The invention provides a self-sealing bladder puncture fistulization assembly, and belongs to the technical field of medical auxiliary instruments. A self-sealing bladder puncture fistulization assembly comprises a tearable sheath, a needle core and a self-sealing mechanism, the tearable sheath is arranged on the outer side of the needle core in a sleeving mode, the self-sealing mechanism comprises a needle cap, a control button, a compression spring, a urinary catheterization hole, a needle cap far-end cavity and a needle cap near-end cavity, and the control button can move up and down in the needle cap; when the puncture needle is successfully punctured into the bladder to be in contact with urine, urine can be drained instantly to remind an operator of puncturing in place, other equipment or repeated puncturing is not needed, auxiliary injury is prevented, and the compression spring is used for compressing to form sealing during resting, so that the urine does not flow out. The self-sealing bladder puncture fistulization assembly is simple in structure, low in manufacturing cost and convenient to operate.
Description
technical field [0001] The invention relates to the field of medical auxiliary instruments, in particular to a self-sealing bladder puncture and fistula assembly. Background technique [0002] Clinically, cystocentesis is a common surgical procedure and is often used to treat patients with neurogenic bladder or urinary retention. Cystostomy usually chooses faster puncture and ostomy, and puncture and ostomy needles are also divided into traditional surgical kits that are sterilized and reused and disposable cystostomy components. In order to facilitate use and avoid cross-infection, disposable puncture and ostomy components have gradually become the mainstream. Chinese patent (application number: CN201120156121.7, application date: May 7, 2011) proposes a combined puncture ostomy assembly composed of an inner core and an outer sleeve; Chinese patent (application number: CN201320345218.1, application date : June 17, 2013) and Chinese patent (application number: CN2016212415...
