Description

The invention relates to medicine, in particular to devices for administering drugs to the hollow organ, and is used, for example, for rectal dosed delivery of drugs to the rectum or other place of the human body.

Currently known rectal, vaginal and other suppositories intended for dosed delivery of drugs into the hollow organ ("Brief Medical Encyclopedia" Volume 2, p. 57, article "Dosage Forms", ed. "Soviet Encyclopedia", 1989). Such candles have a solid wax carrier with medications intervened in it. The candle is inserted into the rectum with the help of a finger and after some time it melts inside this intestine, and the medicine dissolves, causing the necessary therapeutic effect. The disadvantage of the candle is that when you enter the candle with your finger, it is impossible to accurately determine its location inside the rectum. All this reduces the effectiveness of treatment. In addition, wax has a high cost, so the use of disposable candles is economically disadvantageous. It is known the introduction of drugs into the human body in the form of ointments from tubes using cannulas according to the patent of the Russian Federation (RU No. 2143288 C1, published on 12.27.99). The main disadvantage is the inaccuracy in the delivery of drugs to the diseased organ. In addition, in the tubes and cannulas after the procedure, many unused ointments remain.

As a prototype, a device for the metered administration of therapeutic ointments into the rectum anus according to the patent of the Russian Federation (RU No. 22204422 C1, published on 05/20/2003) containing a sleeve with a cavity for the ointment and a piston rod for its expulsion is considered. The rear end of the sleeve is made in the form of a collet with spring petals, compressing the piston rod. On the surface of this piston are risks and numbers to fix the position relative to the anus. At the front end of the sleeve there are bypass openings connecting the cavity of the sleeve with the atmosphere. The main disadvantages of the device are the inaccuracy of drug delivery to the diseased organ and the uneconomical consumption of a large amount of ointment, since ointments are distributed throughout the cavity of the rectum, and not near the treatment site. This is especially unacceptable when using potent drugs, such as bee venom. The disadvantage is the impossibility of prompt simultaneous dosage of several drugs in one procedure. In addition, in the cavity of the sleeve after the procedure, many unused ointments remain.

The present invention solves the problem of accurate, metered and economical delivery of medicinal ointments to any area of a hollow organ of a person with a device having the simplest design. The simultaneous operational dosage of several combinations of drugs and their delivery to the right place during one procedure is possible. All this significantly increases the effectiveness of treatment.

To achieve this technical result, in the present invention, the sleeve inserted into the hollow organ is made in the form of a solid rod on which cavities for therapeutic ointments in the form of recesses are made from the outer cylindrical part. The rear end of the shaft has a reduced diameter compared to the maximum diameter of the shaft. A guide tube is put on this end with a loose fit, the outer diameter of which does not exceed the maximum diameter of the sleeve. Numbers are evenly applied along the length of the tube, and a flexible cord with a round stop is fixed at the rear end of the rod.

The limiter can be made at the rear end of the rod after the cylindrical part with a reduced diameter in the form of a rigid limiter, the maximum diameter of which exceeds the maximum diameter of the rod by at least 2 times.

The rod may be made of ebonite.

Distinctive features of the proposed rod dispenser of drugs (SDL) from the above known, closest to it device for the dosed introduction of therapeutic ointments into the rectum anus, is that the sleeve is made in the form of a solid rod, and on it from the outer cylindrical part (and not inside it, as in the prototype) cavities for therapeutic ointments in the form of recesses were made. A distinctive feature is that the rear end of the rod has a reduced diameter compared to the maximum diameter of the rod. A guide tube is put on this end with a loose fit, the outer diameter of which does not exceed the maximum diameter of the sleeve. Numbers are evenly applied along the length of the tube, and a flexible cord with a round stop is fixed at the rear end of the rod.

Due to the presence of these signs, the core with therapeutic ointments in the recesses can be accurately and painlessly inserted into the hollow organ. The rear end of the rod has a reduced diameter compared to the maximum diameter of the rod, which allows you to put on this end with a loose fit guide cylindrical tube. After the introduction, the tube is freely removed, leaving the shaft with therapeutic ointments inside the hollow organ for a long time, during which the ointments diffuse to the sore spot, being in close proximity with it. A flexible cord with a round stop attached to the rear end of the shaft prevents the entire cord from entering. The limiter also serves to remove the rod from the body after the procedure. The numbers, applied evenly along the length of the tube, serve to accurately record the position of the rod in the hollow organ.

A rigid limiter can be made at the rear end of the rod with a maximum diameter exceeding the maximum diameter of the rod by at least 2 times. Such a size does not allow the entire stem to go inside the hollow organ. The rigid limiter also serves as a fixator for the position of the rod relative to the treatment site and a grip for extracting SDL from the body. With this design, SDL does not need to use a tube to insert it into a hollow organ. The disadvantage is that the position of the limiter is fixed relative to the rod, and therefore, in each case, it is necessary to individually manufacture SDL of a certain length for each person or disease, i.e. SDL is becoming less universal. Removal from the rectum of the rod is carried out for this hard limiter. In addition, with a prolonged (more than 4 hours) presence of such a rod in the rectum, the compressing muscles of the anus can relax, which is an undesirable factor in the treatment of diseases of the rectum.

The rod may be made of ebonite. Such an ebonite core gives an additional therapeutic effect, since ebonite has healing properties (see Rukin M.D., Yasianov N.A., Ageeva S.F. The healing properties of stones and metals, NIVA RUSSIA publishing house, Moscow, 1999) .).

The proposed SDL is illustrated by the drawings shown in figures 1, 2. A General view of the SDL is shown in figure 1. SDL contains a cylindrical rod 1, the front end 2 of which is spherical, and the rear end 3 has a reduced diameter compared to the maximum diameter of the rod. A flexible cord 4 with a stopper 5 is fixed at this end. Recesses are made on the rod in the form of wave-shaped annular grooves 6. Here, a guide tube 7 is put on, put on with a loose fit on the rear end of the rod and on which are marked 8.

Figure 2 shows an option SDL with a rigid stop 9 at the rear end of the rod. The functioning of SDL can be described when used to treat prostatitis. Before use, grooves 6 are filled with medicinal ointments. Then, a guide tube 7 is put on the rear end of the rod 3 with a loose fit. The rod and the tube are inserted into the rectum up to the number marking the insertion depth corresponding to the distance from the anus to the prostate gland (prescribed by the attending physician). This allows, in the absence of a doctor (an outpatient clinic, at home), to always accurately install the rod in the right place of the rectum relative to the prostate. The tube is removed, while the limiter 5 is located outside the body. Rod 1 remains in the rectum for the time prescribed by the attending physician (approximately 4-8 hours, possibly overnight). Drugs from the grooves 6 diffuse through the walls of the rectum to the prostate located nearby, and treat it. After the procedure and complete diffusion of the drug, rod 1 for the limiter and flexible cord is removed from the rectum.

Drawings were developed for the proposed SDL, samples that passed the stage of medical research were made, and mass production is being prepared.

The use of SDL has shown in practice its therapeutic effectiveness, ease of use and cost-effectiveness in the prevention and treatment of cracks, cysts and polyps of the rectum, as well as hemorrhoids. The special effectiveness of SDL is shown in the treatment of prostatitis, since when it is introduced into the rectum, the closest contact with the prostate is ensured. Repeated use of the rod with medicinal ointments gives a significant economic effect compared to the use of disposable candles from expensive wax.
