Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical experimental instruments, and in particular relates to a distal limb ischemia perfusion treatment device. Background Art
[0002] Remote limb ischemia treatment refers to multiple and short-term ischemia and reperfusion treatment of the body's limbs. The application of elastic bandages or cuffs to pressurize and then release to achieve periodic ischemia treatment, which then activates endogenous molecular protection signals and functions through multiple pathways such as humoral, neural, immune and autophagic transmission, thereby reducing damage to important organs. Remote limb ischemia treatment has the advantages of simple operation, non-invasiveness and low cost, and is expected to provide a new endogenous neuroprotective strategy for reducing brain damage.
[0003] At present, when conducting distal limb ischemia treatment experiments on traumatic spinal cord injury mouse models, elastic bandages are generally used to tie the mouse's proximal limbs as tightly as possible to completely block the limb blood flow and achieve reversible ischemia of the hind limbs. The limb ischemia is maintained for 10 minutes, and the bandage is relaxed for 10 minutes before reperfusion as an experimental cycle. This cycle is repeated every day for three days to observe the hind limb motor function, autonomous motor function, and pain-related behavior of mice with spinal cord contusion. However, this method is based on the experience of the experimenters. If the elastic bandage is tied too tight or too loose, it may affect the blocking and recovery of the mouse's limb blood flow. In addition, the elastic bandage may slip during the experiment, causing changes in tightness and affecting the accuracy of the experimental results. Utility Model Content
[0004] The utility model aims to solve the above-mentioned deficiencies of the prior art and provide a distal limb ischemic perfusion treatment device with quantitatively controllable tightness of an elastic bandage and no slippage during the experiment.
[0005] In order to achieve the above purpose, the technical solution adopted is:
[0006] A distal limb ischemic perfusion treatment device comprises an adjusting rod, a supporting frame, an elastic bandage and a locking unit, wherein the adjusting rod is composed of a knob and a connecting rod, and a bandage groove is arranged in the middle of the connecting rod; the supporting frame is a U-shaped structure, and sleeves matching the connecting rod are arranged at both ends, and the connecting rod can be installed in the sleeve and rotated, and a bandage channel is arranged in the middle; one end of the elastic bandage is connected to the outside of the supporting frame, and the other end is connected to the bandage groove through the bandage channel, and can be tightened or loosened by rotating the adjusting rod to achieve blocking or recovery of blood flow in mouse limbs; the locking unit is arranged inside the supporting frame, and can lock the position of the adjusting rod to prevent the tightness of the elastic bandage from changing.
[0007] As another preferred embodiment of the present invention, the knob is provided with a circumferential scale, and the sleeve near the knob is provided with scale markings, and quantitative control of the tightness of the elastic bandage is achieved by rotating the knob to a specific scale marking.
[0008] As another preferred solution of the utility model, the knob is provided with a knob texture to facilitate the position adjustment of the knob under the tension of the elastic bandage.
[0009] As another preferred solution of the utility model, the locking unit is composed of a slider, a spring and a paddle. The slider and the spring are arranged inside the support frame. The slider enters the sleeve under the action of the spring to apply damping to the connecting rod. The paddle is connected to the slider and extends to the outside of the support frame. The locking unit locks or unlocks the adjusting rod by changing the position of the paddle.
