Abstract
The utility model discloses a kind of trachea cannulas and ventilator connecting tube, including plastic film capicitor, are respectively arranged with breathing machine connector and gas-tpe fitting at plastic film capicitor both ends；Plastic ripple tube cavity is divided into admission line and outlet pipe by partition, is respectively arranged with breather check valve and outgassing nonreturn valve on admission line and outlet pipe；Admission line includes left and right pipeline, the opposite end of left and right pipeline is provided with and communicated with reclinate left and right bending section, the length of left bending section is greater than the length of right bending section, the top outer rim of left and right bending section is provided with humidification bottle connection external screw thread, is provided with strainer in the pipeline of right bending section.The utility model advantage is that structure is simple, using effect is good.Pipeline uses bellows-like structure, and the space that can be stretched is larger, easy to install and use；Air can be introduced into humidification bottle before entering human body and humidify, and can prevent the gas too dry of ventilation from causing patient uncomfortable, make to moisten in patient airway.
Description
Technical field
The utility model relates to medical instruments, more particularly, to a kind of trachea cannula and ventilator connecting tube.
Background technique
Connecting tube between existing Anesthesia machine and trachea cannula is one three corrugated connecting tubes, wherein both ends with exhale
Suction machine is connected, and respectively air inlet pipe and an air outlet pipe, the both ends being connected with ventilator merge into one and are connected with trachea cannula, also have
Some simple respirators are that a snorkel had both played the role of air inlet or played outlet.In the compressor of ventilator after connection
Contracting effect of relaxing is lower to provide the power of air inlet and outlet, changes the direction of gas in snorkel.The prior art is a snorkel
Road plays the role of ventilation, and cannot its wetting and filtering.Because compressor by gas input person's windpipe be through
It crosses trachea cannula and is directly entered intrapulmonary, without the wetting and mucomembranous surface filtering dust by nasal cavity and the mucous membrane of pharyngeal cavity and carefully
The effect of bacterium loses a large amount of body fluid by air flue so ventilator is easy to cause drying in patient airway after ventilating for a long time,
Lead to patient's postoperative discomfort；And may bring bacterium or dust in Patients with Lung into after breathing machine ventilation causes patient to be easy
Existing pulmonary infection, so safety is poor.
Summary of the invention
The utility model aim, which is to provide, a kind of humidifying and can filter the trachea cannula and ventilator of dust from gas
Connecting tube.
To achieve the above object, the utility model can take following technical proposals:
Trachea cannula described in the utility model and ventilator connecting tube, including plastic film capicitor, in the plastic ripple
Pipe both ends are respectively arranged with breathing machine connector and gas-tpe fitting；The plastic ripple tube cavity is divided into admission line by partition
And outlet pipe, breather check valve and outgassing nonreturn valve are respectively arranged on the admission line and outlet pipe；It is described into
Feed channel includes left and right pipeline, and the opposite end of the left and right pipeline is provided with and communicated with reclinate left and right bending section, institute
The length for stating left bending section is greater than the length of right bending section, and it is outer that the top outer rim of left and right bending section is provided with humidification bottle connection
Screw thread is provided with strainer in the pipeline of right bending section.
The gas-tpe fitting is the bend pipe being bent upwards.
The utility model advantage is that structure is simple, using effect is good.Pipeline uses bellows-like structure, can stretch
Space is larger, easy to install and use；Humidification bottle can be screwed on left and right bending section in venting process, air into
It can be introduced into humidification in humidification bottle before entering human body, can prevent the gas too dry of ventilation from causing patient uncomfortable, make patient airway
It is interior wet；The liquid in humidification bottle and strainer can filter out dust and bacterium in gas simultaneously, be conducive to the life of patient
Health；Strainer, which can also be crossed, prevents the excessive liquid caused in humidification bottle of gas pressure from flowing directly into intratracheally, securely and reliably.?
It can be put into the drug for atomization in humidification bottle, can be treated while patients surgery operates.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown, trachea cannula described in the utility model and ventilator connecting tube, including plastic film capicitor 1, in institute
It states 1 both ends of plastic film capicitor and is respectively arranged with breathing machine connector 2 and gas-tpe fitting 3；1 inner cavity of plastic film capicitor passes through partition
4 are divided into admission line and outlet pipe 5, and 6 He of breather check valve is respectively arranged on the admission line and outlet pipe 5
Outgassing nonreturn valve 7；The admission line includes left and right pipeline 8,9, and the opposite end of the left and right pipeline 8,9 is provided with and communicated with
Reclinate left and right bending section 10,11, the length of the left bending section 10 is greater than the length of right bending section 11, left and right curved
The top outer rim of tune 10,11 is provided with humidification bottle connection external screw thread 12, is provided with strainer 13 in the pipeline of right bending section 11；
The gas-tpe fitting 3 is the bend pipe being bent upwards.
