Embodiment Construction

[0017] like figure 1 The shown pressure measurement and drainage catheter has a drainage tube main body 1, and the drainage tube main body is a silicone drainage tube. The side wall of the main body of the drainage tube is provided with a niche, and an inelastic sealing film 3 is provided at the opening of the niche, and the sealing film is a polymer resin film. The sealing film is a loose film and forms a closed pressure measuring cavity 2 with the niche, and the pressure measuring cavity can hold 4ml of liquid or gas. The pressure-measuring sac 2 is connected with a liquid-filled thin tube 4 and a pressure-measuring thin tube 5, and the liquid-filled thin tube and the pressure-measuring thin tube are drawn out from the main wall of the drainage tube, and the outlet end of the pressure-measuring thin tube is connected to On the pressure gauge 7 or the electronic pressure gauge, the port of the liquid-filled capillary is connected to the liquid-filled joint 6 . The liquid fi...

Abstract

The invention discloses a pressure-measuring drainage catheter and a pressure measuring method. The drainage catheter comprises a drainage catheter main body; a recess is arranged in the side wall on the end side of the drainage catheter main body; an inelastic sealing film which is a loosened film is arranged at the opening of the recess; an enclosed pressure measuring cavity is formed by the sealing film and the recess; the pressure measuring cavity communicates with a liquid-filling thin tube and a pressure-measuring thin tube; the liquid-filling thin tube and a pressure-measuring thin tube are lead out from the drainage catheter main body wall; an outlet end of the pressure-measuring thin tube is connected to a pressure measuring scale or an electronic pressure gauge; and a port of the liquid-filling thin tube is connected to a liquid-filling joint. Compared with the prior art, the pressure-measuring drainage catheter is simple in structure and low in cost, the pressure-measuring tube is always in a smooth state, the intracranial pressure (ICP) can be sensitively shown, and the measurement is accurate.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pressure measurement and drainage catheter and a pressure measurement method for drainage of body fluids and pressure measurement in the body, especially intracranial pressure (ICP) measurement. Background technique [0002] my country is a country with a high incidence of craniocerebral trauma and cerebral hemorrhage, and the number of craniotomy operations per year ranks first in the world. After each craniotomy, 1 to 4 drainage tubes are placed. The measurement of intracranial pressure (ICP) is accurate and sensitive to reflect the changes in the condition of patients with craniocerebral diseases. It is recommended by many parties, but it is difficult to popularize due to the limitation of equipment, high-value consumables and expensive maintenance. The current ventricular drainage tube can be used as one of the ways to observe ICP when it is unobstructed...
