Abstract

The utility model relates to a high-efficiency guiding device for a person which is difficult to be inserted with a catheter. The utility model solves the difficulties for people who need to be inserted with catheters, particularly a person with a high larynx, because the glottis of the person is unable to be exposed, or only a smaller gap is exposed, in such a case, the front end of the original endotracheal catheter seems thicker when catheterization or retrograde catheterization is carried out, the encountered resistance is larger, so that the catheterization can be failed and the tissue can be seriously damaged. The utility model overcomes the shortages by a guiding catheter core of which the front end is provided with a cone-shaped structure, an accompanied inflating catheter, and an accompanied guiding pipeline.

Description

Efficient difficult intubation conductor

This utility model belongs to once anaesthetizes articles for use, a kind of efficient difficult intubation conductor.

When implementing the intubate general anesthesia, normal owing to patient's larynx height, when glottis can't appear or only appear than small gap to patient, carry out intubate or retrograde catheterization in this case, it is very thick that the endotracheal tube front end just seems, the resistance that is run into is also quite big, often makes intubation defeat and tissue injury serious.

The purpose of this utility model is a kind of efficient difficult intubation conductor of design, when glottis can't appear or only appear than small gap, is inserted in the endotracheal tube, and intubate or retrograde catheterization are succeedd.

For achieving the above object, the following technical scheme of the novel employing of this reality:

Described efficient difficult intubation conductor, be to add a conical target seeker at former guide wire stamen front end, this target seeker front end is a solid plastic, the rear end is inflatable part, and be provided with inflating catheter and lead to inflatable part attached to outside the guide wire stamen, also have a guide duct by conical target seeker and attached to outside the guide wire stamen.

The utlity model has following superiority:

Because having adopted at former guide wire stamen front end, this utility model increases an approximate conical target seeker, and inflating catheter and retrograde catheterization guide duct arranged, can't appear or make when appearing running into the higher glottis of larynx than small gap, this conductor is passed airway, guide, at this moment the front end of endotracheal tube is a subconical target seeker and replaces, this target seeker front end cross sections is less, can be by appearing glottis than small gap, import in the trachea easily in the time of maybe can not appearing glottis, and the resistance that runs into is less, target seeker is with the guide duct of driving in the wrong direction, this conical target seeker easily is imported into trachea when carrying out retrograde catheterization, thereby makes difficult intubation smooth.

Below in conjunction with the description of drawings specific embodiment of the utility model:

Fig. 1 is the structural representation of efficient difficult intubation conductor

As shown in FIG.: 1. guide wire stamen 2. conical target seeker front end plastic caps 3. are target seeker rear end inflatable part 4. inflating catheters 5. gas-charging connections 6. retrograde catheterization guide duct

Described efficient difficult intubation conductor has overcome the deficiencies in the prior art, add a conical target seeker at conventional lead pipe stamen front end, by the solid plastic part of front end and the inflatable part of rear end, and inflating catheter and form attached to the outer retrograde catheterization guide duct of guide wire stamen by target seeker, this conductor is after inserting endotracheal tube, original pipe catheter proximal end oval head is replaced by a conical target seeker, this target seeker easily imports in the trachea, no matter be intubate under photopic vision, or at retrograde intubation, and tissue injury is little.

Claims

1, a kind of efficient difficult intubation conductor is made of of the present utility model being characterised in that guide wire stamen (1): described efficient difficult intubation conductor is that the front end at the guide wire stamen adds a conical plastic cap (2) inflatable part (3) thereafter and passes nearly conical plastic head attached to the inflating catheter outside the guide wire stamen (4) and constitute attached to the guide duct outside the guide wire stamen (5) gas-charging connection (6).
