[Detailed description of the device]

[Industrial applications]

The present invention relates to a device for filling the large intestine with air or a drug solution for examining the large intestine.

[Prior art]

In recent years, colorectal diseases have increased remarkably with the westernization of eating habits, and the frequency of colorectal examinations such as colonoscopy and enema fluoroscopy has significantly increased. To improve the reliability of these tests, clean the vagina in the large intestine during the test, and
It is important to distribute barium sulfate etc. evenly in the large intestine. To achieve this, a device is used that fills the anus and large intestine with barium sulfate and air before the examination. The conventional liquid filling device for enema fluoroscopy is
The catheter for enema, the hose connected to the rear end of the catheter for enema, and the filling container to which the hose is connected are provided. These are integrated, and the rotation of the patient necessary for sufficiently adhering barium sulfate to the intestinal wall at the time of examination is inconvenient. Further, there is a method of immediately removing or indwelling the enema catheter after injecting barium sulfate and air, but in the case of immediate removal, the injected barium sulfate and air cannot be excreted. When indwelling, there is a drawback that the movement of the patient on the X-ray fluoroscope becomes sluggish. When this apparatus is used to inject barium sulfate and air into a patient and then excrete these, it is used in the following state. A filling container filled with barium sulfate and air is connected to the enema catheter via a hose. Insert an enema catheter into the anus. Press the filling container and slowly inject barium sulfate and air from the anus into the large intestine. Remove the enema catheter from the anus. The injected barium sulfate is evenly distributed on the inner surface of the large intestine of the patient. For this purpose, the patient's body can be moved, for example by rotating it. X-ray of the large intestine is taken.

[Problems to be solved by the device]

In the conventional medical fluid filling device for enema fluoroscopy used in this state, air in the large intestine cannot be often exhausted after the examination.
Although there is an enema device capable of discharging air from the large intestine, this device has the drawback of being extremely expensive and complicated to operate. Therefore, in reality, after the examination, the air in the large intestine is not forcedly excreted but is naturally excreted. It takes half a day before air is excreted from the large intestine. During this time, the patient must endure the feeling of being hungry and uncomfortable. It is also possible to insert an enema catheter into the anus until the X-ray examination is completed and to excrete it from the large intestine after the examination is completed. However, when used in this state, the patient has to perform a rotational motion on the X-ray table in order to uniformly attach barium sulfate to the large intestine to the intestinal wall, but the conventional device has this movement because of the connecting tube. It has the drawback of becoming difficult. This is because the patient can be moved while the enema catheter, hose and filling container are connected to the anus. Further, in enema fluoroscopy, artificially injecting barium sulfate and air to a non-physiological range to take a photograph, after the inspection, the injected barium sulfate and air remain in the intestinal tract,
Unpleasant sensations such as abdominal bloating remain. This invention was developed for the purpose of solving these drawbacks of the conventional liquid medicine filling device for enema fluoroscopy, and an important object of this invention is to allow the patient to move freely. The purpose of the present invention is to provide a drug solution filling device for enema fluoroscopy that can eliminate abdominal pain of a patient and discomfort such as abdominal distension that occurs after the test by artificially eliminating air and the like in the large intestine after the test. . Further, another important object of the present invention is to provide a drug solution filling device for enema fluoroscopy that can shorten examination time, reduce X-ray exposure dose, and prevent overlooking of lesion by accurate radiograph. To do.

The filling / discharging container 4 provided with the temperature of the temperature sensor has a feature that the temperature of barium sulfate can be accurately confirmed, so that it can be used comfortably while preventing danger.

[Effect of device]

The drug solution filling apparatus for enema fluoroscopy of the present invention, after completing the large intestine examination, connects the hose connected to the filling / discharging container through the detachable connecting tool to the enema catheter and uses the filling / discharging container to enter the large intestine. The air, barium sulfate, etc. can be simply and easily discharged into the filling and discharging container quickly. Therefore, there is a feature that it is possible to eliminate abdominal pain and discomfort such as bloating of the patient that occurs after the examination. This is important when performing enema fluoroscopy. In order to perform a radiographic examination of the large intestine, barium sulfate and air are injected up to a non-physiological range and a photograph is taken.Therefore, as in the conventional inspection device, a large amount of barium sulfate and air are intestinal tract after the inspection. The reason is that if left inside, discomfort such as abdominal pain and bloating cannot be resolved for a long time. Further, the drug solution filling apparatus for enema fluoroscopy of the present invention connects the filling and discharging container to the rear end of the enema catheter via the detachable connector and the hose, so that the enema catheter can be connected to the anus of the patient. Insert, put the blocking member in the non-blocking state, inject the drug solution or air from the filling and discharging container into the large intestine of the patient, and then
The hose and fill and drain container can be separated from the enema catheter by closing the rear end of the enema catheter.
That is, the hose and the filling / discharging container can be removed while leaving the enema catheter as it is. Therefore, the patient can move freely in this state, barium sulfate can be evenly attached to the intestinal wall, and an X-ray image can be taken in this state. That is, in the drug solution filling device for enema fluoroscopy of the present invention, since the enema catheter left on the patient side is short, the patient's rotational movement can be smoothed,
Further, the amount of barium sulfate and the amount of air can be appropriately increased or decreased during the inspection. Therefore, when a radiographic examination of the large intestine is performed using the drug solution filling device of the present invention, the time for irradiating the patient with X-rays and the examination time can be shortened, and the X-ray exposure dose can be reduced.
Furthermore, it has the features that adhesion of barium to the intestinal wall is improved, accurate radiographs can be taken, and lesions can be overlooked. Furthermore, the drug solution filling device for enema fluoroscopy of the present invention,
The disposable type helps prevent infection from the anus and the intestinal tract, and the labor for cleaning and disinfecting can be omitted.
