Description
Technical Field
The invention relates to the technical field of operating tables, in particular to an anesthetic dosing operating table.
Background
The operating table is a basic medical appliance product and plays a very important role in surgical and medical operations, and most operations on the operating table require a patient to be performed under anesthesia. General anesthesia is usually selected during anesthesia, and is characterized in that all functions of a patient are temporarily inhibited by using various anesthetics during an operation, so that the mind, pain sensation and muscle of the patient disappear.
General anesthesia generally comprises three stages in the whole operation process, and the anesthesia medication of the three stages is also different: and (3) during the anesthesia induction period: an anesthesiologist can fully master personal conditions such as height, weight and basic medical history of a patient before an operation, the dosage of an anesthesia inducer is calculated, the patient basically reaches states of mental disappearance, pain sense disappearance and muscle relaxation after a few minutes after administration, and the anesthesiologist can indicate a surgeon and start the operation after operations such as tracheal intubation, anesthesia parameter adjustment and the like; and (3) during the anesthesia maintenance period: only the amount of anesthetic capable of enabling the operation to be carried out is given in the induction period, the operation condition cannot be accurately predicted due to comprehensive factors such as operation types, difficulty and the like, the dose may not be enough to maintain the whole operation process, and at the moment, the maintenance dose needs to be supplemented, so that the vital signs of a patient are basically kept stable, and the operation can be smoothly carried out; and (3) during the anesthesia recovery period: when the operation is finished, the anesthetist can make various anesthetics lose efficacy at the same time as much as possible, but because the continuous acting time of various anesthetics in the human body is different, the anesthetist needs to stop the medicines in advance according to the operation process so as to achieve the purpose that the patient can be stably recovered when the operation is finished.
In the prior art, anesthetic gas is usually mixed into an oxygen tube to be directly inhaled by a patient, but in practical application, the method has certain defects, such as:
1. the anesthetic gas is not convenient to be quantitatively supplemented, and the condition of too much or too little anesthetic gas often occurs;
2. the anesthetic gas is directly mixed into the oxygen tube, the mixture of the anesthetic gas and the oxygen is not uniform enough, and when the anesthetic gas acts on the body of a patient, instantaneous deviation can be generated, so that the effect of the anesthetic gas is influenced;
3. the anesthetic gas is directly mixed into the oxygen tube, and the concentration of the mixed gas of the anesthetic gas and the oxygen cannot be controlled, so that the administration of the anesthetic gas is influenced.
The Chinese patent publication number is: the invention of CN109998842A discloses an anesthetic dosing operation table, which includes an operation table, a height measuring device disposed on the operation table, a target pump disposed on or beside the operation table, a weight measuring device capable of measuring weight, and a control system, wherein the height measuring device, the target pump, and the weight measuring device are respectively connected to the control system. The anesthetic quantitative operating table can accurately measure the height and the weight of a patient, conveniently and accurately measure the anesthetic amount, and conveniently and quantitatively anaesthetize by a targeting pump (TCI) after height and weight data are measured.
Although the above patent can accurately measure the height and weight of a patient to measure the dosage of anesthetic, it still does not solve the above-mentioned problems, and based on this, we propose an anesthetic dosing operation table, which hopefully solves the disadvantages of the prior art.
