Abstract
The utility model relates to a PH value detection device of gastric juice and belongs to the field of medical devices. The PH value detection device of gastric juice is provided with a valve body which adopts a three-way valve type structure; the middle opening of the valve body is a cone type plug hole in which a cone type valve plug is installed; the valve plug is located with a locating slot on the plug hole through a locating key; a groove is processed on the valve plug; the groove is communicated with a fluid outlet hole at the top part of the valve plug; and a one-way valve is installed on the fluid outlet hole. The PH value detection device of gastric juice has simple structure and easy operation, and can directly measure the PH value of gastric juice with high accuracy.
Description
Technical field
This utility model relates to medical instruments field, at length says it is a kind of gastric juice pH value checkout gear.
Background technology
As everyone knows, patients with gastric disease need often carry out the gastric juice pH value and detect, and a kind of method is that pipette is stretched into gastral cavity from the gastroscope keyhole, draws gastric juice with syringe, but its complicated operation, and the patient suffering is big; Another kind method is, chemical reagent is added in the negative pressure bottle, produces chemical reaction with gastric juice, and according to the acidity of reagent paper change in color estimation gastric juice, this method accuracy is not high, can not directly measure the pH value of gastric juice, complex structure, and not easy to operate.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of gastric juice pH value checkout gear, and is simple in structure, and easy operating can directly be measured the pH value of gastric juice and accuracy height.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of gastric juice pH value checkout gear, be provided with valve body, valve body adopts three-way valve formula structure, the intermediate openings of valve body is the circular cone type consent, the circular cone type valve plug is installed in the consent, and the locating slot location of valve plug on positioning key and consent is processed with groove on the valve plug, groove is connected with the liquid outlet at valve plug top, and check valve is installed on the liquid outlet.
The beneficial effects of the utility model are, and are simple in structure, and easy operating can directly be measured the pH value of gastric juice and accuracy height.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1, structural representation of the present utility model.
1. valve bodies among the figure, 2. valve plug, 3. valve top, 4. liquid outlet, 5. locating slot, 6. positioning key, 7.PH value reagent paper, 8. groove, 9. clear opening, 10. taper joint, 11. consents.
The specific embodiment
In Fig. 1, this utility model is provided with valve body 1, valve body 1 adopts three-way valve formula structure, valve body 1 is a clear opening 9 laterally, clear opening 9 two ends are separately installed with a staged taper joint 10, the intermediate openings of valve body 1 is a circular cone type consent 11, and circular cone type valve plug 2 is installed in the consent 11, and valve plug 2 is located through positioning key 6 and the locating slot 5 on the consent 11, be processed with groove 8 on the valve plug 2, be provided with pH value reagent paper 7 in the groove 8, valve plug 2 tops are valve top 3, are processed with liquid outlet 4 on the valve top 3, groove 8 is connected with liquid outlet 4, on the liquid outlet 4 check valve is installed, the effect of check valve is that liquid can only enter liquid outlet 4 from groove 8, and stops air to enter groove 8 through liquid outlet 4.
This utility model is in the time need detecting patient's gastric juice, the staged taper joint 10 at valve body 1 two ends is installed between gastroscope and the negative pressure bottle, rotation valve plug 2, then gastric juice flows to liquid outlet 4 through groove 8, and contact with pH value reagent paper 7 in the groove 8, pH value reagent paper 7 and gastric juice generation chemical reaction and variable color, thus can demonstrate the pH value of gastric juice directly and accurately.
Claims (1)
1, a kind of gastric juice pH value checkout gear, be provided with valve body, it is characterized in that: valve body adopts three-way valve formula structure, the intermediate openings of valve body is the circular cone type consent, the circular cone type valve plug is installed in the consent, and the locating slot location of valve plug on positioning key and consent is processed with groove on the valve plug, groove is connected with the liquid outlet at valve plug top, and check valve is installed on the liquid outlet.
