Description

Technical Field

[0001] The utility model relates to the field of enema, in particular to an enema device. Background Art

[0002] In clinical practice, in order to facilitate the diagnosis and treatment of some diseases of the digestive system, patients are sometimes required to perform enema. A common enema measure is to use a flushing bag for enema. This flushing bag is filled with flushing liquid, and a flushing tube is provided under the flushing bag. When performing an enema, the flushing tube needs to be inserted into the intestine through the patient's anus, and then the valve on the flushing tube is opened to send the flushing liquid into the human body.

[0003] This method uses simple equipment and is not complicated to operate, so it is widely used. However, there are the following problems in operation: 1. The flushing tube used is a plastic hose, which is easy to bend and deform. During the insertion into the anus, a lot of lubricant is often applied to achieve smooth insertion, which is difficult; 2. This method of using gravity alone to achieve flushing fluid flow often results in insufficient pressure, and the patient's intestines are obstructed, resulting in flushing fluid reflux, which prevents the flushing fluid from flowing smoothly into the human body. Therefore, improvements are needed. Utility Model Content

[0028] like Figure 1-Figure 4 The enema device shown comprises: a flushing bag 1, an inflatable balloon 2, an inflating tube 3, a liquid delivery tube 4, an insertion tube 5 and a guide strip 6.

[0029] An inflation tube 3 connected to the flushing bag 1 is provided at the upper end of the flushing bag 1 , an inflation balloon 2 is provided on the inflation tube 3 , the flushing bag 1 is filled with flushing liquid, and a liquid delivery tube 4 is provided at the lower end of the flushing bag 1 .

[0030] like Figure 2-Figure 4 As shown, one end of the insertion tube 5 is open and the other end is closed. An annular liquid injection groove 8 is provided inside the tube wall of the insertion tube 5 to form a sandwich structure. The liquid injection groove 8 extends along the length direction of the insertion tube 5. The liquid delivery tube 4 is integrally arranged on the side of the insertion tube 5 and the liquid delivery tube 4 is connected with the liquid injection groove 8. A plurality of drainage holes 7 connected with the liquid injection groove 8 are provided on the end face of the closed end of the insertion tube 5; the guide strip 6 is a slender strip with a certain rigidity, and the guide strip 6 can be detachably inserted into the insertion tube 5 through the open end of the insertion tube 5.

[0031] Specifically, the device still adopts the method of using the flushing bag 1 for enema in the prior art, but improves the relevant structure.

[0032] First, a straight tube originally arranged under the flushing bag 1 is changed into a Y-shaped tube composed of a liquid delivery tube 4 and an insertion tube 5, wherein the insertion tube 5 is designed as a sandwich structure, and the hollow area of ​​the internal sandwich is a liquid injection groove 8 connected to the liquid delivery tube 4, and a liquid discharge hole 7 connected to the liquid injection groove 8 is arranged at the closed end of the insertion tube 5, so that when performing enema, the flushing liquid can flow to the liquid injection groove 8 through the liquid delivery tube 4, and finally be discharged into the human intestine through the liquid discharge hole 7; and a slender guide strip 6 is inserted into the insertion tube 5, and the guide strip 6 has a certain rigidity, so that the insertion tube 5 can be easily inserted into the patient's anus, which greatly reduces the difficulty of enema insertion.

[0033] Secondly, in order to be able to smoothly press the flushing liquid into the human intestine, an inflation tube 3 and an inflation balloon 2 are added above the flushing bag 1, so that the flushing bag 1 can be inflated by pressing the inflatable balloon 2 to increase the air pressure in the flushing bag 1, thereby forcing the flushing liquid into the human body.

[0034] In this device, if Figure 1As shown, the inflation tube 3 is provided with a first one-way valve 9 and a second one-way valve 10, and along the inflation direction, the first one-way valve 9 is provided on the upstream side of the inflation balloon 2, and the second one-way valve 10 is provided on the downstream side of the inflation balloon 2. Specifically, when the inflation balloon 2 is pressed, the first one-way valve 9 is closed and the second one-way valve 10 is turned on, thereby realizing the inflation of the flushing bag 1; when the inflation balloon 2 is released, the first one-way valve 9 is opened and the second one-way valve 10 is closed, thereby realizing the automatic recovery of the inflation balloon 2, thereby realizing the one-way inflation of the flushing bag 1 and ensuring the inflation effect.

[0035] In the device, the liquid delivery tube 4 is provided with a third one-way valve 11, which is used to prevent the backflow of flushing liquid during enema; the guide strip 6 is a metal strip, and the liquid delivery tube 4 and the insertion tube 5 are integrally formed plastic hoses.
