Abstract

The utility model discloses a disposable sputum aspirator which comprises an outer tube (1), an inner tube (2), a handheld seat (3) of the outer tube (1), and a handheld seat (4) of the inner tube (2). The sputum aspirator is characterized in that an axial partition board (5) is arranged at the front end of the inner tube (2); the axial partition board (5) divides the inner cavity of the inner tube (2) into two symmetric cavities; two sputum suction openings (6) are formed on the side walls of the inner tube on two sides of the axial partition board respectively; the rear segment of the inner tube (2) is a cylinder; a piston (7) is arranged in the cylinder on the rear segment of the inner tube (2); and a sputum suction opening through hole (10) is formed at the front end of the outer tube (1) in a position corresponding to one sputum suction opening (6) at the front end of the inner tube (2). The disposable sputum aspirator has the advantages of simple structure and convenient operation, and is provided with a layer of thin film, so that a patient cannot feel discomfortable or painful in the process of inserting the sputum aspirator; and the disposable sputum aspirator is disposable, so that cross infection cannot be caused.

Description

Disposable sputum aspirator

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of disposable sputum aspirator.

Background technology

Hospital will carry out tracheal intubation and inhale expectorant in oropharyngeal airway for critical patients' such as cerebral infarction, laryngemphraxis rescue at present, can keep respiratory passage unblocked effectively like this, be convenient to remove airway secretions or foreign body and pressurization oxygen supply, and be beneficial in air flue atomizing, humidifying and the air flue oxygen supply etc., if it is untimely to inhale expectorant, can cause patient to suffocate, as seen particularly important to this type of patient's suction expectorant nursing.The sputum aspirator that uses is made of sputum aspirator tube and collection expectorant chamber at present, sputum aspirator tube is transparent ebonite tube, tube wall is thicker, the tube wall front end is provided with inhales the expectorant mouth, and the rear end is a union joint, connects collection expectorant chamber, though it is simple and easy to do, but, in inserting the trachea process, easily trachea is caused certain damage and stimulation because hardness is bigger, and sputum more for a long time, easily sputum aspirator tube is stopped up, in order to reduce the damage in the intubate process, the employing flexible rubber hose that also has, but flexible rubber hose is difficult for inserting, the employing electrodynamic type sputum aspirator that also has, but owing to electrodynamic type sputum aspirator volume weighs greatly, move, clean, it is all inconvenient to give emergency treatment to a patient, can't use after the power failure, suction pressure also is difficult for regulating, if the excessive respiratory mucosa that also can damage the patient of negative pressure is reused the problem that also has cross infection simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of not only simple in structure, easy to operate, health but also patient not to have sense of discomfort and pain, can not damage respiratory mucosa, prevent the disposable sputum aspirator of cross infection.

For reaching above purpose, the technical scheme that this utility model adopted is: this disposable sputum aspirator, comprise outer tube, the hand-held seat of the hand-held seat of interior pipe and outer tube and interior pipe constitutes, interior pipe box is in outer tube, and the external diameter of interior pipe is consistent with the internal diameter of outer tube, it is characterized in that being provided with axial dividing plate at the front end of interior pipe, axially dividing plate is divided into symmetric two chambeies with the inner chamber of interior pipe, on the sidewall of the axial interior pipe of dividing plate both sides, be equipped with and inhale the expectorant mouth, the back segment of interior pipe is a cylinder, be provided with piston in the cylinder of interior pipe back segment, piston is connected with the piston rod hand holding handle by piston rod, inhales the corresponding position of expectorant mouth of the front end of the front end of outer tube and interior pipe and establishes and inhale expectorant mouth through hole.

This utility model is also implemented by following measure: be with air bag and film on the outer wall of outer tube, gas tube inserts in the air bag and film along the outer wall of outer tube, and it is cylindric that air bag and film is.

When using this utility model, grasp the hand-held seat of outer tube, earlier to inflating in the air bag and film, make its rising, in the insertion trachea, and fixing, when inhaling expectorant, pipe in the hand-held seat of pipe rotates in arresting earlier, the suction expectorant mouth of pipe front end one side aligns with the suction expectorant mouth through hole of outer tube front end in making, and hand-held again piston rod handle spurs piston, makes an intracavity of pipe in the endotracheal sputum suction, pipe in rotating again, the suction expectorant mouth of opposite side is alignd with suction expectorant mouth through hole on the outer tube, outwards spur outer tube, the suction expectorant mouth through hole of outer tube front end is in the tracheal wall position, spur the piston rod handle once more, the sputum of trachea is thoroughly sucked, and pipe in rotating again makes two to inhale the expectorant mouth all by the outer tube wall shutoff, can take out sputum aspirator this moment, destroys then.

The beneficial effects of the utility model are: simple in structure, easy to operate, owing to when inserting, thin film is arranged, so patient does not have sense of discomfort and pain, owing to be disposable use, so can not produce cross infection.
