The technical scheme is as follows: the utility model provides a push type hemostix, which comprises a shell, a hair pushing device and a needle catapult, wherein two limit bosses and two positioning bosses are symmetrically arranged on the left side and the right side of the bottom of the inner side wall of the shell, and the two positioning bosses are respectively positioned on one side below the two limit bosses; the hair pushing device is positioned in the shell and is of a cylindrical structure, wherein two cambered elastic clamping claws are symmetrically arranged on the left side and the right side of the bottom of the outer side wall, and the top of the cylindrical structure is provided with a needle head outlet of the blood taking needle; the needle body catapult consists of a fixed seat and the blood taking needle, and the bottom end of the fixed seat is fixed at the bottom of the shell through a spring; the needle tail of the blood taking needle is fixed at the central axis of the fixing seat, and the needle head extends out of the top of the fixing seat and is opposite to the needle head outlet; before the hemostix is launched, the ejector is clamped on the two limiting bosses through the two cambered elastic clamping claws, the fixing seat is limited between the bottom end of the ejector and the spring, and the needle head of the blood taking needle is positioned in the ejector; after the hemostix is launched, the ejector is clamped on the two positioning bosses through the two cambered elastic clamping claws, the fixing seat is positioned in the ejector, and the needle head of the blood taking needle extends out of the needle head outlet; after the puncture is finished, the needle head of the blood taking needle is positioned in the hair pushing device.
Further, two sliding grooves with openings at the bottoms are symmetrically arranged on the front side and the rear side of the inner side wall of the hair pushing device, two limit sliding blocks matched with the two sliding grooves are symmetrically arranged on the front side and the rear side of the outer side wall of the fixing seat, and before the blood collector is emitted, the two limit sliding blocks respectively prop against bosses at the bottoms of the two sliding grooves; in the puncture process of the hemostix after the emission, the two limit sliding blocks are respectively positioned in the two sliding grooves.
Further, the push type hemostix also comprises a torsion bar, two limit convex shoulders are symmetrically arranged on two sides of the middle part of the torsion bar, when the hemostix is in a transportation state, the bottom end of the torsion bar is in breakpoint connection with the top end of the fixing seat, the limit convex shoulders are positioned inside the hair pusher and propped against the lower surface of the needle outlet, and when the hemostix is in a transmitting state, the torsion bar is separated from the hemostix. The limiting convex shoulder of the torsion bar is at a certain distance from the bottom end of the torsion bar, the two cambered elastic claws of the ejector can be clamped on the two limiting bosses on the inner side wall of the shell all the time, namely, the ejector cannot be pressed when the ejector is kept in a transportation state, so that the ejector can be ensured to be limited between the bottom opening ends of the two sliding grooves of the ejector and the spring all the time, the ejector is effectively prevented from being ejected in the transportation state, and cross infection caused by the ejection of the needle head of the ejector in the transportation state is effectively prevented.
Further, two guide grooves matched with the cambered surface elastic clamping claws are symmetrically and vertically arranged on the left side and the right side of the inner side wall of the shell, and the guide grooves are connected right above the limiting boss. When the hair pusher is installed in the shell, the two cambered surface elastic clamping claws can be smoothly clamped on the two limiting bosses through the guiding action of the two guide grooves respectively by the guide grooves, so that the hair pusher is convenient to install.

Because the ejection route of the fixing seat is likely to be not a straight line in the ejection process of the fixing seat, the ejection route of the fixing seat is likely to be a straight line, so that the ejection route of the blood taking needle is also a straight line, and the accuracy of the needle insertion position and the needle insertion effect are ensured.
Preferably, the planes of the two sliding grooves are perpendicular to the planes of the two cambered elastic claws. The design is also in order to ensure that the whole structure of the ejector is symmetrical, and ensure that the ejection route of the needle ejector is straight when the ejector is ejected as far as possible.
Working principle and beneficial effect: in the utility model, before the hemostix is launched, the needle ejector is limited between the bottom opening ends of the two sliding grooves of the ejector and the spring, at the moment, two limiting sliding blocks on the outer side wall of the fixing seat in the needle ejector are propped against the bottom opening ends of the two sliding grooves, and an angle is formed between the plane where the two limiting sliding blocks are positioned and the plane where the two sliding grooves are positioned, so that the needle ejector can be limited between the bottom opening ends of the two sliding grooves of the ejector and the spring, and at the moment, the needle head of the blood taking needle of the needle ejector is positioned in the ejector; when blood collection and puncture are needed, one end of the ejector with a needle outlet is aligned to the skin to be needled and is pressed towards the skin direction after contacting the skin, in the pressing process, the two cambered elastic claws of the ejector move to the two positioning bosses from the two limiting bosses, in the moving process, as the parts of the two cambered elastic claws of the ejector, which are contacted with the inner side wall of the shell, are provided with cambered structures, and the positioning bosses and the limiting bosses are in a dislocation relation, the ejector can rotate an angle in the moving process to move to the positioning bosses from the limiting bosses and be positioned by the positioning bosses, in the rotating process, the two sliding grooves on the ejector also rotate an angle along with the two limiting sliding blocks, the plane of the two limiting sliding blocks and the plane of the two sliding grooves are just rotated to the same plane, and the fixed seat is shot rapidly along the sliding grooves to the direction of the needle outlet of the ejector, under the action of the spring, when the two limiting sliding blocks move to the tops of the two sliding blocks are blocked by the convex shoulders of the sliding grooves, the two limiting sliding blocks stop moving, and the ejector can be shot to the outside of the needle outlet just outside the blood collection needle; after the puncture is finished, the fixing seat can quickly rebound to the spring direction for a certain distance under the action of the resilience force of the spring so as to bring the blood taking needle head outside the needle head outlet back into the hair pushing device during the puncture.
Therefore, before the hemostix is launched, the blood taking needle is always positioned in the ejector, so that cross infection caused by contact of medical staff or other people with the needle is effectively prevented; in the process of puncture after the hemostix is launched, when the needle head of the hemostix is ejected out of the needle head outlet of the pusher, the skin is quickly punctured, after the puncture is finished, the needle head of the hemostix can be quickly bounced back into the pusher by a spring, a patient cannot see the hemostix in the whole puncture process and after the puncture is finished, the fear of the patient (especially children) is effectively prevented, and the used hemostix cannot be punctured into hands of a collector because of the exposure of the hemostix, otherwise cross infection is avoided; when blood is sampled, the needle insertion can be realized by only sticking one end of the hair pusher with a needle outlet on the skin and then pressing the hair pusher, so that the operation is very convenient; in addition, the hemostix is simple in structure, safe and reliable.
