Abstract
The invention discloses a kind of respirator condensate water counterflow prevention device, including three-way connector, filtration members and the drying bottle of built-in desiccant, filtration members is placed in three-way connector, and the first port of three-way connector connects drying bottle, its second port and the 3rd port and connects respirator trachea；Filtration members is in the shape of falling π, and including horizontal filter screen filter screens longitudinal with two be vertically installed on horizontal drainage screen, horizontal filter screen is positioned at the first port of three-way connector, and two longitudinal filter screens lay respectively at the second port and the 3rd port of three-way connector；Filtration members is prepared by having absorptive material.The present invention can adsorb the steam in respirator trachea and established condensed water voluntarily, while alleviating the workload of medical personnel, it can also be ensured that the effect that condensate water-proof flows backwards.
Description
Technical field
The invention belongs to technical field of medical instruments, particularly relate to a kind of respirator condensate water counterflow prevention device.
Background technology
Respirator is the widely used a kind of medical apparatus and instruments of hospital.Can form condensed water during Use of respirator in pipeline, this is owing to during patient respiratory, the gas of exhalation forms in the condensation of catching a cold of breathing machine pipeline endogenous cause of ill.If condensed water processes not in time, because gathering and then may flow backwards.If refluence condensed water is inhaled by a patient, then can cause infection, serious also can be lethal.
At present, the way preventing condensed water from flowing backwards has employing to install condensation water bottle additional in breathing machine pipeline least significant end, for collecting the condensed water of condensation；The most also breathing machine pipeline is suitably heated, to reduce the difference of gas in pipelines temperature and room temperature, reduce the condensation water quantity formed.Although these measures can reduce the condensed water of formation to a certain extent, thus reduces the possibility occurring condensed water to flow backwards, but the effect preventing condensed water from flowing backwards is the most limited, and the measure heating breathing machine pipeline adds the workload of medical personnel.
Summary of the invention
The deficiency existed for prior art, the invention provides a kind of respirator condensate water counterflow prevention device more excellent without medical personnel's operation and condensed water anti-backflow effect.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that:
Respirator condensate water counterflow prevention device, including:
Three-way connector, filtration members and the drying bottle of built-in desiccant, filtration members is placed in three-way connector, and the first port of three-way connector connects drying bottle, its second port and the 3rd port and connects respirator trachea；Filtration members is in the shape of falling π, and including horizontal filter screen filter screens longitudinal with two be vertically installed on horizontal filter screen, horizontal filter screen is positioned at the first port of three-way connector, and two longitudinal filter screens lay respectively at the second port and the 3rd port of three-way connector；Filtration members is prepared by having absorptive material.
Above-mentioned three-way connector uses medical plastic to make, but has no special requirements the non-toxic medical plastic hardness used.
Above-mentioned filtration members has relatively strong absorptive and filter opening is distributed, concretely sponge.
Above-mentioned desiccant is activated carbon, and activated carbon particle size to be ensured is not less than filtration members filter opening aperture, to avoid activated carbon to be leak in three-way connector by filtration members.
Above-mentioned three-way connector is the most removably connected with respirator trachea, drying bottle, and engagement thread specifically can be used to be attached.
Compared to the prior art, present invention produces following beneficial effect:
1, only installing apparatus of the present invention with on respirator trachea, filtration members can adsorb the steam in respirator trachea and established condensed water voluntarily, simple to operate, can substantially alleviate the workload of medical personnel.
2, by drying bottle dry filter part, thus filtration members absorption steam and the ability of condensed water can be ensured, then ensure that the condensed water anti-backflow effect of apparatus of the present invention.
3, use flexibly, one or more apparatus of the present invention can be installed on respirator trachea additional according to actual needs, to reach more preferable condensed water anti-backflow effect.
Accompanying drawing explanation
Fig. 1 is the concrete structure schematic diagram of the present invention；
Fig. 2 is the concrete structure schematic diagram of filtration members of the present invention.
In figure, 1 three-way connector, 2 filtration members, the horizontal filter screen of 2-1,2-2 longitudinal direction filter screen, 3 drying bottles, 4 respirator tracheas.
Detailed description of the invention
The detailed description of the invention of the present invention is further illustrated below in conjunction with accompanying drawing.
The present invention includes three-way connector 1, filtration members 2 and drying bottle 3, and filtration members 2 is placed in three-way connector 1；First port of three-way connector 1 connects drying bottle 3 bottleneck, its second port and the 3rd two-port and connects respirator trachea 4.Filtration members 2, in the shape of falling π, is all vertically installed on horizontal filter screen 2-1 by bonding way including the longitudinal filter screen 2-2 of a horizontal filter screen 2-1 and two, two longitudinal filter screen 2-2.Laterally filter screen 2-1 is positioned at the first port of three-way connector 1, and two longitudinal filter screen 2-2 lay respectively at the second port and the 3rd port of three-way connector 1.
Three-way connector 1 uses non-toxic medical plastic to make, and has no special requirements the non-toxic medical plastic hardness used.Filtration members is bibulous thin matter non-toxic material, and fine and closely woven filter opening, such as sponge are distributed.Drying bottle 3 is built with desiccant, such as, and activated carbon, but desiccant particle diameter to be controlled makes it can not spill from the filter opening being distributed in filtration members.Three-way connector 1 is removably connected with respirator trachea and drying bottle, such as, thread connecting mode can be used to be attached.
Work process and the principle of the present invention are as follows:
During use, installing the present invention according to respirator air tubing length additional in suitable position, two ports that respirator trachea is removably not connected with drying bottle with three-way connector are connected.Filtration members can not affect respirator trachea unimpeded in the case of adsorb the steam in respirator tracheal strips gas.The condensed water formed for respirator tracheal strips, when it flows through three-way connector, can be absorbed rapidly by filtration members.Due to capillarity, in drying bottle, filtration members can be dried by desiccant, thereby may be ensured that the filtration members assimilation effect to tracheal strips condensed water.Filtration members is while absorption condensation water, and desiccant in drying bottle also can be played barrier effect by its horizontal filter screen, prevents desiccant from leaking in respirator three-way connector.
According to actual needs, one or more apparatus of the present invention can be installed on respirator trachea additional, to reach more preferable condensed water anti-backflow effect.
