Anesthesia nebulizer for medical use

Abstract

The present application relates to the technical field of anesthetic atomizer, and discloses an anesthetic atomizer for medical treatment, which comprises an atomizer, one end of the atomizer is connected with a joint pipe matched with the atomizer, and one end of the joint pipe is connected with a face mask. The face mask is heated, so that the inner wall of the face mask cannot generate water mist due to a large temperature difference with the exhaled gas of a user. By continuously blowing air outside the face mask, an "air curtain wall" is formed outside the face mask by the blown air flow, so that the cold air outside is prevented from contacting the face mask, thereby avoiding the formation of water mist outside the face mask due to the contact between the cold air and the heated face mask. Ultimately, the inside and outside of the face mask cannot generate water mist during use, thereby facilitating the observation of the breathing state of a patient by a doctor through the face mask. When not in use, the pipe opening of the conduit for blowing the air flow can be closed, so that the small dust outside is prevented from entering the conduit and clogging the conduit to affect the normal blowing of the air flow.

[0028] As shown in Figure 2 , the input assembly comprises a warm air blower 10, and the output end of the warm air blower 10 is connected with a connecting pipe, and the end of the connecting pipe away from the warm air blower 10 is threadedly connected in the inside of the input pipe 9.

[0029] The warm air blower 10 is a warm air blower capable of adjusting the temperature of the warm air in the prior art, and the temperature of the warm air for heating the mask 3 can be close to the temperature of the gas exhaled by the patient by adjusting the temperature of the output warm air flow of the warm air blower 10, so that the temperature of the mask 3 is close to the temperature of the gas exhaled by the patient.

[0030] As shown in Figure 4 and Figure 6 , the driving assembly comprises gear teeth 11 equidistantly arranged on the outside of the rubber belt 5, the bracket 4 is fixedly installed with a motor 12, and the output shaft of the motor 12 is fixedly connected with a gear 13 matched with the gear teeth 11.

[0031] The output shaft of the motor 12 is intermittently forward and reverse rotated to rotate the gear 13, and then the rubber belt 5 is rotated in cooperation with the gear teeth 11, the material of the bracket 4 is stainless steel, one side of the bracket 4 in contact with the rubber belt 5 is smooth, and the rubber belt 5 can rotate along the bracket 4.

[0032] As shown in Figures 5 to 6As shown, the connecting assembly comprises a pair of clamping plates 14, the top of the support 4 is symmetrically provided with a sliding groove, the clamping plates 14 are slidingly arranged in the sliding groove, and the sides of the two clamping plates 14 away from each other are fixedly connected with the inner wall of the sliding groove through springs 15. The pair of clamping plates 14 are clamped on the outside of the joint pipe 2.

[0033] Pulling the pair of clamping plates 14 away from each other makes the springs 15 compressed and deformed, and the clamping of the joint pipe 2 is cancelled, so that the support 4 can be separated from the joint pipe 2.

[0034] As shown in the figure, Figures 5 to 6 The outside of the support 4 is fixedly connected with a rectangular cylinder 19 through a connecting plate 16, the inside of the rectangular cylinder 19 is slidingly installed with a rectangular column 18, the top of the rectangular column 18 is rotatably installed with a lead screw 20, the lead screw 20 is threadedly connected with the top wall of the rectangular cylinder 19, the top of the lead screw 20 extends to the outside of the rectangular cylinder 19, and the bottom of the rectangular column 18 is fixedly installed with a squeezing plate 17. The conduit 6 is a rubber hose.

[0035] When not in use, the lead screw 20 is rotated in the forward direction to make it descend with the rectangular column 18, so that the squeezing plate 17 descends, the end of the conduit 6 is bent downward by the squeezing plate 17, and the support 4 squeezes the plurality of conduits 6 as the squeezing plate 17 descends, so that the end of the conduit 6 is located between the squeezing plate 17 and the support 4, and the pipe opening of the conduit 6 is pinched to close the pipe opening, so that the small dust outside cannot enter the conduit 6, which can avoid the conduit 6 being clogged for a long time and affecting the normal ejection of the air flow. The lead screw 20 is rotated in the reverse direction to make it ascend with the rectangular column 18, and the squeezing plate 17 is reset in the reverse direction to cancel the squeezing of the conduit 6, and the conduit 6 is reset under the support of its own toughness.

[0036] As shown in the figure, Figure 3 The output pipe 8 is a corrugated hose, and one end of the output pipe 8 is fixedly connected with a pipe, which is threadedly connected in the connecting pipe 7.

[0037] The pipe is rotated in the forward direction to separate it from the connecting pipe 7, so that the face mask 3 can be separated from the support 4 subsequently. The output pipe 8 is a corrugated hose, which can adapt to stretching deformation when the rubber belt 5 rotates, meeting the needs of use.

[0038] As shown in the figure, Figure 7 The face mask 3 is a transparent face mask, and the input pipe 9 is a transparent hose.

[0039] The doctor can observe the breathing state of the patient through the face mask 3, and the input pipe 9 is a transparent hose, which can avoid blocking the face mask 3, so that the doctor can observe the breathing state of the patient.

[0040] As shown in the figure, Figure 2As shown, the conduits 6, in the absence of being squeezed, maintain their own vertical state by virtue of their own toughness, and the pipe mouths of the conduits 6 are inclined towards the mask 3.

[0041] This makes it possible to ensure that the air flows blown by the plurality of conduits 6 intersect, thereby forming an "air curtain wall" outside the mask 3, and further avoiding cold air from contacting the outside of the mask 3.

[0042] Working principle: when in use, the mask 3 is worn on the face of the patient, and the anesthetic is continuously input into the mask 3 through the atomizer 1 matched with the connecting pipe 2 to anesthetize the patient, the heater 10 is started to continuously input warm air flow into the cavity 21 of the mask 3 through the matching connecting pipe and input pipe 9, so as to heat the mask 3, so that the temperature inside the mask 3 is close to the temperature of the gas exhaled by the user, so that the temperature of the inner wall of the mask 3 will not be lower than the temperature of the gas exhaled by the user, so as to ensure that no water mist is generated on the inner wall of the mask 3, the continuously input warm air flow enters the cavity of the rubber belt 5 through the output pipe 8 and the connecting pipe 7, and then fills the cavity and blows to the outside of the mask 3 through the conduit 6, the motor 12 is started to make the output shaft rotate forward and reverse intermittently, so that the gear 13 rotates with it, and then the rubber belt 5 rotates with the gear teeth 11, so that the rubber belt 5 rotates forward and reverse, so that the connecting pipe 7 rotates with it, so that the blown warm air flow can be blown to the mask 3 more comprehensively, so that the cold air outside is blown away, so that the cold air is far away from the outside of the mask 3, avoiding the contact between the cold air and the heated mask 3 outside, so as to avoid the generation of water mist on the outside of the mask 3, in the whole process, through the heating of the mask 3, the inner wall of the mask 3 will not generate water mist due to the large temperature difference with the gas exhaled by the user, through the continuous blowing outside the mask 3, an "air curtain" is formed outside the mask 3 relying on the blown air flow, so as to avoid the contact between the cold air outside and the mask 3, thereby avoiding the contact between the cold air and the heated mask 3 to form water mist outside the mask 3, finally ensuring that the mask 3 will not generate water mist on both sides during use, thereby facilitating the doctor to observe the breathing state of the patient through the mask 3; when not in use, the forward screw rod 20 makes the rectangular column 18 descend, thereby making the extrusion plate 17 descend, the extrusion plate 17 abuts against the end of the conduit 6 to make the end of the conduit 6 bend downward, and the extrusion plate 17 is lowered to extrude the multiple conduits 6 through the matching support 4, and finally the end of the conduit 6 is located between the extrusion plate 17 and the support 4, so as to clamp and flatten the pipe opening of the conduit 6, so as to close the pipe opening of the conduit 6 and avoid the entry of small dust outside into the conduit 6, which will block the conduit 6 and affect the normal blowing of the air flow after a long time, and the reverse screw rod 20 makes the rectangular column 18 rise, and vice versa to reset the extrusion plate 17 and cancel the extrusion of the conduit 6, and the conduit 6 is reset under the support of its own toughness.When the face mask 3 needs to be disassembled for replacement, the connecting pipe is rotated to be separated from the input pipe 9, the pipe is rotated to be separated from the connecting pipe 7, a pair of clamping plates 14 are pulled to move away from each other, the spring 15 is compressed to deform, the clamping of the joint pipe 2 is cancelled with the separation of the pair of clamping plates 14, the whole bracket 4 is then taken off to separate the bracket 4 from the joint pipe 2, the bracket 4 is then separated from the face mask 3, the joint pipe 2 can then be separated from the face mask 3, a new face mask 3 is then connected with the joint pipe 2, the bracket 4 is then reset, a pair of clamping plates 14 are pulled to separate them, the pair of clamping plates 14 are moved outside the joint pipe 2, the pair of clamping plates 14 are loosened, the spring 15 is reset to reset the clamping plates 14, the joint pipe 2 is clamped, the pipe is then connected with the connecting pipe 7, the connecting pipe is connected with the input pipe 9, and the replacement of the face mask 3 is completed.
