Abstract
The utility model relates to an injector for a stomach tube, which comprises a needle cylinder, a piston positioned inside the needle cylinder and a push rod connected with the piston, wherein a piece of pH (Potential Of Hydrogen) test paper is fixed on the inner wall of the needle cylinder. According to the injector for the stomach tube, the pH test paper is fixed on the inner wall of the needle cylinder of the injector; after the stomach tube is placed in a patient body, direct suction is performed; after a sucked content gets into the injector and is contacted with the pH test paper, the alkalinity or acidity of the content can be directly distinguished outside the injector; and if the content is acidic, the stomach tube is in the stomach, so that whether the stomach tube is in the stomach of a patient is correctly judged; through adopting the injector provided by the utility model, the detection is fast and efficient; the detection time is greatly shortened; the operation is simple and convenient; and the manufacturing cost is low.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of stomach tube syringe.
Background technology
Check whether stomach tube has three kinds of methods usually at patient's gastric after inserting stomach tube: (1) injects air in stomach tube, listen stomach to have or not gur gling with stethoscope simultaneously, if any proving that then stomach tube is at gastric, but injecting air to gastric can cause the patient uncomfortable, if stomach tube in air flue, then can cause the air flue damage; (2) patient is external stomach tube end places water, then point out stomach tube to be strayed into air flue if any bubble, but this method is in case of emergency inapplicable; (3) extract the stomach tube content, if can extract gastric juice or food out then point out stomach tube at gastric, this method is more suitable.But also there is shortcoming in the third method, also can extract food out if stomach tube is tortuous in esophagus, if extraction is liquid, with the naked eye can't accurately judge whether it is gastric juice.
Because it is acid that gastric juice is, but go out from the Acidity of Aikalinity of the liquid of stomach tube extraction with pH reagent paper fast detecting, but before with the pH detection paper, taking out the syringe of gastric juice need pull up from stomach tube, may cause gastric juice or the food medicated clothing of making dirty, and get content again after syringe pulled up, and increased detection time, brought more pain sensation to the patient.
The utility model content
The purpose of this utility model is at deficiency of the prior art, and a kind of stomach tube syringe is provided.
For achieving the above object, the technical scheme taked of this utility model is:
A kind of stomach tube syringe comprises syringe, is positioned at the piston and the push rod that is connected described piston of described syringe inside, and the pH reagent paper is fixedly arranged on the inwall of described syringe.
Described pH reagent paper is square, rectangle, circle or triangle.
Described syringe inwall is provided with groove, and described pH reagent paper is fixed in the groove.
This utility model advantage is: this stomach tube with syringe by the pH reagent paper being fixed in the inwall of injector syringe, treat directly to aspirate after stomach tube is inserted in patient's body, after the content that extracts enters syringe and contacts the pH reagent paper, just can directly differentiate the Acidity of Aikalinity of content from syringe exterior, as be acidity and stomach tube then be described at gastric, thereby judge that accurately whether stomach tube is at patient's gastric; Use this utility model syringe to detect fast effectively, shortened detection time greatly, and easy and simple to handle, cost of manufacture is low.
Description of drawings
Accompanying drawing 1 is the structural representation that this utility model stomach tube is used syringe.
Accompanying drawing 2 is that this utility model stomach tube uses syringe along the cross-sectional view of long axis direction.
The Reference numeral and the ingredient that relate in the accompanying drawing are as follows:
1. syringe 11. grooves
2. push rod 3. pistons
4.pH reagent paper
The specific embodiment
Below in conjunction with embodiment and with reference to accompanying drawing this utility model is further described.
Please refer to Fig. 1, Fig. 1 is the structural representation that this utility model stomach tube is used syringe.This stomach tube comprises syringe 1, is positioned at the piston 3 and the push rod 2 that is connected described piston 3 of described syringe 1 inside with syringe, and pH reagent paper 4 is fixedly arranged on the inwall of described syringe 1.Inwall at syringe 1 is provided with groove 11, asks for an interview Fig. 2, and Fig. 2 is that this utility model stomach tube uses syringe along the cross-sectional view of long axis direction, and the shape of groove 11 is consistent with the shape of pH reagent paper 4, the consistency of thickness of the degree of depth of groove 11 and pH reagent paper 4.PH reagent paper 4 is fixed in the groove 11, and pulling is during push rod 2, and piston 3 can not be taken away or mobile pH reagent paper 4, and after the content that extracts enters syringe 1, and pH reagent paper 4 can be not floating or be buried in content convenient color of observing pH reagent paper 4.In the present embodiment, pH reagent paper 4 is rectangle, and the shape of groove 11 is the same with pH reagent paper 4.
Need to prove that described pH reagent paper 4 can also be square, circle, triangle or other shape, the shape of the shape of groove 11 and pH reagent paper 4 is consistent.
This utility model stomach tube also can not arrange groove 11 with the syringe 1 of syringe, pH reagent paper 4 directly is fixed on the inner wall surface of syringe 1, in this kind design, the initial position of piston 3 is positioned at the top of pH reagent paper 4, described top refers to when modes of emplacement employing Fig. 1 of syringe or the plumbness among Fig. 2, when pulling push rod 2, piston 3 can not run into pH reagent paper 4.
This stomach tube with syringe by pH reagent paper 4 being fixed in the inwall of injector syringe 1, treat directly to aspirate after stomach tube is inserted in patient's body, after the content that extracts enters syringe and contacts pH reagent paper 4, just can directly differentiate the Acidity of Aikalinity of content from syringe exterior, as be acidity and stomach tube then be described at gastric, thereby judge that accurately whether stomach tube is at patient's gastric; Use this utility model syringe to detect fast effectively, shortened detection time greatly, and easy and simple to handle, cost of manufacture is low.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
Claims (3)
1. stomach tube syringe comprises syringe, is positioned at the piston and the push rod that is connected described piston of described syringe inside, it is characterized in that the pH reagent paper is fixedly arranged on the inwall of described syringe.
