Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a disposable humidification bottle system for a medical oxygen inhalator.
Background
Medical oxygen inhalator (hereinafter referred to as inhalator) is a basic oxygen supply device commonly used in medical institutions, and is used for emergency oxygen supply and comfortable oxygen therapy by supplying humidified oxygen to patients. The inhalator mainly comprises a flow meter capable of adjusting oxygen flow and a humidifying bottle filled with humidifying liquid. The flow meter can be a float type oxygen flow meter or a digital type oxygen flow meter. The automatic pressure relief device which is required to be forcibly equipped in the inhaler can be arranged on a flowmeter and can also be arranged on a humidification bottle.
The following is described in the document entitled "method for managing oxygen-containing humidification fluid J" (from the journal of Chinese nursing, 2001,36(7): 542), written by Zhang Chun Xian, Wang Xijun, Zhang Jing et al: medical oxygen (no matter liquid oxygen or medical oxygen prepared by a molecular sieve) contains about 10 percent of moisture due to the preparation process, the physiological requirement of human breathing cannot be met, the medical oxygen is not suitable for being directly supplied to a patient, the medical oxygen and humidifying liquid are mixed in a humidifying bottle in a physical mode, aerosol containing more moisture is formed to be humidifying oxygen, the humidifying oxygen enters the respiratory tract of the patient in a humidifying oxygen form, stimulation of dry oxygen to the respiratory tract mucous membrane is avoided, the compliance of oxygen inhalation of the patient is increased, and the oxygen therapy effect and the comfort degree of patient treatment are improved.
In order to meet the requirement that the inhalator normally humidifies oxygen, sterile water is required to be filled in the humidification bottle to serve as humidification liquid, the operation of adding the humidification liquid into the humidification bottle is usually carried out by nurses at the bedside of a hospital ward or in a treatment room, non-fermentation pathogenic bacteria such as escherichia coli, salmonella, staphylococcus aureus, pseudomonas aeruginosa, mould and the like in the air of the ward are generated, or the air of the ward is not sufficiently sterilized, or the injected humidification liquid carries bacteria, or the humidification bottle is not sterilized normally, the bacteria can enter the humidification bottle along with the air or the humidification liquid, and can be rapidly propagated in the humidification bottle in an oxygen-enriched environment. After the patient inhales humidified oxygen infected by germs, respiratory tract infection is easily caused, and the disease is aggravated.
Respiratory tract infection accounts for the first in the nosocomial infection cases in China (reference document: 164 cases of nosocomial lower respiratory tract infection analysis J authored by Zhang Fengqin,derived from the journal of infectious diseases of Chinese hospitals, 1996,6(1): 30-31), wherein the treatment of device infection by humidifying liquid, medical devices and the like is a non-negligible factor causing pulmonary complications (reference: the author is Lu Si's comparison J of clinical application of traditional Chinese medicine oxygen humidification liquid and traditional oxygen humidification liquid, which is from J of occupation and Kekang, 2003,19(5): 112-113). The research shows that: the pollution rate of the oxygen humidifying liquid is as high as (60-80)%, and the bacterial content can be more than 2 multiplied by 10 per milliliter4The detection rate of pathogenic bacteria is up to 20 percent (the reference document: the bacteriological investigation and disinfection method J of an oxygen humidification bottle by the author of Wangshujun comes from the journal of Chinese nursing, 1994,2(1): 12).
According to the hospital infection management standard and the disinfection technical standard established by the national health function department, a medical institution executes 'one person one by one disinfection' on a humidification bottle used by an inhaler, and the humidification liquid is replaced once in 24 hours according to the aseptic operation technology, so that the bacteria carrying conditions of the humidification bottle and the humidification liquid are strictly controlled, the occurrence of iatrogenic cross infection in a hospital of an oxygen therapy patient is reduced, the medical cost is favorably reduced, the economic burden of the patient is lightened, the hospitalization time is shortened, and the medical institution becomes a problem that hospital infection managers and nursing staff pay more and more attention to.
In order to prevent cross infection in hospitals caused by humidification bottles, the humidification bottles used repeatedly in hospitals are generally treated by the following three disinfection methods and then reused: (1) the disinfection is carried out by soaking the disinfectant, the soaking treatment time is long, the efficiency is low, and the drying and the storage of the humidified bottle after the disinfection are inconvenient. (2) Ethylene oxide sterilization is expensive due to the adoption of special sterilization equipment, certain residues are left in the bottle after sterilization, and scale in the bottle is difficult to thoroughly remove, so that reuse is influenced. (3) The high-pressure sterilization is carried out by collecting and then uniformly sterilizing the materials by the central supply room, the process is long, the cost is high, the strength of the high polymer material of the sterilized humidification bottle is reduced, the potential safety hazard occurs, and the sterile storage period of the humidification bottle is still short.
Just because the humidification bottle is inconvenient to disinfect after being reused, the disposable humidification bottle filled with humidification liquid is produced by transportation. However, in the disposable humidification bottle sold in the market, a plurality of technical defects still exist:
(1) the cup cover is sealed by chemical glue, so that the potential safety hazard of environmental protection exists. The cup body and the cup cover made by the injection molding process form a disposable humidifying bottle, and in order to prevent repeated use, after humidifying liquid is filled, an air pipe and other accessories are arranged in the humidifying bottle, the cup body and the cup cover are fixedly connected through threads, and glue is adopted for bonding, sealing and curing. Not only the work efficiency is low, the cost is high, but also the chemical glue is not beneficial to the environmental protection and the safe use of patients.
In the patent application (application number is 201820055198.7, the name is a disposable oxygen humidifying bottle), although the technical scheme of adopting reverse sawtooth threaded connection is proposed, the defects of the technology can be solved, the humidifying bottle is used because of adopting an injection molding process, and in order to guarantee the pressure resistance of a cup body, the structure is complex, the used materials are more, the waste is obvious, and the product cost is increased.
(2) The bottle mouth is sealed by adopting the rotary bottle cap, so that the aseptic quality of the humidification liquid in the validity period is difficult to ensure. In the patent application (application number is 201520779963.6, the name is an oxygen uptake humidifying bottle), in order to ensure the leakproofness of humidifying bottle, guarantee the aseptic effect of humidifying liquid, disclose a solution, seal through setting up PET electrochemical aluminium sealing membrane in humidifying bottle bottleneck department, solved the not enough of above-mentioned technique. But neglects the influence of the air entering the bottle on the humidification liquid in the humidification liquid filling process. After the air with bacteria enters the humidification bottle, the humidification liquid is still polluted in the storage period. If the humidification liquid is filled and sterilized by radiation in the later period, the cost is high, the product cost is increased, and the production time is prolonged.
(3) Most disposable humidifying bottles are air inlet joint, air outlet joint and cup cover injection molding, the joint mouth adopts the seal cover to seal, because of the influence of the transport or storage environment in the transportation, the sealing performance variation or the drop of seal cover leads to the germ to get into the bottle from the joint mouth, has the emergence of influence humidifying liquid quality accident occasionally. The Chinese patent name is a solution of an oxygen humidification bottle (application number is 201010615897.0), although the problems can be solved well, the structure is complex, the material consumption is more, the installation is time-consuming, the cost is high, and the market competitiveness of the product is lacked.
At present, no report and research on a medical disposable oxygen humidification bottle which is manufactured by adopting an injection (plastic) blowing (plastic) process and is filled with medical nitrogen and is pre-filled with sterile water is found in commercially available products and research documents, and no medical disposable oxygen humidification bottle product which is pre-filled with sterile water and is prepared by adopting a buckle-free plug-in connector is found; and the humidifying bottle is generally connected with the oxygen inhalator through a valve body, the air pipe and the oxygen inhalator need to be ensured to be hermetically communicated, the general operation is troublesome, and meanwhile, the humidifying bottle is easy to cause humidifying liquid pollution in the operation process.
