Abstract

The utility model provides a circulation closed anesthetic machine, which belongs to the technical field of medical instruments. The circulation closed anesthetic machine adopts the structure that an anesthetic vaporizer, a four-way pipe, screw thread soft tubes and a carbon dioxide absorber are connected in series to a circulation pipeline in sequence; both an air escape valve and a buffering air bag are connected to the four-way pipe; two sections of screw thread soft tubes are separately butted with a three-way pipe; a respiratory face mask is connected on the three-way pipe; an inspiration valve is arranged between the four-way pipe and the screw thread soft tube on the circulation pipeline; an expiratory valve is arranged among the screw thread soft tubes and the carbon dioxide absorber; and an oxygen generating device is connected to the circulation pipeline between the carbon dioxide absorber and the anesthetic vaporizer. The circulation closed anesthetic machine is mainly used for maintenance after anesthetization, and has the advantages of reasonable design, simple structure, safety, reliability, convenient use, easy maintenance, small quantity of air flow, easy anesthetic gas concentration control, and no pollution to the environment.

Description

Airtight anesthetic machine circulates

Technical field

This utility model relates to technical field of medical instruments, the airtight anesthetic machine of specifically a kind of circulation.

Background technology

General, in internal medicine operation or the internal medicine diagnoses and treatment process, can need that at the different state of an illness patient is carried out all types of anesthesia and cooperate operation or diagnosis to carry out, obtain medical treatment accurately or treatment effect with convenient.But, at some special operation or diagnosis and treatment, then need the long time that the patient is kept anesthesia, if generally adopt fix anesthesia, the time is difficult to control, but the anesthesia equipment of major surgery wastes one's talent on a petty job again, causes waste to a certain extent.How to design a kind of easy device of keeping anesthesia and be that internal medicine is clinical that an important topic to be solved arranged.

Summary of the invention

Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of circulation airtight anesthetic machine.

The technical solution of the utility model realizes in the following manner, this airtight anesthetic machine that circulates, its structure is to be in series with anaethetic evaporator on the circulation line successively, four-way pipe, the screw thread flexible pipe, CO2 absorber system, be connected with ease gas flap valve and buffer air bag on the four-way pipe respectively, the screw thread flexible pipe is two sections and is docked on the tee T respectively, also be connected with breathing mask on the tee T, be provided with inspiratory valve between four-way pipe on the circulation line and the screw thread flexible pipe, be provided with expiratory valve between screw thread flexible pipe and the CO2 absorber system, be connected with oxygen generator on the circulation line between CO2 absorber system and the anaethetic evaporator.

Described oxygen generator adopts oxygen pipeline or oxygen cylinder.

The beneficial effect that this utility model is compared with prior art produced is:

This airtight anesthetic machine that circulates is mainly used in keeping after the induced anesthesia, reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, during air-breathing after the patient wears, mixed anesthesia gas is finished in the screw thread flexible pipe lung by open inspiratory valve, during expiration, inspiratory valve is closed, breath enters CO2 absorber system through expiratory valve, arrives buffer air bag again, and air-flow is done the circulating one-way flow of circumference, therefore, throughput is little, and it is few to expend the anesthesia dose, is easy to control the concentration of anesthetic gases, do not communicate in the external world, easily keep the moistening of respiratory tract, reduce the forfeiture of body heat, free from environmental pollution, and can implement auxiliary and control breathing by buffer air bag, and observe the size of tidal volume and the variation of respiratory resistance.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Labelling in the accompanying drawing is represented respectively:

1, oxygen generator, 2, circulation line, 3, anaethetic evaporator, 4, four-way pipe, 5, ease gas flap valve, 6, buffer air bag, 7, inspiratory valve, 8, the screw thread flexible pipe, 9, tee T, 10, breathing mask, 11, expiratory valve, 12, CO2 absorber system.

The specific embodiment

Below in conjunction with accompanying drawing the airtight anesthetic machine of circulation of the present utility model is done following detailed description the in detail.

As shown in Figure 1, the airtight anesthetic machine of circulation of the present utility model, its structure is to be in series with anaethetic evaporator 3 on the circulation line 2 successively, four-way pipe 4, screw thread flexible pipe 8, CO2 absorber system 12, be connected with ease gas flap valve 5 and buffer air bag 6 on the four-way pipe 4 respectively, screw thread flexible pipe 8 is two sections and is docked at respectively on the tee T 9, also be connected with breathing mask 10 on the tee T 9, be provided with inspiratory valve 7 between four-way pipe 4 on the circulation line 2 and the screw thread flexible pipe 8, be provided with expiratory valve 11 between screw thread flexible pipe 8 and the CO2 absorber system 12, be connected with the oxygen generator 1 that oxygen pipeline or oxygen cylinder provide as oxygen on the circulation line between CO2 absorber system 12 and the anaethetic evaporator 3.

Claims (2)

1, airtight anesthetic machine circulates, it is characterized in that being in series with successively on the circulation line anaethetic evaporator, four-way pipe, the screw thread flexible pipe, CO2 absorber system, be connected with ease gas flap valve and buffer air bag on the four-way pipe respectively, the screw thread flexible pipe is two sections and is docked on the tee T respectively, also be connected with breathing mask on the tee T, be provided with inspiratory valve between four-way pipe on the circulation line and the screw thread flexible pipe, be provided with expiratory valve between screw thread flexible pipe and the CO2 absorber system, be connected with oxygen generator on the circulation line between CO2 absorber system and the anaethetic evaporator.
2, the airtight anesthetic machine of circulation according to claim 1 is characterized in that described oxygen generator adopts oxygen pipeline or oxygen cylinder.
