Description

Movable purification treatment instrument for excrement of bedridden patient

The technical field is as follows:

the invention belongs to the technical field of medical instruments, and particularly relates to a movable purification treatment instrument for excrement of a bedridden patient.

Background art:

because the bedridden patients can not self-care when defecating, the nursing staff is required to clean excrement generated by the bedridden patients, the nursing staff can diffuse in a room in the process of cleaning the excrement to cause indoor air pollution, the patients or the nursing staff in the room are victims of the air pollution, the discomfort and the risk of cross infection of the nursing staff are increased, meanwhile, the air purification time is more than half an hour, the excrement treatment is generally not closed, and the source of infection and smell still exists, in order to solve the problem, auxiliary equipment capable of treating the excrement is designed, for example, the bulletin number is as follows: CN208492554U, invention name: the nursing bed with the defecation facility, leave defecation mouth and defecation collection device in the centre of this kind of modified nursing bed, and in real life because patient bed upper berth has bed stigma or air cushion, the patient is the direct contact bed board, and these patents all can not avoid polluting, and difficult disinfection, do not fully consider used repeatedly in the design, so these patents can't put into use in reality, because excrement does not carry out sealing treatment in this kind of patent, can't avoid producing the pollution to the environment equally, so the practicality and the economic benefits of this kind of improved equipment are all lower. In addition, because malodorous gas in excrement mainly comes from indole, skatole, hydrogen sulfide and the like, most of the odor in the malodorous gas can be filtered through activated carbon treatment, but the sulfur-containing gas cannot be filtered, and the conventional nursing equipment does not have a device specially used for filtering the sulfur-containing gas.

The invention content is as follows:

the invention provides the movable purification treatment instrument for the excrement of the bedridden patient, which is convenient to operate, simple and practical, can be repeatedly used, does not cause the problem of cross infection after repeated use, and reduces the labor amount of nursing staff.

The technical scheme adopted by the invention is as follows: a movable purification treatment instrument for excrement of a bedridden patient comprises: the movable machine box is internally provided with a collecting system and a flushing system, the collecting system comprises an integrated excrement collecting bag, a gas filtering box, an activated carbon filtering box, a blower and a foldable gas collecting screen, after the air suction end of the integrated excrement collecting bag sucks excrement, solid and liquid excrement is retained in the integrated excrement collecting bag, malodorous gas generated by the excrement is discharged from the exhaust end of the integrated excrement collecting bag and then sequentially passes through the gas filtering box for filtering sulfur-containing gas and the activated carbon filtering box for filtering other gases, and the filtered purified gas is discharged from the movable machine box through the blower; the foldable gas acquisition screen give vent to anger the end and embed in portable quick-witted incasement, can form the arc screen after the vertical stretching of the other end, the end of breathing in of foldable gas acquisition screen is seted up on the lateral wall of arc screen, and the foldable gas acquisition screen is inhaled the foul gas that produces when excreting, sends into the gas filtration case in through the pipeline, rinse-system includes the squirt and is used for providing the constant temperature water tank of warm water for the squirt.

Preferably, foldable gaseous collection screen is including the telescopic joint, organ cover and the case that shelters from that connect gradually, the telescopic joint is cup jointed by a plurality of both ends open-ended hollow cuboid head and the tail and is constituteed, and evenly has laid the suction hole rather than inside intercommunication on every section of cuboid lateral wall near the patient, is equipped with the opening at the both ends of telescopic joint, the organ cover is with changing the position of sheltering from the case on portable quick-witted case.

Preferably, the bag is gathered to integral type excrement includes that a storage section of thick bamboo closes the cover at a storage section of thick bamboo top with the lid, is equipped with the collection handle and the connection port of giving vent to anger with storage section of thick bamboo inner chamber intercommunication at the top of cover, and the outer wall processing at the connection port of giving vent to anger has the external screw thread, has the internal thread at the processing of the end inner wall of breathing in of gathering the handle, and the end of breathing in of gathering the handle can realize threaded connection with the connection port of giving vent to anger.

Preferably, at least one zinc acetate filter core for filtering sulfur-containing gas is arranged in the gas filtering box.

Preferably, an air filter screen is arranged at the air outlet of the blower.

Preferably, a walking wheel with a self-locking function is arranged below the movable case.

The invention has the beneficial effects that:
