IN-BED EXERCISING AND MONITORING DEVICE FIELD OF THE INVENTION

[0001] The present invention relates generally to beds. More particularly, the present invention relates to an electromechanically operable in-bed exercising device for exercising the body of incapable patients whilst monitoring health status thereof.

BACKGROUND OF THE INVENTION

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Patients, obese people and old age people usually tend to develop various health problems like obesity, joint pain, paralysis, cardiac disorders, blood pressure and muscular pains. Often, medical practitioners take care of the aforementioned health problems using medicinal treatments and recommending long-duration bed rests.

[0004] For instance, paralysis can occur in a localized form, most of which is caused by trauma, seizure, and accidents that cause damage to the nervous system (mainly linked with Spinal cord injuries which constitute the Central Nervous System). Paralysis can be treated with the allopathic method and the medical science came up with various amounts of mobility aids to make a patient feel less biased, mentally as well as physically, by inducing activeness.

[0005] Usually, such long bed rests stiffen the body of the patient and worsen their health conditions. Unfortunately, while being well-known to the fact that yoga is not only a source of energy generation but has also proven to be a healing source for some of the problems that allopathy has taken years to treat patients and old age people, they inhibit themselves from exercising their body because of their physical incapability, mental pressure and health issues.

[0006] Exercising, especially yoga has not only provided aid to many patients but also to the people who want to imbibe good value in their lifestyle. Yoga is said to be beneficial for all age groups, it comes with tons of good habits and making the body stretched up. Yoga is always seen to be an aid for old age, cardiac as well as paralytic patients.

[0007] Exercising helps improve muscle strength, aerobic fitness, balance, flexibility and mobility which are important for older people. Herein, Yoga is a low-impact activity that is easy on the joints, which is imperative in any exercise regime for seniors hence. It can be performed with less fatigue and has a long term effect on the patient.

[0008] Several attempts have been made by the researchers to ensure automatically facilitated exercising to the body of incapable patients by designing examining cum exercising beds. Many mechanisms for the bed have been patented which just aim at assisting patients after a surgery or for those who can't sit on their own. These beds are configured to assist in performing any sort of exercise. Instead, these beds can just be used for lifting patients on their back or lifting their foot.

[0009] Some attempts have been made to improve spinal arrangement or prevent spine-related defects like lumbar, thoracic, thoracolumbar, and many more defects. Some other works include electromechanical exercise machines used by normal users. However, researchers have still not been able to automatically induce complicated positions therewith and hence more flexible in-bed exercising devices are needed.

[0010] Additionally, there are strong possibilities that health conditions (such as blood pressure, heart rate, pulse rate, oxygen rate and so on) of exercising patients may worsen while performing such exercises. No mechanism has yet been included in examination cum exercising beds to provide remotely controlled real time monitoring of a patient's health status.

[0011] Hence, there exists a strong need for real-time monitoring of the health status of the patient while facilitating user-controlled and automatically generated exercising positions in the patient's body, thereby ensuring the smooth functioning of a patient's body.

OBJECTS OF THE INVENTION

[0012] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0013] An object of the present invention is to provide a multipurpose bed for supporting various needs of a patient as well as practitioners.

[0009] The present invention relates to a bed distinguished by an additional feature of robotically exercising a patient's body into different postures and monitoring multiple health parameters alongside.

[0010] Referring to Figure la, the disclosed embodiments include a mainframe 3, a backrest section 1 and a leg-rest section 2 affixed on the mainframe 3, a headrest member 4 and a pair of shoulder rest members 5 arranged on the backrest. The mainframe 3. The mainframe 3 is preferably made up of hollow pipes of stainless steel material but not limited thereto. The pipes can be arranged in a cuboidal manner to make the structure of the mainframe 3. From each of the bottom corners of the mainframe 3, heavy-duty casters may protrude out to add robustness and agility to the mainframe 3. The mainframe 3 is structured to act as a main structural building block for all mechanisms, accessories and applications undertaken by the present disclosure.

[0011] Referring to both Figure la and Figure 6, a backrest section 1 and a leg rest section 2 are used to prepare a base for a patient, ideally in a lying position. Both the aforesaid sections 1, 2 are abutted together using a hinge joint. The backrest section 1 further comprises of a headrest member 4 that can be positioned centrally down the top edge of the backrest section 1, a pair of shoulder-rest members 5 that can be positioned diagonally below the headrest member. All sections 1, 2 and members 4, 5 can be made up of but not constrained to stainless steel, wood, metal and plastic. The headrest member 4 and the shoulder-rest member 5 can rest the head and shoulders of the patient as and when required. Additionally, the backrest section 1 includes a pair of belt slots 7, herein elliptical, such that a patient may clench thereof as and when required.

[0012] Referring to Figure 3, the leg-rest section 2 can bear the lower body of the patient and comprises of multiple belt slots 7 equidistantly arranged on its surface to tie the patient's legs using a rope and thereby prevent any misbalancing due to reasons including but not limited to exercising, irritation, patient's motion, attacks, etc. The belt slots 7 are designed to have cushioned mountings.

[0013] Moreover, some user-specific mountings can be adapted for performing different yoga positions which include hand muscles to stimulate the different sections of body parts, wherein such mountings can be provided as accessories depending on the user's needs. Collectively, the back-rest safety belt slots and lower section support belt slots 7 can not only hold hands and legs but will also be used to hold the whole body using a cushioned belt 7 with adjustable straps, thus forming a safe yoga bed.

[0014] According to an embodiment, atleast two support frames 6 are fenced around substantial portions of the backrest section 1 and elongated portions of leg rest section 2. Herein, the support frames 6 contain a multitude of semicircular protrusions, each containing atleast one slot 7 that may be clenched by the patient to retrain unbalancing of his/her body.

[0015] Figure lb illustrates a view similar to the preceding one, but for showcasing a limpid view, wherein the outer cover and guards are removed for depicting the mechanism behind the disclosure. The backrest section 1 is made functional using a linear actuator 9a located at the bottom portion of the upper half of the mainframe 3 and the leg-rest section 2 is made functional using another linear actuator 9b located at the bottom portion of the lower half of the mainframe 3.

[0016] Atleast two actuators 9a, 9b are connected to the atleast two linkages 8a, 8b respectively, such that for backrest section 1 there is backrest linkage 8a (first linkage) connected to transmit the motion of the backrest actuator 9a (first actuator) onto the backrest linkage 8a, further helping in the conversion of translator motion of the backrest linkage 8a into the rotary movement of the backrest section 1 connected thereto. Similarly, the leg-rest section 2 can be made functional using the leg-rest linkage 8b (second linkage) which will transfer motion from the leg-rest linear actuator 9b (second actuator), thereby helping in the conversion of translator motion of the leg-rest linkage 8b into the rotary movement of the leg-rest section 2 connected thereto.

[0017] Preferably, linear actuators 9a, 9b can be fixed to the mainframe 3 using a linear actuator mount 14 and both the aforementioned sections 1, 2 are connected to their respective linkages 8a, 8b using revolute joints 15 chosen from but not limited to pin joint, hinge joint and ball bearing rollers, wherein such joints not only make connectivity but also add freedom of movement in a revolving sense. Pin joint is a revolute joint adapted for the present disclosure and has 1 Degree of Freedom (DOF) to rotate the connected sections 1, 2. All the movements generated in the backrest section 1 and the leg-rest section 2 due to the aforementioned actuators 9a, 9b and linkages 8a, 8b assist in robotically exercising the body of the patient in different angular positions like performing inverted exercises, tilted exercises, Trendelenburg position (also known as Cardiopulmonary Resuscitation position) based exercises, etc.

[0018] Figure 2a and 2b illustrate a front view of the present disclosure having backrest section 1 in the upright position and the leg-rest section 2 in the horizontal position. One or more longitudinal supporters 10a and latitudinal supporters 10b are connected to both the linkages 8a, 8b for supplementing rotatory motion of the backrest section 1 and the leg-rest section 2. The supporters 10a, 10b are connected to the linkages 8a, 8b using revolute joints, therefore enabling strongly supported movement of sections 1, 2. These supports can be inserted in the hollow sections cut in the linkages 8a, 8b or can be held using the ball bearing roller support applied for the purpose of stress dissipation.

[0019] According to an embodiment of present disclosure, multiple sensors can be arranged at substantial portions of the proposed device to capture multiple parameters relating to the body like blood pressure, angle of sections, heart rate, oxygen level, seat belt status, etc. The Saturation oxygen (SpO2) sensor can be used to keep track of the Oxygen level of the patient's blood, and blood pressure (BP) sensors can be used to measure the blood pressure before and after the yoga sessions and/or any exercise session. Pulse Rate (PR) sensors can keep track of the number of times the user's heartbeats in one minute. Tilt sensors are small, feasible, and powerful in nature and can be affixed to detect the orientation of the sections. They can be equipped to detect the tilt, with the help of a ball bearing inserted in a protractor-like holder to determine the angle of inclination. Seat belt sensors can also be suitably arranged to alarm for untied arms and legs while during exercises.

[0020] In an embodiment, a computing unit 11 can be equipped at a suitable position with a display to act as a human-machine interface. The computing unit 11 may consist of multiple components like micro-controllers (for receiving the data which will be gathered from the sensors), distribution-box, power pack for battery back-up, timer, cycle button, ON/OFF button, settings button, etc. operable via a remote controller 12. The computing unit 11 can also have a button to determine the movement of the backrest section 1 and the leg-rest section 2. The timer button can be used to set the timing of the session or the therapy and the cycle can be applied to determine the no. of the frequency of that exercise with some preferred interval of time so that patient or a user does not feel fatigued.

[0021] Firstly, the inclination and orientation as per the exercise to be performed can be decided by the user/patient to set up the exercise/yoga the patient is intended to perform. Thereafter, the duration of the exercise can be set using the timer button and the frequency of the exercise is set using the cycle button. The display can be used to showcase the user-selected values and the values received from the sensors to ensure live monitoring of health parameters, thereby monitoring the health status of the patient and instructing/alarming any necessary action to keep up with the patients' health and/or interests. It would be appreciated by a person skilled in the art that these values can also be used for research purposes or improvement of the device.

[0022] Figure 4a, 4b and 4c depict the side, perspective and front view respectively of the ac backrest section 1 and the leg-rest section 2 are capable of moving in one degree of freedom using the backrest actuator 9a and leg-rest actuator 9b respectively, the maximum angle that can be traveled by the backrest section 1 range from 90 degrees downwards to 90 degrees upwards whereas that for leg-rest section 2 ranges from 50 upwards to 90 degrees upwards. Herein, the angles are mentioned with respect to the horizontal axis.

[0023] As indicated in Figure 5a and 5b, the side and perspective view of the maximum angle of rotation possible between the two leg-rest section 2 and backrest section 1 is shown. The maximum reachability of the backrest section 1 can be 90 degrees downwards whereas that of leg-rest section 2 can be 90 degrees upwards, maxing a maximally achievable total gap of 180 degrees. Figures 4a, 4b, 4c, 5a and 5b predict the viability and feasibility of the invention.

[0024] Figure 7 is a block diagram demonstrating the connectivity of different components, according to a preferred embodiment. The heart of the present disclosure lies in the control unit that connects with other components to conduct the workflow of the invention. The inputs provided to the control unit of the proposed device include but are not constrained to the power supply, battery, medical equipment for mapping blood pressure, pulse rate and oxygen saturation level, and the multiple sensors used therewith. The output components of the control unit of the proposed device are chosen to be but not restricted to the afore discussed arrangements of actuators 9a, 9b and linkages 8a, 8b. Additionally, the aforesaid computing unit 11 acts as both input and output components for the control unit such that the control unit retrieves the parameter values provided by the sensors/equipments and settings delivered by the user/patient to display the results and move sections 1, 2 accordingly.

[0025] It would be appreciated by a person skilled in the art that although the present invention has been described in terms of a hospital bed having exercising and monitoring means for the patient, other modifications of the invention are possible. Apart from hospitals, the proposed exercising bed may be used at homes as well. Client-specific designs can be designed to imbibe more comfortable and robust support, various modifications may be possible to suit the needs of people of different monetary levels.

[0026] A person skilled in the art would also admire that a voice feedback system can be incorporated in the aforementioned disclosure to provide voice notifications to the patient regarding section's angles, health status, seat belt status, etc. Moreover, additional emergency as well as safety features may be incorporated to impart the reliability and trust of patients in the invention. The invention can also be set up in gyms and/or private facilities for promoting the health and fitness of obese/paralytic/old age people and/or patients.

[0027] People skilled in the art would also appreciate that research and development can help in making this invention more user friendly and intelligent. Modifications may be done to ensure automatic leveling of the actuators 9a, b as per the body type, weight, height, etc. of the patient. Additionally, the aforementioned disclosure can also be used for sleeping purposes. More specifically, actuators 9a, 9b can be configured to align the posture of a sleeping patient, thus enabling correct sleeping patterns and postures of the patient.

[0028] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context.
