The present invention is directed to solving the above-mentioned problems and disadvantages of the prior art by providing a depth-adjustable safety lancet.
The technical problems solved by the invention can be realized by adopting the following technical scheme:
The utility model provides a degree of depth adjustable safety blood taking needle, includes the body, be provided with the needle point of fixing on the needle file in the body, the tail end of body is provided with the top button, the top button passes through the mounting and is connected with a release locking piece, release locking piece and one set up the joint spare cooperation in the body is connected, release locking piece pass through the connecting rod with the needle file is connected just the lateral part of release locking piece is provided with lateral part button, its characterized in that the front end of body is provided with and is used for adjustable the regulator of needle point puncture degree of depth, the regulator with the front end of body is connected.
In a preferred embodiment of the present invention, a safety pin is provided on the tube body to limit the movement of the needle mount.
In a preferred embodiment of the invention, the regulator is connected with the front end of the pipe body through threads, and the front end of the pipe body is provided with graduation marks.
In a preferred embodiment of the invention, the top button is provided with a spring member.
In a preferred embodiment of the present invention, a spring member and a spring stopper are further disposed in the tube body, the spring member is connected with the connecting rod, and the spring stopper is fixed on an inner wall of the tube body and is disposed parallel to the connecting rod.
Due to the adoption of the technical scheme, the invention has the beneficial effects that: the invention can adjust the penetration depth of the blood taking needle for different people through the regulator, has extremely short penetration time, reduces pain feeling during blood taking, and has the advantages of simple structure, convenient operation and use, stable performance, safety and reliability.
Drawings
In order to more clearly illustrate the embodiments of the invention or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the invention, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a schematic view showing the structure of a depth-adjustable safety lancet according to the present invention.
Detailed Description
The invention is further described below in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the invention easy to understand.
Referring to fig. 1, a depth-adjustable safety lancet comprises a tube body 10, wherein a needle tip 11 is arranged in the tube body 10, the needle tip 11 is fixed on a needle seat 12, a top button 20 is arranged at the tail end 10b of the tube body 10, a spring element 20a is arranged on the top button 20, and the spring element 20a facilitates telescopic movement of the top button 20. The top button 20 is connected with a unlocking member 40 through a fixing member 30, the unlocking member 40 is connected with a clamping member 50 arranged in the tube body 10 in a matched mode, the unlocking member 40 is connected with the needle seat 12 through a connecting rod 60, and a side button 41 is arranged on the side portion of the unlocking member 40. The unlocking member 40 and the locking member 50 can fix the needle tip 11 inside the tube body 10, preventing the needle tip 11 from extending outside the tube body 10.
The distal end 10a of the tube 10 is provided with a regulator 70 for regulating the penetration depth of the needle tip 11, and the regulator 70 is connected to the distal end 10a of the tube 10. The adjuster 70 is connected with the front end 10a of the pipe body 10 through threads, and the front end 10a of the pipe body 10 is provided with scale marks 10aa. The scale mark 10aa is convenient for the regulator 70 to be able to regulate according to the depth of blood collection of the crowd.
The tube body 10 is provided with a safety bolt 80 for limiting the movement of the needle holder 12, and the safety bolt 80 is arranged on the needle holder 12 and is used for fixing the needle holder 12 from moving.
The pipe body 10 is also internally provided with a spring piece 61 and a spring limiting block 13, the spring piece 61 is connected with the connecting rod 60, the spring limiting block 13 is fixed on the inner wall of the pipe body 10, and the spring limiting block 13 is arranged in parallel with the connecting rod 60.
The working principle of the invention is as follows:
According to the depth of penetration of the crowd, the safety bolt 80 can be removed through the regulator 70, then the top button 20 and the side button 41 are pressed simultaneously, at this time, the fixing piece 30 below the top button 20 moves downwards, the side button 41 pushes the unlocking piece 40 to move inwards, the unlocking piece 40 is separated from the clamping piece 50, and the needle seat 12 can move up and down to drive the needle point 11 to take the blood by taking the needle.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
