Abstract
The utility model discloses a disposable anti-reflux indwelling gastric tube, which comprises a tube body with a through hole arranged in the front end, wherein more than one one-way valve is arranged in the tube body, and the one-way valve is arranged on the centre line of the tube body. The disposable anti-reflux indwelling gastric tube has the advantages of reasonable design, simple structure, and convenience for use; foods in the stomach smoothly flows into the stomach, meanwhile the backflow of the foods remained in the stomach can be avoided, the discomfort of the patient is reduced, the accuracy and effectiveness of the nursing service are improved, the complication is reduced, and the safety of the patients is protected.
Description
Technical field
This utility model relates to the medical device technical field, is specifically related to a kind of disposable anti-adverse current indwelling gastric tube.
Background technology
Because the critical patient of stupor that a variety of causes causes or generation dysphagia can not independently swallow, clinical middle patient need rely on nasal feeding tube feed water that human body energy is provided, so the nasal feeding diet is a general and very important clinically nursery work.The nasal feeding diet nursing is directly determining the picked-up of patient's body water and nutrient substance, also is to keep the body electrolyte balance, promotes the necessary means of patient's rehabilitation.
When carrying out nasal feeding for patient, the coma patient central nervous system changes the reactivity that makes the trachea sensitive part and reduces, and food is removed dysfunction, and gastric emptying prolongs; The factor that foreign body such as indwelling gastric tube stimulates in cavum nasopharyngeum and the esophagus in addition is easy to take place food backflow; Secondly since stomach tube to put the pipe degree of depth long; Annotate in the tube chamber of food back and be prone to food residual or liquid, be prone to residue in gastric content and the tube chamber and backflow, especially for the patient of tracheotomy through indwelling gastric tube is reverse; Food often occurs through the phenomenon that stomach tube backflows; Thereby, increased the chance of patient's pulmonary infection, even the patient is suffocated.
In addition, the position because of the patient during nasal feeding is improper, or the nursing staff operate lack of standardization, or the liquid temperature food phenomenon of backflowing that all can occur such as improper.The employed stomach tube of present clinical nasal feeding can't make the problems referred to above effectively solved.
The utility model content
The purpose of this utility model is the deficiency that exists to prior art, and a kind of disposable anti-adverse current indwelling gastric tube simple in structure and easy to use is provided.This disposable anti-adverse current indwelling gastric tube not only can make the food in the stomach tube flow into gastric smoothly, can prevent backflowing of the interior residue of stomach tube simultaneously again.
For realizing above-mentioned purpose; The technical scheme that this utility model adopts is: disposable anti-adverse current indwelling gastric tube; Comprise that front end is provided with the body of through hole, is characterized in that: be provided with an one-way cock in the said body at least, said one-way cock is positioned on the centrage of body.
Above-mentioned disposable anti-adverse current indwelling gastric tube; It is characterized in that: said one-way cock comprises a trumpet-shaped valve body of being processed by elastomeric material; The rear end of valve body is provided with the bore back valve port identical with internal diameter of tube body; The front end of valve body is provided with the preceding valve port of bore less than back valve port bore, and the edge of said back valve port is connected with the inwall of said body.
This utility model compared with prior art has the following advantages:
(1) this utility model is reasonable in design, and is simple in structure, easy to use;
(2) not only can make the food in the stomach tube flow into gastric smoothly, can prevent backflowing of the interior residue of stomach tube simultaneously again, alleviate subject discomfort, improve the accurate and effectiveness of nursery work, reduce the generation of complication, protect patient's safety.
Through accompanying drawing and embodiment, the technical scheme of this utility model is done further detailed description below.

Fig. 2 is the structural representation of this utility model one-way cock.
Description of reference numerals:
The 1-through hole; The 2-body; The 3-one-way cock;
The 4-valve body; Valve port before the 5-; Valve port behind the 6-.
The specific embodiment
As shown in Figure 1, this utility model comprises that front end is provided with the body 2 of through hole 1, is provided with an one-way cock 3 in the said body 2 at least, and said one-way cock 3 is positioned on the centrage of body 2.
As shown in Figure 2; Said one-way cock 3 comprises a trumpet-shaped valve body 4 of being processed by elastomeric material; The rear end of valve body 4 is provided with the bore back valve port 6 identical with body 2 internal diameters; The front end of valve body 4 is provided with the preceding valve port 5 of bore less than back valve port 6 bores, and the edge of said back valve port 6 is connected with the inwall of said body 2.
The body 2 of this utility model stomach tube and the valve body of one-way cock 34 are processed by silica gel material.One-way cock 3 vertically is arranged in the tube chamber of stomach tube and is positioned on the centrage of body 2, and preceding valve port 5 is towards the front end of stomach tube body 2.When using this stomach tube to carry out the nasal feeding operation; At first connect the notes feeder of suitable model in the rear end of body 2; Steadily feeder is annotated in pushing then, and food promptly flows forward along the inner chamber of body 2, when the food side of arrival one-way cock 3; Food is easy to get into valve body 4 by the big back valve port 6 of bore under the promotion of pressure, and gets into patient's gastric through preceding valve port 5.When anti-stream takes place in food in being trapped in stomach tube, the food in the body 2 by forward direction after reverse flow, when food flow to one-way cock 3; Valve port 5 before at first arriving, because of the bore of preceding valve port 5 is little, food be difficult to through; The food in valve port 5 outsides is pressed on the trumpet-shaped valve body 4 before being trapped in, and makes the valve body of being processed by elastomeric material 4 produce distortion, with the distortion of valve body 4; The bore of preceding valve port 5 diminishes; To the last close, make the food of adverse current can not pass through one-way cock 3, thereby prevented the generation of food adverse current.
