Infant heel blood collector

Abstract

The invention discloses an infant heel blood collector. A sliding block is fixed by a trigger key and is locked by a safety bolt in an initial state, and an elastic part is in the state of storing elastic potential energy. When the infant heel blood collector is used, the safety bolt is pulled out, sliding block locking can be relieved by slightly pressing the trigger key, the elastic potential energy stored by the elastic part is released instantly, the elastic potential energy drives the sliding block to slide in a sliding cavity so as to drive a connecting rod to rotate with a rotating pin as a center, a second sliding pin slides in an arc-shaped sliding groove, a third sliding pin on a driving seat slides from the upper end to the lower end of a sliding groove II and returns to the upper end so as to form a one-time reciprocating action, a blade extends from a blade outlet along an arc-shaped trajectory one time, and infant heel cutting and blood collecting actions are achieved. The structure includes fewer structural parts, the transverse movement of the sliding block is converted into the arc-shaped moving trajectory of the blade through the connecting rod, and the infant heel blood collector has the technical advantages of being simple in structural principle, lower in cost and capable of accurately controlling the cutting depth and width of the blade and is suitable for large-range popularization and use in medical institutions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood sampler for infants' heels. Background technique [0002] As a common medical device, blood collection device is widely used in medical units for blood collection. There are two types of blood collection devices: needle-prick type and blade-scratch type. Among them, acupuncture is mostly used for blood collection from fingertips, and it is mostly used for adults or older children because of its pain. Due to the clearer pain, the blade slashing method is mostly used for blood collection of the heel of the newborn. At present, there are a variety of commonly produced baby heel blood collection devices on the market, most of which are produced by foreign manufacturers, and the cost is relatively high; some domestic manufacturers also have the defect of high cost due to their complex structure. Therefore, the popularity of the infant heel lancet still needs to be i...
