Description
Technical field
This utility model belongs to field of medical equipment technology, particularly relates to a kind of gastroscope spray line.
Background technology
Gastroscopy can observe directly the truth at examined position, more by carrying out pathological biopsy and cytolgical examination to suspicious lesions position, further to define diagnosis, is the first-selected inspection method of Lesions in Upper Gastrointestinal Tract.It stretches in stomach by very thin, a soft pipe, and doctor directly can observe esophagus, the duodenal pathological changes of harmonization of the stomach, especially to small pathological changes.If do not need the disease that pathological findings just can be clarified a diagnosis in gastroscopy, directly spraying medicine treatment can be carried out.But existing gastroscope spray line does not possess the function preventing gastric content adverse current, if intragastric pressure is large after spray medicine, gastric content (comprising gastric juice and medicine) can be up along spray line, and not only polluting spray line also affects the drug effect of again spraying medicine and play a role.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of gastroscope spray line that can prevent gastric juice adverse current.
The purpose of this utility model is achieved through the following technical solutions.
A kind of gastroscope spray line, comprise body and spray tube head, the tube wall of described sprinkling tube head is provided with some insecticide-spraying holes, the inwall of described body bottom is the prismatoid of runner in the middle of inwardly giving prominence to and being formed, the upper end of described prismatoid is the inlet of inverted cone, the lower end of described prismatoid is connected with U-shaped frame, the bottom of described U-shaped frame is connected with ball by spring and blocks up, the external diameter that described ball blocks up is greater than the internal diameter of runner, tapping channel is formed between described U-shaped frame and inboard wall of tube body, the bottom of described U-shaped frame is communicated with the liquid outlet below U-shaped frame by secondary orifices, the lower end inwardly outstanding boss forming wedge shape of described body, outage is formed between described boss and described U-shaped frame, described boss is connected with described sprinkling tube head, described liquid outlet is communicated with sprinkling tube head.
The further technical scheme of this utility model is: the length of described sprinkling tube head is 2-3cm.
The beneficial effect that this utility model is taked above-mentioned technological means and produced is: gastroscope spray line of the present utility model, prismatoid and U-shaped frame are set in the bottom of body, block up coordinate with the runner in the middle of prismatoid by being arranged on spring on U-shaped frame and ball, making can only import but no export by the medicine of this gastroscope spray line, avoids the adverse current of medicine and gastric content.
Accompanying drawing explanation
Fig. 1 is the structural representation that gastroscope spray line of the present utility model is in sprinkling state.
Fig. 2 is that gastroscope spray line of the present utility model is in the structural representation stoping gastric content reverse flow state.
In figure, 1-body, 2-sprays tube head, 3-insecticide-spraying hole, 4-inlet, 5-prismatoid, 6-boss, 7-runner, 8-U type frame, 9-spring, and 10-ball blocks up, 11-outage, 12-tapping channel, 13-liquid outlet, 14-secondary orifices.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Gastroscope spray line of the present utility model as depicted in figs. 1 and 2, comprise body 1 and spray tube head 2, the tube wall of sprinkling tube head 2 is provided with some insecticide-spraying holes 3, the inwall of body 1 bottom is the prismatoid 5 of runner 7 in the middle of inwardly giving prominence to and being formed, the upper end of prismatoid 5 is the inlet 4 of inverted cone, the lower end of prismatoid 5 is connected with U-shaped frame 8, the bottom of U-shaped frame 8 is connected with ball stifled 10 by spring 9, the external diameter that ball blocks up 10 is greater than the internal diameter of runner 7, tapping channel 12 is formed between U-shaped frame 8 and the inwall of body 1, the bottom of U-shaped frame 8 is communicated with the liquid outlet 13 below U-shaped frame 8 by secondary orifices 14, the lower end inwardly outstanding boss 6 forming wedge shape of body 1, outage 11 is formed between boss 6 and U-shaped frame 8, boss 6 is connected with sprinkling tube head 2, liquid outlet 13 is communicated with sprinkling tube head 2.As preferably, the length of spraying tube head 2 is 2-3cm, and this length is convenient to medicinal liquid and is sprayed evenly and rapidly.
Gastroscope spray line of the present utility model prevents the process of gastric content adverse current as follows.
As shown in Figure 1, medicine is by runner 7 and impact that ball is stifled 10, after spring 9 compressed, medicinal liquid enters spray tube head 2 through tapping channel 12, outage 11 and secondary orifices 14, liquid outlet 13.As shown in Figure 2, self diastole closed flow 7 of sprayed rear spring 9, thus prevent driving in the wrong direction of gastric content and medicinal liquid.Gastroscope spray line of the present utility model, prismatoid 5 and U-shaped frame 8 are set in the bottom of body 1, block up 10 coordinate with the runner 7 in the middle of prismatoid 5 by being arranged on spring 9 on U-shaped frame 8 and ball, making can only import but no export by the medicine of this gastroscope spray line, avoids the adverse current of medicine and gastric content.
The above embodiment only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
