Spring is the season with the highest production of shiitake mushrooms in the north. From April to April, it is the season when bags of mushrooms are used. According to the problems that have occurred in the bagging and sterilizing of shiitake mushrooms in the past, several suggestions have been made for the reference of growers. First, the bag should pay attention to the problem 1, the moisture content of culture materials controlled at 65-70%, the judging criteria to hand-grip training materials into a group, finger joints have water stains overflow but not downstream, after loosening can be scattered. Within this range of humidity, appropriate increase in water content can increase mushroom yield. 2. During the bagging process, special attention should be paid to puncture bagging in culture and be handled in time after discovery. 3, the tightness of the culture material should be appropriate, too fast mycelium growth rate, but not robust, affecting production. Second, the sterilization process should pay attention to the problem 1, each sterilization before careful inspection of sterilization equipment to prevent unnecessary losses. 2, bacteria bag sterilization must reach the required time, and according to the bag of the appropriate extension of the morning and evening. Third, the sterilization tube after cooling should pay attention to the following points: 1, after taking out from the sterilizer, we must promptly check whether the bag damage, found that the damage immediately with a good sticky tape, each bag must be checked Once again. 2, bacteria bags in the handling process to take care to prevent scratching broken bags. 3, after the sterilization bag is best placed directly into the inoculation room (shed), natural cooling, four, bacteria should be noted that the inoculation, inoculation action to be fast and accurate, if the culture material exposed to space over time Long, the chance of bacterial infection becomes larger; 2, when the plastic cloth is lifted to avoid vertical force caused by air flow inside and outside the cartridge, resulting in bacterial infection; 3, increase the amount of seed, the inoculum to plug the species Point and micro convex as degree, so as to prevent the invasion of bacteria; 4, when inoculated, bacteria must be quickly after the alcohol lamp, so as not to burn the mycelium; 5, the inoculation time is best selected in the evening or early morning, because the temperature at this time Lower, the concentration of spores in the air is relatively low; 6, when inoculation, the inoculation room to avoid walking around and talking to each other, so as not to hinder the inoculation effect. 7. The temperature of the culture material in the mushroom can not exceed 28°C.
1000ml Urine Drainage Bag
Specialist devices for patients after surgery. It is a kit set, including two radial connectors (one blue and one white, also them as pagoda connector), one cornical connector (transparent), and three threaded luer locks. Six of them are universally used to slove all the turing connection problems after surgery. Using them, no need worrying about leakage, disconnection, size dismatching and others. For blue pagoda connector, it suits with the tubing diameter more than 16Fr, and the white one are applied with the tubings from 3Fr to 16Fr.
The urine bag set consists of A drainage bag and A suction device. Qhy-a is the single drainage bag, and qhy-b is the drainage bag + suction device. The drainage bag consists of the bag body, catheter, lifting lug, joint, guard cap, drainage port, drainage bottom plug, anti-reflux device, and current limiting clip.The suction device is composed of negative pressure bottle, drainage tube joint, suction tube joint, suction connection pipe, automatic drainage device, drainage port and bag body.Should be sterile.
It is used for the collection of body fluids (blood, gastric juice, etc.), secretions (sputum, flushing fluid, etc.) and human excreta (urine, etc.) in hospital, clinical departments and during surgery or after surgery.
