Description

Fuming device

Technical Field

The utility model belongs to the technical field of medical equipment, a device field is related to, concretely relates to device that simulation operation smog took place and aassessment operation smog harm.

Background

Surgeons and medical personnel in the operating room are often exposed to smoke generated when using electrosurgical devices, an occupational hazard that is often overlooked. Surgical smoke has been shown to be mutagenic as cigarette smoke and has also been reported to provide evidence of its potential infectivity. Although the components and hazards of the surgical smoke are continuously researched and elaborated at home and abroad since 1981, and corresponding management policies and operation specifications are provided successively, investigation shows that medical workers are unclear in cognition on the source, hazards and protective measures of the surgical smoke so far, and self-protection consciousness is low. The popularization of protection knowledge and the implementation of protection measures are so difficult, and one important reason is that few researches specifically analyze the influence factors of the generation, dispersion and distribution of smoke and the removal efficiency.

Particulate contamination in operating rooms depends mainly on the procedure, the mode of ventilation, the personnel garment system and the working procedure. Precautions, namely, local exhaust ventilation (e.g., suction associated with a smoke pump, surgical knife) and personal protective equipment (e.g., protective mask), prevent and limit the inhalation and exposure of surgical smoke. But many investigations and studies have shown that conventional surgical masks and ventilation systems are inadequate to control this problem. The aspirator and the like are used as close to the air pollutant source as possible, and can provide effective smoke exhaust. However, due to the disturbance of the airflow, the smoking efficiency of the aspirator itself is negatively affected and may interfere with the surgical activity. Smoking pumps typically produce a loud noise when they reach an effective smoke rate, and are therefore rarely used, exposing medical personnel to high concentrations of smoke.

SUMMERY OF THE UTILITY MODEL

The utility model provides a smoke generating device to the above-mentioned problem for research operation smog is to the influence of human body.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a smoke generating device, the device includes the casing, casing upper portion be equipped with the mouth of giving out a cigarette, the lower part is equipped with the fresh air mouth, the left end of casing or right-hand member be equipped with spring propeller, be equipped with spring and moxa stick in the spring propeller.

The utility model discloses among the technical scheme: the smoke outlet is arranged above the burning moxa stick.

The utility model discloses among the technical scheme: the spring is movably connected with the moxa stick.

The utility model discloses among the technical scheme: and the input end of the fresh air port is sequentially connected with the pipeline type flowmeter and the low-noise air pump.

The utility model has the advantages that:

the utility model provides a smoke generating device for studying operation smog is to human influence, the research that the device can go on as follows:

(1) the influence factors of the initial smoke amount are explored. The self-control smoke generating device changes the fresh air flow rate input into the self-control smoke generating device by simulating the generation and the divergence of the operation smoke, and the initial smoke generating amount of the smoke generating device can be adjusted. By PM_2.5Monitoring PM in a field environment on-the-fly as an indicator_2.5The method is horizontal, the actual smoking condition in laparoscopic surgery and liver surgery is fitted with certain simulation, and good stability is achieved. The device can provide a research means for the clinical deep understanding of the spatial distribution of pollution in different operations, and can further provide a basis for matching different smoking protection measures for different operations.

(2) And comparing and analyzing the smoke concentration of monitoring points with different space-time distributions, and exploring factors influencing the space-time distribution. Establishing an operating room laminar flow environment simulation system based on literature research, investigating the maximum possible exposure position of medical personnel in the operation process, setting monitoring points in different directions according to the maximum possible exposure position, and comparing PM (particulate matter) in all directions₁₀、PM_2.5、PM_1.0And particle number levels in different particle size ranges, while monitoring and analyzing the gaseous pollutants (formaldehyde and TVOC). The relative position of the medical staff in the operation can be guided according to the pollution distribution condition so as to reduce the actual exposure.

(3) The influence factors of the smoke electrotome on the smoke removal efficiency are explored. The tube length, the tube caliber, the operation angle and the negative pressure gear of the smoke suction electric knife in the experiment are respectively changed, and the changes before and after smoking of each index are compared. Provides basis for clinically selecting the electrosurgical equipment which has high smoking efficiency and is suitable for use so as to reduce the possible smoke hazard in the actual operation.

Therefore the utility model provides a device can study the influence of the flue gas that produces in the operation process to the human body, can discuss the influence of different operating condition to the smoking efficiency of smoking electrotome to further can have certain reference meaning in the aspect of the research that the prevention doctor inhales the flue gas in the operation process.
