Abstract
The utility model discloses a nasal feeding tube which comprises a tube body (1) with an open upper end and a closed bottom end. One or more liquid outlet holes (3) are formed in the side wall of the lower end of the tube body (1). A downward one-way valve piece (5) is arranged on the inner wall of the upper end of the tube body (1). An integral needle base (2) is arranged at the top end of the tube body (1). An injection through hole (4) is arranged in the needle base (2). The injection through hole (4) is communicated with an inner cavity of the tube body (1). The inner wall of the injection through hole (4) is fitted with the outer wall of a syringe nipple. Length scale marks (6) are arranged on the outer wall of the tube body (1). The nasal feeding tube can prevent stomach contents from flowing back and nutrition liquid from leaking during injection, facilitates reading of the length of the tube body inserted into a human body, and is convenient to use.
Description
Technical field
This utility model relates to a kind of nasal feeding tube, belongs to technical field of medical instruments.
Background technology
At present, the clinical nasal feeding tube of using is General Purpose Rubber flexible pipe or silica gel tube, the end sealing of pipe, and the other end opening of pipe, the sidewall that closes on the blind end pipe is provided with liquid outlet.During use syringe nipple is inserted the nasal feeding tube opening, the liquid nutritional thing pushes nasal feeding tube by syringe, is entered in the stomach by the liquid outlet above the sidewall of nasal feeding tube lower end again.Because the diameter of existing nasal feeding tube top end opening will pinch nasal feeding tube and syringe nipple junction greater than the diameter of syringe nipple with hands during use, prevent that liquid from leaking from the junction between syringe nipple outer wall and the nasal feeding tube inwall, use inconvenient.After nasal feeding is complete, for avoiding the gastric content adverse current, must will bind up with gauze behind the nasal feeding tube opening opisthotonos, to clamp with clip again or tie with cotton rope, this method troublesome poeration is wasted time and energy, and easily cross infection is occured.
Summary of the invention
This utility model provides a kind of can prevent the food adverse current, nasal feeding tube easy to use.
This utility model technical solution is: a kind of nasal feeding tube, comprise the body that upper end open and bottom are sealed, and the lower end sidewall of body is provided with the liquid outlet more than 1 or 1, and inboard wall of tube body is provided with downward check valve sheet in the upper end of body.
As improvement, the top of body is provided with the needle stand of one, and needle stand is provided with the injection through hole, and the injection through hole communicates with the inner chamber of body, and the inwall of injection through hole and the outer wall of syringe nipple are suitable.
As improvement, the outer wall of body is provided with the length graduation mark.
Technique effect of the present utility model is: this utility model is provided with downward check valve sheet at the upper end of body inboard wall of tube body, and this check valve sheet effect is that liquid can only pass through downwards, and liquid oppositely by cut-off, has been avoided the gastric content adverse current.Needle stand is provided with the injection through hole on the top of this utility model body, the inwall of injection through hole and the outer wall of syringe nipple are suitable, because the outer wall of syringe nipple is the conical surface, good airproof performance, as long as being seated in syringe nipple in the injection through hole is the injectable nutrient liquid, can avoids leak of liquid during injection.The outer wall of body is provided with the length graduation mark, can conveniently read the length that body inserts human body, and is easy to use.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is this utility model top view.
The specific embodiment
Describe in detail below in conjunction with drawings and Examples:
As shown in Figure 1 to Figure 3, a kind of nasal feeding tube of this utility model comprises the body 1 that upper end open and bottom are sealed, and the lower end sidewall of body 1 is provided with the liquid outlet 3 more than 1 or 1, and present embodiment adopts 2 liquid outlets, and 2 liquid outlets are arranged above and below.Be provided with downward check valve sheet 5 at the upper end of body 1 inboard wall of tube body.The top of body 1 is provided with the needle stand 2 of one, and needle stand 2 is provided with injection through hole 4, and injection through hole 4 communicates with the inner chamber of body 1, and the inwall of injection through hole 4 and the outer wall of syringe nipple are suitable.The outer wall of body 1 is provided with length graduation mark 6.Present embodiment nasal feeding tube material adopts rubber or silica gel.
During use, this utility model body 1 is inserted stomach by conventional method, the length that body 1 inserts reads according to length graduation mark 6, being seated in syringe nipple in the injection through hole is the injectable nutrient liquid, inject complete, syringe nipple is extracted and get final product from the injection through hole, owing to being provided with downward check valve sheet 5 at the upper end of body 1 inboard wall of tube body, can avoid the gastric content adverse current.
The unspecified content of this utility model is prior art; under the prerequisite that does not break away from this utility model design concept; various distortion and improvement that those skilled in the art make the technical solution of the utility model all should be included in the rights protection scope of the present utility model.
