Description

Technical Field

[0001] The present application relates to the technical field of blood sampling devices, and in particular to a baby heel blood sampling device that can be operated with one hand. Background Art

[0002] Newborn heel blood screening refers to an examination that collects blood from the heel 72 hours after the baby is born. It is mainly aimed at diseases with high incidence, no obvious symptoms in the early stage but with positive laboratory indicators, which can be diagnosed and treated. At present, newborn heel blood sampling is generally achieved through two types of blood collection devices: one type of blood collection device is an ordinary peripheral blood collection device, which collects blood by acupuncture and is mainly used for fingertip blood collection; the other type of blood collection device is a heel blood collection device designed specifically for heel blood collection, which collects blood by cutting with a blade.

[0003] The prior art uses an independent locking component to prevent the baby heel blood sampler from being accidentally activated. To release the safety state, the lock needs to be pulled out. Another way is to release the safety state by twisting off the safety mechanism. For example, the application number is 2018209898057, and the patent name is a new type of heel blood sampler. When the blood sampler is in use, the limit lock is first pulled out, and the toggle switch is no longer in a stuck state. In the above prior art, it is necessary to use both hands to pull out the activation lock before blood sampling, and then grab the baby's heel for blood sampling. This process is relatively cumbersome and there is a possibility of accidental activation during the process. Utility Model Content

[0015] 1. When the blood collector is in use, the staff only needs to hold the shell with one hand, let the blood collection port of the shell contact the blood collection area of ​​the baby's heel, and then extend the thumb to press the safety buckle. Since the upper side of the safety buckle and the side wall of the toggle switch are easily detached, under the pressure of the thumb, one side of the safety buckle is separated from the side wall of the toggle switch, and then the safety buckle rotates at the contact point between the other side of the safety buckle and the side wall of the pre-firing groove, and finally the safety buckle falls from the shell, and then the toggle switch can be pressed to realize the blood collection process. Through the above operation process, the blood collector can be operated with one hand, which improves the convenience of operating the blood collector;
