Abstract

The high-simulation skin body is formed by pouring a skin layer, a subcutaneous tissue layer and a dermis layer from inside to outside in a layering manner, and the skin layer and the dermis layer are softer than the subcutaneous tissue layer. The high-simulation skin is worn on the arms of the student to create a more practical exercise environment, the overall structure of the high-simulation skin is designed according to the physiological structure of the arms of the human body, and the high-simulation skin is more attached to the skin after being worn; the high-simulation skin is convenient to wear, does not need to preset a skin dome, can be used for performing intradermal injection exercises for multiple times at the same part and forms the skin dome.

Description

Wrist strap type intradermal injection high-simulation skin

Technical Field

The utility model relates to a medical teaching aid field, concretely relates to high emulation skin of wrist strap formula intradermal injection.

Background

Intradermal injection is a pioneer procedure used to inject drugs below the epidermis, generally above the dermis, but below the subcutaneous tissue of the skin, and is mainly used for skin allergy testing, vaccination, and local anesthesia. The intradermal injection is an operation skill which needs to be mastered by medical staff and students in school doctors, and most of the medical staff and students in school doctors still adopt real-person actual operation when practicing the intradermal injection at present, namely, the medical staff and the students in school doctors practice on hands of opposite parties, so that great pain is caused to students who learn the operation skill, the mental stress of operators is caused, and the practice effect is greatly reduced.

SUMMERY OF THE UTILITY MODEL

Carry out intradermal injection exercise for the student in order to solve current adoption real person's arm and bring painful problem to and adopt and carry out subcutaneous injection on the single-layer silica gel and have fragile problem, the utility model designs a high emulation skin of wrist strap intradermal injection, this high emulation skin is dressed on student's arm, builds more actual exercise environment, and the overall structure of this high emulation skin designs according to the physiology structure of human arm, laminates skin more after dressing.

The utility model discloses a reach above-mentioned technological effect, adopt following technical scheme to realize:

the wrist strap type intradermal injection high-simulation skin comprises a high-simulation skin body, wherein the high-simulation skin body is conical, the high-simulation skin body sequentially consists of a surface layer, a subcutaneous tissue layer and a dermis layer from outside to inside, the high-simulation skin body is formed by pouring the high-simulation skin body in layers from inside to outside, the surface layer, the subcutaneous tissue layer and the dermis layer are all made of synthetic silicone rubber materials, and the surface layer and the dermis layer are softer than the subcutaneous tissue layer; the length of the high simulation skin body is 13cm, the thickness of the epidermis layer is 1-2mm, the thickness of the hypodermis layer is 2mm, and the thickness of the dermis layer is 1 mm.

The utility model has the advantages that: the high-simulation skin is worn on the arms of the student to create a more practical exercise environment, the overall structure of the high-simulation skin is designed according to the physiological structure of the arms of the human body, and the high-simulation skin is more attached to the skin after being worn; the high-simulation skin is convenient to wear, does not need to preset a skin dome, can be used for performing intradermal injection exercises for multiple times at the same part and forms the skin dome.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

FIG. 1 is a schematic diagram of the overall structure of a wrist strap type intradermal injection highly simulated skin;

fig. 2 is a schematic sectional structure view of a wrist strap type intradermal injection high simulation skin.

In the drawings, the components represented by the respective reference numerals are listed below:

1-epidermal layer, 2-subcutaneous tissue layer, 3-dermal layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-2, the wrist strap type intradermal injection high simulation skin comprises a high simulation skin body, wherein the high simulation skin body is conical, the high simulation skin body is sequentially composed of an epidermal layer 1, a subcutaneous tissue layer 2 and a dermal layer 3 from outside to inside, the high simulation skin body is formed by pouring the high simulation skin body in layers from inside to outside, the epidermal layer 1, the subcutaneous tissue layer 2 and the dermal layer 3 are all made of synthetic silicone rubber, and the epidermal layer 1 and the dermal layer 3 are softer than the subcutaneous tissue layer 2; the length of the high simulation skin body is 13cm, the thickness of the epidermal layer 1 is 1-2mm, the thickness of the subcutaneous tissue layer 2 is 2mm, and the thickness of the dermal layer 3 is 1 mm.

One specific application of the device is as follows: the two persons practice in a cooperative mode, one person wears the wristlet type intradermal injection simulation skin on the forearm to serve as a skin test person, the other person uses a cotton swab dipped with 75% alcohol to sterilize according to the position of the palm side 1/3 of the forearm wearing the wristlet type intradermal injection high simulation skin, liquid medicine is taken out, a needle head is adjusted, 1 drop of air is exhausted, the high simulation skin on the palm side of the forearm is tightened by the left hand, the injector is held by the right hand, the inclined surface of the needle head is upwards and penetrates into the epidermal layer 1 at an angle of 5 degrees with the epidermal layer 1, and the epidermal layer 1 and the subcutaneous tissue layer 2 are different in softness, so that whether the puncture needle head punctures to the interface of the epidermal layer 1 and the subcutaneous tissue layer 2 or not can be judged according to the blocking feeling of puncture. The left thumb of an operator fixes the pintle, 0.1ml of liquid medicine is injected into the right hand, and as the softness of the epidermal layer 1 is smaller than that of the subcutaneous tissue layer 2, the liquid medicine injected between the epidermal layer 1 and the dermal layer 2 jacks up the local part of the epidermal layer 1 to form a skin dome; with slow absorption in the dermal layer 2, the skin dome slowly disappears, completely simulating the course of an intradermal injection.

In the description herein, references to the description of "one embodiment," "an example," "a specific example," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
