Embodiment Construction
[0021] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0022] see Figure 1-Figure 5 , a passive portable anesthesia machine, including a box body 2, a breathing circuit 14, an exhalation circuit 7, and an oxygen tube 15 communicated with an oxygen source. There is an anesthetic waste gas absorption device. The anesthetic waste gas absorption device includes an anesthetic storage tank 5, a waste gas absorption particle storage tank A8 and a waste gas absorption particle storage tank B9. The anesthetic drug storage tank is equipped with a waste gas absorption particle storage tank A, and the waste gas absorption particle storage The exterior of the tank A is equipped with an exhaust gas absorption particle storage tank B. A plurality of air outlet holes 5-1 are formed at the bottom of the anesth...

The invention relates to a passive portable anesthesia machine, which includes a box body, a breathing pipeline, an exhalation circuit and an oxygen tube. device, the anesthetic waste gas absorption device includes an anesthetic storage tank, a waste gas absorption particle storage tank A and a waste gas absorption particle storage tank B, the waste gas absorption particle storage tank A is connected to a waste gas pressure reducing valve A at the bottom, and the anesthetic gas concentration control device is connected to a bottom Anesthesia main exhaust pipe and anesthetic secondary exhaust pipe, one end of the exhalation circuit extends out of the box, the other end communicates with waste gas absorption particle storage tank B, the oxygen tube communicates with the anesthetic gas concentration control device, the breathing circuit communicates with the anesthetic The secondary exhaust pipe is connected. The advantages are: light weight, wide application range, no need for external power supply, and can maintain a constant concentration of volatile anesthetic drugs; use water and carbon dioxide in the patient's exhaled breath to react with the anesthetic waste gas absorption device to generate heat to maintain a constant temperature of anesthetic drugs.
Description
technical field [0001] The invention belongs to the technical field of medical devices, in particular to a passive portable anesthesia machine. Background technique [0002] Inhalation anesthesia is an important part of general anesthesia. Its characteristics are: fast onset, quick recovery, strong controllability, stable breathing cycle, no metabolism in the body and no residue, etc. It is currently widely used in the field of anesthesia and labor pain. The traditional evaporator is equipped with a large amount of cotton yarn with strong siphon force and a large surface area, which is convenient for volatile anesthetic drugs to volatilize from liquid to gaseous state, and the bottom of the cotton yarn is in contact with the liquid medicine. The exogenous oxygen entering the evaporator is divided into the part that passes through the volatile anesthetic (normal path) and the part that does not pass through the volatile anesthetic (bypass) through the control device. As the...
