Description
Technical field:
This utility model relates to medical blood taking instrument field, is specifically related to the disposable self-destructing hemostix.
Background technology:
Hemostix is the necessary tool of collecting blood.
Existing hemostix complicated operation, penetrate that power instability, wound surface are big, pain is big, and have problem such as cross infection.
The utility model content:
The purpose of this utility model provides the disposable self-destructing hemostix, and it is easy to use, uses the back to destroy the mechanism reliability height, and it is low keenly feel, has avoided using the generation of situation of hurting sb.'s feelings of back hemostix, and there is not any cross infection problem in the while.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises safety box 1, spring 2, syringe needle 3, button 4 and lid 5; Be provided with groove 11 in the safety box 1, the centre of groove 11 is provided with axle 12, the top of axle 12 is provided with expansion inclined-plane 13, the bottom surface of safety box 1 is provided with draw-in groove 14, one end of spring 2 is provided with extension rod 23, extension rod 23 is connected with axle 12, the other end of spring 2 is provided with pressure apparatus 21, pressure apparatus 21 is connected with needle stand 22, the syringe needle 3 coaxial centers that are arranged on pressure apparatus 21 and needle stand 22, and the front end of button 4 inwalls is provided with grab 42, grab 42 is corresponding with draw-in groove 14, the both sides of button 4 inwalls are provided with elastic arm 41, and the front end face of button 4 is provided with pin hole 43, and lid 5 matches with safety box 1.
The surface of described safety box 1 is provided with shallow band, has anti-skidding effect.
Described elastic arm 41 offsets with needle stand 22, and needle stand 22 can be pushed in the safety box 1.
The described grab 42 to correspondence can avoid button 4 and safety box 1 to come off with draw-in groove 14.
Described syringe needle 3 is syringe needles that tool rail type straight line launches.
During this utility model operation, when light finger light press button 4, elastic arm 41 is expanded on the expansion inclined-plane 13 that is arranged in the safety box 1, thereby elastic arm 41 and needle stand 22 are broken away from, under the effect of inertia of the restoring force of spring 2 and spring 2 and needle stand connecting portion 21, syringe needle 3 ejects from the pin hole 43 of button Face, prick skin, this moment, button 4 bottoms withstood the extension rod 23 that is arranged on the spring 2, motion to button 4 produces cushioning effect, alleviated the pain of human body, under the restoring force of spring 2, syringe needle 3 is got back in the safety box 1, because button 4 base end wall spacing to extension rod, spring is limited to safety box 1 bottom, syringe needle 3 can not deviate from from pin hole 43 again, and then guaranteed to use the generation of situation of hurting sb.'s feelings of back hemostix.
This utility model is easy to use, uses the back to destroy the mechanism reliability height, and it is low keenly feel, has avoided using the generation of situation of hurting sb.'s feelings of back hemostix, and there is not any cross infection problem in the while.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture sketch map of the present utility model.
The specific embodiment:
See figures.1.and.2, this concrete enforcement by the following technical solutions: it comprises safety box 1, spring 2, syringe needle 3, button 4 and lid 5; Be provided with groove 11 in the safety box 1, the centre of groove 11 is provided with axle 12, the top of axle 12 is provided with expansion inclined-plane 13, the bottom surface of safety box 1 is provided with draw-in groove 14, one end of spring 2 is provided with extension rod 23, extension rod 23 is connected with axle 12, the other end of spring 2 is provided with pressure apparatus 21, pressure apparatus 21 is connected with needle stand 22, the syringe needle 3 coaxial centers that are arranged on pressure apparatus 21 and needle stand 22, and the front end of button 4 inwalls is provided with grab 42, grab 42 is corresponding with draw-in groove 14, the both sides of button 4 inwalls are provided with elastic arm 41, and the front end face of button 4 is provided with pin hole 43, and lid 5 matches with safety box 1.
The surface of described safety box 1 is provided with shallow band, has anti-skidding effect.
Described elastic arm 41 offsets with needle stand 22, and needle stand 22 can be pushed in the safety box 1.
The described grab 42 to correspondence can avoid button 4 and safety box 1 to come off with draw-in groove 14.
