Description

Spoon for Parkinson patient

Technical Field

The open-chain is a spoon for Parkinson patients, belonging to the technical field of teaching aids.

Technical Field

Parkinson's disease is the most common degenerative disease of the central nervous system of the elderly, which is so named because it was first described by a british doctor named parkinson. In 2013, the total number of Parkinson patients is more than 5000 million, and the number of sick people is increased year by year along with irregular diet and movement of people. The hand tremor of the Parkinson's disease patient is usually static tremor, and the frequency is generally 4-6H_ZThe frequency of the vibration is jittered, and the frequency and the amplitude of the vibration are changed along with the development of the disease course. When a patient eats or drinks water, the normal progress of eating can be ensured only by keeping food static relative to the oral cavity, and if the food static relative to the oral cavity cannot be kept, the patient cannot eat normally, so that the life quality of the patient is seriously affected, and huge negative effects are caused to the daily life of the patient. In order to maintain the survival of the patients, special nursing is needed for eating food, the high nursing cost brings serious economic burden to the patients and families thereof, and no medical method for curing the Parkinson's disease is developed at present. Thus, by existingThe technical means meets the eating demand of the patient, inhibits and eliminates the influence of shaking hands of the patient on eating, improves the independent eating ability of the patient, and has important practical significance for the patient himself and the family thereof, even the whole society. Therefore, different researchers adopt different technical means to realize the anti-shaking of the food intake so as to meet the food intake requirement of the patient. Chinese patent publication No. CN104490211A discloses an anti-shake ladle, including ladle main part and the portion of holding, the portion of holding sets to the single-ended cavity form of opening day, the fixed many light elastic components that are provided with on the portion of holding inner wall, the upper end of ladle main part inserts the portion of holding inside from the open end, the ladle main part is arranged in the axis of the portion of holding, many light elastic components are fixed connection ladle main part tip respectively, the structure that many light springs are constituteed "hangs" the ladle main part and arranges the center of the portion inner chamber of holding in, utilize many light spring elastic deformation to reduce the shake of ladle main part. However, because the coefficient of stiffness of the spring is uniform and constant, the deformation of different parts of the spring is the same, and the deformation of the spring is still transmitted to the spoon main body, so that the influence on the elimination of the shaking of the spoon main body is limited. Chinese patent publication No. CN105380480A discloses an anti-shake spoon, which comprises a spoon main body and a holding part, wherein the top end of the holding part is flush with the gravity center of the spoon main body, the top end of the holding part is connected with the spoon main body through a rotating part, and a plurality of elastic members are arranged in the circumferential direction of the spoon main body. However, the problem that the coefficient of stiffness of the spring is uniform and constant is still not solved, and the problem that the gravity center of the spoon is greatly changed when the spoon is used for containing food is also ignored, so that the expected effect cannot be achieved in the practical application of the technology.

the handle sleeve is in a hollow cylindrical shape, is sleeved on the spoon handle in a penetrating manner, enables the spoon handle to be positioned on a central axis of the handle sleeve, and comprises an inner layer and an outer layer; the inner layer is made of rigid materials and plays a supporting role; the outer layer is made of flexible materials, so that the shaking of the handle sleeve can be damped, and the comfort level of holding the handle sleeve is improved;

the shaking preventer is used for preventing shaking of the sleeve from being transmitted to the spoon body, the shaking preventer is a coil spring group formed by coaxially connecting a plurality of same coil springs in parallel, the wire diameter of an elastic strip forming the coil spring is gradually increased from the outer end to the inner end, the density of the coil spring is gradually increased from the outside to the inside, and the coefficient of stiffness of the coil spring is increased from the outside to the inside; the inner end points of the coil springs are respectively fixed at the stable position of the spoon handle, the outer end points of the coil springs are respectively fixed on the inner wall of the handle sleeve, the inner end points of the coil springs are uniformly distributed on the spoon handle along the circumferential direction, and the outer end points of the coil springs are uniformly distributed on the inner wall of the handle sleeve along the circumferential direction, so that the stress of the spoon body is balanced; when a hand holding the handle sleeve shakes, the shaking of the handle sleeve firstly causes the peripheral shaking of the coil spring and gradually transmits the shaking to the center, the shaking coefficient of the coil spring is gradually increased from outside to inside, the shaking of the coil spring is gradually attenuated from outside to inside, the shaking at the center of the coil spring is hardly carried out, the shaking of the handle sleeve is counteracted by the shaking at the periphery of the coil spring, and the spoon body located at the center of the coil spring is hardly shaken.

Furthermore, the inner layer of the handle sleeve is made of metal or plastic, and the outer layer of the handle sleeve is made of rubber material.

Furthermore, the outer surface of the handle sleeve is provided with anti-skid grains.

Further, the shake damper is a coil spring group formed by coaxially connecting four same coil springs in parallel.

Further, the coefficient of stiffness of the coil spring is gradually increased from 0.1 to 3.0 from outside to inside.

The invention has the beneficial effects that: the invention provides a spoon for patients with Parkinson's disease, wherein a plurality of same coil springs are coaxially connected in parallel to form a shake resistance device, a spoon body is hung in a hollow handle sleeve through the shake resistance device, and the hanging position is the integral gravity center of the spoon head when the spoon head is filled with food. When the handle sleeve shakes, shaking of the handle sleeve firstly causes shaking of the periphery of the coil spring and gradually transfers the shaking to the center, and as the coefficient of stiffness of the coil spring is gradually increased from outside to inside, the shaking of the coil spring is gradually attenuated from outside to inside, the shaking is hardly generated at the center of the coil spring, and the shaking of the handle sleeve is counteracted by the shaking of the periphery of the coil spring, so that the spoon body at the center of the coil spring is hardly shaken, and the requirement of independent eating of a patient suffering from Parkinson's disease can be met.
