Fig. 2 is a perspective cross-sectional view showing an embodiment of the present invention.

Figure 3 is a plan sectional view showing an embodiment of the present invention.

The above and other objects, features and advantages of the present invention will become more <RTIgt; In a first embodiment of the feeding tube of the present invention, the feeding tube comprises a catheter 1 and a set of connectors 2, the catheter 1 being coupled to the socket 2.

The catheter 1 can be inserted into the stomach through the throat of the animal and along the esophagus so that a fluid can be directly infused into the stomach of the animal by the catheter 1. The catheter 1 is made of a material having elastic bending. The material of the catheter 1 is preferably a plastic material, so that the texture of the catheter 1 can be both hardness and elasticity, and the catheter 1 is not in the process of feeding the animal. It is difficult to extend into the animal's gastroesophage due to insufficient hardness, or even cause blockage, which ensures the stability and smoothness of the infusion operation. In addition, if the angle of the catheter 1 is not correct, the catheter 1 can also be bent along the structure of the gastroesophage to reduce the damage or puncture of the animal's throat, esophagus or stomach. In the embodiment, the plastic material is preferably polypropylene. The polypropylene has the characteristics of high hardness, bending resistance, easy processing, and low price, thereby achieving the effects of increasing durability and reducing production cost.

The catheter 1 further has a sleeve 11 which is fitted over the outside of the catheter 1 to provide a protective layer and cushioning effect of the catheter 1. The inner diameter of the sleeve 11 is preferably slightly smaller than the outer diameter of the catheter 1, whereby the sleeve 11 can be brought closer to the effect of the catheter 1. The sleeve 11 is made of a material that is softer than the tube 1. The material of the sleeve 11 is, for example but not limited to, a rubber material. The sleeve is made of rubber with better softness than the plastic. 11 can cooperate with the catheter 1 to extend into the body cavity of the animal, and buffer the contact and friction between the catheter 1 and the inner wall of the body cavity, thereby achieving the effect of slowing the stimulation of the animal. In this embodiment, the material of the sleeve 11 is preferably a silicone material. The silicone rubber has better biocompatibility than the rubber, and is often used as a medical plastic filling or a wound dressing. Therefore, the rubber is used as the sleeve. The material of 11 can achieve the effect of slowing down the stimulation of animals. The length of the sleeve 11 is less than the length of the conduit 1 such that the conduit 1 has at least one end that is not covered by the sleeve 11 and can be joined to the socket 2 by means of the end.

The socket 2 has a first engaging hole 21 and a second engaging hole 22, and the first engaging hole 21 and the second engaging hole 22 communicate with each other. The first engaging hole 21 is sleeved with one end of the catheter 1. In the embodiment, the inner diameter of the first engaging hole 21 is preferably slightly smaller than the outer diameter of the catheter 1 , thereby the catheter 1 and the catheter 1 can be The first engagement hole 21 can achieve a tighter fit. In addition, after the catheter 1 is inserted into the first engaging hole 21 and fixed, an adhesive material 23 is preferably applied to the end edge of the first engaging hole 22, and the catheter 1 is coated at the same time, thereby achieving reinforcement. The catheter 1 and the socket 2 are combined to fix the effect. The second engaging hole 22 can be fitted to the outlet end of a syringe A. In this embodiment, the end edge of the second engaging hole 22 can further extend radially outwardly from a wing 24 when the second joint is used. When the hole 22 is fitted to the outlet end of the syringe A, the sleeve 2 can be more tightly coupled to the syringe A by pressing against the flap 24 in the direction of the syringe A. On the contrary, the flap 24 can also be biased in the opposite direction for the force applying point, so that the sleeve 2 is removed from the syringe A, thereby improving the efficiency and convenience of installation and removal.

The other end of the catheter 1 is preferably coupled to a buffer member 3 having a through hole 31 and a blunt edge 32. The through hole 31 penetrates the buffer member 3 from the center of the blunt edge 32, and the through hole 31 sets are fitted to the catheter 1. During the feeding of the animal, the cushioning member 3 can buffer when the other end edge of the catheter 1 contacts the inner wall of the body cavity, and causes the catheter 1 to slide along the inner wall of the body cavity, thereby changing the penetration of the catheter 1. Angle, by which the effect of slowing down animal damage can be achieved. In this embodiment, the inner diameter of the through hole 31 is preferably slightly smaller than the outer diameter of the catheter 1, thereby enabling the catheter 1 and the cushioning member 3 to achieve a tighter fit. The material of the buffering member 3 is not limited, and may be a material such as rubber or silicone. In the embodiment, the cushioning member 3 is preferably made of a rubber material, because the rubber has better hardness than the silicone rubber, and has a better hardness than the plastic. The softness is preferred, so that the cushioning member 3 can be easily deformed and detached after being coupled to the catheter 1, and can maintain moderate elasticity.

Referring to Fig. 3, according to the above structure, the catheter 1 can extend into the throat, esophagus, and stomach of the animal, and is bent along with the structure of each part to achieve the effect of slowing the damage of the animal. The sleeve 11 can provide a protective layer and a buffering function of the catheter 1 and cooperate with the catheter 1 to extend into the body cavity of the animal, thereby slowing the contact and friction between the catheter 1 and the inner wall of the body cavity, thereby slowing the stimulation of the animal. effect. The catheter 1 is coupled to the first engagement hole 21 of the socket 2 and can be further fitted to the outlet end of the syringe A by the second engagement hole 22. The cushioning member 3 can generate a cushioning effect when the end edge of the catheter 1 comes into contact with the inner wall of the body cavity, and causes the catheter 1 to change the angle of penetration, thereby achieving an effect of improving the damage of the animal.

In summary, the feeding tube of the present invention can be installed in a syringe and protrudes into the stomach through the throat and esophagus of the animal, directly injecting liquid food or medicine into the stomach, and can follow the structure in the body cavity. Bending to reduce the damage of the animal's throat, esophagus and stomach. In addition, the sleeve can buffer the contact and friction of the catheter with the inner wall of the body cavity, thereby achieving the effect of slowing the stimulation of the animal.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
