Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a negative pressure rectal membrane type drainage device.
Background
At present, rectal cancer is clinically treated, a patient usually adopts a rectal resection, complications such as anastomotic infection or anastomotic leakage easily exist after the rectal resection is performed, and intestinal contents of a serious patient leak through the anastomotic defect, so that the abdominal cavity of the patient is infected. According to statistics, the incidence rate of clinical anastomotic leakage is about 1-3%, the patient is delayed to be discharged in mild cases, and the life of the patient is threatened in severe cases. In order to avoid the contamination of the anastomotic orifice with excreta and the resulting infection of the anastomotic orifice, the anastomotic orifice generally needs to be protected. The existing protection anastomotic stoma is commonly made by the following steps: the last ileum or transverse colon of a patient is lifted out of the main abdominal wall, a protective enterostomy is made on the abdominal wall of a human body, excrement is diverted, and after an anastomotic stoma at the rectum is healed, a secondary operation is performed to restore the intestinal tract. However, the above-mentioned operation requires a secondary reduction operation, which causes secondary damage to the patient. And the whole rehabilitation period is as long as half a year, thus undoubtedly increasing physical and psychological pains and medical expenses of patients. At present, a plurality of rectal drainage tubes appear clinically in succession, but the drainage tubes cannot ensure that the intestinal fluid at the proximal end of the anastomotic stoma is completely diverted due to the structural defects, and the excrement is retained in the intestinal cavity of the rectum and still has the risk of polluting the anastomotic stoma.
SUMMERY OF THE UTILITY MODEL
The utility model provides a rectum negative pressure film type drainage device for solving the technical problems in the prior art, which is used for protecting an anastomotic stoma in rectal resection, wherein excrement is drained from the inside of the device and does not contact the anastomotic stoma of a patient in surgery, when the anastomotic stoma of the patient leaks, the excrement can be prevented from entering an abdominal cavity from the colostomy, the colostomy can be healed by the patient for sufficient time, and the wound and the strike of a secondary operation in a short time after the rectal resection are avoided.
The technical scheme adopted by the utility model for solving the technical problems in the prior art is as follows:
rectum negative pressure membrane drainage device, its characterized in that: collect bag, check valve and stationary vane including a pair of collection ring, a pair of film drainage cover, drainage tube, drainage, the collection ring is the loudspeaker form, and every collection ring osculum is terminal and film drainage cover rigid coupling, and one of them film drainage cover plug-in mounting is inside adjacent collection ring, and drainage tube and drainage collection bag are connected gradually to the external tip of another film drainage cover, the system has the negative pressure chamber on the lateral wall of collection ring, and the system has one at least negative pressure location on collecting the ring surface and inhales the groove, negative pressure location inhales the negative pressure chamber intercommunication on groove and the collection ring lateral wall, negative pressure chamber intercommunication negative pressure suction pipe.

Preferably, the connection part of the drainage tube and the outer end of the film drainage sleeve of the second collecting ring is provided with a fixed wing convenient for being fixed with the body of a patient.
The utility model has the advantages and positive effects that: because adopt double-deck collection ring structure, and the collection ring opening is the loudspeaker form, wall thickness and diameter can change, can adapt to the intestinal cavity of unidimensional, and the negative pressure effect makes collection ring and intestinal wall closely laminate, can collect the intestinal cavity content completely, and is not remained and reveals safer. The thin film drainage sleeve is soft and has good compliance, and excrement can be smoothly discharged after being expanded; when no excrement exists, the whole body is reduced, the occupied space is small, and the foreign body sensation in the intestines is reduced. The negative pressure positioning suction groove is arranged on the surface of each collecting ring and surrounds the collecting ring for a circle, so that the intestinal cavity of a patient can be placed conveniently, and the damage to the intestinal wall of the patient can be reduced. The side wall groove structure of the collecting ring enables the intestinal wall mucosa to be easily attached and fixed, and the intestinal wall mucosa is easily peeled off when the collecting ring needs to be taken out after use, so that the collecting ring is convenient to take out. The negative pressure positioning suction grooves with different diameters can be adapted to intestinal lumens with different thicknesses, so that intestinal juice can be more effectively prevented from leaking from the side. The negative pressure suction tube has smaller diameter, is convenient to be attached to the outer side of the film drainage sleeve and led out of the body, reduces the foreign body sensation of a patient, and reduces the influence on the anus contraction function. The fixed wings can fix the drainage tube in vitro, ensure the positioning of the drainage tube and facilitate the movement of the patient. The collecting ring, the film drainage sleeve, the drainage tube and the drainage bag form a closed and smooth channel, so that the contents in the intestinal cavity do not contact with the anastomotic stoma in the whole drainage process, the collecting process is safer, and the intestinal anastomotic stoma is effectively protected.
