Abstract
The utility model relates to a medical waste gas eliminating system for an anesthesia machine and a respirator. The system comprises a collecting pipe of the waste gas and a negative-pressure suction joint, wherein the collecting pipe of the waste gas and the negative-pressure suction joint are respectively connected with two communicated interfaces of a valve body; the valve body is provided with a passage way in a shape like the Chinese character 'gan'; the interface which is opposite to the collecting pipe of waste gas is connected with a buffering bag of the waste gas; the other opposite interfaces are respectively provided with a negative-pressure safety valve and a gas overflow valve. The utility model reasonably solves the conflict of the intermittent discharge and the continuous negative pressure of the respirator or the anesthesia machine, and ensures waste gas treatment to not influence the normal work of the respirator or the anesthesia machine. After the utility model is used, purifying quality of the indoor environment can be protected better and influences caused by the overflow of the various waste gas to the health of doctors and patients are avoided.
Description
Technical field
This utility model relates to a kind of medical waste scavenging system, especially a kind of medical waste scavenging system that is applicable to anesthetic machine, respirator.
Background technology
For a long time, the air pollution in specific medical place is high in the hospital, particularly operating room and all kinds of intensive care unit(ICU), because of the frequent life-time service of anesthetic machine, respirator, very easy by all kinds of waste gas of anesthesia and contain malignant bacteria and virus respirator treatment waste gas cause room air pollution.
Understand according to the applicant, available clinically at present product only has " anesthetics waste gas absorber to remove ".This product essence is the adsorbent equipment that includes active carbon, and its absorbability is limited, only can carry out passive absorption to the waste gas of anesthesia that contains volatile anesthetic; As be connected in the operate as normal that respirator then not only directly influences respirator, and to respirator discharge contain bacterium gas and other waste gas like water off a duck's back.
The utility model content
The purpose of this utility model is: at the shortcoming of above prior art existence, on the basis of original " capacity buffer-type anesthetic machine/respirator waste scavenging system ", propose a kind of volume valve control formula anesthetic machine/respirator waste scavenging system small and exquisite, easy to use, this system should be to the not influence of operate as normal of respirator/anesthetic machine.
In order to reach above purpose, valve control formula anesthetic machine of the present utility model/respirator waste scavenging system comprises gas sampling pipe and vacuum suction joint, described gas sampling pipe and vacuum suction joint connect the two intercommunicating interface of valve body respectively, described valve body is shaped on and is " doing " font path, the interface tipping waste gas impact bag that described gas sampling pipe is relative, biphase docking port is equipped with negative pressure relief valve and overflow valve respectively in addition.
During use, the gas sampling pipe on the valve body connects the air vent of respirator/anesthetic machine, and the vacuum suction interface is connected to the central suction system or other can produce the negative pressure device of continuous negative pressure suction.Because respirator/anesthetic machine is discharged medical waste gas according to the intermittent discharging of respiratory rhythm, the negative pressure that central suction produced then is continuously.Therefore, when respirator/anesthetic machine not when discharging waste gas or discharge amount of exhaust gas lower (being in expiratory phase), the waste gas impact bag subsides and plays cushioning effect, can absorb the room air that sucks by negative pressure relief valve this moment, and the gas capacity that sucks by negative pressure relief valve is enough, and the inspiratory phase pressure of the respirator/anesthetic machine operate as normal that therefore can not exert an influence changes (promptly can not produce the inspiratory phase negative pressure); When respirator/anesthetic machine discharging waste gas (being in expiration phase), abrupt release go out near or be slightly less than the gas flow of tidal volume, at first directly be discharged in the waste gas impact bag by connecting pipe, absorbed by negative pressure again, since the effect of impact bag, the exhaust resistance and the end expiratory positive pressure of the respirator/anesthetic machine operate as normal that also can not exert an influence.
This shows that this utility model has rationally solved the contradiction of the intermittent discharging of respirator/anesthetic machine with continuous negative pressure, has guaranteed that exhaust-gas treatment does not influence the operate as normal of respirator/anesthetic machine.After the use, can protect the depuration quality of indoor environment better, avoid various waste gas to overflow the hospitalized patients health affected.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Among the figure: 1, vacuum suction joint 2, valve body 3, gas sampling pipe 4, fairlead 5, overflow valve epithelium 6, overflow valve saddle 7, negative pressure relief valve epithelium 8, negative pressure relief valve saddle 9, waste gas impact bag 10, impact bag outer casing tube body
The specific embodiment
The valve control formula anesthetic machine/respirator waste scavenging system of present embodiment is shaped on the path that is " doing " font as depicted in figs. 1 and 2 on the valve body 2, form the interface of five intercommunications.Wherein, the interface of an end connects vacuum suction joint 1, two relative interface and connects gas sampling pipe 3 and waste gas impact bag 9 respectively, directly enters impact bag for the ease of waste gas, and the fairlead 4 that leads to waste gas impact bag 9 is housed at gas sampling pipe 3 interfaces.The waste gas impact bag 9 outer buffer air bag outer casing tube bodies 10 that are equipped with.Buffer air bag outer casing tube body 10 tops have steam vent.Like this, in waste gas impact bag inflation or when subsiding, not can and outer casing tube body 10 between produce pressure and change.Biphase docking port other on the valve body 2 is equipped with negative pressure relief valve and overflow valve respectively, and negative pressure relief valve and overflow valve are made of overflow valve epithelium 5 that is installed in overflow valve saddle 6 centers and the negative pressure relief valve epithelium 7 that is installed in negative pressure relief valve saddle 8 centers respectively.
During use, the gas sampling pipe 3 on the valve body 2 connects the air vent of respirator or anesthetic machine, and vacuum suction joint 1 is connected to the central suction system by connecting tube.When respirator or anesthetic machine when discharging waste gas or discharge amount of exhaust gas are not low, waste gas impact bag 9 subsides, and plays cushioning effect, can absorb the room air that sucks by negative pressure relief valve 7 this moment; When respirator or anesthetic machine discharging waste gas, waste gas directly enters in the waste gas impact bag 9, absorbed by negative pressure again, because the effect of impact bag 9, the exhaust resistance and the end expiratory positive pressure of respirator or the anesthetic machine operate as normal of also can not exerting an influence.And the steam vent on buffer air bag outer casing tube body 10 tops can be avoided occurring between impact bag and the outer casing tube body pressure and change when buffer air bag is inflated or subsided.
Experimental results show that, the valve control formula anesthetic machine/respirator waste scavenging system of present embodiment can constant negative pressure continue the waste gas that anesthesia machine system is discharged is attracted, automatically adjust internal pressure and captivation through self mechanical system, when removing medical waste gas, do not increase SR, do not influence machine intimate pressure, not limited by the influence of absorbability, no working time, and can be applicable to the treatment respirator.Waste gas is discharged outdoor via the central suction system, thereby has protected the depuration quality of operating room and intensive care unit(ICU) internal medium better, and the various waste gas of having avoided overflowing are to medical worker and other patient's health affected.
