Problems solved by technology
[0003] Generally, anesthesia gas inhalation requires the use of an anesthetic gas delivery device to inhale anesthetic gas to the patient, but the existing anesthetic gas delivery device still has certain problems in the mixed delivery efficiency of anesthetic gas, for example, it is difficult to automatically adjust the mixed gas pressure during use The balance of the anesthetic gas and oxygen will affect the mixing efficiency of the anesthetic gas and oxygen, and affect the concentration and dose of the anesthetic gas inhaled by the patient. At the same time, the existing devices generally have no gas heating or temperature control methods, which are relatively traditional, slow heating, poor response, and poor use effect, etc. Wait

experiment example
[0051] Experimental example: After the patient puts on the breathing mask, the MAP value does not increase significantly and the heart rate does not change significantly. The time from inhaling the anesthetic gas to the loss of consciousness is 3-4 minutes;
[0052] Simultaneously, make these 100 routine patients carry out inhalation anesthesia using comparative example and experimental example device respectively, and have carried out investigation to using inhalation feeling, and patient is 97% to experimental example device use satisfaction satisfaction; 78%;
[0053] Conclusion: Using the device of the present invention has better delivery effect, stable output, precise adjustment of anesthetic gas concentration and temperature, improved inhalation anesthesia effect and improved patient experience.

The invention discloses an anesthetic gas delivery device, which mainly includes a device main body, an oxygen equalizing tank, an anesthesia pressure equalizing tank, a controller and a breathing mask; the main body of the device is cylindrical, and the upper part is provided with a cylindrical groove, and The main body of the device below the tank is provided with a mixing chamber and a heating chamber in sequence from top to bottom. The oxygen pressure equalizing tank and the anesthesia pressure equalizing tank are equidistant and staggered against the peripheral wall of the cylindrical groove of the main body of the device. The cylindrical shape of the main body of the device The upper end of the groove is provided with a fixed plate, and the left and right ends of the top surface of the fixed plate are respectively provided with an oxygen connection valve and an anesthetic gas connection valve. There are two distribution pipes under the fixed plate. The connection ports of the two air distribution pipes are connected. In a word, the mixed delivery effect of the device of the present invention is better, and the concentration and temperature of the anesthetic gas can be adjusted according to the breathing temperature and frequency of the patient, and the adjustment is intelligent and precise.
Description
technical field [0001] The invention relates to the technical field of anesthesia medical instruments, in particular to an anesthetic gas delivery device. Background technique [0002] Inhalation of anesthetic drugs enters the human body through the respiratory tract in the form of volatile gases to form an anesthetic effect. Such drugs include ether, isoflurane, nitrous oxide, etc., enter the blood through the alveolar artery, and then pass through the blood-brain barrier with the blood circulation. The brain, entering the central nervous system, it can block the function of neurotransmission and play an anesthetic role. [0003] Generally, anesthesia gas inhalation requires the use of an anesthetic gas delivery device to inhale anesthetic gas to the patient, but the existing anesthetic gas delivery device still has certain problems in the mixed delivery efficiency of anesthetic gas, for example, it is difficult to automatically adjust the mixed gas pressure during use The...
