Description

Visual venipuncture brick and medical teaching aid platform applying same

Technical Field

The utility model relates to the technical field of medical teaching aids, in particular to a visual venipuncture brick and a medical teaching aid platform applying the same.

Background

Subcutaneous venipuncture is one of the most common medical procedures in hospitals and is an important means for clinical diagnosis and treatment. Venipuncture generally adopts two methods in clinic: one is visual method, namely, the blood vessel is positioned in a naked eye mode, and the position of the blood vessel can be seen by naked eyes as the position of the vein of part of the population is shallow and also is very prominent; the other is the touch method, which requires many years of clinical experience and distinguishes the position of the blood vessel by touching the skin to distinguish the tactile sensation of the blood vessel and the surrounding tissue. However, in practical applications, the venous access Difficulty (DVA) often occurs due to special situations of patients, for example, patients who are infants, children, obese patients, edema patients and the like cannot easily see veins, or patients who are chemotherapy patients, patients with poor elasticity of blood vessels, first aid, shock, patients with sharply reduced blood volume, patients with blood vessel collapse and the like for many times, and further, the venous puncture of medical staff is prone to be unsuccessful for many times.

At present, the vein puncture is mainly operated manually clinically, whether the vein puncture can be successfully performed by one needle completely depends on the experience of medical care personnel, namely whether the puncture is successful and whether the vein transfusion is missed or not is determined by selecting a blood vessel part, a puncture needle inserting angle, a puncture depth, a blood vessel blood returning needle inserting angle, a blood vessel indwelling position and the like, and for medical care students nursing in a health school and medical care personnel who do not have long clinical working time, the blood vessel is accurately selected, and the needle inserting angle and the depth are controlled with certain difficulty.

Chinese patent (patent No. 201910484639.4) discloses a method for manufacturing a human bionic blood vessel by using 3D printing in combination with a rollover process, the bionic blood vessel manufactured by the above method is closer to a human body structure, students are closer to clinic when puncture teaching aids for venipuncture injection of the bionic blood vessel are applied to the puncture, however, the teaching aids for venipuncture injection on the current market can only simulate a blood vessel shape, so that students or medical staff cannot simulate other parts for intravenous injection and the structure of the human blood vessel in each age level, and a large amount of practice is performed on the product, so that the actual operation capability of clinic cannot be improved.
