Medical couplant smearing auxiliary system and control method thereof

Abstract

The invention relates to a medical couplant smearing auxiliary system. The system comprises a high-viscosity substance pump and a control system. The high-viscosity substance pump comprises a container, an air inlet pipeline and a material taking device; an opening of the container is connected with a feed opening of the material taking device; one end of the air inlet pipeline extends into the tail end of the container; the air inlet pipeline is used for sending high-pressure gas into the container so as to form negative pressure inside and outside the container; and the material taking device is used for extracting a couplant in the container. The control system comprises a switch, a driving motor, a controller, a monitoring unit and a high-pressure air pump, wherein the monitoring unitis used for timing according to a given time when the switch is opened. When timing is started, the controller controls the driving motor and the high-pressure air pump to operate, the motor is drivento drive the material taking device to work while air is pressurized into the container, and the couplant is taken out from a discharging opening of the material pump under action of the high-pressure air pump and the material taking device. The monitoring unit is further used for breaking connection between the controller and the switch when timing is carried out to a given time, and then the monitoring unit waits for a next working circle. The system provided by the invention can be used to extract the couplant quantitatively, uniformly and smoothly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a medical coupling agent application auxiliary system and a control method thereof. Background technique [0002] Medical coupling agent is a medical product composed of water-based polymer gel. Its PH value is neutral, non-toxic and harmless to the human body, not easy to dry, not easy to rancid, clear ultrasonic imaging, high viscosity, non-greasy The probe is easy to slide, can moisten the skin, eliminate the air on the skin surface, has good lubricating performance, and is easy to deploy. During ultrasonic testing, the air between the probe and the patient's skin will hinder the transmission of ultrasonic waves into the human body. In order to obtain high-quality and clear images, it is necessary to use an ultrasonic gel to connect the probe to the patient's body surface. The purpose of using an ultrasonic coupling agent is firstly to fill the tiny gaps between the contact sur...

Problems solved by technology

[0003] During clinical use, the couplant is packed in a special bottle, and medical workers need to squeeze the couplant in the bottle onto the ultrasound probe by hand, because the couplant has a very high viscosity and it is very laborious to squeeze out

Medical workers may need to repeatedly squeeze the couplant hundreds of times during working hours. The whole process is mechanical and laborious, which increases the workload and reduces work efficiency. At the same time, it also causes hand discomfort.

If the viscosity is too high, it is difficult for ordinary liquid pumps to pump out the couplant. At present, there is no auxiliary equipment on the market to solve the problem of couplant extrusion and smearing
