Vein searching instrument and using method thereof

Abstract

The invention discloses a vein searching instrument and a using method thereof. The vein searching instrument comprises a light source used for determining the position of a vein, and a shell covering the light source, wherein a triggering unit connected with the light source is arranged on the shell and used for identifying the using state of the vein searching instrument and controlling on-off of the light source. The vein searching instrument has the remarkable advantages that the triggering unit is arranged to identify the using state of the vein searching instrument and control on-off of the light source, so that the vein searching instrument only emits light when used; the light source used for irradiating skin, soft tissue and bones in a passing-through mode is arranged, so that vein vessels are easy to find, positioning is accurate, and vessel puncturing can be assisted; a fixing device is arranged, so that the vein searching instrument is convenient to wear and convenient and quick to use; cost is low, and popularization is easy; operation is easy, diversified switching modes of the light source are available, and requirements for touch control and light sensitization are met; a programmable controller is arranged so that using frequency and using time can be limited and the state of a power supply can be monitored.

Description

technical field [0001] The invention relates to a vein finder and a using method thereof, belonging to the technical field of medical instruments. Background technique [0002] Blood vessel puncture for superficial vein infusion mostly relies on medical staff to visually determine the position and direction of superficial vein blood vessels, especially children, weak or unconscious patients who cannot cooperate with medical staff, and in many cases, only by eye observation and fingertips It is still difficult to judge the specific location and direction of the superficial veins, even for experienced medical staff. [0003] Specifically, in the case of deeply buried blood vessels, thin blood vessels, poor blood vessel elasticity, and blood vessel damage caused by drug stimulation, etc., the venous blood vessel puncture is extremely difficult, and it is easy to cause puncture errors, and even cause medical accidents in severe cases, so it is urgent What is needed is a tool th...
