The invention provides a prediction method and prediction system of an irresponsive gamma globulin Kawasaki disease. The method comprises the following steps that 21 original parameters of SVM model building are collected; the modelling original parameters comprise gender, age, fever time during treatment, clinical classification, CRP detection value, WBC value, PLT value, Hb value, ALT value, AST value, ALB value, gamma globulin using time and clinical diagnosed symptom indicators; the clinical diagnosed symptom indicators comprise conjunctival injection, erythra, cracked lips, a strawberry-like tongue, lymphadenectasis of a neck, hard and swollen hands and feet, digit peeling, crissum peeling and a red and swollen bacillus calmette-guerin scar; discretization is conducted on the original parameters to obtain SVM characteristic values corresponding to the original parameters; the SVM characteristic values are regarded as base data, a SVM model is built, and through the SVM model, a complication with irresponsive gamma globulin of the Kawasaki disease is predicted. By means of the prediction method and prediction system, early intervening treatment can be conducted on a patient, recovery of damage to a coronary artery is promoted, and the prediction method and prediction system have important significance and value on diagnosis and treatment of the Kawasaki disease in the future.

The invention discloses a drilling liner hanger releasing device and method adopting cable tie trigger communication control. The drilling liner hanger releasing control method comprises the steps that a, the upper end of the drilling liner hanger releasing device is connected with a drill rod, the lower end of the drilling liner hanger releasing device is connected with a lifting sub, and the lifting sub is connected with a drilling liner hanger; b, connected pipe strings in the step a are downwards put into a drill well, when the drilling liner hanger is located on an operation position, a cable is downwards put from a wellhead, the lowermost end of the cable is provided with a downhole trigger, the downhole trigger is in a starting state before being downwards put into the well, the downhole trigger is sent to the same well-depth position as the automatic releasing device, and resistance wires are arranged in the downhole trigger to generate heat continuously; and c, a temperature sensor is arranged in the drilling liner hanger releasing device, and when the temperature monitored by the temperature sensor exceeds the temperature threshold value set in advance, the drilling linerhanger releasing device conducts releasing. By adopting the drilling liner hanger releasing device and method, the problems that the drill rod is too long, consequently torque transmitting is not inplace, and a downhole thread cannot be completely loosened can be avoided.

The invention discloses a self-heating temperature control steam hot compressing blinder. The blinder comprises two eye compressing parts arranged at left and right, and the two eye compressing partsrespectively correspond to the left and right eyes; each eye compressing part comprises a self-heating body and an air-permeable membrane, and the self-heating body can generate heat and release vapor; the air-permeable membrane can make the vapor released by the self-heating body pass through; the two eye compressing parts are wrapped with passive temperature control layers; the passive temperature control layers are wrapped with air-permeable bags; holes used for increasing air permeability are formed in the air-permeable bags. Tiny holes are punched in the surface that the membrane is not permeable to increase the air permeability; the formula is innovated, iron powder proportion is reduced, carbon powder proportion is improved, and the proportion structure is adjusted; the blinder heats for 40-50 minutes at a temperature of 42 DEG C, and the use is more comfortable.

The invention provides a liquid reservoir comprising an air inlet tube, an air outlet tube, and a cylinder body, the cylinder body is provided with weld pores, and the weld pores are connected with the air inlet tube and the air outlet tube by electric resistance welding. The invention also provides an air-conditioner comprising the above liquid reservoir. In the embodiment of the invention, a manufacture method of the air-conditioning liquid reservoir is also provided, which is implemented by welding the air inlet tube and the upper cylinder body by electric resistance welding; welding the air outlet tube and the lower cylinder body by electric resistance welding; and welding the upper cylinder body and the lower cylinder body by carbon-dioxide shielded welding or argon-arc welding. The invention overcomes the problem that the copper plating layer of the air inlet tube and the air outlet tube of an existing liquid reservoir is easy to destroy by high temperature and to generate shedding and bubbling on the surface of the plating layer so as to affect the welding effect, thus the invention can achieve good welding effect and low cost.
