Abstract

Anesthesia machine respiratory system drives gas exhaust valve, including a three-way pipe and a valve body, and the three-way pipe includes an oxygen inlet, an anesthetic gases import, an anesthesia mixed gas outlet;Being provided with the valve body on anesthetic gases jet pipe, the tube wall of the anesthetic gases jet pipe has the through hole that at least one is communicated with jet pipe inner chamber;Described anesthetic gases jet pipe one end is fixedly connected with the valve body and communicated with body cavity, and the other end sets one and the axially vertical pressure buffer piece of anesthetic gases jet pipe, and the area of the pressure buffer piece is more than the cross-sectional area of the anesthetic gases jet pipe;The valve body is connected with three-way pipe by connecting tube, and the anesthetic gases jet pipe on valve body is respectively positioned in connecting tube with the anesthetic gases import on three-way pipe, and the gap between valve body and three-way pipe and connecting tube is sealed by sealing ring.

Description

Anesthesia machine respiratory system drives gas exhaust valve
Technical field
The present invention is applied to Medical anesthetic machine anesthesia respiratory system part.Belong to Medical Devices manufacturing technology field.
Background technology
Need to be controlled respiratory system expiration end air pressure in anesthesia respiratory system, protection patient lung.Traditional implementation by mechanical compression valve, control accuracy is relatively low, pressure is unadjustable and it is complicated, be not integrated into anesthesia respiratory system complete machine together with.
The content of the invention
Present invention aim to address deficiency mentioned above.The respiratory system that the present invention is previously mentioned drives air bleeding valve by motor control pressure, pressure adjustable;Control accuracy is high, and is integrated together with anesthesia respiratory system complete machine, can be with overall disinfection.
Anesthesia machine respiratory system drives gas exhaust valve, it is characterised in that:Including a three-way pipe and a valve body, the three-way pipe includes an oxygen inlet, an anesthetic gases import, an anesthesia mixed gas outlet;Being provided with the valve body on anesthetic gases jet pipe, the tube wall of the anesthetic gases jet pipe has the through hole that at least one is communicated with jet pipe inner chamber;Described anesthetic gases jet pipe one end is fixedly connected with the valve body and communicated with body cavity, and the other end sets one and the axially vertical pressure buffer piece of anesthetic gases jet pipe, and the area of the pressure buffer piece is more than the cross-sectional area of the anesthetic gases jet pipe;The valve body is connected with three-way pipe by connecting tube, and the anesthetic gases jet pipe on valve body is respectively positioned in connecting tube with the anesthetic gases import on three-way pipe, and the gap between valve body and three-way pipe and connecting tube is sealed by sealing ring.
The present invention is in quick oxygen supply, and can eliminate influences on anaesthetic evaporator output end pressure, keeps anesthetic gases to export the stabilization of concentration, patient is shielded.

Embodiment
The present invention includes a valve body 2 of three-way pipe 1 and one, and the three-way pipe 1 includes an oxygen inlet 11, an anesthetic gases import 12, one anesthesia mixed gas outlet 13;The through hole 31 on anesthetic gases jet pipe 3, the tube wall of the anesthetic gases jet pipe 3 having at least one to be communicated with jet pipe inner chamber is provided with the valve body 2;Described one end of anesthetic gases jet pipe 3 is fixedly connected with valve body 2 and communicated with the inner chamber of valve body 2, and the other end sets one and the axially vertical pressure buffer piece 4 of anesthetic gases jet pipe, and the area of the pressure buffer piece 4 is more than the cross-sectional area of the anesthetic gases jet pipe 3;The valve body 2 is connected with three-way pipe 1 by connecting tube 5, and the anesthetic gases jet pipe 3 on valve body 2 is respectively positioned in connecting tube 5 with the anesthetic gases import 12 on three-way pipe 1, and the gap between valve body and three-way pipe and connecting tube is sealed by sealing ring 6.
In the use of the present invention, in the Anesthesia machine gas circuit shown in Fig. 1, replacing venturi valve therein with the present invention, gas flow is as shown in the direction of arrow in figure.Oxygen enters three-way pipe by the oxygen inlet 11 of three-way pipe 1, the anesthetic gases of anaesthetic evaporator output end output is exported by valve body 2 through the through hole 31 on jet pipe 3, bypass pressure buffer piece 4, enter three-way pipe through the anesthetic gases import 12 on three-way pipe 1 again, with being exported after oxygen mix by anesthesia mixed gas outlet 13.The present invention is due to the effect of pressure buffer piece 4, in quick oxygen supply, and very little is influenceed on anaesthetic evaporator output end pressure, arcotic can be kept to export concentration stable.
