Abstract
The utility model relates to a mouse oral trachea cannula which at least comprises a metal body tube core (1), a tube core holding end (2), a catheter (3) and a tube base (4). The metal body tube core (1) and the tube core holding end (2) form a direction and angle control cannula guide structure, the tracheal catheter (3) and the tube base (4) form a ventilation structure, the metal body tube core (1) is embedded in the tracheal catheter (3), the tube core holding end (2) is embedded in the tube base (4), and the tube base (4) is connected with a breathing machine catheter. The mouse oral trachea cannula has the advantages that the hardness and angle of the metal tube core are used for controlling the inserting direction and angle of the trachea cannula, the smooth catheter with relative low hardness is used as a ventilation pipeline, so that the trachea larynx and the inner wall of the cannula can be effectively protected, and effective ventilation is achieved. Compared with a traditional method, the mouse oral trachea cannula is simple, convenient to manufacture and control, and good in effect.
Description
Technical field
This utility model relates to a kind of intubate, particularly a kind of its mouse oral tracheal intubation.
Background technology
Mice is the laboratory animal of commonly using now, in the medical scientific field, be with a wide range of applications, thereby the human diseases model that utilizes the means intervention experiment mices such as medicine, operation, genetic modification to build is widely used in medical scientific.Mice open chest surgery is in the past often used tracheotomy (traceotomy), sets up extra respiration channel, to carry out assisted respiartion.Conventional tracheotomy need be after anesthetized mice, get dorsal position, cervical region is shedded, from the thyroid cartilage lower edge, to approaching, cut at the suprasternal fossa place, tissue before the blunt separation trachea, expose trachea, in thyroid cartilage lower end T-shaped tracheostomize cartilage, after inserting endotracheal tube, silk thread ring-type ligation trachea and the endotracheal tube that is applicable to bore, carry out breathing machine ventilation in skin degerming, neck center, covers sterile gauze in case infect and adhesion simultaneously; Operation is cut off ligation and is first withdrawn conduit, sews up trachea, flesh layer, subcutaneous tissue and skin histology before finishing, finally also need to sterilize infection and analgesia are processed.This traditional tracheotomy expends time in for a long time, and wound is large, and operation efficiency and postoperative laboratory observation are had a great impact.
Summary of the invention
The purpose of this utility model be to provide a kind of can be without wound, short consuming time, safe and reliable its mouse oral tracheal intubation.
The purpose of this utility model is to realize like this, a kind of its mouse oral tracheal intubation, at least comprise: metallic object tube core, tube core holding end, conduit and base, metallic object tube core and tube core holding end form direction and angle is controlled the intubate guide frame, and endotracheal tube and base form ventilation device; The metallic object tube core is nested in endotracheal tube, and the tube core holding end is nested in base simultaneously; Base is connected with the respirator conduit.
Described metallic object tube core is provided with core bar, and core bar is placed in conduit; Metallic object tube core afterbody is provided with cylindrical tube core holding end, and is placed in base; Conduit is fixedly connected with base, and in through hole is arranged, the through hole two ends communicate, and form the guide pipeline structure.
The long 30mm of described metallic object tube core, external diameter 0.5mm; The long 25mm of tube core holding end, diameter 5mm; The long 25mm of conduit, internal diameter 0.6mm, external diameter 0.9mm; The long 15mm of base, minimum diameter 0.6mm, maximum inner diameter 2.2mm.
The core bar of described metallic object tube core is placed in conduit, and is shorter than conduit 1 ~ 2mm, and its head end 5 mm places are 5 ° of arc-shaped bends.
The utility model has the advantages that: hardness and the angle of utilizing metal die; control direction of insertion and the angle of tracheal intubation; utilize level and smooth and conduit that relative hardness is lower as breather line, thereby guaranteed the effective protection to trachea throat and inner surface of trachea, the enforcement effective ventilation.Than traditional method, this utility model is simple for production, is convenient to control, respond well.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is this utility model embodiment overall structure schematic diagram;
Fig. 2 is this utility model embodiment each several part structural representation.
In figure, 1, the metallic object tube core; 2, tube core holding end; 3, conduit; 4, base.
The specific embodiment
As illustrated in fig. 1 and 2, a kind of its mouse oral tracheal intubation, at least comprise: metallic object tube core 1, tube core holding end 2, conduit 3 and base 4, metallic object tube core 1 and tube core holding end 2 form direction and angle control intubate guide frame, and endotracheal tube 3 and base 4 form ventilation devices; Metallic object tube core 1 is nested in endotracheal tube 3, and tube core holding end 2 is nested in base 4 simultaneously; Base 4 is connected with the respirator conduit.
Described metallic object tube core 1 is provided with core bar, and core bar is placed in conduit 3; Metallic object tube core 1 afterbody is provided with cylindrical tube core holding end 2, and is placed in base 4; Conduit 3 is fixedly connected with base 4, and in through hole is arranged, the through hole two ends communicate, and form the guide pipeline structure.
The long 30mm of described metallic object tube core 1, external diameter 0.5mm; The long 25mm of tube core holding end 2, diameter 5mm; The long 25mm of conduit 3, internal diameter 0.6mm, external diameter 0.9mm; The long 15mm of base 4, minimum diameter 0.6mm, maximum inner diameter 2.2mm.
The core bar of described metallic object tube core 1 is placed in conduit 3, and slightly is shorter than conduit 31 ~ 2mm, and its head end 5 mm places are 5 ° of arc-shaped bends.
In the present embodiment, metallic object tube core 1 has formed solid structure and has controlled the intubate direction, control tube core holding end 2 by thumb and forefinger, and utilize 5 ° of arc-shaped bends of metallic object tube core 1 head end, guarantee the head end deflection mice veutro face of conduit 3 in the intubate process and enter smoothly in trachea; Extract tube core 3 after intubate success, between conduit 3 and base 4, through hole is connected, formation breather line structure, and base 4 is connected with the respirator conduit, and communication conduit 3 is connected with the ventilation of respirator.After mechanical ventilation, disconnection base 4 is connected with respirator, extracts conduit 3.
