Description

Technical Field

[0001] This application relates to the field of medical assistive device technology, and in particular to a simple lung function training device. Background Technology

[0002] The number of elderly people hospitalized due to type II respiratory failure is increasing. Conscious patients have poor tolerance to non-invasive masks, and simple bedside lung function exercises have become an important way to eliminate carbon dioxide. In clinical practice, patients are often asked to blow bubbles in a cup of water through a straw. However, patients with poor cooperation often inhale backward, causing water to be sucked into their mouths and throats, resulting in choking.

[0003] Therefore, it is necessary to propose an exercise device that prevents choking on water during lung exercises. Utility Model Content

[0004] To address or partially address the problems existing in the related technologies, this application provides a simple lung function training device that can prevent patients from inhaling water into their mouths during lung exercises.

[0005] This application provides a simple lung function training device, including: an air blowing unit and a flow unit;

[0006] The air blowing unit includes an extension tube, an air blowing tube is inserted into the extension tube, a tube sleeve is fixedly fitted on the outer periphery of the top of the air blowing tube, the tube sleeve has a sleeve interface, and the sleeve interface is fitted onto the top of the extension tube.

[0007] The flow unit is disposed on the inner wall of the air blowing pipe. The flow unit includes a main flow channel formed on the inner wall of the air blowing pipe and extending along the axial direction of the air blowing pipe. A branch flow mechanism is formed on the side of the main flow channel. The branch flow mechanism includes a branch flow channel. One end of the branch flow channel has an arc-shaped slot, and the other end of the branch flow channel has a direct flow slot. Both the arc-shaped slot and the direct flow slot are connected to the main flow channel. The arc-shaped slot is located above the direct flow slot.

[0008] Furthermore, the main flow channel is multiple, and these main flow channels are circumferentially spaced apart; multiple branch channels are spaced apart vertically on the left and right sides of each main flow channel. That is, the flow unit has multiple branches spaced apart circumferentially on the inner wall of the air blowing pipe, and each main flow channel has multiple branch channels spaced apart vertically on the left and right sides, thereby further increasing the resistance when the water flows upward.

[0009] Furthermore, the main channel extends vertically through the air blowing pipe, facilitating processing and increasing the upward flow path of the water.

[0010] Furthermore, the lower end of the blowing tube is located inside the extension tube and above the lower end of the extension tube. This way, during inhalation, water first flows upwards into the larger extension tube before entering the blowing tube. The different resistances the extension tube and the blowing tube offer to the upward-flowing water create a jerky sensation for the patient.

[0011] Furthermore, there is a gap between the outer wall of the air blowing tube and the inner wall of the extension tube.

[0012] Furthermore, the sleeve has a downward-facing annular groove, the opening at the lower end of which is the sleeve interface, and the annular groove is fitted onto the upper end of the extension tube. The outer wall of the air blowing tube is fixedly connected to the inner wall of the sleeve.

[0013] Furthermore, the lower end of the extension pipe is used to extend into the water body. When the water body moves from bottom to top along the main channel, it enters the tributary channel through the direct current channel and flows into the main channel through the arc-shaped channel. The arc-shaped channel is configured to allow the water body to flow into the main channel obliquely downward.

[0014] Furthermore, the main channel and the tributary mechanism have the same opening depth.

[0015] Furthermore, the sleeve is made of rubber material.

[0016] Furthermore, the inner diameter of the air blowing pipe gradually decreases from top to bottom.

[0017] The technical solution provided in this application can include the following beneficial effects: When in use, the blowing tube is inserted into the extension tube, and then the sleeve is connected to the extension tube through the sleeve interface, so that the blowing tube and the extension tube are connected together. The patient blows air into the extension tube by holding the sleeve part in his mouth, and the air enters the water body through the blowing tube, and then enters the water body through the extension tube to practice blowing bubbles; When the patient inhales, the water body moves upward along the main channel and flows into the branch channel from the direct channel opening. After passing through the branch channel, it flows diagonally downward into the main channel from the arc-shaped opening along its arc angle. When the water body flowing out of the arc-shaped opening mixes with the water body in the main channel, it will form a vortex, resulting in energy loss. The water body loses a lot of energy and has a large pressure drop due to fluid diversion, turning, backflow and convergence in the flow unit, which effectively prevents water body from being inhaled into the mouth during inhalation.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown in the figure, this application provides a simple pulmonary function training device, including an air blowing unit 100 and a flow unit 200. The air blowing unit 100 includes an extension tube 110 that is hollowly arranged for insertion into water. An air blowing tube 120 is inserted and connected to the top of the extension tube 110. A sleeve 121 is fixedly fitted onto the top of the air blowing tube 120. The outer diameter of the lower end of the air blowing tube 120 is smaller than the inner diameter of the extension tube 110, and the outer diameter of the sleeve 121 is larger than the outer diameter of the upper end of the extension tube 110. A sleeve interface 1211 is opened at the bottom of the sleeve 121, and the sleeve interface 1211 is sleeved with the upper end of the extension tube 110. The sleeve 121 has an annular groove with its opening facing downwards. The opening at the lower end of the annular groove is the sleeve interface 1211, and the annular groove is fitted onto the upper end of the extension tube 110.

[0031] Insert the air blowing pipe 120 into the extension pipe 110, and then install the sleeve 121 onto the extension pipe 110 through the sleeve interface 1211. This connects the air blowing pipe 120 and the extension pipe 110, effectively maintaining the stable installation of the air blowing unit 100 and allowing the gas in the air blowing pipe 120 to flow downwards and enter the water body through the extension pipe 110 to blow bubbles. However, because the diameters of the air blowing pipe 120 and the extension pipe 110 are different and they are not sealed, there is a gap between the inner walls of the air blowing pipe 120 and the extension pipe 110. This further results in a lower internal pressure after the air blowing pipe 120 and the extension pipe 110 are connected, which is insufficient to draw up the liquid.

[0032] See Figure 1-4In a further preferred embodiment, the flow unit 200 includes a main flow channel 210 vertically disposed on the inner wall of the air blowing pipe 120. A branch flow mechanism 220 is disposed on the side of the main flow channel 210. The main flow channel 210 and the branch flow mechanism 220 are disposed at the same depth. The branch flow mechanism 220 includes a branch flow channel 221. One end of the branch flow channel 221 has an arc-shaped slot 2211, and the other end of the branch flow channel 221 away from the arc-shaped slot 2211 has a direct flow slot 2212. Both the arc-shaped slot 2211 and the direct flow slot 2212 are connected to the main flow channel 210, and the arc-shaped slot 2211 is located above the direct flow slot 2212.

[0033] See Figure 2 and Figure 3 In a preferred embodiment, multiple flow units 200 are provided on the inner wall of the air blowing pipe 120, and the multiple flow units 200 are arranged evenly in a circumferential direction. The function of the flow units 200 is similar to that of a one-way valve, such as a Tesla valve. Multiple branch channels 221 are provided on the left and right sides of the main flow channel 210 at intervals along the vertical direction to further increase the resistance.

[0034] By setting up several flow units 200, the inner wall of the air blowing pipe 120 has more flow channels, which can make the water pressure drop change larger and make it less likely to form a closed pressure, further preventing liquid from being sucked into the air blowing pipe 120.

[0035] In use, insert the air blowing tube 120 into the extension tube 110, and then connect the sleeve 121 to the upper end of the extension tube 110 through the sleeve interface 1211, thus connecting the air blowing tube 120 and the extension tube 110 together. Submerge the lower end of the extension tube 110 into the water, and have the patient hold the sleeve 121 in their mouth and blow air. The air will then pass through the air blowing tube 120 into the extension tube 110, and then into the water from the extension tube 110 for bubble blowing practice. When the patient inhales, the water flows along the main channel 220 towards... When moving upwards, the water flows into the branch channel 221 from the direct channel 2212. After passing through the branch channel 221, it flows diagonally downwards into the main channel 210 from the arc-shaped channel 2211 along its arc angle. When the water flowing out of the arc-shaped channel 2211 mixes with the water in the main channel 210, it will form a vortex, resulting in energy loss. The water will lose a lot of energy and experience a large pressure drop after passing through the fluid diversion, turning, backflow and convergence in the flow unit 200. This effectively prevents water from being sucked into the mouth during air intake.
