Description

Technical Field

[0001] The invention belongs to the technical field of rehabilitation equipment, and in particular relates to a postoperative recuperation and rehabilitation device suitable for critically ill patients. Background Art

[0002] Cerebral hemiplegia is a disease that causes dysfunction of the upper and lower limbs, facial muscles, and lower tongue muscles after brain damage. It is also a common symptom of acute cerebrovascular disease.

[0003] Due to cerebral hemiplegia, most patients in the recovery period need to follow the doctor's advice and perform relevant hand exercises to stimulate blood circulation in the arm joints, relieve joint stiffness, and avoid the appearance of bone spurs between joints, which will affect the rehabilitation exercise effect of cerebral hemiplegia patients during the recovery period.

[0004] As the main part for completing the functions of the upper limbs, the wrist joint plays a very important role in daily life, especially for patients in the rehabilitation period of cerebral hemiplegia. The wrist joint is an important connecting bridge between the arm and the finger joints. The existing wrist joint rehabilitation trainers only drive the wrist to perform reciprocating auxiliary movements in a single and prescribed trajectory by rotating parts. Although it is beneficial to the rehabilitation of the patient's wrist to a certain extent, it also limits the recovery of the wrist joint to a certain extent. That is, the single movement mode increases the fatigue of the wrist joint during training, which not only causes limitations in training, but may also cause secondary injuries to the wrist joint.

[0046] Preferably, the outer walls of the pressure rod and the sleeve rod are equipped with matching toothed pulleys, and the diameter of the toothed pulley is larger than the width of the vertical section of the connecting plate and smaller than the vertical distance between the vertical sections on both sides of the door-type plate; the distance between the functional frame and the arm-moving plate is ten centimeters, and the rubber pads extend five centimeters from both ends of the arm-moving plate and the functional frame, and limiting grooves are provided on the top surfaces of the opening plate and the heightening beam away from the side guard plate.

[0047] The method of exercising the wrist joint end is to use the above-mentioned postoperative rehabilitation device suitable for critically ill patients to assist in the exercise. The specific steps are as follows:

[0048] S1: First, the patient's arm is initially fixed and comfortably supported by the functional frame and the arm motion board, and then the arm is further fixed by the cooperation between the flat belt and the buckle plate. During this process, the patient's arm is heated by the electric heating sheet to facilitate blood circulation;

[0049] S2: Then, a small motor drives a crank swing mechanism composed of a crank, a connecting rod and a movable plate to drive the patient's arm to swing, and in this process, the meshing transmission between the incomplete bevel gear and the full bevel gear causes the patient's wrist to reciprocate differently from the arm;

[0050] S3: Finally, the telescopic connecting rod and the wrist force column provide the patient with antagonistic support for positive flexion and extension rehabilitation exercises. At the same time, the telescopic spring and the ceramic ball cooperate to provide the patient with antagonistic support for reverse flexion and extension rehabilitation exercises.

[0051] The present invention has the following beneficial effects:

[0052] 1. The present invention drives the pressure rod and the ring sleeve to rotate through the crank rocker structure composed of a crank, a connecting rod and a movable plate, so that the functional frame and the arm moving plate synchronously drive the arm to make a reciprocating swinging motion on the horizontal plane. At the same time, through the mutual movement between the full-tooth bevel gear and the incomplete-tooth bevel gear, the push rod is prompted to reciprocate between swings, so that the arm can swing horizontally and reciprocate at a corresponding angle at the same time, which is beneficial to improving the diversity of wrist joint exercises and completely solving the singleness of exercise in traditional training equipment.

[0053] 2. Under the action of the self-elastic force of the telescopic connecting rod, the present invention promotes the continuous maintenance of the acting force between the wrist force column and the wrist joint. By adding the wrist force column, the antagonism during wrist joint exercise is improved. At the same time, through the torsion spring arranged between the shaft moving rod and the vertical frame, favorable conditions are created for the antagonistic environment of the wrist force column. Meanwhile, due to the self-elasticity of the torsion spring, it is avoided that the wrist force column is too rigid when provided, which is not conducive to the rehabilitation exercise of the wrist joint and even causes unnecessary secondary damage to the wrist joint during the rehabilitation period.

[0054] 3. Through the transmission effect of the toothed belt wheels between the pressure rod and the sleeve rod, the present invention enables the arm moving plate to perform corresponding auxiliary antagonism and massage training with the ceramic ball while driving the rotation of the wrist joint, improving the effect of the patient's wrist joint exercise. At the same time, through the compressibility of the telescopic spring between the cross column and the gasket, it is further avoided that the ceramic ball causes too rigid extrusion and antagonism to the wrist joint during the movement process, resulting in the wrist joint being exercised in a way that is not easy to recover.

[0070] In order to make the purpose, technical solution and advantages of the present invention clearer, the following further details the present invention in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0071] It should be noted that the terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation mode.

[0072] The following describes the specific implementation of the present invention in detail with specific embodiments.

[0073] Refer to Figure 1 And Figure 6 It can be known that the postoperative recuperation and rehabilitation device suitable for critically ill patients includes a coated bottom plate 1. Above one end of the coated bottom plate 1, there is an adjustment unit 2. Above the adjustment unit 2, there is a positioning unit 3. Above the other end of the coated bottom plate 1, there is an auxiliary exercise unit 4. Above the auxiliary exercise unit 4, there is a counter unit 5;

[0074] Refer to Figure 1 It can be known that at the four corners of the coated bottom plate 1, there are edge protection seats 11 fixed and installed by bolts. In the middle position of the top surface of the coated bottom plate 1, there is a raised beam 12. At one end of the raised beam 12, there is a C-shaped angle plate 13. The bottom horizontal section of the C-shaped angle plate 13 is fixedly connected to a small motor 22. At the same time, the top horizontal section of the C-shaped angle plate 13 is fixedly connected to a storage rack 23. And the pressure rod 27 is rotatably and cooperatively installed through the top horizontal section of the C-shaped angle plate 13. At the end of the top horizontal section of the C-shaped angle plate 13 far from the auxiliary exercise unit 4, there is a side protection plate 14.

[0075] Through the rectangular distribution of the edge guard base 11, not only the stress uniformity of the coated bottom plate 1 is fully improved, but also it is beneficial to create a stable exercise environment for the wrist joint, and to a certain extent, reduce the probability of secondary damage to the wrist joint;

[0076] By raising the height of the beam 12 to increase the positions of the positioning unit 3 and the counteracting unit 5, the foundation of the compound human engineering between the positioning unit 3, the auxiliary exercise unit 4 and the counteracting unit 5 is laid. At the same time, through the cooperation between the C-shaped angle plate 13 and the side guard plate 14, the stability of the positioning unit 3 and the adjusting unit 2 above the coated bottom plate 1 is improved.

[0077] Refer to Figure 1 and Figure 2 It can be known that the adjusting unit 2 includes: a base 21, which is arranged at one end of the coated bottom plate 1; a small motor 22, which is fixedly installed on the base 21 by bolts; a storage rack 23, which is arranged above the small motor 22 by bolts; a crank 24, which is fixedly installed on the outer wall of the output shaft end of the small motor 22; a connecting rod 25, which is rotatably installed at one end of the crank 24 away from the small motor 22; a movable plate 26, which is rotatably installed at one end of the connecting rod 25 away from the crank 24; a pressing rod 27, which is fixedly installed at one end of the movable plate 26 away from the connecting rod 25; a collar 28, which is fixedly installed at the top end of the pressing rod 27; a guide post 29, which is rotatably installed at the middle position of the top surface of the storage rack 23;

[0078] Refer to Figure 1 and Figure 2 It can be known that a top rod 291 is rotatably installed through the collar 28. A full-tooth bevel gear 292 is installed on the outer wall of one end of the top rod 291 close to the side guard plate 14. An incomplete-tooth bevel gear 293 meshing with the full-tooth bevel gear 292 is installed on the outer wall of the top end of the guide post 29. An opening plate 294 is installed at one end of the top side of the storage rack 23 away from the side guard plate 14;

[0079] Refer to Figure 1 , Figure 2 and Figure 3It can be seen that the positioning unit 3 includes: a functional frame 31, which is fixedly installed on the top of the side guard plate 14; three buckle plates 32, which are evenly installed at one end of the top surface of the functional frame 31; side plates 33, which are evenly distributed at the other end of the top surface of the functional frame 31, and correspond to the position and number of the buckle plates 32; a flat belt 34, which is detachably installed at one end of each of the side plates 33 by bolts, and cooperates with the buckle plates 32; two linkage plates 35, which are symmetrically distributed. The balancing seat 36 is fixedly mounted on the outer wall of the ring sleeve 28 close to the functional frame 31 and is fixedly connected to the functional frame 31; the opening plates 37 are two in number and are symmetrically distributed on the outer wall of the end of the top rod 291 away from the side guard plate 14 and are fixedly connected to the top rod 291. The shape of the opening plates 37 is consistent with that of the linkage plate 35; the arm moving plate 38 is fixedly mounted on the top of the two opening plates 37;

[0080] Reference Figure 1 and Figure 5 It can be seen that the inner wall of the flat belt 34 is detachably installed with a sponge pad 311, and air holes 312 are evenly opened on the sponge pad 311. The outer wall of the flat belt 34 is fitted with an electric heater 313. The middle position of the top surface of the functional frame 31 and the arm-moving plate 38 are both designed with arc chamfers. At the same time, the arc chamfers of the functional frame 31 and the arm-moving plate 38 are detachably installed with rubber pads 314. The distance between the functional frame 31 and the arm-moving plate 38 is ten centimeters, and the rubber pads 314 extend out five centimeters from both ends of the arm-moving plate 38 and the functional frame 31. The top surface of the opening plate 37 and the pad beam 12 away from the side guard plate 14 is provided with a limiting groove 295.

[0081] When the patient begins exercising:

[0082] First, the patient places the arm on the functional frame 31, and the wrist joint is placed on the arm motion plate 38. Thereafter, the arm is stably fixed on the functional frame 31 by passing the flat belt 34 through the buckle plate 32 (fastening the flat belt 34 to the buckle plate 32 through the external buckle). At the same time, the sponge pad 311 absorbs the sweat exuded by the patient during long-term exercise (the adsorption of the sponge pad 311 is enhanced through the pores 312), which not only improves the patient's experience and enthusiasm, but also increases the service life of the flat belt 34. In addition, the sponge pad 311 is subjected to corresponding heat treatment through the real-time heating effect of the electric heating plate 313 (the electric heating plate 313 is outside the flat belt 34, that is, it is separated from the sponge pad 311 to prevent the electric heating plate 313 from burning when drying the sponge pad 311), and the sponge pad 311 is quickly dried to improve its operation continuity and service life.

[0083] Then, by adding the rubber pad 314, the arm is flexibly protected to improve the patient's use experience. At the same time, by designing the rubber pad 314 on the functional frame 31 and the arm motion plate 38 to extend out of both ends of the aforementioned two components, it is avoided that the rigid section between the functional frame 31 and the arm motion plate 38 causes pressure on the patient's skin during exercise, thereby causing discomfort;

[0084] Finally, the crank 24 is driven to rotate by the small motor 22, and then the crank rocker structure composed of the crank 24, the connecting rod 25 and the movable plate 26 drives the pressure rod 27 to rotate. In this process, the ring sleeve 28 drives the push rod 291 to rotate, and the functional frame 31 is under the action of the linkage plate 35 (the structural stability of the functional frame 31 in this product is enhanced by the balance plate), and synchronously follows the ring sleeve 28 to drive the patient's arm to swing in the horizontal direction, thereby adding a method different from the traditional wrist joint exercise. In addition, when the push rod 291 follows the swing of the ring sleeve 28, the mutual movement between the full-tooth bevel gear 292 and the incomplete-tooth bevel gear 293 causes the push rod 291 to reciprocate at a certain angle, and drives the arm moving plate 38 to reciprocate at a corresponding angle through the opening plate, thereby realizing that when the arm follows the horizontal swing of the functional frame 31, the wrist joint is synchronously made to perform another reciprocating rotation motion different from the traditional exercise method under the action of the arm moving plate 38.

[0085] Reference Figure 2 and Figure 6 It can be known that the auxiliary exercise unit 4 includes: an arc seat 41, which is slidably installed in each limit groove 295; a connecting plate 42, which is fixedly installed between the two arc seats 41 by bolts, and is slidably installed with the top surface of the heightening beam 12; a door plate 43, which is plugged and installed on the arc seat 41 at the position of the heightening beam 12; a sleeve rod 44, which is rotatably installed in the middle position of the horizontal section at the bottom end of the connecting plate, and is rotatably installed with the horizontal section of the door plate 43 in a through-type; a hollow cylinder 45, which is installed on the top of the sleeve rod 44; a gasket 46, which is fixedly installed in the middle position of the inner wall of the hollow cylinder 45; a cross column 47, which is slidably installed in the middle position of the gasket 46, and is slidably installed between the outer wall of the hollow cylinder 45; a telescopic spring 48, which is sleeved and installed on the outer wall of the cross column 47, and is at the top of the gasket 46; a ceramic ball 49, which is rotatably installed at the top of the cross column 47;

[0086] Reference Figure 2 and Figure 6 It can be seen that the outer walls of the pressure rod 27 and the sleeve rod 44 are both equipped with mutually matching toothed belt wheels 271, and the diameter of the toothed belt wheels 271 is larger than the width of the vertical section of the connecting plate 42 and smaller than the vertical distance between the vertical sections on both sides of the door plate 43.

[0087] When the adjustment unit 2 is operating:

[0088] The sleeve rod 44 drives the hollow cylinder 45 to rotate synchronously under the action of the pressure rod 27 (the sleeve rod 44 and the pressure rod 27 are mutually transmitted through the toothed belt wheel 271), and then the ceramic ball 49 synchronously rotates with the hollow cylinder 45 under the action of the cross rod, and the ceramic ball 49 is correspondingly contacted and squeezed with the wrist joint during the rotation process. At the same time, the self-compressibility of the telescopic spring 48 ensures the interaction force between the ceramic ball 49 and the wrist joint, and provides antagonistic exercise for the traditional wrist joint deficiency, which is conducive to improving the rehabilitation exercise effect of the wrist joint;

[0089] The engagement between the two arc seats 41 and the limiting groove 295 can not only ensure the operating stability of the auxiliary exercise unit 4, but also provide linkage between the auxiliary exercise unit 4 and the adjustment unit 2, so that the auxiliary exercise unit 4 can always perform corresponding antagonistic unit 5 on the exercise of the wrist joint.

[0090] Reference Figure 4 It can be seen that the antagonistic unit 5 includes: two vertical frames 51, which are symmetrically distributed in the middle of the top surface of the arm moving plate 38; an axial moving rod 52, which is rotatably installed between the top ends of the two vertical frames 51; two key plates 53, which are symmetrically fixed on the outer walls of both sides of the axial moving rod 52; a telescopic connecting rod 54, which is slidably installed on the end surface of each key plate 53 close to the middle position of the axial moving rod 52; a wrist force column 55, which is fixedly connected to the end of the telescopic connecting rod 54 away from the axial moving rod 52 through a mounting plate; and rubber protrusions 56, which are evenly distributed on the outer wall of the wrist force column 55 based on the acupuncture points.

[0091] Reference Figure 4 It can be known that the end surface of the arm-moving plate 38 away from the axial moving rod 52 is symmetrically installed with an ear seat 561, and the outer walls of the two ear seats 561 are jointly rotatably installed with a primary rotating plate 562, and the end surface of the primary rotating plate 562 away from the arm-moving plate 38 is rotatably installed with a secondary rotating plate 563 through the ear seat 561, and the ear seat 561 is slidably installed with the telescopic connecting rod 54, and the end surface of the secondary rotating plate 563 away from the primary rotating plate 562 is rotatably installed with a tertiary rotating plate 564 through the ear seat 561, and the top and bottom surfaces of the adjacent positions of the primary rotating plate 562, the secondary rotating plate 563 and the tertiary rotating plate 564 are evenly installed with protective pads 565, and torsion springs are installed between the axial moving rod 52 and the key plate 53, the ear seat 561 and the primary rotating plate 562, the primary rotating plate 562 and the secondary rotating plate 563, and the secondary rotating plate 563 and the tertiary rotating plate 564.

[0092] By rotating the primary rotating plate 562, the patient's wrist joint is controlled to perform reciprocating flipping exercises in the same manner as in the traditional exercise method, with the difference that: the wrist force column 55 located above the wrist joint performs corresponding antagonistic training on the wrist joint during the rotation process, and the elastic force of the telescopic connecting rod 54 itself creates a strong guarantee for the confrontation between the wrist force column 55 and the wrist joint, and at the same time, the torsion spring added between the axial movable rod 52 and the vertical plate further provides a freer confrontation space for the confrontation between the wrist force column 55 and the wrist joint, thereby avoiding the wrist force column 55 with limited freedom, which affects the antagonistic training effect of the wrist force column 55 on the wrist joint;

[0093] Through the interaction between the rubber protrusion 56 and the wrist joint, a more scientific massage aid is provided for the confrontation exercise between the wrist force column 55 and the wrist joint (the layout of the rubber protrusion 56 is in accordance with the layout of the acupuncture points in the wrist joint), thus creating a more favorable environment for the patient's wrist joint exercise;

[0094] By adding a torsion spring between the primary rotating plate 562, the secondary rotating plate 563 and the tertiary rotating plate 564, on the one hand, the area where the palm is placed can better fit the shape of the palm, thereby avoiding an overly rigid palm placement area when the wrist joint rotates, which may cause discomfort to the patient during exercise. At the same time, the rubber pad 565 can prevent the skin from being clamped in the active area between the primary rotating plate 562, the secondary rotating plate 563 and the tertiary rotating plate 564 during the palm flipping process, thereby improving the overall safety and comfort of the equipment.

[0095] The working principle of the postoperative recuperation and rehabilitation device for critically ill patients provided by the present invention is as follows: Step 1: First, the patient's arm is stably fixed on the rubber pad 314 in the functional frame 31 and the arm motion plate 38 through the cooperation between the flat belt 34 and the buckle plate 32;

[0096] Step 2: Then, the small motor 22 drives the crank 24 rocker mechanism composed of the crank 24, the connecting rod 25 and the movable plate 26 to control the pressure rod 27 to drive the ring sleeve 28 to swing, and then the interaction between the full-tooth bevel gear 292 and the incomplete-tooth bevel gear 293 causes the push rod 291 to swing and drive the arm movable plate 38 to reciprocate at a corresponding angle;

[0097] Step 3: Finally, through the transmission effect of the toothed pulley 271, the ceramic ball 49 performs corresponding massage and auxiliary confrontation on the wrist joint during the rotation process. At the same time, the telescopic connecting rod 54 ensures the confrontation between the wrist force column 55 and the wrist joint, providing a diversified wrist joint training method.
