Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary instrument technical field, concretely relates to a backflow enema negative pressure drainage device. BACKGROUND

[0002] Hirschsprung disease is a common congenital intestinal malformation in children, and the incidence rate is about 1 / 5000. The pathogenesis is that the distal myenteric ganglion cells of the affected intestinal segment are absent or reduced, which causes the intestinal canal to lose normal peristalsis and be in a spastic and narrow state, forming functional intestinal obstruction. The intestinal contents are difficult to pass through, and the feces stagnate in the proximal intestinal segment, causing the proximal intestinal segment to expand and secondary compensatory hypertrophy. At present, the recognized treatment method for Hirschsprung disease is still surgery, and backflow enema is essential for preoperative intestinal preparation. However, there are times when backflow enema fails in clinical work, that is, the child's abdominal distension does not decrease or no fecal residue is discharged after enema, thereby affecting the surgical effect.

[0003] During the specific enema, the child is placed in a left lateral decubitus position or lithotomy position to facilitate the smooth passage of the enema solution through the narrow segment of the intestinal cavity into the dilated segment. The enema bag is hung on the infusion stand, and after the air is exhausted, the flow rate regulator is closed. The distance from the liquid surface to the anus is 40-60 cm. According to the results of the colonography examination, the dilated segment and the narrow segment are determined, and the distance from the dilated segment position is measured to determine the insertion depth. The anal canal is slowly and gently inserted into the anus, and when the anal canal reaches the dilated segment through the narrow segment, there is a sense of emptiness or feces overflow. At this time, the anal canal is properly fixed, the enema solution one end regulator is opened, and the enema solution is started to drip. Due to the child's long-term difficulty in defecation, the stool is dry and hard, and fecalith is formed in the intestinal cavity. The traditional backflow enema has the disadvantages of time-consuming, labor-intensive, difficult, and poor effect. CONTENT OF THE UTILITY MODEL

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a backflow enema negative pressure drainage device, which effectively solves the problem of poor defecation effect of the child during backflow enema.

[0005] The technical solution solved is that the utility model includes a connecting block, a enema sleeve is detachably connected to the upper end of the connecting block, the lower side of the enema sleeve is funnel-shaped with a large upper end and a small lower end, an insertion tube is fixed to the upper end of the enema sleeve and communicates with the enema sleeve, an oval-shaped air bag pad is fixed to the outer end of the lower side of the enema sleeve, a flexible expansion air bag is detachably connected to the lower end of the connecting block, a waste liquid cylinder is fixed to the lower end of the flexible expansion air bag, a connecting hole is formed through the upper side wall of the waste liquid cylinder and the flexible expansion air bag, a baffle is hinged to the upper side wall of the waste liquid cylinder and the flexible expansion air bag through a shaft, the baffle can block the lower side of the connecting hole, a moving block that can slide left and right is arranged in the connecting block, a circular groove is formed through the moving block, an L-shaped groove is formed in the right side of the moving block, the upper end of the circular groove can communicate with the enema sleeve, the lower end of the circular groove can communicate with the connecting hole, the upper end of the L-shaped groove can communicate with the enema sleeve, and a connecting pipe that penetrates through the connecting block is fixed to the right end of the L-shaped groove.

[0006] This utility model has a reasonable structure and is easy to use. It allows medical staff to easily aspirate the enema fluid after administering it to children, preventing some children's feces from failing to flow out with the enema fluid. During treatment, the enema fluid is quickly and thoroughly aspirated, with a balanced inflow and outflow, saving time and effort and significantly shortening the enema time. It also features a shielding airbag, an enema sleeve, and an insertion tube, which facilitates the shielding of the patient's anus during the enema, preventing waste fluid leakage and contamination of the ward environment. This is beneficial for medical staff to perform subsequent cleaning and nursing operations. It is also easy for medical staff to connect to the enema bag, allowing for repeated enema and aspiration operations on children, avoiding the discomfort caused by repeated intubation. It is convenient for medical staff and patients to operate and use. This structure is simple, easy to operate, novel in design, and highly practical. Attached Figure Description
