Description

A pH METER IN THE GASTROINTESTINAL}

The present invention relates to a pH (measured) concentration meter, and more particularly to a gastrointestinal pH meter that can immediately determine the pH of the gastrointestinal tract.

The US Heritage Dictionary defines 'pH' as a measure of acidity or alkalinity for years with a value of 7 for neutral solutions that increase with increasing alkalinity and acidity.

The range of use is from 0 to 14, in short, low pH solutions are very acidic, and the normal pH range of gastric acid is 1.5 to 3.5, with strong acidity.

This acidity is known to create an ideal environment for pepsin, a major digestive enzyme that breaks down food.

The pH of stomach acid is important for maintaining a healthy digestion.

Stomach acid is most effective for digestion at low pH, which makes it acidic. Incorrect pH and abnormal gastric acid can cause medical complications, including acid reflux, ulcers and gastritis (stomach inflammation).

Therefore, it is necessary to recognize the pH of the stomach and to maintain a healthy life accordingly accordingly.

Currently, the following methods are known to measure the pH of the stomach.

For example, X-ray examination of the esophagus, digestive system measurement, endoscopy or biopsy, etc., but all of these have a problem that it is cumbersome and time-consuming to measure the pH of the stomach using special equipment.

In addition, it is not easy to determine the pH because the pH should be measured using appropriate drugs and equipment.

First, the present invention is characterized in that it is possible to measure the hydrogen ion concentration (hereinafter referred to as pH) by using a simple device for gastric fluid inhaled from the stomach of a subject.

That is, the present invention is configured to measure the hydrogen ion concentration of the subject's stomach by using a pH meter 100 connected to one end of the tube 160 and the other end of the tube 160 which are put into the stomach of the subject.

To this end, the pH measuring device 100 has a space portion 115 therein, and a cylinder 110 having a connecting portion 150 connected to one end of the tube 160 in a stepped state is provided at the front side, and the cylinder 110 is provided. The crank 130 is moved forward and backward along the longitudinal direction of the cylinder in the space 111, and one end of the crank 130 is moved together in airtight contact with the inner wall of the cylinder 110 during forward and backward movement. While the piston 140 is coupled to provide a compressive force or to provide a suction force, the other end of the crank 130 is composed of a syringe formed with a handle (120).

In addition, on the outer wall of the cylinder 110, a volume indicator 113 indicating the volume of gastric fluid sucked into the cylinder is formed in scale.

And the inner wall of the cylinder is coupled to the piston 140 which is moved in the airtight contact state with the inner wall of the cylinder 110 as described above, the inner wall of the cylinder should not be attached to other possible attachments.

This is because the attachment cannot be dropped or maintained by the moving piston.

However, in the present invention, since the litmus paper is in contact with the gastric fluid sucked into the cylinder to measure the pH, the litmus paper 114 in the present invention should be installed on the inner wall which may come into contact with the gastric juice.

Therefore, the litmus paper 114 is cut to the minimum length that can detect the pH from gastric juice and should be attached to the inner wall of the cylinder as close as possible to the connection portion 150 of the pH meter 100.

FIG. 2 is a cross-sectional view taken along a direction A-A in FIG. 1.

1 and 2, the litmus paper 114 is thinly bonded to one side of the inner wall of the cylinder as close as possible to the space 111 formed by the inner wall of the cylinder, that is, the connecting portion 150, and to one side of the outer wall of the cylinder. pH reference table 112 and the capacity indicator 113 is formed or attached.

pH reference table 112 refers to a pH Color Chart, which is distinguished by the pH reference color to determine whether the aqueous solution is acidic, basic or neutral, and the volume indicator 113 is an aqueous solution (gastric fluid inhaled into the syringe) Are denoted cc to indicate the volume.

The dose display unit 113 may form a tick mark on the outer wall of the cylinder like an ordinary syringe, or may attach a simple eye tag.

In particular, since the conventional syringe can be used as it is except for the pH reference table 112 and litmus paper 114 in the present invention, litmus paper 114 should be attached to the inner wall of the cylinder 110, pH reference table 112 is Of course, it can be produced in various shapes.

That is, in the drawings of the present invention, although the entire pH Color Chart is illustrated and described as having a printed paper attached thereto, the present invention is not limited thereto, and in view of the fact that gastric juice is acidic, only a red-based color is displayed, or the pH color chart on a syringe wrapper. You can also print the whole thing.

Referring to Figure 3, an example of measuring the pH of the stomach with a pH meter 100 of the present invention is illustrated.

First, one end of the tube 160 of the present invention is inserted down the esophagus through the nose or mouth 310 of the subject 300 to be in contact with the bottom of the stomach 320.

Preferably, one end of the tube 160 should be positioned in the gastric fluid 330 so that gastric fluid can flow out well through the tube 160.

When one end of the tube 160 is fixed to the stomach 320, the other end of the tube 160 is connected to the connection portion 150 of the pH meter 100, and hold the handle 120 of the pH meter 100 to hold the piston Pulling 140 allows gastric fluid to be absorbed through one end of the tube 160 by suction force.

The examiner pulls the handle 120 slowly while watching the dose indicator 113 so that the gastric fluid flows into the space 111 of the cylinder 110 by the required dose.

In the present invention, the amount of gastric juice can be adjusted while looking at the dose display unit 113. Preferably, the amount of gastric juice is sucked only by the amount that the limousine paper 114 can contain so as to prevent unnecessary leakage of gastric juice.

Therefore, as described above, the litmus paper 114 should be cut to the minimum length capable of detecting pH from gastric juice and attached to the inner wall of the cylinder as close as possible to the connection part 150 of the pH meter 100.

Referring to FIG. 1, when extracting gastric fluid from an actual subject, the pH meter is gripped as shown in the drawing so that the pH reference table 112 displayed on the outer wall of the cylinder has a capacity indicator 113 at the top and litmus paper at the bottom. The 114 is positioned so that a change can occur in the litmus paper 114 as soon as any gastric fluid is introduced.

Of course, the pH reference table 112 and the capacity display unit 113 may be changed in position as necessary, but in the drawings-pH reference table 112, the capacity display unit 113 and litmus paper 114 are sequentially attached. The litmus paper 114 is directed downward to absorb the gastric juice, and to determine the pH while viewing the conversion color of the litmus paper 114, the pH reference table is adjacent to the litmus paper 114 adjacent to the litmus paper 114. Naturally, it is easy to distinguish the colors when 112 is located.

Referring to the reference drawing for explaining a method of determining the acidity of litmus paper changed in the detected gastric fluid of FIG. 4, there is a capacity indicator 113 on the litmus paper 114, but there is a pH reference table 112 at the top thereof. By comparing the results, it can be seen that pH can be measured at a glance.

According to the embodiment of the present invention described above, the litmus paper 114 may be installed on the inner wall of the cylinder to be easily damaged or dropped by the reciprocating motion of the piston 140 to prevent measurement.
