The utility model relates to the field of medical instruments, in particular to a negative pressure drainage bag.
Background
The drainage bag is used for sucking and draining effusion, qi accumulation and concentrated blood generated by wounds during or after surgical operation or guiding pus, blood and body fluid accumulated between human tissues or in a body cavity to the outside. Because a large amount of pathogens such as bacteria or viruses possibly exist in the effusion in the patient cavity, the used negative pressure drainage bag needs to be disinfected and sterilized in time, and the effusion is prevented from leaking to threaten the health of medical staff, accompanying staff or other patients and family members.
The existing disposal schemes of the disposable negative pressure drainage bag are roughly divided into three types:
medical staff directly dismantles ingress pipe and the delivery tube of negative pressure drainage bag, directly discards to medical waste treatment department with sealed back of negative pressure drainage bag.
Medical staff cuts a small opening on the used negative pressure drainage bag, and the liquid in the negative pressure drainage bag is directly poured into a sewage disposal pipeline.
Medical staff can inject chlorine-containing disinfectant into the inlet of the negative pressure drainage bag by using a syringe according to a proportion for disinfection, and then the medical staff can discard the medical waste directly.
According to the first treatment method, the negative pressure drainage bag is sealed by disassembling the introducing pipe and the delivering pipe, so that the probability of pathogen contact of medical staff is greatly increased; in the second treatment method, after the medical staff cuts out the drainage port from the negative pressure drainage bag, pathogens such as bacteria or viruses in untreated drainage liquid in the negative pressure drainage bag can flow along with air transmission or pollute the environment, so that the opportunity of the medical staff to contact the pathogens is increased, and the environment pollution is easily caused; in the third treatment method, the liquid chlorine-containing disinfectant is injected through the injector, so that the operation is complex, and accidental leakage is easy to cause in the injection process.
Therefore, how to design a negative pressure drainage bag which is convenient to disinfect the accumulated liquid in the negative pressure drainage bag and is not easy to cause accidental leakage is a technical problem to be solved.
Disclosure of Invention
In order to solve the problems, the utility model aims to provide a negative pressure drainage bag, which solves the problems that the existing negative pressure drainage bag treatment method is high in safety risk and easy to cause unexpected leakage.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: comprises a main bag and a side bag which is arranged on one side of the main bag and is integrally formed with the main bag and used for containing chlorine-containing disinfectant; a barrier film is arranged between the main bag and the side bag; one end of the main bag opening is communicated with a drainage tube, and one end of the main bag bottom is communicated with a liquid discharge tube.
Further, the barrier film is ruptured by an external force to communicate the side pocket with the main pocket.
Further, scale marks for measuring the liquid accumulation capacity in the main bag are arranged on the surface of the main bag in the direction from the bottom of the bag to the mouth of the bag.
Further, drain valves are arranged on the drainage tube and the drain pipe in a clamping mode.
Further, a common wall is arranged between the main bag and the side bag, the main bag is connected with the side bag through the common wall, and the barrier film is arranged on the common wall.
Further, the material of the barrier film is different from the material of the common wall.
Further, the barrier film is provided with a virtual sealing edge.
The utility model has the following beneficial effects:
according to the utility model, the side bag, the main bag and the barrier film are arranged, the liquid discharge valve is closed after drainage is finished, and the barrier film is broken by pressing the side bag, so that the side bag is communicated with the main bag, and the accumulated liquid in the main bag is disinfected. In the process, medical staff and the effusion of patients are in non-contact, meanwhile, the liquid discharge valve is prevented from being opened or the drainage bag is prevented from being cut, chlorine-containing disinfectant is prevented from being injected, the possibility that pathogens such as bacteria or viruses in the effusion in the main bag pollute the environment along with air transmission and flow is avoided, and the use safety of the patients and the medical staff is improved.
The utility model has simple structure, convenient use and strong practicability.

Detailed Description
The utility model is described in further detail below with reference to the attached drawings and specific examples:
referring to fig. 1, the scheme comprises a main bag 1 and a side bag 2 which is arranged on one side of the main bag 1 and is integrally formed with the main bag 1 and used for containing chlorine-containing disinfectant; because the characteristics of the amount, the type, the color, the state and the like of the effusion led out by the patient body need to be observed in real time in the treatment process, the treatment scheme can be conveniently adjusted to follow the treatment progress, and the main bag 1 and the side bag 2 are made of one of transparent PP bags, transparent PE bags, transparent HDPE bags, transparent TPE bags and transparent PVC bags.
According to the capacity of the main bag 1, the number of the side bags 2 serving as the liquid storage space can be one or two, and the side bags are distributed on two sides of the main bag 1, so that the disinfectant with the content in the side bags 2 and the accumulated liquid in the main bag 1 can be conveniently mixed. A barrier film 3 is arranged between the main bag 1 and the side bag 2; the barrier film 3 is rupturable under external force to communicate the side bags 2 with the main bag 1 for the chlorine-containing sterilizing liquid contained in the side bags 2 to enter the main bag 1.
The connecting edge can be directly formed by the barrier film 3 between the main bag 1 and the side bag 2, so that the possibility of cracking of the barrier film 3 due to accidental impact or accidental extrusion in the transportation process is reduced to a certain extent, chlorine-containing disinfectant in the side bag 2 is effectively and independently stored to avoid entering the main bag 1 in advance, so that the disinfection effect is reduced, a shared wall 4 is arranged between the main bag 1 and the side bag 2, the main bag 1 is connected with the side bag 2 through the shared wall 4, and the barrier film 3 is arranged on the shared wall 4.
The separation of the separation film 3 under the action of external force has various implementation modes, and in the embodiment, the mode that the structural strength of the separation film 3 is lower than that of the shared wall 4 is selected, so that the separation film is simple in structure and easy to implement. Specifically, the material of the barrier film 3 is different from the material of the common wall 4, the mechanical strength of the material of the barrier film 3 is lower than that of the common wall 4, so that the barrier film 3 is broken under the action of external force, and the barrier film 3 can be broken by pressing the side bag 2 by hands of medical staff or folding the side bag 2 along the common wall 4, and the chlorine-containing disinfectant in the barrier film 3 flows to the main bag 1; the barrier film 3 may be provided with a dummy edge, and the dummy edge may be of a complete structure when no external force is applied, and may be broken when external force is applied, so that the side bag 2 and the main bag 1 communicate.
One end of the bag mouth of the main bag 1 is communicated with a drainage tube 11, and one end of the bag bottom of the main bag 1 is communicated with a liquid discharge tube 12. The drainage tube 11 and the drainage tube 12 are integrally formed with the leading-in end and the leading-out end of the main bag 1 or embedded in the inner cavity of the main bag 1, and a sealing space is formed in the main bag 1.
