Description
Technical field
The utility model belongs to medical apparatus technical field more particularly to a kind of closed sputum aspirator.
Background technique
In the field of medical instrument technology, to assist patient's expectoration, sputum aspirator tube is clinically largely used, is connected by Negative pressure machine
Connect sputum aspirator tube, by sputum aspirator tube from the interface being installed on person's windpipe be deep into it is intratracheal after, pinch the tight interface with hand, make interface
It is interior to form closed space, lifting then is carried out to sputum aspirator tube and is entered with Shen, realizes suction sputum.Currently used sputum aspirator tube is style of opening
, medical staff needs to wear gloves and mask before suction sputum operates, and a large sheets of paper is laid with before thoracic, for preventing suction sputum
The droplet generated in the process and the sputum being pasted on sputum aspirator tube, and pinched tightly after the interface in sputum aspirator tube insertion patient's trachea
The interface, the air inlet that will lead on ventilator leak, and so that patient is temporarily unable to intussusception to oxygen, medical staff is needed to exist
Suction sputum operation is completed in 15 seconds, nursing staff is thus needed to have very skilled operation horizontal, not so will appear patient's asphyxia
Risk.It requires to separate artificial airway with ventilator during each suction sputum, interrupts mechanical ventilation, sputum aspirator tube will be exposed to sky
It is operated in gas.Therefore, the problems such as anoxic, cross-infection and environmental pollution is inevitably caused, while also will cause
The variation of vital sign.Therefore present clinical use is usually sealed sputum aspirator tube, and existing sealed sputum aspirator tube
Pencil can only to the phlegm outside sputum aspirator tube carry out humidifying so that the phlegm inside sputum aspirator tube can not may cause suction by complete humidifying
Blocking inside phlegm pipe.
Utility model content
The purpose of this utility model is to provide a kind of closed sputum aspirators, prevent phlegm from blocking sputum aspirator tube, improve suction sputum
Efficiency.
In order to achieve the above object, the base case of the utility model are as follows: closed sputum aspirator, including sputum aspirator tube, suction sputum
Pipe both ends are connected separately with tee pipe fitting and negative pressure connector, and sputum aspirator tube outer sheath is equipped with protective film, and protective film both ends are fixed respectively
It is connected to tee pipe fitting and negative pressure connector, the another both ends of tee pipe fitting are respectively joint for respiratory device and gas-tpe fitting, close on tee pipe fitting
Envelope is connected with medicine-pouring pipe, and the medicine-pouring pipe is located at one end in tee pipe fitting and is equipped with the openable chemicals-injection mechanism that is pressurized, institute
It states and offers several columns side sucker on the side wall of sputum aspirator tube.
The working principle of this base case is to be with beneficial effect: in use, negative pressure connector is connected with Negative pressure machine, exhaling
Suction head is connected with ventilator, and gas-tpe fitting is connected with tracheae, and medical fluid is filled in medicine-pouring pipe.Then sputum aspirator tube is slowly inserted into
Patient's is intratracheal, pushes medicine-pouring pipe to contact the chemicals-injection mechanism of injection tube end with the side wall of sputum aspirator tube, the side wall of sputum aspirator tube
A pressure can be applied to chemicals-injection mechanism.It can be opened since chemicals-injection mechanism is under pressure, when chemicals-injection mechanism and sputum aspirator tube
When side wall contacts, chemicals-injection mechanism can be opened, so that the medical fluid in pencil can be flowed out from chemicals-injection mechanism, and at this time chemicals-injection mechanism with
The side wall of sputum aspirator tube contacts, so the medical fluid of outflow can be flow on the side wall of sputum aspirator tube, so that medical fluid can be along sputum aspirator tube
Endwall flow of the side wall to sputum aspirator tube.If due to offering dry side sucker on the side wall of sputum aspirator tube, so a part of medical fluid can lead to
It crosses side sucker to enter inside sputum aspirator tube, some medical fluid reaches the end of sputum aspirator tube along the side wall of sputum aspirator tube, to make
Humidifying can not only be carried out to the phlegm outside sputum aspirator tube by obtaining medical fluid, and can carry out humidifying to the phlegm inside sputum aspirator tube, so that
Sputum aspirator tube can easier suction sputum, prevent phlegm from blocking sputum aspirator tube, improve suction sputum efficiency；Simultaneously because on the side wall of sputum aspirator tube
Flow medical fluid so that sputum aspirator tube also patient tracheae contact when, stimulation of the sputum aspirator tube to tracheae can be reduced, mitigate patient's
Pain.When the sputum suction hole of suction sputum tube end is blocked, the normal operation of suction sputum work also can guarantee by side sucker suction sputum.

Under the action of mutually stagger apopore with inlet opening, the end of the one end of adjustable pipe far from recessed pipe offer with inside adjustable pipe
The dripping hole of connection.Such setting can be such that medical fluid enters inside sputum aspirator tube, prevent phlegm from blocking sputum aspirator tube, improve suction sputum effect
Rate.
Further, protrusion is provided on sputum aspirator tube side wall, protrusion is located between adjacent two column side sucker.Side is opened up on side wall
Sucker is easy to be attached on pharyngeal or tunica mucosa tracheae, causes mucosal congestion and edema, it is possible to obstructing airway, therefore protrusion is set, it keeps away
Exempt from side sucker to be attached on pharyngeal or tunica mucosa tracheae
Further, sputum aspirator tube is hose made of igelite, and tube body is colourless, transparent.Igelite has
Excellent toughness, elasticity and flexibility can reduce and go deep into throat to patient's bring feeling of pain.
Further, suction sputum tube end is spherical setting.Compared to common sputum aspirator tube, end is in the sputum aspirator tube of spherical setting
It can be damaged to avoid tracheae of the sputum aspirator tube to patient.
Further, there is label on sputum aspirator tube.In order to which medical staff observes the insertion depth of sputum aspirator tube.
