Description

Automatic time control and pressure regulation scald apparatus

Technical field:

This utility model relates to a kind of scald apparatus for preparing animal scald wound model, is specially automatic time control and pressure regulation scald apparatus.

Background technology:

The animal scald wound model of setting up standard is to carry out basis and the prerequisite that burn wound repairs research and estimates curative effect of medication.Standardized animal scald wound model is meant the size of making scald wound, shape, the degree of depth has very high degree of accuracy, concordance and repeatability, want the animal scald wound model of production standardization just to require the burning (scalding) of analogue formation to hinder instrument and must have constant compression force and temperature, the accurate scald time, and, animal do not influence the making of model when scalding because of moving, instrument also should be suitable for the making of each position scald wound model of middle-size and small-size animal (as the rabbit ear, the side of Mus trunk etc.), have only that the instrument that reaches these conditions fully just may production standard, repeatably burn (scalding) and hinder the wound surface model.

The existing equipment of making the scald wound model mainly contains two classes:

One class is to be thermal source, to perm as the scald equipment (being called for short burn equipment) of heating power carrier with metal with hydrothermal solution or electric power, and the factor that influences the scald wound degree of depth is mainly perms temperature and grant the pressure of being scalded on the object.But this kind equipment has the following disadvantages: after the scald time arrives, perm by manually removing, make the scald time of making a plurality of scald wound models be difficult to unanimity; In addition, perm and have cooling in various degree along with scalding the time lengthening metal, also may occur rocking when scalding and perm by the metal of artificial assurance, rock more obvious when particularly animal moves, therefore can cause perm pressure and occur changing with skin contact of metal, these unstable factors cause scald wound out-of-shape, the degree of depth inhomogeneous.

Another kind of be thermal source with steam, the equipment (being called for short cold perm equipment) of directly scalding with steam, the pressure of steam is corresponding with certain temperature, the big more temperature of pressure is high more, but steam pressure is not that " pressure " itself but temperature by steam produces to the influence of the scald wound degree of depth, so it is relevant influence time of main temperature, the scald with steam of the factor of the scald wound degree of depth during cold perm equipment making model.The scald time of existing cold perm equipment is controlled by cutting off steam manually, and scald also is difficult on the time be consistent when making a plurality of scald wound model; The steam pressure of existing cold perm equipment can not be regulated as required and can only work down at a kind of big pressure (900mmHg) in addition, and the globule that steam produces is not collected and the drain measure yet, both has been unfavorable for controlling, and also easily injures animal and operator; Moreover animal need be shelved on and scald on the support during scald, and difficult will scalding in advance a little aimed at the scald hole and fixed, and the slight jitter of animal also can make animal be shifted during scald, causes scald wound out-of-shape, the degree of depth inhomogeneous.

Owing to be subjected to the influence of above-mentioned factor, make existing heat (vapour) ironing equipment can not reach the needed full terms of production standard animal scald wound model fully, influence the accuracy of animal scald wound model, and then influence result of study.

The utility model content:

The technical problems to be solved in the utility model provides a kind of automatic time control and pressure regulation scald apparatus that can accurately regulate and control scald time, steam pressure and temperature.

The technical solution of the utility model is as follows:

Automatic time control and pressure regulation scald apparatus comprises steam generator and steam jet, and pressure-regulating valve, thermometer and Pressure gauge are installed on the steam generator; Steam generator is communicated with steam pipeline with steam jet, on the steam pipeline path, be provided with electromagnetic valve and vapour, water discharging valve, vapour, water discharging valve are between electromagnetic valve and steam jet, and electromagnetic valve is connected with the time controller circuit, and time controller is switch activated with time controller.

Described steam jet is made with foam or other heat-barrier material, has a logical steam vent that runs through this foam or heat-barrier material on the foam or on the heat-barrier material, and its bore is less than the interior bore of steam pipeline; Periphery at logical steam vent has annular groove one, and its degree of depth is less than the degree of depth of logical steam vent, and the opening of this annular groove is connected with steam pipeline; Steam output end at steam jet also is provided with the steam discharge side opening that at least one communicates with logical steam vent.Do not bring condensed water when such design makes steam by steam jet into, the condensed water that produces then can be discharged by the vapour on the vapor pipe, water discharging valve.

For the condensed water that prevents the steam pipeline tube wall enters logical steam vent, need to exist certain spacing (the two does not communicate) between the medial wall of logical steam vent and the medial wall of annular groove, be generally 0.3～0.5cm.The number of described steam discharge side opening can be determined as required, is generally 2, lays respectively at the both sides of logical steam vent.

For the shape and the degree of depth of controlling scald wound when the production standard scald wound model better, the shake of avoiding animal in the scald process exert an influence to the scald wound of making, automatic time control and pressure regulation scald apparatus described in the utility model comprises that also one scalds mould.This scald mould comprises plate washer, handle and hollow pipe, and the interior bore of hollow pipe is greater than the bore of logical steam vent on the steam jet; Hollow pipe is fixed in an end of handle, and vertical with handle, and barrier casing is loaded on the outer surface of hollow pipe.This scald mould can make things convenient for, be fixed on effectively animal and intend the scald place, even animal has certain shake in the scald process, scalds mould and displacement also can not occur, has guaranteed accuracy and the concordance of scald wound on shape, size and the degree of depth.

Described steam generator can be any equipment that can produce the high temperature high voltage resistant of steam, and what this utility model adopted is common pressure cooker.

Described pressure-regulating valve is manual adjustable steam pressure valve.

Described thermometer is for measuring the common thermometer of vapor (steam) temperature, and what this utility model was selected for use is digital display thermometer.

Automatic time control and pressure regulation scald apparatus described in the utility model can be controlled the scald time accurately with time controller and electromagnetic valve auxiliary work; Owing to pressure-regulating valve and Pressure gauge are installed on steam generator, can regulate in real time to satisfy the different experiments needs steam pressure as required; Special steam jet cooperates vapour, water discharging valve to solve the scald that the steam globule in the steam scald process may cause animal and operator well; Scald mould and can be fixed on animal plan scald place effectively,, scald mould and also can not move, can still keep the even and regular shape of the scald wound degree of depth even animal has certain shake in the scald process.Compared with prior art, automatic time control and pressure regulation scald apparatus scald time described in the utility model and steam pressure and temperature precise control, handling good and easy and simple to handle, stable performance, safe, and the displacement of the scald mould that the animal shake causes can prevent to scald well the time, make the scald wound border of making regular, shape is accurate with consistent, the degree of depth of size, good reproducibility, is the equipment of production standard animal scald wound model ideal.
