Description

A kind of type breathing-machine humidification pot
Technical field
This utility model relates to armarium field of accessories, is specially a kind of type breathing-machine humidification flow container that type breathing-machine humidification device is carried out to constant liquid feeding.
Background technology
Respirator is the necessary supplementary instrument that patients with respiratory failure maintains breathing, assurance ventilation, during respirator assisted respiartion, the gas of carrying to patient airway is the mist of oxygen and air, and the temperature while entering patient airway, humidity is common and room air is basically identical.And the humidifier that respirator is equipped with is to guarantee that by heating humidification fluid (sterilized water for injection) gas that patient sucks reaches enough temperature and humidities, thus the generation of protection patient airway, reduction Ventilator Associated Pneumonia.
Current humidification fluid of breathing machine is clinically added with following several mode:
1, disconnect breathing circuit, pry open sterilized water for injection bottle stopper, directly topple over humidification fluid and connect pipeline to waterline.Disconnect pipeline and just lost the support function of respirator, especially must be careful to patient with severe symptoms.The as above method of pressing again after humidification fluid consumes is added, general 2 ~ 3 hours liquid feedings once, be busy with one's work and often occur adding water excess or dry combustion method phenomenon, make patient suck the temperature and humidity of gas extremely unstable, easily cause that patient's expectoration is smooth, air flue spasm, the sense of discomfort that increases patient, also easily makes humidification fluid enter respirator internal damage element.
2, use transfusion device to connect humidification fluid and regularly open the supplementary humidification fluid of switch.This method has kept the seal of pipeline, be more conducive to sterile working's principle, shortcoming is also easily to occur adding water excess or dry combustion method phenomenon, and because being manually adds water and adds water process for intermittently injecting, easily occur that water injection rate is uneven, few situation when many while causing water injection rate, and the number of water injection rate produces certain impact to humidifying effect.
3, use integrated automatic watering humidifier, advantage is automatically to maintain water level, but expensive, and is disposable use, costly, can bring very large economic pressures to patient.
Utility model content
The technical problem that this utility model solves is to provide a kind of type breathing-machine humidification pot, to solve the shortcoming in above-mentioned background technology.
The technical problem that this utility model solves realizes by the following technical solutions:
A kind of type breathing-machine humidification pot, comprise humidification pot tank body, tank base is provided with heat-conducting metal base, top has air inlet, gas outlet and inlet, wherein, in humidification pot tank body, be also provided with an automatic liquid supply device, described automatic liquid supply device is one or two rank tubular construction, the upper exponent part of this two rank tubular construction is a long straight tube structure, its top is connected with inlet, bottom is connected on the inverted funnel structure of lower exponent part, and in this funnel structure, is also provided with the ball float that an external diameter is greater than long straight tube internal diameter; Between described funnel structure bottom and heat-conducting metal base, leave the gap of 10 ~ 15mm, and in both sides, be provided with U-shaped gap, described heat-conducting metal base top is provided with circle convex annular rank, and convex annular rank height is 20 ~ 30mm, and passes the U-shaped gap of funnel structure.
In this utility model, the gap between described funnel structure bottom and heat-conducting metal base is preferably 15mm.
In this utility model, the height on the convex annular rank on described heat-conducting metal base is preferably 20mm.
In this utility model, described inlet top connects closed transfusion device, and this closed transfusion device preferably adopts micro-transfusion system.
When humidification pot tank body of the present utility model can the water yield in humidification pot reach a certain height, utilize the ball float floating in funnel structure that length straight tube structure is blocked, make closed transfusion device stop humidification fluid supply; And when humidifying tank level declines, ball float declines, closed transfusion device starts to supply with humidification fluid, guarantees that like this level control in humidification pot is in suitable altitude range.
Beneficial effect: this utility model structural design is simple, by the funnel structure increasing with ball float, carry out liquid surface height controlling in humidification pot, and then make to add the water in humidification pot to remain on certain altitude, improved the warming humidification efficiency of respirator, also having stopped humidification pot " dry combustion method " or " spill-over " phenomenon occurs, greatly improve the safety of undergoing mechanical ventilation in clinical, avoid serious malpractice to occur; Also greatly reduce medical personnel's workload.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model preferred embodiment.
Wherein: 1, gas outlet; 2, air inlet; 3, inlet; 4, humidification pot tank body; 5, long straight tube; 6, ball float; 7, upside down funnel; 8, heat-conducting metal base; 10, humidification fluid; 11, convex annular rank.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth this utility model.
Preferred embodiment referring to a kind of type breathing-machine humidification pot of Fig. 1, in the present embodiment, humidification pot tank body 4 is molded on heat-conducting metal base 8, on its tank body upper surface, have gas outlet 1, air inlet 2 and inlet 3, wherein, air inlet 2 connects the feeder of respirator end, and 1 rear portion, gas outlet connects patient respiratory device.Inlet 3 tops connect the micro-transfusion system of closed, bottom connects the long straight tube 5 in automatic liquid supply device, these long straight tube 5 bottoms are stretched in humidification pot tank body 4, and be connected with the upside down funnel 7 on rank under automatic liquid supply device endways, upside down funnel 7 lower edge both sides are provided with U-shaped gap, between bottom and heat-conducting metal base 8, leave the gap of 15mm, and in upside down funnel 7, have an external diameter to be greater than the ball float 6 of long straight tube 5 internal diameters.
