[The development of a portable life support device for transporting pre-hospital critically ill patients].

OBJECTIVE: To describe a portable life support device for transportation of pre-hospital patients with critical illness. METHODS: The characteristics and requirements for urgent management during transportation of critically ill patients to a hospital were analyzed. With adoption of the original equipment, with the aid of staple of the art soft ware, the overall structure, its installation, fixation, freedom from interference, operational function were studied, and the whole system of life support and resuscitation was designed. RESULTS: The system was composed by different modules, including mechanical ventilation, transfusion, aspiration, critical care, oxygen supply and power supply parts. The system could be fastened quickly to a stretcher to form portable intensive care unit (ICU), and it could be carried by different size vehicles to provide nonstop treatment by using power supply of the vehicle, thus raising the efficiency of urgent care. CONCLUSION: With characteristics of its small size, lightweight and portable, the device is particularly suitable for narrow space and extreme environment.

[The design of stretcher integrated first-aid system].

OBJECTIVE: To satisfy the requirements of pre-hospital and first aid at scene for critical patient, rapid transportation, and nonstop treatment in hospital, this paper describes a design of a stretcher integrated first-aid system (SIFAS), which can provide seamless link between pre-hospital and in-hospital first aid. METHODS: With the requirements of integration and informationization, related functional modules of the former invented SIFAS were redesigned with principle of miniaturization. Adhering to the principle of best man-machine performance, systemic structural characteristic was studied. Aiming at achieving the best maneuverability but with lightest weight, the materials and processing technology of the framework were modified and improved. RESULTS: The SIFAS designed possessed good flexibility, it could be carried on pushed, and it could be attached to many carriers, with shortened time, and continuous first aid could be realized, and waiting time for first aid was greatly reduced. CONCLUSION: The SIFAS provides a possibility for establishing a emergency green path for pre-hospital and in-hospital first aid, and it improves emergency of the patient and quick response of relevant medical institutions.

[Clinical observation on effect of huoxue jieyu decoction in treating depression after craniotomy: a report of 45 cases].

OBJECTIVE: To observe the therapeutic effect of Huoxue Jieyu decoction (HJD) on patients with depression after craniotomy. METHODS: Ninety patients were randomly divided into 2 groups according to the sequence of their consultation. The 45 patients in the treated group were treated with conventional symptomatic treatment plus oral administration of HJD, and the 38 patients in the control group were treated in the same way but with chlorimipramine (anafranil) instead of HJD. Hamilton depression (HAMD) scores before and after treatment, occurrence of adverse effects and long-term therapeutic effect of treatment were observed. RESULTS: The score of HAMD was insignificantly different in 2 groups before and after treatment (P >0.05), but the occurrence of adverse effects between them was significantly different (P < 0.01). CONCLUSION: The therapeutic effect of HJD on depression was similar to that of anafranil, but HJD has less adverse effect and more stabilized long-term effect.
