Description

Blood collection pen structure

The invention relates to a blood collection pen structure, in particular to a blood collection pen for blood glucose screening, and the blood collection pen has the function of replacing the needle at the same time, that is, the needle can be smashed into the state to be fired.

Press, because diabetic patients need to pay attention to the blood sugar content and concentration of the body at any time, so the Metropolis carries with them the instrument or device for detecting blood sugar levels. When detecting blood sugar, a small amount of blood must be obtained through a blood collection needle to provide the instrument. Or device detection, the use of blood collection needle is by hand holding the blood collection needle, piercing the human skin to obtain the required small amount of blood, however, when the blood collection needle is used, the amount of blood obtained depends on the penetration The size of the human skin is too small to get the right amount of blood. If the penetration force is too large, it may cause pain to the user and even cause damage to the human body. The method is likely to cause pollution due to touching or contaminating foreign objects. It may not only affect the accuracy of blood glucose detection, but also cause bacterial infection when penetrating human skin due to contamination of bacteria. The lack of various kinds is often Where the user is ill.

Please refer to the Patent No. M482372 of the Republic of China on the "Structure of Blood Collection Pen" patent, which mainly includes a pipe body, a body, a pull piece, a movable seat, a set of body and a blood collection needle. Before collecting blood, Insert the blood collection needle into the movable seat, and pull the pull piece backward to drive the movable seat to the position of the fire. Finally, press the push button to instantly take the blood collection needle, so that the blood collection needle penetrates the skin and achieves the purpose of obtaining blood. And the adjustment of the sleeve can control the degree of penetration of the blood collection needle when striking the skin.

The above is a practical blood collection pen creation, which has the effect of quickly piercing the human body through the firing; however, the blood collection pen must be inserted into the blood collection needle in sequence, and the pulling member is pulled so that the blood collection needle is located at the position to be fired. And pressing the button and firing three steps to carry out a lot of blood Liquid screening is very inconvenient.

In view of this, the creator has been engaged in the development of related industries for many years, and has in-depth discussions on the problems faced by the existing blood collection pens, and actively seeks solutions. After long-term efforts and research, he has finally succeeded in creating a kind of The blood collection pen structure for blood glucose screening, and the blood collection pen has the function of replacing the needle at the same time, and then licking the needle into a state to be fired.

The invention relates to a blood collection pen structure, which is a blood collection pen for blood glucose screening, and the blood collection pen has the function of replacing the needle at the same time, that is, the needle can be smashed into a state to be fired.

In order to achieve the above-mentioned creative purpose, the "blood-lancet structure" of the present invention comprises a main body, an outer cover, a sley, a firing spring and a button. The main system is a pipe body, and one end of the main body is for the outer cover to be docked. In the open state, one end of the outer cover has a needle outlet for the blood collection needle to pass through, and the first inner positioning point and a second positioning point are arranged inside the main body, and the first positioning point is opposite to the needle outlet. The second positioning point is a positioning point after the firing, and the one end of the sling is disposed inside the main body, and the sley corresponds to the needle side. Forming a sleeve for the blood collection needle, the side of the socket is formed with a spring piece for selecting a slide buckle at the first positioning point or the second positioning point, the button is disposed on one side of the main body, and the button has Once inserted into the main body and corresponding to the first positioning point, and the releasing end of the elastic sheet and the first positioning point buckle effect is released; thus, after the outer cover is removed from one end of the main body, the blood collecting needle can be set in the sley At the mouth, and at the same time as the setting The seat is inwardly contracted and synchronously compresses the firing spring. When the shrapnel corresponds to the first positioning point, it is locked with the blood collecting needle to be restricted to the position to be fired, and the outer cover is reinstalled at one end of the main body to complete the blood sugar detection. The front work; when the button is pressed, the release end pushes the spring to release the restriction from the first positioning point, and the cavity is driven by the firing spring to puncture the blood collection needle to the end of the needle.

The main system has a guide rail for sliding back and forth of the button, and the inner portion of the socket has an inner groove which is electrically connected to the sleeve, and the inner groove side has a partial open state, and the button has a protrusion extending into the inner groove. Push the segment.

The inside of the main body is provided with a partition plate, and the firing spring is elastically biased to one side of the partition plate. The main body is elastically coupled to a return spring on the other side of the partition plate, and the cavity base has a passing spring and a partition plate. And the pull rod of the return spring, and the pull rod is buckled at the end end of the return spring end type.

The foregoing main system includes a set of inner collars disposed at an open end thereof, and the first positioning point and the second positioning point are formed on the inner collar, and the inner collar is formed with at least one guiding track in the inner diameter system. The shank is placed on the inner collar, and the shank is formed with at least one rib corresponding to the guiding rail at the outer diameter.

The cavity seat defines a strain groove in the sleeve section for facilitating expansion of the sleeve size.

It can be seen from the above-mentioned creation content that the "blood collecting pen structure" of the present invention can position the blood collecting needle at the position to be fired while replacing the blood collecting needle with the pressing force, and replace the blood collecting needle with the to-be-fired pull compared with the conventional blood collecting pen. For the two steps, the invention can indeed eliminate the formalities of the quarantine personnel and effectively improve the medical operation speed of a large number of blood glucose screening; therefore, the invention can be said to be a practical and progressive creation, which is quite worthy of the industry. Promote and publicize to the public.
