Abstract

An endotracheal intubation tool includes a guide cannula. A conical sleeve port is formed in one end of the guide cannula. A guide wire handle is arranged in the guide cannula. A remaining needle cannula is connected with the conical sleeve port. A flexible guide wire is connected to the guide wire handle. The guide wire handle is pushed to enable the guide wire to penetrate through the remaining needle cannula, the remaining needle cannula is slightly connected with the front end of the guide cannula, and the guide cannula is held by the right hand. When the glottis is opened, the guide wire is quickly inserted into the trachea, the guide cannula enters the trachea along the guide wire via the glottis, and the guide wire is withdrawn after the guide cannula enters the trachea. The endotracheal intubation tool is simple in structure, easy and convenient to operate, high in success rate and good in repeatability.

Description

A kind of tracheal Intubation Device

Technical field

The invention belongs to intubation technique field, be specifically related to a kind of tracheal Intubation Device.

Background technology

Traditional mice tracheal intubation method is broadly divided into two kinds: have wound intubation and noinvasive intubation.

Wound endotracheal intubation is had namely to adopt the method for tracheotomy, although easier, larger to wounds in animals, and the method may cause bleeding and airway obstruction even trachea tear, mortality of animals is higher, and the infection etc. that may cause can affect the observation to result of study, and repeatability is poor.

The method of noinvasive tracheal intubation has blindmate method, direct-view tracheal intubation:

Blindmate method needs repeatedly to try to insert, and one-time insertion success rate rate is lower, very easily causes bottleneck throat to damage and laryngeal edema, is unfavorable for the recovery of animal, although required apparatus is simple, higher for operator's technical requirement, is unfavorable for grasping.

Namely animal oral cavity illuminates by external light source by direct-view tracheal intubation, murine oral is opened, push open after tongue body appears glottis, tracheal intubation is completed under people's direct-view, because mouse breathing frequency is very fast, oral cavity is comparatively narrow and small, glottis position is higher, rapidly opened and closed without due to glottis during guide cannula, it is more difficult that conduit enters glottis, undue force may cause bottleneck throat to damage, or enter esophagus by mistake, Part Methods adopts the rigid nook closing member of remaining needle as guiding, its shortcoming is that rigid nook closing member may cause the damage of surrounding tissue when cannot disposablely successfully insert, cause bleeding, or rigid nook closing member causes trachea damaged.Visual cannulation accuracy rate promotes to some extent, but the technical requirement needing operator certain, and repeated intubation easily causes laryngeal edema, Airway damage, secretions increase even animal dead, poor repeatability.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of tracheal Intubation Device, having that structure is simple, easy and simple to handle, success rate is high and the feature of favorable repeatability.

To achieve these goals, the technical solution used in the present invention is: a kind of tracheal Intubation Device, includes guide thimble, and one end of guide thimble is provided with taper running-on; Seal wire handle is provided with in guide thimble; Remaining needle sleeve pipe is connected with taper running-on; Seal wire handle is connected with flexible guidewire.

Described flexible guidewire enters in guide thimble from taper running-on, and is connected with seal wire handle.

Beneficial effect of the present invention:

1) design science is reasonable, meets physiology: this tracheal Intubation Device simulates person's windpipe intubation way, more science, meets physiology.

2) easy and simple to handle, success rate is high: the lower operation of direct-view, can accurately determine glottis position, seal wire guides can reduce enter the esophagus by mistake probability to greatest extent, lower to technical requirement, training can grasp the method a little, and skilled grasp within rear 30s can complete intubate, and one-time insertion success rate rate can obviously promote, can more than 95% be reached.

3) reduce damaging surrounding tissue; little on animal impact: conduit have employed flexible guidewire and guides; this seal wire runs into obstacle and can bend; seal wire can be prevented for the damage of bottleneck throat tissue; effectively can protect trachea after entering trachea simultaneously; avoid the generation of trachea breakage; and seal wire is very thin; by also can avoid to greatest extent during glottis damage; overcome the drawback that the traditional methods such as hemorrhage, bottleneck throat tissue injury, infection exist; animal recovers fast, little on result of study impact.

4) favorable repeatability: apply this tracheal Intubation Device accuracy higher, and it is little for wounds in animals, complication is few, very micro-on animal recovery impact, and can not by the impact of operation last time when again carrying out tracheal intubation, can tracheal intubation be repeated and obvious impact can not be caused on animal, for the carrying out of follow-up study provides a great convenience.

5) be easy to make, with low cost, the material adopted in this device all can conveniently obtain, and manufacture method is simple, processes without the need to Special complex.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in further detail.

See Fig. 1,2, a kind of tracheal Intubation Device, includes guide thimble 1, and one end of guide thimble 1 is provided with taper running-on 2; Seal wire handle 4 is provided with in guide thimble 1; Remaining needle sleeve pipe 5 is connected with taper running-on 2; Seal wire handle 4 is connected with flexible guidewire 3; Seal wire handle 4 is connected with flexible guidewire 3.

Described flexible guidewire 3 enters in guide thimble 1 from taper running-on 2, and is connected with seal wire handle 4.

Operation principle of the present invention is:

After mouse anesthesia success, get dorsal position, head is towards operator, mice front tooth is fixed with rubber band, operating board is raised, angle about at 45 ° with plane, light source is positioned over and is about 5cm place apart from mice skin of neck, Mus tongue is involved to the left corners of the mouth of mice, the little spatula of 145 ° of angles is become slightly firmly upwards to be retracted by tongue body with front end, make a mouthful axis, pharynx axis, larynx axis is in alignment, visible glottis is with breathing folding in transmitted light, promote seal wire handle by flexible guidewire through remaining needle sleeve pipe, remaining needle sleeve pipe is engaged with sheathed catheter front end gently, the right hand holds sheathed catheter, when glottis is opened, rapidly flexible guidewire is inserted in trachea, sheathed catheter enters trachea along flexible guidewire through glottis, after sheathed catheter enters, exit flexible guidewire, connect respirator, observe thorax fluctuating situation, observe intubate effect.
