Description
Technical Field
The utility model belongs to the field of medical equipment, especially, relate to a disposable negative pressure drainage bag.
Background
The negative pressure drainage device is mainly used for medical drainage, sputum excretion, blood and secretion excretion and the like. The vacuum drainage device utilizes the vacuum working principle to enable the pressure in the cavity of the negative pressure drainage device to be lower than the pressure in the cavity of a patient, so that liquid which is not beneficial to the rehabilitation of the patient body is guided out, the rehabilitation progress of the patient is accelerated, and the cure rate of the patient is improved.
The negative pressure drainage device is provided with a negative pressure drainage bag as a cavity structure for generating negative pressure and is used for storing dirt (such as dirty blood, phlegm and the like) led out from the body of a patient. Because the effusion in the disease cavity may have a large amount of pathogens such as bacteria or viruses, the effusion is guided into the negative pressure drainage bag to be disinfected and sterilized in time, thereby avoiding the pathogens from leaking out and threatening the health of medical care personnel, accompanying personnel or other patients and family members.
The existing disposal schemes of the disposable negative pressure drainage bag are three, which are respectively:
1, after using the drainage bag, medical personnel dismantle and cover the induction tube and the delivery tube of negative pressure drainage bag, directly abandon as medical waste.
2, after the drainage bag is used, the medical staff cuts the small opening of the negative pressure drainage bag and directly pours the small opening into a sewage disposal pipeline.
3, after the drainage bag is used, the medical staff injects chlorine-containing disinfectant into the negative pressure drainage bag inlet according to the proportion by using an injector for disinfection, and then the disinfection is directly discarded as medical waste.
Because pathogens such as bacteria or viruses and the like possibly flow along with air transmission or pollute the environment, the drainage liquid which is not treated is directly discarded or cut, and the risk of infection or environmental pollution is caused to operators; the liquid chlorine-containing disinfectant is injected by the injector, so that the operation is complicated, and accidental leakage is easily caused in the injection process; therefore, a solution for sterilizing the accumulated liquid in the disposable negative pressure drainage bag under the condition of keeping the sealed state of the drainage bag is needed.
SUMMERY OF THE UTILITY MODEL

Two communicating holes 52 are arranged on the inner cover 5; the two communication holes 52 are respectively arranged corresponding to the two ports to ensure that the lead-in port 23 and the lead-in port 23 are both communicated with the inner cavity of the bag body 1; avoid the inner cup 5 to block leading-in port 23 and/or leading-out port 24 and the inner chamber intercommunication of bag body 1, and lead to the internal hydrops of disease can't lead out.
Based on the scheme, as shown in fig. 8, when the disposable negative pressure drainage bag is discarded after being used and sterilized, two ports need to be sealed to avoid leakage of accumulated liquid in the bag; thus, in one embodiment, the inlet port 23 and/or the outlet port 24 is fitted with a sealing plug 25. The sealing plug 25 includes a plug body 251 detachably embedded in the inner cavity of the two-port cylindrical tube, a ring sleeve 252 sleeved on the periphery of the two-port cylindrical tube, and a flexible connecting member 253 connecting the plug body 251 and the ring sleeve 252.
The plug body 251 is used for being plugged into the inner cavity of the tube body of the leading-in port 23 or the leading-out port 25 to seal the leading-in port 23 or the leading-out port 24 in an embedded mode, and effusion leakage in the drainage bag is avoided. The plug body 251 is connected with a ring sleeve 252 through a flexible connecting piece 253, and the ring sleeve 252 is used for being sleeved on the outer side walls of the two-port tube body to fix the whole sealing plug 25, so that the plug body 251 with smaller volume is prevented from being lost.
In this embodiment, the plug 251, the flexible connecting member 253, and the ring sleeve 252 are all made of one of PP, PE, HDPE, TPE, or PVC, and the like, have a certain flexibility, can generate slight elastic deformation, have a good sealing effect, and can be integrally formed by an injection molding process, and have a simple manufacturing process and a low cost.
