Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an oral probe.

[Conventional technology]

Conventionally, oral probes used for administering various samples such as feed and drugs to small animals, such as mice, rats, hamsters, and guinea pigs, have a spout 33 connected to an inlet tube 11, as shown in FIG. It was shaped with a straight opening at the tip.

[Problem that the invention attempts to solve]

However, when using such conventional oral probes, since there is an opening at the tip of the introduction tube, when inserting the oral probe, the esophagus or stomach is often injured, or the mucous membrane is pierced. In addition, there was a defect in that the opening was likely to be tightly closed by the mucous membrane of the stomach, which hindered the sample pouring operation.

[Means for solving problems]

Therefore, the inventor of the present invention has devised the present invention as a result of intensive studies to eliminate such drawbacks of the conventional technology.

That is, the present invention is an oral sonde characterized by having a rounded tip and an introduction tube with a pore for dispensing formed in the side wall of the tip.

〔Example〕

The present invention will be further explained below with reference to the drawings showing one embodiment.

Reference numeral 1 denotes an introduction tube, and a rounded body 2 is formed at the tip thereof. The specific shape of the rounded body 2 may be any shape as long as it is easy to insert and does not cause damage to the esophagus or stomach, but a spherical shape is particularly effective. Also,
A specific method for forming the rounded body 2 is a method in which the tip of the introduction tube 1 is heated and melted and integrally formed.
It does not matter how you attach it to the tip of the introduction tube 1 by screwing, welding, etc., but it is best to attach it detachably by screwing.
This is advantageous because it facilitates cleaning by disassembly.

Reference numeral 3 denotes a pouring pore, which is located on the side wall of the tip of the introduction tube 1, in other words, the introduction tube 1 at a slightly upper portion of the rounded body 2.
It is formed on the side wall. Although one pore portion 3 is usually sufficient, a plurality of pore portions 3 may be provided in consideration of the pore diameter as appropriate.

In addition, when forming the pore 3, it is best to form it at a position closer to the rounded body so that no space is formed in the introduction pipe between the rounded body and the cleaning etc. preferred for operations.

Reference numeral 4 denotes a syringe attachment and fixing part such as a syringe barrel, which is formed at the base end of the introduction tube 1 so as to face the rounded body 2.

[Function] As described above, in the oral sonde of the present invention, the tip of the introduction tube 1 is rounded, and the pouring pore 3 is formed in the side wall instead of the tip of the introduction tube.
There is no obstruction to the insertion operation due to the conventional spouting opening, especially its edge, and a smooth insertion action can be obtained, and the clogging of the spouting pore 3 by the gastric mucosa is avoided, and the sample This enables reliable dispensing.

[Effect of idea]

Accordingly, by using the oral probe of the present invention, various samples can be safely, easily and reliably injected into the animal body without damaging the esophagus or stomach.
