Abstract
The invention discloses a mouth gag. The mouth gag comprises a supporting base and a threaded rod. L-shaped supporting arms are hinged to the two ends of the supporting base and sleeved with protective sleeves in a matched mode, the mouth gag further comprises nuts in threaded fit with the tail ends of the L-shaped supporting arms, trays are installed on the nuts, and when the L-shaped supporting arms are placed in the oral cavity of a patient, the two trays are arranged to make contact with the upper jaw and the lower jaw of the patient respectively. When the L-shaped supporting arms are taken out of the protective sleeves, after the nuts are in threaded fit with the tail ends of the L-shaped supporting arms, the trays are fixed to the tail ends of the L-shaped supporting arms; when the L-shaped supporting arms stretch deep into the oral cavity of the patient, the trays make direct contact with the upper jaw or the lower jaw of the patient, and the contact area between the L-shaped supporting arms and the upper jaw or the lower jaw of the patient is increased, so that stress, acting inside the oral cavity, of the L-shaped supporting arms is dispersed to reduce the pressure, borne by the oral cavity of the patient, of the L-shaped supporting arms, and the post-operation sequelae of the patient are reduced.
Description
Technical field
The present invention relates to a kind of medical first aid equipment, specifically refer to gag.
Background technology
Gag, also known as mouth-gag, is the apparatus strutting oral cavity when needing gastric lavage etc. for dyspnea or obnubilation.Gag body is in " U " shape, and two ends of gag body are connected with a handle respectively.Gag body has elasticity, and two side arms of gag body can bend when being subject to the compressing by ambient pressure in the inside of gag body or outside, and when external pressure disappears, two side arms of gag body return to original position again.
The side arm of existing gag is very sharp, easily scratch user or patient in use, and need before use to carry out disinfection to the sidewall of gag, namely in disinfectant solution, certain hour is soaked, to prevent patient infection, but must step and in use to the expansion in patient oral cavity just because of this, greatly have impact on first aid efficiency, and then cause patient to lose best relief chance.
Summary of the invention
The object of the present invention is to provide gag, facilitate the quick use of gag, and then reach and shorten first aid time and improve the object of relief rate.
Object of the present invention is achieved through the following technical solutions:
Gag, comprise supporting seat and run through the screw rod of the supporting seat taper of threaded engagement with it, L shape support arm is hinged with at the two ends of described supporting seat, one end of screw rod is fixed with swivel head, the other end of screw rod is placed between two L shape support arms, both sides away from screw rod one side are provided with projection to described L shape support arm, described L shape support arm is arranged with the protective sleeve of coupling mutually with it, the inwall of protective sleeve is fixed with two crimpings be oppositely arranged, gap is left between the movable end of two described crimpings, described L shape support arm is provided with gag lever post, and when L shape support arm is placed in protective sleeve, gag lever post is through gap and two crimping matched in clearance, also comprise the nut coordinated with the end thread of L shape support arm, described nut is provided with pallet, when L shape support arm puts into patient oral cavity, the position of two pallets is configured to, and two pallets contact with the maxillary of patient, lower jaw respectively.When the present invention uses, by the protection of protective sleeve to L shape support arm, L shape support arm can be effectively avoided to cause its sharp keen end to scratch user, to overcome the deficiency of existing gag because of operate miss; During work, by regulating swivel head, screw rod is moved on supporting seat, until the movable end of screw rod moves on two L shape support arms, wherein screw rod is tapered and one end that its external diameter is little is movable end, by the movable end of screw rod to the expansion of spacing between two L shape support arms, make the expansion that L shape support arm realizes patient oral cavity, convenient first aid is carried out to patient; When L shape support arm takes out from protective sleeve, after nut and threaded engagement, pallet is made to be fixed on the end of L shape support arm, when L shape support arm gos deep into patient's cavity interior, pallet, directly with the maxillary of patient or lower jaw directly contacts, increases the contact area between L shape support arm and patient's maxillary or lower jaw, makes L shape support arm be applied to stress dispersion in oral cavity, to reduce L shape support arm to the constriction in patient oral cavity, reduce patient's sequela after surgery;
Wherein, the inwall of protective sleeve is provided with two crimpings be oppositely arranged; and on L shape support arm, be fixed with the gag lever post that two crimpings match; by the matched in clearance between gag lever post and two crimpings; L shape support arm and protective sleeve is made to remain close contact; namely ensure part clean hygiene L shape support arm going deep into patient oral cavity, reduce the infection rate of patient.
Further, described swivel head is circular or oval.As preferably, swivel head adopts circular or oval structure, the PROPEL of person's hand easy to use when making to expand patients mouth, avoids using brute-force that the gap between two L shape support arms is increased, to reduce the probability in accidental injury patient oral cavity.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention is when L shape support arm takes out from protective sleeve, after nut and threaded engagement, pallet is made to be fixed on the end of L shape support arm, when L shape support arm gos deep into patient's cavity interior, pallet, directly with the maxillary of patient or lower jaw directly contacts, increases the contact area between L shape support arm and patient's maxillary or lower jaw, makes L shape support arm be applied to stress dispersion in oral cavity, to reduce L shape support arm to the constriction in patient oral cavity, reduce patient's sequela after surgery;
2, swivel head of the present invention adopts circular or oval structure, the PROPEL of person's hand easy to use when making to expand patients mouth, avoids using brute-force that the gap between two L shape support arms is increased, to reduce the probability of accidentally injuring patient oral cavity.
