Pericardiocentesis liquid extraction device for department of cardiology

Abstract

The invention relates to the technical field of liquid extraction devices, in particular to a pericardiocentesis liquid extraction device for the department of cardiology, which comprises a device main body comprising a syringe, wherein an injection head is fixedly mounted on one side of the syringe; and a sealing piston movably placed in the syringe, wherein the outer side of the sealing piston is tightly attached to the inner surface of the syringe, and one side of the sealing piston is connected with a transmission strip. According to the device, a clamping tooth plate, a toothed plate ring, a first rotating head and a first power rod are arranged, the first rotating head rotates to drive the toothed plate ring and the clamping tooth plate meshed with the toothed plate ring to move, and therefore the control method of the device is changed into the mode that the first rotating head is rotated to control the liquid pumping speed and the liquid pumping volume of the device; in this way, control through arm strength of medical staff is changed into control through finger strength, and the controllability of the medical staff on the device is improved due to the fact that fingers are flexible.

Description

technical field [0001] The invention relates to the technical field of liquid pumping devices, in particular to a pericardial puncture pumping device for cardiology. Background technique [0002] Pericardiocentesis is a diagnosis and treatment technique that directly penetrates the pericardial cavity with the help of a puncture needle. Pericardial puncture must be performed under aseptic technique, local application of procaine anesthesia, the puncture site should not be too deep, so as not to puncture the atrium, ventricle or puncture the coronary artery and cause a large amount of hemorrhage in the pericardial cavity. Patients with pericardiocentesis can understand the nature of pericardial effusion by testing the fluid in the pericardial cavity, and find out the cause of pericarditis according to the nature of pericardial effusion. Although pericardiocentesis has certain risks, it is a relatively safe method of diagnosis and treatment if it is carried out strictly accord...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pericardial puncture pumping device for cardiology to solve the traditional operation method proposed in the above background technology, which is to use a larger needle tube with a needle and an electrified device to perform more accurate positioning. , when pumping liquid, it is often necessary for the staff to hold the needle tube in one hand and pull the piston core back with the other hand to carry out negative pressure suction liquid. It is inconvenient to control the volume and pumping speed, which will easily lead to continuous changes in the pumping speed during pumping, and at the same time, it is impossible to accurately control the pumping volume, which will reduce the patient's sense of experience when receiving treatment, and even Substantial harm to the patient
