The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The following detailed description of the embodiments of the invention is provided.

A needle-prick extraction integrated device for detecting genetic risk genes of andrological tumor is shown in figures 1 to 3 and comprises a device cylinder structure, wherein the device cylinder structure comprises a sampling cylinder body 1 and an adjusting cylinder body 2 arranged at the lower end of the sampling cylinder body, and the adjusting cylinder body is screwed at the lower end of the sampling cylinder body. A piston 3 is arranged in the sampling cylinder, a puncture needle 4 is fixed at the lower end of the piston, a sampling rod 5 is fixed at the upper end of the piston, and a pressing handle 6 is arranged at one end of the sampling rod, which extends out of the sampling cylinder.

An elastic part 7 is arranged between the pressing handle and a seal head 8 at the upper end of the sampling cylinder body, and the puncture needle is kept to be contracted in the device cylinder structure under the normal state by utilizing the elastic part; the lower end of the adjusting cylinder body is provided with a liquid inlet 9, and the inner diameter of the liquid inlet is larger than the diameter of the puncture needle.

To facilitate the aspiration of the blood sample, the length of the loading port is typically 1-5 mm. In order to ensure absolute safety and hygiene of the device, a protective cap 10, which covers the liquid inlet portion, may be removably mounted on the lower end of the adjustment barrel. The protective cap is taken off before use, and the protective cap can be mounted after use, so that blood samples are prevented from overflowing. Of course, the sample does not flow out of the cavity of the cartridge structure of the device without squeezing the press handle. Meanwhile, the condition that the pricking pin is easy to hurt people after being used and in the waste recycling process is also avoided.

In an alternative embodiment, the adjusting cylinder is screwed on the lower end of the sampling cylinder, and the lower end of the sampling cylinder is of an open structure. The sampling cylinder and the adjusting cylinder together form a cavity for storing samples. When the pressing handle is pressed down, the puncture needle extends out and punctures the skin, the puncture needle is recovered together with the piston under the action of the elastic piece after the hand is loosened, when the blood drops seep out, the liquid inlet is aligned with the blood drops, the sampling rod is properly pulled outwards by the pressing handle, the piston continues to move, and the blood drops seeping out of the skin can be gradually sucked into the device cylinder.

Typically, a seal is provided between the adjustment barrel and the sampling barrel to maintain the seal therebetween. For example, the sealing element can be a sealing ring arranged on the inner wall of the adjusting cylinder or the outer wall of the sampling cylinder, when the adjusting cylinder is screwed, the screwing length of the adjusting cylinder and the sampling cylinder is changed, and the stroke of the puncture needle is fixed when the pressing handle is pressed down, so that the length of the puncture needle extending out of the liquid inlet can be changed by adjusting the screwing length of the adjusting cylinder and the sampling cylinder, the length of the puncture needle penetrating into the skin of a human body can be effectively controlled, the reliability is high, and the requirements on the working experience and the operation proficiency of an operator are low.

It should be noted that, because the device is generally a disposable device, and the requirements of stress and sealing performance are different from the sealing performance in the mechanical industry field, the sealing effect can be achieved without a special sealing structure, for example, a sealing ring is used for sealing, and a groove for installing the sealing ring is arranged on the adjusting cylinder or the sampling cylinder, so that the sealing ring can be firmly installed and can play a sealing role.

Above-mentioned pressure handle surface is equipped with anti-skidding line or anti-skidding granule, and the sample section of thick bamboo outer wall is equipped with anti-skidding line or anti-skidding granule, can effectively increase frictional force, the operation of being convenient for. In addition, in order to facilitate the observation of the interior of the device barrel structure, the sampling barrel and the adjusting barrel can be made of transparent materials, such as PVC, PET, ABS and the like.

The elastic piece adopts a spring sleeved on the sampling rod, one end of the spring is propped against the lower surface of the pressing handle, and the other end of the spring is propped against the seal head.

In an alternative embodiment, the end socket is detachably mounted on the upper end of the sampling cylinder, specifically, the end socket comprises a baffle part 11 and a connecting cylinder part 12, the baffle part is arranged on the upper end of the connecting cylinder, and the lower end of the connecting cylinder part is in threaded connection with the upper end of the sampling cylinder. The baffle part is provided with a via hole for penetrating the sampling rod. To facilitate assembly of the device, the push handle may be threaded onto the end of the thief rod.

It should be noted that, in order to avoid that the spring pulls the pressing handle after the sampling rod is pulled outwards to suck the blood sample and the mistaken driving piston moves downwards to extrude the blood sample, during the actual assembly, at least one end of the spring is in an unfixed state, that is, the upper end of the spring is not fixed with the lower surface of the pressing handle or/and the lower end of the spring is not fixed with the baffle part of the sealing head. The structure design form can utilize the spring to keep certain supporting acting force, when the spring is extruded, the front end of the puncture needle extends out of the liquid inlet, when the pressing handle is not pressed (when hands are loosened), the spring recovers deformation, the pressing handle is upwards jacked up, and then the puncture needle is retracted into the device barrel structure, so that people are prevented from being injured. When drawing the blood sample, only need outwards draw the thief rod with the help of pressing the handle can, the spring can not form the pulling force to pressing the handle, promptly, when drawing the blood sample, this device is similar to the syringe needle tubing.

The invention has reasonable structure and design, when a blood sample is extracted, the pricking pin can be punctured by utilizing the part of the pricking pin which extends out of the liquid inlet by only pressing the pressing handle down to extend the pricking pin, when the blood flows out, the hand is released, the elastic piece recovers deformation to retract the pricking pin, and the pressing handle pulls the sampling rod outwards to absorb the blood sample, so that the operation is very convenient, the pricking and the sampling are completed on one device, the working efficiency is high, the pricking pin cannot accidentally injure people, and the safety is good. In addition, the axial position of the adjusting cylinder body relative to the sampling cylinder body can be adjusted according to the use requirement or the actual condition (such as fat content, body state and the like) of the person to be measured, the adaptability is improved, the operation difficulty is low, and the using effect is good.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
