TH11049B - Needle holder for blood collection - Google Patents

Abstract

The needle holder consists of a cylindrical cylinder, and the needle clamping mechanism is placed on the distal wall of the cylinder. The needle clamping mechanism consists of a first slider, a second slider, a retainer, and a frame. The first slider and retainer have a female half-section built onto them. The first slider can move to the second slider so that the mechanism is in the closed position, where the first slider is engaged with the frame, allowing the female half-sections to move together to form a complete female section. The second slider can move to the first slider so that the mechanism is in the open position, where the first slider is not engaged with the frame. The frame is attached to the cylindrical cylinder to hold the first, second, and retainer on its distal wall.

Claims (7)

1. The needle holder consists of a cylindrical cylinder with an open near end and a closed distal end, with an opening created in this distal wall. The needle gripping mechanism is positioned at the distal end of the cylinder. This mechanism consists of a first slider and a second slider. These sliders can move sequentially towards each other along the distal wall. When the first slider is moved towards the second slider, the mechanism is brought to the closed state, and when the second slider is moved towards the first slider, the mechanism is brought to the open state. 2. The clamping mechanism of the first pin consists of a first slider on which a female half is built, a clamp on which a female half is built, a second slider constructed so that the first slider does not slip out of the cylinder, and a frame for clamping the first and second sliders and such clamps on the end wall. When the first slider is moved, the second slider's female half slides together to align with the complete female half, and the first slider engages with such frame. When the second slider is moved towards the first slider, the first slider does not engage from such frame. 3. The two-sliding arm of the claim has a second slider that extends from the frame when the first slider is engaged with the frame, and the first slider extends from the frame when it is not engaged. The first slider can move to the second slider to engage the frame, and the second slider can move to the first slider to disengage it from the frame. 4. The holder of the two-sliding claim has a second sliding tab with an ear constructed onto it, and the holder has an opening through which such ear passes. 5. The holder of the three-sliding claim has a second slider with an ear constructed onto it, and the holder has a slot through which this ear passes. 6. The second slider of the two-slide claim will not protrude from the frame when the first slider is engaged with the frame, and the first slider will protrude from the frame when it is not engaged from there. The first slider can move to the second slider to engage the frame, and the second slider can move to the first slider to disengage from the frame. 7. The second slider of the six-position claim handle is colored.
