Negative-pressure drainage device for cardiovascular medicine

Abstract

The invention provides a negative-pressure drainage device for cardiovascular medicine, and relates to the technical field of medical apparatuses and instruments. The negative-pressure drainage device for the cardiovascular medicine comprises a negative-pressure drainage instrument and a solution storage device, wherein a negative-pressure generating device is arranged on the side wall of the negative-pressure drainage instrument and comprises a pressing handle, a spring piece, a connecting rod and a piston; the piston moves in a piston cavity; the right end of the piston cavity is communicated with the negative-pressure drainage instrument through a first one-way valve; the left end of the piston cavity is a handle moving cavity and a boss is formed at the connecting part; the spring piece is arranged between the boss and the pressing handle; a negative-pressure sensor is arranged in the negative-pressure drainage instrument; the lower end of the negative-pressure drainage instrument is connected with a pipe head through a drainage pipe; a flow sensor is arranged on the drainage pipe; a display is arranged on the surface of the negative-pressure drainage instrument; the solution storage bottle is connected with a connecting end cover through a thread in a sealed way; the upper end of the negative-pressure drainage instrument is connected with a connecting end cover; the connecting end cover is connected with a negative-pressure source; and a solenoid valve is arranged on the negative-pressure pipe. According to the invention, the negative-pressure source can be communicated through negative pressure starting to provide continuous negative pressure, the negative pressure value and drainage amount can be automatically regulated and convenience in use is realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure drainage device for cardiovascular medicine. Background technique [0002] In the current clinical practice of cardiovascular medicine, common drainage bottles are generally used for surgery. When ordinary drainage bottles are used, the negative pressure device needs to be connected separately. When there is a lot of drainage liquid, it is necessary to repeatedly create a negative pressure environment, which is cumbersome to operate. Aggravated the work intensity of medical staff, brought great trouble to medical staff. [0003] For example, Chinese Patent No. CN201220016221.4, an invention patent with a publication date of September 19, 2012, discloses a new type of negative pressure drainage device for cardiology. The utility model includes a drainage bottle, a drainage tube, a piston, a handle and a Liquid mouth, the drainage bottle is one-sided s...

When ordinary drainage bottles are used, the negative pressure device needs to be connected separately. When there is a lot of drainage liquid, it is necessary to repeatedly create a negative pressure environment, which is cumbersome to operate. Increased the work intensity of the medical staff and brought great trouble to the medical staff

[0003] For example, Chinese Patent No. CN201220016221.4, an invention patent with a publication date of September 19, 2012, discloses a new type of negative pressure drainage device for cardiology. The utility model includes a drainage bottle, a drainage tube, a piston, a handle and a Liquid mouth, the drainage bottle is one-sided sub-waist shape, the bottle wall is provided with a scale line, the middle part of the arc-shaped bottle wall of the drainage bottle is provided with a cylindrical recessed area with a smooth inner surface, and the recessed area The inner wall is smooth and opens inwardly. The piston is closely combined with the inner wall of the recessed area and can slide freely. The piston is provided with a one-way air flow blocking valve, and is connected to the handle through a connecting rod. The handle is provided with two Spring, the other end of the spring is connected to the drainage bottle, the drainage tube is fixed with the bottle stopper as a whole, one end is bent and stretched into the drainage bottle and close to the bottom of the bottle, the liquid discharge port is located at the bottom of the drainage bottle; the drainage bottle is made of transparent Made of medical plastic, this invention is convenient for medical staff to operate, but it is difficult to control the negative pressure in the device during operation, and for symptoms that require small flow and slow drainage, repeated pressing will increase the workload of medical staff
