Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example 1:
as shown in fig. 1 to 5 children's transfusion harbor not damaged needle puncture auxiliary device, including fixing base 1 and the pressing part 2 that is used for pushing down fixing base 1, fixing base 1 adopts transparent material, 1 marginal downward buckling or extension of fixing base forms and detains clamping ring 10, it is the arc to detain clamping ring 10 lower limb, and detain clamping ring 10 lower limb and adopt silica gel material, silica gel material has better compliance and skin affinity, can not cause the stimulation to skin, and children's skin is more delicate and sensitive, consequently, adopt silica gel can alleviate the oppression of clamping ring 10 to children's skin, avoid children's patient to produce great discomfort, painful sense or even pressure nature damage.
According to pressure piece 2 for encircleing the annular piece that fixing base 1 set up, the annular piece also adopts the silica gel material, not only has compliance and close skin nature, can prevent to cause pain or injury to children's patient's skin when pressing, has great frictional force moreover between silica gel and the skin, can prevent and patient skin between the slippage, be favorable to improving the not damaged needle puncture success rate.
