Abstract
The utility model provides a buffering system of an anesthesia waste gas exhausting device, which comprises an upper connecting pipe, a T-shaped pipe, an adjusting valve, a lower connecting pipe, a gas storage sac, and a gas ventilation pipe, wherein the lower end of the upper connecting pipe is connected with the upper end of the T-shaped pipe; the lower end of the T-shaped pipe is connected with the upper end of the adjusting valve; the lower end of the adjusting valve is connected with the upper end of the lower connecting pipe; a branch of the T-shaped pipe is connected with the gas storage sac at the middle section position; the branch of the T-shaped pipe is connected with the gas ventilation pipe at the end position. The utility model is applied to various anesthesia machines (a tightly closed type and a half tightly closed type). The buffering system has the advantages of simple structure, low cost, convenient use and good effects.
Description
One, technical field
The utility model relates to a kind of waste gas of anesthesia remover, especially is suitable for the buffer system of a kind of waste gas of anesthesia remover of medical clinical use.
Two, background technology
In existing hospital, when anaesthetizing operation patients, all uses operating room inhalation anesthesia medicine (laughing gas, Isoflurane, enflurane etc.) in a large number.Therefore Anesthesia machine can be discharged a large amount of waste gas of anesthesia, and the air in the operating room is polluted.If the medical worker works for a long time, can be subjected in various degree influence to health so under such environment.In order to solve the operating room pollution problem, utilize underbalance effect that waste gas of anesthesia is discharged out operating-room.
At present, utilize the exhaust apparatus of compressed air, can realize above function, but have following problem by fluidic device generation continuous negative pressure effect:
1. the Anesthesia machine of different model need be set different negative pressure suction forces, the allotment of inconvenient Anesthesia machine.
2. the Anesthesia machine exhaust pipe can not be too thick, otherwise use inconvenience, if thin partially, resistance is bigger, when exhalation tidal volume (waste gas) reach 300ml or when above (hemicompact enclosed or open anesthesia machine) can not in time discharge in time second at 0.5-1, patient will occur breathing and is obstructed.
3. the negative pressure suction force that connects of Anesthesia machine outlet port is excessive, can the oxygen in the Anesthesia machine air storage bag be siphoned away, and influences the operate as normal of Anesthesia machine.
Therefore, design the waste gas of anesthesia removal system device of some models abroad.Its characteristics have:
1. the gas storage buffer container of all models all is a duricrust container.
2. all models are equipped with a buoy, determine according to the position of buoy whether negative pressure suction force is suitable.
Through some model waste gas of anesthesia removal system devices of this import of clinical use, find this apparatus structure complexity, cost is higher, and uses inconvenience.
Three, summary of the invention
The utility model provides a kind of buffer system of simple in structure, waste gas of anesthesia remover that cost is lower, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of buffer system of waste gas of anesthesia remover, comprise tube connector, T type pipe, control valve, following tube connector, air storage bag, permeability cell, the lower end of wherein going up tube connector is connected with the upper end of T type pipe, the lower end of T type pipe is connected with the upper end of control valve, the lower end of control valve is connected with the upper end of following tube connector, and the branch road of T type pipe connects air storage bag at middle section position, and the branch road of T type pipe connects permeability cell at end position.In addition, air storage bag is a soft rubber bag tank container.
The utility model has designed the waste gas of anesthesia remover of a band buffer system, its principle is: utilize compressed air to produce the continuous negative pressure effect by fluidic device, between Anesthesia machine Waste gas outlet and waste gases discharging apparatus, connected a novel buffer system, solved above-mentioned complex structure well, cost is higher, uses problems such as inconvenience.The utility model is applicable to all kinds of Anesthesia machines (closing formula and hemicompact enclosed).This buffer system is simple in structure, cost is lower, easy to use.Waste gas of anesthesia removal system device outside the comparator, design of the present utility model has with external model device difference:
1. the gas storage buffer container of external model is a duricrust container.Air storage bag of the present utility model is a soft rubber bag tank container, can direct viewing to container gas what are arranged.
2. external model waste gas of anesthesia removal system device is equipped with a buoy, determines according to the position of buoy whether negative pressure suction force is suitable.Design of the present utility model does not need this buoy, as long as watch the expansion of rubber air storage bag and contraction situation just to know whether vacuum suction is suitable.
3. design of the present utility model has a permeability cell, can introduce the air in the external world when negative pressure is big in the system, avoids the Anesthesia machine outlet port to produce negative pressure and influences the normal operation of Anesthesia machine.
When exhalation tidal volume (waste gas) reach 300ml or when above (hemicompact enclosed or open anesthesia machine) can not in time discharge in time second at 0.5-1, patient will occur breathing and is obstructed.At this moment temporarily intake resistance is near storing in zero the parts air storage bag for the waste gas that can not in time discharge, and patient's waste gases discharging apparatus when air-breathing continues waste gas remaining in the air storage bag is drained.The waste gas of discharging when Anesthesia machine is seldom the time (closed anesthesia), the vacuum suction that continues will siphon away oxygen in the Anesthesia machine air storage bag slightly greatly, influence the operate as normal of Anesthesia machine, the parts control valve, can regulate the size of negative pressure suction force, the parts permeability cell can add to the outside little air of system in the buffer system, thereby avoid the influence of waste gases discharging apparatus to Anesthesia machine simultaneously.
Four, description of drawings
The utility model is described in further detail in conjunction with the accompanying drawings.
Figure one is the schematic diagram of a kind of waste gas of anesthesia remover of the utility model buffer system.
Among the figure: 1, go up tube connector; 2, T type pipe; 3, control valve; 4, following tube connector; 5, air storage bag; 6, permeability cell.
Five, the specific embodiment
In figure one, the upper end of last tube connector 1 is connected with Anesthesia machine blast pipe (not drawing among the figure), the lower end is connected with the upper end of T type pipe 2, the lower end of T type pipe 2 is connected with control valve 3 upper ends of band scale indication, and the lower end of control valve 3 is connected with the upper end of following tube connector 4, the lower end of tube connector 4 with discharge gas end (not drawing among the figure) by the waste gas of compressed air-driven and be connected, form main gas discharge channel.Another branch road of T type pipe 2 is connected with the buffering air storage bag 5 of inflatable contraction near middle section position, the waste gas that patient is breathed out moment temporarily is stored in the air bag, the branch road of T type pipe 2 connects permeability cell 6 at end position, the other end of permeability cell 6 opens wide and communicates with atmosphere, can draw the part air from atmosphere in case of necessity, discharge gas end excessive air-breathing to Anesthesia machine to remedy waste gas.
Need to prove especially; if the equivalence of being done according to shape of the present utility model and structure changes; when the shape that it produced, structure, function etc. do not exceed the essence of these claims, specification and technical characterictic that accompanying drawing is contained, all should fall into protection domain of the present utility model.
