Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As depicted in figs. 1 and 2, anesthetic gases of the present invention reclaims face shield experimental provision and comprises an outer shroud, and this outer shroud is the face shield of an opposing seal on face for covering on animal and nose, and it can be anaesthetic mask for animal of the prior art.Shroud internal fixtion has one to reclaim cover 1 outside, and reclaiming cover 1 is a cube, on the downside of the rear portion of reclaiming cover 1, be provided with a table top stretched out; Reclaim in cover 1 and be provided with cavity 6, this cavity 6 be arranged on the cavity mouth 5 reclaiming cover 1 front end face and be communicated with, cavity 6 is a rectangle, the left surface reclaiming cover 1 has the air inlet connecting oral pore 16 of the circle through with cavity 6, the upper end of reclaiming cover 1 is then provided with the block slots 10 be communicated with cavity 6, block slots 10 arranges along the depth direction of cavity 6, extends to the rear portion (namely reclaiming the rear end of cover 1) of cavity 6 from the accent of cavity 6 always.The shape of block slots 10 is rectangle.
Cubical face shield block 2 is provided with in cavity 6, the width of the external height of this face shield block 2 and width and cavity 6 and highly equal, the length of face shield block 2 is less than the degree of depth of cavity 6, thus make between face shield block 2 and cavity 6, to form a gas recycling cavity 20, the right side of gas recycling cavity 20 is provided with the gas be tightly connected with it and gives vent to anger interface 11, and gas interface 11 of giving vent to anger is connected with outside gas recovery device of the prior art.
Face shield block 2 is provided with the inlet chamber 7 arranged along face shield block 2 length direction, and this inlet chamber 7 is conical to adapt to the animal nose of different size.The front end face of face shield block 2 is provided with the opening be communicated with inlet chamber 7, the lower surface of inlet chamber 7 is provided with the ratch groove 15 of the rectangle arranged along face shield block 2 length direction, the axis of ratch groove 15 is mutually vertical with the axis of inlet chamber 7, lower end edge inlet chamber 7 depth direction of inlet chamber 7 is provided with tooth fixing port 8, inlet chamber 7 is communicated with ratch groove 15 by this tooth fixing port 8, ratch groove 15 is provided with animal and fixes ratch 9, the left and right sidewall at two ends, left and right and ratch groove 15 that animal fixes ratch 9 is fixedly connected with.Ratch groove 15 is arranged on the orifice edge place near inlet chamber 7, and the left side of face shield block 2 is provided with the gas inlet interface 19 be communicated with inlet chamber 7, and gas inlet interface 19 stretches out and reclaims outside cover 1 from air inlet connecting oral pore 16, and is connected with the anesthetic gases device of outside.
Briquetting 3 is provided with in the upper end of face shield block 2, block slots 10, briquetting 3 is made up of briquetting seat 31 and the pressure head 32 being arranged on briquetting seat 31 front end, briquetting seat 31 and pressure head 32 vertical setting mutually, profile and the size of the profile of briquetting seat 31 and size and block slots 10 are suitable, when briquetting seat 31 is arranged on face shield block 2, pressure head 32 is suspended on outside the aperture, front end of inlet chamber 7, and can stop the aperture area of inlet chamber 7 thus pushed down by animal nose by selectivity.
Between briquetting 3 with face shield block 2 by be arranged on face shield block 2 upper end screw rod 12, be connected with the governor motion that the adjustment cap 13 that screw rod 12 is threaded forms, screw hole 14 is provided with on briquetting seat 31, with corresponding section, screw rod 12 position, briquetting seat 1 is enclosed within screw rod 12 by screw hole 14, thus is arranged on actively on face shield block 2.The lower surface of pressure head 32 is provided with cambered surface 33.
As shown in Figure 3, sealing ring is provided with between gas inlet interface 19 and face shield block 2 to reach the requirement be tightly connected.The width of ratch groove 15 is equal with the orifice diameter of inlet chamber 7.
As shown in Figure 4, the rear end of block slots 10, the bottom of cavity 6 are provided with column 17, and rear end and the corresponding section, column 17 position of briquetting seat 31 are provided with leghole 18, and column 17 inserts in leghole 18, thus is limited in block slots 10 by briquetting 3.
The width of block slots 10 is less than the width of cavity 6, and gas interface 11 of giving vent to anger is provided with sealing ring, thus realizes gas outlet 11 and reclaim between cover 1 realizing being tightly connected.
During use, first fix on ratch 9 by the tooth of the animal animal hung on face shield block 2, the nose pushing down animal with the pressure head 32 of briquetting 3 makes animal head rock; Then entered by gas inlet interface 19 on face shield block 2 by anesthetic gases in the inlet chamber 7 of face shield block 2 and anaesthetize animal, the gas leaked by animal mouth in anaesthesia process enters gas concentration unit via the interface 11 of giving vent to anger of the gas on gas recycling cavity 20.
The present invention ensures head stability in an experiment by designing independently front tooth fixture; By gas access and gas outlet are separated, the flow direction of such anesthetic gases is introduced into the nostril of animal from entrance, the negative pressure that gas overflowing part is then produced by the gentle body recover of the outer shroud of relative closure and anesthetic gases is discharged from gas interface of giving vent to anger, prevents from overflowing and causes experimenter absorb the anesthetic gases of spilling and produce injury to human body.
