Description

FIELD OF THE INVENTION [0001] The present invention relates to an air intubation aid for a small animal, and an air intubation method using the same.

[0001] The present invention relates to a medical apparatus for small animals, and more particularly, to a small-sized animal airway intubating apparatus that can assist a small animal such as a laboratory animal when an intubation is performed for anesthesia, ≪ / RTI >

Many universities, hospitals or laboratories dealing with medicine, pathology or pharmacy use small animals such as laboratory mice for in vivo experiments. Experimental procedures include surgery and procedures. Anesthesia is performed for surgery and procedures. Anesthesia is performed by injecting an inhalation anesthetic through the airway, which is very difficult to determine if the airway is open because the laboratory rat is a small animal. When the airway is opened, a tube for administering an inhalation anesthetic should be inserted. Since the airway is small, it is difficult to confirm whether it is open or not, and it is also difficult to insert the tube when opening. Thus, the efficiency of experiments with small animals is greatly reduced.

2 is a side view of the state of use of the airway intubation aid according to the embodiment of the present invention.
3 to 6 are schematic diagrams for explaining the method of the present invention step by step.
FIG. 7 is a top view of a light pipe of a tracheal intubation assistance device according to an embodiment of the present invention. FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto. The basic contents of the present invention will be described with reference to Figs. 1 to 6 basically, and the remaining drawings will be referred to where necessary.

The airway intubation aid 1 of the present invention basically includes a light tunnel 10, a handle 20, a viewing window 30, and a wire rod 40.

A light through hole (11) through which light is emitted is provided in the form of a small hole in front of the optical tube (10) in the form of a casing having an upper light - tight conformation. A transparent window 30 is detachably attached to the rear of the optical tube 10 which is wider than the front side. That is, the object in front of the optical tube 10 can be enlarged and viewed through the transparent window 30.

A handle 20 in the form of a cylindrical case is integrally connected to one side of the optical tube 10. The handle 20 is provided with a space for mounting one or more small batteries. A lamp (not shown) that is turned on by the power of the battery installed in the handle 20 is installed inside the optical tube 10 or inside the handle 20. [ On the side of the handle 20, a switch 21 is provided for turning on and off the lamp. The switch 21 can be selected in various manners such as a pushing type, a dialing type, a lever type, and the like.

Although not shown, a mirror (not shown) for guiding the path of the light emitted from the lamp to the light through hole 11 in front of the optical tube 10 is installed in the optical tube 10. If the mirror is installed obliquely at an angle of 45 ° with respect to the longitudinal direction of the optical tube 10, the light path can be converted into a 90 ° angle. The viewing window 30 can be inserted or removed in a sliding manner through the rails 12 and 13 provided on both sides of the rear side of the optical tube 10. The viewing window 30 may be a magnifying glass and may further be made of a transparent synthetic resin.

The configuration described above can be said to be a composition that is widely used in ophthalmology, otorhinolaryngology, or pediatric hospitals to closely examine the affected part, that is, an arrangement equivalent to a gum. Therefore, a more detailed description thereof will be omitted.

According to an aspect of the present invention, an insertion hole (31) is formed in the viewing window (30). The insertion hole 31 may have a diameter of 0.5 to 2 mm, and the narrow wire 40 can be inserted therein.

The insertion hole 31 is provided at a position shifted to one side from the center of the viewing window 30 as shown in Fig. And may be provided at a position shifted rightward or downward to the user's convenience.

The wire rod 40 having a diameter that can be inserted into the airway of the small animal M can be inserted through the insertion hole 31. [ Any material can be used if the wire material 40 is a rigid material such as a wire. Therefore, various metals such as iron, stainless steel, copper or aluminum, or synthetic resin (fibers) such as nylon, PVC or glass fiber can be used .

The wire rod 40 may have a diameter of 0.5 to 1.5 mm and a length of 100 to 150 mm, which is easy to handle. The wire rod 40 can protrude from the front of the optical tube 10, that is, through the light through hole 11. [ It is preferable that the diameter of the light through hole 11 is not too narrow as compared with the wire rod 40. [ It is preferable to allow the object located in front of the wire member 40 to be identified through the light through hole 11 even after the wire member 40 is inserted. Therefore, it is preferable that the hole diameter of the light through hole 11 be about 2 to 5 times as large as the diameter of the wire rod 40. [

Hereinafter, the method of intubating the airway of a small animal (M) such as a laboratory mouse using the above-described airway intubating aid (1) will be described step by step with reference to FIG. 2 to FIG.

The wire rod 40 is inserted into the insertion hole 30 of the window 30 and the wire rod 40 is projected from the light through hole 11 as shown in FIG. Thereafter, it is confirmed by using the sight window 31 and the light L that the airway of the small animal M is opened, and the wire rod 40 is inserted into the small animal airway at the moment when the airway is opened 2).

Then, the airway intubation assistance instrument 1 is pulled out with the wire rod 40 sandwiched therebetween. Then, the administration tube 50 is inserted into the outside of the wire rod 40, and the administration tube 50 is inserted into the airway interior Steps, Figs. 3 and 4). That is, the delivery tube 50 is inserted into the airway by using the wire rod 40 as a guiding means.

Then, the wire rod 40 inserted in the airway is withdrawn from the administration tube 50 (third step, see FIG. 5). This completes the process of intubating the administration tube 50 into the air of the small animal (M). Then, by connecting the drug supply device 60 supplying the medicament such as the inhalation anesthetic to the end portion 51 of the administration tube, it becomes possible to administer the inhalation anesthetic or the like (see FIG. 6).

The above description is only an example based on the technical idea of the present invention. Those skilled in the art will recognize that various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. For example, all embodiments described above may be freely combined and practiced by those skilled in the art, and any combination thereof should be construed as being included within the scope of the present invention.
