CN202605479U - Artificial airway oxygen inhalation catheter - Google Patents

Abstract

The utility model provides an artificial airway oxygen inhalation catheter which comprises a main body catheter, an elastic air bag, an oxygen supply tube and an automatic reset safety valve controlled by pressure, wherein one end of the main body catheter is an opened trachea connection port, and the other end of the main body catheter is connected with the elastic air bag. The elastic air bag is connected with the oxygen supply tube which is connected with the automatic reset safety valve through a three-way pipe. A mesh-shaped hollow ventilation hole is arranged on the main body catheter. The artificial airway oxygen inhalation catheter can provide large oxygen flow quantity, simultaneously can achieve the purpose of monitoring breathing conditions of patients in real time and reducing discomfortable symptoms of the patients in catheter inserting, and is improved in safety.

Description

A kind of artificial airway's Oxygen uptaking catheter

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of medical catheter.

Background technology

The caliber of existing Oxygen uptaking catheter oxygen supply pipe is thinner, to having set up artificial airway's patient, often is difficult to when oxygen demand is big be met; Air-flow velocity was more anxious when oxygen flow was big, caused air flue dry, and sputum is dry and hard, and patient is easy to generate uncomfortable sensation, also was difficult to situation such as monitoring patient's breath frequency and respiratory intensity simultaneously.And when using Oxygen uptaking catheter, conduit is prone to stopped up by the secretions of air flue, or because cough, oxygen flow is big etc., and conduit is prone to go out air flue and the phenomenon that exists oxygen to throw off, has certain potential safety hazard.

The utility model content

To the deficiency of prior art and the problem of above-mentioned proposition, this utility model provides a kind of artificial airway's Oxygen uptaking catheter, comprising:

One main catheter body,

One elastic bag,

One oxygen supply pipe,

One be stressed control automatic resetting relief valve

Main catheter body one end connects elastic bag for open trachea connector, the other end; Said elastic bag and oxygen supply pipe join, and said oxygen supply pipe is connected with automatic resetting relief valve through tee T.

Have the passage of a netted hollow out on the said main catheter body.

In the use; The trachea connector of said main catheter body one end is connected with patient's trachea intubate or catheter for tracheostomy; The passage of netted hollow out and atmosphere (sputum aspirator tube can be inhaled expectorant through the openwork part insertion air flue of passage in case of necessity), the said main catheter body other end connects elastic bag, and elastic bag and oxygen supply pipe join; The oxygen supply pipe other end connects apparatus of oxygen supply, and said oxygen supply pipe is connected with automatic resetting relief valve through tee T.

The beneficial effect of this utility model is:

1, the elastic bag that causes from patient respiration flexible, medical personnel can be observed patient's breath intensity, help the diagnosis of the state of an illness and the monitoring of patient;

2, elastic bag plays the effect of buffering and gas storage, and air-flow flattens slow, more all even soft through the elastic bag flow velocity, make the patient's breath activity smooth and easy more freely;

3, open pore on the breather, the steam that produces in the time of can making patient respiration in time distributes, and can not be trapped in airway or the air bag, causes air inlet not smooth, has also avoided the excessive uncomfortable problem of patient respiration that causes of humidity.

4, the setting of automatic resetting relief valve can prevent that the pipe internal pressure that causes is excessive damage instrument or patient is uncomfortable owing to pipeline folding is pressed, and presses when serious the pressure release of upspringing automatically of relief valve spool at folding, and pressure solutions resets except that back valve core.

The specific embodiment

As shown in Figure 1, this utility model provides a kind of artificial airway's Oxygen uptaking catheter 10, comprising:

One main catheter body 12,

One elastic bag 14,

One oxygen supply pipe 16,

One be stressed control automatic resetting relief valve 18,

Main catheter body 12 1 ends connect elastic bag 14 for open trachea connector, the other end, and said elastic bag 14 joins with oxygen supply pipe 16 1 ends, and said oxygen supply pipe 16 is connected with automatic resetting relief valve 18 through tee T 62.

Said main catheter body 12 is established the passage 22 of a netted hollow out.

This utility model is not limited to above-mentioned embodiment; If spirit and scope that the various changes or the modification of this utility model do not broken away from this utility model; If these are changed and modification belongs within the claim and equivalent technologies scope of this utility model, then this utility model also is intended to comprise these changes and modification.

Claims (2)

1. artificial airway's Oxygen uptaking catheter comprises:

One main catheter body,

One elastic bag,

One oxygen supply pipe,

One be stressed control automatic resetting relief valve

Main catheter body one end connects elastic bag for open trachea connector, the other end; Said elastic bag and oxygen supply pipe join, and said oxygen supply pipe is connected with automatic resetting relief valve through tee T.

2. Oxygen uptaking catheter as claimed in claim 1 is characterized in that: the passage that has a netted hollow out on the said main catheter body.
