Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with specific embodiments, so that those skilled in the art can understand.

[0034] Such as Figure 1~2 Shown is a monitoring and alarm system for pipeline blockage of a negative pressure sealing drainage system. The monitoring and alarm system is installed on the negative pressure sealing drainage system. The negative pressure sealing drainage system includes a porous dressing 2 in contact with the patient's tissue site 1, a porous dressing 2 The back is connected with a drainage tube 4, and the porous dressing 2 is wrapped with a biological semipermeable membrane 3 for sealing; the other end of the drainage tube 4 is connected with a liquid collection bottle 6,

[0035] The upper part of the inner wall of the liquid collection bottle 6 is provided with a filter 7, and the filter 7 communicates with the first gas buffer chamber 9 through the gas guide tube 8; the first gas buffer chamber 9 ...

Abstract

The invention discloses a monitoring and alarming system for pipeline blockage of a negative-pressure closed drainage system. The monitoring and alarming system comprises a main control unit, a firstsensor, an alarm, a second sensor and a fluid monitoring tube; the main control unit is used for respectively comparing the negative pressure value of a first gas buffer chamber and the pressure valueof a second gas buffer chamber with the maximum set value of the negative pressure source and a user-preset value, comprehensively judging whether the drainage pipeline of the negative pressure closed drainage system is blocked or not, controlling to adjust the negative pressure value of the first gas buffer chamber to judge a blocking point when the drainage pipeline is blocked, and sending a blocking point alarm signal to an alarm; and the alarm sends out an alarm signal when receiving the alarm signal of the main control unit. The monitoring and alarming system can achieve safe and effective drainage, facilitate automatic removal of blockage and reduce unnecessary workloads medical staff and unnecessary tension of a patient.

Description

technical field [0001] The invention relates to tissue treatment equipment, in particular to a monitoring and alarm system for pipeline blockage of a negative pressure closed drainage system. Background technique [0002] Clinical research and practice have shown that the use of negative pressure sealing drainage technology in the tissue site can remove exudate and infectious tissue in the tissue site in a timely manner, keep the tissue site in a clean and dry environment, promote wound edge closure, reduce edema, and promote the growth and shortening of granulation tissue treatment time. However, in the process of negative pressure sealing drainage, pipeline blockage occurs from time to time, and the purpose of effective drainage cannot be achieved if the pipeline is blocked, and tissue exudate will accumulate in tissue parts. Since the monitoring pipeline is not directly connected to the negative pressure source, the negative pressure in the pipeline is equal everywhere, ...
