Problems solved by technology
However, common neck incision and oral tracheal intubation techniques can cause greater damage to the trachea, which can easily cause increased airway secretions. After surgery, it is difficult for mice to resume self-guided breathing, and airway blockage often leads to death.

Embodiment Construction
[0018] As shown in the figure, the mouse ventilation device of the present embodiment includes a mouse head holder 1 and a nasal mask 2, and the mouse head holder includes two handles 11 arranged in parallel and arranged on two handle ends. The arc-shaped pressing bar 12 at the top; in this embodiment, the plane where the two parallel handles are located is perpendicular to the plane where the arc-shaped pressing bar is located. The nasal mask includes a cylindrical nasal mask body 21 , and the cylindrical nasal mask body 21 is arranged on the mouse head holder in a manner that can slide axially along the handle. The specific implementation plan is: the nasal mask also includes a flange 22 arranged at one end of the nasal mask body, and two through holes 23 are arranged on the flange. When in use, anesthetize the mouse 6 and lie supine with a mouse head holder to fix the head, cover the nose of the mouse with a nasal mask, and then connect it to a ventilator for ventilation. A...

The invention discloses a mouse aeration device which comprises a mouse head fixing unit and a nose cover, wherein the mouse head fixing unit comprises two parallel handles and arc compression bars which are arranged at the ends of the two handles; and the nose cover comprises a cylindrical nose cover body which can be arranged on the mouse head fixing unit in a manner of sliding along the axial direction of the handles. During the use, a mouse is narcotized and then lies on the back, the head of the mouse is fixed by the mouse head fixing unit, the nose of the mouse is covered by the nose cover and then the nose cover is connected to a respirator for aeration; after the aeration, the lung of the mouse dilates to indicate that the aeration is normal; and after adjustment of the frequency of the respirator, related operations can be carried out. Experiments prove that by using the mouse aeration device provided by the invention, the trachea injuries of mice can be decreased, the death rate of the mice in the experiment processes can be greatly reduced and the success rate of the experiments can be improved.
Description
technical field [0001] The invention relates to a medical experiment equipment, in particular to a ventilating device which does not need trachea intubation during artificial respiration of mice. Background technique [0002] Mice are an important experimental model for medical research. This model can simulate the diagnosis, treatment and related mechanism research of various diseases, and has very important use value. Artificial respiration is an important support method in the process of making mouse animal models. However, common neck incision and oral tracheal intubation techniques can cause greater damage to the trachea, which can easily cause increased airway secretions. After surgery, it is difficult for mice to resume self-guided breathing, and airway blockage often leads to death. [0003] In view of the above deficiencies, it is necessary to provide a ventilation device for mice that reduces tracheal damage and related mortality in mice. Contents of the inventi...
