Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a lung clearing and expectoration device for respiratory nursing. Background Art

[0002] At present, respiratory diseases are common diseases in daily life. In the actual treatment process, in addition to relying on drug treatment, respiratory medicine care is also an effective medical method, and expectoration is one of the most important measures in respiratory medicine care. Timely discharge of phlegm in the lungs can avoid the occurrence of other diseases caused by the aggravation of symptoms such as lung infection.

[0003] When using the existing whole-chest oscillation expectoration machine, the inflatable vest needs to be worn on the patient's body. However, some patients have difficulty turning over, and it is not convenient to wear the inflatable vest from under the patient to the patient's back. At the same time, it is not convenient for these patients to tap and expectorate from their backs when they have difficulty turning over. At this time, sputum suction needs to be performed by a sputum suction device. When the negative pressure of the sputum suction device is large, it is easy to cause oxygen supply interruption or negative pressure suction to suck out oxygen-rich gas in the lungs, which may cause hypoxemia. Improper sputum suction operation may damage the mucous membranes in the oral cavity, nasal cavity and airway, causing bleeding. The operation requirements are relatively high, and it is not convenient to tap and oscillate from the patient's back to expectorate the patient when he is lying flat. Summary of the invention

[0028] Preferably: a No. 2 L-shaped groove is provided on the lower end surface of the rotating block, and one end of the No. 2 L-shaped groove passes through the outer surface of the rotating block, a gear ring is fixedly installed on the upper end surface of the rotating block, a motor is fixedly installed on the upper end of the circulation bin, a gear that movably passes through the circulation bin is fixedly installed on the output end of the motor, and the gear is meshed and transmission-connected with the gear ring.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The motor is driven to rotate the rotating block inside the circulation chamber. When one end of the No. 1 L-shaped groove is connected to an air outlet pipe, the air pumped into the main body enters the corresponding air distribution pipe through the No. 1 L-shaped groove, causing the air chamber connected to it to expand. Then the rotating block continues to rotate, so that the No. 1 L-shaped groove is connected to the next air outlet pipe. At this time, the No. 2 L-shaped groove is connected to the first air outlet pipe. The air pump is turned on to discharge the air inside the first row of air chambers to the outside through the No. 2 L-shaped groove, causing the air chamber to shrink. Similarly, with the continuous rotation of the rotating block, multiple rows of air chambers are expanded and contracted in turn, causing the knocking plate to knock upward from the bottom of the patient's back in a specific order to discharge sputum.

[0031] 2. When the air chamber expands, the sliding limit of the sliding sleeve and the sliding rod allows the knocking plate to move up and knock on the air cushion, transmitting the vibration and oscillation generated by knocking on the air cushion to the patient's body, stimulating tissues such as the bronchi and alveoli in the respiratory tract, loosening the sputum, and discharging it from the respiratory tract. When the air chamber contracts, the knocking plate moves down to facilitate the next knock. At the same time, the contraction of the air chamber causes it to deform and be stored as the air bag contracts, reducing its thickness, so that it can be easily inserted into the back of a lying patient.

[0032] 3. When the patient is expectorating on his side, the connecting strips on both sides can be deflected to a certain angle with the airbag. By turning the No. 1 tightening knob against the connecting plate, the deflection angles on both sides of the airbag can be fixed. This makes it easier for the airbag to fit the patient's back when both sides are attached to the patient's back. This improves the vibration transmission effect of the knocking plate to the bottom of the patient's back. When the arc-shaped card plate is clamped inside the rail, the arc-shaped card plate is clamped on the side of the patient's body, and the airbag is suspended and fixed to improve its fixing effect.

[0033] 4. When the airbag is located under the lying patient, rotate the connecting plate and turn the No. 2 fastening knob to insert it into the limiting hole, fix the connecting plate, and make the connecting plate drive the rotatable connecting strip above to support the patient's body, thereby improving the supporting effect of the airbag and making it easier for the knocking component to start working.

[0047] Embodiment 1

[0048] like Figure 3 , Figure 8 and Fig. 9 As shown, in this embodiment, the circulating air intake component 6 includes: a circulating chamber 601 movably arranged on one side of the airbag 201, three air outlet pipes 602, which are fixedly embedded and installed at equal angles on the outer surface of the circulating chamber 601, and a rotating block 604, which is rotatably connected to the inside of the circulating chamber 601; the upper and lower ends of the circulating chamber 601 are fixedly embedded and installed with connectors 603, one connector 603 is fixedly connected to the other connecting hose 101, and the other connector 603 is fixedly connected to the air intake end of the air pump 7 through a pipeline, and the upper surface of the rotating block 604 An L-shaped groove 605 is provided on the surface, and one end of the L-shaped groove 605 passes through the outer surface of the rotating block 604; a second L-shaped groove 606 is provided on the lower end surface of the rotating block 604, and one end of the second L-shaped groove 606 passes through the outer surface of the rotating block 604, a gear ring 607 is fixedly installed on the upper end surface of the rotating block 604, a motor 608 is fixedly installed on the upper end of the circulation bin 601, and a gear 609 that moves through the circulation bin 601 is fixedly installed on the output end of the motor 608, and the gear 609 is meshingly connected with the gear ring 607 for transmission.

[0049] In this embodiment, the motor 608 runs, driving the gear 609 to rotate, and the gear 609 and the ring gear 607 are meshed and driven, so that the ring gear 607 drives the rotating block 604 to rotate inside the circulation chamber 601. When one end of the No. 1 L-shaped groove 605 is connected to an air outlet pipe 602, the air pumped into the oscillating sputum removal machine 1 enters the corresponding air distribution pipe 505 through the No. 1 L-shaped groove 605, so that the air chamber 506 connected thereto expands, and then the rotating block 604 continues to rotate, so that the No. 1 L-shaped groove 605 is connected to the air outlet pipe 602. The L-shaped groove 605 is connected to the next air outlet pipe 602, so that the air bin 506 at the corresponding position expands. At this time, the second L-shaped groove 606 is connected to the first air outlet pipe 602, and the air pump 7 is turned on to discharge the air inside the first row of air bins 506 to the outside through the second L-shaped groove 606, so that the air bin 506 contracts. Similarly, under the continuous rotation of the rotating block 604, multiple rows of air bins 506 are expanded and contracted in turn, so that the knocking plate 504 knocks upward from the bottom of the patient's back in a specific order to discharge sputum.

[0050] like Figure 3 , Figure 6 and Figure 7 As shown, in the present embodiment, a mounting plate No. 101 is fixedly installed on the inner upper surface of the airbag 201 at a position corresponding to the mounting plate No. 207, a sliding bar 502 is symmetrically fixedly installed on the lower surface of the mounting plate No. 101, an air cushion 503 is fixedly installed on the lower surface of the mounting plate No. 101 at the outer side of the sliding bar 502, a sliding sleeve 509 is symmetrically fixedly installed on the outer surface of the knocking plate 504, and the sliding rod 502 slides through the sliding sleeve 509; one side of the multiple air pipes 508 located in the same row is fixedly connected with an air distribution pipe 505, one end of the air distribution pipe 505 is fixedly passed through the airbag 201, and the multiple air distribution pipes 505 are respectively fixedly connected to the air outlet pipes 602 at the corresponding positions.

[0051] During specific implementation, when the air chamber 506 expands, the sliding limit of the sliding sleeve 509 and the sliding rod 502 allows the knocking plate 504 to move up and knock on the air cushion 503, so that the vibration and oscillation generated by knocking on the air cushion 503 are transmitted to the patient's body, stimulating tissues such as the bronchi and alveoli in the respiratory tract, loosening the sputum, and discharging it from the respiratory tract; when the air chamber 506 contracts, the knocking plate 504 moves down to facilitate the next knocking, and at the same time, the contraction of the air chamber 506 causes it to be deformed and stored as the air bag 201 contracts, thereby reducing its thickness and facilitating its penetration into the back of a patient lying flat.

[0052] like Figure 2 , Figure 4 and 5 As shown, in this embodiment, the adjustment component 3 includes: a plurality of connecting strips 301 are equidistantly fixedly installed on the outer surface of the airbag 201, a plurality of No. 1 step rods 302 are respectively fixedly installed on one side surface of the plurality of connecting strips 301, a plurality of connecting plates 303 are respectively connected to the outer sides of two No. 1 step rods 302 located on the same side, a plurality of No. 2 step rods 305 are respectively fixedly installed on one side surface of the plurality of connecting plates 303, and two connecting rods 306 are respectively connected to the outer sides of two adjacent No. 2 step rods 305; No. 1 step holes 304 are symmetrically opened at both ends of one side surface of the connecting plate 303, the No. 1 step rod 302 passes through the No. 1 step hole 304 at the corresponding position, and is rotatably connected to the No. 1 step hole 304, and No. 2 step holes 307 are symmetrically opened at both ends of one side surface of the connecting rod 306, the No. 2 step rod 305 passes through the No. 2 step hole 307 at the corresponding position, and is rotatably connected to the No. 2 step hole 307.

[0053] During specific implementation, when the patient lies sideways to expectorate, after the airbag 201 expands, multiple connecting strips 301 located on the top move upward, and through the rotational connection between the No. 1 step hole 304 and the No. 1 step rod 302, and the rotational connection between the No. 2 step rod 305 and the No. 2 step hole 307, the connecting strips 301 located on both sides can be deflected by a certain angle along with the airbag 201, and by turning the No. 1 fastening knob 4, it is screwed and rotated inside the threaded groove 402 to press against the connecting plate 303, and the deflection angle of both sides of the airbag 201 is fixed, so that when the two sides of the airbag 201 fit the patient's back, the shape of the airbag 201 is fixed, so that it fits the patient's back, thereby improving the vibration transmission effect of the knocking plate 504 when it touches the bottom of the patient's back.

[0054] like Figure 1 and Figure 2 As shown, in this embodiment, a rail 202 is fixedly installed on one side surface of the airbag 201, an arc-shaped clamping plate 203 is slidably inserted inside the rail 202, and a plurality of prismatic shrinkage grooves 204 are opened at equal angles on the inner surface of the arc-shaped clamping plate 203.

[0055] During specific implementation, when the patient lies sideways to expectorate, the arc-shaped card plate 203 is clamped inside the card rail 202. The arc-shaped card plate 203 is elastic and is bent inwardly through the prismatic contraction groove 204. The arc-shaped card plate 203 is clamped on the side of the patient's body, and the airbag 201 is suspended and fixed to improve its fixing effect.

[0056] Embodiment 2

[0057] On the basis of the first embodiment, in order to compensate for the problem that the airbag 201 in the first embodiment expands longitudinally and its deployment height is relatively low, making it inconvenient for the air chamber 506 to deploy.

[0058] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, a limiting hole 308 is provided on one side surface of the two connecting strips 301 located at the bottom, and a threaded groove 402 is symmetrically provided on one side surface of the connecting rod 306, and a No. 1 fastening knob 4 is screwed in and connected inside the threaded groove 402, and a threaded sleeve 403 is fixedly installed at the lower end of the one side surface of the two connecting plates 303 located at the outside, and a No. 2 fastening knob 401 is screwed in and connected inside the threaded sleeve 403, and the No. 2 fastening knob 401 passes through the threaded sleeve 403 and is movably connected to the limiting hole 308.

[0059] During specific implementation, the shape of the airbag 201 is fixed by turning the No. 1 fastening knob 4 to make it fit the patient's back. When the airbag 201 is located under the lying patient, the connecting plate 303 is rotated and the No. 2 fastening knob 401 is turned to insert it into the limiting hole 308 to fix the connecting plate 303. The connecting plate 303 drives the rotatable connecting strip 301 above to support the patient's body, thereby improving the supporting effect of the airbag 201 and at the same time increasing its supporting height to facilitate the operation of the knocking component 5.
