Drain pipe for nonauthoritative drainage and aeration of the maxillary sinus
(57) Abstract:The invention relates to the eye, in particular for the treatment of sinusitis and after radical surgery of the maxillary sinus. The technical result of the invention of improving the design of drainage pipes, improving the quality of treatment. Drain pipe consists of two hollow tubes made of inert polyethylene, one of which is longer for forced drainage has a locking part in the form of bumps made 1/3 of its length, and the second for non-aeration - fully Gavrilovna. 1 Il. The invention applies in otolaryngology, in particular for the treatment of sinusitis and after radical surgery (RO) on the maxillary sinus (HFI).Now for drainage HFI used both metal and polymer drainages different designs. Known analogues.with. 1321423 the USSR, and.with. 1595531). Metal drainage is a gross foreign body and can cause bedsores, and his sudden shift when the push or kick can lead to perforation of the orbital walls, in addition, is a long one-sheet tube often becomes clogged with clots of mucus and blood and sluit in creating long nonauthoritative drainage and aeration HFI in the treatment of sinusitis and after RO HFI and the creation of persistent fistula in a natural hole.The prototype is a drainage tube that is described in and.with. 1595531 stainless steel 30ch13 (h) or 40h13 (h) GOST 5632-72, length 4 cm, diameter 2 mm Is a cylindrical tube with a cutting edge and drainage holes at the distal end, which is put on the needle Kulikovskii and pierce bone HFI endonasal. Irrigation and introduction of medicinal solutions carried out using a commercially available polyethylene catheter subclavian vein with an outer diameter of 2 mm, which is placed in the drain tube.The disadvantages of the prototype.Metal drainage is a gross foreign body and can cause bedsores, and his sudden shift when the push or kick can lead to perforation of the orbital wall, besides being a long one-sheet tube, often clogged with clots of mucus and blood and is used only for forced drainage and forced aeration HFI. For administration of medicinal solutions additionally use a polyethylene catheter subclavian vein with an outer diameter of 2 mm, which may not create a strong enough stream for washing HFI. In addition, the drainage cannot be applied after RO HFI for POPs and drainage tube, improving the quality of treatment.The aim is achieved in that for the treatment of sinusitis and postoperative management after RO HFI use the drain tube for forced drainage, which additionally attach the tube to a nonauthoritative aeration of the maxillary sinus (DTA). DTA is made of 2 flexible hollow tubes of inert polyethylene. Tube 1 for forced drainage is designed for washing and administration of medical solutions HFI, length 10 cm, diameter 0.5 cm, the locking part Gavrilovna 1/3 from the end that is inserted into HFI, tube 2 for nonauthoritative aeration HFI, length 1 cm, diameter 0.5 cm, fully Gavrilovna. Corrugated part necessary to give the desired configuration in the nasal cavity and fixing the tube in the bone wall.DTA is used as follows. After enlargement natural orifice in any way, in the treatment of sinusitis or after RO HFI is inserted into the hole DTA side where the tubes 1, 2 are fixed corrugated part 3 in the bone wall. Protruding from the nasal cavity part of the tube 1 is cut. Through the tube 1, as necessary, washed or injected drug solution, and through Any patient, and to create a persistent fistula leave for a period of not less than 10 days.The advantage of the proposed drainage tube for forced drainage and nonauthoritative aeration HFI is that it consists of two flexible hollow tubes. One of the tubes 1 flushes the HFI and enter drug solutions at any time, without resorting to additional devices, while the diameter of the tube allows you to create the necessary pressure jet for rinsing HFI. The presence of the second tube 2, shorter than tube 1, allows natural nonauthoritative aeration HFI. The presence of the corrugated portion 3 in both tubes 1 and 2 ensures reliable fixation in the bone wall. Because the drain pipe is made of inert polyethylene, it is a easy design, which even in the case of shifting from shock or impact does not lead to perforation of the orbital wall. In addition, the fixing part 3 of the drainage tube in the form of the corrugation allows you to create persistent fistula in a natural place. Thus, using the proposed design of the drainage tube increases the quality of treatment, reduced invasiveness. Drain pipe for prinuditelnogo to the tube forced drainage attach the tube to a nonauthoritative aeration, when this tube for forced drainage has a locking part in the form of bumps on 1/3 of its length from the end that is inserted into the maxillary sinus, and the tube for nonauthoritative aeration fully Gavrilovna.
SUBSTANCE: method involves conducting bougie through the liver. Flexible tube is attached to its end and set in bile ducts. Flexible radio-opaque conductor is introduced through the flexible tube. The tube is removed. Draining tube is introduced along the conductor from porta hepatis to its diaphragmatic surface into the ducts to be drained.
EFFECT: reduced risk of traumatic complications.
SUBSTANCE: method involves puncturing pyogenic abscess cavity under ultrasonic control with draining tube left therein. Laparoscope connected to monitor unit is introduced into abscess cavity. One of introduced drains is set in upper point of the cavity and the other one in lower point. The abscess cavity is filled with ozonized solution to 2/3 of its volume and bubbled with ozone-oxygen mixture during 2-3 min changing the solution until it becomes transparent. The emptied cavity walls are treated from distance of 3-4 cm with laminar airflow heated to 38-40°C under pressure of 1-1.5 atm during 2-3 min. Next to it, the cavity walls are irradiated from distance of 2-3 cm with non-coherent red light during 2-3 min per each area.
EFFECT: improved safety conditions and healing quality.

SUBSTANCE: device has suction tube having lateral openings and irrigation tube. The irrigation tube is connected to jet-action atomizer. The atomizer is hollow collapsible cylinder with holes. Ultrasonic radiator having conductor to ultrasonic frequency oscillator is available in the cylinder. The radiator and conductor enable one to introduce ultrasonic oscillations into antiseptic solution.
EFFECT: enhanced effectiveness of treatment.
SUBSTANCE: method involves puncturing pyogenic cavity with trocar having blunt obturator via skin incision made outside of abscess boundary having length equal to arthroscope diameter. Then, arthroscope is introduced and the cavity is filled with physiologic saline. Pyogenic cavity revision is carried out under arthroscope control, irrigation cannula is set, constant water medium is created. Arthroscopic mill on shaver handle is introduced via another skin incision. Non-viable tissues are removed with stage-by-stage hemostasis using endocoagulator. The cavity is healed. Perforated draining tube is set under arthroscope control. Tube ends are brought out through pierces outside of the cavity and sutured to skin. Active suction of wound exudates is carried out using closed vacuum drain system in postoperative period. The drainage is removed when cleaning the wound from wound microflora and single sutures are placed.
EFFECT: enhanced effectiveness of treatment.

SUBSTANCE: the present innovation deals with treating patients in case of destructive forms of pancreatitis. One should lance a gastro-colic ligament, mobilize splenic and hepatic angles of large intestine, tighten a middle colic artery, descend mesenteric root cross-sectionally against a colon, dissect parietal peritoneum along the upper and lower edges of pancreas to withdraw it into abdominal cavity, remove necrotized tissues. Then one should apply a rubber balloon with drainage tubes along its upper and lower edges into omental cavity: one balloon's end should be withdrawn through median wound, another one - through contra-aperture being 5 cm below a costal arch along median axillary line. The method suggested enables to form adequate access to patient's pancreas.
EFFECT: higher efficiency of drainage.
