A kind of small-sized percussion device that causes injury of laboratory animal of the present invention, the column, the end that comprise rectangular platform, are vertically connected on the rectangular platform edge are connected at first horizontal stand on column top, it is characterized in that:
One vertically downward last guide and the other end of first horizontal stand be connected, a bump head is located in the upper end of guide; One lateral pin passes the hole of guide one sidewall, the hole of a bump shank and the hole of last another sidewall of guide successively is positioned in the guide bump head;
One vertically downward the top of following guide is enclosed within the outside, bottom of guide, and an end of the middle part of following guide and second horizontal stand is connected, and the other end of second horizontal stand and the middle and lower part of column are connected.
Described a kind of small-sized percussion device that causes injury of laboratory animal also comprises the wooden platform that contacts with ground across four feet on rectangular platform.
Described a kind of small-sized percussion device that causes injury of laboratory animal, its described bump head is a fabricated structure, forms by the semicircle ball of a band shank with the nut that shank threads is connected; On the shank between semicircle ball and the nut, be provided with 0 or be provided with a slice quality adjustment ring at least.Like this, just can regulate the quality of bump head easily according to the experiment needs.
Described a kind of small-sized percussion device that causes injury of laboratory animal, cooperation position of the guide and first horizontal stand can up-down adjustment on it; The cooperation position of the following guide and second horizontal stand also can up-down adjustment.
Described a kind of small-sized percussion device that causes injury of laboratory animal, the cooperation position of its described first horizontal stand and second horizontal stand and column can up-down adjustment.
The present invention compares with prior art and has the following advantages:
(1) compact conformation, light, the structure of combination type bump head can load arbitrarily or off-load, qualitative data is reliable, have easy and simple to handle, physical parameter is easy to control, impact site accurately reaches advantages such as favorable repeatability;
(2), can carry out forward bump and lateral impact respectively as rabbit, rat and mice to the experiment toy.Pathology, type, the traumatic condition and clinical comparatively approaching of damage internal organs;
(3) the bump head can cause fracture of skull, brain contusion, intracranial hemorrhage etc.; Chest can cause the damage of fracture of rib, the heart, lung; The bump abdominal part when causing hepar damnification, can merge have the inclination, the damage of lung, kidney; The bump extremity can cause dissimilar fracture, can fully satisfy the needs of impact injury experimentation.
(4) can on the model of causing injury, carry out the detection of mechanics factor analysis and multinomial experimental index.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the structural representation of combination type bump head.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2 and a kind of small-sized percussion device that causes injury of laboratory animal shown in Figure 3, the column 2, the end that comprise rectangular platform 1, are vertically connected on the rectangular platform edge are connected at first horizontal stand 3 on column top;
One vertically downward last guide 4 and the other end of first horizontal stand 3 be connected, a bump 5 is located in the upper end of guide 4; The hole that one lateral pin 6 passes hole, the bump hole of a shank and last another sidewall of guide of guide one sidewall successively makes clashes into 5 and is positioned in the guide 4;
One vertically downward the top of following guide 7 is enclosed within the outside, bottom of guide 4, and an end of the middle part of following guide 4 and second horizontal stand 8 is connected, and the middle and lower part of the other end of second horizontal stand and column 2 is connected;
Also comprise the wooden platform 9 that contacts with ground across four feet on rectangular platform 1.
Described bump 5 is a fabricated structure, forms by the semicircle ball 5-1 of a band shank with nut 5-2 that shank threads is connected; On the shank between semicircle ball and the nut, be provided with 0 or be provided with a slice quality adjustment ring 10 at least.Like this, just can regulate the quality of bump head easily according to the experiment needs.
