The specific embodiment
For further understanding technology contents of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of automatic withdraw of the needle formula blood collecting pen comprises the cap for brush 5, penholder 1, trigger mechanism, and the cap for brush 5 is assemblied in penholder 1, is provided with the blood taking needle trigger mechanism in the penholder 1.Trigger mechanism has emission button 6, emission spring 7 and blood taking needle dress punch block 11.Dress punch block 11 has positioning edge 11.1 and emission shell fragment 11.2, the chute that has dress punch block 11 to slide in the penholder 1, and the corresponding assembling of positioning edge 11.1 with chute, emission shell fragment 11.2 and the emission button 6 corresponding assemblings that are installed on penholder, dress punch block 11 is equipped with emission spring 7.In the dress punch block 11 withdraw of the needle frame 10 is housed, withdraw of the needle frame 10 positions are provided with withdraw of the needle button 4, and withdraw of the needle button 4 is installed on penholder 1, can block withdraw of the needle frame 10 when withdraw of the needle button 4 is pressed.Dress punch block 11 even is equipped with withdraw of the needle pull bar 9, drives the dress punch block during 9 pullings of withdraw of the needle pull bar and moves.Withdraw of the needle pull bar return spring 8 is housed on the withdraw of the needle pull bar 9.Withdraw of the needle pull bar 9 mode that clamps connects adorns the withdraw of the needle 2, and the withdraw of the needle is equipped with end cap 3 on 2.
Automatic withdraw of the needle formula blood collecting pen course of action: after blood collecting pen is finished emission, press yellow withdraw of the needle button, the little hook at withdraw of the needle button rear portion can hook withdraw of the needle frame.When the post-tensioning acupuncture needle the time, can drive the dress punch block moves backward, but withdraw of the needle frame is owing to hooked by withdraw of the needle button, can not move backward, thereby cause relatively moving of dress punch block and withdraw of the needle frame, thereby the blood taking needle that withdraw of the needle frame will be adorned in the punch block ejects, and has so just avoided going blood taking needle is extracted with hands, realizes the automatic withdraw of the needle.
Using method of the present utility model:
Blood collecting pen blood sampling: take off the blood collecting pen cap for brush blood taking needle is put into blood collecting pen dress punch block, take off the blood taking needle protective cap, then the blood collecting pen cap for brush is covered, aim at the disinfectant blood sampling site and press the blue emission button and both can finish blood sampling.
Withdraw of the needle operation: blood collecting pen takes off the blood collecting pen cap for brush after finishing the blood sampling action, pins yellow withdraw of the needle button and pulls back withdraw of the needle handle simultaneously, and withdraw of the needle this moment button blocks withdraw of the needle frame, and withdraw of the needle frame withstands blood taking needle; By the withdraw of the needle pulling withdraw of the needle pull bar is driven the dress punch block and move, the blood taking needle in the dress punch block will be released by withdraw of the needle frame, realizes the purpose of the automatic withdraw of the needle.Blood taking needle ejects from blood collecting pen automatically, and At time of eject notices that blood taking needle should be placed on special-purpose the recovery in the utensil.
The utlity model has the advantages such as described safety and sanitation, simple in structure, easy to operate, quickness and high efficiency, the scope of application are wide, can be widely used in the health care health industry.
