Description

Bloodletter{Tool of Depletion}

The present invention relates to a lancer, and more particularly, to a lancer, in which a disposable lancer is easily loaded without removing the cap from the outside of the lancer body, and the cap part of the lancer is removed and used in the loaded state, thereby preventing pain and secondary infection caused by the lancer sting that may occur when the lancer is initially installed or when the used lancer is replaced.

In general, a lancet is attached to a lancet and is used to instantly penetrate a thin needle into the skin to collect blood, and the collected blood is used for various tests such as blood sugar test or blood type test.

The needle of this lancet instrument is used repeatedly after collecting blood from the patient's skin, disinfected, and treated as it is exposed, so that the person performing the test (doctor or nurse) is stabbed during the patient's examination or retrieved. Because of this, lancets that can safely and hygienically collect blood have been developed because they may be infected with an unexpected disease performed during the examination.

Most lancing needles have a protective tip that protects the needle part, and the needle is exposed when the protective tip is removed during use.

These bloodletters are widely used for checking blood sugar, etc. for diabetic patients in hospitals as well as at home.

It is fixed to the rear end of the body 10' and has a guide hole 51a through which the operating rod 22 is guided. It is divided and assembled from the outside of the guide fixing cap 51 in a form surrounding the guide fixing cap, and is installed to be movable up and down from the guide fixing cap, and a loading cap 52 having a hook part 52a for hanging and supporting the operating rod 22 is formed inside the loading cap 52, and a loading spring provided on the inside of the loading cap 52 and on the outer circumference of the guide fixing cap 51 to give elasticity to the loading cap when the loading cap moves backward ( 53).

The action according to the use of the bloodletting machine of the present invention configured as described above is as follows.

First, as shown in FIGS. 1 and 7, the blood lancer according to the present invention is basically used by inserting the lancer L into the fork 21a of the holder parts 20 and 20' located in the inside of the first pencil stand 12 constituting the body 10 or the mounting hole 12b formed in the body 10', and mounting it when replacing with a new lancer needle. When the new lancer L is pushed into the fork 21 through the incision groove 12c cut in one direction, the used lancer is discharged from the opposite side, and the lancer is quickly replaced.

That is, the lancer L is inserted into the incision groove 12c without removing the cap part L2 protecting the needle L1 in a state in which it is integrally manufactured, and the used lancer needle is pushed out in the other direction and discharged, so that the used lancer needle can be used without touching it again.

This provides an advantage in preventing secondary infection due to needle prick of the lancer compared to the conventional method in which the lancer is inserted into the lancer, the cap is removed, and then the lancer cap is combined and used.

As described above, if the lancer is loaded with the lancer and the cap is removed, since the pointed end of the needle is located inside the needle, it can be used safely without a needle sticking phenomenon in handling the lancer.

As described above, when the bloodletter shown in FIG. 1 is used, when the bloodletter L is mounted on the pressure plate 31 protruding from the top of the second pencil rod 14, the pressure rod 33-side axis pin 35 provided therein is caught in the loading groove 14b of the second pencil rod 14, and the first spring 32 and the second spring 34 are pressed. .

Both ends of the shaft pin 35 caught in the loading groove 14b are formed in a state in which the loading groove formed on the front surface of the second pencil stand 14 is opposed to each other, and the diamond-shaped guide hole 31a formed on the side of the pressure base 31 also penetrates the shaft pin 35 in an opposite shape to maintain a state in which it is caught in the loading groove 14b.

In the above state, as the pressure base 31 advances, the shaft pin 35 contacts the inclined portion of the guide hole 31a and is momentarily released from the loading groove 14b. At the same time, the pressing force applied to the first spring 32 is momentarily released, and the shaft pin 35 is separated from the loading groove 14b toward the longitudinal direction of the second pencil bar 14 and is momentarily attached to the striking rod 33 impact is exerted.

Here, the striking rod 33 strikes and advances the end of the actuating rod 22 of the holder part 20 in front of it, so that the tip of the needle L of the lancer L attached to the fork 21a of the holder member 21 connected to the actuating rod 22 generates a striking action in which the needle L1 instantaneously protrudes to the tip of the intrusion 12a and moves backward. blood is drawn

That is, when the bloodlet machine 100 of the above type is released from the cuff 31, along with the backward movement of the cuff 31, the shaft pin 35 is caught in the loading groove 14b again by the inclined portion of the guide hole 31a and returns to the initial state of being supported while retracting.

For reference, the shaft pin 35 caught in the loading groove 14b is rotated halfway by the front and rear inclined parts of the guide hole 31a at the time of momentary departure from the loading groove 14b by the diamond-shaped guide hole 31a, and the forward strike is performed at the same time, and is caught at the longitudinal end of the loading groove 14b. The blow of the bloodletting needle (L) is made.

Meanwhile, as described above, in the bloodletting machine 100' of FIG. 7, when the loading cap 52 provided on the upper side of the body 10' is pulled and released in a state in which the bloodletting needle L is mounted on the holder member 21 on the holder part 20' side through the mounting hole 12b and the cutout groove 12c on the body 10' side, the hook 21c of the holder part 20' (10 ') It is in a state of being loaded by being caught between the hitting control unit 13 side locking holes 13b provided on the side.

The loading cap 52 is in a state where the loading spring 53 inside the loading cap 52 is compressed and restored again, and at this time, the coil spring 23 provided on the outer circumference of the operating rod 22 inside the body 10' is compressed.

Since the actuating rod 22 penetrates the guide fixing cap 51 and is caught on the hook part 52a of the loading cap 52, the holder part 20' through the actuating rod is pulled in a generally backward state until the hook 21c is caught between the hooking slots 13b.

When the push button 40 is pressed in the above state, the push protrusion 42 formed on the rear side of the push button pushes the hook 21 c to space it apart between the hook holes 13 b, and at the same time, an instant blow is made by the restoring force of the coil spring 23 so that the skin of the subject close to the invasion 12 a on the body 10 'side can be instantly stabbed and shaped.

As a result, in the blood lancer 100, 100' according to the present invention, the cap part of the lancer 100, 100' is mounted on the lancer in a state where the cap part of the lancer is not initially removed, and then the cap part is removed in a state in which the blow is prepared, and blood is collected by hitting the lancer with the same striking operation of the lancer. , After use, it is replaced by pushing the holder part with a new lancet and pushing it outward, so as mentioned above, a separate protective cap is not required, and the hassle of opening and closing the protective cap is eliminated.
