Description

Technical Field

[0001] The invention relates to a medical device, in particular to a breathing trainer. Background Art

[0002] Respiratory trainers are Class I medical devices. Their main users include postoperative respiratory rehabilitation, long-term rehabilitation training for patients with chronic respiratory diseases, and respiratory muscle adaptability training for patients before being taken off the ventilator. Common respiratory trainers have a three-ball structure, that is, three ventilators are set up, and each ventilator is equipped with a small ball that requires different airflows to drive. The small ball is driven by blowing or inhaling air into the ventilator to achieve the purpose of training. This type of respiratory trainer needs to be disassembled and rinsed after use, and then left to dry. It is not convenient to rinse and dry in crowded and compact environments such as hospitals. In response to the actual situation of the outpatient department and inpatient wards in the hospital, our hospital, in conjunction with Zhijian Medical Technology (Tianjin) Co., Ltd., has developed a new set of three-ball respiratory trainers.

[0020] The breathing trainer is the main tool for respiratory rehabilitation training and has a wide range of uses. When using the breathing trainer, the user needs to bite the air nozzle with his mouth and blow air into the breathing trainer or inhale air outward. During the blowing process, the saliva in the mouth will enter the breathing trainer with the air flow, and when inhaling, the odor and harmful microorganisms generated by the long-term use of the breathing trainer will enter the user's body. Although existing breathing trainers are generally equipped with filter cotton on the air nozzle, the filtering effect is very limited, and they need to be thoroughly disassembled and rinsed after each use.

[0021] Aiming at the in-hospital use environment, we optimized the design of the existing three-ball breathing trainer and launched a new three-ball breathing trainer.

[0022] See also Figure 1 The breathing trainer designed by us is similar in appearance to the traditional three-ball breathing trainer, and also uses the three-ball design, which can reduce the mold development cost. Three ventilators 3 are installed between the base 1 and the top plate 2, and the ventilators 3 are connected to the base 1 and the top plate 2 through buckles. The air nozzles 5 are installed on the base 1 and the top plate 2 respectively.

[0023] In order to reduce the amount of saliva carried by the airflow into the ventilation tube 3, the air nozzle 5 and the ventilation passage 4 inside the base 1 and the top plate 2 are redesigned.

[0024] Reference Figure 4 , a mounting groove 13 is specially designed in the air nozzle 5. An arc-shaped guide plate 14 is installed on the side of the mounting groove 13 facing the air flow inlet, and a pressure plate 16 is installed on the side of the mounting groove 13 facing the air flow inlet. The pressure plate 16 is connected to the mounting groove 13 through a torsion spring 15. The air flow flows in from the top of the side wall of the air inlet end of the mounting groove 13 and flows out from the bottom of the side wall of the air outlet end of the mounting groove 13. The filter cotton 6 is located in the mounting groove 13, and the pressure plate 16 squeezes the filter cotton 6. When inhaling or blowing, the pressure plate 16 reduces the squeezing of the filter cotton 6 under the push of the air flow, so that the filter cotton 6 expands and absorbs saliva efficiently. When the inhalation or blowing ends, the pressure plate 16 squeezes the filter cotton 6 again under the action of the torsion spring 15, so that the saliva and other moisture substances absorbed by the filter cotton 6 seep downward, thereby improving the adsorption efficiency of the filter cotton 6 during the next adsorption. By opening a hole (ie, the second through hole 16 - 1 ) on the pressing plate 16 , the resistance of the pressing plate 16 to the airflow flowing through the upper part of the filter cotton 6 can be reduced.

[0025] Reference Figure 5We installed an adsorption sheet 7 composed of a substrate 7-1, a desiccant layer 7-2 and an activated carbon layer 7-3 and a matching baffle 18 in the ventilation passage 4. When the airflow passes through the ventilation passage 4, the adsorption sheet 7 performs secondary adsorption on the odor and moisture in the airflow. The baffle 18 is used to form a flow trend of the airflow circulating toward the adsorption sheet 7, and the through groove 19 can reduce the turbulence in the area between the baffle 18 and the inner wall of the ventilation passage 4, thereby improving the smoothness of the airflow in the ventilation passage 4.

[0026] After the airflow has been subjected to the above two highly efficient adsorptions, most of the saliva and other substances carried by the airflow are removed, thereby effectively keeping the inside of the ventilator 3 clean.

[0027] Reference Figure 6 When designing the adsorption sheet 7, in order to make full use of the downward airflow generated by the baffle 18, the substrate 7-1 and the desiccant layer 7-2 are exactly the same in shape and size and are completely pasted together, while the length of the activated carbon layer 7-3 (the activated carbon layer is a flexible layer) is the same as the former two, but the width is larger, and only the two long sides of the activated carbon layer 7-3 are pasted to the long sides of the desiccant layer 7-2, and its short sides and interior are not pasted to the desiccant layer 7-2. In this way, under the combined action of the airflow parallel to the adsorption sheet 7 and the airflow directed toward the adsorption sheet 7 through the baffle 18, a local circulation flow area will be formed on the upper and lower surfaces of the activated carbon layer 7-3, effectively improving the adsorption effect of the activated carbon 7-3.

[0028] For a frequently used breathing trainer, it is not possible to keep the inside of the ventilator 3 clean for a long time just by filtering and adsorption. Therefore, we designed a cleaning rod for use with the breathing trainer. Figure 2 The cleaning rod comprises a connecting rod 10 with a cleaning head 11 installed on the side, the connecting rod 10 can be inserted into the ventilator 3 through the first through hole 8, the cleaning head 11 cleans the side wall of the ventilator 3, and the arc-shaped cleaning piece 12 at the bottom of the connecting rod 10 is used to clean the small ball. The cleaning rod can not only conveniently clean the inside of the ventilator 3, but also be used to adjust the lifting damping of the small ball (not shown in the figure) in the ventilator 3.

[0029] Reference Figure 3 The top of the arc-shaped cleaning sheet 12 is connected to the threaded rod 21 through a spring 22, and the threaded rod 21 is screwed into the threaded hole 20 on the connecting rod 10. Figure 2When cleaning, the arc-shaped cleaning sheet 12 is rotated outward to increase the length of the entire cleaning rod. The connecting rod 10 is held and rotated, and the cleaning head 11 cleans the side wall of the ventilator 3. The lower surface of the arc-shaped cleaning sheet 12 contacts the ball. As the arc-shaped cleaning sheet 12 rotates, the spiral stripes rub against the ball, driving the ball to rotate, thereby achieving comprehensive cleaning of the surface of the ball. When it is necessary to increase the lifting damping of the ball, the length of the entire cleaning rod is shortened, the cleaning rod is placed in the ventilator 3, and the top cover 9 is covered. The top of the connecting rod 10 contacts the bottom surface of the top cover 9 to limit the entire cleaning rod. When the airflow drives the ball to rise and contacts the arc-shaped cleaning sheet 12, the spring 22 applies additional elastic damping to the ball.

[0030] We also installed a rubber damping sleeve 23 at the bottom end of the threaded rod 21. The rubber damping sleeve 23 is located on the outside of the spring 22. By installing different numbers of retaining rings 24 on the outside of the rubber damping sleeve 23 and adjusting the tightness of each retaining ring 24, the rubber damping sleeve 23 can adjust the damping of the spring 22 in a differentiated and timed manner.

[0031] The breathing trainer provided by the present invention only needs to replace the filter cotton 6 and the adsorption sheet 7 and rinse the air nozzle 5 after each use. After using it for about 5-8 times, use the cleaning rod to clean the ventilator 3. When it is used for more than 15 days or before being stopped for a long time, it is completely disassembled, rinsed and dried. Compared with traditional breathing trainers, the cleaning complexity after use is greatly simplified, and the cleaning rod can also be used to expand the training damping range provided by the breathing trainer.
