Ultrasonic department coupling agent smearing apparatus for preventing cross infection, and smearing method of smearing apparatus

Abstract

The invention discloses ultrasonic department coupling agent smearing apparatus for preventing cross infection. The smearing apparatus comprises a coupling agent storage box, a sealing cover, a smearing head, a push rod and a protective shell, wherein the upper end of the coupling agent storage box is in threaded connection with the sealing cover, a telescopic rod is arranged at the lower end of the coupling agent storage box, the inside structure of the telescopic rod is of a hollow structure, the smearing head is arranged at the bottom end of the telescopic rod, a connecting rod is fixedly connected with the upper surface of the smearing head, a control valve is fixedly connected with the top end of the connecting rod, sliding pieces are arranged on two sides of the control valve, and one ends of the two sliding pieces are fixedly arranged at the side edge of the coupling agent storage box. Through the arranged control valve, the opening and closing of the bottom end of the couplingagent storage box can be controlled by the position movement of the control valve, and a residual coupling agent can be discharged, so that the cross infection, and the influence on the next use of aprobe after solidification of the residual coupling agent are prevented.

Description

Technical field[0001]The invention relates to the technical field of medical device replication devices, in particular to a coupling agent smearing device and smearing method for ultrasound to prevent cross-infection.Background technique[0002]B-ultrasound is an imaging discipline that uses the physical characteristics of ultrasound for diagnosis and treatment, called ultrasound medicine. It has a wide range of clinical applications and has now become an indispensable diagnostic method in modern clinical medicine. In B-ultrasound examination of the body, a layer of coupling agent must be applied between the B-ultrasound probe and the skin. It is a water-soluble polymer colloid. It is used to remove the air between the probe and the object to be measured. It can penetrate into the test object effectively to achieve the purpose of effective detection.[0003]Medical coupling agent is a medical product composed of a new generation of water-based polymer gel. Its PH value is neutral, non-t...

Problems solved by technology

[0004] In the process of ultrasound examination, it is necessary to apply couplant to the patient, so it is necessary to use a couplant application device. At present, most of the couplant application devices on the market have the following problems during use; 1. Most of the coupling agent application devices currently on the market During the use of the agent application device, the control valve is generally opened manually, and the coupling agent is applied to the patient. When changing the application position, the control valve needs to be closed, and the control valve is opened again when applying. This method is cumbersome and waste time

2. Due to the high viscosity of the couplant itself, it is difficult for the couplant to be discharged from the inside of the smearing device during the smearing process. At present, most of the couplant smearing devices on the market are generally equipped with a push plug inside the smearing device. Manually push the push plug to squeeze out the couplant, which is laborious

3. After using the probe, if the remaining coupling agent in the applicator head is not discharged, on the one hand, there is a risk of cross-infection when it is used on other inspected persons; The coupling agent at the place is cured, which will affect the normal use next time
