Description

Vacuum assisted auto-lancing device

The present invention relates to a vacuum automatic blood collection device, and more specifically, it is possible to collect blood in various operations regardless of the blood collection site, and it is not necessary to adjust the subcutaneous penetration depth of the blood collection needle every time. Vacuum is also applied to the force to reduce the fear and pain to the user relates to a vacuum automatic blood collection device that can be used comfortably.

In general, patients with chronic diabetes should have their own blood glucose tests at home every day to measure their blood sugar levels and manage their disease to maintain a constant blood sugar level. In order to perform the blood glucose test, blood must be collected. Usually, a small amount of capillary blood is collected by penetrating the skin of a body such as a finger with a disposable lancet, and then a blood glucose tester is mounted on the strip. Blood glucose levels are measured.

As described above, as a device for collecting blood, a lancing device has been mainly used. The blood collection device described above includes a lancet holder equipped with a disposable lancet, an end cap having a lancet and an end cap having a protruded attachment of the needle for skin penetration, and a spring and percussion mechanism providing skin penetration. It consists of. The blood collection device first separates the end cap from the blood collection device, and then attaches the lancet to the lancet holder while covering the end cap under the spring compression and closes the capillary, such as a finger, and presses the trigger switch to press the trigger switch. Trigger and penetrate the skin. At this time, the periphery of the skin is pressed to obtain sufficient capillary blood and capillary blood is applied to the strip of the blood glucose meter to measure the blood glucose level. However, the above-described method of collecting blood with capillaries has a problem that the most commonly used method or the patient must carry the blood collection device and a plurality of lancets together at all times.

In order to solve such a problem, Korean Patent Application No. 2000-55280 discloses a disposable auto-lancet incorporating a trigger mechanism, but such a disposable auto-bleeding needle has a portable lancing device. Although there is an unnecessary advantage, the production cost is increased, which not only burdens patients, but also general blood collection devices and disposable auto-acupuncture needles allow blood to be collected only in the human body, for example, fingers or toes, which have a large volume of capillaries. Significant pain is accompanied by nerve fibers distributed with capillaries at the same time, and there is a problem of fear for chronic diabetics who have to collect blood every day.

In order to solve the problems described above, a vacuum assisted device (vacuum assisted) that sucks blood by vacuum suction after penetrating the blood collection site having a relatively small distribution of capillaries and nerve fibers, for example, arms and thighs. lancing device) (US Pat. 6,152,942). This vacuum assisted lancing device removes the end cap, mounts the needle into the holder, inserts the end cap again, and then rotates only to the proper position on the ramp formed on the contact surface with the body. Adjust the depth of skin penetration. When the collection of needles is completed, the front of the instrument is in close contact with the skin and pressing the plunger at the rear enters the plunger, compressing the inner spring, and simultaneously opening the one-way valve to release the decrease of the internal air volume due to the spring compression to the outside. The blood pressure needle moves forward with compression of the plunger and prevents an increase in pressure, and when a certain position is reached, the trigger, the return spring and the trigger mechanisms are operated, and the blood needle penetrates and returns to the skin.

When the plunger is released after penetrating the skin, a vacuum (negative pressure) is formed inside the end cap while the compressed inner spring pushes the plunger out. At this time, the blood collection needle is removed from the skin together with the plunger. As such, when the plunger and the blood collection needle retreat, the skin is swollen by vacuum inhalation, and blood is collected. Then, the plunger is pushed again to remove the vacuum, and then the blood collection apparatus is removed from the skin.

However, the vacuum assisted lancing device described above, firstly, since the plunger must be pressurized to remove the vacuum after the blood collection is completed, when the blood needle connected to the plunger is advanced to the skin side and penetrates the skin again due to the user's mistake, There was a problem providing the cause.

Second, since the depth of penetration of the blood collection needle is determined by the slope of the end cap, it must always be checked when the end cap is mounted on the body, and thus, there is a problem in that the penetration depth is adjusted every time the blood is collected.

Third, the vacuum blood collection device pushes the plunger by hand to obtain the spring compression energy required to form the vacuum and at the same time the blood collection needle moves forward, so the force of pushing the plunger must be strong according to the strength of the spring to form a sufficient vacuum sound pressure. The patient felt a fear of skin pain, there was a problem that the psychology of resistance to the use of the device occurs.

Fourth, because the above-described vacuum blood collection device was developed for vacuum suction only, there was a problem that can not be used for fingers or toes, etc. in which capillaries are distributed a lot.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to be able to collect blood in a single operation in a variety of sites irrespective of the blood collection site, and adjust the subcutaneous penetration depth of the blood collection needle every time In addition to the needlessness and automatic triggering with a small force to reduce the fear and pain to the user provides a vacuum automatic blood collection device that can be used comfortably.

At this time, the second hook 722 formed on the mounting plate 720 is engaged with the first hook 536 formed on the swing plate 532 of the second percussion 530. When the plunger 710 is pressurized in this way, the user contacts the second vacuum forming hole 322 and the first vacuum forming hole 316 in a state in which the adhesive plate 632 of the end cap 630 is in close contact with the skin to be collected. When the user presses the operation switch 310 while closing, the air in the blood collection device 100 is closed and the first trigger 510 is operated first (see FIG. 6B). That is, the first operation period 312 is lowered to strike the first percussion protrusion 528, the hitting first percussion protrusion 528 is separated from the second incision groove 438 compressed lancet spring ( 516 is triggered to penetrate the user's skin and then return to rebound spring 520 again. At this time, the first percussion protrusion 528 separated from the second cutting groove 438 is disposed in the first guide groove 428 formed in the first stem 410. On the other hand, the triggering of the plunger 710 takes place almost simultaneously with the operation of the first trigger 510 (see FIG. 6A). Immediately after the first operating period 312 strikes the first triggering protrusion 528, the second operating interval 314 strikes the second triggering protrusion 540 of the second triggering unit 530, and the hitting agent The two cocking protrusions 540 rotate the pivoting plate 532. At this time, the first hook 536 of the swing plate 532 is loosened with the second hook 722 and the elastic piece 542 is compressed by the stopper 434 and the plunger 710 is compressed. 726 is conveyed to the side of the second chamber 214b. At this time, the second percussion 530 is returned by the elastic piece 542 compressed by the stopper 434. As such, when the plunger 710 and the first trigger 510 are relaxed (FIGS. 7A and 7B), the blood pressure is lowered in the blood collection device 100 while drawing blood from the blood collection hole formed by the lancet 522. As such, the user who has completed the blood collection to some extent opens the operation switch 310 to open the second vacuum forming hole 322 and the first vacuum forming hole 316 to distribute the air in the blood collecting device 100 to remove the vacuum. After the blood collection device 100 is detached from the skin, the blood glucose test strip 742 embedded in the fourth chamber 716b is taken out and the blood glucose test is performed.

As described above, the vacuum automatic blood collection device 100 according to the present invention may prevent the risk of double skin penetration by separating and operating the lancet 522 and the plunger 710 mounted to the first percussion device 510. In addition, it is possible to use only one of the lancet 522 and the plunger 710 alone is very easy to use repeatedly when you have committed a mistake and can be used for all blood collection areas such as finger and cuffs as well as simple It is automatically triggered by the operation of the operation switch 310 can reduce the fear of using the blood needle and there is an advantage that can be always through the skin at a consistent moment.

In addition, by adjusting the depth of subcutaneous penetration depth in advance with the adjusting screw 610, by combining the end cap 630, as well as to solve the trouble of having to adjust the depth of subcutaneous penetration every time like a conventional vacuum blood collection machine, as well as subcutaneous tissue damage. There is an advantage that can be prevented in advance.

In addition, the lower portion of the contact plate 632 formed on the end cap 630 is curved upward, so when the skin swells by vacuum suction, the skin is in close contact with the skin and presses the capillaries under the skin as a whole to squeeze the blood. With the vacuum applied to the penetrating portion, efficient blood collection is possible, and by simply opening and closing the first vacuum forming hole 316 and the second vacuum forming hole 322, the vacuum is formed and the vacuum is released. This can help prevent blood from splashing when removed.
