Description

Plugging device convenient for children to use

Technical Field

The utility model relates to a medical treatment auxiliary instrument technical field, concretely relates to plugging device convenient to children use.

Background

The bronchus blocking device is mainly used for establishing single-lung ventilation, wherein the single-lung ventilation refers to selectively ventilating healthy lateral lungs and collapsing diseased lateral lungs during an open chest operation, and mainly aims to prevent the healthy lateral lungs from being polluted by secretion or blood drained from the diseased lateral, such as massive hemorrhage, septicemia, lung abscess and the like, and collapse the diseased lateral lungs to provide a good visual field for the operation. There are generally three common lung isolation techniques to provide single lung ventilation: 1. double lumen bronchial cannulas (DLTs) (suitable for left or right bronchial insertions to confirm an unobstructed airway in the left or right lung); 2. a bronchial occluder (BB); 3. single lumen bronchial tubes (ETs) (single lumen tubes disposed within the bronchi, artificial airways for lung isolation and single lung ventilation, elongated tubes, short cuffs). At present, the application of the bronchial occluder in the lung isolation operation is more and more extensive, and the bronchial occluder is inserted into a target lung section of a tracheal cannula under the guidance of a fiber bronchoscope and reaches a preset position, and then a saccule at the tail end of the bronchial cannula is inflated to achieve the purpose of occlusion and isolation. However, when the device is used for children at present, the existing bronchial occluder is too large, when the device is used for infants, because the tracheal catheter is thin, the bronchial occluder is not easy to pass through the tracheal catheter or occupy most of lumens after passing through the tracheal catheter to cause unsmooth ventilation, the existing bronchial occluder is a double-lumen tube, a hollow pipeline is convenient for discharging residual gas of the lung at the occlusion side to collapse the lung at the affected side, the other lumen is used for inflating the balloon to occlude the corresponding bronchus, the pressure of the balloon is difficult to control, the problem of incomplete occlusion due to too small pressure is easy to cause air leakage, the wall of the bronchial tube is damaged due to too large pressure, and the balloon which is expanded after inflation can return to the main airway to cause ventilation obstacle of the lung at two. Therefore, a new technical solution needs to be designed to comprehensively solve the problems in the prior art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a plugging device convenient to children use, its simple structure, convenient to use can effectively solve the children of being not convenient for that exists among the prior art and use, rub damage and silica gel sacculus gas leakage easily, the not tight problem of laminating.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the occluder comprises a tracheal catheter and a bronchial occluder, wherein the bronchial occluder comprises a cuff end and a piston end, the tracheal catheter comprises a catheter and a connector, the inner wall of the catheter is provided with a hole groove, the hole groove is arranged along the length direction of the catheter, the cuff end is arranged at one end, far away from the connector, of the catheter through an occlusion tube, and the piston end is arranged at one end, close to the connector, of the catheter through the occlusion tube; the cuff is a hemispherical balloon body, one side of the cuff, facing the blocking tube, is open, a through hole with the same pipe diameter as the blocking tube is arranged on the opposite side of the cuff and the blocking tube, and the blocking tube is connected with the through hole.

Further, the piston end is provided with a pointing card, the pointing card is triangular, and the pointing direction of the pointing card is arranged on the same side with the inclination direction of the cuff.

In a further proposal, the cuff is made of soft silica gel and the expansion diameter of the cuff is larger than the diameter of the bronchus.

The utility model discloses a pipe wall is embedded directly with the bronchus blanking plug, the lumen that furthest remains endotracheal tube guarantees the needs of oxygen suppliment and ventilation in the art to and solve the problem that the thick endotracheal tube that uses in order to use the bronchus blanking plug in the prior art causes the damage to the infant; in addition, the existing balloon structure is changed into a hemispherical cavity structure, so that the problems that the bronchial tube wall is damaged due to balloon inflation and the balloon is easy to slide and return to the main airway are solved.

Detailed Description

In order to make the objects and advantages of the present invention more apparent, the present invention will be described in detail with reference to the following embodiments. It is to be understood that the following text is only intended to describe one or several particular embodiments of the invention, and does not strictly limit the scope of the claims specifically claimed.

The technical scheme of the utility model is as shown in fig. 1, fig. 2, a plugging device convenient for children to use, including endotracheal tube and bronchus blanking plug, bronchus blanking plug includes cover bag end and piston end, endotracheal tube includes pipe 1 and interface 2, be provided with hole groove 5 on the inner wall of pipe 1, hole groove 5 arranges along the pipe length direction of pipe 1, cover bag end set up in the pipe 1 one end of keeping away from interface 2 through stifled pipe 7, piston end set up in the pipe 1 one end that is close to interface 2 through stifled pipe 7; the cuff end is provided with a cuff 6, the cuff 6 is a hemispherical balloon body, one side of the cuff 6 facing the blocking tube 7 is open, the opposite side of the cuff 6 and the blocking tube 7 is provided with a through hole 61 with the same pipe diameter as that of the blocking tube 7, and the blocking tube 7 is connected with the through hole 61; the utility model discloses combine bronchus blanking plug and endotracheal tube, adopt the embedded mode at the endotracheal tube pipe wall with bronchus blanking plug, remain endotracheal tube's lumen to the at utmost to guarantee the needs that the oxygen suppliment was ventilated in the operation, effectively solved the problem that infant's endotracheal tube does not have enough lumen space to put into bronchus blanking plug.

Specifically, the piston end is provided with a pointing card 4, the pointing card 4 is triangular, and the pointing direction of the pointing card 4 is arranged on the same side of the inclined direction of the cuff 6; the inclination direction of the cuff can be rapidly and accurately judged, and the cuff is ensured to accurately enter the bronchus on one side to be blocked; in the specific arrangement, an arrow can be marked on the pointing card, and the pointing card is not limited to a triangular structure.

As shown in fig. 2, the cuff 6 is made of soft silica gel, and the expanded diameter of the cuff 6 is larger than the diameter of the bronchus; the hemispherical cuff is adopted to replace the existing balloon, so that the problems that the balloon needs to be inflated after being used for a period of time, the operation is troublesome, the air passage is damaged by wrinkles after deflation are solved, and the problem that the air passage is blocked because the wall of the bronchial tube is damaged due to inflation of the balloon and the balloon is easy to slide back to the main air passage is solved; the utility model discloses a hemisphere cover bag utilizes the atmospheric pressure principle (after the hemisphere cover bag blockked up, block up in the bronchus of distal end and be located relative "low-pressure area", this moment this side communicates with each other through the atmosphere of stifled pipe with the piston end, atmospheric pressure is equated to pressure, hemisphere cover bag blocks up the endotracheal of near-end and is located relative "high nip", this moment this side communicates with each other through endotracheal tube and breathing machine return circuit, pressure is equated to mechanical ventilation pressure, because the effect of the pressure difference between them makes hemisphere cover bag expansion), can closely laminate with the air flue after the expansion, before not aerifing because its shape and size can get into the air flue fast, the fast of the intubate operation of being.
