Description

Computer multichannel epidermic grafting machine

This utility model relates to medical apparatus and instruments, especially a kind of computer multichannel epidermic grafting machine.

At present, the epidermis separator of selling on the market is to adopt analog quantity two-way negative pressure temperature control table skin to separate head, its shortcoming is that temperature control precision is relatively poor, heat temperature raising has the temperature overshot phenomenon, and only can separate being subjected to dermatotome and skin donor site to carry out two place's epidermises simultaneously, each separation can only be finished place epidermic grafting treatment, generally finishes place epidermic grafting and moves the treatment operation and need time more than 40-60 minute, the overwhelming majority time is being waited the epidermis separation in the operation, so work efficiency is lower.

The purpose of this utility model just provides a kind of by computer control, the computer multichannel epidermic grafting machine that can carry out the many places epidermic grafting fast.

The purpose of this utility model is realized by following technical scheme:

Computer multichannel epidermic grafting machine is by main frame, negative pressure pump, epidermis separates head, the negative pressure pipe, formations such as cable, negative pressure pump and main frame are split type, negative pressure pump links to each other with main frame by the negative pressure pipe, epidermis separates in the head establishes heating load and temperature sensor, it is by the negative pressure pipe, cable links to each other with main frame, main frame is provided with function key, vacuum table, digital display tube, on and off switch, be provided with one-chip computer (computer) in the main frame, buffer, voltage comparator, add thermal actuator, temperature sensor links to each other with the input of buffer, the input of the output termination voltage comparator of buffer, the outfan of voltage comparator links to each other with the mould/number conversion input port of computer CPU, add thermal actuator by audion, resistance, solid-state relay is formed, and adds thermal actuator and is controlled by one-chip computer.Temperature sensor separates the Temperature numerical of head through buffer with epidermis, voltage comparator, the Temperature numerical of delivering to computer CPU and setting compares differentiation, if heating-up temperature does not also reach when temperature value is set, computer sends corresponding data pulse, driving adds thermal actuator, give the load heat temperature raising, make epidermis separate the interior temperature of head near design temperature, when approaching design temperature gradually when heating up, feedback data by temperature sensor is given computer, computer reduces the pulse number that driving adds thermal actuator gradually, until closing, makes epidermis separate the temperature constant that head keeps degree of precision.Computer can separate head to above-mentioned independent constant temperature epidermis more than four tunnel simultaneously to be controlled, and also can close two-way wherein, only carries out the control of two-way constant temperature negative pressure, and two digits displays temperature, four tunnel shared eight-digit number word displays temperatures are adopted in every road.

Computer multichannel epidermic grafting machine of the present utility model can be used for the affected skin transplanting that epidermises such as Bai Dianfeng, burned skin, perineum white macula lack melanocyte, can be accurately with epidermis and the spine cell of corium and separating of melanocyte layer no pain, and in being subjected to the dermatotome transplanting survival, be formed with the normal skin or the pigment island of pigment, need not the scutching medicine, have no side effect, need not be in hospital after the general operation.This machine adopts computer control, and constant precision height, good stability, reliable operation, automaticity are higher, easy and simple to handle, the epidermic grafting operation that the surgeon that has only higher medical skill of making over just can be finished, and now general dermatologist also can finish.
