Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an atomization medicine delivery device. Background Art

[0002] Nebulizer therapy refers to using a nebulizer to vibrate the drug solution at high speed or evaporate it at high temperature into a gas state, and then putting the gaseous drug solution into the patient's ventilator or the patient's ward. The patient can directly inhale the drug solution by breathing air, and the small molecule drug solution can also adhere to the patient's skin and be inhaled into the human body through the skin. Its therapeutic effect is much higher than the treatment method of drug injection or intravenous drip, which can greatly relieve the patient's pain;

[0003] Traditional nebulizer therapy devices can usually only nebulize one liquid medicine at a time. When nebulizing another liquid medicine, the liquid medicine needs to be replaced.

[0029] The feed pipe 29 passes through the slider 32 and is connected with the upper area of ​​the mixing chamber 7. The feed pipe 29 is composed of a middle bellows 292 and two elastic tubes 291 at both ends. A solenoid valve is provided inside the feed pipe 29 to control the on and off. A cutting blade 36 is fixed to the lower part of the stirring shaft 34. A dosing pipe 37 is installed at the upper end of the mixing chamber 7. A sealing plug 38 is installed at the upper end of the dosing pipe 37. The presence of the cutting blade 36 can break the tablets so that the tablets can be quickly dissolved in the medicine solution, so that the tablets can also be quickly put into atomization for use, thereby expanding the scope of atomization medication.

[0030] The quantitative drug supply mechanism includes a pump medicine chamber 11 opened on the upper part of the medicine storage box 3, a medicine filling tube 10 is installed at the bottom of the medicine storage box 3, a medicine extraction needle 13 is installed through the bottom of the pump medicine chamber 11, the inner bottom of the pump medicine chamber 11 is connected to a pump medicine ring 121 through a pump medicine spring 12, and a transfer tube 15 is installed on the top of the pump medicine chamber 11. The transfer tube 15 is connected to the feeding tube 16, and the transfer tube 15, the pump medicine ring 121, the medicine extraction needle and the feeding tube 16 are all provided with a one-way valve inside. An electromagnet 14 is fixed on the top of the medicine storage box 3, and the electromagnet 14 attracts the pump medicine ring 121 to complete the extraction and transfer of the medicine liquid. The greater the power intensity of the electromagnet 14, the greater the displacement of the pump medicine ring 121, and the greater the actual single pump medicine amount, so that the single medicine liquid transfer amount can be controlled. Combined with the supply of multiple medicine liquids, the precise proportion supply of a single medicine liquid can be achieved, making the medicine liquid atomization supply process more reasonable and effective.

[0031] A water tank 17 is installed inside the chassis 1, and a water pump 18 is installed inside the water tank 17. The water outlet of the water pump 18 is connected to the feeding pipe 16. An electric heating rod 19 is installed on the inner wall of the water tank 17. A heat exchange pipe 20 is connected to the side wall of the feeding pipe 16. A return pipe 21 is installed on the side wall of the water tank 17. The heat exchange pipe 20 and the return pipe 21 are both connected to the inside of the spray chamber 6. A solenoid valve for controlling the water supply of the branch is provided inside the feeding pipe 16. A plurality of heat exchange strips 27 are installed through the upper end of the extrusion plate 22. The heat exchange pipe 20 is a water supply branch pipe. The water pump 18 pumps hot water to form a hot water flow circulation, thereby heating the liquid medicine to be atomized, thereby reducing the low-temperature stimulation of the atomization process, making the atomization process more comfortable, and the water flow can be heated to boiling, and then sprayed out through the main feeding pipe 16, so as to perform high-temperature disinfection and cleaning on the used pipes and areas, so as to facilitate reuse;

[0032] In the present invention, in actual use, the medicine storage box 3 is filled with the required liquid medicine by the medicine filling tube 10, and the electromagnet 14 is controlled to be powered on and off. The electromagnet 14 is powered on to attract the pump medicine ring 121, so that the liquid medicine is extracted through the medicine extraction needle 13, and the amount of the extracted liquid medicine is controlled by the power supply intensity of the electromagnet 14. Under repeated power on and off control, the liquid medicine transfer can be achieved in cooperation with the pump medicine spring 12. The liquid medicine will enter the feeding tube 16 through the transfer tube 15 and then be injected into the mixing chamber 7. The one-way valves in the transfer tube 15 and the feeding tube 16 can ensure that the liquid medicines will not randomly run around during the transfer process, and can ensure that they can enter the mixing chamber 7 smoothly.

[0033] After the liquid medicine reaches the mixing chamber 7, it is in a basically mixed state. Driven by the motor 8, the turntable 9 rotates continuously. Since the upper end surface of the turntable 9 is an inclined surface, the upper and lower positions of the screw 30 and the push rod 25 are constantly changed during the rotation process, thereby completing the reciprocating up and down motion.

[0034] Since the screw 30 is threadedly connected, the up and down movement process will be accompanied by its own rotation, so that the rotating block 31 continuously drives the stirring shaft 34 to rotate, and the stirring shaft 34 drives the stirring rod 35 to fully stir and mix the liquid medicine, thereby improving the overall medication effect;

[0035] The up and down movement of the push rod 25 will push the extrusion plate 22 to move up and down, so that the mixed liquid medicine is extracted through the feeding pipe 29, and then squeezed into the spray pipe 4, so as to achieve effective atomization of the medicine.

[0036] When necessary, the electric heating rod 19 can be started to heat the water in the water tank 17, so that the water temperature inside the water tank 17 increases. Then the water pump 18 pumps the hot water into the spray chamber 6 through the heat exchange tube 20, and the hot water is located between the extrusion plate 22 and the propulsion plate 24, which will not affect the extrusion spray. At the same time, the heat can be transferred through the heat exchange rod to achieve the heating treatment of the atomized liquid medicine, so that the temperature of the atomized liquid medicine is increased, avoiding excessive cold stimulation to the patient and improving the comfort of atomization. The water flow will flow back through the reflux pipe 21 to achieve the circulation heating of hot water.

[0037] When granular medicine is needed, the tablets can be put into the mixing chamber 7 through the medicine adding pipe 37, and then the internal valve of the feeding pipe 29 is closed, so that the liquid medicine and powder medicine in the mixing chamber 7 cannot be transferred. Under the repeated cutting of the cutting blade 36, the tablets will be broken into powder medicine, and then quickly dissolved into the liquid medicine, so that the tablets can also be put into use, so that the scope of medication is improved;

[0038] After the medication is completed, the solenoid valve in the feeding tube 16 can be opened, and high-temperature water flow can be injected into the mixing chamber 7 through the water pump 18, thereby achieving high-temperature cleaning of the mixing chamber 7, the spray chamber 6 and each pipeline, thereby achieving the effect of self-cleaning and disinfection for repeated use.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
