Description
Technical field
The present invention is suppression pain peripheral blood sampling device, belongs to blood sampling apparatus field.
Background technique
The blood routine detection of general common diabetes glucose blood sugar monitoring and infant are all using tip blood sampling point mode.
Tip blood sampling common at present is completed by needle thorn, there is the needle Zha Shicai of bullet the pin type blood sampling and pediatric hospital of diabetes patient
Blood.
Specific blood collection procedure is then to pierce through skin in the form of disposable needle bundle using the alcohol swab cleaning third finger
Skin obtains finger tip blood.When paediatrics takes a blood sample to infant, blood is taken to expand wound with greater need for trigone needle-penetration skin.
Such Blood collection makes people nervous and causes severe pain, especially for needing to monitor blood glucose for a long time
Patient and infant will cause strong panic sense, while being also strong pain.
At present in terms of the pain for mitigating finger tip blood sampling, in terms of also resting on the wound face for reducing blood sampling, by tight
Lattice control the depth that blood taking needle penetrates to mitigate pain.But such method is only applicable to need frequently using finger tip blood sampling
Diabetic；For the infant of paediatrics, each blood routine examination is still and the trigone puncture thorn of very pain is needed to adopt
Blood.
And root is it was found that the main reason for causing pain in collecting is lacerated wound, finger tip lacerated wound is experienced by nerve endings to be passed
It leads, then transmits pain signal to people.On this Research foundation, sense of the nerve ending to finger tip wound is reduced or avoided
It answers, pain in collecting is reduced.
And pass through the study found that firmly compressing around the region that will take a blood sample can be to the biography of nerve ending in blood collection procedure
It leads and carries out interference obstruction, to realize that the pain of blood sampling reduces effect.And the principle of negative pressure is used, it is able to achieve to blood sampling region week
The effective compressing enclosed to the obstructive also very good of nerve, and not will cause sequelae, pain in collecting can be effectively reduced.
On the other hand, traditional analgesia method is ice compress, around the cooling blood sampling region of refrigeration means, can be reached
Analgesia suppression pain effect well.

In one embodiment, the bullet needle cavity lower end surface is pasted with cushion, and the setting of cushion top is playing inside needle mouth.
Beneficial effects of the present invention: suppression pain peripheral blood sampling device of the invention, the present invention is by adding upper needle compression bar, playing needle
Structure, refrigerating chamber, plays needle cavity, plays needle mouth, valve, connecting pipe, negative pressure cavity and negative pressure component needle stand, design structure letter
Single, the implementation method of air negative pressure principle is very simple, and reliability greatly improves, and front end refrigeration reduces logical sense, negative pressure when acupuncture treatment
Inhibit pain, can effectively subtract pain suppression pain, play needle construction and use rail mounted, have quick back stitching function after playing needle pop-up, can effectively subtract
The wound of few aculeus blood-taking reduces pain, solves at present in terms of the pain for mitigating finger tip blood sampling, also rests on reduction
In terms of the wound face of blood sampling, pain is mitigated by depth that strict control blood taking needle penetrates.But such method is only applicable in
In the diabetic for needing frequently to take a blood sample using finger tip；For the infant of paediatrics, each blood routine examination is still
The problem of needing the trigone of very pain to pierce puncture blood collecting.
Because adding cushion, this design reduces the pain degree of pressing, and the present invention is easy to use, can fast and effeciently reduce
The feeling of pain of aculeus blood-taking can be used for pediatric hospital blood sampling, can be used for family diabetes patient blood sampling.
