Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an in-depth and precise drug delivery device and a drug delivery method for respiratory medicine. Background Art

[0002] Respiratory diseases are common and frequently occurring diseases. The main lesions are in the trachea, bronchi, lungs and chest cavity. Mild lesions often cause coughing, chest pain and respiratory impairment. Severe lesions cause dyspnea, hypoxia and even respiratory failure leading to death. Respiratory drug administration can act directly on the affected area and is a common treatment method in the respiratory department. In order to prevent the drug delivery nozzle from being contaminated, the invention with application number 2022104865838 discloses a deep and precise drug delivery device for respiratory medicine, including a catheter, one end of which is fixedly installed with a bite airbag, the other end of which is fixedly installed with a fixed airbag, and an inner airbag is arranged inside the fixed airbag; the present invention arranges an inflatable fixed airbag so that the fixed airbag is extended into the patient's process. During the drug delivery process, the depth of entry into the oral cavity cannot be determined in advance, which causes the position reached by the drug delivery nozzle to easily deviate from the affected area, resulting in poor drug delivery accuracy. In addition, there is mucus in the respiratory tract to protect the respiratory tract. Due to the obstruction of the mucus, the liquid medicine cannot directly contact the affected area, and the treatment effect is limited. Therefore, it is necessary to propose a deep and precise drug delivery device for respiratory medicine with a positioning function. Summary of the invention

[0006] Preferably, the inner diameters of the positioning sleeve, the rubber ring and the threaded ring are consistent.

[0007] Preferably, the purpose is to remove mucus from the inner wall of the trachea so that the medicine can directly act on the affected area. The drug delivery mechanism includes a guide cylinder, a groove, a scraper, a hollow cylinder, a sleeve, a guide column, a spring and a connecting tube. The guide cylinder is fixedly connected to the left end of the throat, and the outer wall of the guide cylinder is provided with two grooves opposite to each other in front and back; there are two scrapers, which are inserted into the outer wall of the guide cylinder opposite to each other up and down; the hollow cylinder is horizontally installed at the center position of the right inner wall of the guide cylinder, and the hollow cylinder is connected to the drainage tube; the sleeve is slidably sleeved on the outer wall of the hollow cylinder, and the right side wall of the sleeve is connected to the pull rope; there are two guide columns, which are installed on the outer wall of the sleeve opposite to each other up and down, and the guide column is inserted into the inner cavity of the scraper; the spring is sleeved on the outer wall of the hollow cylinder, and the sleeve is pushed to move left under the action of the spring elastic force; one end of the connecting tube is installed in the inner cavity of the groove, and the other end is connected to the hollow cylinder.

[0008] Preferably, the outer side of the scraper is in an arc shape.

[0009] Preferably, the guide pillars are obliquely distributed on the outer wall of the sliding sleeve.

[0010] The drug delivery method based on the in-depth precision drug delivery device used in respiratory medicine includes the following steps: Step 1: According to the diseased part and depth of the patient's respiratory tract, pull the baffle to move left and right, measure the insertion depth of the guide tube according to the length unit on the scale, turn the threaded ring clockwise to move the threaded ring to the left and squeeze the rubber ring, the rubber ring is deformed by pressure, and expands inward until it is pressed against the outer wall of the throat, position the baffle, and extend the guide tube into the human throat. When the baffle contacts the human face, the groove reaches the diseased part; Step 2: Before administering the medicine, pull the pull ring to allow the pull rope to pull the sliding sleeve to move rightward along the outer wall of the hollow cylinder. The inclined surface of the guide column squeezes the scraper outward, and the scraper contacts the patient's diseased part, driving the guide cylinder to rotate.

The present invention can pull the pull ring to make the pull rope pull the sliding sleeve to move right, and the inclined surface of the guide column squeezes the scraper outward to make the scraper contact with the inner wall of the throat or trachea. The scraper rotates to scrape off the mucus, thereby removing the mucus and exposing the affected area. Then, the drug is administered, so that the drug solution acts directly on the affected area, thereby improving the treatment effect. BRIEF DESCRIPTION OF THE DRAWINGS
