Description

Extension tube of breathing machine

Technical Field

The utility model relates to the field of medical instruments, in particular to an oxygen conveying pipe fitting for communicating a tracheal cannula of a patient with a respirator.

Background

At present, patients with severe pulmonary diseases, central respiratory failure, peripheral respiratory failure, organ postoperative and the like need mechanical ventilation and oxygen delivery, so that the device is an effective means capable of manually replacing the autonomous ventilation function, and can play a vital role in preventing and treating respiratory failure, reducing complications and saving and prolonging the lives of the patients. When the respirator is used, the input oxygen must be kept at a certain humidity as much as possible, so that the stimulation to the respiratory tract of a patient during oxygen inhalation can be reduced, and the safe and effective oxygen inhalation of the patient is ensured.

The extension tube of the respirator is a fitting of the respirator and mainly comprises a threaded tube, an extension tube, a patient interface and a machine interface. The respiratory extension tube is a connecting device used between a respiratory tracheal catheter of a person and a respirator, so as to ensure that the tracheal catheter cannot be pulled by a pipeline of the respirator, and can also be used for sucking phlegm. Can also be separately connected to the tracheal catheter for absorbing phlegm and connecting the damp-heat exchanger to prevent the phlegm from directly blocking the exchanger to suffocate the patient.

In the extension tube of the respirator in the prior art, the sputum suction hole of the cavity is sealed by the elastic sealing cover, and the sealing effect is not good; when the mask is used for a long time, the oxygen inhalation concentration of a patient can be reduced, the mask can rebound to pollute the sputum suction tube in the sputum suction process, sputum is easy to overflow and splash, and the risk of cross infection of adjacent disease areas is increased; moreover, when the sputum suction operation is performed, when the right hand wears the sterile glove for sputum suction and holds the sputum suction tube, the medical staff has difficulty in opening the sputum suction port with the left hand.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model aims to provide the extension tube of the respirator, which has good air tightness and can avoid sputum overflow and spitting in the sputum suction process.

In order to overcome the technical defect, the utility model adopts the technical scheme that: the utility model provides a respirator extension tube, includes the cavity, and the bottom of cavity is seted up one and is inhaled the phlegm hole, inhale phlegm hole department and set up the check valve, the check valve extends has two petals that can open and shut and be used for preventing oxygen reverse through inhaling the phlegm hole.

Furthermore, the cavity is connected with a rotary cover for sealing the sputum suction hole through a fulcrum, and the rotary cover rotates around the fulcrum.

Furthermore, a buckle structure is arranged between the cavity and the screw cap.

Furthermore, the sputum suction hole is of a hemispherical concave structure.

By implementing the technical scheme of the utility model, the one-way valve is arranged at the sputum suction hole, so that oxygen cannot generate reverse flow in the cavity, the sputum suction hole is effectively sealed, sputum overflow and splashing in the sputum suction process are avoided, the risk of cross infection in a ward area is reduced, and the medical safety of the respiratory extension tube is improved.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 4, the ventilator extension tube mainly comprises a cavity 1, a patient interface end 2, a threaded tube 3, a ventilator interface end 4 and a screw cap 5. The chamber 1 has two oxygen ports 1.2, which are arranged at 90 degrees. The two openings are respectively communicated with a patient interface end 2 and a threaded tube 3, and the threaded tube 3 is connected with a respirator interface end 4.

The inside of the cavity 1 is also provided with a sputum suction hole 1.1, the sputum suction hole 1.1 is integrally designed to be hemispherical concave, and the hemispherical concave part is convenient for inserting a sputum suction pipe. The top assembly spiral cover 5 of cavity 1, spiral cover 5 is connected with cavity 1 through fulcrum 6, and spiral cover 5 can produce around fulcrum 6 and rotate to play and open and sealed the function. The rotary opening structure can be positioned all the time after being opened, and the automatic sealing condition caused by elasticity of the traditional resilience structure is avoided, so that the sputum suction hole and the smoothness of the sputum suction pipe are kept.

The periphery of the top of the cavity 1 is provided with a clamping point 1.3, the periphery of the inner side surface of the spiral cover 5 is provided with a buckling point 5.1, and the clamping point 1.3 and the buckling point 5.1 are buckled with each other, so that the spiral cover 5 tightly seals the sputum suction hole 1.1 of the cavity, and the operation of a sputum aspirator is convenient. When the sputum suction operation is performed, when the right hand wears the sterile gloves for sputum suction and holds the sputum suction tube, the medical staff can conveniently open the cap of the sputum suction port with the left hand.

The sputum aspirating hole is provided with a one-way valve 7, the one-way valve 7 extends with two petals 7.1, and the petals face the mouth end of the patient. The two petals are symmetrically arranged and are arranged in a duckbill shape. The two sealing petals of the duckbill one-way valve can block the sputum suction tube by means of the elasticity of the two sealing petals under the action of pressure difference, so that the sputum suction tube and the sputum suction hole are completely sealed, and sputum splashing and cross infection of a ward are prevented. The check valve is made of a silica gel material, and has the advantages of good sealing performance, flexible application and convenient operation.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
