The skin scalding device for the small animals has the advantages of being reasonable and ingenious in design, convenient to use and operate, simple in structure and low in manufacturing cost, and can be widely applied to establishment of models of the small animals with different scald areas and different scalding degrees.

Description

Meiofauna skin scald device

Technical field

This utility model relates to the middle-size and small-size mammal of basic medical research and tests relevant experiment apparatus, relates in particular to a kind of scald device of minitype animal experiment skin.

Background technology

It is the important means of research skin self-regeneration and other repair medicine curative effects to the skin burn of laboratory animal.The at present making of scalding model is mainly hot water is directly immersed in the scald position of laboratory animal or to scald with the metal after heating.But scalding area is uncontrollable owing to directly immersing in hot water, and direct heating ironware gives pressure (it is larger that same temperature gives pressure, the scalds more serious) difference of scalded skin while scalding.Therefore, traditional skin scald device can not well be controlled scalding area and scald degree at present, and the two very likely causes the error between laboratory animal, affects experiment effect and conventional efficient.

The content of utility model

For the problems referred to above; this utility model provides a kind of device of scalding; use this scald device can effectively control scalding area and scald degree; ensure to scald the homogeneity at position; can improve under the prerequisite of conventional efficient; the individual variation of the laboratory animal that minimizing scald process causes, also can exempt from scald in other position of Protection animal simultaneously, ensures to obtain reliable and stable experimental result.

This utility model is achieved through the following technical solutions:

A kind of meiofauna is scalded device, comprises water-bath, thermometer and plastic foamboard, and plastic foamboard is arranged in water-bath, and above its liquid level, plastic foamboard is provided with hole.Thermometer is used for measuring water temperature.

Described water-bath, for opening is large, guarantee to put into the model of animal to be tested;

Described plastic foamboard, its large I is determined according to place laboratory water-bath, guarantees to be stuck in water-bath.

Place for convenience plastic foamboard, can be provided with plastic foamboard stopping means by water-bath inwall; For example boss or draw-in groove.

Described water-bath has the following advantages as the container of containing hot water: water-bath can be good at keeping the constant of water temperature, is easy to control laboratory animal heat shock treatment conditions, and the error between laboratory animal is reduced; Water in water-bath can reuse and avoid waste simultaneously.

Described plastic foamboard, is the plastic foamboard of certain thickness (2-3cm), and its size is stuck in (as shown in Figure 1) in water-bath just;

Described scald hole, for a hole of digging in the middle of plastic foamboard plate, its pore size can be determined according to the scalding area of requirement of experiment, and laboratory animal can contact certain hour with hot water in water-bath by closely pressing close to this aperture after scalding position depilation, can obtain the circular wound surface of particular area.

Described water-bath, in the middle of its institute's hot water of containing and plastic foamboard, aperture upper surface maintains an equal level.

Foam plastics has good effect of heat insulation and can effectively damage location be controlled in circular hole, the detection of HE section pathomorphology confirms that wound surface and the boundary of surrounding normal skin histology that this installs the scald forming are obvious, proves that this device can be good at controlling the size of scald wound.

The heat conduction of water is more even with respect to metal, therefore applies hot water and scald the homogeneity of the wound surface degree of injury that can effectively control scald.

100 described degree celsius temperature meters, it is inserted in plastic foamboard, variation that can Real-Time Monitoring water temperature, the surrounding that is inserted in " scald hole " can monitor water temperature more accurately.

Application plastic foamboard separates hot water and experimental implementation person, prevents experimental implementation person's scald.

Keep whole experimentation hot water liquid level constant, just can effectively control hot water to zoodermic pressure, different experiments animal individual degree of injury is effectively controlled.

This utility model can also do and improve:

The diameter in the scald hole in plastic foamboard can change the requirement of scalding area according to experiment, also can on a cystosepiment, make the aperture of different pore size, to use the requirement of different experiments animal or experimental design.

If laboratory animal immunity is poor, need under relatively aseptic condition, damage, can test and the previous day plastic foamboard and temperature be taken into account to water-bath inner surface and spend the night with alcohol-pickled, and this device is moved in superclean bench and damaged.

Compared with prior art, effective effect that this utility model has has:

1) meiofauna of the present utility model is scalded device, has effectively controlled the size and shape of scald wound by the heat insulation effect of plastic foamboard; Keep the constant of water temperature by water-bath; Thermometer Real-Time Monitoring is scalded the hole variation of water temperature around; In a word, this device can obtain stable scalding model, and then obtains reliable, stable experimental result.

2) meiofauna of the present utility model is scalded device, reasonable in design ingenious, uses easy to operate.

3) meiofauna of the present utility model is scalded device, can be according to self laboratory apparatus article, and simple in structure, cost of manufacture is low, can be widely used in the scald research of all kinds of small-sized mammalians.

Brief description of the drawings

Fig. 1 is this utility model structural representation.

Wherein: 1: water-bath; 2: thermometer; 3: plastic foamboard; 4: scald hole.

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is described further, but the present invention is not caused to any restriction.

Embodiment: make the dark II degree of the skin scalding model that diameter is 1.5cm at SD rat back.

First on plastic foamboard 3, make aperture and be the aperture of 1.5cm as scalding hole 4, this plastic foamboard is stuck in water-bath 1, and thermometer 2 is inserted on this plastic foamboard, in water-bath, add suitable quantity of water (maintaining an equal level with plastic foamboard upper surface), water-bath temperature is adjusted to 80 DEG C, and observes thermometer to detect water temperature situation in water-bath.

By the SD rat anesthesia of 200g-350g and by skin of back depilation, both hands are taken away after picking up and exposed skin of back closely being pressed close to scald hole 410s clock after rat immediately, and can obtain round diameter is the dark II degree scald wound of 1.5cm.

Can scald by change the diameter change scalding area in hole (4); In change water-bath, the temperature of water and the time of damage are controlled the degree of depth of damage.
