Abstract

The utility model discloses a bronchial guide pipe for a right-side single cavity, which is composed of a tracheal inserting pipe joint, a tracheal guide pipe, a sleeve bag, a side hole, and an air valve. The utility model is characterized in that the side hole is arranged on the longitudinal line of the position of three o'clock of the cross section of the tracheal guide pipe; the length of an ellipse at a distance of 5 mm from the front side end of the side hole is from 12 to 15 mm; the transverse diameter is 7 mm. By adopting the utility model, right-lung ventilation can be effectively carried out, and ventilation insufficiency, atelectasis, and hypoxemia vicious circles which are caused by that when a guide pipe of the ordinary pipe carries out the right-lung ventilation, the guide pipe is blocked at the bronchial-shaped part of an upper lobe lung can be avoided. The utility model has the advantages of clinical practicality and low price, and is mainly suitable for the anesthesia of single-lung ventilation.

Description

Right single cavity bronchial catheter

This utility model relates to the anaesthetic apparatus in a kind of medical treatment, mainly is applicable to the anesthesia of thoracic surgery, is particularly suitable for the patient of left side open chest surgery.

The common single-lumen bronchial tube that in thoracic surgery, uses at present, block the right superior lobar bronchus opening part when doing the right lung ventilation easily, cause the superior lobe of right lung hypoventilation, do not open, and a series of vicious cycle by its caused hypoxemia, and double lumen endobronchial tube is at the imported product that is of clinical practice at present, every nearly 1,000 yuan RMB, the price height, increase financial burden gives treatment to a patient.

In view of last situation, the purpose of this utility model is to provide a kind of and does not block right superior lobar bronchus, and the relatively low right side single lumen endobronchial tube of price.

The purpose of this utility model is achieved in that this device is made up of tracheal intubation joint, endotracheal tube, cover capsule, side opening, fine duct, air valve, the tracheal intubation joint is the plug connector that duroplasts is made, top can connect anesthetic machine or respirator, the bottom is with endotracheal tube, endotracheal tube is made by PVC, the surface indicates scale, long 34-38mm, hold the about 45 of opening to the right, its transverse section 9 o ' clock positions are longer than 3 position 6mm, be endotracheal tube front opening about 45 of bowing, right side 6mm is longer than in the left side; On the vertical shape line of endotracheal tube transverse section 3 o ' clock positions, apart from its front side end 17.5mm place for the center of circle has oval side opening, the long 12-15mm of side opening, transverse diameter 7mm, apart from its distal edge 2mm place for the cover capsule, long 18mm; Have pore at the endotracheal tube middle part, the interpolation fine duct, it overlays on the endotracheal tube inwall, and the fine duct other end is connected to air valve, and air valve is anterior to be the capsule of getting a breathing space, but the rear portion gas injection.

This utility model compared with prior art, its side opening is on the ordinate of endotracheal tube transverse section 3 o ' clock positions according to 12 routine fresh right lung leaf excision specimen measurement result and the designs of compatriots' anatomic characteristic, is the ellipse in the center of circle apart from its front side end 17.5mm place, long 12-15mm, transverse diameter 7mm.This kind structure is compared with common endotracheal tube, can effectively carry out the right lung ventilation, block the right superior lobar bronchus opening part when having avoided doing the right lung ventilation, due to the superior lobe of right lung hypoventilation, do not open, and a series of vicious cycle by its caused hypoxemia, and have clinical practice, advantage such as price is low.

Accompanying drawing one is this utility model structural representation;

Accompanying drawing two is this utility model front-end architecture sketch map;

Further specify this utility model below in conjunction with accompanying drawing.

In conjunction with the accompanying drawings, this utility model by tracheal intubation joint 1, endotracheal tube 2, cover capsule 3, side opening 4, fine duct 5, air valve 6, form, endotracheal tube 1, the plug connector of making for duroplasts, top connects anesthetic machine or respirator, the bottom is with endotracheal tube 2, endotracheal tube 2 and is made by PVC, the surface indicates scale, long 34-38mm, front end is the about 45 of opening to the right, its transverse section 9 o ' clock positions are longer than 3 position 6mm, be that the endotracheal tube front opening is overlooked about 45, right side 6mm is longer than in the left side; On the vertical shape line of airway transverse section 3 o ' clock positions, apart from its front side end 17.5mm place for the center of circle has oval side opening 4, long 12-15mm, transverse diameter 7mm has pore, interpolation fine duct 5 at the endotracheal tube middle part, it overlays on endotracheal tube 2 inwalls, fine duct 5 other ends are connected to valve 6, and its front portion is the capsule of getting a breathing space, but the rear portion gas injection.

According to measurement result to 12 routine bright right lung leaf excision specimen, be that the right superior lobar bronchus transverse diameter is 9.87 ± 0.77mm, in conjunction with compatriots' anatomic characteristic, superior lobe of right lung is opened on right principal bronchus 21 ± 4.8mm place, the bronchus transverse diameter is 9 ± 1.2mm on the right lung, right lung main bronchus transverse diameter is 15 ± 1.7mm, bronchus length 18 ± 5mm in the middle of right, transverse diameter is 12 ± 1.3mm, and single chamber, design right side bronchus is oval to the side opening of superior lobe of right lung opening, and its transverse diameter is 7mm, long 12-15mm, concrete grammar is: transtracheal catheters transverse section 3 o ' clock positions are made a vertical shape line, on this line, open an oval side opening apart from its front side end 17.5mm place for the center of circle, in addition, endotracheal tube section 9 o ' clock positions are longer than 3 o ' clock position 6mm, and promptly the endotracheal tube front opening is overlooked and is about 45, and right side 6mm is longer than in the left side.

According to right principal bronchus length (male 21mm, women 19mm), design cover capsule is long to be 18mm, and its near-end is apart from side opening remote edge 2mm, and opening low gland capsule with height is the best.
