Abstract
The utility model discloses a rotating and drying device for chitosan nerve conduits. The device comprises a base, a frequency-conversion transmission device, a fixed plate and a movable plate, wherein twenty to fifty joints for fixing the nerve conduits are uniformly distributed on the fixed plate and connected with main transmission, and can rotate at a uniform speed; and twenty to fifty holes matched with the nerve conduits are distributed on the movable plate. The device can be axially rotated at an even speed and fixed on the nerve conduits on the joints, so that the quality non-uniformity of the nerve conduits, which is caused by weight, can be eliminated. By the adoption of the device, nerve conduits with uniform thickness can be obtained after drying.
Description
Technical field
The utility model relates to a kind of Rotary drying device that is used for dry chitosan nerve trachea, belongs to technical field of biological material.
Background technology
Along with the incidence of peripheral nerve injury is the trend that rises significantly, the treatment that new easy nerve repair material is used for peripheral nerve injury has great clinical demand.
After the peripheral nerve injury, the distal nerve certain condition can guide the growth of near section nerve down, and this condition is exactly to need a specific microenvironment.Under the guiding of this theory, nerve trachea has obtained development fast in recent years.Nerve trachea is normally with biological or the suitable tubular bracket of abiotic prefabricated one-tenth, and the neural broken ends of fractured bone of bridge joint is when providing the nerve regneration microenvironment, by the regeneration that neural chemotactic is induced, neurotrophic effect promotes nerve.The chitosan nerve trachea then has excellent biological compatibility and certain mechanical strength, be mainly used in the peripheral nerve injury reparation, the neural broken ends of fractured bone of bridge joint is when providing the nerve regneration microenvironment, by the regeneration that neural chemotactic is induced, neurotrophic effect promotes nerve.
The utility model content
The purpose of this utility model is at the air-dry moulding process in the manufacturing process of chitosan nerve trachea, because the influence of self gravitation, in dry run, can cause the problem of non-uniform of conduit, and a kind of Rotary drying device of design, can reach the influence of subduing gravity by rotation like this, drying obtains uniform nerve trachea.
In order to achieve the above object, the present invention takes following measures: design a kind of whirligig, can once place many conduits, rotate with same speed simultaneously, thereby reach the purpose of dry nerve trachea.It is characterized in that: this device comprises base (1), is arranged on Frequency Drive device (2) and a fixed head (3) and a removable plate (4) on the base.Even 20～50 the fixedly joints of nerve trachea that distribute on fixed head, each joint inside all links to each other with main transmission, speed uniform rotation that can be identical, corresponding 20～50 holes that are complementary with nerve trachea that distribute on movable plate.The spacing of movable plate and fixed head can be regulated between 1～40cm by slide block (5).

The specific embodiment
Further specify preferred forms of the present utility model and occupation mode thereof below in conjunction with accompanying drawing.
This device comprises base (1), is arranged on Frequency Drive device (2) and a fixed head (3) and a removable plate (4) on the base.Even 20～50 the fixedly joints of nerve trachea that distribute on fixed head, each joint inside all links to each other with main transmission, speed uniform rotation that can be identical, corresponding 20～50 holes that are complementary with nerve trachea that distribute on movable plate.The spacing of movable plate and fixed head can be regulated between 1～40cm by slide block (5).
During use, nerve trachea is fixed on the joint on the fixed head (3) together with mould, with runner (6) the removable plate that slides, the tip portion of nerve trachea is stretched in the corresponding hole just, regulate frequency converter to proper speed, nerve trachea is at the uniform velocity rotated, until the nerve trachea bone dry.This device can many nerve tracheas of primary drying, and the length range of nerve trachea is 3～40cm, and velocity of rotation can be regulated by frequency converter.
Claims (1)
1. Rotary drying device that is used for dry chitosan nerve trachea, it is characterized in that: this device comprises base, be arranged on the Frequency Drive device on the base, a fixed head and a removable plate, 20～50 fixedly joints of nerve trachea evenly distribute on fixed head, each joint inside all links to each other with main transmission, speed uniform rotation that can be identical, corresponding 20～50 holes that are complementary with nerve trachea that distribute on movable plate, the spacing of movable plate and fixed head can be regulated between 1～40cm.
