A blood collection needle and a continuous blood collection device

Abstract

The invention provides a blood taking needle. The blood taking needle comprises a shell body, a needle body and an ejection mechanism, wherein a hole-slot is formed in the shell body; the needle body and the ejection mechanism are arranged inside the shell body; the ejection mechanism comprises a trigger part; the trigger part corresponds to the position of the hole-slot, and is not protruded to the surface of the shell body. The invention further provides a continuous blood collection device. The device comprises a main body, a needle box and the blood taking needle, wherein the main body comprises a main body shell, a button, a slide block and a slide way; the slide block and the slide way are arranged inside the main body shell; an opening through which the blood taking needle passes is formed in the lower half part of the slide way; a push block extends out from the top of the slide block, and the slide block can slide along the slide way; a needle box insert hole is formed in the side surface of the main body shell; a first needle outlet and a second needle outlet are formed in the bottom of the main body shell, and are communicated with each other; a contact is arranged on the back of the button; when the blood taking needle reaches a working position, the contact is opposite to the trigger part. The blood taking needle and the continuous blood collection device can be used for effectively avoiding cross infection among different patients, are convenient for user operation, have few operation steps and are compact in structure.

Description

technical field [0001] The invention relates to the field of blood collection tools, in particular to a blood collection needle and a blood collection device. Background technique [0002] The blood collection devices currently on the market are mainly single-shot blood collection devices, which can be divided into two types: one is to use a blood collection pen to install a blood collection needle to collect blood, and then discard the blood collection needle; the other is to install a blood collection needle. The device is integrated and discarded directly after blood collection. Compared with the first blood collection device, the security needle is easy to use and has higher safety, which can effectively reduce accidental needle sticks before blood collection, and minimize the risk of infection among medical workers around the world during the operation of collecting blood samples. possibility. However, none of the above-mentioned blood collection devices can realize c...
