Description

Technical Field

[0001] The utility model relates to the technical field of enema intubation for congenital megacolon in infants, in particular to an enema intubation for infants and young children. Background Art

[0002] The enema intubation for infants and young children is one of the common methods for diagnosing congenital megacolon. Congenital megacolon is a disease with abnormal intestinal development at birth, which can cause symptoms such as intestinal flatulence and constipation. The enema intubation can check whether there is obstruction or dilation in the intestine by inserting a thin tube into the anus and then injecting liquid into the intestine.

[0003] After retrieval, a special enema device for pediatric internal medicine with the publication number CN211561304U; includes an enema intubation, one end face of the enema intubation is fixedly provided with a contact head, the other end of the enema intubation is fixedly connected with a first pressing ear, and its outer surface is provided with a first scale, and the first scale represents the distance between the right end face of the enema inner tube in the working state and the scale; the contact head is an elastic contact head, and a through hole is opened in the middle of the contact head. An enema inner tube is arranged inside the enema intubation. One end face of the enema inner tube close to the contact head is provided with a wedge head. The outer surface of the enema inner tube close to the other end face is fixedly provided with a second pressing ear. An external thread is arranged on the outer surface of the enema inner tube on the left side of the second pressing ear. The enema inner tube is threadedly connected with a syringe barrel. The right end face of the syringe barrel is fixedly provided with a connecting pipe, and an internal thread is opened on the inner surface of the connecting pipe. The utility model solves the problems that in the traditional enema process, it is not easy to control the enema depth through the enema tube, and the enema tube is easy to damage the patient's skin.

[0004] Based on the above patent, by setting special scale lines on the enema intubation, it is ensured that the enema intubation can accurately instill the enema liquid to the position where it needs to be instilled, so as to improve the more efficient treatment of the patient's affected area. At the same time, the enema inner tube can act as the needle of a traditional syringe to extract the liquid medicine when opening the bottle cap of the liquid medicine storage container. Through the setting of the enema intubation and the enema inner tube, it can be ensured that the enema inner tube will not damage the internal skin of pediatric patients. When the enema intubation is inserted to a specific depth in the intestine of pediatric patients, by squeezing the first pressing ear and the second pressing ear, the wedge head of the enema inner tube is passed through the contact head, so as to achieve the purpose of inputting the enema liquid. Since this device will not pierce the patient's skin, it can be reused after disinfection. The use process is convenient, the operation is simple, and it is environmentally friendly. However, when using the above patent product to detect infants, when the syringe barrel injects the enema liquid into the infant's body, if the injection speed is too fast, it is easy to make the discharged fluid make the infant feel uncomfortable, causing the infant not to cooperate with the corresponding examination and affecting the progress of the work. And the connection method of the pipeline and the syringe barrel of this device is a threaded connection. After long-term use, it is easy to cause thread wear and affect the connection and use of the pipe body and the syringe barrel. Summary of the Utility Model
