Embodiment 1

[0040] When using the existing impact device to damage the brains of experimental animals, due to the different sizes of the experimental animals, after placing the experimental animals on the base of the device, small animals of different physiques will collide with the end of the impact column. The distance between them is not the same, so that when the impact force of the impact column is fixed, the impact force on the brains of test animals with different physiques will be different, and it is impossible to accurately adjust the impact test according to the experimental requirements according to the physique of the test animals. The strength of the animal's brain will directly affect the accuracy of the later experimental results; and when the above device is in use, the impact column is driven to move down and hit the experimental animal's brain through the impact block hitting the fixed block, thereby giving the impact of the impact column When the force increases, the li...

Embodiment 2

[0062] The difference between Embodiment 2 and Embodiment 1 lies in that an auxiliary adjustment mechanism is provided in the frame between the animal fixing seat and the impact test seat.

[0063] Such as Figure 11 with Figure 12 As shown, the frame between the animal fixing seat and the impact test seat is provided with an adjustment auxiliary mechanism 11, and the adjustment auxiliary mechanism includes a sliding sleeve 111, an adjustment sleeve 112 and an adjustment ruler 113, and the top of the fixed shaft 44 extends forward. The bearing seat 43 is rotatably fixed on the frame between the animal fixed seat and the impact test seat, and the sliding bushing 111 is matched and set on the fixed shaft 44 between the animal fixed seat and the impact test seat, and can be moved forward and backward along the fixed shaft 44 Sliding, one end of the sliding sleeve 111 is provided with a threaded hole communicating with the interior along the radial direction, and is matched with...

Embodiment 3

[0066] The difference between embodiment 3 and embodiment 2 lies in the structure of the locking parts.

[0067] Such as Figure 13 Said, the locking part comprises a position sensor 694, a controller, an adjusting motor 691, an adjusting screw 692 and a driving wire block 693, and the adjusting motor 691 is axially fixed on the outer wall of the front end of the limit slide 61, and is connected with the controller The control is connected, and the motor shaft of the adjusting motor 961 is set backward, and the adjusting screw rod 692 is arranged on the rear side of the adjusting motor 961 along the axial direction, and is connected with the motor shaft of the adjusting motor, and the middle part of the driving wire block 693 is axially It is provided with a threaded hole suitable for the adjustment screw rod, and is matched with the adjustment screw rod 693 on the rear side of the limit slide cylinder. The end of the drive wire block 693 adjacent to the impact cylinder is pro...

Abstract

The invention discloses an impact device for animal neurocranium injury, which comprises a rack and a display device, the rack is provided with an animal fixing seat, an impact test seat, an impactor fixing seat, a support frame and an impactor, and the animal fixing seat and the impact test seat are longitudinally mounted on the rack at an interval; a pressure sensor connected with the display device is arranged on the impact test seat; the impactor fixing seat comprises a bottom plate fixed on the rear side rack between the animal fixing seat and the impact test seat, and a fixed roller is rotationally fixed on the bottom plate in the transverse direction; the device is unique in structure and convenient to use, the problem that an existing impact device cannot accurately adjust the impact force borne by the neurocranium of an experimental animal according to the physique size of the experimental animal is effectively solved, and the problems that the existing impact device is single in applicability, and the impact depth cannot be controlled while the impact force is adjusted are effectively solved.

Description

technical field [0001] The invention belongs to the field of animal experiment equipment, and in particular relates to an impact device for animal brain injury. Background technique [0002] Traumatic brain injury has a very high mortality and disability rate, which brings heavy burden and injury to society and family. In order to propose a better treatment plan, people need to accumulate the pathological understanding of traumatic brain injury through a large number of animal brain impact experiments. Traditionally, when conducting biological impact experiments in laboratories, BIM-I biological impact machines are generally used. However, due to the large size of the impact test equipment, it is only suitable for large animals such as cattle, pigs, and sheep. [0003] The inspection institute found a Chinese patent document with the announcement number "CN107736947B". This patent discloses an impact device for causing brain injury in animals in a wake-up test. A base is p...
