Description

Mouse laryngoscope with light source and intubation tube fixing device

Technical Field

The utility model relates to an experimental device technical field, concretely relates to mouse laryngoscope and intubate fixing device from taking light source.

Background

In mouse experimental models of myocardial infarction, lung perfusion injury and the like, a breathing machine is required to maintain the mouse to breathe in an open chest state, or a drug delivery channel is required to be established to a lower respiratory tract through a trachea, and the trachea cannula of the mouse is an important operation link for establishing the experimental models. However, because the mouse is small in size, the larynx of the mouse can be quickly and simply exposed through the oral cavity, the illumination of the laryngeal part of the pharynx can be realized in a limited space, and the trachea cannula is difficult to insert into the trachea of the mouse under the visual observation of an experimental operator; in addition, the trachea cannula is not easy to fix after being successfully inserted, the trachea cannula is easy to slip in the experimental process, and a mouse with a chest opening is easy to die due to the interruption of oxygen supply in a short time after the trachea cannula slips. These problems make tracheal intubation and fixation of mice a "rate-limiting" step in such experiments.

Most laboratories do not have special device to the mouse intubate at present, use vascular forceps or tweezers to replace the laryngoscope, and it is extremely inconvenient to operate, and is great to the mouse injury, and needs extra preparation to penetrate the illumination of penetrating from the outside penetration of throat of stronger high-power light source, energy-concerving and environment-protective inadequately. The fixing of the insertion tube is completed by using adhesive tapes, so that the operation is not easy, the fixation is not firm enough, the slipping is easy, and a large amount of adhesive tapes are consumed.

And the existing small animal laryngoscope in the market is suitable for various animals with different body types, such as mice, rats, guinea pigs and the like, has larger volume, is not suitable for mouse tracheal intubation and is very heavy, and the intubation is easily taken out when the laryngoscope is taken out after the intubation is finished, so that the intubation failure is caused. In addition, the laryngoscope only has a single blade, can not effectively fix the upper teeth of the mouse, fully exposes the throat and still needs other instruments and operations.
