The specific embodiment
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 the face shield experimental provision and comprises an outer shroud, and this outer shroud is face for covering on animal and a relative face shield sealed on nose, and it can be anaesthetic mask for animal of the prior art.Be fixed with outside one in shroud and reclaim cover 1, reclaiming cover 1 is a cube, at the rear portion downside that reclaims cover 1, is provided with a table top stretched out; Reclaim in cover 1 and be provided with cavity 6, this cavity 6 is communicated with the cavity mouth 5 that is arranged on recovery cover 1 front end face, cavity 6 is a rectangle, have the air inlet connecting oral pore 16 of the circle connected with cavity 6 on the left surface that reclaims cover 1, the upper end of reclaiming cover 1 is provided with the block slots 10 be communicated with cavity 6, block slots 10 is the depth direction settings along cavity 6, extends to the rear portion (reclaiming the rear end of cover 1) of cavity 6 from the accent of cavity 6 always.Block slots 10 be shaped as rectangle.
Be provided with cubical face shield piece 2 in cavity 6, the external height of this face shield piece 2 and width are with the width of cavity 6 and highly equate, the length of face shield piece 2 is less than the degree of depth of cavity 6, thereby make between face shield piece 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 interface 11 of giving vent to anger, and the gas interface 11 of giving vent to anger is connected with outside gas recovery device of the prior art.
Face shield piece 2 is provided with the inlet chamber 7 arranged along face shield piece 2 length directions, and this inlet chamber 7 is conical to adapt to the animal noses of different sizes.The front end face of face shield piece 2 is provided with the opening be communicated with inlet chamber 7, be provided with the ratch groove 15 of the rectangle arranged along face shield piece 2 length directions on the lower surface of inlet chamber 7, the axis of ratch groove 15 is mutually vertical with the axis of inlet chamber 7, lower end edge inlet chamber 7 depth directions of inlet chamber 7 are provided with tooth fixing port 8, this tooth fixing port 8 is communicated with inlet chamber 7 with ratch groove 15, be provided with fixedly ratch 9 of animal on ratch groove 15, the animal fixedly two ends, left and right of ratch 9 is fixedly connected with the left and right sidewall of ratch groove 15.Ratch groove 15 is arranged on the orifice edge place near inlet chamber 7, and the left side of face shield piece 2 is provided with the gas intake interface 19 be communicated with inlet chamber 7, and gas intake interface 19 stretches out and reclaims outside cover 1 from air inlet connecting oral pore 16, and is connected with outside anesthetic gases device.
Be provided with briquetting 3 in the upper end of face shield piece 2, block slots 10, briquetting 3 is comprised of briquetting seat 31 and the pressure head 32 that is arranged on briquetting seat 31 front ends, briquetting seat 31 and the mutual vertical setting of pressure head 32, 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 piece 2, pressure head 32 is suspended on outside the front end aperture of inlet chamber 7, thereby and can selectivity stops that the aperture area of inlet chamber 7 pushes down the animal nose.
The governor motion that screw rod 12 by being arranged on face shield piece 2 upper ends between briquetting 3 and face shield piece 2, the adjusting cap 13 be threaded with screw rod 12 form is connected, on briquetting seat 31, with screw rod 12 corresponding sections, position be provided with screw hole 14, briquetting seat 1 is enclosed within on screw rod 12 by screw hole 14, thereby is arranged on actively on face shield piece 2.Be provided with cambered surface 33 on the lower surface of pressure head 32.
As shown in Figure 3, be provided with sealing ring between gas intake interface 19 and face shield piece 2 to reach the requirement be tightly connected.The width of ratch groove 15 equates with the orifice diameter of inlet chamber 7.
As shown in Figure 4, the bottom of the rear end of block slots 10, cavity 6 is provided with column 17, and the rear end of briquetting seat 31 and column 17 corresponding sections, position are provided with leghole 18, and column 17 inserts in leghole 18, thereby briquetting 3 is limited in block slots 10.
The width of block slots 10 is less than the width of cavity 6, and the gas interface 11 of giving vent to anger is provided with sealing ring, thereby realizes gas outlet 11 and reclaim between cover 1 and realize being tightly connected.
During use, at first the tooth of animal is hung over to animal on face shield piece 2 fixedly on ratch 9, the nose of pushing down animal with the pressure head 32 of briquetting 3 can't rock the animal head; Then anesthetic gases is entered by gas intake interface 19 on face shield piece 2 in the inlet chamber 7 of face shield piece 2 animal is anaesthetized, the gas leaked by the 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 guarantees the stability of head in experiment by designing independently front tooth fixture; By gas access and gas outlet are separated, the flow direction of anesthetic gases is to be introduced into the nostril of animal from entrance like this, the negative pressure that gas overflowing part produces by the gentle body recover of the outer shroud of relative closure makes anesthetic gases discharge from the gas interface of giving vent to anger, and prevents from overflowing the anesthetic gases that causes the experimenter to absorb overflowing and human body is produced to injury.
