In particular, the base pad 1 of the present utility model has a rectangular shape and is made of a soft material, such as a soft leather material. In order to place the base cushion on the abdomen of the patient and prevent the base cushion from moving relatively, a binding belt 4 is arranged on the base cushion, for example, a binding belt is respectively arranged on the left side and the right side of the base cushion, the starting ends of the two binding belts can be respectively fixed on the base cushion in a sewing or gluing or magic tape connection mode, and the tail ends of the two binding belts can be connected together in a binding or other mode, so that the base cushion can adapt to patients with different abdomen sizes.

Above the base pad a skin-like layer 2 for simulating skin is arranged, which may be made of a flat piece of rubber material or of a material of the prior art which simulates skin. The skin-like layer can also be rectangular, the size of the skin-like layer is equal to or slightly smaller than that of the bottom pad, and the edge of the skin-like layer and the edge of the bottom pad are fixed together in a detachable (such as magic tape or snap connection) or non-detachable (such as sewing or glue paste and the like) mode. When a learner or a patient uses the subcutaneous skin model of the utility model to perform injection practice of the needleless injector, a medicine tube of the needleless injector is required to be closely attached to the skin-like layer.

In order to make the trainee or patient better feel the injection pressure of the cartridge of the needleless injector acting on the skin-like layer, a pressure detection layer 3 is arranged between the base pad and the skin-like layer, the pressure detection layer may also be rectangular, and the size is slightly smaller than the size of the skin-like layer, and it may adopt the following structure, including: the rectangular base layer can be made of the same material as the base pad, and is connected with the base pad in a detachable or non-detachable mode; the pressure sensors are fixedly arranged on the base layer, injection pressure of the needleless injector medicine tube acting on the skin-like layer when a trainee or a patient performs needleless subcutaneous injection training is detected through the pressure sensors, and the pressure sensors can be symmetrically arranged on the base layer at reasonable intervals when the pressure sensors are applied, and are fixed on the upper surface of the base layer through glue.
