Hammam’s version has the words “He took out the blood by pressing with his fingers”.

Abu Dawud said this tradition has been narrated by the people of Basrah who alone are its transmitters.
Sunan Abi Dawud Book 11, Hadith 33
← Previous Hadith The Messenger of Allah (SWAS) offered the noon prayer at Dhu al-Hulaifah. He then sent for a camel and made incision in the right side of its hump ; he then took out the blood by pressing it and tied two shoes in its neck. He then rode on his mount (camel) and reached al-Baida, he raised his voice for the talbiyah for performing Hajj.

Sunan Abi Dawud Book 11, Hadith 32 Next Hadith → Al-Miswar bin Makhramah and al-Marwan said the Messenger of Allah (SWAS) proceeded in the year of al-Hudaibiyyah (to Makkah). When he reached Dhu al-Hulaifah, he tied (garlanded) something in the neck of the sacrificial camel (which He took along with him), and made incision in its hump and put on Ihram.
