Description

The invention relates to the field of medical technology, namely, in proctology to fragmentation, that is, to crushing, fecal plug in the distal part of the human rectum, and household sanitary equipment and can be used to fragment the fecal plug in the distal part of the human rectum when his bowel movements.

There are known methods of fragmentation of a fecal plug in the rectum, when a doctor/nurse manually crushes a fecal plug directly in the rectum and removes fragments of the plug from it, or a person independently performs fragmentation by pressing fingers in the perineum.

There is a known method of fragmentation of the fecal plug in the rectum of a person during his defecation, in which a person crushes the fecal plug in the distal part of the rectum by pressing his fingers on the body in the region of the gap between the coccyx and anus [Source: "Constipation" https://zdorovie7i.ru /blog/zapory-avtor-stati-vrach-gastroenterolog-doktor-medicinskih-nauk-professor-muhutdinova-farida-ibragimovna.html].

The main disadvantage of such fragmentation of the fecal plug is the need for a person to perform manual manipulations on the body near the anus. Before this, it is necessary to apply an antibacterial protective cream to the hands or put on rubber gloves or fingertips and remove them from the hands immediately after the procedure. This carries increased risks in the sanitary and hygienic safety of a person when carrying out such a toilet. In addition, a person experiences physical inconvenience when performing such manual manipulations during defecation, and they are not always acceptable and welcomed by him, based on his ethical, hygienic considerations and physical capabilities. Technical means for the independent implementation of fragmentation of the fecal plug in the rectum by a person have not been found.

The objective of the invention is to create a technical means for the fragmentation of a fecal plug in the rectum by a person independently by pressing on the rectum through the soft tissues of the body in the region of the gap between the coccyx and the anus. This will make it possible to fragment the fecal plug in the distal part of the human rectum without performing manual manipulations on the body near the anus, which will also increase the sanitary and hygienic safety of a person when he goes to the toilet.

This problem is solved due to the fact that the proposed device for fragmenting a fecal plug in the distal part of the human rectum by pressing on the skin of the body in the area of the gap between the coccyx and anus, consists of an element fixed relative to the pelvis of the human body, an associated movable element that touches the body between the coccyx and the anus with the possibility of pressing on the body, and the drive of movements associated with the movable element with the possibility of imparting movements to it.

Elements fixed relative to the pelvis of the human body can be an object, a structure that supports the pelvis of the human body, or is held motionless relative to the pelvis of the body, for example, associated with it, or located nearby, motionless relative to the pelvis of the human body, for example, being in the "eagle pose". A movable element is connected to the element fixed relative to the pelvis of the body, touching the skin of the body between the coccyx and the anus with the possibility of pressing on it. The movable element, coupled with the drive of reciprocating movements, presses on the body between the coccyx and the anus, which leads to crushing of the fecal plug in the distal part of the rectum. Thus, the use of the proposed device causes fragmentation of the fecal plug in the human rectum and makes it unnecessary to perform manual manipulations on the body near the anus, which also increases the sanitary and hygienic safety of a person during such procedures.

In the proposed device, the element, which is fixed relative to the pelvis of the human body, is made in the form of a seat associated with the toilet bowl with a hole in it.

The movable element is made as a slider in the form of a movable section of a tubular retractable two-section telescopic boom, the other section of which, as a guide of the slider, is connected with the seat by its supporting end. The axis of the boom is located in the median longitudinal vertical plane of the seat and is orthogonal to the skin of the body in the middle of the gap on it between the anus and the nearest orthogonal projection of the apex of the coccyx onto the skin of the body. For comfortable contact with the body, a pommel is placed on the free end of the slider, or it is made in the form of a segment of an oval of rotation, conjugated with the end face with its base and with its smooth surface, smoothly passing to the surface of the slider tip.

The supporting end of the boom with the slider is connected to the seat by a stop in the form of a console, consisting of a single or a chain of sequentially arranged tubular rigid links, the ends of which are hinged with the possibility of fixation are paired with each other. In this case, the first or only stop link from the seat is made in the form of a retractable two-section telescopic boom, the sections in which are connected with each other with the possibility of fixation. The end of the outer section of the boom is associated with a seat on its end in the rear part of its hole. The last, or only, link of the stop with its free end is hinged with the possibility of fixation with the supporting end of the boom with the slider. The stop axis is located in the median vertical plane of the seat.

The movement drive consists of a muscular, that is, a reciprocating movement engine that converts the energy of the muscles into another type of energy, and a transmission of movements that transfers these movements to the slider. The transmission of movements consists of a flexible cable movable in an elastic and conjugated with the supporting part of the movement engine braid. The cable is connected at one end to the element of the movement engine that generates these movements, and at the other end to the slider. The supporting part of the engine is a fixed, basic unit, a part in it, relative to which movements are generated.

The muscular motor of movements is made in the form of a tubular retractable two-section telescopic boom, the end of the supporting section of which is associated with a seat on its outer end. The element that generates reciprocating movements is the movable section of the boom, coupled with the end of the movement transmission cable and having a handle at its end. Part of the transmission of motions is coaxially located inside the boom and its sheath is conjugated with the supporting section of the boom. In general, the transmission of movements from the movement motor to the stop is located inside the seat and, in its continuation, is located inside the stop and the arrow with the slider. In order to avoid possible bending of the sections of the cable outside its sheath, in the motion engine and in the boom with the slider “visible”, that is, outside the sheath, the ends of the cable are made rigid or, equivalently, replaced by equal-sized straight rods at a length of the cable from its ends that is not less than the maximum its length outside the braid when the motion motor is running.

To increase the stability of the position of the pelvis of the body on the seat, there are removable railings on the outer side ends of the seat, which are installed depending on the preferences of the user of the device. To protect against the environment and facilitate sanitation, the stop and the arrow with the slider are enclosed in a hygienic elastic shell, over which a replaceable cover is put along the arrow with the slider, for example, a medical rubber fingertip.

The proposed device for fragmentation of a fecal plug in the distal part of the human rectum by pressing on the rectum in its distal part through the soft tissues of the body in the area of the gap between the coccyx and the anus consists of: an element fixed relative to the pelvis of the human body in the form of a seat associated with the toilet (1) (2) with a hole (3) in it; a movable element in the form of a slider (4) with a pommel (5); motion drive, consisting of a reciprocating motion motor (6) and a motion transmission (7) that transmits motions from the motion motor to the slider; stop (8) in the form of a console of three links connecting the telescopic boom with the slider with the seat; removable railings (9) on the outer end of the seat (one shown).

The transmission of movements consists of a steel flexible cable (10) movable in an elastic longitudinally rigid steel wire braid (11). At the end sections of the cable in the motion engine and at the slider, respectively (12) and (13), the cable at its length from its ends, not less than its maximum length at these ends outside the sheath when the motion engine is running, is made rigid in the form of replacing these sections cable equal to these sections of the rods.

The movable element is made (Fig. 3, Fig. 4) as a slider in the form of a movable section (4) in a tubular retractable two-section telescopic boom, the other, supporting, section (14) of which, as a guide of the slider, is connected by its supporting end with a stop (8) of three links with a seat. The movable section is made sliding on the support. For comfortable contact with the body, a pommel (5) in the form of a segment of a ball is placed on the end of the slider, conjugated with the end of the slider by its base and with its smooth surface, smoothly passing to the surface of the end of the slider. The transmission of movements is located coaxially inside the support section and the end of the cable (13) is connected to the slider at its end from the inside. The end of the motion transfer braid is placed flush with the inner end of the support section.

The first stop link from the seat is made in the form of a tubular retractable two-section telescopic boom, the outer section (15) of which is rigidly connected to the seat, and the inner (16) one end is placed in the seat, and the other outside it is hinged with the possibility of fixation associated with the end (17) second link. Sections of the first link ((15) and (16)) are connected to each other by a collet connection with a clamping nut (18). The second link of the stop with its other end is also pivotally connected (19) with the possibility of fixation with the end of the third, last, link of the stop. The second and third links of the stop are made of a tubular structure. The last stop link with its free end is hinged with the possibility of fixation (20) with the end of the support section (14) of the boom with the slider (4).

The muscular motor (Fig. 5) for reciprocating movements is made in the form of a retractable tubular two-section telescopic boom with a handle (21) at its end. The support section (22) of the boom is associated with the seat, and its movable section (23), which is slidable onto the support section, is connected to the end of the motion transmission cable through the handle. The transmission of movements is coaxially placed in the support section and is conjugated with its braid

(24) with her. The end of the braid is placed flush with the inner end of the support section. In the motion engine, it is possible to adjust the length of the cable outside the sheath from the handle to the beginning of the sheath in it, which determines the maximum amplitude of the slider pressing on the body. Adjustment is carried out by moving the sleeve hinged to the end of the cable

(25) threaded and slotted in the threaded hole in the handle with the sleeve locking with the screw (26). The movement transmission sheath is connected to the seat by clamping bars (27) at the stop entry and approximately in the middle between the movement engine and the stop entry. The clamps are loosened when setting up the device with their subsequent fixation.

The device for fragmentation of the fecal plug in the distal part of the rectum is used as follows.

Due to the variety of seat shapes and some individual anatomical features of the hip part of the body in different people, before using the device, its individual adjustment is necessary.

For deformation of the fecal column in the rectum (Fig. 6, Fig. 7), the most effective action of the force Pn of pressure across it, and since in the area of the gap between the coccyx and anus, the skin of the body and the wall of the rectum are located almost equidistantly, it will be most effective for fragmentation and orthogonal to the skin of the body direction of the pressing force of the slider. The pressure of the slider occurs along its axis, which means that the location of its axis should be orthogonal to the skin of the body.

When pressing on the skin, a funnel-shaped indentation hole is formed on it. If pressure occurs near the tip of the coccyx, then on the wall of the depression socket closest to it, the skin of the body undergoes much greater stretching than on the opposite wall of the hole, and this is fraught with injury to the skin of the body. When pressing near the anus, the area of influence of the pressure force on the fecal plug decreases or the end of the slider slides through the anus to the fecal mass at the anus. Therefore, the most acceptable place for pressing the slider on the skin can be considered the middle of the gap between the anus and the nearest orthogonal projection of the apex of the coccyx onto the skin of the body.

An analysis of the topology of the human body showed that a flat area of skin between the coccyx and anus (interval AB in Fig. 6, represented by segment AB in Fig. 7, where the point "O" is the middle of segment AB) in different people, depending on their individual characteristics of the anatomy of the pelvis located mainly at an angle α (Fig. 7) from 120 to 150 degrees to the sagittal axis Co in the median sagittal plane of a person. Consequently, all people have their own optimal angle β of the direction of the pressing force Рн and it can lie on average in the range from 30 to 60 degrees from the Co axis. It is not easy to accurately measure the angle of inclination of the segment AB, therefore, it is permissible to first take the value of the angle β of pressure by the slider equal to 45 degrees to the Co axis with further, if necessary, its adjustment in the practice of using the device. For example, changing the angle of the pressure force Pn of pressing with a slider from 0 to 15 degrees from orthogonal to the skin reduces the normal component of the pressure force on the rectum by 5%, which is very uncritical for this process.

The starting position before using the device is a stable, immobile position of the body pelvis on the seat, for example, in the position of defecation, when the end of the slider, at its lowest position in the boom, touches or slightly rests against the skin of the body in the middle of the gap between the coccyx and anus, with the axis of the boom orthogonal to the skin with slider.

The position of the slider and its end is set by the configuration of the mutual arrangement between the links of the stop and the boom with the slider, as well as, within certain limits, by the position of the movable section of the first link of the stop. The pressure of the slider on the body is carried out by the action of muscle force on the handle of the motor of movements in the axial direction, which also sets the amplitude and force of the pressure.

As the device is used, the user develops the character of pressures acceptable to him by the handle of the movement engine, including setting the magnitudes of the amplitude and force of pressures.
