Problems solved by technology

[0003] The inventor found that the plug-in adapter plug structures of the above four anesthetic agents are different, and cannot be used in combination on the same anesthetic vaporizer
That is, on the same anesthesia vaporizer, only one of the above four anesthetic agents can be used, and the other three anesthetic agents cannot be used, resulting in repeated design and manufacture of anesthesia vaporizers, resulting in waste of resources

Embodiment Construction

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims. The same components are denoted by the same reference numerals in the drawings.

[0028] figure 1 shows an anesthesia machine vaporizer perfusion device according to the invention, figure 2 show figure 1 Plug-in adapter for use with the perfusion unit for the vaporizer of the anesthesia machine shown; image 3 show figure 2 Cutaway view of the plug-in adapter shown. Such as Figure 1 to Figure 3 As shown, a vial 11 containing an anesthetic agent is mounted on a plug-in adapter 12 during infusion using the plug-in adapter. One end 121 of the plug-in adapter 12 is adapted to the existing anesthetic drug bottle 11 for installing the drug bottle, the other end is a plug 123 , and the middle is a connecting tube 122 . Specifically, the plug 123 ha...

Abstract

The invention discloses an injection device of an anesthetic vaporizer, which comprises an injection seat, a transition sleeve and a compressing mechanism, wherein the injection seat is used for being connected with an anesthetic vaporizer main body and is provided with a filling port; the transition sleeve is hermetically mounted on the filling port of the injection seat and is provided with a plug hole for the plugging of a plug-in adapter or an injection port sealing pin, the circumferential wall of the plug hole is previously provided with at least two pin holes, and each pin hole is matched with a positioning pin of one corresponding plug-in adapter; and the compressing mechanism is arranged above the transition sleeve and is used for compressing the plug-in adapter or the injection port sealing pin. In the injection device of an anesthetic vaporizer, the different combinations of the positions of the positioning pin and the transition sleeve can realize the composite applicationof multiple anesthetics, and the additional compressing mechanism can realize zero leakage in the injection process. Besides, based on the matching between a cam and a pin, the compressing mechanism realizes the functions of reliable compression and release prevention.

Description

technical field [0001] The invention relates to a perfusion device for an anesthesia vaporizer. Background technique [0002] At present, there are three ways of adding medicine to anesthesia vaporizer: free perfusion method (fill), quick perfusion method (quickfill), plug-in adapter perfusion method (keyfill), and there are four commonly used anesthetic agents: isoflurane and sevoflurane , Enflurane, Halothane. When using the plug-in adapter perfusion method, one end of the plug-in adapter is adapted to the medicine bottle containing the anesthetic agent for installing the medicine bottle, and the plug at the other end is inserted into the socket on the perfusion seat to extract the medicine bottle from the medicine bottle. Take medicine. [0003] The inventors of the present invention have found that the plug-in adapter plug structures of the above four anesthetic agents are different, and cannot be used in combination on the same anesthetic vaporizer. That is, on the s...
