The during operation, to keep somewhere the needle and insert patient's back of the hand vein, at this moment with pasting board 204 alignment syringe needle, the transparent application of applying ointment or plaster that sets up bottom pasting the device on the back of the hand through pressing down casing 1 after make filler strip 207 laminate completely with the back of the hand, pasting board 204 received to drive after the extrusion and stabilized lug 205 at the inside up-motion of stabilizing groove 201 this moment, stabilized lug 205 through spacing slider 206 at the inside stable up-motion of spacing groove 202, prevent that pasting board 204 from appearing rocking and unable effectual problem of installing the work of going on when pasting, the operating efficiency has been improved, and then be convenient for the installation work of device, improve the practicality of device, fix the needle of keeping somewhere through transparent application, at this moment with the syringe needle pipe alignment first constant head tank 3, coil into the shape of first constant head tank 3 with the syringe, the bottom of the junction of needle pipe and lift groove 902 butt through lifting groove 902, at this moment with last casing 5 closed with casing 1 again, make magnetic attraction magnetic stripe 7 and magnetic groove 4 each other, it makes second needle pipe 6 align to carry out the fixed stability of needle pipe and carry out the fixed constant head tank and carry out the circumstances that the crooked constant head tank through lifting to the fixed of second needle pipe after the fixed the constant head tank 3 appears.
Meanwhile, when the upper housing 5 and the lower housing 1 are closed, at this time, after the upper housing 5 drives the lifting contact rod 906 to abut against the needle tube, the lifting contact rod 906 can move upwards in the lifting groove 904 and stretch the second spring 905 under the support of the needle tube, the lifting contact rod 906 enables the sliding rod 907 to drive the first clamping block 909 and the second clamping block 912 to move towards two sides on the first stabilizing rod 908 through the guide chute 913 in the upward movement process, at this time, the pushing rod cannot contact with the limiting plate 920, the limiting plate 920 moves inwards on the third stabilizing rod 918 under the stretching action of the fourth spring 919, at this time, the blocking plug 917 is compressed after being pulled outwards manually, the blocking plug 917 is limited after the limiting plate moves inwards 920, at this time, the first strap 801 and the second strap 804 are wound under the arm, at this time, the second strap 804 penetrates through the notch of the penetrating slot, the fixing head 805 is clamped in the fixing groove 802, further, the device is fixed on the arm, the needle can be further fixed, the needle can be prevented from moving when the needle tube moves, the needle can be prevented from being pulled, the problem of needle, and the needle conveying stability is reduced, and the problem of needle damage to the vein can be caused.
When strong or large-amplitude movement occurs, disconnection occurs at the joint of the needle tube at this time, and further the lifting contact rod 906 cannot contact with the needle tube, the lifting contact rod 906 moves downwards in the lifting groove 904 under the action of the contraction of the second spring 905, the lifting contact rod 906 enables the sliding rod 907 to drive the first clamping block 909 and the second clamping block 912 to move to the inside of the blocking groove 910 towards the middle part on the first stabilizing rod 908 through the guide chute 913, the second clamping block 912 moves towards the inner side and drives the blocking plug 917 to move to the middle position, at this time, the push rod 911 contacts with the limiting plate 920 and then is squeezed, so that the limiting plate 920 moves towards the outer side on the third stabilizing rod 918 and compresses the fourth spring 919, at this time, the limiting plate 920 cannot limit the blocking plug 917, the blocking plug 917 moves towards the inner side in the second spring 915 under the action of the contraction of the third spring, and further blocks the disconnected joint, so as to prevent blood in veins from flowing out from the needle tube, and prevent air from entering the inside of the pipeline, thereby realizing the protection of the disconnected needle tube 916 and improving the safety of the use of the needle tube.
In particular, the components in the present application are all common standard components or components known to those skilled in the art, which effectively solve the problem that blood may flow after the indwelling needle is disconnected from the needle tube, which cannot be effectively protected.
