Abstract
The utility model relates to a breathing machine pipeline with double-layer heat preservation, which comprises a humidifying tank that is connected with an air inlet pipeline; the humidifying tank is also connected with a double-layer pipeline; an inner pipe of the double-layer pipeline is connected with a patient pipe; an air outlet end of the inner pipe is provided with a one-way valve; and an outer pipe is connected with an expiratory air pipeline. The breathing machine pipeline effectively guarantees that the temperature and the humidity of the air flow entering the patient body are constant when a breathing machine ventilates.
Description
Technical field
This utility model relates to a kind of double-layer heat insulation breathing circuit that has.
Background technology
Along with the development of critical care medicine, the application of respirator is increasingly extensive, has especially brought into play important effect in the treatment of in recent years severe acute respiratory syndrome (SARS) and novel influenza A.Breathing circuit is the important component part of respirator, and the breathing circuit of using clinically is made up of air inlet pipeline and outlet pipe at present, all is relatively independent two tubes.
When using, gas adds gentle humidification through humidification pot earlier, sends into patient's pulmonary through aspirating pipeline, gets back to respirator through the expiration pipeline during exhalation.We are in process of clinical application, and when finding that gas arrives the length of the about 1-1.5 rice of disease population end through humidification pot, temperature promptly obviously descends, and humidity also descends immediately, and clammy air can cause damage to the pulmonary to patient.The influence factor comprises many-sides such as room temperature, air mobility status, tidal volume size, if heighten the temperature of humidification pot, again might be too high because of gas temperature, and cause the patient's trachea mucosa to burn, consequence is more serious.For addressing this problem, the heating seal wire is placed by the producer that has in the middle of trachea, and adds a thermal detector at the disease population end, and feedback is regulated the temperature of humidification pot.But this feedback regulation is obviously delayed in time, causes the temperature big rise and big fall, and effect is unsatisfactory, and price is but very expensive.Therefore, press for a kind of pipeline of convenient and practical assurance constant temperature and humidity.
Summary of the invention
At above-mentioned deficiency, this utility model provides a kind of double-layer heat insulation breathing circuit that has, and it is simple in structure, and is easy to use, can guarantee that the E Wendu of air-flow, humidity are constant.
This utility model is realized by following technology:
A kind of double-layer heat insulation breathing circuit that has, it comprises humidification pot, humidification pot is connected with air inlet pipeline, described humidification pot also has Double layer pipeline and is connected with one, the interior pipe that has Double layer pipeline is connected with patient tube, is provided with one-way cock in the outlet side of interior pipe, and outer tube then is connected with the expired gas pipeline.
Be provided with support column between pipe and outer tube in described.
Breathing circuit of the present utility model is made up of interior pipe and outer tube, and the centre has short column to support.Gas is sent in patient's lung through the internal layer pipeline behind humidification pot heating and moistening device, during exhalation, gets back to respirator through outer tube.Employing has double layer design, has obviously reduced heat radiation, and the air inlet pipeline that mediates can not be subjected to that ambient temperature and air are mobile to be influenced.The double expired gas passage of doing of two-layer intermediary interlayer can make full use of reverse the heating of heat of expired gas, the temperature and humidity of air inlet pipeline in the middle of further guaranteeing.Expired gas is corresponding to patient's body temperature, can regulate the body temperature of the temperature of air-flow near patient as far as possible, avoids the damage to lung.
The beneficial effects of the utility model are: the machine that can effectively ensure respiration enters the intravital gas flow temperature of patient when ventilating, humidity is constant.
Description of drawings
Fig. 1 is for having double-layer heat insulation breathing circuit structural representation;
Wherein, 1, air inlet pipeline, 2, humidification pot, 3, interior pipe, 4, patient tube, 5, patient's lung, 6, outer tube, 7, expired gas pipeline.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is described further.
Among Fig. 1, it comprises humidification pot 2, and humidification pot 2 is connected with air inlet pipeline 1, described humidification pot 2 also has Double layer pipeline and is connected with one, the interior pipe 3 that has Double layer pipeline is connected with patient tube 4, is provided with one-way cock in the outlet side of interior pipe 3, and 6 of outer tubes are connected with expired gas pipeline 7.The gas that patient's lung 5 is breathed out is discharged by expired gas pipeline 7.
Pipe 3 and 7 of outer tubes are provided with support column in described.
When using, breathing circuit is connected to respirator and meets patient according to correct order.Routinely, do not need special damage, the gas of constant temperature, constant humidity can the machine of ensuring respiration be provided.
Claims (2)
1. one kind has the double-layer heat insulation breathing circuit, it comprises humidification pot, humidification pot is connected with air inlet pipeline, it is characterized in that, described humidification pot also is connected with a Double layer pipeline, the interior pipe of Double layer pipeline is connected with patient tube, is provided with one-way cock in the outlet side of interior pipe, and outer tube then is connected with the expired gas pipeline.
