Description
Technical field
The present invention relates to a kind of gas-filtering device, particularly a kind of operation smoke filter.
Background technology
In recent years, laparoscopic surgery is more and more general in medical clinical practice.In laparoscopic surgery, while utilizing the equipment such as ultrasound knife, electric knife and laser to cut tissue, be and utilize heat to cause carbonized volatilization, can form operation smoke.Patient, for guaranteeing that surgical field of view is clear, needs repeatedly or opens all the time puncture casing air bleeding valve, discharges a large amount of operation smokes.Confirm after deliberation, operation smoke is mainly by water vapour and cell debris granulometric composition, granule generally by chemical substance, blood and fragment of tissue, live virus, competent cell and can induced mutation etc. material composition form.Wherein, the chemical composition meriting attention comprises polycyclic aromatic hydrocarbon, acrylonitrile and Blausure (German) etc., is colourless poisonous chemical composition, the long-term probability that human body is had cytotoxicity, genotoxicity, causes chromosome breakage and bring out sudden change of taking in.The pathogen simultaneously containing in operation smoke can infect corresponding disease as human papillomavirus, hepatitis B virus or Epstein-Barr virus.Confirm at present, operation smoke can pass through skin, lung, mucosa and eyes and take in the body of medical worker in operating room, long-term chronic is taken in can cause mucocutaneous, upper respiratory tract irritation, simultaneously with carcinogenic, teratogenesis, the serious consequences such as antibacterial, viral infection.
In addition, need to continue injecting carbon dioxide gas and maintain pneumoperitoneum in laparoscopic surgery, during open air valve, great amount of carbon dioxide follows operation smoke to discharge.In operating room enclosed environment, the carbon dioxide pollution meeting of air middle and high concentration causes operation room work personnel to occur the symptoms such as headache, tinnitus, blood pressure increase, rapid breathing, absent minded, limbs fatigue.
The operation smoke that laparoscopic surgery is discharged and carbon dioxide are mainly collected at operating-table top, and the medical personnel that very easily performed the operation take in.The measures such as the clean by laminar flow of clinical configuration at present,, smog attraction and monolayer mask can not protect medical personnel to avoid the harm of operation smoke and carbon dioxide.Meanwhile, the surgical environments of operation smoke pollution also can cause harmful effect to patient health.Because the operation smoke discharging in laparoscopic surgery and carbon dioxide easily cause employment injuries; long-term absorption can cause serious threat to operating room medical personnel; therefore be badly in need of the discharge that effective equipment reduces and eliminate operation smoke and carbon dioxide; in operating room, build non smoke contaminated operation environment, protection medical personnel and patient's physical and mental health.
Summary of the invention
The object of the invention is to for the problems referred to above, provide a kind of operation smoke filter of easy to use, economical and efficient, for building non smoke contaminated operation environment.
The object of the present invention is achieved like this:
An operation smoke filter, is characterized in that: comprise the closure casing with entrance and exit; Described entrance and exit is located at respectively on two opposite faces parallel to each other of closure casing; In described closure casing, from entrance to outlet, be followed successively by harmful gas filter chamber and carbon dioxide absorption chamber; Air inlet pipe and escape pipe extend respectively outward from housing in the entrance and exit place of described closure casing.
Wherein; In the outlet of described closure casing, be covered with the first porous plate, its inside is provided with second porous plate parallel with the first porous plate, and described the second porous plate is separated into harmful gas filter chamber and carbon dioxide absorption chamber by closure casing.
Wherein, in described harmful gas filter chamber, be equidistantly provided with the some and parallel plane glass fiber filter paper in entrance place.
Wherein, be uniformly-spaced provided with the baffle plate of some symmetries on the inwall of described closure casing along entrance to the second porous plate direction, described glass fiber filter paper is fixed in harmful gas filter chamber by baffle plate.
Wherein, medical calcium Calx has been filled in described carbon dioxide absorption chamber.
Wherein, described closure casing is connected and forms with the drain pan that is provided with harmful gas filter chamber and carbon dioxide absorption chamber by lid.
Wherein, described drain pan and lid are connected to form closure casing by sealing gasket.
Wherein, described drain pan and lid are by the formation closure casing that is connected of external screw thread and female thread.
Beneficial effect of the present invention:
1) compact conformation, easy to use, simple to operate, during use, need only and directly filter air inlet pipe be connected on laparoscope puncture casing pore and open air valve.
2) economical and efficient, manufactures cost low, can effectively remove laparoscopic surgery simultaneously and produce deleterious particle and the carbon dioxide in flue gas.
3) be easy to reclaim destruction, meet Disposable Aseptic Medical Instruments administrative provisions.

Wherein: 1-closure casing, 11-entrance, 12-outlet, 13-air inlet pipe, 14-escape pipe, 15-baffle plate, 2-harmful gas filter chamber .21-glass fiber filter paper, 3-carbon dioxide absorption chamber, 4-the first porous plate, 5-the second porous plate.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, further set forth the present invention.
As shown in Figure 2, a kind of operation smoke filter, comprises the closure casing 1 with entrance 11 and outlet 12; Entrance 11 and outlet 12 are located at respectively on two opposite faces parallel to each other of closure casing 1; In closure casing 1, from entrance 11 to outlet 12, be followed successively by harmful gas filter chamber 2 and carbon dioxide absorption chamber 3; Air inlet pipe 13 and escape pipe 14 extend respectively outward from housing in the entrance 11 of closure casing 1 and outlet 12 places.
In the outlet 12 of described closure casing 1, be covered with the first porous plate 4, its inside is provided with second porous plate 5, the second porous plates 5 parallel with the first porous plate 4 closure casing 1 is separated into harmful gas filter chamber 2 and carbon dioxide absorption chamber 3.
Described harmful gas filter chamber 2 is interior is equidistantly provided with some and the entrance 11 parallel plane glass fiber filter paper 21 in place.
On the inwall of described closure casing 1, along entrance 11 to second porous plate 5 directions, be uniformly-spaced provided with the baffle plate 15 of some symmetries, glass fiber filter paper 21 is fixed in harmful gas filter chamber 2 by baffle plate 15.
