Description

Technical Field

[0001] The present invention belongs to the technical field of rehabilitation training, and in particular relates to a rehabilitation training device for cardiovascular medicine nursing. Background Art

[0002] Cardiology is a clinical department set up in hospitals to diagnose and treat cardiovascular diseases. The diseases treated include cardiovascular diseases such as angina pectoris, hypertension, arrhythmia, myocarditis and acute myocardial infarction. Cardiology surgery will cause patients to lose their ability to live for a period of time. In order to avoid muscle stiffness in patients after surgery, postoperative rehabilitation care is usually required for patients. The most commonly used rehabilitation care method for cardiology surgery is exercise therapy, which uses external force to cause the patient's muscles to contract and simulate the muscle state during exercise.

[0003] The Chinese invention patent with patent number CN113995630B discloses a rehabilitation training device for cardiovascular medicine nursing. The hydraulic push rod pushes the support seat to cooperate with the support plate to drive the upper limb support to rotate, rise or fall, which can assist patients in completing upper limb lifting rehabilitation training; the neck positioning pillow with a positioning groove and the head positioning pillow with a circular bracket can position the patient's neck and head; the transmission rod and belt drive can drive the rotating drum to roll and squeeze the patient's neck, avoiding insufficient blood supply to the brain caused by cervical vertebra compression of nerves due to long-term lying of the patient; through the transmission of the turntable, drive rack and bevel gear, the eccentric wheel can cooperate with the protrusion on the upper surface of the bracket block to achieve kneading and massage of the patient's cerebellum, which can improve the insufficient blood supply and hypoxia of the brain caused by long-term lying, and improve the rehabilitation training effect.

[0004] The device has the following problems: 1. Post-cardiology surgery patients experience stiffness in their joints due to prolonged lack of exercise. During rehabilitation training using exercise therapy, the process of extending and flexing the patient's upper limbs can easily cause significant compression forces on the shoulder and elbow joints, leading to joint damage. Furthermore, during upper limb lifting rehabilitation training, the patient's torso is pulled and moved, potentially causing tears in the surgical wound on the patient's chest.

[0005] 2. The device only provides rehabilitation training for the upper limbs and head and neck, which limits the number of areas covered and results in poor rehabilitation results. Furthermore, it cannot address back stiffness and itching that can occur when patients lie in bed for long periods of time.

[0006] 3. The device is connected to each other through various transmission components for rehabilitation training. The equipment transmission is too complicated, not flexible enough, and prone to errors, which causes great damage to the patient and affects the rehabilitation treatment effect. Summary of the Invention

[0007] The embodiment of the present application provides a low-injury rehabilitation training device for cardiovascular medicine nursing, which solves the technical problem that the rehabilitation training device in the prior art only performs rehabilitation training on the upper limbs and head and neck, resulting in poor rehabilitation effect, and the upper limb training causes high damage to the patient's body.

[0031] Furthermore, there are two elastic rope plates on both sides below the sac, one end of which is fixed to the patient's waist side at the bottom of the sac, and the other end is fixed to the patient's head side at the bottom of the sac. After being squeezed by the roller, the elastic rope plates can fix the sac at the squeezed position to prevent the sac from rebounding. When the roller returns, the elastic rope plates that are not squeezed by the roller return to their original elasticity.

[0032] Furthermore, the liquid inside the liquid capsule is pure water.

[0033] Furthermore, a heating component is provided inside the liquid capsule for heating the liquid in the liquid capsule.

The present application embeds the liquid sac 20 on the bed body 10, and squeezes the liquid inside the liquid sac 20 from the waist side to the head side through the moving mechanism 30, pushing the head side of the liquid sac 20 to rise, thereby performing rehabilitation training on the patient's upper body. At the same time, the flow of liquid in the liquid sac 20 drives the neck mechanism 40 and the head mechanism 50 to massage the patient's neck and head. This solves the technical problem in the prior art that the rehabilitation training device only performs rehabilitation training on the upper limbs and head and neck, resulting in poor rehabilitation effect, and at the same time, the upper limb training causes greater damage to the patient's body. The present application achieves the technical effect of performing low-injury and better-effect rehabilitation training on the patient's upper body through the ups and downs of the liquid sac.

[0063] Example 1

[0064] like Figures 1 to 3 As shown, the present application discloses a low-injury rehabilitation training device for cardiovascular medicine nursing, which includes a bed 10, a liquid bag 20, a moving mechanism 30, a neck mechanism 40 and a head mechanism 50;

[0065] The bed body 10 is a common frame-structured hospital bed. The liquid bladder 20 is a rectangular elastic air bladder filled with liquid and embedded in the bed body 10. The maximum contraction height of the liquid bladder 20 is greater than half of its original height. The liquid bladder 20 is greater than 80 cm in length and is used to support the upper body of the patient.

[0066] The liquid capsule 20 includes a capsule body 21 and a lower capsule body 22;

[0067] The capsule 21 is an elastic capsule that contracts when subjected to external force and rebounds to its original shape when no force is applied, and is used to carry the liquid inside the liquid capsule 20;

[0068] The lower sac 22 is a rectangular telescopic sac, the top of which is fixedly connected to the bottom of the head side of the sac 21, and the bottom is fixedly connected to the bed 10. It pushes up after the liquid enters and retracts downward after the liquid flows out, and is used to lift the sac 21 when the liquid enters itself;

[0069] Preferably, the liquid inside the liquid capsule 20 is pure water;

[0070] Preferably, a heating component is provided inside the liquid capsule 20 for heating the liquid in the liquid capsule 20 to improve the patient's lying comfort;

[0071] like Figure 4 As shown, the moving mechanism 30 is a track and lifting mechanism mirror-imaged on both sides of the bottom of the liquid capsule 20, including a guide rail 31, a support plate 32, a telescopic rod 33 and a roller 34, which is used to move the liquid in the liquid capsule 20 in the liquid capsule 20;

[0072] The guide rails 31 are linear rails mirror-imaged and arranged below the two sides of the liquid capsule 20. The bottom is fixedly connected to the bed 10. The length of the guide rails 31 is less than that of the liquid capsule 20 and is used to provide a moving path for the moving mechanism 30.

[0073] The support plate 32 is a rectangular plate, with wheels rollingly connected to the two sides of the bottom parallel to the guide rail 31, and the wheels rollingly connected to the rail 31. The top middle is fixedly connected to the telescopic rod 33 for carrying and driving the telescopic rod 33 to move;

[0074] The telescopic rod 33 is an electric telescopic rod, and a roller 34 is connected to the top in a rolling manner. The maximum lifting height can drive the roller 34 to the middle of the longitudinal height of the liquid capsule 20, and the minimum retracted height can drive the roller 34 to contact the bottom of the liquid capsule 20 without force, so as to drive the roller 34 to squeeze the liquid capsule 20.

[0075] The roller 34 is a cylindrical roller, the top of which contacts the bottom of the liquid capsule 20. The roller 34 is in rolling connection with the bottom of the liquid capsule 20, and its two sides are fixedly connected to the top of the telescopic rod 33, for squeezing the liquid inside the liquid capsule 20.

[0076] like Figure 5 As shown, the neck mechanism 40 is a neck soothing mechanism fixed above the liquid bag 20, including a neck positioning pillow 41, a neck rotating wheel 42, a short plate 43 and a long plate 44, which is used to position the patient's neck and massage the patient's neck by relying on the flow of liquid;

[0077] The neck positioning pillow 41 is a rectangular support with a low center and high sides, located above the sac 20 on the patient's neck, and is used to position and support the patient's neck;

[0078] The neck rotating wheels 42 are circular wheels, two in number, and are respectively provided on both sides of the inside of the neck positioning pillow 41. The outside of the neck rotating wheels 42 are fixedly connected to short plates 43 and long plates 44 arranged in sequence, and are used to drive the short plates 43 and long plates 44 to rotate when the liquid flows;

[0079] The short plate 43 is a soft rectangular plate. When the neck rotating wheel 42 rotates, the top of the short plate 43 can touch the patient's neck.

[0080] The long plate 44 is a soft rectangular plate. When the neck wheel 42 rotates, the top of the long plate 44 can squeeze and massage the patient's neck.

[0081] like Figure 6 As shown, the head mechanism 50 is a head soothing mechanism fixed above the liquid bag 20, including a head positioning pillow 51, a bump 52, a top rod 53 and a head rotating wheel 54, which is used to position the patient's head and massage the patient's head by relying on the flow of liquid;

[0082] The head positioning pillow 51 is a circular support with a hollow interior, located above the sac 20 at the patient's head, and is used to position and support the patient's neck;

[0083] The protrusions 52 are rubber protrusions evenly arranged inside the head positioning pillow 51. When the bottom is subjected to external force, they are pushed upwards to massage the patient's head under the action of external force.

[0084] The push rod 53 is an arc-shaped rod with a cylindrical protrusion on the top. The top of the rod contacts the protrusion 52 and can push the protrusion 52 to massage the patient's head.

[0085] The head wheel 54 is a rotating wheel radially arranged below the head positioning pillow 51, which rotates under the flow of liquid. The top middle part is fixedly connected to the push rod 53, and when it rotates, it drives the push rod 53 to push the protrusion 52, which is used to drive the push rod 53 to move under the flow of liquid.

[0086] Preferably, there are two elastic rope plates on both sides below the sac 20, one end of which is fixed to the patient's waist side at the bottom of the sac 20, and the other end is fixed to the patient's head side at the bottom of the sac 20. After being squeezed by the roller 34, the elastic rope plates can fix the sac 20 at the squeezed position to prevent the sac body 21 from rebounding. When the roller 34 returns, the elastic rope plates that are not squeezed by the roller 34 return to their original elasticity to prevent the liquid in the sac 20 from flowing back.

[0087] The working process of the low-injury rehabilitation training device for cardiovascular medicine nursing in the embodiment of the present application is as follows:

[0088] S1: The moving mechanism 30 is provided on the waist side below the liquid sac 20. The telescopic rod 33 is extended, driving the roller 34 to push upward, squeezing the liquid in the liquid sac 20 toward the head side. At the same time, the guide rail 31 drives the telescopic rod 33 and the roller 34 to move toward the head side of the liquid sac 20. The elastic rope plate fixes the liquid sac 20 to prevent the liquid in the liquid sac 20 from flowing back. The squeezed liquid in the liquid sac 20 gradually enters the lower sac body 22 below the head side of the liquid sac 20. The lower sac body 22 rises upward, which can drive the head side of the liquid sac 20 to rise, so that the patient's upper body slowly rises, achieving the effect of rehabilitation training for the patient's upper body;

[0089] At the same time, the liquid in the liquid bag 20 squeezed by the roller 34 enters both sides of the patient's neck, driving the neck rotating wheel 42 to rotate. The short plates 43 and long plates 44 arranged on the neck rotating wheel 42 rotate slowly, which can gently massage the patient's neck and promote blood circulation in the patient's neck.

[0090] At the same time, the liquid discharged by the neck rotating wheel 42 enters the bottom of the head positioning pillow 51, which can drive the head rotating wheel 54 to rotate, and drive the top rod 53 above the head rotating wheel 54 to lift the bump 52 on the head positioning pillow 51. The bump 52 can massage the patient's head and accelerate the blood circulation in the brain.

[0091] S2: When the roller 34 returns from the head side of the liquid sac 20 to the waist side, the liquid in the liquid sac 20 gradually returns to its original position. The returned liquid can drive the head rotating wheel 54 to reverse, so that the patient's head continues to be massaged. At the same time, the returned liquid causes the neck rotating wheel 42 to reverse, driving the short plates 43 and long plates 44 arranged on the neck rotating wheel 42 to massage the patient's neck in the opposite direction;

[0092] S3: Repeat the above steps, gradually increase the lifting height of the telescopic rod 33 during the rehabilitation process, so that the lifting amplitude of the head side of the liquid bag 20 is continuously increased, which can gradually improve the slow rise and fall of the patient's upper body, promote the patient's blood circulation, and improve the rehabilitation treatment effect.

[0093] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0094] The present invention solves the technical problem that the rehabilitation training device in the prior art only performs rehabilitation training on the upper limbs and head and neck, resulting in poor rehabilitation effect, and at the same time, the upper limb training causes high damage to the patient's body. The present invention achieves the technical effect of performing low-damage and better-effect rehabilitation training on the patient's upper body through the fluctuation of the liquid sac.

[0095] Example 2

[0096] The following problems were found during the test of the above embodiment: 1. Patients need to lie in bed for a long time after surgery. Because the material of the liquid sac 20 is relatively soft, the patient may experience slight discomfort in the waist and back;

[0097] 2. Although there is an elastic rope plate under the sac 20 to prevent the liquid inside the sac 20 from flowing back, when the sac 20 is squeezed by the moving mechanism 30, the liquid inside may still flow back slightly. Although this will not affect the normal operation of the rehabilitation training device, it will affect the lifting height of the sac 20 and reduce the therapeutic effect of the rehabilitation training device.

[0098] 3. When the roller 34 is used to squeeze the capsule 21, the roller 34 will be lifted to a greater height in the later stages of rehabilitation training, causing more liquid to be pushed up, resulting in greater resistance during movement, thus affecting the stability and safety of the device.

[0099] like Figures 7 and 8 As shown, this embodiment improves the liquid bag 20 on the basis of the above embodiment, and adds a rubber ball 23, a blocking net 24, a floating gate 25 and an air bag 26;

[0100] The rubber balls 23 are air-sac balls distributed inside the liquid sac 20 and arranged in sequence within the longitudinal barrier net 62. They float above the liquid in the liquid sac 20 to support the human body and prevent the patient from experiencing slight discomfort in the waist and back after lying down for a long time.

[0101] The blocking net 24 is a flexible net located in the middle of the liquid sac 20 in the longitudinal direction. The rubber ball 23 is separated above the blocking net 24. The roller 34 is raised to the bottom of the blocking net 24 at most to wrap the rubber ball 23 and prevent the movement of the rubber ball 23 inside the liquid sac 20 from affecting the movement of the roller 34.

[0102] like Figures 9 and 10 As shown, the floating gate 25 is a telescopic mechanism composed of multiple proportional levers, with the top fixedly connected to the top of the bladder body 21 and the bottom fixedly connected to the airbag 26, dividing the barrier net 24 into multiple sections. When the roller 34 passes by, the floating gate 25 is driven by the liquid flow and the elastic rope plate to rise and close, which is used to further prevent the liquid inside the liquid bladder 20 from flowing back.

[0103] The airbag 26 is a rectangular elastic airbag with its bottom fixedly connected to the bottom of the bag body 21. When the roller 34 passes by, it drives the floating gate 25 to rise, so as to reduce the resistance encountered when the roller 34 moves.

[0104] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0105] 1. By adding a rubber ball 23 and a barrier net 24 inside the bladder 20, the carrying capacity of the bladder 20 is improved, preventing the patient from experiencing slight discomfort in the waist and back after lying down for a long time;

[0106] 2. By adding a float gate 25 inside the liquid sac 20 and utilizing the characteristics of the float gate 25 closing after the roller 34 passes and opening after returning, the liquid inside the liquid sac 20 is prevented from flowing back, thereby avoiding affecting the lifting height of the liquid sac 20 and improving the therapeutic effect of the rehabilitation training device;

[0107] 3. By fixing the airbag 26 under the floating gate 25, the resistance encountered by the roller 34 when traveling is reduced, and the stability and safety of the equipment are increased.

[0108] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
