided lung ventilation necessary. Absolute indications include separation of the right from the left lung to avoid spillage of blood or pus from an infected or bleeding side to the unaffected side. Relative indications include the collapse of one lung and the selective ventilation of the remaining lung in order to facilitate exposure of the anatomical structures to be operated on in thoracic surgeries.
Construction:
Consist of PVC tube, cuff, inflation lumen.
Those who have purchased high-efficiency coating machines will find a strange phenomenon. The prices of various high-efficiency coating machines on the market are not equal, and the gap is still great. For the cheaper, the purchaser does not dare to buy, worried about the quality of the problem; for the high price, the buyers do not know how to explain to the superior, always will be difficult, do not know how to choose efficient coating machine. In fact, there is something wrong with buying this stuff.
The same type of coated tablets are produced under the same specifications. The high-efficiency coating machines of different manufacturers have different yields of the products due to the different structure of the coating pans (if there are coating machines, there are 1 pot of 10 pots. Rework, some packs of 10 pots have 9 pots to be reworked), the amount of coated powder is very different, and also causes differences in power and labor costs, making the production cost of the product different.
Produce the same kind of shaped coated tablets or printed coated pieces under the same specifications. The high-efficiency coating machine of different manufacturers also wears the surface of the coated tablets due to the different structure of the coating pan and the flap baffle. Different, resulting in the same kind of coating products, some manufacturers of high-efficiency coating machines can not be packaged, and some manufacturers of high-efficiency coating machines can be packaged (such as the FDA-tested erythromycin enteric coated tablets In the case of coating production, the technical details of the high-efficiency coating machine are highly demanding, so that if a product to be coated cannot be coated on the purchased high-efficiency coating machine, the economic loss is even greater.
The same batch of coated tablets are produced under the premise of the same equipment specifications. The high-efficiency coating machines of different manufacturers have different production rates, which makes the labor and power costs required for the same batch of films different, resulting in serious production costs.
When we buy an efficient coater, we should look at the seven basic parameters in addition to what we said above.
1. The position of the spray gun, that is, the position of the atomizing spray gun in the coating drum, generally has two modes, the spray gun is facing the inner and lower direction of the drum or the spray gun is facing a certain position on the inner wall of the drum. In general, this mode is very important for the quality of the final coating of the Zui, while the domestic spray gun is mainly oriented to the lower body of the drum.
2. The spray rate, that is, the amount of atomization, which is the total amount of the coating liquid (suspension) sprayed per unit time.
3. Atomization pressure, which contains two concepts, namely the pressure at which the spray nozzle atomizing gas and the suspension generate mist and the pressure of the atomizing gas itself.
4. The temperature of the air inlet, that is, the temperature of the hot air used to dry the coated tablets in the inlet drum.
5. The total air intake volume, that is, the air volume used for drying and penetrating the sheet bed in the inlet drum, usually adjusts the air volume to be slightly larger than the air inlet volume, so that a slight negative pressure in the coating drum can be caused, so that the coating liquid can be smoothly Enter the sheet bed.
6. The pressure inside the coating drum, the pressure difference between the coating drum and the chamber, the pressure difference is insufficient, the coating liquid can not be sucked into the sheet bed, but adhered to the surface of the sheet bed, the inlet, the inner wall of the drum or the spray system; the pressure difference Excessively high will bring in excess coating liquid into the bed.
7. The rotation speed of the coating drum has a theory that the rotation speed of the coating drum should be set constant according to experience, and how to be discussed.
When purchasing high-efficiency coating machines, you should not only blindly pursue the surface factors such as price, appearance, etc., and must consider all the coating costs incurred by the equipment in the production process of the product coating. When you buy equipment, you need to shop around, taking into account operating costs and prices, in order to purchase the ideal high-efficiency coating machine.
