Description

Technical Field

[0001] This invention relates to a medical device, specifically a combined suction-assisted back-percussion mechanism and a nursing device for preventing hypostatic pneumonia. Background Technology

[0002] Hypostatic pneumonia is common in patients who are bedridden for a long time. Due to factors such as advanced age, prolonged bed rest, artificial airway, surgical incision pain, and primary diseases, respiratory secretions cannot be coughed up in a timely and complete manner, which can block small and medium airways and induce lung infections of varying degrees.

[0003] Nursing care for hypostatic pneumonia often involves measures such as back percussion, deep breathing, and effective coughing to promote sputum expectoration, which is the most important measure in treating hypostatic pneumonia. The patient should be kept in a semi-reclining position, and the caregiver should gently pat their back to promote sputum expectoration, thus promoting recovery from hypostatic pneumonia. Back percussion is a physical therapy that promotes sputum expectoration. The percussion points are on both sides of the back, that is, on both sides of the spine, corresponding to the two lobes of the lungs. When percussing, avoid percussing along the middle of the spine to avoid injury. When percussing, the palm should be cupped and the percussion should be performed from bottom to top to vibrate the sputum, making it easier to expel. Back percussion also uses chest wall vibration to dislodge secretions attached to the lungs and bronchi, allowing them to reach the bronchioles through postural drainage and be expelled through coughing.

[0004] When tapping, the hand should be held in a fixed position with the back of the hand raised and the palm hollow, with the fingers bent and the thumb close to the index finger. Tap rhythmically from the bottom of the lung upwards and from the outside in, using the strength of the wrist joint to tap the lesion site from the periphery towards the hilum of the lung in a rhythmic and even manner. From a physics perspective, the faster the frequency, the easier it is for an object placed on an elastic surface to fall. When tapping, older patients can be instructed to take a deep breath and cough forcefully. For elderly patients who are weak and lack strength, and who have phlegm but are unable to breathe, assisted breathing should be provided to avoid difficulty breathing or difficulty breathing when coughing. In addition, the trachea in the suprasternal notch can be pressed to stimulate expectoration.

[0005] Currently, when assisting with coughing and expectoration in the nursing care of patients with hypostatic pneumonia, it is often necessary to rely on medical staff or caregivers to help with back percussion while simultaneously providing oxygen to the patient, which is very inconvenient.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0053] Please see Figures 1-16 As an embodiment of the present invention, the suction-assisted back-tapping integrated mechanism includes two parallel side fixing parts 1 for engaging with the two sides of the hospital bed, and an adjusting arm 2 is rotatably installed at the end of each side fixing part 1.

[0054] A support structure is provided between the two sides of the adjustment arms 2, and a clamping structure is provided between the two sides of the side fixing parts 1. The support structure can connect the two sides of the adjustment arms 2, so that when one side of the adjustment arm 2 is flipped, it can drive the other side of the adjustment arm 2 to flip synchronously. The support structure can also support the patient's back, helping the patient to sit or lie down.

[0055] The clamping structure allows the side fixing parts 1 on both sides to move closer or further apart, so that the mechanism can be installed on the outer edge of the side bed frame of the hospital bed, or removed from the side bed frame of the hospital bed.

[0056] The supporting structure includes a load-bearing component 3 fixedly installed on the inner side of the adjusting arm 2, a connecting component 6 connecting the load-bearing components 3 on both sides of the adjusting arm 2, a sliding component 4 slidably installed on the load-bearing components 3 on both sides, and a flexible component 5 fitted on the sliding component 4.

[0057] Specifically, please refer to Figure 5 and Figure 6 The load-bearing members 3 on both sides are provided with grooves, and the connecting member 6 is set in the grooves on the load-bearing members 3 on both sides. The connecting member 6 is provided with a first protrusion 7 on both sides of its end, and a first groove 8 is provided on the inner wall of the groove for sliding engagement with the first protrusion 7.

[0058] In addition, a second groove 10 is provided on the inner wall of the sliding member 4, and a second protrusion 9 is provided at the end of the load-bearing member 3.

[0059] It should be noted that the first groove 8 does not penetrate the inner wall of the groove, and the second groove 10 does not penetrate the inner wall of the slider 4.

[0060] By connecting the load-bearing components 3 on both sides with the connecting piece 6, the adjusting arms 2 on both sides can be rotated synchronously, and the connection strength between the load-bearing components 3 on both sides can be further improved by using the sliding piece 4.

[0061] The first groove 8 and the first protrusion 7 work together to allow the adjusting arms 2 on both sides and the side fixing parts 1 to move closer or further apart, adapting to hospital beds of different widths. The first protrusion 7 works with the first groove 8, the second protrusion 9 and the second groove 10 to prevent the load-bearing parts 3 on both sides from separating, keeping the side fixing parts 1 and the adjusting arms 2 on both sides as a whole.

[0062] When in use, the patient's back can rest on the sliding member 4 when sitting or lying down. The upper part of the patient's body is supported by the connecting member 6 and the load-bearing members 3 on both sides. At the same time, the soft member 5 avoids direct contact between the patient's back and the sliding member 4, which may cause discomfort due to pressure on the back.

[0063] Please see Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13 as well as Figure 15 Vertical members 11 parallel to the adjusting arm 2 are fixedly provided on both sides of the sliding member 4. An mounting member 18 is fixedly provided between the vertical members 11 on both sides. A reciprocating member 20 parallel to the mounting member 18 is slidably provided between the vertical members 11 on both sides. A moving component is also provided between the mounting member 18 and the reciprocating member 20. The moving component is used to drive the reciprocating member 20 to move back and forth on the back of the vertical member 11 along the length direction of the vertical member 11.

[0064] The reciprocating member 20 is provided with a percussion component, which is connected to the vertical member 11 through a transmission component. When the reciprocating member 20 moves along the length direction of the vertical member 11 from one end near the side fixing member 1 to the direction away from the side fixing member 1, the percussion component percusses the patient's back on both sides.

[0065] The vertical members 11 on both sides are fixedly connected to the side fixing members 1 by a horizontal plate. An air supply assembly is installed on the horizontal plate. The air supply assembly is connected to the moving assembly. The air supply assembly is used to continuously supply air to the patient when the moving assembly moves back and forth along the length direction of the vertical member 11, so as to achieve the effect of assisted breathing.

[0066] In this invention, the moving component drives the reciprocating component 20 to move back and forth along the length of the vertical component 11 on the back of the patient. During the upward movement, the moving component drives the percussion component to percuss the lungs on both sides of the patient, helping sputum to be removed from the respiratory tract. In addition, the moving component also drives the air supply component to continuously supply air to the patient, assisting the patient in breathing when coughing.

[0067] In addition, the load-bearing component 3, the sliding component 4, and the connecting component 6 can make the adjusting arms 2 on both sides and the side fixing component 1 form a whole, which is not easy to fall apart and can adapt to beds of different widths.

[0068] As another embodiment of the present invention, please refer to Figure 3 and Figure 4 The clamping structure includes a sleeve 14 rotatably disposed below the side fixing member 1 on one side, a lead screw 13 rotatably fitted on the sleeve 14 on one side, and a screw tube 12 threadedly connected to the lead screw 13.

[0069] A sleeve 16 is fixedly provided below the side fixing member 1 on the other side, and a locking member 17 for cooperating with the sleeve 16 is fixedly provided on the screw tube 12. A rotating wheel 15 is fixedly provided at the end of the lead screw 13 away from the screw tube 12.

[0070] In this embodiment, when installing the device, first separate the locking member 17 and the sleeve 16, rotate the clamp 14 so that the screw 13 and the screw tube 12 are parallel to the side fixing member 1 on the same side, and insert them into the bed frame on both sides of the bed from above the bed. Then, press the side fixing members 1 on both sides along the length direction of the load-bearing member 3 so that the two are close to each other, and lock the side fixing members 1 on both sides onto the bed frame on both sides. Then rotate the clamp 14 so that the screw 13, the screw tube 12 and the locking member 17 on the screw tube 12 are rotated to correspond to the sleeve 16.

[0071] Rotate the wheel 15 to rotate the lead screw 13 while keeping the screw tube 12 from rotating with the lead screw 13. Adjust the position of the engaging member 17 so that one end is aligned with the insertion port of the sleeve 16. After adjusting one end of the engaging member 17 to be aligned with the insertion port of the sleeve 16, rotate the screw tube 12 and the lead screw 13 around the sleeve 14 to engage the engaging member 17 into the sleeve 16. After engaging the engaging member 17 into the sleeve 16, further rotate the wheel 15 to make minor adjustments to the screw tube 12. Move the screw tube 12 closer to the sleeve 14 to securely engage the side fixing members 1 on both sides of the bed frame.

[0072] As another embodiment of the present invention, please refer to Figure 2 and Figure 7 The vertical member 11 has a groove 28 along its length on its back side, and the reciprocating member 20 has a slider 27 fixedly provided on both sides facing the vertical member 11. The slider 27 is slidably engaged in the groove 28.

[0073] The moving assembly includes a motor 19 fixedly mounted on the mounting member 18, an output shaft passing through and rotatably engaging with the mounting member 18, and a rotating arm 21 with one end fixed to the end of the output shaft passing through the mounting member 18; the other end of the output shaft extends into the motor 19 and is connected to the rotor of the motor 19.

[0074] The other end of the rotating arm 21 is rotatably provided with a chuck 23 on the side facing the reciprocating member 20, and a groove plate 22 is fixedly provided along the length direction of the reciprocating member 20 on the side facing the rotating arm 21, which is engaged with the chuck 23.

[0075] In this embodiment, the motor 19 drives the output shaft to rotate, which in turn drives the rotating arm 21 to rotate. The rotating arm 21 drives the chuck 23 at one end to make a circular motion. The chuck 23 and the groove plate 22 work together to drive the reciprocating component 20 to move back and forth along the groove 28 under the guidance of the slider 27 and the groove 28.

[0076] As another embodiment of the present invention, please refer to Figures 7-16 The striking assembly includes a drive shaft 36 rotatably mounted on the side of the reciprocating member 20 facing the vertical member 11, a cam 37 fixed on the drive shaft 36, a fitting 39 fixed on the reciprocating member 20 by a tripod, a telescopic member 38 passing through the fitting 39, and a striking member 40 fixed on the end of the telescopic member 38 facing the vertical member 11.

[0077] The striking element 40 is made of a soft material and is in the shape of a bucket, with the opening of the bucket-shaped striking element 40 facing the vertical element 11.

[0078] In detail, the telescopic member 38 has a cylindrical part and a square part. The striking member 40 is fixedly disposed at the end of the cylindrical part away from the square part. A guide block is provided at the connection between the cylindrical part and the square part, which slides and engages with the inner wall of the fitting member 39. An elastic member 41 is sleeved on the cylindrical part. One end of the elastic member 41 abuts against the end of the fitting member 39 near the striking member 40, and the other end abuts against the guide block. A roller is rotatably disposed at the end of the square part near the drive shaft 36, which rolls and engages with the cam 37. The drive shaft 36 is connected to the transmission assembly.

[0079] In this embodiment, when the reciprocating member 20 moves along the length of the vertical member 11 from one end near the side fixing member 1 to the direction away from the side fixing member 1, it drives the transmission shaft 36 to rotate. The rotating transmission shaft 36 drives the roller and the square part and guide block on the telescopic member 38 to slide in the fitting member 39 by means of the cam 37. During the sliding process, the elastic member 41 is reciprocated and compressed. In addition, the elastic force of the elastic member 41 causes the cylindrical part to drive the percussion member 40 to continuously percuss the position of the patient's back corresponding to the lungs, helping the sputum in the respiratory tract to fall off.

[0080] As another embodiment of the present invention, please refer to Figures 7-16 The transmission assembly includes a drive shaft rotatably mounted on the side of the reciprocating member 20 facing the vertical member 11, a unidirectional rotating structure connecting the drive shaft and the vertical member 11, and a bevel gear set connecting the transmission shaft 36 and the drive shaft.

[0081] The drive shaft is parallel to the telescopic member 38, and the bevel gear set includes a first bevel gear 34 fixed on the drive shaft and a second bevel gear 35 fixed on the transmission shaft 36 near one end of the drive shaft and meshing with the first bevel gear 34.

[0082] To increase the transmission stability of the drive shaft, a bushing fixed to the reciprocating member 20 is rotatably fitted on a section of the drive shaft away from the first bevel gear 34.

[0083] In this embodiment, when the reciprocating member 20 drives the drive shaft to move from the end near the side fixing member 1 to the direction away from the side fixing member 1, the one-way rotation structure drives the drive shaft to rotate. However, when the reciprocating member 20 drives the drive shaft to move from the end away from the side fixing member 1 to the direction near the side fixing member 1, the one-way rotation structure does not drive the drive shaft to rotate.

[0084] When the drive shaft rotates, the first bevel gear 34 and the second bevel gear 35 drive the transmission shaft 36 to rotate. The transmission shaft 36 then drives the telescopic member 38 to move back and forth along the sleeve member 39 through the cooperation of the cam 37 and the elastic member 41, thereby driving the percussion member 40 to continuously percuss the corresponding lung lobes on the patient's back, realizing percussion of the patient's back from bottom to top to assist in expectoration.

[0085] As another embodiment of the present invention, please refer to Figures 11-14 The unidirectional rotation structure includes a unidirectional toothed plate 30 fixed on the side of the vertical member 11 facing the motor 19, a movable tooth 32 elastically swinging on the unidirectional toothed plate 30, and a gear 29 fixedly installed on the end of the drive shaft away from the reciprocating member 20 and cooperating with the movable tooth 32.

[0086] Furthermore, the one-way toothed plate 30 is provided with a plurality of toothed grooves at equal intervals, inclined toward the side fixing member 1. A rotating column 31 for rotatably installing the movable tooth 32 in the toothed groove, a fixing sleeve fixed on the inner wall of the toothed groove, and a spring piece 33 that is fixedly fitted with the fixing sleeve on one side and attached to the movable tooth 32 on the other side are fixed in the toothed groove.

[0087] In this embodiment, when the reciprocating member 20 drives the drive shaft and the gear 29 fixed at the end of the drive shaft to move from the end near the side fixing member 1 to the direction away from the side fixing member 1, since the movable tooth 32 cannot deflect away from the spring piece 33 under the constraint of the tooth groove, the gear 29 rotates under the action of the movable tooth 32, and finally drives the drive shaft to rotate.

[0088] When the reciprocating component 20 drives the drive shaft and gear 29 to move from the end away from the side fixing component 1 to the direction closer to the side fixing component 1, the gear 29 transmits force to the movable tooth 32. The movable tooth 32 can deflect around the rotating column 31 in the tooth groove by squeezing the spring 33, making room for the teeth on the outer periphery of the gear 29, causing the gear 29 not to rotate.

[0089] It should be noted that the resistance that the gear 29 needs to overcome to rotate includes the rotational friction between the drive shaft and the reciprocating member 20, the transmission friction between the bevel gear set, the rolling friction between the cam 37 and the roller, the elastic force of the elastic member 41, and the sliding friction between the guide block and the sleeve member 39; while the elastic force generated by the movable tooth 32 driving the spring plate 33 to produce elastic deformation is much smaller than the above-mentioned resistance, so the gear 29 will not rotate when it moves from the end away from the side fixing member 1 to the direction closer to the side fixing member 1.

[0090] As another embodiment of the present invention, please refer to Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 as well as Figure 15 The air supply assembly includes an air box 26 fixedly mounted on the horizontal plate, a track plate 24 fixedly mounted on the output shaft, a sealing element 42 slidably mounted in the air box 26, and a connecting rod 25 connecting the sealing element 42 and the track plate 24.

[0091] An opening is provided on the side of the air box 26 facing the track plate 24 through which the connecting rod 25 passes, and a guide sleeve is fixedly provided at the opening to slide and cooperate with the connecting rod 25. One end of the connecting rod 25 extends into the air box 26 and is fixedly connected to the sealing element 42, and the other end cooperates with the track plate 24.

[0092] The track plate 24 is in the shape of a straight groove. One end of the track plate 24 is fixedly connected to the output shaft. A groove with the same shape as its outer periphery is provided on one edge of the track plate 24.
