Problems solved by technology

Although the current mechanical pressure sore method does not require skin incision, it also has limitations. Because the animal’s body cavity cannot withstand mechanical pressure to build a model, it can only continue to apply pressure on the skin from the greater trochanter to the anterior tibia of the lower limb of the animal.

Embodiment Construction

[0017] Self-made pressure ulcer modeling experimental device, 60 cm wide, 55 cm high, 30 cm deep modeling room, 50 cm deep console (including 20 cm table). The operation steps of the application example are introduced as follows: (1) 50 rats weighing 220g-290g were gently removed from the modeling site with 8% sodium sulfide solution one day before modeling. After intraperitoneally injecting anesthesia with 10% chloral hydrate (300ml / kg), put the rat prone on the concave constant temperature platform, and lock the lower waist and upper chest of the rat with the Velcro fixing belts on both sides of the constant temperature platform, and the prone rat experiment The limbs are just placed on both sides of the bed platform and locked with Velcro fixing belts, just like rats standing normally. Then push the rat and the concave constant temperature fixed table together into the modeling room to connect to the ground rail and lock them, then set the automatic monitoring of temperatur...

Abstract

The invention aims at providing a pressure sore molding experiment device, and discloses a pressure-adjustable A-shaped clip pressure sore molding animal experiment device. The pressure sore molding experiment device has the advantages that the preparation is convenient and simple, the pressure is accurate, the repeatability is good, and the large-scale rat or rabbit pressure sore molding experiment can be performed. A pressure-adjustable A-shaped clip pressure sore molding animal experiment device can be pinch a part from the inner side of an animal thigh or skin to apply pressure without performing animal skin injury operation; the flow rate of local blood can be controlled of a molding clamp opening of the pressure-adjustable A-shaped clip, and a local tissue is pressed for a time to form hypoxic-ischemic necrosis, thereby forming a pressure sore model.

Description

technical field [0001] The invention relates to an animal experimental device for pressure-adjustable A-type pressure ulcer modeling, which is not an invasive mechanical compression modeling experiment. This kind of experiment needs to anesthetize the animal first, and then use the mechanical compression molding device to treat the local skin tissue of the experimental animal. Appropriate pressure is applied, local blood flow is controlled, and local tissue ischemia-hypoxic necrosis is formed to form a pressure sore model, in order to provide researchers with a suitable chronic refractory pressure sore model for research. Background technique [0002] Clinical pressure ulcers are more common in patients who are comatose, paralyzed, bedridden, debilitated, and fixed or bedridden for a long time after fracture. The occurrence of pressure ulcers not only brings unbearable pain to patients, reduces their quality of life, increases the economic burden of patients and their famili...
