Abstract
The disposable medical sewage collecting bag consists of one bag; one cover with one sucking port, one air exhausting port and one bag expanding port not communicated to the holding space inside the bag; and one fixing ring. The collecting bag may be deflated through the bag expanding port to form one low pressure region outside the bag for the bag to expand automatically, so that the collecting bag can suck water continuously and bear certain water sucking pressure. The collecting bag is applied in different kinds of medical negative pressure suction apparatus, such as sewage sucking negative apparatus, phlegm sucking machine, stomach cleaning machine, etc.
Description
Technical field
The present invention relates to medical sewage collecting bag, particularly disposable medical sewage collecting bag.
Background technology
Usually medical sewage such as watery blood, pus, washing fluid, phlegm or body metabolism thing are collected by the mode that negative pressure source sucks during hospital surgical, modal method is to adopt negative pressure source that the liquid that these have a large amount of bacteriums and virus is attracted in the rigid container in the prior art, pour into then in the special medical sewage collecting jar, be transported to the medical sewage processing enter and handle, rigid container is then reused behind cleaning and sterilizing.
With electronic sputum aspirator is example (with reference to figure 1), and the rigid container that preparation is contained the sputum body is promptly buckled well snap close by the loam cake good seal earlier.Then sputum aspirator tube is inserted in the water-in of rigid container loam cake; With an air outlet that is inserted in the rigid container loam cake of extraction pipe, the other end is connected with negative pressure source by behind the air filter.After connecting power supply, open the switch of mechanical pump, mechanical pump is started working, and as negative pressure source, produces negative pressure.Extraction pipe is pumped into negative pressure with rigid container, like this, sputum aspirator tube is inserted throat or phlegm just can have been inhaled by lung.The sputum inhaled flows into rigid container, suck phlegm after, sputum is poured into the medical sewage treatment station of hospital and is handled; Perhaps pour in the special medical sewage collecting jar, be transported to the medical sewage processing enter and handle, rigid container is then reused behind cleaning and sterilizing.
Obviously, in said process, medical personnel will handle the sputum of collecting in the rigid container, and clean rigid container, and the rigid container that directly contacts contaminated causes medical personnel to pollute easily.
In order to address the above problem, the disposable sewage collecting bag that can adopt plastics film to make, but the disposable sewage collecting bag of plastics film manufacturing can not absorb water continuously or big suction suction.Though can before suction, try one's best disposable collecting bag (1) is launched, but the bag wall intensity of the disposable collecting bag that plastics film is made is too low, in water absorption course Plastic film Bag can on carry and the shutoff bleeding point, finally cause and can't absorb water, perhaps can only use low pressure, absorb water by phased manner.Need to utilize the own wt that has sucked water in the bag that disposable collecting bag is launched during this time.Obviously, this structure can not absorb water continuously or with big suction suction, can't satisfy needs clinically.Also lack in the prior art and a kind ofly not only can absorb water continuously, and can bear the disposable medical sewage collecting bag efficiently safe in utilization of bigger suction pressure.
Summary of the invention
The present invention aims to provide a kind of can the suction continuously, can bear the disposable medical sewage collecting bag efficiently safe in utilization of bigger suction pressure.
The object of the present invention is achieved like this:
Disposable medical sewage collecting bag, described disposable medical sewage collecting bag is made up of the interface of bleeding in collecting bag, loam cake, inhalation interface, the collecting bag, collecting bag expansion interface, set collar; Set collar is fixed on collecting bag hermetically and covers; The interface of bleeding in inhalation interface and the collecting bag is installed in loam cake, and is connected with the object space of receiving of the inside of collecting bag; Collecting bag launches interface and is installed in and covers, and is not communicated with the object space of receiving that the inside of loam cake and collecting bag is formed.
Further, on the interface of bleeding in described inhalation interface and the collecting bag switch is installed, prevents that medical sewage from flowing out.
Perhaps, bleed in described inhalation interface and the collecting bag and sealing cover is installed on the interface.Sealing cover can seal the interface of bleeding in inhalation interface and the collecting bag, prevents that medical sewage from flowing out.
Cover in the described suction to be equipped with and prevent that liquid overflows device, anti-liquid overflows device can prevent that medical sewage from overflowing.
Cover in the described suction handle is installed, conveniently lift.
In addition, in the described collecting bag water-absorbing material is arranged.Water-absorbing material can planar water, and the medical sewage of liquid is become colloid or solid, convenient transportation.
Described water-absorbing material contains High hydrophilous resin.Usually adopt the High hydrophilous resin of environmental sound.There are starch system (grafts, carboxymethylation etc.) High hydrophilous resin, cellulose-based (carboxymethylation, grafts etc.) High hydrophilous resin, synthesized polymer system (polyacrylic, polyethenol series, polyoxyethylene system etc.) High hydrophilous resin etc. selective.
Described water-absorbing material contains Bactericidal medicine.Bactericidal medicine can be killed bacterium in the medical sewage and virus, and medical sewage is carried out preliminary harmless treatment.
The present invention's disposable medical sewage collecting bag is made up of the interface of bleeding in collecting bag, loam cake, inhalation interface, the collecting bag, collecting bag expansion interface, set collar; Set collar is fixed on collecting bag hermetically and covers; The interface of bleeding in inhalation interface and the collecting bag is installed in loam cake, is connected with the object space of receiving of the inside of collecting bag; Collecting bag expansion interface is installed in and covers, and the object space of forming with the inside of loam cake and collecting bag of receiving is not communicated with.Launching interface by collecting bag bleeds, outside the collecting bag outer wall, form low pressure area, make collecting bag to launch automatically, and keep certain expansion power, can absorb water continuously thereby provide a kind of, can bear the disposable medical sewage collecting bag efficiently safe in utilization of bigger suction pressure.The present invention can use in various medical negative pressure suction devices, relates to the medicine equipment of negative pressure suction device as medical sewage vacuum extractor, sputum aspirator, paunch flusher, stream of people's machine, vaginadouche machine etc.
