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 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.
