Description
Technical field
The utility model belongs to the field of medical instrument technology, and switching device is discharged more particularly, to a kind of Anesthesia machine exhaust gas.
Background technology
Most of Anesthesia machine on the market at present, for example, the exhaust gas discharge joint of Dreager Anesthesia machine be it is not general, mostly
Number clean by laminar flow operating room is Europe superscript and the negative pressure connector of national standard, can not connect the exhaust gas discharge head of this Anesthesia machine, be exactly phase
The connector answered can not also adjust negative pressure, cause Anesthesia machine that can not work；It needs to suck ether in vein inhalation anesthesia, it is known that ether
It is harmful for human body, the long-term sucking of pertinent literature report can allow women to cause fetal malformation after pregnancy, operating room work
Make substantial amounts of female nurse and doctress, if without corresponding exhaust gas suction device, waste gas of anesthesia can be discharged into operating room, dirty
The working environment of operating room is contaminated, long-term sucking can cause significant damage to the health of doctor and nurse.
The content of the invention
Problem to be solved in the utility model is to provide a kind of Anesthesia machine exhaust gas discharge switching device, solves Anesthesia machine row
Put the uncurrent problem of exhaust gas connection.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of Anesthesia machine exhaust gas discharge switching
Device, including adapter body, connector and protective case, the adapter body interior sets cavity and outlet pipe, described
Bayonet is set on cavity inner wall, and the connector is inserted into inside the bayonet, and the protective case is connected to the adapter body
Outside, the protective case cover the connector, and the cavity is connected with the outlet pipe, and the cavity is to be gradually reduced
Two-stage it is stepped, the end of the outlet pipe is waste gas of anesthesia gas outlet, and the outer rim of the outlet pipe sets connection tight
Fixing structure.
Further, sealing ring is further included, the sealing ring is fixed at the junction of two-stage ladder in the cavity.
Further, the connection fastening structure is laciniation.
Further, the connection fastening structure is right-angled trapezium laciniation.
Further, the connection fastening structure is wavy shaped configuration.
Further, the connector is square either circular or hexagon.
Further, the thickness of the protective case is 20-30mm.
Further, described this body by integral forming of adapter.
Further, the sealing ring is rubber seal.
The utility model has the advantages and positive effects of：Due to the adoption of the above technical scheme, a kind of anesthesia is provided
Exhaust gas discharges switching device, can be tightly connected the plug of Anesthesia machine well, has simple in structure, and sealing effect is good, convenient
Adjust negative pressure, it is easy to use the advantages that.

Specific embodiment
As depicted in figs. 1 and 2, this example includes adapter body 1, connector and protective case 2, connector insertion adapter
Inside body 1, protective case 2 is sleeved on outside adapter body 1, and adapter body 1 is made of metal material, it is preferred to use stainless steel
Material is made, and adapter body is an integral molding structure, and makes simply, processing cost is low, easy to use.
1 inside of adapter body sets cavity 6 and outlet pipe 7, cavity 6 to be connected with outlet pipe 7, outlet pipe 7
One end is waste gas of anesthesia air inlet 5, and the diameter of outlet pipe 7 is less than the diameter of cavity 6, thus cavity 6 and outlet pipe 7 it
Between form a backstop position, cavity 6 is the two-stage step structure being gradually reduced, and bayonet 3, bayonet 3 are set on cavity inner wall
In the middle part of first order ladder, the junction of two-stage ladder sets sealing ring 4, and sealing ring 4 is the rubber for having certain elasticity
Sealing ring, favorable sealing property.The outlet of lung ventilator is inserted into cavity 6, is sealed by sealing ring 4, ensures outlet end card
At backstop position.
The end of outlet pipe 7 is waste gas of anesthesia gas outlet 8, and the outer rim of outlet pipe 7 sets connection fastening structure, connection
Fastening structure 9 plays the role of anticreep, and connection fastening structure 9 is arranged to laciniation, and section is right-angled trapezium or connection
Fastening structure 9 is wavy shaped configuration, and section is S types, can be risen during being connected with the connecting line of wall negative pressure device
To good anti-off effect, ensure that connecting line will not fall off.Because the pipeline diameter being connected with wall negative pressure device is 7mm,
Preferably, the sawtooth end of adapter is also 7mm, ensures the tight fit of adapter and pipeline.
Inside connector insertion bayonet 3, it is fitted close with bayonet 3.Bayonet 3 can be arbitrary shape, such as square, circle
Shape, hexagon etc., connector are, circular, hexagon etc. close-fitting square with bayonet 3.Protective case 2 is sleeved on adapter,
The thickness of protective case 2 is 20-30mm, can cover connector and block bayonet 3, ensures sealing performance.
The course of work of this example：Adapter body uses integrated formed structure, and when work connects lung ventilator gas outlet
Sealing ring is inserted into the cavity of adapter body, and lung ventilator gas outlet snaps into backstop position, the machine that ensures respiration outlet and switching
Head is tightly connected, and insertion connector and bayonet are fitted close, and connector is covered with protective case, the other end of adapter body with
The pipeline connection of wall negative pressure device, can adjust negative pressure.
The beneficial effects of the utility model are：Switching device is discharged by Anesthesia machine exhaust gas and connects Anesthesia machine, such as Dare
The plug of lattice Anesthesia machine, it may be convenient to access adjustable Europe superscript or national standard connector, and then solve Anesthesia machine interface cannot
The problem of being applied on all negative pressure connectors, causing negative pressure that cannot adjust.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
