Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly, to a kind of absorption type tongue retractor.
Background technology
Glossoptosis can block air flue, the airway obstruction as caused by cannot release glossoptosis in time, and tongue body traction is opened, will be led
Cause airway obstructive acid poisoning.Obstructive acid poisoning leads to serious consequence, or seriously affects rescue effect.Therefore, rapidly
And quickly open tongue traction, airway obstruction caused by releasing glossoptosis is extremely important.
When bottleneck throat checks, when examining bottleneck throat, need to stablize exposure bottleneck throat.But due to the presence of tongue, surely
Surely bottleneck throat is exposed to be not easy to.Also it is moment to observe bottleneck throat using spatula.
When occurring bottleneck throat pain in kinsfolk, often want to look at tonsil, such as whether observe tonsil surface
The case where having pus point (whether discriminating is suppurative tonsillitis), observing bottleneck throat.There is the people of common sense often to use spoon
Son or chopsticks substitute the spatula of Clinical practice.In most cases, operation is not very successful, the case where can't see bottleneck throat,
Also cause the discomfort of patient.When voluntarily observing, it is more difficult to complete operation.
Clinical common method：1, tongue front is clamped using tongue forceps or tissue forceps, pulled forward, release glossoptosis.2, make
Tongue is pulled outlet plenum by the tongue front that patient is lived with gauze wrapped with hand, and exposure bottleneck throat releases glossoptosis.Family makes
Method：1. observe bottleneck throat, with replacements such as spoon or chopsticks, often cause discomfort, and effect is uncertain.2. urgent
In the case of, it needs the tongue body of patient pulling out oral cavity, when unblocking, a variety of provisional tools often result in damage to tongue body.
The shortcomings that existing method：1, tongue forceps or tissue forceps drawing tongue tend to cause the damage of tongue；When 2, pulling
Do not allow to be fixed easily in the position for clamping tongue；3, tongue drawing effect is unstable, is easy to slip；When 4, operating, patient is pulled with hand
Tongue easily causes the feeling of patient's discomfort.
Based on this, the present invention provides a kind of absorption type tongue retractors to solve above-mentioned technical problem.
Invention content
The purpose of the present invention is to provide a kind of absorption type tongue retractors, are not taken pains with solving existing tongue traction effect
The technical issues of slippage.

Together.
Different size of tongue body traction cover may be used for different patients.Tongue body traction cover basic configuration connects with tongue body
Close arc-shaped, one end is provided with arc opening, is used for the entrance of tongue body, and gas outlet is arranged in the other end.Can be had according to different people
Many kinds, it is larger that one is volumes, and arc opening is larger, adapts to the larger adult of tongue body.Another kind be opening smaller size smaller compared with
Small, adapt to the smaller adult of tongue.The third is the child form of volume minimal openings minimum.For tongue body it is bigger or ratio
Smaller, it can be with individually designed etc..Preferably, the gas outlet of the tongue body traction cover is provided with check valve, is conducive to negative pressure
Formation.
Optionally, the vacuum suction system includes negative pressure ball, and the inlet end of the negative pressure ball is connect with the connecting tube,
The outlet side of the negative pressure ball is provided with outgassing nonreturn valve.
By squeezing negative pressure ball, negative pressure is generated, to complete the attraction to tongue body, is attracted by manually completing, is suitble to face
Bed rescue, it is faster.
Optionally, further include negative-pressure suction pipe, the outlet side of the negative pressure ball is connected to one end of the negative-pressure suction pipe,
Junction is provided with connection valve.
Optionally, the other end of the negative-pressure suction pipe is connected with vacuum extractor.
Vacuum extractor is connected by negative-pressure suction pipe, naturally it is also possible to be connected remaining negative pressure suction device, be compared in this way
Attract the vacuum suction that more stable constant pressure is provided manually, to ensure the stability attracted.
Optionally, the vacuum suction system includes connecting hole, and the connecting tube is goed deep into one end of the connecting hole
With the tongue body traction cover gas outlet be connected to, the other end is connected to by outgassing nonreturn valve with automatic traction controller, it is described oneself
Dynamic traction controller is connected to by negative-pressure suction pipe and drawing control line with tongue retractor control unit；The tongue retractor control
Unit processed is sequentially connected with BOLD contrast.
It is this to be suitable for leading to the patient of airway obstruction due to glossoptosis, it is suitable for obstructive sleep apnea low
Syndrome (OSAHS) type.Tongue traction cover is fixed on to the tongue body front of patient with most suitable negative pressure, negative pressure traction tube is very thin, no
Patient is influenced to shut up sleep.Automatic traction controller can generate vacuum suction, be controlled by tongue retractor control unit, tongue traction
Vacuum suction is implemented in the monitoring of one BOLD contrast of device control unit.
Optionally, the connecting tube is provided with one end of the outgassing nonreturn valve and is additionally provided with breathing mask, the connection
Pipe is connect across the breathing mask with the unidirectional air outlet valve.
It is to facilitate patient respiratory that breathing mask, which is arranged, is helped for sleep.
The absorption type tongue retractor provided by the invention after covering on tongue body traction on tongue body, uses when in use
Vacuum suction system generates negative pressure, to which tongue body to be fixed on by vacuum suction in tongue body traction cover, is led by pulling tongue body
Draw cover, tongue body can be pulled forward or other are operated.
The absorption type tongue retractor provided by the invention has negative pressure to hold tongue by tongue body traction cover, tongue be by
It wraps, rather than is vised, tongue is not easy injury, and also not uncomfortable feeling, safe.Moreover, because the length of negative pressure
Time exists, and pulls effect stability, is not in slip, more convenient when observation, can clearly observe for a long time.
