Description

A kind of medical smoking machine

Technical field

The invention belongs to medical smoking machine technology.

Background technology

Medical smoking machine belongs to the environmental protection equipment in operating room, for removing the smog in operation.Using laser, electric knife or During ultrasonic operation, substantial amounts of smog can be produced, in these smog, contain substantial amounts of harmful chemical, flue dust, oil droplet and tool Activated virom crosome, all has great harm to patient and medical worker.In order to reduce these harm, people have invented doctor With smoking machine and correlation technique, document cn90200112.4, cn91226202.8, cn201020600891.1, Cn201120374229.3, cn201020117116.0 have integrally made some descriptions to smoking machine, and document cn91226202.8, Cn201110459659, cn201120488667.2, cn201220421687.2 are just for the improvement of knife head for surgical.Above-mentioned this All with improving, relevant discussion is not provided to the technical requirements of smoking machine most important part filter element in a little documents.

The basic structure of existing medical smoking machine is as shown in Figure 1.In Fig. 1,1 is Smoking pipe, and 2 is pretreatment unit, and 3 is filter Core, 4 is dust absorption fan, and 5 is control system.Filter element 3 is entered, through filter element 3 mistake after the preprocessed device of smog 2 that Smoking pipe absorbs The gas of filter is extracted out by dust absorption fan 4, and 5 is control system, for controlling the opening, stop of blower fan, air quantity and the inspection to gas componant Survey etc..

Because medical smoking machine is used for removing poisonous smog in operation, therefore, it is necessary to meet following several requirements: can have Toxic gas and various microgranule (good filtration effect), noise in effect filter smoke are low, suction is big, small volume (is easily installed By operating-table).

In medical smoking machine, filter element is core component, directly affects filter effect, simultaneously for the noise reducing smoking machine Volume is also extremely important with reducing.

Content of the invention

The present invention in view of the shortcomings of the prior art, proposes a kind of medical smoking machine, provides medical smoking machine filter element skill Art parameter and two kinds of filter cartridge constructions, can meet be issued in limited volume poisonous in the more preferable filter smoke than prior art Gas and the effect of various microgranule.

Technical scheme is as follows:

A kind of medical smoking machine, it is made up of Smoking pipe, pretreatment unit, filter element, dust absorption fan and control system.This The bright technical parameter providing filter material in medical smoking machine filter element: the effective area 10000cm of filter material²≥s≥800cm², effective body Long-pending 12000cm³≥v≥2500cm³.The acquirement of this parameter is according to analysis below and experiment:

Fig. 2 is filter material schematic diagram in filter element.Gas after Smoking pipe and pretreatment unit even into filter element, if its air-flow Density is v, and filter material effective admission surface area is s₁, area of effectively giving vent to anger is s₂, average effective area

s = \frac{s_{1} + s_{2}}{2}

Filter material thickness is d, then the flow m=s v of gas, the volume v=s d of filter material

In order to obtain optimal filter material parameter, the present invention has made substantial amounts of test, and concrete grammar is as follows: uses co₂Laser or electricity Smog in the smoke simulation operation process that the fresh Corii Sus domestica of knife calcination produces, the parameter changing filter material is filter material species, filter material Average effective area s, volume v of filter material, the thickness d of filter material, adsorbed with the smoking head of Smoking pipe one end be aligned smog, Observe the noise situation of change of its Scavenging activity to smog abnormal flavour and smoking machine, main result is as follows:

In the existing filter material that can obtain in a large number, optimal with activated carbon and its product.

In the case that noise meets the requirements, with activated carbon and its product as filter material filter element, right under different parameters The Scavenging activity of smog is as follows:

According to test with analyze further, in order to guarantee active adsorption perform the operation in smog and make smoking machine noise, body Amass in the range of operation allows, in the filter element of the present invention, filter material parameter is:

Filter material effective area 10000cm²≥s≥800cm²

Effective volume 12000cm of filter material³≥v≥2500cm³

In the case of identical filter material volume, effective area s is bigger, and that is, thickness d is less, then resistance is less, and noise is lower.

Require to adapt to different operations further, the filter material parameter of the present invention can be limited in values below further:

The effective area 2000cm of filter material²≥s≥800cm²

The effective area 3500cm of filter material³≥v≥2500cm³.

According to above parameter, the present invention provides following preferred filter cartridge construction.Described filter element include inner core, gas passage and Shell；Described gas passage is provided with n equidistant air inlet, and n inner core is separately mounted on n air inlet, all interior Core shell covers, and constitutes a filter element；There is total air inlet on described shell, gas passage has total air vent, flue gas is through total Air inlet enters in housing, filters through each inner core, is collected by gas passage, discharge flue gas from total air vent.

The preferably following two version of above-mentioned inner core:

Described inner core be two-sided inner core, including in core crab and filter material；Interior core crab is by upper and lower two pieces of parallel transverse slats, centres Two pieces of parallel relative risers and in front and back two blocks of side plates are constituted, and steam vent or air discharge duct are distributed with two pieces of middle risers；? On lower cross plate, there is bar shaped air vent the position between corresponding two exhaustion plates, overlaps with the air inlet on gas passage；Filter material is to live Property charcoal and its product, be close to the outside of middle two pieces of risers, form two-sided planar symmetrical structure.

Described inner core be tubular core, including in core crab and filter material；Interior core crab by pipe and its two ends install upper Base plate is constituted with lower shoe, and upper plate seals, and lower shoe has a circular hole as the air inlet weight on steam vent, with gas passage Close；Some apertures or little bar-shaped trough are distributed with tube wall；Filter material is activated carbon and its product, is close to the outside of pipe.

Using above technical scheme, require because the filter material of filter element meets specific parameter designing, the structure of filter element can Meet the increase of filter material effective area, therefore, it is possible to reach under conditions of meeting surgical apparatuses volume requirement, obtain optimum Smoke filtration clean-up effect.
