4, moving before and after the main control system mechanism reaches the photoelectric limit switch that freezing head moves up and down, and is positioned at outside the refrigerating chamber, and this structure failure rate is little, easy to maintenance, and stroke is accurate up and down before and after can guaranteeing.
5, refrigerating effect is splendid
1. microtome all weather operations in 24 hours remained permanent cold cut sheet state in 1 year 360 days.
2. have quick frozen section function, can carry out frozen section in 10 minutes-20 minutes from starting shooting.
3. chipping qualities is superior, section is flat thin.
Saving grace and advantage that the present invention compares with general cryostat are:
1, mesa structure: small and exquisite, perfect in shape and function is applicable to hospitals at different levels, R﹠D institution.More be applicable to the equipment ambulance, Physical examination car, field hospital etc.
2, fast-refrigerating: have the existing refrigerating function of domestic and international cryostat, can 24 hours continuous permanent freezing microtome sections, 1 year 360 days (must be start in 360 days when keeping the freezing microtome section function, otherwise shutting down back second day again start to reach the cold cut sheet time oversize, reach best chilling temperature, because of the environment difference, generally need 40-to 44 hour), increasing crucial one is fast freezing function, said promptly counting from the on time fast reaches the required time weak point of section chilling temperature, need 6-20 minute generally speaking, shifted to an earlier date 50%-70% than traditional cryostat time.
3, desk-type totally-closed snap frozen microtome is multiple functional:
1. two limit switches are installed in outside the refrigerating chamber, are connected with section main frame mechanism in the refrigerating chamber, and the centre is provided with heat-insulation layer.
2. stepper motor is installed in that refrigerating chamber is outer to be connected with microtome in the refrigerating chamber, and there is heat-insulation layer the connected mode special shaft joint centre of extending.
3. the section main frame mechanism that driving mechanism is installed in outside the refrigerating chamber and refrigerating chamber is interior is connected, and drives freezing head and advances, retreats and finish the section function, and its advantage is: 1, convenient for maintaining; 2, if above electrical part is placed on freezing indoor temperature and changes repeatedly, fragile; 3, above electrical part is installed in refrigerating chamber and is not prone to quality problems outward, has increased mechanical stability against short circuit, safe and effective work.
4, the sliding dust cover is installed; Elegant in appearance and practical, slag, foreign material enter main frame when preventing to cut into slices, and have overcome like product and have used the very easily aging problem of rubber, can need not change parts all the life.
5, main frame mechanism adopts new components: main frame mechanism has adopted the linear roller bearing, thus can be freely about, move forward and backward, finish slicing processes.
6, have automatic anti-frosting function: the visual window on the refrigerating chamber is the sliding door glass structure, and the wind of being sent by blower fan has been realized automatic frost prevention from surperficial without stop the blowing of sliding door glass.
The present invention is skillfully constructed, reasonable in design, simple to operation, performance is complete and reliable and stable, suitable medical research department and hospital use.
Need to prove: under the prerequisite that does not change the principle of the invention and design, change of having done or distortion all belong to protection scope of the present invention.
