Description

The invention relates to the field of medicine and medical equipment and can be used for mechanical treatment of the patient’s body, namely, “dry” hydromassage of the spine and paravertebral muscles and ligaments in the absence of direct contact of his body with working fluid (water).

Establishment of Prior Art

Known bath for the implementation of the procedures of "dry" immersion [1]. “Dry” immersion refers to relatively new methods of physical impact. A person in the process of ontogenesis for several months is in conditions of partial weightlessness. In the aquatic environment, several factors act simultaneously on a person. First of all, this is a decrease in the action of gravitational forces, causing a decrease in the deformation of cells, organs and tissues. As a result, the hydrostatic pressure of the blood decreases, the load is removed from the musculoskeletal system, which is manifested in a change in muscle tone, level of motor activity. Redistribution of body fluids and a change in afferent flows cause a change in heart rate and blood pressure.

Known bath for performing the procedure of "dry" immersion, used in the treatment of children with perinatal encephalopathy [2]. This device consists of a standard children's bath and a medical compression film of standard sizes. The bathtub is filled with water at 0.75-0.8 of its volume. Over the water spreads a compression film with an allowance for free immersion of the child.

The disadvantages of this device include:

- the lack of reliable retention of the waterproof coating on the surface of the water without the formation of cracks under the weight of the patient’s body, through which water can flow to the patient;

- lack of guaranteed patient retention in the required position on this film;

- the inability to maintain the required water temperature for the required time.

- the device is intended for patients only in childhood.

A device is also known for performing the dry immersion procedure [3]. For its use (being in water without contact with it), a large bath is used, the water temperature in which should be constant (not lower than 34-35 ° C) and cause the patient a sense of comfort. The patient is laid on a waterproof fabric covered with a sheet, and, sinking under the weight of his body, sags in the water. The method of "dry" immersion is one of the methods of simulating weightlessness, adopted in space, which was proposed for use in sports.

The disadvantages of this device should be attributed, as in the above analogue:

- the lack of reliable retention of the waterproof coating on the surface of the water without the formation of cracks under the weight of the patient’s body, through which water can flow to the patient;

- lack of guaranteed patient retention in the required position on this film;

- the difficulty of maintaining the required water temperature for the required time, etc.

Also known devices for performing the procedure of "dry" immersion [4, 5], containing a bath with a waterproofing elastic coating on which the patient is placed for 30-45 minutes The water temperature is 35-36.6 ° C. As an insulating coating, a PVC sheet of 1-3 mm thickness is used.

The therapeutic effect is achieved due to the pronounced sedative effect and the redistribution of blood and tissue fluid with a change in hemodynamic parameters.

Also known are devices for performing the “dry” immersion procedure [6-8], comprising a bathtub with a water-insulating elastic coating on which a patient is placed, an electric heating element with automatic maintenance of water temperature, and pipelines for supplying and circulating water.

Such devices are characterized by complexity of design and heavy loads on the attendant medical personnel.

Characterization and criticism of the prototype

NOTE. In fig. 3 prototypes (its hydraulic circuit) for ease of understanding is supplemented by the image of the bath with the corresponding channels. It is given on a separate sheet in the form of “Explanations for the Operation Manual”.

The closest invention to the proposed according to the greatest number of similar features, technical nature, circuit design and achieved by using the result is a non-contact whirlpool bath described in [9].

Such a bath, selected as a prototype, contains:

- a container for storing the working fluid, made in the form of a bathtub itself, hermetically sealed on top with a thin elastic waterproof membrane,

- metal frame on which the bath is installed,

In other words, according to the information available to the applicant, there are no analogues that are characterized by sets of features identical to all the features of the claimed device.

These signs are significant and interrelated with the formation of a stable set of essential features sufficient to obtain the desired medical and technical result.

The applicant has also verified the compliance of the specified set of essential features of the device with three conditions (criteria) of patentability.

Verification of compliance of the claimed device with the patentability condition "novelty"

The presence of these features ensures compliance with the totality of essential features of the patentability condition of "novelty." However, no devices were found in which the medical and technical result was achieved by a similar set of essential features.

According to the information available to the applicant, the set of essential features characterizing the essence of the claimed invention is unknown, which allows us to conclude that its patentability “novelty” condition is in accordance with the current legislation.

Verification of compliance of the claimed device with the condition of patentability "inventive step"

To verify compliance with the requirements of inventive step, the applicant conducted an additional search and analysis of solutions in order to identify signs that match the distinctive features of the selected prototype, the results of which showed that the claimed object does not explicitly follow from the prior art defined by the applicant.

In other words, a comparison of the claimed device not only with the prototype, but also with other technical solutions in this and related fields of medicine and medical equipment showed that the latter do not contain features similar to those distinguishing the claimed device from the prototype.

Therefore, the claimed object meets the condition of patentability "inventive step" under applicable law.

It should be noted that between the set of essential features (distinguishing features) of the present invention and the achieved medical and technical result, there is a causal relationship, since the distinctive features were not identified in any of the analogues, and the achieved result is obtained only when all are used together exclusions of known and distinguishing features.

Thus, these signs are significant and interrelated with the formation of a stable set of essential features sufficient to obtain the desired medical and technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

Purpose and functions of structural elements of the bath

Actually, bath 1 is intended for storage of circulating working fluid, as well as for placement of moving structural elements of a “dry” massage in it.

The waterproof membrane 2 is designed to accommodate the patient on it during the reception of hydromassage procedures and is a thin and durable film (waterproof fabric), which ensures the direct contact of the patient’s body with the working fluid and at the same time transferring massage actions of the working fluid jets to his back . At the same time, all the therapeutic effects inherent in hydrotherapy are preserved.

The metal frame 3, made in the form of a frame mounted on supports 4, is the main supporting and connecting structural element of the bath 1 and ensures its rigidity and stability during the procedure.

Supports 4 are adjustable in height and also self-adjustable in the direction of movement.

The hollow wooden casing 5, sheathed with artificial coating (leatherette), is designed to protect the components and assemblies of the bath 1 located in its aggregate compartment 10 from mechanical damage, as well as to enhance the aesthetic properties of the appearance of the bath 1.

Ventilation grilles 6 and 7, made at the ends of the casing 5, an electric fan 8 and a water radiator 9 installed in the aggregate compartment 10 opposite one of the ventilation grilles 7, form a forced cooling system for the working fluid in the bath 1.

The aggregate compartment 10 is the space between the bottom of the bath 1 and the bottom of the frame 3, which houses the hydraulic system of the bath 1, as well as its other elements and assemblies.

The control software block 11 is designed to implement the program of procedures recorded therein by processing the information received at its inputs and issuing control signals to individual nodes and units of the device.

The remote control 12 serves to set and display the current values of the operating parameters of the bath 1 and consists of a corresponding keyboard and indicators in the form of a set of LEDs.

An audio signaling device 13 is built into the remote control 12 and provides sound information to the health worker and patient about the operation of the bath 1.

The electric heater 14 of the working fluid and the sensor 15 of its temperature together with the control unit 11 form a system for controlling the temperature of the working fluid in the bath 1. In this case, the temperature sensor 15 provides the formation of signals proportional to the temperature of the working fluid, and the heater 14 together with the block 11 - its heating to set temperature.

The circulation pump 16 provides circulation and cooling of the working fluid in the hydraulic system of the bath 1.

The hydromassage pump 17 together with the nozzles 27 and 28 are intended for the formation of massage jets of the working fluid in the bath 1.

The water filter 20 is designed to clean the working fluid flowing through the hydromassage pump 17 to the nozzles 27 and 28.

The carriage 26 is designed to accommodate nozzles 27 and 28 on it.

Thanks to the electric drive 29, the longitudinal movement of the carriage 26 along the bath 1 is achieved.

Thanks to the electric drive 31, the nozzles 27 and 28 can be rotated along circular paths with rotation planes parallel to the plane of the membrane 2.

The first 33, second 34 and third 35 Hall sensors in this device are displacement sensors. The first 33 and second 34 Hall sensors are designed to record the beginning and end of the trajectory of the longitudinal translational movement of the carriage 26. The third Hall sensor 35 provides a count of the number of revolutions of the nozzle 28.

Structurally, each of these sensors 33-35 consists of two "parts": "semiconductor" and "magnetic", based on a permanent magnet. Under the influence of the magnetic field of the second part, the Hall emf is induced in the first part of the sensor and enters block 11. Moreover, the semiconductors 33-1 and 34-1 are attached to the outer surface of the wall of the bath 1, and their common magnet 33-2 is rigidly connected to the carriage 26.

Through the drain valve 24 is the filling or discharge of the working fluid from the bath 1.

Circulating 16 and hydromassage 17 pumps, radiator 9, water filter 20, drain valve 24, pressure head 18, cooling 21 and drainage 23 channels form the hydraulic system of the bath 1.

Flexible kinematic connections 30 and 32 are structurally made on the basis of a gear belt.

The air-release valve 36 is designed to regulate (release) the air from under the membrane 2, to eliminate, if necessary, arising air “bubbles” underneath.

The device as a whole is intended for water massage of a patient without immersing him in water and thereby providing an effective therapeutic massage effect on the vertebral column and paravertebral muscles and ligaments of the patient by a non-contact (“dry”) method.

The lack of direct exposure to the aquatic environment on the patient dramatically reduces the number of contraindications to the use of this treatment method and the risk of infectious diseases.

Description of the bath (in dynamics)

Before starting work, bath 1 must be installed on a flat horizontal surface and the nozzles for supplying and discharging the working fluid must be connected to it.

The patient is placed on the membrane 2 of the bath 1 back down. Moreover, his head should be located in the head of the bath 1 (where there is no valve 36), and the axis of his spine should coincide with the longitudinal axis of symmetry of the bath 1.

With the inclusion of power automatically turns on the heater 14 of the working fluid. The heating time of the hydraulic fluid from room temperature (18 ° C) to 25 ° C is several tens of minutes and depends mainly on the ambient temperature.

Depending on the patient’s disease and condition, the attending physician determines the regimen and methodology of the therapeutic effect on his spine and paravertebral muscles and ligaments using this bath 1.

Therapeutic procedures in bath 1 are performed in 3 stages:

- input (task) of the procedure parameters;

- direct execution of the procedure;

- post-procedural rest.

When performing the procedures, for example, the following procedure parameters can be set:

- "water temperature";

- “duration of the procedure”;

- “hydromassage program”;

- other parameters.

The values of the parameters of the bath 1 can be entered (changed) using the remote control 12 both before starting the procedure, and in the process of its execution.

The type of the trajectory of movement of the massage jets is set programmatically and is implemented in the form of control signals coming from block 11 to the electric drives 29 and 31.

Note. Electric drives 29 and 31 are based on DC motors. When changing the polarity of the feeding voltage of their rotation.

The specific trajectory of the massage is determined by the ratio of the speeds of rotation of the nozzles 27 and 28, as well as the direction of their rotation. In this case, the electric drive 29 is “responsible” for the most part for the formation of longitudinal sections of the massage path, and the electric drive 31 for the formation of transverse sections of the path.

If only electric drive 30 is turned on, the straight paths shown in FIG. 7 a.

If both electric drives 30 are turned on and the directions of rotation change at the same time, some formed massage paths are shown in FIG. 7, b, c and d.

If a longer hydromassage of individual local portions of the patient’s back is required, the paths shown in FIG. 7, d.

The completion of the hydromassage procedure is accompanied by the sound signals of the detector 13.

The discharge of the working fluid from the hydraulic system of the bath 1 is carried out via pressure head 18, cooling 21 and drainage 23 channels through a drain valve 24.

Post-treatment activities

Post-treatment measures are carried out under the guidance of the attending physician and may include water and air procedures, herbal medicine, etc., which end with post-treatment rest.

findings

Thus, the proposed combination of essential features of the device allows you to expand the therapeutic capabilities of the device by making the nozzles movable in it.

The device as a whole is intended for water massage of a patient without immersing him in a working fluid.
