Description
Technical Field
The invention relates to a needle head used by an individual to collect blood, in particular to a striker self-rebound mechanism arranged in the needle head.
Background
Currently, most personal blood monitoring test instruments (such as blood glucose meters) utilize a lancing needle (also known as a needle insertion) to perform blood collection by striking the needle with a striker assembly that includes a spring, a striker shaft and a needle hub to cause the needle of the needle to penetrate the skin of the patient.
When a user performs a blood sampling operation, the following operation steps are performed:
1) Firstly unscrewing a gland of the blood sampling pen (the gland diagram is omitted), assembling the puncture needle on the needle head socket, and screwing the gland;
2) Starting a spring or a firing pin shaft to enable the puncture needle to impact forwards and puncture the skin of a patient;
3) After blood collection, unscrewing the gland, taking out the waste needle, discarding the waste needle, and screwing the gland.
The above-mentioned conventional blood sampling technique has the following main disadvantages:
1) In order to facilitate operation, the structure of the needle socket is often designed to be simpler (for example, only one sleeve capable of being inserted for inserting a needle is arranged, a larger assembly gap exists between the inner diameter of the sleeve and the needle, namely, loose fit is adopted, manual installation for inserting the needle is facilitated, the needle can not be synchronously withdrawn with the needle in the high-speed rebound process of the striker shaft after impact is easy to cause, the needle can be easily separated from the needle socket, the needle withdrawal is delayed, the retention time of the needle point of the needle in a wound of a patient is overlong, and the needle point of the needle can not be withdrawn when serious is likely to be continued to stay in the wound of the patient.
In addition, in the operation of inserting and taking the blood, the needle point of the puncture needle is always in a naked state, and accidents of scratching a patient can occur at any time, especially when the blood is taken for children.
2) Before all blood collection needles are placed in the spring needle seat, the seal protection must be manually removed; during the process of placing and taking the needle, the needle tip is always exposed and points to the palm of an operator, namely, the risk of finger pricking exists.
3) Because of the operation of installing the needle head and taking out the needle head, the gland of the blood sampling pen needs to be unscrewed and screwed for two times under normal conditions, which is very inconvenient.
4) If some patients forget to discard the needle after blood collection, the operation of the gland is reduced by two times, but the needle is extremely easy to use when the next time blood collection is performed, which brings immeasurable risks to the patients.
Disclosure of Invention

Thus, the risk of accidental scoring by the needle tip during the dynamic process of needle removal, installation, puncturing and needle discarding (i.e. the operation of removing the spent needle) of the patient is thoroughly eliminated.
Meanwhile, the blood taking needle head is completely separated from the driven firing pin mechanism, the synchronous reliability of the needle head in high-speed rebound is ensured, and the hidden danger of scratch caused by needle head disconnection is eliminated. Aiming at the defects that when a patient uses the blood taking needle, the operation is excessively complicated, the threat of the exposed needle point is received in the process, the needle is asynchronous when rebounding at a high speed, the old needle is reused and the like, the invention provides a brand-new and effective solution.

The needle-penetrating duct 6 is disposed along the axial direction of the substrate 2, the needle-penetrating duct 6 is a through hole, the front end opening of the needle-penetrating duct is located at the front end surface of the substrate 2, the rear end opening of the needle-penetrating duct is disposed at the rear section 23 of the substrate 2 and is connected with a chute 24 disposed at the rear section 23, the chute 24 is a strip-shaped groove penetrating through the top surface and the bottom surface of the substrate 2, the inner bottom surface of the chute is a surface inclined forward, and the chute is called a sloping shoulder 25.
The needle insertion 3 is inserted into the needle penetration hole 6 and can move back and forth along the needle penetration hole 6, a herringbone thimble 4 made of elastic materials is fixed at the rear end of the needle insertion 3, the thimble 4 is composed of three parts of a head part 41, a leg part 42 and a foot part 43, the head part 41 is the top end of the thimble 4, the leg parts 42 are two, the front ends of the leg parts 42 are free ends, the foot part 43 is the front end of the leg part 42, and the foot part 43 is wedge-shaped.
When the needle 3 is inserted into the needle-threading hole 6, the head (41) of the thimble 4 and the two leg parts 42 can move forward and are inserted into the sliding groove 24, when the thimble 4 is pushed forward, the wedge-shaped surfaces of the two leg parts 43 of the thimble 4 are pushed by the inclined shoulders 25 in the sliding groove 24 of the base plate 2 and slide out of the sliding groove 24 and overlap the top surface and the bottom surface of the rear section 23 of the base plate 2, and at the moment, the needle head of the needle 3 can penetrate through the front section 21 of the base plate 2 and be ejected out of the front port of the needle-threading hole 6 to penetrate into the skin of a patient.
The striker assembly 5 is composed of a striker 51 having a "door" shape, a top shaft 52 and a coil spring 53 fitted over the top shaft 52, and when the striker 51 is not activated, the top shaft 52 and the coil spring 53 are placed in the spindle center body 8 of the spindle of the lancing test pen and are completely separated from the lancet needle 1 with a sufficient distance, which ensures that the ejector has a sufficient striking speed (no need to carry a needle at the time of impact, no need to overcome the needle inertia).
At this time, the coil spring 53 is in a stretched state, and after the spring releasing mechanism provided at the rear end of the top shaft 52 is activated, the coil spring 53 drives the top shaft 52 and the striker 51 fixedly coupled to the front end of the top shaft 52 to impact forward.
The firing pin 51 is composed of a top seat 511 and two side plates, the top seat 511 is fixedly connected with the top shaft 52, the side plates are arranged on the same side as the leg 42 of the thimble 4, an inner hook 512 protruding towards the other side plate is arranged at the front end of each side plate, and the distance between the two inner hooks 512 is slightly larger than the width of the head 41 of the thimble 4.
The spiral spring 53 is released, the ejector shaft 52 pushes the firing pin 51 to move towards the needle head direction at high speed, and the space between the two inner hooks 512 of the firing pin 51 is slightly wider than the head 41 of the ejector pin 4, so that the needle 3 is not triggered to move forwards when the inner hooks 512 on the firing pin 51 pass over the head 41 of the ejector pin 4. After a certain idle stroke, the top seat 511 of the striker 51 touches the "head" part 41 of the ejector pin 4 and pushes the needle 3 to forward punch to the limit position of the spiral spring 53 (that is, the needle of the needle 3 pierces the skin of the patient), the "foot" part 43 of the ejector pin 4 overlapped on the surface of the rear section 23 of the base plate 2 is tightly attached to and clamped on the inner side of the inner hook 512 on the striker 51 ejected by the spiral spring 53, at this time, under the restoring force of the spiral spring 53, the inner hook 512 clamps and pulls the "foot" part 43 to draw back the needle 3 and hide the needle 3 in the needle through hole 6 (see fig. 5).
In the present invention, preferably, in the whole process of drawing back the needle tip of the needle 3 from outside the needle-threading channel 6 into the needle-threading channel 6, the legs 42 on both sides of the thimble 4 are overlapped on the surface of the rear section 23 of the substrate 2, and both legs 42 of the thimble 4 are in an open state (see fig. 2) with parallel inner sides and herringbone outer sides. When the tip of the needle 3 is withdrawn back into the needle-threading channel 6 and the "foot" portion 43 is located in the chute 24, the two leg portions 42 of the ejector pin 4 are in an original state (see fig. 1) with parallel outer sides and V-shaped inner sides by means of their elastic restoring forces.
The thimble 4 and the firing pin 51 are made of elastic hard plastic or metal spring plates.
