Single-use combined humidification bottle system for medical oxygen inhalator

Abstract

The invention discloses a single-use combined humidification bottle system for a medical oxygen inhalator. The single-use combined humidification bottle system comprises a humidification bottle, an outer cup, an outer cup cover, a gas pipe bracket, a splicing connector, a gas pipe, a humidification core and a valve body, wherein the outer cup is arranged outside the humidification bottle; the outer cup cover is movably connected with the top of the outer cup; the valve body is movably connected onto a connecting column; the top of the splicing connector is tightly spliced onto a splicing partof the valve body; a gas inlet is formed in the middle of the valve body; a gas pipe splicing hole is formed in the middle of the splicing connector; the gas pipe bracket is mounted at the top of thehumidification bottle; a gas pipe locating sleeve is arranged in the middle of the gas pipe bracket; a gas outlet is formed in the valve body; the humidification core is mounted at the bottom of the gas pipe; the top of the gas pipe penetrates through the gas pipe locating sleeve; the bottom of the humidification core tightly pushes against the inner side of the bottom of the humidification bottle; when the humidification bottle is mounted, the bottom of the humidification bottle applies an upward driving force to the gas pipe to assist the gas pipe in being inserted into the splicing connector of the valve body; and the gas pipe locating sleeve plays a role of guiding vertical splicing movement of the gas pipe, so that assembly between the gas pipe and the valve body of the humidificationbottle can be achieved quickly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable combined 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 adsorption molecular sieve) contains only about ...

AI Technical Summary

Problems solved by technology

[0008] In order to prevent nosocomial iatrogenic cross-infection caused by humidification bottles, hospitals usually use the following three disinfection methods for reusable humidification bottles before reuse: (1) soaking in disinfectant for disinfection, long soaking time and low efficiency, It is inconvenient to dry and store the humidification bottle after disinfection

(2) Ethylene oxide sterilization, use more expensive special disinfection equipment for disinfection, there will be a certain amount of residue in the bottle after disinfection, it is difficult to completely remove the scale in the bottle, which will affect the 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

[0011] 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

[0012] (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

Therefore, the humidification bottle must be sterilized by radiation after pre-filling the humidification solution, which not only increases the cost of the product, but also increases the difficulty of quality control

[0013] (3) In most disposable humidification bottles, the air inlet joint, air outlet joint and cup cover are injection molded, and the joint mouth is sealed with a sealing sleeve. Due to the influence of handling or storage environment during transportation, the sealing performance of the sealing sleeve will change. Poor or falling off, causing germs to enter the bottle from the joint, and accidents affecting the quality of the humidification solution occur from time to time

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.

At present, reusable humidification bottles on the market are generally directly connected to the oxygen inhaler through the valve body. It is necessary to ensure that the trachea and the oxygen inhaler are airtight and connected. The operation process is relatively cumbersome, and it is easy to cause secondary pollution of the humidification liquid.
