Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, specifically a lung function testing trainer. Background Technology
[0002] The pulmonary function test procedure requires a high level of skill from the patient, who must exert force and blow air with maximum force and maintain continuous blowing.
[0003] Pulmonary function tests are difficult even for adult patients, and even more so for pediatric patients. Therefore, the following problems may arise during clinical examinations:
[0004] Technicians need to spend a lot of time verbally explaining the examination process (what the patient should do) in the early stages; young children are inherently less attentive and less compliant than adults, and cannot get into the state quickly, which leads to resistance, crying and fussing, direct rejection of the examination, making it impossible to continue smoothly, or even giving up the examination altogether.
[0005] Currently, there is a lack of a simulator that allows for advance training in lung function testing, including rapid and sustained blowing exercises. Utility Model Content
[0006] In view of the problems existing in the prior art, this utility model provides a lung function test simulation trainer to solve at least one of the above technical problems.
[0007] To achieve the above objectives, this utility model provides a lung function test simulator, including a mouthpiece, characterized in that it further includes a training trachea, the front end of which is detachably connected to the mouthpiece.
[0008] The training air tube includes a horizontally arranged air chamber, which includes an air blowing chamber and an air inhalation chamber arranged side by side. The air blowing chamber and the air inhalation chamber are separated by a brass plate, and the brass plate has a left air hole and a right air hole arranged side by side.
[0009] The upper end of the upper tone reed is riveted to the upper part of the brass plate. The upper tone reed is located in the air blowing chamber and is positioned above the left air hole.
[0010] The front end of the lower sound reed is riveted to the bottom of the brass plate. The lower sound reed is located in the air intake chamber and is positioned below the right air hole.
[0011] It also includes an air blowing tube, the bottom of which is connected to the rear end of the air blowing chamber. The bottom of the air blowing tube is provided with a breathable screen, and a hollow plastic ball is slidably disposed inside the air blowing tube.
[0012] This invention enables training that involves rapid and continuous blowing.
[0013] This invention uses continuous inhalation to maintain the vibration of the lower reed in the inhalation chamber, producing sound under the influence of airflow. The sound output from the inhalation chamber determines whether the patient is in an inhalation state. Similarly, continuous exhalation maintains the vibration of the upper reed in the exhalation chamber, producing sound under the influence of airflow. The sound output from the exhalation chamber determines whether the user is in an exhalation state. Users can train by maintaining continuous blowing to a set desired height using the hollow plastic ball. Users can also train by rapidly blowing air through the hollow plastic ball to maintain sustained blowing.
[0014] This device facilitates users' breathing training.
[0015] More preferably, the air blowing tube includes a transparent plastic air tube with openings at the top and bottom, and a calibration tube is slidably connected to the outer wall of the transparent plastic air tube.
[0016] It facilitates determining the required air-blowing height of the hollow sphere using a calibration tube.
[0017] More preferably, the calibration tube includes an upper ring body and a lower ring body arranged vertically, the upper ring body and the lower ring body are connected by a connecting part, and a locking screw that abuts against the transparent plastic vent tube is threaded onto the connecting part.
[0018] The area between the upper and lower rings makes it easy to determine the height range of the hollow sphere when it is inflated.
[0019] More preferably, the top of the transparent plastic vent tube is detachably connected to a vent cap.
[0020] More preferably, a pair of interfaces are provided at the top of the rear end of the air blowing chamber;
[0021] It also includes a blasting air training tube, which is interchangeably installed with the air tube at the interface;
[0022] The explosive blowing training tube includes a corrugated tube and a transparent tube arranged at the top and bottom, and the top of the corrugated tube is sealed.
[0023] Initially, the bellows is compressed. A rapid, forceful breath from the user can extend and expand the bellows. This allows the user to gauge the force of their breath by observing whether the bellows expands.
[0024] More preferably, a timer is detachably mounted on the training trachea.
[0025] It facilitates the recording of the duration of the breath-holding action.
[0026] Beneficial effects:
[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0028] This invention enables rapid blowing training through a burst-blowing training tube, and training in maintaining the blown air position through the tube. The training involves vocalizing the blowing and inhaling sounds through the training tube, thus training in both blowing and exhaling. Attached Figure Description

[0035] See Figures 1 to 2Specific Embodiment 1: A lung function test simulator includes a mouthpiece and a training trachea. The front end of the training trachea is detachably connected to the mouthpiece 13. The training trachea includes a horizontally arranged air chamber, which includes an inhalation chamber 1 and an inhalation chamber 2 arranged side by side. The inhalation chamber 1 and the inhalation chamber 2 are separated by a brass plate 3. The brass plate 3 has a left air hole and a right air hole arranged side by side. The rear end of an upper reed 4 is riveted to the upper part of the brass plate 3. The upper reed 4 is located in the inhalation chamber 1 and is positioned above the left air hole. The front end of a lower reed 5 is riveted to the lower part of the brass plate 3. The lower reed 5 is located in the inhalation chamber 2 and is positioned below the right air hole. The simulator also includes an inhalation tube 6. The bottom of the inhalation tube 6 is connected to the rear end of the inhalation chamber 1. A breathable screen 12 is provided at the bottom of the inhalation tube 6. A hollow plastic ball 7 is slidably arranged inside the inhalation tube 6. This invention uses continuous inhalation to maintain the vibration of the lower reed 5 within the inhalation chamber 2, producing sound under the influence of airflow. The sound output of the inhalation chamber 2 determines whether the patient is inhaling. Similarly, continuous exhalation maintains the vibration of the upper reed 4 within the exhalation chamber 1, producing sound under the influence of airflow. The sound output of the exhalation chamber 1 determines whether the user is exhaling. The user trains by holding the hollow plastic ball 7 at a predetermined height while exhaling, allowing for rapid and sustained exhalation. This device facilitates exhalation training for users.
[0036] The air-blowing chamber 1 is divided into at least two air-blowing sub-chambers arranged from left to right by a vertically arranged upper partition plate. At least one air-blowing sub-chamber is equipped with an upper tone reed. The air-blowing sub-chambers are connected to the air-blowing pipe.
