Description

Technical Field

[0001] The present invention relates to the technical field of medical respiratory devices, in particular to a respiratory device with an atomization function. Background Art

[0002] In clinical medicine, the ventilator is currently the most widely used and convenient artificial respiration support tool. It is a device that can assist or control breathing, increase lung throughput, improve respiratory function, reduce the work of breathing, and alleviate the burden on the heart and lungs. A ventilator used clinically generally consists of a gas delivery pipeline, a gas inlet and outlet located on the pipeline, and an air reservoir bag that is used in conjunction with a mask or endotracheal tube to control or assist breathing.

[0003] For example, the patent application with publication number CN105688315A discloses a nebulizer respirator, which includes a nebulizer cup, an air inlet pipe and an atomizer output pipe, and the atomizer output pipe is connected to an air storage bag through a valve; the atomizer output pipe is composed of a hard pipe, a main hose and a secondary hose, one end of the main hose is connected to the mask through a connecting elbow, and one end of the secondary hose is connected to the air storage bag through an air supply elbow; the hard pipe is provided with a support frame for supporting the hard pipe and with adjustable height; the air inlet pipe is provided with an air inlet one-way valve; the connecting elbow is provided with an exhalation one-way valve; a strap for fixing the mask is provided at the connection between the connecting elbow and the mask; and an inflation ring with an inflation nozzle is provided at the bottom edge of the mask.

[0004] Although the above application can complete the atomization of the medicine, the output air pressure of the atomization output tube is difficult to control during the atomization work. When the output air pressure is too low, the atomization work will fail. Therefore, the actual air pressure value is greater than the established air pressure value.

DETAILED DESCRIPTION

[0055] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0057] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0058] The present invention discloses a breathing device with atomization function, referring to Figures 1-16 ,include:

[0059] The pressurized airbag 1 and the connecting tube 4 are used to connect the air supply pipe 6 of the pressurized airbag 1 and the connecting tube 4, as well as the mask 10, the connecting seat 3, the press switch 9 and the pressure gauge 2 respectively connected to the connecting tube 4, and the pressure relief unit 5 connected to the connecting seat 3; the atomization unit 7 is detachably installed between the air supply pipe 6 and the connecting tube 4, and the atomization unit 7 is used to atomize the medicine, and by manually pressing the pressurized airbag 1, the air pressure in the connecting tube 4 is adjusted to allow the atomized medicine to enter the human body; the press switch 9, the pressure relief unit 5 and the pressure gauge 2 form a protection mechanism, and by observing the number on the pressure gauge 2, the press switch 9 is manually opened or the pressure relief unit 5 is automatically opened to relieve the pressure, thereby adjusting the air pressure value in the connecting tube 4; when needed When assisting the patient in breathing, the pressurized airbag 1 is pressed to generate a high-speed airflow, which flows into the connecting tube 4 along the air supply tube 6. When the patient exhales through his nose, the air pressure in the connecting tube 4 increases. At this time, the air pressure in the connecting tube 4 can be monitored by observing the value of the pressure gauge 2. When the air pressure exceeds the predetermined pressure, the airflow in the connecting tube 4 can be discharged by driving the press switch 9 or the pressure relief unit 5 to self-relieve the pressure, thereby reducing the air pressure in the connecting tube 4 and avoiding excessive air pressure, which may damage the patient's airway when the patient inhales. The atomizer unit 7 is provided to atomize the medicine, so that the medicine can enter the human body in the form of small droplets, completing the atomization of the human body.

[0060] The push switch 9 includes a connecting ring arranged on the circumference of the connecting pipe 4, a connecting spring 93 connected to the connecting ring and sleeved on the connecting pipe 4, a sealing seat 91 connected to one end of the connecting spring 93 and sleeved on the connecting spring 93, a driving rod 92 and two limit blocks 94 respectively arranged on the sealing seat 91, and a limit frame 95 arranged on the connecting pipe 4; one end of the limit block 94 extends into the limit frame 95 and extends a certain distance toward the inner wall of the limit frame 95; the connecting spring 93 is in a stretched state, so that the bottom of the sealing seat 91 abuts against the connecting pipe 4; when the push switch 9 is pressed, the bottom of the sealing seat 91 abuts against the connecting pipe 4. When the value of the force meter 2 exceeds the predetermined value, the medical staff can hold the driving rod 92 and move the driving rod 92 in the direction away from the mask 10, so that the sealing seat 91 is away from the connecting pipe 4, and a gap appears between the connecting pipe 4 and the sealing seat 91, thereby completing the pressure relief work. After the pressure relief work is completed, the medical staff releases the driving rod 92, and the sealing seat 91 is driven by the connecting spring 93 to abut against the connecting pipe 4, completing the sealing of the connecting pipe 4, and then when the pressurized airbag 1 is pressed, the air pressure in the connecting pipe 4 can be increased. The gas for pressure relief by pressing the switch 9 is generally dry gas.

[0061] The atomizing unit 7 is also provided with a liquid injection unit 8; the atomizing unit 7 includes a transfer tube 71 for connecting the air delivery pipe 6 and the connecting pipe 4, a plurality of reinforcing ribs arranged in the transfer tube 71, a medicine cup 72 for connecting the reinforcing ribs, and a stopper 73 located in the medicine cup 72; the bottom of the medicine cup 72 is recessed toward the stopper 73 to form a conical protrusion 74 in the medicine cup 72, and an air flow channel is opened in the conical protrusion 74; the stopper 73 is provided with a rectangular through hole, a first groove connected to the rectangular through hole, and a plurality of second grooves opened on the inner wall of the first groove; the first groove is adapted to the conical protrusion 74, and the first groove is sleeved on the conical protrusion 74; the inner wall of the medicine cup 72 is connected to the stopper The area between the outer surfaces of the conical protrusion 74 is used to hold the medicine, and the second groove is used for the flow of the medicine; when the medicine needs to be atomized, a high-speed airflow is generated by pressing the pressurized airbag 1, and then the airflow passes through the atomization unit 7 along the air supply pipe 6, and the airflow passes through the air flow channel in the conical protrusion 74. Due to the conical structure of the conical protrusion 74 and its diameter gradually decreasing with the direction of movement of the airflow, the flow rate of the airflow is increased, so that the medicine in the medicine cup 72 moves along the second groove and merges with the airflow at the outlet end of the conical protrusion 74. The airflow carries the medicine and hits the block seat 73, and then can be atomized. The atomized medicine can enter the human body during the airflow or human breathing, completing the atomization treatment of the patient.

[0062] During the nebulization process, in order to avoid the air pressure being too high during nebulization and causing the airflow to damage the patient's airway, a pressure relief unit 5 is provided. The pressure relief unit 5 is an active pressure relief method. When the air pressure in the connecting pipe 4 exceeds the preset value, the pressure relief unit 5 starts automatically to complete the pressure relief work. However, since the gas during pressure relief contains more small liquid particles, it will cause the medicine to splash, thereby causing environmental pollution.

[0063] In order to solve the above problems, the pressure relief unit 5 in the present device includes an injection assembly 53 connected to the connecting seat 3, and a water removal assembly 51 connected to the injection assembly 53; the water removal assembly 51 includes an inner tube 513, an outer tube 521 sleeved on the inner tube 513 and connected to the outer wall of the inner tube 513, an air inlet pipe 512 arranged on the outer tube 521, a water blocking portion built into the inner tube 513, and a breathable plate 520 and a holding cup 511 respectively arranged at both ends of the outer tube 521; the outer tube 521 is provided with an external thread, and the holding cup 511 is threadedly connected to the outer tube 521; the inner tube 513 is a reducing tube, and the diameter of the inner tube 513 gradually decreases as it approaches the ends of the inner tube 513, so that there is a gap between the ends of the inner tube 513 and the outer tube 521; the inner tube 513 is provided with a plurality of water outlet holes 514 and air outlet holes 515 at a position close to the air inlet pipe 512, the air inlet pipe 512 is located between the air outlet holes 515 and the water outlet holes 514, and the air outlet holes 515 are located above the water outlet holes 514; a plurality of water outlet holes are provided at the connection between the first parachute separator 516 and the inner tube 513;

[0064] Through the above-mentioned pressure relief unit 5, when the air flow carrying water vapor passes through the air inlet pipe 512 and enters the gap between the inner tube 513 and the outer tube 521, the air flow can contact the outer wall of the inner tube 513, and the liquid in the air flow can adhere to the outer wall of the inner tube 513 and fall into the holding cup 511 along the gap between the outer wall of the inner tube 513 and the inner wall of the outer tube 521, and then the air flow enters the inner tube 513 along the air outlet hole 515, and then the air flow passes through the first umbrella plate separator 516 and the second umbrella plate separator 517 in turn, and then the air flow can be discharged into the air from the air permeable plate 520 in the inner tube 513, and the liquid carried in the air flow can form water droplets under the obstruction of the first umbrella plate separator 516 and the second umbrella plate separator 517, and drip into the holding cup 511 below, reducing the amount of water vapor carried in the air flow and avoiding a large amount of medicine being sprayed into the air during the pressure relief process.

[0065] The water blocking portion includes a first umbrella plate separator 516 arranged in the inner tube 513, a water outlet seat 518 connected to the first umbrella plate separator 516, and a second umbrella plate separator 517 connected to the water outlet seat 518; the first umbrella plate separator 516 and the second umbrella plate separator 517 are provided with a plurality of water leakage holes and are truncated cone-shaped structures, the upper end surfaces of the first umbrella plate separator 516 and the second umbrella plate separator 517 are respectively connected to the water outlet seat 518, and the water outlet seat 518 is also provided with a conical water collecting hole in the direction close to the second umbrella plate separator 517; the water blocking portion also includes a mounting seat 519 arranged in the water outlet seat 518, and a mounting seat 519 evenly arranged on the mounting seat 519. The guide channels 522 include a first channel 5221 formed in the mounting base 519, a plurality of second channels 5222 respectively connected to the first channel 5221, a third channel 5223 connected to the second channels 5222, and a fourth channel 5224 for connecting the third channels 5223 and the first channel 5221. The third channel 5223 is an arc-shaped channel, and the second channel 5222 is parallel to the fourth channel 5224. When airflow enters the guide channel 522 from one end of the first channel 5221, the airflow discharged from the fourth channel 5224 can hinder the airflow in the first channel 5221.

[0066] When the airflow passes through the water blocking portion, the droplets carried in the airflow can adhere to the first umbrella plate separator 516 and the second umbrella plate separator 517 when the airflow passes through the first umbrella plate separator 516 and the second umbrella plate separator 517. When there are too many attached droplets, the droplets can fall along the first umbrella plate separator 516 and the second umbrella plate separator 517 to a predetermined position, completing the collection of water vapor carried in the airflow. However, in actual operation, although the second umbrella plate separator 517 is provided with a plurality of water leakage holes, since the water leakage holes are not seamlessly connected and are a truncated cone structure, the water flow will be gathered at the bottom of the second umbrella plate separator 517. At this time, the water flow at this position The water flow can enter the guide channel 522 along one end of the first channel 5221, and then be discharged from the other end of the first channel 5221 through the set first channel 5221, and then fall into the holding cup 511 below. At the same time, since the third channel 5223 is an arc-shaped channel, the second channel 5222 is parallel to the fourth channel 5224. Therefore, when the airflow enters the guide channel 522 from one end of the first channel 5221, the airflow discharged from the fourth channel 5224 can hinder the airflow in the first channel 5221, preventing the airflow carrying water vapor from being discharged from the guide channel 522, thereby reducing the water vapor carried in the airflow and ensuring the smooth progress of the pressure relief work.

[0067] The jet assembly 53 includes a support seat 531, an air inlet end 532 arranged on the support seat 531 and connected to the connecting seat 3, an accommodating cavity provided in the support seat 531, an adjusting nut 533 screwed to the support seat 531, an adjusting screw 537 connected to the adjusting nut 533 and extending into the accommodating cavity, a limiting seat 535 sleeved on the adjusting screw 537, an adjusting spring 534 for connecting the limiting seat 535 and the adjusting nut 533, and a limiting ball 536 provided on the limiting seat 535; an air outlet end is also provided on the support seat 531, and the air outlet end is used to release the air to the Gas is transported in the air inlet pipe 512, and the limiting ball 536 is in contact with the air outlet of the air inlet end 532; before the air is released, the adjusting nut 533 is rotated to change the position of the adjusting screw 537 between the limiting seats 535, thereby changing the deformation of the adjusting spring 534 and adjusting the pressure of the limiting ball 536 on the support seat 531. When the gas pressure in the connecting pipe 4 is greater than the squeezing force of the limiting ball 536 on the support seat 531, a gap appears between the limiting ball 536 and the air outlet of the air inlet end 532. The gas passes through the air inlet end 532 and the accommodating cavity and is discharged from the air outlet on the support seat 531 and enters the dewatering component 51.

[0068] The injection unit 8 includes an injection tube 87 connected to the medicine cup 72, a fixing seat 81 provided on the transfer tube 71, two injection cylinders 82 symmetrically provided on the fixing seat 81, an adjusting member connected to one end of the injection cylinder 82, and a connecting tube 86 for connecting the two adjusting members; the adjusting member also includes a valve seat 83 connected to the injection cylinder 82, a valve core 84 built into the valve seat 83, and a knob 85 connected to the valve core 84; the valve core 84 is provided with a receiving groove; when When it is necessary to inject medicine into the medicine cup 72, the knob 85 is turned at this time. The moving knob 85 can move the valve core 84, so that the receiving groove is opposite to the injection cylinder 82, and then the knob 85 is turned again. Since the valve core 84 abuts against the inner wall of the valve seat 83, the groove in the valve core 84 can transport the medicine, so that the medicine can be discharged from the injection tube 87, completing the addition of medicine to the medicine cup 72. Different medicines can be added through the two injection cylinders 82.

[0069] In a further embodiment, the pressurized airbag 1 is respectively provided with an inlet and an outlet, wherein the outlet is connected to one end of the air supply pipe 6, and the connecting pipe 4 is a T-shaped structure; the sealing seat 91 may also be provided with a sealing gasket, and the connecting pipe 4 is sealed by using the sealing gasket; the connecting seat 3 is provided with an air flow channel; the pressurized airbag 1 can be replaced with an electric compression pump.

[0070] In a further embodiment, in order to avoid the patient being unable to adjust the press switch 9 after surgery, the above-mentioned press switch 9 is removed in this embodiment and two independent corrugated bellows 11 are provided, and a one-way valve is provided on the corrugated bellows 11, wherein the valves on the two corrugated bellows 11 are in opposite directions. In this embodiment, there are two air supply pipes 6, which are respectively connected to the two corrugated bellows 11 and then connected to the atomization unit 7 or the connecting pipe 4. When the patient squeezes one of the corrugated bellows 11, the corrugated bellows 11 can inflate, while the other corrugated bellows 11 exhausts air outward, thereby achieving the respiratory assistance effect for the patient without driving the press switch 9.

[0071] Working principle description: When the patient needs to be assisted in breathing, the pressurized airbag 1 is pressed to generate a high-speed airflow, which flows into the connecting pipe 4 along the air supply pipe 6. When the patient exhales through the nose, the air pressure in the connecting pipe 4 increases. At this time, the air pressure in the connecting pipe 4 can be monitored by observing the value of the pressure gauge 2. When the air pressure exceeds the predetermined pressure, the airflow in the connecting pipe 4 can be discharged by driving the press switch 9 or the pressure relief unit 5 to self-release the pressure, thereby reducing the air pressure in the connecting pipe 4; when the pressure When the value in Table 2 exceeds the predetermined value, the medical staff can hold the driving rod 92 and move the driving rod 92 away from the mask 10, thereby moving the sealing seat 91 away from the connecting pipe 4, so that a gap appears between the connecting pipe 4 and the sealing seat 91, thereby completing the pressure relief work. After the pressure relief work is completed, the medical staff releases the driving rod 92, and the connecting spring 93 drives the sealing seat 91 to abut against the connecting pipe 4, completing the sealing of the connecting pipe 4, and then when the pressurized airbag 1 is pressed, the air pressure in the connecting pipe 4 can be increased;

[0072] When it is necessary to atomize the medicine, a high-speed airflow is generated by pressing the pressurized airbag 1, and then the airflow passes through the atomizing unit 7 along the air delivery pipe 6, and the airflow passes through the airflow flow channel in the conical protrusion 74. Due to the conical structure of the conical protrusion 74 and its diameter gradually decreasing with the movement direction of the airflow, the flow rate of the airflow is increased, so that the medicine in the medicine cup 72 moves along the second groove and merges with the airflow at the outlet end of the conical protrusion 74. The airflow carries the medicine and hits the block seat 73, and then it can be atomized. The atomized medicine can enter the human body during the airflow or human breathing, completing the atomization treatment of the patient; when the airflow carrying water vapor enters the inner tube 513 and the inner tube 513 through the air inlet pipe 512, the medicine is atomized. When there is a gap between the outer tube 521, the air flow can contact the outer wall of the inner tube 513, and the liquid in the air flow can adhere to the outer wall of the inner tube 513 and fall into the holding cup 511 along the gap between the outer wall of the inner tube 513 and the inner wall of the outer tube 521. The air flow enters the inner tube 513 along the air outlet 515, and the air flow passes through the first umbrella plate separator 516 and the second umbrella plate separator 517 in sequence. The air flow can be discharged into the air from the air permeable plate 520 in the inner tube 513, and the liquid carried in the air flow can form water droplets under the obstruction of the first umbrella plate separator 516 and the second umbrella plate separator 517, and drip into the holding cup 511 below, thereby reducing the amount of water vapor carried in the air flow and avoiding the occurrence of water vapor in the pressure relief process. , a large amount of medicine is sprayed into the air; when the airflow passes through the water blocking part, the droplets carried in the airflow can adhere to the first umbrella plate separator 516 and the second umbrella plate separator 517 when the airflow passes through the first umbrella plate separator 516 and the second umbrella plate separator 517. When there are too many attached droplets, the droplets can fall along the first umbrella plate separator 516 and the second umbrella plate separator 517 to a predetermined position, completing the collection of water vapor carried in the airflow. However, in actual operation, although the second umbrella plate separator 517 is provided with a plurality of water leakage holes, the water leakage holes are not seamlessly connected and are a truncated cone structure, which will cause the water flow to gather at the bottom of the second umbrella plate separator 517. At this time, the water flow at this location can enter the guide channel 522 along one end of the first channel 5221, and then be discharged from the other end of the first channel 5221 through the provided first channel 5221, and then fall into the holding cup 511 below. At the same time, because the third channel 5223 is an arc-shaped channel, the second channel 5222 is parallel to the fourth channel 5224. Therefore, when the airflow enters the guide channel 522 from one end of the first channel 5221, the airflow discharged from the fourth channel 5224 can hinder the airflow in the first channel 5221, preventing the airflow carrying water vapor from being discharged from the guide channel 522, thereby reducing the water vapor carried in the airflow and ensuring the smooth performance of the pressure relief work;

[0073] Before the air is released, the adjusting nut 533 is turned to change the position of the adjusting screw 537 between the limiting seats 535, thereby changing the deformation of the adjusting spring 534 and adjusting the pressure of the limiting ball 536 on the support seat 531. When the gas pressure in the connecting pipe 4 is greater than the squeezing force of the limiting ball 536 on the support seat 531, a gap appears between the limiting ball 536 and the air outlet of the air inlet end 532. The gas passes through the air inlet end 532 and the accommodating cavity and is discharged from the air outlet end on the support seat 531 and enters the water removal component 5 1; when it is necessary to inject medicine into the medicine cup 72, the knob 85 is turned at this time. The moving knob 85 can move the valve core 84, so that the receiving groove is opposite to the injection cylinder 82, and then the knob 85 is turned again. Since the valve core 84 abuts against the inner wall of the valve seat 83, the groove in the valve core 84 can carry the medicine, so that the medicine can be discharged from the injection tube 87, completing the addition of medicine to the medicine cup 72. Different medicines can be added through the two injection cylinders 82 to complete the addition of different medicines.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
