Preventive measures: 1, although the formation of various types of deformed fruit is slightly different, but the common feature is in the flower bud differentiation period or female flower development period is subjected to low temperatures, easy to form deformed flowers and develop into a deformed fruit. If malformed melons are found in the early stages, if the outside temperature is low, do not rush to remove them. Temporarily retain the first and second female flowers. When the third female flower appears, the outside temperature will rise. Then remove the first and the second. Two female flowers. The third female flower preserved is generally able to grow normally. 2. Flowering and sapling stage encounters high temperature and drought, pollen germination rate is reduced, resulting in poor fertilization and fertilization, insufficient fertilizer or water during fruit expansion, or partial application of nitrogen fertilizer, imbalance of nitrogen, phosphorus and potassium in soil; Affecting the supply of assimilation materials to fruit; artificial pollination technology errors, biased pollination; pests and diseases, especially virus disease hazards, can all lead to the formation of malformed fruit, should be specific to the situation, in the flowering fruit setting period, control the growth In order to prevent leggy, avoid sitting in high-spot melons, conduct artificial pollination, strengthen field management, and provide balanced cultivation of water and other measures to prevent the formation of malformed melons.

Double Lumen Endobronchial Tube

Double Lumen PVC Endobronchial Tube with FDA&ISO Certificate
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.
