Abstract

The utility model discloses an esophageal dilator, comprising a hard main tube; the outer surface of the main tube is sheathed with an air sac which is fixedly connected with the outer wall of the main tube and communicated with an air pipe, the other end of the air pipe is connected with an inflation ball, and the air sac takes a ladder shape and becomes increasingly broad from top to bottom. Repeated intubation can be avoided, which can alleviate pains of patients and is not likely to cause damage to the esophageal mucous membrane; the esophageal dilator can substitute a gastric tube for feeding patients.

Description

Esophageal dilator

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to the esophageal dilator that uses for the esophageal stricture patient.

Background technology

At present, the esophageal stricture patient who causes for a variety of causes will carry out the esophagectasia treatment, general Therapeutic Method is: use the hardmetal pipe to insert esophagus, begin to expand to gradually large size from trumpet, all will intert again at every turn, intubate is difficulty relatively, cause very big misery to the patient, owing to be rigid expansion, make the esophageal mucosa membrane injury bleeding due to trauma easily, make it further narrow.

Summary of the invention

The purpose of this utility model is, in order to overcome the deficiencies in the prior art, and provides a kind of esophageal dilator, and this scheme intubate is easy, and is easy to use, little to the esophagus damage.

For solving the problems of the technologies described above, the technical solution of the utility model is: esophageal dilator, comprise the rigid person in charge, outside being responsible for, be set with air bag, air bag is fixedlyed connected with person in charge's outer wall, and air bag communicates with breather, and the other end of breather connects inflatable ball, described air bag is a stairstepping, from top to bottom chap gradually.After dilator inserts esophagus, give airbag aeration with inflatable ball by breather, caliber at the air bag position is increased, thereby make the narrow esophagectasia of corresponding site, because air bag is a stairstepping, diameter from fine to coarse, can make the thinnest being positioned in upper end need the esophagus place that expands earlier, in advance expansion, and then successively his air bag of thicker part is inserted, the even soft affected part that acts on of expansionary force like this, expansion along with air bag, the esophageal stricture position obtains expansion, and interspersed convergent divergent channel that need not be has repeatedly alleviated misery to the patient.

Described air bag is three stairsteppings.General three kinds of rugosity just can satisfy the requirement of treatment, and air bag is made simpler simultaneously.

Described person in charge top is a blind end, has a side opening at least in the side of blind end.Carrying out esophagus simultaneously, can send into water or liquid food by the person in charge, liquid can flow into gastric from side opening, has realized giving patient's feeding.

The beneficial effects of the utility model are: because the person in charge of esophageal dilator outside is set with air bag, air bag is fixedlyed connected with person in charge's outer wall, and air bag communicates with breather, and the other end of breather connects inflatable ball, described air bag is a stairstepping, from top to bottom chap gradually.Interspersed pipe that need not be has repeatedly alleviated patient's misery, is difficult for causing the damage of esophageal mucosa membrane injury, can replace stomach tube, gives patient's feeding.

Description of drawings

Fig. 1 is a sectional structure sketch map of the present utility model;

1-side opening among the figure, 2-is responsible for, 3-air bag, 4-breather, 5-inflatable ball.

The specific embodiment

According to shown in Figure 1, esophageal dilator, comprise the rigid person in charge 2, be set with air bag 3 in the person in charge 2 outsides, air bag 3 is fixedlyed connected with the person in charge's 2 outer walls, air bag 3 communicates with breather 4, the other end of breather 4 connects inflatable ball 5, and air bag 3 is three stairsteppings, from top to bottom chap gradually, being responsible for 2 tops is blind end, has a side opening 1 in the side of blind end.When air bag 3 expand into the rugosity value of a regulation, even internal pressure increases, the diameter of air bag also no longer increases, and can make air bag use different diameter parts period in the difference treatment.The other parts of not mentioning in this utility model are prior art, do not elaborate at this.

Claims

1, esophageal dilator, comprise the rigid person in charge (2), it is characterized in that: outside being responsible for (2), be set with air bag (3), air bag (3) is fixedlyed connected with the person in charge's (2) outer wall, air bag (3) communicates with breather (4), the other end of breather (4) connects inflatable ball (5), and described air bag (3) is a stairstepping, from top to bottom chap gradually.

2, esophageal dilator according to claim 1 is characterized in that: described air bag (3) is three stairsteppings.

3, esophageal dilator according to claim 1 and 2 is characterized in that: the described person in charge (2) top is a blind end, has a side opening (1) at least in the side of blind end.
