Problems solved by technology

However, there is still no effective device to measure the stress on the brain tissue around the hematoma.
At present, there is still controversy about whether cerebral hemorrhage should be treated with surgery in clinical practice.

Embodiment 1

[0029] Embodiment 1: as figure 1 and Figure 5 As shown, an animal intracranial stress detection device includes a fixing device 1 for fixing the animal and a measuring device 2 for measuring the intracranial pressure of the animal. The measuring device 2 includes a pressure measuring gauge 20, a syringe 21 and a pressure device 22 connected to the intracranial of the animal. Two horizontally facing outlets 23 are arranged at the front end of the syringe 21, and one of the outlets 23 is connected to the The pressure measuring gauge 20, another outlet 23 is connected to the pressure applying device 22. Wherein, the pressure applying device 22 includes a catheter 24, one end of the catheter 24 is connected to the outlet 23 of the syringe 21, and the other end of the catheter 24 is provided with a balloon 25 placed in the animal's skull. The balloon 25 is fixedly connected to the skull of the animal. And a depth indicator line 28 is provided on the catheter at the upper end of...

Embodiment 2

[0033] Embodiment 2: as Figure 2-5 As shown, an animal intracranial stress detection device includes a fixation device 1 for fixing the animal and a measuring device 2 for measuring the intracranial pressure of the animal. The measuring device 2 includes a pressure measuring gauge 20, a syringe 21 and a connecting animal The intracranial pressure applying device 22 is provided with two horizontally facing outlets 23 at the front end of the syringe 21 , and one of the outlets 23 is connected to the pressure measuring gauge 20 through a catheter (length: 40mm). Another outlet 23 is connected to the pressure applying device through a connecting pipe 26, and the pressure applying device includes a conduit 24, one end of the conduit 24 is connected with the connecting pipe 26, and the other end of the conduit 24 is provided with a An intracranial balloon 25, said balloon 25 is fixedly connected on the animal skull (around the hematoma), and a depth indicator line 28 is arranged on t...

Embodiment 3

[0039] Embodiment 3: as Figure 6 and Figure 7 As shown, this embodiment is an improvement on the fixing device 1 on the basis of Embodiment 1 and Embodiment 2. In this embodiment, the fixing device 1 includes a cylinder 10, a head baffle 11 and a tail The baffle plate 12 is provided with an axial chute 14 on the cylinder 10, the chute 14 has an opening at one end and a closed end at the other end, a fixer 15 is provided on the head baffle, and the The head baffle 11 is put in from the end of the cylinder 10, the fixer 15 is exposed through the chute 14, and slides into the interior of the cylinder 10 through the chute 14 until it is put into the chute 14. Close the end, then put the animal to be detected into the cylinder 10, and finally put the tail baffle 12 with the holder 15 into the cylinder 10 in the same way.

[0040] In addition, an opening 13 capable of exposing the tail of the animal is also provided on the tail baffle 12 , so that it is convenient to perform mer...

Abstract

The present invention provides a stress detection device used around the intracranial hematoma of SD rats, comprising a fixation device 1 for fixing the animal and a measuring device 2 for measuring the intracranial stress of the animal, and the measuring device 2 includes a pressure The measuring gauge 20, the syringe 21 and the pressure applying device 22 connected to the animal's cranium are provided with at least two horizontally facing outlets 23 at the front end of the syringe 21, one of which is connected to the pressure measuring gauge 20, and the other The outlet 23 is connected to the pressure applying device 22 . The animal intracranial detection device of the present invention can accurately detect the stress around the animal intracranial hematoma.

Description

technical field [0001] The invention relates to an animal intracranial stress detection device, in particular to a stress detection device used around animal intracranial hematoma. Background technique [0002] In the acute stage of cerebral hemorrhage, the hematoma plays a major role in the stress effect of the surrounding brain tissue, and the study of the damage of the stress to the brain tissue plays a vital role in choosing the timing of surgery and prognosticating the prognosis. Researchers have made a balloon cerebral hemorrhage model in rats, and described in detail the changes in intracranial pressure and intracranial blood flow after intracranial balloon implantation in animals (rats), but failed to detect the brain tissue around the balloon Stress situation. [0003] In the case of an intracranial hematoma, the mechanical stress of the hematoma on the brain tissue is very complicated. Current research shows that the brain tissue is anisotropic, viscoelastic, and ...
