Description

Post-cerebrovascular intervention puncture position pressing device

Technical Field

The invention relates to the technical field of medicine, in particular to a puncture position pressing device after a cerebral vascular intervention operation.

Background

The interventional therapy in cerebral blood vessel utilizes the operation technology of catheter, and under the support of digital subtraction angiography under the control of computer, the operation technology of catheter in blood vessel is adopted to diagnose and treat the pathological changes of human neurovascular system by the methods of selective angiography, embolism, dilation forming, mechanical clearing, drug delivery and the like. Therefore, the affected limb of many cerebrovascular diseases is in a straightening and braking state after the operation and is kept for 8 hours, and the rice bag is usually used for pressing the puncture part to prevent microbial contamination or blood seepage caused by improper movement to the puncture part or the indwelling tube and the like.

Dressing observation and nursing are carried out on a puncture part after operation, whether the binding part is shifted or not needs to be observed at any time, the formation of wrong extravasated blood and hematoma exists under the skin, the change condition of the hematoma size is observed, whether the slipping condition of a braking rice bag at the puncture part exists or not is observed, and whether the pressing part of the rice bag is correct or not is observed, so that the occurrence of complications such as bleeding, hematoma, infection, pseudo aneurysm and the like at the puncture part after operation is effectively prevented, and the time of a large number of medical staff needs to be consumed.

When a patient lies on a nursing bed, the area needing to be pressed is located beside the nursing bed, and the area needing to be pressed has a certain range limitation, so that the rice bag is very difficult to use, the patient needs to lie on the side for matching, and the observation is needed from time to time after the patient presses the designated area, so that the operation is complicated, and the waste of human resources is caused.

However, in the postoperative observation and nursing process, the rice bag is used for pressing the puncture part, so that the workload of medical workers is increased due to the fact that the rice bag easily slips off, the operation of pressing the pressing part with different force levels is inconvenient by changing the weight of the rice bag, and the optimal recovery effect is influenced by the fact that the weight of the rice bag cannot be accurately controlled.

In the later pressing process, the pressing part is often required to be compressed by ice compress (blood vessels can be contracted, the local blood flow speed is slowed down, and the bleeding incidence rate is reduced); sometimes, the compression part needs to be compressed by hot compress (the excitability of pain nerve can be reduced, local blood vessels can be expanded, and blood circulation can be improved), and an auxiliary device needs to be additionally arranged to generate heat or cool, so that the operation is complicated, and the maintenance is troublesome.
