Description

SARS patients accepting oxygen inhalation exhalation collection virus device
Technical field
This utility model relates to a kind of a kind of SARS patients accepting oxygen inhalation exhalation collection virus device of clinical oxygen uptake medical treatment device, particularly respiratory infectious disease infection mitigation.
Background technology
Severe acute respiratory syndrome is a kind of new stronger disease of infectiousness, with infringement pulmonary, and causes that dyspnea is a feature, and the person accounts for 10% with respirator treatment, and needing in normal way, oxygen therapic patient accounts for about 50%.Respiratory tract is its topmost route of infection.Because former oxygen supply device designs at noninfectious.As: the nasal tube oxygen inhalation device, open mask oxygen-inspiration device, the nose cup inhalation device is open inhalation device.During the opening oxygen uptake, the patient expired virus of SARS is untreated and is discharged between the ward, is sucked respiratory tract by other people, is the major reason that causes high infection rate, also is the major reason that patient increases the heavy inhalation rate of its virus.
In order to solve other people high infection rate problem due to the SARS, Changchun has worked out through the respirator air vent and has collected patient expired virus, and the disinfectant device.Nanjing works out " SARS safety is isolated the room ".At present, Shang Weijian is to the appearance of open oxygen uptake exhalation collection virus device.
This utility model has absorbed Zhao Jiaxun, Zhang Jianmin, Wu Ji etc.Coaxial sky mixes Mapleson A/D compatible circuit.China's anesthesia science magazine, 1989; (3): the research in 137. pairs of anesthesia respiration loops, in conjunction with this problem, face shield is closed in utilization, two-tube two-way corrugated tubing, overlength exhaust tube, empty oxygen mixer, individual event air inlet flap valve, air storage bag and air compressor etc., the patient expired collection virus device of research SARS.
Summary of the invention
This utility model solves patient's SARS viral collection problem of breathing out when oxygen uptake: open oxygen uptake is become the oxygen uptake of closing property.The oxygen uptake of closing property need solve air-breathing road, separate on the expiration road, one-way flow, and airway resistance, problems such as exhalation collection virus provide a kind of SARS patients accepting oxygen inhalation exhalation collection virus device.
The concrete scheme that this utility model solves SARS patients accepting oxygen inhalation exhalation collection virus is to realize like this, end cover at tee T is connected with the expiration corrugated tubing, be communicated with the vacuum suction pipe in the pipe of expiration corrugated tubing, other end cover at tee T is connected with air-breathing corrugated tubing, the end of air-breathing corrugated tubing is communicated with free oxygen mixer, the oxygen supply pipe is inserted in the bottom of empty oxygen mixer, one side is provided with the fresh air import of band control valve, cover is connected with and closes face shield on the pipe of the top of tee T, and is fixed by fixing band and incidence.
This utility model is isolated from the outside the patient respiration road with closing face shield, by air-breathing corrugated tubing and expiration corrugated tubing, suction, expiration road is separated.Use the air fluid theory of mechanics, removed inspiratory valve traditional, widespread usage, use empty oxygen mixer, continue the negative pressure gravitation of the oxygen jet generation of oxygen supply formation in a small amount, mix the fresh mass air flow that forms with air and enter air-breathing corrugated tubing, and the generation continuous positive pressure, enter in the lung during patient inhales.In the expiration corrugated tubing, be communicated with the vacuum suction pipe, patient expired gas and spittle virus all can be sucked in the deferent, send into disinfector and carry out disinfection.If the vacuum suction pipe be inserted into the middle part in the expiration corrugated tubing and be communicated with pin, promptly semi-open property expiration corrugated tubing, the patients accepting oxygen inhalation viral better effects if of breathing out.
In addition, on the expiration corrugated tubing, increase air storage bag, can eliminate the airway resistance that causes, and place a plastic tube, utilize negative pressure suction force, patient expired gas and spittle virus are sucked in the filter sterilizer at overlength expiration corrugated tubing middle part.Form limited negative pressure in the expiration corrugated tubing, help the discharge of patient expired gas, its end is established a unidirectional air inlet flap valve, and when the pipe internal pressure was lower than ambient pressure, air can enter, and can not cause the lung atrophy.Closing property corrugated tubing adds the slow charging system of the volume formation respiratory tract of air storage bag, and the resistance when inhaling expiration to reduce has improved the oxygen uptake effect simultaneously.The people is in respiratory, and inspiratory/expiratory is 1: 1~1: 2, very reaches more than 1: 3.Open oxygen uptake only when air-breathing oxygen supply just can be inhaled into, and the time institute's oxygen supply of exhaling enters the space, accounts for 1/2~2/3 of oxygen-supplying amount.This device deposits oxygen in air-breathing corrugated tubing, tee T when exhaling, when air-breathing, oxygen and the storage oxygen of supplying with is sucked in the lung, and oxygen absorbed is increased.In addition as requested, close the sky oxygen mixer, improve concentration of oxygen inhalation.
The coherent detection situation of SARS patients accepting oxygen inhalation exhalation collection virus device is as follows:
Resistance between tee T, air-breathing and expiration corrugated tubing end: 0.46~0.6cmH 2O/0.5L/S meets the pertinent regulations of international standard: adult:<5cmH 2O/0.5L/S, child<5cmH 2O/0.5L/S.
In catcher, when using empty oxygen mixer, the relation of oxygen flow and fresh empty oxygen gas mixture flow sees Table 1.The adult: the per minute ventilation is about 10L~12L under the tranquility.Therefore, oxygen flow 2.5L~3.0L/min, fresh gas flow 14L~16L/min can satisfy the Human Physiology needs.The child is cut down according to the circumstance: 1.5L~2.0L/min gets final product.
Table 1
Oxygen flow Fresh gas flow
1.0L 1.5±0.9mm(1L~3L/min)
1.5L 5.8±0.8mm(5L~7L/min)
2.0L 10.1±0.5mm(9L~11L/min)
2.5L 14.8±0.6mm(14L~16L/min)
In catcher, when using empty oxygen mixer, the relation of oxygen flow and fresh air mixed airflow oxygen concentration sees the following form:
Oxygen flow Fresh gas flow
1.0L 68.8±12.1%(62%~74%)
1.5L 44.6±3.1%(42%~48%)
2.0L 38.4±2.8%(36%~40%)
2.5L 34.6±2.2%(32%~36%)
During routine oxygen supply 2.5L/min, oxygen concentration is about 32%~36% (oxygen concentration is 21% in the air), meets safety requirements.
Human trial is observed as follows: experimenter 5 people, be the male, and 54~58 years old age, body weight 62~71kg, vitals do not have organic disease.At blood pressure, pulse, blood oxygen saturation, monitor monitoring under test and observe.Oxygen flow: 3L/min, empty oxygen mixer is in open state, about vacuum suction capacity 20L/min, observes continuously 30~60 minutes.The result: to blood pressure, pulse frequency does not have influence, can improve blood oxygen saturation 2%~4%.No air flue resistance, patient comfort, reaction is good.
