The present invention relates to a self blood sampling device, wherein an absorbent layer container (10) is detachably coupled to a lower portion of a case (100), and a plurality of needles (21), which are injection needles that penetrate into the skin, are disposed on the upper portion of the absorbent layer container (10). A needle bundle 20 is installed, and a pressing portion 30 for moving the needle bundle 20 to the lower portion is installed on the upper portion of the needle bundle 20.

In addition, the absorbent layer container 10 is characterized in that the absorbent layer 11 installed below the needle bundle 20 to capture the blood generated by the needle 21 is embedded.

In addition, in the push part 30, a push rod 32 is coupled to the lower part of the upper button 31, a compression coil spring 33 is installed on the outer periphery of the push rod 32, and the push rod 32 ) is characterized in that two are installed.

The present invention will be described in detail with reference to the accompanying drawings.

It is an operation diagram before and after moving the part.

The present invention is a tool that allows a user to take a blood sample by himself. Recently, thanks to technological advances in related fields, many diseases can be diagnosed with a small amount of blood sample. A user can purchase this blood sampling device at a pharmacy, etc., collect blood on their own, send the collected blood sample to a designated laboratory (diagnosis center), and use the blood sample collected there as an analysis device to diagnose a planned disease.

The self-lanceolate device of the present invention is a needle bundle composed of a plurality of needles 21, which are injection needles that penetrate into the skin, in which the absorbent layer container 10 is detachably coupled to the lower part of the cylindrical case 100, and the upper part of the absorbent layer container 10 20 is installed, and a pressing part 30 for moving the needle bundle 20 to the lower portion is installed on the upper portion of the needle bundle 20.

A barrier rib restricting the upper movement of the needle bundle is formed at the lower portion of the case, and the case is divided into an upper case in which the pressing unit moves up and down and a lower case in which the needle bundle moves up and down with the barrier rib interposed therebetween. On the other hand, a locking protrusion is formed at the lower end of the outer circumference of the pusher, and a locking piece protrudes toward the inner center in the middle of the case, so that when the pusher rises, the locking protrusion of the pusher is caught on the locking piece to limit the upward distance of the pusher do.

In the push part 30, a hollow cylindrical push rod 32 is coupled to the lower part of the upper flat button 31, and a compression coil spring 33 is installed on the outer periphery of the push rod 32, The lower end of the push rod is coupled to the needle bundle fixing plate coupled to the upper portion of the needle bundle. A needle bundle fixing plate is installed on the upper part of the needle bundle, and on the upper surface of the needle bundle fixing plate, an annular projection is formed in a concentric circle spaced apart from the center and the center, respectively, and the lower end of the push rod is inserted and coupled between the projections. As an example, two push rods 32 are integrally installed side by side. The needle bundle has a needle fixing portion made of PMMA coupled to the lower portion of the needle bundle fixing plate on the upper surface, and the upper end of the needle is fixed to the needle fixing portion. The needle fixing part is installed at a distance from the lower absorbent layer so that there is no risk of the needle being inserted into the case and protruding outward when the push rod is positioned at the top. Soon, the length of the smile is longer than the length of the needle.

The absorption layer container 10 has an absorption layer 11 installed below the needle bundle 20 to capture blood generated by the needle 21. A hole for passing a needle is formed in the absorbent layer. A protrusion for installing the absorbent layer container 10 is integrally formed inside the lower part of the case, and a hole through which a needle can protrude downward from the lower surface of the case and through which collected blood can be absorbed into the absorbent layer is formed.

In other words, the self-lanceolate device of the present invention largely consists of 1) a press to move the needle for blood collection, 2) a bundle of needles (injection needles) that invade the skin, and 3) an absorbent layer that captures the blood generated by the needle. do. By adopting a microneedle to collect blood in a minimally invasive manner, it is characterized by minimal invasiveness, painlessness, minimal trauma, and high efficiency. The needle (injection needle) bundle is made of stainless steel.

The absorbent layer (Polyurethane foam) bleeds from the skin penetrated by the needle.

Blood seeps into the absorbent layer. The shape of the lower part leading to the absorbent layer is gradually narrowed so that the blood can permeate well into the absorbent layer.

The entire lower part is finished with a sealing material with elastic sealing power such as silicone so that the sampler can be well fixed on the skin surface.

At the outer periphery of the pressing part, a guide that helps the pressing part move straight to the bottom is formed in a groove shape in the vertical direction. Correspondingly, a guide is formed in a protruding shape on the inner surface of the case. And the present invention attaches a sticker for maintaining the hygiene of the microneedle when the product is shipped.

When using the collector, use it after removing the sticker.

As another embodiment, a weight sensor such as a conventional load cell is installed in the lower part of the case, and a controller is installed to receive a signal from the weight sensor and display it on a display, so that the weight of absorbed blood can be known after blood collection.

Therefore, in the present invention, the absorbent layer container is detachably coupled to the lower part of the case where the pressing part and the needle bundle are installed, so that blood collection is performed conveniently, safely and quickly, and the absorbent layer container containing the blood sample is easily transferred to a designated laboratory or diagnostic room. There is a remarkable effect that can be transferred.
