Description

A cardiovascular interventional bolus device

technical field

The utility model belongs to the field of medical devices, in particular to a cardiovascular interventional bolus device.

Background technique

Cardiovascular interventional therapy is a common method for diagnosing and treating cardiovascular diseases. In the process of cardiovascular interventional therapy, it is necessary to inject media such as contrast agents into the blood vessels to locate them by X-ray during surgery. A bolus is often used for injection. The structure of the bolus is similar to that of an ordinary syringe. Because the medium is relatively viscous and the handle of the bolus is thin, medical staff can only rely on the muscles of the palm to exert force, so it is difficult to grasp the strength. , affects the treatment, for this reason people developed a bolus device, such as a cardiovascular interventional bolus device disclosed in the Chinese patent application number 201620789198.0 and the cardiovascular intervention therapy device disclosed in the Chinese patent application number CN201020701352.7 These patents are driven by motors to reduce physical exertion, but the commonly used interventional bolus devices are mostly disposable. The structures of these two types of boluses are complicated, and the operation steps are increased, which is easy to cause errors. Therefore, A cardiovascular interventional bolus device is needed, which can reduce the physical exertion during the cardiovascular interventional bolus injection and improve the bolus injection efficiency.

Detailed ways

The technical solutions of the present invention are further described below, but the scope of protection is not limited to the description.

As shown in Figures 1 and 2, a cardiovascular interventional injection device includes a base 1, a fixed cylinder 2, a pressure block 3, and a syringe 4. The lower part of the fixed cylinder 2 is connected to the upper part of the base 1, and the syringe 4 is sleeved on the fixed cylinder. In the cylinder 2, the two ends of the fixed cylinder 2 are provided with guide pipes 5. The guide pipes 5 are connected with the fixed cylinder 2 through the connecting block, and the guide pipes 5 are perpendicular to each other. The lower part of the pressure block 3 is provided with a guide rod 6. 3 is connected with the guide tube 5 through the guide rod 6, and the lower part of the pressure block 3 is connected with the piston rod of the syringe 4, and the two ends of the pressure block 3 are provided with pressing handles 7.

When injecting the contrast medium, first use the syringe 4 to inhale the contrast medium, then insert it into the fixed cylinder 2, connect one end of the hose 11 to the barrel of the syringe 4, and then insert the guide rod 6 on the pressure block 3 into the guide tube 5, and put the counterweight 10, and place the whole device on the table of 60cm to 80cm. After the preparation is completed, insert the needle at one end of the hose 11 into the human blood vessel, and fix it with adhesive tape. Since the contrast agent is viscous , and the cross-sectional area of the needle tube is small, and the resistance during injection is relatively large. When injecting, hold the pressing handle 7 with both hands, move the center of gravity of the upper limb forward, press on the pressing handle 7, and press down the piston rod of the syringe 4 by the force of the arm. , to complete the operation of bolus injection of contrast agent, the traditional syringe injection can only use the muscles of the palm to exert force. The device can use the muscles of the upper limbs and the arms to exert force, and the force is greater, which can reduce the fatigue during bolus injection and improve the bolus injection efficiency.

An opening 8 is provided on one side of the fixed cylinder 2 , and the length of the opening 8 is 1/2 to 4/5 of the length of the fixed cylinder 2 . The situation in the syringe 4 can be observed through the opening 8 during bolus injection, which is convenient for operation.

The pressure block 3 is provided with a connecting rod 9, and the connecting rod 9 is provided with a counterweight block 10. The counterweight block 10 is connected with the pressure block 3 through the connection rod 9, and the gravity of the counterweight block 10 is used to generate a downward pressure and push the bottom. Physical consumption during injection.

The lower part of the syringe 4 is provided with a hose 11, one end of the hose 11 is communicated with the barrel of the syringe 4, the other end is pierced from the base 1, and a needle is provided at the end, and the contrast medium is injected into the human blood vessels through the hose 11 During the bolus injection, please shake the whole device without moving the needle, which improves the safety.

The lower part of the pressure block 3 is provided with a groove 12, and the pressure block 3 is connected with the piston rod of the syringe 4 through the groove 12. The piston rod of the syringe 4 is stuck in the groove 12 to prevent the piston rod from slipping off during injection.
