Description

Clinical anesthesia is with supplying medicine device
Technical Field
The invention relates to a medical instrument, in particular to a medicine supply device for clinical anesthesia.
Background
The general anesthesia methods commonly used in clinic include inhalation anesthesia, intravenous anesthesia and compound anesthesia. The general anesthesia can be performed by several steps, such as pre-anesthesia treatment, anesthesia induction, anesthesia maintenance, and anesthesia recovery.
1. Inhalation anesthesia
Inhalation anesthesia refers to a general anesthesia method in which a volatile anesthetic or anesthetic gas is absorbed into blood from an anesthesia machine through a respiratory system to inhibit the central nervous system. The first anesthesia method is used in the history of anesthesia, ether is a widely known inhalation anesthetic, but because of the characteristics of instability, flammability and explosiveness, an electrotome and other equipment are frequently required in a modern operating room, so that ether can cause explosion, and the ether is clinically abandoned at present. Inhalation anesthesia has evolved as the primary method of administering general anesthesia. The inhalation anesthetic is little metabolized and decomposed in vivo, and most of the inhalation anesthetic is discharged from the lung in an original shape, so that the inhalation anesthetic has higher controllability, safety and effectiveness.
Inhalation anesthesia can be classified into an open method, a semi-closed method and a closed method according to a contact manner of respiratory gas and air, a repeated inhalation degree and the presence or absence of a carbon dioxide absorption device. The method is divided into low flow anesthesia, minimum flow anesthesia and closed loop anesthesia according to the fresh air flow.
2. Intravenous anesthesia
Intravenous general anesthesia refers to a method of producing general anesthesia by administering one or more drugs intravenously through blood circulation to the central nervous system. Intravenous anesthesia can be classified into single administration, divided administration and continuous administration, depending on the mode of administration. The use of intravenous general anesthesia has been limited for the first time due to its limitations. However, since the 80 s of the 20 th century, with the continuous improvement of clinical pharmacology research methods, the development of new potent and short-acting intravenous anesthetics and the advent of computerized intravenous automatic drug delivery systems, the intravenous anesthesia was greatly improved and developed.
Intravenous anesthesia can be divided into single infusion, fractionated infusion, continuous infusion and target-controlled infusion (TCI) depending on the mode of administration.
Combination should be emphasized for maintenance of anesthesia. Perfect anesthesia is at least to achieve loss of consciousness, complete analgesia, muscle relaxation and inhibition of autonomic reflex on the premise of ensuring the stability of vital signs of a patient. To achieve these four objectives, it is clear that it is not feasible to use a certain class of narcotics, which requires the use of a combination of narcotics.
3. Compound anesthesia
Currently, several different anesthetic drugs or techniques are used simultaneously or sequentially in clinical anesthesia to achieve a general anesthetic state. The anesthesia method for achieving analgesia, amnesia, muscle relaxation, autonomic reflex inhibition and maintaining vital sign stability by simultaneously or sequentially applying more than two general anesthesia medicines or anesthesia technologies is called as balance anesthesia. The balance anesthesia emphasizes the combined medication, and the combined medication not only can embody the pharmacological action of each kind of medicine to the maximum extent, but also can reduce the dosage and the side effect of each medicine. The method plays an important role in improving the anesthesia quality, ensuring the safety of patients, reducing medical expenses and the like, and is in accordance with the anesthesia concept of Chinese national conditions.
Need carry out pressure control and steady transport to anesthetic gas in anesthesia process, need use different narcotic drugs and other medicines to inject simultaneously in anesthesia process, still need inject the medicine of reviving after the operation is accomplished simultaneously, the volume of injecting simultaneously needs to carry out the accurate of different proportions and injects after diluting, simultaneously can not air enter into the patient when the injection in vivo, but the patient adopts intravenous route in the injection process, and only one injection position, so need guarantee in the injection process that the air can not enter into the patient in vivo.
