Problems solved by technology

[0004] The inventor found that the above three dosing methods are independent of each other and cannot be used in combination on the same anesthesia machine.
That is, on the same anesthesia machine, only one of the above three dosing methods can be used, and the other two dosing methods cannot be used, resulting in repeated design and manufacture of anesthesia machines and waste of resources

[0037] refer to Figure 1 to Figure 8 , this embodiment shows the application of the plug-in adapter in the present invention. During perfusion, the vial 19 containing the anesthetic agent is mounted on the plug-in adapter 20 (see figure 1 ), the structure of the plug-in adapter 20 is known, and one end 201 is adapted to the existing anesthetic drug bottle 19 for installing the drug bottle, the other end is a plug 203, and the middle is a connecting tube body 202 (see figure 2 ). Specifically, the plug 201 has a liquid inlet 201a and an air inlet 201b, the liquid inlet 201a communicates with the medicine taking port 203b through the channel 202a, and the air inlet 201b communicates with the exhaust port 203a through the channel 202b (see image 3 ), like this, can take medicine from the medicine bottle when the medicine bottle is installed on the plug-in adapter 20.

[0043] refer to Figure 9 to Figure 11 . This example shows the application of the free perfusion method in the present invention. The matching relationship between its cock 21 and the connecting seat 22 is as follows: Figure 10 As shown, that is, the cock 21 is directly screwed on the connecting seat 22 to block the drug inlet of the connecting seat 22 , and the connecting seat 22 is directly installed on the drug feeding port of the liquid injection seat 1 . During perfusion, directly replace the cock 21 with the medicine bottle equipped with the anesthesia machine.

[0045] refer to Figure 12 to Figure 15 . This example illustrates the use of a quickfiller in the present invention. Fig. 23 has shown the medicine bottle adapter 23 that is used to be installed on the medicine bottle, and this medicine bottle adapter 23 is installed on the connecting seat 24, and this medicine bottle adapter 23 is provided with triggering mechanism, as long as the medicine bottle is screwed on the medicine bottle adapter 23, the trigger mechanism can be started, and the connection seat 24 is given medicine. The concrete structure of the triggering mechanism of medicine bottle adapter 23 can refer to Figure 14 , the trigger mechanism 23 is well known in the rapid perfusion mode and will not be described here. In addition, the medicine bottle adapter can be taken off after filling, and the opening of the connecting seat 24 is blocked by the cock 25, so as to prevent the volatile gas from the anesthesia machine from leaking. In addition, the connection sea...

Abstract

The invention discloses an anesthetic vaporizer charging system, comprising an injection seat, a connecting seat and a charging device, wherein the injection seat is connected with the main body of the anesthetic vaporizer, and is provided with a dosing port; the connecting seat is hermetically arranged on the dosing port of the injection seat; and the charging device is arranged on the corresponding connecting seat to dose drugs for the dosing port. In the system, composite application in dosing mode for an anaesthesia machine can be realized through the connecting seat on the dosing port of the injection seat. In a plug-in adaptor charging mode, a compacting device can realize zero leakage in a charging process.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anesthesia vaporizer perfusion system. Background technique [0002] The anesthesia vaporizer is an important part of the anesthesia machine. It is a device that can convert the liquid volatile inhaled anesthetic into vapor and input it into the anesthesia circuit in a certain amount. Its function is to effectively evaporate the volatile inhaled anesthetic and accurately Control its output concentration. [0003] At present, there are three ways of adding medicine to the anesthesia vaporizer: free filling method (filler), quick filling method (quickfiller), plug-in adapter filling method (keyfiller), among them, the free filling method corresponds to the free filling device, which is completely open Infusion method; the rapid infusion method corresponds to the rapid infusion device, which is a partially open infusion method. During the infusion of the first two infusion methods...
