Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically refers to an atomization device for a western medicine pharmacy. Background Art

[0002] Nebulizer inhalation therapy is an important and effective treatment method for respiratory diseases. This treatment method uses a medical nebulizer device to atomize the drug solution into a liquid mist consisting of a number of tiny liquid droplets. The patient inhales the liquid mist through breathing and deposits it into the lungs, thereby achieving the purpose of painless, rapid and effective treatment.

[0003] The existing disposable nebulizer inhaler uses the gas jet principle and the Venturi principle to compress air or oxygen through a small tube to form a high-speed airflow, which drives the liquid to be sprayed onto the obstacle to form fine mist particles. The uncontrollable direction of the drug splashing causes the mist particles to merge with each other or splash onto the tube wall to form water droplets, resulting in low drug atomization efficiency. Because the drug atomization process is at the bottom of the atomization device, after the atomization is completed, there will still be splashed drugs on the inner wall and bottom of the atomizer, which has the defect of wasting drugs. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an atomization device for a western medicine pharmacy, which effectively solves the above problems.

[0005] The technical solution adopted by the utility model is as follows: the utility model proposes an atomization device for a western medicine pharmacy, comprising an atomization device, a mask and an air pump, wherein the atomization device is connected to the air pump, and the mask is connected to the atomization device; the atomization device comprises an airflow tube, a medicine liquid tube and a medicine liquid dropper, wherein the medicine liquid tube is connected to the airflow tube, and the medicine liquid dropper is arranged in the medicine liquid tube; a protective shell is arranged outside the atomization device, and a handle is arranged at the bottom of the protective shell.

[0006] Furthermore, the air flow pipe is provided with an air inlet pipe, an air outlet pipe and a compression pipe, and the compression pipe is arranged between the air inlet pipe and the air outlet pipe.

[0007] Furthermore, an air inlet is provided on the air inlet pipe, a recovery tank and a reflux pipe are provided at the bottom of the air outlet pipe, and a nozzle is provided inside the compression pipe. The air flow flows into the air inlet pipe from the air inlet, passes through the compression pipe, is ejected from the nozzle, and enters the air outlet pipe.

[0008] Furthermore, a capillary is provided at the bottom of the medicine liquid tube, the capillary is connected to the center of the compression tube, a reflux hole column is provided on the side wall of the medicine liquid tube, and the reflux tube is connected to the reflux hole column.

[0009] Furthermore, a retaining ring is provided on the inner wall of the medicine liquid tube, the medicine liquid dripper is provided on the retaining ring, and a sealing cover is provided on the top of the medicine liquid tube.

[0010] Furthermore, a side groove ring is provided on the outer side of the top of the medicine dripper, a dropper is provided on the bottom of the medicine dripper, a reflux groove is provided on the side groove ring, and the reflux hole column is arranged in the reflux groove. The atomized medicine is added into the medicine dripper, and the atomized medicine slowly drips from the dropper to the bottom of the medicine tube.

[0011] Furthermore, the mask is provided with a connecting tube, the connecting tube is connected to the exhaust pipe, and breathing holes are provided on both sides of the mask, and the patient performs atomization treatment by wearing the mask.

[0012] Furthermore, the air pump is provided with a hose, a trachea plug is provided at the end of the hose, and the trachea plug is arranged in the air inlet.

[0013] The beneficial effects achieved by the utility model using the above structure are as follows:

[0014] 1. The airflow is compressed through the compression tube. The airflow flowing through the compression tube will drive the liquid medicine in the capillary tube to flow into the compression tube. The liquid medicine flows through the nozzle and is atomized under the impact of the high-pressure airflow, which greatly improves the atomization efficiency.

[0015] 2. The medicine liquid is stored in the medicine dripper and dripped drop by drop into the bottom of the medicine liquid tube to prevent excessive accumulation of medicine liquid at the bottom of the medicine liquid tube, causing the capillary to continuously add medicine liquid to the compression tube, reducing the impact effect of the high-pressure airflow, causing large particles of water droplets to condense, thereby reducing the atomization effect of the medicine liquid.

[0016] 2. A small amount of atomized droplets that cannot be lifted by the airflow will drip into the recovery tank at the bottom of the outlet pipe and flow into the medicine pipe along with the airflow. The medicine flows along the reflux hole column into the medicine dropper. At the same time, under the action of the airflow, the tiny droplets attached to the surface of the outlet pipe will be vaporized and inhaled into the respiratory tract by the patient, greatly reducing the residual medicine in the outlet pipe.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 6 As shown, the utility model proposes an atomization device for a western medicine pharmacy, comprising an atomization device 1, a mask 2 and an air pump 3, wherein the atomization device 1 is connected to the air pump 3, and the mask 2 is connected to the atomization device 1; the atomization device 1 comprises an airflow tube 11, a medicine liquid tube 12 and a medicine liquid dropper 13, wherein the medicine liquid tube 12 is connected to the airflow tube 11, and the medicine liquid dropper 13 is arranged in the medicine liquid tube 12; a protective shell 14 is arranged outside the atomization device 1, and a handle 141 is arranged at the bottom of the protective shell 14.

[0027] The air flow pipe 11 is provided with an air inlet pipe 111 , an air outlet pipe 112 and a compression pipe 113 . The compression pipe 113 is provided between the air inlet pipe 111 and the air outlet pipe 112 .

[0028] An air inlet 114 is provided on the air inlet pipe 111 , a recovery tank 115 and a reflux pipe 116 are provided at the bottom of the air outlet pipe 112 , and a nozzle 117 is provided inside the compression pipe 113 .

[0029] A capillary 121 is provided at the bottom of the liquid medicine tube 12 , and the capillary 121 is connected to the center of the compression tube 113 . A reflux hole column 122 is provided on the side wall of the liquid medicine tube 12 , and the reflux tube 116 is connected to the reflux hole column 122 .

[0030] A retaining ring 124 is disposed on the inner wall of the liquid medicine tube 12 , the liquid medicine dripper 13 is disposed on the retaining ring 124 , and a sealing cover 123 is disposed on the top of the liquid medicine tube 12 .

[0031] A side groove ring 131 is provided on the top of the liquid medicine dripper 13 , a dropper 132 is provided on the bottom of the liquid medicine dripper 13 , a reflux groove 133 is provided on the side groove ring 131 , and the reflux hole column 122 is provided in the reflux groove 133 .

[0032] The mask 2 is provided with a connecting pipe 21 , which is connected to the air outlet pipe 112 , and breathing holes 22 are provided on both sides of the mask 2 .

[0033] The air pump 3 is provided with a hose 31 , and an air pipe plug 32 is provided at the end of the hose 31 . The air pipe plug 32 is arranged in the air inlet 114 .

[0034] During specific use, the connecting tube 21 of the mask 2 is inserted into the air outlet pipe 112 of the atomizing device 1, the tracheal plug 32 is inserted into the air inlet 114, the air pump 3 is turned on, and the high-pressure gas flows into the air inlet pipe 111 from the hose 31, and flows out from the air outlet pipe 112 through the compression tube 113. The patient wears the mask 2 on the mouth and nose, the doctor opens the sealing cover 123 on the top of the medicine tube 12, adds the atomized medicine into the medicine dropper 13, and covers the sealing cover 123.

[0035] The atomized medicine in the medicine dripper 13 drops drop by drop from the dropper 132 to the bottom of the medicine tube 12, and flows through the compression tube 113 with the high-pressure gas. According to the Bernoulli principle, the pressure is small where the flow rate is large, so that there is a pressure difference between the capillary 121 and the compression tube 113, so that the medicine at the bottom of the medicine tube 12 flows into the compression tube 113 through the capillary 121, and the medicine passes through the nozzle 117, is atomized under the impact of the high-pressure airflow, and enters the mask 2 along the outlet pipe 112 to be breathed by the patient.

[0036] When the air flow flows from the compression tube 113 into the air outlet pipe 112, the volume suddenly increases, resulting in a sudden drop in pressure, which in turn reduces the air flow. A small amount of atomized droplets that cannot be lifted by the air flow will drip into the recovery tank 115 at the bottom of the air outlet pipe 112. Since the gas capillary 121 inside the medicine liquid tube 12 enters the compression tube 113, a negative pressure is formed in the medicine liquid tube 12. The air flow in the air outlet pipe 112 will be replenished into the medicine liquid tube 12 through the reflux tube 116. The droplets that drip into the recovery tank 115 flow into the medicine liquid tube 12 along with the air flow. The medicine liquid flows into the medicine liquid dropper 13 along the reflux hole column 122. Because there is continuous air flow in the air outlet pipe 112, under the action of the air flow, the tiny droplets attached to the surface of the air outlet pipe 112 will quickly evaporate and vaporize under the action of the air flow, and be inhaled into the respiratory tract by the patient, which greatly reduces the residual medicine liquid in the air outlet pipe 112 and improves the atomization efficiency of the medicine liquid.
