Description

A kind of dedicated sputum aspirator for Pediatric Clinic

Technical field

The invention belongs to the field of medical instrument technology, are related to a kind of sputum aspirator, and in particular to one kind is used for Pediatric Clinic Dedicated sputum aspirator.

Background technique

On Pediatric Clinic, it often will appear sputum in the respiratory tract of infant, this just needs medical staff timely to trouble Sputum in person's respiratory tract is purged, and clinically mostly the sputum in patients with respiratory tract is sucked out using sputum aspirator；Specific behaviour When making, generally requires two people and suction sputum operation is carried out to patient, a people carries out suction sputum to patient using sputum aspirator, and another people is suffering from Person behind taps the back of patient, and so as to the better suction sputum of patient, but both sides operate be unfavorable for medical care people simultaneously The operation of member cooperates the bad pain that but will increase patient.

In addition in practical operation, the more and sticky situation of the sputum of patient is frequently encountered, sputum is caused to be difficult to be inhaled Out the case where；Medical staff needs first to extract the drainage tube in patient mouthful at this time, then injects to patient's throat a certain amount of Physiological saline or resolving sputum medical fluid, then the sputum of patient's throat is sucked out by reinserting drainage tube；But when in patient mouthful Sputum it is more when, it is necessary to the plug drainage tube of medical staff repeatedly to patient carry out suction sputum, plug drainage tube repeatedly in this way It is easy that the respiratory mucosa of patient is caused to damage, and extends the time of suction sputum, increase the pain of patient, increase medical care The work difficulty of personnel.

Summary of the invention

For above situation, to overcome the shortcomings of existing technologies, the present invention provides a kind of for the dedicated of Pediatric Clinic Sputum aspirator, effective solution existing sputum aspirator patient's suction sputum effect more to sputum and sticky bad problem.

To achieve the above object, the invention adopts the following technical scheme: a kind of dedicated sputum aspirator for Pediatric Clinic, Including cabinet, cabinet includes bottom plate, and bottom plate is equipped with power device, and power device includes motor, and interval is connected on motor and is passed Motivation structure；The intermittent drive mechanism includes being connected to the motor the main transmission structure connect, and interval is connected on main transmission structure and is passed Dynamic structure, cabinet are equipped with the locking structure matched with intermittently-driving structure；Negative pressure dress is connected on the main transmission structure It sets, sputum aspirator is removably connected on negative pressure device；It is connected in the intermittently-driving structure and kowtows back device and filled with back is kowtowed Set the chemicals dosing plant moved synchronously；It is connected with interior negative tube on the negative pressure device, is equipped with and chemicals dosing plant phase in interior negative tube The interior drug discharging tube of connection；The sputum aspirator includes drainage tube, is equipped with outer drug discharging tube corresponding with interior drug discharging tube in drainage tube.

Compared with prior art, the invention has the following advantages:

1, in the use of the present invention, while carrying out negative pressure suction sputum to patient, using chemicals dosing plant to the throat of patient Place's injection Apophlegmatisant, dilutes sputum, the sputum of patient's throat is drawn convenient for the sputum aspirator tube on sputum aspirator；It is filled using back is kowtowed It sets and taps patient back and make sputum in patient's expectoration respiratory tract, and inject Apophlegmatisant dilution sputum simultaneously, filled using negative pressure Suction sputum is set, the effect of suction sputum is improved.

2, it is matched using main transmission structure, negative pressure device with sputum aspirator, the lasting sputum to patient's throat is inhaled Out, prevent sputum from depositing；Using intermittently-driving structure, chemicals dosing plant, kowtow back device match, make the sputum in patients with respiratory tract The discharge of interval simultaneously sprays Apophlegmatisant, prevents sputum discharge is more from depositing in patient's throat, and prevents from kowtowing back device and strike It hits that frequency is too fast to be caused to damage to patient back, improves the comfort of patient, dosing when also preventing chemicals dosing plant from continuing dosing It is more, medical fluid is wasted, and cause patient uncomfortable；It kowtows back device and chemicals dosing plant moves synchronously, while expectoration, sputum is sprayed Drug improves the effect of Apophlegmatisant resolving sputum.

3, in the use of the present invention, can be according to patient's sputum the case where, replaces the model of syringe, by replacement port to change The resolving sputum medical fluid for becoming injection patient's throat, improves suction sputum effect of the invention.
