Description

A posture adjustment device for patients with pulmonary edema Technical Field

[0001] This invention relates to the field of medical technology, specifically to a body position adjustment device for patients with pulmonary edema. Background Technology

[0002] Pulmonary edema is an increase in lung water content caused by a disorder in the function of fluid exchange between blood vessels and tissues in the lungs.

[0003] This disease can severely impair respiratory function and is a common cause of acute respiratory failure in clinical practice. The main clinical manifestations include extreme dyspnea, orthopnea, cyanosis, profuse sweating, paroxysmal cough with copious white or pink frothy sputum, symmetrical moist rales throughout both lungs, and butterfly-shaped patchy opacities on chest X-ray. In the late stages, shock and even death may occur. Early arterial blood gas analysis may reveal low O2, low CO2 partial pressure, severe hypoxia, CO2 retention, and mixed acidosis.

[0004] When patients are resting, they should be in a comfortable position, generally sitting or sitting upright with their legs dangling, to reduce the amount of venous blood returning to the heart, which can reduce the burden on the heart.

[0005] However, traditional chairs often cannot adjust the backrest angle according to the patient's needs, which greatly reduces the patient's comfort when resting. Some chairs can adjust the backrest angle, but they cannot allow for a small range of movement after adjustment, so they are still not comfortable enough.

[0006] Therefore, we propose a body position adjustment device for patients with pulmonary edema to solve the above problems. Summary of the Invention

[0031] 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.

[0032] Example 1:

[0033] Please refer to Figures 1-2. The present invention provides a technical solution: a body position adjustment device for patients with pulmonary edema includes a housing 1 and a seat 2 fixed on the housing 1. A backrest 3 is rotatably connected to one side of the seat 2. An angle adjustment component 4 is provided inside the housing 1 for adjusting the backrest 3 and providing a certain amount of space for the backrest 3 to move.

[0034] The angle adjustment assembly 4 includes a drive shaft 41 that is telescopically inserted into the top surface of the outer casing 1, and the drive shaft 41 and the outer casing 1 are rotatably connected. A gear 42 is sleeved on the drive shaft 41. A gear 43 that meshes with the gear 42 is rotatably connected inside the outer casing 1, and a worm gear 44 that is coaxially fixed with the gear 43. Two symmetrically distributed mounting plates 45 are fixedly connected to the inner side wall of the outer casing 1. A horizontal shaft 46 is rotatably connected between the two mounting plates 45. A worm wheel 47 that meshes with the worm gear 44 is sleeved on the horizontal shaft 46.

[0035] In the initial state, gear 1 42 and gear 2 43 are meshed with each other. Rotating the drive shaft 41 can drive gear 1 42, which is sleeved on its surface, to rotate. Gear 1 42 can drive gear 2 43, which is meshed with it, to rotate. Gear 2 43 can drive worm 44, which is fixed coaxially with it, to rotate. Worm 44 can drive worm wheel 47, which is meshed with it, to rotate.

[0036] Two symmetrically distributed mounting plates 48 are fixedly connected to the inner wall of the outer shell 1 and located directly below the two mounting plates 45. A rocker arm 49 is rotatably connected to each of the two mounting plates 48. A push rod 410 is fixed to the free end of the two rocker arms 49. The push rod 410 abuts against the rear surface of the backrest 3. Two elastic bands 411 are wound around the surface of the horizontal shaft 46. The free end of the elastic band 411 is fixed to the push rod 410.

[0037] When the horizontal axis 46 rotates in the direction of arrow A, it can wind up the two elastic bands 411, thereby driving the push rod 410 to move upward. The push rod 410 can push the backrest 3, making the angle between the backrest 3 and the seat 2 smaller.

[0038] However, when the patient leans back forcefully, they can press down on the backrest 3, which has a certain range of motion.

[0039] Example 2:

[0040] Please refer to Figures 3-6. This embodiment further illustrates Example 1. A neck pillow 5 is provided on the backrest 3, and an adjustment component 6 is provided inside the outer shell 1 to adjust the position of the neck pillow 5 according to the patient's needs.

[0041] In use, since the patient is in a sitting position, if an external backrest is used, the backrest will fall off every time the patient gets up, and the backrest must be picked up again every time the patient sits down.

[0042] If the pillow is fixed directly to the backrest 3, it cannot be adapted to the height of all patients;

[0043] By setting the position adjustment component 6, the position of the neck pillow 5 can be adjusted according to the patient's needs without affecting the adjustment of the backrest 3.

[0044] The position adjustment component 6 includes a U-shaped frame 61 fixed on the inner wall of the outer shell 1. A threaded rod 62 rotatably connected to the U-shaped frame 61 passes through it. An internal threaded sleeve 63 threadedly connected to the surface of the threaded rod 62 is fitted on it. A limiting rod 64 passing through the internal threaded sleeve 63 is vertically fixed on the bottom surface of the inner wall of the outer shell 1. The internal threaded sleeve 63 slides up and down along the limiting rod 64.

[0045] The threaded rod 62 is a hollow structure, and an internal gear ring 65 is integrally fixed on the inner wall of the threaded rod 62. The drive shaft 41 passes through the threaded rod 62, and a gear 66 that meshes with the internal gear ring 65 is sleeved on the surface of the drive shaft 41.

[0046] In the initial state, gear 1 42 and gear 2 43 are meshed with each other, and gear 3 66 is located below threaded rod 1 62. When it is necessary to adjust the position of the neck pillow 5, pull the drive shaft 41 upward. The drive shaft 41 can drive gear 1 42 and gear 3 66 sleeved on its surface to move upward, so that gear 1 42 disengages from gear 2 43 and gear 3 66 enters the threaded rod 1 62 and meshes with the internal gear ring 1 65.

[0047] Rotate the drive shaft 41 again, and the drive shaft 41 can drive the gear 3 66 sleeved on its surface to rotate. The gear 3 66 can drive the internal gear ring 1 65 that meshes with it to rotate. The internal gear ring 1 65 can drive the threaded rod 1 62 to rotate. The threaded rod 1 62 can drive the internal threaded sleeve 63 to move downward.

[0048] The position adjustment assembly 6 also includes a rod 67 vertically fixed to the surface of the internal threaded sleeve 63. One end of the rod 67 is telescopically inserted with a rod 68. The free end of the rod 68 is fixedly connected to a U-shaped seat 69. A spring 610 is fixedly connected between the U-shaped seat 69 and the internal threaded sleeve 63. The spring 610 is sleeved on the surfaces of the rod 67 and the rod 68. A sliding rod 611 passing through the backrest 3 is vertically fixed to the surface of the neck pillow 5. A strip groove 612 for sliding the sliding rod 611 is opened on the surface of the backrest 3. The free end of the sliding rod 611 is rotatably connected to the U-shaped seat 69.

[0049] In use, the internal threaded sleeve 63 can drive the rod 67 fixed on its surface to move downwards, the rod 67 can drive the rod 68 telescopically inserted at one end to move downwards, the rod 68 can drive the U-shaped seat 69 fixed at one end to move downwards, and the U-shaped seat 69 can drive the neck pillow 5 to move downwards through the slide rod 611.

[0050] If you need to drive the neck pillow 5 to move upward, simply rotate the drive shaft 41 in the opposite direction.

[0051] Example 3:

[0052] Please refer to Figures 6-8. This embodiment further illustrates Example 2. A foot pedal 7 is provided on the outer side of the outer shell 1, and a lifting assembly 8 for adjusting the foot pedal 7 is provided inside the outer shell 1.

[0053] When resting, patients usually sit or sit upright with their legs dangling to reduce the amount of venous blood returning to the heart, which can reduce the burden on the heart.

[0054] However, due to the different heights of each patient, some patients cannot put their feet on the ground after sitting down, which greatly reduces the comfort of the device.

[0055] During use, patients can place both feet on the footrests 7. The height of the footrests 7 can be adjusted according to the height of different patients by setting the lifting component 8, which increases the patient's comfort and improves the applicability of the device.

[0056] In use, the position adjustment of the neck pillow 5, the angle adjustment of the backrest 3, and the position adjustment of the footrest 7 are all accomplished through the same drive shaft, which greatly improves the convenience of the device.

[0057] The lifting assembly 8 includes a crossbar 81 fixed to one side of the foot pedal 7 and located inside the housing 1. A threaded rod 82 is rotatably connected inside the housing 1, passing through the crossbar 81 and threadedly connected to the crossbar 81. The crossbar 81 is penetrated by a limiting rod 64 and slides along the limiting rod 64. A vertical groove 84 is provided on the surface of the housing 1 for the crossbar 81 to move up and down.

[0058] The threaded rod 82 is hollow, and an internal gear ring 83 is integrally fixed inside the cavity. The internal gear ring 83 is compatible with the gear 66.

[0059] In use, when it is necessary to adjust the position of the pedal 7, push the drive shaft 41 downward. The drive shaft 41 can drive the gear 3 66 sleeved on its surface to move downward, so that the gear 3 66 enters the threaded rod 2 82 and meshes with the internal gear ring 2 83.

[0060] Rotate the drive shaft 41 again. The drive shaft 41 can drive the gear 3 66 sleeved on its surface to rotate. The gear 3 66 can drive the threaded rod 2 82 to rotate through the internal gear ring 2 83. The threaded rod 2 82 can drive the crossbar 81 threaded to it to move upward. The crossbar 81 can drive the foot pedal 7 fixed at one end to move upward to the preset position.

[0061] If it is necessary to drive the pedal 7 to move downwards, simply rotate the drive shaft 41 in the opposite direction.

[0062] Working principle:

[0063] In the initial state, gear 1 42 and gear 2 43 are meshed with each other. Rotating the drive shaft 41 can drive gear 1 42, which is sleeved on its surface, to rotate. Gear 1 42 can drive gear 2 43, which meshes with it, to rotate. Gear 2 43 can drive worm 44, which is fixed coaxially with it, to rotate. Worm 44 can drive worm wheel 47, which meshes with it, to rotate.

[0064] When the horizontal axis 46 rotates in the direction of arrow A, it can wind up the two elastic bands 411, thereby driving the push rod 410 to move upward. The push rod 410 can push the backrest 3, making the angle between the backrest 3 and the seat 2 smaller.

[0065] However, when the patient leans back forcefully, he can press the backrest 3, which has a certain range of motion.

[0066] In the initial state, gear 1 42 and gear 2 43 are meshed with each other, and gear 3 66 is located below threaded rod 1 62. When it is necessary to adjust the position of the neck pillow 5, pull the drive shaft 41 upward. The drive shaft 41 can drive gear 1 42 and gear 3 66 sleeved on its surface to move upward, so that gear 1 42 disengages from gear 2 43 and gear 3 66 enters the threaded rod 1 62 and meshes with the internal gear ring 1 65.

[0067] Rotate the drive shaft 41 again. The drive shaft 41 can drive the gear 3 66 sleeved on its surface to rotate. The gear 3 66 can drive the internal gear ring 1 65 meshing with it to rotate. The internal gear ring 1 65 can drive the threaded rod 1 62 to rotate. The threaded rod 1 62 can drive the internal threaded sleeve 63 to move downward.

[0068] The internal threaded sleeve 63 can drive the rod 67 fixed on its surface to move downwards. The rod 67 can drive the rod 68 telescopically inserted at one end to move downwards. The rod 68 can drive the U-shaped seat 69 fixed at one end to move downwards. The U-shaped seat 69 can drive the neck pillow 5 to move downwards through the slide rod 611.

[0069] If you need to drive the neck pillow 5 to move upward, simply rotate the drive shaft 41 in the opposite direction.

[0070] The patient can place both feet on the foot pedal 7. When the position of the foot pedal 7 needs to be adjusted, the drive shaft 41 is pushed down. The drive shaft 41 can drive the gear 3 66 sleeved on its surface to move down, so that the gear 3 66 enters the threaded rod 2 82 and meshes with the internal gear ring 2 83.

[0071] Rotate the drive shaft 41 again. The drive shaft 41 can drive the gear 3 66 sleeved on its surface to rotate. The gear 3 66 can drive the threaded rod 2 82 to rotate through the internal gear ring 2 83. The threaded rod 2 82 can drive the crossbar 81 threaded to it to move upward. The crossbar 81 can drive the foot pedal 7 fixed at one end to move upward to the preset position.

[0072] If it is necessary to drive the pedal 7 to move downwards, simply rotate the drive shaft 41 in the opposite direction.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
