Description

Auxiliary blood sampling device

Technical Field

The invention relates to the technical field of medical nursing products, in particular to an auxiliary blood sampling device.

Background

Blood sampling in the field of hematology nursing is an important item at present, and blood sampling refers to the process of collecting blood samples through veins and arteries by medical staff according to the needs of tests, so that blood sampling is performed on the elbow fossa or finger positions more commonly, and various diseases needed by a human body can be detected through blood sampling, so that blood sampling and blood sampling physical examinations are more and more standardized.

Medical personnel of hospital need tie up patient's big arm with pressing the arteries and veins area earlier when drawing blood for the patient, disinfect to drawing blood the region, the disinfection requires medical personnel to take disinfection cotton swab or disinfection cotton ball to dip in disinfectant or alcohol, then use blood sampling puncture point to rotate outward as the center and draw blood regional disinfection, abandon disinfection cotton swab in the regulation garbage bin after the disinfection, later puncture and draw blood, untie pressing the arteries and veins area after drawing blood begins, draw blood or draw blood and finish the back and abandon used syringe needle etc. device in placing sharp ware firmly in the container immediately, some patients move about with the fingers can influence the normal clear of work of drawing blood during the drawing blood, when treating that the person of drawing blood is more simultaneously, medical personnel's work load is great.

In addition, a patent with application number of CN202011236890.8 discloses a method for using an automatic skin disinfection pen machine before blood drawing in hematology department, a pushing block is pushed by a thumb to enable a disinfection cotton ball to fall down and be soaked when the disinfection cotton ball falls down, the soaked disinfection cotton ball falls between two L-shaped plates through a discharge port by self gravity, and then the soaked cotton ball is clamped and fixed by spring elasticity on two sides of the two L-shaped plates and then is wiped on the skin of a patient by a user.

For another example, patent with application number CN202111185542.7 discloses an automatic multifunctional venipuncture blood sampling device, wherein the patient places the arm on the arm binding seat, the vein vessel is highlighted when the vein component is pressed, the position of the device is adjusted, the position of the disinfection mechanism is adjusted by the adjusting component, the bottom plate of the disinfection mechanism is abutted against the skin of the patient, the highlighted vein vessel is limited by the strip-shaped opening, and the telescopic rod drives the cotton ball wiping head to move for wiping disinfection.

However, this has the following problems:

1. the device has the advantages that the device can clamp and disinfect the cotton balls by the characteristic that the sterilized cotton balls roll by gravity and easily slide, the clamping device usually selects the sterilized cotton balls dipped with sterilized water to clamp during disinfection, the sterilized cotton balls cannot be accurately clamped at proper positions, the sterilized cotton balls are fully contacted with skin, and the sterilized water in the sterilized cotton balls is squeezed and seeped out to cause the final disinfection effect to be unsatisfactory;

2. the automatic disinfection is carried out under the condition that an accurate disinfection position is not determined, and if the disinfection cotton ball only moves back and forth along the front and back direction of the arm, the disinfection position is staggered with the puncture position of the blood drawing puncture needle or the puncture position is positioned at the edge of a wiping disinfection area, so that the disinfection is insufficient.
