Description
Technical field
The utility model relates to: in medical pathological tissue embedding process, a kind of pathological tissue constant temperature fold up professional electric heating forceps device in the embedding mould.
Background technology
In the organization embedding work of medical pathological examination, antimagnetic type tweezer with heating, pathological tissue is put rustless steel embedding mould bottom, is fixed on then in the paraffin that embedded box solidifies, again with paraffin fixedly the embedded box of pathological tissue from the embedding mould, separate.This method has obtained to use widely in clinical diagnosis.The common way of heating antimagnetic type tweezer: (1) adopts alcohol burner to heat common stainless steel tweezers head repeatedly.The problem that occurs is easily: when temperature is high, can cause the change of pathological cells tissue morphology, section diagnostic observation after being unfavorable for.And temperature can be stained with sticking pathological tissue composition when low on the tweezers, works as running hours, has increased the chance of cross-contamination between the specimen.Especially Pathologic specimen is endometrial tissue, face pathological tissue, liver when wearing cell outpatient service sampling such as tissue, has increased opportunities for contamination especially.(2) the heating work platform with embedding machine inserts the antimagnetic type tweezer head, and waiting temperature rises, and carries out embedding again.Though the second way has been eliminated the defective that temperature may be high, their common issue with is: the chance that cross-contamination is arranged between the specimen; The process of heating tweezers has increased the waiting time, has reduced work efficiency, has improved labor intensity.The time long time of tweezers heating in addition, the hand-held part since temperature transfer, hot problem is arranged.
The utility model content
For solving the deficiency in the above organization embedding, this utility model provides a kind of automatic constant-temperature electric heating tweezer.This automatic constant-temperature electric heating tweezer when pathological tissue is folded up the embedding mould, provides about 60 ℃ steady temperature at retained part.This homothermic instrument, touch the surface with the preheating of wax liquid pathological tissue the time, because both have identical temperature, can on tweezers, not be stained with sticking pathological tissue composition, this has not only eliminated temperature when high, can cause the problem of pathological cells change in organization, and eliminate front and back by the cross-contamination between the pathological tissue specimen of embedding.Owing to need not the waiting time, improved work efficiency, reduced labor intensity.The tweezers split, solved hot problem in addition.Be the each several part explanation below:
1, heater element adopts the PTC critesistor.It is a kind of semiconductor resistor with positive temperature sensitivity, has the characteristic that resistance value is little under the room temperature, resistivity raises and increases with temperature.When applying certain electrical power at PTC type ceramic components two ends, at first PTC type ceramic components will be generated heat rapidly, increases because resistance raises with temperature, and its after current reduces, and enters temperature constant state.
2, select the special tweezers of manufacturing of rustless steel for use, be divided into two parts by function.The front is the constant temperature tweezer body that is fixed with ptc heater spare, clamping pathological tissue, and the back is the tweezer handle that the operator hands.Because the tweezer body of clamping pathological tissue has the temperature about 60 ℃, after the electric heating tweezer energising heating, this temperature will be delivered to operator's portion of the handle of back along the tweezer body.This temperature makes the operator scald one's hand in long-time and can't use.So in the design electric heating tweezer constant temperature working portion and hand-held part from, middle usefulness has the heat insulation fixture of certain intensity, special processing to connect as one.The overwhelming majority of tweezers front end heat is just intercepted like this, makes long-time operation not have obstacle.The electric heating tweezer is connected on the power pack by insulated conductor, snap joint.
3, heating controller is the power pack of electric heating tweezer, is made up of power supply and display circuit.Adopt the alternating voltage input power supply of high-performance, wide region.This power supply is selected high-performance, jumbo Switching Power Supply for use, and its advantage is that output voltage stabilization, conversion efficiency height, unfailing performance are strong.The DC voltage of the output of power-supply controller of electric is designed to and can regulates and control.Its temperature range shows with three kinds of colors of a LED luminous tube.Power-supply controller of electric and display circuit are installed in the machine box, and DC voltage is exported through the snap joint seat.
4, according to the scale of each hospital and the difference of workload, the output of power-supply controller of electric has two-way and single channel output pattern.The power-supply controller of electric of two-way output can heat two electric heating tweezers simultaneously, and can control break-make respectively with switch.The power-supply controller of electric of single channel output can only heat an electric heating tweezer.
The beneficial effects of the utility model are:
1, can eliminate cross-contamination between the pathological tissue of embedding, for the character of correct diagnosis pathological tissue specimen provides guarantee.
2, controlling new electrically heating device and electronic technology easily, advantage combines.
3, the design that the working portion of electric heating tweezer and portion of the handle are separated has solved the problem of hand-held portion of hot hands.
4, in pathological tissue embedding working procedure, reduce operating procedure, improved work efficiency.
5. the scope of application is wide, can both adapted to the domestic and international embedding machine of any model.
6. heater element does not need special temperature controller, temperature sensor to carry out the Temperature Feedback control of generating heat, and its thermoregulation is the material behavior by self, thereby has the unexistent low cost of other heater.
7, heating is fast, heats up rapidly, and required electrical power is little behind the constant temperature, and there have thermostat temperature influenced by supply voltage to be minimum, the advantage that the life-span is long.
8, security performance is good.This heater body surface temperature is below 200 ℃, and body is all rubescent and protecting insulating layer is arranged in any case, thereby has eliminated potential safety hazards such as scald, fire.The dc low-voltage of power supply and the alternating current 220V of input are isolated, and do not have electrical shock hazard.
