DETAILED DESCRIPTION

[0020] A vaporizer for anesthetic liquid, comprising a vaporizer shell 20, an anesthetic liquid tank 23, an inner liner body, an adapter seat 7 and an upper valve plate 12, wherein the vaporizer shell is provided with an inner liner mounting cavity 21, the anesthetic liquid tank is fixedly mounted on the outer side of the inner liner mounting cavity on the shell, the inner liner body comprises a cylinder 2, a bottom cover 1 and an upper edge plate 6, the cylinder is placed in the inner liner mounting cavity, and a gap is left between the two to form a medicine cavity 22, the upper edge plate is fixedly mounted on the outer edge of the top of the cylinder and fixedly connected to the vaporizer shell, and a curved ventilation groove 11 is provided on the upper surface of the upper edge plate, a ventilation groove air inlet 8 is provided at one end of the ventilation groove, and a ventilation groove exhaust port 9 is provided at the other end of the ventilation groove, the bottom cover is fixedly mounted on the lower part of the cylinder, the adapter seat is fixedly mounted on the upper edge plate, The upper valve plate is rotatably installed on the adapter seat, and the adapter seat is provided with an adapter seat oxygen inlet 15, an adapter seat mixed liquid medicine outlet 14, an adapter seat oxygen inlet channel and a mixed liquid medicine exhaust channel 16. The adapter seat oxygen inlet channel is divided into an inner cavity channel 19 and a medicine cavity channel 17. The inner cavity channel is connected between the adapter seat oxygen inlet and the inner cavity of the cylinder, and a temperature control valve 13 is installed in the inner cavity of the cylinder. The medicine cavity channel is connected between the adapter seat oxygen inlet and the medicine cavity. An annular adjustment groove 18 corresponding to the mixed liquid medicine outlet of the adapter seat is provided on the lower surface of the upper valve plate. The depth of the annular adjustment groove increases from shallow to deep as the annular adjustment groove extends. The ventilation groove air inlet is respectively connected to the inner cavity of the cylinder and the medicine cavity, and the ventilation groove exhaust port is connected to the mixed liquid medicine exhaust channel.

[0021] Furthermore, a spiral groove 3 is fixedly provided on the outer wall of the cylinder, and buckles 5 are fixedly provided at both ends of the spiral groove, an anesthetic liquid adsorption rope 10 is wound in the spiral groove, the upper end of the anesthetic liquid adsorption rope is fixed by the buckle, and the lower part is fixed to the spiral groove by the buckle and extended into the anesthetic liquid tank, which is beneficial to the adsorption and uniform volatilization of the anesthetic liquid and prevents the fluctuation of the liquid.

[0022] Furthermore, an adsorption sleeve 4 is mounted on the outer wall of the cylinder, which helps to promote uniform adsorption of the anesthetic liquid, and the liquid adsorbed on the anesthetic liquid adsorption rope evaporates and is evenly distributed through the adsorption sleeve before mixing with oxygen, so that the anesthetic liquid and oxygen are mixed more evenly.

[0023] The optimized, curved ventilation groove has a sine / cosine curve. The oxygen coming out of the inner cavity is mixed with the mixed anesthetic solution in a circuitous curve, which can prevent the fluctuation of the supply of the anesthetic solution due to the fluctuation of the oxygen input, especially reduce the impact of the oxygen fluctuation on the stable supply of the anesthetic solution when the ventilator is just connected.

[0024] During installation, first wind the anesthetic liquid adsorption rope into the spiral groove on the outer wall of the inner liner body, and fix one end on the buckle, and extend the other end into the liquid tank of the anesthetic liquid volatilizer, and then put the adsorption sleeve on the outside of the anesthetic liquid adsorption rope, and then install the inner liner in the inner liner installation cavity of the anesthetic liquid volatilizer, install the temperature control valve in the inner cavity of the cylinder, and then fix the adapter seat on the upper edge plate, and the upper valve plate can be rotatably installed on the adapter seat, the oxygen inlet of the adapter seat is connected to the oxygen supply equipment, and the mixed liquid outlet of the adapter seat is connected to the inhalation end of the human breathing mask.

[0025] During operation, the anesthetic liquid absorption rope absorbs the anesthetic liquid and evaporates it through the absorption sleeve. Pure oxygen enters the inner cavity from the oxygen inlet of the adapter along the inner cavity channel and passes through the temperature control valve, enters the curved ventilation groove from the ventilation groove air inlet, and finally enters the mixed liquid exhaust channel from the exhaust port of the ventilation groove, and is discharged from the mixed liquid outlet. Another route enters the medicine cavity along the medicine cavity channel, mixes with the volatilized anesthetic liquid, enters the curved ventilation groove from the ventilation groove air inlet, mixes with pure oxygen, and finally enters the mixed liquid exhaust channel from the exhaust port of the ventilation groove. After being discharged from the mixed liquid outlet, it is connected with the inhalation end of the human breathing mask for human inhalation.

[0026] Since a temperature control valve is installed in the inner cavity of the cylinder, the pressure and flow of pure oxygen can be adjusted automatically according to the temperature change. And since an annular adjustment groove corresponding to the outlet of the mixed liquid of the adapter is opened on the lower surface of the upper valve plate, the depth of the annular adjustment groove increases from shallow to deep as the annular adjustment groove extends. By rotating the upper valve plate, the different positions of the annular adjustment groove correspond to the outlet of the mixed liquid of the adapter, and the opening size of the outlet of the mixed liquid of the adapter can be adjusted, thereby adjusting the pressure and flow of the mixed liquid. It has a simple structure and is easy to adjust.

[0027] Furthermore, since a curved ventilation groove is provided on the upper surface of the upper edge plate, a ventilation groove air inlet is provided at one end of the ventilation groove, and a ventilation groove exhaust port is provided at the other end of the ventilation groove, pure oxygen and mixed liquid medicine are discharged after passing through the curved ventilation groove for human inhalation, which can reduce the fluctuation of the liquid medicine and enable the liquid medicine and oxygen to be slowly and evenly supplied.

[0028] The spiral groove and the anesthetic liquid adsorption rope on the outer wall of the cylinder are arranged to facilitate the adsorption and uniform volatilization of the anesthetic liquid, thereby further reducing the fluctuation of the liquid.

[0029] In summary, the anesthetic liquid volatilizer protected by the present invention has a simple structure, can adjust the concentration and pressure of the anesthetic liquid as needed, and the anesthetic liquid and pure oxygen are evenly mixed with little fluctuation of the liquid.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
