Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an enema decompression structure and an enema device for patients with intestinal obstruction. Background Art

[0002] Intestinal obstruction refers to a disease caused by the inability of intestinal contents to pass normally due to narrowing, blockage or peristalsis of the intestinal lumen. Common symptoms include abdominal distension and pain, nausea and vomiting, constipation or inability to pass gas, etc. Intestinal obstruction may be caused by tumors, inflammation, colon torsion, mesenteric vascular embolism, etc. Severe intestinal obstruction requires immediate medical treatment; treatment methods include eliminating the cause of intestinal obstruction, clearing intestinal contents, and rehydrating to maintain water and electrolyte balance.

[0003] Enema treatment is a commonly used auxiliary treatment method for patients with intestinal obstruction in clinical practice. The purpose of enema is to stimulate the patient's colon and promote the discharge of the contents accumulated in the colon. With existing enema devices, the speed of liquid input into the patient's body is relatively fast, and the enema device usually adopts a drip-like method, hanging the liquid at a high place and injecting it through an infusion line. When the liquid in the patient's intestine cannot flow smoothly and temporarily accumulates in a certain position, the pressure at that position will increase rapidly, and this change cannot be seen from the outside of the body. If the liquid input continues, a large pressure will be produced at the accumulation point, which may cause intestinal rupture in patients in severe cases.

[0004] Therefore, how to design an enema decompression structure and enema device for patients with intestinal obstruction that can reduce pressure when performing enema on patients with intestinal obstruction is a technical problem that has not yet been solved in the prior art. Utility Model Content

[0038] 3. The utility model is an enema decompression structure for patients with intestinal obstruction. The three-way connector includes a cylindrical main body, a first connecting tube and a second connecting tube are respectively arranged at the two axial ends of the cylindrical main body, and the third connecting tube is arranged in the middle; the liquid enters from the second connecting tube and is discharged from the first connecting tube.

When the liquid entering the human body cannot continue to flow due to blockage somewhere in the intestine, and the liquid continues to be input into the human body, pressure will be generated in the intestine. As the liquid is continuously input, the pressure in the intestine will become greater and greater. When the pressure reaches the set value, the liquid will push the sealing pad to squeeze the spring, causing the sealing pad to move to a position below the liquid outlet tube, and the liquid is discharged from the liquid outlet tube to reduce the pressure in the intestine. The discharge of the liquid from the liquid outlet tube can also remind the doctor to take effective measures in time to avoid intestinal rupture.

[0042] That is to say, when performing enema on patients with intestinal obstruction, the utility model can not only remind medical staff that the pressure in the patient's intestine is too high when the pressure in the intestine reaches the set value, but also temporarily relieve pressure to reduce the pressure in the intestine and avoid intestinal rupture.

[0043] 6. The enema device for patients with intestinal obstruction of the utility model has a liquid inlet at the bottom of the infusion bag, and when performing enema on the patient, liquid can be poured in or supplemented from the liquid inlet.

Example 2

[0068] This embodiment provides an enema device for patients with intestinal obstruction, such as Figure 1As shown, it includes: an infusion bag 7, a third pipeline 6, a first pipeline 2 and a decompression structure 3; wherein the infusion bag 7 includes an infusion bag body 71, and a liquid outlet 73 arranged at the top of the infusion bag body 71; the second end of the third pipeline 6 is connected to the infusion bag 7; the second end of the first pipeline 2 is suitable for inserting a soft needle 8 into the human body; it also includes a decompression structure 3, and the decompression structure 3 is the decompression structure 3 described in Example 1; the first end of the third pipeline 6 is connected to the second connecting tube 12, and the first end of the first pipeline 2 is connected to the first connecting tube 11.

[0069] During use, the liquid flows from the liquid outlet 73 of the infusion bag 7 along the third pipeline 6 to the first pipeline 2, and enters the human body from the second end of the first pipeline 2. When the liquid entering the human body cannot continue to flow due to a blockage somewhere in the intestine, and the liquid continues to be input into the human body, pressure will be generated in the intestine. As the liquid is continuously input, the pressure in the intestine will become greater and greater. When the pressure reaches the set value, the liquid will push the sealing pad 31 to squeeze the spring 33, so that the sealing pad 31 moves to the position below the liquid outlet pipe 14, and the liquid is discharged from the liquid outlet pipe 14 to reduce the pressure in the intestine. The discharge of the liquid from the liquid outlet pipe 14 can also remind the doctor to take effective measures in time to avoid intestinal rupture.

[0070] That is to say, when performing enema on patients with intestinal obstruction, the enema device of this embodiment can not only remind medical staff that the pressure in the patient's intestine is too high when the pressure in the intestine reaches the set value, but also temporarily relieve pressure to reduce the pressure in the intestine and avoid intestinal rupture.

When the liquid entering the human body cannot continue to flow due to blockage somewhere in the intestine, and the liquid continues to be transported into the human body, pressure will be generated in the intestine. With the continuous input of liquid, the pressure at the blocked part of the intestine will become greater and greater. When the pressure reaches the set value, the liquid will push the sealing pad 31 to squeeze the spring 33, so that the sealing pad 31 moves to the bottom of the liquid outlet pipe 14, and the liquid is discharged from the liquid outlet pipe 14 to reduce the pressure in the intestine; the discharge of liquid from the liquid outlet pipe 14 can also remind the doctor to take effective measures in time to avoid intestinal rupture.
