RU48765U1 - POSTURE SELF-CORRECTION INDICATOR - Google Patents

Abstract

The invention relates to medical equipment and is an indicator of posture self-correction, which is fixed on the sternum using elastic tapes with rivet buttons at the ends that do not constrain the patient's movements. If the patient deviates in any direction by an angle of more than 9 °, the indicator informs him that his posture does not correspond to the correct one with the help of speech in the form of the phrases “sit straight, not stoop”, etc. Speech stops as soon as the patient so that the patient can’t get used to the sound monotony - the electronic unit provides a two-level warning method - first using speech of relatively low intensity, and after 15 seconds with a speech of higher intensity. 8-10 seconds. The technical result is an improvement in the consumer properties of the indicator, achieved firstly by using a more advanced tilt sensor and, secondly, by a two-level alert patient with a speech: first of relatively low intensity, and then after 15 seconds A higher intensity speech Improving the consumer properties of the tilt sensor is achieved through the use of a pendulum and an optoelectronic pair with an open input in it,

located in a hollow sphere, allowing to construct a sensor, the operability of which is not impeded by poor lighting. In order to exclude the influence of external light on the state of the optoelectronic pair, the hollow sphere is made of a material opaque to light. In the immediate vicinity of the optoelectronic pair, inside the sphere, a pendulum is suspended on a thin thread, the lower end of which serves as a reflector. When the pendulum deviates from an imaginary line passing through the pendulum suspension point and the optoelectronic pair diode, the phototransistor pulse disappears. The absence of this impulse is a signal for triggering the electronic unit of the indicator of self-correction of posture. To damp the oscillations of the pendulum, the sphere is filled with a damper liquid. The sensor is configured by the patient without assistance very quickly and is carried out using a liquid level, which is mounted outside in the center of the upper part of the sphere and acts as a kind of handle for orienting the sphere, which is pivotally mounted in the indicator housing. Setting the indicator comes down to turning the sphere in the body so that the level air bubble is aligned with its middle. Fastening belts having length adjustments are made of elastic tapes, at the ends of which rivet buttons are attached, which serve as indicator fixtures on the patient’s sternum, can be easily removed for washing.

Description

The invention relates to medical equipment and is a prophylactic and therapeutic agent in preserving, regulating and developing proper posture in various and common diseases of the musculoskeletal system, especially among children.

It can be used by patients during the rehabilitation period on the spine and after back injuries and is a means of preventing the development of myopia.

Patents of such devices are known, based on either the principle of sound signaling [1, 2] or the principle of notifying the patient about incorrect posture using electrical signals [3]. However, they all have certain disadvantages that do not allow to make a device with high consumer properties.

The closest prototype is a posture control device described in the utility model certificate [4].

The name ″ posture control device ’should be replaced by another, more appropriate name" posture self-correction indicator ’, since the last name most fully reflects the physical nature of the device, which assumes the patient’s active role in posture correction.

In [4], a tilt sensor was described that monitors the patient's deviation in any direction, which allowed the author to propose the most constructive device. However, this sensor has the following disadvantages: a) the sensor does not work in poor lighting, b) has a long decay time, c) when the patient is adjusted to the correct posture, the sensor has different angular sensitivity, d) the sensor is relatively large.

Since the patient gets used to the same sound level, in work [4] a combined warning of incorrect posture is applied using sound and electrical signals. As a result, the electrical circuit of the device turned out to be more complex and expensive and, therefore, less reliable. In addition, the presence of a bracelet worn on the patient’s wrist also creates certain difficulties in the operation of the device, and the fastening straps are difficult to release for washing.

The objective of the invention is to develop an indicator of self-correction of posture, which should not have these shortcomings and have improved consumer properties. The problem is solved firstly - through the development of a more advanced tilt sensor, in which not external lighting of the visible range is used as a radiation source, but autonomous, internal; not a ball, but a pendulum is used as a detector of incorrect posture, and also because the receiver is not a separate phototransistor, but a phototransistor, which is part of

optoelectronic pair. Secondly, the goal is also achieved due to the fact that the space in which the pendulum is filled with damper fluid., And through the use of a liquid level.

Since the main consumer of this invention will be children, given the gaming approach, a talking indicator will be preferable to an indicator that simply emits intermittent sound signals.

And therefore, in the third - the task is also solved due to the fact that the patient is notified of incorrect posture by a speech in the form of phrases: "sit upright" or "do not stoop", which are recorded in the electronic unit. So that the patient to the maximum extent can’t get used to the monotony of voice notification, it is carried out first with a speech of relatively low intensity, and after 15 seconds, if he does not accept the correct posture, then with a speech of higher intensity. Voice notification stops immediately as soon as the patient accepts the correct posture, but begins only after 8-10 seconds. after deviation by an angle of more than 9 ° to either side of the position corresponding to the correct posture. Correct posture is accepted by the patient in a natural way.

The self-correction indicator of posture (see Fig. 1) consists of a housing 1, a power supply 2, a sound speaker 3, an electronic unit 4, elastic belts 5 with rivet buttons 6 for attaching the indicator and tilt sensor 7. In the case when the self-correction indicator posture is applied in

public places, that is, where the sound should not attract outsiders, in the indicator housing 1, a switch socket 8 is provided, where a plug with a cable is inserted, blocking the speaker located in the indicator housing and connecting a headphone.

The tilt sensor (see Fig. 2) is a small hollow sphere 9 made of opaque material, inside of which there is an optoelectronic pair 10 with an open entrance at the bottom, and a pendulum 12 suspended from above on a thin thread 11, the lower end of which is a reflector, which is located in close proximity to an optoelectronic pair. When the pendulum deviates from an imaginary line passing through the pendulum suspension point and the optoelectronic pair diode, the phototransistor pulse disappears. The absence of this impulse is a signal for triggering the electronic unit of the indicator of self-correction of posture.

Since the optoelectronic pair 10 is located inside the opaque sphere 9 and has its own independent radiation source, the state of the phototransistor of the optoelectronic pair depends only on the position of the lower end of the pendulum and does not depend on external lighting. To reduce the decay time of the oscillations of the pendulum 12, the sphere 9 is filled with a damper liquid.

The sensor is adjusted using a miniature liquid level 13, which is mounted externally in the center of the upper part of the sphere and which is a handle for turning the sphere. The sphere 9 is pivotally mounted in the housing 14 and can be easily fixed in any

position in a solid angle of 0-30 °, which allows the patient to independently and very quickly configure the sensor. The tilt sensor works as follows (it is assumed that it is mounted in the self-correction indicator of posture, and that power is supplied to the optoelectronic pair): after the patient has put on the self-correction indicator of posture and accepted the correct posture, he needs to bind the tilt sensor to the orientation direction of the patient’s body , which was realized by the patient as a result of taking correct posture. To do this, it is enough to turn and fix the sphere 9 of the sensor in the housing 14 so that the air bubble is in the center of the liquid level 13. In this case, the lower end of the pendulum 12 will be oriented against the diode of the optoelectronic pair 10. Since the diode of the optoelectronic pair is a source of autonomous radiation, then the latter, reflected from the lower end of the pendulum 12, enters the phototransistor of the optoelectronic pair 10, which launches the electronic unit of the device. If the patient deviates in any direction from the position corresponding to the correct posture, the sensor pendulum 12 will deviate and the diode radiation will not get into the phototransistor of the optoelectronic pair 10. In this case, the indicator electronic unit will sound an alert in the form of the phrases “Sit straight” or “ not stooped "that the patient has incorrect posture, which will remind him of this until the patient accepts the correct posture.

Thus, the sensor:

1) controls any direction of patient deviation in excess of 9 °,

2) works in any light condition,

3) has the same sensitivity in angle,

4) quickly configurable

5) has smaller dimensions.

Those. The claimed inclination sensor has improved operational characteristics, which distinguishes it from the nearest prototype. The sensor can be manufactured in the factory, where there is the necessary machine park.

Fastening belts made of elastic tapes have mating buttons at the ends that allow you to remove the washing belts.

Thus, due to the use of the described tilt sensor, and due to the fact that the electronic unit has two modes of exposure to the patient’s hearing organs - weaker and stronger, and also because of the fastening straps, which are now easily removable for washing, as they are equipped with buttons- rivets - the proposed indicator of self-correction of posture has better operational and consumer properties compared to other counterparts.
