Description
Technical field
This utility model is related to a kind of medical injection apparatus for irrigating, and more particularly to a kind of medium atomization formula is clear
Wound device.
Background technology
Medical injection apparatus are also referred to as purging system in medical field.Purging system is widely used between surgery average of operation periods
Cleaning tissue regions.Herein, normal saline solution and Ringer's mixture are typically used as flushing liquid.Using the purging system,
Spray-cone or jetting stream are produced with flushing liquid, and makes which impact tissue regions to be cleaned and these tissue regions are applied
Plus mechanical cleaning performance.
Traditional debridement is intended to clean, sterilize the wound for polluting, and removes foreign body, cuts off slough, be allowed to be changed into clear
Clean wound, so that be conducive to wound healing.Clinical debridement mode more typical at present be with saline or abluent being vortexed or
Wound surface is cleaned in purging method.Wound washing typically provides continuing or pulse type liquid punching for basic, normal, high pressure with some equipment
Wash.Low-pressure developing result may be poor, and high pressure may damage normally activated tissue.Pulsed lavation is hydropathic
One kind, refers to and goes to rinse and clean wound with pressurization, pulsed liquid, finally by the slough fragment of wound and punching
Washing liquid is sucked.The shortcoming of these methods for clinically using at present includes that medicinal liquid consumption is big, to the zest of wound surface very
By force, patient has stronger pain.Meanwhile, in operation, also occur that wound wound surface cleans halfway phenomenon, shadow
Ring the healing effect of wound wound surface.
US20080319453Al disclose a kind of utilization high velocity air nozzle and pressurization fluid injector formed have scrape
The device of the aerosol of cleaning action, is clearly located in outside gas spout from fluid injector shown in its accompanying drawing 2-7 and description 0019
Section, fluid injector are connected with the liquid supply source of pressurization, also support that the outlet of fluid injector is arranged by device inventor intentionally
On the outside of gas nozzle.
Patent CN103418046A discloses a kind of medical spraying equipment, and its nozzle is according to industrial conventional venturi spray
The principle design of pipe, the negative pressure produced in liquid tube is voluntarily sucked.
Ideal conditionss for rinsing the medical spraying equipment needs of wound surface are main both ways：The air-flow of high speed as far as possible
Atomized drop with appropriate diameter.Air velocity height can increase the kinetic energy entrained by drop, strengthen scraping effect.Meticulous liquid
Because be present larger viscous force in drop, it is intended to swept along by air-flow between stoke effect and gas, major part can not reach clear
Clean wound surface.Viscous force between excessive drop and gas is less, inertia is larger, is difficult to be accelerated to higher speed by air-flow
Degree, does not reach the purpose of cleaning wound surface yet.Practice have shown that the about little drop between 10-50 microns of diameter have most strong clear
Clean effect.
Technical scheme disclosed in US20080319453Al needs to provide fluid pressure, improves the complexity of device.
Liquid voluntarily can be sucked by technical scheme disclosed in CN103418046A, and can provide the air-flow of more high speed, but
Liquid can occur overatomize in venturi nozzle so that drop is meticulous, reduce and strike off cleaning action to slough.
In addition venturi nozzle sprays air-flow and drop more disperses, and is also unfavorable for that cleaning action is struck off in raising.
Similar to CN103418046A, CN2560364Y discloses a kind of medical washer, and its liquid outlet is also disposed at
Near the position of gas-liquid injection mouth and gas-liquid injection mouth is directed in gas spray chamber.The technical scheme can realize liquid negative pressure certainly
The problem of overatomize is equally existed when after suction, but liquid and gas mixing by narrow gas-liquid injection mouth.
Content of the invention
In view of the shortcoming of above-mentioned prior art, a kind of medium atomization formula wound-cleaning device of this utility model offer, it is possible to use
Stress-free fluid supply forms the high speed atomisation air-flow of appropriate droplet size distribution, so as to using when reach more preferably wound surface
Cleaning effect.
Technical scheme is as follows：
A kind of medium atomization formula wound-cleaning device, including medium atomization shower nozzle, gas medium pipeline and liquid medium pipeline, institute
Give an account of
Connection, the liquid medium passage and liquid medium pipeline connection, the gas medium passage and liquid medium passage coaxially set
Put, and liquid medium passage is located at gas medium channel interior, the outlet of the gas medium passage and liquid medium passage
Outlet is concordant.
In said structure, gas medium passage and liquid medium passage are coaxially disposed, and liquid medium passage is located at gas
Inside medium channel, for the outlet of the gas medium passage meaning concordant with the outlet of liquid medium passage is, periphery is high
Fast air-flow produces enough negative pressure so that the liquid in liquid medium passage is with sufficiently large in liquid medium channel exit
Flow velocity sprays, and is unlikely to again to be fractured into meticulous drop.Droplet distribution in the gas flow between position, also be more conducive to improve cleaning make
With.Apparatus structure is simple, and liquid is automatically drawn into, without the need for pressure apparatus.It is easy to make disposable product, can be prevented effectively from institute
Cross infection.
The beneficial effects of the utility model are, after employing the medium atomization formula wound-cleaning device of said structure, using liquid
Body atomized spray, to wound surface atomization cleaning, on the premise of cleaning performance is ensured, greatly reduces the usage amount of medicinal liquid, mitigates
High voltage stimulus of the medicinal liquid to wound surface, the medium atomization formula wound-cleaning device of said structure have simple structure, easy to use and real
Effect, and rinse well thoroughly, can wash to multiple, substantially, during use, the comfort level of patient is improved clinical debridement effect.
