Disposable humidification bottle system for medical oxygen inhalator

Abstract

The invention discloses a disposable humidification bottle system for a medical oxygen inhalator. The disposable humidification bottle system comprises a humidification bottle body, an air pipe supporting bracket, an inserting and connecting head, an air pipe, a humidifying core and a valve body, wherein a bottleneck is arranged at the top of the humidification bottle body; the valve body is in sealing connection with the bottleneck; the top of the inserting and connecting head is tightly connected to the inserting and connecting part of the valve body in an inserting manner; an air inlet is formed in the middle part of the valve body; an air pipe inserting and connecting hole is formed in the middle part of the inserting and connecting head; a U-shaped air pipe supporting bracket is arranged at the top of the humidification bottle body; an air pipe positioning sleeve is arranged at the middle part of the air pipe supporting bracket; an air hole is formed in the air pipe supporting bracket; an air outlet is formed in the valve body; the humidifying core is arranged at the bottom of an air pipe; the top of the air pipe penetrates through the air pipe positioning sleeve and is in sealing connection to the inner part of the air pipe inserting and connecting hole in an inserting manner; and the bottom of the humidifying core is tightly propped with the inner side of the bottom of the humidification bottle body. When the humidification bottle body is connected with the valve body, the bottom of the inner side of the humidification bottle body can apply upward thrust to the air pipe; under the vertical guiding effect of the air pipe positioning sleeve, the air pipe is automatically inserted in the inserting and connecting head of the valve body, so that the combined connection of the humidification bottle body and the valve body is quickly realized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable humidification bottle system for a medical oxygen inhaler. Background technique [0002] The medical oxygen inhaler (hereinafter referred to as the inhaler) is a basic oxygen supply device commonly used in medical institutions. It provides emergency oxygen supply and comfortable oxygen therapy by providing humidified oxygen to patients. The inhaler is mainly composed of two parts: a flow meter with adjustable oxygen flow rate and a humidification bottle filled with humidification liquid. The flow meter can be a buoy type oxygen flow meter or a digital oxygen flow meter. The mandatory automatic pressure relief device for inhalers can be installed on the flow meter or on the humidification bottle. [0003] Due to the preparation process, medical oxygen (whether it is liquid oxygen or medical oxygen prepared by molecular sieves) contains only about 10% water, which ca...

AI Technical Summary

Problems solved by technology

[0009] In order to prevent nosocomial cross-infection caused by humidification bottles, hospitals usually use the following three disinfection methods for reusable humidification bottles before reuse: (1) Disinfectant soaking disinfection, long soaking treatment time, low efficiency, wet after disinfection Inconvenient for bottle drying and storage

(2) For ethylene oxide sterilization, it is more expensive to use special disinfection equipment. After disinfection, there will be a certain amount of residue in the bottle, and it is difficult to completely remove the scale in the bottle, which will affect its reuse.

(3) High-pressure sterilization must be collected by the central supply room and then sterilized in a unified manner. The process is long and the cost is high. The strength of the polymer material of the sterilized humidification bottle is reduced, and there are potential safety hazards in use, and the aseptic storage period of the humidification bottle is still valid. shorter

Not only low work efficiency and high cost, but also chemical glue is not conducive to environmental protection and safe use of patients

[0012] In the patent application (the application number is 201820055198.7, the name is a disposable oxygen humidification bottle), a technical scheme of reverse sawtooth thread connection is proposed to solve the shortcomings of the above technology, but the humidification bottle used is due to the injection molding process. In order to ensure the pressure resistance and sealing requirements of the cup body, the structure is complicated, more materials are used, and the waste is obvious, which increases the product cost

[0013] (2) It is difficult to ensure the aseptic quality of the humidification solution within the validity period by using a rotary bottle cap to seal the bottle mouth

However, the influence of the air entering the bottle on the humidification liquid during filling of the humidification liquid is ignored

After the bacteria-carrying air enters the humidification bottle, it will still pollute the humidification liquid during the storage period

If radiation sterilization is used in the later stage of filling the humidified liquid, it will not only increase the cost of the product, but also prolong the production time

[0014] (3) Most disposable humidification bottles are injection-molded with inlet joints, outlet joints and cup lids, and the joints are sealed with sealing sleeves. Due to the influence of handling or storage environment during transportation, the sealing performance of the sealing sleeves deteriorates Or fall off, causing germs to enter the bottle from the joint, and accidents that affect the quality of the humidification solution sometimes occur

The Chinese patent name is the solution of the oxygen humidification bottle (application number 201010615897.0), although it can solve this kind of problem better, but the structure is complicated, the material is more, the installation is time-consuming, the cost is high, and the product lacks market competitiveness.

[0015] At present, there are no reports and researches on commercially available products and research literature on medical disposable oxygen humidification bottles made by injection (molding) blowing (molding) technology and filled with medical nitrogen gas and prepacked with sterile water. The medical disposable oxygen humidification bottle product pre-filled with sterile water with a snap-in plug-in connector; and the humidification bottle is generally connected to the oxygen inhaler through the valve body, and it is necessary to ensure that the trachea and the oxygen inhaler are airtightly connected. The operation is more troublesome, and at the same time, it is easy to cause the pollution of the humidification fluid during the operation
