Abstract
The utility model relates to a laryngeal mirror, which relates to a device for examining the lumen of the human body and an auxiliary apparatus for operation or diagnosis. The existing laryngeal mirror has some deficiencies that a physic liquor switch is arranged on the upper part, and is controlled by thumbs, so, the operation is inconvenient, and in addition, the seal of the physic liquor is poor. A physic liquor control switch of the laryngeal mirror of the utility model is arranged on the side surface, and the manner of the face seal is used to overcome the insufficiencies.
Description
This utility model is a kind of laryngoscope, relates to the chamber of checking human body or device and the operation or the diagnosis auxiliary facilities of pipe.
Present laryngoscope is as 91207206.7 patent applications 88203809.5.They all have some common defectives, and one is operation inconvenience, and this mainly is because its medicinal liquid switch is located at top, need with thumb control, and the people that the adversary is little and strength is little is inconvenience especially; It two is that medicinal liquid sealing is bad, and they are by spring and line contact sealing, thus opening force greatly and seal unreliable.
In order to overcome the above-mentioned deficiency of present laryngoscope, this utility model spy has proposed a kind of laryngoscope.
Characteristics of the present utility model are side rather than the top that the medicinal liquid switch of above-mentioned laryngoscope is placed on the laryngoscope body, so that accuse pharmacy liquid switch with little mother when gripping laryngoscope; Adopted the mode shutoff medicinal liquid of face seal in addition.
Because laryngoscope of the present utility model adopts the medicinal liquid switch is put in the scheme of laryngoscope body side surface, thereby operate more conveniently, need not change hands and just can operate; Adopted the mode shutoff medicinal liquid of face seal, at this moment spring only plays a part valve core reset, thereby power is very little, only needs to refer to just press gently and can operate flexibly with little mother, and face seal is also many reliably than linear sealing.
Fig. 1 is the structure cutaway view of this utility model laryngoscope.
(1) be that medicine storing pot, (2) are that sealing ring, (3) are that plug, (8) for electrode contact, (9) insulation sleeve, (10) for electrode spring, (11) for electrode, (12) for felt pad, (13) be valve body drive link, (14) for medicinal liquid switch turn round, (15) for battery, (16) for sleeve, (17) be laryngoscope blade for return spring, (6) for nut, (7) for medicinal liquid control valve spool, (5) for medicinal liquid control valve valve body, (4).
Embodiment one (see figure 1):
This laryngoscope is by medicine storing pot (1), sealing ring (2), medicinal liquid control valve valve body (3), medicinal liquid control valve spool (4), return spring (5), for nut (6), plug (7), electrode contact (8), insulation sleeve (9), electrode spring (10), electrode (11), felt pad (12), valve body drive link (13), medicinal liquid switch are turned round (14), battery (15), sleeve (16), laryngoscope blade (17) constitutes; The interior glaze pipe of medicine storing pot (1) links with medicinal liquid control valve valve body (3), and a sealing ring (2) is arranged therebetween, and medicinal liquid control valve spool (4) and return spring (5) are loaded in the medicinal liquid control valve valve body; Battery (15), electrode (11), electrode contact (8), electrode spring (10) are housed in the sleeve (16), and fix by its underpart by plug (7) and insulation sleeve (9); Valve body drive link (13) passes the hole on sleeve (16) wall and the electrode (11), and the one end withstands on the inwall of sleeve (16), and the other end withstands on the tail end of medicinal liquid control valve spool (4); The medicinal liquid switch is turned round (14) and is penetrated from the hole on sleeve (16) wall, is inserted in the valve body drive link (13); The relative position of medicine storing pot (1) and sleeve (16) is fixed by a box body (seeing the double dot dash line among the figure) and nut (6), plug (7); Laryngoscope working head (17) be loaded on medicinal liquid control valve valve body (3) and plug (7) below.Spool drive link (13) is made by insulant or is handled or add insulation sleeve through surface insulation.Have a cannelure on the medicinal liquid control valve spool (4), medicinal liquid is flow through.
Power supply one utmost point of this laryngoscope is drawn by electrode (11), electrode spring (10) and electrode contact (8), and another is shell very.The control medicinal liquid only needs to refer to that with little mother light pressing liquid switch turns round (14) that make medicinal liquid control valve spool (4) move by spool drive link (13), the groove on it is aimed at the hole on the medicinal liquid control valve valve body, and medicinal liquid can flow out.
Claims (2)
1, this utility model is a kind of laryngoscope, the device and operation or the diagnosis auxiliary facilities that relate to the chamber of checking human body or pipe, it is by medicine storing pot, sealing ring, medicinal liquid control valve valve body, medicinal liquid control valve spool, return spring, for nut, plug, electrode contact, insulation sleeve, electrode spring, electrode, felt pad, valve body drive link, medicinal liquid switch are turned round, battery, sleeve, laryngoscope blade constitute, and it is characterized in that:
Glaze pipe in a, the medicine storing pot links with medicinal liquid control valve valve body, and a sealing ring is arranged therebetween, and medicinal liquid control valve spool and return spring are loaded in the medicinal liquid control valve valve body;
Battery, electrode, electrode contact, electrode spring are housed in b, the sleeve, and fix by its underpart by plug and insulation sleeve;
C, valve body drive link pass the hole on sleeve wall and the electrode, and the one end withstands on the telescopic inwall, and the other end withstands on the tail end of medicinal liquid control valve spool;
The hole that d, medicinal liquid switch are turned round on the sleeve wall penetrates, and is inserted in the valve body drive link;
E, medicine storing pot and telescopic relative position are fixed by a box body and nut, plug;
F, laryngoscope blade be loaded on medicinal liquid control valve valve body and plug below.
2, laryngoscope according to claim 1 is characterized in that the spool drive link is made by insulant or handles or add insulation sleeve through surface insulation.
