Abstract
The invention discloses a mouth opening device. The mouth opening device comprises a handheld rod, an upper mandible fixing chain, a fixing hook and a lower mandible fixing ring; and a stomach tube insertion hole is formed in the axial middle of the handheld rod, the lower mandible fixing ring is located in the axial middle of the handheld rod and on the lateral face of the stomach tube insertion hole, the upper mandible fixing chain and the fixing hook are located on the side, opposite to side with the lower mandible fixing ring, of the handheld rod, and the fixing positions of the upper mandible fixing chain and the fixing hook are symmetrical with the stomach tube insertion hole as the axis. The mouth opening device is simple in structure and convenient to manufacture; and generally, only two persons are needed for operation, so that the mouth opening device has the beneficial effects of being easy and convenient to operate, safe and practical, wasting no medicine, and saving time and labor. Through the design of an external hole section, rapider and more convenient stomach tube insertion is guaranteed, and through the design of an internal hole section, a more stable and more accurate inserted stomach tube is guaranteed.
Description
Technical field
The present invention relates to veterinary medical instrument manufacturing technology field, especially a kind of gag.
Background technology
Gastric infusion is one of dose regimen that pig is conventional, is mainly used in the administration of oral liquid, tablet, powder, granule, pill, especially the administration such as Chinese powder medicine, oral liquid of palatability difference.The method of gastric infusion mainly adopts the direct perfusion method in free-hand Baoding and stomach tube perfusion method, stomach tube perfusion method can realize dosed administration, generally by medicine furnishing scattered paste shape or liquid by stomach tube administration, but because the wing of nose of pig and upper labial commissure form muzzle, the upper and lower nose clip of nasal cavity and nasal septum passage extremely narrow, be difficult to by nasal feeding tube administration, the gavage method administration adopting per os to enter stomach, gag is then the required utensil of pig administration more.At present, conventional method is direct drug injection bottle or the perfusion of medicine spoon, or using small wooden traverse in the oral cavity of pig as gag perfusion, or utilize the gag of other animal to open oral cavity perfusion, these methods very easily cause pig oral injury, medicinal liquid enters trachea and foreign body pneumonia also can be caused even dead, not only cannot realize dosed administration, and drug waste is large.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of gag is proposed, structure is simple, easy to make, easy and simple to handle, safe, practical, do not waste medicine, save time, laborsaving, more fast and easily stomach tube being inserted by ensure that the design of exit orifice section, the design of endoporus section, ensureing that the stomach tube after inserting is comparatively stable and accurately.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of gag, comprises hand-holding rod, the upper jaw fixes chain, fixation hook and lower jaw retainer ring,
Stomach tube jack is had in the axial centre position of described hand-holding rod,
Described lower jaw retainer ring is positioned at the middle part of described hand-holding rod axis, the side of described stomach tube jack,
The described upper jaw is fixed chain and is positioned at side contrary with described lower jaw retainer ring on described hand-holding rod with described fixation hook, and the described upper jaw fixes chain and described fixation hook fixed position with described stomach tube jack for axial symmetry,
Described jack comprises exit orifice section 21 and endoporus section 22, described exit orifice section and described endoporus section are truncated cone-shaped, the minimum end face of diameter of described exit orifice section is connected with the largest diameter end face of described endoporus section, the largest diameter end face of described exit orifice section and the minimum end face of described endoporus section diameter lay respectively at the both sides of described hand-holding rod
During use, stomach tube inserts from described exit orifice section side.
Further, described lower jaw retainer ring is semicircle.
Further, the described upper jaw is fixed chain and is formed by connecting by some circuluses.
A kind of gag of the present invention, structure is simple, easy to make, generally only needs two people to operate, have easy and simple to handle, safe, practical, do not waste medicine, save time, labour-saving feature.More fast and easily stomach tube being inserted by ensure that the design of exit orifice section, the design of endoporus section, ensureing that the stomach tube after inserting is comparatively stable and accurately.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of gag of the present invention;
Fig. 2 is the cross-sectional schematic at a kind of gag jack place of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of gag as illustrated in fig. 1 and 2, comprises hand-holding rod 1, the upper jaw fixes chain 3, fixation hook 4 and lower jaw retainer ring 5,
Have stomach tube jack 2 in the axial centre position of hand-holding rod 1, this stomach tube jack 2 is through hole,
Lower jaw retainer ring 5 is positioned at the middle part of hand-holding rod 1 axis, the side of stomach tube jack 2,
The upper jaw is fixed chain 3 and is positioned at the contrary side of hand-holding rod 1 up and down jaw retainer ring 5 with fixation hook 4, the upper jaw fix chain 3 with fixation hook 4 fixed position with stomach tube jack 2 for axial symmetry, the axes normal of the plane that the fixed position that the upper jaw fixes chain 3, fixation hook 4 and lower jaw retainer ring 5 is formed and stomach tube jack 2
Described jack comprises exit orifice section 21 and endoporus section 22, described exit orifice section and described endoporus section are truncated cone-shaped, the minimum end face of diameter of described exit orifice section is connected with the largest diameter end face of described endoporus section, the largest diameter end face of described exit orifice section and the minimum end face of described endoporus section diameter lay respectively at the both sides of described hand-holding rod
During use, stomach tube inserts from described exit orifice section side.
Lower jaw retainer ring 5 is semicircle.
The upper jaw is fixed chain 3 and is formed by connecting by some circuluses.
Concrete dimensions of the present invention and making material can carry out different designs according to actual needs, and in the present embodiment, hand-holding rod 1 is cylindrical, long 30-40cm, cross-sectional diameter 2-3cm; Stomach tube jack 2 aperture 0.5-0.8cm; All components are made by hard metal.
During use, two people respectively catch an ear of pig, standing restraint, wherein a staff takes one end of hand-holding rod 1, the side of chain 3 is fixed upwards with the upper jaw, with the lip friction pig of the middle part of hand-holding rod 1, when pig yelps lips, take advantage of a situation hand-holding rod 1 traverse in pig oral cavity, and make stomach tube jack 2 direction consistent with pig body direction, lower jaw retainer ring 5 is enclosed within pig lower jaw, when stomach tube jack 2 and pharynx are alignd substantially, the upper jaw is fixed chain 3 and be hooked on fixation hook 4 on the pig upper jaw, stomach tube is inserted oral cavity through stomach tube jack 2, when stomach tube is inserted to pharyngeal, twitch stomach tube back and forth to swallow to stimulate pig, when stomach tube by pharyngeal enter esophagus after, slowly stomach tube is inserted gastric.Judge that stomach tube accurately inserts gastric, can perfusion be carried out.
A kind of gag of the present invention, structure is simple, easy to make, generally only needs two people to operate, have easy and simple to handle, safe, practical, do not waste medicine, save time, labour-saving feature, avoid in perfusion process the damage that pig is caused.More fast and easily stomach tube being inserted by ensure that the design of exit orifice section, the design of endoporus section, ensureing that the stomach tube after inserting is comparatively stable and accurately.
